Description

Technical Field

[0001] The utility model belongs to the field of flat knitting machines, and in particular relates to a Uss seat with a bottom that prevents yarn from being clamped. Background Art

[0002] The Wusi seat is a part installed on the sky bar of the knitting machine. It is driven by the machine head and slides on the sky bar to select yarns of different colors or specifications. The yarn is fed to the knitting needles through the yarn mouth fixing hole and yarn mouth on the Wusi seat.

[0003] Generally, the Uzi seat is fixed on the mast by clamping the mast up and down with the upper edge of the Uzi seat body and the friction plate. Since the Uzi seat often slides on the mast during operation, the friction plate wears quickly, and the height of the friction plate needs to be adjusted frequently to compensate for the increased distance between the friction plate and the upper edge of the Uzi seat body caused by the wear. The existing Uzi seat friction plate is adjusted upward by pushing the bolt at the bottom of the Uzi seat upward.

[0004] However, the bolt heads at the bottom of the Uzi seat for adjusting the friction plate are generally exposed outside the bottom surface of the Uzi seat. When the Uzi seat is feeding yarn, the yarn can easily run into the gap between the bolt head and the bottom surface of the Uzi seat, and the yarn can easily be clamped by the above two, which will affect the weaving work. Utility Model Content

[0005] Therefore, the technical problem to be solved by the present invention is that the bolt at the bottom of the existing Uzzi seat for adjusting the friction plate has its head exposed outside the bottom surface of the Uzzi seat, which easily causes the yarn to be clamped by the bolt head and the bottom surface of the Uzzi seat.

[0006] The top of the support frame is connected with the support rod of the lifting link, and the bottom of the support frame is connected with the support rod of the lifting link.

[0007] Preferably, the shape of the enclosure ring can be one of circular, square or rectangular.

[0008] Preferably, the through hole is a stepped hole, comprising a first step and a second step from top to bottom, and the inner diameter of the first step is smaller than the inner diameter of the second step.

[0009] Preferably, two coil springs are further included, two sleeves are fixed to the bottom of the friction plate, one end of each coil spring is tightly sleeved and fixed on one of the sleeves, and the other end of the coil spring is fixed to the top of the connecting plate.

[0010] Preferably, a locking nut is fixed inside the first step, and the bolt can be inserted into the locking nut and threadedly connected to the locking nut.

[0011] Preferably, a nylon anti-slip ring is further provided on the inner wall surface of the anti-loosening nut.

[0012] The technical solution of this utility model has the following beneficial effects:

[0013] The utility model provides a retaining ring on the bottom surface of the connecting plate that is concentric with the through hole for inserting the bolt. The shape of the retaining ring is consistent with the shape of the bolt head, and the inner diameter of the retaining ring is consistent with the diameter of the bolt head. When the Us seat is clamped on the sky rod, the bolt head is flush with the bottom of the retaining ring, and the bolt head can be hidden inside the retaining ring, which can effectively prevent the yarn from being clamped between the bolt head and the bottom of the Us seat when the Us seat is working, thereby avoiding the occurrence of the situation where the yarn is clamped and affects the weaving work.

[0023] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0026] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] The utility model provides an Us seat with a bottom anti-yarn pinching function, comprising a friction plate 1, an Us seat main body 2, a clamping plate 3 and a connecting plate 4, the clamping plate 3 is parallel to the Us seat main body 2, the connecting plate 4 is located at the bottom of the clamping plate 3 and the Us seat main body 2, the connecting plate 4, the clamping plate 3 and the Us seat main body 2 are integrally formed and connected together, the clamping plate 3 is located at the front side of the Us seat main body 2 near the bottom, and there is a spacing between the clamping plate 3 and the Us seat main body 2 to form an accommodating space 5, part of the friction plate 1 can be accommodated in the accommodating space 5, the connecting plate 4 is provided with two vertical axial through holes 41, each of the through holes 41 can be penetrated by a bolt 7, the bolt 7 and the through hole 41 cooperate with each other to adjust the position in the up and down directions, and when the tail of the bolt 7 presses against the bottom of the friction plate 1, the friction plate 1 can be moved upward.

