Description

Signal worm wheel with hand wheel quickly detached

Technical Field

The utility model relates to a signal worm wheel that hand wheel was swiftly dismantled belongs to signal worm wheel field.

Background

The signal worm wheel is also called a signal worm wheel box and is assembled on a valve to play a role in controlling the positioning of a valve switch, the existing signal worm wheel is connected with a hand wheel which controls the opening and closing of the existing signal worm wheel in a bolt fixing mode, and the hand wheel needs to be disassembled by using tools in the batch carrying process, so that the operation is inconvenient.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims at providing a signal worm wheel that hand wheel was swiftly dismantled to what solve current signal worm wheel and the hand wheel that control on and off on it adopted is that the mode of bolt fastening is connected, in handling in batches, needs use tool to dismantle the hand wheel, comparatively inconvenient problem.

In order to achieve the above purpose, the present invention is realized by the following technical solution: the utility model provides a signal worm wheel that swift dismantlement of hand wheel, its structure includes worm wheel box, bull stick, hand wheel, the hand wheel comprises locating piece and rim plate, bull stick one end meets with the worm wheel box, extends to have the stopper in the middle of the other end, the locating piece tip is equipped with the assembly groove, the assembly groove cup joints bull stick and stopper simultaneously, the stopper tip is equipped with the draw-in groove that extends to in the bull stick, be equipped with the assembly positioning structure who joins in marriage the draw-in groove on the assembly groove, assembly positioning structure comprises the kelly of two interval settings, bull stick outer wall both sides all are equipped with one with the communicating slide of kelly bottom, and two kelly tip do not block in corresponding slide inner wall, slide in the slide and be equipped with the depression bar, the one end that the kelly was kept away from to the depression bar is equipped with the briquetting.

Further, the clamping rod is made of elastic materials.

Further, the cross section of the positioning block is of a regular hexagon structure.

The utility model has the advantages that: the hand wheel is provided with a quick and convenient dismounting structure, so that the hand wheel dismounting convenience in the carrying process is effectively improved.

Drawings

Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:

fig. 1 is a schematic structural view of a signal worm wheel with a quickly disassembled hand wheel of the present invention;

fig. 2 is a schematic cross-sectional structure diagram of the hand wheel and the rotating rod.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1 and 2, the present invention provides a signal worm gear with a quickly disassembled hand wheel, which comprises: the structure of the device comprises a worm wheel box body 1, a rotating rod 2 and a hand wheel, wherein the hand wheel consists of a positioning block 3 and a wheel disc 4, one end of the rotating rod 2 is connected with the worm wheel box body 1, a limiting block 5 extends from the middle of the other end of the rotating rod, the end part of the positioning block 3 is provided with an assembly groove 6, the assembly groove 6 is simultaneously sleeved on the rotating rod 2 and the limiting block 5, the end part of the limiting block 5 is provided with a clamping groove 7 extending into the rotating rod 2, the assembly groove 6 is provided with an assembly positioning structure 8 matched with the clamping groove 7, the assembly positioning structure 8 consists of two clamping rods arranged at intervals, two sides of the outer wall of the rotating rod 2 are respectively provided with a slideway 9 communicated with the bottom of the clamping groove 7, the end parts of the two clamping rods are respectively clamped on the inner walls of the corresponding slideways 9, a pressing rod 10 is arranged in the slideway 9 in a sliding manner, the clamping rod is made of elastic materials, and the cross section of the positioning block 3 is of a regular hexagon structure.

For example, when dismantling the hand wheel, only need press the briquetting 11 of bull stick 2 both sides, briquetting 11 drives depression bar 10 and produces the effort to the kelly tip, reset spring 12 compression produces deformation, the restriction to slide 9 inner wall is relieved to the kelly tip, and in deformation withdrawal draw-in groove 7, the dismouting personnel can extract the hand wheel, assembly positioning structure 8 breaks away from draw-in groove 7, assembly groove 6 breaks away from locating piece 3 and bull stick 2, accomplish dismantlement work, when needs are installed, it can directly with assembly positioning structure 8 insert draw-in groove 7, locating piece 3 and assembly groove 6 assemble the effect that plays the location restriction.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
