[0031] In the description of the present invention, the meaning of several is one or more, the meaning of multiple is two or more, and understandings such as greater than, less than, exceeding, etc. do not include the present number, and understandings such as above, below, within, etc. include the present number. If there is a description of first and second, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0032] In the description of the present invention, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0033] It can be understood that with reference to Figures 1 to 12, A safe handle of the present utility model includes a square bar 200 and two sets of rotating components 100. The rotating component 100 includes a mounting base 110 and a handle 120. The mounting base 110 is provided with a mounting hole 111. The handle 120 is provided with a connecting portion 121. The connecting portion 121 is rotatably connected to the mounting hole 111. The connecting portion 121 is integrally formed with a limiting block 122. The side wall of the mounting hole 111 is provided with an arc-shaped limiting groove 112 along the circumferential direction. The limiting block 122 can slide in the arc-shaped limiting groove 112, and the limiting block 122 can abut against the side wall of the arc-shaped limiting groove 112 to limit the rotation of the connecting portion 121. The connecting portion 121 is provided with a first jack 123 along the axial direction. The two ends of the square bar 200 are respectively inserted into the first jacks 123 of the two connecting portions 121. The cross-sectional side length of the square bar 200 is 11 mm.

[0034] When the handle 120 is rotated, the connecting portion 121 drives the limiting block 122 to rotate, so that the limiting block 122 slides in the arc-shaped limiting groove 112. By abutting the limiting block 122 against the side wall of the arc-shaped limiting groove 112 to limit the rotation of the connecting portion 121, the rotation angle of the handle 120 can be positioned. Since the limiting block 122 and the connecting portion 121 are integrally formed, the structural strength of the limiting block 122 and the connecting portion 121 can be improved, thereby increasing the torque of the safe handle. At the same time, by setting the cross-sectional side length of the square bar 200 to 11 mm, the radial load and axial load of the safe handle can be increased, thereby reducing the possibility of deformation and damage of the safe handle, prolonging the service life of the safe handle, and further improving the use safety of the safe.

[0035] It should be noted that the torque of the safe handle of the present utility model reaches more than 125 N·m, the radial load reaches more than 1500 N, and the axial load reaches more than 2500 N. The torque, radial load and axial load are all higher than those of the existing safe handles.

[0036] The limiting block 122 and the connecting portion 121 are integrally formed by casting, which can improve the structural strength to reduce the risk of deformation and damage.

[0037] It can be understood that with reference to Figures 3 to 7 , the rotating component 100 further includes an arc-shaped positioning block 130. The arc-shaped positioning block 130 is movably sleeved on the connecting portion 121. The arc-shaped positioning block 130 can slide in the arc-shaped limiting groove 112, and the two ends of the arc-shaped positioning block 130 can respectively abut against the side wall of the arc-shaped limiting groove 112 and the limiting block 122 to limit the rotation of the connecting portion 121. When the connecting portion 121 drives the limiting block 122 to rotate, the limiting block 122 can abut against one end of the arc-shaped positioning block 130 and drive the arc-shaped positioning block 130 to slide in the arc-shaped limiting groove 112 until the other end of the arc-shaped positioning block 130 abuts against the side wall of the arc-shaped limiting groove 112 to limit the rotation of the connecting portion 121, thereby positioning the rotation angle of the handle 120.

[0038] It should be noted that by adjusting the curvature value of the arc-shaped positioning block 130 to adjust the curvature difference between the arc-shaped positioning block 130 and the arc-shaped limiting groove 112, the sliding range of the limiting block 122 in the arc-shaped limiting groove 112 can be adjusted, and then the rotation angle range of the handle 120 can be adjusted, which can improve the applicability of the safe handle, and according to the rotation angle range requirements, it is only necessary to replace the arc-shaped positioning block 130 with different curvatures, without replacing the mounting base 110, which can improve the convenience of adjustment.

[0039] The arc-shaped positioning block 130 can be made of stainless steel, and the axial thickness of the arc-shaped positioning block 130 is 3.8 mm, and the radial thickness of the limit block 122 is 2.5 mm, which can improve the structural strength of the arc-shaped positioning block 130, thereby improving the torsion of the safe handle.

[0040] It is understandable that, referring to Figure 2 , Figure 3 and Figure 8 The rotating assembly 100 further includes an annular clamping block 140, which is threadedly connected to the end of the connecting portion 121, and the annular clamping block 140 can abut against the mounting seat 110 to limit the axial movement of the connecting portion 121. The annular clamping block 140 abuts against the mounting seat 110 to limit the axial movement of the connecting portion 121, which can reduce the axial shaking of the handle 120, thereby improving the rotation stability of the handle 120, and because the annular clamping block 140 is threadedly connected to the end of the connecting portion 121, the annular clamping block 140 and the connecting portion 121 can be separated by twisting the annular clamping block 140, which facilitates the disassembly, assembly and replacement of the annular clamping block 140.

