Abstract

The utility model relates to a blade lock, which is mainly composed of a lock body, a lock core, blades, a side-arc key, etc. Because the blades are driven by the side-arc key, and a blade spring is not adopted, a blade groove of the lock core can be filled up by the blades so as to increase the number of the blades and increase the size of key. The blade lock is matched on various locksets to use.

Description

Blade locking head

The utility model relates to a kind of tapered end, particularly a kind of blade locking head.

Blade locking head is subjected to the influence of the shared locus of leaf spring, and blade must be separated by its lock core, and the sheet number that blade is installed on the certain axial length of its lock core is limited, and its size of key is lower, and when difference exchange number was two, its size of key was lower.In order to improve size of key, the common practice is to increase the lock core axial length in the hope of many dress blades and spring thereof, but also brought simultaneously to make inconvenience is installed.

The purpose of this utility model provides a kind of and uses the Arc-key driven vane, does not adopt the blade locking head of leaf spring, and it can improve size of key under the prerequisite that does not increase the lock core axial length.

The purpose of this utility model is achieved in that the utility model is a blade construction, mainly is made up of tapered end, lock core, blade and Arc-key.Have rectangular blade groove on the lock core, fill the blade of contact parallel to each other in the blade groove.Be matched in clearance between the internal orifice of blade and Arc-key middle part, the both sides, middle part of Arc-key are curved, only use the Arc-key driven vane.(not adopting leaf spring)

Good effect of the present utility model: because it does not adopt leaf spring, be not subjected to need the take up space influence of position of leaf spring, thereby blade can contact with each other, from face can be under the prerequisite that does not increase the lock core axial length many dress blades, so can improve size of key.

The explanation of accompanying drawing drawing:

Fig. 1. blade locking head assembling schematic diagram Fig. 2. the lock core front view

Fig. 3. one of blade front view Fig. 4. two of blade front view

Fig. 5. A-A shown in Figure 1 is to generalized section Fig. 6. three of blade front view

Fig. 7. four Fig. 8 of blade front view. five of blade front view

Among the figure: 1. Arc-key; 2. lock core; 3. tapered end; 4. blade; 5. tapered end blade groove;

6. middle part; 7. circlip; 8. spoon passes mouth; 9. blade groove; 10. internal orifice.

Embodiment 1: as shown in the figure, the person is as good as its tapered end of the utility model (3) with being equipped with the leaf spring.Its lock core (2) has rectangular blade groove (9).Its blade (4) is regardless of differential punching press, the sharp edge chamfering, and shape such as Fig. 3 are shown in Figure 4, select for use wherein a kind of or the mixing use according to requirements such as technologies.The internal orifice (10) of blade (4) is matched in clearance with the middle part (6) of Arc-key (1).(6) cross section, middle part of Arc-key (1) and the internal orifice (10) of blade shown in Figure 3 (4) is corresponding, two side millings are curved, the system method of milling can be consulted Chinese patent notice of authorization CN2289021Y, the manual in August 26 1998 notice of authorization day.

During assembling, blade (4) is arranged in parallel, the flatness of blade (4) is adjusted in conjunction with the internal orifice (10) of blade (4) and the fit clearance at the middle part (6) of Arc-key (1) in blade groove (9) back of filling lock core (2), Arc-key (1) can be plugged flexibly and blade (4) is not scattered because of the self gravitation factor under contact engaging and separating force effect commonly used.After inserting good Arc-key (1), worn blade (4) two ends surplus, the tapered end of packing into (3) can use.

During use, insert Arc-key (1), tapered end is promptly opened; Extract Arc-key (1), tapered end is a locking.Blade (4) blocks or discharges middle part (6) the both sides driving of lock core (2) motion by Arc-key (1), need not to use leaf spring.Eliminate leaf spring and need take up space after the influence of position, the sheet number that can adorn blade (4) on the same axial length of lock core reaches more than 2 times more, and size of key improves thereupon, and when difference exchange number was two, its advantage was more obvious.

Embodiment 2: as shown in the figure, internal orifice (10) shape of blade (4) is pressed Fig. 6 to 8 and is made, (6) cross section, middle part of Arc-key (1) is corresponding with the internal orifice (10) of blade shown in Figure 6 (4), selects wherein a kind of or mixing use of blade shown in Fig. 6 to 8 (4) during assembling for use.Surplus with embodiment 1.The Arc-key of present embodiment (1) establishes one's own system, and uses for important events.
