Description

Technical Field

[0001] This utility model relates to the field of electrical safety equipment technology, and in particular to a surge protector placement base. Background Technology

[0002] A surge protector is a critical electrical safety device used to limit transient overvoltages and discharge surge currents. It is widely used in power systems, communication equipment, building power distribution systems and other fields. Its main function is to quickly introduce overvoltages to the ground in the event of lightning strikes, power grid switching or electrostatic discharge, thereby protecting subsequent electrical equipment and personal safety.

[0003] The existing method of fixing surge protectors to their base mainly relies on the insertion of the surge protector's own electrical circuit pins into the conductive terminals of the base to achieve both mechanical and electrical connections. However, this fixing method still has defects: it relies on the friction between the pins and the socket for fixing and lacks an effective mechanical locking mechanism. During equipment operation, once it encounters external vibration, equipment handling, or long-term thermal expansion and contraction, the surge protector is very likely to loosen or even completely detach from the base, resulting in an interruption of the electrical connection.

[0004] Therefore, in view of the shortcomings of the existing technology, we urgently need a surge protector mounting base to solve this problem. This new type of base should provide a reliable mechanical locking function, which can ensure the stability of the electrical connection and effectively prevent the surge protector from being accidentally dislodged under vibration or external force, thus significantly improving the stability of the installation, the safety of use and the convenience of maintenance. Utility Model Content

[0005] The purpose of this invention is to provide a surge protector mounting base, which solves the problem that the existing technology relies mainly on the surge protector's own electrical circuit pins being inserted into the conductive terminals of the base to achieve both mechanical and electrical connections. However, this fixing method still has defects: it relies on the friction between the pins and the socket for fixing, lacks an effective mechanical locking mechanism, and during equipment operation, once it encounters external vibration, equipment handling, or long-term thermal expansion and contraction, the surge protector is very likely to loosen or even completely detach from the base, leading to the interruption of electrical connection.

[0006] To achieve the above objectives, this utility model provides a surge protector placement base, including a base and two surge protectors placed on top of the base. Each of the two surge protectors has a movable plate on one side and a fixed plate on the other side. The top of the base has horizontal adjustment structures that cooperate with the two movable plates on both sides. One side of the fixed plate and the movable plate has an inclined surface, and the top of each inclined surface has several guide structures that contact the surge protectors. The base has receiving grooves on the inner top of both sides. One side of the surge protector is connected to a vertical plate through a connecting plate. A wedge block is fixedly connected to the bottom of the vertical plate. Both sides of the top of the base have through grooves that are adapted to the wedge block and communicate with the receiving grooves. A wedge block 2 that cooperates with the wedge block 1 is provided inside the through groove. The bottom of the wedge block 2 is fixedly connected to the vertical plate 2. The side wall of the vertical plate 2 is connected to the inner wall of the receiving groove through an elastic reset structure.

[0007] Preferably, the base has two symmetrical horizontal grooves at the top center. The horizontal adjustment structure includes two sliding blocks slidably connected inside the horizontal grooves and two lead screws rotatably connected inside the horizontal grooves. The sliding blocks and lead screws are threaded together.

[0008] Preferably, one end of the lead screw rotates through the side wall of the base and is connected to an adjustment handle, and the sliding block is bolted to the moving plate.

[0009] Preferably, one side of the inclined surface has several vertical grooves, and the guide structure includes several guide wheels that are rotatably connected inside the vertical grooves via a rotating shaft.

[0010] Preferably, the elastic reset structure includes a reset spring and a damper that are connected together on one side of the second vertical plate and the side wall of the receiving groove, and a pull rod is connected to the other side of the second vertical plate.

[0011] Preferably, one end of the pull rod slides through the side wall of the receiving groove and is connected to a pull rod handle, and the bottom of the second vertical plate is slidably connected to the inner bottom of the receiving groove.

