Description

Technical Field

[0001] This invention relates to the field of fitness equipment technology, and in particular to a clamp-type rope clamp. Background Technology

[0002] Existing Pilates beds often use training cables. One end of these cables needs to be fixed to the movable bed board of the Pilates bed, while the other end is for the user. Current cable-fixing methods primarily involve two symmetrically distributed clamping blocks. These clamping blocks form a funnel-shaped channel for the cable to pass through. The clamping blocks have toothed protrusions on the sidewalls of the channel to press the cable surface. The two clamping blocks are mounted via torsion springs, maintaining a tight pressure towards the center of the channel and ensuring close contact with the cable. When the cable moves towards the narrower end of the channel, the clamping blocks open due to elasticity, allowing the cable to pass smoothly. When the cable moves towards the wider end of the channel, the two clamping blocks press the cable firmly. This fixing structure suffers from poor structural stability and susceptibility to damage under high-intensity training conditions. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a clamp-type rope clamp that can maintain the fixation of the rope end during long-term, high-intensity training and has a flexible rope adjustment structure.

[0004] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: A clamp-type rope clamp, comprising a rope clamp body, characterized in that: The rope clamp body has a flat structure, and the middle part of the rope clamp body has an assembly space for installing other components. And a first rope clamping block and a second rope clamping block installed in the assembly space of the rope clamping device body, the first rope clamping block and the second rope clamping block forming a rope clamping channel for the pull rope to pass through. And a pressing spring, which is installed on any side surface of the rope clamp body and is movably arranged along the direction of the rope distribution; the pressing spring is connected to the rope clamp body through an elastic element and the pressing spring is fixed at the initial position at one end of its moving area by the elastic element. The pressing spring is connected to the first and / or second rope clamping blocks. The pressing spring controls the first and / or second rope clamping blocks to swing synchronously, which is used to tighten or loosen the rope.

[0005] The first rope clamping block is fixedly mounted on the rope clamping device body, the outer end of the second rope clamping block is rotatably mounted on the rope clamping device body, and the inner end of the second rope clamping block is freely swinging; or The outer ends of the first and second rope clamping blocks are rotatably mounted on the rope clamping device body, while the inner ends of the first and second rope clamping blocks are freely swinging.

[0006] The rope clamp body is provided with an arc-shaped limiting channel for restricting the free swing of the first rope clamp block and / or the second rope clamp block. The pressing spring is provided with a first linear limiting channel for controlling the synchronized movement of the free swing ends of the first rope clamping block and / or the second rope clamping block. The first rope clamping block and / or the second rope clamping block are provided with a first limiting member connected thereto, and the first limiting member is located in the arc-shaped limiting channel and the first straight limiting channel, respectively.

[0007] The pressing spring is provided with a second linear limiting channel distributed along the direction of the pull rope, and a second limiting member connected to the rope clamp body is provided in the second linear limiting channel.

[0008] The pressing spring is arranged parallel to the distribution direction of the pull rope and is located directly above or directly below the pull rope.

[0009] The end of the pressing spring is provided with a pressing plate that is connected and fixed thereto.

[0010] The pressing plate has a through hole in the middle, and the pull rope passes through the through hole.

[0011] The rope clamp body is also equipped with a guide wheel that is rotatably connected to it. After the rope enters the rope clamp body, it passes through the rope clamping channel and the guide wheel and leaves the rope clamp body.

[0012] The rope clamp body includes two sets of panels located at the top and bottom, with the assembly space formed between the two sets of panels.

[0013] One set of the panels has a side guard plate on its edge, and the side guard plate is located on the outside of the pull cord.

[0014] The beneficial effects of this invention are: the structural design is reasonable, and this technical solution replaces the traditional method of fixing by clamping rope blocks. By adopting a highly integrated and structurally more stable clamp-type rope clamp, it not only effectively restricts and protects the movement path of the rope, but also makes the internal rope clamping block installation structure for fixing the rope more stable. When it is necessary to adjust the position of the rope, the second rope clamp can be moved synchronously by pressing the spring piece, thereby releasing the rope for length adjustment. Under long-term, high-intensity training conditions, the fixed effect of the rope end is always maintained, and it has a flexible rope adjustment structure. Attached Figure Description

