[0001] This invention relates to the field of building accessories technology, and in particular to a convenient snap-fit ​​fastener. Background Technology

[0002] Existing steel pipe fasteners for construction include cross-shaped right-angle fasteners, corner fasteners, and butt-joint fasteners. These fasteners hinge the inner fastener seat and outer fastener cover together via a hinge shaft, and the inner fastener seat and outer fastener cover are connected by bolts, nuts, etc. To ensure the smooth completion of the project, the fasteners must have sufficient strength and durability; in addition, the fasteners need to have few parts to facilitate quick assembly. The existing fastener connection method is to tighten and clamp by threading, which requires the use of auxiliary tools during operation. This results in numerous parts, inconvenient installation, and reduced user efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide a convenient quick-release fastener. The fastener has a simple structure, and in use, simply pressing the handle to lock the hook and the spring-loaded device together is sufficient; no screws need to be tightened, thus improving work efficiency. The entire fastener is a single unit, eliminating the need for multiple parts and making it easy to carry.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0005] A convenient quick-release fastener includes a bracket base. One end of the bracket base is rotatably connected to a handle and a fastening element. The handle is located outside the fastening element to drive the fastening element to press down. The other end of the bracket base has a spring-loaded component on its inner side. The spring-loaded component includes a slider that slides with the bracket base. The slider is connected to the bracket base via a spring. The handle has a hook. Pressing down the handle causes the hook to push the slider to retract. After the hook passes the slider, the slider extends to lock the hook.

[0006] As a further implementation, the support base is U-shaped, with a space in the middle for accommodating the pipe fittings.

[0007] As a further implementation, the handle is rotatably connected to the bracket base via a first positioning pin.

[0008] As a further implementation, the fastening element is rotatably connected to the bracket base via a second locating pin.

[0009] As a further implementation, the second locating pin is provided with a spring-loaded element on its periphery to push the fastening element outward.

[0010] As a further implementation, the rebound assembly includes a sleeve disposed inside the support base, with one end of a spring connected to the inner end face of the sleeve and the other end of the spring connected to a slider.

[0011] As a further implementation, the top of the front end of the slider is sloping, and the bottom is provided with a slot, which cooperates with the hook.

[0012] As a further implementation, the bottom surface of the hook end is also a slope.

[0013] As a further implementation, a spring-loaded component is also provided on the periphery of the first positioning pin.

[0014] As a further implementation, the rebound element is a return spring.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The fastener structure of the present invention is simple. In use, simply press the handle to lock the hook and the spring-loaded device together, without the need to tighten screws, thus improving work efficiency. The entire fastener structure is an integral structure, requiring no multiple parts to work together, making it easy to carry. By using the handle to drive the pressing component down and cooperate with the spring-loaded device, the supporting force of the pressed pipe and the spring-loaded component tend to push the pressing component and the handle open. The hook and the spring-loaded component are locked together, allowing the spring-loaded component and the spring-loaded device to work together to further achieve the fastening effect of the fastener.

[0017] 2. The top of the slider of the present invention is a slope. The slider is engaged with the hook through a slot. When the handle is pressed down, the hook first engages with the slope of the slider, which facilitates pushing the slider into the sleeve first. After the hook passes, the slider extends out and locks the hook. Attached Figure Description

[0023] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0024] Example 1

[0025] In a typical embodiment of the present invention, reference is made to Figures 1-2 As shown, a convenient quick-release fastener includes a bracket base 1, a handle 3, and a fastening element 4. The bracket base 1 is provided with a spring-loaded component 2, which, when the handle pushes down the fastening element 4, uses a slider 23 to press against the hook 31 on the handle 3 to prevent the handle from opening.

[0026] like Figure 1 As shown, the bracket base 1 is U-shaped, with a space in the middle for accommodating pipe fittings and other clamping structures. One end of the top of the bracket base 1 is rotatably connected to a handle 3 and a clamping member 4, wherein the clamping member 4 is located inside the handle 3, and the outer surface shape of the clamping member 4 is adapted to the inner surface shape of the handle 3.

[0027] The handle 3 is rotatably connected to the bracket base via the first positioning pin 6, and the fastening member 4 is rotatably connected to the bracket base via the second positioning pin 7. The length of the handle 3 is greater than the length of the fastening member. When the handle 3 is pressed by the end of the handle 3, the handle 3 drives the fastening member 4 to rotate relative to the top end of the bracket base 1, close to the receiving space, and thus press and fix the structure.

[0028] like Figure 1 As shown, a spring-loaded component 2 is horizontally provided inside the other end of the top of the bracket base 1, and the spring-loaded component 2 connects to the inner side of the bracket base 1. Figure 2 As shown, the rebound assembly 2 includes a sleeve 21 disposed inside the bracket base 1. One end of the spring 22 is connected to the inner end face of the sleeve 21, and the other end of the spring 22 is connected to the slider. The slider 23 is slidably engaged with the bracket base 1.

[0029] In its natural state, spring 22 pushes out slider 23, causing slider 23 to extend beyond the inner side of the support base 1. For example... Figure 1 As shown, a hook 31 is provided at the middle position of the bottom of the handle 3. When the handle 3 is pressed down, the hook 31 is located at the position of the spring-loaded component 2. Pressing down the handle 3 causes the hook 31 to push the slider 23 to retract. After the hook 31 passes the slider 23, the slider 23 extends to lock the hook 31.

[0030] like Figure 2As shown, the top of the front end of the slider 23 is sloped, and the bottom is provided with a groove 24. The groove 24 engages with the hook. To better lock the hook, the bottom surface of the groove 24 is flat, ensuring that the hook 31 will not detach from the slider. The bottom surface of the end of the hook 31 is also sloped to better engage with the sloped front end of the slider. When the handle is pressed down, the slider is easily pushed into the sleeve first. After the hook passes, the slider extends and locks the hook.

[0031] like Figure 1 As shown, the second positioning pin 7 has a spring-loaded part 5 on its periphery to push the clamping part 4 to open outward. When the hook 31 disengages from the slider 23, under the action of the spring-loaded part 5, the clamping part 4 drives the handle 3 to rotate relative to the bracket base 1, which has the tendency to cause the handle 3 and the clamping part 4 to open. The first positioning pin 6 can also be provided with a spring-loaded part, which is a return spring, such as a leaf spring.

[0032] In this embodiment, the handle drives the clamping component to press down and cooperates with the spring-loaded device. The supporting force of the clamped pipe and the spring-loaded component have a tendency to push the clamping component and the handle to open. The hook and the spring-loaded component are locked together, so that the spring-loaded component and the spring-loaded device can work together to further achieve the fastening effect of the fastener.

[0033] The fastener structure in this embodiment is simple. When in use, simply press the handle to lock the hook and the spring-loaded device together. There is no need to tighten the screws, which improves work efficiency. The entire fastener structure is a single piece, which does not require multiple parts to work together and is easy to carry.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
