Technical Field

[0001] The utility model relates to the technical field of industrial machines, in particular to an indoor robot joint. Background Art

[0002] The progress of modern industry is inseparable from the development of hardware facilities, among which indoor robots play an extremely critical role.

[0003] The structures used in the joints of existing indoor robots are mostly assembled. Although they are flexible and diverse, they lack sufficient structural strength, which often leads to breakage accidents in actual applications. In addition, the fixed joint structure makes it easy for gaps and holes to exist in the interface, making it impossible to ensure the sealing of the connection, and even causing structural wear due to severe friction between the joints. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An indoor robot joint comprises an end sleeve and a front end head of an integrated structure, wherein the end sleeve is provided with eight through holes, and an embedding groove and a limiting ring groove are provided at the end position of the end sleeve, and the end sleeve is provided with a sealing mechanism for increasing the sealing of the joint through the embedding groove and the limiting ring groove.

[0007] Preferably, the terminal sleeve is communicated with the front end head.

[0008] Preferably, the eight through holes are circumferentially and equidistantly distributed on the end sleeve, and the embedding groove is concentrically arranged with the limiting ring groove.

[0009] Preferably, the closing mechanism includes a limit plate integrally arranged on the limit ring groove, and a limit hole is provided in the limit plate, a sealing gasket extending into the limit ring groove is mounted in the embedded groove, a limit ring is movably mounted on the end sleeve, and an extension rod corresponding to the limit plate is integrally connected to the limit ring, a receiving groove is provided in the extension rod, and a limit pull bolt corresponding to the limit hole is installed on the pin shaft in the receiving groove, and a limit torsion spring fixedly connected to the receiving groove is fixedly mounted on the limit pull bolt.

[0010] Preferably, the limiting circular ring is slidably mounted on the end sleeve, and the extension rods and the limiting pull bolts are circumferentially equidistantly arranged in a one-to-one correspondence.

[0011] Preferably, the extension rod and the limiting pull bolt both slide through the limiting hole.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The utility model provides an integrated structure of the end sleeve and the front end head, and the two are connected as one, thereby ensuring the overall structural strength of the robot joint.

[0014] 2. The utility model sets a sealing gasket at the position of the end sleeve, and then sets an extension rod using a limiting ring that can be slidably adjusted on the end sleeve, so that the limiting pull bolt in the extension rod can limit and fix the sealing gasket extending to the limiting ring groove, which can improve the connection sealing of the end sleeve interface.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 An indoor robot joint includes an end sleeve 1 and a front end head 2 of an integrated structure. It should be noted that the robot joint is arranged in one piece to ensure structural strength. Eight through holes 3 are provided on the end sleeve 1, and an embedding groove 4 and a limiting ring groove 5 are provided at the end position of the end sleeve 1. A sealing gasket 8 with a light and soft structure is mounted on the embedding groove 4 to enhance the sealing performance.

[0022] The end sleeve 1 is provided with a closing mechanism for increasing the sealing of the joint through the embedded groove 4 and the limiting ring groove 5. The closing mechanism includes a limiting plate 6 integrally arranged on the limiting ring groove 5, and a limiting hole 7 is provided in the limiting plate 6. A sealing gasket 8 extending to the limiting ring groove 5 is sleeved in the embedded groove 4. It should be noted that the sealing gasket 8 adopts a double-layer structure and is sleeved on the interface part of the end sleeve 1 to enhance the sealing. A limiting circular ring 9 is movably sleeved on the end sleeve 1, and an extension rod corresponding to the limiting plate 6 is integrally connected to the limiting circular ring 9. 10. A receiving groove 11 is provided in the extension rod 10, and a limiting pull bolt 12 corresponding to the limiting hole 7 is installed on the pin shaft in the receiving groove 11. It should be noted that the limiting pull bolt 12 can adjust the angle in the receiving groove 11 so as to realize telescopic adjustment in the limiting plate 6. A limiting torsion spring 13 fixedly connected to the receiving groove 11 is fixedly sleeved on the limiting pull bolt 12. Under the elastic force of the limiting torsion spring 13, the extension rod 10 and the limiting pull bolt 12 are maintained at 90°, thereby limiting and fixing the sealing gasket 8 in the limiting ring groove 5.

[0023] Please refer to the instruction manual for details Figure 1 With attached Figure 3 , the end sleeve 1 is connected to the front end head 2.

[0024] Eight through holes 3 are equidistantly distributed on the end sleeve 1 in the circumferential direction, and the embedding groove 4 is concentrically arranged with the limiting ring groove 5 .

[0025] The limiting ring 9 is slidably mounted on the end sleeve 1, and the extension rod 10 and the limiting pull bolt 12 are circumferentially equidistantly arranged in a one-to-one correspondence. It should be noted that the extension rod 10 and the limiting pull bolt 12 are driven to extend and retract horizontally so as to limit and fix the sealing gasket 8 in the limiting ring groove 5.

[0026] The extension rod 10 and the limiting pull bolt 12 both slide through the limiting hole 7 .

[0027] It should be noted that the specific model and specification of the sealing gasket 8 needs to be selected and determined according to the actual specifications of the device, and the specific selection and calculation method adopts the existing technology in the field, so it is not repeated here.

[0028] The functional principle of the utility model can be explained through the following operation modes:

[0029] Put the sealing gasket 8 on the embedding groove 4 so that the sealing gasket 8 extends into the limiting ring groove 5;

[0030] The limiting ring 9 is moved on the end sleeve 1, so that the limiting ring 9 drives the extension rod 10 to move horizontally, so that the extension rod 10 drives the limiting pull bolt 12 received in the receiving groove 11 to pass through the limiting hole 7;

[0031] Under the elastic action of the limiting torsion spring 13 , the limiting pull bolt 12 is opened, so that the limiting pull bolt 12 and the extension rod 10 are at a 90° angle, and the sealing gasket 8 located in the limiting ring groove 5 is limited and fixed by the limiting pull bolt 12 .
