Description

Technical Field

[0001] The present invention relates to the technical field of hanging ring tools, in particular to a detachable U-shaped hanging ring and its installation and disassembly method. Background Art

[0002] The U-shaped hanging ring is generally installed through the installation shafts at both ends. In some application scenarios, the U-shaped hanging ring needs to be deflected by a certain angle to facilitate sufficient hanging space for the hanging object. However, the installation angle adjustment of the existing U-shaped hanging ring is not flexible enough. Especially when disassembling and installing, the installation angle cannot be adjusted synchronously, which brings inconvenience to the operation.

[0003] In addition, the existing installation angles can generally only be adjusted to a limited number of set angles and cannot be adjusted arbitrarily; some adopt the method of squeezing and fixing the installation shaft to achieve the adjustment of the installation shaft at any angle. However, in actual use, if the squeezing force on the installation shaft is too small, the installation shaft often deflects due to the excessive gravity of the hanging heavy object. If the squeezing force on the installation shaft is too large, it is easy to cause a large pressure on the contact part of the installation shaft and generate a large torsional deflection force on the installation shaft after hanging the object, thereby affecting the service life of the U-shaped hanging ring.

Detailed implementation manners

[0032] To make the objectives, features and advantages of the present invention more obvious and understandable, the following provides a detailed description of the specific implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0033] In the following description, many specific details are set forth to facilitate a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0034] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other with other embodiments. Embodiment

[0035] Refer to Figures 1 - 3, which is the first embodiment of the present invention. This embodiment provides a detachable U-shaped hanging ring, which includes: a fixing component 100, a hanging ring body 200, and an anti-slip component 300. The installation shaft 201 of the hanging ring body 200 is tightly fixed by setting the fixing component 100. The hanging ring body 200 is used for hanging heavy objects. The anti-slip component 300 is set to prevent the installation shaft 201 of the hanging ring body 200 from deflecting at an angle due to the force applied.

[0036] Specifically, the fixing component 100 includes a mounting base 101, a supporting portion 102 provided on the top of the mounting base 101 and adapted to the outer shape of the installation shaft 201, and a pressing portion 103 provided on one side of the mounting base 101 and adapted to the installation shaft 201. The supporting portion 102 is set to carry the installation shaft 201 to be installed, and the pressing portion 103 is used for extrusion and fixation.

[0037] Furthermore, an installation shaft 201 is provided at the end of the hanging ring body 200, and a limiting plate 202 is provided at the end of the installation shaft 201. The limiting plate 202 can prevent the installation shaft 201 from slipping axially from the supporting portion 102 and plays an axial limiting role. The anti-slip component 300 is provided on one side of the supporting portion 102 and includes an anti-slip pad 301 provided on the side of the supporting portion 102 close to the installation shaft 201. The anti-slip pad 301 is made of a flexible material, and the friction coefficient of the surface of the anti-slip pad 301 is greater than that of the surface of the support plate 302b. Anti-slip protrusions 203 adapted to the anti-slip pad 301 are axially provided on the surface of the installation shaft. The anti-slip protrusions 203 are made of a solid material and can cooperate with the anti-slip pad 301 to increase the friction force between the two, playing a role in preventing the installation shaft 201 from deflecting at an angle.

[0038] Among them, the pressing portion 103 includes a connecting seat 103a provided on one side of the mounting base 101, a guiding rod 103b vertically provided at the top of the connecting seat 103a, a pressing block 103c slidably connected to one side of the guiding rod 103b, a tightening rod guiding groove 103d longitudinally penetrating the surface of the pressing block 103c, and a tightening rod 103e provided at the top of the connecting seat 103a and adapted to the tightening rod guiding groove 103d. A nut 103f adapted to the tightening rod guiding groove 103d is threadedly connected to the surface of the tightening rod 103e, and the bottom of the pressing block 103c is a flat surface.

