Description

Technical Field

[0001] This application relates to the field of face mask technology, and more particularly to a cover plate mounting structure. Background Technology

[0002] Protective face shields are designed to prevent chips, hard sand particles, and other debris from entering the housing, reducing damage to the equipment inside the housing caused by hard particulate matter. They can also reduce the impact of damage to various components of the equipment inside the housing, maintaining safety. The surface of the protective face shield should be smooth and free of burrs and sharp edges, and should not become a new source of danger.

[0003] Assembly, also known as the final stage of the entire mechanical manufacturing process, is the process of combining several parts into components or parts, or assembling components or parts of several parts into a product, according to specified technical requirements.

[0004] After the equipment is assembled with its shell and internal components, a face shield is needed to seal the equipment, completing the outer packaging process. However, the face shield of an existing device is connected by three connecting posts on the front. In actual installation, due to the need for stability, the insertion posts are quite deep. Direct insertion can easily cause the insertion posts to tilt or break, making it inconvenient to use.

[0005] Therefore, this application proposes a cover plate mounting structure. Utility Model Content

[0006] This application proposes a cover plate installation structure to solve the problems mentioned in the background art. When the connecting post and the hole-type connecting groove are inserted, the mask and the shell can be initially connected by the oblique insertion mechanism to provide an accurate installation position for subsequent insertion. Then, by setting the docking mechanism on both sides of the mask, the tilting and breakage of the connecting post and the hole-type connecting groove can be effectively prevented, thereby improving the installation efficiency and installation effect, reducing the loss caused by improper installation, and thus reducing wear and tear.

[0007] To achieve the above objectives, this application adopts the following technical solution:

[0008] A cover plate mounting structure includes a face mask, a housing, a straight insertion mechanism, an oblique insertion mechanism, and a docking mechanism. The face mask and the housing are assembled together. A straight insertion mechanism is provided between the face mask and the housing. The straight insertion mechanism includes a set of connecting posts and a hole-shaped connecting groove. There are three connecting posts, each of which is fixedly connected to the inner side of the face mask. There are three hole-shaped connecting grooves arranged opposite each other, each of which is fixedly connected to the inner side of the housing. The end of each connecting post away from the face mask extends into the hole-shaped connecting groove.

[0009] In a preferred embodiment, two sets of oblique insertion mechanisms are provided between the mask and the housing, each set of oblique insertion mechanisms including an oblique groove and an L-shaped connecting block;

[0010] By setting up an oblique insertion mechanism, the housing can be inserted obliquely into the mask first. After the housing is inserted, it can be laid flat to complete the assembly of the mask, thereby improving the practicality of the device.

[0011] In a preferred embodiment, both of the inclined slots are formed inside the face mask, and the housing is fixedly connected to the mounting surface of the face mask by two L-shaped connecting blocks;

[0012] By aligning the L-shaped connecting block on the inclined insertion mechanism housing with the inclined groove on the mask, the L-shaped connecting block is inserted into the inclined groove, thereby improving the practicality of the device.

[0013] In a preferred embodiment, the housing is assembled with the mask by inserting an L-shaped connecting block into the inclined groove;

[0014] By setting up an oblique insertion mechanism, when the L-shaped connecting block extends into the oblique groove, the housing and the mask are successfully inserted at an oblique angle, thereby improving the practicality of the device.

[0015] In a preferred embodiment, two sets of docking mechanisms are provided between the mask and the shell, each set of docking mechanisms including a docking block and a docking groove;

[0016] By setting up a docking mechanism, after the shell is inserted at an angle, the shell is rotated toward the face mask. During the rotation, the docking block will extend into the docking groove from one end of the angled insertion mechanism, thereby improving the practicality of the device.

[0017] In a preferred embodiment, both of the mating blocks are fixedly connected to the inside of the face mask, and two mating grooves are provided on the mounting surface of the housing and the face mask;

[0018] By setting up a docking mechanism, as the housing continues to rotate toward the mask, the docking block will slowly extend completely into the docking groove, thereby improving the practicality of the device.

[0019] In a preferred embodiment, both of the mating blocks have arc-shaped side insertion surfaces, and both of the mating slots have semi-circular insertion interfaces.

