[0025] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0026] In the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] Such as Figures 1-5As shown in the figure, a rack for machinery in this embodiment includes a base body 1, a first clamping plate 2, a tooth part 3 and a second clamping plate 4. A plurality of mounting grooves 11 are formed at the top of the base body 1. A first clamping plate 2 is arranged on one side of the plurality of mounting grooves 11. A mounting part 31 is fixedly connected to the bottom of the tooth part 3. The mounting part 31 is inserted into the mounting groove 11. One side of the bottom of the second clamping plate 4 is fixedly connected with a positioning block 42. A through hole 43 is formed on one side of the positioning block 42. A plurality of threaded holes 12 are formed on the side of the base body 1 away from the first clamping plate 2, and the plurality of threaded holes 12 correspond to the plurality of mounting grooves 11 one by one. A bolt 5 is inserted into the through hole 43, and the bolt 5 passes through the through hole 43 and is threadedly connected with the threaded hole 12 to fix the second clamping plate 4 in the mounting groove 11. The first clamping plate 2 and the second clamping plate 4 are respectively located on both sides of the mounting part 31 in the mounting groove 11. A plurality of tooth grooves 32 are formed on both sides of the mounting part 31. A plurality of first teeth 21 are fixedly connected to the side of the first clamping plate 2 close to the mounting part 31. A plurality of second teeth 41 are fixedly connected to the side of the second clamping plate 4 close to the mounting part 31. The tooth grooves 32 on both sides of the mounting part 31 are respectively meshed with the first teeth 21 and the second teeth 41 to fix the mounting part 31, so as to achieve the purpose of fixing the tooth part 3.

[0028] Embodiment 1: As Figure 2 and Figure 3 shown, first sliding strips 22 are fixedly connected to both sides of the first clamping plate 2. First sliding grooves 13 are formed at positions corresponding to the first sliding strips 22 on the inner walls of both sides of the mounting groove 11. The first clamping plate 2 is slidably connected in the first sliding grooves 13 through the first sliding strips 22. Because the first teeth 21 need to be arranged on one side of the first clamping plate 2, it is relatively simple to separately process the first clamping plate 2 and the base body 1 during the processing. After the first clamping plate 2 is completed, it needs to be installed in the mounting groove 11. By designing the sliding connection method, it is convenient to assemble the first clamping plate 2 into the mounting groove 11 later.

[0029] Embodiment 2: As Figure 2 and Figure 5 shown, second sliding strips 44 are fixedly connected to both sides of the second clamping plate 4. Second sliding grooves 14 are formed at positions corresponding to the second sliding strips 44 on the inner walls of both sides of the mounting groove. The second sliding strips 44 are slidably connected in the second sliding grooves 14. During use, the mounting part 31 applies force to the second clamping plate 4. Since the position of fixing the second clamping plate 4 is below, after the second clamping plate 4 is stressed, the force will change direction to an inclined force with the positioning block 42 as the origin. Therefore, the connection between the second clamping plate 4 and the positioning block 42 is prone to deformation. By sliding the second sliding strips 44 in the second sliding grooves 14, the direction of the force can be restricted to avoid the force from tilting. Therefore, the problem of deformation at the connection between the second clamping plate 4 and the positioning block 42 can be prevented, and the reliability of the structure is improved.

[0030] Embodiment 3: As Figure 1, 2 and Figure 5 As shown in 2 and Figure 5 , a first groove 15 is provided at a position on one side of the base body 1 corresponding to the threaded hole 12, and the positioning block 42 is inserted into the first groove 15. With this design, the positioning block 42 will not protrude from the side of the base body 1, improving the overall aesthetics and not affecting the fixation of the base body 1 later.

[0031] Example 4: As shown in Figure 1 and Figure 5 a second groove 45 is provided at a position on one side of the positioning block 42 corresponding to the through hole 43, and the head of the bolt 5 is inserted into the second groove 45. With this design, the head of the bolt 5 will not protrude from the side of the base body 1, improving the overall aesthetics and not affecting the fixation of the base body 1 later.

[0032] Example 5: Rubber pads are fixedly connected to the surfaces of the first ratchet 21 and the second ratchet 41. The rubber pads are elastic and can improve the firmness of the engagement between the first ratchet 21 and the second ratchet 41 and the tooth grooves 32.

[0033] The working principle of the present utility model is as follows: When in use, the first clamping plate 2 is slidably connected to the first sliding groove 13 through the first sliding strip 22, and then the tooth part 3 is inserted into the installation groove 11 through the installation part 31. Slide the tooth part 3 to one side of the first clamping plate 2 so that the tooth groove 32 on one side of the installation part 31 engages with the first engagement 21 on the first clamping plate 2. Then insert the second clamping plate 4 into the installation groove 11 from one side of the base body 1. At this time, the second ratchet 41 engages with the tooth groove 32 on the other side of the installation part 31. Finally, insert the bolt 5 into the through hole 43 and thread it with the threaded hole 12 to fix the second clamping plate 4 to complete the assembly. When disassembling and replacing the damaged tooth part 3 later, loosen the corresponding bolt 5, slide the second clamping plate 4 outward from the base body 1, and then move the tooth part 3 so that the tooth grooves 32 are disengaged from the first ratchet 21 and the second ratchet 41 respectively, and the tooth part 3 can be disassembled, which is time-saving and labor-saving.

[0034] Compared with the prior art, the present utility model has the following beneficial effects compared with the prior art:

[0035] 1. When repairing and replacing the damaged tooth part 3 later, loosen the corresponding bolt 5, slide the second clamping plate 4 outward from the base body 1, and then move the tooth part 3 so that the tooth grooves 32 are disengaged from the first ratchet 21 and the second ratchet 41 respectively, and the tooth part 3 can be disassembled. The operation is simple, so the later maintenance is time-saving and labor-saving.

[0036] 2. The first clamping plate 2 and the base body 1 are manufactured in a split manner, which facilitates the manufacture of the product. And the first clamping plate 2 is slidably connected to the first sliding groove 13 in the installation groove 11 through the first sliding strip 22, which facilitates the later assembly of the rack.

[0037] 3. By setting the second slider 44 and the second chute 14, with the second slider 44 being slidably connected within the second chute 14, the direction of the force exerted by the mounting portion 31 on the second clamping plate 4 is restricted, preventing the change of the force direction, thereby avoiding the problem of deformation at the connection between the second clamping plate 4 and the positioning block 42 and improving the structural reliability.
