Description

A kind of clamping device

Technical field

This utility model is related to the mounting technique field of emergency set, more particularly to a kind of clamping device.

Background technology

Gasbag is widely used in emergency set, and gasbag upper air valve port, actuator epithelium, breathing valve port and housing connect Valve port is connect, generally housing connection valve port is tightened using lid and is fixed on housing, so far, for the installation of lid is tightened All it is to be locked with handss using employee, is difficult operation difficultly, and sometimes some products do not reach locking.

The content of the invention

This utility model provides a kind of clamping device, replace it is artificial lock, simple structure, low cost and locking effect is more It is good, in order to reach object above, employ the following technical solutions：This utility model includes：Handle, chuck and bushing, the lining Set is nested in collet interior, and the interior border of the bushing is distributed with spline.

Preferably, positioning convex is also distributed with the outlet of the bushing.

Preferably, in the chuck, border is provided with stopper slot, and the stopper slot is matched with positioning convex, the chuck Ability of anti-deformation, hardness more than bushing ability of anti-deformation and hardness.

Preferably, the chuck and handle can be integral type structure, also movable connection between the chuck and handle.

Preferably, the bushing and positioning convex can be nylon material.

Preferably, the chuck can be ferrous materials.

The beneficial effects of the utility model：Collet interior is nested with bushing, and ability of anti-deformation and the hardness of chuck are both greater than Bushing, bushing adopt nylon material, in bushing, border is provided with the spline matched with lid, can increase and fit with lid Degree, and prevent the deformation of bushing, rotary handle and chuck from realizing tightening for lid, easy to operate and low cost, handle and chuck Between connected using integral type or it is dismountable be flexibly connected, be convenient for the dismounting and change of individual part, be also convenient for carrying, together When, at least two kinds of the link position relation between handle and chuck, to adapt to different spaces, using the knot of present patent application Structure, easy to operate, simple structure and low cost.

Specific embodiment

Shown in Fig. 1, Fig. 2, Fig. 4, Fig. 5, this utility model includes：Handle 1, chuck 2 and bushing 3, the lining Set 3 is nested in inside chuck 2, and the chuck 2 and handle 1 can be integral type structure, the folder between the chuck 2 and handle 1 Angle can be 180 °, or 90 °, the mainly demand according to space in installation process, space can than in the case of larger Using 180 ° of angles, the handle 1 and chuck 2 of 90 ° of angle can be adopted in the case that space is smaller.

Shown in Fig. 6, Fig. 7, the chuck 2 can also be using being removably flexibly connected, i.e., by spiral shell with handle 1 The devices such as bolt, pin are fixed, the chuck 2 and handle 1 after dismounting in order to carry, while can also be according to space requirement more The size of hand-off handle 1, and individual part occurs only to carry out the repair and replacement for damaging part when damaging without integrally more Change, save cost.

Understand as shown in Figure 3, positioning convex 4, the interior border of the bushing 3 in the outlet of the bushing 3, is also distributed with Spline 5 is distributed with, spline 5 is matched with the structure of cover outer surface, is easy to position lid and is driven lid Circumferential movement, is also provided with certain matsurface inside the spline 5, can arrange particulate matter or anti-slip tank, increase with Frictional force between lid.

Preferably, in the chuck 2, border is provided with stopper slot, and the stopper slot is matched with positioning convex 4, to bushing 3 carry out it is spacing prevent its occur circumferential movement cause lid twist it is not tight.

The bushing 3 and positioning convex 4 can be nylon material, and the ability of anti-deformation of the chuck 2, hardness are more than bushing 3 Ability of anti-deformation and hardness, the chuck 2 can be ferrous materials, prevent in operation, the bushing 3 of nylon material occurs Deformation.

The principle and its effect of above-described embodiment only illustrative present patent application, not for restriction this patent Shen Please.Any person skilled in the art all can be carried out to above-described embodiment under without prejudice to the spirit and the scope of present patent application Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the essence disclosed in present patent application All equivalent modifications completed under god and technological thought or change, should be covered by the claim of present patent application.
