Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to an air conditioner motor cover mounting structure. Background Technology

[0002] The air conditioner motor cover is an important component that protects the motor from dust and moisture corrosion and prevents human contact. Its installation structure directly affects assembly efficiency and safety of use.

[0003] Based on the above, the inventors have discovered the following problems: Currently, mainstream air conditioner motor covers on the market generally adopt a traditional "multiple bolt fixing" structural design to ensure secure installation. Multiple bolt holes are pre-set on the edge of the motor cover, corresponding to the threaded holes on the motor housing. During installation, a screwdriver or wrench is needed to screw the bolts into the threaded holes one by one, using the pre-tightening force of the bolts to achieve a tight fixation between the motor cover and the motor housing. Disassembly requires the reverse operation, unscrewing the bolts one by one. Each time the motor cover is disassembled and reassembled, the "multiple bolt" fixing method reveals its defects of being "cumbersome to operate, inefficient, and dependent on tools," severely restricting work efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an air conditioner motor cover mounting structure in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide an air conditioner motor cover mounting structure to solve the problem mentioned in the background art that the mainstream air conditioner motor covers on the market generally adopt the traditional structural design of "multiple bolts for fixing" in order to ensure the installation is firm.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: An air conditioner motor cover mounting structure includes a main body and a mounting mechanism. The main body includes a housing and a cover. A plurality of positioning holes are circumferentially formed on the outer side of one end of the housing. A plurality of positioning pins are circumferentially mounted on the outer side of one end of the cover, and the positioning holes and positioning pins are interlocked. The mounting mechanism includes a plurality of mounting brackets and a plurality of docking covers. A plurality of mounting brackets are circumferentially positioned on the outer side of one end of the housing, and a plurality of docking covers are circumferentially positioned on the outer side of one end of the cover. A connecting rod is fixedly mounted on one end of each mounting bracket. Movable grooves are formed on both sides of each connecting rod. Wedge-shaped locking blocks are slidably installed inside each movable groove. The connecting rod is interlocked with the inside of the docking cover. Locking grooves are formed on both sides of the docking cover, and the locking grooves are interlocked with the wedge-shaped locking blocks.

[0007] Furthermore, a telescopic frame is fixedly installed on one side of the mounting frame, and sliding grooves are provided on both sides of the telescopic frame. A telescopic rod is slidably installed between each pair of sliding grooves.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the telescopic frame inside the mounting bracket provides a sliding guide for the telescopic rod, and the sliding groove ensures that the telescopic rod moves smoothly and avoids deviation, providing a stable linear motion basis for the subsequent driving of the wedge locking block and ensuring the normal operation of the locking structure.

[0009] Furthermore, one end of the telescopic rod extends through the mounting bracket into the interior of the plug-in rod and is fitted with a trapezoidal block. The two sides of the trapezoidal block are slidably connected to the inclined surfaces of the wedge-shaped locking blocks at their adjacent positions.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the telescopic rod drives the trapezoidal block to move, and the inclined surface of the trapezoidal block slides into contact with the inclined surface of the wedge-shaped locking block. This can convert the linear motion of the telescopic rod into the lateral telescopic motion of the wedge-shaped locking block, realize the automatic insertion or separation of the wedge-shaped locking block and the locking groove, and simplify the operation steps.

[0011] Furthermore, a screw is rotatably connected to one end of the telescopic frame, and a sleeve is embedded in one end of the telescopic rod, with the sleeve and the screw being threadedly connected.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the screw inside the telescopic frame is connected to the sleeve of the telescopic rod by a thread. Rotating the screw can drive the telescopic rod to move along the slide groove. The thread transmission has high precision and can accurately control the moving distance of the telescopic rod, thereby accurately adjusting the extension length of the wedge locking block to ensure that the locking force is appropriate.

[0013] Furthermore, a retainer is fixedly installed on one side of the bottom of the mounting bracket, and a worm gear is rotatably connected to one side of the retainer. The central shaft of one side of the worm gear is connected to one end of the screw.

[0014] The beneficial effects of adopting the above-mentioned further solution are that the cage fixes the position of the worm gear, ensuring stable meshing between the worm gear and the worm. The worm gear is connected to the screw, which can transmit power to drive the screw to rotate, while changing the direction of power transmission. This adapts to the installation position of the handwheel, making it easier for the operator to apply force.

