Description

Technical Field

[0001] The utility model relates to the technical field of feeder installation devices, in particular to a latch-type base adapter. Background Art

[0002] Cable is a general term for optical cables, electrical cables, etc. Cables have many uses, mainly used for controlling installation, connecting equipment, transmitting electricity, etc. They are common and indispensable in daily life. When laying cables, cables often cross, which not only affects the appearance, but also may generate eddy currents and cause certain losses. At this time, cable fixing clamps are needed to organize and fix the cables to prevent them from moving due to external force or weight.

[0003] The Chinese utility model with publication number CN113612169B provides a low intermodulation cable clamp, which includes a plastic clamp body, a cavity for clamping cables, and a first connection component and a second connection component are respectively arranged on both sides of the plastic clamp body. The first connection component and the second connection component are connected to each other to achieve the connection between the two plastic clamp bodies. This matching method can achieve the connection between multiple cable clamps, which increases the number of cables to be clamped, thereby achieving the clamping of multiple cables.

[0004] During the installation of the low intermodulation cable clamp on the pole, the installation in different directions is realized by using the installation bracket. The Chinese utility model with publication number CN211320803U provides a three-directional feeder installation bracket, which uses a first installation plate, a second installation plate, and a third installation plate to form the entire installation bracket, thereby forming three groups of installation holes in different directions. When installing the low intermodulation cable clamp, any group of installation holes can be selected for installation to realize the installation of the low intermodulation cable clamp in different directions.

[0005] The above-mentioned low intermodulation cable clamp is connected to the above-mentioned three-way feeder mounting bracket by using a cable tie. This connection method using a cable tie has, on the one hand, low strength of the cable tie and is easy to break; on the other hand, the cable tie is usually used once. When disassembling the low intermodulation cable clamp, the cable tie needs to be cut off and cannot be reused.

[0006] Therefore, the utility model proposes a latch-type base adapter to solve the above problem. Utility Model Content

[0020] The latch pin slot of the utility model is opened along the radial direction of the transfer shaft, which is convenient for aligning and plugging the latch pin. The cross section of the latch pin slot is square-shaped, and the latch pin is limited after being inserted into the latch pin channel, so as to avoid relative rotation of the latch pin in the latch pin slot, thereby causing unnecessary wear and tear, thereby extending the service life of the latch pin.

[0021] The utility model arranges two elastic cards at the end of the latch body, and the middle part of the elastic card is bent outward to form a bent part. The elastic deformation ability of the elastic card is utilized to facilitate the insertion and removal of the latch, and the latch can be limited after the latch is inserted into the latch slot.

[0022] In the utility model, the end face of the plug-in expansion section close to the plug-in section is an arc-shaped curved surface matching the outer wall of the adapter shaft. After the plug-in section is inserted into the latch slot, the end face of the plug-in expansion section fits with the outer wall of the adapter shaft, making the connection structure more stable.

[0023] The utility model provides a push plate on the bolt body, which makes it convenient for operators to apply force to insert or remove the bolt. BRIEF DESCRIPTION OF THE DRAWINGS
