Description

Technical Field

[0001] This invention relates to the field of handle connection structures, and more specifically to a connector for a handle. Background Technology

[0002] With the continuous development of technology, the stability and convenience of the connection structure of the handle, as an important operating component of various devices, are receiving increasing attention. In existing technologies, there are various ways to connect the handle to the device body, among which the pin-type connection is widely used due to its simple structure and stable connection.

[0003] Currently, common handle connection structures on the market mainly include threaded connections, snap-fit ​​connections, and pin connections. Among them, pin-type handles typically include components such as buttons, sliding sleeves, pins, and pin sleeves. Connection is achieved by inserting the pin into a socket at the bottom of the device. This connection method reduces handle weight, improves sealing, and facilitates disassembly and maintenance. CN204076209U discloses a pin-type handle that uses a pin connection to a socket at the bottom of the housing, achieving a detachable handle design for easy maintenance and replacement.

[0004] In handle connection structures, the locking mechanism is a key component ensuring connection stability. CN218762195U discloses a side-mounted handle, which includes a handle body and a disassembly assembly. The disassembly assembly can slide relative to the handle body and, through a drive mechanism, drives the locking mechanism to lock or unlock the connector, thus improving connection stability. Similarly, CN113314904A proposes a gap-fitting connector device with an operating mechanism, which uses multiple conductive bars to install the circuit breaker and connector body via a plug-in method, simplifying the connection structure and improving installation efficiency.

[0005] For handle connection structures that require frequent disassembly and assembly, ease of operation is also an important consideration. CN108581907A discloses a multi-functional wrench, which, by setting up components such as an adjusting rod, adjusting sleeve, and connecting rod, enables quick replacement and adjustment of the wrench head, improving operational efficiency and flexibility. CN213400968U proposes a combination switch handle structure, which, by setting up components such as a fixing seat, stop block, and pressure plate in the handle, meets the diverse requirements of handle operation functions and methods.

[0006] However, existing handle connection structures still have some shortcomings. First, traditional pin-type connection structures often lack an effective locking mechanism, making them prone to loosening or even detachment during use, affecting safety and stability. Second, existing locking mechanisms are complex in design and cumbersome to operate, requiring tools to connect or disconnect, hindering quick user operation. Furthermore, some connection structures have poor compatibility, failing to adapt to different handle or device models, limiting their application range. Finally, existing connection structures require high precision in the fit between components, resulting in high manufacturing costs and susceptibility to wear and tear over long-term use, affecting their lifespan.

[0007] Therefore, there is an urgent need for a handle connector that is simple in structure, easy to operate, has a stable connection, and is highly applicable, in order to solve the problems existing in the prior art. Summary of the Invention

[0008] To address the issues of insecure fixing and inconvenient operation in existing handle connection structures, and to achieve the goals of quick fixing and release, simple operation, and structural stability, this invention provides a connector for handles.

[0009] The technical solution adopted by the present invention to solve its technical problem is: to provide a connector for a handle, including a pin fixing plate, a pin fixing plate and a pin, wherein the pin fixing plate and the pin fixing plate are arranged opposite to each other, the pin passes through the locking slider, and one end of the pin passes through the pin fixing plate and the other end passes through the pin fixing plate, and the pin, the pin, the pin fixing plate and the pin fixing plate are all clearance fit or transition fit.

[0010] Preferably, the locking slider is disposed between the pin fixing plate and the pin fixing plate, and the locking slider can slide in a direction perpendicular to the pin, and the locking slider, the pin fixing plate, and the pin fixing plate maintain a sliding fit.

[0011] Furthermore, the upper end of the locking slider is provided with a control button, which is detachably connected to the locking slider or integrally formed; the lower end of the locking slider is provided with a return spring, one end of which abuts against the lower end of the locking slider, and the other end is used to abut against the external structure.

[0012] Optionally, the pin fixing plate has at least three first connecting holes, which are evenly distributed or arrayed along the circumference of the pin fixing plate, and the axis of the first connecting holes is parallel to the axis of the pin, for inserting a fixing member to connect to the external handle structure.

[0013] Preferably, the pin fixing plate is provided with a second connecting hole, the number, diameter and axis of the second connecting hole are all corresponding to the first connecting hole, and are used to cooperate with the first connecting hole to insert a fixing member, so as to realize the relative positioning of the pin fixing plate and the pin fixing plate.

[0014] Furthermore, a first limiting block is provided on the side of the locking slider near the pin fixing plate. The first limiting block is integrally formed or welded to the locking slider, and the first limiting block extends to the top of the pin fixing plate to limit the maximum downward stroke of the locking slider. The control button is fixed on the first limiting block by interference fit or threaded connection.

