[0025] In order to make the purpose, features, and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the embodiments of the present application.

[0026] See also Figures 1 to 4 According to an embodiment of the present application, a fitness puller is provided, comprising: a housing 1, a tension rope 2, a rope wheel 3 and a damping return mechanism 4; the tension rope 2 is passed through the housing 1, the first end of the tension rope 2 is located outside the housing 1, the second end of the tension rope 2 is located inside the housing 1, and the second end of the tension rope 2 is wound around the rope wheel 3; the rope wheel 3 is rotatably connected to the inside of the housing 1, and is connected to the damping return mechanism 4 through a linkage 5; the damping return mechanism 4 is arranged inside the housing 1, and comprises a webbing wheel 41, a webbing 42 and an elastic member 43, the webbing wheel 4 The first end of the webbing 42 is wound around the webbing wheel 41, and the second end of the webbing 42 is connected to the elastic member 43, which is arranged inside the housing 1. When the tension rope 2 is pulled out toward the outside of the housing 1, the rope wheel 3 releases the tension rope 2, and the webbing wheel 41 is linked to take up the webbing 42. The elastic member 43 is elastically deformed, so that the webbing 42 has a movement tendency to leave the webbing wheel 41. When the webbing 42 leaves the webbing wheel 41, the rope wheel 3 takes up the tension rope 2.

[0027] The embodiment of the present application provides a fitness puller, which winds the tension rope 2 around the rope wheel 3. When the user applies force to the tension rope 2 and pulls the tension rope 2 out of the housing 1, the rope wheel 3 rotates and transmits the force to the webbing wheel 41 through the linkage 5. The webbing wheel 41 retracts the webbing 42, thereby deforming the elastic member 43 to form resistance, hindering the user's withdrawal action, and achieving the damping effect of the puller; when the user completes a pulling action, the user stops applying force to the tension rope 2. Since the elastic member 43 is in a deformed state, the webbing 42 has a movement tendency to leave the webbing wheel 41, and the elastic member 43 returns to the initial state, driving the webbing 42 to be pulled out from the webbing wheel 41. The webbing wheel 41 rotates, and the rope wheel 3 rotates through the linkage 5, and the rope wheel 3 retracts the tension rope 2. The fitness puller meets the user's demand for tension fitness through a purely mechanical structure, is low-cost and not easy to damage, and can meet the needs of most users.

[0028] In the embodiment of the present application, the housing 1 may be a metal housing 1, which is used to protect the components in the housing 1. A positioning frame 11 is fixed inside the housing 1 for rotationally connecting the rope pulley 3 and the webbing pulley 41. Further, a bearing seat 12 may be installed on the positioning frame 11, and the rope pulley 3 and the webbing pulley 41 may be connected to the bearing seat 12 through a bearing, so that the rope pulley 3 and the webbing pulley 41 can rotate stably and smoothly relative to the housing 1.

[0029] The rope wheel 3 and the webbing wheel 41 are connected by a linkage 5 so that they can rotate synchronously. According to the specific type of the linkage 5, the rope wheel 3 and the webbing wheel 41 can rotate in the same direction or in opposite directions. It is only necessary to satisfy that when the rope wheel 3 is in the rope-retracting action, the webbing wheel 41 is in the belt-releasing action, and when the rope wheel 3 is in the rope-releasing action, the webbing wheel 41 is in the belt-retracting action.

[0030] In this way, when the rope wheel 3 releases the rope, the webbing wheel 41 reels the webbing, and the webbing 42 pulls the elastic member 43, causing the elastic member 43 to deform. The elastic potential energy generated by the deformation of the elastic member 43 forms an obstacle to achieve damping of the rope wheel 3 and meet the user's limit on the tension weight of the tensioner. The elastic member 43 can be fixed in the housing 1 at any position that will be pulled and deformed by the webbing 42 when the webbing wheel 41 reels the webbing.

[0031] It should be added that, in the embodiment of the present application, a tension module is mainly formed by a tension rope 2, a rope wheel 3, and a damping return mechanism 4. According to actual needs, at least one or more tension modules can be set in the shell 1, and the tension modules do not affect each other.

[0032] In one embodiment, the linkage member 5 includes a first linkage gear 51 and a second linkage gear 52 . The first linkage gear 51 rotates synchronously with the rope wheel 3 , and the second linkage gear 52 rotates synchronously with the webbing wheel 41 . The first linkage gear 51 meshes with the second linkage gear 52 .

