DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0020] Embodiment:

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides an embroidery thread tensioning mechanism of an embroidery machine thread frame, comprising an embroidery machine frame 1, mounting seats 2 are fixed at both ends of one side of the embroidery machine frame 1, a connecting rod 3 is fixed between two groups of the mounting seats 2, a plurality of groups of fixing clips 4 are fixed on the connecting rod 3, one side of each group of the fixing clips 4 is abutted with a clamping clip 5, the clamping clip 5 is slidably connected with the connecting rod 3, a moving seat 8 is installed on one side of each group of the clamping clips 5, a first spring 13 is fixed on the other side of the moving seat 8, a fixing rod 6 is penetrated through the inner side of the first spring 13, and a clamping groove 15 and a limiting rod 16 are provided between the moving seat 8 and the connecting rod 3;

[0022] The connecting rod 3 is provided with a slide groove 7, and the movable seat 8 is located inside the slide groove 7 and slides. The upper and lower ends of the side close to the clamping clip 5 on most movable seats 8 are fixedly connected with a cross bar 9, and the other end of the cross bar 9 is fixedly connected to the clamping clip 5. A limit rod 16 is passed through the cross bar 9, and the upper end of the connecting rod 3 is provided with a plurality of groups of card grooves 15. The bottom of the limit rod 16 extends into one group of the card grooves 15 and is adapted thereto. A second spring 17 is sleeved on an outer section of the limit rod 16 located below the cross rod 9, and a limit block 18 is fixed to the bottom of the second spring 17, and the limit block 18 is fixedly connected to the limit rod 16;

[0023] A first spring 13 is sleeved on a section of the fixed rod 6 located inside the slide slot 7, one end of the first spring 13 is in contact with the moving seat 8, and the other end of the first spring 13 is fixedly connected to the limiting plate 12, and the limiting plate 12 is fixedly connected to the fixed rod 6;

[0024] When using this device, the position of the fixed rod 6 can be moved to drive the limit plate 12 fixedly connected thereto to move, thereby pushing the first spring 13 to move it and push the moving seat 8 so that the moving seat 8 slides inside the slide groove 7, and the cross bar 9 and the clamping clip 5 move at the same time, so that all the clamping clips 5 can be uniformly controlled to adjust their clamping force. However, when it is necessary to loosen the clamping force of one group of the clamping clips 5 separately, the limit rod 16 can be pulled upward to make it leave the slot 15, and the limit block 18 simultaneously moves upward and compresses the second spring 17, and then the clamping clip 5 is adjusted to the required position. At this time, the limit rod 16 is released again, and the second spring 17 resets itself and pushes the limit block 18 and downward, so that the limit rod 16 is synchronously inserted downward into the corresponding slot 15, and the position of the clamping clip 5 can be individually controlled, which is convenient for use.

[0025] like Figure 1 , Figure 2 , Figure 4 As shown, one group of the mounting seats 2 is provided with a threaded groove 11 inside, and a threaded rod 10 is threadedly connected inside the threaded groove 11, and two ends of the threaded rod 10 extend out of two sides of the mounting seat 2 respectively, and one end of the threaded rod 10 is rotatably connected to the fixing rod 6, and the other end of the threaded rod 10 is fixed with a handle 14; when using the present device, the threaded rod 10 can be driven to rotate by rotating the handle 14, and since the threaded rod 10 is threadedly connected to the threaded groove 11, the threaded rod 10 will move toward or away from the other side of the mounting seat 2 during rotation, driving the fixing rod 6 rotatably connected thereto to move synchronously to the left or right, thereby facilitating the control of the position of the fixing rod 6 and the clamping force of multiple sets of clamping clips 5.

[0026] like Figure 1 , Figure 4 As shown, multiple groups of fixed clips 4 are evenly spaced on the connecting rod 3, the upper and lower ends of the movable seat 8 pass through the slide groove 7 and extend out, and the upper and lower ends of the movable seat 8 extend out of the slide groove 7. A section of the side surface is fixedly connected to the cross bar 9. By fixing the cross bar 9 connected to the clamping clip 5 at the upper and lower ends of the movable seat 8, the stability between the movable seat 8 and the clamping clip 5 can be improved.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
