Description

Technical Field

[0001] This utility model relates to the field of recycled polyester fiber testing technology, and more specifically, to a portable testing device for recycled polyester fibers. Background Technology

[0002] Polyester fiber (polyester) is a widely used synthetic fiber, and its recycling has become an important direction in the field of environmental protection. Recycled polyester fiber and virgin polyester fiber are very similar in appearance and cannot be accurately distinguished by the naked eye. It is necessary to use professional testing equipment to analyze their spectral characteristics, molecular structure, etc., in order to achieve accurate identification.

[0003] Currently, the connection structure between the probe and the main body of the existing recycled polyester fiber detection equipment is not stable enough. Frequent disassembly and replacement can easily lead to loose threads and damage, resulting in a shortened service life of the equipment and increased operating costs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a portable testing device for recycled polyester fibers, reducing the need for replacement parts and increasing service life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable detection device for recycled polyester fiber, comprising a detector body, wherein the detector body is equipped with a probe interface, the probe interface comprising two symmetrically arranged sleeve portions, one sleeve portion being inserted into the detector body and the other sleeve portion extending out of the detector body, the sleeve portion being used to install a probe, and the probe being threadedly connected to the sleeve portion.

[0006] Furthermore, the probe interface also includes a fixing part located between the two sockets, which is detachably connected to the detector body.

[0007] Furthermore, the fixing part is detachably connected to the detector body via fasteners.

[0008] Furthermore, the fixing part includes a through hole and a fourth countersunk hole located at both ends of the through hole in the axial direction. The fourth countersunk hole is used to install fasteners. The fasteners pass through the fourth countersunk hole and the through hole and are threaded into the detector body.

[0009] Furthermore, the detector body is provided with a third countersunk hole and a mounting hole, with the fixing part inserted into the third countersunk hole and the sleeve part inserted into the mounting hole.

[0010] Furthermore, the socket includes a threaded portion, which is inserted into the probe and threadedly connected to the probe.

[0011] Furthermore, the socket includes a first annular groove located on the side of the socket near another socket, and a first washer is installed in the first annular groove. The outer diameter of the first washer is larger than the outer diameter of the socket. The probe includes an extension, and the extension is provided with a second annular groove, into which the outer periphery of the first washer is inserted.

[0012] Furthermore, the inner diameter of the extension is larger than the inner diameter of the probe.

[0013] Furthermore, a second washer is installed between the fixing part and the probe.

[0014] In summary, this utility model has the following beneficial effects:

[0015] The probe interface adopts a dual-sleeve design, with both sleeves capable of connecting the probe. If the threads of one sleeve become loose or damaged, it can be switched to the other sleeve, reducing the frequency of parts replacement. At the same time, the first washer and the second annular groove cooperate, and the buffering effect of the second washer not only achieves sealing and reduces environmental interference, but also prevents the probe from being over-tightened, which could damage the threads and further extend the service life of the equipment and the probe.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3As shown, this embodiment provides a portable detection device for recycled polyester fibers, including a detector body 1, which is a portable Raman spectrometer. The detector body 1 is made of lightweight material, is small in size and light in weight, and is easy to carry. It integrates core components such as detection circuit, display module, and power supply module to realize the detection of recycled polyester fibers and display the detection results. The power supply module can use a rechargeable battery to further improve portability.

[0022] like Figure 1 , Figure 2 As shown, the detector body 1 is equipped with a probe interface 2, which is used to connect probes 6. There are multiple probes 6 with different lengths. In the face of interference from different fabrics, colors, thicknesses and materials, the corresponding probes (with different focusing distances) must be replaced in order to measure the effective spectrum, avoid misjudgment, and measure the difference between recycled polyester fibers and virgin polyester fibers.

[0023] The function of probe 6 is to isolate ambient light to reduce detection errors. The light emitted from the detector body 1 passes through probe 6 and hits the object to be tested for spectral detection.

[0024] Probe interface 2 is used for fixing and installing probe 6, such as Figure 2 As shown, the probe interface 2 includes two symmetrically arranged sockets 22, which are integrally formed. One socket 22 is inserted into the detector body 1, and the other socket 22 extends out of the detector body 1 for mounting the probe 6. The probe 6 is threadedly connected to the socket 22, which facilitates the quick installation and removal of the probe 6.

