Description
Technical Field
[0001] This utility model relates to the field of adsorption equipment technology, specifically to an adsorption structure and its projector lens cover. Background Technology
[0002] Projector lens caps are important accessories used to protect projector lenses. They can effectively prevent dust, fingerprints, scratches and other damage to the lens, extend the lens's lifespan, and maintain the clarity and quality of the projected image.
[0003] According to Chinese Patent Publication No. CN217587846U, a projector with a magnetic lens cover is disclosed, including a working mechanism and a replacement mechanism. A cover-closing mechanism for protection is installed on the front surface of the working mechanism, and a replacement mechanism for quick replacement is located in the middle of one side surface of the working mechanism. A recycling mechanism for safe storage is provided on the lower surface of the working mechanism. Compared with existing devices, this projector with a magnetic lens cover allows the PU protective cover to be folded and rotated via a folding edge. When the device is idle, the magnetic strip allows it to be attached and fixed to the left side of the projector's illumination area, thus protecting the illumination area from dust and moisture, preventing contamination and damage, and avoiding cleaning problems. Simultaneously, when the projector is working, the PU protective cover can be attracted to the right side, thus not affecting normal projection. An auxiliary block facilitates opening and closing the PU protective cover.
[0004] However, the current adsorption structure and its projector lens cover have the following problems: they are not easy to quickly adsorb and fix, and the traditional magnetic structure is prone to falling off, so improvements are needed. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adsorption structure and a projector lens cover thereof, comprising a mating groove, a first magnetic block, a housing, a lens and an adsorption structure, wherein the housing is magnetically connected to the lens via the magnetic block, the first magnetic block is fixedly provided on the housing, and a mating groove is provided inside the housing, and an adsorption structure is provided at the front end of the lens.
[0007] The adsorption structure is used to protect the lens. The arc-shaped bracket can be inserted into the mating groove, and the rotation can control the magnetic attraction and fixation of the second magnetic block and the first magnetic block, thereby limiting and fixing the mating groove, the first magnetic block, the housing, the lens, and the adsorption structure.
[0008] Specifically, the adsorption structure includes a docking shaft, an arc-shaped frame, a plug-in block, a lens cap, and a second magnetic block. The rear end of the lens cap is fixedly connected to the plug-in block, and the plug-in block is fixedly connected to the second magnetic block.
[0009] Specifically, the rear end of the plug block is fixedly connected to a docking shaft, and the lower end of the docking shaft is fixedly connected to an arc-shaped frame.
[0010] Specifically, the mating groove is interference-fitted with the arc-shaped frame.
[0011] Specifically, the lower end of the plug-in block is arc-shaped and can move at the position of the longitudinal groove on the casing.
[0012] Specifically, the projector lens cover adopts a combination of a mating groove, a first magnetic block, a housing, a lens, and an adsorption structure. The lens is installed on the projector, and the projector is also equipped with a heat dissipation groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] By installing an adsorption structure, a docking shaft, an arc-shaped bracket, a plug-in block, and a second magnetic block are set on the lens cap inside the adsorption structure. The docking shaft, arc-shaped bracket, plug-in block, and second magnetic block are fixed to the lens cap. The docking shaft, arc-shaped bracket, plug-in block, and second magnetic block can be inserted into the longitudinal groove on the housing. Then, the lens cap is screwed on, which drives the docking shaft, arc-shaped bracket, plug-in block, and second magnetic block to rotate, so that the arc-shaped bracket enters the interior of the mating groove for interference fit and limiting. At the same time, the second magnetic block contacts the first magnetic block for magnetic attraction and limiting. The adsorption structure can be screwed on both ends, and adsorption processing can be performed in both directions. Attached Figure Description

[0020] Please see Figure 1-3 This utility model provides a technical solution: an adsorption structure and its projector lens cover, including a mating groove 1, a first magnetic block 2, a housing 3, a lens 4, and an adsorption structure 5. The housing 3 is magnetically connected to the lens 4 via the magnetic block. The first magnetic block 2 is fixedly mounted on the housing 3, and the mating groove 1 is provided inside the housing 3. The adsorption structure 5 is provided at the front end of the lens 4. By installing the adsorption structure 5, a docking shaft 6, an arc-shaped bracket 7, a plug-in block 8, and a second magnetic block 10 are provided on the lens cover 9 inside the adsorption structure 5. 7. The insertion block 8, the second magnetic block 10 and the lens cap 9 are fixed together, so that the docking shaft 6, the arc frame 7, the insertion block 8 and the second magnetic block 10 can be inserted into the longitudinal groove on the housing 3. Then, the lens cap 9 is screwed on, which drives the docking shaft 6, the arc frame 7, the insertion block 8 and the second magnetic block 10 to rotate, so that the arc frame 7 enters the interior of the mating groove 1 and is limited by interference fit. At the same time, the second magnetic block 10 contacts the first magnetic block 2 for magnetic attraction and limitation. The adsorption structure 5 can be screwed on both ends, and can be used for adsorption processing.
