Description

Technical Field

[0001] This invention relates to a guardrail component and its connection method, and more particularly to an anti-collision combined guardrail component and its connection method, belonging to the field of building engineering technology. Background Technology

[0002] The main functions of the crash barrier components during construction are reflected in the following aspects:

[0003] Safety protection function

[0004] Preventing vehicles from rushing into the construction site: This is the most basic and important function of crash barriers. When a vehicle goes out of control or collides, the modular barriers can effectively prevent the vehicle from rushing into the construction site, thereby protecting the lives of passengers and preventing damage to the construction site.

[0005] Protecting pedestrian safety: The construction site has a pedestrian walkway to guide pedestrians and ensure their safety.

[0006] Guiding traffic flow: Combination guardrails, through their physical shape and color markings, can guide vehicles to travel in designated lanes, prevent vehicles from deviating from their lanes, and maintain traffic order.

[0007] Improving nighttime driving safety: At night or in inclement weather conditions, reflective markings or lighting on guardrails can alert drivers to the road conditions and prevent traffic accidents caused by poor visibility.

[0008] Existing guardrails are typically simple structures consisting of beams and support posts fixed together. They lack cushioning in the event of a vehicle losing control or colliding with another vehicle, resulting in a direct impact. The guardrails are quite rigid and can stop the vehicle directly, while the driver, due to inertia, may be thrown out, causing a more serious traffic accident. In addition, existing indicator lights are fixed to the construction site using LED strips. Long-term exposure to wind and sun significantly reduces the lifespan of these LED strips, and they lack alarm functions. Therefore, workers need to conduct regular inspections to ensure the stability of the construction guardrails.

[0009] Therefore, it is urgent to improve the anti-collision structure of the guardrail to solve the above-mentioned problems. Summary of the Invention

[0010] The purpose of this invention is to provide a crash-resistant modular guardrail component and its connection method. Multiple protective covers are installed inside the supporting beam, increasing the crash-resistant area without affecting each other. The rubber and foam buffer rings on the buffer ring provide a certain pressure relief function, thus improving both the crash-resistant performance and the service life of the device. Multiple path indicator lights on the multiple protective covers are connected in parallel without affecting each other, improving the flexibility of use. If the supporting beam undergoes severe deformation, the speaker and alarm indicator lights will sound an alarm, facilitating timely maintenance and upkeep of the protective covers by staff, improving the timeliness and safety of the device, ensuring the safety of the construction site, and showing good application prospects.

[0011] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0015] The upper end of the terminal block is provided with symmetrically distributed electrode slots, and a conductive rod is provided inside the electrode slot. The conductive rod is fixed inside the electrode slot by an electrode spring.

[0016] A conductive sheet is fixedly installed inside the wiring support post. The conductive sheet abuts against and is electrically connected to the wiring support post. The conductive sheet is electrically connected to an external power source through a wire.

[0017] An indicator light slot is provided on the outer side of the protective cover, and a path indicator light is fixedly installed inside the indicator light slot. The path indicator light is electrically connected to the conductive rod.

[0018] Preferably, a rubidium magnet connecting block is fixedly disposed between the two electrode slots, and a magnet connecting assembly is disposed between the rubidium magnet connecting block and the supporting crossbeam. The magnet connecting assembly includes a first rubidium magnet and a second rubidium magnet, and the first rubidium magnet is fixedly disposed inside the supporting crossbeam.

[0019] The second rubidium magnet is fixedly disposed on the upper side of the rubidium magnet connecting block, and the first rubidium magnet and the second rubidium magnet are electrically connected.

[0020] Preferably, the upper end of the terminal block is provided with symmetrically distributed guide grooves, and symmetrically distributed guide blocks are fixedly provided on the support beam, with the guide blocks slidably disposed inside the guide grooves.

[0021] Preferably, a terminal spring is provided between the terminal and the terminal support platform, and a terminal limiting block is fixedly provided at the bottom of the terminal.

[0022] Preferably, the protective cover has a C-shaped structure, and both ends of the protective cover are connected to limit blocks, which are slidably disposed inside the buffer groove;

[0023] The protective cover has several evenly distributed nut joints fixedly installed on one side near the supporting beam. The supporting beam has several evenly distributed supporting beam assembly holes. The nut joints are threadedly connected to the protective cover bolts. The protective cover bolts pass through the supporting beam assembly holes, and a bolt guide spring is provided between the protective cover bolts and the supporting beam.

