Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wire troughs, specifically to a wire trough anti-loosening structure. Background Technology
[0002] Cable trays, also known as wiring ducts, are electrical tools used to neatly organize and secure power cords, data cables, and other wires to walls or ceilings. They provide a protective casing for the wires, preventing physical damage from being stepped on, squeezed, or caused by sharp objects.
[0003] Chinese patent application CN202421210927.3, entitled "A Multi-Layer Anti-Slip Structure for a Wire Groove," discloses a multi-layer anti-slip structure for a wire groove. The upper cover plate and the lower groove cavity are connected by an anti-slip structure to form a complete wire groove. The anti-slip structure includes a locking groove and a locking protrusion. The outer surface shape of the locking protrusion matches the inner surface shape of the locking groove. The outer surface of the locking protrusion and the inner surface of the locking groove are in full contact. Compared to point contact, this large-area surface contact increases the friction between the locking groove and the locking protrusion, improves the tightness of the connection between the upper cover plate and the lower groove cavity, and prevents the upper cover plate from slipping out of the lower groove cavity.
[0004] However, the above-mentioned patent still has the following shortcomings. Although the snap-fit groove and snap-fit protrusion do improve the assembly firmness between the slot cover and the slot body, if the internal wiring needs to be increased or decreased, the slot cover needs to be removed. Personnel need to manually squeeze the two sides of the slot body closer to each other, but the degree of deformation required for squeezing is large. This not only easily damages the slot body, but also requires force on both sides of the slot body. Therefore, it is extremely inconvenient to disassemble the slot cover. Therefore, a slot anti-loosening structure needs to be designed. Utility Model Content
[0005] In view of the above-mentioned technical problems, the purpose of this utility model is to overcome the inconvenience of disassembling the slot cover in the prior art.
[0006] To achieve the above objectives, this utility model provides a wire trough anti-loosening structure, which is applied to the trough body and the trough cover. The two outer walls of the wire trough body are recessed with strip-shaped grooves of the same length. The trough cover is equipped with at least one set of locking mechanisms. The trough cover is provided with a pair of first limiting protrusions of the same length that can contact the two inner walls of the wire trough body respectively.
[0007] The locking mechanism includes a pair of locking plates that are respectively mounted on the slot cover via hinge shafts arranged in the same length direction as the slot cover and can be locked into the corresponding strip slots, and a pair of elastic members respectively mounted on the corresponding hinge shafts for pushing the locking plates to lock into the strip slots.
[0008] Preferably, the two sides of the groove cover each have a second limiting protrusion of the same length direction that contacts the two outer walls opposite to the groove body.
[0009] Preferably, a plurality of first hinge parts are fixedly connected to the second limiting protrusion, which are equally spaced along the length direction, and the hinge shaft is assembled on any two adjacent first hinge parts;
[0010] The hinge shaft includes a first connecting rod and a second connecting rod that is threadedly connected to one end of the first connecting rod. The ends of the first connecting rod and the second connecting rod that are far apart from each other are both provided with a first limiting part.
[0011] Preferably, the card plate has a second hinge portion protruding from the middle for the hinge shaft to pass through, one end of the card plate has a wedge block protruding from it that matches the strip-shaped card groove, and the other end of the card plate has anti-slip texture.
[0012] Preferably, the card plate has a protruding second limiting part that can contact the second limiting protrusion.
[0013] Preferably, the elastic element is a metal spring sheet mounted on the hinge shaft, and the two ends of the metal spring sheet abut against the second limiting protrusion and the retaining plate, respectively.
[0014] Preferably, the side of the first limiting protrusion away from the groove cover is inclined away from the second limiting protrusion to form a flared portion.
[0015] According to the above technical solution, the beneficial effects of the anti-loosening structure of the wire trough provided by this utility model are as follows: the function of the first limiting protrusion is to prevent the two side walls of the wire trough body from getting close to each other and deforming, so that the clamping plate is firmly inserted into the strip groove. In addition, with the action of the elastic element, the trough cover is firmly assembled on the wire trough body. When disassembling the trough cover, it is only necessary to rotate the clamping plate to separate it from the strip groove, and the trough cover can be removed. The operation is simple and convenient.

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0026] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.
