The utility model is further arranged to: not there is the draw-bar seat side for extending vertically upwards baffle to have slope Face.

The utility model is further arranged to: offering slot tag on the slope.

The utility model is further arranged to: the bottom of the clamping rear end has mandril embedded hole.

In conclusion the utility model has the following beneficial effects: self ejection type chest pull rod involved in the utility model, By pull rod tip designs at open end and by lid is closed, convenient for opening and carrying out the installation and maintenance in internal portion, also Help dismount；Intermediate plate is set by pressing on sliding block, reset spring is set on intermediate plate, is operated for realizing the reset after sliding block pressing, The convex setting in side, anti-limited slip block are dropped out out of through-hole, play the role of limit；Clamping rear end on intermediate plate helps clamping When front end is lifted, so that clamping backend synchronization moves downward, the consistency for keeping drawbar height to adjust realizes that drawbar height is adjusted Smooth, allomeric function is perfect, practical.

Specific embodiment

The present invention will be further described with preferred embodiment with reference to the accompanying drawing.

Referring to shown in Fig. 1 to 3, a kind of self ejection type chest pull rod involved in the present embodiment, including three sides have and hang down The draw-bar seat 1 of baffle is directly upwardly extended, the pull rod of U-shaped shape is slidably connected on draw-bar seat 12, the pull rod is shell knot 2 Bottom is had through-hole 32 by structure, pull rod, and sliding block 4 moving up and down is embedded in through-hole 3, has limitation on sliding block 4 side The side convex 5 that sliding block 4 is dropped out out of described through-hole 3, the setting of side convex 5, anti-limited slip block 4 are dropped out out of through-hole 3, play the work of limit With；The pull rod is open end top 2, is covered with a lid 6, thereon convenient for opening and carrying out the installation and dimension in internal portion Shield, additionally aids dismounting；The left and right sides inside 2 is equipped with two groups of otic placode groups 7 extended vertically upwards, every group of ear by the pull rod Board group 7 includes two front and back auricles 71 disposed in parallel, is rotatably connected to and is arranged between two auricle 71 in every group of otic placode group 7 Intermediate plate 8, intermediate plate 8 have clamping front end 81 and clamping rear end 82, and clamping front end 81 is pressed on 4 upper surface of sliding block, the folder It holds to be sticked on front end 81 and has reset spring 9,9 both ends of reset spring are affixed 2 front and back inner surface with the pull rod respectively.

In the present embodiment, by applying a upward power to 4 lower surface of sliding block, sliding block 4 is moved upwards, intermediate plate 8 It clamps front end 81 to be lifted upwards, reset spring 9 deforms, and clamping rear end 82, which synchronizes, to be moved downward, and after the completion of force, clamps front end 81 On reset spring 9 restore deformation, to clamping front end 81 generate a downward power, clamping front end 81 move downward, sliding block 4 is simultaneously It moves downward, clamping rear end 82 is lifted and restores to initial position upwards, and sliding block 4 is also restored to initial position.

Further, the draw-bar seat 1 does not have slope 10 with the side for extending vertically upwards baffle, convenient for holding Portion is put into pull rod 2 lower sections, helps to lift pull rod 2.

Further, slot tag 11 is offered on the slope 10, for being sticked, placing label.

Further, the bottom of the clamping rear end 82 has mandril embedded hole 12, for installation and adjustment drawbar height Mandril.

The utility model passes through pull rod tip designs at open end and by lid is closed, convenient for opening and carrying out internal portion Installation and maintenance, additionally aid dismounting；Intermediate plate is set by pressing on sliding block, reset spring is set on intermediate plate, for realizing sliding block Reset operation after pressing, the convex setting in side, anti-limited slip block are dropped out out of through-hole, play the role of limit；Clamping on intermediate plate Rear end facilitates when clamping front end lifting, so that clamping backend synchronization moves downward, keeps drawbar height to adjust consistent Property, it is smooth to realize that drawbar height is adjusted, allomeric function is perfect, practical.

The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain Available technical solution is tested, it all should be within the scope of protection determined by the claims.