[0039] Preferably, a limiting block 103b-1 is provided at the top of the guiding rod 103b. The height of the bottom of the limiting block 103b-1 is greater than the height of the top of the tightening rod 103e, and the distance between the bottom of the limiting block 103b-1 and the top of the tightening rod 103e is adapted to the thickness of the pressing block 103c. The guiding rod 103b is cylindrical in shape, and a telescopic torsion spring 103b-2 is nested on the surface of the guiding rod 103b. Two ends of the telescopic torsion spring 103b-2 are respectively connected with the connecting seat 103a and the pressing block 103c. When the tightening rod guiding groove 103d of the pressing block 103c is higher than the top end of the tightening rod 103e, it automatically rotates around the guiding rod 103b by the torsion force of the telescopic torsion spring 103b-2. The top of the pressing block 103c is blocked by the limiting block 103b-1 to prevent it from popping out and vibrating under the action of inertia. After the pressing block 103c rotates 90° around the guiding rod 103b, the pressing block 103c will be supported by the elastic force of the telescopic torsion spring 103b-2, so that there is enough space to remove the mounting shaft 201.

[0040] Installation process: When installing the hanging ring body 200, first adjust the installation angle of the hanging ring body 200 relative to the mounting shaft 201. After the installation angle is determined, place the mounting shaft 201 to be installed on the surface of the supporting part 102 so that the anti-slip protrusion 203 contacts the anti-slip pad 301. Then rotate the pressing block 103c through the guiding rod 103b. The rotation of the pressing block 103c will drive the telescopic torsion spring 103b-2 to twist, and at the same time drive the tightening rod guiding groove 103d to rotate until it aligns with the tightening rod 103e. Then press down the pressing block 103c and fasten it with the nut 103f. The process of the nut 103f sliding down the thread drives the pressing block 103c to move downward and compresses the telescopic torsion spring 103b-2 until the bottom of the pressing block 103c squeezes the mounting shaft 201 tightly. The anti-slip protrusion 203 at the bottom of the mounting shaft 201 squeezes the anti-slip pad 301 to deform, thereby increasing the contact area and thus increasing the frictional resistance, and further increasing the frictional resistance when the mounting shaft 201 has a tendency to rotate, so as to reduce the influence of slippage. The other mounting shaft 201 adopts the same installation method. After both ends of the mounting shaft 201 are fixed, the hanging ring body 200 can be mounted and used.

[0041] When in use for hanging, the force exerted by the hanging object on the hanging ring body 200 causes a tendency of rotation between the mounting shaft 201 and the surface of the supporting part 102. The large frictional force between the anti-slip protrusion 203 and the anti-slip pad 301 blocks the rotation, so that the mounting shaft 201 maintains the installation angle for use.

[0042] Disassembly process: When disassembly is required, reverse the nut 103f until it is removed. During the upward movement of the nut 103f, the pressing block 103c also moves upward under the elastic force of the telescopic torsion spring 103b-2. When the tightening rod guide groove 103d is higher than the top of the tightening rod 103e, it automatically rotates around the guide rod 103b under the torsional force of the telescopic torsion spring 103b-2. The top of the pressing block 103c is blocked by the limiting block 103b-1 to prevent it from popping out and vibrating under the action of inertia. After the pressing block 103c rotates around the guide rod 103b, there is enough space to remove the mounting shaft 201, and the mounting angle of the mounting shaft 201 does not affect the disassembly. Embodiment

[0043] Refer to Figures 4 - 7 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a fixed support member 302 and a movable support member 303, which solves the problem that the angle deflection occurs at the mounting shaft due to the excessive gravity of the hanging heavy object in the extrusion-fixed installation.

[0044] Specifically, the support portion 102 includes a support base 102a connected to the adjustment portion 201, and support inclined surfaces 102b symmetrically arranged on the top of the support base 102a; the anti-slip assembly 300 further includes a fixed support member 302 arranged on one side of the support inclined surface 102b, and a movable support member 303 arranged on one side of the support inclined surface 102b and higher than the surface of the fixed support member 302. The support plate 302b made of rigid material and the anti-slip pad 301 made of flexible material are both subjected to the extrusion force of the mounting shaft 201, and at this time, the maximum static friction force between the mounting shaft 201 and the anti-slip pad 301 is greater than the maximum static friction force between the mounting shaft 201 and the support plate 302b.

