Description

Technical Field

[0001] This invention relates to the field of anti-tipping locking devices, and in particular to a highly adaptable anti-tipping locking device. Background Technology

[0002] In modern engineering machinery, some goods are placed vertically during use and require rapid release of all restraints at specific times. To prevent the risk of tipping over due to external forces such as wind loads when the goods are upright, anti-tipping locking devices are used for temporary restraint, and the restraints are released promptly under predetermined conditions.

[0003] In practical applications, the only fixed docking point for this type of cargo is at the bottom, and the weight, volume, and specifications of the goods vary greatly. Traditional anti-tipping locking mechanisms require a one-to-one non-standard design for the cargo diameter; if the diameter changes, a redesign is necessary, resulting in significant waste and keeping the cost of using anti-tipping locking devices high. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention proposes a highly adaptable anti-tipping locking device. This highly adaptable anti-tipping locking device can constrain goods of different diameters by adjusting the locking mechanism's position in the front and rear of the fixed frame. At the same time, it can adapt to different specifications of connecting bolts by changing the lock head or altering the shape of the insertion port, thus exhibiting strong versatility.

[0005] A highly adaptable anti-tipping locking device includes a fixed frame and a locking mechanism installed in the fixed frame. The locking mechanism is arranged in a uniform array along the circumference and can be adjusted in multiple stages along the radial direction.

[0006] The locking mechanism includes lock heads, positioning plates, and nut blocks arranged in parallel from top to bottom. Two sets of lock heads are arranged opposite each other for clamping mating bolts. Slide rails are horizontally arranged on the front and rear sides of the lock heads. The slide rails are fixedly connected to the positioning plates. The lock heads, positioning plates, nut blocks, and slide rails are connected by a linkage mechanism. The nut blocks are driven to rise and fall by a motor, coupling, and screw. When the nut blocks rise and fall, the linkage mechanism is used to open and close the two sets of lock heads.

[0007] As a preferred embodiment of the above technical solution, the linkage mechanism is provided in two parallel sets. Each set of the linkage mechanism includes two sets of triangular connecting rods arranged symmetrically, a rotating shaft, a threaded pin one, and a threaded pin two that cooperate with the triangular connecting rods. One corner of the triangular connecting rod is connected to the positioning plate through the rotating shaft. A sliding groove one is provided symmetrically on the triangular connecting rod relative to the rotating shaft. A sliding groove two is provided horizontally on the slide rail plate. The threaded pin one passes through one set of sliding groove one and sliding groove two in sequence and is fixedly connected to the lock head. The threaded pin two passes through another set of sliding groove one and is fixedly connected to the nut block.

[0008] As a preferred embodiment of the above technical solution, the motor is positioned at the bottom of the positioning plate via a mounting bracket.

[0009] As a preferred embodiment of the above technical solution, multiple sets of guide rods are installed and fixed between the mounting bracket and the positioning plate, and the guide rods slide through the nut block via bushings.

[0010] As a preferred embodiment of the above technical solution, the fixing frame is composed of an upper annular top plate, a lower annular bottom plate, an inner side plate, and a vertical plate that is vertically connected to the upper annular top plate, the lower annular bottom plate, and the inner side plate, and the locking mechanism is suspended at the bottom of the upper annular top plate.

[0011] As a preferred embodiment of the above technical solution, the upright plate is provided with a sliding positioning groove for installing the locking mechanism. The sliding positioning groove is provided with one or more sets of positioning holes. The positioning plate and the upright plate are locked together by a wing screw passing through the positioning hole.

[0012] As a preferred embodiment of the above technical solution, the positioning plate has multiple sets of positioning holes that cooperate with the wing screw. The wing screw can achieve multi-level adjustment of the position of the locking mechanism by connecting to the positioning holes at different positions.

[0013] As a preferred embodiment of the above technical solution, the lock head is provided with a waist-shaped hole along its vertical edge to cooperate with the threaded pin.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The locking mechanism can be adjusted in the front and rear positions of the fixed frame to restrain goods of different diameters.

[0016] 2. The lock head can be replaced or the shape of the socket can be changed to accommodate different sizes of connecting bolts.

[0017] 3. The locking mechanism can be remotely controlled via a remote motor.

[0018] 4. The overturning force is borne by the fixed frame, which enhances the structural strength and can achieve anti-tipping protection for large-mass goods. Attached Figure Description

Detailed Implementation

[0025] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] like Figures 1 to 5 The invention relates to a highly adaptable anti-tipping locking device, which includes a fixed frame 1 and a locking mechanism 2 installed in the fixed frame 1. The locking mechanism 2 is arranged in a uniform array along the circumference and can be adjusted in multiple stages along the radial direction.

