Description

The mechanical type container locking device

Technical field

The utility model relates to the blocking device between container cover and the container body, refers to a kind of mechanical type container locking device particularly.

Background technology

Have many containers all include one can be movable container cover, when getting thing, open container cover, the time spent is not shut container cover, this movable receptacle lid often needs a blocking device to be fixed on inactive container body.At present, container locking device commonly used or structure is very simple and crude, latch functions is relatively poor, or volume bulkiness or have appliance controling element make structure be tending towards complicated, the complex operation effort.When these blocking devices being used on the container of conventional environment, its stability, safety still can, but when using it for fields such as the special mechanical environment of vibration, impact such as Aeronautics and Astronautics, because its anti-vibration, shock resistance are relatively poor, the function of locking is easy to lose efficacy, and is difficult to satisfy the use needs of these special mechanical environments.

Summary of the invention

The purpose of this utility model is exactly that the mechanical type container locking device that a kind of structure is small and exquisite, easy to operate and have fabulous anti-vibration, shock resistance will be provided.

For realizing this purpose, the mechanical type container locking device that the utility model is designed, comprise last tapered end that is installed on the container cover and the lower lock head that is installed on the container body, last tapered end is provided with the fixedly dead bolt that extend in the lower lock head, fixedly has the tapered end perforation on the dead bolt; Have on the lower lock head with last tapered end perforation and stretch into position dead in line lower lock head through hole, the middle wall of lower lock head through hole is provided with limited ring dais; In the lower lock head through hole lock pin is installed, lock pin can put in or the end that to go up the tapered end perforation that contracts offers forward and backward position-limited trough successively, lower lock head is provided with the positioning reed that may be stuck in the forward and backward position-limited trough, forward and backward position-limited trough side is provided with the U type fork of lock pin vertical shifting relatively, one end of U type fork cooperates with the positioning reed extruding, and the other end of U type fork links to each other with the unlock button of lower lock head through hole outside; The other end of lock pin links to each other with the locking press button that is arranged on lower lock head through hole outside, and lock pin is set with retracing spring on the shaft part between locking press button and the limited ring dais.

Principle of work of the present utility model is such: retracing spring and positioning reed can be controlled the position that the lock pin in the lower lock head through hole is bored a hole with respect to last tapered end, unlock button and locking press button can make lock pin move around by the effect of retracing spring and positioning reed, thereby reach locking container and remove the purpose that container locks.

Advantage of the present utility model is: designed blocking device is made up of mechanical part fully, its compact conformation, and volume is light and handy, need not control by electric elements, operates very easy; The double reaction plus of its retracing spring and positioning reed makes blocking device have stronger anti-vibration, impact resistance, thereby it is safe in utilization, and stability, reliability is high, can be widely used on the container in the various special mechanical environments such as Aeronautics and Astronautics.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Mechanical type container locking device shown in the figure has a last tapered end 3 and a lower lock head 4 that is installed in container body 2 one sides that is installed in container cover 1 one sides, and the opposite side of container cover 1 and container body 2 is connected through the hinge.Last tapered end 3 is provided with the fixedly dead bolt 3a that extend in the lower lock head 4, fixedly has tapered end perforation 3b on the dead bolt 3a.Have on the lower lock head 4 with last tapered end perforation 3b and stretch into position dead in line lower lock head through hole 4a, the middle wall of lower lock head through hole 4a is provided with limited ring dais 4b.Among the lower lock head through hole 4a lock pin 7 is installed, before lock pin 7 can put in or the end that to go up tapered end perforation 3b of contracting offers successively, back position-

limited trough

7a, 7b, on the lower lock head 4 by screw 10 be equipped with may be stuck in before, back position-limited trough 7a, positioning reed 9 among the 7b, before, back position-limited trough 7a, the 7b side is provided with the U type fork 8 of lock pin 7 vertical shifting relatively, one end of U type fork 8 cooperates with positioning reed 9 extruding, the other end of U type fork 8 is threaded with the unlock button 5 of lower lock head through hole 4a outside, unlock button 5 and U type fork 8 are movable part, can select light material for use, as aluminium, plastics etc. are to alleviate the impact to positioning reed 8.The other end of lock pin 7 is threaded with the locking press button 6 that is arranged on lower lock head through hole 4a outside, and lock pin 7 is set with screw-shaped retracing spring 11 on the shaft part between locking press button 6 and the limited ring dais 4b, and retracing spring 11 relies on limited ring dais 4b location.

Above-mentioned upward tapered end perforation 3b and lower lock head through hole 4a can be square hole or rectangular opening, but be preferably the identical cylindrical hole of diameter, 7 of above-mentioned lock pins are the cylindrical lock pins that is complementary with cylindrical hole, the forward and backward position-limited trough 7a of this

cylindrical lock pin
