Abstract

The utility model discloses a top-opening padlock. The top-opening padlock comprises a shell, a lock cylinder and a lock hook, wherein a vertical lock cylinder hole is formed in the shell; the lock cylinder is placed in the lock cylinder hole to moveably match; a plurality of thin slots matched with a blade of the lock cylinder are formed on the inner wall of the lock cylinder hole; a stroke limit structure is arranged between the lock cylinder and the shell; the diameter of an outlet at the upper end of the lock cylinder hole corresponds to the lock hook; one end of the lock hook penetrates into the lock cylinder hole from the upside and is then fixedly connected with the lock cylinder; and a return spring is positioned in the lock cylinder hole over the lock cylinder to form a sealing sheet-free shell sealed structure. The top-opening padlock has a reasonable structure; the shell is sealed without a sealing sheet or a sealing lid; the return spring is enclosed in the shell; the blade and the lock cylinder are high in compactness and are convenient to assemble; the product is reliably used and is not easy to damage when falling onto the ground; the quality is improved; the parts are reduced; and the material cost and the production assembly cost are reduced.

Description

The top-opening type padlock

Technical field: the utility model relates to the padlock of a kind of padlock, particularly top-opening type.

Background technology: all be to insert key twisting lock core when traditional padlock is opened, will latch hook one end eject and hang up again after forming free end, then the free end of latch hook will be aimed at when locking to press down again after the housing respective aperture and be pressed into.Latch hook can't eject when this padlock occurred opening after use a period of time easily, must pull.Then be not easy aligned position when locking, and will very firmly press down just and can be pressed into inconvenient operation.

The top-opening type padlock has been arranged now, for example the patent No. 95202921.9 disclosed pellet shot from a slingshot top locks are gone up the top smoothly behind the insertion key and can be made an end of latch hook shift out the formation free end, and key then latch hook is rotated thereupon, can move down pinning automatically when arriving latched position, operation is very easy.But, the lock core marble of existing top-opening type padlock and spring must mounting arrangements at the sidewall of housing, also be that the sidewall of housing need bore a plurality of through holes and seals with mounting.And, also must be provided with capping on the housing of latch hook and lock core junction, push down back-moving spring.In the reality, capping or mounting may come off from housing because of touching etc., and particularly capping is subjected to spring and the last top power effect when unblanking, and easier coming off causes padlock to use, and reliability is not high.Simultaneously, want process and assemble mounting and capping also to cause cost to rise in the production.

Summary of the invention: at the deficiencies in the prior art, it is a kind of rational in infrastructure that the utility model provides, service-strong top-opening type padlock.

The utility model comprises housing, lock core and latch hook, is provided with vertical lock core hole in the housing, and lock core places lock core hole move to cooperate, and the lock core hole inwall is provided with the stria that the blade of many and lock core cooperates, and is provided with the stroke limit structure between lock core and the housing; The upper end outlet diameter of this lock core hole and latch hook correspondence, an end of latch hook penetrate the lock core hole and fixedly connected with lock core from the top, back-moving spring then is arranged in the lock core hole of lock core top, constitutes no mounting sandwich type element enclosed construction.

Of the present utility model rational in infrastructure, housings close need not mounting or capping, back-moving spring is enclosed in the housing, the blade lock core compactedness is good, and is easy to assembly, and the use of product is very reliable, touch land etc. not fragile, quality improves, and has reduced the number of spare parts of padlock, has reduced material and production assembly cost.

Further specify the utility model below in conjunction with drawings and Examples.

Description of drawings: Fig. 1 is the main structure schematic diagram of embodiment.

Fig. 2 is the unlocking condition schematic diagram of Fig. 1.

The specific embodiment

Embodiment: as shown in Figure 1, be provided with vertical lock core hole 3 in the housing 1, lock core 2 places lock core hole 3 to move to cooperate, and lock core hole 3 inwalls are provided with the stria 5 that the blade 4 of many and lock core 2 cooperates, and are provided with the stroke limit structure between lock core 2 and the housing 1.The upper end outlet diameter of this lock core hole 3 and latch hook 6 correspondences, an end of latch hook 6 penetrate the lock core hole 3 and fixedly connected with lock core 2 from the top, 7 of back-moving springs are arranged in the lock core hole 3 of lock core 2 tops, constitute no mounting sandwich type element enclosed construction.Stroke limit structure Design form can have multi-form, lock core 2 outer walls in the present embodiment are provided with cannelure 8, alignment pin 9 inner ends and the cannelure 8 that penetrate housing 1 sidewall cooperate, and the connection of cannelure 8 tops is provided with one section vertical stroke groove 10, constitute the stroke limit structure, this form process and assemble is all fairly simple rationally, further reduces cost.

When unblanking to use, as shown in Figure 2, the key insertion makes the blade 4 of lock core 2 and the stria 5 of lock core hole 3 inwalls break away from cooperation, go up the top then smoothly, along the cooperation path of stroke groove 10 and alignment pin 9 with lock core 2 together with moving on the latch hook 6, key again, lock core 2 rotates along cannelure 8 together with latch hook 6.When latch hook 6 is rotated back into original locked position, also be that lock core 2 forwards the position that stroke groove 10 is aimed at alignment pin 9 inner ends to, under back-moving spring 7 effects, lock core 2 moves down automatically together with latch hook 6, extracts the locking states that key promptly returns to Fig. 1, operates easy and convenient.
