Description
Technical Field
[0001] This utility model relates to the field of AG glass cover fixing technology, specifically a vehicle-mounted AG glass cover fixing component. Background Technology
[0002] AG glass covers combined with video imaging screens can form transparent anti-glare and anti-reflective screens, solving the problems of reflection and glare caused by ambient light in electronic video and image screens, improving image quality. They are widely used in touch screens, flat-panel TVs, LCD monitors, touch screens, industrial instruments, and high-end picture frames. In production, after pretreatment such as water washing and acid washing, the glass enters a frosting bath for frosting and etching. The frosted glass then undergoes water washing and polishing thinning processes to produce AG glass.
[0003] In existing technologies, the functional holes on the surface of AG glass covers are positioned and polished using clamps that directly hold the glass. This clamping method is rigid, which can easily cause the glass to break during polishing. In addition, the clamping process requires repeated adjustments during the limiting process, which is inefficient. If clamps such as cylinders are used, the cost is high and the electrified operation has a high failure rate and is prone to damage. Therefore, it is necessary to provide a new type of vehicle-mounted AG glass cover fixing component to solve the above technical problems. Utility Model Content
[0004] The purpose of this utility model is to provide a vehicle-mounted AG glass cover fixing component, which has the advantages of flexible fixing, fast and efficient operation, low cost and low failure rate, and solves the problems in the background technology.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle-mounted AG glass cover fixing assembly, comprising: a fixing plate, two suction cups fixedly connected to the top of the fixing plate, connecting tubes fixedly connected to the bottom of each of the two suction cups, a sleeve fixedly connected to the outside of the two connecting tubes, a piston slidably connected inside the sleeve, a sliding rod fixedly connected to the bottom of the piston, one-way toothed grooves evenly formed on the outside of the sliding rod, a fixing frame sleeved on the outside of the sliding rod, a fixing frame fixedly connected to the bottom of the fixing frame, a one-way rack slidably connected inside the fixing frame, and a paddle fixedly connected to the outside of the one-way rack. In use, the device is installed in a suitable position. When fixing the glass cover, the two suction cups contact the glass cover, and then the sliding rod is pulled to cause the piston to move within the sleeve. The piston slides downward inside the sleeve. When the piston slides downward inside the sleeve, a negative pressure is formed inside the sleeve. Through the connection of the connecting tube, the two suction cups can simultaneously form a negative pressure. Through the negative pressure, the two suction cups can adsorb and fix the glass cover plate. Compared with the rigid contact of traditional clamps, it is more gentle and stable. When the slide rod is pulled and slides downward inside the fixing frame, the engagement of the one-way rack and one-way tooth groove allows the slide rod to slide downward quickly in one direction inside the fixing frame. Even when the negative pressure is released, the negative pressure inside the suction cup can be maintained. When it is necessary to unlock and release the adsorption and limiting of the glass cover plate, simply move the lever to disengage the one-way rack from the one-way tooth groove, and the piston will slide upward inside the sleeve. At the same time, the air pressure inside the suction cup will return to normal, and the slide rod can be released.
[0006] Preferably, the fixing frame is fixedly connected to the bottom of the fixing plate, and the fixing frame has a square hole inside. The sliding rod slides inside the square hole. The fixing frame can set a limit for the entire sliding rod, and the square hole can limit the sliding trajectory of the sliding rod.
[0007] Preferably, both connecting tubes penetrate the entire interior of the fixed plate, and the two connecting tubes are respectively fixedly connected to the outside of both sides of the sleeve. The one-way rack and one-way tooth groove mesh, so that when a negative pressure is formed inside the sleeve, a negative pressure is simultaneously formed inside the two suction cups through the connecting tubes.
[0008] Preferably, the fixed frame has a sliding groove on its outside, the paddle is engaged inside the sliding groove, the one-way rack slides inside the fixed frame and extends to the outside of the fixed frame, and the sliding groove can limit the sliding trajectory of the paddle.
[0009] Preferably, a return spring is fixedly connected to one side of the one-way rack inside the fixed frame. The return spring is sleeved inside the fixed frame, and the elastic force of the return spring can act in the opposite direction on the outside of the one-way rack, so that the one-way rack is always locked outside the one-way tooth groove.
[0010] Preferably, mounting plates are fixedly connected to both sides of the fixed frame, and mounting holes are provided inside the mounting plates. The combination of mounting plates and mounting holes facilitates the assembly and installation of the overall device.