[0025] The probe interface 2 also includes a fixing part 21 located between the two socket parts 22. The fixing part 21 is integrally formed with the two socket parts 22. The fixing part 21 is detachably connected to the detector body 1, which facilitates the overall disassembly, maintenance and replacement of the probe interface 2. Specifically, the fixing part 21 is detachably connected to the detector body 1 by fasteners 3. The fasteners 3 can be common connecting parts such as bolts and screws, which have a simple structure, reliable connection and convenient disassembly.

[0026] The fixing part 21 includes a through hole 212 and fourth countersunk holes 211 located at both ends of the through hole 212 along its axial direction. The inner diameter of the fourth countersunk holes 211 is larger than the inner diameter of the through hole 212. The fourth countersunk holes 211 are used to install fasteners 3, so that the head of the fasteners 3 can be inserted into the fourth countersunk holes 211. The fasteners 3 pass through the fourth countersunk holes 211 and the through hole 212 and are threadedly inserted into the detector body 1, thereby achieving a firm connection between the fixing part 21 and the detector body 1.

[0027] The detector body 1 is provided with a third countersunk hole 14 and a mounting hole 11. The size of the third countersunk hole 14 is adapted to the size of the fixing part 21. The fixing part 21 is inserted into the third countersunk hole 14 to realize the positioning and limiting of the fixing part 21 and prevent the fixing part 21 from shifting. The size of the mounting hole 11 is adapted to the size of the sleeve part 22. The sleeve part 22 inserted into the detector body 1 is inserted into the mounting hole 11.

[0028] The detector body 1 is also provided with a first countersunk hole 12 and a second countersunk hole 13, which are used to accommodate the second washer 5 and the first washer 4, respectively.

[0029] The socket 22 includes a threaded portion 222, which is located at the end of the socket 22. The probe 6 has an internal thread that is compatible with the threaded portion 222. The threaded portion 222 is inserted into the probe 6 and threadedly connected to the probe 6, thereby achieving a firm connection between the probe 6 and the socket 22, and facilitating disassembly and replacement.

[0030] To ensure stable detection results, probe 6 needs to be tightened onto the socket 22. However, probe 6 requires frequent disassembly and replacement, making its threads prone to loosening or damage. By providing sockets 22 at both ends, both sockets 22 can be used. When one socket 22 becomes loose or damaged, the other socket 22 can be replaced, extending the equipment's lifespan. Although probe 6 also wears down, it can still function normally for a period of time when paired with a new socket 22. This significantly reduces the frequency of parts replacement.

[0031] like Figure 2 As shown, the socket 22 includes a first annular groove 221, which is located on the side of the socket 22 closest to the other socket 22, i.e., close to the fixing part 21. A first washer 4 is installed in the first annular groove 221. The first washer 4 can be made of a material with elasticity and sealing properties, such as a rubber washer or a silicone washer. The outer diameter of the first washer 4 is larger than the outer diameter of the socket 22. The probe 6 includes an extension 61, which is integrally formed with the probe 6. The inner diameter of the extension 61 is larger than the inner diameter of the probe 6. The inner wall of the extension 61 is provided with a second annular groove 611. When the probe 6 is threadedly connected to the socket 22, the outer periphery of the first washer 4 is inserted into the second annular groove 611 to achieve a sealing and buffering effect. Meanwhile, a second washer 5 is installed between the fixing part 21 and the probe 6. The second washer 5 can also be made of materials such as rubber or silicone. It is fitted onto the sleeve part 22 extending from the detector body 1, located between the fixing part 21 and the extension part 61 of the probe 6, to facilitate the tightening of the probe 6. The elastic buffer helps to prevent the probe 6 from being tightened too much, which would increase the risk of thread damage. Furthermore, the first washer 4 provides axial restraint for the probe 6, which helps to stabilize the axial position of the probe 6.

[0032] When the probe 6 is threadedly connected to the sleeve 22, the resistance to turning the probe 6 increases when the extension 61 first touches the first washer 4. As the probe 6 continues to be screwed in, the resistance to turning the probe 6 decreases when the first washer 4 just fits into the second annular groove 611. This is the appropriate depth for turning the probe 6. In this state, the extension 61 lightly presses the second washer 5. The operator can turn the probe 6 to this position by sensing the turning resistance to prevent over-tightening from damaging the threads.

[0033] The outer diameter of the first washer 4 is 0.2mm-0.3mm larger than the inner diameter of the extension 61 to prevent the first washer 4 from being over-compressed and increasing the risk of damage. As a vulnerable part, the replacement cost of the first washer 4 is much lower than that of the probe 6.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
