Abstract
The utility model relates to an operating rod capable of being bent and folded, which mainly aims to solve the technical problem that an existing operating rod can not be too long or occupies too long time in assembling and the like. The operating rod comprises a sleeve and a driving rod, wherein the driving rod can move back and forth in the sleeve, the sleeve and the driving rod are both composed of two or more sections, two adjacent sections of the driving rod are connected through a bendable structure, and two adjacent sections of the sleeve are in threaded connection through an external connecting pipe. The operating rod adopts a mode of the multi-section structure, thereby being convenient to store and carry and capable of being put in use quickly.
Description
Technical field
The utility model relates to a kind of operation lever structure fulfiling assignment that operates by inner driving stem.
Background technology
Existing control lever adopts the structure of the driving stem that assembling in sleeve pipe can forward and backward movement conventionally.During use, the propelling of the operating grip being connected with driving stem by cannula end or retreat to order about driving stem and move, and then make topworks's work of being connected with driving stem front end.The version of its sleeve pipe has following two kinds: single rod shaped structure and dismounting, modular construction.There is following defect in this class formation: 1, for shaft-like formula structure, the length of its sleeve pipe was subject to the restriction of depositing or carrying, can not be long, thus limit operating personnel and carried out the distance between object, when dangerous operation or uniform suspect, to operating personnel, bring danger.2, for detachable, modular construction, although its sleeve pipe can according to circumstances lengthen; But when assembling, need one to save assembling driving stem and sleeve pipe, holding time is more, thereby delays the time, and the consequence causing is more serious.
Summary of the invention
The utility model be mainly solve in prior art that control lever is existing cannot be long or the technical matters such as holding time is long during assembling, and then provide a kind of can folding storage, easy to carry, the flexible folding control lever that can carry out fast operation task.
Flexible folding control lever of the present utility model includes sleeve pipe and inner driving stem, this driving stem can move forward and backward in sleeve pipe, sleeve pipe and driving stem are by two joints or the above composition of two joints, adjacent two joint driving stems are connected by bent structure, and adjacent two joint sleeve pipes are connected by outer connecting pipe screw thread.
Above-mentioned bent structure is flexible axle.
Above-mentioned bent structure is rigid connecting shaft, the rear and front end of this coupling shaft respectively with the end of prosthomere driving stem and the rotatable front end of deutomerite driving stem be articulated and connected.
The novel flexible folding control lever of this reality adopts multi-section structure form, and collapsible collection between joint and joint, deposits with easy to carry; In use, by outer connecting pipe, tighten sleeve pipe and can use, in the middle of coming into operation fast, save time widely.The utility model can be used for having the various fields of same function, as for the active relevant appliance of speedily carrying out rescue work, can be used for again arresting on related equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is for structure shown in Fig. 1, the structural representation when folded state.
In figure, member label implication is as follows: 100, sleeve pipe, 101, upper joint sleeve pipe, 102, lower joint sleeve pipe, 103, outer connecting pipe; 200, driving stem, 201, upper joint driving stem, 202, lower joint driving stem, 203, bent structure.
Embodiment
Referring to Fig. 1, flexible folding control lever of the present utility model, includes sleeve pipe 100 and inner driving stem 200, and this driving stem 200 can move forward and backward in sleeve pipe 100.General structure is as follows: the front end of driving stem 200 is provided with work members, and rear end is provided with operating grip or actuating unit, by operating grip or actuating unit, orders about control lever in the interior movement of sleeve pipe 100, thereby reaches the object of work members work.Described sleeve pipe 100 and driving stem 200, by two joints or the above composition of two joints, only embody the syndeton between adjacent two joints shown in figure, generally, this sleeve pipe and driving stem can be two joints or three joints.Adjacent two joint driving stems are connected by bent structure 203, and, shown in figure, upper joint driving stem 201 is connected by bent structure 203 with lower joint driving stem 202; Equally, adjacent two joint sleeve pipes are connected by outer connecting pipe 103 screw threads, and shown in figure, upper joint sleeve pipe 101 and lower joint sleeve pipe 102 are threaded by outer connecting pipe 103.The dimension of inner screw thread at described outer connecting pipe two ends should guarantee can with save up and down sleeve pipe and be firmly connected, when pulling down or back out, can move along casing joint wherein again and not affect its folding storage.
Above-mentioned bent structure 203 is rigid connecting shaft (referring to Fig. 1), the rear and front end of this rigid connecting shaft 203 respectively with the end of upper joint driving stem 201 and the rotatable front end of lower joint driving stem 202 be articulated and connected, general rotatable angle should be not less than 90 degree, so that folding storage.Shown in Fig. 1, this rigid connecting shaft 203 by pivot pin with save up and down driving stem and be connected.
As easy structure, above-mentioned bent structure is flexible axle.Its flexible axle length is about 3 times of left and right of its diameter, to guarantee that it can fold smoothly, does not affect again its rigidity.
Referring to Fig. 2, the utility model, when folding storage, is first backed out outer connecting pipe, then that upper and lower two joint driving stems are folding along bent structure, can be easy to carry and collect.
