Door lock lock reversing adjustment structure

The present invention relates to a door lock structure, and more particularly to a lock ring reversing adjustment structure of a door lock.

According to the general locking of the door panel, the door frame is extended by the locking tongue. Since it is assembled to conform to the left side opening and the right side opening of the door panel, the door lock is designed with an adjustable locking tongue direction structure, and a conventional door locking structure. For example, the "locking tongue reversing adjustment structure of the door lock" approved by the Department of Economics on October 21, 101, the door lock includes a through opening and an assembly space, and the assembly space is The utility model has a brake seat and a penetration portion, and the lock tongue reversing adjustment structure comprises: a lock tongue protruding from the outside of the door lock, and the lock tongue has an extension portion extending the assembly space of the entry lock And a lateral displacement and rotation actuation; a limiting block disposed at one end of the extension of the locking tongue; a dial control disposed in the assembly space and correspondingly disposed on the side of the extension of the tongue The stop surface of the dial is configured to abut the limit block, and one side of the dial is disposed with a first elastic member; and a second elastic member is disposed on the assembly. One of the spaces compresses the spring and is coupled to the limit block and The setting direction is an opposite end extending shape toward the protruding direction of the bolt, whereby when the dial button is toggled, the stopping surface of the dial is moved upward, and the bolt is driven by the second elastic member The matching mechanism causes the locking tongue to push outwardly and completely out of the opening, and the limiting block abuts against the brake seat, and the locking tongue can be rotated to perform the reversing action. However, it is not difficult to find out the above-mentioned conventional structure to see that there are still some shortcomings. The main reasons are as follows:

(1) One end of the button is placed in the penetrating portion of the assembly space, so that the button can slide along the penetrating portion, and the button and the inner wall of the assembly space are sandwiched with the second elastic member, There is a spacing between the penetrating portion and the second elastic member, so that when the button is not assembled, the button will be longitudinally inclined by the thrust of the second spring, and the first elastic member will laterally push the limit. Block The lateral push of the position block causes a lateral tilt. When the cover is assembled, the cover is also provided with a penetrating portion for providing a dial positioning. Since the dial is not easily fixed, the cover is difficult to assemble.

(2) The button is operated in the above-mentioned, sliding mode, and the button is longitudinally pushed by the second elastic member, and the lateral direction is pushed by the first elastic member, which causes the button to tilt against The penetration of the door lock, thus increasing the difficulty of pushing the button, resulting in a lack of operation.

(3) The door lock casing is made by multiple stamping and welding of metal plates, which will increase the processing cost and time.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

The technical problem to be solved by the present invention is to provide a door lock reversing adjustment structure for the above-mentioned defects existing in the prior art.

A casing is integrally cast from the aluminum material to form a side opening and a front opening, and the side opening is screwed to a front plate by a plurality of bolts, and a bolt hole is opened at the front plate, and the center of the casing is further A pivot hole is defined, a pivot hole is defined in one end of the pivot hole, and an arc slot is defined in the center of the shaft hole, and a blocking piece is protruded from the pivot hole and the shaft hole, and the blocking piece is provided with a shielding piece a groove, a locking tongue is provided with a head at one end, and a ring body is formed at the other end, the locking tongue is clamped at the groove of the housing, so that the blocking piece is disposed at the head of the locking tongue and the ring body And the head of the locking tongue is disposed on the locking tongue hole of the front panel, and a first spring is disposed between the ring body and the housing, and the locking tongue is provided with a convex portion at the end of the ring body, and The convex portion provides a sleeve of the first spring, and the housing is convexly provided with a limiting rib on both sides of the first spring at the position where the first spring is in contact with the first spring, thereby preventing the first spring from being displaced, and the pivoting of the shaft to the housing a pivot hole, and a swing arm extends from one end of the axial direction of the door handle, and a convex block is protruded from the swing arm, the swing arm A metal piece is arranged on the protrusion, so that the swing arm and the metal piece can simultaneously push the ring body to contract the locking tongue, and the casing protrudes from the periphery of the pivot hole with a ring portion, and the ring portion is sleeved with a torsion spring. One end of the torsion spring is hooked on the housing, and the other end is hooked on the door handle shaft. The torsion spring elastically drives the swing arm toward the head of the lock tongue, and one end of the swing button is set by a screw member. At the shaft hole of the housing, the other end of the knob is convex a stopper is arranged, and a second spring is interposed between the stopper and the casing, so that the stopper of the swing button normally blocks the ring body, so that the head of the lock tongue cannot pass through the bolt hole, and the knob is further a semi-circular block is protruded from the position where the second spring is in contact with the second spring, and the second spring is provided with a semi-circular block, thereby improving the positioning effect of the second spring, and the swing button is convexly provided with a short column on one side, and The short column is inserted into the arc groove of the casing to limit the position and the swing angle of the swing button, and the cover is locked with a plurality of bolts at the front opening of the casing, and the cover has a through hole for providing the door handle The shaft is pivoted, and the cover has a perforation corresponding to the shaft hole of the housing, so that the screw member can be exposed at the perforation, and then the screw member is rotated to generate a swing of the knob, so that the head of the bolt can The locking tongue hole is inserted to adjust the orientation, thereby being suitable for the assembled form of the left and right opening.

The first main purpose of the creation is that the housing has a shaft hole and a swing button The screw member is pivotally disposed at the shaft hole, and a second spring is disposed between the swing button and the housing, so that the stopper of the swing button can block the side of the ring body of the lock tongue, and the swing button is swinged. Adjusting the direction of the lock tongue, thereby improving the stability of the swing button operation, and the cover only needs to be provided with a perforation to provide the screw member to be exposed, so that it is not necessary to adjust the position of the screw member when the cover is locked The position, that is, the assembly steps can be easily completed, so as to improve its practicability.

The second main purpose of the creation is that the casing is integrally cast from aluminum. The front panel has a side opening and a front opening, and the front panel is bolted to the side opening, and the cover is bolted to the front opening, that is, the housing is assembled and closed, because the aluminum shell is integrally cast Forming, so there is no need to perform multiple stamping and welding processes, thereby saving processing costs and time.

The third main purpose of this creation is that the door handle has a bump at the swing arm. The metal piece is fixed by the bump, so that the metal piece can push the ring body of the lock tongue synchronously with the swing arm, the operation of shrinking the lock tongue in the casing, and improving the durability of the door handle shaft by utilizing the structural strength of the metal piece. .
