Description
Technical Field
[0001] This utility model relates to the field of measuring instrument storage technology, and more specifically, to a portable thermoluminescent dosimeter. Background Technology
[0002] A thermoluminescent dosimeter is a device used to measure ionizing radiation dose. Through encapsulation, filters, and labeling systems, it ensures accurate radiation dose measurement and data traceability, and is widely used in medical, nuclear industry, and environmental monitoring fields. Existing thermoluminescent dosimeters are mainly divided into two types: personal dosimeters and environmental dosimeters. Environmental dosimeters have a larger main structure and usually require a carrying case or other auxiliary structure for easy transport by the user when taken to the measurement environment.
[0003] However, when using a traditional thermoluminescent dosimeter, the user usually needs to open the lid of the suitcase first before taking out the dosimeter. Existing suitcases designed for dosimeters usually have shock-resistant structures inside to prevent the dosimeter from shaking during transport, which means that the user needs to separate the shock-resistant structure from the dosimeter before they can take it out properly, which has certain limitations. Utility Model Content
[0004] This invention provides a portable thermoluminescent dosimeter, which solves the problems in the background art mentioned above, namely:
[0005] Traditional dosimeters are usually connected to the shock-resistant structure of the external casing when carried, and users need to separate the shock-resistant structure from the dosimeter before they need to take it out, which has certain limitations.
[0006] To achieve the above objectives, the portable thermoluminescent dosimeter includes an outer casing and a measuring instrument body. The outer casing is provided with a sliding pull mechanism, which includes a sliding cover that is slidably disposed on one side of the outer casing. The sliding cover is fixedly disposed with the measuring instrument body, and the sliding pull mechanism removes the measuring instrument body entirely from the outer casing through the sliding cover.
[0007] Both sides of the sliding cover are fixedly connected to sliders, and both sides of the outer box are provided with sliding grooves. The sliders are slidably connected to the sliding grooves. A buckle is fixedly provided at the connection between the slider and the outer box. The sliding cover is detachably connected to the outer box through the buckle. At least two No. 1 fixing bolts are threadedly connected to one side of the sliding cover. The sliding cover is fixedly connected to the measuring instrument body through the No. 1 fixing bolts.
[0008] In the above technical solution, the measuring instrument body can be quickly picked up and put away through the sliding pull mechanism. The sliding cover and the measuring instrument body are fixedly connected by the No. 1 fixing bolt. With the sliding cooperation of the slider and the slide groove, combined with the detachable connection of the buckle, the user only needs to open the buckle and pull the sliding cover to pull the measuring instrument body out of the outer box.
[0009] Based on this, the outer casing is also equipped with a motion limiting mechanism, which is used to maintain the stability of the measuring instrument body during carrying. Mounting slots are provided at each of the four corners of one side of the outer casing. The motion limiting mechanism includes four telescopic rods that are slidably connected inside the four mounting slots, and each of the four telescopic rods is fixedly connected to one side of the sliding cover. Four No. 2 fixing bolts are threaded through the outer casing on the side away from the sliding cover. These No. 2 fixing bolts are used to fix one end of the telescopic rod in the mounting slot. One end of the telescopic rod has a threaded groove, and the No. 2 fixing bolt is threadedly connected to the threaded groove.
[0010] In another technical solution, by sliding the four telescopic rods to the mounting groove and fixing the ends of the telescopic rods with the No. 2 fixing bolt, the measuring instrument body remains connected to the outer box after being pulled out, and can be used flat without complete separation. The outer box and the bottom surface of the sliding cover form a stable support, further optimizing the stability and maintenance convenience of the device.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. In this portable thermoluminescent dosimeter, a sliding pull mechanism enables quick loading and unloading of the instrument body. The sliding cover is fixedly connected to the instrument body by a No. 1 fixing bolt, and with the sliding cooperation of the slider and the slide groove, combined with the detachable connection of the buckle, the user only needs to open the buckle and pull the sliding cover to pull the entire instrument body out of the outer box. This eliminates the cumbersome steps of separating the shock-resistant structure required by traditional instruments, greatly simplifying the operation process. At the same time, the sliding pull mechanism itself also has a limiting function, ensuring the relative stability of the instrument body and the outer box during carrying and avoiding the risk of shaking.
[0013] 2. In this portable thermoluminescent dosimeter, the four telescopic rods are slidably connected to the mounting groove, and the ends of the telescopic rods are fixed and restricted by the No. 2 fixing bolt. After the measuring instrument body is pulled out, it remains connected to the outer box and can be used flat without being completely separated. The outer box and the bottom surface of the sliding cover form a stable support, which further optimizes the stability and maintenance convenience of the device and improves the safety during use.

[0023] 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.
