Description

Blowing tool

The present invention relates to vehicle warranty tools, and more particularly to a mouthpiece turning tool.

In the technology disclosed in Japanese Patent No. I496708, there is disclosed a mouthpiece kit tool for wearing on a bleeder for facilitating the operation of the mouthpiece, but due to different brands and models. The different nozzles, especially the difference in size, make the single-mouth nozzle kit tool not suitable for the rotation of different size nozzles. Therefore, for the operator, most of the different sizes of the nozzle kit are available. The tool is required for the job.

In the technical content disclosed in the above patent application, the wrench for providing the rotating arm is integrated with the sleeve for socketing on the nozzle, so that the number of the wrench is the same as the number of the sleeve, but The wrench is not as varied as the sleeve depending on the size of the nozzle. Therefore, the number of wrenches with the same number of sleeves is an unnecessary waste, which is not ideal.

Accordingly, it is a primary object of the present invention to provide a mouthpiece rotation tool that reduces the number of pulling elements that provide a rotational force arm to reduce waste.

Therefore, in order to achieve the above object, the mouthpiece rotating tool provided by the present invention comprises a kit for connecting the nozzle and connecting with the external pipeline, and a kit for engaging the kit for the operator. Applying a force member and limiting the position of the trigger member to the sleeve by a fixed side and a side of an elastic side, so that the trigger member can be stably coupled to the sleeve while being compressed by The resilient side removes the elastic side from the limit of the trigger to separate the trigger from the set.

In the technical content, the kit includes a sleeve body and a member of the trigger member. The kit has a tubular body portion, and a mouthpiece end is attached to one end of the body tube shaft. The tube connecting end is disposed at the other end of the tube shaft of the body, a card portion is disposed on the circumference side of the body portion, and a blocking wall is located on one side of the engaging portion to form the fixed side, so that the tube The card portion is interposed between the retaining wall and one end of the body tube shaft.

The trigger member has an annular sleeve portion that is threaded over the body and is selectively engageable with the card portion. An arm extends outwardly from a side of the sleeve portion for a predetermined length.

The utility model is characterized in that the kit further comprises an elastic portion located at a portion between the card portion and the end of the tube shaft of the body portion, and protrudes outside the circumference of the body. a predetermined stopping height for forming the elastic side, and being deformed in a radial direction of the body to reduce the blocking height to a release height, when the elastic portion is located at the height of the stop In the unstressed state, the outer diameter is greater than the minimum inner diameter of the sleeve, and when the elastic portion is in the pressurized state with the release height, the outer diameter is less than or equal to the minimum inner diameter of the sleeve.

Wherein, the elasticity of the elastic portion can be provided by a material or a shape, and can be made into an element such as a rubber ring or a C-ring.

In addition, in order to obtain proper positioning of the elastic portion, the kit further includes an annular recessed groove recessed on the circumferential side surface of the body for the embedding of the elastic portion.

BRIEF DESCRIPTION OF THE DRAWINGS A preferred embodiment of the invention will be described in conjunction with the drawings.

First, referring to the first to third figures, a mouthpiece rotating tool (10) provided in a preferred embodiment of the present invention mainly comprises a kit (20) and a wrench ( 30).

The kit (20) has a sleeve (21) which is a straight tube with two ends permeable, and a connecting tube (22) is coaxially inserted at one end of the tube shaft into one end of the tube shaft of the sleeve (21). The inner space of the sleeve (21) and the connecting tube (22) communicate with each other, and a mouthpiece end (23) of a polygonal wall is attached to the other end of the tube shaft of the sleeve (21). The inner annular surface is engaged with the polygonal column body of the discharge nozzle, and an outer tube connection end (24) is disposed on the other end of the tube shaft of the connection tube (22) for stringing with the external fluid pipeline Connected, a polygonal card portion (25) is disposed on the circumferential side annular surface of the middle portion of the sleeve (21), and is spaced apart from the end of the sleeve (21) by a suitable distance (d1) a radial retaining wall (26) is disposed on the circumferential side of the sleeve (21) and is located on a side of the clamping portion (25) away from the outer tube connecting end (24), and the second ring (27) is Coaxially and spaced apart from each other coaxially protruding on the circumferential side annular surface of the connecting pipe (22), adjacent to one end of the pipe shaft of the casing (21), a fitting groove (28) is interposed therebetween Between the rings (27), a continuous annular rubber elastic portion (29) is nested in the recess (28). And protruding from a predetermined stop height (d2) outside the recessed groove (28), and the card portion (25) is interposed between the elastic portion (29) and the retaining wall (26).

The trigger member (30) has an annular annular sleeve portion (31) having a polygonal inner surface, which is coaxially sleeved on the sleeve (21) and selectively engages with the card portion (25). The height in the axial direction is less than the separation distance, and a plate-shaped arm (32) extends radially outward from one side of the sleeve portion (31) by a suitable length to form a force arm for application of an external force.

Please refer to the third and fourth figures, the elastic portion (29) can reduce the height of the protruding height from the blocking height (d2) to a release when the deformation is under pressure by the elasticity of the material itself. The height (d3) is such that the outer diameter of the elastic portion (29) changes synchronously, and accordingly, when the elastic portion (29) is not pressed, as shown in the third figure, the stop is The outer diameter of the height (d2) is greater than the minimum inner diameter of the sleeve portion (31), and the elastic side is formed on the other side of the sleeve portion (31) so as to be from the side of the sleeve portion (31). The fixed side formed by the wall (26), in common with each other, provides a limit to the sleeve (31) to prevent the trigger (30) from being arbitrarily separated from the sleeve (20), so that the user can use the trigger ( 30) The kit (20) is subjected to a turning operation to perform the operation of turning the mouthpiece.

When the elastic portion (29) is pressed to lower the height of the protrusion to the release height (d3), the outer diameter of the elastic portion (29) is equal to or smaller than the sleeve portion as shown in the fourth figure. The minimum inner diameter of (31) causes the elastic portion (29) to temporarily lose the effect of providing a limit to the sleeve portion (31), so that the sleeve portion (31) can be detached as shown in the fifth figure. The elastic portion (29) is restrained and is separated from the kit (20) from the connecting tube (22).

Wherein, the elastic portion (29) is pressed against the external force, and the disengagement action of the sleeve (20) is not required to be separated from the trigger member (30), in other words, for the operator, The puller (30) is axially outwardly disengaged along the sleeve of the sleeve (20), and pressure is applied to the elastic portion (29) via the inner ring of the sleeve portion (31), thereby forming the elastic portion (29). The pressing force of the pressing causes the elastic portion (29) to be deformed by being pressed, and therefore, it is convenient in use.

Thereby, the trigger (30) is used in combination with a plurality of kits (20) to improve the lack of the prior art, and at the same time, since the elastic portion (29) is still uncompressed, the sleeve can still be used. (31) Providing the restraint effect of the limit is to ensure the convenience of operation in the application of the industry, and to facilitate the operation, avoid waste and be easy to store.
