Description

Technical Field

[0001] The utility model belongs to the technical field of fan frequency converters, and in particular relates to a fan frequency converter which is easy to assemble. Background Art

[0002] The fan inverter is a power regulating device that changes the motor speed by adjusting the frequency of the AC power supply, thereby controlling the output air volume and pressure of the fan. It is a special inverter tailored for various types of fans. It adopts a variable frequency speed control device to change the fan speed and thus the fan air volume to meet the needs of the production process. It also saves the most energy and has the highest comprehensive benefits.

[0003] At present, there are some inconveniences when assembling the inverter housing. The conventional fixing method requires the use of multiple screws for fixing, which can easily cause the screws to loosen or strip after long-term use; in addition, additional tools are required for installation and removal, which increases the difficulty and time cost of operation; this situation undoubtedly adds unnecessary trouble and cost to the fan inverter that needs frequent maintenance and overhaul. Utility Model Content

[0004] The purpose of the present invention is to provide a fan inverter that is easy to assemble, which can avoid the cumbersome steps of traditional bolt fixing and can achieve stable installation and fixation using only a few clips, making the assembly and disassembly process more time-saving and labor-saving, significantly reducing labor intensity and improving assembly efficiency.

[0005] The technical solutions adopted in this utility are as follows:

[0006] The lockhole that is formed on the upper and lower surfaces of the second end of the second end of the second end is formed, and the lockhole that is formed on the upper and lower surfaces of the second end of the second end of the second end is formed.

[0007] Furthermore, a first magnet is fixed to the top of one side of the pressing rod, and a second magnet that is magnetically attracted to the first magnet is provided on the inner wall of the L-shaped mounting groove.

[0008] Furthermore, rubber rings that are in frictional contact with the inner wall of the L-shaped installation groove are provided on both sides of the pressing rod.

[0009] The technical effects achieved by the fan are:

[0010] The two L-shaped clamping rods can be independently connected to the panel and the shell by buckling. When the panel and the shell need to be separated, the pressing rods need to be pressed at the same time, which improves the stability of the connection between the panel and the shell and can avoid the cumbersome steps of traditional bolt fixing, making the assembly and disassembly process more time-saving and labor-saving, and improving the assembly efficiency, and facilitating subsequent repair and maintenance. In addition, the pressing rod can be stored in the L-shaped installation groove, which can effectively avoid accidentally touching the pressing rod, thereby preventing the clamping head from being accidentally separated from the slot, thereby ensuring the stability of the equipment.

[0016] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0017] like Figure 1-3As shown, a fan inverter that is easy to assemble includes a shell 1, a panel 2 is rotatably installed on one side of the shell 1 through a hinge, and the shell 1 is rotatably connected to one side of the panel 2, which facilitates the assembly of the shell 1 and the panel 2. One side of the shell 1 is provided with two mutually symmetrical first L-shaped grooves 4, and an L-shaped clamping rod 5 is slidably installed inside the first L-shaped groove 4 up and down. The L-shaped clamping rod 5 consists of a vertical rod and a horizontal rod. One end of the horizontal rod passes through the outside of the first L-shaped groove 4 and is provided with a clamping head. The outer wall of the panel 2 is provided with two clamping grooves 1 matching the clamping head. 1. The combination of the card slot 11 and the card head can stably fix the shell 1 and the panel 2, eliminating the trouble of bolt fixing. The two sets of symmetrical card slots 11 and the card head can improve the stability and firmness of the fixing of the shell 1 and the panel 2. A first slide groove 7 connected to the first L-shaped groove 4 is opened on one side of the shell 1. A slider 8 fixed to the vertical rod is slidably installed inside the first slide groove 7. An L-shaped installation groove 9 is opened on one side of the slider 8. A rotating shaft is fixed at the inner corner of the L-shaped installation groove 9. A pressing rod is rotatably installed on the outer wall of the rotating shaft 10, the bottom end of the pressing rod 10 extends to the bottom of the slider 8, which is convenient for the two pressing rods 10 to drive the two sliders 8 to move, and the slider 8 drives the clamping head of the L-shaped clamping rod 5 to move, which is convenient for the separation of the clamping head and the clamping slot 11. The bottom end of the vertical rod is fixed with a first spring 6, and the bottom end of the first spring 6 is fixed to the inner wall of the first L-shaped groove 4, which is convenient for the first spring 6 to drive the L-shaped clamping rod 5 to move, so that the clamping head and the clamping slot 11 are buckled. It is more practical, simple in structure, easy to operate, and can facilitate the rapid assembly of the shell 1 and the panel 2. After installation, it is also relatively stable; a first magnet is fixed to the top of one side of the pressing rod 10, and a second magnet that is magnetically attracted to the first magnet is arranged on the inner wall of the L-shaped installation groove 9. When the pressing rod 10 is not in use, the pressing rod 10 can be stably fixed in the vertical groove of the L-shaped installation groove 9, thereby avoiding accidentally hitting the pressing rod 10; a second spring 12 is fixed to the bottom wall of the cross bar, and the bottom end of the second spring 12 is fixed to the inner wall of the first L-shaped groove 4, which can effectively prevent the L-shaped clamping rod 5 from being stuck by the first L-shaped groove 4 when it is reset, which is more practical;

[0018] like Figure 1 As shown, the inner side of the housing 1 is fixed with a circuit board 3 by butterfly bolts, making the whole relatively complete. By fixing with butterfly bolts, the circuit board 3 can be manually installed and removed conveniently.

[0019] Both sides of the pressing rod 10 are provided with rubber rings in frictional contact with the inner wall of the L-shaped mounting groove 9, which increase the friction force of the pressing rod 10 when rotating. When the pressing rod 10 is rotated, the pressing rod 10 can be stopped at any position, avoiding the bottom of the pressing rod 10 being unable to rotate to the desired position due to gravity, which is more practical;

[0020] like Figure 1 As shown, a heat dissipation hole is provided through one side of the housing 1 , and a heat dissipation fan is provided on the inner side of the housing 1 corresponding to the heat dissipation hole, so as to dissipate heat from the circuit board 3 inside the housing 1 .

[0021] The working principle of the utility model is as follows: during use, one side of the panel 2 is rotatably connected to the shell 1 by a hinge, the circuit board 3 is fixed in the shell 1 by a butterfly nut, and then the panel 2 is closed, and the card is inserted into the card slot 11 by the elastic force of the first spring 6, so that the shell 1 and the panel 2 are quickly assembled. When the shell 1 and the panel 2 are disassembled, first use the finger to press the bottom end of the pressing rod 10 so that the top end of the pressing rod 10 is rotated out of the L-shaped mounting groove 9, and then the two pressing rods 10 are rotated to a horizontal state so that one end of the pressing rod 10 is against the horizontal groove of the L-shaped mounting groove 9, and then the two pressing rods 10 are pressed at the same time with the fingers, and the two pressing rods 10 drive the slider 8 to move closer to each other, and the slider 8 drives the L-shaped card rod 5 to move, and the L-shaped card rod 5 drives the card head to separate from the card slot 11, so that the panel 2 can be opened conveniently.

[0022] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
