Description

Indoor horizontal bar

Technical Field

The invention belongs to the technical field of indoor sports equipment, and particularly relates to an indoor horizontal bar.

Background

Along with the popularization of the national fitness and the pursuit of people for health, more and more people pay attention to physical exercise, but the fast-paced life cannot vacate a large time to places with more fitness equipment such as a gymnasium, and in order to build the body at any time and save the space, a wall-mounted horizontal bar appears on the market, and the wall-mounted horizontal bar achieves the effect of being mountable anywhere by locking two ends on the wall and occupies small space. However, in the using process, due to the fact that the body moves up and down and swings back and forth, non-directional inertia is generated, if the weight of a user is too heavy, the horizontal bar can slide relative to the wall and fall off, and potential safety hazards exist.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides the indoor horizontal bar which is simple to assemble and high in use safety.

The technical scheme adopted by the invention for solving the technical problems is as follows: an indoor horizontal bar comprises a horizontal bar mechanism with a horizontal bar, a jacking mechanism arranged at the end part of the horizontal bar mechanism, a base fixedly connected to the inner wall of the second section, a driving rod connected with the first section and axially extending into the base from the end part, and a locking unit, wherein the horizontal bar comprises a first section in the middle and second sections respectively arranged at the two ends; the tight mechanism in top is including the mounting panel that can link to each other with the external world, the locking piece that links to each other with the mounting panel, and the slider that only changes continuously with the second section body of whippletree mechanism, be equipped with globular arch on the slider, form the draw-in groove that supplies the globular arch to stretch into on the locking piece, the lateral wall of this draw-in groove is spherical, and when the whippletree moved to arbitrary direction under the exogenic action, the globular arch can be to the spherical lateral wall of draw-in groove slide to do not deviate from the draw-in groove, the locking piece is kept away from to the slider.

The spherical bulge is matched with the clamping groove with the spherical side wall, so that the spherical bulge cannot slip off the clamping groove when the cross bar moves in any direction, the safety performance is high, and the assembly structure is simple, stable and effective; the length of the first section body which is overlapped with the second section body is adjusted by rotating the first section body, so that the length of the cross bar can be adjusted, and the adjusting operation is convenient and effective.

Furthermore, the opening part of draw-in groove extends along the central axis direction of whippletree and forms the cylindricality extension section, form the pillar of being connected with the whippletree cooperation of whippletree on the slider, the tip of pillar is located to spherical arch. The setting of extension section has realized that globular arch can not the dual fail-safe of slippage draw-in groove, and the security performance is higher.

Further, the axial length of the cylindrical extension section is 1/5-1/3 of the depth of the spherical side wall of the clamping groove. The length design of the cylindrical extension section is convenient for assembly, and the spherical protrusion can be ensured not to be separated from the clamping groove.

Furthermore, the periphery of the clamping groove is provided with a plurality of limiting holes, and the periphery of the spherical bulge forms a connecting column which can be inserted into the limiting holes. The assembly between the sliding part and the locking part is simple and stable.

Furthermore, a connecting piece is arranged between the mounting plate and the locking piece, a plurality of mounting seats are arranged on the connecting piece, and the connecting column penetrates through the limiting hole and then extends into the mounting seats. The mounting seat, the locking piece and the sliding piece are all stably mounted, and the whole structure is firmer.

Furthermore, the outer wall of the sliding part is frustum-shaped, and the section of one side of the sliding part, which is close to the cross bar, is smaller than that of the other side of the sliding part.

Furthermore, the outer wall of the locking piece is frustum-shaped, and the section of one side of the locking piece, which is close to the cross bar, is smaller than that of the other side of the locking piece. The frustum-shaped structural design of the sliding part and the locking part enables the pressure born by the cross bar to be dispersed in all directions, the service life of the jacking mechanism is prolonged, the stability is higher, and the use safety performance is also improved.

Furthermore, a plurality of staggered reinforcing ribs are formed on the back surface of the locking piece. The staggered rib design increases the robustness of the locking member.

Furthermore, the locking unit comprises a first locking piece connected to the end part of the first section body in a rotation-stopping matching mode and a second locking piece sleeved outside the second section body, and when the first locking piece and the second locking piece are meshed, the first section body and the second section body are prevented from rotating relatively. The arrangement of the locking unit prevents the first section body and the second section body from loosening randomly after adjustment.

Furthermore, the mounting plate is provided with anti-skid convex ribs. Increasing the friction between the mounting plate and the wall.

When the whippletree removed to arbitrary direction, the spherical protruding top was followed the spherical lateral wall center of draw-in groove and is slided to the edge, because spherical lateral wall concave surface center depth is deepest, all can make the locking piece keep away from the slider to the edge movement of arbitrary direction to promote the tight wall in mounting panel top, that is to say that the whippletree lateral shifting of arbitrary direction all can convert the locking piece along the fore-and-aft driving force of whippletree, and the displacement is big more the top tight more, the realization is connected with the firm of wall. On the other hand, as the spherical bulge is contacted with the spherical side wall depression, the contact surface is very small, the friction force of relative sliding is reduced, the relative sliding is easier to realize, the jacking can be realized under the condition of small applied external force, and the use safety can be ensured no matter adults or children.

The invention has the beneficial effects that: utilize globular protruding and have the draw-in groove cooperation of spherical lateral wall, when the whippletree removed to arbitrary direction, the globular protruding removal of propping the draw-in groove inner wall all the time, and can not the slippage draw-in groove, but the interval between slider and the locking piece changes, and slight bending can take place for slider and whippletree promptly, strong adaptability, the security performance is high, and assembly structure is simple, firm effective.
