DETAILED DESCRIPTION

[0028] Example 1

[0029] See Figures 1 to 15The present invention comprises a cylinder 1, a mounting plate 2, a lower guide plate 3, a pin seat 4, an upper guide plate 6 and two connecting plates 5.

[0030] The cylinder 1 is connected to the mounting plate 2. Two connecting plates 5 are respectively connected to the front and rear sides of the mounting plate 2, the lower guide plate 3 and the upper guide plate 6 are connected between the two connecting plates 5, and the two connecting plates 5 and the mounting plate 2 or the lower guide plate 3 or the upper guide plate 6 adopt a concave-convex embedded structure and are connected by screws.

[0031] The pin shaft seat 4 is provided with two vertical strip steel belt grooves 4-a, which divide the pin shaft seat 4 into three parts: the side part 4-1, the middle part 4-2 and the side part 4-1. The upper ends of the two side parts 4-1 and the one middle part 4-2 are provided with horizontal pin shaft holes 4-c, and the middle part 4-2 has a vertical pull rod hole 4-b.

[0034] The upper guide plate 6 is provided with a vertical central hole 6-b, and an upper guide groove 6-a is provided on the front and rear sides of the bottom surface thereof. The upper guide plate 6 can be a whole piece. Considering the convenience of installation, the embodiment adopts that the upper guide plate 6 is composed of three independent side upper guide plates 6-1, a middle upper guide plate 6-2 and a side upper guide plate 6-1. The two side upper guide plates 6-1 and the one middle upper guide plate 6-2 correspond to the two side parts 4-1 and the middle part 4-2 of the pin shaft seat 4 respectively. The upper guide groove 6-a is provided on the front and rear sides of the bottom of the two side upper guide plates 6-1 and the one middle upper guide plate 6-2. The central hole 6-b is located on the middle upper guide plate 6-2.

[0035] The front and rear sides of the pin seat 4 correspond to two side parts 4-1 and one middle part 4-2, respectively, and are provided with two side clamping blocks 7-1 and one middle clamping block 7-2, and the middle clamping block 7-2 is located between the two side clamping blocks 7-1. The upper and lower ends of each side clamping block 7-1 are respectively matched with the upper guide groove 6-a of the side upper guide plate 6-1 and the lower guide groove 3-a of the lower guide plate 3, and the upper and lower ends of the middle clamping block 7-2 are respectively matched with the upper guide groove 6-a of the middle upper guide plate 6-2 and the lower guide groove 3-a of the lower guide plate 3. Since a plurality of long waist countersunk holes 3-c for containing lubricating oil are provided in the lower guide groove 3-a, all the clamping blocks can slide smoothly in their corresponding lower guide grooves 3-a. The side clamping block 7-1 is provided with a first oblique waist-shaped groove 7-1-a, and the middle clamping block 7-2 is provided with a second oblique waist-shaped groove 7-2-a.

The inclination angle is calculated based on the parameters of the product.

[0036] The piston rod 1-1 of the cylinder 1 extends upward through the hollow area of ​​the mounting plate 2, and a pull rod 9 is connected to the piston rod 1-1. The pull rod 9 extends upward through the pin seat hole 3-b of the lower guide plate 3, the pull rod hole 4-b of the pin seat 4 and the central hole 6-b of the middle upper guide plate 6-2.

[0037] The middle part 4-2 and the upper ends of the two side parts 4-1 of the pin shaft seat 4 are provided with pin shaft holes 4-c, and the pin shaft holes 4-c of the two side parts 4-1 are provided with first pin shafts 8-1, and the two ends of each first pin shaft 8-1 enter the first oblique waist-shaped groove 7-1-a of the side clamping block 7-1 on the front and rear sides respectively. The pin shaft hole 4-c of the middle part 4-2 is provided with a second pin shaft 8-2, and the second pin shaft 8-2 passes through the radial hole 9-a of the pull rod 9, and its two ends enter the second oblique waist-shaped groove 7-2-a of the middle clamping block 7-2 on the front and rear sides respectively. The front and rear parts of the first pin shaft 8-1 and the second pin shaft 8-2 extending out of the pin shaft seat are provided with elastic retaining rings 11 to limit the pin shaft axially. The pin shaft seat 4 and the pull rod 9 are connected by the second pin shaft 8-2. When the pull rod 9 drives the pin shaft seat 4 to descend, the pin shaft seat hole 3-b of the lower guide plate 3 provides a space for the pin shaft seat 4 to descend.

[0038] The upper part of the pull rod 9 is provided with an elastic component 10, which includes a spring sleeve 10-1, a spring 10-2, and an adjusting nut 10-5. The spring sleeve 10-1 is cross-shaped, and the lower part is inserted into the central hole 6-b of the middle upper guide plate 6-2 and connected to the upper guide plate 6 by screws. The spring 10-2 is sleeved on the pull rod 9 and is located in the spring sleeve 10-1. The upper end of the spring 10-2 abuts against the upper limit sleeve 10-3 that is movably matched on the pull rod 9, and the lower The end abuts against the shoulder of the pull rod 9. In the embodiment, a lower limit sleeve 10-6 is provided on the shoulder of the pull rod 9. The lower end of the spring 10-2 abuts against the lower limit sleeve 10-6.

The spring 10-2 is adjusted to a suitable length by the adjusting nut 10-5.

[0039] The cylinder is controlled by a solenoid valve. The cylinder runs, drives the pull rod, and drives the pin seat 4 to move through the second pin 8-2. Since the first pin and the second pin move in the oblique waist groove of their respective clamping blocks, they can drive their respective clamping blocks to move horizontally. The steel belt 30 moves in the passage groove 5-a and the steel belt groove 4-a.

[0040] See Figure 1 , 2 4. When one side of the solenoid valve is energized, the cylinder piston rod extends, driving the pull rod 9 to rise, so that the middle clamping block 7-2 and the side clamping block 7-1 on the right side move toward each other, thereby clamping the right steel belt 30; when the other side of the solenoid valve is energized, the cylinder piston rod retracts, driving the pull rod 9 to descend, and the middle clamping block and the side clamping block on the left side move toward each other, thereby loosening the right steel belt and clamping the left steel belt. When the steel belts on both sides do not need to be clamped, the cylinder is de-energized, and the appropriate length of the spring 10-2 makes the cylinder piston rod free.