[0033] When the rope wheel 3 and the webbing wheel 41 are linked by gears, the linkage member 5 may include a first linkage gear 51 and a second linkage gear 52. The first linkage gear 51 is coaxially fixed to the rope wheel 3 so that the first linkage gear 51 can rotate synchronously with the rope wheel 3. The second linkage gear 52 is coaxially fixed to the webbing wheel 41 so that the second linkage gear 52 can rotate synchronously with the webbing wheel 41. Through the meshing of the first linkage gear 51 and the second linkage gear 52, the rope wheel 3 can rotate synchronously in the opposite direction with the webbing wheel 41.

[0034] It should be added that the linkage member 5 only needs to satisfy the linkage rotation of the rope wheel 3 and the webbing wheel 41. The linkage member 5 of the present application can also be a single-gear linkage member 5, a multi-gear linkage member 5, a gear rack linkage member 5 or other non-gear linkage forms.

[0035] In another specific implementation scenario, the first linkage gear 51 may be a part of the structure of the rope wheel, and the second linkage gear 52 may be a part of the structure of the webbing wheel 41.

[0036] In one possible embodiment, the diameter of the first linkage gear 51 is smaller than the diameter of the second linkage gear 52; and / or the diameter of the rope twisting portion of the rope twisting wheel 3 is larger than the diameter of the tape taking portion of the webbing wheel 41; and / or the diameter of the first linkage gear 51 is smaller than the diameter of the rope twisting wheel 3; and / or the diameter of the second linkage gear 52 is larger than the diameter of the tape taking portion of the webbing wheel 41.

[0037] The rope portion is used to refer to the area in the rope wheel 3 for winding the tension rope 2, and the webbing 42 portion is used to refer to the area in the webbing wheel 41 for winding the webbing 42. By limiting the diameters of the first linkage gear 51, the second linkage gear 52, the rope wheel 3 and the webbing wheel 41, the rotation angular velocity of the webbing wheel 41 can be slower than the rotation angular velocity of the rope wheel 3, and the length of the webbing 42 wound by one rotation of the webbing wheel 41 can be shorter than the length of the tension rope 2 wound by one rotation of the rope wheel 3, thereby making the total length of the webbing 42 in the shell 1 much shorter than the length of the tension rope 2, reducing the space required for the damping return mechanism 4 in the shell 1, thereby reducing the size of the shell 1 as a whole, and reducing the overall size of the fitness puller to meet family needs.

[0038] In a specific implementation scenario, the diameter of the rope portion is larger than the outer diameter of the first linkage gear 51, the outer diameter of the first linkage gear 51 is smaller than the outer diameter of the second linkage gear 52, the outer diameter of the second linkage gear 52 is larger than the diameter of the belt taking-up portion, and the diameter of the rope portion is larger than the diameter of the belt taking-up portion.

[0039] In one embodiment, a sliding seat 61 is slidingly connected to the shell 1, and the shell 1 forms a sliding channel 18 for connecting the sliding seat 61, and the channel direction of the sliding channel 18 is consistent with the rotation direction of the webbing wheel 41 and the rope wheel 3; the elastic member 43 is fixed on the sliding seat 61, and a fastener 62 is also provided on the shell 1, and the fastener 62 is used to fix the sliding seat 61 at a specified position of the shell 1.

[0040] Specifically, the shell 1 is provided with a sliding channel 18 in the same direction of rotation as the webbing wheel 41 and the rope wheel 3. The sliding seat 61 is connected in the sliding channel 18. The sliding seat 61 can change the distance between the webbing wheel 41 during the sliding process, so that the distance between the elastic member 43 and the webbing wheel 41 can be changed through the sliding of the sliding seat 61, thereby changing the damping force of the damping return mechanism 4.

[0041] Specifically, an indicator mark for indicating the position of the sliding seat 61 can be set on the shell 1. When the indicator mark shows that the sliding seat 61 is in the first position, at this time, the distance between the sliding seat 61 and the webbing wheel 41 is the length of the elastic member 43 in the normal state plus the length of the webbing 42. In this way, when the sliding seat 61 is in the first position, the elastic member 43 is in a normal state, and the webbing 42 is in a just straightened state.

[0042] With the first position as a reference, an area where the sliding seat 61 slides in a direction away from the webbing wheel 41 is referred to as a first area, and an area where the sliding seat 61 slides in a direction close to the webbing wheel 41 is referred to as a second area.

