Description

Technical Field

[0001] This utility model relates to the field of metering box technology, and in particular to a quick-adjustment cable clamp for an electricity metering box. Background Technology

[0002] For example, publication number "CN112595868A" discloses a "smart IoT meter box," comprising an integrated box body and a door hinged to the box body at one end. The box body is divided into two areas: a control box and a metering box. The control box contains a transfer device for guiding and fixing cables. The output end of the transfer device has a switch assembly. The cable from the transfer device is led out and connected to a circuit breaker via the switch assembly. The circuit breaker is connected to a data acquisition module. The metering box contains multiple meter bases, each connected to an outgoing switch. The data acquisition module is connected to the power distribution master station system via the Internet of Things. However, in practical applications, the clamps in this type of device cannot be adjusted automatically, and commercially available adjustable clamps cannot be adjusted quickly. Each time, the screw needs to be rotated many times to loosen and tighten, resulting in low installation and disassembly efficiency. Summary of the Invention

[0003] In view of the problem mentioned in the background art that the existing cable clamps cannot be adjusted in size or cannot be adjusted quickly, this utility model provides a quick-adjustment cable clamp for an energy metering box, which can be adjusted according to the actual number and size of cables, while ensuring adjustment efficiency and avoiding the need for the adjustment rod to rotate too many times.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] A quick-release cable clamp for an electricity metering box includes a clamp seat connected to the metering box. The clamp seat includes a groove, an adjusting pressure plate slidably connected within the groove, an adjusting rod connected to the clamp seat, and a quick-release cap detachably connected to the clamp seat. The adjusting rod is threadedly connected to the quick-release cap, and the end of the adjusting rod abuts against the adjusting pressure plate. The side of the adjusting pressure plate away from the adjusting rod abuts against the cable. In existing technologies, electricity metering boxes require the introduction of numerous cables. The size and quantity of these cables vary depending on the operating environment. When the cable clamp is fixed, the groove size inside the clamp seat remains constant. If a large number of cables are required, the clamp seat may not be able to accommodate them all, necessitating a larger clamp seat, which affects installation progress and requires preparing multiple clamp seats of various sizes for easy replacement. Conversely, if only a small number of cables are introduced, the cables may not fill the clamp seat, failing to secure them properly and resulting in loose cable fastening. Therefore, some existing technologies use adjustable clamps. However, these adjustable clamps require the adjustment rod to be continuously turned during use. Since the adjustment rod and the clamp seat are connected by threads, the adjustment rod needs to be continuously turned when there are too many or too few cables until the adjustment rod drives the adjustment plate to just abut against the cable to ensure stable pressure on the cable. Because of the threaded connection, the user needs to turn it continuously until the adjustment plate is moved to the appropriate position by the adjustment rod, which reduces the efficiency of installation, disassembly and adjustment.

[0006] In this application, a quick-release cap is provided on the clamp seat to solve the problem. The quick-release cap can be connected in various ways, including but not limited to snap-fit ​​connection, plug-in connection, and threaded connection. Snap-fit ​​connection, plug-in connection, and threaded connection all adopt a quick-release structure. The threaded connection can use a wide thread pitch to reduce the overall thread width, so that the user can separate the quick-release cap from the clamp seat by rotating it only a few times. The snap-fit ​​connection can use elastic plunger, elastic buckle, etc. to improve the disassembly and assembly efficiency, so that the user can more easily separate the quick-release cap from the clamp seat. Because the adjusting rod and quick-release cap are connected by a thread, the adjusting rod can move flexibly after the quick-release cap separates from the clamp seat. The adjusting rod and quick-release cap move synchronously, and the pressure of the adjusting plate is driven by the pressure of the adjusting rod. After the adjusting rod is separated from the clamp seat by the quick-release cap, the user can quickly adjust the position of the adjusting plate, so that the adjusting plate is not limited by the adjusting rod, greatly improving the adjustment efficiency. After all the cables have passed through, the relative position between the adjusting rod and quick-release cap can be roughly estimated based on the position of the adjusting plate. The quick-release cap is rotated to adjust the position between the adjusting rod and the adjusting rod. Then the quick-release cap is reinstalled on the clamp seat, and the adjusting rod is finally tightened. Since the quick-release cap and adjusting rod can be separated from the clamp seat when adjusting, the quick-release cap can be directly moved to make it rotate quickly by inertia, so as to quickly adjust the relative position of the quick-release cap on the adjusting rod. Compared with the existing technology, which can only turn the adjusting rod on the clamp seat, it is more labor-saving and easier to apply force.

