Description

Technical Field

[0001] The present invention relates to the technical field of electrostatic discharge, and more particularly to an electrostatic discharger capable of preventing electrostatic shock. Background Art

[0002] An electrostatic discharger is a safety device used to eliminate static electricity from the human body or objects. When a person has static electricity and touches the electrostatic discharger, the static electricity will be safely discharged to the ground through the conductive path inside it. Its main function is to prevent the risk of electric shock caused by static electricity accumulation and to avoid fire and explosion accidents caused by static electricity sparks in flammable and explosive places. It is widely used in the electronics manufacturing, chemical industry and other industries to ensure the safety of personnel and equipment.

[0003] Currently, the method of directly grounding a metal conductor to discharge is used to eliminate static electricity from the human body. When the user's hand touches the metal conductor, the static electricity is released quickly, resulting in an instantaneous discharge phenomenon, which will give the user a sense of electric shock and may even generate sparks, causing fires and explosions. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an electrostatic discharger capable of preventing electrostatic shock. The technical problem to be solved by the present invention is that when the user's hand touches a metal conductor, the static electricity is released quickly, resulting in an instantaneous discharge phenomenon, which will give the user a sense of electric shock and may even generate sparks, causing fire and explosion accidents.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An electrostatic discharger capable of preventing electrostatic shock comprises a base, a telescopic sleeve fixedly mounted on the top surface of the base, an extension rod slidably connected inside the telescopic sleeve, the telescopic sleeve drives the extension rod to slide through a driving mechanism, a vertical pole fixedly mounted on the top surface of the extension rod, a grounding wire connected to the outer side of the vertical pole, and the grounding wire is grounded, a dustproof box fixedly mounted on the top of the vertical pole, the top of the vertical pole extends to the inside of the dustproof box and is equipped with a discharge plate, a touch pad is elastically connected to the bottom wall of the dustproof box, a limiting pad is installed on the top surface of the touchpad, an arc-shaped conductive plate is installed on the top surface of the discharge plate, and both ends of the arc-shaped conductive plate are slidably connected to the discharge plate, and the top of the arc-shaped conductive plate contacts the bottom surface of the touchpad, a reset mechanism is provided on the arc-shaped conductive plate, and an auxiliary pressing mechanism is provided on the top surface of the dustproof box.

[0007] like Figure 1-6As shown, the implementation method is specifically as follows: by arranging a telescopic sleeve, an extension rod, and a driving mechanism, the extension rod can be made to slide in the telescopic sleeve through the driving mechanism, thereby adjusting the height of the dustproof box for use by people of different heights; by arranging a touch pad, a limit pad, and an arc-shaped conductive plate, the user's hand is placed on the limit pad, and the two ends of the arc-shaped conductive plate are connected to the discharge plate. At this time, the contact area is small and the resistance is relatively large. At this time, the static electricity release speed is relatively slow. As the user presses, the arc-shaped conductive plate is extended and gradually spread on the discharge plate, thereby gradually increasing the contact area. The small contact area and large resistance in the initial stage can avoid the instantaneous release of a large amount of static electricity and produce a strong electric shock. As the contact area increases, the static electricity can be released smoothly and quickly, thereby improving the safety and efficiency of static electricity discharge.

[0008] In a preferred embodiment, the reset mechanism includes two sliders, and the two sliders are respectively installed at both ends of the arc-shaped conductive plate, a slide groove is opened on the top surface of the discharge plate, and each slider is slidably connected in the slide groove, and a reset spring is installed between the two sliders.

[0009] In a preferred embodiment, the auxiliary pressing mechanism includes an electric telescopic rod, and the electric telescopic rod is fixedly mounted on the top wall of the dustproof box, an airbag is fixedly mounted on the bottom end of the electric telescopic rod, and the airbag is located directly above the limiting pad.

[0010] In a preferred embodiment, the driving mechanism comprises a motor, and the motor is fixedly mounted on the bottom wall of the telescopic sleeve, the output shaft of the motor is connected to a threaded rod, and the threaded rod is threadedly connected to the extension rod.

[0011] In a preferred embodiment, a plurality of spring telescopic rods are symmetrically mounted on the bottom wall of the dustproof box, and the top end of each spring telescopic rod is fixedly connected to the bottom surface of the touch panel.

