Description

Simple door lock

Technical Field

The utility model relates to a lock technical field, more specifically say, it relates to a simple-assembling formula lock.

Background

The door lock is generally assembled with a door body for locking or unlocking the door, and includes a locking mechanism portion and a door handle portion installed outside the door. After the door lock is closed, the locking bolt in the locking mechanism is driven to stretch and retract by the rotation of the door handle or the rotation of the safety button, so that the door lock is opened or closed. When the existing door lock is opened or closed by a lock, a plurality of parts are matched to realize the existing door lock, so that the structure of the whole door lock is complex and not compact, the assembly efficiency of the door lock is influenced, and the production cost of the door lock is also improved. Therefore, the simple door lock is simple in structure, high in working quality and easy to assemble.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a simple structure, simple operation's simple-structured formula lock.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a simple-mounted formula lock, includes interior handle and locking mechanism, interior handle includes interior handle casing, is equipped with horizontal conical gear in interior handle casing, the meshing has vertical conical gear on the horizontal conical gear, the cooperation has the safety button on the vertical conical gear, outside the one end of safety button extended to interior handle casing, through rotatory safety button, drive vertical conical gear and rotate, drive horizontal conical gear by vertical conical gear and rotate, horizontal conical gear is connected with locking mechanism, and the rotation through horizontal conical gear drives locking mechanism and moves the operation, makes the lock realize opening or the action of closing.

The utility model discloses further set up to: the safety button comprises a rotating block and a rotating sleeve, the rotating sleeve is inserted and fixed in the longitudinal bevel gear, and the rotating block extends out of the door inner handle shell.

The utility model discloses further set up to: a fixed support is arranged in the inner door handle shell, and the part of the longitudinal bevel gear connected with the rotary sleeve is clamped in the fixed support for assembly.

Through adopting above-mentioned technical scheme, improve the lock and go up the inner structure of door inner handle and the cooperation structure of insurance button, make the structure of whole lock simple more compact, open or close often in the operation, through the cooperation of vertical conical gear and horizontal conical gear, drive the locking mechanical system operation to the realization is to opening or closing of lock, the simple operation does benefit to the operating mass with rated load that promotes whole tool to lock.

1. An inner door handle housing; 2. a transverse bevel gear; 3. a longitudinal bevel gear; 4. a safety button; 5. rotating the block; 6. rotating the sleeve; 7. and fixing the bracket.

Detailed Description

The embodiment of the present invention is further explained with reference to fig. 3. The structures, proportions, and dimensions shown in the drawings and described in the specification are for illustrative purposes only and are not intended to limit the scope of the present invention, which is defined by the claims, but rather the structures, proportions, and dimensions shown in the drawings and described in the specification are for illustrative purposes only and are not intended to limit the scope of the present invention. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.

The utility model provides a simple-mounted formula lock, includes interior handle and locking mechanism, interior handle includes interior handle casing 1, is equipped with horizontal conical gear 2 in interior handle casing 1, the meshing has vertical conical gear 3 on the horizontal conical gear 2, the cooperation has safety button 4 on the vertical conical gear 3, outside the one end of safety button 4 extended to interior handle casing 1, through rotatory safety button 4, drives vertical conical gear 3 and rotates, drives horizontal conical gear 2 by vertical conical gear 3 and rotates, horizontal conical gear 2 is connected with locking mechanism, drives locking mechanism operation through the rotation of horizontal conical gear 2, makes the lock realize opening or the action of closing. The safety button 4 comprises a rotating block 5 and a rotating sleeve 6, the rotating sleeve 6 is inserted and fixed in the longitudinal bevel gear 3, the rotating block 5 extends out of the inner door handle shell 1, a fixing support 7 is arranged in the inner door handle shell 1, and the part, connected with the rotating sleeve 6, of the longitudinal bevel gear 3 is clamped in the fixing support 7 for assembly.

During operation, the transverse conical gear 2 is driven to rotate by the longitudinal conical gear 3 through the rotation operation of the safety button 4, so that the locking mechanism is driven to move, the bolt is driven to contract, and the purpose of opening or closing the lockset is achieved. The lock body after the improvement, inner structure is simple, and the simple operation does benefit to and promotes work efficiency, can reduction in production cost again, promotes the operating mass with rated load of tool to lock.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
