The door bottom self-sealing device is characterized in that a plate-shaped spring sheet is arranged between one end of the ejector rod and the other end of the base, and the sealing bar is detachably connected on the spring sheet. The door bottom self-sealing device is arranged on the bottom of a door and automatically makes the sealing bar to stretch out through the ejector rod after the door is closed, and therefore a clearance between the door bottom and a ground is sealed and air circulation is prevented. In addition, the door bottom self-sealing device has the advantages of being few in parts, convenient to mount, adjustable and the like.
Description
Technical field
The utility model relates to a kind of section bar, in particular for the device capable of automatically sealing bottom of door of clean room.
Background technology
Places such as hospital, Electronics Factory, laboratory have high-grade dustless clean room usually.Clean room is very high to the requirement of cleaning, and it forms structure all can reduce laying dust through particular design with convenient for cleaning as far as possible.Air is the media that dust enters clean room, especially through move into one's husband's household upon marriage and doorframe, ground between the slit come in without the air that purifies, it is an important dust source.How to guarantee the sealing of door, the inside and outside circulation of air of isolated clean room is an important behave that improves cleanliness factor in the clean room as far as possible.The sealing of opposite house, its difficult point is the sealing on opposite house and ground.Because door needs frequent switching, must maintain a certain distance between the door end and the ground, in order to avoid frictional force is too big.Utilization arranges the weather strip of a rubber at the bottom of door, closely contact with ground, thereby to carry out good sealing be a good solution closing behind the door opposite house.But in the process of switch door, frequent friction can be accelerated the aging and wearing and tearing of rubber; In addition, also the dust on ground can have been swept, thereby increase the weight of contamination by dust.How to solve this phenomenon, what will take into account installation simultaneously conveniently is the technical problems to be solved in the utility model.
Summary of the invention
In order to overcome this problem, the utility model provides a kind of device capable of automatically sealing bottom of door simple in structure, easy for installation.
The technical solution of the utility model provides a kind of device capable of automatically sealing bottom of door, it comprises that cross section is the base of the lengthwise of U font, be movably set with the weather strip of lengthwise in the U-lag of described base, described base is provided with chute along described base length direction, be provided with push rod in the described chute movably, one end of described push rod stretches out outside the described base, it is characterized in that: be provided with plate shape spring leaf between an end of described push rod and the other end of described base, described weather strip removably is connected on the described spring leaf.
Preferably, described push rod threaded one end connects adjusting nut, and described spring leaf one end is connected on the described adjusting nut.
Preferably, the free end of described spring leaf is provided with the fixed bar of rod, and described fixed bar is arranged in the described chute movably.
Preferably, described spring leaf is connected with described fixed bar and described push rod hinge.
Preferably, two of described base free end tops are provided with the limiting section of bending to the inside.
Preferably, be provided with stage clip between described push rod and the described base, described compression spring sleeve is on described push rod.
Preferably, described weather strip comprises fixed part and the strip rubber strip of inlay card in described fixed part of U font.
A kind of device capable of automatically sealing bottom of door of the present utility model is arranged on the bottom of door, and it automatically weather strip is stretched out after door is closed, thereby the slit at the bottom of the opposite house and between the ground seals by push rod, stops circulation of air.In addition, it is few, easy for installation that a kind of device capable of automatically sealing bottom of door of the present utility model has a part, advantage such as can regulate.
Description of drawings
Fig. 1 is the structural representation of a kind of device capable of automatically sealing bottom of door of the present utility model;
Fig. 2 is the structural representation of the cross section of Fig. 1;
Fig. 3 is the assembly structure schematic diagram of push rod and adjusting nut.
The specific embodiment
Below the specific embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of device capable of automatically sealing bottom of door of the present utility model comprises base 10 and weather strip 12.Wherein, the cross section of base 10 is the U font, closed at both ends; Inlay card is in the U-lag of base 10 versatilely for weather strip 12, and weather strip 12 comprises fixed part 14 and the strip rubber strip 16 of inlay card in fixed part 14 of U font, and rubber strip 16 reaches outside the base 10 from the opening of base 10.Two free end tops bending to the inside of base 10 forms limiting section 18, and the distance between the limiting section 18 is slightly less than the fixed part 14 of weather strip 12, thereby avoids weather strip 12 to come off from the opening of base 10.Be provided with chute 20 near its bottom along its length direction in the base 10, the rib 22 that protrudes in the inwall of chute 20 by base 10 both sides is formed.Be provided with push rod 24 in the chute 20 movably, outside the end protuberate basic unit 10 of push rod 24.The fixed bar 28 of spring leaf 26, the one end articulated mast shapes of one plate shape, other end hinge connects push rod 24, and this fixed bar 28 also is arranged in the chute 20 of base 10; Under the normality, spring leaf 26 bends, and forms the elastic force of stretching to two ends.The middle part of weather strip 12 is fixed on the spring leaf 26 by screw.
Further, can also between push rod 24 and base 10, be provided with the stage clip 30 that is enclosed within on the push rod 24, make the elastic force that push rod 24 resets with increase.
A kind of device capable of automatically sealing bottom of door of the present utility model is in when assembling, by screw base 10 is fixed to the bottom of door (not shown) at first earlier, and the two ends with spring leaf 26 connect with push rod 24, fixed bar 28 respectively then; Secondly weather strip 12 is fixed on the spring leaf 26 by screw or screw.Again the end of combinations thereof part from base 10 inserted, make rubber strip 16 stretch out from the opening of base 10.With the closed at both ends of base 10, wherein the part of push rod 24 is exposed outside the base 10, namely finishes whole assembling process at last.Compared to other structures, part of the present utility model is few, and assembling is simple.
During use, when door is closed, doorframe extruding push rod 24, thus make spring leaf 26 bendings make rubber strip 16 move down by push rod 24, thereby with the gap closing between door and the ground.After door was opened, under the elastic force effect of spring leaf 26, push rod 24 is mobile resetting outwards, and rubber strip 16 reclaims.
Further, the utility model can also arrange screw thread at push rod 24 as shown in Figure 3, and the adjusting nut 32 that is threaded, and an end of spring leaf 26 fixes on the adjusting nut 32 by hinges fixing.So just can regulate the length outside push rod 24 protuberate basic units 10, thereby regulate the distance that rubber strip 16 stretches out by rotation push rod 24.
Above embodiment only is the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
