[0002] The cam is a component used in a knitting machine, and a needle groove is provided on its surface. When working, the needle needs to move in the needle track to achieve the knitting effect. For example, in the patent number "CN211471744U" and the patent name "A new type of high-precision wear-resistant knitting machine cam", when the base needs to be matched and connected, the embedded block B5 fixedly connected to one side of the base can be fixedly connected with the embedded hole B11 opened on one side of the base, so as to make a quick connection. When the cam needs to be connected, the embedded block A5 opened on one side of the cam can be matched and connected with the embedded hole A8 opened on one side of the cam, so that the cams are precisely connected, so that the base and the cam have a precise connection, which is easy to splice, thereby improving the precision, and the cam is fixed again through the hole. However, the above structure still has the following problems in actual use:

[0003] The triangle in the above structure is fixed by means of holes and screws. When the position of the triangle needs to be adjusted, the above structure needs to use a tool to loosen the screws before the overall position of the triangle can be adjusted, which makes the process time-consuming and inconvenient to adjust the triangle.

[0004] Therefore, we have proposed an adjustable knitting machine triangle that can well solve the above problems. Utility Model Content

[0005] The utility model aims to provide an adjustable knitting machine cam to solve the problem in the current market proposed by the above-mentioned background technology that the overall position of the cam can only be adjusted after the screws are loosened using tools, which makes the process time-consuming and inconvenient to adjust the cam.

[0006] To achieve the above object, the utility model provides the following technical solution: an adjustable knitting machine cam, comprising a cam member, a connecting slider is fixedly installed on the rear side of the cam member, and a sliding engagement connection structure is formed between the connecting slider and the cam seat;

[0007] It also includes: a push rod is provided on the front side of the triangle, and the push rod is slidably connected with the triangle and the connecting slider through a return spring, and the two ends of the return spring are respectively fixed to the push rod and the connecting slider;

[0008] The outer side surface of the rear end of the push rod is rotatably connected with a connecting rod, and the outer end of the connecting rod is rotatably connected with the clamping block.

[0009] Preferably, a sliding connection is formed between the connecting rod and the connecting slider, and the outer end of the connecting rod passes through the connecting slider and engages with the clamping hole.

[0013] Preferably, the heat dissipation layer is made of aluminum alloy, the inner wall of the heat dissipation layer is attached to the heat dissipation holes, and the outer ends of the heat dissipation holes are communicated with the through grooves.

[0014] Preferably, the through grooves are formed inside the triangular member, the triangular member is arranged in a "C" shape, both ends of the through grooves penetrate to the front side of the triangular member, and a row of through grooves are arranged at equal intervals.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The adjustable knitting machine triangle not only achieves the position adjustment of the triangular member, thus eliminating the need for other tools for adjustment, saving time and effort, and being convenient to use, but also has a wear-resistant effect, thereby reducing the wear degree of the triangular member, and avoiding heat residue on the inner wall of the needle running groove, thus avoiding the accumulation of heat affecting its use effect. The specific contents are as follows:

[0016] (1) By pressing the push rod, the push rod drives one end of the connecting rod rotatably connected thereto to move inward together, causing the connecting rod to pull the clamping block to move together, so that the outer end of the clamping block is separated from the clamping hole, enabling the connecting slider to slide up and down in the triangular seat, thereby achieving the position adjustment of the triangular member, eliminating the need for other tools for adjustment, saving time and effort, and being convenient to use;

[0017] (2) Moreover, a row of clamping holes are formed in the inner wall of the triangular seat at equal intervals from top to bottom, facilitating the fixing of the connecting slider at different heights;

[0018] (3) Further, through the elastic force of the return spring, the push rod and the connecting rod can be driven to reset together, causing the connecting rod to drive the clamping block to slide outward, so that the outer end of the clamping block engages with the clamping hole, thereby achieving the effect of fixing and limiting;

[0019] (4) When the needle moves in the needle groove, it will rub against the wear-resistant layer. The wear-resistant layer is made of aluminum oxide, which has a wear-resistant effect and reduces the wear degree of the triangular part;

[0020] (5) Furthermore, when the needle generates heat due to friction, the heat will be transported to the heat dissipation layer through the wear-resistant layer, and the heat dissipation layer will have the effect of heat conduction and heat dissipation. The heat can enter the through groove through the heat dissipation holes, and then be discharged through the heat dissipation holes and the through groove, thereby preventing heat from remaining on the inner wall of the needle groove, thereby preventing heat accumulation from affecting its use effect.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-Figure 7 , the utility model provides the following technical solutions:

