DETAILED DESCRIPTION

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

[0020] Example

[0021] See also Figure 1-6The utility model provides a technical solution: a combined door rear hook, comprising a circular plate 1, a plurality of first rectangular holes 2 are opened on the front inner wall of the circular plate 1, a first rectangular block 3 is slidably connected in the first rectangular hole 2, and the rear side of the first rectangular block 3 contacts the rear inner wall of the circular plate 1, and the front side of the first rectangular block 3 is fixedly connected to an L-shaped hook 4, and two second rectangular holes 5 are opened on the rear inner wall of the circular plate 1, and the second rectangular block 6 is slidably connected in the second rectangular hole 5, and the front side of the second rectangular block 6 contacts the front inner wall of the circular plate 1. Two rectangular plates 8 are slidably connected in the circular plate 1, and the two rectangular plates 8 are fixedly connected to a rectangular rod 9 on the side close to each other. The first rectangular block 3 and the second rectangular block 6 are both slidably sleeved on the outer side of the corresponding rectangular rod 9, and a groove 10 is opened at the end of the rectangular rod 9, and the front and rear sides of the groove 10 are opened. A stopper 11 and an arc-shaped hook are fixedly connected to the inner wall of the bottom of the groove 10 When the ball 14 is staggered with the arc block 12, the elastic force of the spring 20 causes the square rod 13 to drive the ball 14 to move between the stop block 11 and the arc block 12, and the L-shaped hook 4 and the U-shaped hook 7 are fixed. When one of the L-shaped hooks 4 is damaged, it is easy to remove it separately for replacement, and it is also easy to disassemble or combine the whole. In the process of moving, the volume is small, easy to carry and transport, which brings great convenience to the user.

[0022] In this embodiment, specifically: the balls 14 cooperate with the corresponding arc blocks 12, and the top ends of the two square rods 13 are fixedly connected to the same crossbar 15;

[0023] In this embodiment, specifically: the top of the crossbar 15 is fixedly connected to a round rod 16, the top of the round rod 16 extends to the top of the circular plate 1 and is fixedly connected to a round block 17;

[0024] In this embodiment, specifically: the circular plate 1 is slidably sleeved on the outside of the round rod 16, and the two square rods 13 are fixedly connected to the connecting block 18 on the side away from each other;

[0025] In this embodiment, specifically: a positioning rod 19 is fixedly connected to the top inner wall of the circular plate 1, and the connecting block 18 is slidably sleeved on the outer side of the corresponding positioning rod 19;

[0026] In this embodiment, specifically: a spring 20 is fixedly connected between the top of the connecting block 18 and the top inner wall of the circular plate 1, and the spring 20 is movably sleeved on the outer side of the corresponding positioning rod 19;

[0027] In this embodiment, specifically: a pull block 21 is fixedly connected to one side of the two rectangular plates 8 that are away from each other, and a U-shaped hook 7 is fixedly connected to the rear side of the second rectangular block 6 .

[0028] When the L-shaped hook 4 is damaged and needs to be replaced or disassembled as a whole, the circular block 17 is held and the cross bar 15 is driven upward by the circular rod 16. The cross bar 15 drives the two square rods 13 to move upward. The square rod 13 drives the corresponding connecting block 18 to move. The connecting block 18 slides on the outside of the corresponding positioning rod 19 and compresses the spring 20. The square rod 13 drives the ball 14 to move, and the square rod 13 moves out from between the corresponding stop block 11 and the arc block 12. Then, the pulling block 21 is moved in the direction away from each other. The pulling block 21 drives the rectangular plate 8 to move. The rectangular plate 8 drives the rectangular rod 9 to move, and the rectangular rod 9 is separated from the corresponding first rectangular block 3 and the second rectangular block 6. At this time, the L-shaped hook 4 is moved forward, and the L-shaped hook 4 drives the first rectangular block 3 to move out of the first rectangular hole 2. At this time, the damaged L-shaped hook 4 can be replaced. At the same time, the U-shaped hook 7 is moved backward, and the U-shaped hook 7 drives the second rectangular block 6 to separate from the second rectangular hole 5, thereby reducing the overall volume and facilitating carrying and transportation.

[0029] When assembling, move the L-shaped hook 4 backward, the L-shaped hook 4 drives the first rectangular block 3 to move from the first rectangular hole 2 to the circular plate 1, move the U-shaped hook 7 backward, the U-shaped hook 7 drives the second rectangular block 6 to move from the second rectangular hole 5 to the circular plate 1, move the pull block 21 in the direction of approaching each other, the pull block 21 drives the rectangular plate 8 to move, the rectangular plate 8 drives the rectangular rod 9 to move, so that the first rectangular block 3 and the second rectangular block 6 are slidably sleeved on the outside of the rectangular rod 9, the rectangular rod 9 drives the arc block 12 to move, and the arc block 12 squeezes the corresponding ball 14 during the movement. Under the action of the squeezing force, the ball 14 drives the square rod 13 to move upward, and the square rod 13 drives the corresponding connecting block 18 to move, and the connecting block 18 is in the opposite direction. The outer side of the corresponding positioning rod 19 slides and compresses the spring 20. When the ball 14 is offset from the arc surface of the corresponding arc block 12, the spring 20 in the compressed state is reset, and the elastic force of the spring 20 drives the connecting block 18 to move downward, and the connecting block 18 drives the square rod 13 to move downward, and the square rod 13 drives the ball 14 to move between the corresponding stopper 11 and the arc block 12, so that the L-shaped hook 4 and the U-shaped hook 7 are fixed, thereby forming a combined door rear hook. When one of the L-shaped hooks 4 is damaged, it is convenient to remove it separately for replacement, and it is also convenient to disassemble or combine the whole. In the process of moving, the volume is small, easy to carry and transport, which brings great convenience to the user.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
