Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, and in particular to a leg-shaping clip. Background Technology

[0002] Chinese patent specification CN219848027U discloses a new type of leg clamp that addresses the problem of tilting caused by asymmetrical force application in existing leg clamps. This new clamp uses a transmission component and a pull rod to connect the two clamping parts and the resistance controller, thus solving the problem of tilting caused by asymmetrical force application in existing leg clamps. However, it has shortcomings in its structural design:

[0003] This leg clamp uses a pull rod to compress a spring and generate resistance. This design requires the pull rod to be combined with multiple components such as a blocking section and a top block to achieve connection and motion transmission, making the overall structure quite complex. During long-term use, the connection points between the pull rod and other components are prone to wear and loosening, which may even lead to component detachment, posing a safety hazard. Furthermore, the complex structure increases the difficulty of product maintenance and installation, and also increases the failure rate. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a foot clip that uses a design where the transmission component and the resistance spring directly abut against each other. This design not only reduces the risk of failure and improves stability and reliability, but also has the advantages of simple structure, low cost, and easy maintenance and installation.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A leg clamp includes a main body and two leg clamps rotatably mounted on the main body and capable of being retracted and extended. The main body includes a main shell, a transmission component disposed in the upper part of the main shell, a resistance spring disposed in the lower part of the main shell and engaging with the transmission component, and a transmission structure for transmitting the transmission component to the two leg clamps. The transmission structure includes two transmission columns disposed on opposite sides of the transmission component and axially offset, and a transmission groove disposed on each leg clamp. The two leg clamps are respectively disposed on both sides of the transmission component, and the two transmission columns extend into the transmission grooves on the corresponding leg clamps and form a transmission engagement with them. When the two leg clamps are retracted, the transmission groove drives the transmission columns to displace the transmission component downward, thereby compressing the resistance spring and generating resistance to the retraction of the two leg clamps. Conversely, when the two leg clamps are extended, the transmission groove drives the transmission columns to return the transmission component to its original position upward, and causes the resistance spring to return to its original position upward.

[0007] Furthermore, the transmission structure also includes a transmission turntable fixedly connected to each leg clamp, and a transmission groove on each leg clamp is provided on the corresponding transmission turntable. The transmission groove is a horizontal sliding groove extending in the left-right direction.

[0008] Furthermore, the two leg clamps are rotatably mounted on the main body shell via a transmission turntable on each leg clamp.

[0009] Furthermore, the transmission turntable is provided with a pivot hole, and support seats are provided on both the front and rear sides of the upper end of the main body shell. The transmission component is located between the two support seats. The main body shell is provided with a pivot, which passes through the two support seats and the transmission component. The two leg clamps are pivotally connected to the front and rear ends of the pivot respectively through the pivot holes on the corresponding transmission turntable. The transmission component is provided with a first clearance groove for the pivot to pass through and is arranged in the vertical direction. When the transmission component moves downward or upward, it avoids the pivot through the first clearance groove.

[0010] Furthermore, the pivot includes a first pivot and a second pivot. One end of the first pivot is provided with a first nut, and the other end of the first pivot is provided with an external thread. One end of the second pivot is provided with a second nut, and the other end of the second pivot is provided with a first threaded hole that can be threadedly connected to the external thread on the first pivot.

[0011] Furthermore, both the first nut and the second nut have a screw-in notch on their end faces for screwing in with a screwdriver. The screw-in notch is either a slotted or cross-shaped structure.

[0012] Furthermore, both of the support seats have grooves on their outer sides for accommodating the transmission turntables. The second pivot passes through the pivot hole on one of the transmission turntables and the second nut on the second pivot abuts against the outer side of the transmission turntable. The first pivot passes through the pivot hole on the other transmission turntable and the first nut on the first pivot abuts against the outer side of the transmission turntable. The external thread on the first pivot is threadedly connected to the first threaded hole on the second pivot. A gap is reserved between the inner side of each of the two transmission turntables and the bottom wall of the groove on the corresponding support seat.

[0013] Furthermore, each of the two transmission turntables is provided with at least two second threaded holes evenly distributed on the outside of the pivot hole. The two leg clamps are provided with through holes corresponding to the positions of the second threaded holes on the transmission turntables. The two leg clamps are also provided with screws corresponding to the number of second threaded holes and through holes. The screws pass through the through holes and extend into the second threaded holes to be threadedly connected to them, so that the transmission turntables are fixedly connected to the corresponding leg clamps.

[0014] Furthermore, each of the two support seats is provided with a second clearance groove for the corresponding transmission column to move up and down, and the two transmission columns pass through the corresponding second clearance groove.

[0015] Furthermore, a stop washer is provided in the lower part of the main body shell. The upper and lower ends of the resistance spring abut against the transmission component and the stop washer, respectively. A threaded through hole is provided on the bottom wall of the main body shell. An adjusting screw is screwed into the threaded through hole. The upper end of the adjusting screw abuts against the lower surface of the stop washer. The lower end of the adjusting screw extends out of the main body shell and is fixedly connected to an adjusting knob.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This utility model adopts a design in which the transmission component and the resistance spring directly abut against each other, eliminating parts such as the pull rod. This not only makes the overall structure more compact and sophisticated, but also significantly reduces costs. At the same time, the reduced number of parts lowers the risk of failure due to component wear and loose connections, significantly improving the stability and reliability of the product.

