Technical Field

[0001] The utility model belongs to the technical field of anti-rust installation of bearings, and particularly relates to an anti-rust structure device for bearings. Background Art

[0002] A security camera is a collection device that takes security and prevention video monitoring as the purpose and converts the optical image in the range from visible light to near-infrared spectrum on the target surface of the image sensor into a video image signal. During the assembly process of the sphere and the bracket of the security camera, bearings are installed at the connection parts on both sides of the two to meet the smoothness of the sphere during rotation in the use process of the security camera, so as to monitor the picture in real time.

[0003] In the existing security cameras, the installed bearings are not made of stainless steel. And some installation scenarios of security cameras are in places with sunlight exposure, rain, and high acidity and alkalinity. Due to a gap of about mm at the bearing installation position, this causes water vapor and dust to directly enter the bearing position. And since the bearing is made of iron, after long-term use, rust appears on the bearing, and in severe cases, the sphere cannot move up and down normally, thus affecting the normal use of the camera. For this reason, the utility model proposes an anti-rust structure device for bearings. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an anti-rust structure device for bearings to solve the problem of rusting that occurs after long-term use due to the non-stainless-steel structure of the bearings installed in the security cameras as mentioned in the above background art.

The two sides of the sphere are in a clamped state with the two sides of the bracket. Bearing bodies are sleeved on the two sides of the sphere where the two sides of the sphere are clamped with the two sides of the bracket and on the two side surfaces of the sphere. An anti-rust mechanism is arranged at the connection part between the two ends of the sphere and the inner side of the bracket. The anti-rust mechanism is composed of lubricating oil and a plastic cover sheet. The plastic cover sheet is sleeved on the side surface of the sphere and on the side of the bearing body. The lubricating oil is filled in the gaps among the plastic cover sheet, the bearing body, and the side surface of the sphere.

[0006] Preferably, the plastic cover sheet is composed of block A and block B, and block B is fixed to the outside of block A.

[0007] Preferably, the cross-section of the plastic cover sheet is in a circular structure.

[0008] Preferably, a sealing gasket is arranged between the side surface of the sphere and the inner side of the bracket, and the sealing gasket is sleeved on the side surface of the sphere.

[0010] Preferably, the inner diameter of the PVC backing plate is the same as that of the silica gel seat, and the cross-section of the silica gel seat is a circular structure.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] Through the designed anti-rust mechanism, the problem that the bearings installed in the original security camera are not made of stainless steel and rust after long-term use, affecting the normal use of the camera, is improved. The anti-rust mechanism is used to separate the bearing body from external aerosols and dust, ensuring the durability of the bearing body and increasing the service life of the camera, so as to meet the design service life of the camera in different scenarios. Without replacing the stainless steel bearings, the effect of cost reduction is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a bearing anti-rust structure device, which includes a bracket 3 arranged inside the mounting frame 1 and a sphere 2 arranged inside the mounting frame 1. The two sides of the sphere 2 and the two sides of the bracket 3 are in a clamped state. Bearing bodies 4 are sleeved on the surfaces of the two sides of the sphere 2 where they are clamped with the two sides of the bracket 3. By providing the bearing bodies 4, the sphere 2 can rotate smoothly to monitor the real-time picture. Anti-rust mechanisms 5 are arranged at the connecting parts between the two ends of the sphere 2 and the inner side of the bracket 3. The anti-rust mechanisms 5 are composed of lubricating oil 51 and plastic cover sheets 52. The plastic cover sheets 52 are sleeved on the side surface of the sphere 2 and are located on the side of the bearing bodies 4. The lubricating oil 51 is filled in the gaps among the plastic cover sheets 52, the bearing bodies 4, and the side surface of the sphere 2. Through the designed anti-rust mechanisms 5, the problem that the bearings installed in the original security cameras are not made of stainless steel and rust after long-term use, affecting the normal use of the cameras, is improved. Through the anti-rust mechanisms 5, the bearing bodies 4 are separated from external aerosols and dust, ensuring the durability of the bearing bodies 4 and increasing the service life of the cameras, so as to meet the design service life of the cameras in different scenarios. Without replacing the stainless steel bearings, the effect of cost reduction is achieved. The plastic cover sheets 52 are composed of block A 521 and block B 522. Block B 522 is fixed to the outside of block A 521. The cross-section of the plastic cover sheets 52 is in a circular structure. A sealing gasket 6 is arranged between the side surface of the sphere 2 and the inner side of the bracket 3, and the sealing gasket 6 is sleeved on the side surface of the sphere 2.

[0019] In this embodiment, preferably, the sealing gasket 6 is composed of a PVC backing plate 61 and a silicone seat 62. The PVC backing plate 61 is fixed to the surface of the silicone seat 62. The silicone seat 62 is fixed to the inner side of the bracket 3. The inner diameter size of the PVC backing plate 61 is the same as the inner diameter size of the silicone seat 62. The cross-section of the silicone seat 62 is in a circular structure. Without affecting the normal use, the sealing gasket 6 increases the sealing performance at the joint between the sphere 2 and the bracket 3, further ensuring the service life of the bracket 3 and thus not affecting the normal use of the security camera.

[0020] The working principle and usage process of the present utility model: During the assembly of the security camera, first, the sphere 2 is initially clamped into the inner side of the bracket 3, then the plastic cover sheets 52 are sleeved on the protruding parts on the side surface of the sphere 2, and the lubricating oil 51 is squeezed in to fill the gaps between the plastic cover sheets and the bracket. Then the bearing bodies 4 are sleeved in and the cover sheets are pressed tightly, so that the 0.1 mm gap between the cover sheets and the bracket is filled with the lubricating oil. The viscosity of the lubricating oil itself does not affect the rotation of the plastic cover sheets and the bearings. The water vapor and dust are separated by the lubricating oil, thus protecting the bearings from rusting.

[0021] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
