[0002] The application range of strength training equipment is very wide, and it can provide users with a variety of training modes according to the training devices equipped.

[0003] In the related technologies of strength training equipment, the winding wheel is a component of the resistance device, which is used to adjust and manage the transmission of resistance. The winding wheel and the resistance source are both installed on a fixed seat, and the winding wheel is connected to the resistance source through the fixed seat, and the fixed seat is connected to the frame of the strength training equipment. However, due to the low structural strength of the fixed seat, the fixed seat (during the assembly process and in use) is prone to deformation, and the winding wheel does not rotate smoothly. At the same time, due to the uneven gap between the winding wheel and the fixed seat, the problems of winding wheel friction and rope slippage occur. Utility Model Content

[0004] The purpose of the embodiments of the utility model is to provide a reel mounting seat, a resistance device and a strength training device to solve the problem that the seat body has low structural strength and provides weak protection for the winding reel.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] In a first aspect, a reel mounting seat is provided, which is applied to a resistance device, comprising:

[0007] The seat body is provided with a through receiving cavity, the receiving cavity is configured to provide a space for accommodating and rotating the winding wheel, and in the case where the winding wheel is arranged in the receiving cavity, the seat body is axially distributed on the outer periphery of the winding wheel, and the seat body is provided with a rope outlet communicating with the receiving cavity;

[0008] The seat body is provided with support parts at opposite ends of the receiving cavity, and the support parts are used to support the resistance source and / or the winding wheel.

[0009] The reel can be completely placed in the receiving cavity, and the seat body protects the entire reel, reduces the impact of the external environment on the reel, ensures smooth rotation of the reel and reduces the risk of rope slipping;

[0010] At the same time, the cooperation between the cylindrical seat body and the support parts at both ends can effectively improve the structural strength of the seat body and reduce the deformation caused by the interaction force between the resistance source and the strength training equipment. After the seat body and the resistance source are installed, or the resistance source and the winding wheel are installed with the seat body respectively, it can ensure that the coaxiality of the winding wheel with the power output shaft during the rotation process, the gap between the outer periphery of the winding wheel and the wall of the receiving cavity remains basically constant, avoiding friction between the winding wheel and the wall of the receiving cavity, and the situation where the pull rope wound on the winding wheel is detached from the winding wheel.

[0011] As an optional implementation, the rope outlet is opened between two opposite ends of the seat body along the axial direction.

[0012] Both opposite ends of the rope outlet have reinforcement structures formed by the seat body, which can effectively improve the structural strength of the seat body.

[0013] As an optional implementation, the seat body is a cylindrical structure.

[0014] Improving the structural matching degree between the seat body and the winding wheel makes the structure of the reel mounting seat more compact and stable, which is conducive to the integrated and miniaturized design of the reel mounting seat.

[0015] As an optional implementation, a connection structure is provided at the first end of the seat body, and the connection structure is used to provide an installation position for the resistance source.

[0018] The connecting plate is formed with a first opening communicating with the receiving cavity, and the connecting plate is formed with the connecting structure surrounding the first opening.

[0019] When the reel mounting seat is used in the resistance device, it ensures that the resistance source can maintain effective connection with the winding reel while making the assembly strength of the resistance source and the seat body higher.

[0020] As an optional embodiment, a support structure is provided at the second end of the seat body, and the support structure is used to provide a resistance source or a supporting position of the winding wheel.

[0022] As an optional implementation, the support structure is connected to the cavity wall of the seat body through the periphery.

[0023] Ensure that the support structure maintains a high degree of coaxiality with the seat body when supporting the resistance source or winding reel.

[0024] In a second aspect, a resistance device is provided, comprising:

[0025] The reel mounting seat as described in the first aspect;

[0026] A winding wheel, used to provide a winding position for the pull rope, the winding wheel is rotatably arranged in the receiving cavity, and when the pull rope is wound on the winding wheel, the pull rope passes through the rope outlet and out of the outside of the mounting seat;

[0027] A resistance source is installed on the seat body and acts on the winding wheel. The resistance source is used to continuously apply a force in a winding direction to the winding wheel.

[0028] The resistance source and the winding wheel are both mounted on the seat body, thereby improving the structural compactness of the resistance device, which is beneficial to the integrated and miniaturized design of the device.

[0029] As an optional embodiment, the seat body is coaxially arranged with the winding wheel so that a uniform gap is formed in the circumferential direction between the cavity wall of the accommodating cavity and the outer peripheral surface of the winding wheel.

[0030] It effectively protects the reel and reduces the occurrence of rope slipping.

