Description

Technical Field

[0001] The invention relates to the field of rehabilitation training, and in particular to a locking structure of a suspension device. Background Art

[0002] Suspension training is a new strength training and muscle functional rehabilitation method in recent years. It is not only used in the field of sports, but also widely used in the field of rehabilitation medicine. Ceiling-mounted rehabilitation workstations usually achieve suspension training of human body parts by setting up suspension equipment at a high place through the suspension rope of the suspension equipment. In order to facilitate the position adjustment of the suspension equipment, the sliding beam of the suspension equipment is usually set to be movable relative to the guide rail, and a locking lever is set on the sliding beam. The locking lever is used to press the friction tube to generate friction, thereby achieving the fixation of the sliding beam. Among them, the friction tube is an axial fixed structure at both ends. Since the pressure of the locking lever acts on the upper surface of the friction tube, the friction tube is prone to bending and deformation due to unbalanced force, thereby affecting the fixing effect of the sliding beam and reducing the service life of the equipment. At the same time, when installing or removing the locking device, the degree of freedom of the locking device is limited due to the matching structure of the friction tube and the locking device.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The embodiment of the present invention provides a locking structure of a suspension device, referring to Figure 1 , Figure 2, including: an end beam 100, the end beam 100 is fixed under the floor, a friction tube 101 is provided on the end beam 100, and both ends of the friction tube 101 are axially installed on the end beam 100 through a bolt structure; a sliding beam 200, movably installed on the end beam 100, and the sliding beam 200 is suitable for moving along the length direction of the friction tube 101. In this embodiment, guide rails are provided on both sides of the end beam 100, the friction tube 101 is arranged parallel to the guide rails, the sliding beam 200 is provided with a ram matched with the guide rails, and the movable installation of the sliding beam 200 is realized by the cooperation between the ram and the guide rails. The sliding beam 200 is used to install the suspension component in the suspension equipment, wherein the suspension component usually includes a suspension rope and other structures, and the suspension component directly acts on the human body to perform various suspension training. The suspension component is installed under the sliding beam 200 and can move along the guide rails with the sliding beam 200, so as to adjust the position of the suspension component; the locking device 300 includes a locking lever 310 and an elastic member 320, and the finger of the locking lever 310 is hinged on the sliding beam 20 0, the left end of the locking lever 310 abuts against the upper surface of the friction tube 101, and the elastic member 320 connects the locking lever 310 and the sliding beam 200. In the natural state, the locking lever 310 moves counterclockwise under the elastic force of the elastic member 320 to press the upper surface of the friction tube 101, and the sliding beam 200 is fixed by the friction force between the locking lever 310 and the friction tube 101; the support assembly 400 is fixed to the sliding beam 200 by screws and other structures, and the support assembly 400 is suitable for abutting against the lower surface of the friction tube 101. The function of the locking device 300 is to control the locking or unlocking state of the sliding beam 200 to ensure the free movement and fixation of the sliding beam 200.

[0028] It should be noted that the function of the locking device is to control the locking state of the slide beam by contacting or separating with the friction tube. The locking device of the present invention is not limited to the locking structure described in the above embodiment. In other embodiments, reference Figure 6The locking lever 310 can also be a multi-lever structure. The locking lever 310 includes a first lever 330 and a second lever 340 rotatably mounted on the sliding beam 200. The first lever 330 is arranged on the left side, and the second lever 340 is arranged on the right side. The right end of the first lever 330 is connected to the rope body 510, and the left end of the second lever 340 is abutted against the lower surface of the right end of the first lever 330. The lower surface of the left end of the second lever 340 is connected to the sliding beam 200 through a compression spring. The left end of the first lever 330 and the right end of the second lever 340 are both abutted against the friction tube 101. In the natural state, the first lever 330 and the second lever 340 rotate counterclockwise and clockwise respectively under the elastic force of the compression spring, so that the two levers abut the friction tube 101 for fixation; when the rope body 510 is subjected to tension, the first lever 330 rotates clockwise, and its left end moves upward to separate from the friction tube 101, thereby releasing the lock on the left side of the sliding beam 200, and the left end of the second lever 340 rotates counterclockwise under the pressure of the right end of the first lever 330, thereby driving the second lever 340 to separate from the friction tube 101, thereby releasing the lock on the right side of the sliding beam 200.

