Abstract
The utility model discloses a unilateral automatic locking device of a pneumatic lifting rod. The unilateral automatic locking device is suitable for being used on lifting rod products with common load, and comprises a lock catch arranged on an inner segment cylinder sleeve of the lifting rod. A locking groove is correspondingly arranged on one side of the lock catch, and a lock cylinder is arranged to be matched with the locking groove. The lock cylinder is connected with a locking elastic component, and a plug is arranged on the outer end of the locking elastic component. An unlocking component is connected with the lock cylinder, and a unilateral automatic locking mechanism is additionally arranged on the unilateral automatic locking device of the pneumatic lifting rod. When uprising needs maintaining for a long period, the automatic locking mechanism automatically locks the lifting rod, and simultaneously once pressure leakage occurs in the lifting rod, due to the action of the locking structure, the lifting rod can not descent under the action of loading gravity. The unilateral automatic locking device of the pneumatic lifting rod is not only simple in structure, low in manufacture cost, but also reliable in controlling action, and enables operation cost of a user system to be greatly reduced.
Description
Technical field
The utility model relates to a kind of Pneumatic lifting arm, especially relates to the monolateral forced locking device of a kind of 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 and can inflate the device of pressing by automatic makeup on control system; Do not reduce with the air pressure that keeps lifting bar inside; Such scheme is also 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.
The model utility content
The purpose of this utility model is to provide a kind of Pneumatic lifting arm monolateral forced locking device, and it has simple in structure; Control action is reliable; Low cost of manufacture; Can effectively solve the problem that exists when in prior art, lifting bar keeps height and position for a long time.
The purpose of this utility model is to be achieved through the following technical solutions:
The monolateral forced locking device of a kind of 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, coordinate sealed groove to be provided with lock core, described lock core is connected with the locking elastic member, the outer end of described locking elastic member is provided with plug, and is connected with the solution lock assembly on described lock core.
Especially, described solution lock assembly comprises the release lever plate, and an end of described release lever plate is articulated on lock core, and the other end connects by bracing wire separates lock handle.
Especially, described locking elastic member is metal coil spring.
Especially, described release lever plate is " L " shape slab construction.
The beneficial effects of the utility model are, the monolateral forced locking device of described Pneumatic lifting arm compared with prior art has additional monolateral automatic locking mechanism, when needs keep rising for a long time, automatic locking mechanism is locked lifting bar automatically, be adapted at using on the lifting bar product of general load (load below 100 kilograms), in case simultaneously lifting bar inside has air pressure to leak, because the effect lifting bar of locking mechanism can not descend under the load action of gravitation.Simple in structure, low cost of manufacture not only; And control action is reliable; Make the operating cost of custom system greatly reduce.
Description of drawings
Fig. 1 is the structural representation of the monolateral forced locking device of Pneumatic lifting arm that provides of the utility model embodiment 1.
Embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
See also shown in Figure 1ly, Fig. 1 is the structural representation of the monolateral forced locking device of Pneumatic lifting arm that provides of the utility model embodiment 1.
In the present embodiment, the monolateral forced locking device of a kind of Pneumatic lifting arm comprises the snap close 1 that is installed on lifting bar internal segment cylinder sleeve one side, offer sealed groove 2 on described snap close 1, coordinate sealed groove 2 to be provided with lock core 3, the outside of described lock core 3 is connected with locking spring 4, the outer end of described locking spring 4 is provided with plug 5, and the release lever plate 6 that connects " L " shape on described lock core 3, the bending part of described release lever plate 6 is articulated on lock core 3, the other end connecting stay wire 7, described bracing wire 7 connects one and separates lock handle 8.
During Pneumatic lifting arm work, the internal segment cylinder sleeve of lifting bar drives snap close 1 along arrow direction in figure, when moving to certain position, lock core 3 snaps in sealed groove 2 under the elastic force effect of locking spring 4, make lifting bar be in locking state, keep for a long time rising to meet the needs of needs, in case and lifting bar inside the air pressure leakage is arranged, because the effect lifting bar of locking mechanism can not descend under the load action of gravitation.
When needing release, pull and separate lock handle 8, described bracing wire 7 drives release lever plate 6 and moves around its corresponding articulating point, thereby overcomes with movable lock core 3 in the sealed groove 2 of elastic force disengaging of locking spring 4, completes release.
The monolateral forced locking device of above-mentioned Pneumatic lifting arm is not only simple in structure, low cost of manufacture; And control action is reliable; Make the operating cost of custom system greatly reduce.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-mentioned example; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