[0012] This utility model discloses a surge protector placement base: By incorporating a linkage locking mechanism within the base, consisting of a wedge block, a second wedge block, a first vertical plate, a second vertical plate, an elastic reset structure, and a receiving groove, the surge protector automatically locks itself during insertion using a self-locking principle on an inclined plane. This significantly enhances the mechanical connection strength between the surge protector and the base, maintaining a stable connection even under severe vibration or frequent temperature changes, preventing accidental detachment, and improving the safety and reliability of the system operation. Simultaneously, a guide structure is located at the top of the inclined planes of the fixed plate and the movable plate, providing excellent guidance for the surge protector during installation and reducing... The reduced difficulty and risk of mis-insertion during plugging and connecting improves assembly accuracy and efficiency. Furthermore, adjustable horizontal adjustment structures on both sides of the base drive the moving plate for lateral adjustment, forming a clamping structure adaptable to surge protectors of different thicknesses, enhancing the base's versatility and adaptability. This makes it suitable for quick replacement and maintenance of various product models. During disassembly, the interaction between the inclined surfaces of wedge one and wedge two during their reverse movement, along with the rebound force of the elastic reset structure, automatically resets the locking components, allowing the surge protector to be easily removed without manual unlocking. This significantly improves maintenance convenience and reduces operating costs. Attached Figure Description

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Example 1: Please refer to Figure 1-4 As shown, a surge protector placement base in this embodiment includes a base 1 and two surge protectors 18 placed on top of the base 1. Each of the two surge protectors 18 has a movable plate 2 on one side and a fixed plate 4 on the other side. The top two sides of the base 1 are provided with horizontal adjustment structures that cooperate with the two movable plates 2. The fixed plate 4 and the movable plate 2 are provided with inclined surfaces on one side. Each inclined surface has several guide structures that contact the surge protector 18 at the top. The base 1 has a receiving groove 8 on the inner top of both sides. The surge protector 18 is connected to a vertical plate 11 on one side through a connecting plate 5. A wedge block 12 is fixedly connected to the bottom of the vertical plate 11. Both sides of the top of the base 1 have through grooves that are adapted to the wedge block 12 and communicate with the receiving groove 8. A wedge block 2 13 that cooperates with the wedge block 12 is provided inside the through groove. A vertical plate 2 14 is fixedly connected to the bottom of the wedge block 2 13. The side wall of the vertical plate 2 14 is connected to the inner wall of the receiving groove 8 through an elastic reset structure.

[0021] When it is necessary to install the surge protector 18 onto the base 1, the operator first places the two surge protectors 18 in the designated installation area on the top of the base 1, aligning the electrical circuit pins protruding from their bottoms with the pre-set conductive terminals inside the base 1 and inserting them initially to achieve basic electrical contact and positioning. At this time, a vertical plate 11 is fixedly connected to one side of each surge protector 18 via a connecting plate 5. A wedge block 12 extends from the bottom of the vertical plate 11. The wedge block 12 is located in the through slots opened on both sides of the top of the base 1 and is arranged opposite to a second wedge block 13 set in the through slot, with their inclined surfaces facing each other. During the downward pressing of the surge protector 18, the inclined surfaces on the fixed plate 4 and the movable plate 2 on both sides will contact the guide structures above their respective inclined surfaces. These guide structures play a guiding role, effectively preventing the surge protector 18 from being misaligned or damaged due to offset during insertion, ensuring a smooth and stable insertion. Simultaneously, depending on the specific thickness of the installed surge protector 18, the movable plate 2 on one side can be driven to approach the surge protector 18 horizontally by adjusting the horizontal adjustment structures on both sides of the base 1, while the fixed plate 4 on the other side... The position remains unchanged, thus forming an effective clamping and limiting of the surge protector 18 in the left and right directions, preventing it from swaying laterally. As the surge protector 18 continues to apply downward pressure, the vertical plate 11 drives the wedge block 12 to move downward synchronously. The inclined surface of the wedge block 12 slides relative to the corresponding inclined surface of the lower wedge block 13. Since the bottom of the wedge block 13 is connected to the vertical plate 14, and the side wall of the vertical plate 14 is connected to the inner wall of the receiving groove 8 inside the base 1 through the elastic reset structure, under the action of the inclined surface thrust, the wedge block 13 is forced to overcome the elastic force provided by the elastic reset structure and move laterally in the through groove, completing the movement. The unlocking and clearance action before locking; after the surge protector 18 is fully inserted, its electrical circuit pins are deeply embedded in the conductive terminals of the base 1, achieving a stable and reliable electrical connection. At this time, the wedge block 12 stops moving down, and the wedge block 13 reaches a new equilibrium state after the lateral displacement is completed, and is no longer subjected to continuous thrust. The elastic reset structure is still in a compressed or stretched state, storing a certain amount of elastic potential energy to provide automatic reset power for subsequent disassembly. At the same time, the moving plate 2 has completed the clamping action of the surge protector 18, and together with the fixed plate 4, it forms a constraint on both sides, further enhancing the overall installation stability.To remove surge protector 18, simply apply upward force to pull it out. At this time, vertical plate 11 and wedge block 12 move upwards. The inclined surface of wedge block 12 interacts with the inclined surface of wedge block 13 again, but in the opposite direction. During this reverse movement, the squeezing relationship between the inclined surfaces causes wedge block 13 to shift laterally again, releasing the energy previously stored in the elastic reset structure. This allows wedge block 13 to slide in the opposite direction under the restoring force and return to its initial position until surge protector 18 is completely detached from base 1. The entire disassembly process requires no additional tools and is simple and efficient.