[0041] Specifically, refer to Figure 2 , Figure 3 and Figure 8 The mounting seat 110 is provided with a mounting groove 113, the mounting groove 113 is connected to the mounting hole 111, the annular clamping block 140 is embedded in the mounting groove 113, and the shape of the mounting groove 113 matches the shape of the annular clamping block 140. Since the annular clamping block 140 is embedded in the mounting groove 113, and the shape of the mounting groove 113 matches the shape of the annular clamping block 140, the radial movement of the annular clamping block 140 can be limited by the side wall of the mounting groove 113 abutting against the outer side wall of the annular clamping block 140, thereby reducing the radial shaking of the connecting portion 121 and improving the rotation stability of the handle 120.

[0042] It should be noted that, by the annular clamping block 140 abutting against the bottom wall of the mounting groove 113 , the axial movement of the connecting portion 121 can be limited to reduce the axial shaking of the handle 120 , thereby improving the rotation stability of the handle 120 .

[0043] It is understandable that, referring to Figures 2 to 5, Figures 9 to 10 The rotating assembly 100 further includes a torsion spring 150. The torsion spring 150 is sleeved on the connecting portion 121. Two ends of the torsion spring 150 are respectively connected to the connecting portion 121 and the mounting base 110. The torsion spring 150 is used to drive the connecting portion 121 to rotate and reset. When the connecting portion 121 rotates, it can drive one end of the torsion spring 150 to rotate. Since the other end of the torsion spring 150 is connected to the mounting base 110, the torsion spring 150 is elastically twisted and deformed. When the handle 120 is released, the torsion spring 150 elastically recovers, and the connecting portion 121 is driven to rotate and reset quickly by the elastic force of the torsion spring 150, which can improve the reset efficiency of the handle 120.

[0044] Specifically, referring to Figures 2 to 5 , Figures 9 to 10 , the connecting portion 121 is provided with a second jack 124, and a clamping groove 114 is provided on the side wall of the mounting hole 111. Two ends of the torsion spring 150 are respectively provided with a first positioning portion 151 and a second positioning portion 152. The first positioning portion 151 extends along the axial direction of the torsion spring 150, and the second positioning portion 152 extends radially outward along the torsion spring 150. The first positioning portion 151 is inserted into the second jack 124, and the second positioning portion 152 is clamped into the clamping groove 114. Since two ends of the torsion spring 150 are respectively provided with the first positioning portion 151 and the second positioning portion 152, the first positioning portion 151 extends along the axial direction of the torsion spring 150, and the second positioning portion 152 extends radially outward along the torsion spring 150. By inserting the first positioning portion 151 into the second jack 124 and clamping the second positioning portion 152 into the clamping groove 114, the installation and positioning of the torsion spring 150 can be completed. And by pulling out the first positioning portion 151 from the second jack 124 and pulling out the second positioning portion 152 from the clamping groove 114, the disassembly of the torsion spring 150 can be completed, so that the disassembly, installation and replacement of the torsion spring 150 can be facilitated.

[0045] It can be understood that referring to Figure 4 , Figure 11 and Figure 12 , the two ends of the square bar 200 are provided with rounded corners 210. By providing the two ends of the square bar 200 with rounded corners 210, the rounded corners 210 are used to guide the end of the square bar 200 to be inserted into the first jack 123, which can improve the convenience and accuracy of the insertion of the square bar 200, and can reduce the collision and wear between the square bar 200 and the connecting portion 121.

[0046] It can be understood that referring to Figure 4 , Figure 11 and Figure 12, the shape of the first jack 123 matches the shape of the square bar 200, and an avoidance groove 125 is axially formed on the side wall of the first jack 123. By axially forming the avoidance groove 125 on the side wall of the first jack 123, the contact area between the square bar 200 and the side wall of the first jack 123 can be reduced, thereby reducing the frictional resistance during the insertion process of the square bar 200, so as to improve the smoothness of the insertion of the square bar 200.

[0047] It can be understood that, referring to Figure 1 , the handle 120 is provided with a hand-held portion 126. Along the length direction of the hand-held portion 126, the width of the hand-held portion 126 gradually decreases in the direction away from the connecting portion 121. Since along the length direction of the hand-held portion 126, the width of the hand-held portion 126 gradually decreases in the direction away from the connecting portion 121, it can adapt to the gripping force application of different hand sizes, thereby facilitating the user to apply force to rotate the handle 120.

[0048] It can be understood that, referring to Figure 5 , the mounting seat 110 is provided with three connecting holes 115. The three connecting holes 115 are evenly arranged at intervals along the circumferential direction of the mounting seat 110. The connecting holes 115 are used for passing bolts to fixedly connect the mounting seat 110 to the safe door. By passing bolts through the connecting holes 115 and using the bolts to fixedly connect the mounting seat 110 to the safe door, the convenience of installing the mounting seat 110 can be improved. And since the mounting seat 110 is provided with three connecting holes 115 and the three connecting holes 115 are evenly arranged at intervals along the circumferential direction of the mounting seat 110, through the bolts evenly connected at intervals along the circumferential direction of the mounting seat 110, the force can be dispersed circumferentially to improve the connection structure strength, thereby improving the stability of the position of the mounting seat 110.

[0049] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention.
