Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning component technology, specifically to an anti-detachment pressure plate for automotive air conditioning. Background Technology

[0002] In daily life, when we need to replace the car filter, we often need to use a pressure plate to fix and limit the car filter to prevent it from falling off. However, the existing air conditioning anti-detachment pressure plates are difficult to install and remove, which can lead to damage to the cover. Most of them rely on the interlocking of plastic clips without a secondary locking mechanism. Long-term vehicle vibration may cause the clips to fatigue and deform, causing the cover to loosen, resulting in filter displacement or dust ingress. At the same time, when removing the cover, tools are often needed. Improper removal can also cause the clips to deform, leading to damage to the cover. Utility Model Content

[0003] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a quick-install water-sealed filter drain assembly, comprising: a housing, a fixing device provided on the outer wall of the housing, and a self-locking device provided on the outer wall of the housing; the fixing device includes a collar, a telescopic rod fixedly connected to the inner wall of the collar, a fixing ring slidably connected to the outer wall of the telescopic rod, a cover plate fixedly connected to the outer wall of the fixing ring, a baffle fixedly connected to the outer wall of the fixing ring, and a toothed plate slidably connected to the inner wall of the baffle.

[0004] Preferably, a compression spring is fixedly connected to the outer wall of the collar, a limiting plate is slidably connected to the outer wall of the telescopic rod, and a tension spring is fixedly connected to the inner wall of the cover plate. A convex plate is fixedly connected to the end of the tension spring away from the cover plate. When installing the car air conditioning cover plate, first, the car air conditioning filter element is placed into the housing. Then, the handle is pulled, and the sleeve is pulled out under the action of the handle. Then, the sleeve is rotated, so that the sleeve is locked by the square frame, which compresses the limiting spring. The locking plate rotates around the rotating rod, and the gear locking is completed. Then, the cover plate is aligned with the housing and pressed down, so that the telescopic rod slides in the fixing ring under the pressure of the limiting plate. At this time, the compression spring is compressed by the collar until the telescopic rod is locked in the limiting plate. At this time, the cover plate is fixed. Then, the sleeve is rotated again to release the fixation between the sleeve and the square frame. At this time, the locking plate is pressed by the limiting spring, so that the locking plate and the gear mesh with each other, fixing the gear to prevent the cover plate from loosening when the car is moving.

[0005] Preferably, the outer wall of the limiting plate is fixedly connected to the outer wall of the outer shell, the end of the compression spring away from the collar is slidably connected to the outer wall of the telescopic rod, the outer wall of the convex plate is slidably connected to the inner wall of the cover plate, the outer wall of the cover plate is slidably connected to the outer wall of the outer shell, and the outer wall of the toothed plate is fixedly connected to the outer wall of the collar.

[0006] Preferably, the self-locking device includes a square frame, a sleeve slidably connected to the inner wall of the square frame, a handle slidably connected to the inner wall of the sleeve, a locking plate fixedly connected to the end of the handle away from the square frame, a rotating rod rotatably connected to the inner wall of the locking plate, a limit spring fixedly connected to the outer wall of the locking plate, and a gear slidably connected to the end of the locking plate away from the rotating rod.

[0007] Preferably, the end of the limiting spring away from the clamping plate is fixedly connected to the inner wall of the square frame, the outer wall of the rotating rod is fixedly connected to the outer wall of the cover plate, the outer wall of the toothed plate is symmetrically meshed with the outer wall of the gear, and the outer wall of the gear is rotatably connected to the outer wall of the cover plate. When we need to replace the car air conditioning filter, we pull the handle, and the sleeve is pulled out under the action of the handle. At this time, we rotate the sleeve so that the sleeve is clamped by the square frame, and rotate the gear. The gear and the toothed plate that meshes with it symmetrically move. While the toothed plate moves in the baffle, it drives the telescopic rod to move until the telescopic rod is completely disengaged from the limiting plate. At this time, the cover plate is removed to replace the car air conditioning filter.

[0008] The beneficial effects of this utility model are as follows:

[0009] 1. This utility model, by setting a fixing device, provides good mechanical fixation when the telescopic rod is inserted into the limiting plate, while the engagement of the locking plate and the gear provides additional locking force. This dual fixing mechanism improves the reliability and safety of the cover plate fixing. By pulling the handle and rotating the sleeve at the same time, the locking plate can be temporarily released from the gear, allowing the cover plate to be smoothly pressed into place, avoiding interference from the locking mechanism during installation. After installation, simply rotate the sleeve again to automatically restore the locking state, preventing the cover plate from loosening during movement.

[0010] 2. This utility model incorporates a self-locking device. By pulling the handle and rotating the sleeve, the gear is stopped. At this point, the gear rotates and meshes with the toothed plate, converting the rotational force into a linear tension. This ensures that the telescopic rod smoothly disengages from the limiting plate, allowing the cover plate to be removed. This prevents damage to parts caused by violent disassembly.

