Abstract

The invention discloses a bolt-pin type adjustable horizontal bar, and belongs to the field of sports apparatus. The bolt-pin type adjustable horizontal bar is adjustable in height so as to be adapted to bodybuilding of people of different heights. The adjustable horizontal bar is characterized by comprising a transverse rod, upper supporting rods and lower supporting rods, wherein a row of pin holes arrayed in the longitudinal direction are formed in one section at the bottom end of each upper supporting rod, one hole corresponding to each pin hole is formed in a corresponding position close to the upper end of each lower supporting rod, and a bolt pin is inserted in each hole; a locking bolt is arranged on the pipe wall of each lower supporting rod below the corresponding bolt pin, and each bolt and the corresponding bolt pin form an angle of 90 degrees; a pressure spring is arranged in each lower supporting rod below the corresponding upper supporting rod, and a pull rod is arranged on the transverse rod. The bolt-pin type adjustable horizontal bar disclosed by the invention is mainly used as horizontal bars in the sports apparatus.

Description

Bolt pin type is adjustable horizontal bar

Technical field

The invention belongs to sports apparatus field, specifically refer to the adjustable horizontal bar of a kind of bolt pin type.

Background technology

Horizontal bar is a kind of important physical training utensil, extensively arrange in the large primary school that teenager concentrates, in addition along with people are to the attention gradually of body building, the also common distribution in places such as residential blocks, it is generally made up of two poles cross bar, what extensively see is all that height can not regulate, and the height two groups that is set to had connects all-in-one-piece mutually, though this facilitates much will take larger space, place; In actual life, people need a kind of horizontal bar that can just regulate to use to facilitate people's body-building of differing heights.

Summary of the invention

Object of the present invention is the new adjustable horizontal bar of technical scheme bolt pin type providing a kind of horizontal bar, and it can eliminate the deficiency of said apparatus.

Technical scheme of the present invention realizes like this, it comprises cross bar, upper rack posts, lower fulcrum bar, be processed with the multiple pin-and-hole of a row of above-below direction arrangement a section of described upper rack posts bottom, near the upper end of lower fulcrum bar, corresponding position is processed with a hole corresponding with pin-and-hole and is inserted with pin in hole; On the tube wall of the lower fulcrum bar below pin, device has and pin clamping screw at an angle of 90, is equipped with stage clip, cross bar is equipped with a pull bar in the lower fulcrum bar simultaneously below upper rack posts.

The invention has the beneficial effects as follows and horizontal bar height can be allowed adjustable, use with the people's body-building adapting to differing heights.

accompanying drawing illustrates:

Fig. 1 is that the design illustrates the front view (higher state) of horizontal bar.

Fig. 2 is the front view of the horizontal bar being in the state of turning down.

Fig. 3 is the left side view (higher state) of horizontal bar.

Fig. 4 is the view of pull bar.

In each figure, 1 is cross bar, and 2 is pull bar, and 3 is upper rack posts, and 4 is pin, and 5 is clamping screw, and 6 is stage clip, and 7 is lower fulcrum bar, and 8 is pin-and-hole.

detailed description of the invention:

The design is illustrated below in conjunction with accompanying drawing.

As shown in Figure 1, Figure 2, Figure 3 shows, the horizontal bar of the design comprises cross bar 1, upper rack posts 3, lower fulcrum bar 7, upper lower fulcrum bar distributes one thin one thick up and down, stage clip 6 is all equipped with in lower fulcrum bar, the lower end of upper rack posts insert lower fulcrum bar upper end and with the upper-end contact of stage clip, at one section of multiple pin-and-hole 8 of a row being processed with above-below direction and arranging of upper rack posts 3 bottom, the axis of pin-and-hole is preferably left and right directions instead of fore-and-aft direction, as shown in Figure 3 to facilitate the people standing in centre to carry out height adjustment operation; Near the upper end of lower fulcrum bar 7, corresponding position is processed with a hole corresponding with aforesaid pin-and-hole and in hole, plugs pin 4 and connected together by upper and lower arm pin; On the tube wall of the lower fulcrum bar below pin, returning apparatus has clamping screw 5, and at an angle of 90, namely the axial of clamping screw is preferably fore-and-aft direction but not left and right directions for it and the projection in the horizontal plane of aforesaid pin; Cross bar is also equipped with a pull bar, as shown in Figure 4.Like this, the adjustable horizontal bar of bolt pin type of the design is just described, when needs are adjusted to lower state (shown in Fig. 2) by higher state (shown in Fig. 1), can first unscrew clamping screw 5, drop-down pull bar 2 after taking out pin, cross bar together with two upper rack posts together with time move down, until just can be inserted by pin in pin-and-hole again and lock clamping screw again to prevent from occurring because there is gap between upper and lower pole relatively to rock after the height needed, improve the security and stability of whole utensil; Otherwise, contrary operation and adjustable height, the suitable elastic force of stage clip can to upper rack posts appear on the stage and under be pulled up to a power-assisted and supporting role, the height regulating function realizing the design's horizontal bar is played to operating help very easily, the operation without this stage clip then can be very inconvenient; The minimal elastic support force of stage clip to upper rack posts is set to support that upper rack posts is most high state, such what is called regulates height be exactly in fact the operating process of a drop-down force and lift force adjustment operation on artificial, and a people just can easily use by complete operation; By a storing of cross bar when pull bar 2 is flat, need to move drop-down use to centre again during adjustment operation.

Claims

1. the adjustable horizontal bar of bolt pin type, it comprises cross bar, upper rack posts, lower fulcrum bar, it is characterized in that one section in the described upper rack posts bottom multiple pin-and-hole of a row being processed with above-below direction arrangement, near the upper end of lower fulcrum bar, corresponding position is processed with a hole corresponding with pin-and-hole and is inserted with pin in hole; On the tube wall of the lower fulcrum bar below pin, device has and pin clamping screw at an angle of 90, is equipped with stage clip, cross bar is equipped with a pull bar in the lower fulcrum bar simultaneously below upper rack posts.