[0024] Preferably, the support column has a column assembly hole corresponding to the support beam assembly hole, and a crossbeam fixing bolt is fixedly installed inside the column assembly hole. The crossbeam fixing bolt passes through the support beam assembly hole and the column assembly hole and fixes the support crossbeam and the protective cover.

[0025] Preferably, a processing chip is fixedly disposed on the upper side of the supporting beam, the conductive sheet is electrically connected to the processing chip, a speaker is fixedly disposed on the upper end of the processing chip, and an alarm indicator light is fixedly disposed on the upper end of the speaker.

[0026] Preferably, the speaker and the alarm indicator light are connected in parallel, and then connected in parallel with the path indicator light; the magnetic connection assembly is connected to a resistor R after being connected in parallel with the speaker and the alarm indicator light.

[0027] A resistor R is connected in series with the path indicator light. G .

[0028] A method for connecting a composite guardrail component includes the following steps:

[0029] Step 1: First, fix the support columns on both sides of the construction site and secure them.

[0030] Step 2: The rubber buffer ring is processed by injection molding, and the foam buffer ring is fixedly installed inside the rubber buffer ring to complete the installation of the buffer ring;

[0031] Step 3: Slide the protective cover into the interior of the support beam through one end, and install the conductive plates on the terminal block and the terminal support block, specifically as follows:

[0032] First, align the limiting block on the protective cover with the buffer groove, and then align the guide block with the guide groove;

[0033] Under the action of the terminal spring and the electrode plate spring on the terminal, the conductive rod abuts against the conductive plate on the bottom side of the terminal support post;

[0034] Then slide multiple protective covers into the buffer groove one by one;

[0035] Step 4: After multiple protective covers slide into the buffer groove, adjust the spacing between the protective covers and connect them to the support beam using protective cover bolts;

[0036] Step 5: Finally, fix the support beam to the support column by passing the crossbeam fixing bolts through the support beam assembly holes and the column assembly holes.

[0037] The present invention has at least the following beneficial effects:

[0038] 1. The support beam is fixed by the support column, and multiple protective covers are set inside the support beam to increase the impact protection area. They do not affect each other. After the protective cover is hit, the protective cover and the buffer ring on the protective cover are squeezed. The rubber buffer ring and foam buffer ring on the buffer ring play a certain pressure relief role. Therefore, it can improve the impact protection performance of the device and extend the service life of the device.

[0039] 2. The metal buffer component is internally fixed with a U-shaped metal ring and a metal connecting rod. The U-shaped metal ring and the metal connecting rod are made of metal and have a certain tension. When the protective cover is impacted, the buffer ring is squeezed. When the buffer ring is squeezed, the U-shaped metal ring and the metal connecting rod inside the rubber buffer ring deform under the force, and squeeze the supporting beam through the foam buffer ring, rather than squeezing the supporting beam directly. Therefore, it can improve the service life of the supporting beam. Once the force is released, the buffer ring will return to its original shape under the action of the metal buffer component. This makes it easy to maintain and replace the buffer ring, and at the same time, it greatly improves the overall anti-collision performance of the supporting beam.

[0040] 3. After the protective cover slides into the support beam, the conductive rod on the terminal block abuts against the conductive plate under the action of the electrode plate spring. After the conductive plate is energized, it can establish a communication connection with the conductive rod on the terminal block. The outer side of the protective cover is equipped with a path indicator light fixed inside the indicator light slot. The path indicator light is electrically connected to the conductive rod on the terminal block. Therefore, after the conductive plate is energized, the path indicator light can work normally. Multiple path indicator lights on multiple protective covers are set in parallel without affecting each other, improving the flexibility of use. The path indicator light can guide pedestrians and vehicles, avoid accidents, and improve the safety of use.

[0041] 4. The magnet connection assembly is connected in parallel with the speaker and alarm indicator. When the first and second neodymium magnets are in contact, the speaker and alarm indicator are in a partial short circuit state, and the speaker and alarm indicator cannot work normally. However, once the protective cover is slightly bumped, causing the first and second neodymium magnets to separate, the speaker and alarm indicator on the processing chip will work simultaneously and sound an alarm, which makes it convenient for staff to maintain and care for the protective cover in a timely manner and improves the timeliness of the device.

