Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of fitness equipment, and particularly to a quick replacement buckle for fitness accessories. Background Art
[0002] Fitness is a sports item, such as various calisthenics, aerobic exercises, body-building exercises, and various self-resistance movements. Gymnastics and yoga can enhance strength, flexibility, increase endurance, improve coordination, and control the ability of various parts of the body, thus making the body strong. If you want to achieve the purpose of relieving stress, exercise at least 3 times a week. Fitness equipment is often classified into two major categories: single-function and comprehensive multi-function according to the number of training functions. Commonly used ones include rowing machines, walking machines, treadmills, barbells, and dumbbells.
[0003] There are various intelligent cable fitness machines on the market currently. The link buckles between the cable of the fitness machine and the handle or barbell used by the user are relatively simple lock buckles, such as carabiners or simple spring plug-in buckles. When using a carabiner to connect and the rope moves back and forth quickly, the two carabiners will become loose and tight alternately, resulting in unstable transmitted force and a short empty stroke experience for the customer. When the force is large or the speed is fast, it is easy to get injured. The defects of the existing plug-in spring buckles are as follows: when the user makes movements at different angles, the directions of the forces are different, and the male and female heads of the plug-in spring buckle will relatively produce small displacements, with the risk of unhooking. In view of this, we have proposed a quick replacement buckle for fitness accessories. Summary of the Invention
[0004] (I) Technical Problems to be Solved
[0005] In view of the deficiencies of the prior art, the present invention provides a quick replacement buckle for fitness accessories, which solves the problems mentioned in the above background art.
[0006] (II) Technical Solutions
[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: A quick replacement buckle for fitness accessories, including mounting component one and mounting component two. The mounting component one includes:
[0008] A handle, which is arranged on the top of the mounting component two;
[0009] An inclined block, which is slidably mounted at the bottom of the handle;
[0010] A return spring, which is fixed to the side wall of the inclined block;
[0011] A stop block, which is fixed to the inner wall of the handle.
[0012] Preferably, the second mounting component includes sphere A and sphere B, which are threadedly connected. A limiting sleeve passes through sphere A, and the penetration part of the limiting sleeve fits with sphere A.
[0013] Preferably, a chute is formed on sphere B, which fits with the limiting sleeve. A convex block is fixed on the outer wall of the limiting sleeve, and the outer wall of the convex block fits with a groove formed on sphere A.
[0014] Preferably, a spring groove is formed on sphere B, and a transmission spring is fixed on the inner wall of the spring groove. The top of the transmission spring is fixed to the bottom of the limiting sleeve.
[0015] Preferably, a slider is slidably installed inside the limiting sleeve, and a threaded chute is formed inside the slider.
[0016] Preferably, there are two sets of inclined blocks, and the two sets of inclined blocks are symmetrically arranged with the center line in the vertical direction of the handle as the axis of symmetry.
[0017] Preferably, a fixing column is fixed inside sphere B, and a guide rail is fixed on the outer wall of the fixing column. The guide rail is slidably connected with the threaded chute.
[0018] Preferably, the slider can slide up and down inside the limiting sleeve.
[0019] Preferably, there are two sets of stoppers, and the two sets of stoppers are symmetrically arranged with the center line in the vertical direction of the handle as the axis of symmetry.
[0020] (III) Beneficial effects
[0021] The present invention provides a quick replacement buckle for fitness accessories, which has the following beneficial effects:
[0022] (1) For this quick replacement buckle of fitness accessories, when the inclined block is inserted into the through hole formed on sphere A, the inclined surface of the inclined block is subjected to a squeezing force, which causes the two sets of inclined blocks to approach each other. When the inclined block moves to a position where its inclined surface fits with the top of the slider, the inclined block is no longer subjected to the squeezing force. Then, the return spring can drive the inclined block back to its original position, and the top of the inclined block fits with the protruding part inside the limiting sleeve, which can limit the inclined block and keep the inclined block limited in the limiting sleeve, thus facilitating the operation of the staff.
[0023] (2) For this quick replacement buckle of fitness accessories, when the limitation on the first mounting component and the second mounting component is released, the handle can be pressed down and rotated. Through the cooperation of the limiting sleeve, the threaded chute, the transmission spring, and the guide rail, the slider can move upward to squeeze the two sets of inclined blocks to approach each other, and then the inclined block can be taken out of sphere A, which is convenient for the staff to disassemble the first mounting component and the second mounting component.
