[0002] With the development of the industry, the types, different performances and functions of industrial boxes or cabinets have changed greatly. The most obvious point is that the environmental requirements for the inside of the box or cabinet are getting higher and higher. For example, some require a sealing function, and there are requirements such as high temperature and high pressure inside some boxes. If the supporting door locks are used with the existing technical solutions, these requirements may not be met.

[0003] Subsequently, there appeared a tightening handle, which drives a tightening buckle to lock by the handle, so that the door body obtains a tightening lock effect, so that the door body can achieve a leak-proof effect after being sealed, especially for preventing the leakage of hot air or cold air inside the box or cabinet. Usually, an anti-detachment lock buckle will be added after the tightening handle realizes the tightening connection. The traditional anti-detachment lock buckle uses a mechanical lock, which is manually opened and closed and cannot meet the requirements of automatic electric control, so there are limitations in application, and further improvement is needed.

The electric telescopic pin is arranged on the handle and extends and retracts in a set direction, and the electric telescopic pin is also connected to a manual unlocking member, so that in the case of power failure, the electric telescopic pin can be driven to withdraw from the lock buckle through the manual unlocking member; the clamping member is arranged on the tightening seat and is used for cooperating with the electric telescopic pin to lock when it extends.

[0009] In the above scheme, further, the electric telescopic pin is an electromagnetic telescopic rod, and the electric telescopic pin is driven to extend and retract by magnetic force; the clamping member is a pressing rod protruding on the tightening seat, the clamping member protrudes in the same direction as the tightening protrusion, and the extending direction of the electric telescopic pin is perpendicular to the protruding direction of the clamping member; in the locked state, the electric telescopic pin extends and is stuck under the clamping member, so that the tightening groove and the tightening protrusion remain in the locked state.

[0010] The above scheme is further that the telescopic end of the electric telescopic pin is provided with an axial cutting groove, and the axial cutting groove is connected to the manual unlocking piece. The manual unlocking piece is a lever structure assembled on the handle and suspended in a vertical manner. The resistance end of the manual unlocking piece is inserted into the axial cutting groove, and the force-applying end of the manual unlocking piece extends from the handle so that the force-applying end of the manual unlocking piece can be manually pulled to make the manual unlocking piece drive the electric telescopic pin to exit the lock.

[0020] It should be noted that in the description of the present utility model, the terms indicating directions or positional relationships such as "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0021] Referring to Figures 1 to 5 As shown, it is a schematic diagram of a preferred embodiment of the present utility model. The present utility model relates to a tightening handle, especially for products such as medical boxes and environmental test boxes, to obtain a tightening effect when the door body is closed. The tightening handle has a fixed seat 1, a handle 2 and a tightening seat 3. During implementation, the fixed seat 1 is installed on the door body, and the tightening seat 3 is installed on the box body. The door body moves relative to the box body for opening and closing. The handle 2 is installed on the fixed seat 1 and can rotate relative to it. There is a tightening groove 21 on the handle 2. After the door body is closed, the tightening groove 21 can be hooked onto the tightening protrusion 31 of the tightening seat 3 following the rotation of the handle 2 to achieve tightening and additional force, and a locked state is constructed. In this embodiment, the tightening protrusion 31 is in the form of a roller. The tightening groove 21 uses the arc-shaped curved side wall to contact the tightening protrusion 31 and form extrusion and pulling, so that the door body leans towards the box body to obtain a tightly closed effect. A first anti-disengagement locking system is also provided between the handle 2 and the tightening seat 3 to limit the rotation of the handle 2 and prevent accidental loosening after the tightening connection between the tightening groove 21 and the tightening protrusion 31, thereby improving the use efficiency of the tightening handle. The first anti-disengagement locking system at least includes an electric telescopic latch 22 and a locking member 32. The electric telescopic latch 22 is arranged on the handle 2 and extends and retracts in a set direction, and the electric telescopic latch 22 is also connected to a manual unlocking member 23, so that in the case of power failure, the electric telescopic latch 22 can be driven by the manual unlocking member 23 to withdraw from the lock, avoiding the situation where the lock cannot be opened when the power is off; the locking member 32 is arranged on the tightening seat 3 and is used to cooperate with the electric telescopic latch 22 when it extends to lock.

