Description

Technical Field

[0001] The utility model relates to the technical field of detector sealing protection, in particular to a sealing device for a detector. Background Art

[0002] In the field of detector technology, the design of sealing devices is crucial, as it is directly related to the performance stability, service life, and safety of the detector. Traditional detector sealing devices often use bolt fastening, snap-on connections, or adhesive fixation. These methods have many shortcomings in terms of sealing effect, installation convenience, and maintenance costs. For example, while bolt fastening provides good sealing effect, the installation process is cumbersome and requires specialized tools, making it difficult to quickly disassemble and assemble. Snap-on connections may become loose due to long-term use or vibration, affecting sealing performance. Finally, adhesive fixation has problems such as long curing time and aging.

[0003] Furthermore, when performing detection, the detector often requires frequent opening and closing of the sealing device to expose the detection port. This not only increases operational complexity but can also degrade the sealing performance due to repeated disassembly and assembly, and even damage the detector's internal structure. Therefore, it is particularly important to design a sealing device that can quickly and stably seal the detector while facilitating detection operations, while also exhibiting good sealing and structural integrity. To address these technical issues, a sealing device for a detector is proposed. Utility Model Content

[0004] The purpose of the present utility model is to provide a sealing device for a detector, which can quickly and conveniently install and disassemble the sealing protection structure of the detector, and does not require repeated disassembly and installation work when performing detection work. Partial areas can be covered and opened at will when performing detection work, thereby improving the sealing performance of the device.

[0012] The technical solution of the utility model has at least the following beneficial effects:

[0013] 1. The sealing device for the detector aligns the opening with the through hole so that the ring tube is inserted into the protective tube. When the ring tube contacts the inclined surface of the extrusion rod, the rod is driven to move out to both sides according to the action of the force, and the first spring is stretched at the same time. When the ring tube continues to slide upward until the positioning hole moves to the rod insertion position, the rod is driven to be stuck in the positioning hole under the action of the first spring, thereby completing the positioning of the ring tube. The rod can be pulled out of the positioning hole by pulling the connecting plates on both sides, so that the ring tube is easily and automatically ejected, which is more convenient.

[0014] 2. The sealing device for the detector can make the connecting block drive the slide plate to slide in the slide groove when the detector is performing detection work, so as to expose the opening. At the same time, when the connecting block performs arc motion, it will drive the arc rod to slide adaptively in the arc tube, thereby driving the second spring to be compressed in the arc tube, and then the detector can detect the target position through the through hole. In this way, on the one hand, there is no need to repeatedly disassemble and install work during the detection work, and on the other hand, the through hole can be covered and opened at will during the detection work, thereby improving the sealing performance of this device.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] See also Figure 1-4 The utility model proposes a sealing device for a detector, which includes a protective tube 1, a base 2 and a detector body 18, and the detector body 18 is fixedly installed on the upper side of the base 2, the upper side of the protective tube 1 is fixedly connected with a ring tube 3, and the detector body 18 is located inside the ring tube 3, and positioning holes 4 are opened on both sides of the ring tube 3. The two sides of the protective tube 1 are slidably connected with an insertion rod 5, the outside of the insertion rod 5 is fixedly connected with a connecting plate 6, and a first spring 7 is fixedly connected between the connecting plate 6 and the protective tube 1. A pop-up mechanism is provided at the bottom of the inner side of the protective tube 1.

[0027] The insertion rod 5 matches the positioning hole 4. The end of the insertion rod 5 is beveled with the bevel facing downward. The bevel treatment makes it easy to automatically squeeze the insertion rod to both sides by extrusion without manual operation. The first spring 7 is located on both sides of the insertion rod 5. Installing the first spring 7 on both sides of the insertion rod 5 can ensure structural stability.

[0028] The pop-up mechanism includes an elastic telescopic rod 8 and a butt plate 9 . The elastic telescopic rod 8 is fixedly connected to the protective tube 1 . The butt plate 9 is fixedly connected to the elastic telescopic rod 8 , and the butt plate 9 abuts against the upper surface of the annular tube 3 .

[0029] The working principle of a sealing device for a detector based on the first embodiment is that when sealing the detector, the opening 17 can be aligned with the through hole 10, and the ring tube 3 is inserted into the protective tube 1. When the upper surface of the ring tube 3 contacts the inclined surface of the extrusion rod 5, the rod 5 will be driven to move out to both sides according to the action of the force, and the first spring 7 will be stretched at the same time. When the ring tube 3 continues to slide upward, the end of the rod 5 will abut against the outside of the ring tube 3 and slide until the positioning hole 4 moves to the position of the rod 5. Under the action of the first spring 7, the rod 5 will be driven to be stuck in the positioning hole 4, and the sealing is completed. The ring tube 3 is positioned so as to complete the sealing protection of the detector, and when the ring tube 3 is inserted into the protective tube 1, it will drive the counter plate 9 to compress the elastic telescopic rod 8, so that it applies a certain extrusion force to the insertion rod 5, thereby ensuring the stability of the installation. When the detector needs to be disassembled, it is only necessary to pull the connecting plates 6 on both sides to pull the insertion rod 5 out of the positioning hole 4. Due to the gravity factor and the elastic force provided by the elastic telescopic rod 8, the ring tube 3 will be automatically popped out more easily, and the sealing protection and disassembly of the detector can be completed more quickly and conveniently.

[0030] Example 2

[0031] See also Figure 1-8 Based on the first embodiment, a through hole 10 is provided on the outside of the protective tube 1, an opening 17 is provided on the outside of the ring tube 3, and the position of the opening 17 matches the position of the through hole 10. A slide groove 11 is provided on the upper side of the protective tube 1, and the slide groove 11 passes through the through hole 10. A slide plate 12 is slidably connected to the inside of the slide groove 11, and a connecting block 13 is fixedly connected to the upper side of the slide plate 12, and the connecting block 13 protrudes from the upper surface of the protective tube 1, and a reset mechanism is installed on one side of the connecting block 13.

[0032] The reset mechanism includes an arc tube 14, an arc rod 15 and a second spring 16. The arc tube 14 is fixedly connected to the upper side of the protective tube 1, the arc rod 15 is slidably connected to the inside of the arc tube 14, and the second spring 16 is fixedly connected between the arc rod 15 and the arc tube 14.

[0033] The arc-shaped cylinder 14 , the arc-shaped rod 15 and the arc-shaped tracks of the slide groove 11 are overlapped, thus avoiding motion interference so that the slide plate 12 cannot slide in the slide groove 11 .

[0034] In this embodiment, when the detector is detecting, the connecting block 13 can drive the slide plate 12 to slide in the slide groove 11, so that the opening 17 is exposed. At the same time, when the connecting block 13 performs an arc motion, it will drive the arc rod 15 to slide adaptively in the arc tube 14, thereby driving the second spring 16 to be compressed in the arc tube 14, and then the detector can detect the target position through the through hole 10. After the detection work is completed, the connecting block 13 can be loosened. At this time, under the action of the second spring 16, the slide plate 12 will be driven to reset and re-cover the through hole 10. In this way, on the one hand, there is no need to repeatedly disassemble and install work during the detection work, and on the other hand, the through hole 10 can be covered and opened arbitrarily during the detection work, which improves the sealing of the device and is conducive to protecting the structural integrity of the detector.
