Abstract
The invention discloses a plug for an elevator, which comprises a longitudinal semi-frame handrail body arranged on the cabin wall of the cabin of the elevator transversely, wherein the handrail body comprises an upper horizontal surface, a main surface and a lower horizontal surface. The plug is characterized in that: the main surface of the handrail body is provided with a control panel which is connected with the circuit of a control device which controls the operation of the cabin of the elevator. With the control panel arranged on the handrail, the plug of the invention has the advantages of simple structure, compactness and the like. Arranged on the upper half part, which is inclined backward, of the handrail, the control panel helps to avoid the misoperaiton of a passenger when the passenger arrives and has the advantages of direct display panel, large view field and the like.
Description
Technical field
The present invention relates to a kind of latch, in particular for the latch of elevator.
Background technology
Existing machine-roomless lift is when repair apparatus, and normally service personnel enters elevator, and overhaul at the top of lift stand car.Lift car can move up and down along car guide rail by suspension rope.Because the direction all around of lift car is all fixing, therefore when maintenance, certain rocking can take place, though this rocking slightly can have a strong impact on the safety of service personnel and the safety of equipment.In addition, the mains lighting supply in the elevator (whether correct, PLSCONFM) need be cut off during maintenance, to guarantee leaky not to take place.Though outage is an important operation, but still can omit because of artificial carelessness, thereby become accident potential.
Summary of the invention
The invention provides a kind of solution of the above problems, a kind of latch that can lock elevator and can cut off the elevator power supply automatically is provided.
Technical scheme of the present invention provides a kind of latch that is used for elevator, comprise plug housing and bayonet lock, described plug housing is provided with at least two coaxial through holes, described bayonet lock passes described through hole and is movably arranged on the described plug housing, it is characterized in that: described bayonet lock is provided with the handle perpendicular to described bayonet lock, also be provided with at least two on the described plug housing and can accommodate described handle, and limit the position-limited trough that described handle moves along the axis of described bayonet lock.
Preferably, the latter half of diameter of described bayonet lock is greater than the diameter of the forebody of described bayonet lock, the forebody of described bayonet lock and latter half of between be provided with level and smooth guiding slope, also be provided with a source switch on the described plug housing, described source switch comprises the power knob of a push type, described source switch was closed when described power knob was depressed, and described power knob vertically is resisted against on the described bayonet lock.
Latch of the present invention is arranged on elevator car roof, cooperates with corresponding pin hole, just can fix lift car during the maintenance elevator, eliminates lift car and rocks, and can also cut off the elevator power supply automatically when locking.Have simple in structure, advantage such as function is many.
Description of drawings
Fig. 1 is the structural representation of latch of the present invention.
The specific embodiment
Below the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, latch of the present invention comprises plug housing 10 and bayonet lock 12, plug housing 10 is box-like structures, be provided with on two side panels that (orientation at this place is determined with the viewer of positive alignment pins) is relative wherein a through hole 14 respectively is set, two through holes 14 are coaxial, bayonet lock 12 is provided with the handle 16 perpendicular to bayonet lock 12, two through holes 14 are passed at bayonet lock 12 two ends respectively, the diameter of through hole 14 is bigger slightly than the diameter of bayonet lock 12, bayonet lock 12 just can move along left and right directions like this, and can rotate up and down.On the bayonet lock 12 projection that prevents that bayonet lock 12 from skidding off to the left or to the right can be set.Plug housing 10 front panels are provided with the position-limited trough 18 of at least two top openings, and handle 16 can enter position-limited trough 18 downwards along the opening of position-limited trough 18, and this moment, handle 16 was defined along the mobile of left and right directions.When handle 16 entered the position-limited trough 18 on the left side, bayonet lock 12 stretched out; When handle 16 entered the position-limited trough 18 on the right, bayonet lock 12 was regained.The latter half of diameter of bayonet lock 12 is greater than the diameter of the forebody of bayonet lock 12, the forebody of bayonet lock 12 and latter half of between be provided with level and smooth guiding slope 20.Also be provided with a source switch 22 on the plug housing 10, the power knob 24 of source switch 22 is push types, and power knob 24 is resisted against on the bayonet lock 12 vertically downward, and source switch 22 was closed when power knob 24 was depressed.
Latch of the present invention is installed in the top of lift car (not shown) outside with latch in use, makes it over against car guide rail 26, in the corresponding position of guide rail pin hole 28 is set.When lift car moves to maintenance during the position, the handle 16 of bayonet lock 12 is lifted, promote bayonet lock 12 left, bayonet lock 12 is just in time inserted in the pin hole 28, power knob 24 moves up along guiding slope 20, and power supply disconnects.Put down handle 16, handle 16 enters in the position-limited trough 18 that is arranged on the left side.At this moment, lift car is fixed by latch, can not shake, and power supply disconnects simultaneously, easy access.Maintenance finishes, and upwards makes to withdraw from position-limited trough 18, promotes bayonet lock 12 then to the right, is that bayonet lock 12 withdraws from pin hole.At this moment, power knob 24 moves down along guiding slope 20, connects with the mains again.Make elevator recover normal condition.
Above embodiment only is the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
