DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail in conjunction with the embodiments and drawings. Here, the illustrative embodiments of this application and their descriptions are used to explain this application, but are not intended to limit this application.

[0036] refer to Figures 1 to 7 ,like Figure 1As shown, this embodiment provides a mixed embroidery needle bar frame device for a computer embroidery machine, including at least two needle bar frame bodies 1, an upper crossbeam 11 and a lower crossbeam 12 are provided on the needle bar frame body 1, and a plurality of needle bar holes 13 for allowing needle bars to pass through are opened on the upper crossbeam 11 and the lower crossbeam 12, and two adjacent needle bar frame bodies 1 are spliced together by side panels 14, and the splicing of the two side panels 14 is locked by two locking mechanisms 2.

[0037] Specifically, the locking mechanism 2 is installed on two adjacent side panels 14, and the joints of the two needle bar frame bodies 1 are provided with a first semicircular hole 15, a second semicircular hole 16 and a first through groove 17. The locking mechanism 2 includes a connecting piece and a locking piece. The connecting piece is connected in the two first semicircular holes 15 and the two second semicircular holes 16, and the end of the connecting piece extends into the two first through grooves 17. The locking piece is locked at the end of the connecting piece from the two first through grooves 17 to connect the two side panels 14, thereby realizing the rapid splicing of two adjacent needle bar frame bodies 1. In this way, not only can the rapid splicing and use of multiple needle bar frame bodies 1 of the same specification be realized, but also the splicing of multiple needle bar frame bodies 1 of different specifications can be realized, so that the present application can be combined in any number, which is not only efficient in combination but also has a wide range of adaptability.

[0038] like Figure 2 and Figure 3 As shown, the connecting member includes a screw rod 21 , which is installed between the two first semicircular holes 15 and the two second semicircular holes 16 .

[0039] Specifically, the screw 21 includes an internal hexagon head 211 and an external thread section 212 that are integrally connected. The internal hexagon head 211 is accommodated in a countersunk hole 23 surrounded by two first semicircular holes 15, and the external thread section 212 is accommodated in a through hole 24 surrounded by two second semicircular holes 16. The locking piece is threadedly connected to the end of the external thread section 212.

[0040] Preferably, the end of the external thread section 212 extends into the through cavity 25 surrounded by the two first through grooves 17 , and the front end of the through cavity 25 extends to the front surface of the side plate 14 .

[0041] like Figure 3 As shown, the locking member includes a locking block 22 , and a thread is defined in the locking block 22 to be connected to the end of the screw rod 21 .

[0042] In the embodiment of the present application, the first through slot 17 has a first inclined surface 171 , and the locking block 22 has a second inclined surface 221 . The second inclined surface 221 can abut against the first inclined surface 171 .

[0043] like Figure 4As shown, the locking mechanism 2 also includes a first compression spring 3, which is supported between the locking block 22 and the through cavity 25. When the locking block 22 is tightened on the screw 21, the first compression spring 3 is squeezed. Therefore, the elasticity of the first compression spring 3 can increase the tightness of the connection between the locking block 22 and the screw 21, improve the anti-loosening effect, and make the splicing of multiple needle bar frame bodies 1 also have stable connection performance.

[0044] Specifically, a second through groove 222 is provided on the locking block 22, and a top wall 172 is provided on the first through groove 17. The top wall 172 is connected to the first inclined surface 171, and the top wall 172 is a horizontal plane. The first compression spring 3 is supported between the top wall 172 and the second through groove 222; a first internal threaded hole 223 is provided at the bottom of the second through groove 222, and the external thread section 212 is adapted to the first internal threaded hole 223.

[0045] As an optimization solution for the above locking member, Figure 5 As shown, the locking member includes: a moving block 6, an elastic ring 8, a washer 5 and two sliders 4. A second internal threaded hole 61 is opened in the middle of the moving block 6, and the second internal threaded hole 61 is threadedly connected to the external threaded section 212; the elastic ring 8 is sleeved on the external threaded section 212, and the elastic ring 8 and the moving block 6 are abutted; the washer 5 is sleeved on the external threaded section 212; the two sliders 4 are arranged opposite to each other on the washer 5, and the slider 4 has a third inclined surface 41, which abuts against the corresponding first inclined surface 171.

[0046] Preferably, the locking member further includes a plurality of second compression springs 7 , which are annularly connected between the elastic ring 8 and the corresponding accommodating grooves 62 on the moving block 6 .

[0047] like Figure 6 As shown, the elastic ring 8 includes a ring body 81 and an elastic petal body 82 that are integrally connected. A through hole 84 is provided in the center of the ring body 81, and the through hole 84 is sleeved on the external thread section 212. The elastic petal body 82 is supported between the gasket 5 and the movable block 6. A plurality of spacer grooves 83 are provided on the elastic petal body 82. Since the elastic ring 8 will be squeezed when the locking member is locked, the provision of the spacer grooves 83 can increase the deformation ability of the elastic ring 8.

[0048] like Figure 6 and Figure 7 As shown, the elastic petal body 82 includes a connecting arm 821 and an inclined arm 822 . The connecting arm 821 is connected to the edge of the ring body 81 , and the inclined arm 822 extends obliquely from the end of the connecting arm 821 .

[0049] The connecting arm 821 is provided with a protrusion 823 , which abuts against the washer 5 . The tilting arm 822 is provided with a pressing surface 8221 , which abuts against the moving block 6 .

[0050] In the embodiment of the present application, the screw 21 is inserted into the countersunk hole 23 into the through hole 24, and then the slider 4, washer 5, elastic ring 8, second compression spring 7 and moving block 6 are installed in sequence. Finally, by rotating the moving block 6, the second internal threaded hole 61 and the external threaded section 212 can be locked. During the locking process, as the moving block 6 moves upward, the second compression spring 7, elastic ring 8 and washer 5 will move upward, and finally a pair of sliders 4 will be pressed against the first inclined surface 171 along the first inclined surface 171, realizing the pressing of the slider 4 against the through cavity 25, and the second compression spring 7, elastic ring 8 and washer 5 will all be compressed. Therefore, the elastic action of the second compression spring 7, elastic ring 8 and washer 5 can tighten the moving block 6 and the screw 21 and prevent loosening, so that the needle bar frame body 1 can be firmly installed when spliced and combined.

[0051] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Those skilled in the art will appreciate that various modifications and variations of the present embodiment are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
