[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0023] Example:

[0024] A sewing machine hook oil adjustment seat, comprising an oil adjustment seat 1, an oil felt 2, an oil adjustment screw 3, a sealing ring 4, an oil filter plug 5, an arc groove 6, an oil return pipe 7, a plug 8, an oil outlet pipe 9 and an oil inlet pipe 10, such as Figure 1-3The oil quantity adjustment seat 1 is a special-shaped part, a front end side of the oil quantity adjustment seat 1 is provided with an annular groove 6, and a rear end cavity is provided with an oil inlet pipe 10 and an oil outlet pipe 9 connected in sequence, and the oil inlet pipe 10 is connected to an oil return pipe 7.

[0025] As an implementation method in this embodiment, an oil felt 2 is arranged in the annular groove 6, and the felt is used to supply oil to the rotary hook.

[0026] As an implementation method in this embodiment, the oil outlet 9 - 1 of the oil outlet pipe 9 is arranged in the annular groove 6 , and the oil felt 2 is pressed on the oil outlet 9 - 1 , and the capillary phenomenon of the oil felt 2 plays a role in supplying oil to the rotary hook.

[0027] As an implementation method in this embodiment, an oil quantity adjusting screw 3 is provided on the oil inlet pipe 10, and the oil quantity adjusting screw 3 is used to control the oil inlet quantity. A sealing ring 4 is sleeved on the oil quantity adjusting screw 3, and an annular groove is provided on the oil quantity adjusting screw 3, and the sealing ring 4 is sleeved in the annular groove.

[0028] As an implementation method in this embodiment, the oil inlet of the oil inlet pipeline 10 is provided with an oil inlet interface 10-1, and an oil filter plug 5 is provided in the oil inlet pipeline 10. The oil entering the rotary hook is filtered through the oil filter plug 5 to prevent blockage.

[0029] As an implementation method in this embodiment, the oil return pipeline 7 is T-shaped, one end of the oil outlet is connected to the oil return interface 7 - 1 , and the other end is connected to the plug 8 .

[0030] As an implementation method in this embodiment, the annular groove 6 is protrudingly arranged at the front end of the oil quantity adjustment seat 1 .

[0031] Working process of this utility model:

[0032] 1. Supply oil to the rotary hook. The oil flows into the oil inlet pipe 10 through the oil inlet interface 10-1. The oil filter plug 5 filters the oil in the oil inlet pipe 10 and flows out from the oil outlet 9-1. The oil flowing out of the oil outlet 9-1 soaks the oil felt 2 and then supplies oil to the rotary hook. The excess oil flows back to the oil return port through the oil return pipe 7 and flows out through the oil return interface 7-1.

[0033] 2. When the amount of oil in the rotary hook is small, increase the amount of oil in the rotary hook by adjusting the oil adjustment screw 3 upwards to increase the flow rate of the oil inlet pipeline 10.

[0034] 3. When the amount of oil in the rotary hook is large, the amount of oil in the rotary hook can be reduced by adjusting the oil amount adjusting screw 3 downward to reduce the flow rate of the oil inlet pipeline 10.
