DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] A convenient installation device for an oil cylinder, as Figures 1 - 4 shown, includes a cylinder barrel 1 and a piston rod 2 slidably connected to the cylinder barrel 1. The cylinder barrel 1 is provided with an inlet and outlet for accommodating liquid infusion. A connecting portion 3 is provided at the bottom of the cylinder barrel 1. Threads are provided on the outer sides of the cylinder barrel 1 and the connecting portion 3. Several clamping members 4 are elastically arranged outside the connecting portion 3, and the clamping members 4 are elastically arranged. A rotating member 5 for pushing the clamping members 4 to deform and clamp is threadedly connected to the cylinder barrel 1 and the connecting portion 3. The clamping members 4 are also threadedly connected to the rotating member 5. A clamping groove 6 for accommodating an object to be inserted is provided on the clamping members 4 and the connecting portion 3. When this device is used and installation is required, an external object or plug is inserted into the clamping groove 6 of the clamping members 4 at the bottom of the cylinder barrel 1 and the connecting portion 3 to achieve connection. Then, the rotating member 5 is rotated along the thread of the cylinder barrel 1 and moved to the connecting portion 3 and then rotated onto the clamping members 4. The opening degree of the clamping members 4 in the normal state is relatively large. By continuously rotating the rotating member 5, the elastic clamping members 4 are compressed and pressed tightly against the plug inserted into the clamping groove 6. Thus, several clamping members 4 surround and simultaneously abut against the externally inserted object to achieve the clamping effect, and the fixation at the bottom achieves the installation effect, avoiding the need to install other objects in the prior art, or fixing by surrounding the cylinder barrel 1 with iron sheets and then using bolts and nuts. Through the above settings, the installation is convenient and does not require external tools and devices, which is convenient and fast. At the same time, if it is not easy to install on the side, this setting is also convenient for installation.

[0020] The cylinder 1 is provided with a reinforcement assembly, which includes a moving block 7 arranged at the threaded portion of the bottom of the cylinder 1, the moving block 7 is slidably connected to the cylinder 1, a clip 8 is rotatably connected to the moving block 7, and a convex portion 9 for abutting the outside of the clip 8 is provided on the outside of the clip 8, and a limiting assembly is provided on the cylinder 1, the limiting assembly includes a limiting piece 10 slidably connected to the cylinder 1, the moving block 7 is provided with a limiting groove 11 for accommodating the limiting piece 10 to be embedded, a spring 12 is provided between the moving block 7 and the cylinder 1, and a contact block 13 for pressing the clip 8 to open is provided on the side of the rotating member 5 close to the moving block 7. Secondly, if the installation position is inconvenient to install at the bottom and can only be installed on the side, the limiting assembly can be released by pushing the limiting piece 10 downward, and after disengaging from the limiting groove 11 of the moving block 7, the moving block 7 is pushed outward by the spring 12, thereby passing through the cylinder 1 and driving the clip 8 to move out at the same time, thereby rotating the rotating member 5 backward The clamp 8 is moved and the abutment block 13 on the rotating member 5 abuts against the clip 8. Because the clip 8 moves outward, the abutment block 13 abuts against the rear end of the clip 8, thereby pushing the clip 8 to rotate and the outer end of the clip 8 opens and moves away from the moving block 7, and at the same time drives the protrusion 9 outward, so that the moving block 7 and the clip 8 that pass through the cylinder 1 can be embedded in the groove or through the through-hole to be installed during installation, so that the protrusion 9 and the clip 8 are opened and abutted on the outside of the through-hole or the groove, so as to achieve the effect of restriction and fixation, and the clip 8 is restricted by the abutment block 13 on the rotating member 5, so as to ensure that the clip 8 will not close and will not leave the installation groove. After the above arrangement, it can be fixed by the side or by the bottom, and there is no need to install an additional installation component, nor is there a need for bolts and nuts to fix, so as to avoid the need for external tools. The installation is convenient and quick with this arrangement.

[0021] Secondly, if the side needs to be reinforced after the bottom is fixed, the rear end of the rotating member 5 can be separated and rotated backward alone to drive the abutment block 13 to move, so that the clip 8 can be opened and embedded in the externally installed groove, so that the double fixation has a reinforcement effect. A torsion spring 14 is provided between the clip 8 and the moving block 7, and when disassembly is required, the abutment block 13 is separated from the clip 8 and rotated back, so that the torsion spring 14 can be reset and the clip 8 can be pushed back, so that the clip 8 can be pulled out of the groove again and pushed to reset and re-embedded on the cylinder 1, and re-embedded in the limiting groove 11 through the limiting member 10, so as to achieve the effect of automatic reset.