[0012] In a preferred embodiment, a square cavity is defined in the telescopic sleeve, and each outer side of the extension rod is in contact with the inner wall of the square cavity.

[0013] In a preferred embodiment, a rainproof roof is fixedly installed on the top surface of the dustproof box, a visual panel is installed on the outside of the dustproof box, an inlet and outlet hole is opened on the outside of the dustproof box, and an indicator light is installed on the outside of the dustproof box.

[0014] In a preferred embodiment, a dust curtain is installed in the inlet and outlet hole, and the material of the arc-shaped conductive plate is conductive rubber.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides a touch pad, a limit pad, an arc-shaped conductive plate, a discharge plate and other devices, so that the user places his hand on the limit pad and squeezes the limit pad to drive the touch pad to slide downward, so that the arc-shaped conductive plate is gradually spread on the discharge plate, so that the contact area gradually increases and the resistance gradually decreases. The smaller contact area and larger resistance in the initial stage can avoid the strong electric shock caused by the instantaneous release of static electricity. As the contact area increases, the static electricity can be released smoothly and quickly, thereby improving the safety and efficiency of static electricity discharge.

[0017] 2. The present invention realizes the purpose of changing the height of the dustproof box by arranging a telescopic sleeve, an extension rod, a threaded rod, a motor and other devices, and driving the threaded rod to rotate by the motor to make the extension rod slide in the telescopic sleeve, thereby facilitating use by people of different heights.

[0018] In summary, the present invention is easy to operate when in use, and the height of the dustproof box can be changed to facilitate use by people of different heights. At the same time, it avoids the strong electric shock caused by the instantaneous release of large amounts of static electricity and reduces possible sparks, so that static electricity can be released smoothly and quickly, thereby improving the safety and efficiency of static electricity discharge.

DETAILED DESCRIPTION

[0026] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0027] Reference Figure 1-6 , an electrostatic discharger capable of preventing electrostatic shock, comprises a base 1, a telescopic sleeve 2 is fixedly mounted on the top surface of the base 1, an extension rod 3 is slidably connected in the telescopic sleeve 2, the telescopic sleeve 2 drives the extension rod 3 to slide through a driving mechanism, a vertical pole 4 is fixedly mounted on the top surface of the extension rod 3, a grounding wire 5 is connected to the outer side of the vertical pole 4, and the grounding wire 5 is grounded, a dustproof box 6 is fixedly mounted on the top of the vertical pole 4, the top of the vertical pole 4 extends to the inside of the dustproof box 6 and is installed with a discharge plate 15, a touch pad 17 is elastically connected to the bottom wall of the dustproof box 6, a limiting pad 18 is installed on the top surface of the touch pad 17, an arc-shaped conductive plate 20 is installed on the top surface of the discharge plate 15, and both ends of the arc-shaped conductive plate 20 are slidably connected to the discharge plate 15, and the top of the arc-shaped conductive plate 20 is in contact with the bottom surface of the touch pad 17, a reset mechanism is provided on the arc-shaped conductive plate 20, and an auxiliary pressing mechanism is provided on the top surface of the dustproof box 6.

[0028] like Figure 1-6 As shown, the implementation method is specifically as follows: by setting the telescopic sleeve 2, the extension rod 3, and the driving mechanism, the extension rod 3 can be made to slide in the telescopic sleeve 2 through the driving mechanism, thereby adjusting the height of the dustproof box 6, which is convenient for people of different heights to use; by setting the touch pad 17, the limit pad 18, and the arc-shaped conductive plate 20, the user's hand is placed on the limit pad 18, and the arc-shaped conductive plate 20 is connected to the discharge plate 15 through both ends. At this time, the contact area is small and the resistance is relatively large. At this time, the static electricity release speed is relatively slow. As the user presses, the arc-shaped conductive plate 20 is extended and gradually spread on the discharge plate 15, thereby gradually increasing the contact area. The small contact area and large resistance in the initial stage can avoid the instantaneous release of a large amount of static electricity and produce a strong electric shock. As the contact area increases, the static electricity can be released smoothly and quickly, thereby improving the safety and efficiency of static electricity discharge.

