[0005] This utility model is achieved through the following technical solution: a wear-resistant plastic shell with reinforcing ribs, comprising a plastic shell body and multiple side reinforcing ribs. The inner side surface of the plastic shell body is provided with multiple connecting grooves. The side reinforcing ribs are distributed in a rectangular structure inside the plastic shell body. The outer side surface of the side reinforcing ribs protrudes to form connecting strips, which are inserted into the corresponding connecting grooves. One end of each side reinforcing rib is bent to form a top reinforcing rib. The surface of any reinforcing rib is provided with a positioning groove, and a positioning block is provided in each positioning groove. One end of each positioning block protrudes to form an extension.

[0006] As a preferred technical solution, each side reinforcing rib is provided with a groove, and each row of side reinforcing ribs has a pressure rod in the groove. Both ends of the pressure rod are equipped with screws. The side of the plastic shell body is provided with a through hole opposite the screw. The other end of the screw extends through the through hole to the outside and is threaded with a nut that moves the pressure rod toward the side of the plastic shell body.

[0007] As a preferred technical solution, the outermost top reinforcing rib on each row of side reinforcing ribs is shortened.

[0008] As a preferred technical solution, both the connecting groove and the connecting strip have trapezoidal cross-sections.

[0009] As a preferred technical solution, the top surface of the top reinforcing rib and the extension is flush with the open end face of the plastic shell body.

[0010] As a preferred technical solution, both the positioning groove and the positioning block are arranged in a "T" shape.

[0011] As a preferred technical solution, all compression bars are made of metal materials.

[0012] The beneficial effects of this utility model are: the utility model has a simple structure and the side reinforcing ribs are movable, so they can be inserted into the connecting slots at different positions and can be replaced, thereby increasing adaptability. Furthermore, one end of the side reinforcing rib is bent to form a top reinforcing rib, and an extension is installed on the top reinforcing rib. After the cover of the plastic shell body is closed, the inner side of the cover can simultaneously increase the load-bearing capacity of the cover with the top reinforcing rib and the extension.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein 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 with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention discloses a wear-resistant plastic shell with reinforcing ribs, comprising a plastic shell body 1 and multiple side reinforcing ribs 3. The inner side surface of the plastic shell body 1 is provided with multiple connecting grooves 11. The side reinforcing ribs 3 are distributed in a rectangular structure inside the plastic shell body 1. The outer side surface of the side reinforcing ribs 3 protrudes to form connecting strips 2, which are inserted into the corresponding connecting grooves 11. One end of each side reinforcing rib 3 is bent to form a top reinforcing rib 5. The surface of any reinforcing rib is provided with a positioning groove 12, and a positioning block 6 is provided in each positioning groove 12. One end of each positioning block 6 protrudes to form an extension 7.

[0022] The plastic shell is made of ABS plastic, which gives it good wear resistance and excellent overall performance, thus improving its usability.

[0023] In this embodiment, each side reinforcing rib 3 is provided with a groove 4, and each row of side reinforcing ribs 3 is provided with a pressure rod 10 in the groove 4. Both ends of the pressure rod 10 are equipped with screws 8. The side of the plastic housing body 1 is provided with a through hole opposite to the screw 8. The other end of the screw 8 extends through the through hole to the outside and is threadedly connected with a nut 9 that moves the pressure rod 10 toward the side of the plastic housing body 1.

[0024] In this embodiment, the outermost top reinforcing rib 5 on each row of side reinforcing ribs 3 is shortened so that the top reinforcing ribs on both sides do not touch.

[0025] In this embodiment, both the connecting groove 11 and the connecting strip 2 have trapezoidal cross-sections, preventing the connecting strip from directly detaching from the connecting groove.

[0026] In this embodiment, the top surfaces of the top reinforcing rib 5 and the extension 7 are flush with the open end face of the plastic shell body 1; the positioning groove 12 and the positioning block 6 are both arranged in a "T" shape, so that the positioning block can be stably placed in the positioning groove, and after the shell cover is closed, the inner side of the shell cover can abut against the positioning block, thereby pressing it tightly.

[0027] In this embodiment, the pressure rods 10 are all made of metal, which increases the load-bearing capacity. After the top reinforcing rib is compressed, its weight will act on the side reinforcing rib. The pressure rod can increase the load-bearing capacity at the groove, thus preventing the groove from breaking.

[0028] After the equipment is installed inside the plastic housing, different numbers of side reinforcing ribs can be inserted on the side of the plastic housing. The inserted side reinforcing ribs can avoid the equipment. As the side reinforcing ribs are inserted, the pressure rod can be inserted into the groove of each row of side reinforcing ribs. The screw on the pressure rod can pass through the through hole. After passing through, the nut can be threaded to the screw. The nut can drive the screw to move outward, so that the pressure rod can be pressed and fixed with the side reinforcing ribs to ensure the stability of the side reinforcing rib installation.

[0029] Furthermore, one end of the side reinforcing rib is bent to form the top reinforcing rib, and an extension is installed on the top reinforcing rib. After the cover of the plastic shell body is put on, the inner side of the cover can simultaneously increase the load-bearing capacity of the cover with the top reinforcing rib and the extension.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
