Description

Technical Field

[0001] This utility model mainly relates to the field of sampler technology, specifically to a vehicle urea detection sampler. Background Technology

[0002] As a key reducing agent in diesel vehicle exhaust aftertreatment systems, the concentration and purity of automotive urea solution directly affect the efficiency of the SCR system. Currently, the industry commonly uses handheld samplers for urea solution quality testing. These samplers typically consist of a sampling tube, a manual suction device, and a storage chamber. While existing samplers offer advantages such as ease of operation and low cost, in practical use, when operators manually insert the sampler into the urea container at different depths, the lack of a vertical guide structure makes the sampling tube prone to tilting. This results in samples taken from different heights at the same depth, affecting the representativeness of the concentration test. Utility Model Content

[0003] 1. The technical problem to be solved by the utility model:

[0004] This utility model provides a vehicle urea detection sampler to solve the technical problems existing in the background art.

[0005] 2. Technical Solution:

[0007] The support frame is symmetrically provided with reference screw holes that communicate with the movable groove on both sides. The outer wall of the cylindrical sampler is provided with several adjusting screw holes equidistantly along the axial direction on both sides. When the reference screw hole is aligned with any adjusting screw hole, it is fixed by locking bolts.

[0008] Furthermore, the bottom end of the first linear guide groove extends to the edge of the outer wall of the cylindrical sampler, while the top end remains closed.

[0009] Furthermore, the top of the support frame is provided with a second guide groove extending horizontally. There are two second guide grooves, which are distributed opposite each other on both sides of the movable groove. A second guide slider is slidably installed in the second guide groove. The second guide slider is threadedly connected to a lead screw, and its bottom is connected to a positioning component through a vertical extension rod.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0027] See attached document Figure 1-5 A vehicle urea testing sampler includes a support frame 1. The top of the support frame 1 is provided with a through movable groove 101. A cylindrical sampler 2 is slidably installed in the movable groove 101. The cylindrical sampler 2 is provided with a matching piston push rod 201 inside. The cylindrical sampler 2 is provided with vertical first linear guide grooves 202 symmetrically arranged on both sides. The inner wall of the movable groove 101 is fixed with a first guide slider 102 that slides in cooperation with the first linear guide groove 202.

[0028] The support frame 1 has symmetrical reference screw holes 103 on both sides that communicate with the movable groove 101. The outer wall of the cylindrical sampler 2 has several adjusting screw holes 203 equidistantly arranged along the axial direction on both sides. When the reference screw hole 103 is aligned with any adjusting screw hole 203, it is fixed by locking bolt 3.

[0029] In this embodiment, the support frame 1 is moved until the cylindrical sampler 2 is vertically above the urea tank. Due to the predetermined relative friction between the piston push rod 201 and the inner wall of the cylindrical sampler 2, after pushing and pulling the piston push rod 201, the cylindrical sampler 2 can be driven to move up and down in the movable groove 101 in conjunction with the sliding cooperation of the first linear guide groove 202 and the first guide slider 102. It is locked by installing locking bolts 3 into the reference screw hole 103 and the aligned adjustment screw hole 203, so that the cylindrical sampler 2 is positioned at different depths in the urea tank. At this time, the piston push rod 201 is pulled again to extract urea solution in the cylindrical sampler 2. The distance between two adjacent adjustment screw holes 203 is fixed, so the sampling depth can be accurately calculated.

[0030] In the above embodiment, the bottom end of the first linear guide groove 202 extends to the outer edge of the cylindrical sampler 2, and the top end remains closed. Therefore, by loosening the locking bolts 3 in the reference screw hole 103 and the alignment adjustment screw hole 203, and pulling the piston push rod 201 upward, the cylindrical sampler 2 can be removed from the movable groove 101 for cleaning and maintenance of its inner wall.

[0031] The top of the support frame 1 is provided with a second guide groove 104 extending horizontally. There are two second guide grooves 104, which are distributed on both sides of the movable groove 101. A second guide slider 4 is slidably installed in the second guide groove 104. The second guide slider 4 is threadedly connected to a lead screw 7, and the bottom is connected to a positioning component 5 through a vertical extension rod 6. The lead screw 7 is rotatably connected to the support frame 1, and one end extends horizontally to the outside of the support frame 1 and is fixed with a rotating handle 701.

[0032] The positioning component 5 includes a movable plate 501. One side of the movable plate 501 is fixedly connected to the vertical extension rod 6, and the other side is close to the cylindrical sampler 2 and has a plurality of evenly distributed guide holes 502. A positioning post 503 is slidably installed in the guide hole 502. One end of the positioning post 503 extends to the outside of the guide hole 502, and the other end is connected to the end of the guide hole 502 by a spring 504.

[0033] In this embodiment, after the rotating handle 701 drives the lead screw 7 to rotate, the second guide slider 4 can be driven to slide in the second guide groove 104. The vertical extension rod 6 drives the movable plate 501 to move synchronously. Similarly, the movable plate 501 on the other side moves relative to each other. After the positioning pin 503 abuts against the outer surface of the urea barrel, according to the curvature of the outer surface of the urea barrel, the positioning pin 503 at different positions will slide a different distance in its corresponding guide hole 502 and squeeze the spring 504, so as to fit as close as possible to the outer surface of the urea barrel and achieve the effect of clamping and positioning.

[0034] The bottom of the support frame 1 is provided with a fixing sleeve 8, which is aligned with the movable groove 101, and the inner wall is attached with a wiping cloth roll 9 by Velcro.

[0035] In this embodiment, when the cylindrical sampler 2 rises after sampling, the wiping cloth roll 9 can wipe off the urea solution on its surface, and the wiping cloth roll 9 is attached to the inner wall of the fixing sleeve 8 by Velcro for easy cleaning and replacement.

[0036] In the above embodiments, in order to prevent the urea solution wiped off by the wiping cloth roll 9 from falling into the urea bucket and causing pollution, the cylindrical sampler 2 samples from shallow to deep in sequence during sampling, and moves away from the urea bucket after sampling to avoid pollution.

[0037] The support frame 1 is fixedly mounted with a base 10, and the bottom of the base 10 is equipped with self-locking casters 11, which facilitates the movement of the entire device.

[0038] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.

[0039] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art.
