Description

Technical Field

[0001] This invention relates to the field of packaging tube technology, and more specifically, to an antistatic packaging tube for electronic components. Background Technology

[0002] To ensure that electronic components are not damaged during transportation, they are usually packaged or placed in separate boxes. However, this is quite complicated. Therefore, the staff found that using packaging tubes for transportation is more convenient.

[0003] Existing packaging tubes typically place electronic components at one open end of the tube, allowing them to slide down to the bottom. To avoid damaging the components, this sliding process must be slow, impacting efficiency. When the packaging tube is subjected to external force, this force is directly transmitted to the electronic components, and collisions between the components and the tube can easily lead to component failure. Furthermore, static electricity is easily generated during packaging or transportation due to friction. This static electricity readily attracts small particles, such as hair and dust, causing damage to the electronic components. Therefore, we propose an anti-static packaging tube for electronic components to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-static packaging tube for electronic components, which solves the problems that electronic components are prone to failure due to collisions with the packaging tube, and that static electricity is easily generated due to friction during packaging or transportation. On the one hand, static electricity can easily attract small substances, causing damage to electronic components.

[0005] To achieve the above-mentioned objective, the present invention provides an antistatic packaging tube for electronic components, comprising a packaging tube body and two caps connected around the packaging tube body; wherein rotating the caps enables them to move relative to the packaging tube body in the axial direction.

[0006] The cover includes a supporting body and an extension surrounding the periphery of the supporting body. The extension and the supporting body together form a connecting groove. A groove is provided in the middle of the supporting body. An annular sealing gasket is provided on the inner wall of the groove. The annular sealing gasket is suitable for pressing against the inner wall of the top opening of the packaging tube when the top opening of the packaging tube is in a closed state by the supporting body. Furthermore, the supporting body is provided with a tightening structure for fastening the annular sealing gasket to the top wall of the groove.

[0007] Using the above solution, the cover can be threadedly connected to the packaging tube to form a fixed structure, effectively preventing electronic components from falling out. At the same time, when the cover is threadedly connected, the tightening structure can push the annular sealing gasket to deform, so that the annular sealing gasket can further seal the packaging tube, effectively improving the dustproof and moisture-proof function of the packaging tube.

[0008] The inside of the cover is also equipped with a load unit for absorbing static electricity. The load unit is used to absorb the charge inside and outside the packaging tube, forming static electricity transfer, which effectively ensures the safety of electronic components.

[0009] The packaging tube includes a hollow tube for carrying electronic components. The inner wall of the hollow tube is fixedly connected to a ring of guide rods, and a support assembly is inserted into the outer wall of the guide rods. The side wall of the hollow tube is provided with a static-absorbing part for absorbing static electricity. With the above solution, the support assembly can effectively support the electronic components, making it easy to insert them into the packaging tube. On the other hand, it can form elastic deformation to resist inertia when shaking occurs, thus solving the problem that electronic components are easily damaged by collision with the tube wall.

[0010] As a preferred technical solution of the present invention, the electrostatic absorption part includes an electrostatic conductor disposed on the side wall of the hollow tube, a metal fiber mesh disposed on the inner wall of the hollow tube, and a current-collecting ring disposed on the top of the inner side wall of the hollow tube, wherein the hollow tube is made of insulating material.

[0011] As a preferred technical solution of the present invention, the support assembly includes a support frame, and the inner side wall of the support frame is provided with a tightening member. The tightening member is in the shape of a hollow inverted frustum and is made of rubber. The side wall of the tightening member is provided with a triangular expansion groove. The side wall of the support frame is also provided with four first guide grooves, which are adapted to guide rods.

[0012] As a preferred technical solution of the present invention, the support component includes two semi-circular slides, one end of which is fixedly connected to a locking block, and the other end of which is provided with a locking groove. The locking block is adapted to the locking groove. A buffer plate is provided on the inner sidewall of the semi-circular slide. The buffer plate is made of rubber, and a trapezoidal expansion groove is provided on the surface of the buffer plate. A second guide groove is provided on the sidewall of the semi-circular slide.