[0029] The reset mechanism includes two sliders 21, and the two sliders 21 are respectively installed at the two ends of the arc-shaped conductive plate 20. A slide groove 19 is opened on the top surface of the discharge plate 15, and each slider 21 is slidably connected in the slide groove 19. A reset spring 22 is installed between the two sliders 21. It is worth mentioning that the arc-shaped conductive plate 20 itself is elastic and can automatically restore its initial shape. The action of the slider 21 and the reset spring 22 accelerates the reset of the arc-shaped conductive plate 20, so that the device can quickly prepare for the next electrostatic discharge operation.

[0030] The auxiliary pressing mechanism includes an electric telescopic rod 13 , and the electric telescopic rod 13 is fixedly mounted on the top wall of the dustproof box 6 , an airbag 14 is fixedly mounted on the bottom end of the electric telescopic rod 13 , and the airbag 14 is located directly above the limiting pad 18 .

[0031] It is worth noting that the airbag 14 is filled with gas, and pressure is applied through the electric telescopic rod 13, thereby driving the airbag 14 to squeeze the hand, helping the user to press the touchpad 17, while the airbag 14 avoids causing damage to the hand.

[0032] The driving mechanism includes a motor 12 , and the motor 12 is fixedly mounted on the bottom wall of the telescopic sleeve 2 . The output shaft of the motor 12 is connected to a threaded rod 11 , and the threaded rod 11 is threadedly connected to the extension rod 3 .

[0033] A plurality of spring telescopic rods 16 are symmetrically mounted on the bottom wall of the dustproof box 6, and the top end of each spring telescopic rod 16 is fixedly connected to the bottom surface of the touch panel 17. The touch panel 17 can be reset by the force of the plurality of spring telescopic rods 16, so as to facilitate the next operation.

[0034] A square cavity is provided in the telescopic sleeve 2, and each outer side of the extension rod 3 is in contact with the inner wall of the square cavity. The extension rod 3 is limited by the square cavity so that it cannot rotate and can only move linearly.

[0035] A rain shield 7 is fixedly installed on the top surface of the dustproof box 6, a visual panel 8 is installed on the outside of the dustproof box 6, an inlet and outlet hole 9 is opened on the outside of the dustproof box 6, and an indicator light 10 is installed on the outside of the dustproof box 6. The visual panel 8 makes it convenient for the user to place his hand on the limit pad 18, and the indicator light 10 can be used to remind the user whether the electrostatic discharge is completed.

[0036] A dust curtain is installed in the inlet and outlet hole 9, and the arc-shaped conductive plate 20 is made of conductive rubber. The dustproof box 6 and the dust curtain can reduce the influence of external dust on the internal part, thereby ensuring the conductive performance of the equipment.

[0037] When the present invention is used, the motor 12 can be started to drive the threaded rod 11 to rotate, and then the threaded rod 11 can be threadedly connected with the extension rod 3 to drive the threaded rod 11 to slide, thereby changing the height of the dustproof box 6, so as to adapt to the use of people of different heights;

[0038] Then the user puts his hand into the dustproof box 6 through the inlet and outlet hole 9, observes the interior through the visual panel 8, and places his hand on the limit pad 18, then starts the electric telescopic rod 13 to drive the airbag 14 to slide downward, thereby pressing the hand and driving the touch panel 17 to slide downward, compressing the spring telescopic rod 16 and the arc-shaped conductive plate 20. At this time, the top of the arc-shaped conductive plate 20 contacts the touch panel 17, and at the same time, the two ends of the arc-shaped conductive plate 20 contact the discharge plate 15, the contact area is small, and thus the resistance is large, and the static electricity release speed is relatively slow, so as to avoid the instantaneous large current causing electric shock to the user. The possibility of spark generation is reduced. With the continuous squeezing of the airbag 14, the arc-shaped conductive plate 20 is gradually spread on the surface of the discharge plate 15, and the contact area is gradually increased, so that the static electricity can be released smoothly and quickly. When the static electricity is released, the indicator light 10 will light up to indicate that the static electricity has been released. Then the electric telescopic rod 13 drives the airbag 14 to slide upward, and the user can take his hand out. The touch panel 17 is reset under the action of the spring telescopic rod 16, and the arc-shaped conductive plate 20 is reset under the action of the slider 21 and the reset spring 22, so as to prepare for the next static electricity release.

[0039] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