[0027] The locking mechanism 2 includes a lock head 3, a positioning plate 4, and a nut block 5 arranged in parallel from top to bottom. Two sets of lock heads 3 are arranged opposite each other for clamping the mating bolts 6 (the mating bolts 6 are the interface and are part of the target item). Slide rails 7 are arranged horizontally on the front and rear sides of the lock head 3. The slide rails 7 are fixedly connected to the positioning plate 4. The lock head 3, positioning plate 4, nut block 5, and slide rails 7 are connected by a linkage mechanism. The nut block 5 is driven to rise and fall by a motor 8, a coupling 9, and a screw 10. When the nut block 5 rises and falls, the two sets of lock heads 3 are opened and closed by the linkage mechanism.

[0028] In this embodiment, the linkage mechanism is arranged in two parallel sets. Each set of the linkage mechanism includes two sets of triangular connecting rods 11 arranged symmetrically, and a rotating shaft 12, a threaded pin 13, and a threaded pin 14 that cooperate with the triangular connecting rods 11. One corner of the triangular connecting rod 11 is connected to the positioning plate 4 through the rotating shaft 12. The triangular connecting rod 11 is provided with a sliding groove 15 symmetrically with respect to the rotating shaft 12. The slide rail plate 7 is provided with a horizontal sliding groove 16. The threaded pin 13 passes through one set of sliding grooves 15 and sliding groove 16 in sequence and is fixedly connected to the lock head 3. The threaded pin 14 passes through another set of sliding grooves 15 and is fixedly connected to the nut block 5.

[0029] In this embodiment, the motor 8 is positioned at the bottom of the positioning plate 4 via the mounting bracket 17.

[0030] In this embodiment, multiple sets of guide rods 18 are installed and fixed between the mounting bracket 17 and the positioning plate 4, and the guide rods 18 slide through the nut block 5 via the bushing 19.

[0031] In this embodiment, the fixing frame 1 is composed of an upper annular top plate 21, a lower annular bottom plate 21, an inner side plate 22, and a vertical plate 23 that is vertically connected to the upper annular top plate 21, the lower annular bottom plate 22, and the inner side plate 22. The locking mechanism 2 is suspended at the bottom of the upper annular top plate 21.

[0032] In this embodiment, the upright plate 23 is provided with a sliding positioning groove 24 for installing the locking mechanism 2. The sliding positioning groove 24 is provided with one or more sets of positioning holes 25. The positioning plate 4 and the upright plate 23 are locked together by a wing screw 26 passing through the positioning hole 25.

[0033] In this embodiment, the positioning plate 4 has multiple sets of positioning holes 27 that cooperate with the wing screw 26. The wing screw 26 can achieve multi-level adjustment of the position of the locking mechanism 2 by connecting to the positioning holes 27 at different positions.

[0034] In this embodiment, the lock head 3 is provided with a waist-shaped hole 28 along the vertical direction to cooperate with the threaded pin 13.

[0035] The working principle of this embodiment is as follows.

[0036] When the motor 8 receives the control signal and rotates, the screw 10 rotates synchronously, causing the nut block 5 to move up and down and the triangular connecting rod 11 to swing left and right, so that the two sets of lock heads 3 set opposite to each other or towards each other, realizing the locking and unlocking action. When the nut block 5 moves to the bottom, it is in the locked state, and when it moves to the top, it is in the unlocked state. If it is necessary to adapt to different specifications of mating bolts 6, it is only necessary to change the shape of the fork of the lock head 3 to match it.

[0037] like Figure 5 The single-sided upright plate 23 shown has two positioning holes 25, as shown. Figure 3 As shown, there are three positioning holes 27 on one side of the positioning plate 4. When the front and rear positions of the locking mechanism 2 are fixed, only one positioning hole 27 needs to be aligned with the positioning hole 25. That is, the front and rear displacement of the locking mechanism 2 can be adjusted in 6 levels. The figure is only an example. The specific adjustment distance and number of levels can be controlled by changing the distance and number of positioning holes 25 and positioning holes 27.

[0038] like Figure 4As shown, the hole for mounting the threaded pin 13 in the lock head 3 is a vertically shaped oblong hole 28. When the lock head 3 is under tension in the locked state, it will move upwards, as shown. Figure 1 As shown, the distance between the lock head 3 and the upper annular top plate 20 is small. When the lock head 3 moves upward, it will be restricted by the upper annular top plate 20, so that the tension it receives is transmitted to the fixed frame 1, thereby protecting the locking mechanism 2.

[0039] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
