Description

Technical Field

[0001] The utility model relates to the technical field of cigarette detection auxiliary tools, in particular to a ventilation rate calibration piece clamping device for a cigarette comprehensive test bench. Background Art

[0002] As the main measuring instrument in cigarette production sites and laboratories, the benchmark value calibration of each detection functional unit of the cigarette comprehensive test bench is particularly important. At present, the ventilation rate calibration piece in the comprehensive test bench is made of glass fiber. During the calibration process, it needs to be placed in the ventilation rate functional unit as a whole, and the ventilation rate functional unit is calibrated by reading the nominal value of the calibration piece.

[0003] like Figure 1 As shown, the current calibration process is to place the calibration piece 2 at the entrance of the ventilation rate functional unit 1, and let it fall freely into the ventilation rate functional unit 1. After the calibration is completed, the ventilation rate functional unit 1 is turned over to allow the calibration piece 2 to slide out freely. This method has the following problems:

[0004] (1) After the calibration part is placed, it is impossible to determine whether it is placed in place, resulting in inaccurate calibration.

[0005] (2) When the calibration part is placed in the ventilation rate functional unit, it freely falls to the bottom of the ventilation rate functional unit, causing significant wear and tear on the bottom of the calibration part or direct damage.

[0006] (3) The ventilation rate function unit needs to be flipped 180 degrees to remove the calibration part. Often, the operator forgets to remove the calibration part after the calibration is completed, causing the calibration part to be stuck or seriously damaged, resulting in damage to the ventilation rate function unit of the comprehensive test bench.

[0007] Based on this, an auxiliary device is needed during the calibration process to facilitate ventilation rate calibration. Utility Model Content

[0008] In view of the above problems, the utility model provides a ventilation rate calibration piece clamping device for a comprehensive cigarette test bench, which adopts the method of extending and positioning the calibration piece, thereby effectively solving the problems of inaccurate positioning of the calibration piece and inconvenient removal.

[0009] Specifically, the utility model is achieved as follows:

[0010] A cigarette comprehensive test bench ventilation rate calibration piece clamping device, comprising:

[0011] A main body, configured to be adjustable in length;

[0012] A clamping member, disposed at the lower end of the main body, for clamping the calibration member;

[0013] The positioning member is arranged on the main body and its position on the main body is adjustable, and is used to judge the length of the calibration member extending into the ventilation rate functional unit. The bottom surface area of ​​the positioning member is larger than the inlet end surface area of ​​the ventilation rate functional unit.

[0014] Furthermore, the positioning member includes:

[0015] A positioning block is sleeved on the main body;

[0016] The fastener is threadedly connected to the positioning block, passes through the positioning block and abuts against the main body, so as to fix the positioning block on the main body.

[0017] Furthermore, the main body comprises: a plurality of sub-bodies connected end to end, two adjacent sub-bodies are detachably connected, and the clamping member is mounted on the bottommost sub-body.

[0018] Furthermore, the subject comprises:

[0019] Rod sleeve;

[0020] The telescopic rod is arranged in the rod sleeve and is configured to move axially along the rod sleeve.

[0021] Furthermore, a slide rail is provided inside the rod sleeve, and the telescopic rod is installed on the slide rail.

[0022] Furthermore, it also includes:

[0023] An elastic limiting member, comprising a plug-in portion and a limiting pin;

[0024] The bottom of the rod sleeve is provided with a slot and a receiving cavity, and the plug-in portion is adapted to the slot; the telescopic rod is provided with a plurality of limiting holes;

[0025] When the plug-in portion is inserted into the slot, the limiting pin is located in the accommodating cavity and inserted into the limiting hole.

[0026] Furthermore, the clamping piece is an elastic sleeve, and when in use, the elastic sleeve is sleeved on the top of the calibration piece.

[0027] The working principle of this utility model:

[0028] When using, first connect the ventilation rate calibration piece to the main body through the clamping piece, then hold the main body and put the calibration piece into the ventilation rate functional unit. The position of the calibration piece can be roughly determined by the position of the positioning block on the main body. Try to avoid the calibration piece from hitting the bottom of the ventilation rate functional unit when it is put in. After it is completely put in, lock the positioning block and calibrate. After the calibration is completed, hold the main body and take out the calibration piece.

[0029] Compared with the prior art, the utility model has the following beneficial effects:

[0030] (1) The utility model effectively solves the problems that occur during calibration, such as the inability to determine whether the device is properly placed and the device is easily damaged.

DETAILED DESCRIPTION

[0041] The present invention is further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0042] Example 1

[0043] like Figure 2-3As shown, this embodiment provides a cigarette comprehensive test bench ventilation rate calibration piece clamping device, including: a main body 3, a clamping piece 4 and a positioning piece 5, wherein the main body 3 is formed by connecting a plurality of segments of sub-bodies 31 end to end, the sub-bodies 31 are hollow structures, with internal threads at the top and external threads at the bottom, and one or more segments can be used according to actual conditions to adapt to the depth of different comprehensive test bench ventilation rate functional units 1. The clamping piece 4 adopts an elastic sleeve, the top of which is installed on the bottom sub-body 31, and the bottom is used to connect the calibration piece 2, and the calibration piece 2 is fixed by the elasticity of the elastic sleeve, so that the calibration piece 2 can be extended.

[0044] Furthermore, the positioning member 5 is arranged on the main body 3, and includes a positioning block 51 and a fastener 52. The positioning block 51 is sleeved on the main body 3, and the fastener 52 is a bolt, which passes through the positioning block 51 from the side of the main body 3 and abuts against the outer surface of the main body 3, thereby achieving the fixation of the positioning member 5. After loosening the fastener 52, the positioning block 51 can be slid on the main body 3. According to the position of the positioning block 51, the total length of the front end part of the positioning block 51 (part of the main body 1 and the calibration member 2) can be roughly determined, and then the length of the calibration member 2 extending into the ventilation rate functional unit 1 can be roughly determined, and then whether the calibration member 2 is in place can be confirmed. Preferably, a scale can also be set on the surface of the main body 3, and the total length can be more intuitively reflected through the scale.

[0045] Example 2

[0046] like Figure 4-6 As shown, in this embodiment, the main body 3 includes: a rod sleeve 32 and a telescopic rod 33. A slide rail 36 is provided on the inner wall of the rod sleeve 32. The telescopic rod 33 is connected to the slide rail 36 and can slide along the slide rail 36 to adjust the length of the extended rod sleeve 32, thereby adjusting the total length of the main body 3.

[0047] The telescopic rod 33 is fixed by an elastic limit member 35, which is bent as a whole into a spring shape, including an inserting portion 351 and a limit pin 352. A slot and a receiving cavity 37 are provided at the bottom of the rod sleeve 32. A plurality of limit holes 34 are provided on the telescopic rod 33. The inserting portion 351 is adapted to the slot. When the inserting portion 351 is inserted into the slot, the limit pin 352 simultaneously enters the receiving cavity 37. At the same time, the end of the limit pin 352 moves along the surface of the telescopic rod 33. The limit pin 352 is slightly bent toward the inside of the receiving cavity 37 under the extrusion of the telescopic rod 33. After being inserted into place, the limit pin 352 is opposite to the limit hole 34. Under the action of the rebound force, the limit pin 352 is inserted into the limit hole 34, thereby fixing the position of the telescopic rod 33. Then, the length of the main body 3 can be adjusted accordingly according to actual conditions to meet the use requirements.

[0048] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