[0007] Preferably, the quick-release cap and the clamp seat are threaded together. The threaded connection between the quick-release cap and the clamp seat better ensures the stability of the connection. When the quick-release cap and clamp seat are threaded together, the quick-release cap is designed with a polygonal shape that facilitates twisting, making it easier to tighten with a wrench. It also reduces the number of turns required for unlocking and locking between the quick-release cap and the clamp seat, allowing for quick disassembly by the operator. It is important to ensure that the tightening direction of the threaded connection between the quick-release cap and the clamp seat is the same as the tightening direction of the adjusting rod and the quick-release cap. That is, when the adjusting rod is tightened clockwise relative to the quick-release cap, the quick-release cap is also tightened clockwise relative to the clamp seat, thus ensuring that the quick-release cap will not loosen relative to the clamp seat when the adjusting rod is tightened.

[0008] Preferably, the clamp seat is provided with a fixing block, and the quick-release cap includes a quick-release groove, which is threadedly connected to the fixing block. The clamp seat is provided with a fixing block, and the fixing block and the clamp seat are fixedly connected, including but not limited to integral molding, welding, etc., while the quick-release cap includes a quick-release groove, and the quick-release groove is threadedly connected to the fixing block, thereby facilitating the installation and removal of the quick-release cap.

[0009] Preferably, the quick-release cap includes a threaded hole communicating with the quick-release slot, and the threaded hole is threadedly connected to the adjusting rod. The quick-release cap has a threaded hole communicating with the quick-release slot, and the threaded hole connects to the adjusting rod. The adjusting rod is connected to the threaded hole, thus establishing a connection between the adjusting rod and the quick-release cap. When the quick-release cap is fixed to the clamp seat, rotating the adjusting rod changes its relative position to the clamp seat, thereby changing the fixing and constraint position of the adjusting pressure plate on the cable. Furthermore, the threaded connection between the quick-release cap and the adjusting rod creates a self-locking mechanism, preventing the adjusting pressure plate from moving the adjusting rod.

[0010] Preferably, the fixing block is provided with a through hole, which is slidably connected to the adjusting rod. The through hole on the fixing block, with its slidable connection to the adjusting rod, ensures that the fixing block only forms a threaded connection with the quick-release cap, without threading a limit on the adjusting rod. Therefore, after the fixing block and quick-release cap are disengaged via the threaded connection, the quick-release cap and adjusting rod can be directly removed from the clamp seat, improving the efficiency of adjusting the position of the adjusting rod. When installing the quick-release cap onto the fixing block, the adjusting rod can also be directly inserted through the through hole. After the quick-release cap and fixing block are connected, only minor adjustments to the adjusting rod are needed, reducing the number of rotations of the adjusting rod on the clamp seat and increasing the degree of freedom in adjustment.

[0011] Preferably, a guide rail is provided on the side wall of the slot, and the adjusting plate includes a groove that is slidably connected to the guide rail. The guide rail on the side wall of the slot corresponds to the groove on the adjusting plate, wherein the shape of the groove matches the shape of the guide rail, thereby allowing the adjusting plate to be confined within the slot and to move along the guide rail within the slot. The extending directions of the guide rail and the groove are parallel to the axis of the adjusting rod.

[0012] Preferably, the clamp seat is provided with a guide hole, and a guide post is connected to the adjusting pressure plate. The guide post and the adjusting pressure plate move synchronously, and the guide post is slidably connected to the guide hole. The guide hole on the clamp seat can mate with the guide post on the adjusting pressure plate, allowing the guide post to slide relative to the clamp seat. This makes the movement of the adjusting pressure plate smoother through the guiding action of the guide post, and also allows the operator to directly drive the adjusting pressure plate by dragging the guide post from outside the clamp seat when the adjusting rod is detached from the clamp seat.

