[0026] Example

[0027] like Figure 1-4As shown, this embodiment provides a portable hose crimper, including: a base 100, with folding support legs hinged to both ends of one side of the base 100. In use, the folding support legs can be rotated to unfold the base 100, increasing the contact area between the base 100 and the ground. A crimping assembly 500 is provided on the surface of the base 100. A manual hydraulic pump 300 and an oil tank 400 are provided inside the base 100. The output end of the manual hydraulic pump 300 passes through the base 100 and is detachably connected to a telescopic pressure rod 600. The output end of the oil tank 400 is connected to the input end of the manual hydraulic pump 300 via a pipe. The output end of the manual hydraulic pump 300 is connected to the crimping assembly 500 via a pipe. An unloading valve 301 is provided on the side of the manual hydraulic pump 300.

[0028] In this embodiment, the telescopic pressure rod 600 is installed on the manual hydraulic pump 300. The telescopic pressure rod 600 and the manual hydraulic pump 300 are fixedly connected by threads. Then, the folding support foot is unfolded, and the unloading valve 301 is rotated to prevent the pressure oil from flowing back. The pipe fitting to be crimped is placed into the crimping assembly 500. By manually pressing the telescopic pressure rod 600, the manual hydraulic pump 300 is driven to deliver the pressure oil in the oil tank 400 to the crimping assembly 500, thereby driving the crimping assembly 500 to crimp the pipe fitting. After crimping is completed, the pipe fitting is removed, and the unloading valve 301 is rotated to return the oil. Finally, the telescopic pressure rod 600 is disassembled, and the folding support foot is folded up.

[0029] Furthermore, one end of the folding support leg 200 is hinged to the base 100 via a hinge structure 201. A limiting block 202 is provided on the side of the folding support leg 200, and a locking plate 203 is rotatably connected to the side of the base 100. The locking plate 203 is used to restrict the movement of the limiting block 202. Rotating the hinge structure 201 causes the folding support leg 200 to unfold by 90 degrees, and the locking plate 203 locks the limiting block 202 in place, restricting the movement of the folding support leg 200 and achieving fixation.

[0030] Furthermore, a sleeve 601 is rotatably provided on the side of the base 100, and a tube buckle 602 is provided at the top of the clamping assembly 500. One end of the telescopic pressure rod 600 can be embedded in the sleeve 601, and the other end is fixed by the tube buckle 602. In this embodiment, one end of the sleeve 601 is rotatably connected to the side of the base 100 through a universal joint. By inserting one end of the telescopic pressure rod 600 into the sleeve 601 and the other end into the tube buckle 602, the telescopic pressure rod 600 can be stored.

[0031] Specifically, the clamping assembly 500 includes an end cap 501, a cylinder 502, a piston rod 503, and a pressure block 504. The end cap 501 is fixedly connected to one end of the cylinder 502. The piston rod 503 is movably connected inside the cylinder 502, and the piston rod 503 and the rear end of the cylinder 502 form an oil chamber. The oil chamber is connected to the manual hydraulic pump 300 through a pipe. There are multiple pressure blocks 504, which are arranged in a circumferential array and connected to each other by springs 505. The multiple pressure blocks 504 form a circular through hole. The pressure block 504 is disposed between the cylinder 502 and the piston rod 503, and the pressure block 504 and the piston rod 503 abut against each other through matching inclined surfaces, so that when the piston rod 503 moves axially, it can drive the pressure block 504 to move radially. In this embodiment, the pressure oil in the oil tank 400 is pumped into the oil chamber between the cylinder 502 and the piston rod 503 by the manual hydraulic pump 300. The pressure oil pushes the piston rod 503 to move axially. Since the piston rod 503 and the pressure block 504 are engaged by inclined surfaces, when the piston rod 503 moves, it drives the pressure block 504 to move radially, thereby performing a pipe pressing operation on the pipe located in the middle of the pressure block.

[0032] Specifically, it also includes an adjustment mechanism, which includes a fine-tuning device 701, a contact switch 704, a buzzer 703, and a connecting rod 702. The base 100 is fitted with a threaded seat, and the fine-tuning device 701 is threadedly connected to the threaded seat. One end of the connecting rod 702 is connected to the piston rod 503, and the other end passes through the base 100 and is connected to the buzzer 703. The end of the buzzer 703 near the fine-tuning device 701 is connected to the contact switch 704. The movement of the piston rod 503 drives the connecting rod 702 to move, so that the contact switch 704 contacts the fine-tuning device 701. In this embodiment, the length of the fine-tuning device 701 entering the base 100 is controlled by rotating the fine-tuning device 701. The fine-tuning device 701 can be set with a scale to intuitively display the size of the workpiece to be crimped. After adjusting the fine-tuning device 701, the crimping operation begins. During crimping, the piston rod 503 moves towards the fine-tuning device 701, driving the connecting rod 702, the buzzer 703, and the contact switch 704 to move. When the contact switch 704 contacts the fine-tuning device 701, the contact switch 704 is triggered. The buzzer 703 and the contact switch 704 are connected by a wire, and the buzzer 703 emits a sound. When the operator hears the alarm from the buzzer 703, it proves that the pipe has been crimped in place, and at this time, pressing the telescopic pressure rod 600 can be stopped.

[0033] Furthermore, it also includes an indicator light 705, which is electrically connected to the contact switch 704. When the contact switch 704 is triggered, the indicator light 705 lights up, and a buzzer 703 sounds to indicate to the operator that the button has been properly engaged.

[0034] Furthermore, it also includes a power supply 706, which is electrically connected to the buzzer 703, the contact switch 704, and the indicator light 705. Power is supplied through the built-in power supply 706, eliminating the need for external power cords and making it convenient for carrying and use when out and about.

[0035] Furthermore, a handle 800 is fixedly connected to the top of the clamping assembly 500. When using the device, the operator holds the handle 800 with one hand and presses down on the telescopic lever 600 with the other hand for leverage. Holding down the handle 800 at the same time can further stabilize the device.

[0036] Furthermore, the top of the oil tank 400 is provided with an oil inlet. The oil inlet is provided through the base 100 and is detachably connected to an oil cap 401. When in use, the oil cap 401 is opened to allow air to circulate inside the oil tank 400 so that oil can be smoothly delivered to the oil chamber. At the same time, it can be used to replenish pressure oil.

[0037] The working principle of this utility model is as follows: Before use, open the two folding support feet 200 and clamp the limiting block 202 with the locking plate 203. Then, take the telescopic pressure rod 600 out of the sleeve 601 and fix it to the output end of the manual hydraulic pump 300 by thread. Open the oil cap 401, rotate the unloading valve 301, and rotate the fine adjuster 701 as needed. After adjustment, insert the pipe fitting into the middle of the pressure block 504 and press the telescopic pressure rod 600 to perform the pipe pressing operation. After triggering the contact switch 704, the operator will hear the buzzer 703 or see the indicator light 705 light up. Stop pressing, rotate the unloading valve 301 to allow the pressure oil to flow back, and the spring 505 connected to the pressure block 504 will push the piston rod 503 to reset. Then, remove the pipe fitting. Finally, retract the folding support feet 200, disassemble the telescopic pressure rod 600, and insert it into the sleeve 601 and the pipe buckle 602.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
