Abstract
The utility model relates to a novel explosion-proof F wrench, which comprises a handle and a paw, wherein the paw is connected with one end of the handle; the gripper includes four symmetrical arrangement's column joint portion, joint portion has the curved surface of indent, the curved surface of indent is used for with the contact of valve hand wheel face for block valve hand wheel. The force applied by the utility model is 90 degrees with the F-shaped handle, so that the tilting moment can not be generated, the force is saved when the valve is opened, and the valve can not be damaged by extrusion; the claw of the F wrench is in curved surface contact with the valve hand wheel, so that the antirust paint on the surface of the valve hand wheel cannot be damaged; the middle part of the paw of the F wrench is an inwards concave curved surface, so that a valve hand wheel is clamped, and the occurrence of injury accidents of operators caused by the fact that the wrench slips when the valve is opened can be reduced.
Description
Technical Field
The utility model belongs to the technical field of the chemical industry, especially, relate to a novel explosion-proof F spanner.
Background
The common F wrench is named after the shape of a product is like an English letter F and is used for opening a valve, the F wrench is a necessary tool in equipment installation, device and equipment maintenance and repair work, and the common F wrench is widely applied to industries such as petrifaction, machinery, power generation, natural gas, mines and the like.
The common F wrench is a frequently used tool in petrochemical enterprises and is used for opening a heavy manual valve. When the ordinary F spanner is used for opening the valve, the spanner is easy to slip due to the fact that the inclined torque is applied and the spanner is in point contact with the hand wheel, and therefore operators are injured. The F spanner is contacted with the valve hand wheel point and is easy to destroy the anti-rust paint on the surface of the hand wheel, and the valve is required to be frequently re-brushed with the anti-rust paint subsequently, so that time and labor are wasted, and the production cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a novel explosion-proof F spanner to solve above-mentioned technical problem.
The utility model provides a novel explosion-proof F wrench, which comprises a handle and a paw, wherein the paw is connected with one end of the handle; the gripper comprises four symmetrically arranged columnar clamping portions, the clamping portions are provided with concave curved surfaces, and the concave curved surfaces are used for being in surface contact with the valve hand wheel and used for clamping the valve hand wheel.
Further, the paw still includes connecting portion, and connecting portion one end is connected with joint portion one end, and the other end is connected with the handle.
Further, the clamping part is made of an explosion-proof copper alloy material.
By means of the scheme, the novel explosion-proof F wrench has the advantages that the force applied by the novel explosion-proof F wrench is 90 degrees to the F wrench handle, so that the tilting moment can not be generated, the force is saved when the valve is opened, the valve can not be extruded and damaged, and the service life of the valve is prolonged; the claw of the F wrench is in curved surface contact with the valve hand wheel, so that the antirust paint on the surface of the valve hand wheel cannot be damaged; the middle part of the paw of the F wrench is an inwards concave curved surface, so that a valve hand wheel is clamped, the occurrence of injury accidents of operators caused by the fact that the wrench slips when the valve is opened is reduced, and the safety coefficient of operation is improved.
The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.
Drawings
Fig. 1 is a schematic structural view of a novel explosion-proof F wrench of the present invention;
fig. 2 is an operation schematic diagram of the novel explosion-proof F wrench of the present invention.
Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
Referring to fig. 1 and 2, the embodiment provides a novel explosion-proof F wrench, which includes a handle 1 and a claw, wherein the claw is connected to one end of the handle 1; the gripper includes four symmetrical arrangement's column joint portion 21, and joint portion 21 has the curved surface 211 of indent, and the curved surface 211 of indent is used for with 3 face contact of valve hand wheel for block valve hand wheel 3.
Through the novel explosion-proof F wrench, the force F applied is 90 degrees to the handle, so that the tilting moment can not be generated, the force is saved when the valve is opened, the valve can not be extruded and damaged, and the service life of the valve is prolonged; the paw is in curved surface contact with the valve hand wheel, so that the antirust paint on the surface of the valve hand wheel is not damaged; the middle part of the paw is an inwards concave curved surface, so that a valve hand wheel is clamped, the occurrence of injury accidents of operators caused by the fact that a wrench slips when the valve is opened is reduced, and the safety factor of operation is improved.
In this embodiment, the paw further comprises a connecting portion 22, one end of the connecting portion 22 is connected with one end of the clamping portion 21, and the other end is connected with the handle 1. Simple structure and easy realization.
In the present embodiment, the clip portion 21 is made of an explosion-proof copper alloy material, and does not generate sparks at the time of impact or friction.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
