[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, brackets (trays) and installation accessories. In trough type cable trays, the cover is mainly to better protect the cable tray, to prevent the cable tray from being damaged, and to increase the service life of the cable tray. Generally speaking, if it is installed in the ceiling, the ladder type cable tray does not need a cover, and the trough type and tray cable trays need to be covered, which can better prevent interference and dust.

[0003] For example, the patent with application number 202021315276.6 discloses a circuit bridge that is easy to install. The dust cover is fixedly connected to the main bracket by the combination of a dust cover, a threaded tube, a first bracket, a second bracket and screws. The installation of the second bracket and the first bracket facilitates the staff to quickly install the dust cover to speed up the installation and seal the device to ensure that the inside of the device remains clean, thereby preventing dust from entering the device. Although the circuit bridge has improved the installation method of the dust plate, from the overall installation process, the use of threaded tubes and screws to achieve fixed connection is still relatively cumbersome.

[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0027] like Figure 1-8 As shown, the circuit bridge comprises a tray 1 with an upper opening, a bracket 2 connected to the tray 1 for supporting the tray 1, and a cover plate 3 buckled on the upper opening of the tray 1, and also comprises a locking mechanism 4;

[0028] The locking mechanism 4 includes a vertical plate 41, a pressure plate 42 connected to the top of the vertical plate 41 for pressing the cover plate 3, a locking tongue 43 arranged on the vertical plate 41 and facing the same side as the pressure plate 42, and a locking hole 44 opened on the side wall of the tray 1; the locking tongue 43 has a first position in which the width is smaller than the locking hole 44 after compression and a second position in which the width is larger than the locking hole 44 after recovery.

[0029] The circuit bridge has lock holes 44 on both sides of the tray 1 and lock tongues 43 for locking the cover plate 3 at the open end of the tray 1. After the lock tongue 43 is compressed to make its width smaller than the lock hole 44, the lock tongue 43 is inserted into the lock hole 44. At this time, the lock tongue 43 is released and locked into the lock hole 44 after the width is restored under the action of the restoring force. At this time, the upper pressing plate 42 is pressed on the cover plate 3 to achieve the connection between the cover plate 3 and the tray 1. When removing, the lock tongue 43 is compressed again to make its width smaller than the lock hole 44, and then the cover plate 3 can be removed. The utility model realizes the connection between the cover plate 3 and the tray 1 through the locking mechanism, and the connection and installation are convenient and quick. At the same time, the lock tongue 43 is adopted, and the structure is simple and the reliability is high.

[0030] The locking tongue 43 includes an annular locking piece with one end connected to the vertical plate 41 , and a pressing portion is disposed at the other end of the annular locking piece.

[0031] By pressing the pressing portion, the lock-changing lock plate is deformed so that its width in the vertical direction is smaller than the height of the lock hole 44, that is, the first position. At this time, the annular lock plate, that is, the lock tongue 43 is inserted into the lock hole 44 and released. At this time, the annular lock plate returns to its shape under the action of the restoring force, that is, the second position, and is locked in the lock hole 44.

[0032] The distance between the lock hole 44 and the cover plate 3 is greater than or equal to the distance between the lock tongue 43 and the pressure plate 42. The vertical plate 41 is provided with an avoidance notch 45. The pressing portion includes a neck section 431 and a pressing section 432. The neck section 431 is located in the avoidance notch 45. The avoidance notch 45 can prevent excessive pressing and excessive recovery to keep it in the best state. In this embodiment, the avoidance notch 45 is a square hole. Of course, in some other embodiments, the avoidance notch 45 can also be a structure with one side open.

[0033] The bracket 2 shown includes a base 22 for supporting the tray 1, a connecting rod 23 arranged on the base 22, and a tie rod 24 with one end connected to the object to be fixed and the other end connected to the connecting rod 23. In this embodiment, one end of the tie rod 24 is fixed to the roof and the other end is connected to the connecting rod 23 to achieve the fixing of the bridge frame.

[0034] The base 22 includes a support beam 21, and connecting seats are provided at both ends of the support beam 21. The connecting rod 23 and the connecting seat are provided with adjustment holes 25, and fixing bolts are passed through the adjustment holes 25. By providing the adjustment holes 25, the height of the support beam 21 can be adjusted based on specific height requirements.

[0035] The bottom of the connecting seat is provided with a connecting hole, and the supporting beam 21 is provided with a waist hole 26 for connecting with the connecting hole. By providing the waist hole 26, the matching position of the connecting seat and the supporting beam 21 can be adjusted to avoid the situation that the error causes the failure of normal installation, and effectively improve the fault tolerance.

[0036] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
