Description

Technical Field

[0001] This utility model relates to the field of protective devices, and in particular to a wall-mounted protective cover. Background Technology

[0002] In existing conveying equipment, protective covers are installed in many moving parts to ensure personnel safety. Usually, the protective covers are connected to the equipment by bolts. Installation and disassembly require a certain amount of operation time. In the case of a large number of new equipment installations, some equipment has bolts that are inconvenient to operate due to their design, which takes up a lot of installation time and increases the installation cost for on-site personnel. Utility Model Content

[0003] The purpose of this utility model is to provide a wall-mounted protective cover, which aims to solve the technical problem of inconvenient installation of existing protective covers.

[0004] To achieve the above objectives, the solution provided by this utility model is as follows: A wall-mounted protective cover includes a cover body and at least two hooks. The cover body includes a back panel and at least two surrounding walls. Two or more of the surrounding walls are arranged around the peripheral edge of the back panel. Two or more of the hooks are respectively arranged on the surrounding walls on opposite sides. Each hook includes a horizontal part and a hook part. The hook part extends downward from the horizontal part, and the included angle formed between the hook part and the horizontal part is an obtuse angle. Preferably, the back panel, the enclosure, and the hook are an integral structure.

[0005] Preferably, the cover is a thin steel plate cover, and the hook is a thin steel plate hook.

[0006] Preferably, the cover is a high-strength plastic cover, and the hook is a high-strength plastic hook.

[0007] Preferably, the hook is L-shaped.

[0008] Preferably, the included angle between the hook portion and the horizontal portion is in the range of 91°-95°.

[0009] Preferably, the included angle between the hook portion and the horizontal portion is 94°.

[0010] Preferably, the cover has a square structure, and the hooks are provided with four hooks, which are respectively arranged symmetrically in pairs on the upper and lower parts of the opposite side walls.

[0011] Preferably, a gap is provided between adjacent enclosure walls.

[0012] The wall-mounted protective cover provided by this utility model changes the connection method between the protective cover and the equipment from the traditional bolt connection to an interlocking connection by opening fitting holes in the area where the protective cover needs to be installed. During installation, simply insert the hook part of the hook into the upper part of the fitting hole and press down on the protective cover. The weight of the protective cover will cause the hook part to be tightly fitted into the hole and fixed. During disassembly, there is no need to remove the bolts. It can be removed by gently lifting it upwards, which greatly reduces the difficulty of component assembly and makes on-site equipment maintenance more convenient. At the same time, even without bolt tightening, the structural characteristics of the obtuse angle hook part and the weight of the protective cover can still ensure that the protective cover is stably installed on the equipment. Moreover, the overall connection mechanism is simple, which not only shortens the time required for installation and disassembly and reduces the installation cost for on-site personnel, but also effectively protects the moving parts of the conveying equipment and ensures personnel safety.

[0020] like Figures 1 to 2 As shown, it is a wall-mounted protective cover according to one embodiment of the present utility model.

[0021] Please see Figure 1 and Figure 2 As shown, a wall-mounted protective cover according to an embodiment of the present invention includes a cover body 10 and at least two hooks 20. The cover body 10 includes a back plate 11 and at least two surrounding walls 12. The at least two surrounding walls 12 are arranged around the peripheral edge of the back plate 11. The two or more hooks 20 are respectively arranged on the surrounding walls 12 on opposite sides. The hook 20 includes a horizontal part 21 and a hook part 22. The hook part 22 extends downward from the horizontal part 21, and the included angle formed between the hook part 22 and the horizontal part 21 is an obtuse angle.

[0022] In this embodiment, the cover 10 is a high-strength plastic cover 10 or a thin steel plate cover 10, and the hook 20 is a high-strength plastic hook 20 or a thin steel plate hook 20.

[0023] In this embodiment, the back panel 11, the enclosure 12, and the hook 20 are an integral structure.

[0024] In this embodiment, the hook 20 is L-shaped.

[0025] In this embodiment, the included angle formed between the hook portion 22 and the horizontal portion 21 is defined as... ,but The range is 91°-95°, meaning that the hook part 22 is designed with a small beveled structure.

