Abstract

The invention provides a balk board assembly, which comprises a vertical balk board, a fixed board and at least one elastic connecting band, wherein the fixed board is arranged on the lower side of the balk board; the upper end surface of the horizontal fixed board is connected with the lower end surface of the balk board by a hinge; two ends of each elastic connecting band are respectively fixedly arranged on the upper end of the balk board and the fixed board. Because the fixed board is fixedly arranged on the bottom surface, when the balk board is under the action of external force, the balk board rotates by taking the axis of rotation of the hinge as an axle to prevent the balk board from being subjected to hard contact with a force application object, the damage of the force application object due to the collision of the balk board is reduced, and then, the balk board is restored to the state before being stressed under the action of the elastic connecting band. The balk board assembly disclosed by the invention has the beneficial technical effect that the structure is simple, the damage of the balk board and the force application object after collision is reduced, and the balk board assembly can be automatically restored to the use state before collision.

Description

Balk board assembly

Technical field

The present invention relates to a kind of balk board assembly.

Background technology

Leaping over obstacles plate training program is generally used in outdoor military training and teaching, leaping over obstacles plate training program is used fixed balk board assembly conventionally, at present, balk board assembly comprises that a balk board wooden or cement structures is rigidly fixed on bottom surface, but because balk board can not deformation, personnel once cross over failure or botching routines, easily cause the injury gained in sports at the positions such as leap person's shank in crossing over training.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of balk board assembly simple in structure, and when this balk board assembly can be subject to external force, balk board reverses.

For solving the problems of the technologies described above, the invention provides a kind of balk board assembly, comprise the balk board of vertical placement, the fixed head that is arranged on balk board downside and at least one elastic connecting strip, between the fixed head upper surface of level and balk board lower surface, by gemel connection, the two ends of each elastic connecting strip are separately fixed on balk board upper end and fixed head.

Adopt after such structure, fixed head fixes on the ground, while not being subject to External Force Acting, balk board is and vertically stands in fixed head upside under elastic connecting strip effect, when balk board is being subject to the External Force Acting used time, it is axle rotation that balk board can be take the rotation of hinge, prevents that balk board from contacting firmly with application of force object, reduce the damage that application of force object produces because of balk board collision, balk board recovers the state before stressed under the effect of elastic connecting strip afterwards.

Useful technique effect of the present invention is: damage simple in structure, to reduce the rear balk board of collision and application of force object, the state before automatic recovery collision.

Technology contents for a better understanding of the present invention, below by this balk board assembly referred to as this assembly.

There is the inclusion enclave of parcel balk board in the balk board outside of this assembly, and the material of inclusion enclave is rubber, plastics or sponge; Adopt after such structure, further reduce the damage that application of force object produces because of collision.

On the fixed head of this assembly, there is loss of weight notch; Adopt after such structure, reduce the shared volume of fixed head, reduce costs.

Fig. 1 is the front view of this assembly embodiment.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the enlarged drawing of the A part of Fig. 2.

Fig. 4 is the top view of Fig. 1.

The specific embodiment

As shown in Figures 1 to 4

This assembly comprises the fixed head 1, balk board 2 of horizontal positioned, two elastic connecting strips 4 and two hinges 3.

On the front end face length direction of fixed head 1, have loss of weight notch 12, and loss of weight notch 12 runs through the upper and lower end face of fixed head 1.

Wooden balk board 2 is roughly cuboid, and balk board 2 is placed on fixed head 1 upside, and balk board 2 outsides are enclosed with sponge 21.

Between balk board 2 and fixed head 1, by two hinges 3, be connected, each hinge 3 comprises blade 31, lower blade 32 and rotating shaft 33, blade 31 is bolted on the lower surface of balk board 2, lower blade 32 is bolted on fixed head 1 rear portion, upper surface, the axial direction of the rotating shaft 33 of hinge 3 is consistent with the length direction of balk board 2 lower surfaces, the rotating shaft 33 of hinge 3 is arranged on relative lower blade 32 away from fixed head 1 front end face position, and the axis of the rotating shaft 33 of two hinges 3 is on same straight line.

Between balk board 2 and fixed head 1, be also connected with two elastic connecting strips 4, the two ends of each elastic connecting strip 4 are fixed by screws in respectively on the front end face of fixed head 1 and on the front end face of balk board 2.

As shown in Figure 5

During use, the fixed head 1 of this assembly is horizontally fixed on bottom surface, in obstacle training, leap person crosses over this assembly along fixed head 1 front end to balk board 2 directions, once leap person crosses over failure or botches routines, leap person's health contacts with balk board 2, balk board 2 can be axle rotation along the rotating shaft 33 of hinge 3, prevent that balk board 2 from contacting firmly with leap person, the damage of avoiding leap person to produce because of balk board 2 collision, balk board 2 recovers the state before stressed under the effect of elastic connecting strip 4 afterwards.

Above-mentioned elastic connecting strip 4 is elastic threads.

Above-described is only one embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, and these also should be considered as belonging to protection scope of the present invention.

Claims