Detailed Implementation

[0022] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0023] according to Figures 1 to 6 As shown: This embodiment provides a clamp-type rope clamp, including a rope clamp body. The rope clamp body consists of two sets of panels, two sets of clamping blocks, a set of guide wheels 700, a set of pressing springs 300, and a pull rope 400. The pull rope 400 is a conventional accessory of Pilates bed. After assembly, the rope clamp body can be installed on the bottom surface of the movable bed board of the Pilates bed. The top surface of the rope clamp body faces the bottom surface of the movable bed board and is fixed in place. The pull rope 400 enters the rope clamp body from one side edge, locks after a 180-degree turn, and leaves the rope clamp body from the middle. The specific assembly structure of the above components is described below.

[0024] The rope clamp body has a flat structure, including a first panel 100 on the bottom surface and a second panel 200 on the top surface. The first panel 100 and the second panel 200 form an assembly space for installing other components. The assembly space is mainly used to install the rope clamping block and the guide wheel 700. The pull rope 400 is located in the assembly space and is set through the rope clamping block and the guide wheel 700. The pressing spring 300 is installed on the outer side of the bottom surface of the rope clamp body, so that it has sufficient installation space and meets the movement needs of the pressing spring 300. For details, please refer to the following: Figure 3 , Figure 6 The upper side of the first panel 100 is provided with an integral side guard plate 101. The side guard plate 101 is bent at 90 degrees and located on the outside of the pull rope 400, so that it can protect the outside of the pull rope 400 and make it leave the rope clamp body according to a preset path. The left edge of the first panel 100 is also provided with a circular protruding guide wheel guard plate 102. The guide wheel guard plate 102 is located directly below the guide wheel 700 and is used to protect the guide wheel 700 and the pull rope 400.

[0025] The two sets of rope clamping blocks include a first rope clamping block 801 and a second rope clamping block 802. The first rope clamping block 801 and the second rope clamping block 802 are installed in the middle of the assembly space, and a rope clamping channel for the pull rope 400 to pass through is formed between the first rope clamping block 801 and the second rope clamping block 802; wherein: For details, please refer to the following: Figure 3 , Figure 6 The first rope clamping block 801 is fixedly installed on the rope clamping device body and is located near the upper part. The first rope clamping block 801 has two mounting holes and is fixed to the first panel 100 and the second panel 200 respectively by two sets of screws, so that it cannot be moved. The surface of the first rope clamping block 801 facing the rope clamping channel is provided with tooth-shaped protrusions, which can lock the movement of the pull rope 400 in one direction. For details, please refer to the following: Figure 6 The outer end of the second rope clamping block 802 is rotatably mounted on the first panel 100 and the second panel 200 via a pin and is located near the lower part. The inner end of the second rope clamping block 802 is freely swinging. At the same time, a toothed protrusion is provided on the side surface of the second rope clamping block 802 facing the rope clamping channel. The toothed protrusion can lock the movement of the pull rope 400 in one direction. With the first rope clamping block 801 and the second rope clamping block 802 working together to clamp the pull rope 400, when the pull rope 400 moves into the body of the rope clamper, it can move through the rope clamping channel between the toothed protrusions. When the pull rope 400 moves out of the body of the rope clamper, it will be bitten by the toothed protrusions of the first rope clamping block 801 and the second rope clamping block 802 and cannot move, thus locking the pull rope 400 in the rope clamping channel.

[0026] For details, please refer to the following: Figure 3 , Figure 6 Based on the installation positions of the two sets of rope clamping blocks mentioned above, the guide wheel 700 is installed on the left side of the first rope clamping block 801. The guide wheel 700 is rotatably installed on the first panel 100 and the second panel 200 respectively. After the pull rope 400 enters the rope clamping device body, it first passes through the guide wheel 700 for direction adjustment, and then enters the rope clamping channel and leaves the rope clamping device body.

