Description

Blade and pellet composite construction lock

[technical field]

The utility model relates to field of lockset, particularly a kind of blade and pellet composite construction lock.

[background technology]

Although the lock core of lockset in the market be take, still lock cylinder is as main, and cylinder lock is owing to using history longer, and its security performance also more and more can not meet people's instructions for use.Thereupon, and then occurred that size of key and anti-technical opening ability obtain larger improved blade marble formula lock core.

Wherein, a kind of typical traditional blades cylinder lock adopts the structure of " step pellet " and " T-shaped pellet ".And the design of two kinds of pellets, all at the homonymy of lock core, has taken core space, makes pellet can only be made into step state, step spring length is limited, complex process not only, and differentially cause less close tooth number greatly to reduce.

[utility model content]

In view of this, for overcoming the above-mentioned deficiency of prior art, the utility model provides blade and the pellet composite construction lock that many, the close tooth numbers of a kind of pellet progression are many.

The utility model provides a kind of blade and pellet composite construction lock, comprise tapered end, lock core, round end pellet, tack pellet, marble spring, seal up a door, blade, brake bar and key, described lock core is arranged in described tapered end, and described round end pellet, tack pellet, marble spring and sealing up a door is arranged in the pellet passage of described tapered end inner chamber top successively.Described blade comprises two groups of blades, and described two groups of blades are separately positioned on the both sides of key on described lock core, described brake bar be housed on described lock core with described two groups of blades in groove.

In at least one embodiment, described lock core is roughly cylindrical shape therein, offers respectively main marble hole, two groups of vane holes, key and two groups of brake bar grooves on it.

In at least one embodiment, described key is axially offered along lock core 20 therein.

Therein at least one embodiment, the direction of described main marble hole is for along radially the offering of described lock core, and be positioned at described key directly over.，

In at least one embodiment, the direction of described two groups of vane holes is parallel to the direction of described main marble hole therein, and is located at respectively the both sides of described main marble hole.

Therein at least one embodiment, described brake bar groove is along the both sides that are radially opened in described key of described lock core, and respectively perpendicular to the direction of the described vane hole of correspondence.

The lock core of blade of the present utility model and pellet composite construction lock adopts the structure of " two groups of blades " and " one group of pellet ", and the progression of pellet is increased, and close tooth number increases, and has strengthened technical opening difficulty, and close tooth number can surpass hundred million, the heavy tartar phenomenon of difficult generation.

[specific embodiment]

For understanding better the utility model, below with reference to accompanying drawing and instantiation, the utility model is described in detail.

Refer to Fig. 1 and Fig. 2, it is the topology view of preferred embodiment blade of the present utility model and pellet composite construction lock.This blade and pellet composite construction lock comprises tapered end 10, lock core 20, round end pellet 30, tack pellet 40, marble spring 50, seal up a door 60, blade 70, brake bar 80 and key 90.Lock core 20 is arranged in tapered end 10, and round end pellet 30, tack pellet 40, marble spring 50 and sealing up a door 60 is arranged in the pellet passage (not indicating) of tapered end 10 inner chambers tops successively.Two groups of blades 70 are separately positioned on the both sides of key on lock core 20 (not indicating), the brake bar 80 corresponding with groove on two groups of blades 70 (not indicating) on lock core 20.The detailed structure of all parts below will be described further.

The middle part of tapered end 10 has inner chamber, for lock core, is arranged on wherein.There is certain interval in 20 of the inner chamber of tapered end 10 and lock cores, for lock core 20, in inner chamber, rotates.The top of tapered end 10 is provided with pellet passage, round end pellet 30, tack pellet 40, marble spring 50 and seal up a door and 60 be arranged on successively pellet passage.The tooth contact of round end pellet directly and on key 90.

Incorporated by reference to consulting Fig. 3 and Fig. 4, lock core 20 is roughly cylindrical shape, offers respectively main marble hole 12, vane hole 14, key 16 and brake bar groove 18 on it.Wherein, the direction of key 16 axially offering along lock core 20.The direction of main marble hole 12 is for along radially the offering of key 16 top lock cores 20, and be positioned at key 16 directly over.The direction of two groups of vane holes 14 is the direction that is parallel to described main marble hole 12, and is located at respectively main marble hole 12(and key 16) both sides.Brake bar groove 18 is along the both sides that are radially opened in key of lock core, and perpendicular to the direction of vane hole 14.

When key 90 inserts lock core 20 when interior, if the length of the tooth depth of key 90 and round end pellet 30 matches, the groove of the curved groove of key 90 and blade 70 matches, tack pellet 40 is headed in the pellet passage of tapered end 10, brake bar 80 snaps in respectively in groove corresponding on two groups of blades 70, now lock core 20 can be in the interior rotation of tapered end 10 (as shown in Figure 2), thereby opens lockset.The process that lockset is locked is the inverse process of said process, and therefore not to repeat here.

Blade of the present utility model and this composite construction of pellet lock, the lock core (lock core 20) of employing composite construction, the structure of employing " two groups of blades " (blade 70) and " one group of pellet " (round end pellet 30, tack pellet 40) in lock core.Blade and pellet design are at the offside of lock core, and one-tenth is arranged in parallel, and blade is laid quantity and strengthened, and secret coefficient is strong.

Compare with existing lockset, blade of the present utility model and pellet composite construction are locked to less and have the following advantages:

First, the lock core of blade of the present utility model and pellet composite construction lock adopts the structure of " two groups of blades " and " one group of pellet ", and the progression of pellet is increased, close tooth number increases, strengthened technical opening difficulty, and close tooth number can surpass hundred million, the heavy tartar phenomenon of difficult generation;

Secondly, blade of the present utility model and pellet composite construction lock change one group of traditional three-dimensional T-shaped pellet, and adopt two groups of blades, and blade and pellet design are at the offside of lock core, and design space is reasonable.This blade adopts stainless steel to make, and its shape and manufacture craft are simple, makes precision and is easy to guarantee, intensity is high, and in its application life, anti-technical opening performance further improves.

The above exemplifying embodiment has only been expressed part embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