[0031] As an optional embodiment, the winding wheel includes a cylinder and limit plates arranged at opposite ends of the cylinder, and a receiving groove for receiving the pull rope is formed between the limit plates and the cylinder;

[0032] The cavity wall of the receiving cavity is spaced apart from the limiting plate, and the distance between the cavity wall of the receiving cavity and the outer periphery of the limiting plate is smaller than the diameter of the pull rope wound around the cylinder.

[0033] This prevents the pull rope from being difficult to escape from the constraints of the mounting groove even when it is detached from the winding wheel, ensures that the pull rope can be in a state of being wound on the winding wheel, and ensures that the wire pulling mechanism can stably provide the functions of winding and unwinding the pull rope.

[0034] As an optional embodiment, a connecting plate as one of the supporting parts is disposed at the first end of the seat body, the connecting plate is provided with a first opening communicating with the receiving cavity, and the connecting plate is formed with a connecting structure surrounding the first opening;

[0035] The resistance source is a motor, the housing of the motor is fixedly mounted on the connecting plate through the connecting structure, and the output shaft of the motor extends into the receiving cavity through the first opening and is coaxially connected to the winding wheel.

[0036] On the premise of ensuring that the motor as the resistance source is stably connected to the seat body, it is ensured that the resistance source can continuously act on the winding wheel to provide stable resistance for the corresponding training items.

[0037] As an optional embodiment, the second end of the seat body is provided with a support cover as another support portion, and a bearing is installed on the support cover;

[0039] One end of the winding wheel away from the motor is rotatably connected to the support cover through the bearing.

[0040] This ensures that the winding wheel rotates smoothly while reducing the risk of interference between the winding wheel or the pull rope and the seat body.

[0042] Racks; and

[0043] As in the resistance device described in the second aspect, a connecting seat is convexly provided on one side of the seat body, and the resistance device is installed on the frame through the connecting seat.

[0044] By adopting the resistance device in the second aspect, the strength training equipment can stably provide corresponding training functions, extend the service life of the equipment, and reduce the risk of injury to the trainee.

[0045] The beneficial effects of the utility model are as follows: the reel mounting seat accommodates the winding wheel through the seat body, so that the winding wheel is completely placed in the accommodating cavity, and the seat body plays a role in protecting the winding wheel as a whole, reducing the influence of external foreign matter such as dust on the winding wheel, and ensuring the smooth rotation of the winding wheel. At the same time, the seat body can constrain the pull rope to a certain extent around the winding wheel, and limit the pull rope between the limiter and the winding wheel to avoid the rope from falling off;

[0046] The seat body is arranged in a structural form distributed axially on the outer periphery of the winding wheel, and mounting parts are arranged at both ends of the seat body. This can effectively improve the structural strength of the seat body and reduce the deformation of the seat body when it is subjected to the force generated by the resistance source and the strength training equipment. This allows the seat body to resist certain radial, circumferential and other directions of torque, ensure a high degree of matching accuracy between the cavity wall of the receiving cavity and the winding wheel, avoid friction between the winding wheel and the cavity wall of the receiving cavity, and avoid the pull rope wound on the winding wheel from detaching from the winding wheel, thereby ensuring that the strength training equipment can operate effectively and smoothly and reducing the risk of equipment damage and user injury.

DETAILED DESCRIPTION

[0054] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model are further described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0055] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0057] The application range of strength training equipment is very wide. It can provide users with a variety of training modes according to the training devices it is equipped with. Among them, the resistance source and the winding wheel each play an indispensable role in the strength training equipment, and together provide the trainer with an effective strength training experience.

[0058] The resistance source is the core part of the strength training equipment that provides resistance. Its function is to generate resistance that is opposite to the muscle contraction of the trainee. Common resistance sources provide resistance in ways that include but are not limited to gravity, springs, air pressure or electromagnetism. Strength training equipment can be selected according to the training programs it can provide. This article will not elaborate on this in detail.

[0059] The cable reel is a key mechanical component in strength training equipment. It connects the resistance source with the trainer's movements by winding the rope, thereby realizing the transmission and adjustment of resistance and better adapting to different training intensities and rhythms.

