Description

Light touch type lock tongue device

Technical Field

The invention relates to a device installed on a door body, in particular to a device for controlling a spring bolt of a spring lock on the door body.

Background

The soft touch type spring bolt device is a device which can make the spring bolt pop out only by slightly touching a certain touch piece in the device when the door is closed. The device can avoid the noise generated by the collision of the bolt and the lock catch on the doorframe when the door is closed. However, the existing devices are all installed on the door surface of the door panel, which seriously affects the appearance of the door, and needs to modify the original lock, and has complex structure and higher manufacturing cost.

Disclosure of Invention

The invention aims to provide a light-touch type spring bolt device which does not affect the appearance of a door surface of a door plate and has a simple structure.

The invention is realized by the following steps: a light touch type spring bolt device is characterized in that a touch piece is connected to the side surface of a door plate in a sliding mode, when the door is closed, the touch piece can be pressed by a door frame to slide, and the sliding direction of the touch piece is perpendicular to the telescopic direction of a spring bolt of a door lock; the contact piece is fixed with a separation blade, the separation blade is shielded in front of a spring lock tongue of the door lock in a door opening state, so that the spring lock tongue keeps a contracted state, and after the contact piece is pressed by a door frame to slide, the separation blade deviates from the spring lock tongue, so that the spring lock tongue can freely extend out; the touching piece is connected with the spring, and at the in-process of unblanking, after the spring bolt shrink of lock, this spring makes touching piece drive the separation blade and slides together, makes the separation blade shelter from in spring bolt the place ahead.

Preferably, the touching piece is a U-shaped rod, two straight line segments of the U-shaped rod are respectively sleeved in the two hollow tubes and can slide along the hollow tubes, the hollow tubes are fixed on the side surface of the door plate, the blocking piece spans between the two straight line segments fixed on the U-shaped rod, the spring is two helical compression springs, the two helical compression springs are respectively sleeved on the two straight line segments of the U-shaped rod, one end of each helical compression spring is pressed against the blocking piece, the other end of each helical compression spring is pressed against a fixed seat, and the fixed seat is fixed on the side surface of the door plate.

Preferably, the U-shaped bar is a strip of U-shaped wire.

The invention has the advantages that: whole device is located the side of door plant, and whole device is hidden in the gap between door plant side and door frame under the state of closing the door, can not see the device almost, has no influence to the outward appearance of door, need not to reform transform original tool to lock moreover, simple structure, low in manufacturing cost.

Drawings

FIG. 1 is a schematic structural diagram of an embodiment of the present invention;

fig. 2 is a schematic view of the device of fig. 1 in a closed door state.

Detailed Description

Referring to fig. 1, the touch type deadbolt assembly provided according to the present invention includes a touch member 3 installed at a side of a door panel 1. The touch piece 3 is a U-shaped bar. Two straight line sections of the U-shaped rod 3 are respectively sleeved in the two hollow pipes 4 and can slide along the hollow pipes 4, and the hollow pipes 4 are fixed on the side surface of the door plate 1, so that the sliding connection between the U-shaped rod 3 and the side surface of the door plate 1 is formed. When the door is closed, the right end of the illustrated U-shaped rod 3 can be pressed by the door frame to slide, and the sliding direction is perpendicular to the extension direction of the spring bolt 2 of the door lock.

A baffle 5 is fixed between the two straight line sections of the U-shaped rod 3 in a crossing way. In the door-opening state, i.e. the state shown in fig. 1, the blocking piece 5 blocks the front of the spring bolt 2, so that the spring bolt 2 keeps the contraction state. When the door is closed, when the right end of the U-shaped rod 3 is pressed by the door frame and slides, as shown in fig. 2, the U-shaped rod 3 drives the catch 5 to deviate from the spring bolt 2, and the spring bolt 2 can freely extend. It should be noted that the door panel 1 in fig. 2 is in a closed state, the right end of the U-shaped bar 3 is against the doorframe, and the extended spring bolt 2 is inserted into the locking hole of the doorframe, so the doorframe should be illustrated in fig. 2. But this will cause the entire device to be obscured by the door frame and not displayed. Thus, the door frame is omitted from fig. 2 for clarity of illustration of the entire device.

Referring to fig. 1, two straight line segments of the U-shaped rod 3 are respectively sleeved with a helical compression spring 6. One end of the spiral compression spring 6 is propped against the separation blade 5, and the other end of the spiral compression spring is propped against a fixed seat 7. The fixed seat 7 is an angle iron formed by bending a thin iron sheet and is fixed on the side surface of the door panel 1. During unlocking, when the spring bolt 2 is retracted by a user's unlocking action (e.g., turning a key), the helical compression spring 6 urges the U-shaped rod 3 to drive the blocking piece 5 to slide together, so that the blocking piece 5 is shielded in front of the spring bolt 2, and at this time, as shown in fig. 1, the blocking piece 5 keeps the spring bolt 2 in a retracted state.

It can be seen from the attached drawing that the whole soft-touch bolt device is located on the side of the door plate 1, therefore, the whole device is hidden in the gap between the side of the door plate 1 and the door frame in the door closing state, the device can not be seen almost, the appearance of the door is not affected, the original lockset is not required to be transformed, the structure is simple, and the manufacturing cost is low.

In a preferred embodiment, the U-shaped bar 3 of this embodiment is a strip of U-shaped wire. This allows the entire device to be made as flat as possible.

It should be noted that the door frame of the present invention, especially the door frame portion of the pressing touch member, not only refers to the door frame itself, but also can be an additional member such as a latch fixed on the door frame.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. The protection scope of the present invention should be subject to the appended claims.
