Description

Technical Field

[0001] The utility model belongs to the technical field of pre-selectors and post-selectors, and more specifically, relates to an anti-interference pre-selector and post-selector. Background Art

[0002] A pre-postselector is a frequency-automatic tracking bandpass filter connected to the transmitter and receiver system channels. It can change the filter center frequency within 2 to 30 MHz for filtering to improve the system's anti-interference performance and reduce interference to other devices. Pre-postselectors are divided into two categories according to their structure: cavity pre-postselectors and LC pre-postselectors. Pre-postselectors have the characteristics of good selectivity, low noise figure, high speed, and low power consumption. Pre-postselectors are mainly used in various types of airborne, vehicle-mounted, and ship-mounted FM radio stations.

[0003] Based on the above, the inventors have discovered the following problems: the current pre-selector needs to be connected to a wire when in use, and the installation position of the pre-selector in the device is fixed. At the same time, the pre-selector needs to be connected to a wire, so when the pre-selector is connected, the wire and the interface of the pre-selector may not be on the same line, so the wire will bend and connect to the pre-selector. The bent wire may cause the circuit layout within the setting to be messy, and may also shorten the life of the wire.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an interference-resistant preselector is provided to achieve a purpose with greater practical value. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides an anti-interference pre-selector to solve the problem that the orientation of the interface of the current pre-selector is difficult to adjust during installation.

[0006] The purpose and effect of the anti-interference preselector of the present invention are achieved by the following specific technical means:

[0007] An interference-resistant pre-selector includes a pre-selector body, a mounting component installed at the bottom of the pre-selector body, a first bolt installed on the surface of the mounting component, a threaded hole opened at the bottom of the pre-selector body, the first bolt passes through the mounting component and extends into the threaded hole, and a mechanism for fixing the pre-selector body is installed on the top of the mounting component.

[0008] Furthermore, the mechanism for fixing the pre-selector body includes connecting blocks installed on both sides of the pre-selector body, and also includes a circular groove opened on the surface of the mounting component, and a second bolt is installed through the surface of the connecting block.

[0009] Furthermore, the mounting component includes a mounting plate and connecting plates mounted on both sides of the mounting plate, and mounting holes are provided on surfaces of the connecting plates.

[0010] Furthermore, rubber pads are installed at the ends of the first bolt and the second bolt.

[0011] Furthermore, the mounting component is made of metal.

[0012] Furthermore, the mounting component is made of plastic.

[0013] Furthermore, the material of the installation component is flame retardant plastic.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model cooperates with the mounting component, the first bolt and the threaded hole. When in use, the pre-selector body is first placed on the mounting component, and then the first bolt is screwed into the threaded hole through the mounting component, and then the pre-selector body is rotated to a suitable position, and then the pre-selector body is fixed. Through the above design, the position of the pre-selector body can be effectively adjusted, and the path of the wire and the interface of the pre-selector body can be made consistent, thereby avoiding the bending of the wire.

[0016] Through the coordinated use of the connecting block, the circular groove and the second bolt, when in use, the rotation of the pre-selector body will drive the rotation of the connecting block, and the rotation of the connecting block will drive the second bolt to rotate in the circular groove. When the pre-selector body is rotated to a suitable position, only the second bolt needs to be rotated. When the second bolt contacts the surface of the circular groove, it will drive the pre-selector body to rise, thereby driving the first bolt to rise. The friction between the first bolt and the pre-selector body can fix the pre-selector body. Through the above design, the pre-selector body can be effectively fixed.

[0029] As attached Figure 1 To the attached Figure 3 As shown:

[0030] The utility model provides an interference-resistant pre-selector, comprising a pre-selector body 1, a mounting component 2 being installed at the bottom of the pre-selector body 1, a first bolt 3 being installed on the surface of the mounting component 2, a threaded hole 4 being opened at the bottom of the pre-selector body 1, the first bolt 3 passing through the mounting component 2 and extending into the threaded hole 4, and a mechanism 5 for fixing the pre-selector body being installed at the top of the mounting component 2.

[0031] By using the mounting component 2, the first bolt 3 and the threaded hole 4 in combination, when in use, first place the pre-selector body 1 on the mounting component 2, and then pass the first bolt 3 through the mounting component 2 and screw it into the threaded hole 4. It should be noted that when the first bolt 3 is fully screwed into the pre-selector body 1, there is still a gap between the first bolt 3 and the mounting component 2, so the pre-selector body 1 can be rotated to a suitable position, and then the pre-selector body 1 can be fixed. Through the above design, the position of the pre-selector body 1 can be effectively adjusted, and the path of the wire and the interface of the pre-selector body 1 can be made consistent, thereby avoiding bending of the wire.

[0032] The mechanism 5 for fixing the pre-selector body includes connecting blocks 501 installed on both sides of the pre-selector body 1 and a circular groove 502 opened on the surface of the mounting component 2. A second bolt 503 is installed through the surface of the connecting block 501.

[0033] Through the coordinated use of the connecting block 501, the circular groove 502 and the second bolt 503, when in use, the rotation of the pre-selector body 1 will drive the connecting block 501 to rotate, and the rotation of the connecting block 501 will drive the second bolt 503 to rotate in the circular groove 502. When the pre-selector body 1 is rotated to a suitable position, it is only necessary to rotate the second bolt 503. When the second bolt 503 contacts the surface of the circular groove 502, it will drive the pre-selector body 1 to rise, thereby driving the first bolt 3 to rise. The friction between the first bolt 3 and the pre-selector body 1 can fix the pre-selector body 1. Through the above design, the pre-selector body 1 can be effectively fixed.

[0034] The mounting component 2 includes a mounting plate 201 and connecting plates 202 mounted on both sides of the mounting plate 201 . Mounting holes 203 are formed on the surface of the connecting plates 202 .

[0035] By using the mounting plate 201 , the connecting plate 202 and the mounting hole 203 , the mounting component 2 can be easily installed.

[0036] Wherein, rubber pads 6 are installed at the ends of the first bolt 3 and the second bolt 503 .

[0037] By using the rubber pad 6 , the friction force can be increased and damage to the mounting component 2 can be avoided.

[0038] Wherein, the material of the installation component 2 is metal.

[0039] By using a metal material, the strength of the mounting component 2 can be increased.

[0040] Wherein, the material of the installation component 2 is plastic.

[0041] By using plastic material, the cost of the mounting component 2 can be reduced.

[0042] The material of the installation component 2 is flame-retardant plastic.

[0043] By using flame-retardant plastic, the flame retardancy of the mounting component 2 can be improved.

[0044] The specific usage and function of this embodiment are as follows:

[0045] When the present invention is used, the pre-selector body 1 is first placed on the mounting component 2, and then the first bolt 3 is passed through the mounting component 2 and screwed into the threaded hole 4. It should be noted that when the first bolt 3 is fully screwed into the pre-selector body 1, there is still a gap between the first bolt 3 and the mounting component 2. Then the mounting component 2 is installed in a suitable position through the mounting hole 203, and then the pre-selector body 1 can be rotated to a suitable position, and then the second bolt 503 is rotated. When the second bolt 503 contacts the surface of the circular groove 502, it will drive the pre-selector body 1 to rise, thereby driving the first bolt 3 to rise. The friction between the first bolt 3 and the pre-selector body 1 can fix the pre-selector body 1. Through the above design, the pre-selector body 1 can be effectively fixed, and then the wire is connected to the interface of the pre-selector. Through the above design, the position of the pre-selector body 1 can be effectively adjusted, and the path of the wire and the interface of the pre-selector body 1 can be made consistent, thereby avoiding bending of the wire.