[0015] Optionally, a second limiting block is provided on the side of the locking slider near the pin fixing plate below it. The second limiting block is integrally formed with the locking slider or bolted to it. The reset spring is sleeved on the outer periphery of the second limiting block or fixedly connected to the lower end of the second limiting block. A limiting groove extending along the sliding direction of the locking slider is opened below the pin fixing plate. The second limiting block is embedded in the limiting groove and slides against the inner wall of the limiting groove. The limiting groove is used to limit the movement trajectory of the second limiting block, thereby constraining the sliding direction of the locking slider.

[0016] Preferably, the middle part of the locking slider is a hollow structure, and the diameter of the hollow structure is adapted to the outer diameter of the pin, so that the pin can pass through the hollow structure of the locking slider; the middle part of the inner wall of the locking slider extends inward to form a limiting platform, which is used to abut against the fixing rod that passes through the first connecting hole and the second connecting hole to achieve axial positioning of the fixing rod.

[0017] Furthermore, the fixing and releasing of the fixing component are achieved by the sliding of the locking slider between the pin fixing disc and the pin fixing plate: when the locking slider slides downward, the inner wall of the locking slider is interference-fitted with the fixing component or engages with the groove on the fixing component through the protrusion structure, thereby fixing the fixing component; when the locking slider slides upward, the inner wall of the locking slider is clearance-fitted with the fixing component or the protrusion structure disengages from the groove, thereby releasing the fixing component.

[0018] Optionally, the control button is used to drive the locking slider to slide: when the control button is pressed towards the limit groove, the locking slider can be driven to slide downward against the elastic force of the return spring, thereby unlocking the fastener; the elastic force of the return spring is opposite to the pressing direction of the control button, and is used to push the locking slider to reset after the control button is released, thereby fixing the fastener.

[0019] The beneficial effects of this utility model are as follows: Through a special locking slider structure, the fastener can be quickly fixed and released. Compared with the connection structure of the prior art that requires complicated operation, the present invention can be unlocked by simply pressing the control button. After release, the reset spring automatically resets the fastener, greatly improving the convenience of operation. The coordinated design of the first limit block, the second limit block and the limit groove ensures that the movement trajectory of the locking slider is controllable, making the connection structure more stable and reliable. The connector has a simple structure and is suitable for various handle connection scenarios. It effectively improves the stability and ease of use of the handle connection and solves the problems of unstable fixation and inconvenient operation in the existing handle connection structure.

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0027] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0028] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figure 1-6As shown, a handle connector includes a pin retaining plate 1, a pin retaining plate 5, and a pin 6. The pin retaining plate 1 and the pin retaining plate 5 are arranged opposite to each other, with one end of the pin 6 passing through the pin retaining plate 1 and the other end passing through the pin retaining plate 5. The pin 6, the pin retaining plate 1, and the pin retaining plate 5 are all clearance fit or transition fit, which allows the pin 6 to be securely installed between the pin retaining plate 1 and the pin retaining plate 5 while ensuring a certain level of assembly accuracy.

[0030] A locking slider 2 is provided between the pin fixing plate 1 and the pin fixing plate 5. The locking slider 2 can slide in a direction perpendicular to the pin 6, maintaining a sliding fit with both the pin fixing plate 1 and the pin fixing plate 5. This design allows the locking slider 2 to slide freely in a direction perpendicular to the pin 6, thereby achieving the locking and releasing functions of the fixing component. The pin 6 passes through the locking slider 2, ensuring that the locking slider 2 maintains a relative position with the pin 6 throughout the sliding process.

[0031] The upper end of the locking slider 2 is equipped with a control button 3. The control button 3 and the locking slider 2 can be detachably connected or integrally formed. When a detachable connection is used, it facilitates the replacement and maintenance of the control button 3; when an integrally formed structure is used, it improves the stability and durability of the overall structure. The lower end of the locking slider 2 is equipped with a return spring 4. One end of the return spring 4 abuts against the lower end of the locking slider 2, and the other end is used to abut against an external structure. The return spring 4 provides an upward elastic force, allowing the locking slider 2 to automatically return to the locked position when no external force is applied.

[0032] The pin retaining plate 1 has at least three first connecting holes 101, which are evenly distributed or arranged in an array along the circumference of the pin retaining plate 1. The axis of the first connecting holes 101 is parallel to the axis of the pin 6 and is used to pass through a fixing member to connect to the external handle structure. The distribution of three or more connecting holes can provide a more stable connection and prevent loosening or displacement during use.

