DETAILED DESCRIPTION
[0023] 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 in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figures 1 to 5 The utility model provides a technical solution: a locking machine with a positioning function, comprising a locking machine body 1, a clamping plate 4 is attached to one side of the locking machine body 1, a slide rail 3 is installed above the clamping plate 4 by screws, and a rotating plate 2 is provided below the slide rail 3;
[0025] A clamping block 206 is welded on the top of the rotating plate 2, a rotating shaft 203 is welded on the top of the clamping block 206, a second spring 204 is wound around the outside of the rotating shaft 203, a limiting sleeve 205 is attached to one side of the clamping block 206, a pressing block 202 is wound around one side of the second spring 204, and a fixing block 201 is attached to the outer wall of the pressing block 202;
[0026] A slider 302 is attached to the interior of the slide rail 3, a second threaded rod 301 is attached to the interior of the slider 302, and a rotating handle 303 is welded to one side of the second threaded rod 301;
[0027] A first threaded rod 405 is attached to the inside of the clamping plate 4, an anti-slip pad 404 is attached to the top of the first threaded rod 405, a limiting groove 401 is welded to the top of the clamping plate 4, a first spring 402 is welded to the inside of the limiting groove 401, and a movable plate 403 is welded to the bottom of the first spring 402.
[0028] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the external structural dimensions of the clamping block 206 are consistent with the internal structural dimensions of the limiting sleeve 205; because the overlocking machine generally welds an elastic band to seal the edge, direct sewing will result in crooked edge repair. Now, the improvement is provided with a rotating plate 2 that can limit the position, so that the sewing thread can be sewn along one side to avoid crooked line repair, and the clamping block 206 can move along the hole of the limiting sleeve 205, can be fixed, and can be folded and stored in a rotating direction for easy use, thereby achieving the effect of moving the rotating plate 2.
[0029] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the rotating shaft 203 forms an elastic structure with the pressing block 202 through the second spring 204; because the overlocking machine generally has an elastic band welded on the edge, direct sewing will result in crooked edge repair. Now, the improvement is that the pressing block 202 can drive the second spring 204 to adjust the distance of the rotating shaft 203, and the rotating shaft 203 can drive the rotating plate 2 connected to the clamping block 206, thereby achieving the function of adjusting the rotating plate 2 and fixing the rotating plate 2.
[0030] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the slider 302 forms a sliding structure with the slide rail 3 through the second threaded rod 301; because the edge banding machine is generally used to bandage the elastic band, some elastic bands are relatively wide, and some are relatively narrow. The existing edge banding machine will use a baffle to prevent the sewing line from being crooked. The existing baffle is fixed in position and the distance cannot be adjusted. It is impossible to bandage the elastic bands of different thicknesses. Now, the slider 302 is improved to be connected to the fixed block 201, and the rotating handle 303 is manually rotated to rotate the second threaded rod 301, driving the slider 302 to move, thereby achieving the movement and adjustment position of the slider 302.
[0031] In this embodiment, Figure 5 As shown, the movable plate 403 forms an elastic structure with the first spring 402 through the limiting groove 401; because the overlocking machine is generally used for locking the edges of various fabrics, most fabrics will have loose edges when cutting, and when the edges are manually sewn, the sewing lines will not be straight. In addition, due to the different thicknesses of the fabrics, the upper plate is fixed, which leads to the need to replace the baffle device when sewing some thicker fabrics. Now, the first spring 402 and the movable plate 403 are arranged inside the limiting groove 401, and the spacing can be flexibly adjusted. The edge is limited and fixed, thereby achieving the effect of fixing the movable plate 403.
[0032] In this embodiment, Figure 1 , Figure 2 and Figure 5As shown, the internal structural dimensions of the clamping plate 4 are consistent with the external structural dimensions of the first threaded rod 405; the overlocking machine is generally used for the overlocking of various fabrics. Most fabrics will have loose edges when cut, and the sewing lines will not be straight when the edges are manually sewn. Now, the improvement is provided with a movable fixed limit groove 401, the clamping plate 4 can be movably adjusted in position, and the first threaded rod 405 rotates to fix the anti-slip pad 404, thereby achieving the effect of fixing the anti-slip pad 404.
[0033] The use method and advantages of the utility model: When the overlocking machine with positioning function is used, the working process is as follows:
[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, first, the pressing block 202 drives the second spring 204, the rotating shaft 203, the clamping block 206 and the rotating plate 2 to move horizontally to one side in sequence, and the pressing block 202 can drive the rotating shaft 203 to rotate clockwise, so that the clamping block 206 is fixed into the hole of the limiting sleeve 205, and the slider 302 is connected to the fixed block 201. The rotating handle 303 drives the second threaded rod 301 to rotate clockwise, so that the slider 302 moves horizontally to one side inside the slide rail 3, and the clamping plate 4 is clamped under the overlocking machine body 1. The first threaded rod 405 drives the anti-slip pad 404 to rotate and fix it clockwise, and the movable plate 403 is connected through the first spring 402.
[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
