Description

Technical Field

[0001] This utility model belongs to the field of sewing machine technology, and in particular relates to a sewing machine head and a sewing machine. Background Technology

[0002] Machines, especially sewing machines, typically have many adjustment holes on the machine head for making adjustments. However, to ensure optimal machine performance, the internal space needs to be kept clean. Therefore, these adjustment holes are usually sealed with plugs to prevent external dust and impurities from entering the machine.

[0003] For example, the flatbed sewing machine, as the most basic and commonly used sewing machine in garment production, requires frequent adjustments to the presser foot height and needle position according to different work needs. Therefore, operators need to regularly remove the plugs on the adjustment holes to adjust the presser foot height adjustment screws and needle bar height adjustment screws inside the machine head. However, because current technology uses independently plugged-in plugs, operators often have nowhere to put them after removal and simply leave them aside. Consequently, in actual work scenarios, the plugs are frequently lost due to various factors, causing the adjustment hole to fail to seal. Prolonged open operation prevents the machine's internal cleanliness from being maintained, leading to dust and fiber accumulation inside, which can eventually cause machine malfunctions. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a sewing machine head and a sewing machine to solve the problem that the hole plug on the sewing machine head is easily lost, thereby affecting the performance and service life of the sewing machine.

[0005] To achieve the above and other related objectives, one aspect of this utility model provides a sewing machine head, including a head body, an elongated groove that does not penetrate the interior of the head body, an adjustment hole on the bottom wall of the elongated groove, the adjustment hole communicating with the interior of the head body and corresponding to the position of an adjustment screw inside the head body; and a plug that is slidably engaged in the elongated groove.

[0006] Furthermore, the elongated groove includes an upper groove and a lower groove, wherein the width of the lower groove is greater than the width of the upper groove, and the length of the lower groove is greater than the length of the upper groove. A slot is formed at the connection between the upper groove and the lower groove. The plug includes an upper section, a middle section, and a lower section, wherein the diameters of the upper section and the lower section are both greater than the diameter of the middle section. The lower section is slidably engaged in the slot, and the middle section is slidably engaged in the upper groove.

[0007] Furthermore, the plug is made of a flexible material.

[0008] Furthermore, the plug is made of rubber.

[0009] Furthermore, the angle between the length direction of the elongated groove and the horizontal direction is 30° to 80°, and the adjustment hole is located at the end of the elongated groove with a lower height.

[0010] Furthermore, the elongated groove is provided on the head cover plate of the head body.

[0011] Furthermore, the diameter of the plug is larger than the diameter of the adjustment hole.

[0012] As described above, the sewing machine head of this invention has the following beneficial effects: Since the plug is slidably secured within the elongated groove, when adjusting the adjusting screw inside the machine head body, the plug can be pushed to slide within the groove, removing it from the adjustment hole position and exposing the hole for the operator to adjust. After adjustment, the plug is pushed again, sliding along the groove to the adjustment hole position to cover it. Therefore, compared to the prior art, when adjusting the adjusting screw inside the sewing machine head of this invention, it is no longer necessary to remove the plug from the machine head; simply pushing the plug along the groove is sufficient. This effectively avoids the problem of the plug easily being lost, thus keeping the machine interior clean and ensuring the sewing machine's performance and lifespan.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] Please see Figures 1 to 6 It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0044] The first aspect of this utility model provides a sewing machine head, such as... Figure 1 and Figure 2 As shown, in this embodiment, the sewing machine head includes a head body 10 and a plug 101. The head body 10 has an elongated groove 11 that does not penetrate the interior of the head body 10. An adjustment hole 100 is provided on the bottom wall of the elongated groove 11. The adjustment hole 100 is connected to the interior of the head body 10 and corresponds to the position of the adjustment screw inside the head body. The plug 101 is slidably engaged in the elongated groove 11.

[0045] The beneficial effects of this sewing machine head are as follows: Since the plug 101 is slidably mounted in the elongated groove 11, when adjusting the adjusting screw inside the machine head body, the plug 101 can be pushed to slide within the groove 11, removing it from the adjustment hole 100 and exposing it for the operator to adjust. After adjustment, the plug 101 is pushed again, sliding along the groove 11 to the adjustment hole 100 to cover it. Therefore, compared to the prior art, when adjusting the adjusting screw inside the sewing machine head, it is no longer necessary to remove the plug 101 from the machine head; simply sliding it along the groove 11 is sufficient. This effectively avoids the problem of the plug 101 being easily lost, thus keeping the machine's interior clean and ensuring the sewing machine's performance and lifespan.

