Description

Technical Field

[0001] The utility model relates to the technical field of wire troughs, in particular to a multi-layer anti-slip structure of a wire trough. Background Art

[0002] Cable trough, also known as wiring trough, wiring trough, and cable trough, is an electrical tool used to organize power cables, data cables and other wires in a standardized manner and fix them to the wall or ceiling.

[0003] Existing cable ducts are mostly assembled by snapping together an upper cover and a lower trough cavity. The lower trough cavity is a trough body that can accommodate cables. When in use, the lower trough cavity is fixed to the building, and multiple cables are installed in the lower trough cavity. The upper cover plate and the lower trough cavity are snapped together and installed through a snap-fit ​​structure to complete the installation and wiring of the cable duct.

[0004] In practical applications, such as Figure 1 As shown, the snap-fit ​​structure is a matching structure of a snap-fit ​​groove and a snap-fit ​​hook. The snap-fit ​​groove and the snap-fit ​​hook are usually in multi-point limited contact. This snap-fit ​​structure is prone to the upper cover plate slipping off, causing unnecessary trouble and hidden dangers for the laying of the cable duct. Utility Model Content

[0005] In response to the problems in the related art, the present application discloses a multi-layer anti-skid structure for a wire trough, which solves the problem in the related art that the upper cover plate of the wire trough is easy to slide off.

[0006] To achieve the above objectives, this application provides the following technical solutions:

[0007] A multi-layer anti-skid structure for a wire trough includes an upper cover plate and a lower trough cavity, wherein the upper cover plate and the lower trough cavity are buckled and connected via an anti-skid structure, wherein the anti-skid structure includes a buckling groove and a buckling protrusion, wherein the outer side surface shape of the buckling protrusion is consistent with the inner side surface shape of the buckling groove, and the outer side surface of the buckling protrusion and the inner side surface of the buckling groove are in full contact connection.

[0008] As a further solution of the present application: the snap-fit ​​protrusion includes a snap-fit ​​plate one and a snap-fit ​​plate two, the snap-fit ​​plate one and the snap-fit ​​plate two are connected by a transition plate, the snap-fit ​​plate one is provided with a contact surface on the outer side, the snap-fit ​​plate two is provided with a contact surface two on the outer side, the transition plate is provided with a contact surface three on the outer side, the snap-fit ​​groove is provided with a contact surface four, a contact surface five and a contact surface six with matching shapes at corresponding positions of the contact surface one, the contact surface two and the contact surface three, the contact surface one is fully contacted with the contact surface four, the contact surface two is fully contacted with the contact surface five, and the contact surface three is fully contacted with the contact surface six.

[0009] As a further solution of the present application: the first buckled plate and the second buckled plate are connected in a V-shape via a transition plate.

[0010] As a further solution of the present application: the one contact surface is arranged in a horizontal surface shape, the second contact surface is arranged in an inclined surface shape, and the third contact surface is arranged in an arc surface shape.

[0011] As a further solution of the present application: the snap-fit ​​groove and the snap-fit ​​protrusion are connected by interference fit and full contact.

[0012] In summary, the beneficial effects of this application are:

[0013] 1. The wire trough has a multi-layer anti-skid structure. The upper cover plate and the lower groove cavity are buckled and connected through the anti-skid structure to form a complete wire trough. The anti-skid structure includes a buckling groove and a buckling protrusion. The shape of the outer side of the buckling protrusion is consistent with the shape of the inner side of the buckling groove. The outer side of the buckling protrusion and the inner side of the buckling groove are fully contacted. Compared with point contact, the large-area surface contact improves the friction between the buckling groove and the buckling protrusion, improves the close bonding force between the upper cover plate and the lower groove cavity, and avoids the upper cover plate from slipping from the lower groove cavity.

[0014] 2. The first buckle plate and the second buckle plate are connected in a V shape through a transition plate. The V-shaped structure of the first buckle plate and the second buckle plate allows the buckle protrusion to have a certain elastic variation range, so that the force between the buckle protrusion and the buckle groove is increased due to deformation, thereby improving the tight combination between the buckle protrusion and the buckle groove, and preventing the upper cover plate from slipping from the lower groove cavity.

[0015] 3. One contact surface is set as a horizontal surface, and the contact surface and the four contact surfaces have an upward interaction force. The second contact surface is set as an inclined surface, and the contact surface and the five contact surfaces have an interaction force in an inclined direction. The third contact surface is set as an arc surface, and the six contact surfaces are connected to the three contact surfaces in an enclosing surface contact manner. The contact area is larger and the friction between them is greater, which comprehensively ensures the stability of the combination of the upper cover plate and the lower groove cavity.

[0016] 4. The buckling groove and the buckling protrusion are connected by interference fit and full contact. The interference fit increases the interaction force between the buckling protrusion and the buckling groove, improves the bonding degree, and effectively prevents the upper cover plate from sliding relative to the lower groove cavity.

[0028] like Figure 2-3 As shown:

[0029] The multi-layer anti-skid structure of the wire trough includes an upper cover plate 1 and a lower trough cavity 2. The upper cover plate 1 and the lower trough cavity 2 are buckled and connected via the anti-skid structure. The upper cover plate 1 and the lower trough cavity 2 are buckled to form a complete wire trough.

[0030] The anti-slip structure includes a buckling groove 32 and a buckling protrusion 31 , the upper cover plate 1 is connected to the buckling protrusion 31 , and two sides of the lower groove cavity 2 are connected to the buckling groove 32 .

[0031] The shape of the outer side surface of the buckling protrusion 31 is consistent with the shape of the inner side surface of the buckling groove 32, and the outer side surface of the buckling protrusion 31 and the inner side surface of the buckling groove 32 are in full contact connection.

[0032] Compared with point contact, large-area surface contact improves the friction between the snap-fit ​​groove 32 and the snap-fit ​​protrusion 31, improves the tight bonding force between the upper cover plate 1 and the lower groove cavity 2, and prevents the upper cover plate 1 from sliding off the lower groove cavity 2.

[0033] Preferably, the buckling protrusion 31 includes a buckling plate 41 and a buckling plate 42, and the buckling plate 41 and the buckling plate 42 are connected by a transition plate 43, and the buckling plate 41 and the buckling plate 42 are connected in a V shape by the transition plate 43. The buckling groove 32 and the buckling protrusion 31 are connected in an interference fit and full contact. The interference fit and the V shape with elastic deformation increase the force between the buckling protrusion 31 and the buckling groove 32, and improve the tight combination.

[0034] Among them, a contact surface 51 is provided on the outer side of the first buckled plate 41, a contact surface 52 is provided on the outer side of the second buckled plate 42, and a contact surface 53 is provided on the outer side of the transition plate 43.

The shape of the outer side surface of the buckling protrusion 31 is consistent with the shape of the inner side surface of the buckling groove 32.
