Description

Technical Field

[0001] This invention relates to the field of locking technology, and more particularly to a quick self-locking device. Background Technology

[0002] A hook is a device that connects and fixes objects in the air by means of its own connection, and hangs them in the air. In daily life, hooks have become very practical and convenient household items. Currently, hooks usually use compression to fix ropes. However, this type of hook cannot effectively lock ropes that are made of hard and smooth materials, resulting in the rope slipping off, which is not safe and has low work efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a quick self-locking device that enhances the safety of rope use through the cooperation of clamping protrusions, top rods, and safety buckles, thereby solving the problems of low safety and low work efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a quick self-locking device, comprising a self-locking device body, the self-locking device body having a working space, a hook disposed on the self-locking device body, an anti-disengagement buckle disposed on the self-locking device body and cooperating with the hook, further comprising: a clamping protrusion rotatably disposed in the working space and capable of clamping the rope by cooperating with the side wall of the working space when rotated by a rope; a top rod slidably disposed in the clamping protrusion and capable of pressing and clamping the rope at the side wall of the working space when the rope is pulled in the forward direction; and a safety ring disposed on the clamping protrusion in the axial extension direction of the top rod.

[0005] Preferably, the clamping protrusion is provided with the rope guard.

[0006] Preferably, a torsion spring groove is provided inside the clamping protrusion, and a torsion spring is provided between the torsion spring groove and the self-locking device body.

[0007] Preferably, a guide angle is provided inside the self-locking device body.

[0008] Preferably, the self-locking device body has a rope threading hole, which is connected to the working space.

[0009] Preferably, the side wall of the workspace is provided with anti-slip texture one, the anti-slip texture one is wavy, and the clamping protrusion is provided with anti-slip texture two that can cooperate with the wavy anti-slip texture one.

[0010] Preferably, a stabilizing groove is provided on one side wall of the workspace, and the rope guard slides in the stabilizing groove.

[0011] Preferably, the self-locking device body has a compression groove, the push rod slides in the compression groove, the push rod includes a push rod, a compression cap disposed on the push rod near the end of the safety ring, and a clamping block disposed on the end away from the safety ring, the clamping block is slidably connected to the compression groove, a support block is fixedly disposed in the compression groove, the support block is slidably connected to the push rod, and a spring is connected between the support block and the clamping block.

[0012] Preferably, the end of the clamping block away from the extrusion cap mates with the anti-slip texture—a concave-convex surface—and its shape is wavy.

[0013] The beneficial effects of this invention are as follows:

[0014] (1) When the rope is pulled down, the rope is in a vertical state. The rope can be driven by the squeezing force of the rope to slide in the clamping protrusion, thereby clamping the rope a second time, further increasing the squeezing force on the rope, and positioning the rope more securely. This avoids the situation where the clamping force is insufficient when clamping a smooth and hard rope, causing the rope to slip and affecting the user's safety.

[0015] (2) The present invention provides a safety ring at the right end of the top rod, which can limit the range of motion of the rope located there, and prevent the rope from being unable to effectively exert the tension of the rope at the end of the top rod due to a series of external factors such as wind direction and change of pulling direction when the rope is pulled down at high intensity. In addition, the force range at the end of the top rod is small, which makes it easy for the rope to separate from the top rod 5, resulting in reduced safety and making it difficult to guarantee the safety of the user.

[0016] (3) The present invention can increase the friction between the anti-slip texture 1 and the rope by setting the wavy anti-slip texture 2. When the two are squeezed together, the rope can be further squeezed to make the rope and the wavy texture 1 abut against each other. At the same time, the waves of the anti-slip texture 1 and the anti-slip texture 2 cooperate with each other. When the rope is squeezed, the contact area between the rope and the squeezing protrusion can be increased, thereby increasing the friction between the rope and the anti-slip texture 1 and the anti-slip texture 2, and improving the clamping effect on the rope.

[0017] In summary, the present invention has the advantages of increasing rope safety, improving rope tightness, and increasing service life. Attached Figure Description

[0024] Example 1

[0025] Figures 1-4 The illustration schematically shows an easy-to-use centrifugal concentrator according to one embodiment of the present invention.

[0026] like Figure 1-3 As shown, this embodiment provides a quick self-locking device, including a self-locking device body 1, a working space 11, a hook 2 disposed on the self-locking device body 1, an anti-disengagement buckle 21 disposed on the self-locking device body 1 and cooperating with the hook 2, and also including a clamping protrusion 4 that is rotatably disposed in the working space 11 and can cooperate with the side wall of the working space 11 to clamp the rope 3 when it rotates under the drive of the rope 3.

