Abstract
The utility model relates to a snake-shaped crossed no-spring vane lock and a key thereof. The utility model is characterized in that the utility model adopts a lock core without springs. The utility model is provided with crossed vanes in two directions. The vanes in the two directions are arranged at intervals. The adjacent vanes are pasted, and have no space distance. The length of all vanes is equal, and is equal to the outer diameter of a lock core body. Key holes have equal length and different positions on the vanes in the same direction. The key holes in the vanes in the same direction stays in a state of opening to form an upward snake-shaped track with the same width along an axis. The outer ends of the vanes are inserted in an axial hole at the position corresponding to the lock core body. A lock head body matched with the lock core body is provided with a positioning slot at a corresponding position. The utility model is used for theft prevention, and has high reliability.
Description
Technical field:
The utility model relates to lockset and key, the blade lock ﹠ key of more specifically saying so.
Background technology:
At present, cylinder lock on the domestic and international market and blade lock all have pellet shot from a slingshot distance and blade pitch basically, under the active force of spring, finish the unlatching and the locking of lockset, because certain distance (the minimum 3mm of being of cylinder lock, the minimum 2mm of being of blade lock) is arranged between each pellet shot from a slingshot or between the blade, this just provides opportunity for the thief and the master-hand that unblanks, as long as they with finer wire and some simple tools, rely on feel just can choose unlocking tool.In addition because the existence of blade pitch, make its size of key just the different tooth numbers of key be restricted, the reliability of lock is affected.
Summary of the invention:
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of snakelike cross spring-free blade lock and key that can greatly improve the function of lock being provided.
The technical scheme that the utility model technical solution problem is adopted is:
The design feature of snakelike cross spring-free blade lock is to adopt no spring lock core in the utility model, described no spring lock core has the blade of the both direction that is cross, blade on the both direction is provided with at interval, adjacent blades pastes distance continuously mutually, each length of blade equates and equates with the lock core body external diameter, the key hole has equal lengths and different positions on each blade of same direction, under opening, constitute vertically wide serpentine track with key hole in described each blade that is on the same direction, the blade outer end is inserted in the vane hole of lock core body correspondence position, the locating slot that has correspondence position interior week of the tapered end that is equipped with lock core body.
The design feature of matching used key is corresponding to being longitudinal blade and the cross blade that cross is provided with in the lock core body in the utility model, two groups of tartars are set being cross on the key, corresponding to described wide serpentine track, what coincide with it is vertically wide snakelike tartar on the key, comprises vertical tartar and horizontal tartar.
The utility model is under the active force that key inserts, and blade moves radially in lock core body along snakelike tooth on the key.When the formed serpentine track of key tooth and the central key hole of blade matched, all income was in lock core body at the blade both ends, and can unblank this moment.When key and blade were not complementary, lock core body was stretched out in the end of blade, and is inserted in the locating slot of tapered end, and can not open lockset this moment.When normal no key inserted, blade relies on deadweight and disorder will locking mutually.Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model is not found with regard to there being some blades to be hidden in the back of other blades like this owing to paste mutually not at interval between each blade, the sensation even if the master-hand that unblanks also has no way of.
2, the utility model since between blade continuously every, its number of blade can reach 10 to 30, so the different tooth numbers of its key from 100,000 times to hundreds of thousands.
3, the utility model can be widely used in each antitheft occasion.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the blade construction schematic diagram of the utility model key and cooperation.
Fig. 3 is the utility model tapered end structural representation.
Number in the figure: 1 lock core body, 2 longitudinal blades, 3 cross blades, 4 keys, 5 vertical tartars, 6 locating slots, 7 vane holes, 8 tapered ends, 9 horizontal tartars.
The specific embodiment:
Referring to Fig. 1, Fig. 2 and Fig. 3, lock in the present embodiment adopts no spring lock core, no spring lock core has the blade of the both direction that is cross, be longitudinal blade 2 and cross blade 3, blade on the both direction is provided with at interval, adjacent blades pastes distance continuously mutually, each length of blade equates and equates with the external diameter of lock core body 1, the key hole has equal lengths and different positions on each blade of same direction, under opening, constitute vertically wide serpentine track to be in key hole in each blade on the same direction, the blade outer end is inserted in the vane hole 7 of lock core body 1 correspondence position, the locating slot that has correspondence position interior week 6 (shown in Figure 3) of the tapered end 8 that is equipped with lock core body 1.
Shown in Figure 2, on the key 4 of corresponding configuration, corresponding to the blade on the both direction that is the cross setting, be cross two groups of tartars are set, comprise vertical tartar 5 and horizontal tartar 9, corresponding to the wide serpentine track that is made of the key hole on the blade, what coincide with it is vertically wide snakelike tooth on the key 4.
When key 4 inserted, each blade moved radially in lock core body 1 along snakelike wide tooth on the key.When the formed serpentine track of key tooth flower and the central key hole of blade matched, all income was in lock core body 1 at the blade both ends, and can unblank this moment.When key and blade were not complementary, lock core body 1 was stretched out in the end of blade, and was inserted in the locating slots 6 in week in the tapered end 8, and can not open lockset this moment.When normal no key inserted, blade relies on deadweight and disorder will locking mutually.
