Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a folding fitness cannon. Background Technology

[0002] The fitness cannon is a multi-functional training device. Its core design is made of tubular rubber material, and the surface has multiple handle positions. This device combines lifting, flipping, throwing, rolling and other movements to achieve full-body compound training.

[0003] Traditional fitness cannons are mostly one-piece straight tubes, which results in a relatively limited overall grip position and angle. This limits the user's force exertion posture (muscles) and the muscles targeted during training (for example, there are significant differences in the muscle groups exerted by the overhand and underhand grips when doing pull-ups). Therefore, they cannot meet the user's training needs in practical applications, and there is an urgent need for a foldable fitness cannon. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foldable fitness cannon.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A foldable fitness cannon includes a first cylinder and a second cylinder, wherein the first cylinder and the second cylinder are connected to each other to form a complete cannon. A sliding groove is provided on one side of the first cylinder, and a connecting plate is installed in the sliding groove for limiting. One end of the connecting plate is rotatably installed with the second cylinder through a limiting pin. A plug is provided on one side of the cylinder body 2. A through hole is opened on the upper side of the plug. A limit pin is vertically installed in the through hole. Multiple limit blocks are installed on the upper and lower parts of the limit pin. The limit pin is inserted into the limit insertion hole opened on one side of the connecting plate. An annular tooth groove is provided on the inner wall of the limit insertion hole. The annular tooth groove and the limit block are engaged with each other. The limiting hole and the limiting pin are connected by a spring. When the limiting pin moves downward, the limiting block disengages from the annular tooth groove.

[0006] In addition, a preferred structure is that the upper and lower ends of the connecting plate and the insert are provided with limiting protrusions.

[0007] In addition, a preferred structure is that the top and bottom of the slide groove are provided with limiting grooves, and the two ends away from the limiting grooves are provided with limiting holes, and the limiting grooves and limiting protrusions are mutually limiting connection mechanisms.

[0008] In addition, a preferred structure is that the middle part of the insert has a notch to engage with the connecting plate, and the bottom wall of the notch has a blind groove to engage with the protrusion at the bottom of the connecting plate.

[0009] In addition, a preferred structure is that the connecting plate has a mounting groove in the middle, a plug rod is vertically installed in the mounting groove, the top of the plug rod protrudes through the connecting plate, and the bottom of the plug rod is connected to the mounting groove by a spring. A connecting rod is horizontally installed in the middle of the plug rod, and the connecting rod protrudes horizontally through the mounting groove.

[0010] Furthermore, a preferred configuration is that, in its natural state, the insertion rod is inserted into the limiting hole.

[0011] In addition, the preferred structure is that the middle of the first cylinder and the second cylinder are hollow, and each cylinder is provided with a mounting seat on one side of the inner wall of the first cylinder and the second cylinder. The mounting seat has a through hole in the middle, and a rubber rod is inserted between each mounting seat. The two ends of the rubber rod are set as thick ends.

A hinge structure consisting of a connecting plate and a plug is provided between the first cylinder and the second cylinder to achieve relative rotation. A press-to-unlock limit pin locking mechanism is provided in the plug assembly to realize the locking function of the hinge structure. This not only realizes the folding function of the fitness cannon barrel, but also ensures the stability after folding, meeting the usage requirements while ensuring structural stability.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-10 A foldable fitness cannon includes a cylinder body 1 and a cylinder body 2, wherein the cylinder body 1 and the cylinder body 2 are connected to each other to form a cannon body as a whole. A sliding groove 6 is provided on one side of the cylinder 1. A connecting plate 3 is installed in the sliding groove 6. The connecting plate 3 can move horizontally through the sliding groove 6. One end of the connecting plate 3 is rotatably installed with the cylinder 2 through the limiting pin 22. The cylinder body 1 and cylinder body 2 are rotatably connected to achieve mutual rotational movement, thereby realizing the adjustment operation of rotation and folding.

[0017] Handles are still provided on cylinder 1 and cylinder 2 for operators to grip.

[0018] When cylinder body 1 and cylinder body 2 are connected to form a complete barrel, the end faces of cylinder body 1 and cylinder body 2 are in contact.

[0019] A plug 21 is provided on one side of the cylinder 2, and the plug 21 protrudes from the outer wall of the cylinder 2. A through hole is provided on one side of the upper part of the insert 21. A limit pin 22 is vertically installed in the through hole, and the limit pin 22 achieves vertical displacement through the through hole. A horizontal bar is provided at the top of the limiting pin 22. The horizontal bar is parallel to the limiting protrusion 5 provided on the upper part of the insert block 21. The horizontal bar and the limiting groove 61 are interlocked. The horizontal bar is installed in the through hole to limit the pin 22 and realize the single vertical movement of the limiting pin 22.

[0020] Multiple limit blocks 221 are installed on both the upper and lower parts of the limit pin 22, and the limit blocks 221 are toothed. The limiting pin 22 is inserted into the limiting hole 8 opened on one side of the connecting plate 3. The inner wall of the limiting hole 8 is provided with an annular toothed groove 81. The annular toothed groove 81 and the limiting block 221 are engaged with each other, thereby achieving the rotation locking effect of the cylinder 2.

[0021] The limiting hole 8 and the limiting pin 22 are connected by a spring 9. When the limiting pin 22 moves downward, the limiting block 221 disengages from the annular tooth groove 81.

