Description

Technical Field

[0001] This invention relates to the field of sports and training equipment, specifically to a handle and connecting buckle assembly, a handle and handle connecting tube assembly, and a comprehensive fitness board. Background Technology

[0002] With rapid societal development, fast-paced lifestyles, high work pressure, and limited free time have become the norm, resulting in insufficient time for people to exercise in gyms or other dedicated facilities, severely impacting their physical and mental health. To address these issues, the applicant has applied for multiple patents (202020721314.1, 201920742614.5, 201920746714.5, 201720049528.7, etc.), adhering to scientific training theories and the concept of "fitness anytime, anywhere, using fragmented time." Employing a minimalist and highly practical design, it integrates the functions of over 90% of current home fitness products on the market. It features a simple structure, diverse functions, compact portability, space-saving design, and wide applicability, effectively solving problems such as the severe homogenization, low practicality, limited functionality, cluttered placement, and large footprint of current home fitness equipment. However, the handle structure in the applicant's previous patent application was relatively simple, lacking the combination of handle and handle connecting tube or handle and connecting buckle, resulting in low mobility. Summary of the Invention

[0003] Purpose of the invention: The purpose of this invention is to solve the technical problem of low mobility in the prior art, and to provide a handle and connecting buckle assembly, a handle and handle connecting tube assembly, and a comprehensive fitness board.

[0004] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0005] A handle and a connecting buckle assembly includes a handle and a connecting buckle. The handle includes a grip portion connected to a first mating portion for engaging with the connecting buckle. A reset mechanism is provided on the first mating portion. The connecting buckle includes a buckle ring connected to a second mating portion for engaging with the first mating portion. The first mating portion includes a locking mechanism. When the second mating portion engages with the first mating portion through the locking mechanism, the reset mechanism can lock the two mating portions together.

[0006] Furthermore, the first docking part is a first insertion post, and the first insertion post has a cavity inside for the second docking part to be inserted and for accommodating the reset mechanism. The engaging mechanism includes a connecting buckle insertion channel disposed inside the first insertion post and arranged axially along the first insertion post. The connecting buckle insertion channel communicates with a connecting buckle locking area perpendicular to it. The second docking part of the connecting buckle is a second insertion post, and the second insertion post includes a second column. The side wall of the second column is provided with a second limiting protrusion that can enter the connecting buckle insertion channel and the connecting buckle locking area. Thus, when the second insertion post is inserted into the first insertion post, the second limiting protrusion will move along the connecting buckle insertion channel. When it reaches the connection point between the connecting buckle insertion channel and the connecting buckle locking area, the second insertion post is rotated so that the second limiting protrusion enters the connecting buckle locking area.

[0007] Furthermore, the locking area of ​​the connecting buckle is provided with an anti-disengagement protrusion to prevent the second limiting protrusion from disengaging. This further prevents the second limiting protrusion from disengaging from the locking area of ​​the connecting buckle.

[0008] Furthermore, the reset mechanism includes a movable member that can move within the first insertion post, a fixed member that is fixedly connected to the first insertion post, and a reset spring disposed between the fixed member and the movable member. During the docking process of the two mating parts, when the second limiting protrusion reaches the connection between the connecting buckle insertion channel and the connecting buckle locking area, the second limiting protrusion is in contact with the movable member or the second column is in contact with the movable member, and the reset spring is in a compressed state. Thus, when the second limiting protrusion enters the connection between the connecting buckle insertion channel and the connecting buckle locking area, the movable member is in a lifted state, the reset spring is in a compressed state, and then the second insertion post is rotated so that the second limiting protrusion fully enters the connecting buckle locking area. Under the action of the return force of the reset spring, the movable member will press against the second limiting protrusion or the second column, thereby locking the second limiting protrusion in the connecting buckle locking area.

