Description

Technical Field

[0001] The present application relates to the field of motors, and in particular to a fan coil motor with a stop structure. Background Art

[0002] The fan coil unit is the terminal device of the central air conditioner. The simple working principle of the fan coil unit is that cold water or hot water flows through the threaded copper tube of the surface cooler. Driven by the motor, the fan wheel rotates actively to discharge the cold and heat brought by the cold water / hot water in the copper tube, so that the air is cooled, dehumidified or heated, thereby adjusting the indoor air temperature or humidity.

[0003] At present, most fan coil motors are fixed to the bracket with clamps. For some motors with large starting torque, the clamping force is not enough to fix the motor, which causes the motor to rotate after long-term use. In severe cases, the lead wires may even be cut off. Utility Model Content

[0004] In order to improve the problem of poor fixing effect of existing motors, the present application provides a fan coil motor with a stopping structure.

[0005] The present application provides a fan coil motor with a stop structure, which adopts the following technical solution:

[0006] A fan coil motor with a stopping structure comprises a motor body and a bracket, wherein the bracket is U-shaped, the horizontal end of the bracket is in contact with a mounting surface and is connected via a connecting piece, the two vertical ends of the bracket are connected to the horizontal end of the bracket, the vertical end of the bracket extends vertically upward, and the two ends of the motor are respectively and one-to-one mounted on the two vertical ends of the bracket; a limit plate is fixedly provided on the top of the horizontal end of the bracket, a stop screw is provided on both sides of the limit plate, one end of the stop screw abuts against the limit plate, and the other end of the stop screw is connected to the outer shell of the motor body, and the two stop screws are arranged in an inverted V shape.

[0007] By adopting the above technical solution, the motor body can be detachably arranged on the bracket. At the same time, through the abutment between the two stop screws and the limit plate, the motor body is provided with stable support and positioning, which greatly reduces the risk of displacement of the motor body due to its own vibration.

[0008] Optionally, a pair of mounting strips are provided on the outer shell of the motor body, and the mounting strips extend along the axial direction of the motor body. A slide groove is provided on the mounting strip, and the cross-section of the slide groove is convex-shaped. A slider is provided in the slide groove, and the slider slides in the slide groove in a fitting manner. The end of the stop screw away from the limit plate is inserted into the slide groove and connected to the slider. A nut is screwed on the upper part of the stop screw, and the nut abuts against the mounting strip.

[0009] By adopting the above technical solution, the cooperation between the slide groove and the slider ensures that the slider will not fall off the slide groove, thereby ensuring that the stop screw can slide in the length direction of the slide groove, and then adjusting the relative position between the two stop screws to adapt to different installation environments and improve the stopping effect on the motor body.

[0010] Optionally, one end of the slide groove is connected to a side wall of the mounting strip, and the other end of the slide groove is not connected to the other side wall of the mounting strip, and the end of the slider and the stop screw slide into the slide groove from one end of the slide groove and contact with the other end of the slide groove.

[0011] By adopting the above technical solution, the slider and the stop screw can slide into the slide groove through one end of the slide groove connected to the mounting strip, which is convenient for quick installation and quick adjustment of the slider and the stop screw.

[0012] Optionally, a cover plate is provided on the other side of the mounting bar, and the cover plate and the mounting bar are locked by a locking bolt. An adjusting bolt is screwed on the middle part of the cover plate, one end of the adjusting bolt is located on the outside of the slide groove, and the other end of the stop screw extends into the slide groove and abuts against the slider.

[0013] By adopting the above technical solution, the cover plate serves to cover the side of the slide groove connected to the mounting strip, and after the locking bolt locks the cover plate, the slider and the stop screw will not be able to slide out of the slide groove. Furthermore, after the cover plate is installed, the adjusting screw can be rotated to achieve a resistance effect on the slider, ensuring that the slider can be reliably fixed in the slide groove.