[0015] Furthermore, a worm gear is rotatably connected to one side of the inner top of the mounting bracket, and the worm gear meshes with the worm wheel.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the worm gear and worm wheel transmission have reverse self-locking properties, which can prevent the screw from rotating unexpectedly due to vibration, ensure that the wedge locking block and the locking groove are stably connected, and avoid the machine cover from loosening.

[0017] Furthermore, a handwheel is rotatably connected to one side of the upper end of the mounting bracket, and the bottom central shaft of the handwheel is connected to the top end of the worm gear.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the handwheel at the upper end of the mounting bracket provides the operator with a convenient force-generating component. Turning the handwheel can drive the screw to rotate through the worm gear and worm wheel, thereby controlling the movement of the wedge locking block. No special tools are required, the operation is intuitive and labor-saving, and the efficiency of installing and removing the air conditioner motor cover is improved.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: In this air conditioner motor cover installation structure, the main body shell and the cover are connected by positioning holes and positioning pins to achieve quick positioning, avoid cover displacement during installation, and ensure installation accuracy; the mounting bracket of the installation mechanism cooperates with the docking cover, and after the plug-in rod is inserted into the docking cover, the wedge-shaped locking block and the locking groove are inserted to quickly fix the cover and the shell, prevent the cover from loosening, and achieve convenient and accurate installation of the air conditioner motor cover, improving assembly efficiency and stability; the telescopic rod drives the trapezoidal block to move, and the inclined surface of the trapezoidal block slides into contact with the inclined surface of the wedge-shaped locking block, which can convert the linear movement of the telescopic rod into the lateral telescopic movement of the wedge-shaped locking block, realize the automatic insertion or separation of the wedge-shaped locking block and the locking groove, and simplify the operation steps.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 5 This utility model provides a technical solution: an air conditioner motor cover mounting structure, including a main body 1 and a mounting mechanism 2. The main body 1 includes a housing 101 and a cover 102. A plurality of positioning holes 103 are circumferentially opened on the outer side of one end of the housing 101. A plurality of positioning pins 104 are circumferentially installed on the outer side of one end of the cover 102, and the positioning holes 103 and the positioning pins 104 are inserted into each other. The mounting mechanism 2 includes a plurality of mounting brackets 201 and a plurality of docking covers 202. The plurality of mounting brackets 201 are circumferentially arranged on the... On one side of the housing 101, several docking covers 202 are circumferentially arranged on one side of the cover 102. One end of the mounting bracket 201 is fixedly installed with a plug rod 205. Movable grooves 206 are opened on both sides of the plug rod 205. Wedge-shaped locking blocks 214 are slidably installed inside the movable grooves 206. The plug rod 205 is inserted into the inside of the docking cover 202. Locking grooves 203 are opened on both sides of the docking cover 202. The locking grooves 203 are inserted into the wedge-shaped locking blocks 214.

[0024] As an embodiment of this utility model, a telescopic frame 207 is fixedly installed on one side of the mounting frame 201. The telescopic frame 207 has sliding grooves on both sides of its interior. A telescopic rod 212 is slidably installed between each pair of sliding grooves. The telescopic frame 207 in the mounting frame 201 provides sliding guidance for the telescopic rod 212. The sliding grooves ensure that the telescopic rod 212 moves smoothly and avoids deviation, providing a stable linear motion basis for the subsequent driving of the wedge-shaped locking block 214, and ensuring the normal operation of the locking structure.

[0025] As an embodiment of this utility model, one end of the telescopic rod 212 extends through the mounting bracket 201 into the interior of the plug-in rod 205 and is fitted with a trapezoidal block 213. The two sides of the trapezoidal block 213 are slidably connected to the inclined surfaces of the wedge-shaped locking blocks 214 at their adjacent positions. The telescopic rod 212 drives the trapezoidal block 213 to move, and the inclined surfaces of the trapezoidal block 213 and the wedge-shaped locking blocks 214 slide into contact. This can convert the linear movement of the telescopic rod 212 into the lateral telescopic movement of the wedge-shaped locking blocks 214, thereby realizing the automatic insertion or separation of the wedge-shaped locking blocks 214 and the locking groove 203, simplifying the operation steps.