[0013] As a preferred technical solution of the present invention, the inner wall of the hollow tube is provided with a first thread, the side wall of the supporting body is provided with a first thread that matches the first thread, the inner wall of the extension is provided with a second thread, and the top of the outer wall of the hollow tube is provided with a second thread that matches the second thread.

[0014] As a preferred technical solution of the present invention, the clamping structure includes a slide that is slidably connected to the side wall of the support body. A disc is fixedly connected to the top of the slide, and a guide portion is provided at the bottom of the slide. The guide portion is used to drive the disc to move relative to the support body in the axial direction before and after the guide portion contacts the flow-gathering ring.

[0015] As a preferred technical solution of the present invention, a metal conductor is fixedly connected to the inner side wall of the carriage, and a metal receiving part adapted to the metal conductor is fixedly connected to the edge of the support body. The metal receiving part is a copper piece with an inclined sliding surface adapted to the metal conductor at the bottom.

[0016] As a preferred technical solution of the present invention, the metal receiving part is an elastic metal sheet, the metal sheet includes a sheet-like conductor, the bottom of the sheet-like conductor is bent inward to form an elastic deformation part, and the elastic deformation part can move closer to the sheet-like conductor when subjected to compressive force.

[0017] As a preferred technical solution of the present invention, the support body has a cavity inside, and the load unit includes a charge conversion unit, a resistance unit and a grounding unit fixedly connected to the inner wall of the cavity. The charge conversion unit, the resistance unit and the grounding unit are electrically connected to the metal receiving part through a wire conductor.

[0018] As a preferred technical solution of the present invention, a buffer seat is fixedly connected to the bottom of the support body, and a placement groove is provided in the middle of the buffer seat. The buffer seat is made of rubber.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] In the solution of this invention:

[0021] 1. By setting up the packaging tube body, cover body, tightening structure and annular sealing gasket, the cover body can be threadedly connected to the packaging tube body to form a fixed structure, effectively preventing electronic components from falling out. At the same time, when the cover body is threadedly connected, the tightening structure can push the annular sealing gasket to deform, so that the annular sealing gasket can further seal the packaging tube body, effectively improving the dustproof and moisture-proof function of the packaging tube.

[0022] 2. By using hollow tubing, guide rods, and support components, electronic components are inserted into the support frame and fixed by the tightening components inside the support frame. On the one hand, during installation, the friction between the support frame and the inner wall of the packaging tube prevents the electronic components from directly rubbing against the packaging tube. On the other hand, the tightening components support the electronic components through their own elasticity, and form elastic deformation to resist inertia when shaking occurs, thus solving the problem that electronic components are easily damaged by colliding with the tube wall.

[0023] 3. By incorporating a current-collecting ring, metal fiber mesh, electrostatic conductor, metal conductor, charge conversion unit, resistor unit, and grounding unit, the threaded connection between the cover and the packaging tube allows the metal conductor to form an electrical connection with the current-collecting ring. Simultaneously, when the cover is separated from the packaging tube, an electrical disconnection occurs. When the electrical connection is established, the charge inside and outside the packaging tube can be transferred to the resistor unit and then further to the grounding unit, thereby absorbing the charge inside and outside the packaging tube and forming electrostatic transfer, effectively ensuring the safety of electronic components.

[0043] Please see Figures 1 to 10 The present invention provides a technical solution: an antistatic packaging tube for electronic components.

[0044] Example 1:

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, this embodiment proposes an antistatic packaging tube for electronic components, including a packaging tube body 10 and two caps 20 connected around the packaging tube body 10; wherein rotating the caps 20 enables them to move in the axial direction relative to the packaging tube body 10.

[0046] The cover 20 includes a support body 201 and an extension 202 surrounding the support body 201. The extension 202 and the support body 201 together form a connecting groove 203. A groove 2011 is provided in the middle of the support body 201. An annular sealing gasket 21 is provided on the inner wall of the groove 2011. The annular sealing gasket 21 is suitable for pressing against the inner wall of the top opening 15 of the packaging tube 10 when the top opening 15 is closed by the support body 201. The support body 201 is provided with a tightening structure 22 for fastening the annular sealing gasket 21 to the top wall of the groove 2011.

