Description

Technical Field

[0001] This utility model belongs to the field of asynchronous motor technology, and in particular relates to an asynchronous motor with adjustable installation gap. Background Technology

[0002] Asynchronous motors have advantages such as simple structure, convenient manufacturing, use and maintenance, reliable operation, small weight, and low cost. Asynchronous motors have high operating efficiency and good working characteristics. When installing an asynchronous motor, holes are drilled in advance at the positions to be fixed using tools. After the pre-drilled holes are completed, the asynchronous motor can be installed using bolts and nuts. In summary, the problem with the existing technology is that if the position of the pre-drilled holes is offset during the drilling process, the mounting block in the asynchronous motor will not align with the pre-drilled holes, and the bolts and nuts cannot be installed. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides an asynchronous motor with an adjustable installation gap. It has the advantage that the installation block can adjust the gap, and solves the problem that if the position of the pre-drilled hole is offset during the drilling process, the installation block and the pre-drilled hole in the asynchronous motor will not align, and the bolts and nuts cannot be installed.

[0004] This utility model is implemented as follows: an asynchronous motor with adjustable installation gap includes an asynchronous motor, two fixing bars, and four mounting blocks. The two fixing bars are located on both sides of the asynchronous motor. Connecting rods are fixedly connected to opposite sides of the two mounting blocks. Each connecting rod has a threaded groove, and a positioning mechanism is movably connected inside the threaded groove. A connecting block is fixedly connected to the bottom of the asynchronous motor. A rotating shaft is fixedly connected to the front and rear sides of each connecting block. First screws are movably connected to opposite sides of each rotating shaft. A connecting plate is threadedly connected to the surface of each first screw. A fixing seat is fitted onto the end of the first screw away from the rotating shaft. The top of the fixing seat is fixedly connected to the bottom of the asynchronous motor. Rotating blocks are movably connected to opposite sides of each first screw. Rotating grooves that cooperate with the rotating blocks are opened inside the first screws. A closing plate is movably connected inside each mounting block. A sliding rod is movably connected inside the closing plate. Both ends of the sliding rod are fixedly connected to the inner wall of the mounting block. A positioning block is fixedly connected to the top of the closing plate. A snap-fit ​​mechanism is movably connected inside the closing plate.

[0005] In a preferred embodiment of the present invention, the positioning mechanism includes a second screw, which extends through a threaded groove into the interior of the connecting rod. A sliding plate is fixedly connected to the surface of the second screw, and a torsion block is fixedly connected to the right side of the second screw.

[0006] In a preferred embodiment of this utility model, the buckling mechanism includes a support rod, a locking rod fixedly connected to the top of the support rod, the top of the support rod penetrating into the interior of the positioning block and fixedly connected to the locking rod, a pressing rod fixedly connected to the bottom of the support rod, the rear side of the pressing rod penetrating into the outer side of the sealing plate, a tension spring fixedly connected to the rear side of the support rod, and the rear side of the tension spring fixedly connected to the inner wall of the sealing plate.

[0007] As a preferred embodiment of this utility model, a limiting plate is fitted onto the surface of the skateboard, and an anti-slip pad is fixedly connected to the left side of the limiting plate, with the left side of the anti-slip pad contacting the surface of the mounting block.

[0008] As a preferred embodiment of this utility model, the mounting block has a slot inside for use with a locking rod, and the locking rod passes through the outside of the positioning block and extends into the inside of the slot.

[0009] As a preferred embodiment of this utility model, the mounting block has a placement groove inside for use with the connecting plate and the closing plate, the closing plate is located on the rear side of the connecting plate, and the mounting block has a groove inside for use with the closing plate, the groove being connected to the placement groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting a first screw, a connecting plate, a snap-fit ​​mechanism, and an mounting block, can drive two pairs of mounting blocks to move. The user only needs to insert the rotating block into the rotating groove and then rotate the rotating block. The rotating block drives the first screw to rotate, which in turn drives the threaded connecting plate to move. The connecting plate is limited by the snap-fit ​​mechanism. The connecting plate drives the mounting blocks to move, causing the gap between the two pairs of mounting blocks to change. If only a single mounting block needs to move, the user can fix the mounting block that does not need to be adjusted in advance by using the positioning mechanism, and then remove the snap-fit ​​mechanism to not limit the connecting plate. Then, the user rotates the rotating block. Since the connecting plate is not limited by the snap-fit ​​mechanism, the connecting plate drives the mounting block of the snap-fit ​​mechanism to move, thus realizing the movement of a single mounting block.

