Description

Clamp for fire control

Technical Field

The present utility model relates to a fire-fighting apparatus, and more particularly, to a fire-fighting clamp.

Background

In the operation process of extinguishing fire, in order to improve the fire extinguishing efficiency and ensure the safety of firefighters, the firefighters such as a water cannon, a foam cannon and the like should be kept as close to the fire point as possible, and the firefighters should be kept as far away from the fire point as possible. A fixing device capable of fixing the fire monitor at a near fire point is necessary.

For buildings with enclosures, or fires inside the building, or already collapsed fires, it is often not possible to find a flat location to place the fire monitor within the range of the fire monitor. The solution is to provide a fixture, which is clamped and fixed on a section bar, a broken wall and the like, and then a fire monitor is fixed on the fixture.

However, the existing clamp has the defect that the applicable scene is too narrow, and is only suitable for clamping I-steel and broken walls, and when the surface profile of a clamped object has radian, or when the diameter of the clamped object is smaller, the prior art is not applicable. In addition, the existing clamp has the advantages that only two clamping jaws provide clamping force after clamping, and few stress points are needed, so that the clamping is not stable enough.

Disclosure of Invention

Preferably, in the fire-fighting clamp, the second clamping jaw is fork-shaped, and a space is arranged in the middle; the thickness of the second clamping jaw is matched with the interval.

Preferably, in the fire-fighting clamp, the screw is inclined with respect to the fixing rod.

As described above, the fixture for fire control greatly expands the applicable scene of the fire monitor, ensures that fire fighters can fix fire fighting equipment at a near fire point under more scenes and the fire fighters can be far away from the fire point, ensures the fire extinguishing efficiency and the personnel safety, and is quicker and more convenient to assemble during use.

Detailed Description

Other advantages and effects of the present utility model will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present utility model with reference to specific examples. The utility model may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present utility model.

Please refer to the accompanying drawings. It should be noted that, the illustrations provided in the present embodiment merely illustrate the basic concept of the present utility model by way of illustration, and only the components related to the present utility model are shown in the drawings and are not drawn according to the number, shape and size of the components in actual implementation, and the form, number and proportion of the components in actual implementation may be arbitrarily changed, and the layout of the components may be more complex.

Referring now to fig. 1, fig. 1 is a perspective view of an embodiment of the present utility model. The fire-fighting clamp comprises a fixed rod 1, clamping

jaws

2 and 3. The shaft of the fixed rod 1 is provided with a plurality of positioning holes 11.

The upper end of the clamping jaw 2 is provided with a through hole, and the size of the through hole is slightly larger than the cross section size of the fixed rod 1, so that the clamping jaw 2 can be sleeved on the fixed rod 1 and slide. The sidewall of the through hole includes a pin hole. When the clamping jaw 2 slides on the fixing rod 1 to the point that the pin hole is overlapped with the positioning hole 11, the clamping jaw 2 can be locked at the corresponding position of the fixing rod 1 by using the fixing pin 12 to pass through the pin hole and the positioning hole 11. The upper end of the clamping jaw 3 also comprises a through hole, the side wall of the through hole also comprises a pin hole, and the matching and working mode of the through hole and the fixed rod 1 are similar to those of the clamping jaw 2, and are not repeated.

The

clamping jaws

2 and 3 respectively comprise clamping

jaw arms

21 and 31, and the

clamping jaw arms

21 and 31 are obliquely arranged, and the oblique directions are opposite. When the device is used, coarse adjustment can be realized by sliding the

clamping jaws

2 and 3. However, considering that the sizes of the objects to be clamped on site are random, a fine adjustment mechanism is required to enable the clamp to be suitable for clamping various clamped objects. The fine adjustment mechanism comprises a support 4 and a screw rod 5. The support 4 can be fixed on the fixing rod 1, but in order to enhance the adaptability of the clamp, the upper end of the support 4 in this example is also provided with a through hole and a pin hole similar to the upper end of the clamping jaw 2, so that the support 4 can also slide on the fixing rod 1 and can be fixed on the fixing rod 1 through the fixing pin 12. Screw holes are formed in the lower portion of the support 4, screw threads matched with the screw holes are formed in the screw rod 5, one end of the screw rod 5 penetrates through the screw holes and then abuts against the clamping jaw arm 31, and a rotating handle is arranged at the other end of the screw rod. Thus, by rotating the handle, the displacement of the screw rod 5 in the direction approaching or separating from the clamping jaw arm 31 can be precisely controlled, and the clamping force of the clamping jaw arm 31 can be precisely controlled. Preferably, the screw 5 is also set at an oblique angle as shown in fig. 1, and can provide a larger clamping force in cooperation with the oblique jaw arm 31.

Compared with the design that the clamping jaw arms are perpendicular to the fixed rod, the

clamping jaw arms

21 and 31 are of an inclined design, so that the fixed rod and the two clamping jaws provide clamping force in a clamping state of the clamp, the clamping points form a triangle, clamping is stable, and particularly when the surface of a clamped object is in an arc shape shown in fig. 2 or the section of the clamped object is in a V shape shown in fig. 3, the scheme of the utility model has more obvious stability advantage compared with the prior art.

Preferably, the clamping jaw arm 21 in this example is fork-shaped, a space 22 is arranged in the middle, the thickness of the clamping jaw arm 31 is matched with the space 22 of the clamping jaw arm 21, when the clamping jaw 2 and the clamping jaw 3 are mutually close along the fixed rod 1, the clamping jaw arm 31 can penetrate through the space 22, so that the two clamping jaws can mutually match to clamp a support with a smaller diameter, and the effect is shown in a schematic view in fig. 4.

In summary, when the embodiment is used, in the clamping state, the fixing rod and the clamping jaw arm participate in clamping together, and the clamping points form a triangle, so that the clamping device has better stability, is particularly suitable for a clamped object with an arc-shaped surface, and is wider in application range. According to a preferred embodiment, the jaw arms are capable of intersecting each other and are also suitable for small diameter objects to be clamped.

The above embodiments are merely illustrative of the principles of the present utility model and its effectiveness, and are not intended to limit the utility model. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the utility model. It is intended that all equivalent modifications and variations of the utility model be covered by the claims of this utility model be accomplished by those of ordinary skill in the art without departing from the spirit and scope of the utility model as disclosed herein.
