Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable clamp technology, and more specifically, to cable clamps. Background Technology
[0002] A cable clamp is a component made of one material that holds or clamps another material. It is a type of fastener and is made by joining two halves of the clamp together. Both halves of the clamp are semi-circular rings with their ends bent outwards to form a mounting ear. Cable clamps can fix cables.
[0003] Chinese Patent No. CN218783504U discloses a high-voltage switchgear cable clamp assembly. Its key technical features include: a lower fixing member, an upper fixing member, a connecting structure, a fastening structure, and a fixing structure. The lower fixing member is movably connected to the bottom side of the upper fixing member via the connecting structure. The lower fixing member contains a lower washer, and the upper fixing member contains an upper washer. The fastening structure passes through the center of the upper fixing member's annular surface, and the fixing structure passes through the side of the lower fixing member. By providing washers to the high-voltage switchgear cable clamp assembly, the edges of the clamp assembly can be protected. The fastening structure solves the problems of existing high-voltage switchgear cable clamp assemblies where friction between the cable and the edge during cable entry and exit causes external damage, and where the inability to secure the cable leads to collisions between cables or between the cable and the clamp, causing clamp damage.
[0004] The above solution uses an upper and lower washer structure to solve the problem of external cable damage caused by friction between the clamp and the cable edge. However, existing cables are exposed to wind and rain, which shortens the service life of the upper and lower washers and requires frequent replacement. In addition, the clamp is prone to bending and deformation over time when exposed to wind. Therefore, a new solution is needed to solve this problem. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cable clamp.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cable clamp, including an upper clamp and a lower clamp, both of which are fixedly connected to a baffle plate. A sliding plate is slidably connected in the baffle plate. A reinforcing bar is fixedly connected to the inner side of the sliding plate near the baffle plate. A limiting hole is opened inside the baffle plate, and the reinforcing bar is inserted into the limiting hole.
[0007] By adopting the above technical solution, the above structure can ensure that when the cable sways left and right due to strong winds, the reinforcing bar is inserted into the limiting hole, thereby increasing the rigidity between the upper and lower clamps and reducing the deformation or bending of the upper and lower clamps caused by strong winds.
[0008] The present invention is further configured such that: an upper fixing block is fixedly connected to the left and right sides of the upper clamp, a lower fixing block is fixedly connected to the left and right sides of the lower clamp, a bolt is provided between the lower fixing block and the upper fixing block, and a washer is provided between the bolt and the upper fixing block.
[0009] By adopting the above technical solution, when the upper and lower clamps are used to secure the cable, the structure can stably secure the upper and lower clamps through the cooperation of bolts and washers, thereby achieving the function of securing the cable to its foundation.
[0010] The present invention is further configured such that: a silicone rubber is fixedly connected to the lower clamp, both sides of the silicone rubber are fixedly connected to the sliding plate, and a snap-fit buckle is provided at the end of the sliding plate.
[0011] By adopting the above technical solution, not only can silicone protect the cable and reduce friction between the cable and the upper and lower clamps, but the sliding plate can also shield the silicone, reducing rainwater corrosion and thus improving its service life. Furthermore, the opposite arrangement of the snap-fit buckles on the upper and lower clamps ensures that they can engage with each other when the upper and lower clamps are connected, facilitating subsequent sliding of the sliding plate.
[0012] The present invention is further configured such that: a sliding groove is provided inside the baffle plate, and the sliding plate and the sliding groove are slidably connected.
[0013] By adopting the above technical solution, the setting of the above-mentioned reinforcing bars and limiting holes is to improve the strength between the upper and lower clamps when encountering windy weather, thereby reducing the possibility of deformation of the upper and lower clamps.
[0014] The present invention is further configured such that bolts and washers are provided on both the left and right sides of the upper clamp, and holes for bolts to pass through are provided on both the lower fixing block and the upper fixing block.
[0015] The present invention is further configured such that: both the sliding plate and the silicone are arc-shaped, the sliding plate is made of polyurethane, and the silicone is I-shaped.
[0016] The present invention is further configured such that: the reinforcing bars on the sliding plate are configured in five groups, and the limiting holes opened in the baffle plate are configured in five groups, and the five groups of reinforcing bars and the five groups of limiting holes are mutually compatible.
[0017] The present invention is further configured such that the baffle plate, sliding plate, silicone, snap fastener, sliding groove, reinforcing bar and limiting hole on the lower clamp are synchronously provided on the upper clamp.
[0018] In summary, this utility model has the following beneficial effects:
[0019] 1. By using baffles, sliding plates, and silicone sealant, the silicone sealant can protect the cable when it encounters strong winds, reducing friction between the cable and the upper and lower clamps. Furthermore, the baffles and sliding plates are located on both sides of the silicone sealant, which can shield it, reduce rainwater contact with the silicone sealant, improve its service life, and reduce the frequency of silicone sealant replacement.
[0020] 2. By setting up baffles, sliding plates, reinforcing bars, and limiting holes, the sliding plates can slide within the baffles when the upper and lower clamps encounter strong winds, and drive the reinforcing bars to be inserted into the limiting holes, thereby increasing the strength of the upper and lower clamps and reducing the possibility of deformation of the upper and lower clamps.

