Abstract

The utility model discloses a door lock device for on hatch door, a serial communication port, including unlocking device, interior handle, outer handle, the lock body, first connecting rod, the spring bolt is gone up to the second connecting rod, and the lock tube is gone up, lower lock tube to lower spring bolt, the first connecting rod one end and the hypogloeeis end rigid coupling of locking, one end is articulated with the lock core in the lock body, second connecting rod one end and spring bolt upper end rigid coupling down, the other end is articulated with the lock core in the lock body, and go up spring bolt and spring bolt down and be recess formula spring bolt, the groove opening of recess formula spring bolt is towards the hatch door, the upper end of going up the relative open end of spring bolt department hinges there is the gyro wheel, the lower extreme of the relative opening part of spring bolt hinges and has the gyro wheel down, goes up spring bolt and the cooperation of last lock tube, lower spring bolt and lower lock tube cooperation. This door lock device is laborsaving durable, accords with the requirement to the hatch door.

Description

A kind of for the door lock mechanism on hatch door

Technical field

This utility model belongs to mechanical engineering field and in particular to a kind of door lock mechanism on hatch door for shelter.

Background technology

With the progress of technology, the requirement more and more higher to various product for all trades and professions, different workplaces is to door lock Requirement also different, safe, laborsaving, durable is the requirement most basic to door lock, at present, it is common to use door lock be dead bolt and lock Cover the mode opposite house combining to be locked, general dead bolt is to enter lock tube by way of sliding, and sliding-frictional resistance is relatively Greatly, use time is long, dead bolt and be not easily accessible lock tube when locking a door, and during enabling, dead bolt is difficult to leave lock tube again, opens the door and relatively takes Power.

Content of the invention

For overcoming the deficiencies in the prior art, the purpose of this utility model is that offer is a kind of laborsaving, and durable, light is used for Door lock mechanism on door cabin.

The purpose of this utility model is achieved through the following technical solutions:

A kind of for the door lock mechanism on hatch door it is characterised in that include tripper, Internal handle, outer handle, lock body, First connecting rod, second connecting rod, upper lock tongue, lower dead bolt, upper lock tube, lower lock tube；First connecting rod one end is affixed with upper lock tongue lower end, and one End is hinged with the lock core in lock body, and second connecting rod one end is affixed with lower dead bolt upper end, and the other end is hinged with the lock core in lock body, on Dead bolt and lower dead bolt are groove type dead bolt, and towards hatch door at the slot opening of described groove type dead bolt, described upper lock tongue is relatively Upper end at opening is hinged with roller, and the lower end at described lower dead bolt opposed open is hinged with roller, upper lock tongue and upper lock tube Cooperation, lower dead bolt and lower lock tube cooperation.

Further, described first connecting rod and the axially external of second connecting rod are provided with protective case.

Further, below in described upper lock tongue, in lower dead bolt, the both sides of top are provided with support member and sliding sleeve, described support Part is fixed on hatch door, and described upper lock tongue and lower dead bolt are located between sliding sleeve and support member, and sliding sleeve two ends are fixed on support member. Support member and sliding sleeve have coordinated the effect protecting upper and lower dead bolt, it is to avoid dead bolt and hatch door friction.

The beneficial effects of the utility model: upper lock tongue and lower dead bolt are set to groove type structure, can mitigate the weight of dead bolt, And then the weight of mitigation hatch door, upper and lower dead bolt is all supporting to be connected with roller so that upper and lower dead bolt enters during lock tube by common cunning Move and be changed into rolling, frictional resistance is relatively small, reduces the locking moment of Internal handle and outer handle during enabling, decreases to lock The abrasion of tongue, this door lock mechanism is durable, laborsaving, meets the requirement to hatch door.

Brief description

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the partial enlarged drawing at i in Fig. 1.

Fig. 3 is the a-a of Fig. 1 to profile.

Specific embodiment

Below in conjunction with drawings and Examples, technical scheme described in the utility model is clearly and completely described, Obviously, described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on this practicality Embodiment in new, the every other reality that those of ordinary skill in the art are obtained under the premise of not making creative work Apply example, broadly fall into the scope of this utility model protection.

As Fig. 1, shown in Fig. 2, Fig. 3, a kind of for the door lock mechanism on hatch door, including Internal handle 1, outer handle 2, lock body 3, First connecting rod 4, second connecting rod 5, upper lock tongue 6, lower dead bolt 7, upper lock tube, lower lock tube；First connecting rod 4 one end and upper lock tongue 6 lower end Affixed, one end is hinged with the lock core in lock body 3, and second connecting rod 5 one end is affixed with lower dead bolt 7 upper end, in the other end and lock body 3 Lock core is hinged, and upper lock tongue 6 and lower dead bolt 7 are groove type dead bolt, towards hatch door at the slot opening of described groove type dead bolt, institute State the upper end at upper lock tongue 6 opposing opened ends and be hinged with roller 8, the lower end at described lower dead bolt 7 opposed open is also hinged with rolling Wheel 8, upper lock tongue 6 and upper lock tube cooperation, lower dead bolt 7 and lower lock tube cooperation.The two of top below in described upper lock tongue, in lower dead bolt Side is equipped with support member 10 and sliding sleeve 9, and described upper lock tongue and lower dead bolt are located between sliding sleeve 9 and support member 10 respectively, described Support member 10 is fixed on hatch door, and described sliding sleeve 9 two ends are fixed on support member.

When pinning hatch door, rotate Internal handle or outer handle, handle drives the lock core motion in lock body, and the lock core in lock body is again Make that first connecting rod moves upwards and second connecting rod moves downwards, first connecting rod interlock so that upper lock tongue under the assistance of roller to enterprising Enter the upper lock tube being fixed on doorframe, second connecting rod interlocks downwards so that lower dead bolt enters under the assistance of roller is fixed on door Lower lock tube on frame.Open hatch door in opposite direction with the gearing of locked position.Upper and lower dead bolt all enters corresponding under the assistance of roller Lock tube, the effect of early rolling friction, switch hatch door used by power also less, decrease the abrasion to dead bolt, durable laborsaving.
