[0031] The present invention is applicable to the fields of testing equipment and industrial equipment, and the present invention is described below through specific embodiments.

[0032] Please refer to Figure 1-3 The double-hook synchronous opening and closing lock comprises a lock body 1 and a lock block 2 respectively fixed on two relatively moving objects; the lock body 1 comprises a mounting base 11, a left hook 14, a right hook 15, a toggle member 13, a mounting cover 12 and a compression spring 16; the mounting cover 12 is fixedly connected to the mounting base 11 by screws, and the mounting base 11 is provided with a mounting groove 111 with a top opening, and the left hook 14 and the right hook 15 are relatively spaced and arranged in the mounting groove 111, and can rotate relative to the mounting base 11; the toggle member 13 comprises a guide block 131, and a guide block 131 is fixed to the guide block 131. The hook steering push block 132 is connected; the toggle member 13 is movably connected to the left hook 14 and the right hook 15, and the hook steering push block 132 of the toggle member 13 is located in the interval area between the left hook 14 and the right hook 15; the mounting cover 12 is provided with a movable window 121, the guide block 131 is located in the movable window 121, and can move up and down along the movable window 121; the bottom of the hook steering push block 132 is provided with a spring hole 1321, the upper end of the compression spring 16 is installed in the spring hole 1321, and the lower end of the compression spring 16 stops at the bottom of the mounting groove 111.

[0033] When locking is required, the lock body 1 and the lock block 2 are kept within the matching range, and when the guide block 131 is pushed upward to the locking position, the toggle member 13 will simultaneously drive the left hook 14 and the right hook 15 to rotate synchronously inward, so that the left hook 14 and the right hook 15 can be engaged with the lock block 2. When unlocking is required, the guide block 131 is pushed downward to the unlocking position. Due to the existence of the hook turning push block 132, the hook turning push block 132 will force the left hook 14 and the right hook 15 to rotate synchronously outward when moving downward, so that the left hook 14 and the right hook 15 can be disengaged from the lock block 2. It should be noted that due to the provision of the compression spring 16, when no external force acts on the toggle member 13, the compression spring 16 will push the hook turning push block 132 upward, so that the guide block 131 is in the locked position, so that it can always be tightly engaged with the lock block 2 to form a self-locking state.

[0034] For further information, please refer to Figure 2 The lock body 1 also includes a left hook shaft 1121 and a right hook shaft 1131; the mounting base 11 is provided with a left shaft mounting hole 112 and a right shaft mounting hole 113, the left hook 14 is provided with a left shaft hole 142, and the right hook 15 is provided with a right shaft hole 152; the inner end of the left hook shaft 1121 is fixed in the left shaft mounting hole 112, and the left hook shaft 1121 penetrates into the left shaft hole 142 to form a rotational connection between the left hook 14 and the mounting base 11; the inner end of the right hook shaft 1131 is fixed in the right shaft mounting hole 113, and the right hook shaft 1131 penetrates into the right shaft hole 152 to form a rotational connection between the right hook 15 and the mounting base 11.

[0035] For further information, please refer to Figure 4 , also includes a left slide bar 13111 and a right slide bar 13121; the guide block 131 is provided with a left slide bar mounting hole 1311 and a right slide bar mounting hole 1312, the left hook 14 is provided with a left slide groove 143 for the left slide bar 13111 to move, and the right hook 15 is provided with a right slide groove 153 for the right slide bar 13121 to move; the inner end of the left slide bar 13111 is fixed in the left slide bar mounting hole 1311, and the outer end of the left slide bar 13111 is inserted into the left slide groove 143; the inner end of the right slide bar 13121 is fixed in the right slide bar mounting hole 1312, and the outer end of the right slide bar is inserted into the right slide groove 153. Specifically, the left slide groove 143 and the right slide groove 153 are both waist-shaped slide grooves that are arranged obliquely; when the left slide bar 13111 moves to the bottom of the left slide groove 143 and the right slide bar 13121 moves to the bottom of the right slide groove 153, the left hook 14 and the right hook 15 are in a disengaged state from the locking block 2; when the left slide bar 13111 moves to the top of the left slide groove 143 and the right slide bar 13121 moves to the top of the right slide groove 153, the left hook 14 and the right hook 15 are in an engaged state with the locking block 2.

[0036] For further information, please refer to Figure 2 A left engaging groove 141 is provided on the upper end of the left hook 14 on the side opposite to the right hook 15, and a right engaging groove 151 is provided on the upper end of the right hook 15 on the side opposite to the left hook 14; a left protrusion 21 engaging with the left engaging groove 141 is provided on the left side of the locking block 2, and a right protrusion 22 engaging with the right engaging groove 151 is provided on the right side of the locking block 2.

[0037] In this embodiment, the left clamping groove 141 is located above the left shaft hole 142, and the left slide groove 143 is located below the left shaft hole 142; the right clamping groove 151 is located above the right shaft hole 152, and the right slide groove 153 is located below the right shaft hole 152.
