DETAILED DESCRIPTION

[0025] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Example 1

[0027] A sinking triangle structure of a flat knitting machine includes a sinking base plate 1, on which a sinking triangle assembly 2 that can move up and down is installed, and also includes a front guide plate 3 and a rear guide plate 4. The front guide plate 3 and the rear guide plate 4 are both provided with sinking triangle holes 5, and the sinking triangle holes 5 are all horizontal long holes. The sinking triangle holes 5 include an upper stroke section and a lower stroke section that are interconnected and located on different planes. A bearing 20 is installed on the sinking triangle assembly 2, and the bearing 20 cooperates with the sinking triangle hole 5 and drives the sinking triangle assembly 2 to slide in the sinking triangle hole 5 and move up and down through the front guide plate 3 and the rear guide plate 4 that move left and right.

[0028] The bearing 20 on the sinking triangle assembly 2 cooperates with the sinking triangle hole 5 and can slide horizontally in the sinking triangle hole 5. Since the sinking triangle holes 5 on the front guide plate 3 and the rear guide plate 4 are provided with an upper stroke section and a lower stroke section, when the front guide plate 3 and the rear guide plate 4 move left and right, the bearing 20 is pushed by the upper stroke section and the lower stroke section in the sinking triangle hole 5 to achieve up and down displacement, thereby driving the sinking triangle assembly 2 to achieve up and down movement.

[0029] Example 2

[0030] The same as Example 1, the difference is that the sinking triangle assembly 2 includes a left sinking triangle 21, a middle sinking triangle 22 and a right sinking triangle 23, the sinking triangle hole 5 includes a left sinking triangle hole 51, a middle sinking triangle hole 52 and a right sinking triangle hole 53, the left sinking triangle hole 51 and the right sinking triangle hole 53 are located on the left and right sides of the rear guide plate 4, the middle sinking triangle hole 52 is located on the front guide plate 3, the left sinking triangle 21, the middle sinking triangle 22 and the right sinking triangle 3 are all provided with bearings 20 and are respectively matched with the left sinking triangle hole 51, the middle sinking triangle hole 52 and the right sinking triangle hole 53 through the bearings 20.

[0032] The left settlement triangular hole 51 includes a left settlement upper stroke section 511, a left settlement transition stroke section 512 and a left settlement lower stroke section 513 which are arranged in sequence from left to right; the middle settlement triangular hole 52 includes a middle settlement upper stroke section 521, a middle settlement transition stroke section 522 and a middle settlement lower stroke section 523 which are arranged in sequence from left to right; the right settlement triangular hole 53 includes a right settlement lower stroke section 531, a right settlement transition stroke section 532 and a right settlement upper stroke section 533 which are arranged in sequence from left to right; the distance between the left settlement upper stroke section 511 and the right settlement lower stroke section 531 is greater than the distance between the left bearing 201 and the right bearing 203. Due to the setting of the above distances, four different settlement modes can be achieved; the front guide plate 3 is provided with a through hole which cooperates with the left settlement triangular hole 51 and the right settlement triangular hole 53. The through hole allows the bearings 20 of the left sinking triangle 21 and the right sinking triangle 23 to pass through the front guide plate 3, and then cooperate with the left sinking triangle hole 51 and the right sinking triangle hole 53 on the rear guide plate 4, so that the sinking of the left sinking triangle 21, the middle sinking triangle 22 and the right sinking triangle 23 can be controlled simultaneously in a limited space.

[0033] A guide plate limiting groove 14 is provided on the sedimentation bottom plate 1 , and the front guide plate 3 and the rear guide plate 4 are both located in the guide plate limiting groove 14 and move left and right.

[0034] A fixing plate 16 is further provided on the front side of the subsidence bottom plate 1. The fixing plate 16 is located below the subsidence triangle assembly 2.

The fixing seat 7 and the installation angle iron 8 form a chamber with the guide plate limit groove 14 to accommodate the front guide plate 3 and the rear guide plate 4. A motor plate 62 is also installed on the motor 6. The motor plate 62 is fixed to the fixing seat 7 and the motor mounting seat 10, thereby fixing the motor 6 on the sedimentation bottom plate 1.