[0045] Furthermore, the fixed support member 302 includes a mounting frame 302a embedded in the top of the support inclined surface 102b, and a support plate 302b arranged on one side of the mounting frame 302a; the movable support member 303 includes a groove 303a formed by penetrating the mounting frame 302a and recessing inward from the support inclined surface 102b, a guide groove 303b opened on one side of the mounting frame 302a, and a connecting frame 303c slidably connected to one side of the guide groove 303b. When the pressing block 103c moves downward to press the mounting shaft 201, the anti-slip pad 301 made of flexible material is squeezed and deformed until the oval tightening pressure wheel 304e is squeezed. After the tightening pressure wheel 304e is stressed, it will adaptively rotate a certain angle through the rotating shaft 304b and then keep the position of the shortest distance from the center of the tightening pressure wheel 304e to its surface in contact with the stress point of the mounting shaft 201. After being pressed, one side of the hollow groove 304d of the anti-slip pad 301 is supported by the tightening pressure wheel 304e; The anti-slip pad 301 is installed on one side of the connecting frame 303c and protrudes above the surface of the support plate 302b. A tightening member 304 adapted to the anti-slip pad 301 is provided in the groove 303a.

[0046] Among them, the tightening member 304 includes a rack 304a provided on the side of the connecting frame 303c close to the guiding groove 303b, a rotating shaft 304b rotatably connected in the groove 303a, a tightening gear 304c fixedly connected to one side of the rotating shaft 304b and adapted to the rack 304a, a hollow groove 304d formed by recessing from the bottom of the connecting frame 303c into the anti-slip pad 301, and a tightening pressing wheel 304e fixedly connected to one side of the rotating shaft 304b and adapted to the hollow groove 304d; The rotating shaft 304b and the groove 303a are connected by a torsion spring to form a reset structure. The vertical cross-section of the tightening pressing wheel 304e is elliptical, and the position of the shortest distance from the rotation center of the tightening pressing wheel 304e to its surface is tangent to the plane where the support plate 302b is located. By increasing the pressing on the anti-slip pad 301 on one side of the hollow groove 304d, and the larger the rotation angle of the tightening gear 304c, the more prominent the pressing effect. The greater the pressing force on the anti-slip pad 301 will increase the maximum static friction force between the anti-slip pad 301 and the mounting shaft 201, thereby inhibiting the rotational slippage of the mounting shaft 201.

[0047] Preferably, multiple groups of the support plates 302b and the anti-slip pads 301 are provided, and the multiple groups of support plates 302b and anti-slip pads 301 are distributed at intervals. This makes the force between the mounting shaft 201, the support plates 302b, and the anti-slip pads 301 stable.

[0048] The remaining structure is the same as that of Embodiment 1.

[0049] Installation process of the mounting shaft 201: When the mounting shaft 201 is placed on the support base 102a, the bottom of the mounting shaft 201 first contacts the anti-slip pad 301 with a higher surface. When the pressing block 103c moves downward to press the mounting shaft 201, the anti-slip pad 301 made of a flexible material is squeezed and deformed until the elliptical tightening pressing wheel 304e is stressed and squeezed. After the tightening pressing wheel 304e is stressed, it will adaptively rotate a certain angle through the rotating shaft 304b and then keep the position of the shortest distance from the center of the tightening pressing wheel 304e to its surface in contact with the force application point of the mounting shaft 201. After pressing, one side of the hollow groove 304d of the anti-slip pad 301 is supported by the tightening pressing wheel 304e. Both the support plate 302b made of a rigid material and the anti-slip pad 301 made of a flexible material are subjected to the extrusion force of the mounting shaft 201, and at this time, the maximum static friction force between the mounting shaft 201 and the anti-slip pad 301 is greater than the maximum static friction force between the mounting shaft 201 and the support plate 302b.

[0050] When in use, when the installation shaft 201 has a tendency to rotate due to the hanging of a heavy object, if the rotational force of the installation shaft 201 is greater than the maximum static friction force between the installation shaft 201 and the support plate 302b, the installation shaft 201 will apply a force to the anti-slip pad 301, driving the anti-slip pad 301 and the connecting frame 303c to move along the direction of the guiding groove 303b through friction. The movement of the connecting frame 303c will drive the tightening gear 304c to rotate through the rack 304a, and the rotation of the tightening gear 304c will drive the tightening pressure wheel 304e to rotate synchronously through the rotating shaft 304b. Since in the initial state, the elliptical tightening gear 304c contacts the force application point of the installation shaft 201 at the position of the shortest distance from the rotation center to its surface, after the tightening gear 304c rotates, the distance between the rotation center and the contact point between the surface of the tightening gear 304c and the force application point of the installation shaft 201 will gradually increase, thereby increasing the pressing force on the anti-slip pad 301 through one side of the hollow groove 304d. Moreover, the larger the rotation angle of the tightening gear 304c, the more prominent the pressing effect, and the greater the pressing force on the anti-slip pad 301 will increase the maximum static friction force between the anti-slip pad 301 and the installation shaft 201, thereby inhibiting the rotational slippage of the installation shaft 201. At the same time, after the tightening gear 304c rotates, it supports the contact force-bearing part of the installation shaft 201, improving the hanging weight stability. Embodiment

[0051] Refer to Figures 8 - 11 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a blocking part 305 to further increase the blocking force when the installation shaft 201 rotates and slips.

