Drain clog remover

Abstract

The present invention discloses a drain clog remover, including an elongate member for removing a clog from a pipe, a first case for accommodating the elongate member in a form of a coil, which is annular and defines an opening in its inner circumferential surface, a second case sleeved on the first case and configured to slide relative to the first case; a stop member, which is connected to the second case and configured to prevent dislodgement of the elongate member from the first case during retraction of the elongate member. The present invention can effectively prevent dislodgement of the elongate member from the first case during stowing, making the drain clog remover more convenient to use.

         2 . The drain clog remover of  claim 1 , wherein the stop member comprises an extension extending along a circumferential direction of the first case from a body of the second case, the extension covering part of the first case so that the rest of the first case forms a turning member. 
     
     
         3 . The drain clog remover of  claim 2 , wherein a line connecting an end of the body of the second case and a center of a circle defined by the first case forms an angle of 90 degrees with a line connecting an end of the extension and the center of the circle defined by the first case. 
     
     
         4 . The drain clog remover of  claim 1 , wherein the stop member comprises a stop ring extending from the second case along the inner circumferential surface of the first case, one end of the stop ring connected to one end of the second case, the other end of the stop ring connected to the other end of the second case such that the stop ring defines a circle together with an inner circumferential surface of the second case. 
     
     
         5 . The drain clog remover of  claim 4 , wherein at least part of the stop ring is inserted in the first case. 
     
     
         6 . The drain clog remover of  claim 5 , wherein the stop member further comprises a rolling member rotatably connected to the stop ring. 
     
     
         7 . The drain clog remover of  claim 1 , wherein the stop member comprises a bracket arranged in a circumferential area of the first case, the bracket comprising at least one bracket arm, one end of the bracket arm connected to the second case, the other end defining a stop portion inserted in the first case. 
     
     
         8 . The drain clog remover of  claim 7 , wherein the bracket comprises a first bracket arm and a second bracket arm, one end of the first bracket arm connected to one end of the second case, one end of the second bracket arm connected to the other end of the second case, the other end of the first bracket arm and the other end of the second bracket arm joined to each other and together defining the stop portion at the joint. 
     
     
         9 . The drain clog remover of  claim 7 , wherein the stop member further comprises a rolling member rotatably connected to the stop portion. 
     
     
         10 . The drain clog remover of  claim 1 , wherein the second case is made up of a first portion and a second portion, which are disposed in opposition to each other and located at two respective axial ends of the first case. 
     
     
         11 . The drain clog remover of  claim 10 , wherein the stop member comprises a stop portion, which extends along the inner circumferential surface of the first case from the first portion so that the stop portion and the first portion define an L-shaped or U-shaped cross-sectional shape. 
     
     
         12 . The drain clog remover of  claim 10 , wherein the stop member comprises a stop lever disposed on at least one end of the first portion, the stop lever having a free end inserted within the first case. 
     
     
         13 . The drain clog remover of  claim 12 , wherein the stop member further comprises a rolling member rotatably connected to the free end of the stop lever. 
     
     
         14 . The drain clog remover of  claim 12 , wherein the stop lever is integrally formed with the second case. 
     
     
         15 . The drain clog remover of  claim 12 , wherein a pressing block is formed at the free end of the stop lever, the pressing block contacting and pressing the elongate member across a curved surface. 
     
     
         16 . The drain clog remover of  claim 15 , wherein the pressing block is provided thereon with a metal washer in contact with the elongate member. 
     
     
         17 . The drain clog remover of  claim 12 , wherein the stop lever is rotatably connected to the second case and a resilient member is connected to the stop lever and the second case and exerts a pre-tensioning force on the stop lever toward the elongate member. 
     
     
         18 . The drain clog remover of  claim 15 , wherein the resilient member is a torsion spring disposed on a rotating shaft for the stop lever and the second case. 
     
     
         19 . The drain clog remover of  claim 10 , wherein the second portion defines an outlet guide channel serving as a channel for guiding out the elongate member. 
     
     
         20 . The drain clog remover of  claim 19 , wherein the outlet guide channel is tangent to a circumference of the first case.
