Description

Technical Field

[0001] This utility model relates to the field of sewing equipment technology, specifically to a needle plate holder and a sewing machine. Background Technology

[0002] During machine sewing, sewing is completed by winding the top thread and bobbin thread together. The top thread is supplied by the needle on the machine head, while the bobbin thread is generally supplied by a rotary hook or similar device within the needle plate. Because the bobbin thread is of limited length, the needle plate needs to be opened frequently to replace the bobbin when it is fully wound with bobbin thread. Furthermore, there are situations where it may be necessary to open the needle plate for troubleshooting, such as when bobbin thread accumulates inside the needle plate.

[0003] Current technologies typically include a detachable or movable cover plate to allow for removal or opening for cleaning or thread replacement when necessary. However, in existing designs such as CN105088545B and CN205676642U, the cover plate is generally located on the needle plate on the upper surface of the needle plate holder. Because the needle plate needs to retain space for the arrangement and movement of the feed teeth, the area occupied by the cover plate on the needle plate surface is greatly reduced. This results in the corresponding needle plate holder opening being concentrated on the needle plate surface, and the opening size is limited. Therefore, this causes many inconveniences for normal thread replacement and cleaning operations. Utility Model Content

[0004] In view of the problem that the limited space presents certain difficulties in performing related operations by opening the cover plate on the needle plate holder in the prior art, this utility model provides a needle plate holder and a sewing machine.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. In this specification, the dimensions of the drawings do not represent the actual dimensions. They are only used to illustrate the relative positional and connection relationships between the components. Components with the same name or the same reference numeral represent similar or identical structures and are limited to illustrative purposes.

[0027] Figure 1 This is a schematic diagram of the needle plate holder of this application. The vertical direction referred to in this application is determined by the posture of the sewing machine in its installed state; more precisely, it is defined by the direction in which the sewing needle is installed, with the needle tip pointing downwards. The needle plate holder 1 includes a cantilevered main body 12, with a needle plate 11 disposed at the cantilevered end of the main body 12. The needle plate 11 extends from the end of the main body 12, forming a space below the needle plate 11 and outside the end of the main body 12 for mounting internal components 14. The internal components 14 mainly refer to a rotary hook mechanism, etc., located below the needle plate 11. The needle plate holder 1 also includes a cover 13, which is detachably or movably connected to the needle plate holder 1. Figure 1 In the case where the cover 13 is detachably connected, the cover has an opening that matches the needle plate 11 and the main body 12. When closed, the opening of the cover 13 is sealed by the needle plate 11 and the main body 12. The cover 13 essentially surrounds the internal component 14, effectively separating the internal component 14 from the external space. This prevents foreign objects from entering the internal component 14 and avoids safety hazards caused by the exposed moving internal component 14. When it is necessary to process the internal component 14, such as replacing the bobbin thread or troubleshooting, the cover 13 is removed to expose the internal component 14. In this design, the internal component 14 is only obstructed from the top and one side, namely the needle plate 11 at the top and the main body 12 on the side. In other locations, when the cover 13 is removed, the internal component 14 is unobstructed, thus significantly expanding the working space when removing the cover 13, allowing for easy completion of operations involving the internal component 14. Generally speaking, in order to ensure that the cover 13 is fixed in the closed state, the cover 13 can be snapped with the needle plate 11 and / or the receiving body 12, mechanically connected, or repeatedly disassembled through other equivalent means.

[0028] like Figure 2 In the illustrated embodiment, the cover 13 can also be pivotally connected to the needle plate 11 or the main body 12. The cover 13 and the main body 12 can be connected via a pivot 121. The pivot is located at the lower end of the joint between the main body 12 and the cover 13, and the pivot 121 is perpendicular to the vertical direction. In this case, when the cover 13 rotates around the pivot 121, it opens in the vertical plane without interfering with the needle plate 11 or the main body 12.

[0029] Figure 3This is a preferred embodiment of the present application. The cover 13 is movably connected to the end of the main body 12. Specifically, a pivot 121 is fixed on the main body 12, and the cover 13 can rotate about the pivot 121 and move along the overhanging direction of the main body 12. Figure 3 A mechanism for satisfying this movement is shown, wherein the end of the cover 13 that engages with the main body 12 has an ear piece 131 extending toward the main body 12, and a groove 132 is formed on the ear piece 131. When the cover 13 is in the closed state, the groove 132 is formed along the overhang direction of the main body 12. A pivot 121 is fixed to the main body 12, and the pivot 121 is slidably disposed within the groove 132. When opening the cover 13, the cover 13 is first pulled outward along the overhang direction of the main body 12, and then the cover 13 is rotated downward to open, so as to avoid interference between the cover 13 and other components. The operation process when closing the cover 13 is the reverse.

[0030] The surface of the main body 12 has a groove 122 for accommodating the ear piece 131. One edge of the groove 122 is in close contact with the upper edge of the ear piece 131 when the cover 13 is closed, thereby preventing the cover 13 from rotating in the closed state and ensuring that the cover 13 remains in the closed state. The cover 13 engages with the needle plate 11 in the closed state. Figure 4 As shown in the AA-direction diagram, the lower surface of the needle plate 11 is provided with outwardly flared locking feet 111. The opening of the cover 13 facing the needle plate 11 is in a contracted state. The locking feet 111 are engaged and fixed to the opening of the cover 13 in the closed state. During the closing process, the cover 13 is first rotated until the ear piece 131 is parallel to the edge of the groove 122. Then, the cover 13 is pushed into the main body 12 along the direction of the groove 122. During the pushing process, the locking feet 111 enter the opening of the main body 12 to complete the engagement and fixation, preventing the main body 12 from detaching from the needle plate 11 in the vertical direction.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Any modifications and improvements made to the technical solution of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
