Description

A kind of emergent manual kickoff mechanism

Technical field

The present invention relates to meets an urgent need manually frees technical field, particularly relates to a kind of emergent manual kickoff mechanism.

Background technology

Emergent manually free in, there is much version both at home and abroad, be generally adopted connected form, realized emergent safe separating by the destruction to connector, so cause that cost is higher, less economical, and it is certain dangerous to operate existence, convenient not. And it is easily subject to external condition restriction.

Summary of the invention

It is an object of the invention to:

The present invention provides a kind of emergent manual kickoff mechanism for emergent manually freeing, and simple and practical, being applicable to meets an urgent need manually frees.

The technical scheme is that

A kind of emergent manual kickoff mechanism, including separation member [1], base [2], separates draw ring [3], spring [4], piston rod [5], 4 steel balls [6];

Wherein, base [2] right part fore-and-aft direction has through square hole, base [2] left end center has the stepped hole of horizontal direction, and communicate with the square hole of base [2] right part, separation member [1] right-hand member center has the blind hole of horizontal direction, separation member [1] right-hand member is followed closely on the step of the stepped hole of the horizontal direction of base [2], piston rod [5] is arranged in the blind hole of separation member [1], piston rod [5] left end plush copper withstands the blind via bottom of separation member [1], piston rod [5] right-hand member is through the stepped hole of base [2] horizontal direction and stretches into the square hole of base [2] right part, separate draw ring [3] hinged with piston rod [5] right-hand member, spring [4] is enclosed within piston rod [5], spring [4] left end withstands on piston rod [5] left end plush copper, spring [4] right-hand member withstands on the step of the stepped hole of base [2] horizontal direction, separation member [1] fore-and-aft direction and above-below direction have logical circular hole and on same cross section at piston rod [5] left end plush copper place, the side-walls of the stepped hole of base [2] horizontal direction that separation member [1] fore-and-aft direction is corresponding with the logical circular hole of above-below direction is provided with a circle arcuate groove, 4 steel balls [6] are separately mounted to the logical circular hole of separation member [1] fore-and-aft direction and above-below direction, each steel ball [6] one end withstands on piston rod [5] left end plush copper, each steel ball [6] other end withstands in the arcuate groove of the sidewall of the stepped hole of base [2] horizontal direction,

When needs terminate locking, draw ring [3] will be separated draw to the right, piston rod [5] is driven to move right from draw ring [3], when piston rod [5] left end plush copper moves to steel ball [6] right side, steel ball [6] rolls in the blind hole of separation member [1], steel ball [6] relieves the locking to separation member [1], and separation member [1] departs from base [2].

The invention has the beneficial effects as follows:

Emergent manually freeing is integrated in a simple device by the present invention, reduces cost, and reliability is high, it is achieved meets an urgent need and manually frees. Mechanism is simple, and firmly, reliability is high, easy to use, is not limited by external condition.

Fig. 2 is Figure 1A-A to structure sectional view.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described in further detail:

A kind of emergent manual kickoff mechanism, as shown in Figure 1, 2, including separation member [1], base [2], separates draw ring [3], spring [4], piston rod [5], 4 steel balls [6];

Wherein, base [2] right part fore-and-aft direction has through square hole, base [2] left end center has the stepped hole of horizontal direction, and communicate with the square hole of base [2] right part, separation member [1] right-hand member center has the blind hole of horizontal direction, separation member [1] right-hand member is followed closely on the step of the stepped hole of the horizontal direction of base [2], piston rod [5] is arranged in the blind hole of separation member [1], piston rod [5] left end plush copper withstands the blind via bottom of separation member [1], piston rod [5] right-hand member is through the stepped hole of base [2] horizontal direction and stretches into the square hole of base [2] right part, separate draw ring [3] hinged with piston rod [5] right-hand member, spring [4] is enclosed within piston rod [5], spring [4] left end withstands on piston rod [5] left end plush copper, spring [4] right-hand member withstands on the step of the stepped hole of base [2] horizontal direction, separation member [1] fore-and-aft direction and above-below direction have logical circular hole and on same cross section at piston rod [5] left end plush copper place, the side-walls of the stepped hole of base [2] horizontal direction that separation member [1] fore-and-aft direction is corresponding with the logical circular hole of above-below direction is provided with a circle arcuate groove, 4 steel balls [6] are separately mounted to the logical circular hole of separation member [1] fore-and-aft direction and above-below direction, each steel ball [6] one end withstands on piston rod [5] left end plush copper, each steel ball [6] other end withstands in the arcuate groove of the sidewall of the stepped hole of base [2] horizontal direction,

During use, in the locked state, due to the spring [4] effect to piston rod [5], piston rod 5 is made] will not surprisingly move horizontally when not stressing and unblock situation occurs; When needs terminate locking, draw ring [3] will be separated draw to the right, piston rod [5] is driven to move right from draw ring [3], when piston rod [5] left end plush copper moves to steel ball [6] right side, steel ball [6] rolls in the blind hole of separation member [1], steel ball [6] relieves the locking to separation member [1], and separation member [1] departs from base [2].