[0020] By setting an arc shape on the insertion surface of the docking block and a semi-circular shape on the insertion interface of the docking groove, the docking block can be docked more smoothly, thereby improving the practicality of the device.

[0021] In a preferred embodiment, both of the docking blocks are inserted into the docking groove in an arc shape and a semi-arc shape, and the mask is assembled with the shell through the docking blocks and the docking groove;

[0022] The use of arcs and semi-circles, compared to the ordinary flat type, makes the insertion smoother, thus improving the insertion efficiency. At the same time, it prevents damage to the cover and housing caused by tilting during insertion, thereby improving the practicality of the device.

[0023] The beneficial effects of this application are:

[0024] 1. This cover plate installation structure, when the connecting column and the hole-type connecting groove are inserted, firstly, the oblique insertion mechanism can be used to make a preliminary connection between the mask and the housing, providing an accurate installation position for subsequent insertion. Then, by setting docking mechanisms on both sides of the mask, it can effectively prevent tilting or breakage when the connecting column and the hole-type connecting groove are inserted, thereby improving installation efficiency and installation effect, reducing losses caused by improper installation, and thus reducing wear and tear, greatly improving the practicality of the device;

[0025] 2. This cover plate installation structure, through the setting of an oblique insertion mechanism, allows the housing to be inserted obliquely into the face mask first. During the insertion of the housing, the L-shaped connecting block on the housing aligns with the oblique groove on the face mask, allowing the L-shaped connecting block to be inserted into the oblique groove. As the L-shaped connecting block continues to extend into the oblique groove, the oblique insertion between the housing and the face mask is successful. Then, through the setting of a docking mechanism, after the oblique insertion of the housing is completed, the housing is rotated towards the face mask. During the rotation, the end of the docking block away from the oblique insertion mechanism will first extend into the docking groove. As the housing continues to rotate towards the face mask, the docking block will slowly extend completely into the docking groove. By setting an arc shape on the insertion surface of the docking block and a semi-circular shape on the insertion interface of the docking groove, the docking block can be made smoother during the docking process. Compared with the ordinary flat type, the insertion is smoother, thus improving the insertion efficiency. At the same time, it prevents damage to the face mask and housing caused by the tilting of the insertion, greatly improving the practicality of the device. Attached Figure Description

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0033] Reference Figure 1-5 A cover plate mounting structure includes a face mask 1, a housing 2, a straight insertion mechanism 3, an oblique insertion mechanism 4, and a docking mechanism 5. The face mask 1 and the housing 2 are assembled together. A straight insertion mechanism 3 is provided between the face mask 1 and the housing 2. The straight insertion mechanism 3 includes a set of connecting posts 31 and a hole-shaped connecting groove 32. There are three connecting posts 31, each of which is fixedly connected to the inside of the face mask 1. There are three hole-shaped connecting grooves 32, each of which is fixedly connected to the inside of the housing 2. The end of each connecting post 31 away from the face mask 1 extends into the hole-shaped connecting groove 32.

[0034] Reference Figure 1-5 Two sets of oblique insertion mechanisms 4 are provided between the mask 1 and the housing 2. Each set of oblique insertion mechanisms 4 includes an oblique groove 41 and an L-shaped connecting block 42. By setting the oblique insertion mechanism 4, the housing 2 can be inserted obliquely into the mask 1 first. After the housing 2 is inserted, it can be laid flat to complete the assembly of the mask, thereby improving the practicality of the device.

[0035] Reference Figure 1-5 Both inclined slots 41 are opened inside the mask 1. The housing 2 and the mounting surface of the mask 1 are fixedly connected to two L-shaped connecting blocks 42. By setting the inclined insertion mechanism 4, the L-shaped connecting blocks 42 on the housing 2 are aligned with the inclined slots 41 on the mask 1, so that the L-shaped connecting blocks 42 are inserted into the inclined slots 41, thereby improving the practicality of the device.

[0036] Reference Figure 1-5 The housing 2 is assembled with the mask 1 by inserting the L-shaped connecting block 42 into the inclined groove 41; by setting the inclined insertion mechanism 4, when the L-shaped connecting block 42 continues to extend into the inclined groove 41, the housing 2 and the mask 1 are successfully inserted at an angle, thereby improving the practicality of the device.