[0060] From the background technology, it can be known that in order to achieve effective installation of the resistance source and the winding wheel on the strength training equipment, the winding wheel and the resistance source are both installed on a fixed seat, or only the winding wheel is installed on the fixed seat, the winding wheel is connected to the resistance source through the fixed seat, and the fixed seat is installed on the frame of the strength training equipment. However, due to the low structural strength of the fixing seat provided by the relevant technology (generally an open structure and a split structure), the fixing seat is easily deformed during the assembly process due to the influence of factors such as the dimensional errors between the components, the interaction forces generated between the components, and the interaction forces between the resistance source and the frame of the strength training equipment in subsequent use. While the resistance source applies resistance to the winding wheel, the resistance source itself and the winding wheel will also transmit the relative force to the frame through the fixing seat, thereby generating torque in the corresponding direction on the relevant components of the fixing seat. The deformation of the fixing seat will cause uneven gaps between the winding wheel and the fixing seat, causing friction between the winding wheel and the fixing seat and causing problems with rotation. At the same time, the pull rope wrapped around the winding wheel will also be at risk of coming off, affecting the normal use of the strength training equipment and increasing the possibility of injury to the trainee.

[0061] To this end, the present embodiment provides a reel mounting seat, which improves the structural strength of the seat body by adopting an integrated seat body in conjunction with mounting parts arranged on both sides of the seat body, thereby providing more effective protection and restraint for the winding reel as a whole, and solving a series of problems caused by the low rigidity of the seat body (the fixed seat mentioned above).

[0062] Please refer to the attached Figure 1-Figure 5 The reel mounting seat includes a seat body 10 and a winding wheel 20, wherein the seat body 10 is used as the supporting body of the reel mounting seat, and a through receiving cavity 11 is arranged inside the seat body 10, and the receiving cavity 11 can provide a corresponding accommodation space for the winding wheel 20, and when the winding wheel 20 is placed in the receiving cavity 11, the winding wheel 20 can rotate relative to the seat body 10, that is, the seat body 10 is roughly a cylindrical structure with openings at both ends connected to the internal receiving cavity 11, so that the seat body 10 can be distributed axially on the outer periphery of the winding wheel 20, providing corresponding protection for the winding wheel 20. In addition, a rope outlet 12 connected to the receiving cavity 11 is also provided on a side portion of the seat body 10 between the positions of the openings at both ends. It can be understood that the cylindrical structure refers to the structural form of the main body of the seat body 10 in the form of a cylindrical or polygonal cylindrical structure, which has certain spatial continuity and geometric symmetry, and the structure is relatively stable and has good structural strength.

[0063] In one embodiment, the seat body 10 is an integral piece, which may be formed by an integral molding process. It should be explained that the integral piece may bring significant benefits in the following aspects in the application of the wire wheel mounting seat:

[0064] First, the one-piece molding of the seat body 10 can effectively improve the accuracy and structural strength of the seat body 10. The one-piece molding process adopts a direct molding process to avoid the errors and deformations that may exist in the traditional processing process, thereby improving the accuracy of the product. At the same time, the one-piece molding process can reduce the errors caused by assembly, and the structural integrity is strong, so that the overall structural strength of the seat body 10 is significantly improved.

[0065] Secondly, the one-piece molding process can significantly improve production efficiency. The one-piece molding process can complete the manufacture of the workpiece in one go, which greatly shortens the production cycle of the component compared to the fixing seat that needs to be assembled multiple times in related technologies. In addition, the one-piece molding process is highly automated, which can further reduce labor and material costs and improve production efficiency.

[0066] Finally, the one-piece molding process helps reduce manufacturing costs. The one-piece molding process can reduce post-processing steps such as welding and grinding, saving material and labor costs. At the same time, since the one-piece part reduces the number of parts required for assembly, it also reduces the overall cost.

[0067] In addition, the one-piece molding process has a wide range of applications, and can be applied to various metal and alloy materials, such as aluminum alloy, copper alloy, zinc alloy and magnesium alloy, and can produce seat bodies 10 of different structural forms and materials according to the needs of strength training equipment.

[0068] In one embodiment, in order to ensure that the seat body 10 can provide sufficient structural strength, the seat body 10 is generally manufactured using a metal one-piece molding process, and the metal one-piece molding process can be but is not limited to the following process methods: die casting, injection molding, and compression molding.

[0069] Of course, in some other embodiments, the seat body 10 may also be formed by a plastic one-piece molding process, and this embodiment does not impose a strict limitation on this.

[0070] The seat body 10 is provided with support parts at both opposite ends of the receiving cavity 11. In addition to supporting the resistance source and / or the winding wheel 20, the support parts can also cooperate with the seat body 10 to produce the following main effects on the structural strength of the seat body 10:

[0071] Increase the stability of the seat body 10: The support plate can provide additional support for both ends of the seat body 10, so that the cylindrical seat body 10 can better maintain its original shape and structure when subjected to external pressure or impact, and prevent deformation or buckling.