[0013] Preferably, a plurality of guide holes and guide posts are provided, and the guide holes and guide posts are respectively located on both sides of the adjusting rod. Providing multiple guide holes and guide posts, and positioning them on both sides of the adjusting rod, is preferable to symmetrically arranging the guide holes and guide posts on both sides, thereby ensuring the smooth operation and uniform force distribution of the adjusting pressure plate.

[0014] Preferably, a nut is provided at the end of the adjusting rod away from the adjusting pressure plate. The nut at the end of the adjusting rod away from the adjusting pressure plate allows for easy tightening. The nut can be either a cross-shaped or hexagonal nut, depending on the actual usage scenario and requirements; this facilitates tightening of the adjusting rod by the operator.

[0015] Preferably, the metering box is provided with a mounting base, and the clamp seat includes clamp legs connected to the mounting base. The clamp legs partially abut against the mounting base. When the adjusting pressure plate slides to the bottom of the slot, the adjusting pressure plate partially abuts against the mounting base. The mounting base provided on the metering box is used to install the clamp seat. In this application, the clamp legs of the clamp seat only partially abut against the mounting base, so that there is still a part of the mounting base that does not abut against the clamp legs. At the same time, the adjusting pressure plate, which is slidably connected in the clamp seat, can abut against the mounting base when it moves to the bottom of the slot, so that the adjusting pressure plate can abut against the mounting base, thereby limiting the extreme position of the adjusting pressure plate and making it flush with the clamp legs. The adjusting pressure plate is provided with an inner groove structure, so that when the adjusting pressure plate abuts against the mounting base, a gap is still left on the adjusting pressure plate to allow the cable to pass through.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) By setting a quick-release cap and a clamp seat for detachable connection, and setting an adjustment rod connected to the quick-release cap, the clamp seat can adjust the constraint limit of the cable according to the actual number and size of the cable, while ensuring adjustment efficiency and avoiding the need for the adjustment rod to rotate too many times in the clamp seat.

[0018] (2) By setting guide holes and guide columns, the stable movement of the adjusting plate can be controlled. At the same time, by setting guide rails and slides, the adjusting plate can still maintain a relative sliding state on the clamp seat after it is disengaged from the adjusting rod.

[0019] (3) By setting the through hole on the fixing block to be slidably connected to the adjusting rod, the adjusting rod can be directly disengaged from the clamp seat after the quick release cap is removed from the fixing block, which makes it convenient for the adjusting rod to be adjusted in position with the quick release cap alone, thus improving the adjustment efficiency.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Example 1:

[0033] like Figure 1 , 2As shown, a quick-adjustment cable clamp for an electricity metering box includes a clamp seat 1 connected to the metering box. The clamp seat 1 includes a groove 11, an adjusting pressure plate 2 slidably connected in the groove 11, an adjusting rod 3 connected to the clamp seat 1, and a quick-release cap 41 detachably connected to the clamp seat 1. The adjusting rod 3 is threadedly connected to the quick-release cap 41, and the end of the adjusting rod 3 can abut against the adjusting pressure plate 2. The side of the adjusting pressure plate 2 away from the adjusting rod 3 can abut against the cable. In existing technologies, a large number of cables need to be introduced into the electricity metering box. The size and quantity of the introduced cables vary in different usage environments. When the cable clamps are fixed, the size of the slot 11 inside the clamp seat 1 remains unchanged. If a large number of cables need to be introduced into the usage environment, the clamp seat 1 will not be able to accommodate them, and a larger clamp seat 1 needs to be replaced, which will affect the installation progress. In addition, a large number of clamp seats 1 of different models need to be prepared during the installation process for easy replacement. If a small number of cables are introduced, the cables will not be able to fill the interior of the clamp seat 1, and the clamp seat 1 will not be able to fix the cables, resulting in loose cable fixation. Therefore, some existing technologies also use adjustable clamps. However, with such adjustable clamps, the adjusting rod 3 needs to be continuously turned during use. Since the adjusting rod 3 and the clamp seat 1 are connected by threads, when there are too many or too few cables, the adjusting rod 3 needs to be continuously turned until the adjusting rod 3 drives the adjusting pressure plate 2 to just abut against the cable to ensure stable pressure on the cable. Because of the threaded connection, the user needs to turn it continuously until the adjusting pressure plate 2 moves to the appropriate position through the movement of the adjusting rod 3, thus reducing the efficiency of installation, disassembly and adjustment.

