Abstract
The invention discloses the monolateral forced locking device of a kind of Pneumatic lifting arm, the lifting bar product being suitable for general load uses.It comprises the snap close being installed on lifting bar internal segment cylinder sleeve, the side correspondence of described snap close offers sealed groove, and coordinate sealed groove to be provided with lock core, described lock core is connected with locking elastic member, the outer end of described locking elastic member is provided with plug, and described lock core is connected with unlocking feature.The monolateral forced locking device of above-mentioned Pneumatic lifting arm has additional monolateral automatic locking mechanism, when needs keep rising for a long time, automatic locking mechanism is locked lifting bar automatically, simultaneously once there is gas pressure leak lifting bar inside, because the effect lifting bar of locking mechanism can not decline under the effect of load gravity.Not only structure is simple, low cost of manufacture; And control action is reliable; The operating cost of custom system is reduced greatly.
Description
Technical field
The present invention relates to a kind of Pneumatic lifting arm, especially relate 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 illuminations such as soccer stadium and various natural disaster, accident are speedily carried out rescue work on-the-spot night, rescue in play an important role.
At present, Pneumatic lifting arm major part does not have locking device; So be not suitable with in the occasion needing to keep for a long time rising; If Pneumatic lifting arm needs to keep height for a long time; Frequent adopted solution is; Control system increases a set of can automatic makeup inflation pressure device; Do not reduce to keep the air pressure of lifting bar inside; Such scheme is also effectively feasible really; But need to increase higher cost; And it is uneconomical; Once there is gas pressure leak lifting bar inside, lifting bar can decline under the effect of load gravity, and safety reliability is low.
Summary of the invention
The object of the present invention is to provide the monolateral forced locking device of a kind of Pneumatic lifting arm, it is simple that it has structure; Control action is reliable; Low cost of manufacture; Effectively can solve Problems existing when lifting bar in prior art keeps height and position for a long time.
The object of the invention 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 being installed on lifting bar internal segment cylinder sleeve, the side correspondence of described snap close offers sealed groove, sealed groove is coordinated to be provided with lock core, described lock core is connected with locking elastic member, the outer end of described locking elastic member is provided with plug, and described lock core is connected with unlocking feature;
Described unlocking feature comprises release lever plate, and one end of described release lever plate is articulated with on lock core, and the other end is connected 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.
Beneficial effect of the present invention is, 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, the lifting bar product being adapted at general load uses (less than 100 kilograms loads), simultaneously once there is gas pressure leak lifting bar inside, because the effect lifting bar of locking mechanism can not decline under the effect of load gravity.Not only structure is simple, low cost of manufacture; And control action is reliable; The operating cost of custom system is reduced greatly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the monolateral forced locking device of Pneumatic lifting arm that the specific embodiment of the invention 1 provides.
Embodiment
Technological scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
Refer to shown in Fig. 1, Fig. 1 is the structural representation of the monolateral forced locking device of Pneumatic lifting arm that the specific embodiment of the invention 1 provides.
In the present embodiment, the monolateral forced locking device of a kind of Pneumatic lifting arm comprises the snap close 1 being installed on lifting bar internal segment cylinder sleeve side, described snap close 1 offers sealed groove 2, sealed groove 2 is coordinated 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 described lock core 3 connects the release lever plate 6 of " L " shape, the bending part of described release lever plate 6 is articulated with on lock core 3, the other end connecting stay wire 7, described bracing wire 7 connects a solution 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, lifting bar is made to be in locking state, keep for a long time rising needs to meet the needs of, and once there is gas pressure leak lifting bar inside, because the effect lifting bar of locking mechanism can not decline under the effect of load gravity.
When needing to unlock, pull and separate lock handle 8, described bracing wire 7 drives release lever plate 6 to move around the articulating point of its correspondence, thus the elastic force that band movable lock core 3 overcomes locking spring 4 departs from sealed groove 2, completes unblock.
The monolateral forced locking device of above-mentioned Pneumatic lifting arm not only structure is simple, low cost of manufacture; And control action is reliable; The operating cost of custom system is reduced greatly.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention does not limit by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and change all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