[0009] Furthermore, the first insertion post has a screw post with a hole. The reset mechanism includes a second movable member that can move within the first insertion post, a second reset spring sleeved outside the second movable member, and a fixing component that can be fixedly connected to the inner hole of the screw post. The second movable member has a protrusion to prevent the second reset spring from dislodging. The fixing component includes a head for connecting to the inner hole of the screw post and a tail protruding outside the screw post. The size of the tail is larger than the diameter of the screw post. The second movable member has a cavity that can accommodate the fixing component. The top of the second movable member has an opening that matches the diameter of the screw post. During the docking process of the two mating parts, when the second limiting protrusion reaches the connection between the connecting buckle insertion channel and the connecting buckle locking area, the second limiting protrusion is in contact with the second movable member or the second post is in contact with the second movable member, and the second reset spring is in a compressed state. When the second limiting protrusion enters the connection between the connector insertion channel and the connector locking area, the second movable member is in a lifted state, the second return spring is in a compressed state, and then the second insertion post is rotated so that the second limiting protrusion fully enters the connector locking area. Under the action of the rebound force of the second return spring, the second movable member will press against the second limiting protrusion or the second post, thereby locking the second limiting protrusion in the connector locking area.

[0010] A handle and handle connecting tube assembly includes at least two handles and a handle connecting tube for connecting the two handles. The handle includes a grip portion, which is connected to a first mating portion for engaging with the handle connecting tube. A reset mechanism is provided on the first mating portion. Both ends of the handle connecting tube are provided with a locking mechanism and a reinforcing tube that can abut against the reset mechanism. When the first mating portion engages with the handle connecting tube through the locking mechanism, the reinforcing tube can cooperate with the reset mechanism to lock the first mating portion and the handle connecting tube.

[0011] Furthermore, the handle connecting tube has cavities at both ends for the insertion of the first mating part. The engaging mechanism includes an insertion channel disposed inside the cavity and arranged axially along the handle connecting tube. The insertion channel connects to a positioning groove perpendicular to it. The first mating part of the handle is a first insertion post, which includes a first column. The side wall of the first column is provided with a first limiting protrusion that can enter the insertion channel and the positioning groove. Thus, when the first insertion post is inserted into the handle connecting tube, the first limiting protrusion moves along the insertion channel. When it reaches the connection between the insertion channel and the positioning groove, the first insertion post is rotated, causing the first limiting protrusion to enter the positioning groove.

[0012] Furthermore, the positioning groove is provided with a handle-resistant anti-disengagement protrusion to prevent the first limiting protrusion from disengaging. This further prevents the first limiting protrusion from disengaging from the positioning groove.

[0013] Furthermore, the reset mechanism includes a movable component that can move within the first insertion post, a fixed component that is fixedly connected to the first insertion post, and a reset spring disposed between the fixed component and the movable component. When the handle is connected to the handle connecting tube, the first insertion post is inserted into the gap between the handle connecting tube and the reinforcing tube. When the first limiting protrusion enters the connection between the insertion channel and the positioning groove, the reinforcing tube and the movable component are in contact, and the reset spring is in a compressed state. Thus, when the first limiting protrusion enters the connection between the insertion channel and the positioning groove, the movable component is in a lifted state, and the reset spring is in a compressed state. Then, the first insertion post is rotated so that the first limiting protrusion is fully inserted into the positioning groove. Under the action of the return force of the reset spring, the movable component will press down on the reinforcing tube, causing the handle connecting tube to move in the direction of disengaging from the first insertion post. The top wall of the first limiting protrusion contacts the top wall of the positioning groove, thereby locking the first limiting protrusion in the positioning groove.

