[0064] The names of messages or information exchanged between multiple devices in the embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of such messages or information.

[0065] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0066] refer to Figures 1 to 7 Some embodiments of this application provide a shock-absorbing low-voltage distribution cabinet 100, including: cabinet 110, cable 120 and support column 130.

[0067] The cabinet 110 is used to house and install electrical equipment such as transformers, switching power supplies, and circuit breakers. One end of a rope 120 is fixed to the top of the cabinet 110. A support column 130 secures the end of the rope 120 away from the cabinet 110. Multiple ropes 120 are fixed at different positions on the top of the cabinet 110. For example, the accompanying drawings of this application illustrate an embodiment where the cabinet 110 of the low-voltage switchgear is cuboid, and four ropes 120 are fixed at the four corners of the top of the cabinet 110. Each rope 120 is fixed to a support column 130, so that the cabinet 110 is lifted and suspended between the multiple supports 130 by the multiple ropes 120.

[0068] By adopting this scheme, the cabinet 110 is suspended from the top of the support column 130 using the rope 120. On the one hand, the cabinet 110 does not need to directly contact the ground, and on the other hand, the rope 120 can also provide a certain shock absorption effect for the cabinet 110 through its own tension. At the same time, the support column 130 supports and fixes the rope 120. The support column 130 can be set on the outside of the cabinet 110 close to the cabinet 110, or it can be set inside the cabinet 110, which occupies relatively little space. Thus, the shock-absorbing low-voltage distribution cabinet 100 provided in this application has the beneficial effects of good shock absorption effect and small space occupation.

[0069] It is worth noting that the tilt of the cabinet 110 to the ground can be adjusted by adjusting the various cables 120. In some embodiments, the shock-absorbing low-voltage distribution cabinet 100 further includes a connector 140 and a locking member 150.

[0070] The connector 140 is fixedly mounted on the end of the rope 120 away from the cabinet 110 and slidably mounted on the support column 130. For example, the support column 130 has a groove 131, allowing the connector 140 to be inserted into the groove 131 and form a slidable connection with the support column 130. The rope 120 is moved by sliding the connector 140, thereby pulling the cabinet 110 and stabilizing it between the ropes 120. The four corners of the cabinet 110 can be adjusted individually, thus facilitating flexible adjustment of the relative positions of the cabinet 110 in the height direction as needed.

[0071] The locking member 150 is movably mounted on the support column 130, having at least a locked position and a clearance position relative to the support column 130. When the locking member 150 is in the clearance position, it clears the connector 140, allowing the connector 140 to slide relative to the support column 130. When the locking member 150 is in the locked position, it engages with the connector 140 to prevent the connector 140 from sliding relative to the support column 130. In other words, the locking member 150 is used to fix the connector 140 to the support column 130, thereby securing the cables 120 and ensuring the cabinet 110 is stably installed between the cables 120.

[0072] As a specific implementation scheme for adjusting the tilt of the cabinet 110 by cooperating with the connecting member 140 and the locking member 150, the connecting member 140 is provided with a first rack 141. Correspondingly, the locking member 150 is provided with a gear 151 that meshes with the first rack 141. The gear 151 is located in the slide groove 131, rotatably connected to the support column 130, and meshes with the first rack 141 when the locking member 150 is in the locked position and the clearance position. Thus, when the locking member 150 is in the clearance position, the first rack 141 is driven to slide by rotating the gear 151, thereby adjusting the tension of the rope 120 and controlling the tilt of the cabinet 110.

[0073] It should be noted that, since multiple ropes 120 are used to suspend the cabinet 110, when the tension of one rope 120 is adjusted, the other ropes 120 can still stably provide tension to the cabinet 110, thereby ensuring the stability of the cabinet 110 during the adjustment process and preventing the cabinet 110 from falling and being damaged.

[0074] To lock the cable 120, in some embodiments, the connector 140 is further provided with a second rack 142 disposed opposite to the first rack 141. Correspondingly, the locking member 150 also includes a connecting post 152 coaxially fixedly connected to the gear 151.

