Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fixture installation, in particular to a locking mechanism suitable for quick disassembly of fixtures. Background Technique
[0002] Fixtures are tools used to fix, position and hold workpieces in industrial production, and they play an important role in the processes of machining, assembly and testing. Fixtures are classified in various ways, including process assembly fixtures, project testing fixtures, circuit board testing fixtures, etc. These fixtures can be made of materials such as metal and plastic, and have specific shapes and sizes to meet different application requirements.
[0003] At present, the traditional way of fixture installation is mostly to directly use screw installation. When changing the production line, that is, when changing the product model for production, screws need to be repeatedly disassembled and assembled, which lengthens the changeover time, delays time, and makes the changeover more troublesome. Moreover, during the repeated tightening and disassembly of screws, it will affect the accuracy of the fixture on the positioning plate, and there are also problems such as the screw holes slipping due to repeated disassembly and assembly, and the screws rusting due to humid environment, which will cause the fixing seat to fail after long-term use, resulting in the scrapping of parts. In addition, tools such as screwdrivers required for disassembling and assembling screws also need to be stored in a certain position. If they are not placed properly, they are easy to be lost. Once lost, it will affect the product changeover and increase the maintenance cost. Content of the Utility Model
[0004] In view of the deficiencies of the prior art, the utility model provides a locking mechanism suitable for quick disassembly of fixtures, and solves the problems put forward in the above background technique.
[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A locking mechanism suitable for quick disassembly of fixtures, including a fixture mounting seat, an air vent passage is opened inside the fixture mounting seat, one end of the air vent passage is provided with an air vent, a quick-release male head is inserted inside the air vent passage, a quick-release female head is sleeved on the surface of the quick-release male head, movable beads are arranged on the surface of the quick-release male head, and a groove ring is opened on the inner side wall of the quick-release female head.
[0006] Optionally, a sealing plug is arranged at the other end of the air vent passage, and the top end of the quick-release male head protrudes from the surface of the fixture mounting seat.
[0007] Optionally, the size of the movable beads is adapted to the size of the groove ring.
[0008] Optionally, a piston column is arranged inside the quick-release male head, and a top support inclined surface is arranged at the top end of the piston column.
[0009] Optionally, an air stop valve for preventing air leakage is arranged inside the air vent.
[0010] The present utility model provides a locking mechanism suitable for quick disassembly of fixtures, having the following beneficial effects:
[0011] For the locking mechanism suitable for quick disassembly of fixtures, the quick-release female head is installed at the bottom of the fixture, and then air is inflated into the air passage in the fixture mounting base through the air vent, so that the movable beads on the quick-release male head protrude and are stuck in the groove of the quick-release female head to lock and fix the fixture. It can effectively achieve the quick installation and disassembly of the fixture, save the product changeover time, and at the same time avoid the thread hole from slipping due to repeated disassembly and assembly of the screw fixation, thus preventing the fixture mounting base from being scrapped. Moreover, the inflation operation is simple, and there is no need to use special tools to tighten or loosen the fixture. As long as the air supply and cut-off are controlled, quick disassembly can be achieved, effectively avoiding the influence of tool problems on disassembly and assembly and reducing its maintenance cost. This mechanism can be applied to most fixtures with quick disassembly and replacement, and at the same time has low requirements for workers. Description of the Drawings

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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 of the embodiments.
[0017] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a locking mechanism suitable for quick disassembly of fixtures, including a fixture mounting base 1. An air passage 2 is opened inside the fixture mounting base 1. One end of the air passage 2 is provided with an air vent 3. An air stop valve 11 for preventing air leakage is arranged inside the air vent 3. After inflation, the air stop valve 11 can block the air vent 3 to keep the air passage 2 in a full-air state all the time. Then, when disassembling, the air is directly released through the air stop valve 11 to separate the fixture from the fixture mounting base 1;
[0018] The inside of the ventilation channel 2 is inserted with a quick-release male head 4. The top end of the quick-release male head 4 protrudes from the surface of the fixture mounting base 1. A quick-release female head 5 is sleeved on the surface of the quick-release male head 4. A movable bead 7 is arranged on the surface of the quick-release male head 4. A groove ring 8 is formed on the inner side wall of the quick-release female head 5. A piston column 9 is arranged inside the quick-release male head 4. A top support inclined surface 10 is arranged at the top end of the piston column 9. The size of the movable bead 7 is adapted to the size of the groove ring 8. In the non-ventilated state, the movable bead 7 on the quick-release male head 4 is in a free state, that is, a floating state. The finger can press the movable bead 7, and at this time the movable bead 7 is not stressed. When ventilated, the piston column 9 inside the quick-release male head 4 moves upward. During the upward movement, due to the upward movement of the top support inclined surface 10, at this time the top support inclined surface 10 of the piston column 9 pushes the movable bead 7 outwards. At this time, there is a reaction force when pressing the movable bead 7 with the hand. Using this principle, the state of the movable bead 7 can be controlled under the condition of air on and off to be stuck in the groove ring 8 of the quick-release female head 5, so as to play the role of locking and loosening the quick-release fixture;
[0019] By means of this mechanism, the product changeover time can be saved. At the same time, it is avoided that the repeated disassembly and assembly of the threaded holes due to screw fixation result in thread slipping and the screws rusting due to the humid environment, thus causing the fixture mounting base 1 to be scrapped. Moreover, the inflation operation is simple and does not require special tools to tighten or loosen the fixture. As long as the air on and off is controlled, quick release can be achieved, effectively avoiding the influence on disassembly and assembly due to tool problems and reducing its maintenance cost. This mechanism can be applied to most fixtures with quick release and quick change, and at the same time has relatively low requirements for workers.
[0020] In the present utility model, the working steps of the device are as follows:
[0021] During installation, first install the quick-release female head 5 at the bottom of the fixture, and then inflate the ventilation channel 2 inside the fixture mounting base 1 through the ventilation port 3. The gas squeezes the piston column 9 inside the quick-release male head 4, making it move upward. During the upward movement, the top support inclined surface 10 at the top end of the piston column 9 will move upward to push open the movable bead 7, which protrudes and is stuck in the groove ring 8 of the quick-release female head 5 to complete the locking installation of the fixture;
[0022] When disassembling, directly deflate through the air stop valve 11. The piston column 9 falls under the influence of gravity, the movable bead 7 is no longer squeezed, the quick-release male head 4 is retracted, and the quick-release female head 5 is loosened, that is, the fixture can be separated from the fixture mounting base 1 to complete the disassembly of the fixture.
[0023] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacement or change, and should be covered by the protection scope of the present utility model.