[0014] Furthermore, the first insertion post has a screw post with a hole. The reset mechanism includes a second movable member that can move within the first insertion post, a second reset spring sleeved outside the second movable member, and a fixing component that can be fixedly connected to the inner hole of the screw post. The second movable member has a protrusion to prevent the second reset spring from falling out. The fixing component includes a head for connecting to the inner hole of the screw post and a tail protruding outside the screw post. The tail is larger than the diameter of the screw post. The second movable member has a cavity that can accommodate the fixing component. The top of the second movable member has an opening that matches the diameter of the screw post. When the handle is connected to the handle connecting tube, the first insertion post is inserted into the gap between the handle connecting tube and the reinforcing tube. When the first limiting protrusion enters the connection between the insertion channel and the positioning groove, the reinforcing tube and the second movable member are in contact, and the second reset spring is in a compressed state. When the first limiting protrusion enters the connection between the insertion channel and the positioning groove, the second movable member is in a lifted state, and the second return spring is in a compressed state. Then, the first insertion post is rotated so that the first limiting protrusion is fully inserted into the positioning groove. Under the action of the rebound force of the second return spring, the second movable member will press down on the reinforcing tube, causing the handle connecting tube to move in the direction of disengaging from the first insertion post. The top wall of the first limiting protrusion contacts the top wall of the positioning groove, thereby locking the first limiting protrusion in the positioning groove.

[0015] A comprehensive fitness board includes a training board and an accessory assembly that can be stored on the training board. The accessory assembly includes the handle and connecting buckle assembly, and / or the handle and handle connecting tube assembly.

[0016] Furthermore, the training board is provided with a handle base that mates with the handle. The first mating part of the handle is a first insertion post. The handle base has a cavity for inserting the first insertion post. The cavity is provided with a vertical limiting groove arranged along the axial direction of the handle base. The vertical limiting groove connects to a horizontal limiting groove perpendicular to it. The first insertion post includes a first column. The side wall of the first column is provided with a first limiting protrusion that can enter the vertical limiting groove and the horizontal limiting groove. Thus, during the installation process, when the first insertion post is inserted into the handle base, the first limiting protrusion moves along the vertical limiting groove. When it moves to the point where the vertical limiting groove and the horizontal limiting groove connect, the first insertion post is rotated so that the first limiting protrusion fully enters the horizontal limiting groove, thereby achieving the engagement of the handle and the handle base.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] (1) The present invention provides a combination of handle and connecting buckle, a combination of handle and handle connecting tube, and a fitness board using these combinations, which increases the flexibility of movement;

[0019] (2) The combination of handle and connecting buckle provided by the present invention, through the setting of the locking mechanism and the reset mechanism inside the handle, enables the connecting buckle and handle to be further locked when they are engaged, thereby enhancing the locking effect;

[0020] (3) The combination of handle and handle connecting tube provided by the present invention, through the setting of the locking mechanism in the handle connecting tube, the reinforcing tube and the reset mechanism in the handle, can further achieve locking and enhance the locking effect when the handle connecting tube and handle are connected and locked.

[0067] Example 1:

[0068] This embodiment discloses a handle and connecting buckle assembly, as shown in the attached figure. Figure 12 , 14 As shown in Figures 25 and 26, the handle 4 includes a grip tube 402 for holding, which is connected to the first insertion post 7 via handle support arms 401 on both sides. The connecting buckle 6 includes a buckle ring 602, which is connected to the second insertion post 601 for mating with the first insertion post 7. A hollow mounting cavity 701 is provided through the first insertion post 7, and a connecting buckle mounting hole 702 is provided at the end away from the handle support arm 401 to mate with the connecting buckle 6. The inner diameter of the connecting buckle mounting hole 702 is smaller than the inner diameter of the hollow mounting cavity 701, so that the hollow mounting cavity 701 and the connecting buckle mounting hole 702 form a step. The connecting buckle 6 is inserted into the first insertion post 7 through the connecting buckle mounting hole 702. The first insertion post 7 includes a locking mechanism, which includes a fastener insertion channel 703 disposed inside the first insertion post 7 and arranged axially along the first insertion post 7. The bottom of the fastener insertion channel 703 is connected to a fastener locking area 704 perpendicular to it. An anti-disengagement protrusion 705 is provided at one end of the fastener locking area 704 near the fastener insertion channel 703. There can be two fastener insertion channels 703 and two fastener locking areas 704, symmetrically arranged on the inner wall of the fastener mounting hole 702. A reset mechanism is provided on the first insertion post 7. The reset mechanism is disposed in the hollow mounting cavity 701 and can be an elastic locking component 13, as shown in the attached figure. Figure 25 and 26 As shown, the elastic locking assembly 13 includes a movable member 1301 disposed within the first insertion post 7 and movable within the hollow mounting cavity 701 of the first insertion post 7, a fixing member 1302 fixed to the upper opening of the hollow mounting cavity 701, and a return spring 1303 disposed between the fixing member 1302 and the movable member 1301. (See attached diagram) Figure 26 As shown, the movable component 1301 includes an upper component 1301a corresponding to the inner diameter of the hollow mounting cavity 701 and a lower component 1301b corresponding to the inner diameter of the connecting buckle mounting hole 702. The upper component 1301a and the fixed component 1302 each have a spring positioning hole for positioning the reset spring 1303. (See attached diagram) Figure 14 As shown, the second insertion post 601 of the connecting buckle 6 includes a second post. The end of the second post's sidewall away from the buckle ring 602 is provided with a second limiting protrusion 603 that can enter the connecting buckle insertion channel 703 and the connecting buckle locking area 704. There can be two second limiting protrusions 603, located on both sides of the second insertion post 601, corresponding to the two sets of connecting buckle insertion channels 703 and connecting buckle locking areas 704. During the docking process between the connecting buckle 6 and the handle 4, when the second limiting protrusion 603 reaches the connection point between the connecting buckle insertion channel 703 and the connecting buckle locking area 704, the second limiting protrusion 603 can be in contact with the movable member 1301, or the second post can be in contact with the movable member 1301. At this time, the return spring 1303 is in a compressed state. In the design where the second limiting protrusion 603 is in contact with the movable member 1301, when the connecting buckle 6 and the handle 4 are not aligned, the movable member 1301 partially covers the connecting buckle locking area 704, and the height of the exposed part at the bottom of the connecting buckle locking area 704 is less than the height of the second limiting protrusion 603. When the connecting buckle 6 and the handle 4 are aligned, the second limiting protrusion 603 moves along the connecting buckle insertion channel 703. When it reaches the connection point between the connecting buckle insertion channel 703 and the connecting buckle locking area 704, the second limiting protrusion 603 or the second post will lift the movable member 1301, and then rotate the second insertion post 601 so that the second limiting protrusion 603 fully enters the connecting buckle locking area 704. Under the rebound force of the return spring 1303, the movable member 1301 will press against the second limiting protrusion 603 or the second post. In addition, the anti-detachment protrusion 705 will block the second limiting protrusion 603, so that the second limiting protrusion 603 can be fixed in the connecting buckle locking area 704 and will not fall off by itself. When the connecting buckle 6 is disassembled from the handle 4, simply push the connecting buckle 6 upward to lift the movable part 1301, so that the height of the second limiting protrusion 603 is greater than that of the anti-detachment protrusion 705, then rotate the second insertion post 601 so that the second limiting protrusion 603 enters the connecting buckle insertion channel 703, and then pull it out.