[0021] The adsorption structure 5 is used to protect the lens 4. The arc-shaped bracket 7 can be inserted into the mating groove 1, and the rotation can control the second magnetic block 10 to be magnetically fixed with the first magnetic block 2, so as to limit and fix the mating groove 1, the first magnetic block 2, the housing 3, the lens 4 and the adsorption structure 5.
[0022] The adsorption structure 5 includes a docking shaft 6, an arc-shaped frame 7, a plug-in block 8, a lens cap 9, and a second magnetic block 10. The rear end of the lens cap 9 is fixedly connected to the plug-in block 8, and the second magnetic block 10 is fixedly connected to the plug-in block 8. The adsorption structure 5 is placed on the lens 4 of the projector 11 to facilitate the protection of the lens 4. The projector 11 is also equipped with a heat dissipation groove 12 for heat dissipation. The lens 4 is fixed to the projector 11. The user pre-installs the first magnetic block 2 and the housing 3 on the lens 4, and the lens 4 is held in place by magnetic attraction. The limiting connection is established, and the rear end of the housing 3 is fixed to the projector 11 by adhesive bonding. The user inserts the adsorption structure 5 into the longitudinal groove of the housing 3. At this time, the docking shaft 6, the arc frame 7, the plug block 8, and the second magnetic block 10 reach the bottom of the housing 3. When the lens cover 9 is rotated, the docking shaft 6, the arc frame 7, the plug block 8, and the second magnetic block 10 rotate accordingly. At this time, the arc frame 7 is interference-fitted with the mating groove 1, and the first magnetic block 2 is adsorbed and fixed with the second magnetic block 10 on one side, so that the lens 4 and the lens cover 9 can be connected.
[0023] The rear end of the plug block 8 is fixedly connected to the docking shaft 6, and the lower end of the docking shaft 6 is fixedly connected to the arc-shaped frame 7.
[0024] The mating groove 1 is interference-fitted with the arc-shaped frame 7.
[0025] The lower end of the plug-in block 8 is arc-shaped and can move at the position of the longitudinal groove on the housing 3.
[0026] The projector lens cover is composed of a mating groove 1, a first magnetic block 2, a housing 3, a lens 4, and an adsorption structure 5. The lens 4 is installed on the projector 11, and the projector 11 is also provided with a heat dissipation groove 12.
[0027] Working principle: When needed, the user places the adsorption structure 5 on the lens 4 of the projector 11 for easy protection of the lens 4. The projector 11 is also equipped with a heat dissipation groove 12 for heat dissipation. The lens 4 is fixed to the projector 11. The user first installs the first magnetic block 2 and the housing 3 on the lens 4, and the connection is limited by magnetic attraction. The rear end of the housing 3 is fixed to the projector 11 by adhesive bonding. The user inserts the adsorption structure 5 into the longitudinal groove of the housing 3. At this time, the docking shaft 6, the arc frame 7, the plug block 8, and the second magnetic block 10 reach the bottom of the housing 3. Rotating the lens cover 9 causes the docking shaft 6, the arc frame 7, the plug block 8, and the second magnetic block 10 to rotate as well. At this time, the arc frame 7 is interference-fitted with the mating groove 1, and the first magnetic block 2 is adsorbed and fixed with the second magnetic block 10 on one side. The lens 4 and the lens cover 9 can then be connected to complete the work.