[0022] Furthermore, two symmetrical horizontal grooves are provided at the top center of the base 1. The horizontal adjustment structure includes two sliding blocks 6 slidably connected inside the horizontal grooves and two lead screws 7 rotatably connected inside the horizontal grooves. The sliding blocks 6 and the lead screws 7 are threadedly engaged. Specifically, through the two symmetrical horizontal grooves provided at the top center of the base 1, the sliding blocks 6 slidably connected inside the horizontal grooves, and the lead screws 7 rotatably connected inside the horizontal grooves and threadedly engaged with the sliding blocks 6, when the position of the moving plate 2 needs to be adjusted, the sliding blocks 6 are driven to reciprocate linearly along the axial direction of the lead screw 7 in the horizontal groove by rotating the lead screw 7, thereby pushing the moving plate 2, which is fixedly connected to the sliding blocks 6, to move laterally. During this process, the threaded engagement between the lead screw 7 and the sliding blocks 6 has a self-locking characteristic, which can maintain a stable position after adjustment. This achieves the effect of precise clamping and positioning of surge protectors 18 of different thicknesses and sizes, improves the adaptability of the base 1 to various specifications of products, and ensures that the clamping force is uniform and controllable, avoiding problems of excessive clamping or loosening caused by manual adjustment.

[0023] Furthermore, one end of the lead screw 7 rotates through the side wall of the base 1 and is connected to an adjustment handle 3. The sliding block 6 is bolted to the moving plate 2. Specifically, through the adjustment handle 3 connected to the side wall of the base 1 and the bolted connection between the sliding block 6 and the moving plate 2, the operator can manually rotate the adjustment handle 3 to drive the lead screw 7 to rotate, thereby moving the sliding block 6 and adjusting the position of the moving plate 2. After adjustment, the sliding block 6 and the moving plate 2 are firmly locked together with bolts. This achieves the effects of facilitating external operation, improving adjustment convenience and connection reliability. At the same time, this structure makes the adjustment process of the moving plate 2 without disassembling other parts, making maintenance and installation more efficient and enhancing the humanized design of the overall structure.

[0024] Furthermore, several vertical slots are provided on one side of the inclined surface. The guiding structure includes several guide wheels 17 rotatably connected inside the vertical slots via a rotating shaft. Specifically, through the arrangement of several vertical slots on one side of the inclined surface and the guide wheels 17 rotatably connected inside the vertical slots via a rotating shaft, when the surge protector 18 is inserted, its sidewall contacts the inclined surface on the fixed plate 4 and the moving plate 2. The guide wheels 17 can roll with the downward pressing action of the surge protector 18, reducing the sliding friction resistance during the insertion process and playing a rolling guiding role. This achieves the effects of reducing insertion force, preventing scratches on the equipment surface, and improving centering accuracy. At the same time, multiple guide wheels 17 can provide continuous and stable guiding support for the surge protector 18, effectively avoiding problems such as pin damage or poor contact caused by skewed insertion.

