Lack of position feedback mechanism: During the rotation of the mast, there is no effective way to provide real-time position information, making it difficult for the operator to accurately judge whether the mast has reached the predetermined position. Lack of mechanical locking device: The existing design is not equipped with a mechanical locking mechanism. In the event of failure of the push cylinder or other drive components, the mast may lose support, resulting in safety risks. Utility Model Content

[0003] The main purpose of the utility model is to provide a rocker slider type lightweight folding mast to solve the problems in the above background technology.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: comprising a base, a rotating mast is provided on the base, a hinge seat is fixedly provided at the middle of one end of the bottom of the mast, a rotating rocker is provided between the hinge seat and the base, and the middle of the rocker is connected to the base through a push cylinder;

[0005] There are hinge ears on both sides of the hinge seat, which are fixed on the base. The hinge ears are rotated against the base through the pin shaft;

[0006] A locking oil cylinder is fixedly arranged in the base, a locking pin is fixedly arranged at the end of the mast, and a latch is fixedly arranged at the end of the piston rod of the locking oil cylinder, and the latch is abutted against the locking pin.

[0007] Preferably, two detection rods are fixed on the outside of the hinged ears of the mast in the horizontal and vertical states, and two proximity switches are correspondingly fixed in the base. The rotation of the mast makes the two detection rods align with the corresponding proximity switches, thereby feeding back the mast rotation into position signal.

[0008] Preferably, a first rotating seat and a second rotating seat are respectively fixed at both ends of the bottom of the base, the end of the rocker arm is hinged to the first rotating seat through a pin, the end of the cylinder barrel in the push cylinder is hinged to the second rotating seat through a pin, and the end of the piston rod is hinged to the middle of the rocker arm through a pin.

[0009] Preferably, a sliding groove is provided at the end of the rocker, and a rotating sliding rod is provided on the hinge seat, and the sliding rod moves against the sliding groove.

[0010] Preferably, the locking cylinder is fixed in the base via a mounting seat, and the latch slides against the base.

[0011] The utility model provides a rocker slider type lightweight folding mast, which has the following beneficial effects:

[0012] 1. The optimized articulated structure and automatic control system simplify the mast's transition from horizontal to vertical, reducing the need for manual intervention. The introduction of a position detection and feedback system allows the operator to understand the mast's position in real time, further improving operational convenience and accuracy.

[0013] 2. A mechanical locking device ensures that when the mast is in a vertical position, even if the push cylinder fails, the mast will remain stable and will not collapse unexpectedly. The position feedback mechanism provides precise position information through proximity switches and detection rods, avoiding safety risks caused by inaccurate position judgment.

[0014] 3. The design of the slide and slide bar enhances the connection stability between the rocker and the articulated seat, reduces wear caused by friction, and extends the service life of the equipment. The mechanical locking device provides additional safety. Even in the event of a hydraulic system failure, it can ensure the safe locking of the mast, increasing the overall reliability of the system.

[0015] 4. Automated control and precise position feedback speed up the raising and lowering of the mast, reducing operation time and improving work efficiency. By reducing manual intervention, the possibility of human error is reduced, further improving the efficiency and quality of operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figures 1 to 7 As shown, the rocker slider type lightweight folding mast includes a base 1, a rotating mast 2 is provided on the base 1, a hinge seat 3 is fixed at the middle of one end of the bottom of the mast 2, a rotating rocker 4 is provided between the hinge seat 3 and the base 1, and the middle of the rocker 4 is connected to the base 1 through a push cylinder 7;

[0026] The hinge base 3 is provided with hinge ears 5 on both sides, and the hinge ears 5 are fixed on the base 1. The hinge ears 5 are rotated against the base 1 through the pin 6;

[0027] A locking cylinder 8 is fixed in the base 1 , a locking pin 9 is fixed at the end of the mast 2 , and a latch 10 is fixed at the end of the piston rod of the locking cylinder 8 , which abuts against the locking pin 9 .

[0028] The pushing cylinder 7 drives the rocker 4 to rotate, thereby pushing the hinge seat 3 to rotate, so that the mast 2 can be rotated against the base 1 through the hinge ear 5 and the pin 6; when the mast 2 is in a vertical state, the locking cylinder 8 drives the pin 10 to be pressed against the locking pin 9 at the end of the mast 2, thereby locking the mast 2 on the base 1.

