DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The embodiments of the present application provide a window closer for fireproof windows, thereby solving the problem that fireproof window closers are often easily installed in an improper position during installation. The rocker arm of the window closer is usually not easy to adjust, which makes the installation process inconvenient. If the length of the rocker arm of the window closer is not appropriate, subsequent debugging may not be in place, resulting in low installation quality and affecting the normal operation of the window closer.

[0028] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] The utility model embodiment discloses a fireproof window closer, according to the attached Figure 1-4 As shown, it comprises a window closer body 1, on which a main rocker arm 2 is provided, on which a secondary rocker arm 3 is rotatably connected, on which a movable column 6 is slidably connected, on which an extension rod 4 is fixedly connected, and on which a window fixing member 5 is rotatably connected;

[0030] The auxiliary rocker arm 3 is provided with an adjusting mechanism for adjusting the position of the movable column 6, and the adjusting mechanism includes:

[0031] The slider 601 is disposed on the movable column 6 and slidably connected to the auxiliary rocker arm 3;

[0032] A shaft seat 7 is arranged on the auxiliary rocker arm 3;

[0033] The screw rod 701 is rotatably connected in the shaft seat 7 , and the screw rod 701 is threadedly connected to the slider 601 .

[0034] Furthermore, the auxiliary rocker arm 3 is provided with a clamping assembly for limiting the position of the screw rod 701, and the clamping assembly includes:

[0035] A rotating handle 702 is provided on the screw rod 701;

[0036] The sleeve 7021 is arranged on the auxiliary rocker arm 3, and the rotating handle 702 is arranged in the sleeve 7021;

[0037] The bayonet 7022 is threadedly connected to the sleeve 7021 and is used to clamp the rotating handle 702. The overall structure of the clamping assembly is compact. The design of the rotating handle 702 makes it easy and labor-saving to rotate the screw rod 701. When the screw rod 701 needs to be positioned, the bayonet 7022 is directly rotated so that the bayonet 7022 clamps and limits the rotating handle 702, thereby limiting the screw rod 701, thereby keeping the distance between the auxiliary rocker arm 3 and the extension rod 4 stable.

[0038] Furthermore, a rubber ring 7023 is provided on the rotating handle 702 , and the rubber ring 7023 improves the clamping effect of the locking pin 7022 when clamping and limiting the rotating handle 702 .

[0039] Specifically, a slide groove 301 is provided on the auxiliary rocker arm 3, and the slider 601 is slidably connected in the slide groove 301. The slide groove 301 is set to limit the slider 601, ensuring that the slider 601 and the movable column 6 are stably stressed on the auxiliary rocker arm 3.

[0040] Furthermore, a first positioning pin 201 is movably connected between the main rocker arm 2 and the auxiliary rocker arm 3, and a second positioning pin 501 is movably connected between the window fixing member 5 and the extension rod 4. The first positioning pin 201 is set to stabilize the force between the main rocker arm 2 and the auxiliary rocker arm 3, and the second positioning pin 501 is set to stabilize the force between the window fixing member 5 and the extension rod 4.

[0041] The window closer for fireproof windows can conveniently adjust the distance between the auxiliary rocker arm 3 and the extension rod 4 during use, thereby facilitating the installation of the window closer body 1 and fireproof windows of various models. Through the design of the adjustment mechanism, the auxiliary rocker arm 3 and the extension rod 4 can be easily adjusted by directly rotating the screw rod 701. Therefore, the window closer body 1 and the fireproof window can be installed quickly, the position can be stable, the use effect is good, and the use requirements can be met.

[0042] When the screw rod 701 is rotated, the screw rod 701 drives the slider 601 to slide along the inside of the slide groove 301, the slider 601 drives the movable column 6 to slide along the inside of the auxiliary rocker arm 3, and the movable column 6 drives the extension rod 4 to move, thereby realizing the adjustment of the distance between the extension rod 4 and the auxiliary rocker arm 3 to meet the usage requirements.

[0043] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
