Description

Technical Field

[0001] The present application relates to the technical field of safes, and more particularly to a safe door panel anti-falling mechanism and a safe containing the same. Background Art

[0002] A safe is a tool for storing valuables and important documents. Currently, the structure of a safe includes a box body, on which a door frame and a door panel are arranged, wherein the door frame and the door panel are assembled by a structure similar to a hinge, so that the door panel can be opened and closed relative to the door frame. This hinge-like structure generally includes a shaft and a shaft sleeve, wherein the shaft is fixed on the door panel or the door frame, and the shaft sleeve is fixed on the other side, and the two are fitted together to realize the rotation of the door panel relative to the door frame. The shaft and the shaft sleeve can be axially positioned by screws. However, this screw positioning method has certain disadvantages: first, the screws need to be screwed, and the operation time is long. In addition, the screws are prone to loosening. Once loosened, if the safe is inverted, it may cause the door panel to loosen and affect the use. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the present application provides a safe door panel anti-falling-off mechanism which can effectively prevent the door panel from falling off and being convenient and quick to disassemble and install.

[0004] In order to solve the above technical problems, the technical solution adopted in the present application is: a safe door panel anti-falling mechanism, which includes a safe door panel and a safe door frame, the safe door panel and the safe door frame are connected to each other by at least one group of door panel anti-falling structures, the door panel anti-falling structure includes a hinge shaft, a hinge sleeve and a pin, the hinge shaft is arranged on the safe door panel or the safe door frame, the hinge sleeve is arranged on the safe door panel or the safe door frame corresponding to the hinge shaft, the hinge sleeve is sleeved on the hinge shaft and can rotate circumferentially relative to the hinge shaft; a slot is arranged on the hinge shaft, the slot is located above or below the hinge sleeve after sleeved, and the pin is clamped in the slot for axial limitation of the hinge sleeve.

[0005] By adopting the above structure, the present application sets a door panel anti-falling-off structure between the safe door panel and the safe door frame. The anti-falling-off structure can axially limit the hinge sleeve after being installed through the cooperation between the card slot and the card pin. Even if the safe is inverted, the hinge sleeve can be prevented from being separated from the hinge shaft due to the setting of the card pin, thus preventing the door panel from being separated from the door frame; the structure of the card pin and the card slot being mutually engaged and limited is simple to operate and only requires the card pin to be inserted into the card slot to complete the operation. Therefore, the operation is simpler and more convenient, and the disassembly process only requires the card pin to be removed from the card slot; it effectively saves time, improves assembly efficiency, and can also prevent the door panel from falling off, and prevent the use state of the safe from being affected during the inversion process.

[0006] Furthermore, the slot is radially concave along the circumference of the hinge axis, and the pin is engaged in the slot and can rotate along the circumference of the slot. With this structure, the pin can be rotated to a hidden position after assembly to avoid it from being accidentally touched and causing it to fall out of the slot.

[0007] Furthermore, an opening is provided on the bayonet, and the width of the opening is smaller than the outer diameter of the slot. With this structure, the bayonet can be connected to the slot through the opening by deformation force, and then the opening can be restored to achieve a stable connection with the slot, preventing the bayonet from detaching.

[0008] Furthermore, a force-applying portion is provided on the bayonet, and the force-applying portion is arranged opposite to the opening. With this structure, when installing or removing the bayonet, it is easier to generate force on the bayonet by applying force to the force-applying portion, so that it is more convenient to engage with or disengage from the slot.

[0009] Furthermore, after the hinge sleeve is sleeved on the hinge shaft and the bayonet pin is engaged with the slot, a gap is provided between the bayonet pin and the hinge sleeve. With this structure, under normal use, the hinge sleeve can avoid pushing and rubbing against the bayonet pin, thereby avoiding damage to the bayonet pin.

[0010] Furthermore, a hinge plate is provided on the safe door panel, the hinge sleeve is fixed on the hinge plate, and the hinge shaft is fixed on the safe door frame; the hinge sleeve is circumferentially rotatable in the hinge shaft so that the safe door panel can rotate relative to the safe door frame; with the above structure, the transition setting of the hinge plate can realize the rotation of the door panel relative to the door frame over a larger range of angles.

[0011] Furthermore, a hinge plate is provided on the safe door panel, and the hinge shaft is fixed on the hinge plate; the hinge sleeve is fixed on the safe door frame; the hinge sleeve is circumferentially rotatable in the hinge shaft so that the safe door panel can rotate relative to the safe door frame; with the above structure, the fixed positions of the sleeve and the shaft can be interchanged, and the door panel can still be rotated relative to the door frame, and the fixed positions of the sleeve and the shaft can be adjusted as needed.

[0012] Furthermore, the outer diameter of the bayonet is smaller than the outer diameter of the hinge sleeve; adopting this structure can prevent the bayonet from being accidentally hit due to its large size, and can also reduce its occupied space and avoid limiting the rotation angle of the door panel.

[0013] Furthermore, the bayonet is a plastic part, and the bayonet is made of plastic material, which can save costs and facilitate processing and molding.

