Detailed Description
The technical scheme of the invention is further described below with reference to the attached drawings and specific embodiments.
Referring to fig. 1-3, a fire protection window closer is shown disposed between a window frame and a 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 includes a slide rail 4 fixed to the window frame, a slider 5 provided in the slide rail 4 and slidable along an extending direction of the slide rail 4, a lock mechanism 6 for restricting the slider 5 from sliding in the slide rail 4, and an unlock mechanism 11 for driving the lock mechanism 6 to unlock.
The locking mechanism 6 includes a positioning block 7 movably and adjustably fixed to the slide rail 4, a locking lever 8 pivotally provided at the positioning block 7 from the middle, a locking piece 9 provided at one end portion of the locking lever 8 (i.e., an end portion near the slider 5), and a driving assembly 10 provided at the other end portion of the locking lever 8 (i.e., an end portion far from the slider 5). Wherein the locking lever 8 is driven to rotate by the driving assembly 10 such that the locking member 9 is cooperatively locked with the slider 5 to restrict the movement of the slider 5.
The unlocking mechanism 11 comprises a temperature-sensing glass ball 12 with two ends abutting between the positioning block 7 and the driving assembly 10. When a fire disaster occurs and the ambient temperature reaches the critical temperature of the temperature-sensing glass ball 12, the temperature-sensing glass ball 12 is broken, and the driving assembly 10 causes the locking piece 9 to lose the limiting force on the sliding block 5, so that the sliding block 5 can slide along the extending direction of the sliding rail 4, and window closing is realized.
The driving assembly 10 comprises a guide block 13 movably arranged in the slide rail 4 and a driving piece 14 for keeping the guide block 13 moving away from the positioning block 7. Wherein the other end part (the end part close to the guide block 13) of the locking rod 8 is movably connected to the guide block 13, and the locking rod 8 rotates around a pivot under the driving of the guide block 13, so that the locking piece 9 of the locking rod 8 close to the end part of the sliding block 5 can be limited on the sliding block 5.
In the present embodiment, the guide block 13 is provided with a guide groove 15 extending obliquely from a direction away from the positioning block 7 to a direction toward the positioning block 7, and the other end portion (one end portion near the guide block 13) of the lock lever 8 is provided with a link 16 slidably provided in the guide groove 15. When the guide block 13 moves along the length direction of the sliding rail 4, the connecting piece 16 can move along the length direction of the guide groove 15, and the locking piece 9 of the locking rod 8, which is close to one end of the sliding block 5, is limited on the sliding block 5 according to the lever principle, so that the sliding block 5 is locked. As a specific embodiment, the guide groove 15 extends upwards obliquely from the bottom of the slide rail 4 to the direction close to the positioning block 7, so that when the guide block 13 moves along the slide rail 4 to the direction far away from the positioning block 7, the connecting piece 16 can move upwards along the length direction of the guide groove 15, and according to the lever principle, the locking piece 9 of the locking rod 8 close to one end of the slide block 5 moves to the bottom close to the slide rail 4, so that the locking piece 9 is limited on the slide block 5, and thus the slide block 5 is locked.
Preferably, the locking mechanism 6 comprises two locking rods 8 symmetrically arranged on both sides of the positioning block 7. The both ends of locking piece 9, connecting piece 16 are connected with two locking bars 8 respectively, still are equipped with the dead lever between two locking bars 8 to make locking mechanical system 6 more firm, the locking effect is better. The roller 17 is sleeved on the locking piece 9 and the connecting piece 16, so that the locking piece is more stable in the locking process, and meanwhile, the abrasion in the locking process is reduced.
