Description

Technical Field

[0001] The utility model relates to the technical field of antenna design, in particular to a portable antenna protection switch. Background Art

[0002] Portable antennas are small in size and easy to carry and transport. Usually, in order to avoid the portable antenna being started to send and receive signals during transportation or before installation is completed, energy consumption is caused and the service life of the equipment is reduced.

[0003] Usually, an electronic switch is designed for a portable antenna. The portable antenna is turned on by operating the power button of the electronic switch and then put into operation. However, the electronic switch may be accidentally touched during transportation, and the reliability and cost of the electronic switch are inferior to those of the mechanical switch. Therefore, a mechanical switch is usually added to the portable antenna as a protection switch for the electronic switch.

[0004] For example, the Chinese utility model patent with announcement number CN216389697U discloses an antenna base with a radio frequency circuit protection function, so that when the antenna is not installed, the protection switch is in an open circuit state. At this time, even if the main switch of the radio frequency device is turned on, the radio frequency circuit will not work; when the antenna thread is screwed onto the base, the antenna pressure plate presses the protection switch downward until the circuit is closed, and the main switch can be turned on normally to start it.

[0005] Although the above scheme realizes the switch protection of the electronic switch by mechanical means, in actual use, on the one hand, the antenna is rotated and twisted to close the protection switch, which is cumbersome to operate, increases the difficulty of installation, and reduces the installation efficiency; on the other hand, the circuit is closed after the protection switch is squeezed downward, which leads to the problem of accidental triggering of the protection switch due to shaking during actual transportation and installation, and has low reliability and cannot meet actual protection needs. Utility Model Content

[0006] The utility model aims to provide a portable antenna protection switch to solve the problems of low reliability and complicated operation of the current portable antenna protection switch.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] refer to Figures 1 to 3 The present embodiment provides a portable antenna protection switch, including a sensing column 2 and a contact switch 1, wherein the sensing column 2 is used to adjust its up and down position, that is, to adjust the distance between the sensing column 2 and the contact switch 1, so as to start or close the contact switch 1. When the contact switch 1 is turned on, the portable antenna is powered on. At this time, the portable antenna can be used by turning on the start switch of the portable antenna. When the contact switch 1 is turned off, the portable antenna is in a power-off state. Even if the start switch of the portable antenna is turned on, the portable antenna will not work.

[0026] Among them, the sensing column 2 is located directly below the contact switch 1. The sensing column 2 is connected to the outside of the portable antenna through the lifting drive 3. The sensing column 2 is arranged on the outside of the portable antenna for easy operation. At the same time, the sensing column 2 is arranged below the contact switch 1 to avoid the sensing column 2 being squeezed downward and close to the contact switch 1 during installation or transportation, thereby preventing the portable antenna from being accidentally touched and started.

[0027] At the same time, by setting the lifting drive 3, the up and down movement of the sensing column 2 can be restricted. On the one hand, it can prevent the sensing column 2 from shaking close to the contact switch 1 during installation or transportation, thereby improving its reliability; on the other hand, the lifting drive 3 can assist the sensing column 2 in moving up and down to improve its operating efficiency and improve the installation efficiency of the portable antenna.

[0028] Specifically, the lifting drive 3 can be selected as a hydraulic lifting mechanism, a pneumatic lifting mechanism or an electronic lifting mechanism. The output end of the lifting drive 3 is connected to the sensing column 2 to facilitate driving the sensing column 2 to move up and down, thereby reducing the difficulty of manual operation and improving operation efficiency.

[0029] Preferably, the lifting drive 3 is selected as a spring, and the service life and reliability are improved through the mechanical structure.

[0030] At this time, the lifting drive 3 is set on the outside of the sensing column 2 and connected to the sensing column 2. When the sensing column 2 moves upward, it can increase the force applied when moving upward under the limitation of the spring, thereby preventing the sensing column 2 from shaking during installation, transportation or handling, thereby avoiding accidental activation of the portable antenna due to accidental touch, and ensuring reliability of use.

[0031] To further explain, in order to increase the service life and reduce the maintenance cost, it is preferred that a switch protection cover 4 is sleeved on the outer side of the contact switch 1 , and a sensing column base 5 is sleeved on the outer side of the sensing column 2 .