[0025] The present invention will be further described in detail below with reference to the embodiments shown in the accompanying drawings.

[0026] like Figures 1 to 7As shown, a leg clamp includes a main body 1 and two leg clamping parts 2 rotatably mounted on the main body 1 and capable of being retracted and unfolded. The main body 1 includes a main body shell 11, a transmission component 12 disposed in the upper part of the main body shell 11, a resistance spring 13 disposed in the lower part of the main body shell 11 and engaging with the transmission component 12, and a transmission structure 3 for transmitting a transmission connection between the transmission component 12 and the two leg clamping parts 2. The transmission structure 3 includes two transmission columns 31 disposed on opposite sides of the transmission component 12 and axially offset, and a transmission spring 31 disposed on each leg clamping part 2. The moving groove 32 and the two leg clamps 2 are respectively set on both sides of the transmission member 12. The two transmission columns 31 extend into the corresponding leg clamps 2 and form a transmission engagement with them. When the two leg clamps 2 are closed, the transmission groove 32 drives the transmission column 31 to move the transmission member 12 downward and squeeze the resistance spring 13, thereby generating resistance to the closing of the two leg clamps 2. Conversely, when the two leg clamps 2 are unfolded, the transmission groove 32 drives the transmission column 31 to return the transmission member 12 to the upward position and cause the resistance spring 13 to reset upward.

[0027] As described above, the transmission structure 3 also includes a transmission turntable 33 fixedly connected to each leg clamp 2. The transmission groove 32 on each leg clamp 2 is set on the corresponding transmission turntable 33. The transmission groove 32 is a horizontal sliding groove that extends in the left and right direction. When the two leg clamps 2 are closed or unfolded, the two transmission columns 31 slide in the corresponding horizontal sliding grooves, thereby driving the transmission component 12 to move downward or upward.

[0028] As described above, the two leg clamps 2 are rotatably mounted on the main body shell 11 via the transmission turntable 33 on them.

[0029] As described above, the transmission turntable 33 is provided with a pivot hole 331, and support seats 14 are provided on both the front and rear sides of the upper end of the main body shell 11.

The two leg clamps 2 are pivotally connected to the front and rear ends of the pivot 15 through the corresponding pivot holes 331 on the transmission turntable 33. The transmission component 12 is provided with a first clearance groove 121 for the pivot 15 to pass through and is arranged in the vertical direction. When the transmission component 12 moves downward or upward, it avoids the pivot 15 through the first clearance groove 121.

One end of the first pivot 151 is provided with a first nut 153 and the other end of the first pivot 151 is provided with an external thread. One end of the second pivot 152 is provided with a second nut 154 and the other end of the second pivot 152 is provided with a first threaded hole 155 that can be threadedly connected to the external thread on the first pivot 151.

[0031] As described above, both the first nut 153 and the second nut 154 have screw-in notches on their end faces for screwing in with a screwdriver. The screw-in notches are either in a slotted or cross shape.

[0032] As described above, both support bases 14 are provided with grooves 141 on their outer sides for accommodating transmission turntables 33. The second pivot 152 passes through the pivot hole 331 on either transmission turntable 33 and the second nut 154 on the second pivot 152 abuts against the outer side of the transmission turntable 33. The first pivot 151 passes through the pivot hole 331 on the other transmission turntable 33 and the first nut 153 on the first pivot 151 abuts against the outer side of the transmission turntable 33. The external thread on the first pivot 151 is threadedly connected to the first threaded hole 155 on the second pivot 152. The inner sides of the two transmission turntables 33 are respectively reserved with the bottom wall of the groove 141 on the corresponding support base 14.

[0033] As described above, each of the two transmission turntables 33 is provided with at least two second threaded holes 332 evenly distributed on the outside of the pivot hole 331. The two leg clamps 2 are provided with through holes 21 corresponding to the positions of the second threaded holes 332 on the transmission turntables 33. They also include screws corresponding to the number of second threaded holes 332 and through holes 21. The screws pass through the through holes 21 and extend into the second threaded holes 332 to be threadedly connected to them, so that the transmission turntables 33 are fixedly connected to the corresponding leg clamps 2.

[0034] As described above, the two support bases 14 are respectively provided with second clearance grooves 142 for the corresponding transmission column 31 to move up and down, and the two transmission columns 31 respectively pass through the corresponding second clearance grooves 142.

[0035] As described above, a stop washer 16 is also provided in the lower part of the main body shell 11. The upper and lower ends of the resistance spring 13 abut against the transmission component 12 and the stop washer 16, respectively. A threaded through hole 17 is provided on the bottom wall of the main body shell 11. An adjusting screw 18 is screwed into the threaded through hole 17. The upper end of the adjusting screw 18 abuts against the lower surface of the stop washer 16, and the lower end of the adjusting screw 18 extends out of the main body shell 11 and is fixedly connected to an adjusting knob 19. In use, the adjusting knob 19 is held and turned to adjust the up and down position of the stop washer 16 through the threaded through hole 17, thereby adjusting the resistance of the resistance spring 13.

[0036] The above description is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the scope of the present utility model patent application and the description of the utility model shall still fall within the scope of the present utility model patent.