[0034] In this application, a quick-release cap 41 is provided on the clamp seat 1 to solve the problem. The quick-release cap 41 can be connected in various ways, including but not limited to snap-fit ​​connection, plug-in connection, and threaded connection. Snap-fit ​​connection, plug-in connection, and threaded connection all adopt a quick-release structure. The threaded connection can use a wide thread pitch to reduce the overall thread width, so that the user can separate the quick-release cap 41 from the clamp seat 1 by rotating it only a few times. The snap-fit ​​connection can use elastic plunger, elastic buckle, etc. to improve the disassembly and assembly efficiency, so that the user can more easily separate the quick-release cap 41 from the clamp seat 1. Since the adjusting rod 3 and the quick-release cap 41 are connected by a thread, the adjusting rod 3 can move flexibly after the quick-release cap 41 is separated from the clamp seat 1. The adjusting rod 3 and the quick-release cap 41 move synchronously, and the squeezing force of the adjusting plate 2 is driven by the pressure of the adjusting rod 3. After the adjusting rod 3 is separated from the clamp seat 1 by the quick-release cap 41, the user can quickly adjust the position of the adjusting plate 2, so that the adjusting plate 2 will not be limited by the adjusting rod 3, and the adjustment efficiency is greatly improved. After all the cables have passed through, the position of the adjusting plate 2 will determine the adjustment efficiency. The relative position between the adjusting rod 3 and the quick-release cap 41 is roughly estimated. The quick-release cap 41 is rotated to adjust the position between it and the adjusting rod 3. Then, the quick-release cap 41 is reinstalled on the clamp seat 1. Finally, the adjusting rod 3 is tightened. Since the quick-release cap 41 and the adjusting rod 3 can be disengaged from the clamp seat 1 when adjusting, the quick-release cap 41 can be directly moved to make it rotate quickly using inertia to quickly adjust the relative position of the quick-release cap 41 on the adjusting rod 3. This method is more labor-saving and easier to apply force than the existing technology that can only turn the adjusting rod 3 on the clamp seat 1.

[0035] like Figure 2 , 4 As shown, the quick-release cap 41 is threadedly connected to the clamp seat 1. The clamp seat 1 has a fixing block 12. The quick-release cap 41 includes a quick-release groove, which is threadedly connected to the fixing block 12. The quick-release cap 41 includes a threaded hole 42 communicating with the quick-release groove, which is threadedly connected to the adjusting rod 3. The fixing block 12 has a through hole 121, which is slidably connected to the adjusting rod 3.

[0036] The quick-release cap 41 and the clamp seat 1 are connected by a threaded connection. This threaded connection ensures better stability of the connection between the quick-release cap 41 and the clamp seat 1. When the threaded connection between the quick-release cap 41 and the clamp seat 1 is implemented, the quick-release cap 41 is designed with a polygonal shape that facilitates twisting, making it easier to tighten with a wrench. Furthermore, the number of turns required for unlocking and locking between the quick-release cap 41 and the clamp seat 1 is reduced, allowing for quick disassembly by the operator. It is necessary to ensure that the tightening direction of the threaded connection between the quick-release cap 41 and the clamp seat 1 is the same as the tightening direction between the adjusting rod 3 and the quick-release cap 41. That is, when the adjusting rod 3 is rotated clockwise relative to the quick-release cap 41, the quick-release cap 41 is also rotated clockwise relative to the clamp seat 1. This ensures that tightening the adjusting rod 3 will not cause the quick-release cap 41 to loosen relative to the clamp seat 1. A fixing block 12 is provided on the clamp seat 1, and the fixing block 12 is fixedly connected to the clamp seat 1, including but not limited to integral molding, welding, etc. The quick-release cap 41 includes a quick-release groove, and the quick-release groove is threadedly connected to the fixing block 12, thereby facilitating the installation and removal of the quick-release cap 41. A threaded hole 42 is provided on the quick-release cap 41, and the threaded hole 42 communicates with the quick-release groove. The threaded hole 42 is connected to the adjusting rod 3. The adjusting rod 3 is connected to the threaded hole 42, thereby establishing a connection between the adjusting rod 3 and the quick-release cap 41. When the quick-release cap 41 is fixed on the clamp seat 1, the relative position of the adjusting rod 3 with respect to the clamp seat 1 is changed by turning the adjusting rod 3, thereby changing the fixed constraint position of the adjusting pressure plate 2 on the cable. Furthermore, the threaded connection between the quick-release cap 41 and the adjusting rod 3 forms a self-locking mechanism, preventing the adjusting pressure plate 2 from moving the adjusting rod 3. A through hole 121 is provided on the fixing block 12, wherein the through hole 121 and the adjusting rod 3 are slidably connected, so that the fixing block 12 is only threadedly connected to the quick-release cap 41, and the adjusting rod 3 is not threadedly limited. Therefore, when the fixing block 12 and the quick-release cap 41 are disconnected through the threaded connection, the quick-release cap 41 and the adjusting rod 3 can be directly removed from the clamp seat 1, which improves the adjustment efficiency of the position of the adjusting rod 3. When the quick-release cap 41 is installed on the fixing block 12, the adjusting rod 3 can also be directly inserted through the through hole 121. After the quick-release cap 41 and the fixing block 12 are connected, only the adjusting rod 3 needs to be finely adjusted, which reduces the number of rotations of the adjusting rod 3 on the clamp seat 1 and improves the degree of freedom of adjustment.