[0032] Specifically, the switch protection cover 4 is connected to the portable antenna, and the bottom end of the switch protection cover 4 extends downward to below the bottom end of the contact switch 1. The switch protection cover 4 is coaxially arranged with the sensing column 2. The inner diameter of the bottom of the switch protection cover 4 is larger than the outer diameter of the contact end of the contact switch 1. Correspondingly, the inner diameter of the bottom of the switch protection cover 4 is larger than the outer diameter of the sensing column 2, so that when the sensing column 2 moves upward, it passes through the bottom of the switch protection cover 4 and extends upward until it approaches or touches the contact switch 1 to realize the opening of the protection switch; the safety protection of the contact switch 1 is increased, the contact and collision with the outside world are reduced, the service life is increased, and the maintenance cost is reduced.

[0033] The induction column base 5 is also sleeved on the outside of the induction column 2 and connected to the portable antenna. The induction column base 5 is located below the switch protection cover 4 to protect the induction column 2 and increase its service life.

[0034] The sensing column base 5 is also sleeved on the outside of the lifting drive 3. When the lifting drive 3 is not a spring, the lifting drive 3 is arranged at the bottom of the sensing column base 5; when the lifting drive 3 is a spring, the lifting drive 3 can be selected to be arranged above the sensing column base 5, below the sensing column base 5, or extend from the top of the sensing column base 5 to the bottom of the sensing column base 5; at the same time, a limiting groove 6 is provided on the sensing column base 5, and a limiting member 7 is provided on the sensing column 2, so that the limiting member 7 can drive the sensing column 2 to move along the limiting groove 6.

[0035] For example, the bottom end of the lifting drive 3 is connected to the bottom end of the sensing column base 5, and the top end of the lifting drive 3 is connected to the sensing column 2, so that the lifting drive 3 needs to be stretched when the sensing column 2 moves upward to avoid accidental touching of the sensing column 2.

[0036] For example, the top end of the lifting drive 3 is connected to the top end of the sensing column base 5, and the bottom end of the lifting drive 3 is connected to the sensing column 2, so that the lifting drive 3 needs to be squeezed when the sensing column 2 moves upward to avoid accidental touching of the sensing column 2.

[0037] For example, the top end of the lifting drive 3 is connected to the top end of the sensing column base 5, and the bottom end of the lifting drive 3 is connected to the bottom end of the sensing column base 5. A clamping block is provided on the sensing column 2, and the lifting drive 3 is sleeved on the outside of the clamping block and connected to the sensing column 2 through the clamping block. Therefore, when the sensing column 2 moves upward, it is necessary to stretch the bottom spring and squeeze the top spring, thereby further improving the reliability of the protective switch.

[0038] To further illustrate, the lifting drive 3 may optionally include an upward pressure spring c and a downward pull spring d, both of which are sleeved on the outside of the sensing column 2, the upward pressure spring c is located above the clamping block and connected between the clamping block and the top of the sensing column base 5, and the downward pull spring d is located below the clamping block and connected between the clamping block and the bottom of the sensing column base 5, thereby facilitating the segmented maintenance and repair of the lifting drive 3.

[0039] Correspondingly, the limit groove 6 is opened on the outside of the lifting drive 3, one end of the limit member 7 is connected to the sensing column 2, and can be optionally connected to the clamping block, and the other end of the limit member 7 passes through the limit groove 6 and extends to the outside of the sensing column base 5, which is convenient for manual operation.

[0040] Specifically, the limit groove 6 requires both a moving channel when the limit member 7 drives the sensing column 2 to move upward, and a channel for clamping and limiting the limit member 7 after the upward movement is completed. Therefore, the limit groove 6 is selected to be an L-shaped structure. At this time, the limit groove 6 includes a vertically arranged guide groove a and a horizontally arranged clamping groove b. The clamping groove b is located at the top of the guide groove a. When the limit member 7 drives the sensing column 2 to move upward to one end of the clamping groove b along the guide groove a, it moves horizontally to the other end of the clamping groove b to limit the limit member 7 and prevent the limit member 7 from moving downward. It is further selected to open a groove at the other end of the clamping groove b for clamping the limit member 7 to prevent the limit member 7 from falling off from the clamping groove b.

[0041] When the protection switch is turned off, the limiting member 7 is laterally moved from the other end of the clamping groove b to the top of the guide groove a, and then the limiting member 7 is moved downward. At this time, the bottom of the sensing column 2 can selectively pass through the sensing column base 5 and extend to its outside, thereby reducing the volume of the sensing column base 5, reducing the weight and the occupied area.

[0042] The above is the embodiment of the present application. The above embodiments and the specific parameters in the embodiments are only for the purpose of clearly describing the verification process of the application, and are not intended to limit the scope of patent protection of the present application. The scope of patent protection of the present application is still subject to its claims, and any equivalent structural changes made by using the description and drawings of the present application should be included in the scope of protection of the present application.
