Description

Technical Field

[0001] This utility model relates to the field of electronic equipment and communication cabinet technology, and in particular to a sliding damping stop door device for frame cabinets. Background Technology

[0002] With the technological advancements in electronic equipment and communication cabinets, there has been a growing trend towards higher functional requirements for cabinet door components. These requirements balance flexibility in door opening, safety in use, and adaptability to space. Specifically, cabinet design demands that door components have an instantaneous stopping function during opening / closing (i.e., maintaining the current angle after external force is removed), while also supporting larger opening angles to meet equipment maintenance needs. Furthermore, it is necessary to address the issue of interference with the internal space of traditional door stoppers.

[0003] In related technologies, standard frame cabinets typically use universal door stop devices, whose core function is limited to limiting the maximum opening angle of the door panel relative to the welded frame through a physical limiting structure, thereby preventing damage to the hinge mechanism due to excessive opening; the design logic of such universal door stop devices focuses on mechanical limit protection, and achieves angle control through rigid contact.

[0004] However, the above-mentioned universal stop valve device has the following problems:

[0005] First, the lack of damping control function makes it impossible to achieve smooth movement control of the door panel during opening / closing. It cannot stop instantaneously at any position, nor can it maintain the angular stability of a stationary state.

[0006] Second, the outline design of traditional door stoppers does not take into account the optimization of the internal space of the cabinet. When the door is closed, its protruding structure will occupy the effective space of the cabinet bottom frame cavity, which is easy to interfere with other installation accessories in the cabinet (such as cable management components, guide rail system, etc.).

[0007] Third, the rigid limiting structure restricts the maximum opening angle of the door panel, which cannot meet the functional requirements for opening angle in special scenarios. Utility Model Content

[0008] In response to the shortcomings of the existing production technology, the applicant provides a sliding damping stop device for frame cabinets, thereby achieving motion damping and instantaneous stopping of the sliding damping stop device attached to the cabinet door panel assembly, and the cabinet door panel assembly can open to the largest possible angle compared to a standard cabinet.

[0009] The technical solution adopted in this utility model is as follows:

[0010] A sliding damping stop door device for frame cabinets, comprising a sliding damping stop door device;

[0011] The sliding damping stopper includes a base assembly, a connecting rod assembly, and a transition plate.

[0012] The base assembly is assembled with the connecting rod assembly around the screw shaft. The connecting rod assembly, disc spring and flange nut are connected in series from bottom to top. Shims are provided on both the upper and lower sides of the connecting rod assembly. The disc spring is compressed by adjusting the flange nut to generate rotational damping.

[0013] The connecting rod assembly is assembled with the transition plate centered on the threaded pin. From bottom to top, the flange gasket, transition plate, gasket, and flange nut are coaxially connected in series. The cylindrical surface of the flange gasket is embedded in the sliding groove of the transition plate. Adjusting the flange nut causes the gasket clamped above the transition plate and the flange gasket below to undergo elastic compression deformation, thereby obtaining the combined frictional resistance at the rotary hinge and sliding contact surface.

[0014] As a further improvement to the above technical solution:

[0015] In one embodiment, the base assembly includes a base plate and a screw shaft; the base plate has a first chamfered hole, the screw shaft has a chamfered flange, the chamfered flange is pressed into the first chamfered hole with an interference fit, and the thickness T1 of the chamfered flange is greater than the thickness T2 of the base plate, so that the friction surface of the screw shaft is higher than the exposed surface of the base plate.

[0016] In one embodiment, the connecting rod assembly includes an arc-shaped connecting rod, a chamfered washer, and a threaded pin; the inner arc side of the connecting rod is provided with a clearance notch, and both ends are respectively provided with countersunk holes and a second chamfered hole; the chamfered washer is pressed into the second chamfered hole with an interference fit, and its thickness T4 is greater than the connecting rod thickness T3; the pin of the threaded pin is pressed into the countersunk hole with an interference fit, and the countersunk head is flush with the surface of the countersunk hole.