The driving member 14 includes a positioning seat 18 provided on the positioning block 7 so as to be movable along the length of the slide rail 4, and an elastic member 19 interposed between the positioning seat 18 and the guide block 13. The two ends of the temperature sensing glass ball 12 are respectively abutted against the positioning seat 18 and the positioning block 7, and the elastic piece 19 enables the guide block 13 to move in a direction away from the positioning block 7. In this example, the temperature sensing glass ball 12 and the positioning seat 18 can also be arranged on the guide block 13, so that the same technical effect can be achieved, and the scheme is also within the protection scope of the patent application. Preferably, the temperature sensing glass ball 12 and the elastic member 19 are arranged in a staggered manner, and most preferably, the temperature sensing glass ball 12 and the elastic member 19 are arranged in parallel, and the temperature sensing glass ball 12 is arranged on the upper side of the positioning block 7. The temperature sensing glass ball 12 is close to the opening of the sliding rail 4, so that the temperature sensing glass ball can sense the outside temperature more sensitively. Wherein, the positioning seat 18 and the guide block 13 are respectively provided with a positioning hole for conveniently placing the elastic piece 19, which plays a role in stabilizing the elastic piece 19. Preferably, when the guide block 13 is located at the position closest to the positioning block 7, the bottoms of the two positioning holes are separated by a length greater than the length of the elastic member 19 in the natural state. The purpose is that the elastic member 19 does not give any pushing force to the guide block 13 after the breaking of the temperature sensitive glass bulb 12, so that the slider 5 can be easily separated from the locking member 9.
A boss 20 is arranged on one side of the slide block 5 close to the positioning block 7, and a positioning groove 21 with an arc-shaped section is formed in the boss 20. The locking piece 9 of the locking rod 8 near one end of the slide 5 can be cooperatively pressed in the positioning groove 21 to form a lock for the slide 4 so as to limit the movement of the slide 5. Preferably, the radian of the positioning groove 21 is smaller than 180 degrees, so that when the unlocking mechanism 11 is unlocked, the locking piece 9 can smoothly slide out of the positioning groove 21, and the unlocking effect is not affected.
Meanwhile, one side of the boss 20, which is close to the positioning block 7, is inclined to an inclined plane extending upwards from the bottom of the boss 20 to the direction of the sliding block 5, so that when one end part of the locking rod 8, which is close to the sliding block 5, is pressed on the bottom of the sliding rail 4, the boss 20 can push the locking piece 9 upwards, and the locking piece 9 is matched and locked with the positioning groove 21.
The specific work of the fireproof window closer is as follows:
under normal use conditions, the guide block 13 tends to move away from the positioning block 7 under the pushing of the elastic member 19, so that the connecting member 16 is at the uppermost end of the guide groove 15, and according to the lever principle, the locking member 9 at the end of the locking rod 8 near the sliding block 5 is at the bottommost end near the bottom of the sliding rail 4. I.e. the drive assembly 10 drives the locking lever 8 in rotation. When the window needs to be opened, the sliding block 5 moves along the length direction of the sliding rail 4 towards the direction close to the positioning block 7, the boss 20 pushes the locking piece 9 upwards from the lower end of the locking piece 9, and then the locking piece 9 and the roller 17 are pressed into the positioning groove 21 of the boss 20. Since the driving assembly 10 still has a tendency to drive the locking rod 8 to rotate at this time, the locking piece 9 and the roller 17 are pressed into the positioning groove 21 of the boss 20, so that the sliding of the sliding block 5 can be limited, and the locking of the sliding block 5 can be realized. When the window is required to be closed, the window is pulled forcefully, and the sliding block 5 moves away from the positioning block 7 along the length direction of the sliding rail 4 under the drive of the rocker arm 3. Under the action of external force, the locking piece 9 and the roller 17 are pressed and separated from the positioning groove 21 of the boss 20, and the locking mechanism 6 is disabled. So that the window can be normally opened and closed. Meanwhile, the fixed position of the positioning block 7 in the sliding rail 4 can be controlled to determine the opening amplitude of the window.
In case of fire, when the ambient temperature reaches the critical temperature of the temperature sensing glass ball 12, the temperature sensing glass ball 12 is broken, the positioning seat 18 is out of abutment, so that one end of the elastic piece 19 is out of abutment, and the elastic piece 19 cannot push the guide block 13 to move in a direction away from the positioning block 7. The end of the locking rod 8 near the guide block 13 is not driven, and the locking piece 9 and the roller 17 at the end of the locking rod 8 near the sliding block 5 lose the force of the pressing boss 20 according to the lever principle, so that the locking mechanism 6 is disabled. The sliding block 5 is driven by the rocker arm 3 and the cylinder body 2 to rapidly slide in a direction away from the positioning block 7, so that the window is closed, and the aim of fire prevention is fulfilled.
The above embodiments are provided to illustrate the technical concept and features of the present invention and are intended to enable those skilled in the art to understand the content of the present invention and implement the same, and are not intended to limit the scope of the present invention. All equivalent changes or modifications made in accordance with the spirit of the present invention should be construed to be included in the scope of the present invention.
