Description

A height-adjustable support device for inverter mounting base Technical Field

[0001] This utility model relates to the field of inverter base technology, and in particular to an inverter mounting base height adjustment support device. Background Technology

[0002] The inverter base is a key connecting component between the inverter and the installation environment. The base is usually designed with standardized mounting holes, which can be used to fix the inverter to the cabinet, wall or ground with bolts, screws and other fasteners. This ensures that the equipment remains stable under vibration, impact and other conditions, and avoids problems such as cable pulling and loosening of interfaces caused by displacement.

[0003] Currently, the existing inverter mounting bases have a relatively simple structure. After installation, the bottom wall of the mounting base is usually directly attached to the ground or the bottom plate of the cabinet. Since the inverter generates a lot of heat during operation, the base being in close contact with the mounting surface makes it difficult for air to circulate effectively, which causes heat to accumulate around the inverter. This affects the inverter's heat dissipation and may lead to overload protection or component aging due to excessive temperature. To address this issue, we propose an inverter mounting base height adjustment support device. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a height-adjustable support device for inverter mounting bases.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A height-adjustable support device for a frequency converter mounting base includes a base body. The base body has two sets of storage slots inside, and a support plate is inserted into each of the two sets of storage slots. Mounting blocks are fixedly connected to the front and rear ends of each support plate. Connecting strips are distributed along the sides of the base body, and a first slider is fixedly connected to the inner side of each connecting strip. A sliding groove adapted to the first slider is formed at the top of the base body. A spring is laterally connected to the side wall of the sliding groove, and the other end of the spring is fixedly connected to the side of the first slider. A limiting block is fixedly connected to the inner side of each connecting strip. The side of the limiting block extends through the inner wall of the base body into the support plate. Two limiting grooves adapted to the limiting blocks are formed at the upper and lower ends of the support plate. A rectangular groove is formed inside the base body, and a perforated plate is provided inside the rectangular groove.

[0007] Preferably, the side of the perforated plate is connected to a locking block, and the inner wall of the rectangular groove is provided with an insertion slot that matches the locking block.

[0008] Preferably, a pull block is fixedly connected to the front side of the perforated plate, and a rubber sleeve is glued to the outer wall of the pull block.

[0009] Preferably, a second slider is fixedly connected to the top of the support plate, and a slide rail adapted to the second slider is provided inside the base body.

[0010] Preferably, two sets of connecting rods are symmetrically distributed on the upper side of the base body, and the ends of the connecting rods are fixedly connected to the connecting strip.

[0011] Preferably, the card blocks are provided in two sets, and the two sets of card blocks are configured as T-shaped structures.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This device is equipped with a support plate and a storage slot. During use, the height of the base body can be adjusted by the cooperation of the storage slot and the support plate to form an air convection channel, accelerate the dissipation of heat to the outside, and prevent overload protection or device aging caused by excessive temperature.

[0014] 2. This device features a perforated plate and locking blocks. During use, the perforated plate increases the support area for the frequency converter, effectively dispersing the downward force on the frequency converter, reducing local stress concentration, lowering the risk of base deformation and damage, and extending its service life. The locking blocks also allow workers to quickly remove the perforated plate for cleaning and maintenance. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Referring to Figures 1-4, a variable frequency drive (VFD) mounting base height adjustment support device includes a base body 1. The base body 1 has two sets of storage slots 2 inside, and a support plate 3 is inserted into each of the two sets of storage slots 2. Mounting blocks 4 are fixedly connected to the front and rear ends of the support plates 3, respectively. Connecting strips 5 are distributed along the sides of the base body 1, and a first slider 6 is fixedly connected to the inner side of the connecting strips 5. A sliding groove 10 adapted to the first slider 6 is formed on the top of the base body 1. A spring 7 is horizontally connected to the side wall of the sliding groove 10, and the other end of the spring 7 is fixedly connected to the side of the first slider 6. A limit block 8 is fixedly connected to the inner side of the connecting strips 5. The side of the positioning block 8 extends through the inner wall of the base body 1 into the support plate 3. The upper and lower ends of the support plate 3 are provided with two sets of limiting grooves that are adapted to the positioning block 8. The interior of the base body 1 is provided with a rectangular groove, and the interior of the rectangular groove is provided with a perforated plate 11. When using this device, by adjusting the height of the base body 1, its bottom wall can be effectively prevented from being tightly attached to the mounting surface. With the perforated plate 11 provided inside the rectangular groove, an airflow channel can be provided to improve the heat dissipation effect of this device. After use, the support plate 3 can be embedded into the storage slot 2 to reduce the floor space occupied by this device, thereby reducing the cost of transportation and packaging.