[0037] Reference Figure 1-5Two sets of docking mechanisms 5 are provided between the mask 1 and the housing 2. Each set of docking mechanisms 5 includes a docking block 51 and a docking groove 52. By setting the docking mechanism 5, after the housing 2 is inserted at an angle, the housing 2 is rotated toward the mask 1. During the rotation, the end of the docking block 51 that is away from the angled insertion mechanism 4 will first extend into the docking groove 52, thereby improving the practicality of the device.

[0038] Reference Figure 1-5 Both docking blocks 51 are fixedly connected to the inside of the mask 1. The mounting surfaces of the housing 2 and the mask 1 have two docking grooves 52. By setting the docking mechanism 5, when the housing 2 continues to rotate towards the mask 1, the docking blocks 51 will slowly extend into the docking grooves 52, thereby improving the practicality of the device.

[0039] Reference Figure 4-5 Both mating blocks 51 have arc-shaped surfaces 511 on their sides, and both mating slots 52 have semi-circular surfaces 521 on their insertion interfaces. By setting arc-shaped surfaces 511 on the mating blocks 51 and semi-circular surfaces 521 on the insertion interfaces of the mating slots 52, the mating blocks 51 can be mated more smoothly, thereby improving the practicality of the device.

[0040] Reference Figure 1-5 Both docking blocks 51 are inserted into the docking groove 52 through arc 511 and semi-arc 521, and the mask 1 is assembled with the housing 2 through the docking blocks 51 and docking groove 52. The arc 511 and semi-arc 521, compared with the ordinary flat type, make the insertion smoother, thus improving the insertion efficiency. At the same time, it prevents the insertion tilt from causing damage to the mask 1 and the housing 2, thereby improving the practicality of the device.

[0041] Working principle: The face mask 1 is made of plastic shell. The waterproof performance of plastic mainly benefits from its seamless sealing. During the processing, plastic can be made into a seamless molded object, which makes its waterproof performance even better. In addition, plastic material has excellent corrosion resistance and will not be corroded by water, oil, acids, alkalis, etc., further enhancing its waterproof performance. When installing the face mask 1 and the shell 2, by setting up the oblique insertion mechanism 4, the shell 2 can be inserted obliquely into the face mask 1 first. When the shell 2 is inserted, the L-shaped connecting block 42 on the shell 2 aligns with the oblique groove 41 on the face mask 1, so that the L-shaped connecting block... 42 is inserted into the inclined groove 41. When the L-shaped connecting block 42 continues to extend into the inclined groove 41, the inclined insertion between the housing 2 and the mask 1 is successful. Then, by setting the docking mechanism 5, after the inclined insertion of the housing 2 is completed, the housing 2 is rotated towards the mask 1. During the rotation, the end of the docking block 51 that is away from the inclined insertion mechanism 4 will first extend into the docking groove 52. When the housing 2 continues to rotate towards the mask 1, the docking block 51 will slowly extend completely into the docking groove 52. By setting an arc-shaped 511 on the insertion surface of the docking block 51 and setting on the insertion interface of the docking groove 52, The semi-circular angle 521 allows the mating block 51 to move more smoothly during the mating process, compared to a conventional flat type. This makes the insertion smoother, thus improving the insertion efficiency. It also prevents damage to the face shield 1 and housing 2 caused by tilting during insertion. When the mating block 51 is almost fully inserted near the end of the direct insertion mechanism 3, the hole-shaped connecting groove 32 on the housing 2 will mate with the connecting post 31 on the face shield 1 through the direct insertion mechanism 3. As the housing 2 continues to rotate, the connecting post 31 will slowly extend into the hole-shaped connecting groove 32. When the assembly surfaces of the housing 2 and the face shield 1 are fully connected... When the contact is made, the connecting post 31 will be fully inserted into the hole-type connecting groove 32, so that the installation between the mask 1 and the housing 2 is completed. When the connecting post 31 and the hole-type connecting groove 32 are inserted, the oblique insertion mechanism 4 can first make a preliminary connection between the mask 1 and the housing 2, providing an accurate installation position for subsequent insertion. Then, by setting the docking mechanism 5 on both sides of the mask 1, the tilting or breakage of the connecting post 31 and the hole-type connecting groove 32 during insertion can be effectively prevented, thereby improving the installation efficiency and installation effect, reducing the loss caused by improper installation, and thus reducing wear and tear.
