Description

Technical Field

[0001] The utility model belongs to the technical field of automotive inspection tools, and particularly relates to a flipable locking device for automotive inspection tools. Background Art

[0002] At present, when automotive inspection tools are in use, elbow clamps are generally used to fix them on the workbench. The structure of the elbow clamp is mainly based on the design of a linkage mechanism, which is composed of four components: a connecting rod, a frame, and two crank-rocker arms. This structure utilizes the principle of a double-rocker mechanism in a planar four-bar mechanism. When the three hinge points of the connecting rod and the crank-rocker arm and the hinge point of one of the crank-rocker arms and the frame are on the same straight line, the mechanism is in a dead point position. At this position, the workpiece being pressed, no matter how large the reaction force (except for a destructive reaction force), cannot make the pressure head loosen. However, the current elbow clamps are generally fixed on the workbench. When fixing different automotive inspection tools, the angles and directions that the elbow clamps need to press are also different. The current elbow clamps cannot be flipped to adjust the angle. Generally, bases with different angles need to be set to change the pressing direction of the elbow clamps, which is inconvenient when fixing the elbow clamps, and the subsequent clamping is unstable and not conducive to flipping and adjustment.

On one side of the upper side of the base block 1, a first connecting rod 2 is rotatably arranged. On the side of the upper side of the base block 1 far from the first connecting rod 2, a second connecting rod 3 is rotatably arranged. On the upper side of the second connecting rod 3, a first support rod 5 is rotatably arranged. On the lower side of the middle of the first support rod 5, a connecting rod 4 is arranged. The connecting rod 4 is rotatably connected to the upper end of the first connecting rod 2. On the side of the first support rod 5 far from the second connecting rod 3, a handle sleeve 6 is arranged. On the upper side of the side of the second connecting rod 3 far from the first support rod 5 and perpendicular to the second connecting rod 3, a second support rod 7 is arranged. On the side of the second support rod 7 far from the second connecting rod 3, a pressing rod 8 is arranged. The lower end of the pressing rod 8 penetrates through the second support rod 7 to the lower side and is provided with a pressing block 10. On the lower side of the base block 1, insertion rods 13 are symmetrically arranged. On the lower side of the base block 1, an arc - shaped installation platform 14 is arranged. On the upper side of the arc - shaped installation platform 14, sliding grooves 15 are symmetrically arranged. The insertion rods 13 penetrate through the sliding grooves 15 to the lower side of the arc - shaped installation platform 14 and are threadedly provided with nuts two 16. On the lower sides of both sides of the arc - shaped installation platform 14, mounting plates 18 are arranged. On the upper sides of the mounting plates 18, mounting holes are symmetrically arranged. When meeting the clamping requirements of different vehicle inspection fixtures, only need to make the insertion rods 13 slide along the sliding grooves 15, and then tighten the nuts two 16 to fix the insertion rods 13, then the pressing direction and angle of the mounting plates 18 can be freely flipped within the range of the sliding grooves 15. When installing this device, the restrictions of angle and direction are weakened, increasing the convenience of installing this device, and facilitating subsequent adjustment of the pressing direction and angle. On the lower side of the base block 1, a stabilizing arc plate 17 is arranged. The stabilizing arc plate 17 is attached to the upper side surface of the arc - shaped installation platform 14. The insertion rods 13 penetrate through the stabilizing arc plate 17 to the lower side. Setting the stabilizing arc plate 17 attached to the upper side of the arc - shaped installation platform 14 is convenient for increasing the stability of the elbow clamp body relative to the arc - shaped installation platform 14. The second support rod 7 is penetrated up and down.

