Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically to a fan housing. Background Technology

[0002] A fan is a common piece of equipment. A fan's structure generally includes a casing and an impeller housed within the casing. The impeller is connected to an external power shaft, which drives the impeller to rotate. Publication number CN217761460U discloses a fan casing that is easy to disassemble and assemble. It includes a first casing and a second casing, both of which are flexible. A cavity is formed between the first and second casings, and the first and second casings are detachably connected. One end of the first casing and one end of the second casing are fixed by a fastener. The other end of the first casing has a socket, and the other end of the second casing has a corresponding insertion block that is inserted into the socket. This application provides the advantage of facilitating the disassembly and installation of the fan casing.

[0003] However, in actual use, due to the large vibrations generated during the operation of the fan, in order to maintain the firmness of the connection between the two sets of housings, the fastening block needs to be tightly inserted into the connecting block. At this time, the connecting part needs to maintain a large rigidity to ensure stable connection strength. During disassembly, the protrusion needs to be pressed down. Due to the small size of the protrusion and the low elasticity of the connecting part, it is not easy to separate the fastening block from the inside of the connecting block, thus making it difficult to disassemble the housing. The disassembly is not convenient, and the connecting part and the protrusion are very easy to break during the disassembly process, which will make the equipment unable to be installed.

[0004] Therefore, it is necessary to invent a fan casing to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a fan housing to solve the problems in the technology of inconvenience in disassembling the housing, low ease of disassembly, and easy breakage of the connecting parts during disassembly, which leads to the inability to install the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fan housing, comprising a device housing, wherein device side plates are provided on both the left and right sides of the device housing, and a connecting assembly is provided between the device housing and the device side plates. The connecting assembly includes a locking block, a positioning groove, a plug-in groove, a limiting groove, an adjusting groove, a positioning block, a limiting block, an adjusting block, a support spring, a plug-in block, and a locking hole. Multiple sets of mounting grooves are provided on both the left and right edges of the device housing, and locking blocks are fixedly connected inside the multiple sets of mounting grooves.

[0007] By adopting the above technical solution, the plug block is inserted into the plug slot. At this time, the positioning block will be locked inside the locking hole to fix the plug block, thereby fixing the equipment side plate to the left and right sides of the equipment housing. Conversely, when disassembly is required, the adjusting block is moved to separate the positioning block from the locking hole, which can unlock the plug block and then disassemble the equipment side plate, effectively improving the convenience of disassembling the equipment side plate.

[0008] Optionally, the positioning groove is formed inside the locking block, the insertion groove is formed on the surface of the locking block, and the rear end of the positioning groove communicates with the insertion groove.

[0009] Optionally, the positioning block is slidably connected to the inside of the positioning groove, the rear end of the positioning block is arc-shaped, the support spring is disposed inside the positioning groove, and the two ends of the support spring abut against the side wall of the positioning groove and the end of the positioning block, respectively.

[0010] By adopting the above technical solution, the positioning block slides inside the positioning groove, and the support spring is used to push the positioning block to the rear side, so that the rear end of the positioning block is locked inside the insertion groove.

[0011] Optionally, the adjusting groove is formed on the upper surface of the locking block, and the limiting groove is formed between the adjusting groove and the positioning groove.

[0012] Optionally, the limiting block is slidably connected to the limiting groove, the adjusting block is slidably connected to the adjusting groove, and the upper and lower ends of the limiting block are fixedly connected to the adjusting block and the positioning block, respectively.

[0014] Optionally, multiple sets of plug-in blocks are fixedly connected to the side of the equipment side plate. The end of each plug-in block facing away from the equipment side plate is inclined, and locking holes are provided on the surface of each set of plug-in blocks.

[0015] By adopting the above technical solution, since the end of the plug block is inclined and the end of the positioning block is arc-shaped, the positioning block will be automatically pushed forward during the process of the plug block being inserted into the plug slot. When the locking hole moves to the rear end of the positioning block, the support spring will push the positioning block backward and lock it into the interior of the locking hole, thus automatically locking the plug block.

[0016] Optionally, the lower end of the device housing is fixedly connected to two sets of first fixing plates, and the surface of the first fixing plates is provided with first connecting holes.

[0017] Optionally, a second fixing plate is fixedly connected to the lower end of the side plate of the equipment, and overlapping plates are fixedly connected to both the front and rear ends of the second fixing plate. The surfaces of the second fixing plate and the overlapping plates are provided with second connection holes.

[0018] By adopting the above technical solution, after the equipment side plate and the equipment housing are spliced ​​together, the overlapping plate will be stuck on the upper side of the first fixing plate, and the second connecting hole on the surface of the overlapping plate will coincide with the first connecting hole on the surface of the first fixing plate. During the process of fixing the equipment, the screw will pass through the second connecting hole and the first connecting hole, further improving the stability of the connection between the equipment side plate and the equipment housing.

