Description

Transmission automatic locking device that fire prevention window was used

Technical Field

The utility model relates to the technical field of building hardware accessories, in particular to a transmission automatic locking device for a fireproof window.

Background

At present, when a common fire window is normally operated, driving parts such as a handle and the like are generally required to be rotated, and locking points inside the window are buckled with each other to realize locking. When a fire occurs, the fire window generally has a structure for closing a window sash, the structure only achieves automatic closing, but the window sash is still possibly opened secondarily due to lack of locking point buckling, so that the sealing performance is insufficient, potential safety hazards exist, the locking needs manual operation, and the fire window is difficult to realize in the fire, so that the fire window is difficult to realize by a single closing structure.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provides a transmission automatic locking device for a fire window, which has a novel and reliable structure, can realize automatic locking and has a simple unlocking mode.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: a transmission automatic locking device for a fire window comprises a first assembly and a second assembly which are respectively arranged on a window sash and a window frame, wherein the first assembly comprises a transmission rod, a sliding seat which is connected to the transmission rod in a sliding manner and a reset unit which drives the sliding seat to reset; the two ends of the second component are respectively provided with a lock catch part which is matched and buckled with the lock point and a convex block which is matched with the shifting piece, when the transmission rod is positioned at a first point, the lock point is aligned with the lock catch part, and when the transmission rod is positioned at a second point, the lock point and the lock catch part as well as the shifting piece and the convex block are staggered mutually.

The utility model has the beneficial effects that: the transmission automatic locking device can realize automatic locking, has simple unlocking mode operation, can avoid misoperation to a certain extent, and has good safety. Specifically, the transmission rod can move between a first position point and a second position point through operation, when the transmission rod is located at the first position point, the locking point is aligned with the lock catch portion, and at the moment, the window sash is closed, so that the locking point and the lock catch portion can be matched and buckled with each other, and the window sash is locked. When the transmission rod is positioned at the second point, because the locking point, the locking part, the shifting sheet and the lug are staggered, if the first component and the second component of the window sash are closed at the moment, the window sash can be closed smoothly.

Preferably, the transmission rod is provided with a sliding groove for guiding the sliding base. The sliding base can be guided to slide on the transmission rod stably by the sliding groove.

Preferably, arc-shaped or wedge-shaped guide surfaces are formed on two sides of the lock catch portion, and when the lock catch portion is abutted against the guide surfaces, the sliding seat slides to avoid the lock catch. The guide surface can guide the sliding seat to slide to avoid the locking point, and the resistance force when the sliding seat is collided with the locking point is reduced, so that the window sash can be smoothly closed.

Preferably, the plectrum adopts the elastic material, and the plectrum is formed with the direction inclined plane, works as when the lug contradicts with the direction inclined plane the plectrum elastic deformation is in order to dodge the lug. The guide inclined plane can guide the shifting piece to generate elastic deformation, and the resistance when the shifting piece is collided with the guide inclined plane is reduced.

Detailed Description

The claimed invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 7, the driving automatic locking device for a fire window in the present embodiment includes a first module 1 and a second module 2 respectively mounted on a window sash and a window frame. In this embodiment, the first component 1 is mounted on the sash and the second component 2 is fixedly mounted on the frame. In other embodiments, the specific installation manner of the first assembly 1 and the second assembly 2 can be adjusted according to actual needs.

The first assembly 1 includes a transmission rod 11, a slider 12 slidably connected to the transmission rod 11, and a reset unit 13 for driving the slider 12 to reset, the transmission rod 11 is provided with a sliding slot 111 for guiding the slider 12, the sliding direction of the slider 12 is parallel to the moving direction of the transmission rod 11, and the slider 12 is provided with a locking point 121 and a shifting piece 122 at two ends of the sliding direction thereof. In this embodiment, the return unit 13 is a spring, the lever 11 is moved by the handle 3, and the lever 11 is also coupled to the locking mechanism 4.

The two ends of the second component 2 are respectively provided with a locking part 21 which is matched and buckled with the locking point 121 and a convex block 22 which is matched with the shifting piece 122, in this embodiment, arc-shaped or wedge-shaped guide surfaces 211 are formed on two sides of the locking part 21, when the locking point 121 is abutted against the guide surfaces 211, the sliding base 12 slides to avoid the locking point 121, the guide surfaces 211 can guide the sliding base 12 to slide to avoid the locking point 121, and the resistance when the sliding base is abutted against the guide surfaces 211 is reduced, so that the window sash can be smoothly closed. The shifting piece 122 is made of an elastic material, the guiding inclined plane 1221 is formed on the shifting piece 122, when the protruding block 22 collides with the guiding inclined plane 1221, the shifting piece 122 elastically deforms to avoid the protruding block 22, and the guiding inclined plane 1221 can guide the shifting piece 122 to elastically deform, so that the resistance of the two colliding is reduced.

The use principle of the automatic transmission locking device in the embodiment is as follows:

when the handle 3 is at 0 degrees, the transmission rod 11 is at the first position, and the locking point 121 is aligned with the locking portion 21. When the window sash is closed, the locking point 121 is abutted against the guide surface 211 to drive the sliding seat 12 to slide and avoid the locking point 121, so that the window sash can be smoothly closed, and finally, when the lower sliding seat 12 is driven by the resetting unit 13 to reset, the locking point 121 and the locking part 21 are mutually buckled to realize the locking of the window sash.

After the handle 3 is rotated to 90 degrees, the transmission rod 11 moves from the first position point to the second position point, in the process, when the protrusion 22 collides with the guiding inclined surface 1221, the shifting piece 122 elastically deforms to avoid the protrusion 22, and finally the transmission rod 11 is smoothly switched to the second position point, and at this time, the locking point 121 and the locking part 21 are dislocated with each other, and the shifting piece 122 and the protrusion 22 are dislocated with each other. In this embodiment, when the drive is in the second position, the locking mechanism associated with the drive rod 11 locks the sash and frame, so that the sash remains locked even if the locking point 121 and the locking portion 21 are misaligned. The handle 3 needs to be further rotated to 0 degree to unlock the window sash, so that the transmission rod 11 returns to the first position point from the second position point, the protruding block 22 will collide with the shifting piece 122 and push the sliding seat 12 to slide in the process, after the transmission rod 11 returns to the first position point, the locking nail and the locking part 21 still keep dislocation due to the collision of the shifting piece 122 and the protruding block 22, and the locking mechanism 4 is switched to an unlocking state by the linkage of the transmission rod 11, so that the window sash is unlocked, and the window sash can be freely closed at the moment.
