Description

Technical Field

[0001] The utility model mainly relates to the technical field of silver-plated conductive rollers, in particular to an anti-shedding silver-plated conductive roller. Background Art

[0002] A conductive roller is a bearing-supported metal roller typically made of a highly conductive metal or alloy, such as copper, aluminum, or steel. Its function is to transmit power and signals, often serving as a connector between different circuits to ensure smooth current flow. Conductive rollers are widely used in industries such as metallurgy, machinery manufacturing, and electric power because they can withstand high voltage and high frequency power transmission. The silver-plated conductive roller, which extends a branch, enhances conductivity.

[0003] However, most conductive rollers on the market are integrated. For ease of use, some are designed as split structures. For example, Chinese patent application number CN201920268789.7 discloses a conductive roller that is connected solely by bolts. However, this design can loosen or fall off over extended periods of operation, posing a safety hazard. Therefore, it is necessary to propose a silver-plated conductive roller device that prevents fall-off to address the aforementioned technical issues.

[0004] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0005] The utility model provides an anti-shedding silver-plated conductive roller, which is used to solve the technical problems existing in the above background technology.

[0006] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a silver-plated conductive roller that prevents falling off, comprising a silver-plated conductive layer, a cavity layer being provided in the silver-plated conductive layer, an inner wall of the cavity layer being inlaid with an insulating layer, cavity holes being symmetrically provided on the left and right sides of the cavity layer, and anti-falling components being correspondingly plugged into the interior of both sides of the cavity layer; the anti-falling component comprises a fixed shaft, a fixed component being slidably mounted on the fixed shaft, the fixed component being connected to the end of the silver-plated conductive layer, when the anti-falling component is tightly plugged into the cavity layer, the fixed shaft and the fixed component are circumferentially fixed, a plurality of fixed blocks are correspondingly provided around one side of the fixed shaft, the plurality of fixed blocks can be driven to move radially in synchronization, an insulating gasket is provided on the outside of the fixed block, and fixation is achieved by unfolding and fitting the plurality of fixed blocks to the inner wall of the cavity layer.

[0007] Furthermore, a support platform is provided at one end of the fixed shaft, and a plurality of support rods are hingedly installed around the inner end of the support platform. A torsion spring is installed at the hinge between the support rod and the fixed shaft, and the other end of the support rod is rotatably connected to the fixed block and can be relatively folded.

[0008] Furthermore, a slot is provided on the inner side of the fixed block, a rotating shaft is provided in the middle of the slot, and the outer end of the support rod is rotatably installed on the rotating shaft; elastic ropes are installed at both ends of the rotating shaft, and the elastic ropes are connected to the fixed block.

[0009] Furthermore, the fixing assembly includes an annular fixing plate, and the fixing shaft is slidably fitted on the inner wall of the fixing plate; a plurality of threaded holes are evenly opened around the fixing plate, and the threaded holes correspond to the fixing holes and are connected by bolts; a limiting sleeve is correspondingly provided on the inner end face of the fixing plate, and a limiting hole is correspondingly provided in the middle part of the limiting sleeve for slidingly fitting with the support platform; sliders are evenly distributed around the fixing shaft in the limiting sleeve, and inlay grooves are evenly opened around the inner hole wall of the fixing plate, and the inlay grooves are slidably fitted with the protruding sliders.

[0010] Furthermore, the outer surface of the gasket has a curvature corresponding to that of the inner surface of the insulating layer.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0012] 1. The utility model has a reasonable design. By retracting the fixed shaft, the torsion spring and the support rod on the support platform are squeezed and contracted by the limiting hole. After being inserted from the cavity hole, the fixed shaft is loosened, and the support rod is automatically expanded under the action of the torsion spring, so that the gasket fits the insulating layer. When the fixed shaft is pressed, the support rod squeezes the fixed block and the gasket, forcing the gasket to squeeze the insulating layer, thereby avoiding falling off and dislocation caused by loosening of the bolts after the overall installation. Since the force points are dispersed and belong to the concentric axis, the overall fatigue of the equipment is dispersed, so that the device has a better service life.

[0013] 2. The utility model has a reasonable design. When the anti-falling component is unfolded and pressed against the silver-plated conductive layer, the sliders around the fixed shaft are plugged into the inlaid grooves around the inner wall of the fixed disk, so that the fixed shaft and the fixed component are circumferentially locked. The rotation of the fixed shaft drives the fixed disk to rotate, thereby driving the silver-plated conductive layer to rotate and transmit power. Since the original design is divided into three sections, the overall life of the equipment is increased, and the replacement material is reduced when replacing the silver-plated conductive roller, thereby reducing resource loss, thereby achieving energy saving and environmental protection.

[0014] It should be noted that the structures not introduced in the present invention do not involve the design points and improvement directions of the present invention, and are the same as the existing technology or can be implemented by using the existing technology, so they are not described in detail here.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0024] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," "provided with," "provided on," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components.