[0042] 5. As the protective cover deforms upon impact, the terminal support platform will cause the terminal to move and deform, leading to the conductive rod and conductive sheet separating from contact. To prolong the stability of the contact between the conductive rod and the conductive sheet, on the one hand, the protective cover connector is fixedly connected to the terminal support platform through a base fixing spring, which plays a certain buffering role. On the other hand, the terminal is slidably mounted on the terminal support platform, and is compressed by the terminal spring, further improving the stability of the conductive rod and conductive sheet. Moreover, the base fixing spring is fixed through the protective cover connector, thus significantly improving the stability of the contact between the conductive rod and the conductive sheet, ensuring the safety of the construction site, and showing good application prospects.

[0055] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0056] like Figures 1-10As shown, the anti-collision combined guardrail component provided in this embodiment includes a support column 7 and a support beam 1 fixedly installed on the support column 7. By evenly fixing the support column 7 on the construction site, the force is evenly distributed, improving the stability of the support beam 1 and the support column 7. A buffer groove 101 is opened on one side of the support beam 1. A protective cover 2 is installed inside the buffer groove 101. A wiring support column 102 is fixedly installed on the upper side inside the buffer groove 101. A wiring post 4 is fixedly installed on the upper part of the outer side of the protective cover 2. The wiring post 4 is electrically connected to the wiring support column 102. A buffer groove 101 is opened on one side of the support beam 1. Multiple protective covers 2 are slidably installed inside the buffer groove 101. When the support beam 1 is squeezed and collided, the multiple protective covers 2 can buffer the impact respectively, thereby improving the anti-collision function of the guardrail.

[0057] To further enhance the anti-collision function, a buffer ring 3 is installed inside the protective cover 2 and the supporting beam 1. The protective cover 2 is slidably installed inside the buffer groove 101, and the protective cover 2 does not contact the interior of the supporting beam 1. The buffer ring 3 is installed between the protective cover 2 and the supporting beam 1. When the buffer ring 3 is impacted, it can play a certain buffering role, improving the anti-collision function of the guardrail. The buffer ring 3 includes a rubber buffer ring 301 and a foam buffer ring 302 installed inside the rubber buffer ring 301. A metal buffer component 303 is fixedly installed inside the rubber buffer ring 301. The metal buffer component 303 includes a U-shaped metal ring 304 and a metal connecting rod 305. The U-shaped metal ring 304 and the metal connecting rod 305 are fixedly connected by welding. At the same time, the metal buffer component 303... The internal components of the 03 are fixedly equipped with a U-shaped metal ring 304 and a metal connecting rod 305. The U-shaped metal ring 304 and the metal connecting rod 305 are made of metal and have a certain tension. When the protective cover 2 is impacted, it compresses the buffer ring 3. When the buffer ring 3 is compressed, the U-shaped metal ring 304 and the metal connecting rod 305 inside the rubber buffer ring 301 are deformed by the force, and the support beam 1 is compressed through the foam buffer ring 302 instead of being directly compressed. Therefore, the service life of the support beam 1 can be improved. Once the force is removed, the buffer ring 3 will return to its original shape under the action of the metal buffer 303. This makes it convenient to maintain and replace the buffer ring 3, and at the same time, it greatly improves the overall anti-collision performance of the support beam 1.

[0058] Therefore, the support beam 1 is fixed by the support column 7, and multiple protective covers 2 are set inside the support beam 1 to increase the impact protection area and do not affect each other. After the protective cover 2 is hit, the protective cover 2 and the buffer ring 3 on the protective cover 2 are squeezed. The rubber buffer ring 301 and foam buffer ring 302 on the buffer ring 3 play a certain pressure relief role. Therefore, it can improve the impact protection performance of the device and extend the service life of the device.

[0059] Furthermore, to prevent pedestrians and vehicles from colliding with the support beam 1 at night, indicator lights are installed on the protective cover 2. The protective cover 2 is slidably installed inside the buffer groove 101. A protective cover connector seat 202 is fixedly installed on the upper part of the outer side of the protective cover 2. The protective cover connector seat 202 is connected to the terminal support platform 204 through the base fixing spring 203. The terminal 4 is vertically slidably installed on the terminal support platform 204. A protective cover connector seat 202 is installed on each protective cover 2, which means that each protective cover 2 can work independently without affecting each other. Since the protective cover 2 and the support beam 1 will deform accordingly after being hit, the terminal 4 is slidably installed on the terminal support platform 204. The terminal support platform 204 is fixed on the protective cover connector seat 202 through the base fixing spring 203. The terminal 4 will deform accordingly with the deformation of the protective cover 2, and there will be no jamming, thus improving the service life of the terminal 4.

