[0001] The utility model relates to the technical field of outdoor cable brackets, in particular to a plug-in type basic structure for outdoor cable brackets. Background Art

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. They are all composed of single or multiple strands of wires and an insulation layer. They are used to connect circuits, electrical appliances, etc. Cables used outdoors generally need to be installed using brackets.

[0003] The existing technology mostly adopts a plug-in foundation structure for an outdoor cable bracket disclosed by China Application No. CN202221754161.6. The plug-in foundation structure for the outdoor cable bracket combines the Larsen steel plate with the equipment base. All components can be transported to the site for installation after being processed in advance in the factory, which can greatly shorten the construction period of on-site civil engineering operations and gain golden time for power repairs, and has obvious social and economic benefits.

[0004] In the above technical solution, the Larsen steel plate is embedded in the soil layer by hammering. When it needs to be removed, the pull ring is lifted to lift the Larsen steel plate out of the soil layer. However, due to the setting of the steel base plate and the connecting steel columns, the steel base plate cannot be lifted out of the soil layer by the pull ring by one worker. At least two or more workers are required to operate to remove the Larsen steel plate, which requires too much manpower during disassembly and causes waste of human resources. Utility Model Content

[0005] The utility model aims to solve the problem of excessive manpower being required for disassembly in the prior art, resulting in waste of human resources, and proposes a plug-in basic structure for an outdoor cable bracket.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A pluggable basic structure for an outdoor cable bracket includes a steel base plate, a Larsen steel plate and a connecting steel column. The connecting steel column is provided with an external thread, a driving ring is threadedly connected to the connecting steel column, and four sets of connecting mechanisms are arranged on the driving ring. Four supporting feet that are movably opposed to the ground are slidably sleeved on the steel base plate, and the four supporting feet are connected to the driving ring through the connecting mechanism.

[0008] Preferably, the driving ring is a circular ring structure, the inner wall of the driving ring is provided with an internal thread corresponding to the external thread, and the outer wall of the driving ring is fixedly connected with a driving rod.

[0009] Preferably, the four sets of the connecting mechanisms include four driving sliders slidably sleeved on the driving ring, and a traction rod is connected between each of the four driving sliders and the four support feet.

[0010] Preferably, a driving chute for slidably sleeving the driving slider is formed at the bottom end of the driving ring, and the driving chute is a circular ring structure corresponding to the driving ring.

[0011] Preferably, the upper end of the traction rod is pin-connected to the lower end of the driving slider, and the lower end of the traction rod is pin-connected to the upper end of the support foot.

[0012] Preferably, the support foot is in an L-shaped structure, and four U-shaped blocks for slidably sleeving the support foot are fixedly connected to the steel base plate.

[0013] Compared with the prior art, the present utility model has the following advantages:

[0014] The present utility model can rotate the driving ring and utilize the threaded connection between the driving ring and the connecting steel column, so that the driving ring can drive the support foot to move downward through the traction rod, so as to support the steel base plate, the Larssen steel sheet and the connecting steel column to move upward through the support foot. Compared with the prior art in which the Larssen steel sheet is lifted out of the soil layer by a pulling ring, the technical solution only needs to rotate the driving ring to separate the Larssen steel sheet from the soil layer, and only one staff member is required to work throughout the process, without the need for multiple staff members to cooperate, which helps to reduce the waste of human resources.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Refer to Figures 1-3, A plug-in foundation structure for outdoor cable brackets, including a steel bottom plate 1, a Larsen steel plate 2 and a connecting steel column 3;

[0021] The connecting steel column 3 is provided with an external thread 4. A driving ring 5 is threadedly connected to the connecting steel column 3. The driving ring 5 is a circular ring structure. The inner wall of the driving ring 5 is provided with an internal thread corresponding to the external thread 4. The stability of the driving ring 5 on the connecting steel column 3 can be ensured through the external thread 4 and the internal thread. A driving rod is fixedly connected to the outer wall of the driving ring 5, which facilitates the staff to hold it through the driving rod, helps to improve the comfort of the staff when rotating the driving ring 5. By using the threaded connection between the connecting steel column 3 and the driving ring 5, the driving ring 5 can perform vertical lifting when rotating;

[0022] Four connecting mechanisms are arranged on the driving ring 5. Four support feet 6 that are in movable contact with the ground are slidably sleeved on the steel bottom plate 1, and the four support feet 6 are all connected to the driving ring 5 through the connecting mechanisms. The support feet 6 are L-shaped structures. The horizontal section of the support feet 6 is in movable contact with the ground, and four U-shaped blocks for slidably sleeving the support feet 6 are fixedly connected to the steel bottom plate 1. The vertical section of the support feet 6 is slidably connected to the U-shaped blocks. The U-shaped blocks can guide and limit the support feet 6, which helps to ensure the stability of the support feet 6 when performing vertical lifting;

[0023] It should be noted that: the four connecting mechanisms include four driving sliders 7 slidably sleeved on the driving ring 5. The bottom end of the driving ring 5 is provided with a driving chute for slidably sleeving the driving sliders 7. The driving chute is a circular ring structure corresponding to the driving ring 5. The driving chute can provide a moving space for the driving sliders 7 and guide and limit the driving sliders 7, which helps to ensure the stability of the driving sliders 7 when moving;

[0024] A traction rod 8 is connected between the four driving sliders 7 and the four support feet 6. Through the connection between the driving sliders 7 and the traction rod 8, the traction rod 8 will not cause movement interference when the driving ring 5 rotates;

[0025] The upper end of the traction rod 8 is pin-connected to the lower end of the driving slider 7, and the lower end of the traction rod 8 is pin-connected to the upper end of the support foot 6. The position difference generated when the traction rod 8 deflects can drive the support foot 6 to perform vertical lifting. Since the bottom end of the support foot 6 is in movable contact with the ground and the support foot 6 cannot move downward under force, while the steel bottom plate 1, the Larsen steel plate 2 and the connecting steel column 3 can all move upward, the support foot 6 will support the steel bottom plate 1, the Larsen steel plate 2 and the connecting steel column 3 to move vertically upward when being pulled by the traction rod 8;

[0026] It should be noted that; the specific model and specification of the support foot 6 need to be selected according to the actual specifications of the steel bottom plate 1, the Larsen steel plate 2 and the connecting steel column 3, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated.

[0027] The functional principle of the present utility model can be elaborated through the following operation modes:

[0028] In the extraction stage of the plug-and-play basic structure for the outdoor cable support, the staff needs to rotate the driving rod to drive the driving ring 5 to rotate. Through the adaptation connection between the external thread 4 and the internal thread of the driving ring 5, the driving ring 5 moves vertically downward on the connecting steel column 3. The driving ring 5 drives the traction rod 8 to deflect, and the traction rod 8 drives the support foot 6 to move downward. Since the support foot 6 is in movable contact with the ground and the ground cannot move downward, the working force generated when the traction rod 8 pulls the support foot 6 drives the steel base plate 1, the Larsen steel plate 2 and the connecting steel column 3 to move upward.

[0029] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