[0072] Disperse the force of the seat body 10: When the seat body 10 is subjected to the interaction force between the resistance source and the frame, the support parts at both ends can help the seat body 10 disperse these forces, avoid a part of the seat body 10 from being subjected to excessive torque, and reduce the possibility of local damage.

[0073] Improve the compression resistance of the seat body 10: The support plate can increase the overall compression resistance of the seat body 10. Especially when the seat body 10 needs to withstand axial pressure, the existence of the support portion can significantly improve the ability of the seat body 10 to resist pressure, thereby effectively protecting the winding wheel 20.

[0074] From the above content, it can be known that the winding wheel 20 is usually not a direct source of resistance. The winding wheel 20 is used to provide a winding position for the pull rope 30 to serve as a connecting component between the resistance source and the force-applying part for the trainee to hold. In the application of the resistance device, the winding wheel 20 is rotatably disposed in the receiving chamber 11 so that the cavity wall of the receiving chamber 11 is spaced around the outer periphery of the winding wheel 20. In this way, when the pull rope 30 is wound around the winding wheel 20, the pull rope 30 is placed between the winding wheel 20 and the cavity wall of the receiving chamber 11. It should be noted that when the pull rope 30 is wound around the winding wheel 20, since the pull rope 30 has a certain thickness, it will protrude from the surface of the winding wheel. Therefore, the distance from the wall of the accommodating cavity 11 to the surface of the winding wheel 20 for providing the corresponding winding position should be set to be larger than the thickness of the pull rope 30, thereby avoiding the problem of interference between the pull rope 30 and the wall of the accommodating cavity 11 during the rotation of the winding wheel 20, and allowing the pull rope 30 wound on the winding wheel 20 to pass through the rope outlet 12 to the outside of the seat body 10 and perform normal unwinding and winding.

[0075] The reel mounting seat adopts a cylindrical seat body 10 to improve the integrity and structural strength of the seat body 10. The seat body 10 with improved structural strength has relatively reduced deformation under stress, ensuring that the cavity wall of the receiving cavity 11 and the winding wheel 20 have a high matching accuracy, avoiding friction between the winding wheel 20 (pull rope 30) and the cavity wall of the receiving cavity 11, and avoiding the pull rope 30 wound on the winding wheel 20 from detaching from the winding wheel 20, ensuring that the strength training device can operate effectively and smoothly, reducing the risk of damage to the device and injury to the user. At the same time, the winding wheel 20 as a whole can be surrounded by the receiving cavity 11 along the circumference, so that the winding wheel 20 is isolated from the outside of the seat body 10 at all points on its circumference, playing a role in all-round protection of the winding wheel 20, and effectively reducing the impact and damage of the external environment (such as dust, other foreign matter and other parts of the strength training device, etc.) on the winding wheel 20.

[0076] Compared with the open structure in the related art, the seat body 10 provided in this embodiment adopts an integrated structure so as to be arranged around the circumference of the winding wheel 20. In addition to having a higher structural strength, it also provides a higher degree of protection for the winding wheel 20.

[0077] Compared with the split-type structure in the related art, the one-piece seat body 10 can save component processing and assembly steps accordingly, improve component production efficiency, and reduce production and processing costs. Of course, since the seat body 10 has a higher degree of integrity, its structural strength will naturally be higher than that of the fixed seat with a split structure.

[0078] In one embodiment, please continue to refer to the attached Figure 2 The rope outlet 12 is opened between the two opposite ends of the seat body 10 in the axial direction, that is, the rope outlet 12 is located between the openings at the two opposite ends of the seat body 10, and the length of the rope outlet 12 in the axial direction of the seat body 10 (see Appendix Figure 2 The axial direction indicated by the middle arrow is set to be smaller than the length dimension of the seat body 10 to ensure that both sides of the rope outlet 12 have parts of the seat body 10, thereby ensuring the structural strength of the seat body 10.

[0079] In addition, it should be noted that the width of the rope outlet 12 in the circumferential direction of the seat body 10 (see Appendix Figure 2 The width direction indicated by the middle arrow) also needs to be controlled within a reasonable range. Generally speaking, the seat body 10 needs to effectively control the width dimension of the rope outlet 12. It is only necessary to ensure that the pull rope 30 can smoothly pass through the rope outlet 12 during the unwinding and rewinding operations of the winding wheel 20, and avoid the situation where the width dimension of the rope outlet 12 is too large to affect the structural strength of the seat body 10.

