Description

Technical Field

[0001] The utility model belongs to the technical field of mesh dust cover, and in particular relates to a mesh dust cover. Background Art

[0002] When high-precision equipment is used in harsh environments, the spare network ports are prone to dust and other substances. Due to the influence of dust and other substances, when the network port is enabled, it is easy to cause unstable data transmission, which reduces the service life of the equipment. When traditional dust covers are applied to network ports, they are generally embedded in the mesh by interference fit. Due to the special shape of the network port, it is difficult to embed the blocking part into the mesh. For example, if the blocking part of the dust cover is made the same size as the network port, it is convenient to block, but it is easy to detach when used in harsh environments, such as when used on mobile devices. In order to solve the above problems, our company has designed and proposed a mesh dust cover. Utility Model Content

[0003] The utility model aims to solve the problem that the dust cover in the prior art is not easy to block, and proposes a mesh dust cover. The mesh dust cover can effectively protect the network port, improve the stability of data transmission, and increase the service life of the equipment.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] The structural features of the utility model are now described in detail with reference to the accompanying drawings of the specification.

[0021] See also Figure 1-Figure 2A mesh dust cover includes a cover plate 1. The cover plate 1 is a hard cover plate, such as a plastic material. A connection portion 2 is provided at one end of the cover plate 1. A rotating shaft 3 is fixed at the end of the connection portion 2. The rotating shaft 3 is rotatably connected to the device. A limiting ring 4 is provided on the rotating shaft 3. The limiting ring 4 can prevent the cover plate 1 from falling off the device. A buckle groove 11 is provided at one end of the cover plate 1 away from the connection portion 2 and located on one side of the blocking block 5. The buckle groove 11 facilitates the cover plate 1 to be picked up from the device. A blocking block 5 with a flexible structure adapted to the size of the mesh is provided on one side of the rotating shaft 3 of the cover plate 1. A cavity 51 is provided inside the blocking block 5. The cavity 51 is provided with a support and limiting mechanism 6 for expanding the outer diameter of the blocking block 5. The support and limit mechanism 6 includes a push-pull rod 61, which is arranged on the cover plate 1, and a support block 62 is arranged at one end of the push-pull rod 61 located inside the cavity 51. A boss 63 of an annular structure is arranged inside the end of the cavity 51, and an expansion opening 64 is formed inside the boss 63. The inner diameter of the expansion opening 64 is smaller than the outer diameter of the support block 62. In order to smoothly insert the support block 62 into the expansion opening 64, the transverse base surface of the support block 62 is a conical structure, and an inner chamfer is arranged on one side of the expansion opening 64 corresponding to the support block 62. During specific use, the blocking block 5 is inserted into the mesh. Since the blocking block 5 is the same size as the mesh, it is easy to insert the blocking block 5 into the mesh. Then, the push-pull rod 61 is pressed downward to insert the support block 62 into the expansion port 64. Due to the insertion of the support block 62, the boss 63 is squeezed outward, so that the outer diameter of the blocking block 5 increases. The enlarged blocking block 5 is embedded in the mesh in an interference fit manner. On the one hand, the blocking block 5 is more tightly sealed in the mesh, thereby improving the sealing and dustproof effects. On the other hand, it is fixed in the network in an interference fit manner, so that it is not easy to fall off and the blocking is more stable.

[0022] Example 2

[0023] Reference Figure 3 As another preferred embodiment of the utility model, the difference from the embodiment 1 is that the support and limit mechanism 6 includes a push-pull rod 61, which is set on the cover plate 1, and the push-pull rod 61 is rotatably connected to elastic sheets 66 on both sides of one end of the push-pull rod 61 located inside the cavity 51, and the other end of the elastic sheet 66 is rotatably connected to a rotating seat 65, which is fixedly set on the side wall of the cavity 51. Specifically, when in use, the blocking block 5 is inserted into the mesh, and then the push-pull rod 61 is pressed down, so that the push-pull rod 61 pushes and opens the elastic sheet 66, so that the elastic sheet 66 is pushed from the original inclined state to the horizontal state, and under the support of the rotating seat 65, the outer diameters of both sides of the blocking block 5 are increased, and the enlarged blocking block 5 is embedded in the mesh in an interference fit manner, which, on the one hand, makes the blocking block 5 more tightly blocked in the mesh, improves the sealing and dustproof effects, and on the other hand, is fixed in the mesh in an interference fit manner, so that it is not easy to fall, and the blocking is more stable.

[0024] The mesh dust cover of the utility model has a simple structure and is easy to install. A sealing block 5 with a flexible structure that is compatible with the size of the mesh is arranged on the cover plate 1, and a cavity 51 is arranged inside the sealing block 5, so that the sealing block 5 can be easily inserted into the mesh, which is convenient for the sealing installation of the sealing block 5 on the mesh. A supporting and limiting mechanism 6 that can expand the outer diameter of the sealing block 5 is arranged in the cavity 51, so that the sealing block 5 installed in the mesh can expand outward to increase the outer diameter, so that the sealing block 5 is interference fit in the mesh, so that the sealing block 5 is not easy to detach from the mesh, and the stability of the sealing is improved, thereby providing good protection for the mesh and effectively solving the problem of unstable data transmission caused by dust and the like entering the mesh in harsh environments.