[0075] The connecting post 152 is slidably mounted on the support post 130 to drive the gear 151 to move between a locked position and a clearance position. When the gear 151 is in the locked position, it simultaneously engages with the first rack 141 and the second rack 142. When the gear 151 is in the clearance position, it disengages from the second rack 142. Specifically, this can be achieved by configuring the thickness of the first rack 141 to be greater than the thickness of the second rack 142. Thus, when the locking member 150 is in the clearance position, the engagement of the gear 151 with the first rack 141 causes the connecting member 140 to slide as the gear 151 rotates. When the locking member 150 is in the locked position, the gear 151 simultaneously engages with the first rack 141 and the second rack 142, restricting its rotation and preventing the connecting member 140 from sliding, thereby locking the rope 120.

[0076] Furthermore, a handwheel 153 can be fixedly installed on the connecting column 152. The handwheel 153 is located outside the slide groove 131 so that the user can hold it to slide the connecting column 152 or to rotate the gear 151.

[0077] In some embodiments, the vibration-damping low-voltage distribution cabinet 100 further includes a fixing member 160 and a support member 170. The fixing member 160 is fixedly disposed only at the top of the cabinet body 110. The support member 170 is fixedly disposed at the top of the support column 130 and forms a rope hole 171 for a cable 120 to pass through. One end of the cable 120 is fixed to the fixing member 160, and the other end passes through the rope hole 171 and is fixed to the connector 140. Thus, the support member 170 guides the extension direction of the cable 120, allowing the cable 120 to pull the cabinet body 110 when the connector 140 slides.

[0078] The support columns 130 can be distributed around the cabinet 110, or they can be integrated into a whole by connecting them with additional components. In some embodiments, the vibration-damping low-voltage distribution cabinet 100 further includes a base 180. The base 180 is located at the bottom of the cabinet 110. The bottom ends of the multiple support columns 130 are respectively connected to the base 180, so that the base 180 supports the multiple support columns 130, thereby connecting the support columns 130 using the base 180.

[0079] This application can improve the buffering effect against external vibrations by further providing more structures at the bottom of the support column 130. In some embodiments, the base 180 is provided with a first buffer cavity 181 for the support column 130 to be inserted. The bottom end of the support column 130 is slidably disposed in the first buffer cavity 181. A sealing element, such as a rubber sealing ring, is fixed to the bottom end of the support column 130, which is not shown in the accompanying drawings of this application. The sealing element fits against the cavity wall of the first buffer cavity 181 to form a seal on the first buffer cavity 181. With the above solution, a mating structure similar to a piston and a pneumatic cylinder is formed between the base 180 and the first buffer cavity 181, thereby reducing the transmission of vibration to the cabinet 110 and improving the shock absorption effect.

[0080] In some embodiments, the vibration-damping low-voltage distribution cabinet 100 further includes a vibration-damping spring 182. The vibration-damping spring 182 is disposed within the first buffer cavity 181. The vibration-damping spring 182 is located between the bottom wall of the first buffer cavity 181 and the support column 130. By providing the vibration-damping spring 182, the vibration damping effect can be further improved, and it also provides additional support force to the support column 130, ensuring a stable connection of the support column 130 to the base 180.

[0081] In some embodiments, the vibration-damping low-voltage distribution cabinet 100 further includes a buffer assembly 190. The buffer assembly 190 is fixedly disposed within a first buffer cavity 181 of the base 180. A second buffer cavity 132 is provided at the bottom end of the support column 130. The buffer assembly 190 is at least partially slidably disposed within the second buffer cavity 132 and is in contact with the cavity wall of the second buffer cavity 132. Through the cooperation of the second buffer cavity 132 and the buffer assembly 190, the second buffer cavity 132 forms a cylinder, further absorbing vibrations when the base 180 is subjected to external vibrations.

[0082] In some embodiments, the buffer assembly 190 includes a mounting member 191 and a flexible contact member 192.

[0083] The mounting component 191 can be fixedly connected to the first buffer cavity 181 by means of threaded connection or other methods. A flexible contact 192 is fixed to one end of the mounting component 191. The flexible contact 192 is made of materials such as rubber or silicone, and is inserted into the second buffer cavity 132 and conforms to the cavity wall of the second buffer cavity 132 to separate at least a portion of the second buffer cavity 132 from the first buffer cavity 181. The flexible contact 192 seals the second buffer cavity 132, and its own plastic deformation also buffers vibrations, thereby further enhancing the absorption and buffering capacity of external vibrations.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
