Abstract

The utility model discloses a transverse knob lock structure for a sliding door, which comprises a lock tongue, a fixed plate and a locking mechanism, wherein the lock tongue is fixedly arranged on a rotatable knob rotating shaft; an elastic positioning device is further arranged on the upper portion of the fixed plate and connected with the knob rotating shaft; when the knob rotating shaft is twisted by external force and drives the lock tongue to fall down to be blocked against the blocking bolt, the elastic positioning device abuts against the knob rotating shaft so as to enable the lock tongue to abut against the blocking bolt; when the knob rotating shaft is twisted by external force and drives the lock tongue to lift and separate from the clamping bolt, the elastic positioning device abuts against the knob rotating shaft so as to enable the lock tongue to keep a lifted state. The utility model not only ensures that the lock tongue is firmly abutted against the clamping bolt and is not loosened, but also avoids the influence of unexpected falling when the lock tongue is lifted to the subsequent closing of the sliding door.

Description

Transverse knob lock structure for sliding door

Technical Field

The utility model relates to a lock structure, in particular to a transverse knob lock structure for a sliding door.

Background

The sliding door realizes space isolation by transversely opening or closing the door leaf.

In the prior art, the door leaf of a sliding door is locked by arranging a padlock or a hook at the side edge of the sliding door. The hook which can be clamped and hung on the fixing bolt is arranged, and then the hook is driven to lift or release by twisting the knob, so that the hook is hung on the fixing bolt by means of the gravity of the hook. The disadvantage of this structure is that the hook cannot be locked in the hooking position, so that the problem of loosening due to loose hooking with the fixing bolt can occur; furthermore, the position of the hook after being lifted off the fixing bolt cannot be locked, and the subsequent hooking operation can be influenced if the hook falls under unexpected stress.

Detailed Description

The present utility model is described in further detail below with reference to the drawings to enable those skilled in the art to practice the utility model by referring to the description.

As shown in fig. 1, 2 and 3, the horizontal knob lock structure for sliding doors of the present utility model comprises a lock tongue 4 provided with a clamping groove 40, wherein the lock tongue 4 is fixedly arranged on a rotatable knob rotating shaft 3. In the horizontal knob lock structure for the sliding door, the fixing plate 12 for accommodating the knob rotating shaft 3 is further arranged, so that the knob rotating shaft 3 is rotatably arranged in the accommodating opening 15 at the lower part of the fixing plate 12.

An elastic positioning device 5 is also arranged at the upper part of the fixed plate 12, and the elastic positioning device 5 is connected with the knob rotating shaft 3. In this way, when the knob rotating shaft 3 is twisted by an external force and drives the lock tongue 4 to drop and be blocked against the blocking bolt 21 in the fixed frame 2 arranged at the side of the sliding door 1, the elastic positioning device 5 abuts against the knob rotating shaft 3, so that the position of the knob rotating shaft 3 is locked, and the lock tongue 4 abuts against the blocking bolt 21 (as shown in fig. 1). On the contrary, when the knob rotating shaft 3 is twisted by an external force and drives the lock tongue 4 to lift away from the locking bolt 21, the elastic positioning device 5 abuts against the knob rotating shaft 3 to lock the position of the knob rotating shaft 3, so that the lock tongue 4 is kept in a lifted state (as shown in fig. 2). In order to prevent the knob shaft 3 from rotating excessively in the state shown in fig. 2, a clamping protrusion (not shown in the figure) may be further disposed on the knob shaft 3, and the deflection angle of the knob shaft 3 may be limited by the cooperation of the clamping protrusion and a clamping post (not shown in the figure) disposed on the fixing plate 12.

In the horizontal knob lock structure for sliding door of the present utility model, the elastic positioning device 5 may be specifically an elastic steel belt with a middle portion 52 wound (i.e. the middle portion 52 is wound one or more times), and one end 52 and the other end 53 led out reversely. The upper end of the elastic steel band is rotatably disposed on the pivot 16 protruding vertically from the fixing plate 12, so that the elastic steel band can rotate around the pivot 16 in the vertical plane direction. The lower end of the elastic steel belt is rotatably arranged on the outer wall of the knob rotating shaft 3 and can rotate in the vertical plane direction along with the rotation of the knob rotating shaft 3.

The total length of the wound elastic steel band (i.e. the distance between the upper end and the lower end of the elastic steel band) is greater than the shortest distance between the pivot 16 and the knob rotating shaft 3, so that a sufficient pushing elastic force can be applied to lock the knob rotating shaft 3 when the knob rotating shaft 3 rotates to a left fixed position (as shown in fig. 2). Along with the rotation knob 31 of the rotation knob rotating shaft 3 driven by the clockwise external force, the rotating shaft 32 also rotates along with the rotation knob, and further drives the lower end of the elastic steel belt to rotate rightwards. The elastic steel strip is pressed and deformed and gradually released after passing over the position right below the pivot 16, when the lock tongue 4 is clamped against the clamping bolt 21, the elastic steel strip applies pushing elastic force to the knob rotating shaft 3, so that the knob rotating shaft 3 is locked at the current position (as shown in fig. 1). And vice versa.

In order to limit the movement track of the elastic steel belt and ensure that the elastic steel belt can be reliably pushed and sprung to the knob rotating shaft 3 at the left side and the right side, the middle part of the fixing plate 12 vertically protrudes out of the right supporting vertical wall 14, and when the knob rotating shaft 3 drives the lower end of the elastic steel belt to deflect rightwards to enable the lock tongue 4 to abut against the clamping bolt 21, the elastic steel belt abuts against the right supporting vertical wall 14. Similarly, the tail of the fixing plate 12 may further vertically protrude out of the left supporting vertical wall 13, and when the knob rotating shaft 3 drives the lower end of the elastic steel belt to deflect left to make the lock tongue 4 keep the lifted state, the elastic steel belt tightly abuts against the left supporting vertical wall 13.

According to the utility model, the elastic positioning device 5 is arranged to push and lock the knob rotating shaft 3 in the two boundary position states, so that the lock tongue 4 can firmly abut against the clamping bolt 21 and cannot loosen, and the influence on the subsequent closing of the sliding door caused by accidental falling when the lock tongue 4 is lifted is avoided.

Although embodiments of the present utility model have been disclosed above, it is not limited to the details and embodiments shown and described, it is well suited to various fields of use for which the utility model would be readily apparent to those skilled in the art, and accordingly, the utility model is not limited to the specific details and illustrations shown and described herein, without departing from the general concepts defined in the claims and their equivalents.
