Technical Field

The utility model belongs to the technical field of the latch hook, concretely relates to latch hook device.

Background

Along with economic life's development, the latch hook begins to use the square face of life, no matter be domestic or industrial production processing or engineering building all leave the latch hook device, and traditional latch hook relies on the elasticity of spring to reset, and the structure is complicated, and easy damage, and installation and overhaul are all inconvenient, and not high with the cooperation degree of other transport work pieces (like the arm of force) moreover for the production procedure is loaded down with trivial details, greatly increased the degree of difficulty and the manufacturing cost of processing.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a latch hook device to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a latch hook device, includes latch hook, hasp round pin, hasp and bottom plate, the arc mouth below of latch hook is through latch hook round pin and hasp swing joint, the vertical latch hook that is connected with in latch hook below erects the arm, and latch hook erects arm below horizontally connect with the latch hook xarm, the peripheral cover of latch hook xarm is equipped with the xarm dustcoat, and the inside xarm hydro-cylinder that is provided with of xarm dustcoat, xarm hydro-cylinder one end and latch hook xarm connection, the other end and xarm dustcoat connection, the xarm dustcoat is kept away from latch hook and is erected arm one end and be connected with wedge connecting piece.

Preferably, a turnover oil cylinder is arranged in the bottom plate.

Preferably, the front end of the overturning oil cylinder is arranged corresponding to the lower inclined plane of the wedge-shaped connecting piece and can push the wedge-shaped connecting piece to rotate centripetally.

Preferably, one end of the lock catch is light, and the other end of the lock catch is heavy, and is in a state of being low at the left side and high at the right side under the condition of not turning over.

The utility model discloses a technological effect and advantage: the lock hook device is simple in structure and convenient to operate, self-locking and automatic releasing of products to be carried are achieved through the dead weight of the lock catch and the matching overturning of the cross arm and the vertical arm, labor cost and production cost are reduced, and working efficiency is greatly improved.

fig. 2 is the utility model discloses latch hook upset back sketch map.

In the figure: 1. a latch hook; 2. a latch pin; 3. locking; 4. a latch hook vertical arm; 5. a latch hook cross arm; 6. a cross arm outer cover; 7. a cross arm oil cylinder; 8. a base plate; 9. turning over the oil cylinder; 10. a wedge connector; 11. a connector pin.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. 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 as shown in figure 1, figure 2 latch hook device, including latch hook 1, hasp round pin 2, hasp 3 and bottom plate 8, latch hook 1's arc mouth below is through hasp round pin 2 and 3 swing joint of hasp, the vertical latch hook that is connected with in latch hook 1 below erects arm 4, and latch hook erects arm 4 below horizontally connected with latch hook xarm 5, 5 peripheral covers of latch hook xarm are equipped with xarm dustcoat 6, and 6 inside xarm hydro-cylinders 7 that are provided with of xarm dustcoat, 7 one end of xarm hydro-cylinder are connected with latch hook xarm 5, and the other end is connected with xarm dustcoat 6, xarm dustcoat 6 keeps away from latch hook and erects 4 one end of arm and is connected with wedge connecting piece 10, and wedge connecting piece 10 passes through connecting piece round.

Specifically, a turnover oil cylinder 9 is arranged inside the bottom plate 8.

Specifically, the front end of the overturning oil cylinder 9 is arranged corresponding to the lower inclined surface of the wedge-shaped connecting piece 10 and can push the wedge-shaped connecting piece 10 to rotate centripetally.

Specifically, the lock catch 3 has a light end and a heavy end, and is in a state of being low at the left and high at the right without being turned over.

The working principle is as follows: the latch hook device is characterized in that due to different counterweight proportions, a latch 3 is in a state of being low at left and high at right under the condition that a vertical latch hook arm is not overturned, the latch 3 is pushed open in the process that a pipe fitting enters the interior of the latch 1 from an arc opening of the latch 1, when the pipe fitting reaches the interior of the latch 3, the latch 3 automatically resets, then an cross arm oil cylinder 7 contracts, a cross arm oil cylinder 9 synchronously drives a latch cross arm 5 to be withdrawn into a cross arm outer cover 6, meanwhile, a vertical latch hook arm 4 approaches one side of the cross arm outer cover 6, when the pipe fitting reaches a certain position, the cross arm oil cylinder 7 stops moving, a piston rod of an overturning oil cylinder 9 begins to extend out and continuously approach and push a wedge-shaped connecting piece 10, because one end of the wedge-shaped connecting piece 10 is rotationally fixed, the overturning oil cylinder 9 enables the wedge-shaped connecting piece 10 to drive the latch 1, the, so that the lock catch 3 is in a horizontal state, the arc opening of the lock hook 1 is in an unrestricted state, and the pipe fitting is taken away at the moment.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