[0029] A locking structure of a suspension device according to an embodiment of the present invention has at least the following beneficial effects: by arranging a support assembly on the opposite side of the locking device, and using the support assembly to abut against the friction tube, when in the locked state, the locking device presses the friction tube to generate pressure, and the support assembly provides supporting force for the friction tube to balance the force in the middle of the friction tube, preventing the friction tube from being deformed due to unilateral pressure from the locking device, thereby ensuring the strength and stability of the locking structure and improving the service life of the equipment.

[0030] In some embodiments of the present invention, reference Figure 3 The support assembly 400 includes: a support 410, which is fixed on the sliding beam 200. The support 410 of this embodiment includes a fixing part and a mounting part. The fixing part is provided with a threaded hole. The fixing part and the sliding beam 200 are fixed on the upper surface of the sliding beam 200 through a threaded connection. The mounting part is provided with a shaft body; a roller 420, which is a cylindrical structure and is mounted on the mounting part of the support 410 through a shaft body. The roller 420 and the support 410 are clearance-matched. The surface of the roller 420 is a concave arc surface that matches the friction tube 101. The roller 420 structure is used to support the friction tube 101. Its supporting surface is a concave arc surface, which is used to receive the friction tube 101 and increase the contact area between the roller 420 and the friction tube 101, thereby achieving the effect of reducing pressure, ensuring the supporting effect, and preventing damage to the friction tube 101. At the same time, since the support assembly 400 and the locking device 300 are arranged on the sliding beam 200, the support assembly 400 is movable relative to the friction tube 101. By setting a rotatable roller 420, the sliding friction between the friction tube 101 and the roller 420 can be converted into rolling friction, which can reduce the friction between the components and prevent wear.

[0031] In some embodiments of the present invention, reference Figure 1 , the elastic member 320 is a compression spring. In this embodiment, the compression spring is arranged on the right side of the locking lever 310, with the upper end connected to the lower surface of the locking lever 310 and the lower end connected to the slide beam 200. The compression spring provides an upward thrust for the locking lever 310. When there is no external force, the thrust of the compression spring drives the locking lever 310 to rotate counterclockwise, so that the left end of the locking lever 310 abuts against the friction tube 101, thereby realizing the automatic locking of the slide beam 200.

[0032] It should be understood that the role of the elastic member is to provide elastic force to drive the locking lever to rotate. The elastic member of the present invention is not limited to the compression spring structure described in the above embodiment. In other embodiments, the elastic member can also be a tensile elastic member such as a tension spring. The tension spring is arranged on the left side of the locking lever, connecting the slide beam and the lower surface of the locking lever. The tension spring provides a downward pulling force for the locking lever, driving the locking lever to rotate counterclockwise to achieve automatic locking of the slide beam. The elastic member can also be a torsion spring arranged at the fulcrum of the locking lever, which drives the locking lever to rotate to achieve locking.

[0033] In some embodiments of the present invention, reference Figure 1 A wear-resistant rubber layer is provided at one end of the locking lever, and the wear-resistant rubber layer 311 is provided on the abutting surface between the locking lever 310 and the friction tube 101. The wear-resistant rubber layer 311 structure can prevent the wear of the metal material between the locking lever 310 and the friction tube 101, and at the same time can increase the friction between the locking lever 310 and the friction tube 101, thereby improving the locking effect.

[0034] In some embodiments of the present invention, reference Figure 1 , Figure 4 The locking device 300 further includes a rope assembly 500 connected to the right end of the locking lever 310. The rope assembly 500 is adapted to control the rotation of the locking lever 310. By using an external force to pull the rope assembly 500 downward, the locking lever 310 is driven to overcome the elastic force of the elastic member 320, so that the locking lever 310 moves clockwise and separates from the friction tube 101, thereby unlocking the locking lever 310.

