Description

Crank type inner hexagon spanner

Technical Field

The utility model belongs to the repair tools field, concretely relates to crank formula allen key.

Background

The socket head screw has the characteristics of large contact surface, uniform stress, firm fixation and difficult damage, and is widely applied, and the socket head wrench is a tool for the screw. However, the currently marketed L-shaped allen key is not easy to rotate and screw continuously for 360 degrees, and is inconvenient to use under some conditions such as blocking by obstacles and needing to close the valve quickly. Particularly in the field of air conditioners, R32 has many advantages as a new generation of energy-saving, carbon-reducing, environment-friendly and nontoxic refrigerant used by the air conditioners, but is flammable and explosive, requires to close a valve during maintenance and installation, and can not take more than 1 minute for fluorine collection, otherwise serious accidents can be caused.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect among the prior art, provide a crank formula allen key.

The utility model discloses a realize above-mentioned purpose, adopt following technical scheme:

a crank type inner hexagonal wrench comprises an inner hexagonal rod, a connecting rod vertically connected with the inner hexagonal rod and a hexagonal rod vertically connected with the connecting rod;

the inner hexagonal rod: connecting rods: the length ratio of the hexagonal rod is 1-8: 2-9: 3-10, and the length of the inner hexagonal rod is less than that of the connecting rod; the length of the connecting rod is less than that of the hexagonal rod.

Preferably, the hexagonal socket head cap comprises: connecting rods: the length proportion of the hexagonal rod is 3: 5: 6.

the hexagonal rod and the connecting rod are connected through welding or are integrally formed.

The hexagonal rod is rotatably connected to the hexagonal rod on the connecting rod; the hexagonal rod is fixed on the connecting rod through a rotating pin.

The hexagonal rod is provided with a locking groove; the connecting rod is provided with a locking pin matched with the locking groove; one end of the locking pin is fixedly connected with the elastic body, and the other end of the locking pin is detachably arranged in the locking groove.

And a handle is arranged on the locking pin.

The locking groove be two or more.

Compared with the prior art, the beneficial effects of the utility model are that:

use the utility model discloses crank formula allen key can 360 rotatory wrong screws in quick succession, can be reliable closing valve rapidly. Preferably, the hexagonal rod is rotatably connected to the connecting rod, the hexagonal rod and the connecting rod are arranged at different angles, when the hexagonal rod and the connecting rod form an angle of 90 degrees, namely a Z-shaped handle is formed, the obstacle can be prevented from blocking, when the hexagonal rod and the connecting rod form an angle of 0 degree, namely an L-shaped handle is formed, the moment is increased, the hexagonal rod can be tightened more tightly when finally screwing the screw, meanwhile, the inner hexagonal rod is lengthened, the screw in a deeper hole can be screwed, and one tool can be used for multiple purposes, convenience and rapidness. The working efficiency and the safety are greatly improved, and the occurrence of accidents is reduced.

Fig. 1-3 are schematic diagrams of the overall structure of the crank type internal hexagonal wrench of the present invention;

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

Fig. 1 shows a crank type internal hexagonal wrench, which comprises an internal hexagonal rod 1, a connecting rod 3 vertically connected with the internal hexagonal rod, and a hexagonal rod 2 vertically connected with the connecting rod; the inner hexagonal rod: connecting rods: the length ratio of the hexagonal rod is 1-8: 2-9: 3-10, and the length of the inner hexagonal rod is less than that of the connecting rod; the length of the connecting rod is less than that of the hexagonal rod. In this embodiment, the hexagonal socket head cap comprises: connecting rods: the length proportion of the hexagonal rod is 3: 5: 6. use the utility model discloses crank formula allen key can 360 rotatory wrong screws in quick succession, can be reliable closing valve rapidly.

2-3 show another embodiment, a crank type internal hexagonal wrench, which comprises an internal hexagonal rod 1, a connecting rod 3 vertically connected with the internal hexagonal rod, and a hexagonal rod 2 rotatably connected with the connecting rod; the hexagonal rod is fixed on the connecting rod through a rotating pin 9; the inner hexagonal rod and the connecting rod can be of an integral structure formed by bending and can also be formed by welding. As one of the embodiments, the locking groove 8 is arranged on the hexagonal rod; the connecting rod on be provided with locking pin 7 that locking groove match, the one end of locking pin and the 4 fixed connection of one end of elastomer, the setting of the removable setting of pulling of the other end is in locking inslot. The other end of the elastic body is fixed on the connecting rod; a handle 5 is arranged on the locking pin. The locking groove be two or more. The utility model discloses a use principle of crank formula allen key does: when the hexagonal rod is used, the handle 5 is pulled, the locking pin 7 presses the elastic body under the action of the handle, the locking pin 7 is separated from the locking groove 8, the hexagonal rod can rotate around the rotating pin, and the position change between the hexagonal rod and the connecting rod is realized; when rotatory to required position, for example loosen handle 5 when hexagonal pole becomes 90 with the connecting rod, stop pin 7 gets back to under the effect of the spring body in locking groove 8, the location of hexagonal pole has been realized, when forming Z type handle, can avoid the barrier to block, it is same, through the setting of the different positions of locking groove, can realize the position location between hexagonal pole and the connecting rod, when hexagonal pole becomes 0 with the connecting rod, when forming L type handle promptly, moment has been increased, it is inseparabler to enable it when screwing the screw at last, interior hexagonal pole lengthens simultaneously, can twist the screw in the more deep hole, use the utility model discloses crank formula allen key can 360 rotatory screws in quick succession, can reliable closing valve rapidly, a instrument realizes multiple use, convenient and fast. The working efficiency and the safety are greatly improved, and the occurrence of accidents is reduced.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
