Abstract

The utility model discloses a kind of jumping stand.This jumping stand, including two mark posts being vertically arranged, a horizontally disposed cross bar it is provided with between two mark posts, the two ends of described cross bar are connected with the mark post slip of both sides by a bindiny mechanism respectively, described bindiny mechanism includes outer sleeve and the inner sleeve being set-located, described inner sleeve is sheathed on mark post, the clamp sleeve that an inner surface is the conical surface it is provided with between outer sleeve and inner sleeve, the outer surface of described clamp sleeve is threadeded with the inner surface of outer sleeve, the sidewall of inner sleeve offers several grooves arranged along inner sleeve length direction, the compact heap that an outer surface fits tightly it is embedded with clamp sleeve inner surface in groove.The two ends of cross bar can be firmly fixed on mark post by this jumping stand, it is to avoid athlete touches cross bar during crossing bar, is touched off by cross bar from jumping stand, occur that cross bar drops the athletic situation of contusion that fractures, and use easy to adjust.

Description

A kind of jumping stand

Technical field

This utility model relates to a kind of jumping stand.

Background technology

High jump is one of track and field sports jump event, including run-up, takeoff from one foot, the bar that soared, the action such as land, high jump The equipment that motion uses is jumping stand, the high computational achievement of upper limb of the most successfully crossing the bar with athlete during training according to this Judge ranking, training at ordinary times to be heightened along with training requirement the cross bar on jumping stand.Existing jumping stand is typically The mark post on jumping stand both sides is provided with fixation clamp, is then ridden on fixation clamp at the two ends of cross bar.Need to regulate the height of cross bar Time, first the fixation clamp of both sides is unclamped the scale moving either up or down to specify, then fixation clamp is clipped on mark post, then will Cross bar rides on fixation clamp.This structure is easy to touch cross bar, by cross bar from jumping stand during athlete crosses bar Touch off, occur that cross bar drops to fracture and dampen athletic situation.Additionally, traditional jumping stand height is typically directly indicated in mark post Surface on, fixation clamp can wear and tear graduation mark in moving process frequently, affects people and uses.

Utility model content

This utility model is in order to make up the deficiencies in the prior art, it is provided that one is reasonable in design, easy to adjust, cross bar can The stable jumping stand being erected between mark post, solves problems of the prior art.

This utility model is achieved by the following technical solution:

A kind of jumping stand, including two mark posts being vertically arranged, the bottom of described mark post is fixed on two support seats, two Being provided with a horizontally disposed cross bar between mark post, is slided by the mark post of a bindiny mechanism with both sides respectively in the two ends of described cross bar Being connected, be respectively equipped with a rule in the side of every mark post, described bindiny mechanism includes the outer sleeve that is set-located and interior Sleeve, described inner sleeve is sheathed on mark post, is provided with the clamp sleeve that an inner surface is the conical surface between outer sleeve and inner sleeve, The outer surface of described clamp sleeve is threadeded with the inner surface of outer sleeve, offers several along interior on the sidewall of inner sleeve The groove that length sleeve direction is arranged, is embedded with the compression that an outer surface fits tightly with clamp sleeve inner surface in groove Block, is installed with a rotary handle at the top of clamp sleeve.

The material of described compact heap is elastomeric material.

The beneficial effects of the utility model are: this jumping stand, can be firmly fixed on mark post at the two ends of cross bar, it is to avoid Athlete touches cross bar during crossing bar, is touched off by cross bar from jumping stand, occurs that cross bar drops the contusion athlete that fractures Situation, and use easy to adjust, when needing the height regulating cross bar, first rotate the rotation at clamp sleeve top on two mark posts Handle, clamp sleeve, during rotation moves up, gradually unclamps the extruding to compact heap, thus compact heap and mark post table The active force in face is also removed, and can move up and down cross bar to the height needed.Then, opposite direction rotates clamping sleeve on two mark posts The rotary handle at cylinder top, clamp sleeve is during rotation moves down, and its inclined-plane can constantly extrude the appearance of compact heap Face, makes compact heap to inner sleeve medial movement, is closely attached to mark post surface, can be once again secured on mark post by cross bar.Additionally, This jumping stand is provided with rule rather than is set directly on scale by graduation mark in the side of mark post, it is to avoid graduation mark quilt Abrasion.

Detailed description of the invention

For the technical characterstic of this programme can be clearly described, below by detailed description of the invention, and combine its accompanying drawing, to this reality It is described in detail with novel.

As shown in figs. 1-3, this embodiment includes that two mark posts being vertically arranged 1, the bottom of described mark post 1 are fixed on Two support on seat 2, are provided with a horizontally disposed cross bar 3 between two mark posts 1, and the two ends of described cross bar 3 are respectively by a connection Mechanism slides with the mark post 1 of both sides and is connected, and is respectively equipped with a rule 4 in the side of every mark post 1, and described bindiny mechanism includes The outer sleeve 5 being set-located and inner sleeve 6, described inner sleeve 6 is sheathed on mark post 1, between outer sleeve 5 and inner sleeve 6 Being provided with the clamp sleeve 7 that an inner surface is the conical surface, the outer surface of described clamp sleeve 7 is threadeded with the inner surface of outer sleeve 5, The sidewall of inner sleeve 6 offers several grooves 8 arranged along inner sleeve length direction, is embedded with outside one in groove 8 The compact heap 9 that surface fits tightly with clamp sleeve 7 inner surface, is installed with a rotary handle 10 at the top of clamp sleeve 7.

The material of described compact heap 9 is elastomeric material.

When needing the height regulating cross bar 3, first rotate the rotary handle 10 at clamp sleeve 7 top, clamping sleeve on two mark posts 1 Cylinder 7 during rotation moves up, gradually unclamps the extruding to compact heap 9, thus the work on compact heap 9 and mark post 1 surface Firmly also removed, cross bar 3 can be moved up and down to the height needed.Then, opposite direction rotates clamp sleeve 7 on two mark posts 1 The rotary handle 10 at top, clamp sleeve 7 is during rotation moves down, and its inclined-plane can constantly extrude outside compact heap 9 Surface, makes compact heap 9 to inner sleeve 6 medial movement, is closely attached to mark post 1 surface, cross bar 3 can be once again secured in mark post 1 On.

This utility model does not describes part in detail, is the known technology of those skilled in the art of the present technique.Finally illustrate, with Upper embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although with reference to preferred embodiment to this utility model It is described in detail, it will be understood by those within the art that, the technical solution of the utility model can have been repaiied Changing or equivalent, without deviating from objective and the scope of technical solutions of the utility model, it all should be contained at this utility model Right in the middle of.
