Description

Technical Field

[0001] This utility model relates to the field of mechanical hardware technology, specifically a two-way locking structure. Background Technology

[0002] Locking structures are suitable for applications requiring rapid locking / unlocking, such as industrial equipment (e.g., robotic arm grippers), portable instruments (medical testing equipment, camera stands), outdoor gear (folding tools, sports equipment), and automotive parts (battery holders). However, existing locking structures still have the following shortcomings in use:

[0003] In the existing technology, traditional locking structures often have problems such as cumbersome operation (requiring tools or the use of both hands), uneven locking force that is easy to loosen, concentrated pressure on the screw that is easy to deform, and decreased stability after repeated disassembly, resulting in unsatisfactory performance. Summary of the Invention

[0004] This invention provides a bidirectional locking structure to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a two-way locking structure, including a latch and a locking handle, wherein the two ends of the latch are opposite to the two ends of the locking handle and are connected by a rotating fastener;

[0006] The rotating clamp includes an inner rotating clamp and an outer rotating clamp that engage with a ramp surface. When the outer rotating clamp is driven to rotate...

[0007] Furthermore, double-headed threaded screws are threaded through both ends of the latch, both ends of the locking handle, and the interior of the rotating clip.

[0008] Furthermore, each of the two opposite sides of the latch is provided with a bowl-shaped groove, and the inner rotating fastener is installed inside the bowl-shaped groove.

[0009] Furthermore, a limiting groove is provided inside the bowl-shaped groove, and an inner limiting block is provided on one side of the inner rotating fastener, with one end embedded inside the limiting groove.

[0010] Furthermore, the opposite surfaces at both ends of the locking handle are provided with slots.

[0011] Furthermore, one side of the external rotating card is provided with an external limiting block that is embedded inside the card slot.

[0012] Furthermore, both ends of the locking handle are provided with a bowl-shaped groove.

[0013] Furthermore, both ends of the double-ended threaded screw are threaded with cup-shaped nuts.

[0014] Furthermore, the bowl-shaped nut is embedded inside the bowl-shaped groove, and a knob is provided on one side of the bowl-shaped nut.

[0015] Furthermore, the two ends of the latch, the two ends of the locking handle, the rotating clip, and the cup-shaped nut are all coaxially arranged.

[0016] Compared with the prior art, the present invention provides a bidirectional locking structure, which has the following beneficial effects:

[0017] This two-way locking structure utilizes the wedge effect of the inner and outer rotating clamps' inclined surfaces to achieve quick one-handed operation of "locking down and releasing up." When locking, the inclined surface slides from the bottom to the top of the slope, generating a continuously increasing clamping force to ensure the item remains stable and secure. When releasing, the inclined surfaces naturally separate, allowing for easy release without effort. The double-ended threaded screw, due to the pressure distribution caused by the inclined transmission, is not easily deformed or bent over long-term use, exhibiting high durability. The overall structure is compact, with uniform locking force, ensuring stable and reliable operation even after repeated use. It is also easy to maintain, making it particularly suitable for equipment fixing scenarios that require frequent disassembly and assembly. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7 This utility model discloses a two-way locking structure, including a locking buckle 1 and a locking handle 2. The two ends of the locking buckle 1 are opposite to the two ends of the locking handle 2 and are connected by a rotating fastener 3.

[0028] The rotating locking component 3 includes an inner rotating locking component 31 and an outer rotating locking component 32 that cooperate through a ramp surface 33. When the outer rotating locking component 32 is driven to rotate, its ramp surface 33 pushes against the ramp surface 33 of the inner rotating locking component 31, forcing the two ends of the latch 1 to move in opposite directions to achieve bidirectional locking or unlocking.

[0029] The inner rotating clamp 31 and the outer rotating clamp 32 are both provided with slopes 33 with equal sides and opposite inclination directions on their opposite surfaces, generating a wedge effect (slope transmission principle). When the outer rotating clamp 32 is driven to rotate by the locking handle 2, its slope 33 pushes against the slope 33 of the inner rotating clamp 31. The slope 33 separates or closes along the direction perpendicular to the side. When the two ends of the locking handle 2 are limited by the cup-shaped nut 5, the downward flip of the locking handle 2 will drive the outer rotating clamps 32 at both ends to push against the inner rotating clamp 31, so that the two inner rotating clamps 31 push against the two ends of the latch 1 and move relative to each other to hold the items inside.