[0043] Based on the first position, if the sliding seat 61 slides in the direction away from the webbing wheel 41, in the first area, since the length of the webbing 42 remains unchanged, the farther the sliding seat 61 is away from the webbing wheel 41, the higher the deformation degree of the elastic member 43 is, and the greater the elastic potential energy generated thereby. In this state, when the user uses the tension rope 2, the damping force that can be provided is also greater.

[0044] Based on the first position, if the sliding seat 61 slides toward the direction close to the webbing wheel 41, in the second area, since the length of the webbing 42 remains unchanged, the closer the sliding seat 61 is to the webbing wheel 41, the elastic member 43 is still in a normal state, and the webbing 42 is in a relaxed state. In this state, when the user initially pulls the tension rope 2 outward, the webbing 42 needs to return from the relaxed state to the tightened state, that is, when the user pulls the initial part of the tension rope 2, the damping recovery mechanism 4 does not provide a damping force. The user can adjust the length of the tension rope 2 with damping force in this way, so that the tensioner can better meet the actual needs of the user.

[0045] In actual operation, the sliding seat 61 can be arranged on the side of the sliding channel 18 facing the outside of the housing 1. In this way, during the sliding process of the sliding seat 61, the user can intuitively observe the raised height or recessed height of the sliding seat 61 relative to the housing 1. Correspondingly, the indicator mark can be marked by the raised height and recessed height of the sliding seat 61 relative to the housing 1. Specifically, the indicator mark can convert the raised height and recessed height of the sliding seat 61 relative to the housing 1 into the corresponding damping force and / or the length of the tension rope 2 and print it on the sliding seat 61 and / or the housing 1.

[0046] The fastener 62 may be a fastening bolt, which is passed through the housing 1 and threadedly connected to the sliding seat 61. The sliding direction of the sliding seat 61 is limited by the sliding channel 18. The fastening bolt is used to enable the sliding seat 61 to slide relative to the housing 1 in the sliding channel 18. According to actual needs, the designated position may be within the elastic travel of the elastic member 43 and at any position in the sliding channel 18, such as the first position in the above-mentioned embodiment, any position in the first area, or any position in the second area.

[0047] The elastic member 43 can be a spring, and can be further selected as a drum spring. There can be multiple elastic members 43. In order to ensure the stability of the multiple springs pulling the webbing 42, the spring and the webbing 42 themselves can be connected through a connecting piece 44, that is, the first end of the spring is connected to the sliding seat 61, the second end of the spring is connected to the connecting piece 44, and the second end of the webbing 42 is also connected to the connecting piece 44.

[0048] In one embodiment, the housing 1 includes a first panel 13 , and a support area 131 is formed on a surface of the first panel 13 .

[0049] In actual application scenarios, the fitness puller provided in the embodiment of the present application can have multiple usage states. In the first usage state, the user can use a part of the body to abut against the support area 131 of the first panel 13, and then hold the pull rope 2 to perform pulling exercises. The body parts used to abut against the support area 131 include but are not limited to: feet, buttocks, waist, etc., which will not be described in detail below. Correspondingly, in actual operation, in order to fit the user's body parts, the support area 131 can be made into a corresponding shape. For example, the support area 131 can be a flat surface that is convenient for stepping, a cushion shape that is convenient for sitting, an arc shape that is convenient for fitting with the waist, etc., which will not be described in detail below.

[0050] In one embodiment, the side wall of the shell 1 located on the first panel 13 is connected to a positioning member 72 through an adjusting member 71. The adjusting member 71 is used to adjust the extension distance of the positioning member 72 relative to the shell 1. The positioning member 72 is used to clamp the shell 1 between two designated support surfaces.

[0051] In another application scenario, the user can clamp the housing 1 between two designated support surfaces through the positioning member 72, wherein the designated support surface is, for example, between door frames, between two walls of a balcony, between two walls, between a cabinet and a wall, etc. The extension distance of the positioning member 72 relative to the housing 1 can be adjusted by the adjusting member 71. Usually, the user can place the fitness puller between two designated support surfaces, with the positioning member 72 facing the designated support surface, and then extend the positioning member 72 relative to the housing 1 through the adjusting member 71, so that the positioning member 72 is pressed against the surface of the designated support surface, thereby achieving fixation between the fitness puller and the designated support surface.

