Abstract
The invention discloses a bolt type unilateral locking device for a pneumatic lifting rod. The bolt type unilateral locking device for the pneumatic lifting rod is suitable for being applied to a lifting rod with small load weight and comprises a lock catch installed at an inner-section cylinder sleeve of the lifting rod, a locking groove is correspondingly arranged on one side of the lock catch, a bolt type lock cylinder and lock cylinder sleeve are arranged for being matched with the locking groove, a step surface is arranged on the bolt type lock cylinder, an accommodating cavity matched with the bolt type lock cylinder is arranged in the lock cylinder sleeve, one end of the bolt type lock cylinder penetrates in the accommodating cavity to extend out from the other end of the lock cylinder sleeve, an elastic locking component is arranged between the step surface of the bolt type lock cylinder and the lock cylinder sleeve, and one end of the bolt type lock cylinder extending out of the lock cylinder sleeve is connected with a unlocking component. The bolt type unilateral locking device is simple in structure, low in manufacturing cost and reliable in control action and enables operation cost of a user system to be reduced greatly.
Description
Technical field
The present invention relates to a kind of Pneumatic lifting arm, especially relate to the monolateral locking device of a kind of bolt-type for Pneumatic lifting arm.
Background technique
Pneumatic lifting arm has the advantages such as load is large, noise is little, lifting is fast, shock resistance is little, the shock-absorbing capacity that certainly falls is strong, steady, at golf, the place night illumination such as soccer stadium and various natural disaster, accident play an important role in speedily carrying out rescue work, rescue on-the-spot night.
At present, the Pneumatic lifting arm major part does not have locking device; So be not suitable with the occasion that rises keeping for a long time; If Pneumatic lifting arm need to keep height for a long time; Frequent adopted solution is; Increase by a cover in control system and can inflate the device of pressing by automatic makeup; Do not reduce with the air pressure that keeps lifting bar inside; Such scheme also is effectively feasible really; But need to increase higher cost; And uneconomical; In case lifting bar inside has air pressure to leak, lifting bar can descend under the load action of gravitation, and safety reliability is low.
Summary of the invention
The object of the present invention is to provide the monolateral locking device of a kind of bolt-type for Pneumatic lifting arm, it has simple in structure; Control action is reliable; Low cost of manufacture; Can effectively solve the problem that exists when lifting bar keeps height and position for a long time in the prior art.
The objective of the invention is to be achieved through the following technical solutions:
The monolateral locking device of a kind of bolt-type for Pneumatic lifting arm, it comprises the snap close that is installed on lifting bar internal segment cylinder sleeve, one side correspondence of described snap close offers sealed groove, cooperate sealed groove to be provided with bolt-type lock core and lock core cover, on the described bolt-type lock core step surface is set, offer the holding cavity that cooperates the bolt-type lock core in the described lock core cover, one end of described bolt-type lock core penetrates holding cavity and stretches out from the other end that lock core overlaps, and be provided with the locking elastic member between the step surface of described bolt-type lock core and the lock core cover, an end that stretches out the lock core cover of described bolt-type lock core connects separates lock assembly.
Especially, described solution lock assembly comprises the attachment hole on the end that stretches out the lock core cover that is opened in the bolt-type lock core, connects the release draw ring in the described attachment hole.
Especially, described locking elastic member is metal coil spring.
Beneficial effect of the present invention is, the monolateral locking device of described bolt-type for Pneumatic lifting arm compared with prior art has additional the monolateral locking device of bolt-type, when needs keep rising for a long time, locking device is locked lifting bar automatically, be adapted at using on the lifting bar product of less load weight (load below 30 kilograms), in case lifting bar inside has air pressure to leak simultaneously, because the effect lifting bar of locking device can not descend under the load action of gravitation.Simple in structure, low cost of manufacture not only; And control action is reliable; So that the operating cost of custom system reduces greatly.
Description of drawings
Fig. 1 is the structural representation of the monolateral locking device of bolt-type that is used for Pneumatic lifting arm that provides of the specific embodiment of the invention 1.
Embodiment
Further specify technological scheme of the present invention below in conjunction with accompanying drawing and by embodiment.
See also shown in Figure 1ly, Fig. 1 is the structural representation of the monolateral locking device of bolt-type that is used for Pneumatic lifting arm that provides of the specific embodiment of the invention 1.
In the present embodiment, the monolateral locking device of a kind of bolt-type for Pneumatic lifting arm comprises the snap close 1 that is installed on lifting bar internal segment cylinder sleeve, one side correspondence of described snap close 1 offers sealed groove 2, cooperate sealed groove 2 to be provided with bolt-type lock core 3 and lock core cover 4, one step surface 5 is set on the described bolt-type lock core 3, offer the holding cavity 6 that cooperates bolt-type lock core 3 in the described lock core cover 4, one end of described bolt-type lock core 3 penetrates holding cavity 6 and stretches out from the other end of lock core cover 4, and be provided with locking spring 7 between the step surface 5 of described bolt-type lock core 3 and the lock core cover 4, an end that stretches out lock core cover 4 on the described bolt-type lock core 3 offers attachment hole 8, described attachment hole 8 interior connection release draw rings 9.
During Pneumatic lifting arm work, the internal segment cylinder sleeve of lifting bar drives snap close 1 along arrow direction among the figure, when moving to certain position, bolt-type lock core 3 snaps in the sealed groove 2 under the elastic force effect of locking spring 7, make lifting bar be in locking state, keep for a long time rising needs to meet the needs of, in case and lifting bar inside have air pressure to leak, owing to the effect lifting bar of locking mechanism can not descend under the load action of gravitation.
When needing release, thereby the elastic force that pulling release draw ring 9 drive bolt-type lock cores 3 overcome locking spring 7 breaks away from the sealed groove 2, finishes release.
The monolateral locking device of above-mentioned bolt-type for Pneumatic lifting arm is not only simple in structure, low cost of manufacture; And control action is reliable; So that the operating cost of custom system reduces greatly.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