[0031] Embodiment 1: In order to solve the problem in the prior art that the overall position of the triangle can be adjusted only after the screws are loosened using a tool, which makes the process time-consuming and inconvenient to adjust the triangle, the following scheme is disclosed, including a triangle member 1, a connecting slider 11 is fixedly installed on the rear side of the triangle member 1, and a sliding engagement connection structure is formed between the connecting slider 11 and the triangle seat 12; and further comprising: a push rod 7 is provided on the front side of the triangle member 1, a connecting rod 9 is rotatably connected to the outer side of the rear end of the push rod 7, and the outer end of the connecting rod 9 is rotatably connected to the clamping block 10, a sliding connection is formed between the connecting rod 9 and the connecting slider 11, and the outer end of the connecting rod 9 passes through the connecting slider 11 and forms an engagement connection with the clamping hole 13;

[0032] By pressing the push rod 7, the push rod 7 slides inwardly, and the return spring 8 is in a compressed state. When the push rod 7 slides inwardly, it also drives one end of the connecting rod 9 connected thereto to move inwardly, and the other end of the connecting rod 9 is connected to the block 10 through the rotation connection, so that the connecting rod 9 pulls the block 10 to move together, so that the block 10 slides toward the connecting slider 11, so that the outer end of the block 10 is separated from the clamping hole 13, and the limit of the connecting slider 11 is released. At this time, the connecting slider 11 can slide up and down in the triangular seat 12, and the inner wall of the triangular seat 12 is evenly spaced from top to bottom. A row of clamping holes 13 are provided, which is convenient for fixing the connecting slider 11 at different heights. The fixed installation between the triangular member 1 and the connecting slider 11 can achieve the position adjustment of the triangular member 1, so that there is no need to use other tools for adjustment, which saves time and effort and is convenient to use.

[0033] Embodiment 2: Different from Embodiment 1, this embodiment facilitates the limiting and fixing of the connecting slider 11. For details, refer to Figure 4-Figure 6 , and the push rod 7 is slidably connected with the triangular member 1 and the connecting slider 11 through the return spring 8, and the two ends of the return spring 8 are respectively fixed to the push rod 7 and the connecting slider 11, and the clamping hole 13 is opened on the inner wall of the triangular seat 12, and the triangular seat 12 is vertically opened in a row at equal intervals;

[0034] When it is adjusted to a suitable position, the push rod 7 is released, and the elastic force of the return spring 8 drives the push rod 7 to slide outward, so that the push rod 7 drives one end of the connecting rod 9 to move outward together, and the connecting rod 9 drives the block 10 to slide outward through the rotation connection structure between the connecting rod 9 and the block 10, and the sliding connection between the block 10 and the connecting slider 11, so that the outer end of the block 10 is engaged with the clamping hole 13, thereby achieving the effect of fixed limit;

[0035] Embodiment 3: Different from Embodiment 2, this embodiment can achieve the effect of wear resistance and heat dissipation. For specific reference, see Figure 1-Figure 4 , a needle running groove 2 is formed on the front side of the triangular part 1, a heat dissipation layer 3 is attached to the inner wall of the needle running groove 2, the outer wall of the heat dissipation layer 3 is attached to the wear-resistant layer 4, the wear-resistant layer 4 is made of alumina material, and is bonded to the heat dissipation layer 3 through an adhesive made of mixed polyester resin. The heat dissipation layer 3 is made of aluminum alloy material, and the inner wall of the heat dissipation layer 3 is attached to the heat dissipation holes 5, and the outer ends of the heat dissipation holes 5 are communicated with the through grooves 6. The through grooves 6 are formed inside the triangular part 1, and the triangular part 1 is arranged in a "C" shape. The two ends of the through groove 6 penetrate to the front side of the triangular part 1, and a row of through grooves 6 are equally spaced.

[0036] Moreover, the heat dissipation layer 3 is attached to the inner wall of the needle running groove 2, and the wear-resistant layer 4 is attached to the outer side of the heat dissipation layer 3. The wear-resistant layer 4 is made of alumina material and is bonded to the heat dissipation layer 3 through an adhesive made of mixed polyester resin, thereby achieving the effect of wear resistance. When the needle runs in the needle running groove 2, it will rub against the wear-resistant layer 4. Through the setting of the wear-resistant layer 4, the wear resistance of the triangular part 1 is improved. It can not only protect the triangular part 1 and extend its service life, but also the inner wall of the wear-resistant layer 4 is attached to the heat dissipation layer 3. The heat dissipation layer 3 is made of aluminum alloy material. Therefore, when heat is generated by the friction of the needle running, the heat will be transmitted to the heat dissipation layer 3 through the wear-resistant layer 4. The heat dissipation layer 3 plays a role in heat conduction and dissipation. The heat dissipation layer 3 is communicated with the through groove 6 through the heat dissipation holes 5. Therefore, the heat can enter the through groove 6 through the heat dissipation holes 5 and then be discharged through the heat dissipation holes 5 and the through groove 6, thereby avoiding the residual heat on the inner wall of the needle running groove 2 and avoiding the accumulation of heat affecting its use effect.