[0017] In one embodiment, the transition bend includes: a mounting surface and a plurality of second mounting holes thereon; a first folded edge and a second folded edge perpendicular to the mounting surface; an oblique bridging edge and a third folded edge perpendicular to it; and a fourth folded edge parallel to the first folded edge, the surface of which is provided with a groove.

[0018] In one embodiment, the gasket and flange gasket are made of engineering plastic to provide lubrication at the metal contact surface and protect the surface treatment layer.

[0019] In one embodiment, when the disc spring is compressed, a preset elastoplastic deformation occurs at the rotational hinge surface between the base assembly and the connecting rod assembly, forming frictional resistance.

[0020] In one embodiment, the flange face of the flange gasket contacts the bottom surface of the fourth fold, and the cylindrical surface slides with the groove. The combined frictional resistance of the rotational hinge and the cylindrical surface sliding is achieved by the compression of the gasket.

[0021] In one embodiment, the clearance notch abuts against the door flange when the cabinet door is opened.

[0022] In one embodiment, the base assembly is fixed to the second modular hole of the cabinet bottom frame through the first mounting hole, and the adapter plate is fixed to the first modular hole of the door panel assembly through the second mounting hole.

[0023] In one embodiment, when the cabinet door is closed, the outer arc profile of the connecting rod is flush with the upper part of the inner cavity of the cabinet bottom frame to reduce space occupation.

[0024] The beneficial effects of this utility model are as follows:

[0025] This utility model has a compact structure. Between the base assembly and the connecting rod assembly, a disc spring compresses a gasket to generate elastic deformation, forming an adjustable rotational friction resistance, which enables the door panel to be instantly suspended at any angle. The flange gasket between the connecting rod assembly and the transition plate is embedded in a groove, which, together with the gasket compression, provides both rotational hinge resistance and sliding resistance, ensuring smooth door panel movement.

[0026] This utility model also has the following advantages:

[0027] (1) The inner arc clearance notch of the connecting rod of this utility model avoids the door fold when it is opened, so that the door panel opens at a large angle to meet the equipment maintenance needs; when closed, the outer arc contour of the connecting rod is flush with the inner cavity of the cabinet bottom frame, reducing space occupation and solving the problem of interference with cables and guide rails.

[0028] (2) The thickness T1 of the beveled flange of the base assembly of this utility model is greater than the thickness T2 of the base plate, forming a protruding friction surface; the thickness T4 of the beveled pad in the connecting rod assembly is greater than the thickness T3 of the connecting rod, forming a pad limiting boss; both are assembled into an assembly reference surface by interference fit, simplifying the damping adjustment process; the flange nuts at both locations can adjust the compression of the disc spring and the pad, achieving precise control of the damping force.

[0053] like Figures 1-4 The accompanying drawing shows a schematic diagram of the structural state of a sliding damping stop door device for a frame cabinet according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0054] This application provides a sliding damping door stop device for frame cabinets, including a sliding damping door stop 10, which is composed of a base assembly 20, a connecting rod assembly 30, and a transition plate 40.

[0055] Please see Figures 2-3 In some embodiments, the base assembly 20 is assembled from a base plate 21 and a screw shaft 22 by a press-fitting process; wherein, the base plate 21 has a first chamfered hole 213, and the chamfered flange 221 of the screw shaft 22 is pressed into the hole with an interference fit. The thickness T1 of the chamfered flange 221 is greater than the thickness T2 of the base plate 21, so that the friction surface 222 of the screw shaft 22 is higher than the exposed surface 211 of the base plate 21.