[0012] 2. This utility model has a positioning mechanism that can fix a single mounting block in place. This prevents the mounting block from moving after the asynchronous motor is installed, as the user can stabilize the mounting block by using the positioning mechanism when the mounting block is not connected to the connecting plate.

[0013] 3. This utility model effectively realizes the connection between the connecting plate and the mounting bracket by setting a positioning mechanism. When the closed plate enters the inside of the placement groove, it is locked into the inside of the groove by the locking rod. In this way, the connecting plate will not come out when it enters the inside of the placement groove, thus achieving the effect of fixing the connecting plate.

[0014] 4. By setting a limiting plate and an anti-slip pad, this utility model increases the friction between the second screw and the mounting block, preventing the mounting block from moving after the second screw rotates with the threaded groove, and preventing the limiting plate from contacting the surface of the fixing strip. In this way, the deeper the second screw penetrates into the threaded groove, the tighter the anti-slip pad of the limiting plate and the fixing strip will be.

[0015] 5. By setting a slot, the sealing plate will not fall off the groove due to gravity after the locking rod is inserted into the slot, thus achieving the effect of fixing the sealing plate.

[0016] 6. This utility model uses a combination of a placement groove and a recess. After the connecting plate enters the placement groove, the sealing plate enters the placement groove from the recess. The sealing plate cuts off the connection plate, allowing the connecting plate to move the mounting block when it moves. Attached Figure Description

[0024] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0025] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 6 As shown in the figure, an adjustable mounting gap asynchronous motor provided by this utility model embodiment includes an asynchronous motor 1, two fixing bars 2 and four mounting blocks 3. The two fixing bars 2 are located on both sides of the asynchronous motor 1. Connecting rods 4 are fixedly connected to opposite sides of the two mounting blocks 3. The connecting rods 4 have threaded grooves 5 inside, and positioning mechanisms 6 are movably connected inside the threaded grooves 5. Connecting blocks 13 are fixedly connected to the bottom of the asynchronous motor 1. Rotating shafts 7 are fixedly connected to the front and rear sides of the connecting blocks 13. First screws 8 are movably connected to opposite sides of the two rotating shafts 7. The surface of the first screws 8 is threaded. A connecting plate 12 is connected to the first screw 8. A fixed seat 9 is fitted at the end of the first screw 8 away from the rotating shaft 7. The top of the fixed seat 9 is fixedly connected to the bottom of the asynchronous motor 1. Rotating blocks 10 are movably connected to opposite sides of the two first screws 8. A rotating groove 11 is opened inside the first screw 8 to cooperate with the rotating block 10. A closing plate 14 is movably connected inside the mounting block 3. A sliding rod 15 is movably connected inside the closing plate 14. The two ends of the sliding rod 15 are fixedly connected to the inner wall of the mounting block 3. A positioning block 16 is fixedly connected to the top of the closing plate 14. A buckling mechanism 17 is movably connected inside the closing plate 14.

[0027] refer to Figure 6 The positioning mechanism 6 includes a second screw 601, which passes through the threaded groove 5 into the interior of the connecting rod 4. A sliding plate 602 is fixedly connected to the surface of the second screw 601, and a torsion block 603 is fixedly connected to the right side of the second screw 601.

[0028] The above solution is adopted: by setting the positioning mechanism 6, the positioning mechanism 6 can fix the individual mounting block 3, and prevent the user from stabilizing the mounting block 3 by the positioning mechanism 6 when the mounting block 3 is not connected to the connecting plate 12, so as to prevent the mounting block 3 from moving after the asynchronous motor 1 is installed.

[0029] refer to Figure 5 The latching mechanism 17 includes a support rod 1701, a latching rod 1702 fixedly connected to the top of the support rod 1701, the top of the support rod 1701 extending through the interior of the positioning block 16 and fixedly connected to the latching rod 1702, a pressing rod 1703 fixedly connected to the bottom of the support rod 1701, the rear side of the pressing rod 1703 extending through the outer side of the closing plate 14, and a tension spring 1704 fixedly connected to the rear side of the support rod 1701, the rear side of the tension spring 1704 being fixedly connected to the inner wall of the closing plate 14.

