As shown in fig. 4-9, the mounting assemblies are respectively disposed at two ends of the oil cup 11 in a group to ensure the mounting stability of the oil cup 11 on the machine body 2. Specifically, the mounting assembly comprises a first mounting part 12 and a second mounting part 13, the first mounting part 12 comprises a lug plate part 121 connected to the rear side plate 113 of the oil cup 11, and a mounting gap is formed between the lug plate part 121 and the end plate 114 of the adjacent oil cup 11; the second mounting member 13 includes an extension plate portion 132 and a bearing plate portion 131 connected to a lower end of the extension plate portion 132, the bearing plate portion 131 extending in a direction toward the other second mounting member 13, an upper end of the extension plate portion 132 being for connection with a bottom of the body 2; the carrier plate portion 131 can be inserted into the lower side of the ear plate portion 121 through the rear opening of the installation gap and attached to the ear plate portion 121, and the extension plate portion 132 can abut against the side of the ear plate portion 121 and can rotate by a set angle in the installation gap, the set angle being smaller than 90 °.

In the process of installing the oil cup 11, one set of installation components is firstly assembled, taking the installation component on the left side as an example: moving the position of the oil cup 11 to make the bearing plate part 131 in the set of mounting assemblies face the mounting gap; moving the oil cup 11 from front to back to insert the bearing plate part 131 between the ear plate part 121 and the adjacent end plate 114; thereafter, the oil cup 11 is moved in a direction away from the second mounting member 13 (i.e., the oil cup 11 is moved leftward) so that the carrier plate portion 131 is inserted below the hanger plate portion 121, and at this time, the lower surface of the hanger plate portion 121 abuts against the upper surface of the carrier plate portion 131, and the extension plate portion 132 is positioned between the hanger plate portion 121 and the end plate 114 and abuts against the side edge of the hanger plate portion 121. Thereafter, the mounting assembly at the other end of the oil cup 11 is mounted: the oil cup 11 is horizontally deflected by using the contact point of the extension plate 132 and the hanger plate 121 as a rotation fulcrum, so that the hanger plate 121 at the other end of the oil cup 11 is rotatably inserted between the bearing plate 131 and the bottom surface of the machine body 2 until the first mounting part 12 and the second mounting part 13 are assembled in place.

When the oil cup 11 is disassembled, firstly one group of the mounting components is disassembled: the abutting position of the extension plate part 132 and the ear hanging plate part 121 of the other set of mounting assembly is used as a rotation fulcrum, so that one end of the oil cup 11 which is being dismounted is deflected forwards, the bearing plate part 131 is rotated out of the lower part of the ear hanging plate part 121, the tail end of the oil cup 11 is pulled forwards, the bearing plate part 131 can be separated from the rear opening of the mounting gap, and the mounting assembly at the other end is dismounted.

That is, in the oil cup assembly 1 provided in this embodiment, by providing the installation gap and the extension plate portion 132 capable of rotating a set angle in the installation gap, in the process of detaching and installing one end of the oil cup 11, while the other end of the oil cup 11 can be supported on the bearing plate portion 131 of the corresponding end, and the oil cup 11 can rotate around the other end, so that in the process of detaching and installing the oil cup 11, even if an operator applies an acting force only to the end where the oil cup 11 is being detached, the other end of the oil cup 11 can be kept stable due to the supporting action of the bearing plate portion 131, so that while the stability of detaching and installing the oil cup 11 is ensured, the operator can detach and install the two ends of the oil cup 11 step by step, thereby avoiding the problems of difficult alignment, easy seizure of the oil cup 11, and the like caused by the synchronous detachment and installation of the two ends of the oil cup 11; simultaneously, when oil cup 11 was not dismantled completely, not dismantle the end and support on bearing plate portion 131, stability when oil cup 11 was dismantled can be improved, fluid spills over when avoiding oil cup 11 to dismantle, improves user experience.

In order to further improve the convenience of mounting and dismounting and the stability of mounting the first mounting member 12 and the second mounting member 13, it is preferable that the ear plate portion 121 includes a main plate portion 1211 and a flange portion 1212, the flange portion 1212 is provided to be protruded from a front end of the main plate portion 1211 facing the adjacent end plate 114, a distance between the main plate portion 1211 and the end plate 114 is greater than a plate length, a minimum gap between the flange portion 1212 and the end plate 114 is smaller than the plate length, a distance between the flange portion 1212 and the rear side plate 113 is smaller than a plate width of the carrier plate portion 131 in the front-rear direction, and the flange portion 1212 abuts against the extension plate portion 132. With the arrangement, after the first mounting part 12 and the second mounting part 13 are matched, the flange part 1212 can effectively limit the bearing plate part 131 from directly falling out of the gap between the flange part 1212 and the end plate 114, so as to ensure the assembling stability of the first mounting part 12 and the second mounting part 13; simultaneously, this kind of setting can strengthen the hangers board 121 to bear the weight of board 131 and extend the anticreep of board 132 in the upset process spacing, effectively reduces the probability that deviates from the installation clearance top when second installed part 13 deflects relative first installed part 12.

Further, the side of the ear plate portion 121 facing the adjacent end plate 114 has a first curved surface 12121, the side of the extension plate portion 132 facing the carrier plate portion 131 has a second curved surface 1321, one of the first curved surface 12121 and the second curved surface 1321 is a convex curved surface, and the other is a concave curved surface, and the convex curved surface and the concave curved surface are in relatively rotatable abutment.

Preferably, the height of the extension plate portion 132 is preferably greater than or equal to 2mm and less than or equal to 4mm, so as to ensure that the hanger plate portion 121 is smoothly inserted between the bearing plate portion 131 and the machine body 2, and avoid the problem that the hanger plate portion 121 is easily dropped due to an excessively large gap between the hanger plate portion 121 and the bottom surface of the machine body 2.

The lower surface of the ear plate 121 is preferably inclined downward from front to back, and the upper surface of the bearing plate 131 is inclined downward from front to back, and the inclination angle of the upper surface of the bearing plate 131 is the same as that of the lower surface of the ear plate 121, so that the upper surface of the bearing plate 131 can be attached to the lower surface of the ear plate 121 after the first mounting part 12 and the second mounting part 13 are fitted. By means of the arrangement, after the lug plate part 121 is assembled with the bearing plate part 131, the lug plate part 121 has backward inclined acting force relative to the machine body 2, the oil cup 11 is prevented from inclining forwards under the action of gravity, and even if the oil cup 11 inclines forwards, the oil cup keeps stable due to the limiting effect of the wall body due to the fact that the rear side of the oil cup 11 is the wall body, namely the oil cup 11 stably abuts against the wall body, and the stability of the oil cup 11 after being assembled is further improved.

Further, the inclination angle of the lower surface of the hanger plate portion 121 relative to the horizontal plane is less than 20 °, that is, the inclination angle of the upper surface of the bearing plate portion 131 relative to the horizontal plane is less than 20 °, so as to better ensure the bearing effect of the bearing plate portion 131 on the oil cup 11.