[0033] The pin fixing plate 5 has a second connecting hole 502. The number, diameter, and axis of the second connecting holes 502 correspond one-to-one with the first connecting holes 101. These holes are used to mate with the first connecting holes 101 to insert a fixing component, thereby achieving relative positioning between the pin fixing disc 1 and the pin fixing plate 5. This corresponding design ensures precise alignment between the pin fixing disc 1 and the pin fixing plate 5, improving the stability and service life of the overall structure.

[0034] A first limiting block 201 is provided on the side of the locking slider 2 near the pin fixing plate 5. The first limiting block 201 is integrally formed or welded to the locking slider 2. The first limiting block 201 extends above the pin fixing plate 5 to limit the maximum downward sliding stroke of the locking slider 2 and prevent excessive sliding of the locking slider 2 from causing structural damage. The control button 3 is fixed to the first limiting block 201 by interference fit or threaded connection. This connection method ensures a firm connection between the control button 3 and the locking slider 2.

[0035] A second limiting block 202 is provided below the locking slider 2 on the side near the pin fixing plate 5. The second limiting block 202 is integrally formed with the locking slider 2 or bolted to it. A return spring 4 is sleeved on the outer periphery of the second limiting block 202 or fixedly connected to the lower end of the second limiting block 202, providing an upward elastic force to reset the locking slider 2. A limiting groove 501 extending along the sliding direction of the locking slider 2 is provided below the pin fixing plate 5. The second limiting block 202 is embedded in the limiting groove 501 and slides against the inner wall of the limiting groove 501. The limiting groove 501 is used to limit the movement trajectory of the second limiting block 202, thereby constraining the sliding direction of the locking slider 2, ensuring that the locking slider 2 can only slide in a predetermined direction, and improving the accuracy and stability of the operation.

[0036] The locking slider 2 has a hollow structure in the middle, and the diameter of the hollow structure matches the outer diameter of the pin 6, allowing the pin 6 to pass through the hollow structure of the locking slider 2. The middle of the inner wall of the locking slider 2 extends inward to form a limiting platform, which abuts against the fixing rod passing through the first connecting hole 101 and the second connecting hole 502 to achieve axial positioning of the fixing rod. This design ensures that the fixing rod can be precisely positioned after insertion, preventing axial movement during use.

[0037] The fixing and releasing of the fastener is achieved by the sliding of the locking slider 2 between the pin fixing plate 1 and the pin fixing plate 5. When the locking slider 2 slides downward, the inner wall of the locking slider 2 is press-fitted with the fastener or engages with the groove on the fastener through a protrusion, thus fixing the fastener; when the locking slider 2 slides upward, the inner wall of the locking slider 2 is clearance-fitted with the fastener or the protrusion disengages from the groove, thus releasing the fastener. This fixing and releasing mechanism is simple in design, easy to operate, and can quickly lock and release the fastener.

[0038] Control button 3 is used to drive the locking slider 2 to slide. When control button 3 is pressed towards the limit groove 501, the locking slider 2 slides downward against the elastic force of the return spring 4, thereby unlocking the fastener. The elastic force of the return spring 4 is opposite to the pressing direction of control button 3, and is used to push the locking slider 2 back to its original position after the control button 3 is released, thus securing the fastener. This operation method is simple and intuitive; the user only needs to press control button 3 to complete the unlocking operation, and it automatically locks after being released, improving ease of use and safety.

[0039] In a preferred embodiment, the control button 3 and the first limit block 201 are connected by an interference fit. This connection method is simple to install, does not require additional fixing tools, and has good connection strength, which can withstand various forces in daily use.

[0040] In another preferred embodiment, the second limiting block 202 and the locking slider 2 are connected by bolts. This connection method facilitates disassembly and maintenance. At the same time, by adjusting the tightness of the bolts, the relative position between the second limiting block 202 and the locking slider 2 can be finely adjusted, thereby improving the accuracy of the overall structure.

[0041] In use, the user simply presses control button 3, which moves locking slider 2 downwards, releasing the interference fit or locking relationship between the inner wall of locking slider 2 and the fixing part, allowing the fixing part to be freely inserted or removed. Releasing control button 3 causes return spring 4 to push locking slider 2 upwards, restoring the interference fit or locking relationship between the inner wall of locking slider 2 and the fixing part, firmly locking the fixing part and preventing it from moving, thus achieving a stable connection of the handle.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
