Description

Technical Field

[0001] The utility model relates to the technical field of alcohol detector equipment, in particular to an infrared alcohol detector. Background Art

[0002] The alcohol detector is an instrument used to detect whether a person has consumed alcohol and the degree of alcohol consumed. It can be used as a detection tool for traffic police to detect how much alcohol a driver has consumed when enforcing the law, so as to effectively reduce the occurrence of major traffic accidents.

[0003] The infrared alcohol detector is developed based on the principle that alcohol-containing body tissue absorbs more light than normal tissue. After infrared rays are shone on human skin, the alcohol content is analyzed based on the degree of reflected infrared rays. This detector takes only 60 seconds from detection to production of results. The infrared radiation beam generated by this infrared alcohol detector can be transmitted through optical fiber into a bracket that can hold a person's forearm. When those suspected of drunk driving put their arms into this bracket, the infrared radiation beam will penetrate his skin and reach about 5 mm below the skin. In order to avoid burning the skin of the person being tested, the infrared radiation beam will move continuously on the surface of his skin. And several infrared sensors will receive the reflected infrared radiation signals. Since the amount of alcohol in the human body is closely related to the absorption of infrared radiation, by observing the spectrum of the reflected infrared radiation, it is possible to know whether the alcohol content in the blood of the person being tested exceeds the standard.

[0004] When using the existing infrared alcohol detector, a person needs to carry a table or a bracket for placing the infrared alcohol detector. When a person suspected of drunk driving has doubts about the test result of the breath alcohol tester, the infrared alcohol detector is used for testing. Since the device is directly placed on the table or the bracket, and since the person suspected of drunk driving is very likely to have drunk alcohol, such person is prone to excessive body movements during the test, causing the device to drop and cause damage. Therefore, an infrared alcohol detector is proposed. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-Figure 4As shown, in this embodiment, an infrared alcohol tester includes an infrared alcohol tester body 1, a box cover 4 and a storage box 6. Four groups of lower folding rods 5 are rotatably connected at the corners inside the storage box 6. The upper parts of the four groups of lower folding rods 5 are rotatably connected to upper folding rods 3 through hinges. The other end of the upper folding rod 3 is connected to the lower end of a fixed frame 2 through a rotating shaft. The infrared alcohol tester body 1 is arranged inside the fixed frame 2. A clamping plate 16 is arranged at the front of the fixed frame 2. A pull rod 10 is fixed to the rear side of the clamping plate 16. The pull rod 10 It extends to the front side of the fixing frame 2, and a spring 17 is mounted on the pull rod 10 between the clamping plate 16 and the fixing frame 2. The two ends of the spring 17 are respectively fixed to the clamping plate 16 and the side of the fixing frame 2. The cross-section of the fixing frame 2 is U-shaped when viewed from the side. Rubber pads 13 are bonded and fixed to the inner rear part of the fixing frame 2 and the rear side of the clamping plate 16. The rubber pads 13 are attached to the front and rear sides of the infrared alcohol detector body 1. The rubber pads 13 can prevent the infrared alcohol detector body 1 from being worn when being clamped.

[0022] like Figure 1 and Figure 3 As shown, the box cover 4 is buckled on the upper part of the storage box 6, a storage bag 11 is fixed on the inner side of the box cover 4, and a non-slip foot pad 7 is fixed at the corner of the lower end of the storage box 6. Handles 8 are movably installed on the left and right sides of the storage box 6 through a rotating shaft. Through the storage bag 11, the unscrewed upper threaded rod 14 and the lower threaded rod 18 can be stored when not in use, and the handle 8 makes it convenient to carry the equipment.

[0023] like Figure 1 and Figure 2 As shown, a lower reinforcing rod 19 is fixed between the two groups of lower folding rods 5 on the left and right sides inside the storage box 6, and a lower threaded rod 18 is threadedly connected to the middle part of the lower reinforcing rod 19, and the lower threaded rod 18 is screwed into the storage box 6. An upper reinforcing rod 15 is fixed between the lower end of the fixed frame 2 and the two groups of upper folding rods 3 on the left and right sides, and an upper threaded rod 14 is threadedly connected to the middle part of the upper reinforcing rod 15, and the upper threaded rod 14 is screwed into the fixed frame 2. The connection strength between the lower folding rod 5 and the upper folding rod 3 on the same side can be improved by the upper reinforcing rod 15 and the lower reinforcing rod 19. The upper folding rod 3 and the lower folding rod 5 can be limited by the upper threaded rod 14 and the lower threaded rod 18 to avoid rotation. At the same time, the fixed frame 2 and the storage box 6 are formed as a whole to improve the stability of the equipment.

[0024] like Figure 1 and Figure 4As shown, a connecting block 12 is fixed to the side surface of one adjacent end of the lower folding rod 5 and the upper folding rod 3, and a thread is processed on the side surface of the connecting block 12. The connecting block 12 is semicircular when viewed from the side in a transverse plane. Nuts 9 are threadedly mounted on the two adjacent groups of connecting blocks 12. The connecting block 12 and the nut 9 can limit the upper folding rod 3 and the lower folding rod 5 after unfolding to avoid folding inward.

[0025] The utility model provides an infrared alcohol tester, and the specific working principle is as follows: during normal use, the box cover 4 is removed, and then the upper threaded rod 14 and the lower threaded rod 18 in the storage bag 11 are removed, and then the fixing frame 2 is moved upward, and the fixing frame 2 drives the upper folding rod 3 to rotate upward, and drives the lower folding rod 5 to unfold until the lower folding rod 5 is perpendicular to the upper folding rod 3, and then the nut 9 is screwed into the connecting block 12, so as to realize the positioning of the upper folding rod 3 and the lower folding rod 5 to avoid folding inward, and then the lower threaded rod 18 can be screwed into the storage box 6 through the lower reinforcing rod 19, and the upper threaded rod 1 4 passes through the upper reinforcing rod 15 and is screwed into the fixing frame 2 to realize the assembly of the equipment. The elastic force of the spring 17 on the clamping plate 16 is used to make the clamping plate 16 tightly fit to the infrared alcohol detector body 1 through the rubber pad 13, so as to clamp the infrared alcohol detector body 1 and avoid accidental contact and falling. The infrared alcohol detector body 1 can be used for detection. When disassembling, the pull rod is pulled forward, the pull rod 10 drives the clamping plate 16 to move, and the spring 17 is squeezed to separate the clamping plate 16 from the infrared alcohol detector body 1, so that the infrared alcohol detector body 1 can be disassembled, which is convenient to use.