[0030] Specifically, the two ends of the latch 1, the two ends of the locking handle 2, and the interior of the rotating clip 3 are all fitted with double-headed threaded screws 4.

[0031] In this embodiment, the inclined surface 33 of the inner rotating clamp 31 and the outer rotating clamp 32 are designed to fit together, which reduces the pressure on the double-headed screw and ensures that the screw does not deform or bend after long-term use.

[0032] Specifically, the two opposite sides of the latch 1 are provided with a bowl-shaped groove 11, the inner rotating fastener 31 is installed inside the bowl-shaped groove 11, the inner side of the bowl-shaped groove 11 is provided with a limiting groove 12, and one side of the inner rotating fastener 31 is provided with an inner limiting block 311 with one end embedded in the limiting groove 12.

[0033] In this embodiment, the limiting groove 12 and the inner limiting block 311 are configured to synchronize the movement of the inner rotating locking piece 31 and the end of the latch 1. The latch 1 is also provided with a fixing hole 13. When the latch 1 is limited by the screw sleeve on the item through the fixing hole 13, refer to... Figure 7When the user flips the locking handle 2 downwards, the locking handle 2 causes the outer rotating latch 32 to rotate. The slope surface 33 of the outer rotating latch 32 switches from contact between the foot of the slope and the top of the slope surface 33 of the inner rotating latch 31 to contact between the tops of the slopes. During this process, a force is generated that pushes against the inner rotating latch 31, causing the inner rotating latch 31 to cause the two ends of the lock 1 to grip the item tightly. Conversely, refer to [the relevant documentation]. Figure 6 The user flips the locking handle 2 upwards, causing the outer rotating clip 32 to disengage from the inner rotating clip 31, causing the two ends of the latch 1 to spring back and release the item.

[0034] Specifically, the locking handle 2 has slots 21 on both opposite sides, and the outer rotating clip 32 has an outer limiting block 321 embedded in the slot 21 on one side.

[0035] In this embodiment, the outer rotating clamp 32 is linked with the locking handle 2 by cooperating with the slot 21 through the outer limiting block 321. The outer limiting block 321 is inserted into the slot 21 and the two ends of the outer rotating clamp 32 and the locking handle 2 are coaxial. Then the outer rotating clamp 32 and the inner rotating clamp 31 are assembled together through the ramp surface 33.

[0036] Specifically, both ends of the locking handle 2 are provided with a bowl-shaped groove 22, and both ends of the double-ended threaded rod 4 are threaded with a bowl-shaped nut 5. The bowl-shaped nut 5 is embedded in the bowl-shaped groove 22 and a knob 51 is provided on one side of the bowl-shaped nut 5. Both ends of the latch 1, both ends of the locking handle 2, the rotating clip 3 and the bowl-shaped nut 5 are all coaxially arranged.

[0037] In this embodiment, after the outer rotating clip 32 and the inner rotating clip 31 are assembled, the two ends of the latch 1, the two ends of the locking handle 2, the rotating clip 3, and the cup-shaped nut 5 are all coaxially arranged and inserted into the double-ended threaded rod 4, so that the threaded portions at both ends of the double-ended threaded rod 4 extend to the two cup-shaped grooves 22 respectively. Finally, the cup-shaped nut 5 is put on both ends of the double-ended threaded rod 4, and the cup-shaped nut 5 is screwed into the inside of the cup-shaped groove 22 by rotating the knob 51.

[0038] In summary, this bidirectional locking structure, through the wedge effect of the inclined surfaces of the inner rotating clamp 31 and the outer rotating clamp 32, achieves a quick one-handed operation of "locking down and releasing up". When locking, the inclined surface 33 slides from the foot of the slope to the top, generating a continuously increasing clamping force to ensure that the item is stable and does not loosen. When releasing, the inclined surfaces separate naturally, and the item can be released without effort. The double-ended threaded screw 4 is not easily deformed or bent due to the pressure distribution of the inclined transmission, and is highly durable. The overall structure is compact, the locking force is uniform, and it is stable and reliable in repeated operation. It is easy to maintain and is particularly suitable for equipment fixing scenarios that require frequent disassembly and assembly.
