Technical Field
[0001] This utility model relates to the field of air volume controller technology, and in particular to an air volume controller with snap-fit installation. Background Technology
[0002] A controller is a master control device that controls the starting, speed regulation, braking, and reversing of a motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence. Among them, air volume controllers are commonly used in household fans and industrial fans. Most controllers are fixed with screws, which makes disassembly and repair very inconvenient when the controller malfunctions.
[0003] Existing air volume controllers have some shortcomings in installation. Most controllers are fixed with screws, which makes the disassembly process cumbersome and time-consuming when the controller needs to be repaired or replaced. This not only increases maintenance costs but may also affect the normal operation of the ventilation system, reducing the importance of installing the air volume controller. To address these issues, a snap-fit air volume controller is proposed for improvement and upgrade. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figure 1 - Figure 4 As shown in the figure, this embodiment provides a snap-fit air volume controller, including a mounting base 1, an air volume controller body 2 on the top of the mounting base 1, two guide base plates 4 fixedly mounted on the bottom of the air volume controller body 2, two positioning rods 5 symmetrically arranged between the two guide base plates 4, mounting grooves 6 are opened on both sides inside the mounting base 1, and mounting components 3 are arranged inside the mounting grooves 6. The mounting components 3 include a limiting frame 31, which is fixedly installed inside the mounting grooves 6. Two guide slides 325 are opened inside the limiting frame 31, and a first guide plate 32 and a second guide plate 33 are slidably connected inside the two guide slides 325 respectively. A first spring 324 and a second spring 332 are respectively arranged on the outer side of the first guide plate 32 and the second guide plate 33, and one end of the second guide plate 33 is set on the guide base plate 4.
[0024] Preferably, a first limiting plate 323 is fixedly provided on the outer wall of the first guide plate 32, and two first springs 324 are provided in total. One end of the first spring 324 is connected to the first limiting plate 323, and the other end of the first spring 324 is connected to the top of the limiting frame 31. A first snap-fit block 321 is fixedly connected to one end of the first guide plate 32. A positioning groove 322 is provided at the upper end of the second guide plate 33. The first snap-fit block 321 and the positioning groove 322 are matched in size. A second limiting plate 334 is fixedly connected to the bottom of the second guide plate 33, and two second springs 332 are provided in total. One end of the second spring 332 is connected to the second limiting plate 334, and the other end is connected to the inner side of the bottom of the limiting frame 31. A handle 34 is fixedly connected to one end of both the first guide plate 32 and the second guide plate 33.
[0025] By pulling the handle 34, the first limiting plate 323 on the first guide plate 32 is driven to squeeze the first spring 324, causing the first locking block 321 on the first guide plate 32 to be misaligned from the positioning groove 322 on the second guide plate 33, thus separating the two guide plates. At the same time, pulling the second guide plate 33 causes the second limiting plate 334 to squeeze the second spring 332 inside the limiting frame 31, causing the second locking block 331 to be misaligned from the locking groove 41 on the guide base plate 4. Then, the operator can quickly pull the air volume controller out of the upper limit groove 42 of the mounting base 1 using the guide base plate 4, which facilitates the limiting and fixing of the bottom of the air volume controller and facilitates its installation. The second locking block 331 is compatible with the size of the locking groove 41.
[0026] Preferably, both guide base plates 4 have snap-fit grooves 41 inside. One end of the second guide plate 33 is fixedly connected to a second snap-fit block 331. One end of the second snap-fit block 331 passes through the interior of the mounting base 1 and its extended end is connected to the interior of the snap-fit groove 41. The upper surface of the mounting base 1 has two sets of limiting grooves 42 and four positioning holes 51 respectively. The guide base plate 4 and the positioning rod 5 are snapped into the limiting grooves 42 and the positioning holes 51 respectively.
[0027] By engaging the two guide plates 4 at the bottom of the air volume controller onto the two limit slots 42 on the mounting base 1, and simultaneously engaging the four positioning rods 5 at the bottom of the air volume controller onto the positioning holes 51, it is easy to accurately engage and position the air volume controller.
[0028] The working principle and operation process of this utility model are as follows: When it is necessary to disassemble and replace the air volume controller, the operator first pulls the handle 34 to drive the first limiting plate 323 on the first guide plate 32 to squeeze the first spring 324, causing the first locking block 321 on the first guide plate 32 to be displaced from the positioning groove 322 on the second guide plate 33, thus separating the two guide plates. At the same time, pulling the second guide plate 33 drives the second limiting plate 334 to squeeze the second spring 332 inside the limiting frame 31, causing the second locking block 331 to be displaced from the locking groove 41 on the guide base plate 4. Open, and then the staff quickly pulls the air volume controller out of the upper limit groove 42 of the mounting base 1 using the guide base plate 4, which is convenient for disassembling and replacing the air volume controller. When installation is required, the operator engages the two guide base plates 4 at the bottom of the air volume controller with the two limit grooves 42 on the mounting base 1. At the same time, the four positioning rods 5 at the bottom of the air volume controller are precisely engaged with the positioning holes 51. The principle is the same as above. The two second locking blocks 331 are moved to fix the guide base plates 4, which is convenient for the stable installation of the air volume controller and avoids problems such as difficulty in disassembly and assembly caused by fixing with bolts.
