Description

Technical Field

[0001] The utility model relates to a double-sided synchronous locking mechanism, in particular to a novel single electric cylinder double-sided synchronous locking mechanism. Background Art

[0002] At present, there are several forms of synchronous locking mechanisms on both sides:

[0003] One is to configure electric cylinders (or other linear telescopic components) on both sides, which has the disadvantages of high cost and complex structure;

[0004] The other is a single electric cylinder (or other linear telescopic components) with double-sided locking, which is usually fixed at one end and acts on both sides at the same time. The structure is large and complex, and it is difficult to synchronize the double-sided locking, and the locking stability is poor. Figure 4 As shown, if the rotating rod needs to rotate synchronously in real time, angle A and angle B need to rotate simultaneously and synchronously. When simply using the electric cylinder, since the two ends of the electric cylinder are not fixed, when the electric cylinder is extended or retracted, the positions of the connection points on both sides of the electric cylinder are not fixed and are random. Therefore, the angles between the rotating rods and the fixed brackets on both sides, angle A and angle B, cannot be equal in real time and cannot change synchronously. Utility Model Content

[0005] In order to solve the defects and shortcomings of the above-mentioned prior art, the utility model provides a new single-electric cylinder double-sided synchronous locking mechanism which can keep the rotating rods on both sides synchronized and rotate at the same angle by only using a single electric cylinder or other type of one-way telescopic mechanism.

DETAILED DESCRIPTION

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings, but this does not limit the protection scope of the present invention.

[0020] like Figure 1 and 2 As shown, a novel single electric cylinder double-sided synchronous locking mechanism comprises a fixed bracket 1, an electric cylinder 2 and two rotating rods 3 connecting the fixed bracket 1 and the electric cylinder 2. The two ends of the fixed bracket 1 are respectively rotatably connected to the middle of the rotating rod 3, the fixed end of the electric cylinder 2 is connected to a fixed end extension rod 5, the other end of the fixed end extension rod 5 is rotatably connected to the end of one of the rotating rods, the fixed bracket 1 is connected to the fixed end extension rod 5 through a slider assembly, the electric cylinder 2 and the fixed bracket 1 always remain parallel under the action of the slider assembly, the movable end of the electric cylinder 2 is rotatably connected to the end of the other rotating rod, and when the electric cylinder 2 is actuated, the two rotating rods rotate inward or outward synchronously and at the same angle.

[0021] The slider assembly includes a vertical slider 4 and a horizontal slider 10. The horizontal slider 10 is fixed to one end of the vertical slider 4. The vertical slider 4 is slidably connected to the fixed end extension rod 5 in the vertical direction. The horizontal slider 10 is slidably connected to the fixed bracket 1 in the horizontal direction. The fixed end extension rod 5 is provided with a vertical slide rail 12 that matches the vertical slider 4. The vertical slider 4 is provided with a vertical slide groove 14 that matches the vertical slide rail 12. The fixed bracket 1 is provided with a horizontal slide rail 13 that matches the horizontal slider 10.

[0022] The movable end of the electric cylinder 2 is connected to a movable end extension rod 6, and the end of the movable end extension rod 6 is rotatably connected to the end of another rotating rod.

[0023] A rotating rod connecting section 8 is provided at both ends of the fixed bracket 1, and the rotating rod connecting section 8 is L-shaped. The middle part of the rotating rod 3 is rotatably connected to the outer end of the rotating rod connecting section 8. The thickness of the rotating rod connecting section 8 is greater than the thickness of the fixed bracket 1, and one end of the horizontal slide rail 13 is fixed to the inner end of one of the rotating rod connecting sections.

[0024] The outer ends of the rotating rod connecting section 8, the outer ends of the fixed end extension rod 5, and the outer ends of the movable end extension rod 6 are all provided with rotating rod connecting grooves 9 that match the rotating rod 3. The ends of the rotating rod 3 extend into the corresponding rotating rod connecting grooves 9 and are rotatably connected through the rotating shaft 7.

[0026] The action principle of the utility model is as follows Figure 3 As shown, a set of mutually perpendicular sliders are added to ensure that the electric cylinder structure is parallel to the fixed bracket; the opposite sides are equal and the angles are equal, and another set of quadrilaterals with parallel opposite sides are isosceles trapezoids; the parallel sliders are used to compensate for the horizontal displacement when the electric cylinder mechanism is extended, and the vertical sliders are used to compensate for the vertical displacement of the electric cylinder assembly, while ensuring that the electric cylinder assembly is always parallel to the fixed bracket, so that the rotation angles of the rotating rods on both sides are always equal.

[0027] In the utility model, the movable end of the electric cylinder refers to the piston end of the electric cylinder (which can move with the extension and contraction of the piston), and the fixed end of the electric cylinder refers to the cylinder body end of the electric cylinder (which is fixed).

[0028] In the utility model, the displacement of the vertical slider on the vertical slide rail is smaller than the length of the vertical slide rail itself, and the displacement of the horizontal slider on the horizontal slide rail is also smaller than the length of the horizontal slide rail itself. Therefore, it is completely possible to prevent the vertical slider or the horizontal slider from falling off.

[0029] The electric cylinder in the utility model can be replaced by other types of one-way telescopic mechanisms.