[0025] Example: Refer to the attached Figures 1 to 5 The present embodiment provides an anti-dropout silver-plated conductive roller, comprising a silver-plated conductive layer 1, a cavity layer 5 disposed within the silver-plated conductive layer 1, an insulating layer 4 embedded within the inner wall of the cavity layer 5, cavity holes 2 symmetrically disposed on the left and right sides of the cavity layer 5, and anti-dropout components 6 correspondingly inserted into the interior of the two sides of the cavity layer 5. The anti-dropout component 6 comprises a fixed shaft 601, on which a fixed component 7 is slidably mounted, the fixed component 7 being connected to the end of the silver-plated conductive layer 1. When the anti-dropout component 6 is tightly inserted into the cavity layer 5, the fixed shaft 601 and the fixed component 7 are circumferentially fixed, i.e., rotation of the fixed shaft 601 drives the fixed component 7 to rotate synchronously, thereby driving the silver-plated conductive layer 1 to rotate synchronously. A plurality of fixed blocks 607 are provided around one side of the fixed shaft 601. The plurality of fixed blocks 607 can be driven to move radially and telescopically synchronously. An insulating gasket 608 is provided on the outside of the fixed block 607. The plurality of fixed blocks 607 are unfolded and fit tightly against the inner wall of the cavity layer 5 to achieve fixation.

[0026] Specifically, a support platform 602 is provided at one end of the fixed shaft 601. Multiple support rods 604 are hingedly mounted around the inner end of the support platform 602. Torsion springs 603 are mounted at the hinged joints between the support rods 604 and the fixed shaft 601. The other ends of the support rods 604 are rotatably connected to a fixed block 607 and can be folded relative to each other. Specifically, a slot is provided on the inner side of the fixed block 607, and a rotating shaft 605 is provided in the middle of the slot. The outer ends of the support rods 604 are rotatably mounted on the rotating shaft 605. Elastic cords 606 are mounted at both ends of the rotating shaft 605. These elastic cords 606 are connected to the fixed block 607. The provision of the elastic cords 606 allows the fixed block 607 to tilt inward when the anti-drop assembly 6 is inserted, facilitating insertion into the cavity layer 5 from the corresponding cavity holes 2 on both sides of the silver-plated conductive layer 1.

[0027] The fixing assembly 7 includes an annular fixing plate 701, and the fixing shaft 601 is slidably mounted on the inner wall of the fixing plate 701; a plurality of threaded holes 704 are evenly arranged around the fixing plate 701, and the threaded holes 704 correspond to the fixing holes 3 and are connected by bolts; a limiting sleeve 703 is provided on the inner end surface of the fixing plate 701, and a limiting hole 7031 is provided in the middle of the limiting sleeve 703 to slide with the support platform 602; the fixing shaft in the limiting sleeve 703 is fixed. Sliders 609 are evenly distributed around 601, and inlay grooves 702 are evenly opened around the inner hole wall of the fixed disk 701. The inlay grooves 702 slide in contact with the protruding slides 609. By plugging and fitting the slides 609 around the fixed shaft 601 with the inlay grooves 702 around the inner wall of the fixed disk 701, the fixed shaft 601 and the fixed component 7 are circumferentially locked. The rotation of the fixed shaft 601 drives the fixed disk 701 to rotate, thereby driving the silver-plated conductive layer 1 to rotate and transmit power.

[0028] The outer surface of the gasket 608 corresponds to the curvature of the inner surface of the insulating layer 4, thereby achieving complete fit, increasing the contact surface, and improving the connection effect.

[0029] Working principle: By retracting the fixed shaft 601, the torsion spring 603 and the support rod 604 on the support platform 602 are squeezed and contracted by the limiting hole 7031, and then inserted from the cavity hole 2, and then the fixed shaft 601 is loosened to make the support rod 604 open, so that the gasket 608 fits the insulating layer 4, and then the fixed shaft 601 is pressed to make the support rod 604 squeeze the fixed block 607 and the gasket 608, forcing the gasket 608 to squeeze the insulating layer 4, thereby avoiding the falling off and dislocation caused by the loosening of the bolts after the overall installation. The concentric shaft disperses the overall fatigue of the equipment and makes the device have a better service life. While pressing the fixed shaft 601, because the slider 609 can be embedded in the limiting sleeve 703, the limiting sleeve 703 forces the slider 609 to slide into the embedding groove 702 by pressing the fixed shaft 601 to achieve a locked state. Since it is divided into three sections in the original design, the overall life of this equipment is increased, and the material to be replaced when replacing the silver-plated power-off roller is reduced, thereby reducing the loss of resources, thereby achieving energy saving and environmental protection.

[0030] The above embodiments only express a certain implementation method of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent of the present invention shall be based on the attached claims.