[0011] Preferably, a cap is fixedly connected to the bottom of the slide rod, and the cap allows the user to apply force to control the sliding and lifting adjustment of the slide rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] I. When using this utility model, the device is installed in a suitable position. When fixing the glass cover, the two suction cups contact the glass cover. Then, the sliding rod is pulled to make the piston slide downward inside the sleeve. When the piston slides downward inside the sleeve, a negative pressure is formed inside the sleeve. Through the connection of the connecting tube, the two suction cups can be made to form a negative pressure simultaneously. Through the negative pressure, the two suction cups can adsorb, fix and limit the glass cover. Compared with the rigid contact of traditional clamps, it is more gentle and stable.
[0014] II. In this utility model, when the sliding rod is pulled down inside the fixed frame, the engagement of the one-way rack and the one-way tooth groove allows the sliding rod to slide down quickly in one direction inside the fixed frame. This achieves negative pressure limit locking and maintains negative pressure inside the suction cup even when the hand is released. When it is necessary to unlock and release the suction limit on the glass cover, simply move the lever to disengage the one-way rack from the one-way tooth groove, allowing the piston to slide up inside the sleeve. Simultaneously, the air pressure inside the suction cup returns to normal, thus releasing the limit on the sliding rod. Attached Figure Description

In use, the device is installed in a suitable position. When fixing the glass cover, the two suction cups 4 contact the glass cover, and then the sliding rod 6 is pulled to make the piston 13 slide downward inside the sleeve 5. When the plug 13 slides downward inside the sleeve 5, a negative pressure is formed inside the sleeve 5. Through the connection of the connecting pipe 8, the two suction cups 4 can be synchronously formed with negative pressure. Through the negative pressure, the two suction cups 4 can be used to adsorb, fix and limit the glass cover. Compared with the rigid contact of the traditional clamp, it is more gentle and stable. When the slide rod 6 is pulled and slides downward inside the fixing frame 2, the engagement of the one-way rack 14 and the one-way groove 12 allows the slide rod 6 to slide downward quickly in one direction inside the fixing frame 2. When the negative pressure limit lock is released, the negative pressure inside the suction cup 4 can be maintained. When it is necessary to unlock and release the adsorption limit of the glass cover, it is only necessary to move the lever 16 to disengage the one-way rack 14 from the one-way groove 12, so that the piston 13 can slide upward inside the sleeve 5. The air pressure inside the suction cup 4 will return to normal, and the limit of the slide rod 6 can be released.
[0023] The fixing frame 2 is fixedly connected to the bottom of the fixing plate 1. The fixing frame 2 has a square hole inside. The sliding rod 6 slides inside the square hole. The fixing frame 2 can set the limit for the entire sliding rod 6. The square hole can limit the sliding trajectory of the sliding rod 6.
[0024] Both connecting pipes 8 pass through the entire interior of the fixed plate 1. At the same time, the two connecting pipes 8 are fixedly connected to the outside of both sides of the sleeve 5. The one-way rack 14 meshes with the one-way tooth groove 12. When a negative pressure is formed inside the sleeve 5 through the connecting pipes 8, a negative pressure is simultaneously formed inside the two suction cups 4.
[0025] The fixed frame 10 has a groove 11 on its outside. The paddle 16 is locked inside the groove 11. The one-way rack 14 slides inside the fixed frame 10 and extends to the outside of the fixed frame 10. The groove 11 can limit the sliding trajectory of the paddle 16.
[0026] A return spring 15 is fixedly connected to one side of the one-way rack 14 inside the fixed frame 10. The return spring 15 is sleeved inside the fixed frame 10. The elastic force of the return spring 15 can act in the opposite direction on the outside of the one-way rack 14, so that the one-way rack 14 is always locked outside the one-way tooth groove 12.
[0027] Mounting plates 3 are fixedly connected to both sides of the fixed frame 2. Mounting plates 3 have mounting holes 9 inside. The combination of mounting plates 3 and mounting holes 9 facilitates the assembly and installation of the whole device.
[0028] When using this vehicle-mounted AG glass cover fixing assembly, two suction cups 4 contact the glass cover, and then the slide rod 6 is pulled to make the piston 13 slide downward inside the sleeve 5. When the piston 13 slides downward inside the sleeve 5, a negative pressure is formed inside the sleeve 5. Through the connection of the connecting pipe 8, the two suction cups 4 can be synchronously formed with negative pressure. Through the negative pressure, the two suction cups 4 can adsorb, fix and limit the glass cover.

[0030] When the vehicle-mounted AG glass cover fixing assembly is in use, the engagement of the one-way rack 14 and the one-way groove 12 allows the slide rod 6 to slide quickly downward in one direction inside the fixing frame 2. This achieves negative pressure limit locking and maintains negative pressure inside the suction cup 4 even when the hand is released. When it is necessary to unlock and release the suction limit of the glass cover, simply move the lever 16 to disengage the one-way rack 14 from the engagement of the one-way groove 12.
