Description

Door opener device for casement door

TECHNICAL FIELD

The invention relates to a door opener device for a casement door.

Prior art prior to the present invention

Existing hinged door openers usually use a hydraulic or spiral telescopic rod mechanism to drive the door body to close the door. The shortcomings are: one is that the rod and the door are under great force, and the mechanism is easily damaged; the other is that the transmission efficiency is low. Installation is inconvenient. Fourth, it is bulky, the structure is not compact, and the appearance is affected. In addition, when the door is closed in place, it is usually necessary to lock the door by means of a latch or latch, which is obviously inconvenient to operate.

Object of the invention

An object of the present invention is to provide a door opener device for a self-locking hinged door when the door is in place.

Technical solution used by the present invention

The invention is constituted in such a way that it includes a machine body with a runner installed on the lower side edge of the door body, and is characterized by: (1) a transmission device provided on the machine body to drive the operation of the runner is provided with a worm gear; Transmission mechanism; (2) gears are arranged on the runner body; (3) racks are provided on the ground where the door body is closed in place to mesh with the gears.

When the device is in operation, the wheel is driven to rotate by the worm gear, thereby driving the door body to open and close. When the door is closed in place, if the door is to be pushed, because the runner cannot drive the worm and worm gear in the reverse direction, the runner is forced to stop rotating. At this time, due to the meshing effect of the rack and pinion provided on the runner, The runner rotates the door body through sliding on the ground, thereby realizing the reliable self-locking of the door body. Compared with the existing door opener device of the casement door, the present invention not only has a self-locking and reliable structure, but also has a compact structure, high transmission efficiency, and convenient operation.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic structural diagram of an embodiment of the present invention.

Fig. 2 is a left side view of Fig. 1.

Examples

The invention is constituted in such a way that it includes a machine body 2 with a runner 1 installed on the lower side edge of the door body, and is characterized by: (1) a transmission device provided on the machine body for driving the runner to rotate is provided with The worm gear transmission mechanism 3; (2) a gear 4 is arranged on the runner body; (3) a rack 6 is provided on the ground 5 with the door body closed in place to mesh with the gear.

The rack mentioned above is provided with a turning head 7, and the body of the corresponding side of the runner is provided with a hook head 8 which can hold the turning head when the door is closed in place.

The above-mentioned transmission device may be composed of a motor 9, a worm gear transmission mechanism, and a sprocket or gear transmission mechanism 12 coupled between the worm wheel rotation shaft 10 and the wheel rotation shaft 11.

When working, the motor drives the worm and worm to rotate and drives the runner to rotate through the sprocket transmission mechanism, thereby driving the door switch. When the door is in place, if you want to push the door in the opposite direction, because the runner cannot drive the worm and worm gear in the reverse direction, the runner is forced to stop rotating. At this time, on the one hand, due to the meshing effect of the gear bar provided on the runner body, The runner is prevented from driving the door body through sliding on the ground, so that the door body cannot be pushed open in the reverse direction, thereby achieving a firm lock of the door body in the horizontal direction; on the other hand, when the door body is closed in place, the setting The hooks on the body of the corresponding side of the runner fasten the crutches at the rack, so that the door cannot be lifted upward, thereby achieving a secure lock in the vertical direction of the door. In order to prevent the worm and worm from stopping due to a power outage or failure, the door body cannot be moved. A tapered sleeve 14 is provided in the tapered cavity 13 at one end of the runner shaft. The tapered sleeve is passed through the middle channel A bolt 15 is connected to the threaded hole in the middle of the runner shaft. When the user loosens the bolt with a randomly configured tool and pushes the door body to open and close with the runner, the runner cone cavity acts on the tapered sleeve body. The axial component of the reaction force will disengage the tapered sleeve body from the tapered cavity, so the tapered sleeve body is separated from the tapered cavity, and the runner is released from the shackle of the sprocket drive mechanism, so that the user can push the door by hand only. Body can open or close the door.

In order to facilitate the door body to travel on the uneven ground, the machine body with the runner is installed on the positioning plate 16 located on the lower side edge of the door body. The rail body 18 is provided with a tension spring assembly 19 between the slide rail body and the chute. The lower end of the tension spring is coupled to the lower side portion of the positioning plate, and the upper end is coupled to the upper side portion of the body. When the door body hits a bump on the ground during the movement, the reaction force of the bump against the caster will push up the caster, causing the body to move upward through the slide rail of the positioning plate along the sliding groove of the positioning plate in order to overcome the obstacle After passing the obstacle, the body returns to its position under the action of the restoring elasticity of the tension spring, so that the casters can always keep running smoothly on the ground.

In addition, the upper end of the above-mentioned tension spring is connected to the upper side of the body through the elasticity adjustment bolt 20, and before use, the user can set the pretension force of the tension spring by rotating the elasticity adjustment bolt, thereby adjusting the pressure of the body on the ground.

The invention is not only novel in concept, compact in structure, but also high in transmission efficiency and reliable in work, and has a considerable application prospect.
