Include any and all combinations of one or more related listed items.
As shown in Figure 1, a kind of short stroke bullet door device, the cavity 2 including hollow structure, one end is equipped with stage portion in cavity 2
21,21 medial surface of stage portion is equipped with the push rod 1 abutted, and described 1 one end of push rod extends to outside cavity 2,1 other end of push rod according to
Secondary to be equipped with elastic component 4 and end cap 5, the side of the end cap 5 is equipped with opening, and opening is connect by screw thread with cavity 2, elastic component
4 both ends are abutted with push rod 1 and 5 bottom of end cap respectively.It is equipped with fixed ring 23 in the lateral surface of 2 push rod end of cavity, outside the cavity 2
Side is connected through a screw thread equipped with casing 3, and 3 length of described sleeve pipe is not less than 2 length of cavity, is equipped with 4 in the lateral surface of fixed ring 23
A threaded hole 22 is uniformly distributed centered on 23 center of circle of fixed ring, when bullet door device is fixed, 23 medial surface of fixed ring and doorframe
The through-hole lateral surface that is equipped with abuts, and casing 3 is in doorframe, by the screw thread between casing 3 and cavity 13 by casing 3 and cavity
13 fixed rings 23 are separately fixed at the medial surface and lateral surface of doorframe side panel, so as to which cavity 13 is fixed, this
When, only push rod 1 is higher than doorframe side, and other structures are hidden in inside doorframe, increases whole aesthetics.
Wherein, push rod 1 includes sliding bottom 13, interconnecting piece 12, contact portion 11, and sliding bottom 13 and interconnecting piece 12 are fixed
Connection, sliding bottom 13 slide between the stage portion 21 in cavity 13 and elastic component 4, through-hole of the interconnecting piece 12 in stage portion 21
The outer end of middle sliding, interconnecting piece 12 is equipped with contact portion 11, and further, contact portion 11 is nylon, uses PA66 in the present embodiment,
Contact portion 11 has certain hardness at this time, is unlikely to deform during pushing the door open, further, the lateral surface of contact portion 11
It can be rounded corner equipped with chamfering, or common chamfering, in the present embodiment, using rounded corner, contact portion 11 is outer at this time
There is certain radian will not scrape, can damage to avoid body on the door with door body contact process for side, into
One step, the diameter of sliding bottom 13 is less than 13 hollow portion internal diameter 0.2-2mm of cavity, in the present embodiment, 13 diameter of sliding bottom
Less than 13 hollow portion internal diameter 0.5mm of cavity, at this point it is possible to avoid push rod 1 after being compressed, sliding bottom 13 is in cavity 13
Angle offset occurs for portion, during avoiding the contact portion 11 at 1 top of push rod from stretching out in the through-hole from 13 stage portion 21 of cavity
It collides, increases the stationarity that push rod 1 moves, further, when elastic component 4 is compressed into the most loss of quantity, elastic component 4 is far from end
5 side of lid is not less than the length of cavity 13 to the distance of 13 through-hole lateral surface of cavity, at this point, in door closing procedure and after closing the door,
Push rod 1 whole can be placed in the hollow structure of cavity 13, will not influence the closing of door body.
Specifically, push rod 1 is socketed in cavity 13, the contact portion 11 of push rod 1 is stretched out from the through-hole of stage portion 21,
Elastic component 4 is equipped in cavity 13, one end of elastic component 4 is abutted with the medial surface of 1 sliding bottom 13 of push rod, then by end cap 5 and chamber
13 other end of body is connected through a screw thread fixation, adjusts the position of end cap 5, compresses elastic component 4, at this point, push rod 1 is after being compressed
It being capable of automatic spring under the action of elastic component 4.
The face contacted on doorframe with door body opens up a through-hole, by after assembling push rod 1, cavity 13, elastic component 4 with
And the installation of end cap 5 is in through-holes, at this point, fixed ring 23 is located at doorframe open outer side, other structures are located on the inside of doorframe, in screw thread
Package assembly is fixed by fastener at hole 22, on the inside of doorframe, sleeve and cavity 13 are connected through a screw thread fixation, sleeve
It is abutted after fixation with the side of doorframe, using welding or fixed glue fixes sleeve and doorframe medial surface, due to after mounting,
With needing to be filled up with sealant in doorframe, at this point, sealant will not penetrate into sleeve inner, the operation of push rod 1 will not influence, this
When sealant sleeve can be also fixed.
After fixation, no matter whether door body closes, and elastic component 4 acts on the sliding bottom 13 of push rod 1, i.e. push rod always
1 is in confined state always, and when door is closed, door body side is contacted with the contact portion 11 of push rod 1, and elastic component 4 is pressed
Contracting, push rod 1 completely into cavity 13 inside, at this point, bullet door device will not influence the closing of door body, when opening the door, when opening door lock
Afterwards, since elastic component 4 is constantly in confined state, at this point, elastic component 4 acts on push rod 1, due at the door lock of door body
It opens, one side position of door lock is not fixed, and push rod 1 will stretch out under the action of elastic component 4, door be flicked, to complete
The process of automatic door opening.
For the door body of different model, weight may be different, at this point, cavity 13 is back-outed out of doorframe, then adjust
The different elastic component 4 of positional relationship or replacement between whole end cap 5 and cavity 13, to obtain different degrees of compressed elastic component
4 and different thrust sizes push rod 1.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