[0022] The present embodiment further provides that the electric telescopic bayonet 22 is an electromagnetic telescopic rod, and the electric telescopic bayonet is driven to extend and retract by magnetic force, specifically, the electromagnetic coil generates a magnetic field when it is energized, and the electric telescopic bayonet 22 is driven by magnetic force, and the positive and negative changes of the current can be used to realize the positive and negative magnetic fields when the electromagnetic coil is energized, thereby driving the electric telescopic bayonet 22 to extend and retract. The working principle of the electromagnetic coil is a prior art and will not be described in detail here. The clamp 32 is a pressure rod protruding from the clamp seat 3, and the clamp 32 and the clamp protrusion 31 protrude in the same direction, and the extension direction of the electric telescopic bayonet is perpendicular to the protrusion direction of the clamp 32; in the locked state, the electric telescopic bayonet 22 extends and is stuck on the lower side of the clamp 32, limiting the rotation of the handle, so that the clamp groove 21 and the clamp protrusion 31 remain in a locked state.

[0023] Figure 5 As shown, the telescopic end of the electric telescopic bayonet 22 is provided with an axial cut groove 221, and the axial cut groove 221 is connected to the manual unlocking member 23. The manual unlocking member 23 is a lever structure assembled on the handle 2 and suspended. The resistance end of the manual unlocking member 23 is inserted into the axial cut groove 221, and the force end of the manual unlocking member 23 extends from the handle 2, so that the force end of the manual unlocking member 23 is manually pulled, so that the manual unlocking member 23 drives the electric telescopic bayonet 22 to exit the lock. When the electric telescopic bayonet 22 telescopes under electric control, the resistance end of the manual unlocking member 23 remains inserted into the axial cut groove 221, so that in the case of power failure, the force end of the manual unlocking member 23 can be pulled, so that the manual unlocking member 23 can drive the electric telescopic bayonet 22 to exit the lock, so that the handle can be turned to perform the locking action, which can not only meet the electric control, but also solve the problem that the electric telescopic bayonet 22 cannot be unlocked when the power is accidentally cut off (power failure). In this embodiment, the manual unlocking member 23 is further connected to the handle 2 through the mounting seat 24, the manual unlocking member 23 is hingedly connected to the mounting seat 24, and the mounting seat 24 is screwed to the handle 2, so that the manual unlocking member 23 is positioned and installed, and can cooperate with the electric telescopic bayonet 22. The handle 2 is also provided with an avoidance hole 25, and the force-applying end of the manual unlocking member 23 extends from the avoidance hole 25. The structure is simple, the manufacture and assembly are simple, and the operation is also convenient.

[0024] Figure 1 , 2As shown in FIGS. 3, in this embodiment, the handle 2 is connected to the fixed seat 1 through a rotating shaft 4, enabling the handle 2 to rotate around the central axis of the rotating shaft 4. A second anti-disengagement locking system is further provided between the handle 2 and the fixed seat 1. The second anti-disengagement locking system at least includes a mechanical lock 5. The mechanical lock 5 is positioned on the handle 2 and is provided with a locking tongue 51 extending towards the fixed seat 1. The locking tongue 51 extends and inserts into a preset locking hole 11 of the fixed seat 1, restricting the rotation of the handle and keeping the tightening groove 21 and the tightening protrusion 31 in a locked state. The second anti-disengagement locking system can be optionally used together with the first anti-disengagement locking system to obtain a dual-locking effect.

[0025] The tightening handle of the present utility model has an electric telescopic pin locking buckle, realizing electric drive, meeting the requirements of intelligent control, improving the use efficiency and convenience of the tightening handle, promoting the functional development and exploitation of the tightening handle, and conforming to the needs of the times. It has a compact structure, good performance, is convenient for assembly and use, and has a long service life.

[0026] Although the preferred specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, the present utility model should not be limited to the exact same structure and operation as described above and shown in the drawings. For those skilled in the art of this technology, many equivalent improvements and changes can be made to the above embodiments through logical analysis, reasoning, or limited experiments without exceeding the concept and scope of the present utility model. However, these improvements and changes should all fall within the scope of protection required by the present utility model.