[0060] Meanwhile, the upper end of the terminal 4 is provided with symmetrically distributed electrode slots 401. A conductive rod 403 is installed inside the electrode slot 401. The conductive rod 403 is fixed inside the electrode slot 401 by an electrode spring 402. After the 2 is slid into the buffer groove 101, the conductive rod 403 on the terminal 4 provides a certain buffering effect under the action of the electrode spring 402, while ensuring electrical connection. The inner... A conductive sheet 11 is fixedly installed in the part, and the conductive sheet 11 abuts against and is electrically connected to the wiring support post 102. The conductive sheet 11 is electrically connected to an external power source through a wire. The wiring support post 102 is fixedly installed inside the support beam 1, and the conductive sheet 11 is installed in the middle of the wiring support post 102. That is to say, after the protective cover 2 slides into the interior of the support beam 1, the conductive rod 403 on the wiring post 4 abuts against the conductive sheet 11 under the action of the electrode spring 402. After the conductive sheet 11 is energized, it can establish a communication connection with the conductive rod 403 on the wiring post 4.

[0061] After the conductive rod 403 establishes a communication connection with the conductive sheet 11, an indicator light slot 206 is provided on the outer side of the protective cover 2. A path indicator light 10 is fixedly installed inside the indicator light slot 206. The path indicator light 10 is electrically connected to the conductive rod 403. The path indicator light 10 is fixed inside the indicator light slot 206 on the outer side of the protective cover 2. The path indicator light 10 is electrically connected to the conductive rod 403 on the terminal 4. Therefore, after the conductive sheet 11 is energized, the path indicator light 10 can work normally. Multiple path indicator lights 10 on multiple protective covers 2 are set in parallel and will not affect each other, improving the flexibility of use. The path indicator light 10 can guide pedestrians and vehicles, avoid accidents, and improve the safety of use.

[0062] Furthermore, such as Figure 1 , Figure 9 as well as Figure 10 As shown, to facilitate maintenance and upkeep of the support beam 1, a neodymium magnet connecting block 405 is fixedly installed between the two electrode slots 401. A magnet connecting assembly 5 is installed between the neodymium magnet connecting block 405 and the support beam 1. The magnet connecting assembly 5 includes a first neodymium magnet 501 and a second neodymium magnet 502. The first neodymium magnet 501 is fixedly installed inside the support beam 1, and the second neodymium magnet 502 is fixedly installed on the upper side of the neodymium magnet connecting block 405. The first neodymium magnet 501 and the second neodymium magnet 502 are electrically connected. The first neodymium magnet 501 on the magnet connecting assembly 5 is installed on the support beam 1 and electrically connected to the conductive sheet 11. The second neodymium magnet 502 is fixedly installed on the terminal 4 and electrically connected to the conductive rod 403. The contact surfaces of the first neodymium magnet 501 and the second neodymium magnet 502 have opposite magnetic properties. The magnet connecting assembly 5 has two specific functions:

[0063] Firstly, based on the interaction force between the magnetic poles, the conductive rod 403 on the terminal 4 is prevented from detaching from the conductive sheet 11 on the terminal support post 102, thus avoiding poor contact of the path indicator light 10 and improving the stability of the conductive rod 403 and the conductive sheet 11.

[0064] Secondly, a processing chip 9 is fixedly installed on the upper side of the supporting beam 1. The conductive sheet 11 is electrically connected to the processing chip 9. A speaker 901 is fixedly installed on the upper end of the processing chip 9, and an alarm indicator light 902 is fixedly installed on the upper end of the speaker 901. The speaker 901 and the alarm indicator light 902 are connected in parallel and then connected in parallel with the path indicator light 10. The first neodymium magnet 501 and the second neodymium magnet 502 are electrically connected. Moreover, the magnet connecting assembly 5 is connected in parallel with the speaker 901 and the alarm indicator light 902 and is connected with a resistor R. That is to say, the magnet connecting assembly 5 and the speaker are connected in parallel. The speaker 901 and the alarm indicator 902 are connected in parallel. When the first rubidium magnet 501 and the second rubidium magnet 502 are in contact, the speaker 901 and the alarm indicator 902 are in a state of partial short circuit, and the speaker 901 and the alarm indicator 902 cannot work normally. However, once the protective cover 2 is slightly bumped, causing the first rubidium magnet 501 and the second rubidium magnet 502 to separate, the speaker 901 and the alarm indicator 902 on the processing chip 9 will work simultaneously to sound an alarm, which makes it convenient for staff to maintain and care for the protective cover 2 in a timely manner and improves the timeliness of the device.

