DETAILED DESCRIPTION

[0024] In order to further understand the content of the utility model, the utility model is described in detail in combination with the drawings and examples. It should be understood that the examples are only used to explain the utility model and not to limit it.

[0025] The following describes the utility model in combination with the drawings and examples. Figures 1-6 The utility model is further described in detail.

[0026] In combination with the drawings, Figures 1-3 shown in the example, an oil receiving box of a sewing machine comprises a box body 110 arranged on a sewing machine base 100, an oil cavity 201 is formed in the upper side of the box body 110, a groove 202 is formed in one side of the box body 110, an oil outlet joint 210 and an oil return joint 220 are arranged in the groove 202 and communicate with the oil cavity 201, an operation notch 301 is arranged on the side of the box body 110 close to the groove 202, a cover body 230 is arranged in the operation notch 301 through a mounting assembly and can be pulled out, a filter screen 310 is arranged in the cover body 230 and is used for filtering the oil returned to the oil cavity 201, and the cover body 230 is pulled out of the operation notch 301 and is used for driving the residue to be discharged from the oil cavity 201.

[0027] In actual use, the upper side of the box body 110 extends outward to form a mounting portion 203, the mounting portion 203 is fixedly mounted on the sewing machine base 100 through screws, in order to avoid the oil in the oil cavity 201 from leaking when the sewing machine head 101 and the sewing machine base 100 are overturned, a sealing washer is arranged on the mounting portion 203, and a sink 204 for mounting the sealing washer is arranged on the mounting portion 203.

[0028] In the embodiment, the sewing machine head 101 and the sewing machine base 100 are turned over, which can drive the box body 110 to turn over, and then the side of the box body 110 on which the cover 230 is installed is arranged upward. At this time, the machine oil in the oil cavity 201 is gathered at the lower side of the cover 230 due to gravity. At this time, the installation of the cover 230 by the installation assembly is released, and the cover 230 is extracted from the operation slot 301, so that the operation slot 301 is opened. At this time, the operator can clean the oil filter screen on the oil pump in the oil cavity 201 through the operation slot 301. Compared with the existing cleaning method of disassembling the entire oil box, the cleaning operation of the oil filter screen on the oil pump in the box body 110 in the embodiment is simple and convenient.

[0029] In the embodiment, when the cover 230 is installed in the operation slot 301, the operation slot 301 can be blocked to prevent the machine oil in the oil cavity 201 from flowing out. The machine oil flowing back to the oil cavity 201 through the filter screen 310 can be filtered, which can further prevent iron filings from entering the oil supply pipeline through the oil pump.

[0030] Specifically, as shown in Figure 6 The cover 230 is provided with a cavity, and the filter screen 310 is arranged on the side wall of the cavity close to the oil cavity 201. The filter screen 310 is arranged between the oil outlet connector 210 and the oil return connector 220. The side wall of the cover 230 below the positioning hole 601 is provided with an oil inlet 602 communicating with the cavity. The machine oil flowing back to the oil cavity 201 enters the cavity through the oil inlet 602.

[0031] The oil inlet 602 is arranged corresponding to the oil return connector 220, so that the machine oil flowing back to the oil cavity 201 through the oil return connector 220 enters the cavity through the oil inlet 602, and then enters the oil cavity 201 after being filtered by the filter screen 310, so that the machine oil can be better sucked into the oil supply pipeline in the sewing machine by the oil pump;

[0032] The filter residue filtered by the filter screen 310 can be left in the cavity, so that when the cover 230 is extracted from the operation slot 301, the filter residue in the cover 230 can be discharged, so that the residue discharge operation is more convenient;

[0033] In the embodiment, in order to better facilitate the discharge of the filter residue from the cavity, the side wall of the cavity facing the bottom wall of the oil cavity 201 is provided with a residue discharge port 603. Therefore, during the extraction of the cover 230, the filter residue in the cavity can be discharged through the residue discharge port 603, so that the residue discharge operation of the cover 230 is more simple and convenient.

[0034] In combination with Figures 4-6As shown, in the embodiment, the sliding cavity 401 is arranged on one side wall of the box body 110 above the recess 202, and a plug column 410 is threadedly connected to the opening of the sliding cavity 401; the installation assembly comprises a sliding column 430 arranged in the sliding cavity 401 through a spring 420, one end of the sliding column 430 is provided with a positioning rod 431 extending into the oil cavity 201, and the cover body 230 extends into the oil cavity 201 through the operation slot 301, and the side wall of the cover body 230 is provided with a positioning hole 601 for the positioning rod 431 to extend into.

[0035] As shown in the embodiment, Figure 5 The side wall of the oil cavity 201 at the operation slot 301 is oppositely provided with a stepped groove 501 for the lap installation of the cover body 230, and the stepped groove 501 is preferably used to realize the pull-out installation of the cover body 230 at the operation slot 301;

[0036] Through the above structure, the outer end of the plug column 410 forms a cross groove, so that the plug column 410 can be detachably installed at the opening of the sliding cavity 401 by using a screwdriver, thereby preferably realizing the installation of the installation assembly in the sliding cavity 401;

[0037] One end of the spring 420 abuts against the plug column 410, and the other end abuts against the sliding column 430, thereby pushing the sliding column 430 to move to the bottom wall of the sliding cavity 401, so that the positioning rod 431 extends through the bottom wall of the sliding cavity 401 to extend into the stepped groove 501; when the cover body 230 extends into the stepped groove 501, the positioning rod 431 extends into the positioning hole 601, so that the cover body 230 can be fixedly installed;

[0038] When the cover body 230 needs to be pulled out, the sliding column 430 is driven to slide in the sliding cavity 401 to retract the positioning rod 431, so that the fixation of the cover body 230 is released.

[0039] In order to facilitate the sliding of the sliding column 430 in the sliding cavity 401 by the operator, in the embodiment, the side surface of the box body 110 close to the recess 202 is provided with a limiting groove 402 communicating with the sliding cavity 401 along the extension direction of the sliding cavity 401, and a pushing column 440 is threadedly connected to the sliding column 430 and extends through the limiting groove 402.

[0040] Through the above structure, the pushing column 440 is pushed along the limiting groove 402, the sliding column 430 is driven to slide and compress the spring 420, the positioning rod 431 is retracted, the fixation of the cover body 230 is released, and the cover body 230 can be pulled out in the stepped groove 501;

[0041] In the embodiment, in order to improve the sealing performance of the installation of the cover body 230 in the stepped groove 501, a sealing ring is arranged between the contact surface of the outer side wall of the cover body 230 and the side wall of the stepped groove 501, so as to improve the installation sealing performance of the cover body 230.

[0042] In order to facilitate the pulling of the cover 230 in the step groove 501, a lifting block 231 is arranged on the outer side wall of the cover 230.

[0043] In this embodiment, in order to further improve the fixing effect of the cover 230 in the step groove 501, a countersunk head bolt 510 for fixing the cover 230 is threadedly connected to the side wall corresponding to the groove 202 of the box body 110. Corresponding to the positioning hole 601, a fixing hole is arranged on the other side wall of the cover 230, and the countersunk head bolt 510 extends into the fixing hole, which is used to fix the cover 230 on the other side of the step groove 501, thereby improving the installation effect of the cover 230 in the step groove 501.
