Description

Anti-slip high-reliability water pipe joint wrench

Technical Field

The utility model relates to a prevent water pipe head spanner of high reliability that skids belongs to installation and extracting tool technical field.

Background

The installation of cutting ferrule formula fluoroplastics water pipe head needs to use the spanner to screw up or the pine moves back. In order to ensure reliable sealing performance, a high torque is necessarily required. But fluoroplastic water pipe joints have limited hardness and strength. The phenomenon of slipping is easily generated when the traditional open end wrench is adopted for screwing, and even the locking nut cracks. Therefore, the mounting torque is not increased, and it is difficult to improve the reliability of the seal. Therefore, there is a need for a slip-resistant, highly reliable water pipe joint wrench to solve the above problems.

Disclosure of Invention

Traditional open end spanner and lock nut only point contact, based on this, in order to solve above-mentioned technical problem, the utility model discloses a prevent fluoroplastics water pipe head spanner of high reliability that skids.

The specific technical scheme is as follows: the utility model provides a prevent water pipe head spanner of high reliability that skids, includes interconnect's spanner head and wrench handle, its characterized in that: the wrench head comprises a wrench opening inside, and the wrench opening comprises at least 3 stress points connected with the water pipe connector.

Furthermore, the inner wall of the wrench opening is attached to the outer wall of the water pipe connector.

Furthermore, the wrench opening is provided with an opening, and the opening is used for penetrating through the water pipe. The water pipe is generally arranged in the water pipe connector, so that the wrench can penetrate through the water pipe through the opening to reach a required station.

Further, the opening is positioned on an extension line of the wrench handle.

Furthermore, the front end of the wrench opening is provided with two limiting ends, the limiting ends are respectively positioned at two sides of the opening, the inner wall of the wrench opening and the extension lines of the two limiting ends form a hexagon, and the wrench opening comprises 5 stress points. The conventional water pipe connector is hexagonal, and the wrench opening is attached to the water pipe connector, so that 5 stress points are formed in total. The limiting end prevents the water pipe joint from being separated from the wrench opening in the operation process.

Further, the wrench head and the wrench handle are integrally formed.

Furthermore, the wrench head and the wrench handle are mutually independent and are fixed into a whole through connection.

Furthermore, the outer wall of the tail end of the wrench handle is provided with a wear-resistant layer.

The utility model has the advantages that: the utility model discloses, through increasing the stress point, avoided the phenomenon of skidding of spanner in the operation process and water pipe head, also increased the minimum moment of torsion threshold value that the fracture phenomenon appears.

Detailed Description

The present invention will be further clarified by the following description with reference to the attached drawings and specific examples, which should be understood as being merely illustrative of the present invention and not limiting the scope of the present invention, and modifications of various equivalent forms of the present invention by those skilled in the art after reading the present invention, all fall within the scope defined by the appended claims of the present application.

As shown in figure 1, the anti-slip high-reliability water pipe joint wrench comprises a wrench head 1 and a wrench handle 2. The wrench head 1 is provided with a protruding tail part, the left end of the wrench handle 2 is hollow, and the tail part of the wrench head is inserted into the left end hollow of the wrench handle and fixed by using a screw. The right end tail of the wrench handle 2 is provided with a wear-resistant layer, so that force can be applied easily when the wrench handle is used. The wrench handle 2 is an adjustable head-changing torque wrench.

The wrench head 1 is provided with an opening 11, and the opening 11 is opposite to the wrench handle 2. Two ends of the opening 11 are two symmetrical limiting ends 12, and the limiting ends are bent inwards. A wrench opening 13 is also arranged in the hand head 11, and the shape of the wrench opening 13 is the same as that of the water pipe connector. The extension line of the jaw 13 and the limit end 12 forms a hexagon. The jaw 13 has 5 stress points with the water pipe joint, as shown in fig. 3. Through practical application, taking a PVDF fluoroplastic joint with the pipe diameter of 12mm as an example, the phenomenon of slipping or cracking can occur when the traditional open-end wrench reaches 5-6 N.m. And use the utility model discloses an installation spanner, the moment of torsion is set for and still not appear above inefficacy phenomenon at 7.5 N.m.

The utility model discloses, through increasing the stress point, avoided the phenomenon of skidding of spanner in the operation process and water pipe head, also increased the minimum moment of torsion threshold value that the fracture phenomenon appears.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
