Abstract
The utility model discloses a locking body, which comprises a buckle, a lining plate and an oblique tongue, wherein the lining plate is arranged on the front side of the locking body, and the oblique tongue is arranged on the lining plate; and the locking body is characterized in that the bearing is arranged on the oblique tongue; a shaft hole is formed in the direction in which the oblique tongue is parallel to the inclined surface of the oblique tongue; a rotating shaft on the bearing is arranged in the shaft hole; and a rolling cylindrical surface of the bearing is hinged than the inclined surface of the oblique tongue. The bearing is arranged on the oblique tongue of the locking body, the oblique tongue is contacted with the buckle through the rolling cylindrical surface on the bearing, the oblique tongue and the buckle are in rolling friction; the friction between the oblique tongue and the buckle is rolling friction between the metals, and the friction force of the oblique tongue can be reduced due to the rolling friction, so that the contact surface between the oblique tongue and the buckle is hardly damaged; and therefore, the service life of the locking body is prolonged, and the closing force is reduced.
Description
Technical field
The utility model relates to a kind of lock body, and specifically a kind of tiltedly tongue and buckle frictional force of reducing at closing time improves the lock body lock body in application life.
Background technology
The structure of common lock generally comprises lock body, tapered end and key, and the oblique tongue and the square tongue of rotation and locking effect arranged on the lock body, and lock core is arranged in the tapered end, is connected with the sword iron of driver blade on the lock core, and sword iron inserts in the knob on the lock body.When key inserts in the lock core, twist lock core, can drive knob through the sword iron transmission, thereby drive dead bolt.Be sliding friction between oblique tongue on the existing lock body and the buckle, friction between the two is the sliding friction between metal and the metal, along with the passing of the fraction time contact surface between oblique tongue and the buckle that can wear and tear, has potential safety hazard after long-term the use.
The utility model content
The purpose of the utility model provides a kind of oblique tongue frictional force that reduces, and improves the lock body lock body in application life.
The purpose of the utility model realizes through following technical scheme.
A kind of lock body comprises buckle, liner plate and oblique tongue, and liner plate is installed in the lock body front side, and tiltedly tongue is installed on the liner plate, it is characterized in that: on the said oblique tongue bearing is installed.
Be provided with axis hole with oblique parallel direction place, tongue inclined-plane in the said oblique tongue, the rotating shaft on the bearing is installed in the axis hole.
Rolling circle cylinder on the said bearing is higher than the inclined-plane on the oblique tongue.
The utility model compared with prior art has the following advantages:
On the oblique tongue of the utility model lock body bearing is installed; Tiltedly tongue contacts with buckle through the rolling circle cylinder on the bearing; Tiltedly be rolling friction between tongue and the buckle, friction between the two is the rolling friction between metal and the metal, and rolling friction can reduce oblique tongue frictional force; Make the contact surface between oblique tongue and the buckle not fragile, thereby improve the application life of lock body.
Description of drawings
Fig. 1 is the front view of the utility model lock body;
Fig. 2 is the lateral view of the utility model lock body.
Fig. 3 is the utility model buckle structure sketch map.
The specific embodiment
Below in conjunction with accompanying drawing the utility model lock body is described in further detail.
Like Fig. 1, Fig. 2 and shown in Figure 3, the described lock body of the utility model comprises buckle 1, liner plate 2 and oblique tongue 3, and liner plate is installed in the lock body front side, and tiltedly tongue is installed on the liner plate, tiltedly on the tongue bearing 4 is installed.Tiltedly be provided with axis hole with oblique parallel direction place, tongue inclined-plane in the tongue, the rotating shaft on the bearing is installed in the axis hole.Rolling circle cylinder on the bearing is higher than the inclined-plane on the oblique tongue.On the oblique tongue of the utility model lock body bearing is installed; Tiltedly tongue contacts with buckle through the rolling circle cylinder on the bearing; Tiltedly be rolling friction between tongue and the buckle, friction between the two is the rolling friction between metal and the metal, and rolling friction can reduce oblique tongue frictional force; Make the contact surface between oblique tongue and the buckle not fragile, thereby improve the application life of lock body.
Claims (3)
