Abstract

The utility model provides a joint screwing structure which mainly comprises a first joint and a second joint, wherein two rubber rings are combined with each of the first and the second joints; each of two corresponding sides of the first joint and the second joint is extended with a corresponding buckling arm; one side of the buckling arm is extended with a sliding plate; the sliding plates of the first and the second joints are respectively slid into the buckling arms; the buckling arms are mutually clamped with the sliding plates; a safe latch is used for tightly combining the sliding plates of the first and the second joints so as to cause the sliding plates to be firmly combined into integration. The arrangement of the rubber rings causes the connecting point to be tighter so as to achieve the anti-seeping goal.

Description

Joint screws structure

Technical field

The utility model is to screw structure about a kind of joint, is meant a kind of rotation engaging Placement that sees through especially, rapidly two conversion adapter jointings is screwed structure.

Background technique

The application of known body is very extensive, and for example conveying of gas such as water, oil, gas, steam, liquid all needs to reach the purpose that is delivered to far-end by body; Yet the limited length of known body as the fire-fighting body, in case need the conveying of longer distance, will cause the disappearance of fire hose reel curtailment.Therefore, if a conversion adapter can be set between two fire hose reels, the length with the lengthening fire hose reel is only the design of the task of top priority.

This shows that above-mentioned known article still have many disappearances, be not a well design really, and demand urgently being improved.

This case model utility people is urgently to think to be improved innovation in view of every shortcoming of above-mentioned known body, and after concentrating on studies through taking great pains to attain one's goal for many years, successfully research and development are finished the utility model joint and screwed structure finally.

The model utility content

The purpose of this utility model promptly is to provide a kind of button arm engaging mode that sees through, and two conversion adapters are combined closely, and screws structure to reach the joint that extends the body purpose.

A time purpose of the present utility model be to provide a kind of have simple in structure, assembling easily, the joint of many effects such as operation facility screws structure.

The joint that can reach above-mentioned model utility purpose screws structure, includes first conversion adapter, second conversion adapter and cushion rubber; Wherein, the button arm of a correspondence is set all on this first, second conversion adapter, an end of this button arm is the opening shape, and the other end is a closed shape, and all is extended with a slide plate in the opening end of two button arms; Be that cushion rubber is placed in first and second conversion adapter, and first, second conversion adapter mutually combined, make the slide plate on it slip into and buckle in the arm via buckleing the arm opening, and the retaining of being detained the arm closed end is held, it can't be run through, cause the button arm and the slide plate of first and second conversion adapter to fasten, by safety pin it is combined closely again, it firmly is combined into one, to reach the purpose that is assembled fast; And see through the setting of cushion rubber, make the more driving fit of its joint, to reach the effect of antiseepage.

Embodiment

Seeing also shown in Fig. 1 and Fig. 2 A, the B, is that joint provided by the utility model screws structure, mainly includes:

One first conversion adapter 1, the top internal face of this first conversion adapter 1 is provided with screw thread 11, binding for body, the bottom then is extended with corresponding button arm 12, one end of this button arm 12 is a closed shape, the other end is the opening shape, and this opening end respectively is extended with a slide plate 13 certainly, and this slide plate 13 is provided with a hole 131;

One second conversion adapter 2, the surface of second conversion adapter 2 is a level shape 21, binding for body, and in be equipped with a buckle 22 near the position, top, this buckle 22 keeps a spacing with the position, top, and is extended with corresponding button arm 23 in the top of second conversion adapter 2, one end of this button arm 23 is a closed shape, the other end is the opening shape, and this opening end respectively is extended with a slide plate 24 certainly, and this slide plate 24 is provided with a hole 241;

Two cushion rubbers 3, this cushion rubber 3 are incorporated into respectively in first and

second conversion adapter

1,2;

When desire prolongs body length, this first conversion adapter 1 and second conversion adapter 2 are mutually combined, make the button arm 12 on it, 23 enter first respectively,

second conversion adapter

1,2 outer surface, and it is rotated an angle, make the slide plate 13 on the conversion adapter 1 of winning slip into and buckle in the arm 23 via arm 23 opening ends of buckleing of second conversion adapter 2, and the retaining of being detained arm 23 closed ends is held, and can't run through, and the slide plate 24 of this second conversion adapter 2 can slip into buckleing in the arm 12 of first conversion adapter 1 synchronously, cause first and

second conversion adapter

1,2

slide plate

13,24 holes 131,241 is corresponding mutually, by running through of safety pin 4, cause first,

second conversion adapter

1,2 firmly are combined into one, to reach the purpose that prolongs body, and this places first,

second conversion adapter

1,3 of cushion rubbers in 2 can closely contact, make and win,

second conversion adapter

1,2 joint is quite closely knit, to reach the effect of antiseepage.

Other sees also shown in Figure 3, for the utility model is implemented schematic representation, for making the body 5 that is placed on second conversion adapter 2 be difficult for breaking away from second conversion adapter 2, it can be in conjunction with a retaining member 6 on second conversion adapter 2, this retaining member 6 is fastened on the buckle 22 of second conversion adapter 2, and see through two clamping plate 61 body 5 is closely cladded, make that body 5 can be because of flow intensity be not strong excessively, and separate with second conversion adapter 2.

Joint provided by the utility model screws structure, when comparing mutually with other known technologies, has more following advantage:

1. the utility model is combined closely two conversion adapters, to reach the purpose of extending body by button arm engaging mode.

2. the utlity model has simple in structure, many effects such as assembling is easy, operation facility.

But above-listed detailed description is specifying at an embodiment of the present utility model, only this embodiment is not in order to limit claim of the present utility model, all equivalences that does not break away from the utility model skill spirit are implemented or change, all should be contained in the claim of the present utility model.
