Description

Technical Field

[0001] This utility model belongs to the field of tooling and fixture technology, and relates to a lifting tooling for a safe door panel. Background Technology

[0002] With the increasing security demands across various industries, the requirements for the security level of safes are also becoming higher. Following UL safes, CEN safes are gradually becoming the mainstream in the market. After the grouting process, CEN safe doors are removed from the clamps using lifting fixtures. However, traditional lifting fixtures use hooks to hook the parts and lift them. Without specialized lifting fixtures, this can easily cause deformation of the hooked parts, resulting in poor subsequent assembly or appearance. This research aims to create a specialized lifting fixture for convenient, safe, and quick removal of the door panels.

[0003] After grouting, the CEN safe door panel awaits the internal cement to dry. Once dry, the fixing screws of the grouting fixture are removed, and the door panel is lifted from the grouting fixture using a gantry crane or other lifting tools with hooks or lifting fixtures. The stress should be concentrated on thicker areas of the door panel components, avoiding stress concentration at a single point. Conventional hooks tend to concentrate stress, and given the weight of the CEN safe door panel, deformation of the hooked area is likely. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a lifting fixture for safe doors.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A lifting fixture for a safe door panel, comprising:

[0007] The housing has a lifting ring hinged to its upper end and a stop block hinged to its lower end; a guide groove is provided on one side of the housing, an oblong hole is provided on the other side of the housing, and a mounting hole is provided in the middle of the housing.

[0008] A pull pin is slidably installed in a guide groove, and a horizontally protruding handle is provided at the upper end of the pull pin; the lower end of the pull pin can cooperate with a stop block.

[0009] A connecting rod is inserted into a mounting hole, and a spring is provided between the upper end of the connecting rod and the top wall of the mounting hole; a limiting pin is provided on one side of the connecting rod that can cooperate with an oblong hole; the lower end of the connecting rod is hinged by a stop block.

[0010] Preferably, the outer side of the housing is provided with a fixing sleeve for fixing the pull pin.

[0011] Preferably, the lower end of the housing is provided with a clearance groove that can cooperate with the stop block.

[0012] Preferably, the connecting rod is connected to the stop block via a first hinge axis.

[0013] Preferably, the stop block is connected to the housing via a second hinge shaft.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This utility model replaces the conventional hook with a stop block, so that the door panel is subjected to planar force during lifting, thus preventing deformation of the door panel during transportation; through the cooperation of the pull pin and the limit pin, the stop block can be hidden or extended into the housing, which is simple in structure, small in overall size, and easy to use; by changing the components, it can be adapted to the lifting of safe door panels of different specifications.

[0019] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] This embodiment proposes a lifting fixture for a safe door panel, including a housing 1, a stop block 3, a pull pin 7, and a connecting rod 9. The stop block 3 can lock the housing 1 into the lock hole of the door panel; the pull pin 3 is used to move the stop block 3, and the connecting rod 9 is used to return the stop block 3 to its original position.

[0021] like Figures 1-2 As shown, a lifting ring 2 is hinged to the upper end of the housing 1, which is used to connect with external lifting equipment; a stop block 3 is hinged to the lower end of the housing 1. When the housing 1 is inserted into the lock hole of the door panel, the stop block 3 limits the housing 1 when it is extended horizontally, so that the housing 1 can function as a conventional hook.

[0022] A guide groove 4 is provided on one side of the housing 1, an oblong hole 5 is provided on the other side of the housing 1, and a mounting hole 6 is provided in the middle of the housing 1.

[0023] The pull pin 7 is slidably installed in the guide groove 4. The upper end of the pull pin 7 is provided with a horizontally protruding handle 8. The lower end of the pull pin 7 can cooperate with the stop block 3. Pulling the handle 8 downward will push the lower end of the pull pin 7 to rotate the brake block 3, so that the stop block 3 can be retracted into the housing 1, making it easier for the housing 1 to be inserted into the door panel lock hole.

[0024] The connecting rod 9 is inserted into the mounting hole 6. A spring 10 is provided between the upper end of the connecting rod 9 and the top wall of the mounting hole 6. The spring 10 gives the connecting rod 9 a downward pressure away from the top wall of the mounting hole 6.

[0025] A limiting pin 11 is provided on one side of the connecting rod 9, which can cooperate with the oblong hole 5. The limiting pin 11 can move up and down within the oblong hole 5.

[0026] The lower end of the connecting rod 9 is hinged by the stop block 3. When the stop block 3 is retracted into the housing 1, the connecting rod 9 is pushed up, the spring 10 contracts, and the limit pin 11 moves upward. When the housing 1 is inserted into the lock hole of the door panel, the pull pin 7 is released, the spring 10 returns to its original position, the connecting rod 9 drives the stop block 3 to return to its original position, and when the limit pin 11 is located at the lowest end of the oblong hole 5, the stop block 3 is in a horizontal position.

[0027] Furthermore, a fixing sleeve 12 for fixing the pull pin 7 is provided on the outer side of the housing 1, and the fixing sleeve 12 prevents the pull pin 7 from running out of the guide groove 4.

[0028] Furthermore, the lower end of the housing 1 is provided with a relief groove 13 that can cooperate with the stop block 3, and the relief groove 13 facilitates the stop block 3 to be retracted into the housing 1.

[0029] Furthermore, the connecting rod 9 is connected to the stop block 3 via the first hinge shaft 14, and the first hinge shaft 14 prevents the stop block 3 and the connecting rod 9 from interfering with each other.

[0030] Furthermore, the stop block 3 is connected to the housing 1 via a second hinge shaft 15, which allows the stop block 3 to rotate within the housing 1.

[0031] Working principle: When using this utility model, first pull down the pull pin 7. The lower end of the pull pin 7 pushes the stop block 3 downward. The stop block 3 rotates along the second hinge shaft 15. One end of the stop block 3 is inserted into the relief groove 13 of the housing 1, and the other end hangs down. At this time, the housing 1 can pass through the lock hole on the door panel. Then, release the pull pin 7. The spring 10 pushes the connecting rod 9. The connecting rod 9 drives the stop block 3 to reset. When the limit pin 11 is at the lowest end of the oblong hole 5, the stop block 3 is in a horizontal position. Connect the lifting ring 2 to the lifting equipment to lift the door panel.

[0032] It is understood that the above embodiments are merely exemplary models used to illustrate the principles of this utility model, and this utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