[0065] Additionally, a resistor R is connected after the magnet connecting assembly 5 is connected in parallel with the speaker 901 and the alarm indicator 902. The purpose of connecting the resistor is to prevent a partial short circuit in the speaker 901 and the alarm indicator 902 from causing a short circuit in the entire circuit, thereby improving safety. A resistor R is connected in series with the path indicator 10. G Connect a resistor R in series with the path indicator light 10. G When the light intensity is high during the day, the path indicator light 10 is in the off state, and at night it is in the closed state, thus effectively saving power resources.

[0066] Furthermore, such as Figure 1 and Figure 6 As shown, the upper end of the terminal 4 is provided with symmetrically distributed guide grooves 404, and the support beam 1 is fixedly provided with symmetrically distributed guide blocks 105. The guide blocks 105 are slidably disposed inside the guide grooves 404. The guide blocks 105 on the support beam 1 are slidably disposed inside the guide grooves 404, which serves to limit the terminal 4 and improve the stability of the terminal 4 operation.

[0067] Meanwhile, a terminal spring 407 is provided between the terminal 4 and the terminal support platform 204, and a terminal limiting block 406 is fixedly provided at the bottom of the terminal 4. If the terminal support platform 204 is fixedly provided on the protective cover 2, the terminal support platform 204 will drive the terminal 4 to move and deform after the protective cover 2 is impacted and deformed, thereby causing the conductive rod 403 to disengage from the conductive sheet 11. In order to prolong the stability of the contact between the conductive rod 403 and the conductive sheet 11, on the one hand, the protective cover connector 202 is fixedly connected to the terminal support platform 204 through the base fixing spring 203, which plays a certain buffering role. On the other hand, the terminal 4 is slidably provided on the terminal support platform 204 and squeezed by the terminal spring 407, which further improves the stability of the contact between the conductive rod 403 and the conductive sheet 11. Moreover, the base fixing spring 203 is fixed through the protective cover connector 202, so it can greatly improve the stability of the contact between the conductive rod 403 and the conductive sheet 11.

[0068] Furthermore, such as Figure 1 , Figure 4 , Figure 7 as well as Figure 10 As shown, the protective cover 2 has a C-shaped structure. Limiting blocks 201 are connected to both ends of the protective cover 2. The limiting blocks 201 are slidably disposed inside the buffer groove 101. The limiting blocks 201 on the protective cover 2 serve a certain guiding and limiting function. The limiting blocks 201 do not contact the interior of the buffer groove 101, which is also to improve the buffering capacity. Several evenly distributed nut joints 205 are fixedly installed on one side of the protective cover 2 near the supporting beam 1. Several evenly distributed supporting beam assembly holes 106 are opened on the supporting beam 1. The nut joints 205 are internally connected by threads. The protective cover bolt 6 passes through the support beam assembly hole 106, and a bolt guide spring 601 is provided between the protective cover bolt 6 and the support beam 1. After the protective cover 2 slides into the interior of the support beam 1, in order to fix the protective cover 2, the protective cover bolt 6 passes through the support beam assembly hole 106 and is threadedly connected to the nut joint 205 on the protective cover 2. At the same time, the bolt guide spring 601 is fixedly provided on the protective cover bolt 6. When the protective cover 2 is hit, the protective cover 2 can move slightly in the horizontal direction and then return to the initial position, thereby improving the overall anti-collision capability.

[0069] The support column 7 has a column assembly hole 701 corresponding to the support beam assembly hole 106. A crossbeam fixing bolt 8 is fixedly installed inside the column assembly hole 701. The crossbeam fixing bolt 8 passes through the support beam assembly hole 106 and the column assembly hole 701 and fixes the support crossbeam 1 and the protective cover 2. The column assembly hole 701 on the support column 7 also corresponds to the support beam assembly hole 106 on the support crossbeam 1. The structure is simple, which improves the scope of use and flexibility. The support crossbeam 1 is fixed to the support column 7 by the crossbeam fixing bolt 8, which improves the overall stability of the support crossbeam 1.

