Detailed Description

The present application is described in further detail below in conjunction with figures 1-5.

The embodiment of the application discloses an improved sewing machine upper thread device.

Referring to fig. 1 and 2, an improved sewing machine upper thread device comprises a machine shell 1, wherein an accommodating shell 2 is fixed on the machine shell 1, a placing shell 3 is fixed inside the accommodating shell 2, a wire core 4 is arranged inside the accommodating shell 2, and an adjusting structure 6 is arranged between the wire core 4 and the accommodating shell 2. Before the sewing machine is used, the upper thread needs to be threaded, the upper thread on the upper thread coil is torn off, then the upper thread is connected with the adjusting structure 6, then the adjusting structure 6 is connected with the machine shell 1, then the upper thread end is connected with the needle head on the sewing machine, and then the sewing machine is used.

Referring to fig. 3-5, the adjusting structure 6 includes a threaded rod 61 disposed inside the accommodating case 2, the threaded rod 61 penetrates through the wire core 4, the accommodating case 2 and the accommodating case 3 in sequence, a lock nut 63 is fixed inside the accommodating case 3, the threaded rod 61 is matched with the lock nut 63, a screwing cap 62 is fixed at the end of the threaded rod 61, a clamping spring 65 is disposed inside the accommodating case 2, and two ends of the clamping spring 65 respectively collide with the wire core 4 and the accommodating case 2. When the upper thread is threaded, the thread core 4 and the clamping spring 65 are sleeved on the threaded rod 61 in sequence, so that the clamping spring 65 is in contact with the thread core 4, the thread core is abutted by the clamping spring 65, then the threaded rod 61 and the clamping spring 65 are placed into the accommodating shell 2, the threaded rod 61 is screwed to be connected with the lock nut 63, when the upper thread is required to be clamped before the sewing machine is used, the screwing cap 62 is rotated to move towards the accommodating shell 3, the thread core 4 is driven to move together when the threaded rod 61 moves, the clamping spring 65 is extruded when the thread core 4 moves, so that the thread pitch of the clamping spring 65 is shortened, and when the thread pitch of the clamping spring 65 is shortened, the upper thread is extruded, and therefore the upper thread is compacted; when needs loosen the face line, reverse rotation twists cap 62, makes its cooperation sinle silk 4 loosen and contradicts to clamp spring 65 to reduce the conflict to the face line, and then realize loosening to the face line, can carry out tensioning to the face line through adjusting structure 6 and adjust the process comparatively conveniently, will press from both sides line mechanism and face line mechanism and unite two into one simultaneously, reduce the part when guaranteeing original function, play cost-saving and save assembly cost.

Referring to fig. 3, an anti-slip rubber ring 64 is fixed to the screw cap 62, and the surface of the anti-slip rubber ring 64 is a groove surface. By providing the anti-slip rubber ring 64 with the groove surface on the screw cap 62, the friction between the finger and the screw cap 62 can be increased when the user rotates the screw cap 62, thereby being more beneficial to the rotation of the threaded rod 61.

Referring to fig. 2 and 3, a threading hole 7 is formed in the casing 1, and a threading spring 8 is fixed inside the threading hole 7. When the upper thread is threaded, the upper thread passes through the threading spring 8, and the threading spring 8 can play a role in guiding the upper thread, so that the tension of the upper thread is more beneficial to adjustment.

Referring to fig. 1 and 3, a jack 9 is formed in the casing 1, a plug spring 10 is inserted into the jack 9, and the plug spring 10 and the casing 1 are slidably arranged. When the extension length of the clamping spring 65 is adjusted, the plug spring 10 can slide in the jack 9, so that the wire core 4 does not follow when the screw cap 62 is rotated, the wire core outgoing line is ensured to be smooth from the surface, and the sewing is ensured to be smooth; meanwhile, the free end of the plug spring 10 is provided with a bending part 11, the shell 1 is internally provided with a hanging part, and the bending part 11 is matched with the hanging part to limit the movable space of the plug spring 10 on the shell 1.

Working principle: before the sewing machine is used, the upper thread needs to be threaded firstly, the upper thread on the upper thread roll is torn off, the wire core 4 and the clamping spring 65 are sleeved on the threaded rod 61 in sequence, so that the clamping spring 65 is in contact with the wire core 4, then the upper thread passes through the clamping spring 65, the clamping spring 65 is used for abutting the upper thread, then the threaded rod 61 and the clamping spring 65 are placed into the accommodating shell 2, the threaded rod 61 is screwed to be connected with the lock nut 63, when the upper thread needs to be clamped by the sewing machine, the screwing cap 62 is rotated to move towards the inside of the accommodating shell 3, when the threaded rod 61 moves, the wire core 4 is driven to move together, the clamping spring 65 is extruded when the wire core 4 moves, so that the screw pitch of the clamping spring 65 is shortened, and when the screw pitch of the clamping spring 65 is shortened, the upper thread is extruded, and therefore the upper thread is pressed; when needs loosen the face line, reverse rotation twists cap 62, makes its cooperation sinle silk 4 loosen and contradicts clamp spring 65 to reduce the conflict to the face line, and then realize loosening to the face line, and simultaneously when threaded rod 61 removes, plug spring 10 can slide inside jack 9, and sinle silk 4 does not follow when making rotate and twist cap 62, and smooth and easy from the smooth and easy of being qualified for the next round of competitions of face guarantee sinle silk guarantees that the sewing is smooth, can carry out tensioning regulation to the face line through adjusting structure 6, and the adjustment process is comparatively convenient.
