Technical Field

[0001] This invention belongs to the field of sports training technology, specifically a multifunctional combined sports training device. Background Technology

[0002] With the rapid development of national fitness, school sports, and the professional physical training industry, the demand for various specialized sports training equipment continues to grow. Currently, most mainstream sports training equipment on the market is one-piece fixed equipment welded together. The equipment has a highly limited function, and a single piece of equipment is usually only suitable for one type of training program such as hurdles, squats, or obstacle courses. If you want to carry out diversified and comprehensive physical training, you need to purchase multiple independent pieces of equipment at the same time. This not only results in high procurement costs, but also requires a lot of indoor and outdoor space for storage and transportation. This is not very friendly to usage scenarios with limited space resources, such as school playgrounds, small fitness studios, and community sports spaces. Furthermore, one-piece equipment is bulky and heavy, making it difficult to transport over long distances. When not in use, it cannot be disassembled for storage, resulting in low space utilization. Summary of the Invention

[0005] Interlocking rods, used to assemble sports training equipment;

[0006] The splicing locking mechanism includes a connector arranged on one side of the splicing rod, which provides a connection support point for splicing multiple sets of splicing rods;

[0007] Limiting components, including locking blocks arranged on the splicing rod, are used to prevent the splicing locking mechanism from falling off.

[0008] As a further preferred embodiment of this technical solution: the splicing locking mechanism further includes:

[0009] The slot is provided on the connector to limit its movement;

[0010] The locking rod is slidably connected to the receiving cavity inside the splicing rod, and one end is snapped into the slot.

[0011] Mounting slots are provided on the splicing rods for inserting connectors.

[0014] As a further preferred embodiment of this technical solution: a notch is provided on one side of the upper end of the locking rod, and one end of the locking screw abuts in the notch at the upper end of the locking rod, so as to make the locking rod move vertically by tilting the notch.

[0015] As a further preferred embodiment of this technical solution: one end of the locking screw is spherically shaped to reduce friction with the locking rod cut.

[0016] As a further preferred embodiment of this technical solution: the splicing locking mechanism is provided in several groups, and is respectively provided at the upper and lower ends of the splicing rod, and the splicing locking mechanism is also provided on the four sides of the splicing rod.

[0023] As a further preferred embodiment of this technical solution: one end of the card block extends out to the end of the locking screw.

[0024] As a further preferred embodiment of this technical solution: the limiting groove is an annular structure and is respectively provided with corresponding locking screws.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. In this invention, splicing locking mechanisms are arranged at the top and bottom and on all four sides of the splicing rod, and slots are opened at both ends of the connector. A single connector can connect two splicing rods at the same time. The rods can be spliced ​​in any horizontal, vertical and lateral direction, and can build various shapes such as planar frames, three-dimensional multi-layer training racks, and high and low obstacle racks, to meet the different sports training needs such as hurdles, strength training and physical obstacle courses, and truly realize the multi-purpose and multi-functional combination of one device.

[0027] 2. In this invention, the end of the locking screw adopts a spherical structure, which forms a point contact with the inclined cut at the upper end of the locking rod. When rotating the screw, the frictional resistance is small, the rotation is smooth, and the parts are not easily worn. The horizontal thrust of the screw is converted into the vertical displacement of the locking rod by relying on the inclined plane transmission. The locking and disassembly of the rod can be completed by simply turning the screw, without the need for additional tools. The internal return spring can automatically drive the locking rod to return to its original position, which greatly improves the efficiency of disassembly and assembly and extends the service life of the mechanism.

[0028] 3. In this invention, the locking screw is equipped with a limiting component consisting of a compression spring and two sets of symmetrical locking blocks. The splicing rod is equipped with an annular limiting groove. Under normal conditions, the compression spring pushes the locking blocks into the limiting groove, which restricts the locking screw from vibration, loosening, and axial movement in all directions, preventing the equipment from falling apart during training. To disassemble the screw, simply press the exposed locking block to release the limiting. The assembly error tolerance is high, which effectively improves the safety of the equipment and the overall structural stability. Attached Figure Description

[0042] Example

[0043] Please see Figures 1-7 As shown, the present invention provides a technical solution: a multifunctional combined sports training device, comprising:

[0044] Splicing rod 1, used to assemble sports training equipment;

[0045] The splicing locking mechanism includes a connector 201 arranged on one side of the splicing rod 1, which is used to provide connection support points for splicing multiple sets of splicing rods 1;

[0046] The limiting component includes a locking block 301 arranged on the splicing rod 1 to prevent the splicing locking mechanism from falling off.

