[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] Reference Figures 1-5 As shown, this embodiment provides a specific implementation of a four-speed connecting rod frame, including a fixed plate 10, a support plate 20, and a connecting rod 30. There are several support plates 20, one end of which is parallel and perpendicular to the fixed plate 10. The other ends of the several support plates 20 are connected and fixed together by the connecting rod 30 to form a receiving cavity 40 between adjacent support plates 20. The receiving cavity 40 is used to receive the crankshaft connecting rod transmission mechanism.

[0023] When there are 5 support plates 20 and 4 accommodating cavities 40, four sets of crankshaft connecting rod transmission mechanisms, i.e., four-speed connecting rod frames, can be installed. Compared with three-speed connecting rod frames, the installation of four sets of crankshaft connecting rod transmission mechanisms on the four-speed connecting rod frames and the installation on the warp knitting machine does not hinder the structure of the traditional warp knitting machine. Adding one or more sets of crankshaft connecting rod transmission mechanisms solves the problem of unreasonable arrangement leading to slow machine operation speed, reduces the load on each component by half, extends service life, reduces noise, increases speed by 30%, and makes operation more stable.

[0024] In other embodiments, the number of support plates 20 is 9, and the number of accommodating cavities 40 is 6, which can install 6 sets of crankshaft connecting rod transmission mechanisms to form a six-speed connecting rod frame. This also solves the problem of unstable transmission in traditional three-speed connecting rod frames, improves transmission efficiency, and thus improves production efficiency.

[0025] The support plate 20 further includes a first mounting hole 201 and a first cover plate 202. The first end face of the support plate 20 has a plurality of first mounting holes 201. The first cover plate 202 is detachably and fixedly connected to the first mounting holes 201 at both ends by screws, so as to fix the rotating shaft of the crankshaft connecting rod transmission mechanism in the first mounting holes 201.

[0026] The support plate 20 further includes a second mounting hole 203 and a second cover plate 204. Each support plate 20 has a second mounting hole 203 on its first end face. The two ends of the second cover plate 204 are detachably and fixedly connected to the second mounting hole 203 by screws, so as to fix the rotating shaft of the crankshaft connecting rod transmission mechanism in the second mounting hole 203.

[0027] In this embodiment, the crankshaft connecting rod transmission mechanism is detachably and fixedly connected to the first mounting hole 201 and the second mounting hole 203 by screws locking the first cover plate 202 and the second cover plate 204 to the support plates 20 on both sides of the first mounting hole 201 and the second mounting hole 203, thereby realizing the quick installation and disassembly of the crankshaft connecting rod transmission mechanism, which is easy to implement.

[0028] The first cover plate 202 and the second cover plate 204 are also provided with oil injection holes 221.

[0029] Furthermore, the center of the oil injection hole 221 is on the same axis as the center of the first mounting hole 201 or the second mounting hole 203.

[0030] After the crankshaft connecting rod transmission mechanism is installed on the fourth-speed connecting rod holder, lubricating oil can be injected into the connection between the crankshaft connecting rod transmission mechanism and the fourth-speed connecting rod holder through the oil injection hole 221 to ensure smooth rotation of the crankshaft connecting rod transmission mechanism.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