[0028] Please refer to the embodiments of this utility model. Figures 1 to 6The cable clamp includes an upper clamp 1 and a lower clamp 2. A baffle plate 7 is fixedly connected to the lower clamp 2. A sliding plate 8 is slidably connected to the baffle plate 7. A reinforcing bar 12 is fixedly connected to the inner side of the sliding plate 8 near the baffle plate 7. A limiting hole 13 is opened inside the baffle plate 7. The reinforcing bar 12 is inserted into the limiting hole 13. The baffle plate 7, sliding plate 8, silicone 9, snap fastener 10, sliding groove 11, reinforcing bar 12 and limiting hole 13 on the lower clamp 2 are set synchronously with those on the upper clamp 1. In this embodiment, the width of the reinforcing bar 12 is slightly larger than the width of the limiting hole 13, so as to facilitate the insertion of the reinforcing bar 12 into the limiting hole 13 to reinforce the upper clamp 1 and the lower clamp 2 and reduce the damage to the upper clamp 1 and the lower clamp 2 in windy weather.
[0029] The following describes the connection structure between the upper clamp 1 and the lower clamp 2. Please refer to the following instructions. Figures 1 to 2 The upper clamp 1 is fixedly connected to the left and right sides with upper fixing blocks 4, and the lower clamp 2 is fixedly connected to the left and right sides with lower fixing blocks 3. Bolts 5 are provided between the lower fixing blocks 3 and the upper fixing blocks 4, and washers 6 are provided between the bolts 5 and the upper fixing blocks 4. Bolts 5 and washers 6 are provided on both the left and right sides of the upper clamp 1. Through holes for bolts 5 are provided on both the lower fixing blocks 3 and the upper fixing blocks 4. In this embodiment, the holes provided on the lower fixing blocks 3 and the upper fixing blocks 4 are adapted to the size of the bolts 5. Moreover, the setting of bolts 5 and washers 6 can reduce the phenomenon of bolts 5 loosening accidentally, because washers 6 can compensate for the dimensional error between bolts 5 and upper fixing blocks 4, improve the connection strength of bolts 5, and make the connection tighter.
[0030] The following details the settings for silicone 9 and how to protect it. Please refer to the documentation. Figures 1 to 3 A silicone rubber 9 is fixedly connected to the lower clamp 2. Both sides of the silicone rubber 9 are fixedly connected to the sliding plate 8. The end of the sliding plate 8 is provided with a snap fastener 10. Both the sliding plate 8 and the silicone rubber 9 are arc-shaped. The sliding plate 8 is made of polyurethane, and the silicone rubber 9 is I-shaped. In this embodiment, both the baffle plate 7 and the sliding plate 8 are made of polyurethane. On the one hand, polyurethane has a certain strength and will not affect the sliding of the sliding plate 8 in the baffle plate 7. On the other hand, it will not cause friction to the cable, reducing the degree of damage to the cable. In addition, the silicone rubber 9 is I-shaped so that it can have deformation space during deformation. The reset of the sliding plate 8 is achieved through the silicone rubber 9. Because the silicone rubber 9 has a self-resetting function, the silicone rubber 9 can reset the sliding plate 8 normally.
[0031] The baffle plate 7 has a sliding groove 11 inside, and the sliding plate 8 is slidably connected to the sliding groove 11. The steel bars 12 on the sliding plate 8 are set in five groups, and the limiting holes 13 in the baffle plate 7 are set in five groups. The five groups of steel bars 12 and the five groups of limiting holes 13 are mutually compatible. In this embodiment, the setting of the five groups of steel bars 12 and the limiting holes 13 is to further improve the strength between the upper clamp 1 and the lower clamp 2, and the setting of the sliding groove 11 is to provide the sliding plate 8 to slide more stably in the baffle plate 7.
[0032] Working principle: First, the worker aligns the upper clamp 1 with the lower clamp 2 and tightens the bolt 5 through the upper fixing block 4 and the lower fixing block 3 to secure the cable placed in the upper clamp 1 and the lower clamp 2. At the same time, during the process of securing the cable in the upper clamp 1 and the lower clamp 2, the ends of the sliding plates 8 set on the upper clamp 1 and the lower clamp 2 will interlock with each other, so that the sliding plates 8 on the upper clamp 1 and the lower clamp 2 form a whole, which facilitates the subsequent sliding of the sliding plates 8 in the baffle plate 7. Also, because silicone 9 is set on both the upper clamp 1 and the lower clamp 2 and surrounds the outer ring surface of the cable, the cable will not have much friction with the upper clamp 1 and the lower clamp 2 when the cable is blown around by strong winds.
[0033] Considering that silicone 9 will have its lifespan reduced if it is exposed to the elements for a long time, baffles 7 and sliding plates 8 are installed on both sides of the upper clamp 1 and the lower clamp 2 to wrap the silicone 9 on the left and right sides, thereby improving the service life of silicone 9.
[0034] Considering that the upper clamp 1 and lower clamp 2 may bend and deform when the cable is secured in strong winds, during the process of securing the cable with the upper clamp 1 and lower clamp 2, the strong winds will cause the upper clamp 1 and lower clamp 2 to sway left and right. The cable will be protected by the silicone 9 and the silicone 9 will be squeezed and deformed. The deformation of the silicone 9 will cause the sliding plate 8 to slide in the sliding groove 11 opened in the baffle plate 7. The sliding of the sliding plate 8 will cause the steel bar 12 to move synchronously. Then the steel bar 12 will be inserted into the limiting hole 13. In this way, when the upper clamp 1 and lower clamp 2 are subjected to strong winds, the steel bar 12 will be inserted into the limiting hole 13, thereby improving the overall strength of the upper clamp 1 and lower clamp 2 and reducing the deformation process of the upper clamp 1 and lower clamp 2.
[0035] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