[0052] Specifically, the anti-slip assembly 300 further includes a blocking part 305 arranged inside the support seat 102a and connected to the connecting frame 303c. The blocking part 305 includes a connecting groove 305a opened inside the support seat 102a and communicating with the two side grooves 303a, a blocking member 305b arranged in the connecting groove 305a, and two groups of connecting rods 305c arranged between the two side connecting frames 303c and the blocking member 305b. The two side connecting rods 305c are respectively connected to the gear ring 305b-2 and the internal gear 305b-4.

[0053] Furthermore, the two groups of connecting rods 305c are respectively rotatably connected to the opposite sides of the blocking member 305b, and the connecting rods 305c are rotatably connected to the connecting frame 303c. The gear ring 305b-2 drives the internal gear 305b-4 to have a tendency to rotate in the opposite direction through the planetary gear 305b-5, thereby pulling the connecting frame 303c on the other side through the connecting rod 305c connected to the internal gear 305b-4 to have a rotational tendency opposite to the rotation direction of the installation shaft 201.

[0054] Among them, the blocking member 305b includes a connecting sleeve 305b-1 fixedly connected to the inner wall of the connecting groove 305a, a gear ring 305b-2 rotatably connected to one side of the connecting sleeve 305b-1 and connected to one group of connecting rods 305c, a rotating shaft 305b-3 rotatably connected to the inner side of the connecting sleeve 305b-1, an internal gear 305b-4 provided on the surface of the rotating shaft 305b-3, a planetary gear 305b-5 rotatably connected to the inner wall of the connecting sleeve 305b-1 and meshing with the gear ring 305b-2 and the internal gear 305b-4 respectively, and a connecting block 305b-6 fixedly connected to one side of the rotating shaft 305b-3 and adapted to the other group of connecting rods 305c. In this embodiment, an avoidance groove 305b-7 adapted to the connecting block 305b-6 is provided on one side of the connecting sleeve 305b-1 close to the connecting block 305b-6, and the size of the avoidance groove 305b-7 is adapted to the rotation angle range of the connecting block 305b-6. By arranging the gear ring 305b-2, the internal gear 305b-4 and the planetary gear 305b-5 to form a planetary gear set, when the gear ring 305b-2 rotates, it will drive the internal gear 305b-4 to rotate in the opposite direction, and vice versa, when the internal gear 305b-4 rotates, it will also drive the gear ring 305b-2 to rotate in the opposite direction.

[0055] The remaining structures are the same as those in Embodiment 2.

[0056] Working principle: The rotational tendency of the mounting shaft 201 in a certain direction gives the acting forces on the two-sided anti-slip pads 301 in directions exactly opposite to the two-sided support inclined surfaces 102b. That is, when one-sided anti-slip pad 301 is subjected to a downward force along the current support inclined surface 102b, the other-sided anti-slip pad 301 is subjected to an upward force along the current support inclined surface 102b; when one-sided anti-slip pad 301 is subjected to a downward force along the current support inclined surface 102b, the connecting frame 303c on this side will move downward along the direction of the guiding groove 303b, and the connecting rod 305c on this side exerts a thrust on the gear ring 305b-2 connected thereto, so that the gear ring 305b-2 generates a rotational tendency in the same direction as the rotation direction of the mounting shaft 201, and the gear ring 305b-2 drives the internal gear 305b-4 to have a rotational tendency in the opposite direction through the planetary gear 305b-5, so as to pull the connecting frame 303c on the other side through the connecting rod 305c connected to the internal gear 305b-4 to have a rotational tendency opposite to the rotation direction of the mounting shaft 201, thereby restricting the movement of the connecting frame 303c and further inhibiting the rotational slippage of the mounting shaft 201.
