Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1 to 5, a pause type door sucker comprises a base 1, two pulleys 2 and a baffle 3, wherein the base 1 is installed at the lower end of a door leaf, a rotating shaft 4 is rotatably installed at the lower end of the base 1, the two pulleys 2 are respectively and symmetrically installed on the rotating shaft 4, a first sliding chute 41 is formed in the middle of the rotating shaft 4, an installation seat 5 is sleeved in the first sliding chute 41, a through hole 51 is formed in the lower end of the installation seat 5, two symmetrically arranged sliding rods 6 are slidably installed in the through hole 51 at the lower end of the installation seat 5, first contact heads 7 are fixed at the lower ends of the two sliding rods 6, a top plate 8 is fixed at the upper end of the sliding rod 6, a spring 9 is sleeved between the top plate 8 and the inner bottom surface of the through hole 51 on the sliding rod 6, the baffle 3 is two L-shaped baffles and respectively fixed at the two side ends of the base 1, and two sliding chutes 31 are, sliding plates 10 are arranged in the second sliding grooves 31 in a sliding mode, one end face, close to the pulley 2, of each sliding plate 10 is fixed to the two sides of the top plate 8, and one end, far away from the pulley 2, of the baffle plate 3 is provided with a second contact 11.

In this embodiment, a permanent magnet 12 is disposed below the contact head 7, and the permanent magnet 12 is mounted on the ground and magnetically attracted to the contact head 7.

In this embodiment, the second permanent magnet 13 is arranged at a position corresponding to the second contact 11 in the horizontal direction, and the second permanent magnet 13 is installed on the wall surface and magnetically attracted to the second contact 11.

In this embodiment, pulley 2 is the polyurethane material, and pulley 2's surface has toughness, has reduced the friction with between the floor, effectively reaches the effect of noise reduction.

It is noted that when the slide board 10 slides to the lowermost end, the lower end of the slide board 10 is in contact with the ground.

In addition, the sliding plate 10 and the baffle 3 are both made of light sound insulation materials, namely when the first contact head 7 is not attracted to the first permanent magnet 12, the sliding plate 10 is driven to move to the uppermost end in the second sliding groove 31 under the action of the elastic force of the spring 9.

The working process and principle are as follows: when the utility model is used, firstly, the base 1 is arranged in the mounting hole at the lower end of the door leaf, the permanent magnet I12 is arranged on the floor in the rotation range of the door leaf, the permanent magnet II 13 is arranged on the wall which is rotated to be fully opened and jointed, the door leaf is pushed when ventilation is needed, under the supporting and rolling of the two symmetrically arranged pulleys 2, the phenomenon that the unilateral stress is inclined caused by long-time rotation of the door leaf is avoided, simultaneously, the push-pull force required for opening or closing the door is greatly reduced, the door leaf can be rotated to be in a half-opened state by smaller force, at the moment, the contact head I7 is positioned right above the permanent magnet I12 and finishes suction, the top plate 8 is driven by the slide bar 6 to synchronously move in the process that the contact head I7 moves downwards, and then the slide plate 10 is driven to be drawn out from the slide groove II 31, so that the plane formed by the extended slide plate 10 and the baffle plate 3 seals, the noise generated by flowing through the mounting opening is avoided, when a larger ventilation area is needed, the first contact head 7 is separated from the first permanent magnet 12 only by increasing the thrust, the first contact head 7 and the sliding plate 10 are driven to move upwards synchronously under the elastic action of the spring 9, and the sliding door is continuously pushed until the second contact head 11 at the side end of the baffle 3 is attracted with the second permanent magnet 13, so that the purposes of fully opening and fixing the door leaf are achieved.

Based on the above, the utility model discloses a set up base 1 at the door leaf lower extreme, and set up contact head one 7 below base 1, make it attract with permanent magnet one 12 installed on the floor under the door, realize that the door leaf keeps certain fixed state under the half-open situation, in order to reach the purpose of appropriate ventilation, this attracting state still can drive slide 10 to move down simultaneously, the installation mouth of this door sucking device of shutoff door leaf lower extreme installation, avoid the wind to pass the noise that sends from it; through the pulley 2 that sets up two symmetries in the below at base 1, required push-and-pull power when having reduced greatly and rotating the door leaf, the pulley 2 surface of polyurethane material has toughness, has reduced with the floor between the friction, effectively reaches the effect of noise reduction.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