[0029] Base 1 serves as the foundation for the entire device. Push cylinder 7 drives the rocker arm, thereby changing the mast's position. Locking cylinder 8, locking pin 9, and latch 10 lock the mast to the base when it's vertical, ensuring stability.

[0030] Preferably, two detection rods 501 are fixed on the outside of the hinged ears 5 in the horizontal and vertical states of the mast 2, and two proximity switches 12 are correspondingly fixed in the base 1. The mast 2 rotates so that the two detection rods 501 are aligned with the corresponding proximity switches 12, thereby feeding back a signal that the mast 2 has rotated into position.

[0031] The detection rod 501 is fixed to the outside of the hinge ear 5 and moves with the rotation of the mast 2. The proximity switch 12 is installed in the base 1 and corresponds to the detection rod 501. When the detection rod 501 is aligned with the proximity switch 12, the proximity switch is triggered.

[0032] When the mast 2 rotates from one position to another, for example, from horizontal to vertical or vice versa, the detection rod 501 fixed to the hinge ear also moves. When the mast 2 reaches the predetermined position, that is, completely horizontal or completely vertical, the corresponding detection rod 501 will accurately align and activate the corresponding proximity switch 12. When the proximity switch 12 is activated, it generates an electrical signal that can be received by the control system to confirm whether the mast has been correctly rotated to the specified position. Once the control system receives the correct feedback signal, it can take the next step, such as stopping the action of the push cylinder 7 or activating the locking cylinder 8 to lock the mast 2.

[0033] Preferably, a first rotating seat 101 and a second rotating seat 102 are respectively fixed at both ends of the bottom of the base 1, the end of the rocker 4 is hinged to the first rotating seat 101 through a pin, the end of the cylinder barrel in the push cylinder 7 is hinged to the second rotating seat 102 through a pin, and the end of the piston rod is hinged to the middle of the rocker 4 through a pin.

[0034] The first rotating seat 101 is located at one end of the base, and one end of the rocker arm 4 is hinged to the first rotating seat via a pin. This design allows the rocker arm to rotate around the first rotating seat, thereby adjusting the angle of the mast 2. The second rotating seat 102 is located at the other end of the base, and the cylinder end of the push cylinder 7 is hinged to it via a pin. This allows the push cylinder to rotate within a certain range relative to the base to adapt to the movement of the rocker arm. The piston rod end of the push cylinder 7 is hinged to the middle of the rocker arm 4 via another pin. In this way, when the push cylinder is extended or retracted, it can effectively push or pull the rocker arm, thereby changing the angle of the mast.

[0035] Preferably, a sliding groove 401 is provided at the end of the rocker 4 , and a rotating sliding rod is provided on the hinge seat 3 , and the sliding rod moves against the sliding groove 401 .

[0036] A slot 401 is provided at one end of the rocker 4. This slot provides a path for the slide bar to move within. The slide bar is mounted on the hinged base 3 and can slide freely within the slot 401. This design allows the slide bar to move with the rocker 4 while maintaining its connection to the rocker.

[0037] By restricting the movement of the slide bar within the slide groove 401, the relative position between the rocker arm 4 and the hinge seat 3 remains stable even under external forces, thereby improving the stability of the entire device. The combination of the slide groove and the slide bar reduces the number of direct contact points, which helps reduce wear caused by friction and extend the service life of the device.

[0038] The movement path of the slide bar in the slide groove is fixed, which can simplify the management of the movement trajectory of the rocker 4 by the control system, making the raising and lowering process of the mast 2 more controllable and smooth.

[0039] Preferably, the locking cylinder 8 is fixed in the base 1 through the mounting seat 11, and the latch 10 slides against the base 1. Further preferably, the matching surfaces of the locking pin 9 and the latch 10 are inclined surfaces, and the mast 2 can be locked on the base 1 through the inclined surfaces.

[0040] Mounting bracket 11 is a structural component used to secure locking cylinder 8, ensuring it is securely mounted within base 1. The mounting bracket is typically made of a sturdy material to withstand the forces generated during the locking process and maintain the cylinder's position. Locking cylinder 8 is secured within base 1 via mounting bracket 11, ensuring stability and reliability during operation. The locking cylinder's primary function is to drive latch 10, thereby locking or unlocking mast 2.

[0041] One end of the latch pin 10 is fixed to the locking cylinder piston rod, and the other end is designed to be inserted into the locking pin 9 at the end of the mast. When the locking cylinder is activated, it pushes the latch pin forward or backward.

[0042] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