[0014] The present application also provides a safe, which contains the safe door panel anti-falling mechanism mentioned above in the present application. A safe adopting this structure will not cause the door panel and door frame to fall off even when it is inverted, and the structure is easy to install and disassemble and convenient to operate.

The latch 303 can be made of a material with deformation recovery force, such as plastic or metal.

[0029] As attached Figure 1-3As shown in Figures 5 and 7, the bayonet 303 described in the present application is provided with a force-applying portion 306, and the force-applying portion 306 is arranged opposite to the opening 305; that is, the force-applying portion 306 is arranged on one side along the lateral extension direction of the bayonet 303, and the opening 305 is arranged on the other side thereof; specifically, the force-applying portion 306 is a lateral extension structure arranged tangent to the outer wall of the bayonet 303, so that there is a space between the outer wall of the bayonet 303 and the force-applying portion 306 that is convenient for gripping and is conducive to applying force; with this structure, when installing or removing the bayonet, by applying force to the force-applying portion, it is easier to generate a force on the bayonet 303, so that it is more convenient to engage with or disengage from the slot 304; and the setting of the force-applying portion makes it easier to rotate the bayonet 303 by gripping.

[0030] As attached Figure 4 , 6 As shown, after the hinge sleeve 302 described in the present application is sleeved on the hinge shaft 301 and the bayonet 303 is engaged in the slot 304, a gap is provided between the bayonet 303 and the hinge sleeve 302. With this structure, under normal use, the hinge sleeve 302 can be prevented from pushing and rubbing against the bayonet 303, thereby avoiding damage to the bayonet 303.

[0031] As attached Figure 1-2 As shown, the safe door panel 1 described in the present application is provided with a hinge plate 4, and the hinge sleeve 302 is fixed on the hinge plate 4; the hinge shaft 301 is fixed on the safe door frame 2; the hinge sleeve 302 is circumferentially rotatable and sleeved in the hinge shaft 301, so that the safe door panel 1 can rotate relative to the safe door frame 2; with the above structure, the transition setting of the hinge plate 4 can realize the rotation of the door panel 1 relative to the door frame 2 in a larger range of angles; specifically, the safe door panel 1, the safe door frame 2, the hinge shaft 301 and the hinge sleeve 302 of the present application can be metal parts, and the above-mentioned hinge plate 4 and the door panel 1 are connected by welding, the hinge sleeve 302 and the hinge plate 4 are also connected by welding, and the hinge shaft 301 and the safe door frame 2 are also connected by welding.

[0033] As attached Figure 7 The outer diameter of the latch 303 described in the present application is smaller than the outer diameter of the hinge sleeve 302; adopting this structure can prevent the latch 303 from being accidentally hit due to its large size, and can also reduce its occupied space and avoid limiting the rotation angle of the door panel 1.

[0034] As an example, the bayonet 303 described in the present application is a plastic part, that is, the bayonet 303 structure is made of plastic material. The preparation process of the plastic part structure is simple and the material cost is low, which effectively reduces the cost compared with the existing screw structure.

A safe adopting this structure will not cause the door panel and door frame to separate even when inverted, and the structure is easy to install and disassemble and convenient to operate.

[0036] The specific working principle and process of the safe door panel anti-falling mechanism mentioned in the present application are as follows: Figure 1-7 , a hinge plate 4 is welded on one side of the door panel 1 of the safe (one hinge plate 4 is welded on the upper and lower sides of one side wall of the door panel 1), and then a hinge sleeve 302 is welded on the hinge plate 4; a hinge shaft 301 is welded on one side of the door frame 2 (a reinforcing plate can be welded on the side wall of the door frame, and then the hinge shaft 301 is welded on the reinforcing plate body), and then the hinge sleeve 302 is sleeved on the hinge shaft 301 to realize the rotatable connection between the door panel 1 and the door frame 2, and then the bayonet 3 The latch 303 is then engaged with the hinge shaft 302, and the hinge shaft 302 is locked in the locking groove 304. The entire assembly can be completed. Since the latch 303 is partially inserted into the locking groove 304 and partially placed outside the locking groove 304, if the safe is inverted, the hinge shaft sleeve 302 will slide towards the latch 303 until it abuts against the latch 303. At this time, the latch 303 can limit the hinge shaft sleeve 302 to prevent it from being separated from the hinge shaft 301, thereby preventing the door panel 1 from being separated from the door frame 2. For details, refer to the attached Figure 1-2 In the present application, a set of door panel anti-falling structures 3 (i.e., a complete set of door panel anti-falling structures) is set between the door panel 1 and the door frame 2, and another set of simple shaft sleeve and shaft structures is also set; the two are arranged up and down, and the door panel anti-falling effect can be achieved through a set of door panel anti-falling structures 3. Of course, multiple sets can also be set, and the number is allocated according to the size and weight of the door panel; the present application sets the above-mentioned specific door panel anti-falling structure on the safe for the first time. This structure is easy to install and disassemble, saves time, and has a good limiting effect, which can effectively avoid the door panel detachment caused by the inversion process of the safe.