[0022] Furthermore, referring to Figures 2 and 4, it can be seen that the side of the perforated plate 11 is connected to a locking block 12, and the inner wall of the rectangular groove is provided with an insertion slot that matches the locking block 12. During use, the perforated plate 11 can effectively disperse the downward force of the frequency converter, thereby reducing local stress concentration and lowering the risk of base deformation and damage. Through the cooperation of the locking block 12 and the insertion slot, it is convenient for the staff to quickly pull the perforated plate 11 out from the inside of the base body 1 for maintenance and cleaning, so as to effectively prevent the holes inside the perforated plate 11 from being blocked and affecting heat dissipation.

[0023] Furthermore, referring to Figure 4, it can be seen that a pull block 13 is fixedly connected to the front side of the perforated plate 11, and a rubber sleeve is glued to the outer wall of the pull block 13. In use, the pull block 13 and the rubber sleeve make it easy for workers to quickly pull out the perforated plate 11, thereby effectively improving the convenience of the perforated plate 11 during disassembly and assembly.

[0024] Furthermore, referring to Figures 3 and 4, it can be seen that the top of the support plate 3 is fixedly connected to the second slider 9, and the interior of the base body 1 is provided with a slide rail that is compatible with the second slider 9. Through the cooperation of the second slider 9 and the slide rail, the support plate 3 can be vertically guided and the support plate 3 can be limited, thereby effectively preventing the support plate 3 from being completely pulled out of the storage slot 2.

[0025] Furthermore, referring to Figure 2, it can be seen that two sets of connecting rods 14 are symmetrically distributed on the upper side of the base body 1, and the ends of the connecting rods 14 are fixedly connected to the connecting strips 5. Through the setting of each set of connecting rods 14, the front and rear sets of connecting strips 5 set on one side of the base body 1 can be connected. Therefore, when the staff pulls the connecting rod 14, the two sets of connecting strips 5 connected to it can be driven to bear force at the same time. Through the connection of the connecting rods 14, the convenience of adjusting the height of the base body 1 can be improved.

[0026] Furthermore, referring to Figure 4, it can be seen that there are two sets of locking blocks 12, and the two sets of locking blocks 12 are set as T-shaped structures. Through the two sets of T-shaped locking blocks 12, the tightness and reliability of the perforated plate 11 being inserted into the rectangular groove of the base body 1 can be effectively guaranteed.

[0027] Working Principle: In use, the operator first pulls the two sets of connecting rods 14 away from each other, thereby causing the connecting strip 5 connected to the connecting rods 14 to be simultaneously stressed. This pulls the limiting block 8 connected to the inner side of the connecting strip 5 out of the support plate 3. Then, the support plate 3 inserted inside the storage groove 2 moves downward under gravity and slides along the inner wall of the storage groove 2. When the limiting groove at the bottom of the support plate 3 corresponds to the limiting block 8, the limiting block 8 is re-embedded into the support plate 3 by the elastic force of the spring 7, thus limiting the support plate 3 and enabling the lifting operation of this device.

[0028] Then, the operator can connect the inverter to the base body 1 by welding or bolts. Then, the operator can place the four sets of mounting blocks 4 at the bottom of the base body 1 in the installation area and use bolts, screws and other fasteners to fix the inverter to the cabinet, wall or ground. The above is the complete working principle of this utility model.

[0029] In this utility model, the installation, connection or setting methods of all the components mentioned above are common mechanical methods, and the specific structure, model and coefficient index of all the components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