[0027] The pressing spring 300 is installed at the lower part of the first panel 100. The pressing spring 300 is movably arranged along the distribution direction of the pull rope 400 and is located directly below the rope clamping channel. Two sets of second linear limiting channels 304 are provided on the pressing spring 300 along the distribution direction of the pull rope 400. The second linear limiting channels 304 are elongated holes that meet the requirements of their movable length, and a second limiting member 502 connected to the first panel 100 is provided within the second linear limiting channel 304. When the pressing spring 300 moves to the left or right, it is controlled by the second limiting member 502 and the second linear limiting channel 304. The positioning of the pressing spring 300 is limited; at the same time, the left end of the pressing spring 300 and the right side of the first panel 100 are connected by an elastic element, which is a spring. The pressing spring 300 is provided with a second mounting part 303 for connecting with the spring, and the first panel 100 is provided with a first mounting part 103 for connecting with the spring. Both the first mounting part 103 and the second mounting part 303 are obtained by bending at 90 degrees. The pressing spring 300 can be pulled to the right by the elastic element, so that the second limiting member 502 is located at the leftmost end of the second linear limiting channel 304. This position is the initial position of the pressing spring 300. Based on the installation structure and initial position of the pressing spring 300 described above, the structural design of the pressing spring 300 also indirectly controls the clamping effect on the pull rope 400 in order to simultaneously control the swinging effect of the second rope clamping block 802. Specifically: The first panel 100 is provided with an arc-shaped limiting channel 600 for restricting the free swing of the second rope clamping block 802. The arc-shaped limiting channel 600 is centered on the fixed point of the second rope clamping block 802 and is the same as the swing path of the second rope clamping block 802. The specific position of the arc-shaped limiting channel 600 should also take into account the cooperation effect of the first rope clamping block 801 and the second rope clamping block 802, and match the need for the pull rope 400 to pass through the rope clamping channel, including the minimum gap between the first rope clamping block 801 and the second rope clamping block 802, the diameter of the pull rope 400, and other parameters. The pressing spring 300 is provided with a first linear limiting channel 301 for controlling the free swing end of the second rope clamping block 802 to move synchronously. The first linear limiting channel 301 is located on a side ear on the side of the pressing spring 300 and is set perpendicular to the distribution direction of the pressing spring 300. For details, please refer to the following: Figure 3 , Figure 6 Based on the above structure, the second rope clamping block 802 is provided with a first limiting member 501 connected thereto. The first limiting member 501 is located in the arc-shaped limiting channel 600 and the first straight limiting channel 301 respectively. The specific working principle of the pressing spring 300 controlling the second rope clamping block 802 to swing synchronously is as follows: When the spring 300 is pressed in the initial position, the first limiting member 501 is located at the right end of the arc-shaped limiting channel 600 and the upper end of the first straight limiting channel 301. At this time, the second rope clamping block 802 is set close to the first rope clamping block 801, and the first rope clamping block 801 and the second rope clamping block 802 press the pull rope 400 together. When the pressing spring 300 slides to the left, the elastic element extends, and the first limiting member 501 moves from the right end of the arc-shaped limiting channel 600 to the left end. The first limiting member 501 slides from the upper end of the first straight limiting channel 301 to the lower end until it reaches the left end of the arc-shaped limiting channel 600 and the lower end of the first straight limiting channel 301. At this time, the second rope clamping block 802 is furthest from the first rope clamping block 801, and the rope clamping channel is in an open state relative to the pull rope 400. At this time, the pull rope 400 can move arbitrarily to adjust its length. When the pressing spring 300 is released, the elastic element shortens, the pressing spring 300 returns to its initial position, and the first limiting element 501 and the second rope clamping block 802 also return to their initial positions, thereby pressing the pull rope 400. In the above description of the specific working principle, in order to facilitate the sliding effect of the pressing spring 300, a pressing plate 302 is provided at the right end of the pressing spring 300 and is fixed thereto. The pressing plate 302 is bent upward and has a through hole in the middle, through which the pull rope 400 passes. In this way, the position of the pull rope 400 can be controlled by the through hole, and the pressing spring 300 can also be slid by the pressing plate 302, which facilitates operation.

[0028] In the above embodiments, for the assembly structure of the first rope clamping block 801 and the second rope clamping block 802, the first rope clamping block 801 can also be installed according to the rotational assembly structure of the second rope clamping block 802. At the same time, the corresponding component structure such as the pressing spring 300 can be adjusted so that the pressing spring 300 cooperates with the two sets of rope clamping blocks to perform actions simultaneously, and the two sets of rope clamping blocks can synchronously complete the action of pressing or releasing the pull rope 400.

[0029] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by essentially the same means shall fall within the protection scope of the present invention.
