Abstract

The invention discloses a winding-unwinding type key cylinder, and belongs to the technical field of office supplies. The winding-unwinding type key cylinder is composed of a key cylinder body (1), a key shaft (2), end covers (3), spiral springs (4), key rings (5) and key ropes (6). The end covers (3) with shaft holes in the centers are arranged at the two ends of the key cylinder body (1) respectively, and the key shaft (2) is installed in the shaft holes. The inner ends of the spiral springs (4) are fixed to the key shaft (2), and the outer ends of the spiral springs (4) are fixed to the inner wall of the key cylinder. The key ropes (6) are wound around the key shaft (2) and extend outwards to penetrate out of holes in the key cylinder body (1), the key rings (5) are arranged at the tail ends of the key ropes (6), and keys can be bunched to the key rings (5). When the key ropes (6) are pulled out, the spiral springs (4) are tightly wound; when the key ropes (6) are released, the spiral springs (4) are expanded through elastic force of the spiral springs (4), and the key shaft (2) is rotated to pull the key ropes (6) back. The sequentially-arranged keys are bunched to the key rings (5) at the ends of the key ropes (6). The required keys are pulled out and automatically withdrawn after being released. At ordinary times, the set of related keys are simply gathered together in order, and the required keys are pulled out in use. Storage, identification and use are convenient, and the winding-unwinding type key cylinder is used for storing a set of related keys.

Description

Extendible key cylinder

Technical field office appliance.

One people such as reference room management person, warehouse keeper of background technology office building manages tens 20 roomsBetween, even more, tens keys, put down a pile, and the used time now looks for, trouble inconvenience. At present improvement is doneMethod is: with a tabular ring, the uniform one group of key of week circle, is commonly called as key ring. In use, find: the one, phaseAdjacent key hook; The 2nd, for the door of hole formula door wall, to lock a door while opening the door, a key ring wall that collides with, hinders and turnsMoving.

The technical problem that summary of the invention extendible key cylinder will solve is: keen-witted and capable a group key intensive receiptsHold together together, just receive and just get just and use.

The technical scheme adopting is: key is connected in respectively the rope end of crispaturaing in cylinder, and key is exposed at outside cylinder,Used time connects the pull-out of key band rope, connects at ordinary times rope band key and retracts.

Extendible key cylinder (Fig. 1) by key cylinder 1, key axle 2, end cap 3, spiral spring 4, key ring 5,Key rope 6 forms. There are the end cap 3 of axis hole, the in-built key axle 2 of axis hole in key cylinder 1 each You Yige center, two ends.Spiral spring 4 inner end heads are fixed on key axle 2; External end head is fixed on key cylinder 1 inwall. Key rope 6 is wound aroundOn key 2, overhangingly pass by the hole on key cylinder 1; End has key ring 5, can go here and there key.When key rope 6 pulls out, spiral spring 4 is rolled tightly; Unclamp key rope 6, spiral spring 4, by self elastic force spreading, rotatesKey axle 2, retracts key rope 6.

When use, on the key ring 5 of rule key rope 6 terminations, on string, arrange orderly key. UseWhich is which handle of pull-out, and one holds the hand-held key of key cylinder 1, opens the door. After opening the door, loose one's grip, key rope 6 quiltsSpiral spring 4 is regained.

The beneficial effect of extendible key cylinder is: one group of intensive orderly gathering of associated key at ordinary times together; Used timePull out desired one. Be convenient to harvesting, be convenient to identification, easy to use.

Brief description of the drawings Fig. 1 shows extendible key cylinder structural representation.

In figure: 1---key cylinder; 2---key axle; 3---end cap; 4---spiral spring; 5---key ring;6---key rope.

Detailed description of the invention

Two half of the plastic injection-moulded one-tenth opposite opened of key cylinder 1 use. Half uniform one group of semicircle orifice in one side, two halfCylinder forms a circular hole after merging, and key rope 6 therefrom passes. There are mark district, Ke Yibiao in one group of circular hole sideNote relevant information, as room number. Two semicircular cylinders bind round into a whole cylinder with end cap 3.

Plastic injection-moulded the forming of key axle 2 use. The axle that centre twines key rope 6 is dry thick; The axle of two ends and end cap 3The spindle nose that hole coordinates is thin.

Plastic injection-moulded the forming of end cap 3 use, is vegetable dish shape; The lid limit of periphery projection is tightly two half key cylinders 1Wale. The axis hole place thickening at center is protruding closes, to steadily support key axle 2.

Key rope 6 is nylon ropes, and end is connected with reversion formula key ring 5 with heat seal circle.
