Description

Technical Field

[0001] The utility model belongs to the technical field of horizontal bar training equipment, and in particular relates to a movable and stable horizontal bar training equipment. Background Art

[0002] When doing pull-up training exercises in physical education, it is necessary to use a horizontal bar for support. In order to meet the needs of different environments, such as when it is raining or hot and it is inconvenient to exercise outdoors, the horizontal bar training equipment needs to make position adjustments. Therefore, the current horizontal bar training equipment basically has the characteristic of being movable.

[0003] In order to ensure stability during later use, currently movable horizontal bar training equipment generally does not have rollers. The so-called movement is mainly achieved by carrying, and stability is ensured by the contact between the bottom support structure and the placement surface in the later stage. Although this method can ensure the stability of placement, it will consume a lot of physical strength during movement, especially when the moving distance is long, this disadvantage is more prominent, so there are great limitations in actual use, and there is room for improvement. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 3 The utility model provides a technical solution: a movable and stable horizontal bar training device, including a bottom plate 100. In order to ensure the best supporting effect and avoid the occurrence of tipping, vertical poles 101 are fixed at the middle position of the top of both sides of the bottom plate 100. A cross bar 102 is also arranged on the inner side of the pole 101. During exercise, the user holds the cross bar 102 with both hands to perform pull-ups to achieve the purpose of exercise. A moving mechanism is also arranged between the pole 101 and the bottom plate 100, and the moving mechanism includes:

[0024] The walking assembly is composed of a moving part and a mounting part, wherein the mounting part is movably sleeved on the outside of the vertical pole 101, and the moving part is arranged on the inside of the mounting part, and the moving part is connected with the bottom plate 100 through and through, and when the height of the mounting part changes, the moving part can be in contact with the placement surface, thereby realizing the rolling operation of the entire horizontal bar training device;

[0025] The adjusting component is composed of a clamping part and a limiting part component; the clamping part is sleeved on the vertical pole 101 and is pressed against the top end surface of the mounting part. The height of the entire walking component is adjusted by the clamping part, so that the walking component passes through the bottom end surface of the base plate 100 to complete the walking of the horizontal bar training device, or is built into the base plate 100 to achieve stable placement of the base plate 100 and the placement surface; the limiting part is fixed on the vertical pole 101, and the limiting part contacts with the bottom end surface of the mounting part to limit the height of the entire walking component moving downward, so as to avoid the walking component protruding too high from the bottom end surface of the base plate 100, which may affect the stability of the entire horizontal bar training device.

[0026] In this embodiment, preferably, the mounting portion is two connecting frame plates 200 symmetrically arranged outside the vertical pole 101, and the two connecting frame plates 200 have holes slidably sleeved outside the vertical pole 101 at the opposite ends, and the sides of the two connecting frame plates 200 are detachably fixed by bolts, thereby realizing the connection between the connecting frame plates 200 and the vertical pole 101, referring to Figure 2 The width of the middle area of ​​the connecting frame plate 200 is greater than the outer diameter of the vertical rod 101, so when the bolt is penetrated, it will not contact the connecting thread 101c. The moving part is the roller 201. A groove is provided on the inner side of the bottom end of the connecting frame plate 200. The roller 201 is built into the groove, and the roller 201 and the connecting frame plate 200 are connected by an axis through the through-through connection, so as to realize the rotation connection between the two, and ensure that the normal rotation of the roller 201 is not affected. The surface of the bottom plate 100 is provided with a roller groove 100a for the connecting frame plate 200 and the roller 201 to penetrate, and the overall rolling is realized by the roller 201 penetrating and protruding from the roller groove 100a.

[0027] In this embodiment, preferably, a connecting thread 101c is provided at the bottom of the vertical pole 101, and the abutting portion includes a abutting nut 104 arranged in the area of ​​the connecting thread 101c, and the abutting nut 104 abuts against the top surface of the connecting frame plate 200. When the entire device needs to be moved, the abutting nut 104 is rotated so that the abutting nut 104 pushes the connecting frame plate 200 toward the bottom direction of the bottom plate 100, so that the roller 201 protrudes from the outside of the roller groove 100a and contacts the placement surface, and then rolls. On the contrary, when it is not necessary to move, the abutting nut 104 is turned toward the top of the vertical pole 101. The roller 201 rotates in the same direction as the rest of the device. At this time, the roller 201 will be affected by the gravity of the entire device. Therefore, the entire walking assembly will change with the height change of the locking nut 104 until the bottom of the roller 201 is completely built into the roller groove 100a. At this time, the roller 201 only contacts the placement surface at a point where it has a tangent point with the placement surface. The contact area is small, and the entire device is heavy and will not be easily displaced. In actual use, a spring (not shown in the spring figure) can be added between the connecting frame plate 200 and the limiting convex ring 101b, thereby bouncing the entire walking assembly to achieve complete separation of the roller 201 from the placement surface.

[0028] In this embodiment, preferably, the limiting portion is a limiting convex ring 101b fixed on the bottom surface of the vertical pole 101, and the limiting convex ring 101b is in contact with the inner bottom end surface of the connecting frame plate 200, and is used to limit the descending position of the connecting frame plate 200, and provide support. When the inner bottom end surface of the connecting frame plate 200 moves to the limiting convex ring 101b, it indicates that the height of the roller 201 protruding from the outside of the bottom plate 100 is sufficient for movement.

[0029] In this embodiment, preferably, both ends of the cross bar 102 are fixed with rings 102a, and the rings 102a are slidably mounted on the vertical pole 101. Through holes 101a are equidistantly opened on the surface of the vertical pole 101, and limit pins 103 are inserted through the through holes 101a. The rings 102a overlap the limit pins 103, thereby supporting and placing the cross bar 102. At this time, normal training can be carried out through the cross bar 102.

[0030] In this embodiment, preferably, the top surface of the ring 102a is provided with at least two ball holes 102a-1 symmetrically along its own axis, and a ball 102c is placed inside the ball hole 102a-1. Part of the ball 102c passes through the bottom of the ball hole 102a-1 and protrudes into the inside of the ring 102a. The ball 102c is rollingly connected to the surface of the vertical pole 101, and the friction force during adjustment is reduced by the rolling connection between the ball 102c and the vertical pole 101. A limiting bolt 102b is also screwed into the inside of the ball hole 102a-1, and the limiting bolt 102b is fitted with the side of the ball 102c. The position of the ball 102c can be limited and installed by the limiting bolt 102b.

[0031] In this embodiment, preferably, the middle to bottom area of ​​the limiting bolt 102b is a smooth curved surface, thereby reducing the friction between the limiting bolt 102b and the ball 102c, and diagonal braces are welded on both sides of the connection between the base plate 100 and the vertical pole 101 to increase the strength of the vertical pole 101 through the diagonal braces.

[0032] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
