Description

Technical Field

[0001] This utility model belongs to the technical field of static electricity eliminators, specifically relating to a laboratory static electricity eliminator. Background Technology

[0002] The degree of electrostatic damage to instrument components in the training room varies depending on their type; even a static voltage as low as 100V can cause damage or affect instrument readings. In recent years, with the increasing integration of instrument components, the required static voltage has been continuously reduced. However, the static voltage induced by the human body is usually above 2-4KV, typically caused by slight movements or friction with insulating materials. This means that if the static potential we carry in daily life is transferred to the instruments in the training room, almost all instruments will be affected, thus necessitating the development of a laboratory static electricity eliminator.

[0003] Currently, Chinese patent CN220539408U discloses a workshop antistatic guardrail, including a guardrail body with multiple posts. Contact balls are fixedly installed at the top of each post, and nozzles are fixedly installed on both sides of the contact balls on the upper part of the guardrail body. A fan is fixedly installed at the bottom of the guardrail body. Water supply pipes are installed inside the posts, and a control box is fixedly installed on one side of one of the posts. The control box controls the water supply pipes and the fan to spray water and blow air onto the contact balls through the nozzles. In use, the contact balls and grounding wire discharge static electricity from the personnel's bodies, thus achieving static electricity removal. However, when not in use, this technical solution is inconvenient to store because the entire structure cannot be retracted, and it occupies a large amount of space. Utility Model Content

[0005] The technical solution of this utility model is as follows:

[0006] A laboratory static eliminator includes a pressable and retractable elastic telescopic rod and a contact sleeve fixed to the elastic telescopic rod. The contact sleeve is electrically connected to a connecting ball located inside the elastic telescopic rod. The connecting ball is conductive and connected to a wire. The wire is wound around a winding assembly fixed to the elastic telescopic rod, and the other end of the wire is connected to a grounding plate.

[0008] Furthermore, the contact sleeve is connected to a conductive rod that is connected to the connecting ball.

[0009] Furthermore, the first lifting cylinder and the second lifting cylinder, as well as the second lifting cylinder and the third lifting cylinder, are locked and unlocked by pressing the male and female buckles.

[0010] Furthermore, the winding assembly includes two fixed plates fixed inside the third lifting cylinder, two rotating cylinders coaxially fixed on the fixed plates, a conductive post rotatably connected to the two rotating cylinders, and a truncated cone fixed on the fixed plates.

[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 Figure 1-3 As shown, a laboratory static eliminator includes a pressable and retractable elastic telescopic rod and a contact sleeve 1 fixed on the elastic telescopic rod. The contact sleeve 1 is electrically connected to a connecting ball 2 located inside the elastic telescopic rod. The connecting ball 2 is made of conductive material and is fixedly connected to a wire 14. The wire 14 is wound up to a winding assembly 3 fixed on the elastic telescopic rod, and the other end of the wire 14 is fixedly connected to a ground plate 6. The ground plate 6 is fixed on a base 8, and the base 8 is fixed to the bottom of the elastic telescopic rod.

[0022] When in use, the person touches the contact sleeve 1, the contact sleeve 1 receives the static electricity from the human body and then passes through the connecting ball 2, the wire 14, the winding assembly 3 and the grounding plate 6 to contact the ground, thereby realizing the discharge of static electricity;

[0023] When not in use, press the elastic telescopic rod to retract and lock it, thereby reducing the overall size. During the retraction process, as the gap between the connecting ball 2 and the grounding plate 6 decreases, the winding assembly 3 can retract the wire 14, thereby preventing the wire 14 from bending or tangling.

[0024] In this embodiment, the elastic telescopic rod includes a first lifting cylinder 9 fixed to the base 8 at its bottom, a second lifting cylinder 11 inserted into the first lifting cylinder 9, and a third lifting cylinder 12 inserted into the second lifting cylinder 11. The third lifting cylinder 12 is connected to the contact sleeve 1, and the connecting ball 2 is located inside the third lifting cylinder 12. The first lifting cylinder 9 and the second lifting cylinder 11, as well as the second lifting cylinder 11 and the third lifting cylinder 12, are elastically connected by springs 10 and can be pressed and locked. The winding assembly 3 is located inside the third lifting cylinder 12. The sliding distance between the first lifting cylinder 9 and the second lifting cylinder 11, as well as the second lifting cylinder 11 and the third lifting cylinder 12, is limited by sliding grooves and balls to prevent the second lifting cylinder 11 and the third lifting cylinder 12 from detaching from the first lifting cylinder 9 and the second lifting cylinder 11.

[0025] During use, the telescopic adjustment is achieved through the first lifting cylinder 9, the second lifting cylinder 11, and the third lifting cylinder 12 to ensure both use and storage.

[0026] In this embodiment, the contact sleeve 1 is connected to a conductive rod 13 that is connected to the connecting ball 2.

[0027] In this embodiment, the first lifting cylinder 9 and the second lifting cylinder 11, as well as the second lifting cylinder 11 and the third lifting cylinder 12, are locked and unlocked by pressing the male buckle 4 and the female buckle 5.

[0028] When in use, the button 4 and the nut 5 are pressed to lock and unlock, making it easy to store and use.

[0029] In this embodiment, the winding assembly 3 includes two fixed plates 33 fixed inside the third lifting cylinder 12, two rotating cylinders 31 coaxially fixed on the fixed plates 33, a conductive post 37 rotatably connected to the two rotating cylinders 31 via bearings, and a frustum 32 fixed on the fixed plates 33. The conductor 14 is divided into upper and lower sections. The frustum 32 is fixed with a torsion spring 36 fixed to the conductive post 37. The circular side of the conductive post 37 is provided with an annular groove 34. The annular groove 34 is in contact with a conductive spring 38 electrically connected to the upper section of the conductor 14. The conductive spring 38 is fixed on the frustum 32. The upper section of the conductor 14 is connected to the connecting ball 2, and the lower section of the conductor 14 is electrically connected to the conductive post 37 and the grounding plate 6.

[0030] When the elastic telescopic rod is pressed to unlock, the ground plate 6 moves down. At this time, the lower section of the wire 14 drives the conductive post 37 to rotate, and the torsion spring 36 retracts. At this time, the connecting ball 2 achieves electrical conductivity with the lower section of the wire 14 through the upper section of the wire 14, the conductive spring 38, and the conductive post 37. When it is necessary to press to lock, under the action of the torsion spring 36, the conductive post 37 rotates to reset and retracts the lower section of the wire 14, ensuring the storage of the wire 14.

[0031] All of the above electrical connections are made using wires or conductive materials.

[0032] In this embodiment, a plurality of support blocks 7 are fixed to the bottom of the base 8.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