[0027] The self-locking device body 1 is provided with an anti-disengagement mounting block 51. One end of the anti-disengagement buckle 51 is movably installed on the self-locking device body 1, and the other end abuts against the hook 2 to close the notch of the hook 2. When the rope 3 is pulled counterclockwise, the rope 3 drives the clamping protrusion 4 to rotate by its own friction. The rotation of the clamping protrusion 4 squeezes the rope 3 to the side wall of the working space 11 for limitation. When the rope 3 is pulled clockwise, it can increase the distance between the clamping protrusion 4 and the left side wall of the working space 11, so the rope 3 can be easily pulled between the two.

[0028] The sliding mechanism inside the clamping protrusion 4 can press the top rod 4, which is located on the inner wall of the workspace 11, to press the rope 3 when the rope 3 is pulled in the forward direction.

[0029] The rope 3 is slidably connected to the clamping protrusion 4. When the rope 3 is pulled down, the rope 3 is in a vertical state. The squeezing force of the rope 3 can drive the top rod 5 to slide in the clamping protrusion 4, thereby clamping the rope a second time and further increasing the squeezing force on the rope. This provides a more secure positioning of the rope 3 and avoids the situation where the clamping force is insufficient when clamping the smooth and hard rope 3, causing the rope 3 to slip and affecting the user's safety.

[0030] A safety ring 41 is provided on the clamping protrusion 4 in the axial extension direction of the push rod 4;

[0031] A safety ring 41 is installed at the right end of the top rod 5 to limit the range of motion of the rope 3 located there. This prevents the rope 3 from being unable to effectively apply the tension of the rope 3 to the end of the top rod 5 due to a series of external factors such as changes in wind direction and pulling direction when the rope 3 is pulled down at high intensity. In addition, the force range at the end of the top rod 5 is small, which makes it easy for the rope 3 to separate from the top rod 5, resulting in reduced safety and making it difficult to guarantee the safety of the user.

[0032] To further enhance the safety effect of the safety ring 41, the aperture of the safety ring 41 should not be set too large. When the push rod 5 is in the initial state, the distance between the push rod 5 and the safety ring 41 is the distance of one rope 3.

[0033] Combination Figure 3 As shown, a rope guard 42 is provided on the clamping protrusion 4.

[0034] In this embodiment, when the rope 3 moves in the working space 11, in order to prevent the clamping protrusion 4 from disengaging from the rope 3 clamped at the side wall of the working space 11 and causing the clamping to fail, a rope guard 42 is provided on the clamping protrusion 4 to further improve the locking effect of the rope 3, thereby limiting the rope 3 between the clamping protrusion 4 and the working space 11. The rope guard 42 can effectively prevent the rope 3 from derailing, further increasing the safety of the rope 3 during use and greatly improving safety.

[0035] Combination Figure 3 As shown, a torsion spring groove 6 is provided inside the clamping protrusion 4, and a torsion spring 61 is provided between the torsion spring groove 6 and the self-locking device body 1.

[0036] In this embodiment, the two ends of the torsion spring 61 are connected to the torsion spring groove 6 and the front side wall of the working space, respectively. When the clamping protrusion 4 rotates, the torsion spring 61 stores force. When the clamping protrusion 4 loses external force, the torsion spring 61 releases its elastic force to drive the clamping protrusion 4 to reset.

[0037] Combination Figure 3 As shown, a guide angle 12 is provided inside the self-locking device body 1.

[0038] In this embodiment, when threading the rope inside the self-locking device body 1, the presence of the guide angle 12 can guide the rope 3 from the right side of the working space 11 and out along the arc of the guide angle from the front side of the working space 11. Then, the safety ring 41 is pushed to drive the clamping protrusion 4 to rotate, and the rope 3 is placed between the clamping protrusion 4 and the left side wall of the working space 11.

[0039] Combination Figure 3 As shown, the self-locking device body 1 has a rope hole 13, which is connected to the working space 11.

[0040] In this embodiment, the present invention has multiple rope threading methods and various usage methods. The rope can be threaded from the right side of the workspace 11, or the rope 3 can be directly threaded through the rope threading hole 13 and out through the front side of the workspace 11. Then, the safety ring 41 is pushed to drive the clamping protrusion 4 to rotate, and the rope 3 is placed between the clamping protrusion 4 and the left side wall of the workspace 11.

[0041] Combination Figure 1 As shown, the side wall of the workspace 11 is provided with anti-slip texture 14, which is wavy. The clamping protrusion 4 is provided with anti-slip texture 2 15 that can cooperate with the wavy anti-slip texture 14.