[0022] Limiting protrusions 5 are provided at the upper and lower ends of the connecting plate 3 and the insert block 21.

[0023] Limiting grooves 61 are provided at the top and bottom of the slide 6, and limiting holes 62 are provided at both ends away from the limiting grooves 61. The limiting grooves 61 and the limiting protrusions 5 are mutually limiting connection mechanisms.

[0024] The insert 21 has a notch in the middle to engage with the connecting plate 3, and a blind groove is provided on the bottom wall of the notch to engage with the protrusion at the bottom of the connecting plate 3, forming the bottom rotation support point of the insert 21 and the connecting plate 3.

[0025] The connecting plate 3 and the insert block 21 are connected to form a hinge-like mechanism.

[0026] A mounting groove 31 is provided in the middle of the connecting plate 3. A rod 32 is vertically installed in the mounting groove 31. The top of the rod 32 extends out of the connecting plate 3, and the bottom is connected to the mounting groove 31 by a spring 7. A connecting rod 33 is horizontally installed in the middle of the rod 32. The connecting rod 33 extends horizontally out of the mounting groove 31.

[0027] In its natural state, the insertion rod 32 is inserted into the limiting hole 62, thereby realizing the lateral locking function of the connecting plate 3.

[0028] Both cylinder 1 and cylinder 2 are hollow in the middle, and each cylinder 1 and cylinder 2 is provided with a mounting seat 41 on one side of its inner wall. The mounting seat 41 has a through hole in the middle, and a rubber rod 4 is inserted between each mounting seat 41. The two ends of the rubber rod 4 are thick ends, that is, the diameter of the ends is larger than the diameter of the rod body, so as to achieve the effect of preventing it from falling off.

[0029] The rubber rod 4 and the mounting base 41 can move relative to each other; The rubber rod 4 is symmetrically positioned with the connecting plate 3. The rubber rod 4 is elastic and generates a certain rebound force after bending, and also plays a certain supporting role.

[0030] In this embodiment, during the folding and adjustment of the fitness cannon barrel, by pinching the connecting rod 33 on the connecting plate 3 on one side of the barrel body 1 with your fingers, the connecting rod 33 moves inward and simultaneously drives the insertion rod 32 to disengage from the limiting insertion hole 8 on the inner wall of the slide groove 6. At this time, the connecting plate 3 can realize the function of lateral movement.

[0031] When the insertion rod 32 is connected to the limiting insertion hole 8, the cylinder body 1 and the cylinder body 2 cannot move relative to each other, and the connecting plate 3 cannot move due to the locking restriction of the insertion hole.

[0032] Next, pull out the second cylinder 2 to simultaneously drive the insert block 21 and the connecting plate 3 to move laterally. When the limiting protrusions 5 set at the upper and lower ends of the insert block 21 are disengaged from the limiting groove 61 on the inner wall of the slide groove 6, the insert block 21 is no longer restricted by the groove. Furthermore, when the connecting plate 3 moves laterally to the corresponding position, the insertion rod 32 on the upper part of the connecting plate 3 rebounds and is inserted into the limiting insertion hole 8 at the other end of the inner wall of the slide groove 6 under the action of the spring 7. At this time, the cylinder 1 and the cylinder 2 are pulled apart and a certain distance is left between them.

[0033] Then, the limiting pin 22 on the upper part of the insert 21 is pressed down until the limiting block 221 in the middle of the limiting pin 22 disengages from the annular tooth groove 81 on the inner wall of the limiting insertion hole 8 on the outer side of the connecting plate 3. At this time, the limiting block 221 no longer contacts the annular tooth groove 81, and the insert 21 can drive the limiting pin 22 to fold and rotate at a certain angle.

[0034] After rotating to a certain angle, the limiting pin 22 is released so that it is reset to the top by the spring 29, and then re-engaged into the annular toothed groove 81 at the corresponding position by the limiting block 221, thus completing the engagement of the limiting block 221 and the annular toothed groove 81. At this time, when the insert block 21 rotates, the limiting block 221 and the annular toothed groove 81 will mesh and lock together to limit the rotation.

[0035] During the docking process between the limiting block 221 and the annular toothed groove 81, if the limiting block 221 is stuck on the non-toothed surface of the annular toothed groove 81, the insert block 21 can be slightly shaken and rotated at any angle, so that under the return action of the spring 9, the limiting block 221 will adaptively insert into the toothed groove of the annular toothed groove 81. This is easy to understand intuitively and will not be explained further.

[0036] The annular tooth groove 81 has a tooth groove structure that is annular.

[0037] After folding and adjusting, the gripping position and angle of the cylinder body 1 and cylinder body 2 are changed. Compared with the whole barrel in its natural state, the folded barrel achieves different muscle exertion postures with different "V" shaped angles.

[0038] As the cylinder 1 and cylinder 2 are folded and adjusted, the rubber rod 4 is stretched on both sides, and the rubber rod 4 slides in the mounting base 41 to adaptively adjust the distance. The rubber rod 4, specifically made of TPU, has a certain supporting strength and flexibility. After being bent under force, the rebound force generated "tightens" the cylinder 1 and cylinder 2, and provides support on the inner wall side of the cylinder 1 and cylinder 2.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
