Abstract

The invention relates to the technical field of constant force unlocking, in particular to a cargo locking device capable of being unlocked with constant force. The cargo locking device comprises a locking block (1), a constant force shear pin (2) and an installation base (3). According to the cargo locking device, equipment constant force unlocking is integrated in a simple device, cost is reduced, reliability is high, and constant force unlocking of large equipment is achieved. The cargo locking device is simple and firm in mechanism, high in reliability, convenient to use, and not limited to outside conditions.

Description

The goods locking device that a kind of power of determining is unblanked

Technical field

The present invention relates to and determine power unlocking technique field, particularly relate to the goods locking device that a kind of power of determining is unblanked.

Background technology

In determining power and unblanking, there is much version both at home and abroad, generally can realize locking and release function, and release cannot be set and separate load, unblank to realize determining power, need to additionally increase different connectors, be realized by the destruction of connector, so cause that structure is excessively complicated, it is convenient not to operate, cost is higher, less economical, and is easily subject to external condition restriction.

Summary of the invention

It is an object of the invention to:

The present invention is that equipment is determined power and unblanked to provide the goods locking device that a kind of power of determining is unblanked, and simple and practical, the equipment of being applicable to is determined power and unblanked.

The technical scheme is that

The goods locking device that a kind of power of determining is unblanked, including clamping block [1], determines power shear pin [2], mounting seat [3];

Wherein, mounting seat [3] is arranged on floor, mounting seat [3] is provided with a rotating shaft, a restraint hole has respectively been opened in mounting seat [3] upper and lower, clamping block [1] is arranged on the rotating shaft of mounting seat [3], clamping block [1] can rotate around the rotating shaft of mounting seat [3], and clamping block [1] one end is stretched in goods lock slots, and clamping block [1] other end has a through hole;

During goods locking, clamping block [1] one end is stretched in goods lock slots, the through hole of clamping block [1] is corresponding with restraint hole, mounting seat [3] top, determine through hole and the restraint hole, mounting seat [3] top of power shear pin [2] traverse clamping block [1], clamping block [1] is fixed in mounting seat [3];

When goods pulling force is more than when determining the shearing force of power shear pin [2], determining power shear pin [2] and cut off, clamping block [1] rotates around the rotating shaft of mounting seat [3] and makes clamping block [1] one end produce in goods lock slots; Now, the through hole of clamping block [1] is corresponding with restraint hole, mounting seat [3] bottom, with the through hole of another Gen Dingli shear pin [2] traverse clamping block [1] and restraint hole, mounting seat [3] bottom, clamping block [1] is fixed in mounting seat [3], it is prevented that the unexpected rotating shaft around mounting seat [3] of clamping block [1] rotates.

The invention has the beneficial effects as follows:

Equipment is determined power and is unblanked to be integrated in a simple device by the present invention, reduces cost, and reliability is high, it is achieved big equipment is determined power and unblanked. Mechanism is simple, and firmly, reliability is high, easy to use, is not limited by external condition.

Fig. 2 is the left view of the present invention.

Fig. 3 is the top view of released state of the present invention.

Detailed description of the invention

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

The goods locking device that a kind of power of determining is unblanked, as shown in Figure 1, 2, 3, including clamping block [1], determines power shear pin [2], mounting seat [3];

As shown in Figure 1, during goods locking, clamping block [1] one end is stretched in goods lock slots, the through hole of clamping block [1] is corresponding with restraint hole, mounting seat [3] top, determine through hole and the restraint hole, mounting seat [3] top of power shear pin [2] traverse clamping block [1], clamping block [1] is fixed in mounting seat [3];

When goods pulling force is more than when determining the shearing force of power shear pin [2], determining power shear pin [2] and cut off, clamping block [1] rotates around the rotating shaft of mounting seat [3] and makes clamping block [1] one end produce in goods lock slots; Now as shown in Figure 3, the through hole of clamping block [1] is corresponding with restraint hole, mounting seat [3] bottom, with the through hole of another Gen Dingli shear pin [2] traverse clamping block [1] and restraint hole, mounting seat [3] bottom, clamping block [1] is fixed in mounting seat [3], it is prevented that the unexpected rotating shaft around mounting seat [3] of clamping block [1] rotates.

Claims

1. the goods locking device that power is unblanked be can determine for one kind, it is characterised in that include clamping block [1], power shear pin [2], mounting seat [3] determined;