[0024] (3) The quick - replacement buckle of this fitness accessory. After the disassembly of the first installation component is completed, by setting the transmission spring, the transmission spring can drive the limit sleeve back to its original position, making the convex block extend into the groove, thereby limiting the limit sleeve and performing the next limiting operation.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0036] Please refer to Figures 1-9, the present invention provides a technical solution: a quick-change buckle for fitness accessories, including a first mounting component 1 and a second mounting component 2. By providing the first mounting component 1 and the second mounting component 2, the quick connection and disassembly of the sports accessories and the tensioning device can be achieved.
[0037] The above-mentioned first mounting component 1 includes a handle 101, an inclined block 102, a return spring 103 and a stop block 104. By providing the handle 101, it is convenient for the user to pick up the first mounting component 1. The inclined block 102 penetrates through the handle 101, and the inclined block 102 is slidably connected to the penetration part of the handle 101. The side wall of the inclined block 102 forms a 60° angle with the top of the inclined block 102. There are two groups of inclined blocks 102, and the two groups of inclined blocks 102 are symmetrically arranged with the center line in the vertical direction of the handle 101 as the axis of symmetry. The return spring 103 is fixed on the surface of the vertical plane of the two groups of inclined blocks 102. By providing the inclined block 102, the first mounting component 1 can be installed. By providing the return spring 103, when the inclined block 102 is not subjected to extrusion pressure, the inclined block 102 can be reset. The bottom of the inner wall of the handle 101 is fixed with a stop block 104. The side wall of the stop block 104 is in contact with the inclined block 102. There are two groups of stop blocks 104, and the two groups of stop blocks 104 are symmetrically arranged with the center line in the vertical direction of the handle 101 as the axis of symmetry. By providing the stop block 104, the position where the inclined block 102 moves to can be restricted, so that the two groups of inclined blocks 102 can approach each other to compress the return spring 103, and the inclined blocks 102 cannot move away from each other to stretch the return spring 103.
[0038] The above-mentioned mounting component 2 includes sphere A202, sphere B203, limiting sleeve 201, transmission spring 204, fixed column 205, slider 207, spring groove 209 and chute 208. The inner wall of the bottom of sphere A202 is threadedly connected to the outer wall of the top of sphere B203. The limiting sleeve 201 is fitted in the chute 208 of sphere B203. The limiting sleeve 201 penetrates through sphere A202, and the top of the limiting sleeve 201 is in contact with the bottom of the handle 101. A fixed convex block 3 is provided on the outer wall of the limiting sleeve 201, and the size of the convex block 3 matches the size of the groove formed on sphere A202. Thus, the limiting sleeve 201 can be limited by the groove and the convex block 3. A slider 207 is slidably installed inside the limiting sleeve 201. The slider 207 can slide up and down inside the limiting sleeve 201. When it is necessary to install the mounting component 1 and the mounting component 2, by holding the handle 101 by the staff, the inclined block 102 can be inserted into sphere A202 through the through hole formed at the top of sphere A202. Then, the inclined surface of the inclined block 102 will squeeze the top of the limiting sleeve 201. Due to the extrusion force on the inclined block 102, the two inclined blocks 102 will approach each other, the return spring 103 will be compressed, and the two inclined blocks 102 will move into the handle 101. When the inclined block 102 is further moved downward and the inclined surface of the inclined block 102 is in contact with the top of the slider 207, the inclined block 102 will no longer be under the extrusion force. Then, the return spring 103 can drive the inclined block 102 back to its original position, and the top of the inclined block 102 will be in contact with the protruding portion inside the limiting sleeve 201, so that the inclined block 102 can be limited and positioned in the limiting sleeve 201, which is convenient for the staff to operate. A threaded chute 4 is formed inside the slider 207. A guide rail 5 is slidably installed on the inner wall of the threaded chute 4. The guide rail 5 is fixed on the outer wall of the fixed column 205. The fixed column 205 is fixed on the inner wall of sphere B203. A transmission spring 204 is fixed at the bottom of the limiting sleeve 201. The transmission spring 204 is fixed on the inner wall of the