[0037] like Figure 3 As shown, a guide rail 13 is provided on the side wall of the slot 11, and the adjusting pressure plate 2 includes a slide groove 21 that is slidably connected to the guide rail 13. A guide hole 14 is provided on the clamp seat 1, and a guide post 22 is connected to the adjusting pressure plate 2. The guide post 22 and the adjusting pressure plate 2 move synchronously, and the guide post 22 is slidably connected to the guide hole 14.

[0038] A guide rail 13 is provided on the side wall of the slot 11, and a corresponding groove 21 is provided on the adjusting plate 2. The shape of the groove 21 is adapted to the shape of the guide rail 13, so that the adjusting plate 2 can be limited inside the slot 11 and can move along the guide rail 13 in the slot 11. The extension direction of the guide rail 13 and the groove 21 is parallel to the axis of the adjusting rod 3. The guide hole 14 provided on the clamp seat 1 can be connected with the guide post 22 provided on the adjusting plate 2, so that the guide post 22 can slide relative to each other in the guide hole 14. This makes the movement of the adjusting plate 2 smoother through the guiding action of the guide post 22, and also makes it convenient for the operator to drive the adjusting plate 2 directly by dragging the guide post 22 from outside the clamp seat 1 when the adjusting rod 3 is detached from the clamp seat 1.

[0039] like Figure 2 As shown, several guide holes 14 and guide posts 22 are provided, and the guide holes 14 and guide posts 22 are respectively located on both sides of the adjusting rod 3. By providing multiple guide holes 14 and guide posts 22, and positioning them on both sides of the adjusting rod 3, preferably, the guide holes 14 and guide posts 22 on both sides are symmetrically arranged, thereby ensuring the smooth operation and uniform force distribution of the adjusting pressure plate 2.

[0040] like Figure 2 As shown, a nut 31 is provided at the end of the adjusting rod 3 away from the adjusting pressure plate 2. The nut 31 at the end of the adjusting rod 3 away from the adjusting pressure plate 2 can be easily tightened. The nut 31 can be set as a cross-shaped opening or a hexagonal nut 31 structure, which can be set according to the actual use scenario and needs; making it convenient for staff to tighten the adjusting rod 3.

[0041] like Figure 2 , 5 As shown, the metering box is provided with a mounting base 5, and the clamp base 1 includes a clamp support leg 15 connected to the mounting base 5. The clamp support leg 15 partially abuts against the mounting base 5. When the adjusting pressure plate 2 slides to the bottom of the groove 11, the adjusting pressure plate 2 partially abuts against the mounting base 5. The mounting base 5 on the metering box is used to install the clamp base 1. In this application, the clamp support 15 of the clamp base 1 only partially abuts against the mounting base 5, so that there is still a part of the mounting base 5 that does not abut against the clamp support 15. At the same time, the adjusting pressure plate 2, which is slidably connected in the clamp base 1, can abut against the mounting base 5 when it moves to the bottom of the groove 11, so that the adjusting pressure plate 2 can abut against the mounting base 5, thereby limiting the extreme position of the adjusting pressure plate 2 and making it flush with the clamp support 15. The adjusting pressure plate 2 is designed with an inner groove structure, so that when the adjusting pressure plate 2 abuts against the mounting base 5, a gap is still left on the adjusting pressure plate 2 to allow the cable to pass through.

