Detailed Description
The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.
As shown in fig. 1 to 10, a detachable motor front and rear cover assembly has a structure including 2 cover bodies 10, an assembly hole 11 provided on one of the cover bodies 10, a fixed pipe unit 1 provided on the other cover body 10 for supporting or hanging, a slotted unit 2 provided on the other cover body 10, and a detachable pipe unit 3 provided on the slotted unit 2 for supporting or hanging.
In this embodiment, the outer contour of the cover 10 is square, and the cover is provided with an arc surface, an opening 12 and a locking block 13 for mounting the self-powered device d in a conventional manner. In addition, the assembly hole 11 is provided at a suitable thickened portion in the cover 10 in a conventional manner, so as to ensure that such connecting pieces as screws or bolts and nuts can be sufficiently installed and fastened at the assembly hole 11.
Wherein, one of the cover bodies 10 is provided with a fixed pipe unit 1 as a front cover, and the other cover body 10 is provided with a slotting unit 2 and a detachable pipe unit 3 as a rear cover, the distinguishing mode has the advantages that the front cover has relatively small volume, the position of an output working structure installed on a motor d is not easy to interfere, otherwise, the detachable pipe unit 3 can greatly occupy the installation space of the output working structure of the motor d, and the output working structure can be a roller of a washing machine or a fan of a smoke exhaust ventilator.
Also, the term "detachable" as used above means that the detachable pipe unit 3 is detachably mounted on the entire rear cover, and the advantages of this mode include: 1. the space occupied by the whole front and rear cover combination product during storage and transportation is relatively small; 2. compared with the cover body 10, the detachable pipe unit 3 is easier to break and damage, and after the detachable pipe unit is detached, the replacement and maintenance cost of the front cover and the rear cover combination can be greatly reduced.
Finally, in the front and rear cover combination, the front cover and the rear cover are both made of BMC (bulk molding compound), or the front cover is made of aluminum alloy and the rear cover is made of BMC.
The fixing tube unit 1 includes a projection plate 101 provided on an outer side surface of the cover body 10, a mounting hole 102 provided on the projection plate 101, and a first mounting tube 103 provided on the projection plate 101.
In this embodiment, the cover 10, the protruding plate 101 and the first mounting tube 103 are integrally formed, and the inner circumferential surface of the first mounting tube 103 is aligned with the inner circumferential surface of the detachable tube unit 3.
Therefore, after the motor d is assembled and mounted to the front and rear covers, there are generally 3 methods of use:
1. 2 first mounting pipes 103 and 2 detachable pipe units 3 are respectively and directly supported on the inner bottom surfaces of household appliances such as washing machines, smoke exhaust ventilators and the like;
2. as described above, the motor d is used at the lower side, but the first installation pipe 103 and the detachable pipe unit 3 are both sleeved on the ground reinforcing rod b, and the method is the reinforcement of the 1 st type if both contact the inner bottom surface;
3. the motor d is inverted, i.e. used above the inside of the home, and the first installation tube 103 and the detachable tube unit 3 are both sleeved on the hanging rod c, so that the motor d can be stably used.
The cover 10 provided with the fixed pipe unit 1 is also provided with a lead fixing frame 4.
In this embodiment, the wire fixing frame 4 is used to prevent the protruding wires on the motor d from being scattered randomly.
The slotting unit 2 comprises a side slot 201 arranged on the outer end surface of the cover body 10 and a middle slot 202 arranged on the outer end surface of the cover body 10.
In this embodiment, the outer end surface refers to a square exposed surface of the cover body 10, which is not in contact with the motor d, and the slotting unit 2 includes a combined slot with a middle side edge, so that the detachable pipe unit 3 can be fully inserted and installed.
The assembly hole 11 is disposed in the side slot 201.
