Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

As shown in fig. 1, 2 and 3, a connecting structure of a refrigerator compressor and a foot plate, wherein the foot plate is a sheet member formed by stamping a sheet metal, and specifically comprises a welding part 1 at the front side and a fixing part 2 at the rear side, the fixing part is provided with a fixing through hole 21 for a compressor mounting base plate, and the upper surface of the welding part is provided with at least 3 welding protrusions 11, so that a compressor shell can be fixed together with the welding protrusions of the foot plate.

In the present embodiment, the side of the fixing portion away from the compressor housing is referred to as the rear side, and the side of the welding portion close to the compressor housing is referred to as the front side.

Because the upper surface of the welding part is welded with the compressor shell through the welding bulge, the foot plate and the compressor shell are not in surface contact but in point contact through the welding bulge, and therefore the defects of poor contact, false welding and the like caused by shape machining errors during surface contact can be effectively avoided.

When the welding part upper surface is equipped with 3 welding projections, the welding projection can be set to one in the middle of preceding or back, one respectively about the back or preceding, 3 welding projections are isosceles triangle. According to the principle of fixing one surface at three points, the three welding bulges can ensure that the welding bulges are always in a close fit state with the shell of the compressor, and the problem caused by shape deviation is effectively avoided;

or, 4 welding bulges can be arranged on the upper surface of the welding part, and the 4 welding bulges are symmetrically arranged in a rectangular or isosceles trapezoid shape from the left to the right of the central line of the foot plate in the front-back direction, so that the foot plate can be stably and reliably connected with the bottom plate of the compressor. Because the bottom of the compressor shell is a revolving body, when 4 welding bulges which are symmetrically arranged left and right are arranged on the upper surface of the welding part, the reliable attachment and connection between the 4 welding bulges and the compressor shell can be ensured.

Preferably, an arc-shaped bend 12 protruding upwards is arranged at the center line position of the foot plate in the front-back direction. The arc is buckled and is favorable to the elastic bending deformation of sole left and right sides, like this, even the sole exists at small shape deviation when processing manufacturing, we also can make two welding projections of one side and a welding projection and the compressor housing welding of opposite side earlier, and the fourth welding projection this moment and the compressor housing between have small clearance to exist, we can press this welding bellied back, make the sole conveniently produce elastic deformation, fourth welding projection and the laminating of compressor housing this moment, can make this welding projection and compressor housing reliably fixed through spot welding.

Of course, the height of the arc-shaped bend should be lower than the height of the welding projection to avoid the arc-shaped bend interfering with the compressor shell. In addition, 1-2 bolt through holes can be respectively formed in the left side and the right side of the arc-shaped bending part on the fixing part. Thus, after the welding part of the foot plate is welded with the compressor shell and the fixing part is fixedly connected with the compressor mounting bottom plate through the fastening bolts arranged in the bolt through holes at the left side and the right side of the arc bending part, the foot plate is integrally connected with the compressor shell and the compressor mounting bottom plate in the left-right direction, and therefore the foot plate has enough rigidity and bending strength. The arc-shaped bending extending forwards and backwards can effectively improve the strength and rigidity of the foot board in the front and back directions. That is, the arc-shaped bending not only facilitates the foot plate to reliably attach and weld the welding projection and the compressor housing through appropriate deformation, but also increases the strength and rigidity of the foot plate in the front-rear direction.

Further, as shown in fig. 4, a flange 22 extending to the edge of the fixing portion may be disposed at the edge of the welding portion to improve the strength and rigidity of the welding portion and reduce vibration of the compressor during operation.

When the fixing part of the foot plate welded at the bottom of the compressor shell 8 is fixed with the compressor mounting base 5, the fastening bolt 3 arranged on the compressor mounting base upwards penetrates through the bolt through hole and then is in threaded connection with the fastening nut 4, at the moment, the fastening bolt can be loosened firstly, the bolt clamp hole corresponding to the locking clamp is sleeved on the fastening bolt extending out of the fastening nut, and then the fastening bolt is screwed, so that the bolt clamp hole can be tightly sleeved on the upper end of the fastening bolt extending out of the fastening nut. Meanwhile, as the locking clamp is provided with at least 2 bolt clamp holes, the locking clamp cannot rotate, and the bolt clamp holes are provided with internal threads, the bolt clamp holes and the fastening bolts at the moment form threaded connection, so that the locking clamp cannot axially move, further the fastening nuts are prevented from being separated due to looseness, and the reliable connection of the compressor and the compressor mounting base is ensured.

It will be appreciated that we tighten the tightening screw from the side, thus facilitating the installation of the compressor.

It should be noted that the locking clip can be formed by bending a strip, that is, one end of the two clips is connected into a whole, and the other end is disconnected. Preferably, the abutting ends of the two clips may be disposed between adjacent fastening screws therein.