[0069] Example 2:

[0070] This embodiment discloses a handle and a handle connecting tube assembly, as shown in the attached figure. Figure 17 , 24 As shown in Figure 26, the handle 4 includes a grip tube 402 for holding, which is connected to the first insertion post 7 via handle support arms 401 on both sides. Both ends of the handle connecting tube 16 are used to connect to the handle 4. The handle connecting tube 16 includes an outer tube with a cavity extending through it, and a reinforcing tube 1604 inside the cavity, as shown in the attached figure. Figure 30 As shown, the reinforcing tube 1604 is fixedly connected to the outer wall of the handle connecting tube 16 at the middle position, and the length of the reinforcing tube 1604 is shorter than the length of the outer tube of the handle connecting tube 16, so that the reinforcing tube 1604 can be seen from both ends of the outer tube of the handle connecting tube 16. (See attached diagram) Figure 24 As shown, both ends of the outer tube of the handle connecting tube 16 are provided with locking mechanisms. Each locking mechanism includes an insertion channel 1601 located inside the cavity and axially aligned with the outer tube of the handle connecting tube 16. The insertion channel 1601 connects to a positioning groove 1602 perpendicular to it. A handle anti-detachment protrusion 1603 is provided at one end of the positioning groove 1602 near the insertion channel 1601. There can be two insertion channels 1601 and two positioning grooves 1602, located on both sides of the outer tube wall of the handle connecting tube 16. The first insertion post 7 of the handle 4 includes a first column. The side wall of the first column is provided with a first limiting protrusion 12 capable of entering the insertion channel 1601 and the positioning groove 1602. A hollow mounting cavity 701 is provided through the first insertion post 7. A hole 702 is provided inwardly at the end away from the handle support arm 401. The inner diameter of the hole 702 is smaller than the inner diameter of the hollow mounting cavity 701, creating a step between the hollow mounting cavity 701 and the hole 702. A reset mechanism is provided on the first insertion post 7. This reset mechanism is located inside the hollow mounting cavity 701 and can employ an elastic locking component 13, as shown in the attached figure. Figure 25 and 26 As shown, the elastic locking assembly 13 includes a movable member 1301 disposed within the first insertion post 7 and movable within the hollow mounting cavity 701 of the first insertion post 7, a fixing member 1302 fixed to the upper opening of the hollow mounting cavity 701, and a return spring 1303 disposed between the fixing member 1302 and the movable member 1301. (See attached diagram) Figure 26As shown, the movable component 1301 includes an upper component 1301a corresponding to the inner diameter of the hollow mounting cavity 701 and a lower component 1301b corresponding to the inner diameter of the hole 702. The upper component 1301a and the fixed component 1302 are each provided with a spring positioning hole for positioning the reset spring 1303. When the handle 4 is connected to the handle connecting tube 16, the first insertion post 7 of the handle 4 is inserted into the outer tube of the handle connecting tube 16. The first limiting protrusion 12 moves along the insertion channel 1601. When it moves to the connection between the insertion channel 1601 and the positioning groove 1602, the reinforcing tube 1604 will lift the movable part 1301 in the first insertion post 7. Then, the first insertion post 7 is rotated so that the first limiting protrusion 12 is fully inserted into the positioning groove 1602. Under the action of the return spring 1303, the movable part 1301 will press down on the reinforcing tube 1604, so that the handle connecting tube 16 moves in the direction of disengaging from the first insertion post 7. The top wall of the first limiting protrusion 12 contacts the top wall of the positioning groove 1602 and will not fall off by itself under the obstruction of the handle anti-disengagement protrusion 1603. When the handle 4 is disassembled from the handle connecting tube 16, simply push the handle connecting tube 16 upward or press the handle 4 downward, then rotate the first insertion post 7 so that it can pass over the handle anti-disengagement protrusion 1603 and enter the insertion channel 1601, and then pull it out.

[0071] Example 3:

[0072] In this specific embodiment, the handle 4 in all embodiments can have a second structure. Specifically, the first insertion post 7 and the reset mechanism in the handle 4 can have a second structure. (See attached...) Figure 31 As shown, the reset mechanism can employ another elastic locking assembly, which includes a second movable member 706, a second reset spring 707, and a screw 708. The second reset spring 707 is sleeved on the second movable member 706. The bottom of the second movable member 706 has a protrusion 7061 to prevent the second reset spring 707 from dislodging. The second movable member 706 has a cavity whose diameter is greater than or equal to the diameter of the tail 7081 of the screw 708, thereby accommodating the screw 708. Figure 35 As shown in the attached document. Figure 32-35 As shown, corresponding to the reset mechanism, the first insertion post 7 has a screw post 709 at its top. The screw post 709 has a threaded hole that matches the screw 708. The diameter of the screw post 709 is smaller than the diameter of the tail 7081 of the screw 708, allowing the tail 7081 to protrude outwards when the screw 708 is inserted into the screw post 709.