[0042] In this embodiment, the wavy anti-slip texture 14 can increase the friction between the rope 3 and the anti-slip texture 2 15. When the two are used together to compress the rope 3, the rope 3 can be further brought into contact with the wavy texture. At the same time, the waves of the anti-slip texture 14 and the anti-slip texture 2 15 work together to increase the contact area between the rope 3 and the compression protrusion 4 when the rope 3 is compressed, thereby increasing the friction between the rope 3 and the anti-slip texture 14 and the anti-slip texture 2 15 and improving the clamping effect on the rope 3.

[0043] Combination Figure 1 , 4 As shown, a stabilizing groove 111 is provided on one side wall of the workspace 11, and the rope guard 42 slides in the stabilizing groove 111.

[0044] In this embodiment, the rope guard 42 slides in the stabilizing groove 111. During high-intensity use, the clamping protrusion 4 is prone to shaking. Frequent shaking will affect the service life. Sliding the rope guard 42 in the stabilizing groove 111 can reduce the shaking of the clamping protrusion 4 and increase stability. When the rope 3 shakes and the force is transmitted to the rope guard 42, the rope guard 42 is subjected to force more evenly, avoiding the application of all the force to the clamping protrusion 4 and the self-locking device body 1.

[0045] Combination Figure 3 As shown, the self-locking device body 1 has a compression groove 43 inside, and the push rod 5 slides in the compression groove 43. The push rod 5 includes a push rod 51, a compression cap 52 set on the push rod 51 near the safety ring 41, and a clamping block 53 set on the end away from the safety ring 41. The clamping block 53 is slidably connected to the compression groove 43. A support block 54 is fixedly set in the compression groove 43. The support block 54 is slidably connected to the push rod 51. A spring is connected between the support block 54 and the clamping block 53.

[0046] In this embodiment, a compression cap 52 is provided at the end of the push rod 51 near the safety ring 41, which can increase the contact area with the rope 3, thereby making the force on the compression cap 52 more even. At the same time, it can ensure that the force of the rope 3 can be applied to the push rod 51 through the compression cap 52 to the maximum extent. The spring is in a natural state in the initial state. When the compression cap 52 acts on the push rod 51, the push rod 51 drives the compression block 53 to clamp and limit the rope 3. When the compression cap 52 loses the pushing force of the rope 3, the compression block 53 returns to the initial position under the tension of the spring, which is convenient for the next use.

[0047] Combination Figure 3 As shown, the end of the clamping block 55 away from the extrusion cap 52 is engaged with the anti-slip texture 14, which has a wavy shape.

[0048] In this embodiment, the end of the clamping block 55 near the left side wall of the workspace 11 is wavy, which can cooperate with the wavy shape on one side wall of the workspace 11 to clamp the rope.

[0049] Work steps

[0050] In use, rope 3 is inserted along the right side of the workspace 11 and exits from the front of the workspace 11 along the arc of the guide angle. The right end of rope 3 is then passed downwards through the safety ring 41. Pushing the safety ring 41 causes the clamping protrusion 4 to rotate. Rope 3 is placed between the clamping protrusion 4 and the left side wall of the workspace 11. When the right end of rope 3 is pulled, the friction of rope 3 causes the clamping protrusion 4 to rotate clockwise, thus pressing rope 3 firmly between anti-slip texture 14 and anti-slip texture 15. Simultaneously, as rope 3 moves downwards, it presses down on the compression cap 52, which in turn moves the push rod 51. The spring is initially in its natural state. When the compression cap 52 acts on the push rod 51, the push rod 51 moves the compression block. 53 clamps and limits the rope 3. When the squeezing cap 52 loses the thrust of the rope 3, the squeezing block 53 returns to its initial position under the tension of the spring, making it easy to use next time. When the left end of the rope 3 is pulled, the clamping protrusion 4 rotates counterclockwise in the opposite direction. At this time, the rope 3 loses the clamping force and can continue to be pulled down. When lifting light items, the rope 3 can also be directly inserted into the rope hole 13 and then passed between the anti-slip pattern 14 and the anti-slip pattern 2 15. When the rope 3 enters between the anti-slip pattern 14 and the anti-slip pattern 2 15, the safety ring 41 is turned by hand to rotate the clamping protrusion 4, so that the clamping protrusion 4 rotates away from the anti-slip pattern 14, making it easier for the rope 3 to pass between the anti-slip pattern 14 and the anti-slip pattern 2 15.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