[0052] Furthermore, in order to facilitate installation and reduce the size of the entire fitness puller, a mounting cavity 14 for mounting the adjustment member 71 can be provided on the housing 1, and a sliding channel 18 for the sliding seat 61 to slide is formed between the two mounting cavities 14.

[0053] An opening of the installation cavity 14 faces the outside of the housing 1, and the adjustment member 71 is a linear module, which is a lead screw module. The screw is inserted into the installation cavity 14, and the end of the screw is connected to the positioning member 72. A toggle member 711 for the user to toggle is fixed on the surface of the screw. The user can toggle the toggle member 711 through the opening of the installation cavity 14 to control the extension distance of the positioning member 72 relative to the housing 1. The toggle member 711 can be a knob.

[0054] It is understandable that the linear module further includes two positioning bolts 712 , and the positioning bolts 712 penetrate and connect the positioning member 72 and the housing 1 to limit the rotation of the positioning member 72 .

[0055] In one embodiment, the positioning member 72 includes a first movable member 721 and a second movable member 722 , the first movable member 721 and the second movable member 722 are in contact with each other via a contact slope, the first movable member 721 is used to connect to the adjustment member 71 , and the second movable member 722 is used to abut against the support surface.

[0056] Specifically, the positioning member 72 includes a positioning seat 723, a first movable member 721 and a second movable member 722. The screw passes through the positioning seat 723 and is threadedly connected to the first movable member 721. The first movable member 721 is a connecting block with a first inclined surface. The inclined surface of the first movable member 721 faces the second movable member 722. The second movable member 722 has a second inclined surface formed on a side facing the first movable member 721. Specifically, the inclination directions of the first inclined surface and the second inclined surface are opposite. The second movable member 722 is connected to the positioning seat 723 to form an active space for the first movable member 721 to be installed. There is a gap between the inner wall of the active space and the first movable member 721, so that the first movable member 721 can be displaced to a certain extent in the active space, and a reset member is also provided in the active space. The reset member is a spring, one end of the spring abuts against the first movable member 721, and the other end of the spring abuts against the positioning seat 723. The spring is used to ensure that the first movable member 721 is always in contact with the second inclined surface and located at the center of the second inclined surface in the absence of external force.

[0057] With such a configuration, after the user has adjusted the adjustment member 71 and connected the positioning member 72 between the two designated support surfaces, when the user subsequently uses the fitness puller, the first movable member 721 will slide along the second inclined surface to a certain extent under the pull of the user, thereby improving the tightness of the connection between the positioning member 72 and the two designated support surfaces.

[0058] It is also necessary to add that the first panel 13 is provided with at least one positioning hole 15 for the tension rope 2 to pass through, and the housing 1 is also provided with a steering wheel 16 at the position of the positioning hole 15, and the tension rope 2 is connected to the rope wheel 3 through the steering wheel 16 to reduce the wear of the tension rope 2 through the steering wheel 16. A tension handle is provided at the end of the tension rope 2 located outside the housing 1, and the user can apply force to the tension rope 2 through the handle to facilitate the pulling movement. When there are two tension modules, the two tension modules can be set on the same positioning frame 11 and coaxially arranged to facilitate user use.

[0059] Furthermore, in the present application, a display screen 17 may be provided on the first panel 13, and a control chip connected to the liquid crystal screen is provided in the shell 1. The control chip controls the display screen 17 to display various parameters, including but not limited to: motion parameters, damping parameters, etc.

[0060] The damping parameters are implemented as follows:

[0061] By setting at least one of other sensors such as an infrared sensor and a travel sensor at a position of the shell 1 near the sliding seat 61, the sliding distance of the sliding seat 61 is determined by the sensor, and the corresponding tension damping parameters are converted based on the sliding distance, and the tension damping parameters are displayed on the display screen 17. Such operation can facilitate the user to adjust the tension damping parameters in a purposeful manner.

[0062] The motion parameters are implemented as follows:

[0063] By setting at least one of other sensors such as a rotation speed sensor and a travel sensor on at least one of the rope wheel 3 or the webbing wheel 41, the sensor is used to determine the rotation distance of the rope wheel 3 or the webbing wheel 41, and the rotation distance is converted into a corresponding tension value to display the user's pulling times, total pulling stroke, total pulling work, etc. In other embodiments, the sensor can also be installed on the reversing wheel, the positioning hole 15, etc., to directly detect the sliding distance of the tension rope 2, so as to convert the sliding distance into a corresponding tension value, which will not be described in detail below.
