Description

Technical Field

[0001] This utility model belongs to the field of telescopic joint technology, and in particular relates to a mechanism for adjusting the gap between the inner and outer arms of a telescopic joint. Background Technology

[0002] In industrial equipment, a telescopic joint is a component used to connect two parts and allow them to move relative to each other. It functions similarly to a human joint, enabling the equipment or structure to extend and retract freely during actual use, thereby meeting corresponding operational requirements.

[0003] Existing telescopic joints include an outer arm and an inner arm. The inner arm extends and retracts relative to the outer arm. Typically, a guide block is installed on the outer arm to guide the extension and retraction of the inner arm. However, the guide block suffers from severe wear over long-term use. When the wear of the guide block becomes excessive, it loses its guiding function for the inner arm, reducing the guiding accuracy. In this case, the guide block needs to be replaced, which is time-consuming and labor-intensive, leading to increased costs. Therefore, a mechanism for adjusting the gap between the outer and inner arms of a telescopic joint is provided. By changing the gap between the outer and inner arms, the service life of the guide block is extended. Utility Model Content

[0027] This embodiment provides a mechanism for adjusting the gap between the inner and outer arms of a telescopic joint. This mechanism changes the gap between the outer arm 11 and the inner arm 12 by changing the feed amount of the adjusting block 20 along its length direction within the outer arm 11. Therefore, when the guide block 122 experiences excessive wear, the adjusting block 20 can be adjusted to allow the guide block 122 to re-fit against the outer surface of the inner arm 12, thus satisfying the guiding effect on the inner arm 12. Therefore, this embodiment can further extend the service life of the guide block 122 and reduce the replacement cost of the guide block 122.

[0028] Combination Figures 1 to 6 As shown, the mechanism for adjusting the gap between the inner and outer arms of the telescopic joint in this embodiment includes a joint body 10, a slot frame 50, a guide block 122, and an adjusting block 20. The joint body 10 includes an outer arm 11 and an inner arm 12. The inner arm 12 is sleeved inside the outer arm 11 and moves along the length of the outer arm 11. A guide block 122 is provided between the inner arm 12 and the outer arm 11. The guide block 122 is installed in the slot plate 51 to guide the movement of the inner arm 12. During the movement of the inner arm 12, the guide block 122 will be continuously subjected to friction. Therefore, under long-term use, the guide block 122 will experience excessive wear, affecting the guiding effect. The adjusting block 20 can adjust the gap between the outer arm 11 and the inner arm 12, so that the guide block 122 can once again fit against the outer surface of the inner arm 12, thereby allowing the worn guide block 122 to still provide good guidance for the inner arm 12.

[0029] In this embodiment, an actuator 30 is provided inside the outer joint arm 11. The actuator 30 is connected to the inner joint arm 12 to drive the inner joint arm 12 to move relative to the outer joint arm 11. In this embodiment, the actuator 30 is a cylinder, hydraulic cylinder or electric cylinder. The actuator 30 drives the inner joint arm 12 to move relative to the outer joint arm 11, thereby achieving the purpose of extension and retraction of the telescopic joint.

[0030] Combination Figures 1 to 3 As shown, in this embodiment, the adjusting block 20 is disposed within the slot plate 51, and the slot frame 50 is disposed at the end opening of the outer joint arm 11. The feed amount of the adjusting block 20 within the outer joint arm 11 along its length direction is adjustable. When the feed amount of the adjusting block 20 within the outer joint arm 11 changes, the gap between the outer joint arm 11 and the inner joint arm 12 changes. When the feed amount increases, the gap between the outer joint arm 11 and the inner joint arm 12 increases; when the feed amount decreases, the gap between the outer joint arm 11 and the inner joint arm 12 decreases. Therefore, when the guide block 122 experiences excessive wear, the gap between the outer joint arm 11 and the inner joint arm 12 will decrease due to the thinning of the guide block 122. Increasing the feed amount of the adjusting block 20 causes the guide block 122 to move towards the inner joint arm 12 along the thickness direction of the slot plate 51, and to re-fit against the outer surface of the inner joint arm 12, thereby ensuring that the worn guide block 122 can still provide good guidance for the inner joint arm 12.

[0031] In this embodiment, there are several guide blocks 122, which are spaced apart around the outer arm 11 of the joint. The guide blocks 122, which are set at multiple positions, can stably guide the inner arm 12 of the joint and improve the guiding effect.

[0032] Combination Figures 3 to 5As shown, the guide block 122 in this embodiment is provided with a first inclined surface 1221, and the adjusting block 20 is provided with a second inclined surface 21. When the adjusting bolt 40 is adjusted to a certain position, the first inclined surface 1221 and the second inclined surface 21 fit together, thereby satisfying the guiding operation of the guide block 122 on the inner arm 12 of the joint.

[0033] In this embodiment, the adjusting block 20 is disposed in the slot plate 51, and the slot frame 50 is installed at the end opening of the joint outer arm 11 by the fixing bolt 60. The adjusting bolt 40 drives the adjusting block 20 to change the feed amount of the adjusting block 20 along its length direction in the joint outer arm 11. By rotating the adjusting bolt 40, the feed amount of the adjusting block 20 along its length direction in the joint outer arm 11 is changed, thereby changing the gap between the joint outer arm 11 and the joint inner arm 12.

[0034] In this embodiment, the mechanism for adjusting the gap between the inner and outer arms of the telescopic joint is used in practical applications. Under the drive of the driver 30, the inner arm 12 moves along the length direction of the outer arm 11. The guide block 122 guides the movement of the inner arm 12. The guide block 122 will wear out after long-term use. When the wear is too great, the guide block 122 can no longer guide the inner arm 12. At this time, by increasing the feed amount of the adjusting block 20 in the outer arm 11, the guide block 122 moves towards the inner arm 12 along the thickness direction of the guide plate, so that the guide block 122 is in contact with the outer surface of the inner arm 12 again. Thus, the worn guide block 122 can still provide good guidance for the inner arm 12, thereby effectively avoiding the need to replace the guide block 122 and reducing the replacement cost of the guide block 122.
