[0023] For the convenience of understanding the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present utility model are given in the drawings. However, the present utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosed content of the present utility model more thorough and comprehensive.

[0024] Please refer specifically to the attached Figures 1 - 5As shown in the figure, the utility model provides a technical solution: a gantry absorbing wall, which includes multiple groups of frames 10. Absorbing plates 11 are arranged in each of the multiple groups of frames 10. A splicing mechanism is arranged between the multiple groups of frames 10. The splicing mechanism includes a sliding rod 20. An elongated groove 101 is formed inside the lower right end of the frame 10. The sliding rod 20 is slidably installed on one side of the inner wall of the elongated groove 101. Limiting grooves 102 are formed on the inner walls of two adjacent sides of the elongated groove 101. A first clamping block 21 and a second clamping block 22 are respectively slidably installed in the two limiting grooves 102. The first clamping block 21 is fixedly connected to one end of the sliding rod 20. A transmission rod 23 is arranged between the sliding rod 20 and the second clamping block 22. An elongated hole 201 and a groove 221 are respectively formed on one side surfaces of the sliding rod 20 and the second clamping block 22. Two ends of the transmission rod 23 are respectively rotatably installed in the elongated hole 201 and the groove 221. Two clamping grooves 108 are respectively formed at the lower left side and the upper right side of the frame 10. The first clamping block 21 and the second clamping block 22 are respectively adapted to the two clamping grooves 108.

[0025] In this embodiment, the splicing mechanism further includes a sliding plate 202 fixedly connected to the end of the sliding rod 20 away from the first clamping block 21. A second spring 25 is fixedly installed between the end of the sliding plate 202 away from the sliding rod 20 and the inner wall of the elongated groove 101.

[0026] Specifically, when assembling multiple groups of frames 10, the right side and the lower side of one frame 10 slide on the upper side and the left side of the other two frames 10. Under extrusion, the first clamping block 21 and the second clamping block 22 push the sliding rod 20 to slide in the elongated groove 101, squeezing the second spring 25. When the first clamping block 21 and the second clamping block 22 move to the clamping grooves 108 on the upper side and the left side of the other two frames 10, under the elastic force of the second spring 25, the sliding rod 20 directly or through the transmission rod 23 pushes the first clamping block 21 and the second clamping block 22 to be respectively clamped in the two clamping grooves 108, facilitating the assembly of the absorbing wall.

[0027] In this embodiment, a through hole 103 is formed on one side of the frame 10 close to the elongated groove 101. The through hole 103 communicates with the elongated groove 101. The through hole 103 is arranged on the side close to the second spring 25. A push rod 24 is fixedly connected to one side of the sliding rod 20 close to the sliding plate 202. One end of the push rod 24 extends out of the through hole 103 and is slidably installed in the through hole 103.

[0028] When the gantry absorbing wall is to be dismantled, the push rod 24 is manually pushed, and the push rod 24 slides upward in the through hole 103, driving the slide plate 202 on the slide bar 20 to move in the direction of the second spring 25, so that the second spring 25 is in an extruded state, and at the same time driving the first clamping block 21 on one side of the slide bar 20 to slide in one of the limiting grooves 102 and disengage from the clamping groove 108 in the adjacent frame 10. When the slide bar 20 moves, the elongated hole 201 moves accordingly, driving one end of the transmission rod 23 to move, and the other end of the transmission rod 23 pulls the second clamping block 22 to slide in the other limiting groove 102 and disengage from the clamping groove 108 in the frame 10 on the other side of the frame 10, thereby releasing the lock between the adjacent frames 10, making it easy to dismantle multiple groups of frames 10, and the operation is relatively simple.

[0029] In this embodiment, a U-shaped clamping ring 12 is rotatably installed on the left upper end of the frame 10, and an arc-shaped clamping hole 107 adapted to the U-shaped clamping ring 12 is opened on the right upper end of the frame 10. The U-shaped clamping ring 12 on the left side of one frame 10 can be rotatably engaged in the arc-shaped clamping hole 107 in the frame 10 on the adjacent side, thereby increasing the connection stability between multiple groups of frames 10.

[0030] In this embodiment, a U-shaped groove 109 is formed on the inner wall of the frame 10 , and the absorbing plate 11 is slidably installed in the U-shaped groove 109 , so that the absorbing plate 11 can be easily removed from the frame 10 .

[0031] In this embodiment, L-shaped connection holes 104 are provided on the upper surfaces of the two sides of the upper end of the frame 10 close to the absorbing plate 11, and rotating shafts 13 are rotatably installed in the two L-shaped connection holes 104. The lower ends of the two rotating shafts 13 are fixedly strung with clamping rods 14, and the two clamping rods 14 are respectively slidably engaged with the upper surfaces of the absorbing plate 11. Two adjustment mechanisms are provided between the two clamping rods 14 and the frame 10, and the position of the absorbing plate 11 is fixed by the two clamping rods 14.

[0032] In this embodiment, the adjustment mechanism includes a connecting block 106 fixedly connected to one end of the frame 10 away from the two clamping rods 14, an L-shaped slide groove 105 is opened on one side of the upper end of the connecting block 106, one side of the L-shaped slide groove 105 is connected with the L-shaped connecting hole 104, an L-shaped moving rod 16 is slidably installed in the L-shaped slide groove 105, and a plurality of clamping teeth 161 are evenly fixedly installed on the side of the L-shaped moving rod 16 close to the L-shaped connecting hole 104, and a circular gear 15 is fixedly arranged on the upper end of the rotating shaft 13, and the circular gear 15 is meshed with the plurality of clamping teeth 161.

[0033] In this embodiment, a first spring 17 is fixedly mounted on the inner wall of one side of the L-shaped moving rod 16 and the L-shaped sliding groove 105 to facilitate the resetting of the L-shaped moving rod 16 .

[0034] Specifically, by pushing the L-shaped moving rod 16 to slide in the L-shaped sliding groove 105 to squeeze the first spring 17, when the L-shaped moving rod 16 slides, a plurality of latching teeth 161 on one side of the L-shaped moving rod 16 will push the circular gear 15 to rotate, so that the rotating shaft 13 drives the latching rod 14 to rotate toward the L-shaped connecting hole 104. When the latching rod 14 is completely separated from the surface of the absorbing plate 11, the absorbing plate 11 in the frame 10 can be pulled out. Otherwise, the position of the absorbing plate 11 can be locked to prevent the absorbing plate 11 from sliding out of the frame 10.

[0035] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
