Description

Technical Field

[0001] This application relates to the technical field of electronic jacquard machines, and in particular to a pull rod structure that can be filled with lubricant. Background Art

[0002] As a connecting mechanism for connecting the frame plate and the broach, the pull rod structure needs to move up and down frequently and swing slightly left and right when the frame plate and the broach are running. In order to extend the service life of the bearing and shorten it, lubricating grease is applied to the pull rod mechanism during assembly. However, the pull rod structure has no oil storage mechanism and the space is narrow, and the structure needs to be disassembled to refill the lubricant again, resulting in high maintenance difficulty. Utility Model Content

[0003] Aiming at the deficiencies of the prior art, one of the purposes of this application is to provide a pull rod structure that can be filled with lubricant, which has the advantages of directly filling the sliding bearing with lubricant without disassembling the pull rod structure, storing a certain amount of lubricant inside to reduce the maintenance frequency, and making the maintenance of the structure more convenient.

[0004] The above object of this application is achieved through the following technical solutions:

[0005] A pull rod structure that can be filled with lubricant includes a pull rod, a bearing and a feeding member. The feeding member and the bearing are installed on the pull rod. A cavity is formed between the pull rod and the bearing for storing a medium. The feeding member is communicated with the cavity, and the feeding member supplies the medium to enter the cavity.

[0006] By adopting the above technical solution, the medium enters the cavity formed by the pull rod and the bearing through the feeding member, so that the medium is stored in the cavity, making it unnecessary to disassemble the pull rod structure when filling the medium, and storing a certain amount of medium in the cavity can reduce the maintenance frequency, and further making the maintenance of the structure more convenient.

[0007] In a preferred example of this application, it can be further configured that: the pull rod includes a through hole and a receiving cavity. One end of the through hole is communicated with the feeding member, and the other end is communicated with the cavity. The through hole supplies the medium to enter the cavity, and the receiving cavity is used for receiving the bearing.

[0008] By adopting the above technical solution, one end of the through hole is communicated with the feeding member, and the other end is communicated with the cavity, achieving the purpose of communicating the feeding member and the cavity.

[0009] In a preferred example of this application, it can be further configured that: it further includes a connecting sleeve. The bearings are installed at both ends of the connecting sleeve, and the connecting sleeve is used to cooperate with the bearing and the pull rod to form a cavity.

[0010] By adopting the above technical solution, the connecting sleeve cooperates with the bearing and the pull rod to form a cavity, making the airtightness of the cavity better.

[0011] By adopting the above technical solution, the medium can be more fully driven from the through hole into the cavity.

[0012] In a preferred example of the present application, it can be further configured that the included angle between the axis of the through hole and the center line of the pull rod is 30° to 45°.

[0013] By adopting the above technical solution, when the medium flows into the cavity, the guiding effect of the through hole on the medium is better.

[0014] In a preferred example of the present application, it can be further configured that the pull rod is provided with a groove, and the groove is used to facilitate the taking of the pull rod.

[0015] By adopting the above technical solution, the groove makes it convenient to take the pull rod, and thus it is more convenient to install the pull rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following further describes the present application in detail with reference to the drawings.

[0020] Referring to Figure 1 and Figure 2 , a pull rod structure capable of filling lubricant disclosed in the present application includes a pull rod 1, a bearing 2, a feeding member 3 and a connecting sleeve 5. The pull rod 1 includes a through hole 11 and a receiving cavity 12. The through hole 11 and the receiving cavity 12 are provided at both ends of the pull rod 1. One end of the through hole 11 is connected to the feeding member 3, and the other end is connected to the cavity 4. The feeding member 3 allows the medium to enter the through hole 11, and the through hole 11 allows the medium to enter the cavity 4. The receiving cavity 12 is used to accommodate the bearing 2, and the bearing 2 is installed at both ends of the connecting sleeve 5. A cavity 4 is formed between the pull rod 1 and the bearing 2. The connecting sleeve 5 is used to cooperate with the bearing 2 and the pull rod 1 to form the cavity 4. The cavity 4 is used to store the medium. The feeding member 3 is connected to the cavity 4, and the feeding member 3 is installed on the pull rod 1 to allow the medium to enter the cavity 4. In this embodiment, the feeding member 3 can adopt a grease nipple, and the medium can adopt grease.

[0021] The included angle between the axis of the through hole 11 and the center line of the pull rod 1 is 30° to 45°. In this embodiment, the included angle between the axis of the through hole 11 and the center line of the pull rod 1 can adopt 30°, 35°, 40° or 45°.

[0022] During installation, the bearing 2 is installed at both ends of the connecting sleeve 5, and then the connecting sleeve 5 and the bearing 2 are installed in the receiving cavity 12 of the pull rod 1, so that a cavity 4 is formed between the bearing 2, the connecting sleeve 5 and the pull rod 1. The feeding part 3 is installed on the pull rod 1, and the pull rod 1 is connected to other equipment through the mounting hole 6 of the connecting sleeve 5. When maintaining the pull rod 1 and the bearing 2, the medium is injected from the feeding part 3 through the through hole 11, so that the medium enters the cavity 4 from the through hole 11, and the medium contacts the bearing 2, thereby maintaining the bearing 2 and the pull rod 1.

[0023] The implementation principle of this embodiment is as follows: By using the cooperation of the bearing 2, the connecting sleeve 5 and the pull rod 1, a cavity 4 for storing the medium is formed inside the pull rod 1, and the cavity 4 is communicated with the feeding part 3 on the pull rod 1, so that the medium can contact the bearing 2 and be stored in the cavity 4. Therefore, when injecting the medium, it is not necessary to disassemble the structure of the pull rod 1 and the maintenance frequency is reduced, making the maintenance of the structure more convenient.

[0024] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application shall be covered within the protection scope of this application.
