Detailed Description

The present invention will be described in detail below, and it is apparent that the technical solutions in the embodiments of the present invention are described clearly and completely. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a valve wrench for valve through the improvement, as shown in fig. 1-4, a handle bar 1, telescopic handles 2 are screwed on both ends of the handle bar 1, a connecting rod 3 is fixed on the lower surface of the handle bar 1, a loop bar 4 is slidingly sleeved on the outside of the connecting rod 3, a wrench end 5 is fixed on the lower end of the loop bar 4, two limiting plates 6 are arranged on the inner wall of the wrench end 5, a valve head 7 is clamped between the limiting plates 6, two limiting plates 6 are arranged inside the wrench end 5 at the lower end of the loop bar 4, the outer wall of the valve of the gas tank can be clamped into the outer wall of the gas tank from top to bottom, the valve head 7 can be screwed by rotating the telescopic handles 2 at both ends of the handle bar 1, thereby the valve head 7 can be screwed down from the gas tank body, and the two telescopic handles 2 can be rotated to be telescopic with the handle bar 1, thereby adjusting the length of the telescopic handles 2, so that a user can use smaller force to generate larger torque force, the principle is a lever principle, a first slot 8 is arranged on the outer wall of a loop bar 4 in a penetrating way, a second slot 9 is arranged on the outer wall of a connecting rod 3 in a penetrating way, a chain 10 is fixedly connected on the outer wall of the loop bar 4, a bolt 11 is fixedly connected at the tail end of the chain 10, the connecting rod 3 which is in sliding sleeve connection with the loop bar 4 can be adjusted to lift with the loop bar 4, the bolt 11 can penetrate through the first slot 8 on the outer wall of the loop bar 4 and the second slot 9 on the outer wall of the connecting rod 3, so that the heights of the two can be limited and fixed, the valve dismounting operation can be conveniently carried out by people with different heights, one end of the bolt 11 is connected with the loop bar 4 through the chain 10, the loss of the bolt 11 can be avoided, the use is also convenient, a limit strip 13 is fixed on the outer wall of the connecting rod 3, a sliding chute which is in sliding fit with the limit strip 13 is arranged on the inner wall of the loop bar 4, the connecting rod 3 can slide with the sliding chute on the inner wall of the loop bar 4 in the sliding lifting process with the loop bar 4, thereby avoid connecting rod 3 to take place rotatoryly at the in-process that goes up and down with loop bar 4, guarantee the stability of going up and down, the outer mouthful size of bolt 11 is identical with the interior mouthful size of first slot 8 and second slot 9, bolt 11 can tightly rather than the laminating after inserting first slot 8 and second slot 9, guarantee seamless between the two, avoid rocking the wearing and tearing that cause the mouth in the slot because of the gap, connecting rod 3 and loop bar 4's life has been improved, the 3 outer walls of connecting rod are seted up to second slot 9 equidistance, the second slot 9 that the equidistance distributes can be convenient for carry out not co-altitude between connecting rod 3 and the loop bar 4 and adjust fixedly, with the scope of high regulation is improved, make crowd's application scope wider.

As shown in fig. 1, 5 outer walls of spanner end head run through threaded connection has threaded rod 12, limiting plate 6 rotates to be connected in threaded rod 12 is terminal, the interval size between the two is adjusted in the rotation of two limiting plate 6 accessible threaded rods 12 that set up, thereby adapt to not valve head 7 dismantlement work of unidimensional size, and threaded rod 12 evil spirit all rotates limiting plate 6 of connection and can avoid taking place to rotate at the in-process that removes along with threaded rod 12, and limiting plate 6 can remove along with the guide post of 5 inner walls of spanner end head, in order to improve removal precision and stability.

The working principle is as follows: firstly, two threaded rods 12 are rotated according to valve heads 7 with different sizes to drive the tail end limiting plates 6 to move, so that the distance between the two limiting plates 6 is adjusted, then the two threaded rods are clamped into the outer wall of a valve of a gas tank from top to bottom, the clamped valve heads 7 can be screwed by rotating telescopic handles 2 at two ends of a handle 1, so that the valve heads 7 are unscrewed from the gas tank body, the two telescopic handles 2 can be rotated to be telescopic with the handle 1, so that the length of the telescopic handles 2 is adjusted, a user can use smaller force to generate larger torsion, the principle is a lever principle, finally, a connecting rod 3 which is in sliding sleeve joint with a sleeve rod 4 before the valve heads 7 are screwed can be adjusted to be lifted with the sleeve rod 4, and a bolt 11 can penetrate through a first slot 8 in the outer wall of the sleeve rod 4 and a second slot 9 in the outer wall of the connecting rod 3, thereby carry out spacing fixed with both heights, personnel that its process can make things convenient for different heights carry out the valve and dismantle the operation.
