Description

Damping swing mechanism for infrared correlation

Technical Field

The utility model relates to an infrared correlation field, concretely relates to swing mechanism that is used for infrared correlation to take damping.

Background

The infrared correlation is called as Active infrared intrusion detectors (Active infrared detectors), and the basic structure of the infrared correlation comprises a transmitting end, a receiving end, a light beam intensity indicator lamp, an optical lens and the like. The detection principle is that infrared rays emitted by an infrared light emitting diode are focused by an optical lens, so that the rays are transmitted to a long distance, and finally the rays are received by a photosensitive transistor at a receiving end. When an object blocks the infrared ray emitted by the emitting end, the receiving end can not receive the infrared ray, so that an alarm can be given. Infrared is an invisible light and is diffused and, after being projected, forms a cone beam in the initial path, the ideal intensity of which decays inversely square with the distance of emission as the distance of emission increases. When the object crosses its detection zone, the infrared beam is intercepted, causing an alarm. But receive site environment's influence sometimes, rotation angle about need adjusting lets infrared correlation more accurate, and above-mentioned adjustment all needs take apart equipment in the inside of infrared mechanism at present, adjusts inside, and is very inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical problem adjust inconvenient problem among the prior art, provide an ability infrared emission or acceptance mechanism's pendulous device from the equipment outside to can realize auto-lock and return to zero.

The utility model adopts the technical proposal that: a damping swing mechanism for infrared correlation comprises a fixing panel for fixing a device wall, wherein the upper end and the lower end of the fixing panel are respectively provided with a lug, a rotating shaft is arranged between the upper lug and the lower lug, the outer side of the rotating shaft is sleeved with a transmitting tube, the transmitting tube is connected with a rear cover, and a cavity formed between the transmitting tube and the rear cover is internally provided with a PCB (printed circuit board); a spring plunger is connected between the fixed panel and the rotating shaft and penetrates through the rotating shaft.

As a further improvement of the utility model, one end of the rotating shaft is provided with a disc. The rotating operation of the rotating shaft is convenient.

As a further improvement of the utility model, the fixing panel is provided with a groove matched with the spring plunger. Thereby make things convenient for the fixed of spring plunger, better provide the damping and feel.

As a further improvement, the spring plunger runs through and the one end of going out is equipped with the bulb, be equipped with the half slot on the launching tube, the ball phase-match of half slot and spring plunger. When the spring plunger rotates to the zero position, the ball head of the spring plunger falls into the semicircular groove, so that a feeling of a hand buckle is provided.

The utility model discloses beneficial effect who has: according to the swing mechanism with the structure, an operator can adjust the infrared receiving and transmitting mechanism without disassembling the equipment, so that the equipment maintenance time and the labor cost are greatly saved. Meanwhile, the design of the spring plunger can provide damping effect for the whole swing mechanism.

Drawings

Fig. 2 is a cross-sectional view of the present invention.

Shown in the figure: the device comprises a rotating shaft 1, a spring plunger 2, a fixing panel 3, a launching tube 4, a rear cover 5 and a PCB 6.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in the figure, a damping swing mechanism for infrared correlation, including pivot 1, spring plunger 2, mounting panel 3, launch canister 4, back lid 5 and PCB board 6, mounting panel is used for fixing whole mechanism to the equipment wall, through controlling the rotatory pivot 1 of gently turning round, can realize launch canister 4 and back lid 5 horizontal rotation, simultaneously under spring plunger 2's effect, realize the damping and feel, spring plunger 2 plays and provides damped effect in mounting panel 3.

Furthermore, in order to facilitate the rotation operation of the rotating shaft, a disc is arranged at one end of the rotating shaft.

Furthermore, the spring plunger is convenient to fix, the damping is better provided, and the fixing panel is provided with a groove matched with the spring plunger.

Furthermore, a semicircular groove is formed in the launching tube 4, and a ball head is arranged at one end, matched with the spring plunger, of the spring plunger; when the spring plunger rotates to the zero position, the ball head of the spring plunger can fall into the semicircular groove, and a hand feeling buckle can be formed, so that the integral zero-returning hand feeling is realized.

According to the swing mechanism with the structure, an operator can adjust the infrared receiving and transmitting mechanism without disassembling the equipment, so that the equipment maintenance time and the labor cost are greatly saved. Meanwhile, the design of the spring plunger can provide damping effect for the whole swing mechanism.
