Detailed implementation mode

[0024] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0026] Please refer to Figures 1 to 4 , a rotatable full-automatic piston rod end joint provided by an embodiment of the present utility model, the rotatable full-automatic piston rod end joint includes: an adapter block 2 provided at the end of the piston rod body 1, and a connecting head 4 movably connected to the outside of the adapter block 2.

[0027] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 and Figure 3 , a main universal housing 3 fixedly connected to the side of the adapter block 2 close to the connecting head 4, a main universal ball 31 rotatably connected to the inside of the main universal housing 3, 1 / 3 of the main universal ball 31 is exposed outside the main universal housing 3, a connecting column 32 is installed at the exposed part of the main universal ball 31, and the end of the connecting column 32 is connected to the outer wall of the connecting head 4.

[0028] It should be noted that: by using the main universal housing 3 and the main universal ball 31 to install the connecting head 4, during the later use process, when installing and connecting this device to an external device, hold the connecting head 4, and make it drive the main universal ball 31 to rotate inside the main universal housing 3 through the connecting column 32, then the rotation of the connecting head 4 can be realized. Then, according to the need of the inclination angle of the connecting component, the connecting head 4 can be toggled in the corresponding direction, and further drive the main universal ball 31 to tilt in the main universal housing 3. Thus, the multi-angle adjustment of the connecting head 4 can be realized, enabling the staff to more conveniently connect this device to external components, and improving the flexibility of the later installation of this device.

[0029] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 and Figure 4A reinforcing rod 5 is arranged between the connecting head 4 and the connecting plate 21 to increase the connection strength between the main universal shell 3 and the main universal ball 31. Both ends of the reinforcing rod 5 are provided with fixedly connected auxiliary universal balls 51. The outside of the auxiliary universal ball 51 is provided with a rollingly connected auxiliary universal shell 52. The reinforcing rod 5 is a telescopic rod. A fixedly connected connecting ring 7 is arranged on the outside of the connecting head 4, and a rotating ring 8 is arranged on the outside of the adapter block 2. The outer walls of the connecting ring 7 and the rotating ring 8 are fixedly connected to the ends of the auxiliary universal shell 52, and 1 / 3 of the auxiliary universal ball 51 is exposed outside the auxiliary universal shell 52.

[0030] It should be noted that: by installing the reinforcing rod 5 outside the main universal housing 3 and the universal ball, the connection part of the connector 4 can be auxiliary strengthened, the support strength of the active part of the connecting end can be improved, and the phenomenon of damage to the connection part of the connector 4 during the later use can be reduced;

[0031] Since the reinforcing rod 5 is a telescopic rod structure, and the auxiliary universal balls 51 and the auxiliary universal shells 52 are arranged at both ends, when the main universal ball 31 is tilted and moved during the later application process, the reinforcing rod 5 can be driven to move synchronously through the connecting head 4, and the telescopic reinforcing rod 5 can be telescopically adjusted by rotating the auxiliary universal ball 51 at the end inside the auxiliary universal shell 52, thereby preventing the reinforcing rod 5 from hindering the later angle adjustment of the connecting head 4, making the angle adjustment of the connecting head 4 more flexible, and improving the supporting strength of the connection of the connecting head 4.

[0032] In the embodiments of the present invention, please refer to Figure 2 and Figure 4 A protective cover 6 is arranged between the connecting ring 7 and the rotating ring 8. The protective cover 6 is sleeved on the outside of the reinforcing rod 5, and the protective cover 6 is a flexible structure.

[0033] It should be noted that the flexible protective cover 6 located outside the reinforcing rod 5 and other components can cover and seal the movable part of the connecting end, thereby preventing dust in the air from entering the movable main universal shell 3 and the main universal ball 31 during subsequent use and affecting their rotation, thereby ensuring the flexible rotation of the connecting head 4 in the later stage.

[0034] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A fixedly connected limit ring 81 is provided on the outside of the adapter block 2, and the inner wall of the limit ring 81 abuts against and is rotatably connected to the outer wall of the rotating ring 8. A fixedly connected connecting plate 21 is provided on the end of the adapter block 2 away from the connecting head 4, and the connecting plate 21 is fixedly connected to the end of the piston rod body 1 by bolts.

[0035] It should be noted that: by using the bolt connecting plate 21 to connect with the piston rod body 1, during the subsequent use process, when the connecting head 4 is damaged, it is convenient for the staff to separate the adapter block 2 from the piston rod body 1, and then it is more convenient for the staff to repair and replace the connecting head 4. And through the setting of the limiting ring 81, the limiting ring 81 can realize the limitation of the rotating ring 8, and further prevent the rotating ring 8 from randomly displacing during the use process. Therefore, the rotating ring 8 can stably rotate with a number of reinforcing rods 5 later, connect the number of reinforcing rods 5 into a whole, and increase the connection stability between the connecting head 4 and the adapter block 2.

[0036] The working principle of the rotatable full-automatic piston rod end joint provided by the present utility model is as follows:

[0037] During the subsequent use of this device, first, the cylinder barrel in the piston rod body 1 can be fixed at the required position according to needs;

[0038] After the cylinder barrel of the piston rod body 1 is fixed, hold the connecting head 4 according to the angle of the external connecting component to be connected, and make it drive the main universal ball 31 to rotate inside the main universal housing 3 through the connecting column 32, so as to realize the rotation of the connecting head 4. Then, according to the need of the inclination angle of the connecting component, the connecting head 4 can be toggled in the corresponding direction, and further drive the main universal ball 31 to tilt in the main universal housing 3. Thus, the multi-angle adjustment of the connecting head 4 can be realized, making it more convenient for the staff to connect this device with external components;

[0039] During the subsequent application process, the reinforcing rods 5 located outside the main universal ball 31 and the main universal housing 3 can improve the strength of the connection part between the main universal ball 31 and the main universal housing 3. Therefore, the phenomenon of cracking and damage at the connection part between the main universal ball 31 and the main universal housing 3 can be reduced;

[0040] At the same time, the protective cover 6 outside the reinforcing rod 5 can also cover and seal the reinforcing rod 5, the main universal ball 31 and the main universal housing 3, and further prevent dust in the air from entering the moving main universal housing 3 and the main universal ball 31 during the subsequent use process and affecting their rotation. Therefore, the flexibility of the subsequent rotation of the connecting head 4 can be ensured.

[0041] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present utility model.
