Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment technology, specifically a power distribution equipment tail accessory fixing device. Background Technology

[0002] Power distribution equipment accessories are auxiliary parts for main equipment (switches, cables, transformers, etc.). Their core function is to ensure the integrity of the installation, operation, protection and connection of the main equipment. For example, when a cable is inserted into a distribution box, a cable clamp is a power distribution auxiliary accessory used to fix the cable. Its core function is to stabilize and limit the cable through the clamping structure to prevent displacement and damage.

[0003] An existing patent (publication number: CN216451103U) discloses an explosion-proof cable junction box for power distribution equipment. This junction box uses a connecting ring to fix the cable, allowing for faster location of damaged cables during repairs, reducing repair time and improving work efficiency. Furthermore, during installation, the fixing ring of the fixing mechanism secures the cable and prevents it from sliding inside the junction box, thus avoiding cable tangling and effectively reducing the workload of maintenance personnel.

[0004] To address the aforementioned issues, while existing patents offer solutions that can secure cables through the use of components such as cable junction boxes, in practice, the existing structures cannot be adjusted to the actual inner diameter of the cable during installation. This not only increases the difficulty of operation but also limits the compatibility with cables of a single inner diameter. This limitation significantly restricts the equipment's compatibility with different cable specifications, reduces the flexibility of application scenarios, and causes inconvenience in installation and construction for multi-specification cable applications. It also affects the overall adaptability and practicality of the equipment. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given the problems existing in the above-mentioned prior art: during the actual installation and fixing process, the existing structure cannot be adjusted according to the actual inner diameter of the cable, which not only increases the difficulty of operation, but also results in the ability to only adapt to cables with a single inner diameter. This limitation greatly restricts the compatibility range of the equipment with different specifications of cables, reduces the flexibility of the application scenario, brings inconvenience to the installation and construction of multi-specification cable application scenarios, and also affects the overall adaptability and practicality of the equipment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A tail accessory fixing device for power distribution equipment includes: an assembly housing, a mounting cavity, a limiting cylinder, and a limiting hole; the mounting cavity is formed inside the assembly housing, the limiting cylinder is fixedly installed on the inner wall of the mounting cavity, and the limiting hole is formed inside the limiting cylinder; the device further includes: A fastening mechanism and a reinforcing mechanism; the fastening mechanism is located inside the lower part of the limiting cylinder, and the reinforcing mechanism is located inside the upper part of the limiting cylinder.

[0009] As a further improvement of this utility model: a locking block is fixedly installed on the outer wall of the support ring, and a locking groove is opened inside the limiting cylinder at the position corresponding to the locking block.

[0010] As a further embodiment of this utility model: a fixing rod is fixedly installed between the connecting cylinder and the support ring, and a rotating block is rotatably connected to one end of the fixing rod that passes through the support ring.

[0011] As a further embodiment of this utility model: a rotating plate is rotatably connected to one side of the top end of the support ring, and an abutment plate is rotatably connected to one end of the rotating plate, and a connecting block is rotatably connected to the other end of the abutment plate.

[0012] As a further embodiment of this utility model: the reinforcement mechanism includes: a sliding plate, a sleeve shell, a delivery pipe, a fixing plate, a water bladder, a locking plate, and a rubber pad. The sliding plate is fixedly installed on the other side of the top of the support ring, and the sleeve shell is sleeved on the outside of the sliding plate.

[0013] As a further embodiment of this utility model: a conveying pipe extends from the inside of the sleeve shell, and a fixing plate is inserted into one end of the conveying pipe; a water bladder is fixedly installed on one side of the fixing plate.

This utility model, through the cooperation of a sliding plate, a sleeve shell, a delivery pipe, a fixing plate, a water bladder, a locking plate, and a rubber pad, can compress a filler composed of silicone oil carrier liquid and core particles such as barium titanate and nano titanium dioxide. This allows the water bladder to adapt to different cable inner diameters and achieve all-round coverage. After the filler is energized and cured, it forms a high-strength and high-stability positioning effect. It can not only firmly lock the cable and completely avoid shaking displacement caused by vibration, external force contact, or long-term use, but also absorb vibration energy through the buffering characteristics of the filler, reduce stress concentration at the connection between the cable and the equipment, reduce cable fatigue loss, and significantly extend the service life of the cable and related components. There is no need to replace the adapter parts, which can quickly meet the positioning needs of cables of different specifications and inner diameters, greatly shorten the installation and commissioning time, improve construction efficiency, and reduce labor costs. At the same time, it avoids equipment failure and safety hazards caused by loose cables, further improving the overall system's operational safety and stability. Attached Figure Description