spring groove 209. The spring groove 209 is formed on sphere B203. By providing the transmission spring 204, when the limiting sleeve 201 is not under the extrusion force, the transmission spring 204 can drive the limiting sleeve 201 back to its original position. When it is necessary to release the limit between the mounting component 1 and the mounting component 2, the handle 101 can be pressed downward, so that the handle 101 squeezes the limiting sleeve 201 to move downward, and the limiting sleeve 201 presses the transmission spring 204 to compress. When the limiting sleeve 201 moves downward in the chute 208, the convex block 3 of the limiting sleeve 201 can move out of the groove formed on sphere A202, and thus the limit on the limiting sleeve 201 can be released. By rotating the handle 101 clockwise, the inclined block 102 drives the limiting sleeve 201 to rotate. Then, the limiting sleeve 201 can drive the slider 207 to rotate. When the limiting sleeve 201 rotates, the transmission spring 204 can be contracted, and the transmission spring 204 is in a state of storing energy.When the limit sleeve 201 drives the slider 207 to rotate forward, the threaded chute 4 can rotate on the guide rail 5. Furthermore, the threaded chute 4 can move upward along the guide rail 5, causing the slider 207 to move upward. The two sliders 207 can squeeze the inclined surfaces of the inclined blocks 102, causing the two inclined blocks 102 to approach each other. The inclined blocks 102 can extend into the handle 101, and then the handle 101 can be pulled to remove the inclined blocks 102 from the sphere A202, facilitating the release of the limit on the mounting component 1 and the mounting component 2. When the inclined blocks 102 are removed from the sphere A202, since the limit sleeve 201 is not under force and the transmission spring 204 is in a contracted state, the transmission spring 204 can drive the limit sleeve 201 to rotate in reverse, causing the slider 207 to move downward on the fixed column 205, returning the slider 207 to its original position. And since the transmission spring 204 is in a compressed state, the limit sleeve 201 can move upward, causing the convex block 3 on the limit sleeve 201 to extend into the groove to limit the limit sleeve 201, and then the next installation operation can be carried out.
[0039] When in operation (or in use), when it is necessary to install the first mounting component 1 and the second mounting component 2, the operator can insert the inclined block 102 into the sphere A202 through the through hole opened at the top of the sphere A202 by holding the handle 101. Then, the inclined surface of the inclined block 102 will squeeze the top of the limiting sleeve 201. Due to the squeezing force on the inclined block 102, the two inclined blocks 102 will move closer to each other, compressing the return spring 103 and causing the two inclined blocks 102 to move into the handle 101. When the inclined block 102 is further moved downward until the inclined surface of the inclined block 102 fits against the top of the slider 207, the inclined block 102 will no longer be under the squeezing force. Then, the return spring 103 can drive the inclined block 102 back to its original position, and the top of the inclined block 102 will fit against the protrusion inside the limiting sleeve 201, thus limiting the inclined block 102 within the limiting sleeve 201, which facilitates the operation of the operator. When it is necessary to release the limitation between the first mounting component 1 and the second mounting component 2, the handle 101 can be pressed downward, causing the handle 101 to squeeze the limiting sleeve 201 downward and compress the transmission spring 204. When the limiting sleeve 201 moves downward within the sliding groove 208, the convex block 3 of the limiting sleeve 201 can move out of the groove opened on the sphere A202, thereby releasing the limitation on the limiting sleeve 201. By rotating the handle 101 clockwise, the inclined block 102 drives the limiting sleeve 201 to rotate. Then, the limiting sleeve 201 can drive the slider 207 to rotate. When the limiting sleeve 201 rotates, the transmission spring 204 can contract and be in a state of storing energy. When the limiting sleeve 201 drives the slider 207 to rotate clockwise, the threaded sliding groove 4 can rotate on the guide rail 5, and then the threaded sliding groove 4 can move upward along the guide rail 5, causing the slider 207 to move upward. The two sliders 207 can squeeze the inclined surface of the inclined block 102, causing the two inclined blocks 102 to move closer to each other and the inclined block 102 to extend into the handle 101. Then, the handle 101 can be pulled to remove the inclined block 102 from the sphere A202, facilitating the release of the limitation between the first mounting component 1 and the second mounting component 2.