[0047] It should be noted that the splicing rod 1 is used as the standard assembly unit of the equipment, and the connector 201 is used to complete the docking and combination between multiple splicing rods 1; the locking block 301 limits and locks the splicing locking mechanism to prevent the locking structure from loosening and falling off under external force after assembly; through the modular basic frame, the splicing rod 1 can be freely spliced, and with the basic anti-detachment limiting structure of the locking block 301, it supports quick disassembly and assembly and stable combination, and can assemble sports training equipment of different specifications and shapes according to training needs.

[0048] In this embodiment, specifically, the splicing locking mechanism further includes: a slot 202, which is provided on the connector 201 and used to limit the connector 201; a locking rod 203, which is slidably connected in the receiving cavity inside the splicing rod 1 and has one end locked in the slot 202; a mounting groove 204, which is provided on the splicing rod 1 and used to insert the connector 201; a return spring 205, which is provided in the receiving cavity inside the splicing rod 1, with its upper end fixedly connected to the splicing rod 1 and its lower end fixedly connected to the upper end of the locking rod 203; and a locking screw 206, which is threaded through and connected to the splicing rod 1 and used to make the locking rod 203 move vertically.

[0049] The process involves inserting the connector 201 into the mounting slot 204 of the splicing rod 1 from the outside to complete the alignment; under normal conditions, the return spring 205 pulls the locking rod 203 upward, causing the bottom of the locking rod 203 to be in the unlocked state; rotating the locking screw 206 causes the screw to press the locking rod 203 inward, overcoming the elastic force of the return spring 205 and moving the locking rod 203 downward, so that the locking rod 203 is engaged with the slot 202 to complete the connection; this achieves quick and detachable locking between the splicing rod 1 and the connector 201; the locking screw 206 serves as a simple unlocking operation component, providing a secure lock and easy disassembly and assembly; this mechanism can be arranged in multiple directions on the splicing rod 1, providing a variety of splicing points for the rods.

[0050] In this embodiment, specifically: a notch is provided on one side of the upper end of the locking rod 203, and one end of the locking screw 206 abuts against the notch at the upper end of the locking rod 203, so as to make the locking rod 203 move vertically by tilting the notch.

[0051] It should also be understood that rotating the locking screw 206 causes it to feed along the thread axis, and the end of the screw continuously presses against the inclined cut of the locking rod 203. The inclined surface converts the horizontal pushing force of the locking screw 206 into a vertical lifting force, which drives the locking rod 203 to move downward and engage with the slot 202 of the connector 201 to achieve locking. The direction of force is converted by the inclined surface, and the locking rod 203 can be raised and lowered vertically by simply rotating the locking screw 206. The overall transmission structure is compact, requires no additional transmission parts, occupies little internal space of the splicing rod 1, and the unlocking operation is labor-saving.

[0052] In this embodiment, specifically, one end of the locking screw 206 is spherically shaped to reduce friction with the cut of the locking rod 203.

[0053] In addition, during the rotation and feeding of the locking screw 206, the spherical end and the inclined cut of the locking rod 203 are in point contact, and the frictional resistance is greatly reduced when the two slide relative to each other; this reduces frictional jamming when rotating the locking screw 206, making the rotation smooth and effortless; and it is less likely to wear down the cut of the locking rod 203 and the end of the locking screw 206 after repeated disassembly and assembly, thus extending the overall service life of the locking mechanism and providing a better operating feel.

[0054] In this embodiment, specifically: several sets of splicing locking mechanisms are provided, and they are respectively provided at the upper and lower ends of the splicing rod 1. The splicing locking mechanisms are also provided on the four sides of the splicing rod 1.

[0055] It should be noted that each of the six sides of the splicing rod 1, including the top, bottom, and four sides, has an independent splicing interface. Any adjacent splicing rods 1 can be connected to each other in any horizontal, vertical, or lateral direction through the splicing locking mechanism and the connector 201. There are no directional restrictions on splicing, and various shapes such as planar frames, three-dimensional multi-layer frames, and staggered training frames can be built, which greatly improves the diversity of equipment combinations and meets the needs of various sports training such as hurdles, power racks, and physical obstacles, truly realizing multi-functional combinations.

[0056] In this embodiment, specifically: each end of each connector 201 is provided with a slot 202 for splicing multiple splicing rods 1.

[0057] In this system, the two ends of a single connector 201 are respectively inserted into the mounting slots 204 of two different splicing rods 1, and the locking rods 203 on both sides are simultaneously engaged into the slots 202 at both ends of the connector 201, thus rigidly connecting the two splicing rods 1 into one unit; multiple connectors 201 can be connected in series to extend the length of the splicing rod 1 group; one connector 201 connects two splicing rods 1 at the same time, the splicing structure is stable, the extension equipment does not require additional transition accessories, the rods have high coaxiality, the overall frame is strong after splicing, and the training load-bearing stability is better.

