Detailed Description

The technical scheme of the invention is further described below with reference to the attached drawings and specific embodiments.

See a window closer shown in fig. 1-6, which is disposed between the window frame and the window jamb. The fireproof window closer comprises a window frame, a window body 1, a cylinder body 2 and a rocker arm 3, wherein the window body 1 is arranged on the window frame, the cylinder body 2 is arranged on the side frame of the window, and the two ends of the rocker arm 3 are respectively connected with the window body 1 and the cylinder body 2 in a rotating mode. The device body 1 comprises a sliding rail 4 fixed on the window frame, a sliding block 5 arranged in the sliding rail 4 and capable of sliding along the extending direction of the sliding rail 4, and a locking mechanism for limiting the sliding of the sliding block 5 in the sliding rail 4.

The locking mechanism comprises a positioning block 6 which can be movably and adjustably fixed in the sliding rail 4, a first clamping piece 8 and a second clamping piece 9 which are rotatably arranged on the positioning block 6 through a pivot 7, a lock frame 10 which is arranged along the length direction of the sliding rail 4 and fixedly connected with the positioning block 6, a locking piece 11 which is slidably arranged in the lock frame 10 and two sides of which are respectively abutted against the first clamping piece 8 and the second clamping piece 9, an elastic piece 12 which is respectively abutted against the locking piece 11 and the positioning block 6 at two ends, and a temperature sensing glass ball 13 which is respectively abutted against the locking piece 11 and the lock frame 10 at two ends, wherein the elastic piece 12 is used for enabling the locking piece 11 to tend to move towards the direction far away from the positioning block 6. The temperature sensing glass ball 13 limits the lock block 11 to move away from the positioning block 6, and the pivot 7 is perpendicular to the bottom surface of the sliding rail 4.

In this embodiment, the first clamping member 8 and the second clamping member 9 each include a main rod portion 14 rotatably connected to the positioning block 6 through the pivot 7, a spring piece 15 fixed to the main rod portion 14 near an end of the slider 5, and a locking portion 16 fixed to the main rod portion 14 near an end of the locking piece 11. The main lever portion 14 includes a first connecting portion 14a and a second connecting portion 14b disposed at an angle. When the locking parts 16 of the first clamping piece 8 and the second clamping piece 9 simultaneously rotate towards the middle part of the sliding rail 4, the spring piece 15 simultaneously rotates towards the side wall direction of the sliding rail 4; when the locking portion 16 rotates simultaneously in the side wall direction of the slide rail 4, the spring piece 15 rotates simultaneously in the middle direction of the slide rail 4. Preferably, the first clamping member 8 and the second clamping member 9 are symmetrically and rotatably arranged on the positioning block 6 through the same pivot 7.

The locking piece 11 is prismatic, the upper end surface of the locking piece is in contact with the elastic piece 12, and the lower end surface of the locking piece is in contact with the temperature sensing glass ball 13. The extending direction of the temperature-sensing glass ball 13 is the same as that of the slide rail 4. Grooves which are convenient for placing the temperature sensing glass balls 13 are arranged on the lock frame 10 and the lock block 11. Grooves which are convenient for placing the elastic piece 12 are arranged on the locking piece 11 and the positioning block 6.

When the locking mechanism is locked, the locking pieces 11 are abutted against the locking parts 16 at two sides, so that the locking parts 16 at two sides simultaneously rotate towards the side wall direction of the sliding rail 4, and the spring piece 15 simultaneously rotates towards the middle part direction of the sliding rail 4, so that the spring piece 15 is clamped at two sides of the sliding block 5, and the sliding block 5 is limited to slide. When a fire disaster occurs, when the ambient temperature reaches the critical temperature of the temperature-sensing glass ball 13, the temperature-sensing glass ball 13 is broken, the elastic piece 12 pushes the locking piece 11 away, so that the spring piece 15 loses the limiting force on the sliding block 5, and the sliding block 5 can slide along the extending direction of the sliding rail 4, thereby realizing window closing.

Preferably, the spring piece 15 includes a body and a clamping part 15a arched from the body to the middle of the sliding rail 4, a clamping locking area is formed between the two clamping parts 15a, and when the locking mechanism is locked, the clamping parts 15a are clamped at two sides of the sliding block. The both sides of slider 5 are equipped with the depressed part 5a that cooperatees with clamping part 15a, and when locking mechanism locking, clamping part 15a centre gripping is in depressed part 5a, and spring leaf 15 and slider 5 form the locking state, can make the locking effect better.

The two sides of the rear end of the sliding block 5 are provided with the protruding parts 5b, and the end parts of the spring pieces 15 are in contact fit with the protruding parts 5b in a propping mode to limit the sliding block 5 to move towards the direction of the positioning block 6, so that the sliding block 5 is prevented from colliding with the positioning block 6, and the practical service life of the window closer is prevented from being influenced. When the protruding portion 5b is abutted against the end portion of the spring piece 15, the clamping portion 15a can be driven to arch towards the middle portion of the sliding rail 4 to further clamp the sliding block 5, and therefore the sliding block 5 is limited to move towards the direction of the positioning block 6. The end of the sliding block 5 close to the positioning block 6 is arranged in a sharp mouth shape so as to extend into the clamping and locking area conveniently.

In summary, in the present embodiment, the window closer has two use states:

1. in a safe state, the window closer can be normally used. When the window needs to be opened, the window is manually pushed open, so that the window drives the cylinder body 2 to move, the cylinder body 2 drives the rocker arm 3 to move, and the rocker arm 3 drives the sliding block 5 to move along the length direction of the sliding rail 4 in a direction close to the positioning block 6. The front end portion of the slider 5 passes through the clamp lock area until the recess 5a is engaged with the clamp portion 15a of the spring piece 15. Therefore, the locking mechanism is locked, the window is kept in an open state, and the locking effect is better. Meanwhile, the fixed position of the positioning block 6 in the sliding rail 4 can be controlled to determine the opening amplitude of the window. When the window needs to be closed, the window is pulled forcefully, so that the sliding block 5 is withdrawn from the clamping and locking area, and the rocker arm 3 drives the sliding block 5 to continuously move in a direction away from the positioning block 6 under the action of the self gravity of the cylinder body 2 and the window until the window is closed.

2. In the event of a fire. When the ambient temperature reaches the critical temperature of the temperature-sensing glass ball 13, the temperature-sensing glass ball 13 is broken, the elastic piece 12 pushes the locking piece 11 to a direction away from the positioning block 6, so that the locking piece 11 is separated from the locking parts 16 at one end parts of the first clamping piece 8 and the second clamping piece 9, the spring piece 15 at the other end parts of the first clamping piece 8 and the second clamping piece 9 loses the limiting force on the sliding block 5 according to the lever principle, and the rocker arm 3 drives the sliding block 5 to continuously move to a direction away from the positioning block 6 under the action of the gravity of the cylinder body 2 and the window until the window is closed. The door closer has the advantages of sensitive response, quicker unlocking and good fireproof effect.