[0019] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention involves inserting a plug block into a plug slot, at which point a positioning block locks the plug block inside a locking hole, thus securing the equipment side panel to the left and right sides of the equipment housing. Conversely, when disassembly is required, the adjusting block is moved to separate the positioning block from the locking hole, unlocking the plug block and allowing the equipment side panel to be disassembled. This effectively improves the ease of disassembling the equipment side panel, effectively prevents damage to the connectors, and extends the service life of the equipment.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figures 1 to 5 The fan housing shown includes a housing 1, with side plates 3 on both the left and right sides of the housing 1. A connecting assembly is provided between the housing 1 and the side plates 3. The connecting assembly includes a locking block 2, a positioning groove 21, a plug-in groove 22, a limiting groove 23, an adjusting groove 24, a positioning block 25, a limiting block 26, an adjusting block 27, a support spring 28, a plug-in block 34, and a locking hole 35. Multiple sets of mounting grooves 11 are provided on the left and right edges of the housing 1. Locking blocks 2 are fixedly connected inside the multiple sets of mounting grooves 11. Multiple sets of plug-in blocks 34 are fixedly connected to the side of the side plates 3. The end of the plug-in block 34 facing away from the side plate 3 is inclined. Locking holes 35 are provided on the surface of the multiple sets of plug-in blocks 34.

[0024] The locking block 2 is welded inside the mounting groove 11. During the installation of the equipment side plate 3, the equipment side plate 3 is placed on the side of the equipment housing 1, and the plug block 34 is placed on the side of the locking block 2. At this time, the plug block 34 is directly inserted into the plug groove 22. The positioning block 25 will be stuck inside the locking hole 35, fixing the plug block 34 inside the plug groove 22, thereby fixing the equipment side plate 3 to the side of the equipment housing 1. During the disassembly of the equipment side plate 3, the positioning block 25 can be separated from the locking hole 35 simply by moving the adjusting block 27, thereby separating the equipment side plate 3.

[0025] See Figure 3 and Figure 4 The positioning groove 21 is formed inside the locking block 2, the insertion groove 22 is formed on the surface of the locking block 2, the rear end of the positioning groove 21 is connected to the insertion groove 22, the positioning block 25 is slidably connected to the interior of the positioning groove 21, the rear end of the positioning block 25 is arc-shaped, the support spring 28 is set inside the positioning groove 21, the two ends of the support spring 28 abut against the side wall of the positioning groove 21 and the end of the positioning block 25 respectively, the adjustment groove 24 is formed on the upper surface of the locking block 2, the limiting groove 23 is formed between the adjustment groove 24 and the positioning groove 21, the limiting block 26 is slidably connected to the limiting groove 23, the adjustment block 27 is slidably connected to the adjustment groove 24, and the upper and lower ends of the limiting block 26 are fixedly connected to the adjustment block 27 and the positioning block 25 respectively.

[0026] Specifically, when the plug-in block 34 is inserted into the plug-in slot 22, since the end of the plug-in block 34 is inclined and the end of the positioning block 25 is arc-shaped, the plug-in block 34 will directly push the positioning block 25 into the positioning slot 21 until the locking hole 35 slides to the end of the positioning block 25. At this time, the end of the positioning block 25 lacks a limit, and the support spring 28 will push the positioning block 25 outward, inserting the positioning block 25 into the locking hole 35, thereby automatically locking the plug-in block 34 and thus automatically locking the equipment side plate 3.

[0027] Meanwhile, when disassembling the equipment side panel 3, the adjusting block 27 is slid to one side inside the adjusting groove 24. The adjusting block 27 drives the positioning block 25 to slide to one side through the limiting block 26, so that the end of the positioning block 25 is separated from the locking hole 35, thereby unlocking the plug-in block 34 and thus quickly disassembling the equipment side panel 3.

[0028] See Figure 2 and Figure 5 The lower end of the equipment housing 1 is fixedly connected to two sets of first fixing plates 12. The surface of the first fixing plate 12 is provided with a first connecting hole 13. The lower end of the equipment side plate 3 is fixedly connected to a second fixing plate 31. Both the front and rear ends of the second fixing plate 31 are fixedly connected to overlapping plates 32. The surfaces of the second fixing plate 31 and the overlapping plates 32 are provided with second connecting holes 33.

[0029] In addition, after the equipment housing 1 and the equipment side plate 3 are spliced ​​together, the two ends of the first fixing plate 12 abut against the sides of the second fixing plates 31 on the left and right sides respectively. At the same time, the overlapping plate 32 will be stuck on the upper side of the first fixing plate 12, and the second connecting hole 33 on the surface of the overlapping plate 32 will coincide with the first connecting hole 13 on the surface of the first fixing plate 12. When installing and fixing the equipment, screws are passed through the second connecting hole 33 and the first connecting hole 13 for fixing, which further improves the stability of the connection between the equipment housing 1 and the equipment side plate 3.

[0030] The working principle of this utility model is as follows: By inserting the plug block 34 into the plug slot 22, the positioning block 25 will lock the plug block 34 inside the locking hole 35, thereby fixing the equipment side plate 3 to the left and right sides of the equipment housing 1. Conversely, when disassembly is required, the adjusting block 27 is moved to separate the positioning block 25 from the locking hole 35, which can unlock the plug block 34 and then disassemble the equipment side plate 3. This effectively improves the convenience of disassembling the equipment side plate 3, effectively avoids damage to the connecting parts, and improves the service life of the equipment.