[0058] In this embodiment, specifically: the limiting component further includes: a compression spring 302, fixedly arranged on the locking block 301, used to reset the locking block 301; a receiving groove 303, formed on the locking screw 206, used to receive the locking block 301, and the locking block 301 is slidably connected in the receiving groove 303; and a limiting groove 304, formed on the splicing rod 1, used to prevent the locking screw 206 from falling off, and one end of the locking block 301 is engaged in the limiting groove 304.

[0059] It should also be understood that the compression spring 302 normally pushes the two side blocks 301 outwards, and the blocks 301 extend out of the locking screw 206 and lock it in the limiting groove 304 of the splicing rod 1, restricting the axial movement and rotation of the locking screw 206. Only by manually pressing the two side blocks 301 to compress the compression spring 302, can the blocks 301 be removed from the limiting groove 304 and the locking screw 206 be unscrewed, thus achieving anti-dislodgement limiting. Under training vibration and external impact, the locking screw 206 will not loosen and fall off on its own, avoiding the splicing structure from falling apart. The locking screw 206 can only be disassembled by manually pressing the blocks 301, providing double safety locking and improving the safety of the equipment.

[0060] In this embodiment, specifically: the card block 301 is provided in two sets, and is respectively located at both ends of the compression spring 302 and fixedly connected to the compression spring 302.

[0061] In addition, the compression spring 302 simultaneously outputs elastic force to the left and right sides, synchronously pushing the two end blocks 301 outwards. The two end blocks 301 simultaneously engage with the limiting grooves 304, forming a symmetrical bidirectional limiting structure. The two end blocks 301 are subjected to balanced force, making it difficult for one side to dislodge from the groove. The limiting force is symmetrical, and the locking screw 206 has no radial offset, resulting in higher reliability of the limiting structure. Pressing the two end blocks 301 synchronously compresses the compression spring 302 to unlock the device, making the operation symmetrical and simple.

[0062] In this embodiment, specifically: one end of the locking block 301 extends out to one end of the locking screw 206.

[0063] The extended section of the locking block 301 is directly embedded in the limiting groove 304 on the inner wall of the splicing rod 1, forming an axial block. When the hand presses the exposed end of the protruding locking block 301, it can directly overcome the elastic force of the compression spring 302 and press the locking block 301 back into the receiving groove 303. The exposed locking block 301 is easy to operate by hand, and the limiting unlocking can be completed without auxiliary tools. The protruding structure has sufficient limiting depth, and the anti-dislodgement blocking effect is stronger.

[0064] In this embodiment, specifically: the limiting groove 304 is an annular structure, and is respectively set with the locking screw 206.

[0065] Working principle or structural principle: Using splicing rod 1 as the basic unit, multiple sets of splicing locking mechanisms are provided at the top and bottom and on all four sides of splicing rod 1. During assembly, the connector 201 with slots 202 at both ends is inserted into the mounting groove 204 on the outer wall of splicing rod 1. Under normal conditions, the return spring 205 in the cavity of splicing rod 1 pulls the locking rod 203 upward to raise it, without obstructing the insertion of the connector 201. Tightening the locking screw 206 with a ball-shaped front end makes it advance inward, and the ball-shaped end presses against the locking rod 203. The inclined cut at the end converts the horizontal thrust into a vertical downward pressure, pushing the locking rod 203 to overcome the elastic force of the return spring 205 and move downward and lock into the slot 202 of the connector 201, realizing the rigid splicing of multiple splicing rods 1 in any position. When the locking screw 206 is turned out in the opposite direction, the spherical end disengages from the cut, and the return spring 205 pulls the locking rod 203 to lift it out of the slot 202, so the connector 201 can be pulled out to complete the disassembly. The contact between the spherical end and the cut point can reduce rotational friction and reduce wear on parts.

[0066] Meanwhile, the locking screw 206 has two sets of locking blocks 301 located at both ends of the compression spring 302 in the internal receiving groove 303. The compression spring 302 normally pushes the locking blocks 301 outward, so that the end of the locking block 301 extending out of the outer wall of the locking screw 206 is engaged in the corresponding annular limiting groove 304 on the splicing rod 1. This comprehensively restricts the axial movement and self-loosening of the locking screw 206, preventing the splicing frame from falling apart due to training vibration. If the locking screw 206 needs to be disassembled, simply press the exposed locking block 301 to compress the compression spring 302, allowing the locking block 301 to retract into the receiving groove 303 and disengage from the limiting groove 304. After unlocking, the screw can be unscrewed. After releasing the locking block 301, the compression spring 302 automatically pushes the locking block 301 back to its original position to restore its limiting function. The entire structure can be freely assembled into various sports equipment such as hurdles, physical obstacles, and strength training frames. It features convenient assembly and disassembly, flexible splicing, firm locking, and safe use.