[0047] Using the above solution, the cover 20 can be threadedly connected to the packaging tube 10 to form a fixed structure, effectively preventing electronic components from falling out. At the same time, when the cover 20 is threadedly connected, the tightening structure 22 can push the annular sealing gasket 21 to deform, so that the annular sealing gasket 21 further seals the packaging tube 10, effectively improving the dustproof and moisture-proof function of the packaging tube.

[0048] The inside of the cover 20 is also provided with a load unit 30 for absorbing static electricity. The load unit 30 is used to absorb the charge inside and outside the packaging tube, forming static electricity transfer, which effectively ensures the safety of electronic components.

[0049] The packaging tube 10 includes a hollow tube 11 for carrying electronic components. A guide rod 12 arranged in a ring is fixedly connected to the inner side wall of the hollow tube 11. A support assembly 13 is inserted into the outer wall of the guide rod 12. The side wall of the hollow tube 11 is provided with an electric shock absorbing part 14 for absorbing static electricity. With the above solution, the support assembly 13 can effectively support the electronic components. On the one hand, it is convenient to insert them into the packaging tube 10. On the other hand, it forms elastic deformation to resist inertia when shaking occurs, which solves the problem that electronic components are easily damaged by collision with the tube wall.

[0050] like Figure 1 , Figure 2 and Figure 6 As shown, the electrostatic absorption section 14 includes an electrostatic conductor 141 disposed on the side wall of the hollow tube 11, a metal fiber mesh 142 disposed on the inner wall of the hollow tube 11, and a current-gathering ring 143 disposed on the top of the inner side wall of the hollow tube 11. The hollow tube 11 is made of insulating material. In order to ensure the effect of absorbing static electricity, several electrostatic conductors 141 are disposed. The electrostatic conductors 141 are distributed in a ring in the hollow tube 11. At the same time, the inner wall of the hollow tube 11 is also provided with a staggered metal fiber mesh 142. The metal fiber mesh 142 and the electrostatic conductors 141 form a parallel circuit to absorb static electricity and gather the absorbed static electricity in the current-gathering ring 143. When the current-gathering ring 143 is connected to the load unit 30, the charge can be transferred to the load unit 30 through the potential difference to realize the static electricity transfer, thereby removing the static electricity inside and outside the packaging tube 10.

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 9 and Figure 10As shown, the support assembly 13 includes a support frame 131. A tightening member 132 is provided on the inner wall of the support frame 131. The tightening member 132 is a hollow, inverted frustum shape and is made of rubber. A triangular expansion groove 133 is provided on the side wall of the tightening member 132. Four first guide grooves 134 are also provided on the side wall of the support frame 131. The first guide grooves 134 are adapted to the guide rods 12. During use, the operator can insert electronic components into the support frame 131, which then slides onto the guide rods 12 and into the packaging tube 10. The advantage of this design is that the movement during installation is achieved through the support frame 131, rather than by the electronic components themselves. The components can be moved directly, which directly solves the problem of electronic components being easily damaged by friction with the inner wall of the packaging tube 10 during installation. Furthermore, the support frame 131 can also protect the electronic components because the inner wall of the support frame 131 has a tightening member 132. When the electronic components are inserted into the tightening member 132, they will first expand the tightening member 132, causing the tightening member 132 to expand. Therefore, the tightening member 132 has the potential energy to return to the center. Under this potential energy, the tightening member 132 can directly resist the inertial potential energy of the electronic components during transportation, thus achieving effective protection of the electronic components and preventing damage caused by shaking.

[0052] The inner wall of the hollow tube 11 is provided with a first thread 111, the side wall of the support body 201 is provided with a first thread 2013 that is adapted to the first thread 111, the inner wall of the extension 202 is provided with a second thread 2021, and the top of the outer wall of the hollow tube 11 is provided with a second thread 112 that is adapted to the second thread 2021. The first thread 111 and the first thread 2013 are adapted to each other, and the second thread 112 and the second thread 2021 are adapted to each other. Therefore, when the first thread 111 and the first thread 2013 are engaged, they can simultaneously drive the second thread 112 and the second thread 2021 to engage with each other, thereby achieving double fixation and effectively improving the stability between the packaging tube 10 and the cap 20.