[0070] like Figures 1-10 As shown, the connection method of the anti-collision combined guardrail component provided in this embodiment includes the following steps:

[0071] Step 1: First, fix the support columns 7 on both sides of the construction site and secure the support columns 7.

[0072] Step 2: The rubber buffer ring 301 is processed by injection molding, and the foam buffer ring 302 is fixedly installed inside the rubber buffer ring 301 to complete the installation of the buffer ring 3;

[0073] Step 3: Slide the protective cover 2 into the interior of the support beam 1 through one end, and install the terminal 4 and the conductive sheet 11 on the terminal support post 102, specifically as follows:

[0074] First, align the limiting block 201 on the protective cover 2 with the buffer groove 101, and align the guide block 105 with the guide groove 404;

[0075] Under the action of the terminal spring 407 and the electrode plate spring 402 on the terminal 4, the conductive rod 403 abuts against the conductive plate 11 on the bottom side of the terminal support post 102.

[0076] Then slide multiple protective covers 2 into the interior of the buffer groove 101 in sequence;

[0077] Step 4: After the multiple protective covers 2 slide into the buffer groove 101, adjust the spacing between the protective covers 2, and connect the protective covers 2 to the support beam 1 using the protective cover bolts 6;

[0078] Step 5: Finally, fix the support beam 1 to the support column 7 by passing the crossbeam fixing bolt 8 through the support beam assembly hole 106 and the column assembly hole 701.

[0079] In summary, the anti-collision combined guardrail component and its connection method of the present invention fix the supporting beam with supporting columns. Multiple protective covers are set inside the supporting beam, increasing the anti-collision area without affecting each other. After the protective cover is impacted, it and the buffer ring on the protective cover are compressed. The rubber buffer ring and foam buffer ring on the buffer ring play a certain pressure relief role, thus improving both the anti-collision performance and the service life of the device. The metal buffer component has a U-shaped metal ring and a metal connecting rod fixedly installed inside. The U-shaped metal ring and the metal connecting rod are made of metal and have a certain tension. When the protective cover is impacted, it compresses the buffer ring. When the buffer ring is compressed, the rubber buffer ring... The internal U-shaped metal ring and metal connecting rod deform under stress, and the foam buffer ring compresses the supporting beam instead of directly compressing it. This extends the service life of the supporting beam. Once the stress is relieved, the buffer ring returns to its original shape under the action of the metal buffer component, facilitating maintenance and replacement of the buffer ring, while significantly improving the overall impact resistance of the supporting beam. After the protective cover slides into the supporting beam, the conductive rod on the terminal block abuts against the conductive plate under the action of the electrode plate spring. When the conductive plate is energized, a communication connection is established with the conductive rod on the terminal block. The outer side of the protective cover is equipped with a path indicator light fixed inside the indicator light slot. The path indicator light connects to the wiring... The conductive rods on the pillars are electrically connected, so the path indicator lights can work normally after the conductive plates are energized. Multiple path indicator lights on multiple protective covers are connected in parallel, without affecting each other, improving flexibility of use. The path indicator lights can guide pedestrians and vehicles, preventing accidents and improving safety. The magnetic connection assembly is connected in parallel with the speaker and alarm indicator lights. When the first and second neodymium magnets are in contact, the speaker and alarm indicator lights are in a partial short-circuit state, and they cannot work normally. However, if the protective cover experiences a slight impact, causing the first and second neodymium magnets to separate, the speaker and alarm indicator lights on the processing chip will simultaneously activate, sounding an alarm for the convenience of staff. Timely maintenance and upkeep of the protective cover improves the device's timeliness. When the protective cover deforms upon impact, the terminal support platform causes the terminal to move and deform, potentially causing the conductive rod to detach from the conductive sheet. To extend the stability of the contact between the conductive rod and the conductive sheet, the protective cover connector is fixedly connected to the terminal support platform via a base fixing spring, providing a buffering effect. Furthermore, the terminal slides on the terminal support platform, where it is compressed by the terminal spring, further enhancing the stability of the conductive rod and conductive sheet. The base fixing spring is also secured by the protective cover connector, thus significantly improving the stability of the contact between the conductive rod and the conductive sheet, ensuring safety at the construction site, and demonstrating promising application prospects.
