Abstract
The utility model discloses a one-way door which comprises a rotating shaft, a ratchet wheel mechanism, a fixed block, a first connecting rod, a second connecting rod, a limited rod and a semicircular partition plate, wherein the ratchet wheel mechanism is connected and concentric with the lower end of the rotating shaft, the fixed block is connected and concentric with the upper end of the rotating shaft, the first connecting rod is arranged on the rotating shaft, the second connecting rod is arranged on the rotating shaft, the first and second connecting rods are equal in height, a 90-degree angle is formed between the first and second connecting rods, the limited rod is intersected and matched with the first connecting rod or the second connecting rod, a certain gap is formed between an arc surface formed by the rotation of the connecting rods and the semicircular partition plate, and the ratchet wheel mechanism just rotates counterclockwise. The principle of the one-way door disclosed by the utility model is as follows: the rotating shaft is controlled to rotate reversely by using the one-way motion of the ratchet wheel mechanism, and through cooperating with the limited rod, the purpose of one-way entrance is achieved; and the one-way door has the advantages of simple structure, low manufacture cost and one-way passing.
Description
Technical field
The utility model relates to a kind of unilateral gate.
Background technology
Existing revolving door generally is made up of the revolving door leaf of centre and the tabular door leaf of sealing all around, and existence can not be used as the defective of half-duplex channel, and needs the professional to guard.
Summary of the invention
The utility model technical problem to be solved provides a kind of one-way movement that utilizes ratchet mechanism, the control rotating shaft backwards rotation, and cooperate gag lever post, realize the unilateral gate of the purpose of unidirectional entering.
The utility model is realized through following technical scheme: a kind of unilateral gate; Comprise rotating shaft, reach and rotating shaft lower ends and concentric ratchet mechanism, and link to each other and concentric fixed block with the rotating shaft upper end; And be arranged on the head rod in the rotating shaft; And be arranged in the rotating shaft and with height such as head rod grade, and form 90 ° second connecting rod, and intersect the gag lever post that cooperates with the head rod or second connecting rod; And with the be separated by semicircular dividing plate of certain interval of the cambered surface that connecting rod rotation forms, described ratchet mechanism only allows to rotate counterclockwise.
As preferably, said head rod is identical with the second connecting rod structure, all separated by a distance being fixedly connected in the rotating shaft, and all have the gap with the gag lever post bottom.
As preferably, said gag lever post and rotating shaft have the gap, and become pectination.
The beneficial effect of the utility model is: utilize the one-way movement of ratchet mechanism, and the control rotating shaft backwards rotation, and cooperate gag lever post, and realize the purpose of unidirectional entering, it has simple in structure, low cost of manufacture, the advantage of one-way trip.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the front view of the unilateral gate of the utility model;
Fig. 2 is the vertical view of the unilateral gate of the utility model.
The specific embodiment
As depicted in figs. 1 and 2, a kind of unilateral gate of the utility model comprises rotating shaft 1; Reach and rotating shaft 1 lower ends and concentric ratchet mechanism 2, the direction of motion of control rotating shaft 1, and link to each other and concentric fixed block 3 with rotating shaft 1 upper end; And be arranged on the head rod 4 in the rotating shaft 1, and be arranged in the rotating shaft 1 and with head rod 4 height such as grade, and form 90 ° second connecting rod 5; And intersects the gag lever post 6 that cooperates with the head rod 4 or second connecting rod 5, the purpose of real one-way trip, and and the be separated by semicircular dividing plate 7 of certain interval of the connecting rod cambered surface of rotating formation; Improve the function of one-way trip, 2 of described ratchet mechanisms allow to rotate counterclockwise.
Wherein, said head rod 4 is identical with second connecting rod, 5 structures, all separated by a distance being fixedly connected in the rotating shaft 1, and all have the gap with gag lever post 6 bottoms; Said gag lever post 6 has the gap with rotating shaft 1, and becomes pectination.
The beneficial effect of the utility model is: utilize the one-way movement of ratchet mechanism, and the control rotating shaft backwards rotation, and cooperate gag lever post, and realize the purpose of unidirectional entering, it has simple in structure, low cost of manufacture, the advantage of one-way trip.
The above is merely the specific embodiment of the utility model, but the protection domain of the utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.
Claims (3)
