Description
Technical field
The utility model relates to a kind of door lock of cold-storage door, is specifically related to a kind of freezer security lock arrangement.
Background technology
Freezer utilizes cooling installation to create suitable humidity and the warehouse of cryogenic conditions, also known as cold store, freezes storehouse or cold storage storehouse, can extend the shelf life of product, to regulate market supply.At present, cold-storage door adopts double-wing door structure usually, and namely two door leafs in left and right pull open along slideway subtend or cut out, and the outside of cold-storage door adopts keeper and padlock to pin, to reach antitheft object.Because door lock is in the outside of cold-storage door, cannot cold-storage door be opened at cool house internal, once carelessness personnel are locked in freezer, life threat will be caused to trapped personnel.In order to prevent personnel to be trapped in freezer, just need can open cold-storage door in freezer, in existing freezer, openable door lock has the structure of this function is not very desirable, and some structures are more complicated, and fault rate is high, and cost is also higher; Although what also have can open cold-storage door in freezer, its theftproof performance decreases.
Utility model content
In order to solve the problem that in existing freezer, openable door latch structure is complicated, cost is high and theftproof is poor, the utility model provides a kind of freezer security lock arrangement, this freezer security lock arrangement pull-up handle in freezer rotates 180 ° can make buckle ring depart from bending body on turning cylinder, and then open cold-storage door, have the advantages that structure is simply exquisite, cost is low and theftproof performance is good.
The technical solution of the utility model is: this freezer security lock arrangement, comprise fixed head, fixed head is fixed with padlock circle and bearing, bearing is hinged with buckle hand, after buckle hand fastens, retainer passes from buckle hand, also include turning cylinder and buckle ring, turning cylinder be arranged on run through a body shaft seat in, visit one end of external body of described turning cylinder is provided with eccentric bending body, described buckle ring one end and buckle palmistry hinged, the other end of buckle ring is enclosed within the bending body of turning cylinder, and after turning cylinder turns an angle, buckle ring can from landing bending body; Shaft seat is fixed on a body by flange, turning cylinder is connected with rocking arm; rocking arm is provided with sleeve and handle; be provided with spring and sliding pin in sleeve; taper knob is outer and be connected with sliding pin at sleeve; flange is provided with locating hole, and sliding pin is positioned at locating hole, the position of locating hole is in buckle ring and bends body and to interlock position.
Described flange is provided with two insurance holes, and two insurance holes are positioned at 45 °, locating hole both sides angle range.
Described flange is provided with withdraws hole, and the angle of withdrawing between hole with locating hole differs 180 °.
Described buckle ring is full-closed structure.
The utility model has following beneficial effect: owing to taking technique scheme, under normal circumstances, sliding pin is positioned at locating hole, and bending body bends to the left, pulls open buckle hand when locking a door, buckle ring is hung on bending body, pressure button spanner, button spanner drives buckle ring to move right, and buckle ring is blocked mutually with bending body, padlock, through buckleing spanner, is now locked in padlock circle by padlock circle.If have trapped personnel in freezer, trapped personnel pull-up handle, spring is compressed, sliding pin pulls out in locating hole, holds handle and rocking arm is rotated 180 °, and turning cylinder is also along with rocking arm rotates, bending body just inclined right lateral bend, now pull a body, buckle ring is deviate from from bending body, and door body is opened.Owing to there being sliding pin to lock, turning cylinder cannot be made to rotate in door external body, theftproof performance is good, and structure is simply exquisite, and cost is low.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By Fig. 1 composition graphs 2, shown in Fig. 3, this freezer security lock arrangement, comprise fixed head 1, fixed head 1 is fixed with padlock circle 2 and bearing 3, bearing 3 is hinged with buckle hand 4, buckle hand 4 fastens rear retainer 2 and passes from buckle hand 4, also include turning cylinder 5 and buckle ring 6, turning cylinder 5 is arranged on and runs through in the shaft seat 8 of a body 7, visit one end of body 7 outside of described turning cylinder 5 is provided with eccentric bending body 9, described buckle ring 6 one end and buckle hand 4 are hinged, the other end of buckle ring 6 is enclosed within the bending body 9 of turning cylinder 5, after turning cylinder 5 turns an angle, buckle ring 6 can from landing bending body 9, shaft seat 8 is fixed on a body 7 by flange 10, turning cylinder 5 is connected with rocking arm 11, rocking arm 11 is provided with sleeve 12 and handle 13, be provided with spring 14 and sliding pin 15 in sleeve 12, it is outer and be connected with sliding pin 15 that handle 13 is enclosed within sleeve 12, flange 10 is provided with locating hole 16, and sliding pin 15 is positioned at locating hole 16, the position of locating hole 16 is in buckle ring 6 and bends body 9 and to interlock position.Owing to taking technique scheme, under normal circumstances, sliding pin 15 is positioned at locating hole 16, and bending body 9 bends to the left, pulls open buckle hand 4 when locking a door, buckle ring 6 is hung on bending body 9, pressure button spanner 4, button spanner 4 drives buckle ring 6 to move right, buckle ring 6 and bending body 9 phase card, padlock, through buckleing spanner 4, is now locked in padlock circle 2 by padlock circle 2.If have trapped personnel in freezer, trapped personnel pull-up handle 13, spring 14 is compressed, and sliding pin 15 is from pull-out in locating hole 16, hold handle 13 and rocking arm 11 is rotated 180 °, turning cylinder 5 also rotates along with rocking arm 11, and bending body 9 just inclined right lateral bend, now pulls a body, buckle ring 6 is deviate from from bending body 9, door body is opened, and the bias design of bending body 9 can make to produce gap between buckle ring 6 and bending body 9, is beneficial to buckle ring 6 and departs from bending body 9.Owing to there being sliding pin 15 to lock, turning cylinder 5 cannot be made to rotate in door external body, theftproof performance is good, and structure is simply exquisite, and cost is low.
Described flange 10 is provided with insurance hole 17, two insurance 17, two, holes and is positioned at 45 °, locating hole 16 both sides angle range.This structure mainly prevents defalcator, if deliberately pull out sliding pin 15 when locking a door, and deflect a little to locating hole 16 both sides, now can rotate at outside turning cylinder 5, no matter turning cylinder 5 rotates sliding pin 15 to which direction all can drop in insurance hole 17, the corner of turning cylinder 5 can not more than 45 °, and buckle ring 6 still cannot be deviate from from bending body 9, has good anti-theft effect.
Described flange 10 is provided with withdraws hole 18, and the angle of withdrawing between hole 18 with locating hole 16 differs 180 °.After turning cylinder 5 is rotated 180 ° by the trapped personnel in freezer, sliding pin 15 falls into be withdrawn in hole 18, and conveniently pull the door open body.
Described buckle ring 6 is full-closed structure.Buckle ring 6 is bent by reinforcing bar and forms, the joint welding of buckle ring 6.Main raising theftproof performance, avoids thief buckle ring 6 to be pried open, and makes buckle ring 6 depart from buckle hand.
