Description

Technical Field

[0001] The utility model relates to the technical field of communication engineering, in particular to a pre-buried base for a communication tower. Background Technique

[0002] As is well known, a communication tower, also known as a communication mast or signal tower, is a building or structure used to support wireless communication equipment and antennas. These towers are usually located on high ground or in vast areas so that signals can cover a wider area. They are used to support various communication services such as mobile communication, broadcasting, wireless Internet, and television relay. The pre-buried base can serve as a support structure for the communication tower. The bottom of the communication tower usually has interfaces and bolts, which can be fixed to the pre-buried base to ensure that the communication tower can be firmly installed on the ground. Therefore, the connection between the pre-buried base and the communication tower lies in providing a support structure to enable the communication tower to stand firmly on the ground and perform its functions.

[0003] However, for traditional pre-buried bases for communication towers, usually when the communication tower is affected by external wind force, mechanical vibration or other environmental factors, the frequencies of these vibrations may match the natural frequencies of the base bolts. This resonance effect will increase the force on the base bolts and cause the bolts to move upward, thereby affecting the overall stability of the communication tower. For this reason, urgent technical improvements are needed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose a pre-buried base for a communication tower. When the pre-buried base for the communication tower is in use, multiple bolts are used to drive the ground nails to move, thereby limiting the bottom plate. By aligning the connecting seat at the lower end of the protective cover with the guiding hole, and then rotating the protective cover, the connecting seat and the clamping block are driven to slide in the annular groove. The clamping block is limited by the positioning block sliding in the positioning groove to prevent the limiting spring from shifting during movement. At this time, the clamping block drives the limiting spring to be compressed under the action of force. When rotated by 90°, the clamping blocks on both sides coincide with the limiting holes. At this time, the limiting spring releases the acting force to drive the clamping block to rebound, so as to be clamped with the limiting holes, which can limit the bolts, ensure that the bolts are firmly fixed on the base, reduce the upward movement or deviation of the bolts, and thus enhance the connection stability between the communication tower base and the ground.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A pre-buried base for a communication tower, including a bottom plate. The middle part of the upper surface of the bottom plate is fixedly connected with a positioning seat.

The upper ends of the limiting springs 19 are each fixedly connected with a clamping block 20.

[0039] Compared with the existing embedded base for communication towers, when this embedded base for communication towers is in use, by rotating the threaded rod 4, it is convenient to drive the limiting backing plate 10 to move. At this time, the hinge rod 9 moves through the movement of the limiting backing plate 10. The slider 6 slides in the sliding groove 5 through the movement of the hinge rod 9. The limiting block 8 slides in the limiting groove 7 to limit the slider 6 to prevent it from falling when sliding. By driving the two ends of the limiting backing plate 10 to approach each other continuously, the lower end of the communication tower is limited, and thus the installation and adjustment process of the communication tower can be made simpler and more convenient, with relatively high practical performance.

[0040] The connecting seats 17 are each slidably connected inside the annular groove 13. By slidably connecting the connecting seats 17 inside the annular groove 13 respectively, it is convenient to adjust the positions of the connecting seats 17. The clamping block 20 is in clamping fit with the limiting hole 15. By the clamping fit of the clamping block 20 and the limiting hole 15, it is convenient to limit the protective cover 16. A positioning hole 3 is provided in the middle of the upper surface of the positioning seat 2. It is convenient to position the communication tower through the positioning hole 3. Sliding grooves 5 are provided on both sides of the front end and the rear end of the positioning seat 2. One side outer wall of the hinge rod 9 far from the center of the bottom plate 1 is each hingedly connected with a slider 6. The sliders 6 are each slidably connected inside the sliding grooves 5. By slidably connecting the sliders 6 inside the sliding grooves 5 respectively, it is convenient to slide along with the movement of the hinge rod 9. The upper end and the lower end of the slider 6 are each fixedly connected with a limiting block 8. Limiting grooves 7 are provided on the top surface and the bottom surface of the sliding groove 5.

[0041] Working principle: When in use, multiple bolts 11 are used to drive the ground nails 12 to move, thereby limiting the bottom plate 1. By aligning the connecting seat 17 at the lower end of the protective cover 16 with the guide hole 14, and then rotating the protective cover 16, the connecting seat 17 and the clamping block 20 are driven to slide in the annular groove 13. The positioning block 22 slides in the positioning groove 21 to limit the clamping block 20 and prevent the limiting spring 19 from shifting during movement. At this time, the clamping block 20 drives the limiting spring 19 to be compressed under the action of force. When rotated by 90°, the two clamping blocks 20 coincide with the limiting holes 15. At this time, the limiting spring 19 releases the acting force to drive the clamping block 20 to rebound, so as to be clamped with the limiting holes 15, which can limit the bolts 11, ensure that the bolts 11 are firmly fixed on the base, reduce the upward movement or deviation of the bolts 11, and thus enhance the connection stability between the communication tower base and the ground. By rotating the threaded rod 4, it is convenient to drive the limiting backing plate 10 to move. At this time, the hinge rod 9 moves through the movement of the limiting backing plate 10. The slider 6 slides in the sliding groove 5 through the movement of the hinge rod 9. The limiting block 8 slides in the limiting groove 7 to limit the slider 6 to prevent it from falling when sliding. By driving the two limiting backing plates 10 at both ends to continuously approach, the lower end of the communication tower is limited, and further, the installation and adjustment process of the communication tower can be made simpler and more convenient.