[0026] As an embodiment of this utility model, a screw 217 is rotatably connected to one end of the telescopic frame 207, and a sleeve 216 is embedded in one end of the telescopic rod 212. The sleeve 216 and the screw 217 are threadedly connected. The screw 217 inside the telescopic frame 207 is threadedly connected to the sleeve 216 of the telescopic rod 212. Rotating the screw 217 can drive the telescopic rod 212 to move along the slide groove. The threaded transmission has high precision and can accurately control the moving distance of the telescopic rod 212, thereby accurately adjusting the extension length of the wedge locking block 214 to ensure appropriate locking force.

[0027] As an embodiment of this utility model, further, a retainer 208 is fixedly installed on one side of the bottom of the mounting bracket 201. A worm gear 209 is rotatably connected to one side of the retainer 208. The central shaft of one side of the worm gear 209 is connected to one end of the screw 217. The retainer 208 fixes the position of the worm gear 209 to ensure stable meshing between the worm gear 209 and the worm 210. The worm gear 209 is connected to the screw 217 and can transmit power to drive the screw 217 to rotate. At the same time, it changes the direction of power transmission to match the installation position of the handwheel 211, making it convenient for the operator to apply force.

[0028] As an embodiment of this utility model, further, a worm gear 210 is rotatably connected to one side of the inner top of the mounting bracket 201. The worm gear 210 and the worm wheel 209 mesh with each other. The transmission between the worm gear 210 and the worm wheel 209 has a reverse self-locking property, which can prevent the screw 217 from rotating accidentally due to vibration, ensure that the wedge-shaped locking block 214 and the locking groove 203 are stably inserted, and prevent the cover 102 from loosening.

[0029] As an embodiment of this utility model, a handwheel 211 is rotatably connected to one side of the upper end of the mounting bracket 201. The bottom center shaft of the handwheel 211 is connected to the top end of the worm gear 210. The handwheel 211 at the upper end of the mounting bracket 201 provides a convenient force-generating component for the operator. Rotating the handwheel 211 can drive the screw 217 to rotate through the worm gear 210 and worm wheel 209, thereby controlling the action of the wedge locking block 214. No special tools are required, the operation is intuitive and labor-saving, and the installation and disassembly efficiency of the air conditioner motor cover is improved.

[0030] Specifically, the working principle of this air conditioner motor cover mounting structure is as follows: In use, first align the positioning pin 104 at one end of the cover 102 with the positioning hole 103 at one end of the housing 101 and insert it to achieve quick positioning of the cover 102 and the housing 101. Simultaneously, align the mating cover 202 on the cover 102 with the insertion rod 205 on the mounting bracket 201 on the housing 101, allowing the insertion rod 205 to insert into the mating cover 202. Then, rotate the handwheel 211 at the upper end of the mounting bracket 201. The handwheel 211 drives the worm gear 210 to rotate, and the worm gear 210 meshes with the worm wheel 209 on the retainer 208, driving the worm wheel 209 to rotate. The worm wheel 209 drives the screw 217 connected at one end to rotate within the telescopic bracket 207. The screw 217 and the sleeve 216 on the telescopic rod 212... The threaded connection converts the rotational motion into linear motion of the telescopic rod 212 along the sliding groove of the telescopic frame 207. The trapezoidal block 213 at one end of the telescopic rod 212 moves accordingly. The inclined surfaces on both sides of the trapezoidal block 213 slide into contact with the inclined surfaces of the wedge-shaped locking block 214 in the movable groove 206 of the insertion rod 205, pushing the wedge-shaped locking block 214 to extend laterally and insert into the locking groove 203 of the docking cover 202. Because the worm gear 210 and the worm wheel 209 have reverse self-locking properties, the screw 217 can be prevented from rotating accidentally, ensuring that the wedge-shaped locking block 214 is stably engaged, and finally achieving a firm installation of the cover 102 and the housing 101. When disassembling, rotating the handwheel 211 in the opposite direction will drive the wedge-shaped locking block 214 to retract through the above-mentioned transmission structure. After unlocking, the cover 102 and the housing 101 are separated.

[0031] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
