Abstract

The utility model belongs to the field of construction hoists and particularly relates to an automatic resetting door lock device. The automatic resetting door lock device comprises a lock seat and a door hook, wherein a supporting seat used for mounting the door hook is arranged on the lock seat, the door hook is installed on the supporting seat through a hinge shaft, the door hook can rotate around the hinge shaft, a torsion spring is also sleeved on the hinge shaft, the torsion spring is provided with a first stretching pin and a second stretching pin, and the first stretching pin and the second stretching pin are respectively pressed on the lock seat and the door hook. Since the torsion spring is sleeved on the hinge shaft connected with the door hook and the supporting seat in the utility model, the door hook automatically resets through the torsion of the torsion spring, and since the torsion spring is sleeved on the hinge shaft, the torsion spring is unlikely to drop, thereby ensuring the automatic resetting reliability of the door hook.

Description

A kind of door lock assembly that automatically resets

Technical field

The utility model belongs to construction elevator field, particularly a kind of door lock assembly that automatically resets.

Background technology

In today of the high speed development of national economy, the building machineries such as construction elevator start bringing into play huge effect at increasing building field, especially for large-engineering, and highrise building place, it is particularly important that the use of construction elevator seems, it can greatly be boosted productivity and economize labor time.Therefore, people are also more and more higher to the composite request of the various aspects such as the performance of hoist, efficiency, carrying capacity, energy-conservation, maintenance.

Construction elevator is (built on stilts) when operation, the door body of the outer cage on ground requires to close, prevent that stranger from entering outer cage and causing security incident, the outer cage door lock assembly of construction elevator arranges compression spring between lock and gate stop at present, utilizes compression spring to reset, when construction elevator drops to ground, the iron that touches of construction elevator is pushed down gate stop afterbody, make gate stop separated with outer cage door body, now compression spring is compressed, and door body can be opened; Construction elevator built on stilts, gate stop resets and hooks a body in compression spring effect, causes a body not open.Because compression spring is by Repeated Compression with reset and easily to lose efficacy, and compression spring easily departs between lock and gate stop, causes gate stop not automatically reset a door body for outer cage is hooked, and causes a body to fail pinning, to people, has been with potential safety hazard.

Summary of the invention

The purpose of this utility model is to propose a kind of door lock assembly that automatically resets reliably that automatically resets for above-mentioned problem.

In order to achieve the above object, the technical scheme that the utility model is taked: a kind of door lock assembly that automatically resets, comprise lock and gate stop, lock is provided with for the supporting seat of gate stop is installed, gate stop is installed on supporting seat by jointed shaft, gate stop can rotate around jointed shaft, on described jointed shaft, be also set with torsion spring, torsion spring is provided with first and second and stretches out pin, and first and second stretches out pin and is pressed in respectively on lock and gate stop, because torsion spring is to be enclosed within on jointed shaft, torsion spring difficult drop-off, has guaranteed the automatically reset reliability of gate stop.

In order to improve the elastic force of torsion spring, guarantee the reliability resetting, above-mentioned first stretches out pin is positioned at torsion spring two ends, second stretches out pin stretches out between pin at first of torsion spring two ends, and gate stop is sandwiched in second and stretches out between pin, and the second afterbody that stretches out pin is pressed in the back side of gate stop, the position that pin is pressed in respectively corresponding gate stop both sides on lock is stretched out at first of torsion spring two ends, the torsion spring setting of this programme, has not only improved the torsion of torsion spring, has also further guaranteed torsion spring difficult drop-off.

In order to guarantee that in the process on construction elevator landing ground, touching iron can be smoothly gate stop tilting, the afterbody of above-mentioned gate stop is provided with arcwall face.

On jointed shaft owing to being connected with supporting seat at gate stop of the present utility model, be set with torsion spring, utilize the torsion of torsion spring to realize automatically reseting of gate stop, because torsion spring is to be sleeved on jointed shaft, so torsion spring difficult drop-off, guaranteed the automatically reset reliability of gate stop, the torsion spring that same material is made and compression spring, the longer service life of torsion spring, is difficult for losing efficacy.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail.Wherein accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent; For better explanation the following example, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing some known features and explanation thereof may to omit be understandable.

Embodiment

The structure of the door lock assembly that automatically resets of the present utility model as shown in Figure 1, comprise lock 1, gate stop 2 and torsion spring 4, described lock 1 is provided with supporting seat 11, gate stop 2 is installed on supporting seat 11 by jointed shaft 3, gate stop 2 can rotate around jointed shaft 3, torsion spring 4 is sleeved on jointed shaft 3, the two ends of described torsion spring 4 are respectively equipped with first and stretch out pin 41, between the two ends of torsion spring 4, be provided with second and stretch out pin 42, the position that pin 41 is pressed in respectively corresponding gate stop 2 both sides on lock 1 is stretched out at first of the two ends of torsion spring 4, second stretches out the both sides that pin 42 is clipped in gate stop 2, and the second afterbody that stretches out pin 42 is pressed in the back side 21 of gate stop 2, gate stop 2 is 21 rotations to the back side, need to overcome the torsion of torsion spring 4.

The afterbody of above-mentioned gate stop 2 is provided with arcwall face 22, in construction elevator landing surface process, touches the arcwall face 22 of iron 5 extruding gate stop 2 afterbodys, can make its front end depart from door body 7 by very smooth tilting gate stop 2.

When the utility model is installed, lock 1 is fixed on to the top of doorframe 6, under door body 7 closed conditions, the top that gate stop 2 front ends can hook a body 7, as shown in Figure 2.In construction elevator landing surface process, hoist touch the arcwall face 22 that iron 5 presses down gate stop 2 afterbodys, cause gate stop 2,3 front ends to depart from the top of door bodies 7, at hoist built on stilts not, touch iron 5 and push down the afterbody of gate stop 2 always, as shown in Figure 4,5, door body 7 can be opened at any time; When hoist built on stilts, the iron 5 that touches of hoist departs from gate stop 2, and gate stop 2 automatically resets under the twisting force of torsion spring 4, and the front end of gate stop 2 hooks the top of a body 7, and door body 7 can not be opened, and guarantees construction safety.

The corresponding same or analogous parts of same or analogous label in above-described embodiment; In accompanying drawing, describe position relationship for only for exemplary illustration, can not be interpreted as the restriction to this patent.

Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.All any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in the protection domain of the utility model claim.