[0035] In some embodiments of the present invention, reference Figure 1 , Figure 5The rope assembly 500 includes a rope body 510 and a limiting device 520. The rope body 510 is connected to the other end of the locking lever 310. The limiting device 520 is arranged on the rope body 510. The locking portion 210 is fixed to the sliding beam 200 by screw connection. The limiting device 520 is suitable for cooperating with the locking portion 210 to fix the locking device. In this embodiment, the locking lever 310 is hollow inside. A fixing pin is arranged at the right end of the locking lever 310. One end of the rope body 510 is accommodated inside the locking lever 310. The fixing pin passes through the locking lever 310 and the rope body 510 at the same time, so as to fix the locking lever 310 and the rope body 510. The locking lever 310 is separated from the friction tube 101 by pulling down the rope 510, thereby unlocking the slide beam 200. When the rope 510 is in the pulled-down state, the limiting device 520 is used to abut against the lock portion 210 to fix the rope 510 and the locking lever 310, so that the locking lever 310 and the friction tube 101 remain separated, thereby keeping the slide beam 200 in the unlocked state. The rope control structure of the present invention can maintain the unlocked state of the locking lever 310 without the aid of external force, and can freely switch the locking and unlocking states of the locking lever 310, and has the advantages of simple and convenient operation and easy structure implementation.

[0036] In some embodiments of the present invention, reference Figure 4 The limiting device 520 includes a locking ring 521 and a locking screw 522. The locking ring 521 is sleeved on the rope body 510, and the locking screw 522 can detachably connect the rope body 510 and the locking ring 521. In this embodiment, three threaded holes are arranged on both sides of the locking ring 521, and a through hole is arranged in the middle of the locking ring 521 along the vertical direction. The rope body 510 is installed in the through hole of the locking ring 521 and fixed by the cooperation of the screw and the threaded hole. By providing a detachable limiting device 520, the position of the limiting device 520 relative to the rope body 510 can be freely adjusted, and the distance between the limiting device 520 and the locking lever 310 can be changed. Through the cooperation between the limiting device 520 and the locking part 210, the separation length of the locking lever 310 and the friction tube 101 can be changed.

[0037] In some embodiments of the present invention, reference Figure 5 The lock part 210 is provided with a rope guide groove 211 along the vertical direction that matches the rope body 510, and the rope guide groove 211 is suitable for accommodating the rope body 510. In the matching structure of the lock part 210 and the limiting device 520 of this embodiment, in the natural state, the rope body 510 is arranged outside the lock part 210, and the limiting device 520 and the lock part 210 are in a separated state; when the rope body 510 is subjected to tension, the rope body 510 is inserted into the rope guide groove 211, and the upper end of the lock is abutted against the lower end of the lock part 210, thereby fixing the rope body 510. It has the advantages of simple fixing structure and convenient operation.

[0038] In some embodiments of the present invention, reference Figure 6The sliding beam 200 includes a long slot 220 and a bracket 230. The bracket 230 is detachably mounted on the sliding beam 200. The locking device 300 is arranged on the bracket 230. The long slot 220 is arranged in the left-right direction. The bracket 230 extends downward through the long slot 220 and is provided with a hanging ear 231. The hanging ear 231 is suitable for moving in the long slot 220. In this embodiment, the bracket 230 includes a bottom plate and two mutually parallel side plates. The side plates are vertically arranged on the upper surface of the bottom plate. The side plates are integrally formed with the bottom plate. One end of the bottom plate of the bracket 230 extends downward through the sliding slot and is provided with a hanging ear 231. The hanging ear 231 is used to install the structure of other suspension components such as a suspension rope. The locking lever 310 is hinged between the two side plates through an axle. By setting a detachable bracket 230 structure in the slide beam 200 to install the locking device 300, when disassembling the locking device 300 and the support assembly 400, the lug 231 at the lower end of the bracket 230 is moved along the slide groove to separate the locking device 300 from the friction tube 101, so that the bracket 230 can be removed, which facilitates the disassembly and maintenance of the locking device 300. At the same time, when installing the bracket 230 on the slide beam 200, the cooperation between the slide groove and the lug 231 is used to achieve the initial positioning of the bracket 230, so as to ensure the installation accuracy of the locking device 300.

[0039] In some embodiments of the present invention, reference Figure 6 , further comprising a connecting member 201, the bracket 230 and the sliding beam 200 are provided with mutually matching mounting holes 202, the connecting member 201 is arranged in the mounting hole 202, and the bracket 230 and the sliding beam 200 are detachably connected through the connecting member 201. In this embodiment, the connecting member 201 is a screw member, and the mounting hole 202 is a threaded hole, and the detachable connection between the bracket 230 and the sliding beam 200 is achieved by threaded connection between the screw member and the threaded hole.
