CN205089102U - Take safety protection's cabinet door lock that evaporates - Google Patents

Abstract

The utility model provides a take safety protection's cabinet door lock that evaporates, including hasp box, spring bolt, handle, pivot. The hasp box is installed on the door frame, and there is the flank of tooth inboard. Spring bolt outside part has a flank of tooth, and spring bolt and lock link together, pivot, install on the cabinet door through the pivot. At the door closure state, through rotate the lock, make the spring bolt rotate, the spring bolt combines or the separation with the hasp box, realizes that the cabinet door is by the locking or open. Opening when evaporating the cabinet door, be higher than the external pressure if evaporate the cabinet internal pressure, the cabinet goalkeeper receives outside thrust, and this thrust is used in on the lock for the spring bolt closely meshes with the flank of tooth part of hasp. Because the special structure of this kind of profile of tooth face, resistance, especially thrust are bigger producing, the resistance is big more to rotate the lock, that is when having pressure in evaporating the cabinet, the cabinet door of hardly opening or do not open to safety protection's function has been realized.

Description

A kind of steamer door lock with security protection

Technical field

The utility model relates to technical field of kitchen wares, especially relates to a kind of pressure steamer door lock.

Background technology

Often have high-pressure high-temperature steam in steamer, open cabinet door must to wait until in cabinet pressure be reduced to outdoors pressure time.When cabinet internal memory opens cabinet door under stress situations, this high-temperature steam can spray, and may scald personnel, there is potential safety hazard; Current steamer door lock does not all have safety device usually, and when having pressure in steamer, door lock is also easily opened, and there is the possibility of maloperation.Particularly when pressure in steamer is higher, open cabinet door, danger is larger by mistake, and even door can flick rapidly, not only there is steam and overflows scald personnel risk, even there is door and wound the risk that security incident occurs personnel.

Summary of the invention

The technical problem that the utility model solves is to provide a kind of Novel steam cabinet door lock, to solve the problem proposed in above-mentioned background technology.

The technical problem that the utility model solves realizes by the following technical solutions: a kind of steamer door lock with security protection, comprising: keeper, dead bolt, handle, rotating shaft; Keeper is fixed on the doorframe of steamer, and dead bolt, handle, rotating shaft are integrated, and rotating shaft is arranged in the rotating shaft cover on door.

Described keeper is snap close box body and the keeper flank of tooth.

Described dead bolt is lock tongue body and the dead bolt flank of tooth.

The inboard geared surface of keeper, dead bolt exterior portion geared surface, under door closure state, by rotation lock handle, dead bolt is rotated, dead bolt enters keeper or exits keeper, and cabinet goalkeeper is blocked or removes locking.

Cabinet door is under the state of locking, and the inner toothed surface of keeper and the outer flank of tooth of dead bolt engage each other; If pressure is higher than outdoors in steamer, this pressure can act on door, and acts on keeper by dead bolt, and dead bolt is subject to the reaction force of keeper simultaneously; Rotation lock time, the power acted on lock handle is applied to the keeper flank of tooth by the dead bolt flank of tooth, because the flank of tooth is inclined-plane, this active force can produce component in the direction of vertical gate plane, only have when this component is greater than the active force of the door that dead bolt is subject to, dead bolt just can be thrown off engagement, be rotated, and Men Caineng is opened.In steamer, pressure is larger, open to need rotating lock tongue power also larger, Men Yuenan opens.

When needing locking door, because in steamer, pressure is equal with ambient pressure, door can easily be closed, at this moment rotation lock handle, and dead bolt rotates thereupon and enters keeper, and door is blocked.

Compared with prior art, the beneficial effects of the utility model are: if pressure is higher than outdoors in steamer, door lock can not be opened easily, particularly pressure is higher, it is more difficult to open, thus prevent there is pressure in steamer, particularly maloperation in high temperature, high steam situation, open door, avoid the possibility occurring security risk.

Fig. 3 is lock bolt structure schematic diagram of the present utility model.

Detailed description of the invention

In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.

As shown in Figures 1 to 3, a kind of steamer door lock with security protection, by: the keeper flank of tooth 1, snap close box body 2, the dead bolt flank of tooth 3, lock tongue body 4, door knob 5, rotating shaft 6 form.

Snap close box body 2 is arranged on steamer doorframe, and rotating shaft 6 is arranged on steam cabinet door by axle sleeve.

Inwardly push 5, door is finally closed, and counter-clockwise direction rotary door is 5, and lock tongue body 4 rotates thereupon, and enters in keeper body 2, and the keeper flank of tooth 1 and the dead bolt flank of tooth 3 engage, and door is blocked.Clockwise direction rotary door is 5, and lock tongue body 4 exits snap close box body 2 thereupon, and door is removed locking, and be pulled outwardly door knob 5, door is opened.

Door be in pressure in locking states, steamer be greater than outdoors pressure time, door is subject to outside thrust, and this thrust, on lock tongue body 4, acts on the keeper flank of tooth 1 further by the dead bolt flank of tooth 3.When rotary door produces torsion 5, torsion acts on the keeper flank of tooth 1 by the dead bolt flank of tooth 3, the dead bolt flank of tooth 3 is subject to reaction force simultaneously, because the flank of tooth is inclined-plane, this reaction force produces component in the normal direction of the plane of lock tongue body 4, only have when this component be greater than door outside, the thrust acted on lock tongue body 4 time, the keeper flank of tooth 1 and the dead bolt flank of tooth 3 could depart from engagement, door remove locking states.Known, in steamer, pressure is higher than outdoors, and door lock can not be opened easily, and particularly pressure is higher, and it is more difficult to open, thus prevents in the maloperation under stress situations of steamer internal memory, opens door, avoids the possibility occurring security risk.

More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; such as, profile of tooth, these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
