Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a quick-lock connector. Background Technique

[0002] In electrical applications, such as during the use of equipment, instruments, and electronic devices, in order to maintain the power supply of the equipment to support its normal operation or ensure data transmission between devices, it is usually necessary to connect the device with a wire and then connect the plug on the wire to the corresponding port to maintain the operation of the device or the data transmission of the device.

[0003] When the wire is connected to the port through the plug, if there are active personnel in the surrounding environment, it may occur that due to the accidental touch of the active personnel, the connection between the plug and the corresponding port becomes loose or even directly falls off, resulting in poor contact or disconnection between the plug and the port, which has an adverse impact on the normal operation of the device. Therefore, a quick-lock connector is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a quick-lock connector to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A quick-lock connector, including a positioning ring, an installation plate is fixedly connected to the outer end of the positioning ring, an adjusting plate and a locking block are respectively installed on both sides inside the positioning ring, the adjusting plate is slidably connected to the inside of the positioning ring, and one end of the locking block extends into the inner cavity of the positioning ring.

[0006] Based on the above technical solution, the utility model can also be improved as follows.

[0007] Preferably, limiting grooves are respectively opened on both sides of the inner cavity of the positioning ring.

[0008] Preferably, a connecting rod is fixedly connected to one end of the locking block close to the adjusting plate, and a sliding rod is fixedly connected to the end of the connecting rod far from the locking block.

[0009] Preferably, a sliding groove is opened on the inner side of the adjusting plate, and the sliding rod is slidably connected to the sliding groove.

[0010] Preferably, the outer surface of the locking block close to the outer side of the positioning ring is a smooth inclined surface.

[0014] Advantageous Effects

[0015] Compared with the prior art, the technical solution of the present application has the following advantageous technical effects:

[0016] In the present utility model, by providing a locking block, after the plug is inserted into the positioning ring, the plug's contact with the locking block can drive the locking block to move away from the plug. At the same time, under the pushing action of the return spring on the adjusting plate, the sliding rod slides in a limited manner in the sliding groove, and then the connecting rod drives the locking block to slide back towards the plug to quickly lock the plug, preventing accidental contact with the plug, which may cause the connection between the plug and the port to become loose or fall off.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] A quick-locking connector includes a positioning ring 1. The outer end of the positioning ring 1 is fixed with a mounting plate 2. The mounting plate 2 is installed on the outside of the port where the connector needs to be docked according to the situation, and the mounting plate 2 can be installed and fixed by bolts. After the plug to be connected is inserted into the positioning ring 1, it can be connected to the port.

[0023] In this embodiment, as Figures 1-3, on both inner sides of the positioning ring 1, an adjusting plate 3 and a locking block 5 are respectively arranged. The adjusting plate 3 and the locking block 5 are both arranged in two groups, and on both sides of the inner cavity of the positioning ring 1, limiting grooves 11 are respectively arranged. The locking block 5 slides in a limited manner in the limiting groove 11. At the same time, one end of the locking block 5 extends into the inner cavity of the positioning ring 1, so as to lock the plug inserted into the positioning ring 1, prevent the plug from falling off due to accidental touch when the plug is connected to the port, and affect the transmission between the plug and the port.

[0024] Specifically, a connecting rod 51 is fixed at one end of the locking block 5 close to the adjusting plate 3, and a sliding rod 52 is fixed at one end of the connecting rod 51 far from the locking block 5. At the same time, the adjusting plate 3 is slidably connected to the inside of the positioning ring 1, and a sliding groove 31 for slidably connecting with the sliding rod 52 is arranged on the inner side of the adjusting plate 3. The sliding range of the sliding rod 52 is limited by the sliding groove 31, so that when the adjusting plate 3 slides, it can drive the sliding rod 52 to slide in a limited manner. Since the connecting rod 51 is respectively fixed to the sliding rod 52 and the locking block 5, when the sliding rod 52 slides in the sliding groove 31, it will drive the locking block 5 to slide in the limiting groove 11. When the two locking blocks 5 slide towards the inner cavity of the positioning ring 1 at the same time, the plug inserted into the positioning ring 1 is tightened and blocked by the end of the locking block 5 extending into the inner cavity of the positioning ring 1, thereby locking the plug and preventing the plug from falling off.

[0025] Furthermore, the outer surface of the locking block 5 close to the outer side of the positioning ring 1 is an inclined surface, and the surface of the inclined surface is smooth. So that when the plug is inserted into the positioning ring 1 and presses against the inclined surface of the locking block 5, the locking block 5 will slide towards the side away from the plug and be received in the limiting groove 11. At the same time, a return spring 6 fixed to the adjusting plate 3 is arranged inside the positioning ring 1. The adjusting plate 3 is pushed by the natural elastic force of the return spring 6, so that the adjusting plate 3 can slide by itself, and then the locking block 5 slides towards the inner cavity of the positioning ring 1 to quickly lock the plug.

[0026] Furthermore, a pressing rod 4 is fixed at one end of the adjusting plate 3 far from the return spring 6. The pressing rod 4 extends to the outside of the positioning ring 1. By pressing the pressing rod 4, the adjusting plate 3 can be driven to slide, and then the locking block 5 is prompted to slide towards the side away from the inner cavity of the positioning ring 1, so that the locking block 5 is received in the limiting groove 11, so as to pull out the plug from the inner cavity of the positioning ring 1.

[0027] In another embodiment, as Figure 2 and Figure 3 , a sealing gasket 7 is bonded to the inner end of the mounting plate 2 on the side far from the positioning ring 1, so as to be in close contact with the outer contact surface of the port through the sealing gasket 7 to improve the dust and water protection effect.

[0028] Working principle: First, place the positioning ring 1 outside the port through the mounting plate 2. The inner cavity of the positioning ring 1 is aligned with the port, and the mounting plate 2 is fixed by bolts. When the plug needs to be docked with the port, directly insert the plug into the inner cavity of the positioning ring 1. At this time, the inclined surface of the locking block 5 contacts and presses against the plug, enabling the locking block 5 to slide into the limiting groove 11. Then, under the pushing action of the return spring 6 on the adjusting plate 3, the sliding rod 52 slides in the sliding groove 31, and further drives the locking block 5 to slide towards one end of the inner cavity of the positioning ring 1 through the connecting rod 51, so that the locking blocks 5 on both sides press against and block the plug, preventing the plug from falling off or loosening and having poor contact with the port when a person accidentally touches the plug.
