[0020] As shown in Figure 1 A telescopic prop with temperature control function, comprising a telescopic prop inner shell 3, a sliding groove 1 provided at one end of the telescopic prop inner shell 3, an automatic closing mechanism 5 slidingly arranged on the sliding groove 1, a heat-sensitive unlocking mechanism 2 provided between the automatic closing mechanism 5 and the sliding groove 1, the automatic closing mechanism 5 being fixed at one end of the sliding groove 1 through the heat-sensitive unlocking mechanism 2, one end of the telescopic prop inner shell 3 being rotatably connected to the automatic closing mechanism 5, the heat-sensitive unlocking mechanism 2 being unlocked after reaching a certain temperature, so that the automatic closing mechanism 5 slides along the sliding groove 1 and drives the telescopic prop inner shell 3 to move and close the window.
[0021] In actual practical process, the sliding groove 1 is installed in the window frame profile, the window frame and the sash are connected through the telescopic stay inner shell 3, and the sash is opened through the inner or outer tilt of the telescopic stay inner shell 3. Among them, the sliding groove 1 and the telescopic stay inner shell 3 are rotatably connected in the fixed state through the automatic closing mechanism 5, and the automatic closing mechanism 5 and the sliding groove 1 are slidably connected, and the automatic closing mechanism 5 and the sliding groove 1 are relatively fixed through the heat-sensitive unlocking mechanism 2. In normal use, the heat-sensitive unlocking mechanism 2 and the automatic closing mechanism 5 are fixed relative to the sliding groove 1, and the window is opened and closed through the telescopic stay inner shell 3, but when a fire or high temperature occurs, the heat-sensitive unlocking mechanism 2 will be unlocked when heated to a certain temperature, so that the automatic closing mechanism 5 can slide along the sliding groove 1, and when the automatic closing mechanism 5 slides along the sliding groove 1, it can automatically drive one end of the telescopic stay inner shell 3 to move downward, thereby realizing automatic closing of the opened door and window. So that the door and window can realize automatic closing at the first time when encountering fire outside, avoiding the spread of fire to the indoor, effectively ensuring the safety of the indoor, providing temperature control fireproof function for traditional telescopic stay, and also ensuring all functions of the existing telescopic stay inner shell 3,
[0022] Further improvement is that, as shown in Figure 2 The automatic closing mechanism 5 includes a sliding block 51 slidably arranged in the sliding groove 1, and a locking spring 52 arranged between the sliding block 51 and the sliding groove 1. The sliding block 51 is fixed at one end of the sliding groove 1 through the heat-sensitive unlocking mechanism 2, and one end of the telescopic stay inner shell 3 is rotatably connected to the sliding block 51. The heat-sensitive unlocking mechanism 2 is unlocked and pulled down the sliding block 51 through the locking spring 52.
[0023] The automatic closing mechanism is composed of a sliding block 51 slidably arranged in the sliding groove 1 and a locking spring 52 fixed at both ends between the sliding block 51 and the sliding groove 1. In normal state, the locking spring 52 is in tension state, and the sliding block 51 is fixed at one end of the sliding groove 1 through the heat-sensitive unlocking mechanism 2. When the heat-sensitive unlocking mechanism 2 is unlocked after being heated, the sliding block 51 is no longer fixed with the sliding groove 1. At this time, the sliding block 51 can be automatically pulled along the sliding groove 1 through the locking spring 52 in tension state, so as to realize the automatic closing of the opened window after the telescopic stay inner shell 3 is pulled, effectively solving the problem that the telescopic stay inner shell 3 has no power to drive closing, and the whole structure is simple, easy to operate and low in manufacturing cost.
[0024] Further improvement is that, as shown in
[0025] When the locking spring 52 is installed, the two ends of the locking spring 52 can be hung through the connecting column 6 and the connecting piece 7 for fixation, which is more convenient for the installation of the locking spring 52, especially the connecting piece 7 is formed by stamping to protrude into the groove, which has lower manufacturing cost and higher firmness because the connecting piece 7 is an integral structure with the sliding groove 1.
[0026] Further improvement is that, as shown in the figure, the heat-sensitive unlocking mechanism 2 comprises a swing piece 21 rotatably connected to the sliding block 51, a heat-sensitive piece 22 arranged on the swing piece 21, and a lock catch 9 arranged at the bottom of the swing piece 21. The sliding groove 1 is provided with a lock hole 10 for cooperation and fixation with the lock catch 9. The bottom of the swing piece 21 is relatively fixed after being connected with the lock hole 10 through the lock catch 9. The swing piece 21 is kept in balance through the heat-sensitive piece 22. The swing piece 21 swings after the heat-sensitive piece 22 explodes or melts. Figure 3 The swing piece 21 is rotatably installed on the sliding block 51, and the heat-sensitive piece 22 is installed on the swing piece 21. The swing piece 21 avoids swinging along the rotation shaft after being balanced by the heat-sensitive piece 22. The lock catch 9 is relatively fixed by being inserted into the lock hole 10 after moving along the sliding groove 1 by the sliding block 51. When the heat-sensitive piece 22 exists, the lock catch 9 is relatively locked and fixed with the lock hole 10. When the heat-sensitive piece 22 disappears due to melting or explosion, the swing piece 21 swings along the rotation shaft without the balance of the heat-sensitive piece 22, so that the lock catch 9 is separated from the lock hole 10, and the effect of unlocking is achieved. When a fire occurs, the temperature will inevitably rise sharply in a short time. Therefore, through the combination of the heat-sensitive piece 22 and the swing piece 21, the door and window can be timely unlocked and closed.
[0027] Further improvement is that the heat-sensitive piece 22 adopts an exploding bead or a hot-melt material.
[0028] When the heat-sensitive piece 22 adopts an exploding bead, the exploding bead will explode instantly when the temperature reaches the explosion temperature of the exploding bead, so that the heat-sensitive unlocking mechanism 2 can achieve instantaneous unlocking and closing of the door and window. When the heat-sensitive piece 22 adopts a hot-melt material, the hot-melt material will melt quickly after receiving flame combustion or high-position baking, so that the swing piece 21 achieves the purpose of imbalance.
[0029] Further improvement is that the sliding block 51 is provided with a positioning piece 4, the positioning piece 4 is provided with a limiting hole 8, and the swing piece 21 on which the heat-sensitive piece 22 is installed is located in the limiting hole 8.
[0030] Further improvement is that the sliding block 51 is provided with a positioning piece 4, the positioning piece 4 is provided with a limiting hole 8, and the swing piece 21 on which the heat-sensitive piece 22 is installed is located in the limiting hole 8.
[0031] A positioning member 4 with a limiting hole 8 is installed on the sliding block 51, the positioning member 4 is fixedly connected with the sliding block 51, the oscillating member 21 with the heat-sensitive member 22 is located in the limiting hole 8, after installation, the better concealment can be achieved, meanwhile, the heat-sensitive member 22 and the oscillating member 21 can be protected and prevented from being interfered, external interference can be avoided, meanwhile, when the heat-sensitive member 22 is broken, the function of collecting the fragments can be achieved, the influence of the fragments on the closing of the door and window can be avoided.
[0032] The above-mentioned embodiments are only the preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application, and any non-essential changes and replacements made by the person skilled in the art on the basis of the present application shall belong to the scope of protection of the present application.
