Description

Technical Field

[0001] The utility model belongs to the field of base station antenna auxiliary equipment and relates to a fastening and disassembly device for a base station plate antenna connector. Background Art

[0002] Base station antennas are an indispensable and key part of mobile communication systems to achieve wireless communication. The electrical performance parameters of base station antennas are one of the necessary conditions for screening the quality of antennas. The performance of most base station antennas is optimized through continuous debugging. Usually, when testing electrical performance parameters, test equipment is used to connect. One side of the double male feeder is connected to the test equipment, and the other side is connected to the base station antenna connector. Whether the feeder connector and the antenna connector are in full contact affects the accuracy of the electrical performance test.

[0003] Nowadays, as base station antennas become more and more complex, the number of antenna connectors on most base station antennas has also increased, resulting in the compression of the spacing between two adjacent antenna connectors. At present, when testing base station antennas, the antenna connector and the feeder connector are mostly tightened with an adjustable wrench. Due to limited space, the adjustable wrench cannot be tightened directly for a circle, and it needs to be tightened in small sections, which is time-consuming and inefficient. The disassembly should be consistent with the installation. At the same time, if the adjustable wrench is used multiple times when it is clamped, the flange of the feeder connector will be damaged.

[0004] Therefore, it is necessary to improve the prior art to overcome the defects in the prior art. Utility Model Content

[0005] The utility model aims to provide a fastening and disassembling device, which is used to replace an adjustable wrench to perform the tightening operation of a connector and a feeder connector, thereby improving the convenience of the tightening operation of the connector and the feeder connector.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] A fastening and disassembly device comprises a locking sleeve, wherein a locking hole is embedded in one side of the locking sleeve, a through hole is arranged on the other side of the locking sleeve, and the through hole is communicated with the locking hole; and a force-bearing arm protruding outward is arranged on the locking sleeve.

[0008] Furthermore, the load-bearing arm and the locking sleeve are integrally formed.

[0009] Furthermore, the locking hole and the through hole are centrally arranged on the locking sleeve.

[0010] Furthermore, the locking sleeve is made of copolymerized oxymethylene material; the load-bearing arm is made of copolymerized oxymethylene material.

[0011] Furthermore, the diameter of the via hole is smaller than the diameter of the locking hole.

[0012] Furthermore, the locking hole is a hexagonal structure, and the via hole is a circular structure.

[0013] Furthermore, there are two force-bearing arms, which are distributed on both sides of the locking sleeve in a wing-shaped structure.

[0014] The above technical solution has the following beneficial effects:

[0015] 1. The fastening and disassembly device is made of POM machining, which is low-cost, light and portable. It is easy to operate, fast and efficient during installation and disassembly, and improves the convenience of tightening the connector and feeder connector;

[0024] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] Example

[0026] See also Figure 3 As shown, a fastening and disassembly device 4 includes a locking sleeve 44, and a locking hole 41 is embedded in one side of the locking sleeve 44. The locking hole 41 is a hexagonal structure in the embodiment. A through hole 42 is provided on the opposite side of the locking sleeve 44, and the through hole 42 is a circular structure. The through hole 42 is connected to the locking hole 41, and both are centrally arranged on the locking sleeve 44, wherein the aperture of the through hole 42 is smaller than the aperture of the locking hole 41. The locking sleeve 44 is provided with a force-bearing arm 43 protruding outward, and there are two force-bearing arms 43, which are symmetrically distributed on both sides of the locking sleeve and distributed in a wing-shaped structure.

[0027] In this embodiment, the locking sleeve 44 and the force-bearing arm 43 are both made of copolymerized acetal material, and the POM machining process is adopted. The force-bearing arm 43 and the locking sleeve 44 are integrally formed to form an integral structure.

[0028] Combination Figure 1 , Figure 2 As shown, one side of the base station antenna 1 has several antenna connectors 2, and the distance between two adjacent antenna connectors 2 is small, which is not conducive to the operation of the existing adjustable wrench. In this embodiment, a fastening and disassembly device 4 is used to easily install the feeder antenna 3 on the base station antenna 1. Specifically:

[0029] The connection end of the feeder antenna 3 is a feeder connector 31, which is an outer hexagonal structure as a whole and can be just inserted into the locking hole 41; the aperture of the through hole 42 is larger than the outer diameter of the antenna connector 2, so that the through hole 42 can be set on the antenna connector 2. During operation, first align the installation end of the feeder antenna 3 with the corresponding antenna connector 2, and then insert the fastening and disassembly device 4 from one side of the feeder antenna 3, so that the feeder connector 31 falls into the locking hole 41, and then the on-site personnel manually push the force arm 43 to thread the feeder connector 31 on the antenna connector 2. During disassembly, the force arm 43 can be pushed in the reverse direction to separate the feeder connector 31 from the antenna connector 2, so as to achieve the purpose of removing the feeder antenna 3.

[0030] The locking hole 41 in this embodiment is not limited to a hexagonal structure, and can be changed according to the outer structure of the feeder connector 31 , so that the locking hole 41 can adapt to the feeder connector 31 .

[0031] The fastening and disassembly device 4 of the utility model adopts a new structural design, which is completely different from the original adjustable wrench. It has the characteristics of small size, light weight, and easy to carry. It is easy to operate during installation and disassembly, will not damage the flange of the feeder connector, has high speed and high efficiency, and improves the convenience of tightening operations on the connector and the feeder connector.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
