Description

Technical Field

[0001] The utility model relates to the technical field of gas equipment, in particular to a gas valve key that can be tiltably clamped. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] Buried valves are safety devices for gas pipeline projects. They are used to cut off, connect, and regulate gas in the pipeline. They have good control characteristics and closing and sealing performance. When a gas hazard occurs, the buried valve can be urgently closed through the valve opening and closing key to reduce leakage.

[0004] The current gas valve key cannot be connected to the gas valve stem in an inclined position, which requires sufficient operating space around it when in use. However, in actual use, due to limited space, obstacles, etc., there are situations where the gas valve key cannot be connected to it from directly above the gas valve stem. As a result, in this case, the valve cannot be closed in time, increasing the risk of gas explosion. Utility Model Content

[0005] The purpose of the present utility model is to address the above-mentioned shortcomings and provide a gas valve key that can be tilted and clamped to achieve the purpose of tilting and clamping the gas valve stem.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solution: a gas valve key that can be tilted and clamped, comprising:

[0007] Collet, used to clamp the gas valve stem;

[0008] A handle for a person to hold;

[0009] The universal connection assembly is provided between the chuck and the handle and is used to maintain torque transmission when the chuck and the handle are deflected.

[0010] Furthermore, the universal connection assembly includes a first sleeve connected to the handle, a second sleeve is provided at the bottom of the first sleeve, which is inserted into the first sleeve and can move up and down, the bottom of the second sleeve is connected to the chuck, the internal aperture of the first sleeve is larger than the outer diameter of the second sleeve, the second sleeve is provided with a pin that passes horizontally through the first sleeve, and the first sleeve is provided with a strip hole for the pin to move up and down.

[0011] Furthermore, the second sleeve is rotatably provided with two L-shaped top blocks for pushing the second sleeve to rotate and deflect around the latch, and the two L-shaped top blocks are mirror-symmetrical about the axis of the first sleeve. A screw sleeve is rotatably provided on the first sleeve, and an external thread groove adapted to the screw sleeve is provided on the first sleeve. A top ring capable of moving up and down with the screw sleeve is rotatably provided at the bottom end of the screw sleeve, and the top ring is in the shape of an inverted frustum, and the maximum distance between the top ends of the two L-shaped top blocks is not less than the outer diameter of the top ring;

[0012] One end of the L-shaped top block is tilted upward and away from the first sleeve, and the other end of the L-shaped top block is tilted downward and toward the second sleeve and abuts against the second sleeve. The rotation center of the L-shaped top block is located in the middle. When the top ring moves downward, it can enter the gap between the L-shaped top block and the first sleeve and squeeze the top of the L-shaped top block, so that the second sleeve is pushed to the center by the L-shaped top blocks on both sides.

[0013] Furthermore, at least one groove for avoiding the L-shaped top block is opened at the bottom end of the top ring, so that when the top ring moves downward and one of the L-shaped top blocks is in the groove, the other L-shaped top block abuts against the second sleeve and pushes the second sleeve to deflect to one side.

[0014] Furthermore, a convex block opposite to the groove is provided at the bottom end of the top ring. When the convex block moves downward, it can enter the gap between the L-shaped top block and the first sleeve and squeeze the top of the L-shaped top block.

[0015] The beneficial effects of the present invention are as follows:

[0016] The utility model adds a universal connection component between the chuck and the handle, so that the chuck can be connected to the gas valve stem away from the rotation center of the handle, and the handle continues to rotate to transmit torque, thereby driving the gas valve stem clamped by the chuck to rotate. In this way, when faced with a situation where maintenance space is limited, the gas valve key can be used to close the gas valve in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-2 The utility model discloses a gas valve key that can be tiltably clamped, comprising:

[0023] Chuck 1, used to clamp the gas valve stem;

[0024] Handle 2, for people to hold;

[0025] The universal connection assembly 3 is provided between the chuck 1 and the handle 2 and is used to maintain torque transmission when the chuck 1 and the handle 2 are deflected.

[0026] The utility model adds a universal connection assembly 3 between the chuck 1 and the handle 2, so that the chuck 1 can be connected to the gas valve stem away from the rotation center of the handle 2, and continue to rotate through the handle 2 to transmit torque, thereby driving the gas valve stem clamped by the chuck 1 to rotate, so that when faced with a situation where maintenance space is limited, the gas valve key can be used to close the gas valve in time.

