Description

Technical Field

[0001] This utility model relates to the field of protective cover technology, specifically a quick-installing main protective cover. Background Technology

[0002] Under the current technological framework, electric motors are typically equipped with a protective cover for safety reasons. The design of the motor cover's installation structure is crucial, requiring a comprehensive consideration of stability, convenience, and adaptability. The design must fully consider factors such as motor type, usage scenario, and protection requirements. Currently, the two most common structural forms are as follows: One type is the bolt-mounted structure. This structure uses bolts or screws to directly fix the protective cover to a pre-set interface on the motor housing. This installation method ensures a tight connection between the protective cover and the motor housing, providing excellent stability.

[0003] The second type is the snap-on installation structure. The elastic snaps precisely engage with the grooves or protrusions on the motor housing to secure the protective cover. The biggest advantage of this structure is its ease of installation, significantly reducing installation time. However, due to its elastic nature, its fixing strength is limited.

[0004] However, both of the above installation structures have certain limitations. While bolt-mounted structures offer stable fixation and high structural strength, the installation process is relatively cumbersome, requiring tools and increasing installation difficulty and time costs. Clip-on installation structures, while convenient to install, are relatively weak in structural strength and cannot withstand significant external impacts.

[0005] In view of this, in order to effectively address the shortcomings of the existing installation structure, it is urgent to develop a new type of motor body protective cover installation structure that can not only ensure the installation and fixing strength, ensuring that the protective cover can be firmly and reliably fixed to the motor under various working conditions, but also have convenient installation characteristics, improve installation efficiency, and reduce installation difficulty. Utility Model Content

[0006] The purpose of this invention is to provide a quick-installing main body protective cover to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-installing main protective cover, comprising a housing, a rotor movably disposed inside the housing via bearings, a connecting sleeve disposed on one side of the housing surface, a protective cover sleeved on the outside of the connecting sleeve, a fixing mechanism disposed between the protective cover and the connecting sleeve, the fixing mechanism comprising a sliding groove, a retaining groove, a fixing ring, a rotating block, and a protruding block, the outer surface of the connecting sleeve having a sliding groove, a retaining groove disposed on one side of the sliding groove on the surface of the connecting sleeve, fixing rings fixedly disposed on both sides of the surface of the protective cover, a rotating block movably disposed inside the fixing ring via bearings, so that the rotating block can rotate inside the fixing ring, and a protruding block fixedly disposed on one side of the surface of the rotating block.

[0008] Preferably, a knob is provided on the outer surface of the rotating block, which allows the rotating block to be easily rotated to adjust the position of the protrusion. When the horizontal position of the protrusion is aligned with the slide groove, the protective cover can be pulled out for disassembly or installation; at this time, if Figure 4 As shown, when the protrusion is as Figure 5 As shown, the protrusion and the slide are misaligned, and the protective cover cannot be disassembled at this time, thus completing the fixation of the protective cover. In other words, the disassembly and installation of the protective cover of this device can be controlled by rotating the protrusion without any tools, making it easy to operate; and after fixation, the protrusion has a better fixing effect than the elastic buckle.

[0009] Preferably, the outer surface of the knob is provided with an anti-slip groove, which allows the knob to be rotated easily.

[0010] Preferably, the outer surface of the knob is provided with an indicator arrow, which allows the operator to easily determine the position of the protrusion at this time, whether it is misaligned with the upper end of the slide or aligned with the lower end of the slide; the direction pointed to by the indicator arrow is the position of the protrusion at this time.

[0011] Preferably, a positioning groove is provided on the outer surface of the upper end of the connecting sleeve, and a positioning block is fixedly provided on the upper end of the inner side of the housing. When the housing is fitted onto the outer side of the connecting sleeve, the protrusion only serves to prevent the protective cover from being pulled out, while the positioning groove and the positioning block can prevent the protective cover from rotating after they are engaged with each other.

[0012] Preferably, a permanent magnet is embedded in the upper part of the rotating block, and iron blocks are embedded in both the upper and lower parts of the fixing ring. The permanent magnet of this device can fix the angle of the protrusion by attracting the iron blocks at the upper or lower end, so as to ensure that the rotating block and the protrusion do not easily rotate when there is no human operation. The rotating block and the fixing ring of this device can be made of engineering plastic material, which can resist corrosion while ensuring sufficient structural strength and improving service life.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The protective cover of this utility model can be disassembled and installed by simply rotating the protruding block. Compared with screw installation, no tools are required and there is no need to tighten each screw to the predetermined torque. The operation is convenient. Moreover, after fixing, the protruding block has a better fixing effect than the elastic buckle and the fixing strength is higher.

