Abstract
The utility model discloses a bilateral automatic locking device of a pneumatic lifting rod. The bilateral automatic locking device is suitable for being used on lifting rod products with large load, and comprises a lock catch arranged on an inner segment cylinder sleeve of the lifting rod. A first locking groove and a second locking groove are correspondingly arranged on two sides of the lock catch, and a first lock cylinder and a second lock cylinder are arranged to be matched with the first locking groove and the second locking groove. The first lock cylinder and the second lock cylinder are connected with locking elastic components, and plugs are arranged on the outer ends of the locking elastic components. Unlocking components are connected with the first lock cylinder and the second lock cylinder. An automatic locking mechanism is additionally arranged on the bilateral automatic locking device of the pneumatic lifting rod, when uprising needs maintaining for a long period, the automatic locking mechanism anatomically locks the lifting rod. The bilateral automatic locking device is not only simple in structure, low in manufacture cost, but also reliable in control 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 bilateral automatic locking structure 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 bilateral automatic locking structure, 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 bilateral automatic locking structure of a kind of Pneumatic lifting arm, it comprises the snap close that is installed on lifting bar internal segment cylinder sleeve, the both sides correspondence of described snap close offers first and second sealed groove, coordinate first and second sealed groove to be provided with first and second lock core, described first and second lock core all 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 first and second lock core.
Especially, described solution lock assembly comprises first and second release lever plate, and an end of described the first release lever plate is articulated on the first lock core, and the other end connects separates lock handle, one end of described the second release lever plate is articulated on the second lock core, and the other end connects separates lock handle.
Especially, described the first release lever plate connects the first bracing wire, and described the second release lever plate connects the second bracing wire, and described first and second bracing wire is connected on a connecting head jointly, and described connecting head connects one and separates lock handle.
Especially, described locking elastic member is metal coil spring.
Especially, described first and second release lever plate is " L " shape slab construction.
The beneficial effects of the utility model are, the bilateral automatic locking structure of described Pneumatic lifting arm compared with prior art has additional bilateral automatic locking mechanism, when needs keep rising for a long time, automatic locking mechanism is locked lifting bar automatically, be adapted at than using (load below 300 kilograms) on the lifting bar product of heavy load, 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 bilateral automatic locking structure 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 bilateral automatic locking structure of Pneumatic lifting arm that provides of the utility model embodiment 1.
in the present embodiment, the bilateral automatic locking structure of a kind of Pneumatic lifting arm comprises the snap close 1 that is installed on lifting bar internal segment cylinder sleeve, the both sides correspondence of described snap close 1 offers the first sealed groove 2 and the second sealed groove 3, coordinate the first sealed groove 2 and the second sealed groove 3 to be provided with the first lock core 4 and the second lock core 5, the outside of described the first lock core 4 and the second lock core 5 all is connected with locking spring 6, the outer end of described locking spring 6 is provided with plug 7, and the first release lever plate 8 that connects " L " shape on described the first lock core 4, the bending part of described the first release lever plate 8 is articulated on the first lock core 4, the other end connects the first bracing wire 9, connect the second release lever plate 10 of " L " shape on described the second lock core 5, the bending part of described the second release lever plate 10 is articulated on the second lock core 5, the other end connects the second bracing wire 11, described the first bracing wire 9 and the second bracing wire 11 are connected on a connecting head 12 jointly, described connecting head 12 connects one and separates lock handle 13.
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, the first lock core 4 and the second lock core 5 snap in respectively the first sealed groove 2, the second sealed groove 3 under the elastic force effect of locking spring 6, 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 13, described the first bracing wire 9 and the second bracing wire 11 drive the first release lever plates 8 and the second release lever plate 10 all moves around its corresponding articulating point, thereby drive elastic force disengaging the first sealed groove 2, the second sealed groove 3 that the first lock core 4 and the second lock core 5 overcome locking spring 6.
The bilateral automatic locking structure 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.