[0026] Specifically, the included angle between the hook portion 22 and the horizontal portion 21 is 94°.

[0027] In practical applications, such as Figure 3 and Figure 4 As shown, taking a belt conveyor as an example, it mainly includes a frame 100, a conveying platform 101, and moving parts. The conveying platform 101 is mounted on the frame 100. The moving parts generally include a conveyor roller 102 and a tension roller 103, both ends of which are rotatably mounted on the frame 100. The ends of the conveyor roller 102 and the tension roller 103 are usually exposed to the outside environment. To ensure personnel safety, protective covers need to be installed in the concentrated area of ​​the moving parts. The area indicated by the arrow is the concentrated area of ​​the moving parts. Hook holes 104 adapted to the hooks 20 of the wall-mounted protective cover are provided in this concentrated area. The length of the hook holes 104 meets the travel stroke of the hooks 20, and the number of hook holes 104 corresponds to the number of hooks 20.

[0028] When installing the wall-mounted protective cover, insert the hook part 22 into the upper part of the hook hole 104 and press down. Under the action of gravity, the wall-mounted protective cover will automatically move downward along the hook hole 104 until the hook part 22 is pressed tightly against the bottom of the hook hole 104. The angle formed between the hook part 22 and the horizontal part 21 is an obtuse angle. When pressing down on the cover 10, the obtuse angle design ensures that the hook part 22 makes surface contact with the hook hole 104 rather than point contact during its downward movement along the hook hole 104. This increases friction and more stably fixes the cover 10 to the bottom of the hook hole 104, preventing the cover 10 from easily falling off when the equipment vibrates during operation. On the other hand, during installation, it guides the hook part 22 to slide more smoothly into the bottom of the hook hole 104, and under the action of gravity, the hook part 22 will naturally form a tight fit with the bottom of the hook hole 104 without the need for additional fixing operations.

[0029] This embodiment of the wall-mounted protective cover changes the connection method between the protective cover and the equipment from the traditional bolt connection to an interlocking connection by opening fitting holes in the area where the protective cover needs to be installed. During installation, simply insert the hook part 22 of the hook 20 into the upper part of the fitting hole and press down on the protective cover. The weight of the protective cover will cause the hook part 22 to be tightly fitted into the hole and fixed. During disassembly, there is no need to remove the bolts; it can be removed by gently lifting it upwards. This greatly reduces the difficulty of component assembly and makes on-site equipment maintenance more convenient. At the same time, even without bolt tightening, the structural characteristics of the obtuse angle hook part 22 and the weight of the protective cover can still ensure that the protective cover is stably installed on the equipment. Moreover, the overall connection mechanism is simple, which not only shortens the time required for installation and disassembly and reduces the installation cost for on-site personnel, but also effectively protects the moving parts of the conveying equipment and ensures personnel safety.

[0030] Please see Figure 1 and Figure 2 As shown, in some embodiments, exemplarily, the cover 10 has a square structure with four hooks 20, which are symmetrically arranged in pairs on the upper and lower parts of the opposite side walls 12. The four hooks 20 are fixed from the upper and lower parts of the opposite sides of the cover 10, resulting in a more even distribution of stress points after installation. Compared to a smaller number of hooks 20, this effectively avoids excessive local stress caused by concentrated force on the cover 10, thereby reducing the risk of deformation or damage to the cover 10 and greatly improving the overall structural stability, providing more reliable protection for internal moving parts. Furthermore, the upper and lower hooks 20 work together to form a balanced support for the weight of the cover 10 in the vertical direction. Simultaneously, when the equipment vibrates during operation or is subjected to external lateral forces (such as accidental collisions), the symmetrical hooks 20 can better disperse these external forces, preventing the cover 10 from tilting, swaying, or even falling off, ensuring the continuity and effectiveness of the protection.

[0031] It should be noted that the number of hooks 20 is set according to the actual situation and is not limited to four.

[0032] Please see Figure 1 and Figure 2 As shown, in some embodiments, for example, a gap 13 is provided between adjacent enclosure walls 12 to provide a channel for ventilation and heat dissipation inside the equipment during operation, preventing adverse effects on equipment components due to heat accumulation.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