[0028] The connecting plate 4 is provided with a retaining ring 42 concentric with the through hole 41. The shape of the retaining ring 42 is consistent with the shape of the head of the bolt 7, and the inner diameter of the retaining ring 42 is consistent with the diameter of the head of the bolt 7. When the Uzi seat is clamped to the sky pole, the head of the bolt 7 is flush with the bottom of the retaining ring 42. When the head of the bolt 7 is hidden inside the retaining ring 43, it can effectively prevent the yarn from being clamped between the head of the bolt 7 and the bottom of the Uzi seat when the Uzi seat is working.

[0029] The shape of the enclosure ring 42 can be circular, square or rectangular.

[0030] When the Us seat needs to be installed on the sky pole, the sky pole needs to be passed through between the upper edge of the Us seat body 2 and the top of the friction plate 1. Since the bottom of the friction plate 1 and the top of the connecting plate 4 are connected by a coil spring 8, the friction plate 1 can adaptively adjust the up and down positions according to the height value of the sky pole, and the bottom of the friction plate 1 can abut the tail of the bolt 7. The bolt 7 is adjusted upward as much as possible in the through hole 41 and pressed against the bottom of the friction plate 1, so that the top of the friction plate 1 is pressed against the bottom of the sky pole, and the upper edge of the Us seat body 2 is pressed against the top of the sky pole, and finally the Us seat is installed on the sky pole.

[0031] When the Wusi seat slides on the sky pole for a long time, the friction plate 1 often rubs against the sky pole and wears out. This will cause the gap between the upper edge of the Wusi seat body 2 and the friction plate 1 to increase, affecting the installation balance of the Wusi seat on the sky pole. Therefore, at this time, the height of the bolt 7 can be adjusted upward, thereby adjusting the position of the friction plate 1 upward to compensate for the increased gap caused by the wear of the friction plate 1.

[0032] The through hole 41 is configured as a stepped hole, including a first step 411 and a second step 412 from top to bottom. The inner diameter of the first step 411 is smaller than that of the second step 412. The diameter of the head of the bolt 7 is equal to the inner diameter of the second step 412. When the Uss seat is clamped to the sky pole, the head of the bolt 7 is located inside the second step 412, and there is essentially no gap between the head of the bolt 7 and the head of the second step 412, preventing yarn from entering. The configuration of the first step 411 and the second step 412 can impose an upper limit on the upward travel of the bolt 7, preventing the coil spring 8 from deforming to its limit.

[0033] In order to facilitate the use of bolts 7 to connect the spring and the friction plate 1, the utility model has two sleeves 11 fixed to the bottom of the friction plate 1. One end of each coil spring 8 is tightly sleeved and fixed on a sleeve 11, and the other end of the coil spring 8 is fixed to the top of the connecting plate 4.

[0034] To prevent vibration caused by the sliding of the gusset seat from loosening the bolt 7 directly threaded into the through hole 41, a lock nut 6 is fixed inside the first step 411. The bolt 7 can be inserted into the lock nut 6 and threadedly connected to the lock nut 6. The lock nut 6 is a prior art product, and its working principle will not be explained in detail here. The lock nut 6 prevents loosening caused by vibration and ensures that the bolt 7 is firmly fixed in the through hole 41.

[0035] A nylon anti-slip ring 61 is also provided on the inner wall of the anti-loosening nut 6. This design allows the nylon anti-slip ring 61 to be squeezed and generate a reaction force during the threaded tightening process (threaded tightening of the bolt 7 and the anti-loosening nut 6), thereby increasing the friction between the inner and outer threads and further preventing the bolt 7 from loosening.

[0036] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