[0056] Please see Figure 4In some embodiments, the connecting rod assembly 30 includes an arc-shaped connecting rod 31, a chamfered washer 32, and a threaded pin 33; wherein, the inner arc side of the connecting rod 31 is provided with a clearance notch 312, and countersunk holes 311 and second chamfered holes 313 are opened at both ends; the chamfered washer 32 is pressed into the second chamfered hole 313 with an interference fit, and its thickness T4 is greater than the thickness T3 of the connecting rod 31; the pin 332 of the threaded pin 33 is pressed into the countersunk hole 311, and the countersunk head 333 is flush with the surface of the countersunk hole 311.

[0057] Please continue reading. Figure 2 In some embodiments, the transition bend 40 has a Z-shaped structure, including a mounting surface 41 and a second mounting hole 42 thereon, a vertical first folded edge 43 and a second folded edge 44, an oblique bridging edge 45, a vertical third folded edge 46, and a fourth folded edge 47 parallel to the first folded edge 43. An elongated groove 48 is formed on the surface of the fourth folded edge 47.

[0058] In some embodiments, the rotational damping assembly process of this application is as follows: with the screw shaft 22 of the base assembly 20 as the center, the washer 50, the connecting rod assembly 30, the washer 50, the disc spring 60 and the flange nut 70 are connected in series in a coaxial manner; the flange nut 70 is adjusted to compress the disc spring 60, so that the washer 50 undergoes elastic-plastic deformation, and an adjustable rotational frictional resistance is formed at the friction surface 222.

[0059] In some embodiments, the composite damping assembly process of this application is as follows: with the threaded pin 33 of the connecting rod assembly 30 as the center, a flange washer 80, a transition bend 40, a gasket 50, and a flange nut 70 are sequentially connected in a coaxial manner. The cylindrical surface 82 of the flange washer 80 is embedded in the sliding groove 48, and its flange surface 83 contacts the bottom surface of the fourth folded edge 47; the flange nut 70 is adjusted to compress the gasket 50, so that the cylindrical surface 82 and the sliding surface of the sliding groove 48 and the rotating surface of the threaded pin 33 generate frictional resistance synchronously.

[0060] Please see Figures 5-6 In some embodiments, the installation process of the adapter bend plate 40 is as follows: the mounting surface 41 of the adapter bend plate 40 abuts against the horizontal square tube 112 of the door panel assembly 110, the first folded edge 43 and the second folded edge 44 respectively position the horizontal square tube 112 and the vertical square tube 113, and the self-tapping screw 90 passes through the second mounting hole 42 and locks into the first modular hole 114.

[0061] In some embodiments, the installation process of the base assembly 20 is as follows: the bottom surface of the base assembly 20 abuts against the bottom frame 130 of the cabinet (near the door hinge 120), forcing the door fold 111 to engage with the clearance notch 312; the self-tapping screw 90 passes through the first mounting hole 212 and locks into the second modular hole 131.

[0062] In some embodiments, such as Figure 5 As shown, the outer arc contour of the connecting rod 31 in the closed cabinet door 100 is flush with the upper part of the inner cavity of the cabinet bottom frame 130, reducing space occupation;

[0063] In some embodiments, such as Figure 6 As shown, the clearance notch 312 in the open cabinet door 140 avoids interference with the door flange 111, allowing the door panel to open at a large angle.

[0064] In some embodiments, the gasket 50 and flange gasket 80 are made of engineering plastic to protect the metal surface treatment layer; by independently adjusting the two flange nuts 70, the frictional resistance of rotational damping and composite damping can be precisely controlled, so as to achieve instantaneous suspension and smooth movement of the door panel at any position.

[0065] In summary, the structure of this utility model is reasonable. Between the base assembly 20 and the connecting rod assembly 30, the disc spring 60 compresses the gasket 50 to generate elastic deformation, forming an adjustable rotational friction resistance, which enables the door panel to be instantly suspended at any angle. The cylindrical surface 82 of the flange gasket 80 between the connecting rod assembly 30 and the transition plate 40 is embedded in the sliding groove 48. With the compression of the gasket 50, it provides both rotational hinge resistance and axial sliding resistance, ensuring smooth door panel movement.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