[0024] Currently, traditional dosimeters are typically connected to an external shock-resistant casing when carried, requiring the user to detach the casing before removing the dosimeter, which presents certain limitations. This invention provides a portable thermoluminescent dosimeter. (See [reference]) Figure 1 - Figure 3 As shown, it includes an outer box 1 and a measuring instrument body 2. The outer box 1 is provided with a sliding pull mechanism 3. The sliding pull mechanism 3 includes a sliding cover 31 that is slidably disposed on one side of the outer box 1. The sliding cover 31 is fixedly disposed with the measuring instrument body 2. The sliding pull mechanism 3 removes the measuring instrument body 2 entirely from the outer box 1 through the sliding cover 31.
[0025] In practice, sliders 32 are fixedly connected to both sides of the sliding cover 31, and grooves 11 are opened on both sides of the outer box 1. The sliders 32 are slidably connected to the grooves 11. A buckle 33 is fixedly provided at the connection between the slider 32 and the outer box 1. The sliding cover 31 is detachably connected to the outer box 1 through the buckle 33. At least two No. 1 fixing bolts 311 are threadedly connected to one side of the sliding cover 31. The sliding cover 31 is fixedly connected to the measuring instrument body 2 through the No. 1 fixing bolts 311.
[0026] Specifically, a handle is provided on one side of the sliding cover 31. When the user needs to take out the measuring instrument body 2, he / she needs to open the buckle 33 first, and then directly pull the sliding cover 31 and the measuring instrument body 2 out to the outside of the outer box 1 through the handle. Similarly, when retracting the measuring instrument body 2, the user pushes the sliding cover 31 towards the outer box 1 and re-secures the buckle 33. This simplifies the steps of taking out and putting in the measuring instrument body 2 and effectively solves the problem that traditional instruments need to be separated from the shock-resistant structure before taking out and putting in.
[0027] Furthermore, the sliding pull mechanism 3 also serves to limit the shock absorption of the measuring instrument body 2. The first fixing bolt 311 can firmly fix the measuring instrument body 2 onto the sliding cover 31. When the sliding cover 31 is installed, it is kept stable by the limiting effect of the sliding groove 11 on the slider 32 and the detachable connection of the buckle 33, so as to prevent the measuring instrument body 2 from shaking inside the outer box 1 during the carrying process.
[0028] In addition, see Figure 4 As shown, the outer casing 1 is also equipped with a motion limiting mechanism 4, which is used to maintain the stability of the measuring instrument body 2 during carrying.
[0029] The outer casing 1 has four mounting slots 12 at each of its four corners. The motion limiting mechanism 4 includes four telescopic rods 41 that are slidably connected inside the four mounting slots 12. The four telescopic rods 41 are fixedly connected to one side of the sliding cover 31. The outer casing 1 is threaded with four No. 2 fixing bolts 43 on the side away from the sliding cover 31. The No. 2 fixing bolts 43 are used to fix one end of the telescopic rod 41 in the mounting slot 12. One end of the telescopic rod 41 has a threaded groove 42, and the No. 2 fixing bolt 43 is threadedly connected to the threaded groove 42.
[0030] The extension and retraction of the four telescopic rods 41 within the mounting groove 12, along with the limiting of the slider 32 by the sliding groove 11 during the sliding process, makes the process of pulling the sliding cover 31 and the measuring instrument body 2 out of the outer box 1 more stable, and avoids collisions between the measuring instrument body 2 and the outer box 1 during the pulling process.
[0031] Furthermore, by fixing one end of the telescopic rod 41 with the second fixing bolt 43, the measuring instrument body 2 and the sliding cover 31 remain connected to the outer casing 1 after being pulled out. That is, the measuring instrument body 2 does not need to be separated from the outer casing 1. When the measuring instrument body 2 needs to be used, the sliding cover 31 can be pulled directly to the limit length of the telescopic rod 41, and then the outer casing 1 can be put back in place. Figure 2 When the instrument is laid flat as shown, the user can use the measuring instrument body 2 normally. At this time, the bottom surfaces of the outer box 1 and the sliding cover 31 are in contact with the placement position, which provides support for the measuring instrument body 2. This further simplifies the process of taking out the measuring instrument body 2 and placing it for use, and improves the user's work efficiency.
[0032] Furthermore, when the measuring instrument body 2 needs to be inspected and maintained, the user can remove the first fixing bolt 311 and the second fixing bolt 43 respectively, and then remove the measuring instrument body 2 from the sliding cover 31.
[0033] The working principle of this device is as follows:
[0034] When the user needs to take out and use the measuring instrument body 2, firstly, the user opens the buckles 33 on both sides of the outer box 1 and pulls the sliding cover 31 away from the outer box 1. During this process, the slider 32 slides in the sliding groove 11 and the telescopic rod 41 extends in the mounting groove 12. After the telescopic rod 41 reaches its limit length, the measuring instrument body 2 is completely exposed in the outer box 1. At this time, the user can lay the outer box 1 flat and use the measuring instrument body 2 normally.
[0035] When the user needs to repair the measuring instrument body 2, the user can remove the second fixing bolt 43 and the first fixing bolt 311 respectively, first release the restriction of the mounting groove 12 on the telescopic rod 41, and then release the restriction of the sliding cover 31 on the measuring instrument body 2, so that the measuring instrument body 2 can be separated for repair.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
