[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments.

[0027] Therefore, the following detailed description of the embodiments of the utility model is not intended to limit the scope of the claimed utility model, but only represents some embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0028] It should be noted that the embodiments in the utility model and the features and technical schemes in the embodiments can be combined with each other without conflict.

[0029] It should be noted that: similar signs and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0030] As Figures 1-4As shown, the present embodiment proposes a quick fixing structure of false twist machine rotating shaft limiting groove, which comprises a support seat 200 for installing rotating shaft 100, and an elastic buckle assembly 300 for locking the position of rotating shaft 100. The support seat 200 is sleeved on one end of the rotating shaft 100, and the limiting protrusions 202 symmetrically arranged on the inner side of the support seat 200 are matched with the limiting grooves 101 symmetrically arranged on the end of the rotating shaft 100, so that the rotating shaft 100 and the support seat 200 can rotate synchronously with the center shaft after they are matched. The outer side of the support seat 200 is symmetrically provided with a threaded sleeve 201 for installing the elastic buckle assembly 300. The elastic buckle assembly 300 comprises a pushing end head 303 connected with the threaded sleeve 201. The outer end of the pushing end head 303 is fixed with a knob 301, and the inner end of the pushing end head 303 is abuttingly connected with a spring 304. The other end of the spring 304 is connected with a limiting end head 302, which is connected with the limiting hole 102 arranged on the end of the rotating shaft 100. The elastic buckle assembly 300 limits the limiting groove 101 in combination with the limiting protrusions 202, so that the rotating shaft 100 can be easily assembled and disassembled by simple plugging and unplugging during installation, and can rotate stably during work, thereby improving the replacement efficiency of the rotating shaft 100 of the false twist machine.

[0031] As shown in Figure 1 , the bottom of the support seat 200 is integrally provided with a mounting ring 203, which is equally provided with positioning holes for fasteners. The mounting ring 203 is fixed with the outer mounting surface by fasteners. The support seat 200 provides a mounting base for the rotating shaft 100. After the mounting ring 203 is fixed, the support seat 200 is fixed at the corresponding position.

[0032] As shown in Figure 2 and 3 , the limiting protrusions 202 are in strip structure, and the limiting grooves 101 arranged on the end of the rotating shaft 100 are in strip shape, which ensures the relative stability of the two after plugging. The length of the limiting groove 101 is greater than the height of the limiting protrusion 202, which allows the rotating shaft 100 to have a certain tolerance range during installation.

[0033] As shown in Figure 4As shown, the knob 301 is provided with anti-skid lines on the side, facilitating manual operation, and the outer diameter of the knob 301 is greater than the inner diameter of the threaded sleeve 201, serving as a limiting function to prevent over-tightening. The threaded sleeve 201 is connected to the inside of the support base 200, and the front end of the limiting end head 302 penetrates the threaded sleeve 201 to the inner ring of the support base 200. The tail of the limiting end head 302 is provided with an annular protrusion, which cooperates with the inner ring of the threaded sleeve 201. The threaded sleeve 201 provides a moving path for the limiting end head 302 while limiting its moving range, avoiding the limiting end head 302 from penetrating the threaded sleeve 201 and falling into the inside of the support base 200, affecting the installation of the rotating shaft 100. The limiting end head 302 is a round head structure, and the limiting hole 102 is correspondingly provided as a round hole, facilitating the quick plug-in installation of the rotating shaft 100. The depth of the limiting hole 102 is less than the length of the limiting end head 302, ensuring that the limiting end head 302 can be completely inserted into the limiting hole 102 and form effective locking.

[0034] Specifically, in use, the fast fixing structure of the false twist machine rotating shaft limiting groove in the embodiment is used as follows: fasteners are used to penetrate the equidistantly distributed positioning holes on the mounting ring 203 to fix it on the outer mounting surface, and ensure that the support base 200 is installed stably without loosening; then, one end of the rotating shaft 100 is inserted into the support base 200, so that the limiting protrusion 202 is aligned with the limiting groove 101 at the end of the rotating shaft 100 and is completely embedded, thereby limiting the relative movement between the rotating shaft 100 and the support base 200, so that they can rotate synchronously around the center axis; subsequently, the advancing end head 303 of the elastic buckle assembly 300 is screwed into the threaded sleeve 201 outside the support base 200, the knob 301 is manually rotated to push the advancing end head 303 to move inward, adjust the compression space of the spring 304, and then adjust the pushing force of the limiting end head 302, so that the limiting end head 302 moves forward along the path in the threaded sleeve 201 until the front end of the limiting end head 302 penetrates the inner ring of the support base 200 and is completely inserted into the limiting hole 102 at the end of the rotating shaft 100. Since the depth of the limiting hole 102 is less than the length of the limiting end head 302, the limiting end head 302 can effectively lock the rotating shaft 100 to prevent it from falling off; after installation is completed, the false twist machine is started to observe the rotation of the rotating shaft 100 in the working state, to ensure that it rotates synchronously with the support base 200 without shaking or abnormal sound. If abnormalities are found, the locking degree of the elastic buckle assembly 300 can be adjusted or the cooperation between the limiting protrusion 202 and the limiting groove 101 can be rechecked; when the rotating shaft 100 needs to be replaced, the rotating shaft 100 is directly pushed outward, so that the limiting end head 302 exits the limiting hole 102, completing disassembly. After a new rotating shaft 100 is replaced, the above steps are repeated for installation.

[0035] All the technical features in the embodiment can be freely combined according to actual needs.

[0036] The above embodiment is a preferred implementation scheme of the present application, in addition to this, the present application can be implemented in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the present application.