[0020] Example:

[0021] Please see Figure 1 - Figure 7 This utility model provides a technical solution comprising: a housing 1, a fixing device 2 and a self-locking device 3 on the outer wall of the housing 1; the fixing device 2 includes a collar 26, a telescopic rod 21 fixedly connected to the inner wall of the collar 26, a fixing ring 27 slidably connected to the outer wall of the telescopic rod 21, a cover plate 24 fixedly connected to the outer wall of the fixing ring 27, a baffle 22 fixedly connected to the outer wall of the fixing ring 27, and a toothed plate 23 slidably connected to the inner wall of the baffle 22. When the car air conditioning filter is placed into the housing 1, the handle 32 is pulled, and the sleeve 31 is pulled out under the action of the handle 32. The sleeve 31 is then rotated, causing the sleeve 31 to be locked by the square frame 33, which compresses the limiting spring 36. The locking plate 34 rotates around the rotating rod 35, and the locking of the gear 37 ends.

[0022] A compression spring 25 is fixedly connected to the outer wall of the collar 26, a limiting plate 20 is slidably connected to the outer wall of the telescopic rod 21, and a tension spring 242 is fixedly connected to the inner wall of the cover plate 24. A convex plate 241 is fixedly connected to the end of the tension spring 242 away from the cover plate 24. When the cover plate 24 is aligned with the outer shell 1 and pressed, the telescopic rod 21 slides in the fixing ring 27 under the pressure of the limiting plate 20. At this time, the compression spring 25 is compressed by the collar 26 until the telescopic rod 21 is inserted into the limiting plate 20. At this time, the cover plate 24 is fixed. Rotate the sleeve 31 again to release the fixation between the sleeve 31 and the square frame 33. At this time, the locking plate 34 is pressed by the limiting spring 36, so that the locking plate 34 and the gear 37 mesh with each other and fix the gear 37 to prevent the cover plate 24 from loosening when the car is moving.

[0023] The outer wall of the limiting plate 20 is fixedly connected to the outer wall of the outer shell 1. The end of the compression spring 25 away from the collar 26 is slidably connected to the outer wall of the telescopic rod 21. The outer wall of the convex plate 241 is slidably connected to the inner wall of the cover plate 24. The outer wall of the cover plate 24 is slidably connected to the outer wall of the outer shell 1. The outer wall of the toothed plate 23 is fixedly connected to the outer wall of the collar 26.

[0024] The self-locking device 3 includes a square frame 33. A sleeve 31 is slidably connected to the inner wall of the square frame 33. A handle 32 is slidably connected to the inner wall of the sleeve 31. A locking plate 34 is fixedly connected to the end of the handle 32 away from the square frame 33. A rotating rod 35 is rotatably connected to the inner wall of the locking plate 34. A limit spring 36 is fixedly connected to the outer wall of the locking plate 34. A gear 37 is slidably connected to the end of the locking plate 34 away from the rotating rod 35. When replacing the car air conditioning filter, pull the handle 32. Under the action of the handle 32, the sleeve 31 is pulled out. At this time, rotate the sleeve 31 so that the sleeve 31 is locked by the square frame 33. Rotate the gear 37. The gear 37 and its symmetrically meshing toothed plate 23 move. While the toothed plate 23 moves in the baffle 22, it drives the telescopic rod 21 to move until the telescopic rod 21 is completely disengaged from the limit plate 20. At this time, the cover plate 24 is removed to replace the car air conditioning filter.

[0025] The end of the limiting spring 36 away from the card plate 34 is fixedly connected to the inner wall of the square frame 33, the outer wall of the rotating rod 35 is fixedly connected to the outer wall of the cover plate 24, the outer wall of the toothed plate 23 is symmetrically meshed with the outer wall of the gear 37, and the outer wall of the gear 37 is rotatably connected to the outer wall of the cover plate 24.

[0026] Working principle:

[0027] When installing the car air conditioning cover 24, first place the car air conditioning filter into the housing 1. Then pull the handle 32, and the sleeve 31 will be pulled out. Then rotate the sleeve 31 so that it is locked by the outside of the square frame 33, so that the handle 32 no longer moves. The locking plate 34 rotates around the rotating rod 35, and the limiting spring 36 is compressed. At this time, the locking plate 34 is no longer in contact with the gear 37. Then press the cover 24 against the housing 1 so that the telescopic rod 21 is at the limiting plate 20. Under the pressure of the compression, the telescopic rod 21 slides in the fixed ring 27. At this time, the compression spring 25 is compressed by the collar 26 until the telescopic rod 21 is inserted into the limiting plate 20. At this time, the cover plate 24 is fixed. Rotate the sleeve 31 again to release the fixation between the sleeve 31 and the square frame 33. At this time, the clamping plate 34 is pressed by the limiting spring 36, so that the clamping plate 34 and the gear 37 mesh with each other and fix the gear 37. At this time, the gear 37 cannot rotate, so that the telescopic rod 21 cannot move, to prevent the cover plate 24 from shaking and loosening when the car is moving.

[0028] When the cover plate 24 is fixed, the convex plate 241 contacts the car air conditioning filter in the housing 1 under the push of the tension spring 242, and applies pressure to the air conditioning filter to buffer and fix it. When we need to replace the car air conditioning filter, pull the handle 32. Under the action of the handle 32, the sleeve 31 is pulled out. At this time, rotate the sleeve 31 so that the sleeve 31 is locked by the square frame 33, and rotate the gear 37. The gear 37 and its symmetrically meshing toothed plate 23 move. While the toothed plate 23 moves in the baffle 22, it drives the telescopic rod 21 to move until the telescopic rod 21 is completely disengaged from the limiting plate 20. At this time, the cover plate 24 is removed to replace the car air conditioning filter.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
