Description
Technical Field
[0001] This utility model relates to the field of filter accessories technology, specifically a novel filter base plate. Background Technology
[0002] A filter is a frequency-selective device that allows specific frequency components of a signal to pass through while greatly attenuating other frequency components. By utilizing this frequency-selective function of filters, interference noise can be filtered out or spectrum analysis can be performed. In other words, any device or system that allows specific frequency components of a signal to pass through while greatly attenuating or suppressing other frequency components is called a filter.
[0003] Currently, filters need to be used with a base plate to position the filter in the required location.

[0022] Embodiment 1:
[0023] Please refer to Figure 1-5 , a new type of filter bottom plate, including a placement plate 1. Both ends of the top of the placement plate 1 are slidably connected with stop plates 2.

A transmission component 8 is arranged between the two stability plates 7, and the transmission component 8 is used to drive the stability plate 7 to move vertically;
[0024] In this embodiment, a plurality of heat dissipation holes are provided at the top of the placement plate 1 for timely guiding out the heat generated during the operation of the filter;
[0025] In this embodiment, the placement plate 1 has a "U" - shaped structure, and through - holes are provided at the four corners of the placement plate 1. Due to the structural characteristics of the placement plate 1, space can be provided for the assembly of the central shaft rod 3;
[0026] In this embodiment, a stability slide rod is fixedly connected to the bottom end of the inner side of the placement plate 1, and both guiding plates 5 are slidably connected to the outside of the stability slide rod;
[0027] In this embodiment, linear sliding grooves are provided on both sides of the top of the placement plate 1. Both ends of the bottom of the stop plate 2 are fixedly connected with linear sliders, and the stop plate 2 is slidably connected to the inside of the linear sliding grooves through the linear sliders. By using the settings of the linear sliding grooves and the linear sliders, the displacement of the stop plate 2 can be effectively guided to avoid uncontrollable displacement of the stop plate 2, and both the linear sliding grooves and the linear sliders are of I - shaped structure;
[0028] In this embodiment, protective pads are fixedly connected to the ends of the two stop plates 2 that are close to each other and the bottom end of the stabilizing plate 7. The protective pads are provided with anti-slip texture. The protective pads can protect the filter and prevent the stop plates 2 and the stabilizing plate 7 from damaging the filter housing.
[0029] In this embodiment, a clearance groove is provided in the middle of the top of the placement plate 1, and the guide plate 5 is located inside the clearance groove.
[0030] Example 2:
[0031] Please see Figure 1-5 This embodiment provides a technical solution based on embodiment one: the transmission assembly 8 includes a linkage shaft 9, a linkage rotating shaft 10, a linkage spur gear 11, and an eccentric plate 12. The linkage shaft 9 is rotatably connected to the middle of the guide plate 5, and the linkage rotating shaft 10 is rotatably connected to the middle of the bottom end of the stop plate 2. The linkage shaft 9 and the linkage rotating shaft 10 are both fixedly connected to the outer sides of the linkage shaft 9 and the linkage spur gear 11, and the two linkage spur gears 11 are meshed. The eccentric plate 12 is fixedly connected to one end of the linkage rotating shaft 10, and the linkage plate 13 is rotatably connected to the end of the eccentric plate 12 away from the linkage rotating shaft 10. The mounting base 14 is fixedly connected to the middle of the bottom end of the stabilizing plate 7, and the end of the linkage plate 13 away from the eccentric plate 12 is also rotatably connected to the mounting base 14.
[0032] The transmission assembly 8 also includes a transmission shaft 15, a transmission worm gear 16, an extension seat 17, and a drive shaft 18. The transmission shaft 15 is rotatably connected to the inner side of the placement plate 1, and the two linkage shafts 9 are slidably connected to the outer side of the transmission shaft 15. One end of the transmission shaft 15 is fixedly connected to the transmission worm gear 16. The end of the placement plate 1 near the transmission worm gear 16 is fixedly connected to the extension seat 17. One end of the extension seat 17 is rotatably connected to the drive shaft 18. One end of the drive shaft 18 is fixedly connected to the transmission worm 19, and the transmission worm 19 is meshed with the transmission worm gear 16.
[0033] In this embodiment, the linkage rod 9 has a hollow structure. A limiting strip is fixedly connected to the outer side of the transmission shaft rod 15. A limiting groove is formed on the inner wall of the linkage rod 9, and the limiting strip is also slidably connected inside the limiting groove. By using the setting of the limiting strip and the limiting groove, the linkage rod 9 can slide along the transmission shaft rod 15. When the transmission shaft rod 15 rotates, since the limiting strip is still inside the limiting groove, the linkage rod 9 can be driven to rotate with the help of the limiting strip.
[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0035] Working principle: First, place the filter on the top of the placement plate 1, then rotate the central shaft 3. Since the threads of the two threaded sections 4 are opposite, when the central shaft 3 rotates, the connection between the threaded section 4 and the guide plate 5 can drive the two stop plates 2 to move closer to each other until the stop plates 2 contact the filter, thus positioning the filter between the two stop plates 2.
[0036] Subsequently, rotating the drive shaft 18 causes the transmission worm gear 19 to actuate the transmission worm wheel 16, thereby driving the transmission shaft 15 to rotate. With the connection between the transmission shaft 15 and the linkage shaft 9, the linkage shaft 9 can rotate with the transmission shaft 15. In conjunction with the connection between the two linkage spur gears 11, the power of the linkage shaft 9 can be transmitted to the linkage rotating shaft 10, thereby driving the eccentric plate 12 to rotate. Since the linkage plate 13 is connected between the eccentric plate 12 and the mounting base 14, when the eccentric plate 12 rotates, it can pull the stabilizing plate 7, causing the stabilizing plate 7 to move vertically under the limit of the limiting slide rod 6 until the stabilizing plate 7 contacts the top of the filter, thereby stabilizing and limiting the filter.