[0017] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0020] Example 1: Please see Figure 1 - Figure 4 This is the first embodiment of the present invention. This embodiment provides a fixing device for the tail accessory of a power distribution equipment, including: an assembly shell 1, a mounting cavity 2, a limiting cylinder 3, and a limiting hole 4; the mounting cavity 2 is formed inside the assembly shell 1, the limiting cylinder 3 is fixedly installed on the inner wall of the mounting cavity 2, and the limiting hole 4 is formed inside the limiting cylinder 3, and also includes: Fastening mechanism 5 and reinforcing mechanism 6; fastening mechanism 5 is located inside the lower part of the limiting cylinder 3, and reinforcing mechanism 6 is located inside the upper part of the limiting cylinder 3.

[0021] Specifically, the fastening mechanism 5 includes: a connecting cylinder 501, a support ring 502, a locking block 503, a locking groove 504, a fixing rod 505, a rotating block 506, a rotating plate 507, a contact plate 508, and a connecting block 509. The connecting cylinder 501 extends out of the bottom end of the limiting cylinder 3, and the top end of the connecting cylinder 501 is movably connected to the support ring 502.

[0022] Furthermore, by threading the connecting cylinder 501 to the limiting cylinder 3, it is easy to adjust after insertion, thereby actuating the support ring 502 to adjust its position inside the limiting cylinder 3.

[0023] Specifically, a locking block 503 is fixedly installed on the outer wall of the support ring 502, and a locking groove 504 is opened inside the limiting cylinder 3 at the position corresponding to the locking block 503.

[0024] Furthermore, the locking block 503 and the locking groove 504 enable the support ring 502 to slide and engage with the limiting cylinder 3 to maintain the stability of the displacement process.

[0025] Specifically, a fixing rod 505 is fixedly installed between the connecting cylinder 501 and the support ring 502, and a rotating block 506 is rotatably connected to one end of the fixing rod 505 that passes through the support ring 502.

[0026] Furthermore, the connecting cylinder 501 passes through the reserved groove of the support ring 502 via the fixing rod 505, and is slidably engaged by the support ring 502. Thus, when the connecting cylinder 501 is rotated and adjusted to be threadedly connected to the limiting cylinder 3, the support ring 502 can slide along the outside of the cable under the engagement of the locking block 503 and the locking groove 504.

[0027] Specifically, a rotating plate 507 is rotatably connected to one side of the top end of the support ring 502, an abutment plate 508 is rotatably connected to one end of the rotating plate 507, and a connecting block 509 is rotatably connected to the other end of the abutment plate 508.

[0028] Furthermore, the sliding of the support ring 502 allows the rotating plate 507 and the contact plate 508 to rotate, and the angle can be adjusted in conjunction with the connecting block 509 to abut against the cable, thereby achieving a clamping effect. The insertion position of the connecting cylinder 501 can be adjusted according to the inner diameter of the cable, thereby achieving clamping and positioning.

[0029] In use, the assembly shell 1 is fixedly connected to the power distribution cabinet of the power distribution equipment and communicates with the mounting cavity 2. After the cable passes through the limiting hole 4 and the limiting cylinder 3, it connects with the electrical components of the power distribution cabinet. The adjustment operation can be completed by rotating the connecting cylinder 501 through the threaded engagement of the connecting cylinder 501 and the limiting cylinder 3. The connecting cylinder 501 is rotatably connected to the support ring 502 with the help of the fixed rod 505 and the rotating block 506, which can ensure that the support ring 502 remains stable when adjusting the connecting cylinder 501. At the same time, the sliding engagement of the locking block 503 and the locking groove 504 further ensures the smoothness of the adjustment process. When the support ring 502 is displaced, it will drive the rotating plate 507, the contact plate 508 and the connecting block 509 to rotate and adjust the angle, thereby clamping and positioning the cable from the outside. In addition, the screwing distance of the connecting cylinder 501 can be flexibly adjusted according to the different inner diameters of the cable, effectively improving the applicability of the overall device.

