Description

TECHNICAL FIELD

[0001] The utility model relates to the field of transmission type smoke meter detection technology, and specifically relates to a transmission type smoke meter detection device. BACKGROUND

[0002] The smoke meter is an instrument for measuring the smoke degree of exhaust gas from a vehicle. It is mainly used for measuring the exhaust gas of diesel engines. A piston air pump is used to extract a certain volume of exhaust gas from the exhaust pipe of a diesel engine at a specified time, and the exhaust gas passes through a filter paper of a certain area. The smoke particles in the exhaust gas are trapped on the filter paper and cause the filter paper to turn black. The light absorption rate of the filter paper is measured by a photoelectric measuring device. The light absorption rate represents the size of the smoke degree in the exhaust gas. The non-transparent response time measuring instrument is designed and manufactured to meet the requirements of the measurement circuit response time of the transmission type smoke meter. It can quickly detect the response time of the measurement circuit. The instrument continuously collects the detection signals of the transmission type smoke meter in real time, draws the corresponding data curve of the collected data, and obtains the response time of the measurement circuit, ensuring the authenticity and timeliness of the data. The instrument has multiple communication protocols built-in, which can be used to calibrate transmission type smoke meters from different manufacturers.

[0003] The plug and the socket on the existing detection device body are not provided with a limiting mechanism. When calibrating, the plug may fall off if the staff accidentally pulls it, which may cause the calibration to fail. In addition, the detection device and the display screen are relatively fragile, and may be damaged if they are hit by other objects or fall by themselves. Therefore, technical innovation and design optimization are needed to optimize the transmission type smoke meter detection device. UTILITY MODEL CONTENTS

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] This embodiment describes the specific structure of a transmission-type smoke meter calibration device, which can be referred to in detail below. Figures 1-5 As shown, a transmission-type smoke meter calibration device includes:

[0025] The detection device body 5 is provided with a socket 7 on one side, the plug 4 is inserted into the socket 7, and the tail of the plug 4 is fixed with a connecting line 3 connected with the transmission smoke meter;

[0026] The limiting mechanism is located on the plug 4 and the detection device body 5, and is used for limiting the plug 4.

[0027] At the same time, since the display screen 6 is relatively fragile and may be damaged when impacted by other objects, the display screen 6 is installed on the top of the detection device body 5, a protective cover 1 is hingedly connected to one side of the top of the detection device body 5, and the protective cover 1 can protect the display screen 6 from being damaged by the impact of other objects.

[0028] In addition, when the detection device body 5 is accidentally dropped, the protective legs 2 are fixed at four corners of the detection device body 5, and anti-skid pads are fixed at the bottom of the protective legs 2. The protective legs 2 can buffer the four corners of the detection device when the detection device body 5 falls, so as to avoid damage to the elements in the detection device body 5, and the anti-skid pads can also improve the stability of the detection device.

[0029] At present, the plug 4 and the socket 7 on the detection device body 5 on the market are not provided with a limiting mechanism. When the plug 4 is accidentally pulled by the staff during detection, the plug 4 may fall off, thereby causing detection failure. The limiting mechanism comprises two fixed blocks 8 fixed on the detection device body 5, and a limiting slot 10 and a plug slot 9 are formed in the two fixed blocks 8. The limiting slot 10 and the plug slot 9 are in communication. Fixed plates 11 are fixed on both sides of the plug 4. The fixed plates 11 are provided with plug plates 13. Limiting blocks 14 are fixed on the plug plates 13. Rectangular grooves 18 are formed in the fixed plates 11. Rectangular blocks 16 are slidably arranged in the rectangular grooves 18.

The guide columns 17 penetrate through the rectangular blocks 16. The guide columns 17 and the guide pipes are fixedly connected with the inner walls of the rectangular grooves 18. The springs 15 are sleeved outside the guide columns 17. The springs 15 are in a compressed state. Under the action of the springs 15, the springs 15 drive the rectangular blocks 16 to move, the rectangular blocks 16 drive the plug plates 13 to move, and the plug plates 13 drive the limiting blocks 14 to be inserted into the limiting slot 10, so as to limit the plug 4 and the detection device body 5, and prevent the plug 4 from falling off the detection device body 5.

[0030] When the plug plate 13 needs to be pressed, the press plate 12 is fixed on the side of the plug plate 13 away from the plug 4. The press plate 12 can press the plug plate 13, so that the plug plate 13 drives the limiting block 14 to move out of the limiting slot 10, and the plug 4 and the detection device body 5 are separated.

[0031] It is worth noting that the limiting block 14 is provided with a slope on one side, the limiting block 14 can be inserted into the limiting slot 10, the limiting block 14 is provided with a slope to facilitate the fixed block 8 to extrude the limiting block 14, so that the limiting block 14 can drive the plug plate 13 to move, without pressing the pressing block, the plug 4 can be inserted into the socket 7.

[0032] The detecting device body 5 is a non-light-transmitting response time measuring instrument.

[0033] When the staff needs to measure the non-light-transmitting response time of the transmission smoke meter, the detecting device is first placed on the desktop, the connecting line 3 is connected with the transmission smoke meter, then the plug 4 on the connecting line 3 is aligned with the socket 7 and inserted into the socket 7, when the plug 4 is inserted into the socket 7, the limiting block 14 is extruded by the fixed block 8 to drive the plug plate 13 to move, at the same time, the plug plate 13 extrudes the spring 15 through the rectangular block 16, when the plug plate 13 is completely inserted into the insertion slot 9, under the action of the spring 15, the plug plate 13 drives the limiting block 14 to be inserted into the limiting slot 10, the plug plate 13 drives the limiting block 14 to move out of the limiting slot 10 by pressing the pressing plate 12, so that the plug 4 and the socket 7 can be separated, one hand can be operated, the operation is simple and convenient, and no extra time is wasted.

[0034] Finally, it should be noted that: obviously, the above embodiments are only examples for clearly illustrating the utility model, and are not limited to the implementation mode. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or changes can be made. Here, it is not necessary and impossible to enumerate all the implementation modes. The obvious changes or changes derived therefrom are still within the protection scope of the utility model.