[0076] Combined with appendix Figure 1 , 3 12, 14, 15, 16, 24. In this embodiment, the accessory assembly includes a handle 4, an elastic rope 5, a connecting buckle 6, a combined crossbar 15, and a handle connecting tube 16. (See attached...) Figure 12 As shown, the handle 4 includes a grip tube 402 for holding, which is connected to the first insertion post 7 via handle support arms 401 on both sides. (See attached diagram) Figure 1 As shown, handle bases 8 are provided on the first unit plate 101 and the fourth unit plate 104, and are detachably connected to the first insertion post 7. The handle bases 8 can also be provided on other unit plates as needed. (See attached diagram.) Figure 11 The handle base 8 includes a first insertion hole structure 801 disposed on the unit plate. The first insertion hole structure 801 includes a main insertion hole 801a. Several pairs of angle limiting grooves 801b are provided at intervals on the side wall of the main insertion hole 801a. The first insertion post 7 is inserted into the main insertion hole 801a. The first insertion post 7 includes a first post body. The side wall of the first post body is provided with a first limiting protrusion 12. The first limiting protrusion 12 can be inserted into a specific angle limiting groove 801b as needed, so that the handle 4 can present different angles when inserted into the handle base 8. Figure 19-21In this embodiment, three pairs of angle limiting grooves 801b are provided, so that the handle 4 has three tilt angles, which can be used for different types of push-ups, sit-ups and other training. The first insertion hole structure 801 also includes a first rotation limiting groove 802, which includes a vertical limiting groove 802a that is connected to the bottom of the angle limiting groove 801b and is arranged along the axial direction of the handle base 8. The vertical limiting groove 802a is connected to a horizontal limiting groove 802b that is perpendicular to it. When handle 4 is connected to handle base 8, the first limiting protrusion 12 on the side wall of the first insertion post 7 enters the vertical limiting groove 802a through the angle limiting groove 801b. When it reaches the connection point between the vertical limiting groove 802a and the horizontal limiting groove 802b, the first insertion post 7 is rotated, causing the first limiting protrusion 12 to enter the horizontal limiting groove 802b. At this point, when handle 4 is pulled outwards, the top of the first limiting protrusion 12 abuts against the top of the horizontal limiting groove 802b, preventing handle 4 from being pulled out. When handle 4 is disassembled from handle base 8, the first insertion post 7 is rotated, causing the first limiting protrusion 12 to enter the vertical limiting groove 802a, and then handle 4 is pulled out through the angle limiting groove 801b. (Appendix) Figure 19-21 These are diagrams showing the three installation states of handle 4, with attached... Figure 19 This is the state where the first limiting protrusion 12 reaches the transverse positioning groove 802b, at which point the grip tube 402 and the front end of the training plate 1 are parallel. (See attached...) Figure 13 , 19 -20, the handle base 8 also includes a side handle base 803, which has several trapezoidal teeth 804 that can be detachably inserted into the corresponding sockets 32 on both sides of the unit plate, as shown in the attached figure. Figure 1 As shown. The side handle base 803 can be provided with a second insertion hole that is the same as the first insertion hole structure 801, or it can be provided with a second insertion hole that only has an angle limiting groove, or it can be provided with a second insertion hole that only has an angle limiting groove and a vertical limiting groove. By installing the handle 4 onto the side handle base 803, the spacing between the handles 4 can be increased.
