Title: Leg tube sliding locking mechanism for opening and closing folding tent

Description:
BACKGROUND 
     Technical Field 
     The invention belongs to the technical field of folding tents, and specifically relates to a leg tube sliding locking mechanism for opening and closing a folding tent. 
     Description of Related Art 
     A folding tent is unfolded when used and folded and contracted when not used and has the advantages of sunshade, rain shielding and convenience in carrying, so that said tent is widely used in daily life. However, during folding and contraction of the existing folding tent, it is required to press a jump bead arranged on a leg tube of the folding tent for unlocking, since the hand of an operator make direct contact with the jump bead, the hand clamping phenomenon occurs easily, and certain injuries may be caused to the operator due to the excessively large folding force. In addition, the psychological shadow may be left for the operator in case of the hand clamping condition, resulting in scrupulousness or fear of pressing during pressing of the jump bead later and inconvenience in use. 
     SUMMARY 
     In view of the problems in the prior art, the purpose of the present invention design is to provide a leg tube sliding locking mechanism for opening and closing a folding tent. 
     The invention is implemented through the following technical solutions. 
     A leg tube sliding locking mechanism for opening and closing the folding tent, characterized in that the leg tube sliding locking mechanism includes a sliding support sleeved on a leg tube, a jump bead and a V-shaped spring, one end of the V-shaped spring is connected to the jump bead, the other end of the V-shaped spring is fixed to an inner wall of the leg tube, a bushing is installed on an inner wall of the sliding support in a fitted manner, an upper end of the bushing extends downwards to form a pressing sheet, the pressing sheet has a lower end extending outwards to a lower end of the sliding support, and the pressing sheet covers the jump bead. 
     The leg tube sliding locking mechanism for opening and closing the folding tent, characterized in that the bushing is correspondingly provided with a notch parallel to the pressing sheet. 
     The leg tube sliding locking mechanism for opening and closing the folding tent, characterized in that the upper end of the bushing is provided with an upper edge, and the upper edge has a lower end abutting against an upper end of the sliding support. 
     The leg tube sliding locking mechanism for opening and closing the folding tent, characterized in that the jump bead is provided with an installing hole, and one end of the V-shaped spring is inserted in the installing hole. 
     The leg tube sliding locking mechanism for opening and closing the folding tent, characterized in that a cross section of the V-shaped spring is round. 
     The leg tube sliding locking mechanism for opening and closing the folding tent, characterized in that the jump bead and the V-shaped spring are integrally arranged. 
     The leg tube sliding locking mechanism for opening and closing the folding tent, characterized in that a spring body of the V-shaped spring is of a plate-shaped structure. 
     The sliding support is internally provided with the bushing in a fitted manner such that the jump bead is not required to be directly pressed when the folding tent is folded and contracted, easy contraction is realized by pressing the pressing sheet having the large area, and the structure is easy to transform and realize.

     DESCRIPTION OF THE EMBODIMENTS 
     The present invention is further described in detail below with reference to the accompanying drawings of the specification, and specific embodiments are provided. 
     Embodiment 1 
     Disclosed is a leg tube sliding locking mechanism for opening and closing a folding tent, and the overall structure of the folding tent is shown in  FIG.  1   . The sliding locking mechanism is installed on a leg tube of the folding tent, and the specific structure of the sliding locking mechanism is shown in  FIGS.  2 - 6   . The sliding locking mechanism includes a sliding support sleeved on the leg tube, a jump bead and a V-shaped spring. One end of the V-shaped spring is connected to the jump bead, and the other end of the V-shaped spring is fixed to an inner wall of the leg tube. A bushing is further installed on an inner wall of the sliding support in a fitted manner, an upper end of the bushing extends downwards to form a pressing sheet, and the pressing sheet has a lower end extending outwards to a lower end of the sliding support to cover the jump bead. The jump bead is provided with an installing hole, one end of the V-shaped spring is inserted in the installing hole, a spring body of the V-shaped spring is cylindrical, and the cross section thereof is round. 
     Furthermore, the bushing is made of a plastic material and is correspondingly provided with a notch parallel to the pressing sheet, the upper end of the bushing is provided with an upper edge, and the upper edge has a lower end abutting against an upper end of the sliding support. 
     Embodiment 2 
     As shown in  FIGS.  7 - 8   , the structure of this embodiment is basically the same as that of embodiment 1, and the difference lies in the different specific structure of the V-shaped spring, wherein the V-shaped spring in the embodiment and the jump bead are of an integrated structure, and the spring body of the V-shaped spring is of the plate-shaped structure. 
     When the folding tent is opened, the sliding support drives the bushing to move upwards, after a bottom portion of the sliding support moves upwards to an upper portion of a position where the jump bead is located, the jump bead pops up and blocks the lower end of the sliding support and abuts against the back of the elastic pressing sheet of the bushing, and the tent is locked. When the folding tent is closed, all that is required is to press the pressing sheet, the jump bead retracts to the inside of the leg tube, the sliding support moves downwards, and the tent is closed. In the opening and closing processes, fingers are prevented from directly pressing the jump bead, and the hand clamping phenomenon is avoided.
