One-push instant canopy frame

Abstract

This application provides a one-push instant canopy frame that includes several support columns, outward telescopic units, and inward telescopic units; One outward telescopic unit is pivotally connected between two adjacent support columns; One support column is pivotally connected to one inward telescopic unit; The outward telescopic units and inward telescopic units constitute the top frame of the canopy; A push locking device is set at the lower end of the central top cover of the top frame; The push locking device includes a push member and a locking member. The push member is pivotally connected with the inward telescopic unit, and is equipped with a central rod. The locking member is slidably connected with the central rod; The locking member is used to lock the canopy in an unfolded state, and allows the canopy to be folded when the locking member is unlocked.

What is claimed is: 
     
         1 . A one-push instant canopy frame that is characterized by: It consists of several support columns, several outward telescopic units, and multiple inward telescopic units; One outward telescopic unit is pivotally connected between two adjacent support columns; One support column is pivotally connected to one inward telescopic unit; The outward telescopic units and inward telescopic units constitute the top frame of the canopy; A push locking device is set at the lower end of the central top cover of the top frame;
 The push locking device consists of a push member and a locking member; The push member is pivotally connected with the inward telescopic unit, and equipped with a central rod; The locking member is slidably connected with the central rod; The locking member is used to lock the canopy in an unfolded state, and allows the canopy to be folded when the locking member is unlocked;   During the unfolding process, an external force acts on the locking member to drive the push member to unfold the canopy, the locking member slides on the central rod, and the locking member is in an unlocked state; When the push member is pushed to a certain height, the locking member will slide to a locked state.   
     
     
         2 . The one-push instant canopy frame specified in  claim 1  is characterized by: The push member consists of a top cover and two or more push rods; The top cover is fixed at the upper end of the central rod;
 One end of the push rod is pivotally connected with the top cover, while the other end is pivotally connected with the inward telescopic unit. 
 
     
     
         3 . The one-push instant canopy frame specified in  claim 2  is characterized by: The locking member consists of sliding rod and two or more support rods; One end of the support rod is pivotally connected with the sliding rod, while the other end is pivotally connected with the push rod;
 There is a stopping member between the sliding rod and the central rod; When the top cover is pushed up to the pivot end between the push rod and the inward telescopic unit and below the pivot end, and the upward movement of the sliding rod and support rod is stopped by the stopping member, the locking member will move to the locking position. 
 
     
     
         4 . The one-push instant canopy frame specified in  claim 3  is characterized by: The central rod is equipped with a housing chamber for installing the stopping member; The sliding rod has at least one limiting hole;
 The sliding rod moves up and down along the central rod; The stopping member is placed in the housing chamber or the limiting hole. 
 
     
     
         5 . The one-push instant canopy frame specified in  claim 4  is characterized by: The housing chamber consists of an opening that is opposite to or staggered with the limiting hole; When the opening is opposite to the limiting hole, the stopping member is placed in the limiting hole. 
     
     
         6 . The one-push instant canopy frame specified in  claim 5  is characterized by: An unlocking member is set at the position corresponding to the limiting hole on the sliding rod; The unlocking member acts inward on the stopping member to place the stopping member in the housing chamber. 
     
     
         7 . The one-push instant canopy frame specified in  claim 1  is characterized by: The push member consists at least two push rods; The push locking device is pivotally connected with the top frame by the push rods. 
     
     
         8 . The one-push instant canopy frame specified in  claim 7  is characterized by: When the push locking device is unfolded, the top end of the central rod is lower than the pivot end between the push rod and the top frame. 
     
     
         9 . The one-push instant canopy frame specified in  claim 2  is characterized by: There are at least four push rods. 
     
     
         10 . The one-push instant canopy frame specified in  claim 3  is characterized by: There are at least four support rods.