[0014] Optionally, an adjustment mechanism is provided at the end of the stop screw away from the slide slot, and the adjustment mechanism includes a connecting block, a rotating seat and a rotating rod, one end of the connecting block is connected to the stop screw via a first spring, the rotating seat is connected to the other end of the connecting block, and the rotating rod is connected to the rotating seat and can rotate around the rotating seat.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] Figure 1 is a schematic three-dimensional diagram of the present application, Figure 2 This is a reference diagram of the assembly status of the motor body and the stop screw. Figure 1 and Figure 2 A fan coil motor with a stop structure comprises a motor body 1 and a U-shaped bracket 2. The horizontal end of the bracket 2 is stably mounted on a preset mounting surface through a connecting piece, and the connecting piece can be an anchor bolt or a mortise and tenon structure, and the two vertical ends of the bracket 2 extend vertically upward to erect the motor body 1. In particular, the two ends of the motor body 1 are respectively and one-to-one mounted on the two vertical ends of the bracket 2, thereby ensuring the stability of the motor body 1. At the top of the horizontal end of the bracket 2, a limit plate 20 is provided, the length of the limit plate 20 is less than the length of the horizontal end of the bracket 2, and a stop screw 3 is provided on each side of the limit plate 20. One end of the two stop screws 3 are in contact with the limit plate 20, and the other end of the two stop screws 3 are connected to the outer shell of the motor body 1. Since the outer shell of the motor body 1 is cylindrical, the two stop screws 3 can present an inverted V-shaped layout and form a clamping effect on the limit plate 20. In this way, when the motor body 1 shakes, the mutual interference between the two stop screws 3 and the limit plate 20 can effectively improve the stability of the motor body 1 and prevent it from shifting due to vibration and other reasons during operation.

[0032] Figure 3 It is a schematic stereogram of the mounting strip, stop screw and adjustment structure. Figure 4 yes Figure 3 Reference diagram of the explosion state. Figure 3 and Figure 4 Combined with Figure 2A pair of mounting bars 4 are provided on the outer shell of the motor body 1. The mounting bars 4 and the motor body 1 can be connected by welding or by a bolt structure. The mounting bars 4 extend along the axial direction of the motor body 1. A slide groove 41 is provided on the side of the mounting bars 4. The side of the mounting bars 4 is arranged opposite to the outer shell of the motor body 1, that is, the side where the mounting bars 4 are connected to the motor body 1 is arranged opposite to the side where the slide groove 41 is provided on the mounting bars 4. One end of the slide groove 41 is located in the middle of the mounting bars 4, and the other end of the slide groove 41 passes through the end face of the mounting bars 4. The end face of the mounting bars 4 is perpendicular to the side face of the mounting bars 4 where the slide groove 41 is provided. In this way, the slider 42 can slide directly from the outside of the mounting bars 4 into the slide groove 41. Furthermore, the cross section of the slide groove 41 is convex, and the outer wall of the slider 42 fits with the inner wall of the slide groove 41. In this way, when the slider 42 slides in the slide groove 41 along the length direction of the slide groove 41, it will not fall out of the slide groove 41. Furthermore, one end of the stop screw 3 abuts against the limit plate 20, while the other end of the stop screw 3 extends into the slide groove 41 and is connected to the slider 42, so that when the stop screw 3 is pushed, the stop screw 3 and the slider 42 can slide in the slide groove 41, thereby realizing the preliminary connection between the stop screw 3 and the motor body 1. At the same time, a nut 30 is provided on the upper part of the stop screw 3, and the nut 30 is tightly abutted against the mounting strip 4. By tightening the nut 30, the slider 42 and the stop screw 3 can be further fixed at any position in the slide groove 41.

[0033] See also Figure 2 and Figure 3 , a cover plate 43 is added to the other side of the mounting bar 4. The cover plate 43 is fastened to the mounting bar 4 by a locking bolt 44, which not only enhances the structural strength of the mounting bar 4, but also provides a more stable installation environment for the motor body 1. In addition, an adjusting bolt 45 is also provided in the middle of the cover plate 43. By rotating the adjusting bolt 45, the length of the adjusting bolt 45 screwed into the slide groove 41 can be adjusted, so that the end of the adjusting bolt 45 located in the slide groove 41 can contact the slider 42, thereby achieving fine adjustment and limitation of the position of the slider 42, improving the setting accuracy of the stop screw 3, and effectively improving the stopping effect of the stop screw 3 on the motor body 1, further improving the use effect and safety of the motor body 1. In order to improve the limiting effect on the slider 42, an adjusting bolt 45 can also be provided on the other side of the mounting bar 4, that is, both ends of the slider 42 are contacted by an adjusting bolt 45.

