Abstract

The utility model discloses a clamp of a bottle respirator, which is used for clamping and fixing the bottle respirator. The clamp comprises a clamp arm I, a clamp arm II, a support, a support saddle, a cylinder and a reversing valve, wherein the support is vertically arranged on the support saddle, the clamp arm I, the clamp arm II and the cylinder are arranged on the support, the clamp arm I is fixed at the lower part between vertical rods of the support, one end of the clamp arm II is arranged above the vertical rods of the support, and a cylinder rod connecting head is arranged at the other end of the clamp arm II; the cylinder is arranged on the vertical rods of the support at one end of the clamp arm I, the cylinder rod connecting head is arranged at the top of the cylinder, and the reversing valve is arranged on the cylinder; a one-way throttle valve is further arranged on the cylinder; arc-shaped grooves are formed in the clamp arm I and the clamp arm II; and threaded holes are formed in the vertical rods of the support. According to the clamp disclosed by the utility model, the expansion, contraction and opening of a cylinder lever or the clamping of a gas cylinder can be controlled through a pneumatic principle, the weight is light, and the movement is convenient; the sufficient clamping force can be rapidly provided, and the operation is convenient; and the positions of the clamp arms can be adjusted for the gas cylinders with different diameters, and the clamping requirements of the various bottle respirators can be met.

Description

The bottle respirator fixture

Technical field

The utility model relates to a kind of fixture, especially a kind of bottle respirator fixture.

Background technology

Be gases at high pressure in the bottle respirator of fire fighter's fire-fighting and rescue back back of the body, can not directly by the fireman, be used for breathing, so need to install pressure-reducing valve additional in the bottle respirator gas outlet.After every bottle of air is finished, need to change pressure-reducing valve.When the bottle neck pressure-reducing valve is breathed in artificial dismounting, because bottle respirator is difficult for fixing, insufficient clamping force, often make pressure-reducing valve not quick detachable, dismounting easily produces potential safety hazard by force, and generally clamping device is the bottle respirator clamping that fixedly design can't adapt to each different-diameter, makes the clamping device scope of application little.

The utility model content

Be difficult for fixing, insufficient clamping force, the general little problem of the clamping device scope of application for solving bottle respirator, the utility model provide a kind of clamping force provide sufficient, easy to operate, applicable to the bottle respirator fixture of various diameter bottle respirators.

Technical problem to be solved in the utility model is achieved through the following technical solutions:

A kind of bottle respirator fixture, comprise clip arm I, clip arm II and support, also comprises bearing, cylinder, reversal valve;

Described support vertical is located on bearing, described support is provided with clip arm I, clip arm II and cylinder, described clip arm I is fixed on below between rack vertical rod, and described clip arm II one end is located at the rack vertical rod top, and the described clip arm II other end is provided with the cylinder rod connector;

Described cylinder is located on the rack vertical rod of clip arm I one end, and described cylinder head is provided with the cylinder rod connector, and described cylinder is provided with reversal valve.

Also be provided with one-way throttle valve on described cylinder.

Described clip arm I and clip arm II are provided with arc groove.

Described rack vertical rod is provided with screwed hole.

The beneficial effects of the utility model are:

The utility model passes through pneumatic principle, and stretching, open or clamping gas cylinder of control cylinder lever is lightweight, is convenient to mobile; Quick is for enough clamping forces, and is easy to operate; Gas cylinder for different-diameter passes through to adjust the clip arm position, can meet various bottle respirators and step up demand.

Description of drawings

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.

Fig. 1 is front view of the present utility model;

Fig. 2 is side view of the present utility model;

Fig. 3 is top view of the present utility model.

In figure, 1. clip arm I, 2. clip arm II, 3. support, 4. bearing, 5. cylinder, 6. reversal valve, 7. cylinder rod connector.

The specific embodiment

As shown in Figure 1-Figure 3, this bottle respirator fixture consists of clip arm I1, clip arm II2, support 3, bearing 4, cylinder 5, reversal valve 6, cylinder rod connector 7.

The bottle respirator fixture be divided into mechanical part and pneumatic part.

The mechanical part of bottle respirator fixture mainly contains clamp arm I1, clamp arm II2, support 3, bearing 4 and cylinder rod connector 7.

Bearing 4 is formed by a transverse horizontal square steel and two vertical equity square steel assembly weldings, vertical welding support 3 on the transverse horizontal square steel of bearing 4.Support 3 has two rack vertical rods and a rack cross-bar to form, two rack vertical rod height are inconsistent, and two rack vertical rod bottoms, be symmetrical arranged respectively some screwed holes, this screwed hole is used for installation and fixes to clamp arm I1, highly higher rack vertical rod top is connected with clamp arm II2, and the rack cross-bar cross bar is vertically fixed on the transverse horizontal square steel.

Clamp arm I1 upside be provided with arc groove relative to clamp arm II2 downside, clamp arm II2 one end is connected with highly higher rack vertical rod top, and the other end is installed cylinder rod connector 7.

Cylinder 5 is fixed on the highly lower rack vertical rod of support 3, and cylinder 5 tops are connected with the cylinder rod connector 7 on clamp arm II2, and reversal valve 6 and one-way throttle valve are installed simultaneously on cylinder 5.

The pneumatic part power source is the bottle respirator that carries on fire fighting truck,, by the preprepared tracheae being connected bottle respirator with reversal valve connection, can carry out work.Reversal valve 6 is preferably hand-operated direction valve, by clockwise or rotate counterclockwise the hand-operated direction valve handle, gas can enter cylinder 5, cylinder 5 can have been selected bar cylinder or Rodless cylinder, thereby make the cylinder telescopic lever, the cylinder rod connector 7 that connects by same lever makes clamp arm I clamp or unclamps bottle respirator.

Should be understood that, the above-mentioned specific embodiment of the present utility model only is used for exemplary illustration or explains principle of the present utility model, and does not form restriction of the present utility model.Therefore, in the situation that do not depart from any modification that spirit and scope of the present utility model make, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.In addition, the utility model claims are intended to contain whole variations and the modification in the equivalents that falls into claims scope and border or this scope and border.