[0030] In summary, by using the threaded connection between the connecting cylinder 501 and the limiting cylinder 3, rotating the connecting cylinder 501, with the help of the fixed rod 505 and the rotating block 506, achieves flexible rotational connection with the support ring 502, effectively preventing the support ring 502 from shifting or shaking when adjusting the connecting cylinder 501, and maintaining a stable state at all times. At the same time, the sliding engagement structure of the locking block 503 and the locking groove 504 further improves the smoothness and accuracy of the adjustment process, eliminating problems such as jamming and shifting during the adjustment process. When the support ring 502 moves with the connecting cylinder 501, it will synchronously drive the support ring 502. The rotating plate 507, the contact plate 508, and the connecting block 509 rotate relative to each other to adjust their angles, ultimately forming a uniform clamp on the cable from the outside. This not only achieves a firm positioning of the cable but also prevents excessive local force from damaging the cable sheath, ensuring the cable's safety. For cables with different inner diameters, the screw-in distance of the connecting cylinder 501 can be flexibly adjusted to achieve precise matching of clamping force and range. The clamping and positioning structure also reduces cable swaying during use, lowers the risk of poor line contact, and further improves the stability and safety of power distribution equipment operation.

[0031] Example 2: Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 This is the second embodiment of the present utility model.

[0032] Specifically, the reinforcement mechanism 6 includes: a sliding plate 601, a sleeve shell 602, a delivery pipe 603, a fixing plate 604, a water bladder 605, a locking plate 606, and a rubber pad 607. The sliding plate 601 is fixedly installed on the other side of the top of the support ring 502, and the sleeve shell 602 is sleeved on the outside of the sliding plate 601.

[0033] Furthermore, a sliding plate 601 is fixed to the outer wall of the support ring 502 and the locking block 503. During the displacement of the support ring 502, the sliding plate 601 can be inserted into the sleeve shell 602 and slide stably along the sleeve shell 602, thereby further improving the stability of the displacement process of the support ring 502.

[0034] Specifically, a delivery pipe 603 extends from the inside of the housing 602, and a fixing plate 604 is inserted into one end of the delivery pipe 603. A water bladder 605 is fixedly installed on one side of the fixing plate 604.

[0035] Furthermore, the casing 602 is filled with silicone oil carrier fluid and core particles such as barium titanate and nano titanium oxide. Under the pressure of the sliding plate 601, it enters the water bladder 605 through the delivery pipe 603, thus adhering to the outer wall of the cable and solidifying after being energized, further improving the limiting and positioning effect on the cable.

[0036] Specifically, a locking plate 606 is fixedly installed on the top of the sliding plate 601, and a rubber pad 607 is embedded in the top of the locking plate 606.

[0037] Furthermore, the rubber gasket 607 improves the overall sealing performance, allowing the sliding plate 601 to push the filling liquid inside the sleeve 602 to flow.

[0038] When in use, the displacement of the support ring 502 can drive the sliding plate 601 to slide along the slot 504 inside the sleeve shell 602, and push the rubber pad 607 through the locking plate 606 to improve the sealing performance. It can squeeze the filler composed of silicone oil carrier liquid and core particles such as barium titanate and nano titanium oxide. The filler flows into the water bladder 605 after passing through the fixed plate 604 through the delivery pipe 603, and allows the water bladder 605 to fit and cover the cable according to the inner diameter. After the filler is energized and cured, the cable can be positioned to prevent it from shaking. It is suitable for positioning cables with different inner diameters.

[0039] In summary, when the support ring 502 is displaced, it will drive the sliding plate 601 to slide smoothly along the slot 504 inside the sleeve shell 602. The locking plate 606 will precisely push the rubber pad 607 to fit tightly, greatly improving the sealing performance of the structural connection and effectively isolating external dust, moisture and other impurities from intruding. At the same time, it will squeeze the filler composed of silicone oil carrier liquid and core particles such as barium titanate and nano titanium oxide. This filler will be smoothly injected into the water bladder 605 after passing through the fixed plate 604 via the delivery pipe 603. This allows the water bladder 605 to adapt to the inner diameter of different cables, achieving all-round tight fit and coverage. After the filler is energized and cured, it will form a high-strength, high-fit positioning structure. This will not only firmly lock the cable position and completely prevent it from shaking or displacing due to vibration or external force during use, but also reduce cable wear and extend the overall service life of the equipment by utilizing the stability characteristics of the filler. This design can flexibly meet the positioning needs of cables with various inner diameter specifications without the need to replace the adapter parts, significantly improving installation and construction efficiency, while ensuring the stability and reliability of cable connections. It is suitable for cable fixing scenarios under various complex working conditions.