[0080] Compared with the above embodiment in which the rope outlet 12 is arranged at one end of the seat body 10 in the axial direction, both ends of the seat body 10 located at the rope outlet 12 in the axial direction are connected to each other to ensure the structural strength of the seat body 10 (see attached Figure 2 ), its overall structural strength will be effectively improved, while the method of opening a rope outlet 12 at one end may cause a sharp decrease in the structural strength of one end of the seat body 10, resulting in a severe deformation of the end opening under stress, thereby affecting the matching accuracy with the winding wheel 20, causing interference between one end of the winding wheel 20 and the seat body 10, and ultimately causing a series of technical problems mentioned in the background technology.

[0081] In one embodiment, the surface of the winding wheel 20 around its rotation axis (circumferential direction) is provided with spirally arranged grooves, one end is fixed to the winding wheel 20 and is spirally accommodated in the groove along the arrangement of the groove on the winding wheel 20.

[0082] In the actual application scenario of the strength training equipment, the trainer extends the pull rope 30 out of one end of the seat body 10 to apply tension to the rope wheel, overcome the resistance applied by the resistance source to the rope wheel, pull the winding wheel 20 to rotate in the unwinding direction, and the pull rope 30 changes position along the axial direction of the winding wheel 20 on the spiral groove to achieve unwinding. When the trainer releases the pull rope 30, so that the resistance source drives the rope wheel to rotate in the winding direction, the pull rope 30 changes position along the axial direction of the winding wheel 20 on the spiral groove to achieve winding. It can be understood that when the winding wheel 20 rotates in the unwinding and winding directions, the position changes of the pull rope 30 along the axial direction of the winding wheel 20 are opposite.

[0083] According to the above embodiment, as an optional embodiment, in order to avoid the situation where the pull rope 30 interferes with the edge of the rope outlet 12 when the pull rope 30 changes its position along the axial direction of the winding wheel 20, as shown in FIG. Figure 1 , Figure 4 As shown, the rope winding wheel is consistent with the axial direction of the seat body 10, and the rope outlet 12 is arranged along the axial direction of the seat body 10, so as to achieve the effect of avoiding the displacement of the pull rope 30.

[0084] As a technical solution that can be independent of the above-mentioned embodiment or can be combined with the above-mentioned embodiment, Figure 1-Figure 5 As shown, the seat body 10 can be specifically configured as a cylindrical structure, so that the outer peripheral wall and the inner peripheral wall (the cavity wall of the receiving cavity 11 ) of the cylindrical seat body 10 are both cylindrical.

[0085] The outer peripheral wall of the seat body 10 is set to be cylindrical, which is not only conducive to the miniaturization design of the winding and lifting mechanism and saves the installation space of the wire wheel mounting seat, but also allows its structure to be adapted to the structural form of a part of the resistance source. When the resistance source is installed on the frame of the strength training equipment through the seat body 10, the seat body 10 with a cylindrical structure can effectively improve the structural integrity and compactness of the resistance device. Here, the specific implementation method for improving the structural integrity and compactness of the resistance device will be further described in detail in the subsequent content of this article, and will not be described in detail here.

[0086] The cavity wall of the receiving cavity 11 is arranged to be cylindrical, which can also be understood as that the space provided by the receiving cavity 11 is a cylindrical receiving space. The cylindrical receiving space can make the receiving cavity 11 structure better adapt to the winding wheel 20 structure, so that the outer circumferential surface of the winding wheel 20 and the cavity wall of the receiving cavity 11 are structurally matched. In this way, when the receiving cavity 11 and the winding wheel 20 are coaxially arranged, a uniform gap is formed in the circumferential direction between the cavity wall of the receiving cavity 11 and the outer circumferential surface of the winding wheel 20, thereby minimizing the waste of space in the receiving cavity 11 while effectively protecting the winding wheel 20, which is also beneficial to the constraint and restriction of the pull rope 30 and the winding wheel 20.

[0087] In addition, the cavity wall of the accommodating cavity 11 is configured to be compatible with the structure of the winding wheel 20. Even if the winding wheel 20 or the pull rope 30 interfere with the accommodating cavity 11 by friction, the friction force generated between the two will be at a relatively low level, thereby reducing the risk of the winding wheel 20 getting stuck or the rope falling off in the early stage of the reel mounting seat failure.

[0088] According to any of the above-mentioned embodiments, a connecting structure 132 is provided at the first end of the seat body 10, and the connecting structure 132 is used to provide an installation position for the resistance source, that is, in the application of the resistance device, the resistance source can be installed on the seat body 10 through the connecting structure 132, thereby improving the integrity of the resistance device.