[0042] like Figure 5 As shown, the assembly and operation process of the quick-adjustment cable clamps of the power metering box in this embodiment is as follows: In this embodiment, three cable clamps are respectively set above the inlet hole of the metering box. Each cable clamp includes a clamp seat 1, wherein the clamp seat 1 includes clamp legs 15 set on both sides, and a groove 11 is set between the two clamp legs 15. The metering box is provided with mounting bases 5 at corresponding positions of the three cable clamps. The clamp legs 15 are bolted to the mounting bases 5. An adjusting pressure is slidably connected inside the groove 11 of the clamp seat 1. Plate 2, wherein one side of the adjusting pressure plate 2 is a flat surface and the other side is an arc-shaped groove structure. The flat side abuts against the adjusting column, and the arc-shaped groove side abuts against the cable. Three holes are provided on the end of the clamp seat 1, of which the two holes are guide holes 14. Guide columns 22 are slidably connected in the guide holes 14. The ends of the guide columns 22 are connected to the adjusting pressure plate 2. The adjusting pressure plate 2 and the guide columns 22 are fixedly connected, that is, the movement of the guide columns 22 and the adjusting pressure plate 2 is synchronous. The guide columns 22 on both sides are symmetrically and evenly arranged to ensure To ensure stable sliding of the adjusting pressure plate 2, a fixing block 12 is provided between the two guide holes 14. A quick-release cap 41 is fitted onto the fixing block 12. In this embodiment, the quick-release cap 41 and the fixing block 12 are connected by a thread. A threaded hole 42 is provided on the side of the quick-release cap 41 away from the fixing block 12. The threaded hole 42 is connected to the adjusting rod 3. The adjusting rod 3 includes a screw part connected to the threaded hole 42 and a nut 31 part. In this embodiment, the nut 31 part has a cross-shaped opening. A through hole 121 is provided on the fixing block 12. The through hole 121 connects to... The threaded hole 42 and the slot 11 are connected, and the size of the through hole 121 is larger than that of the threaded hole 42, so that the adjusting rod 3 can be connected to the threaded hole 42 in the screw part without being stuck in the through hole 121, so that the adjusting rod 3 can pass through the through hole 121 smoothly without obstruction; guide rails 13 are provided on both sides of the clamp seat 1 inside the slot 11, and sliding grooves 21 are provided on both sides of the adjusting pressure plate 2. Through the engagement connection between the sliding groove 21 and the guide rail 13, the adjusting pressure plate 2 can slide along the two sides of the clamp seat 1.

[0043] During use, to save storage space, the adjusting plate 2 is placed at the bottom of the slot 11, and the adjusting rod 3 is set to abut against the adjusting plate 2. After the cable clamp is connected to the mounting base 5 with bolts, keeping the adjusting rod 3 still, the quick-release cap 41 is removed from the fixing block 12, allowing the quick-release cap 41 to detach from the fixing block 12, and simultaneously causing the adjusting rod 3 to detach. At this point, the adjusting plate 2 can be moved freely. After all cables are passed through the space between the adjusting plate 2 and the metering box, the adjusting plate 2 is then placed against the electrical... On the cable, estimate the distance between the adjusting pressure plate 2 and the fixed block 12. At this time, adjust the relative position of the detached quick-release cap 41 and the adjusting rod 3. Compared with turning the adjusting rod 3, turning the quick-release cap 41 directly is more efficient. Under low friction, the quick-release cap 41 can be rotated quickly and can be kept rotating by inertia, thereby quickly adjusting the position of the quick-release cap 41 on the adjusting rod 3. After leaving an appropriate length for the adjusting rod 3, connect the quick-release cap 41 to the fixed block 12, and then make fine adjustments to the adjusting rod 3.