[0053] The clamping structure 22 includes a slide 221 slidably connected to the side wall of the support body 201. In this embodiment, the inner wall of the support body 201 is also provided with a balance groove adapted to the slide 221. The slide 221 can move up and down in the balance groove. A disc 223 is fixedly connected to the top of the slide 221. The disc 223 is adapted to the annular sealing gasket 21 and is used to press against the annular sealing gasket 21 to deform it, so that the annular sealing gasket 21 further forms a sealing structure. A guide part 222 is provided at the bottom of the slide 221. The guide part 222 is used to drive the disc 223 relative to the support body 201 along the front and back when the guide part 222 contacts the flow-collecting ring 143. The axial movement means that the guide part 222 can drive the drive disc 223 to slide up and down relative to the support body 201. The prerequisite for sliding up and down is contact with the flow-collecting ring 143. Before contacting the flow-collecting ring 143, due to gravity, the disc 223 and the slide 221 slide to the lowest point, that is, the bottom of the inner bottom wall of the disc 223 contacts the bottom of the groove 2011. When the cover 20 is threadedly connected to the packaging tube 10, the slide 221 contacts the flow-collecting ring 143. Under the tight state of the flow-collecting ring 143, the slide 221 moves upward, thereby pushing the disc 223 upward to press against the annular sealing gasket 21, causing the annular sealing gasket 21 to deform, thereby achieving a sealing structure.

[0054] A metal conductor 224 is fixedly connected to the inner wall of the slide 221. A metal receiving part 225 adapted to the metal conductor 224 is fixedly connected to the edge of the support body 201. The metal receiving part 225 is a copper part with an inclined sliding surface at the bottom adapted to the metal conductor 224. The metal conductor 224 is set through the slide 221, so that the metal conductor 224 can achieve electrical connection. In order to ensure that the metal conductor 224 can smoothly conduct away the charge on the current collecting ring 143, the adhesive used to bond the metal conductor 224 and the slide 221 can be set as a conductive adhesive. When the slide 221 is lifted, it can not only achieve the effect of promoting sealing, but also achieve the purpose of electrical connection. That is to say, when the slide 221 slides to the top, it can drive the metal conductor 224 to connect with the metal receiving part 225. Since they are both conductive metals, they can achieve electrical connection, and the collected charge is transferred to the load unit 30 through the metal conductor 224 and the metal receiving part 225, realizing electrostatic transfer.

[0055] The support body 201 has an internal cavity 2012. The load unit 30 includes a charge conversion unit 31, a resistor unit 32, and a grounding unit 33, which are fixedly connected to the inner wall of the cavity 2012. The charge conversion unit 31, resistor unit 32, and grounding unit 33 are electrically connected to the metal receiving part 225 via conductors. The charge conversion unit 31 converts the collected static electricity into a small current and transmits it to the resistor unit 32 and grounding unit 33, where the transfer and consumption of charge are completed. In practical applications, the grounding unit 33 can be connected to the outside of the cover 20 via a conductor to facilitate the release of static electricity generated during storage and movement, preventing static electricity accumulation from damaging electronic devices.

[0056] A buffer seat 204 is fixedly connected to the bottom of the support body 201. A placement groove is provided in the middle of the buffer seat 204. The buffer seat 204 is made of rubber. The two ends of the electronic components are placed in the buffer seat 204. Even if they swing up and down, they can be buffered in the buffer seat 204, effectively avoiding damage to the electronic components.