[0089] Specifically, the connection structure 132 may be a structure integrally formed with the seat body 10 , or may be a structure fixed to the seat body 10 through a subsequent assembly process after the seat body 10 is integrally machined and formed.

[0090] In addition, the present embodiment does not have strict restrictions on the specific structural form of the connection structure 132. The connection structure 132 may be provided by a plate member disposed on the seat body 10, or by a block member disposed on the seat body 10, etc.

[0091] Please continue to refer to the attached Figure 1-Figure 2 , following the above-mentioned implementation of the connection structure 132, a connecting plate 13 can be provided at the first axial end of the seat body 10, and the connecting plate 13 serves as one of the supporting parts of the above-mentioned seat body 10. The connection structure 132 is provided by the connecting plate 13. Compared with other structural forms such as block structures, the plate structure can effectively reduce the space occupied by the accommodating cavity 11 and effectively control the overall volume of the seat body 10, which is conducive to the compact and miniaturized design of the subsequent application of the reel mounting seat in the resistance device.

[0092] Specifically, the connecting plate 13 is arranged at a position blocking a portion of the opening at the first end of the seat body 10, so that the opening at the end of the seat body 10 can still provide space for the resistance source to extend into the receiving cavity 11 and connect with the winding wheel 20, and the specific structure of the connecting plate 13 can be adaptively designed according to the cavity wall structure of the receiving cavity 11, and can also be adaptively designed according to the outer peripheral surface structure of the seat body 10.

[0093] Please continue to refer to the attached Figure 1-Figure 2 In the above-mentioned embodiment of the seat body 10 adopting a cylindrical structure, the connecting plate 13 can adopt a structure compatible with the cylindrical seat body 10, and the connecting plate 13 is arranged around the circumference of the seat body 10 at the opening of the first end of the seat body 10. Since the connecting plate 13 adopts a structure compatible with the structure of the seat body 10 in this embodiment, the structure of the connecting plate 13 can refer to the flange in the mechanical field.

[0094] Continuing from the above embodiment, in order to retain the connection position between the resistance source and the reel 20, the connecting plate 13 is formed with a first opening 131 communicating with the receiving cavity 11. The first opening 131 penetrates the connecting plate 13, and is used to provide at least a portion of the resistance source to penetrate into the receiving cavity 11 and connect to the reel 20. The connecting structure 132 is formed on the portion of the connecting plate 13 surrounding the first opening 131. In the application of the resistance device, the fixed end of the resistance source is mounted on the seat body 10 through the connecting structure 132, and the driving end of the resistance source penetrates into the receiving cavity 11 through the first opening 131 and connects to the reel 20, acting on the reel 20 to provide corresponding training resistance.

[0095] By adopting a connecting plate 13 that is structurally adapted to the seat body 10 to provide a connecting structure 132, the structural integrity of the seat body 10 can be effectively improved, allowing it to support both the resistance source and the winding wheel 20 during the application of the resistance device. At the same time, the cylindrical seat body 10 also ensures that the overall design of the resistance device is compact and miniaturized, thereby improving the efficiency of its early processing and subsequent assembly process, and correspondingly reducing the difficulty of disassembly and assembly of the resistance device.

[0096] According to any of the above technical solutions, Figure 1 , Figure 3 As shown, a support structure 151 is provided at the second end of the seat body 10. The support structure 151 is used to provide a support position for the resistance source or the winding wheel 20. The support structure 151 is connected to the cavity wall of the seat body 10 through the outer periphery, so that the stress distribution of the seat body 10 is optimized and the stress concentration phenomenon is reduced. At the same time, the force between the seat body 10 and the support structure 151 is more uniform, so that the support structure 151 can remain stable when supporting the resistance source or the winding wheel 20.

[0097] The above embodiment takes the application state of the reel mounting seat in the resistance device as an example. The reel 20 will be subjected to the interaction force of the resistance source and the pull rope 30 during training, wherein the interaction force between the two includes a part of the radial force acting on the reel 20 in the radial direction, which will cause the matching strength between the reel 20 and the seat body 10 to be tested to a certain extent. In the case where the matching strength between the reel 20 and the seat body 10 is weak, the reel 20 will have a certain risk of radial displacement relative to the seat body 10, which will eventually cause the reel 20 or the pull rope 30 to interfere with the accommodating cavity. By providing a support structure 151 at the end of the seat body 10, the end of the reel 20 can be effectively supported on the seat body 10, or, on the basis of the reel 20 being stably supported by the resistance source, the resistance source can be effectively supported by the seat body 10, thereby improving the radial stability of the reel 20 and reducing or even avoiding the above-mentioned risks.