In this embodiment, the assembly hole 11 needs to be used with a screw or a bolt and nut, and the above positional relationship may enable the mounting structure of the detachable pipe unit 3 to be partially separated from the assembly structure of the cover 10 and the motor d. In other words, a balance is achieved between the transmission of harmful vibrations of the removable pipe unit 3 and the self-reinforcing installation of the removable pipe unit 3.
Finally, for the removable pipe unit 3, it strengthens the mounting structure by the screw at the assembly hole 11, and also reduces the amplitude of the transmitted harmful vibration by the separate plugging effect at the middle socket 202.
In the case of the first mounting tube 103, the vibration is not directly transmitted to the screw member at the assembly hole 11, so that the stability of the assembly structure between the protective cover 10 and the motor d can be improved, and the effective service life can be prolonged.
The side slots 201 are circular in shape, the middle slot 202 is rectangular in shape, and the number of the side slots 201 and the middle slot 202 is 2.
In this embodiment, the mounting structure of the detachable pipe unit 3 on the side slot 201 is a screw connection and an inserting connection, and the mounting structure of the detachable pipe unit 3 on the middle slot 202 is a single inserting connection, so as to avoid vibration on the detachable pipe unit 3 from being directly transmitted to the screw connection piece on the assembly hole 11 as much as possible, and ensure that the overall structure of the motor d plus the front and rear covers has a longer effective service life.
The detachable pipe unit 3 comprises a connecting plate 301, a mounting column 302 arranged on the connecting plate 301 and used for being inserted into the side slot 201, a limiting block 303 arranged on the connecting plate 301 and used for being inserted into the middle slot 202, and a second mounting pipe 304 arranged on the connecting plate 301.
In this embodiment, the first mounting tube 103 is disposed at the lower end of one of the covers 10, and the second mounting tube 304 is disposed at the side end of the other cover 10, and the two tubes are aligned. Thus, the former can be provided only at one end on the side of the projecting plate 101, and the latter can be provided entirely on the bottom side of the connecting plate 301.
The difference between the two is precisely to ensure that the first mounting tube 103 and the second mounting tube 304 are synchronously sleeved with the ground reinforcing rod b or the hanging rod c together.
In addition, the gap between the limiting block 303 and the middle slot 202 needs to be as small as possible, and the gap between the mounting post 302 and the side slot 201 may be appropriately large, because the former is mainly used for transmitting and digesting vibration, i.e. directly transmitted to the cover 10, instead of the screw-coupling member of the assembly hole 11, and the latter is mainly used for screw-coupling the entire detachable pipe unit 3.
The detachable pipe unit 3 further includes connection holes 305 provided on the connection plate 301 and the mounting post 302.
In this embodiment, the screw-coupling member composed of the screw or the bolt and nut sequentially passes through the first assembly hole 11, the second assembly hole 11, and the connection hole 305, so that the detachable pipe unit 3 can be stably installed without transmitting all vibration to the screw-coupling member, and thus the service life of the screw-coupling member for fixing installation can be properly prolonged.
On the other hand, if the detachable pipe unit 3 is simply inserted into the cover 10 without being screwed, although the effect of protecting the screw is the best, the detachable pipe unit 3 itself is likely to be mounted insufficiently stably, so that the above-described optimal compromise is adopted.
The detachable pipe unit 3 further comprises 2 side plates 306 provided on the connection plate 301 and the second installation pipe 304.
In this embodiment, the side plate 306 may not only strengthen the whole detachable pipe unit 3, i.e. strengthen the connection between the connection plate 301 and the second mounting pipe 304, but also make the screw-connection element, such as a nut, on the assembly hole 11 difficult to lose after loosening, i.e. fall into the "groove" surrounded by the side plate 306.
The detachable pipe unit 3 further includes a reinforcing plate 307 provided on both the side plates 306.
In the present embodiment, the reinforcement plate 307 can significantly improve the structural strength of the entire detachable pipe unit 3, and after all, the detachable pipe unit 3 needs to support the weight of the motor d and the rotating work structure to which it is mounted.
The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
