Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to detection equipment technical field especially relates to a liner quartz cotton filling tool. BACKGROUND
[0002] In the quantitative detection of factory workshop dust pollution, the liner filled with quartz cotton inhales the air in the workshop according to the flow rate, and the number of dust in unit volume of air is detected by a chromatograph to determine the air dust pollution level of the factory workshop.
[0003] The liner is a transparent glass round pipe structure with double openings. Before the detection process, the glass liner is filled with quartz cotton of a limited length. The existing method is to weigh a certain amount of quartz cotton, manually fill the quartz cotton into the liner with a bamboo stick or a smooth surface stick, and then measure the filling position with a ruler.
[0004] The existing operation method can only fill the quartz cotton and measure with a ruler at the same time. It is not only inconvenient to operate, but also easy to cause filling deviation. When the filling position deviates, the quartz cotton can only be removed and refilled. INVENTION CONTENTS
[0005] The utility model discloses a liner quartz cotton filling tool, which can fill the quartz cotton to the right position at one step and re-fill the quartz cotton through the reverse hook.
[0006] The utility model discloses the technical scheme that adopts:
[0007] A liner quartz cotton filling tool, the liner is a transparent glass round pipe structure with double openings, characterized by comprising a long rod, the length of the long rod is greater than the liner, and the diameter of the long rod is less than the inner diameter of the liner, an elastic retaining ring is sleeved on the long rod, the diameter of the elastic retaining ring is greater than the inner diameter of the liner, the retaining ring and the front end of the long rod determine a predetermined length, and the front end of the long rod is used for extending into the inner hole of the liner so that the quartz cotton filled in the liner is located at the predetermined length position in the liner.
[0008] Further, a length scale is marked on the long rod, and the starting point of the scale is the front end of the long rod.
[0009] Further, a reverse hook is arranged at the rear end of the long rod, the end of the reverse hook is sharp, and the width size of the reverse hook is less than the inner diameter of the liner.
[0010] Further, the reverse hook is arranged at the rear end of the long rod through a fixing structure.
[0011] Further, the reverse hook is integrally formed with the long rod.
[0012] The utility model discloses the beneficial effects are:
[0013] (1) After adjusting the predetermined filling length, the filling was successful in one go;
[0014] (2) The barb is used to correct filling deviations;
[0015] (3) The structure is simple and practical, and the operation is convenient. Attached Figure Description
[0016] Appendix Figure 1 This is a schematic diagram of the structure of this utility model;
[0017] Appendix Figure 2 It is a magnified view of the front end of the long rod;
[0018] Appendix Figure 3 It is a magnified view of a portion of the rear end of the long rod;
[0019] Appendix Figure 4 This is a schematic diagram showing the position of the long rod for filling the liner.
[0020] The labels in the attached diagram are as follows:
[0021] 1. Long rod; 2. Elastic retaining ring;
[0022] 3. Liner; 4. Scale;
[0023] 5. Barb; 6. Sharp point. Detailed Implementation
[0024] The following detailed description of the specific implementation method of the lining quartz wool filling tool of this utility model is provided in conjunction with the accompanying drawings.
[0025] See appendix Figure 1 The quartz wool filling tool for the liner tube 3 is a long rod 1, on which an elastic retaining ring 2 is fitted. The elastic retaining ring 2 is tightened on the long rod 1, defining a position. The position of the elastic retaining ring 2 can be adjusted to change its specific size and position on the long rod 1.
[0026] The front end of the long rod 1 is used to extend into the inner hole of the liner tube 3, so that the quartz wool filled in the liner tube 3 is located at a predetermined length position inside the liner tube 3. Therefore, the length of the long rod 1 is greater than that of the liner tube 3, the diameter is smaller than that of the inner diameter of the liner tube 3, and the diameter of the elastic retaining ring 2 is greater than that of the inner diameter of the liner tube 3.
[0027] See appendix Figure 2 The long rod 1 is marked with a length scale 4, with the starting point of scale 4 being the front end of the long rod 1. The position of the retaining ring 2 is adjusted according to scale 4 so that the length of the long rod 1 inserted into the liner 3 reaches the precise preset value.
[0028] See appendix Figure 3The rear end of the long rod 1 is provided with a barb 5, the end of the barb 5 is sharp, and the width of the barb 5 is smaller than the inner diameter of the liner tube 3. The barb 5 is arranged at the rear end of the long rod 1 through a fixing structure or is integrally formed with the long rod 1. The sharp part 6 of the barb 5 can pull out the quartz wool through the quartz wool layer in the liner tube 3.
[0029] Referring to the drawings Figure 4 During the process of filling the quartz wool in the liner tube 3, the filling position of the quartz wool in the liner tube 3 is determined, the position of the elastic retaining ring 2 on the long rod 1 is adjusted, and the length of the front end of the long rod 1 is the same as the filling length. The worker first clamps a certain amount of quartz wool and sends it into the pipe opening of the liner tube 3, then inserts the front end of the long rod 1 into the pipe opening of the liner tube 3, and slowly pushes the quartz wool forward until the elastic retaining ring 2 contacts the pipe opening of the liner tube 3, the quartz wool has been sent to the filling position, and the filling of the quartz wool in the liner tube 3 is completed.
[0030] When the operation is wrong and the quartz wool filling exceeds the length, the rear end of the long rod 1 is inserted into the liner tube 3, the sharp part 6 of the front end of the barb 5 penetrates the quartz wool, the long rod 1 is pulled back, the barb 5 pulls out the quartz wool from the liner tube 3, and then the filling is re-performed.
[0031] The above is only the preferred embodiment of the present application, and it should be pointed out that, for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