[0098] Based on the implementation method in which a connecting structure 132 is provided at the first end of the seat body 10, the first end of the winding wheel 20 can be supported on the seat body 10 through the resistance source or the connecting structure 132, and the second end of the winding wheel 20 can be supported on the seat body 10 through the resistance source or the supporting structure 151, thereby improving the matching accuracy of the resistance source, the winding wheel 20 and the seat body 10, and making the relationship between the three tend to be stable, so as to achieve the purpose of balancing the force of the rope wheel.

[0099] It is worth mentioning that the supporting structure 151 is similar in principle to the above-mentioned connecting structure 132, and can also be provided by, but not limited to, a plate structure or a block-shaped component. Moreover, the part used to provide the supporting structure 151 can also be an integral part processed with the seat body 10 through an integral molding process, or it can be assembled through a subsequent assembly process.

[0100] Similarly, the specific structural form of the support structure 151 will be described in relatively detail later in this article, and this embodiment will not be further described here.

[0101] As an example that can be based on any of the above implementations, please refer to the attached Figure 1 The winding wheel 20 includes a cylinder 21 and limiting plates 22 arranged at opposite ends of the cylinder 21. The limiting plates 22 specifically protrude from the surface of the cylinder 21 in the circumferential direction of the cylinder 21, so that a receiving groove for receiving the pull rope 30 is formed between the limiting plates 22 and the cylinder 21.

[0102] When the winding wheel 20 is rotatably arranged in the receiving groove, the cavity wall of the receiving cavity 11 is spaced apart from the limiting plate 22, and the gap A between the cavity wall of the receiving cavity 11 and the outer periphery of the limiting plate 22 is smaller than the diameter B of the pull rope 30 wound around the cylinder 21, so that even if the pull rope 30 is out of the state of being tightly wound around the cylinder 21, it cannot be separated from the winding wheel 20 through the gap between the limiting plate 22 and the cavity wall of the receiving cavity 11, which plays a certain restraining role on the pull rope 30 and prevents it from falling off.

[0103] Please continue to refer to the attached Figure 1-Figure 5 The present embodiment also provides a resistance device. It can be understood from the above content that the reel mounting seat provided above can be applied to the resistance device. In the application of the resistance device, the resistance device includes a resistance source in addition to the reel mounting seat described above. The resistance source is installed on the seat body 10 and acts on the reel 20. The resistance source is used to continuously apply a force in the winding direction to the reel 20, so that the reel 20 has a tendency to move in the winding direction, and provides corresponding training resistance to the trainee.

[0104] It should be understood that the resistance source used by the resistance device includes but is not limited to the following methods:

[0105] Gravity resistance: The training resistance can be adjusted according to the training needs of the trainee by using weight blocks of different weights or numbers;

[0106] Spring resistance: The training resistance can be adjusted according to the training needs of the trainer by using springs of different stiffness, stretch length and quantity;

[0107] Hydraulic resistance: a method of generating resistance by flowing liquid (such as oil) in a sealed cylinder, and adjusting the flow rate of the liquid or the design of the cylinder to adjust the training resistance.

[0108] Air pressure resistance: It can generate resistance by compressing air in a sealed container, and the training resistance can be adjusted by adjusting the air flow or the volume of the container;

[0109] Magnetic resistance: uses magnets to create resistance, and the resistance can be adjusted by changing the distance between the magnet and the flywheel or the strength of the magnet;

[0110] Friction resistance: The training resistance is adjusted by increasing or decreasing the friction between moving parts.

[0111] Of course, the form of the resistance source of this embodiment is not limited to the above-mentioned method. The resistance source of this embodiment only needs to be able to continuously apply a force to the winding wheel 20 to move in the winding direction so that it has a tendency to move in the winding direction.

[0112] Please continue to refer to the attached Figure 1-Figure 2 In one embodiment, based on the implementation in which a connecting plate 13 is provided at the first end of the seat body 10 , the connecting plate 13 is provided with a first opening 131 communicating with the accommodating cavity 11 , and the connecting plate 13 is formed with a connecting structure 132 surrounding the first opening 131 .

[0113] In this embodiment, the resistance source is the motor 40. The method of using the motor 40 as the resistance source can also be understood as one of the above-mentioned magnetic resistance methods. The purpose of applying a corresponding force to the winding wheel 20 is achieved through the action of the magnetic field inside the motor 40.