[0034] An adjustment mechanism 5 is also provided at one end of the stop screw 3 away from the slide slot 41. The adjustment mechanism 5 is composed of a connecting block 51, a rotating seat 52 and a rotating rod 53, and is connected to the stop screw 3 through a first spring 54, and the outer diameters of the connecting block 51 and the stop screw 3 are both smaller than the outer diameter of the first spring 54. Specifically, one end of the first spring 54 is connected to the stop screw 3, and the other end of the first spring 54 is connected to the connecting block 51, and the rotating seat 52 is provided on the side of the connecting block 51 facing away from the first spring 54, and the rotating rod 53 is adaptively provided on the rotating seat 52, and the rotating rod 53 can rotate around the rotating seat 52, so that the stop screw 3 has a certain elastic buffer space when subjected to external force, effectively reducing the influence of external vibration or impact on the motor body 1, thereby extending the service life of the motor body 1. At the same time, the adjustment mechanism 5 further includes a limiting sleeve 55 and a second spring 56. The limiting sleeve 55 is sleeved on the lower outer side of the stop screw 3 and the upper outer side of the rotating rod 53, and the second spring 56 is arranged between the limiting sleeve 55 and the nut 30. Such a layout further enhances the stability and buffering capacity of the stop screw 3, and provides more reliable protection for the motor.

[0035] See also Figure 2 and Figure 4A fin plate 57 is provided at the top of the limiting sleeve 55, and the outer diameter of the fin plate 57 is larger than the outer diameter of the limiting sleeve 55 and also larger than the outer diameter of the nut 30. In this way, when the second spring 56 is sleeved on the stop screw 3 and is located between the nut 30 and the limiting sleeve 55, specifically, one end of the second spring 56 abuts against the bottom of the nut 30, and the other end of the second spring 56 is connected to the top of the fin plate 57. When the second spring 56 is in a naturally extended state, the limit sleeve 55 is in a lower limit position under the push of the second spring 56. Specifically, the upper part of the limit sleeve 55 is sleeved on the lower outer side of the stop screw 3, and the lower part of the limit sleeve 55 is sleeved on the upper outer side of the rotating rod 53. In this way, the limit sleeve 55 can limit the rotation of the rotating rod 53. When the rotating rod 53 needs to be rotated, the limit sleeve 55 is pushed upward to the upper position. Specifically, the limit sleeve 55 is located on the outer side of the stop screw 3, and the rotating seat 52 and the rotating rod 53 are located on the outer side of the limit sleeve 55, and the second spring 56 is in a compressed state, thereby releasing the limiting effect of the limit sleeve 55 on the rotating rod 53. When the limiting sleeve 55 is at the lower limit position, the rotating rod 53 cannot rotate, but can move along its own axial direction. In this way, the movement of the rotating rod 53 and the expansion and contraction of the first spring 54 can achieve the shock absorption and buffering effect between the rotating rod 53 and the limiting rod, and the stop screw 3 can make appropriate buffering and adjustment when subjected to external force, ensuring that the stability and durability of the motor body 1 are enhanced. At the same time, the limiting sleeve 55 can be quickly moved to the upper limit position by pushing up the wing plate 57, so as to facilitate the rotation of the rotating rod 53. After the rotating rod 53 rotates, the limiting sleeve 55 is reset and plays a role in limiting the rotating seat 52, so that the rotating rod 53 cannot rotate, and the limiting effect on the rotating rod 53 is achieved, so that the rotating rod 53 can adapt to different installation environments and ensure the reliable stopping effect on the motor body 1.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