[0014] 2. This utility model uses a magnetic attraction method to position the protrusion. That is, after the rotating block and the protrusion rotate 180 degrees each time, there will be a noticeable attraction. The operator can then judge that the protrusion has rotated into place. This makes it easier to adjust and position the protrusion, thus making it convenient for operators to use. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] Please see Figure 1-7 This utility model provides a technical solution: a quick-installing main protective cover, including a housing 1, a rotor 2 movably mounted inside the housing 1 via bearings, a connecting sleeve 3 on one side of the surface of the housing 1, a protective cover 4 fitted on the outside of the connecting sleeve 3, and a fixing mechanism between the protective cover 4 and the connecting sleeve 3. The fixing mechanism includes a sliding groove 5, a slot 6, a fixing ring 7, a rotating block 8, and a protrusion 9. The outer surface of the connecting sleeve 3 has a sliding groove 5, and a slot 6 is provided on one side of the sliding groove 5. Fixing rings 7 are fixedly mounted on both sides of the surface of the protective cover 4. A rotating block 8 is movably mounted inside the fixing ring 7 via bearings, allowing the rotating block 8 to rotate inside the fixing ring 7. A protrusion 9 is fixedly mounted on one side of the surface of the rotating block 8.

[0019] A knob 10 is provided on the outer surface of the rotating block 8. The rotating block 8 can be easily rotated via the knob 10 to adjust the position of the protruding block 9. When the horizontal position of the protruding block 9 is aligned with the sliding groove 5, the protective cover 4 can be pulled out for disassembly or installation. Figure 4 As shown, when the protrusion 9 is as Figure 3 As shown, the protrusion 9 and the slide 5 are misaligned, and the protective cover 4 cannot be disassembled at this time, thus completing the fixation of the protective cover 4. In other words, the disassembly and installation of the protective cover 4 of this device can be controlled by rotating the protrusion 9 without any tools, making it easy to operate; and after fixation, the protrusion 9 has a better fixing effect than the elastic buckle. The outer surface of the knob 10 is provided with an anti-slip groove, which allows the knob 10 to be rotated easily. The outer surface of the knob 10 is provided with an indicator arrow 11. The indicator arrow 11 can help the staff to determine the position of the protrusion 9 at this time, whether it is misaligned with the upper end of the slide 5 or aligned with the lower end of the slide 5; the direction pointed to by the indicator arrow 11 is the position of the protrusion 9 at this time. The upper outer surface of the connecting sleeve 3 is provided with a positioning groove 12, and the upper part of the housing 1 is fixedly provided with a positioning block 13. When the housing 1 is sleeved on the outside of the connecting sleeve 3, the protrusion 9 only serves to prevent the protective cover 4 from being pulled out, while the positioning groove 12 and the positioning block 13 can prevent the protective cover 4 from rotating after they are engaged with each other. The upper end of the rotating block 8 is embedded with a permanent magnet 14, and the upper and lower ends of the fixing ring 7 are both embedded with iron blocks 15. The permanent magnet 14 of this device can fix the angle of the protrusion 9 by attracting the iron blocks 15 at the upper or lower ends, so as to ensure that the rotating block 8 and the protrusion 9 will not easily rotate due to mechanical vibration when there is no human operation. The rotating block 8 and the fixing ring 7 of this device can be made of engineering plastic material, which can resist corrosion while ensuring sufficient structural strength and improving service life.

[0020] Working principle: When using this device, the position of the protruding block 9 is adjusted by rotating the rotating block 8 to control whether the protective cover 4 can be removed. The rotating block 8 can be easily rotated by the knob 10 to adjust the position of the protruding block 9. When the horizontal position of the protruding block 9 is aligned with the slide groove 5, the protective cover 4 can be pulled out for removal or installation; at this time, if Figure 4 As shown, when the protrusion 9 is as Figure 3 As shown, the protrusion 9 and the slide 5 are misaligned, and the protective cover 4 cannot be disassembled. The protrusion 9 is engaged inside the slot 6, thus fixing the protective cover 4. In other words, the disassembly and installation of the protective cover 4 of this device can be controlled by rotating the protrusion 9. Compared with screw installation, no tools are required, and it is not necessary to tighten each screw to the predetermined torque, making the operation more convenient. Moreover, after fixing, the protrusion 9 has a better fixing effect than the elastic buckle and a higher fixing strength. The device uses magnetic attraction to position the protrusion 9. In other words, after rotating block 8 and protrusion 9 rotate 180 degrees each time, there will be a noticeable attraction, and the operator can judge that the protrusion 9 has rotated into place. This makes it easy to adjust and position the protrusion, thus making it convenient for operators to use.
