Description

Technical Field

[0001] This invention discloses a plug-in self-locking connector and handle replacement structure, belonging to the technical field of detachable connector and handle connection design. Background Technology

[0002] Quick-release mechanisms between connectors and handles are widely used in daily life and industrial applications. Traditional connection methods often employ threaded connections or snap-fit ​​connections. However, threaded connections are cumbersome to install and remove, requiring multiple rotations and resulting in low efficiency; existing snap-fit ​​connections have poor stability and are prone to loosening or breakage due to external forces or prolonged use, leading to low reliability. Therefore, there is an urgent need for a replacement mechanism that is simple in structure, easy to operate, reliable in connection, and has a long service life. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a plug-in self-locking connector and handle replacement structure.

[0004] The objective of this invention is achieved as follows: a plug-in self-locking connector and handle replacement structure, including a connector and a handle; characterized in that: at least two pins are fixed at one end of the connector and the handle, one end of the pins is fixed to the connector, and the other end is inclined and bent to form a sloping guide portion;

[0005] The end of the handle connected to the connector has at least two latching slots, the number of which is the same as the number of pins. Each latching slot includes a slot hole and a latching hole. The slot hole is located at the end of the handle connected to the connector, and the latching hole is located on the side of the slot hole and communicates with the slot hole.

[0006] When the connector needs to be plugged into the handle, the pins on the connector are inserted into the corresponding snap-fit ​​slots on the handle. During this process, the beveled guide part of the pin is pressed inward and enters the slot hole. When the beveled guide part reaches the snap-fit ​​hole, the beveled guide part automatically resets and partially protrudes from the snap-fit ​​hole. The pins on the connector automatically engage and lock with the snap-fit ​​slots on the handle, thus the connector is plugged into the handle in a self-locking manner.

[0007] When the connector needs to be removed from the handle, press the beveled guide of the pin to bend it. The beveled guide will retract into the snap-fit ​​hole, and the pin will exit from the slot hole of the snap-fit ​​groove, thus separating the connector from the handle.

[0008] The connector is also provided with a plug rod at one end and a slot matching the plug rod at the other end. When the plug rod is inserted into the slot, it stabilizes the connector and the handle.

[0009] The connector is fixedly equipped with bristles or a scraper, and the connector has bristle insertion holes when bristles are inserted.

[0010] The handle has a hanging hole at the end for easy hanging.

[0011] The handle is provided with an anti-slip layer to prevent slippage.

[0012] When the connector is fixed with bristles, the bristles are fixed to the connector by means of bristle insertion or bristle loading.

[0013] This utility model features a reasonable and simple structure, and is easy to use. The connector has pins with beveled guides, and the handle has corresponding locking slots (including slot holes and locking holes). During insertion, the beveled guides of the pins are pressed inwards and automatically reset upon reaching the locking holes, achieving self-locking. During disassembly, pressing the beveled guides causes them to retract, allowing the pins to exit the slot holes.

[0014] Furthermore, the connector is equipped with a plug rod, and the handle has a corresponding slot. Inserting the plug rod into the slot can enhance the connection stability.

[0015] When in use, the connector can fix the bristles, scraper, or other parts. The bristles can be fixed by inserting or mounting bristles.

[0016] This invention simplifies the insertion and separation process, eliminating the need for rotation or complex operations; its self-locking design ensures a secure connection that is not easily loosened; and its simple structure reduces wear caused by frequent disassembly and assembly.

[0017] In summary, this utility model provides a quick-change structure that is simple in structure, convenient in operation, and reliable in connection through a plug-in self-locking design, and has broad market application and promotion value. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0024] A plug-in self-locking connector and handle replacement structure includes a connector 1 and a handle 2; at least two pins 3 are fixed at one end of the connector 1 and the handle 2, one end of the pins 3 is fixed to the connector 1, and the other end is bent at an angle to form a sloping guide portion 4.

[0025] At least two latching slots 5 are provided at the end where the handle 2 is connected to the connector 1. The number of latching slots 5 is the same as that of the pins 3. The latching slots 5 include a slot hole 5-1 and a latching hole 5-2. The slot hole 5-1 is opened at the end where the handle 2 is connected to the connector 1. The latching hole 5-2 is opened on the side of the slot hole 5-1 and is connected to the inside of the slot hole 5-1.

[0026] When connector 1 needs to be plugged into handle 2, the pin 3 on connector 1 is inserted into the corresponding snap-fit ​​slot 5 on handle 2. During this process, the inclined guide part 4 of pin 3 is pressed inward and enters the slot hole 5-1. When the inclined guide part 4 reaches the snap-fit ​​hole 5-2, the inclined guide part 4 automatically resets and partially protrudes from the snap-fit ​​hole 5-2. The pin 3 on connector 1 automatically engages and locks with the snap-fit ​​slot 5 on handle 2, so that connector 1 is plugged into and self-locked onto handle 2.

[0027] When connector 1 needs to be removed from handle 2, press the beveled guide 4 of pin 3 to bend it. The beveled guide 4 retracts into the snap hole 5-2, and pin 3 exits from the slot hole 5-1 of snap groove 5, thus separating connector 1 from handle 2.

[0028] Furthermore, a plug rod 6 is provided at the end where the connector 1 is connected to the handle 2, and a slot 7 matching the plug rod 6 is provided at the end where the handle 2 is connected to the connector 1. When the plug rod 6 is inserted into the slot 7, it plays a role in stabilizing the connector 1 and the handle 2. When hair is implanted, hair implantation holes 8 are provided on the connector 1.

[0029] The handle 2 has a hanging hole 9 at its tail for easy hanging. The handle 2 is also provided with an anti-slip layer 10 to prevent slippage.

[0030] Furthermore, during use, a brush or scraper is fixedly installed on the connector 1. When the connector 1 is fixed with brush bristles, the bristles are fixed to the connector 1 by means of bristle insertion or bristle loading.

[0031] The above description is merely an example and illustration of the present utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the present utility model.