On the upper and lower sides of the second support rod 7, clamping blocks 11 are slidably clamped. The pressing rod 8 is inserted into the clamping blocks 11. The nuts one 9 are arranged on the sides of the clamping blocks 11 away from each other. Setting the clamping blocks 11 can assist the pressing rod 8 and enhance the stability of the pressing rod 8 relative to the second support rod 7. The outer side of the pressing block 10 is coated with a rubber buffer layer to increase the buffer protection for pressing the vehicle inspection fixture. On the lower side of the pressing rod 8, a connecting cylinder 12 is threadedly arranged. The lower side of the connecting cylinder 12 is fixedly connected to the pressing block 10. By screwing the connecting cylinder 12, the connecting cylinder 12 rotates threadedly relative to the pressing rod 8 to adjust the pressing height of the pressing block 10.

[0030] The working principle and usage process of the present utility model:

[0031] During use, when both the first support rod 5 and the second support rod 7 are in a horizontal state, the rotation connection point between the first support rod 5 and the second connecting rod 3 and the first connecting rod 2 are in a straight line. At this time, due to the principle of the double rocker mechanism in the planar four-bar mechanism, the connection point between the first connecting rod 2 and the connecting rod 4 is at the dead center position of downward rotation, that is, the first connecting rod 2 can no longer rotate towards the side close to the base block 1. Since the pressing block 10 clamps towards the side away from the second support rod 7, the second support rod 7 is subjected to a reaction force in the direction away from the vehicle jig and is lifted from the direction of the second support rod 7. Eventually, the connecting rod 4 acts on the first connecting rod 2 to rotate downward. Since the connection point between the first connecting rod 2 and the connecting rod 4 is at the dead center position of downward rotation, the second support rod 7 cannot be lifted, thus maintaining stable pressing on the vehicle jig. However, the connection point between the first connecting rod 2 and the connecting rod 4 is at the live center position of upward rotation. By lifting the first support rod 5, the connecting rod 4 can be easily driven to make the first connecting rod 2 rotate upward. At the same time, the first support rod 5 will pull the second connecting rod 3 to drive the second support rod 7 to lift, and the pressing on the vehicle jig can be easily released. When meeting the clamping requirements for different vehicle jigs, only need to make the plug rod 13 slide along the sliding groove 15, and then tighten the second nut 16 to fix the plug rod 13, so that the pressing direction and angle of the mounting plate 18 can be freely flipped within the range of the sliding groove 15. When installing this device, the limitations of angles and directions are weakened, increasing the convenience of installing this device and facilitating subsequent adjustment of the pressing direction and angle. In addition, during use, a stable arc plate 17 is provided on the lower side of the base block 1, and the stable arc plate 17 is arranged in a fitting manner with the upper side of the arc mounting table 14. The plug rod 13 penetrates through the stable arc plate 17 to the lower side. The stable arc plate 17 is arranged in a fitting manner with the upper side of the arc mounting table 14, which is convenient for increasing the stability of the elbow clamp body relative to the arc mounting table 14. In addition, during use, the second support rod 7 is penetrated up and down, and nuts 9 are threadedly fastened on both the upper and lower sides of the outer side of the pressing rod 8 with respect to the second support rod 7 for disassembling the pressing rod 8, and the pressing rod 8 can slide relative to the second support rod 7 to adjust the pressing position. In addition, during use, clamping blocks 11 are slidably clamped on both the upper and lower sides of the second support rod 7, the pressing rod 8 is inserted into the clamping blocks 11, and the nuts 9 are arranged on the sides where the clamping blocks 11 are away from each other. The clamping blocks 11 are provided to assist the pressing rod 8 and enhance the stability of the pressing rod 8 relative to the second support rod 7. In addition, during use, a rubber buffer layer is coated on the outer side of the pressing block 10 to increase the buffer protection for pressing the vehicle jig. In addition, during use, a connecting cylinder 12 is threadedly arranged on the lower side of the pressing rod 8, and the lower side of the connecting cylinder 12 is fixedly connected to the pressing block 10. By screwing the connecting cylinder 12, the connecting cylinder 12 rotates threadedly relative to the pressing rod 8 to adjust the pressing height of the pressing block 10.
