DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 , the utility model provides an embodiment: a door slide reinforcement structure, including a supporting cross frame 4, a guide device 1 is slidably inserted in the front end of the supporting cross frame 4, a positioning device 2 is symmetrically fixedly installed at the bottom of the front end of the guide device 1, and an alignment device 3 is slidably installed at the front end of the guide device 1. The guide device 1 includes a gear 5, an alignment sleeve 6 and a door slide 7. The gear 5 is rotatably installed at the bottom of the front end of the door slide 7, and the alignment sleeve 6 is symmetrically fixedly installed at the front end of the door slide 7. The positioning device 2 includes a rack 8, a movable rod 9, a reset spring 10, a support cavity 11 and a positioning plug 12. The reset spring 10 is fixedly installed at one end inside the support cavity 11, the positioning plug 12 slides through the support cavity 11 and is connected to one end of the reset spring 10, the movable rod 9 slides through the support cavity 11 and is connected to the end of the positioning plug 12 away from the positioning plug 12, and the rack 8 is fixedly installed at the end of the movable rod 9 away from the reset spring 10.

[0021] The alignment device 3 includes a layer door panel 13, an L-shaped alignment plate 14 and a side end bracket 15. The L-shaped alignment plate 14 is symmetrically fixedly installed on the front end top of the layer door panel 13, and the side end bracket 15 is fixedly installed on the top of both sides of the layer door panel 13. A mounting hole is opened through the front end top of the layer door panel 13, so that bolts can be easily passed through the layer door panel 13 and fastened to the door slide 7.

[0022] The L-shaped alignment plate 14 is slidably inserted into the front end of the alignment sleeve 6, and the support cavity 11 is symmetrically fixedly installed at the front end of the door slide 7. The support cavity 11 is located on both sides of the gear 5, and the side end bracket 15 can be limited at both ends.

[0023] The gear 5 is meshed with the two racks 8. When the gear 5 rotates, the two positioning blocks 12 can be driven to move simultaneously.

[0024] A square hole is formed inside the side end of the side bracket 15 close to the L-shaped alignment plate 14 to facilitate the insertion of the positioning plug 12 into the side bracket 15 .

[0025] The rear end of the door slide plate 7 is symmetrically fixed with a clamping key, and the front end of the supporting cross frame 4 is provided with a clamping groove, which can ensure that the door slide plate 7 moves in a straight line.