[0025] Furthermore, the elastic reset structure includes a reset spring 15 and a damper 16 connected together on one side of the vertical plate 14 and the side wall of the receiving groove 8. A pull rod 10 is connected to the other side of the vertical plate 14. Specifically, with the reset spring 15 and the damper 16 connected together on one side of the vertical plate 14 and the side wall of the receiving groove 8, and the pull rod 10 connected to the other side of the vertical plate 14, when the wedge block 12 presses down and pushes the wedge block 13 to move laterally, the vertical plate 14 is forced to compress or stretch the reset spring 15. At the same time, the damper 16 acts as a buffer, slowing down the movement speed and preventing impact damage. When the external force is removed or the disassembly stage begins, the reset spring 15 releases its stored energy to push the vertical plate 14 to reset, while the damper 16 controls the reset speed to avoid excessive bouncing or rebound. This achieves the effect of providing stable elastic restoring force and smooth reset, improving the controllability and safety of locking and unlocking actions, and extending the service life of the structure.

[0026] Furthermore, one end of the pull rod 10 slides through the side wall of the receiving groove 8 and is connected to a pull rod handle 9. The bottom of the vertical plate 14 is slidably connected to the inner bottom of the receiving groove 8. Specifically, through the pull rod handle 9 connected to the side wall of the receiving groove 8 and the slidable connection between the bottom of the vertical plate 14 and the inner bottom of the receiving groove 8, when manual intervention of the locking mechanism is required, the pull rod 10 and the vertical plate 14 connected to it can be driven to slide horizontally in the receiving groove 8 by externally operating the pull rod handle 9, thereby realizing the active lateral movement of the wedge block 13. This, in conjunction with the wedge block 12, completes the pre-unlocking or adjustment action. During this process, the sliding connection between the bottom of the vertical plate 14 and the inner bottom of the receiving groove 8 ensures the stability and guidance of the movement, achieving the effect of facilitating manual adjustment and quick release of the locking state during maintenance and repair, and enhancing the operability and emergency handling capability of the device under special working conditions.