[0046] Furthermore, to improve the stability of the plug 101 in the elongated groove 11 when it slides within the groove, preferably, as follows: Figure 3 and Figure 4 As shown, in this embodiment, the elongated groove 11 includes an upper groove 111 and a lower groove 112. The width of the lower groove 112 is greater than the width of the upper groove 111, and the length of the lower groove 112 is also greater than the length of the upper groove 111. This forms a slot 110 at the connection between the upper groove 111 and the lower groove 112. Correspondingly, the plug 101 includes an upper plug section 1011, a middle plug section 1012, and a lower plug section 1013. The diameters of the upper plug section 1011 and the lower plug section 1013 are both greater than the diameter of the middle plug section 1012. The lower plug section 1013 is slidably engaged in the slot 110, and the middle plug section 1012 is slidably engaged in the upper groove 111. With this configuration, the upper section 1011 and the lower section 1013 of the plug 101 can clamp the upper groove 111 of the long groove 11, effectively preventing the plug 101 from falling out of the long groove 11, thereby greatly improving the stability of the plug 101 in the long groove 11.

[0047] Furthermore, in order to improve the sealing effect of the plug 101 on the adjustment hole 100, in this embodiment, the diameter of the plug 101 is larger than the diameter of the adjustment hole 100. Specifically, in this embodiment, the diameter of the lower section 1013 of the plug is larger than the diameter of the adjustment hole 100. With this setting, the plug 101 can completely and effectively cover the adjustment hole 100, thereby improving the sealing effect on the adjustment hole 100.

[0048] Furthermore, to facilitate the installation and removal of the plug 101, preferably, in this embodiment, the plug 101 is made of a flexible material; more preferably, in this embodiment, the plug 101 is made of rubber. This makes it easy to insert the plug 101 into the slot 110.

[0049] Specifically, in this embodiment, the angle between the length direction of the elongated groove 11 and the horizontal direction can be 0° to 90°, that is, in this embodiment, the elongated groove 11 can be horizontal, inclined, or vertical. Preferably, to make it more convenient for the operator to adjust the adjusting screws inside the machine head body, such as... Figure 2 As shown, in this embodiment, the angle between the length direction of the elongated groove 11 and the horizontal direction is 30° to 80°, that is, the length of the elongated groove 11 extends obliquely upward, and the adjustment hole 100 is located at the end of the elongated groove 11 with a lower height. This arrangement, as... Figure 1 and Figure 5 As shown, when the machine head body 10 is in a flat position, if it is necessary to adjust the adjusting screw inside the machine head body 10, the operator pushes the plug 101 upwards along the long groove 11 to push the plug 101 away from the adjustment hole 100, thereby exposing the adjustment hole 100 for adjustment of the adjusting screw inside the machine head body 10. After adjustment, the operator releases the plug 101, which will automatically slide down to the lower end of the long groove 11, i.e., the adjustment hole 100, due to its own gravity. This eliminates the need for the operator to manually push the plug 101 back to its original position, saving operation time and preventing the operator from forgetting to reset the plug 101 after adjustment. When it is necessary to flip the machine head body 10 for adjustment, as... Figure 6 As shown, when the sewing machine head body 10 is flipped upwards, the end of the long groove 11 with the adjustment hole 100 rotates to a higher position. At this time, the hole plug 101 will automatically slide downwards from the position of the adjustment hole 100 due to its own gravity, thereby automatically opening the adjustment hole 100. After the adjustment is completed, when the sewing machine head body 10 is returned to its original position, the position of the adjustment hole 100 rotates to a lower position. At this time, the hole plug 101 will automatically slide down to the position of the adjustment hole 100 under its own gravity to cover the adjustment hole 100. Therefore, when the sewing machine head of this utility model is adjusted to adjust the internal adjustment screw, the operator no longer needs to manually move the hole plug 101. The operation is convenient, saves operation time, and also avoids the problem of the operator forgetting to reset the hole plug 101 after the adjustment is completed.

[0050] Preferred, such as Figure 1 As shown, in this embodiment, the elongated groove 11 can be disposed on the head cover plate 102 of the head body 10.

[0051] Specifically, the machine head cover 102 is also provided with heat dissipation holes, which help the air to circulate inside the sewing machine, reduce the temperature of the motor and other parts during long-term operation, and prevent overheating damage.

[0052] Another aspect of this utility model provides a sewing machine, such as Figure 5 and Figure 6 As shown, the sewing machine includes a frame (not shown in the figure), a table 20, and a sewing machine head as described above. The table 20 is disposed on the frame, and the sewing machine head, i.e., the head body 10, is hinged to the table 20. A head support 201 is provided on the table 20. When the sewing machine head is flipped relative to the table 20, the head support 201 is used to support the sewing machine head, i.e., the head body 10.

[0053] The beneficial effects of this sewing machine are the same as those of the sewing machine head described above, so they will not be repeated here.

[0054] Furthermore, such as Figure 5 As shown, in this embodiment, a machine head connecting hook 202 is hinged on the table 20, and a rubber pad 203 is provided at the hinge point between the machine head connecting hook 202 and the table 20. The sewing machine head is connected to the machine head connecting hook 202.

[0055] Furthermore, during sewing work, to facilitate workers in taking measurements as needed, preferably, such as... Figure 5 As shown, in this embodiment, a scale 204 is also provided on the platform 20.

[0056] In summary, the adjustment screws inside the sewing machine head and the machine itself effectively prevent the easy loss of the hole plugs, thus keeping the machine's interior clean and ensuring its performance and lifespan. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0057] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
