Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to a cable tray cover plate locking structure. Background Technology

[0002] The main function of cable trays is to support cables, protect cables, and facilitate cable laying and maintenance. After the cables are laid in the cable tray, a cable tray cover plate is installed at its open end to facilitate the enclosure and protection of the cables.

[0003] When assembling cable tray covers with cable trays, they cannot be easily and tightly secured to the opening end of the cable tray according to its external dimensions. During assembly, the cable tray covers cannot adapt to elastic movement under stress, and the ends of the cable tray covers are prone to deformation under stress. Moreover, when the cable tray covers are long, the probability of deformation under stress is greater, affecting the service life of the cable tray. Therefore, we propose a cable tray cover locking structure to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a cable tray cover locking structure to solve the problems mentioned in the background art, such as the inability of current cable tray covers on the market to adapt to the external dimensions of the cable tray and securely fasten to the opening end of the cable tray, the inability of the cable tray cover to adapt elastically under force during assembly, the easy deformation of the end of the cable tray cover under force, and the greater probability of deformation when the cable tray cover is long, which affects the service life of the cable tray.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable tray cover locking structure, including a cable tray, a cover body is provided above the cable tray, a limit groove is provided at the lower end of the cover body, a rotating shaft is installed on the side of the cable tray, a support column is connected to the outside of the rotating shaft, a second spring is connected inside the support column, and a limit rod is connected to the upper end of the second spring.

[0006] A positioning block is connected to the inner wall of the cover plate body, and a positioning groove is provided on the side of the cable tray.

[0007] Preferably, the cover plate body includes a cover plate one, a cover plate two, a retaining plate and a retaining groove, wherein a retaining plate is installed at the end of the cover plate one near the cover plate two, and a retaining groove is provided at the end of the cover plate two near the cover plate one.

[0008] Preferably, a fixing plate and a limiting plate are respectively installed below the first cover plate and the second cover plate. A reinforcing rod is connected to the side of the fixing plate, the reinforcing rod passes through the limiting plate, and a spring is connected between the fixing plate and the limiting plate.

[0009] Preferably, the first cover plate and the second cover plate are engaged with each other by a locking plate and a locking groove, and the mating ends of the first cover plate and the second cover plate are provided with reinforcing rods at equal intervals.

[0010] Preferably, the lower side of the positioning block is inclined, and the positioning block and the positioning groove engage with each other.

[0011] Preferably, the support column forms a rotating structure with the cable bridge via a rotating shaft, and the upper end of the support column slides through a limiting rod, with the limiting rod engaging with the limiting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) When the cable tray cover locking structure is driven to be snapped onto the cable tray, cover plate one and cover plate two can be moved under force to adapt to the size of the cable tray and be snapped tightly onto the cable tray. At the same time, the positioning block is snapped into the positioning groove, which saves effort and quickly achieves the locking of the cover plate. Then, by driving the limit rod to retract into the support column and driving the support column to rotate, the limit rod is snapped into the limit groove, which can further lock the cover plate body. The cover plate locking structure is easy to operate and will not cause the end of the cover plate to deform due to force.

[0014] (2) The cable tray cover plate locking structure has reinforcing rods evenly distributed at the mating ends of cover plate one and cover plate two, which allows cover plate one and cover plate two to be stably separated and snapped together, and the reinforcing rods are used to reinforce and support the cover plate, thereby improving the compressive strength of the cover plate body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 The present invention provides the following technical solution: a cable tray cover locking structure, including a cable tray 1, a cover body 2 is provided above the cable tray 1, a limiting groove 12 is provided at the lower end of the cover body 2, a rotating shaft 9 is installed on the side of the cable tray 1, a support column 8 is connected to the outside of the rotating shaft 9, a second spring 10 is connected inside the support column 8, and a limiting rod 11 is connected to the upper end of the second spring 10.

[0024] Furthermore, the support column 8 forms a rotating structure with the cable tray 1 through the rotating shaft 9. The upper end of the support column 8 slides through the limiting rod 11. The limiting rod 11 and the limiting groove 12 are engaged with each other. The position and angle of the limiting rod 11 can be adjusted so that when the limiting rod 11 is engaged in the limiting groove 12, the cover plate is locked. When the limiting rod 11 moves out of the limiting groove 12, the locking of the cover plate can be released.

[0025] A positioning block 7 is connected to the inner wall of the cover plate body 2, and a positioning groove 13 is opened on the side of the cable tray 1.

[0026] Furthermore, the lower side of the positioning block 7 is inclined, and the positioning block 7 and the positioning groove 13 engage with each other, so that when the positioning block 7 contacts the cable tray 1, it can be driven by force to move the cover plate 201 and the cover plate 202, and the cover plate can be easily locked onto the cable tray.

[0027] Furthermore, the cover plate body 2 includes a cover plate 1 201, a cover plate 202, a retaining plate 203 and a retaining groove 204. The retaining plate 203 is installed at the end of the cover plate 1 201 near the cover plate 202, and the retaining groove 204 is opened at the end of the cover plate 202 near the cover plate 1 201.

[0028] Furthermore, a fixing plate 3 and a limiting plate 5 are respectively installed below the cover plate 1 201 and the cover plate 2 202. A reinforcing rod 4 is connected to the side of the fixing plate 3, and the reinforcing rod 4 passes through the limiting plate 5. A spring 6 is connected between the fixing plate 3 and the limiting plate 5.

[0029] Furthermore, cover plate 1 201 and cover plate 202 are engaged with each other by clamping plate 203 and clamping groove 204. Reinforcing rods 4 are evenly distributed at the mating ends of cover plate 1 201 and cover plate 202, so that the cover plate can be easily clamped onto the cable tray, and the reinforcing rods 4 are used to reinforce and support the cover plate.

[0030] Specifically, the cover plate body 2 is aligned with the cable tray 1, and the cover plate body 2 is pressed down so that the cover plate body 2 gradually covers the opening end of the cable tray 1. When the positioning block 7 contacts the cable tray 1, the positioning block 7 is moved by the obstruction of the cable tray 1, thereby driving the cover plate 1 201 and the cover plate 202 to move away from each other. At this time, the fixing plate 3 drives the reinforcing rod 4 to slide on the limiting plate 5, and at the same time stretches and stores the spring 6, so that the cover plate body 2 can be finely adjusted to adapt to the size of the cable tray 1 until the position of the positioning block 7 corresponds to the position of the positioning groove 13. Then the spring 6 can drive the fixing plate 3 and the limiting plate 5 to move relative to each other, thereby controlling the relative movement of the cover plate 1 201 and the cover plate 202. At this time, the locking plate 203 is locked into the locking groove 204, and the positioning block 7 is locked into the positioning groove 13, so as to achieve a tight locking between the cover plate body 2 and the cable tray 1.

[0031] Pressing the limiting rod 11 towards the support column 8 causes the limiting rod 11 to press and store force on the second spring 10, retracting the limiting rod 11 into the support column 8. Simultaneously, the support column 8 is driven to rotate. One end of the support column 8 rotates on the cable tray 1 via the rotating shaft 9, causing the limiting rod 11 to rotate upwards. Releasing the pressure on the limiting rod 11 allows the second spring 10 to control the limiting rod 11 to reset and move, locking the limiting rod 11 into the limiting groove 12, further locking the cover plate body 2. The reinforcing rod 4 can reinforce and support the cover plate body 2, improving its compressive strength. Content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