[0027] like Figure 1-5 As shown, a wire trough anti-loosening structure is applied to the trough body 1 and the trough cover 2. The two outer walls of the wire trough body 1 are recessed with strip-shaped grooves 3 of the same length direction. The trough cover 2 is equipped with at least one set of locking mechanism. The trough cover 2 is provided with a pair of first limiting protrusions 4 of the same length that can contact the two inner walls of the wire trough body 1 respectively.
[0028] The locking mechanism includes a pair of locking plates 5 respectively mounted on the slot cover 2 via hinge shafts 14 arranged in the same length direction as the slot cover 2 and capable of locking into the corresponding strip slots 3, and a pair of elastic members 6 respectively mounted on the corresponding hinge shafts 14 for pushing the locking plates 5 into the strip slots 3.
[0029] When in use, the slot cover 2 covers the slot body 1, and a pair of first limiting protrusions 4 contact the two inner walls of the slot body 1 respectively. The card plate 5 will be inserted into the strip-shaped card slot 3, thereby assembling the slot cover 2 onto the slot body 1.
[0030] The function of the first limiting protrusion 4 is to prevent the two side walls of the trough body 1 from getting close to each other and deforming, so that the clamping plate 5 is firmly inserted into the strip groove 3. With the help of the elastic element 6, the trough cover 2 is firmly assembled on the trough body 1. When disassembling the trough cover 2, it is only necessary to rotate the clamping plate 5 to separate it from the strip groove 3, and the trough cover 2 can be removed. The operation is simple and convenient.
[0031] On both sides of the groove cover 2, there are two second limiting protrusions 7 that are of the same length and respectively in contact with the two outer walls opposite to the groove body 1.
[0032] A pair of second limiting protrusions 7 can contact the two outer side walls of the wire trough body 1 to prevent the side walls of the wire trough body 1 from tilting and deforming outward due to the pressure of the internal wires. A pair of first limiting protrusions 4 and a pair of second limiting protrusions 7 can position the two side walls of the wire trough body 1 to prevent the wire trough body 1 from being deformed by force, and further improve the assembly firmness and stability of the trough cover 2.
[0033] The second limiting protrusion 7 is fixedly connected with a plurality of first hinge parts 8 that are equally spaced along the length direction, and the hinge shaft 14 is assembled on any two adjacent first hinge parts 8.
[0034] The hinge shaft 14 includes a first connecting rod 9 and a second connecting rod 10 that is threadedly connected to one end of the first connecting rod 9. The ends of the first connecting rod 9 and the second connecting rod 10 that are far apart from each other are both provided with a first limiting part.
[0035] Both the trough body 1 and the trough cover 2 are cut according to the usage situation. Because the second limiting protrusion 7 is provided with several equally spaced first hinge parts 8, even after cutting, the hinge shaft 14 can be assembled on any two adjacent first hinge parts 8, which is highly practical. The hinge shaft 14 is divided into a first connecting rod 9 and a second connecting rod 10 for easy installation.
[0036] The middle part of the card plate 5 is provided with a second hinge part through which the hinge shaft 14 passes. One end of the card plate 5 is provided with a wedge block 11 that matches the strip-shaped card groove 3. The other end of the card plate 5 is formed with anti-slip texture.
[0037] When the slot cover 2 is assembled on the slot body 1, the wedge block 11 will be inserted into the strip slot 3; when the slot cover 2 needs to be removed, the ends of a pair of locking plates 5 away from the wedge block 11 can be pinched at the same time to separate the pair of locking plates 5 from the corresponding strip slot 3.
[0038] The card plate 5 has a protruding second limiting part 12 that can contact the second limiting protrusion 7.
[0039] The second limiting part 12 can limit the maximum rotation angle of the card plate 5. Otherwise, the card plate 5 will rotate too much and cover the first limiting protrusion 4 and the second limiting protrusion 7, which is not conducive to the assembly of the groove cover 2 onto the groove body 1. The second limiting part 12 can improve the ease of use.
[0040] The elastic element 6 is a metal spring sheet mounted on the hinge shaft 14, and the two ends of the metal spring sheet abut against the second limiting protrusion 7 and the retaining plate 5, respectively.
[0041] The side of the first limiting protrusion 4 away from the groove cover 2 is inclined away from the second limiting protrusion 7 to form a flared portion 13.
[0042] The flared part 13 facilitates the first limiting protrusion 4 and the second limiting protrusion 7 to be engaged on both sides of the side wall of the groove body 1.
[0043] The preferred 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 specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0044] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0045] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
