Description

Technical Field

[0001] This utility model relates to the field of quick connector technology, and in particular to a quick connector with a self-locking function. Background Technology

[0002] Quick connectors are mechanical devices used to quickly connect and disconnect pipes or mechanical components. They are widely used in hydraulic systems, pneumatic equipment, industrial fluid transmission, and engineering machinery. Their core function is to achieve reliable connections through simple operation, significantly improving equipment assembly efficiency, and they are irreplaceable, especially in scenarios requiring frequent disassembly and assembly.

[0003] Traditional quick connectors (such as those used in electronic product wiring harness connections) rely on thread tightening, elastic snap-fit, or spring clamping mechanisms for locking. These mechanisms are prone to loosening of threads or slippage of snap-fit ​​due to mechanical vibration or impact loads, leading to connection failure. To address this, we propose a quick connector with a self-locking function. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick connector with a self-locking function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The first cable is inserted into the first locking mechanism and connected to the male connector, which is fixed inside the first locking mechanism. The second locking mechanism is inserted into the first locking mechanism and locked in place. The second cable is inserted into the second locking mechanism and connected to the female connector, which is inserted into the female connector.

[0007] Preferably, the first locking mechanism includes a protective shell, the protective shell having a U-shaped structure, a connecting seat fixed at the top and bottom of the protective shell, a rotating shaft rotatably connected inside the connecting seat, a movable seat fixed on the rotating shaft, a threaded post installed on the side of the movable seat, and a threaded sleeve connected to the threaded post by threads.

[0008] Preferably, the male connector is installed inside the protective housing, and the threaded post is connected to the second locking mechanism via a threaded sleeve.

[0009] Preferably, the second locking mechanism includes a connecting plate, a fixing block is fixed to the side of the connecting plate, the fixing block is inserted into the interior of the protective shell, the second cable and the female plug are both installed on the fixing block, cavities are opened at the top and bottom of the fixing block, a movable plate is slidably connected inside the cavity, a locking tongue is fixed on the movable plate, the locking tongue passes through the cavity and is slidably connected thereto, and a support spring is installed between the locking tongue and the cavity.

[0010] Preferably, the threaded post slides into the connecting plate from the side, the locking tongue penetrates the protective shell and engages with it, and the number of support springs is several sets.

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

[0012] This utility model achieves mechanical locking and fixing of the first locking mechanism and the second locking mechanism by setting the screw-tightening cooperation between the threaded post and the threaded sleeve of the first locking mechanism, thus achieving the beneficial effects of vibration resistance and anti-loosening. By setting the nested structure of the U-shaped protective shell and the fixing block, it achieves precise alignment and full protection of the male and female plugs, solves the problem of easy loosening of traditional threaded connections, and improves the stability of the connector under complex working conditions.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-3A quick connector with self-locking function includes a first locking mechanism 1, a first cable 2, a male plug 3, a second locking mechanism 4, a second cable 5, and a female plug 6. The first cable 2 is inserted into the first locking mechanism 1 and connected to the male plug 3. The male plug 3 is fixed inside the first locking mechanism 1. The second locking mechanism 4 is inserted into the first locking mechanism 1 and locked. The second cable 5 is inserted into the second locking mechanism 4 and connected to the female plug 6. The male plug 3 is inserted into the female plug 6.

[0019] In one embodiment, the first locking mechanism 1 includes a protective shell 11, which has a U-shaped structure. Connecting seats 12 are fixed to the top and bottom of the protective shell 11. A rotating shaft 13 is rotatably connected inside the connecting seat 12. A movable seat 14 is fixed on the rotating shaft 13. A threaded post 15 is mounted on the side of the movable seat 14. A threaded sleeve 16 is threadedly connected to the threaded post 15. A male connector 3 is installed inside the protective shell 11. The threaded post 15 is connected to the second locking mechanism 4 via the threaded sleeve 16. The second locking mechanism 4 includes a connecting plate 41. A fixing block 42 is fixed to the side of the connecting plate 41 and inserted into the interior of the protective shell 11. The second cable 5 and the female connector 6 are both mounted on the fixing block 42. Cavities 43 are formed at the top and bottom of the fixing block 42. The internal sliding connection of 3 has a movable plate 44, on which a locking tongue 45 is fixed. The locking tongue 45 passes through the cavity 43 and slides therewith. A support spring 46 is installed between the locking tongue 45 and the cavity 43. The threaded post 15 slides into the connecting plate 41 from the side. The locking tongue 45 passes through the protective shell 11 and engages with it. There are several sets of support springs 46. By setting the screw-tightening cooperation between the threaded post and the threaded sleeve of the first locking mechanism, the mechanical locking and fixing of the first locking mechanism and the second locking mechanism are achieved, which achieves the beneficial effects of vibration resistance and anti-loosening. By setting the nested structure of the U-shaped protective shell and the fixing block, the precise alignment and full protection of the male and female plugs are achieved, which solves the problem of easy loosening of traditional threaded connections and improves the stability of the connector under complex working conditions.

[0020] The male plug 3 and female plug 6 are automatically aligned by the guide structure of the U-shaped protective shell 11. The fixing block 42 of the second locking mechanism 4 slides into the inner wall of the protective shell 1. When the fixing block 42 is pushed in, the locking tongue 45 is squeezed back into the cavity 43 by the inner wall of the protective shell. When the fixing block 42 is fully in place, the support spring 46 pushes the locking tongue 45 out and forms an automatic lock with the groove of the protective shell 11. The threaded column 15 is rotated to slide into the side of the connecting plate 41. Then, the threaded sleeve 16 is screwed close to the connecting plate 41 through the thread to complete the locking of the first locking mechanism 1 and the second locking mechanism 4, eliminating the fit gap. The spring locking tongue 45 absorbs energy through elastic deformation when vibrating. The threaded locking prevents large displacement and loosening. When separating, the threaded sleeve 16 is rotated in the opposite direction to release the mechanical locking. The locking tongue 45 is manually pressed to overcome the spring force 46 and retract. The second locking mechanism 4 is pulled out along the axis to achieve rapid separation.

[0021] In summary, compared with the prior art, this utility model achieves mechanical locking and fixing of the first locking mechanism and the second locking mechanism by setting the screw-tightening cooperation between the threaded post and the threaded sleeve of the first locking mechanism, thus achieving the beneficial effects of vibration resistance and anti-loosening. By setting the nested structure of the U-shaped protective shell and the fixing block, it achieves precise alignment and full protection of the male and female plugs, solves the problem of easy loosening of traditional threaded connections, and improves the stability of the connector under complex working conditions.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
