A personal dosimeter capable of stable clamping

Abstract

This invention discloses a stable personal dosimeter clamping system, belonging to the field of personal dosimeters. Addressing the problem of unstable clamping in existing technologies, this invention employs a dual-torsion spring driven rotating clamping plate system. A rigid connection between the rotating shaft and the fixed base, combined with symmetrically arranged torsion springs, forms bidirectional elastic support, adaptable to the clamping needs of clothing of varying thicknesses. A reinforcing plate at the end of the rotating clamping plate forms a dual friction interface with a rubber pad. The wavy rubber pad is made of soft silicone material, increasing the contact friction coefficient while preventing damage to the fabric surface. The mechanical interlocking structure between the central reinforcing plate and the insertion block achieves a multi-point positioning clamping mechanism, effectively suppressing lateral displacement. The optimized ratio of the pad and cavity in the rotating clamping plate reduces material usage while maintaining clamping rigidity. This system is particularly suitable for the vigorous movement scenarios encountered by nuclear industry personnel, ensuring reliable fixation of the dosimeter under complex operating conditions.

[0022] 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.

[0023] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0024] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0025] In the embodiments, by Figure 1-5 This utility model provides a structural example, combined with Figure 2 Figure 4 It can be seen that the rotating shaft 3 passes through the through hole 5, allowing the rotating clamp 1 to rotate around the rotating shaft 3, and the torsion spring 4 is sleeved on the rotating shaft 3 to provide thrust to the rotating clamp 1; combined with Figure 2 Figure 3 It can be seen that the bottom surface of the end reinforcement plate 11 is also provided with the first rubber pad 9, the middle reinforcement plate 7 is provided on the middle side of the rotating clamp 1, and the end reinforcement plate 11 is provided on the bottom side of the rotating clamp 1.

[0026] A personal dosimeter capable of stable clamping includes: a measuring instrument 12, with two parallel mounting bases 2 on the side of the measuring instrument 12, and a rotating shaft 3 between the mounting bases 2. A rotating clamping plate 1 and a torsion spring 4 are sleeved on the rotating shaft 3. The torsion spring 4 provides elastic force to the rotating clamping plate 1, and end reinforcement plates 11 are provided on both ends of the rotating clamping plate 1. The end reinforcement plates 11 increase the contact area between the rotating clamping plate 1 and the clothing during clamping, and the additional clamping from both sides makes the clamping more stable.

[0027] As a preferred embodiment of this utility model, a first rubber pad 9 is provided on the bottom surface of each end reinforcing plate 11. The first rubber pad 9 is provided on the bottom surface of the end reinforcing plate 11. The surface of the first rubber pad 9 is wavy. The softer material and the wavy shape can increase the friction when the first rubber pad 9 comes into contact with clothing.

[0028] In a preferred embodiment of this invention, a second rubber pad 13 is provided on the side of the measuring instrument 12, and a pad 6 is provided on the bottom surface of the end of the rotating clamping plate 1, with the second rubber pad 13 located below the pad 6. The addition of the pad 6 at the end prevents the end of the rotating clamping plate 1 from being hollow, allowing more force to be applied to the clothing during contact, resulting in greater friction between the clothing and the pad 6 and the second rubber pad 13. The pad 6 is only provided at the end of the rotating clamping plate 1, avoiding overall filling and significantly reducing production material consumption. Simultaneously, since a first rubber pad 9 is provided on the bottom surface of the end reinforcing plate 11, the clothing clamped at the bottom of the end reinforcing plate 11 and the bottom of the pad 6 is not on the same horizontal line during clamping. A small gap is provided between the second rubber pad 13 on the side of the measuring instrument 12 and the first rubber pad 9 on the bottom surface of the end reinforcing plate 11, allowing the clothing to pass through and be clamped by both the second rubber pad 13 on the side of the measuring instrument 12 and the first rubber pad 9 on the bottom surface of the end reinforcing plate 11, thus forming a double clamping effect and increasing the friction during clamping.

[0029] In a preferred embodiment of this invention, a central reinforcing plate 7 is provided on both sides of the central part of the rotating clamping plate 1. Each central reinforcing plate 7 has a insertion hole 8 on its bottom surface. A insertion block 10 is provided below each insertion hole 8 and is located on the side of the measuring instrument 12. The insertion block 10 can be inserted into the insertion hole 8. The combination of the insertion hole 8 and the insertion block 10 achieves multi-point clamping of the entire invention, making the clamping of clothing more stable when held between the insertion hole 8 and the insertion block 10.

[0030] In a preferred embodiment of this invention, two torsion springs 4 are provided, each capable of providing elastic force to the rotating clamping plate 1. Providing two torsion springs 4 allows for greater elastic force to the rotating clamping plate 1, ensuring sufficient force during clamping.

[0031] Operating principle: When using this utility model, press down the head of the rotating clamp 1, and the tail of the rotating clamp 1 will lift up. At this time, clamp it on the pocket, and the clothes can be clamped between the rotating clamp 1 and the measuring instrument 12. Due to the combination of the pad 6, the first rubber pad 9, and the second rubber pad 13, the friction during clamping is increased. The end reinforcement plate 11 and the middle reinforcement plate 7 realize multi-point clamping and increase the stability during clamping.

[0032] In summary, this utility model employs a rotating clamping plate system driven by dual torsion springs. The rigid connection between the rotating shaft and the fixed base, combined with symmetrically arranged torsion springs, forms bidirectional elastic support, adaptable to the clamping needs of clothing of varying thicknesses. The reinforcing plate added to the end of the rotating clamping plate, along with the second rubber pad and the first and second rubber pads, create a clamping mechanism, forming a dual friction interface. The wavy rubber pad is made of soft silicone material, increasing the contact friction coefficient while preventing damage to the fabric surface. The mechanical interlocking structure between the central reinforcing plate and the insertion block achieves a multi-point positioning clamping mechanism, effectively suppressing lateral displacement. The optimized ratio of the pads to the cavity in the rotating clamping plate ensures clamping rigidity while reducing material usage. This system is particularly suitable for the vigorous movement scenarios encountered by nuclear industry personnel, ensuring the dosimeter remains reliably fixed under complex operating conditions.