[0027] When it is necessary to install the surge protector 18 onto the base 1, the operator first places the two surge protectors 18 in the designated installation area on the top of the base 1, aligning the electrical circuit pins protruding from their bottoms with the pre-set conductive terminals inside the base 1 and inserting them initially to achieve basic electrical contact and positioning. At this time, a vertical plate 11 is fixedly connected to one side of each surge protector 18 via a connecting plate 5. A wedge block 12 extends from the bottom of the vertical plate 11. The wedge block 12 is located in the through slots opened on both sides of the top of the base 1 and is arranged opposite to a second wedge block 13 set in the through slot, with their inclined surfaces facing each other. At the same time, during the downward pressing of the surge protector 18, the inclined surfaces on the fixed plate 4 and the movable plate 2 set on both sides will interact with their respective... The guide structures above the inclined plane make contact. These guide structures include several guide wheels 17 rotatably connected inside the vertical groove via a rotating shaft. The guide wheels 17 roll as the surge protector 18 is pressed down, reducing sliding friction resistance during insertion and acting as a rolling guide to ensure smooth and stable insertion. Depending on the specific thickness of the surge protector 18 being installed, the horizontal adjustment structures on both sides of the base 1 can be adjusted to drive the moving plate 2 on one side to move horizontally closer to the surge protector 18, while the fixed plate 4 on the other side remains in place. This effectively clamps and limits the surge protector 18 in the left and right directions, preventing it from swaying laterally. Specifically, two phases are provided at the center of the top of the base 1. The symmetrical horizontal grooves and the horizontal adjustment structure include two sliding blocks 6 slidably connected inside the horizontal grooves and two lead screws 7 rotatably connected inside the horizontal grooves and threadedly engaged with the sliding blocks 6. The threaded engagement between the sliding blocks 6 and the lead screws 7 has a self-locking characteristic, which can maintain a stable position after adjustment. One end of the lead screw 7 rotates through the side wall of the base 1 and is connected to an adjustment handle 3. The operator can manually rotate the adjustment handle 3 to drive the lead screw 7 to rotate, thereby moving the sliding blocks 6 and adjusting the position of the moving plate 2. After adjustment, the sliding blocks 6 and the moving plate 2 are firmly locked together with bolts. As the surge protector 18 continues to apply downward pressure, the vertical plate 11 moves the wedge block 12 downwards in sync. The inclined wedge block 12... The surface of the wedge block 13 slides relative to the corresponding inclined surface of the wedge block 13 below. Since the bottom of the wedge block 13 is connected to the vertical plate 14, and the side wall of the vertical plate 14 is connected to the inner wall of the receiving groove 8 inside the base 1 through an elastic reset structure, the elastic reset structure includes a reset spring 15 and a damper 16 connected together on one side of the vertical plate 14 and the side wall of the receiving groove 8. When the wedge block 12 presses down and pushes the wedge block 13 to move laterally, the vertical plate 14 is forced to compress or stretch the reset spring 15. At the same time, the damper 16 plays a buffering role, slowing down the movement speed and preventing impact damage. When the external force is removed or the disassembly stage is entered, the reset spring 15 releases its stored energy to push the vertical plate 14 to reset, and the damper 16 controls the reset speed to avoid jumping or rebounding too quickly.Once the surge protector 18 is fully inserted, its electrical circuit pins are deeply embedded in the conductive terminals of the base 1, achieving a stable and reliable electrical connection. At this point, wedge block 12 stops moving downwards, and wedge block 13 reaches a new equilibrium state after completing its lateral displacement, no longer subjected to continuous thrust. The elastic reset structure remains compressed or stretched, storing a certain amount of elastic potential energy to provide automatic reset power for subsequent disassembly. Simultaneously, the moving plate 2 has completed its clamping action on the surge protector 18, working together with the fixed plate 4 to form constraints on both sides, further enhancing the overall installation stability. If it is necessary to disassemble the surge protector 18, simply apply upward force to pull it out. At this time, the vertical plate 11 and wedge block 12 move upwards, and the inclined surface of wedge block 12 interacts with the inclined surface of wedge block 13 again, but in opposite directions. Conversely, during this reverse movement, the squeezing relationship between the inclined planes causes the second wedge block 13 to undergo lateral displacement again, releasing the energy previously stored in the elastic reset structure. This allows the second wedge block 13 to slide in the reverse direction under the action of the restoring force and return to its initial position until the surge protector 18 is completely detached from the base 1. The entire disassembly process requires no additional tools and is simple and efficient. In addition, one end of the pull rod 10 slides through the side wall of the receiving groove 8 and is connected to the pull rod handle 9. The bottom of the second vertical plate 14 is slidably connected to the inner bottom of the receiving groove 8. When manual intervention of the locking mechanism is required, the pull rod 10 and the connected second vertical plate 14 can be driven to slide horizontally within the receiving groove 8 by externally operating the pull rod handle 9, thereby realizing the active lateral movement of the second wedge block 13, which, together with the first wedge block 12, completes the pre-unlocking or adjustment action.

[0028] The design of the guide wheel 17 reduces the insertion force, prevents scratches on the equipment surface, and improves the centering accuracy; the combination of the lead screw 7, sliding block 6, and adjusting handle 3 achieves precise clamping and positioning, improves the adaptability of the base 1 to various product specifications, and ensures uniform and controllable clamping force; the return spring 15 and damper 16 provide stable elastic restoring force and achieve smooth reset, improving the controllability and safety of locking and unlocking actions and extending the service life of the structure; the pull handle 9 and pull rod 10 facilitate manual adjustment and quick release of the locking state during maintenance and repair, enhancing the operability and emergency handling capability of the device under special working conditions.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