[0030] The above solution is adopted: by setting the positioning mechanism 6, the connection between the connecting plate 12 and the mounting bracket is effectively realized. After the closing plate 14 enters the interior of the placement groove 22, it is locked into the interior of the slot 20 by the locking rod 1702. In this way, the connecting plate 12 will not come out after entering the interior of the placement groove 22, thus achieving the effect of fixing the connecting plate 12.

[0031] refer to Figure 6 A limiting plate 18 is fitted on the surface of the sliding plate 602. An anti-slip pad 19 is fixedly connected to the left side of the limiting plate 18. The left side of the anti-slip pad 19 is in contact with the surface of the mounting block 3.

[0032] By adopting the above solution, the friction between the second screw 601 and the mounting block 3 is increased by setting the limiting plate 18 and the anti-slip pad 19, preventing the mounting block 3 from moving after the second screw 601 rotates with the threaded groove 5. The limiting plate 18 contacts the surface of the fixing strip 2. In this way, the deeper the second screw 601 penetrates into the threaded groove 5, the tighter the anti-slip pad 19 of the limiting plate 18 and the fixing strip 2 become.

[0033] refer to Figure 5 The mounting block 3 has a slot 20 inside that works with the locking rod 1702. The locking rod 1702 passes through the outside of the positioning block 16 and extends into the inside of the slot 20.

[0034] Using the above solution: by setting the slot 20, after the locking rod 1702 is inserted into the slot 20, the sealing plate 14 will not be dislodged from the groove 21 due to gravity, thus achieving the effect of fixing the sealing plate 14.

[0035] refer to Figure 5 The mounting block 3 has a placement groove 22 inside that works with the connecting plate 12 and the closing plate 14. The closing plate 14 is located behind the connecting plate 12. The mounting block 3 has a groove 21 inside that works with the closing plate 14. The groove 21 is connected to the placement groove 22.

[0036] The above scheme is adopted: by setting the placement groove 22 and the groove 21 in cooperation, the connecting plate 12 enters the interior of the placement groove 22 and then the sealing plate 14 enters the interior of the placement groove 22 from the groove 21. The sealing plate 14 cuts off the connection plate 12, so that the connecting plate 12 can drive the mounting block 3 to move when it moves.

[0037] The working principle of this utility model:

[0038] In use, when it is necessary to adjust the gap between the two pairs of mounting blocks 3, the user inserts the rotating block 10 into the rotating groove 11, and then rotates the rotating block 10, causing the rotating block 10 to drive the first screw 8 to rotate. The first screw 8 drives the threaded connecting plate 12 to move, while the connecting plate 12 is limited by the snap-fit ​​mechanism 17. The connecting plate 12 drives the mounting block 3 to move, and the mounting block 3 drives the connecting rod 4 to move. The top of the connecting rod 4 and the mounting block 3 move along the trajectory of the fixing strip 2. When the appropriate position is reached, the user stops rotating the rotating block 10 and removes the rotating block 10 from the rotating groove 11. When it is necessary to move a single mounting block 3, the user connects it to the threaded groove 5 via the second screw 601. The user presses the lever 1703, which moves the support rod 1701. The support rod 1701 moves the locking lever 1702 while pressing the tension spring 1704. When the locking lever 1702 retracts from the slot 20 into the positioning block 16, the user moves the closing plate 14. The closing plate 14 moves the positioning block 16 while rotating along the trajectory of the slide rod 15. The user then rotates the rotating block 10, which moves the first screw 8 and the connecting plate 12. The connecting plate 12 moves the mounting block 3 of the latching mechanism 17 after installation. The user stops rotating when the appropriate position is reached.

[0039] In summary, this adjustable installation gap asynchronous motor, through the coordinated use of asynchronous motor 1, fixing strip 2, mounting block 3, connecting rod 4, threaded groove 5, positioning mechanism 6, rotating shaft 7, first screw 8, fixing seat 9, rotating block 10, rotating groove 11, connecting plate 12, connecting block 13, closing plate 14, sliding rod 15, positioning block 16, buckling mechanism 17, limiting plate 18, anti-slip pad 19, slot 20, groove 21, and placement groove 22, solves the problem that if the existing pre-drilled hole shifts during drilling, the mounting block in the asynchronous motor will not align with the pre-drilled hole, preventing the bolts and nuts from being installed.