[0027] In one embodiment, the universal connection assembly 3 includes a first sleeve 31 connected to the handle 2, and a second sleeve 32 is provided at the bottom of the first sleeve 31, which is inserted into the first sleeve 31 and can move up and down. The bottom of the second sleeve 32 is connected to the chuck 1, and the internal aperture of the first sleeve 31 is larger than the outer diameter of the second sleeve 32. The second sleeve 32 is provided with a pin 33 that passes through the first sleeve 31 horizontally, and the first sleeve 31 is provided with a strip hole for the pin 33 to move up and down.

[0028] This design utilizes the gap between the first sleeve 31 and the second sleeve 32 to allow the second sleeve 32 to swing around the latch 33. Due to the provision of the strip hole on the first sleeve 31, when there is a deflection between the first sleeve 31 and the second sleeve 32, the movable range of the strip hole can be utilized to move the latch 33 within the strip hole when the first sleeve 31 rotates, completing the torque transmission between the first sleeve 31 and the second sleeve 32 when rotating in this state, ensuring that the gas valve key can drive the gas valve stem to rotate even when it is tilted and clamped.

[0029] In one embodiment, two L-shaped top blocks 34 are rotatably provided on the second sleeve 32 for pushing the second sleeve 32 to rotate and offset around the latch 33. The two L-shaped top blocks 34 are mirror-symmetrical about the axis of the first sleeve 31. A screw sleeve 35 is rotatably provided on the first sleeve 31. The first sleeve 31 is provided with an external thread groove that matches the screw sleeve 35. A top ring 36 is rotatably provided at the bottom end of the screw sleeve 35 and can move up and down with the screw sleeve 35. The top ring 36 is in the shape of an inverted frustum. The maximum distance between the top ends of the two L-shaped top blocks 34 is no less than the outer diameter of the top ring 36.

[0030] One end of the L-shaped top block 34 is tilted upward and away from the first sleeve 31, and the other end of the L-shaped top block 34 is tilted downward and close to the second sleeve 32 and abuts against the second sleeve 32. The rotation center of the L-shaped top block 34 is located in the middle. When the top ring 36 moves downward, it can enter the gap between the L-shaped top block 34 and the first sleeve 31 and squeeze the top of the L-shaped top block 34, so that the second sleeve 32 is pushed to the center by the L-shaped top blocks 34 on both sides.

[0031] With this design, by rotating the top ring 36, the top ring 36 is driven to move downward to abut against the L-shaped top block 34. The L-shaped top block 34 is pushed to rotate, limiting the rotation margin of the second sleeve 32 in the first sleeve 31. In this state, the handle 2 and the chuck 1 are in the same straight line, which can meet the normal clamping and rotation requirements and make it easier for the operator to push the handle 2 to rotate when the environment is not restricted.

[0032] In one embodiment, at least one groove is defined at the bottom end of the top ring 36 for accommodating the L-shaped top block 34 , so that when the top ring 36 moves downward and one of the L-shaped top blocks 34 is in the groove, the other L-shaped top block 34 abuts against the second sleeve 32 and pushes the second sleeve 32 to deflect to one side.

[0033] In this design, the groove is adjusted to be directly above the L-shaped top block 34 by rotating the top ring 36, and then the second screw sleeve 35 is rotated to move one of the L-shaped top blocks 34 into the groove. The other L-shaped top block 34 is pushed by the top ring 36 to squeeze the second sleeve 32, causing the second sleeve 32 to rotate to the other side. In this state, the deflection angle of the handle 2 and the chuck 1 can be manually controlled, so that the adjusted gas valve key can maintain the set angle to clamp the object while taking into account other work tasks.

[0034] In one embodiment, a protrusion 37 opposite to the groove is further provided at the bottom end of the top ring 36 . When the protrusion 37 moves downward, it can enter the gap between the L-shaped top block 34 and the first sleeve 31 and squeeze the top of the L-shaped top block 34 .

[0035] This design allows one of the L-shaped top blocks 34 to move into the groove, while the other L-shaped top block 34 is pushed by the protrusion 37 , which can accelerate the L-shaped top block 34 to push the second sleeve 32 to deflect, thereby reducing the height that the top ring 36 needs to move downward.