[0057] Example 2:

[0058] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 9 and Figure 10As shown, in a preferred embodiment, based on the above method, the support component 13 further includes two semi-circular slides 135. One end of each semi-circular slide 135 is fixedly connected to a locking block 136, and the other end of each semi-circular slide 135 has a slot 137. The locking block 136 is adapted to the slot 137. A buffer plate 138 is provided on the inner sidewall of the semi-circular slide 135. The buffer plate 138 is made of rubber, and a trapezoidal expansion groove is provided on its surface. A second guide groove 139 is provided on the sidewall of the semi-circular slide 135. To facilitate the installation of the support component 13, the support component 13 is configured as two parts. The two semi-circular slides 135 are connected by the locking block 136 and the slot 137. The locking block 136 can be a magnetic block, and the inner wall of the slot 137 is configured to be compatible with a magnet and can attract metal or a magnet. Under the premise of effective attraction, it can... The design allows for quick and easy installation. The two interlocking semi-circular slides 135 can be directly assembled, eliminating the need for insertion steps and further improving safety. Simultaneously, the two interlocking semi-circular slides 135 can be synchronously inserted into the guide rod 12, smoothly sliding along the guide rod 12 to guide the electronic components into the packaging tube 10. The support structure formed by the two semi-circular slides 135 also protects the electronic components. Because the inner wall of the semi-circular slide 135 has a buffer disc 138, when the electronic components are inserted into the buffer disc 138, they first push the buffer disc 138 to the periphery, causing it to deform and expand. Therefore, the buffer disc 138 has a potential energy converging towards the center. Under this potential energy, the buffer disc 138 can directly counteract the inertial potential energy of the electronic components during transportation, thus effectively protecting the electronic components and preventing damage caused by shaking. Furthermore, one or more support components 13 can be flexibly selected to fix a single device according to its size, eliminating the need to manufacture special support components for different models of electronic devices. This makes the device highly versatile and easy to produce and use.

[0059] Example 3

[0060] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 10As shown, in a preferred embodiment, based on the above method, further, in order to facilitate the installation of the metal receiving part 225 and ensure normal electrical connection, the metal receiving part 225 can be configured as a flexible component, such as FPC or some soft metal strips or sheets. Specifically, the metal receiving part 225 is an elastic metal sheet, which includes a sheet-like conductor 2251. The bottom of the sheet-like conductor 2251 is bent inward to form an elastic deformation part 2252. The elastic deformation part 2252 can move closer to the sheet-like conductor 2251 when subjected to compressive force. In addition, the elastic deformation part 2252 and the sheet-like conductor 2251 are integrally formed into a hook shape to ensure that the metal receiving part 225 has elastic potential energy to reset when deformed under pressure, thereby ensuring that the metal receiving part 225 can function normally and achieve better electrical connection.

[0061] Specifically, during operation / use, the anti-static packaging tube for electronic components works as follows: The electronic component is inserted into the support frame 131 and supported and fixed by the tightening member 132 within the support frame 131. The tightening member 132 supports the electronic component through its own elasticity, forming elastic deformation to resist inertia when shaking occurs. Then, the support frame 131 with the electronic component is inserted into the packaging tube body 10 via the guide rod 12, preventing the electronic component from directly colliding and rubbing against the inner wall of the packaging tube body 10 during insertion. Furthermore, multiple support frames 131 can be used to support and fix one electronic component during use. The cover 20 is then threadedly connected to the packaging tube body 10 to form a fixed structure, effectively preventing the electronic component from falling out. Simultaneously, when the cover 20 is threadedly connected, the tightening structure 22 pushes the annular sealing gasket 21 to deform, thus preventing the annular sealing gasket from falling out. The sealing gasket 21 further seals the packaging tube 10, effectively improving its dustproof and moisture-proof function. After the threaded connection is fixed, the metal conductor 224 is connected to the metal receiving part 225. Since they are both conductive metals, they can achieve electrical connection. The metal fiber mesh 142 and the electrostatic conductor 141 form a parallel circuit to absorb static electricity and collect the absorbed static electricity in the current-collecting ring 143. After the current-collecting ring 143 is connected to the metal conductor 224 and the metal receiving part 225, an electrical path is formed. The collected charge is transferred to the charge conversion unit 31 through the metal conductor 224 and the metal receiving part 225. The charge conversion unit 31 converts the collected static electricity into a small current and transmits it to the resistor unit 32 and the grounding unit 33. The transfer and consumption of charge are completed in the resistor unit 32 and the grounding unit 33.

Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