[0114] Specifically, the housing of the motor 40 is fixedly mounted on the connecting plate 13 through a connecting structure 132, wherein the connecting structure 132 can be a threaded hole opened on the connecting plate 13, and the housing 41 of the motor 40 is installed on the threaded hole of the connecting plate 13 through bolts, and the motor 40 is circumferentially against the connecting plate 13 to achieve the stability of the motor 40. Of course, the specific structural form of the connecting structure 132 is not limited to this. The connection between the housing 41 of the motor 40 and the connecting plate 13 can adopt the conventional technology in the current mechanical field, and its specific connection method is not the required scope of protection of the utility model. The output shaft 42 of the motor 40 extends into the receiving cavity 11 through the first opening 131 and is coaxially connected with the winding wheel 20. It should be noted that in order for the output shaft 42 of the motor 40 to continuously provide the winding direction force for the winding wheel 20, the output shaft 42 of the motor 40 needs to be set to a relatively fixed form with the winding wheel 20, such as through interference fit, key connection and other connection methods to achieve coaxial transmission connection between the two.

[0115] In this embodiment, one end of the winding wheel 20 close to the outer casing of the motor 40 is supported by the output shaft 42 of the motor 40, or the end of the winding wheel 20 close to the outer casing of the motor 40 can also be supported by the connecting plate 13, which can be determined according to the specific design requirements of the resistance device.

[0116] In the embodiment where the support structure 151 is provided at the second end of the seat body 10 , the second end of the seat body 10 may be provided with a support cover 14 so that the bearing 15 installed on the support cover 14 provides a corresponding support structure 151 .

[0117] The support cover is another support part of the seat body 10. According to the assembly relationship between the resistance source (motor 40) and the winding wheel 20, any of the following embodiments can be selected between the resistance source, the winding wheel 20 and the seat body 10 (support cover 14):

[0118] 1. The output shaft 42 of the motor 40 is rotatably connected to the support cover 14 through the bearing 15;

[0119] 2. One end of the winding wheel 20 away from the motor 40 is rotatably connected to the support cover 14 through the bearing 15.

[0120] It is also mentioned in the above content that according to the matching structural relationship between the resistance source and the winding wheel 20, the end of the winding wheel 20 close to the second end of the seat body 10 (the end of the winding wheel 20 facing away from the resistance source) can be supported by the resistance source itself or the support structure 151.

[0121] For example, taking the motor 40 as a resistance source, when the output shaft 42 of the motor 40 passes from one end of the winding wheel 20 to the other end thereof, both opposite ends of the output shaft 42 can be supported by the output shaft 42 of the motor 40, and the end of the output shaft 42 away from the housing 41 is rotatably connected to the support cover 14 (seat body 10) through the bearing 15 to stabilize the installation state of the winding wheel 20. In this way, the support structure 151 mentioned in the above embodiment adopts the embodiment of providing the support position of the resistance source;

[0122] When the output shaft 42 does not pass through the winding wheel 20, the end of the winding wheel 20 close to the resistance source can be supported by the output shaft 42, while the end of the winding wheel 20 away from the resistance source can be supported by the support cover 14 by means of a rotational connection between the bearing 15 and the support cover 14 (seat body 10), so as to achieve the purpose of stabilizing the installation state of the winding wheel 20. In this way, the support structure 151 mentioned in the above embodiment adopts an embodiment in which it is used to provide a support position for the winding wheel 20.

[0123] This embodiment also provides a strength training device, which, in addition to adopting the resistance device provided by any of the above embodiments, also includes a frame (not shown). The frame serves as the supporting base of the strength training device. In actual application scenarios, different training devices can be installed according to the design requirements of the product and the training needs of the user to provide different training programs.

[0124] Among them, a connecting seat 16 is convexly provided on one side of the seat body 10, so that the resistance device can be installed on the frame through the connecting seat 16. The pull rope 30 extending from the seat body 10 through the rope outlet 12 can be wound around different pulleys or structural components for changing its direction, and a force-applying component is provided at its end away from the winding wheel 20, so that the trainee can hold the force-applying component and act on the winding wheel 20 through the pull rope 30, so as to overcome the resistance provided by the resistance source to the winding wheel 20 and achieve the purpose of corresponding training effect.

[0125] In summary, the strength training equipment provided by the present invention improves the stability of the equipment by adopting the resistance device provided above. The resistance device can continuously provide stable resistance during user training, ensuring the constant resistance to a certain extent, so that the training effect of the training items provided is better, while also reducing the risk of equipment damage and trainee injury, ultimately improving the user experience.
