Abstract

The utility model belongs to the field of sports, and particularly relates to a horizontal bar with a bar strip capable of rotating and fixing, which mainly comprises two support columns (1), a positioning pin (8), the bar strip (9), two bearing blocks (11), two bearings (16) and other parts. The horizontal bar with the bar strip capable of rotating and fixing has the following beneficial effects: firstly, when a handle is pulled downwards and then is clamped at a positioning piece, and the positioning pin is separated from a bar strip hole, a hand holding bar strip can rotate freely along with the swinging of the overhang, palms can not generate friction with the bar strip, so that vesicles can not occur on hands, the palms can not be injured, and further the hand holding bar strip can rotate freely so as to enable the training to more comfortable, and secondly, when the handle rotate outwards, a spring pushes a positioning pin into the bar strip hole, so that the bar strip is fixed, and then is beneficial to complete compulsory exercise by an exerciser. The bar strip is controlled to fix and rotate, so that the purpose that the horizontal bar is used by professional and amateur exercises in a sharing way is achieved.

Description

The horizontal bar that the thick stick bar is rotatable with fixing

Technical field

The utility model belongs to the sports field, the horizontal bar that particularly a kind of thick stick bar is rotatable with fixing.

Background technology

At present, the thick stick bar of the horizontal bar forms that maintain static that adopt more.The thick stick bar of horizontal bar maintains static and helps the practitioner and finish compulsory exercise, but when doing both hands and hold the thick stick hang swing for children and common practitioner, the thick stick bar of horizontal bar maintains static easily hand is ground bubble, the damage palm.

The utility model content

In order to address the above problem, the utility model proposes rotatable with the fixing horizontal bar of a kind of thick stick bar.The technical scheme that the utility model adopted is: the horizontal bar that a kind of thick stick bar is rotatable with fixing, two support columns are fixedlyed connected with ground, fixedly connected with the bearing block that has bearing by upper bracket respectively in the upper end of two support columns in this horizontal bar, thick stick bar in the described horizontal bar is arranged on the inner ring of described bearing, fixedly connected with step with top chock in the outer ring of described bearing, described top chock is connected by bolted with step, and the lower surface of described step is connected by bolted with the upper surface of described upper bracket; Fixedly connected by two circlips for shaft between described thick stick bar and the two bearings.

The described support column outside is welded to connect spacer and lower carriage, and fixed installation has the alignment pin of spring on the described lower carriage, and the two ends of described spring contact with the upper surface of described lower carriage and the lower surface of upper bracket respectively; The end of described thick stick bar is provided with can be for the hole of alignment pin insertion, and the lower end of described alignment pin is provided with handle.

The beneficial effects of the utility model are: one, pulling handle instantly is stuck in spacer, alignment pin is held the thick stick bar and can arbitrarily be rotated with hang swing after breaking away from the thick stick cylindrical void, and palm and thick stick bar do not produce friction, hand can not grind bubble, not damage palm, makes to hold the thick stick bar arbitrarily to rotate exercise more comfortable.Two, when the handle outward turning, spring pushes alignment pin in the thick stick cylindrical void, and the thick stick bar is fixed not change and helps the practitioner and finish compulsory exercise.Fixing and the rotation of above-mentioned lever bar has realized the professional and amateurish shared purpose of practising.

Fig. 5 pulls out the thick stick cylindrical void under Fig. 1 alignment pin, after handle was stuck in spacer, the thick stick bar turned schematic diagram.

The specific embodiment

The utility model is that the thick stick bar at horizontal bar maintains static, and children and common practitioner do when both hands are held the thick stick hang swing and easily hand ground bubble, and the problem of damage palm proposes.The utility model agent technology feature such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4.Concrete structure is by forming with lower member: two support columns 1 serve as conventional fixedlying connected with ground.Spacer 2 inboards are welded to connect with support column 1 outside.Lower carriage 5 inboards are welded to connect with support column 1 outside.Upper bracket 12 lower surfaces and support column 1 upper surface are welded to connect.Alignment pin 8 passes thick stick bar 9, upper bracket 12, spring washer 7, spring 6, lower carriage 5 and handle 3 and is fastenedly connected by screw 4.Top chock 10 is fastenedly connected by bolt 14 with step 11, and step 11 lower surfaces and upper bracket 12 upper surfaces are fastenedly connected by bolt 13, and it is fixedly connected by two circlips for shaft 15 that thick stick bar 9 passes two bearings 16.

When using the thick stick bar to turn with fixing horizontal bar, select the rotation of thick stick bar, the down-drawable handle is stuck in spacer, and after alignment pin broke away from the thick stick cylindrical void, the thick stick bar promptly turned, as shown in Figure 5.Select the fixing of thick stick bar, the handle outward turning, spring pushes alignment pin in the thick stick cylindrical void, and the thick stick bar is fixed and does not change, as shown in Figure 1.

Claims

1. a thick stick bar turns and fixing horizontal bar, two support columns (1) are fixedlyed connected with ground, it is characterized in that: fixedly connected with the bearing block that has bearing (16) by upper bracket (12) respectively in the upper end of two support columns (1) in this horizontal bar, thick stick bar (9) in the described horizontal bar is arranged on the inner ring of described bearing (16), fixedly connected with step (11) with top chock (10) in the outer ring of described bearing (16), described top chock (10) and step (11) are fastenedly connected by bolt (14), and the upper surface of the lower surface of described step (11) and described upper bracket (12) is fastenedly connected by bolt (13); Fixedly connected by two circlips for shaft (15) between described thick stick bar (9) and the two bearings (16).
