Description

Technical Field

[0001] The invention relates to the technical field of cable bridges, in particular to a quickly connected combined cable bridge. Background Art

[0002] Cable trays are carriers that can provide support and protection for cables. They are mostly composed of brackets, supports, installation accessories, etc. They can help cables resist harsh natural environments such as moisture, dust, corrosive gases, etc. during their use. Cable trays can also make cable laying more convenient and quick.

[0003] During the installation process of some existing cable trays, the cable trays are first installed according to the path where the cables are to be installed. However, since the installation path of the cables is long, multiple cable trays need to be assembled and connected together for use. At this time, it is necessary to accurately drill holes and install the cable tray in advance according to the installation position of the cable tray. That is, the staff needs to use a tape measure to drill holes at equal intervals according to the number of cables to be placed in the cable tray to ensure safe use. This method of measuring the spacing before drilling and installing will greatly reduce the installation efficiency and needs to be improved. Summary of the invention

[0009] The outer wall of the adjusting screw is provided with a nut adapted thereto, and the nut can be used to provide protection for the waist of the adjusting screw and to limit the movable space of the supporting frame when the supporting frame is clamped by the clamping plate and the supporting plate.

[0010] A groove is arranged on the outer wall of the lifting rod, and a plurality of teeth that can mesh with each other are arranged on the inner wall of the groove and the side wall of the bonding plate, so that the lifting rod can be fixed at a desired height for use after the bonding plate is bonded to the inner wall of the groove of the lifting rod.

[0011] The driving gear is movably fitted with the front end face of the cross slide, and a plurality of teeth that can mesh with each other are arranged on the outer wall of the driving gear and the side wall of the front end face of the cross slide, and a handle is installed on the top of the driving gear to facilitate the translational movement of the cross slide by rotating the driving gear.

[0012] A cross slide matched with the cross slide is arranged on the top of the protrusion, so that the cross slide can move translationally in the cross slide.

[0013] A spring is arranged in the opening at the bottom end of the L-shaped linkage plate, and the two ends of the spring are respectively fixedly connected to the inner wall of the opening on the L-shaped linkage plate and the telescopic plate, so as to prevent the telescopic plate from being fixedly installed on the linkage plate and causing the rotating cross bar to be unable to rotate downward.

[0014] Openings are provided at both upper and lower ends of the push plate, and the length and width of the openings are adapted to the length and width of the long head of the L-shaped adjustment plate, and spring plungers are provided on the front and rear inner walls of the L-shaped adjustment plate. Several arc-shaped grooves adapted to the spring plungers are vertically provided on the front and rear inner walls of the opening on the push plate, which facilitates the L-shaped adjustment plate to be fixed at different heights for use.

[0015] The additional plate is provided with a slide groove adapted to the translation plate, the translation plate is placed in the slide groove, and the locking screw penetrates the inner wall of the slide groove and extends to the periphery of the slide groove, so that the locking screw can push the translation plate to translate in the slide groove during rotation.

The positioning and mounting plate can be conveniently installed at a desired position for use through the wall-connecting screws.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses a cross slide to translate the L-shaped adjustment plate during the movement, which pushes the sleeve plate to rotate. The sleeve plate drives the connecting plate, the second rotating rod, and the supporting plate to rotate. The supporting plate contacts the bottom side wall of the positioning installation plate during the rotation, so that the T-shaped slider is fixed in the T-shaped slide groove on the positioning installation plate. This not only facilitates the adjustment of the spacing between the supporting plates of one of the adjacent cable tray components according to the number of cables driven to be contained in the later stage, but also allows the T-shaped slider to be fixed to different positions of the positioning installation plate for use at will, and the positioning installation plate can be efficiently installed and fixed before the cables are installed, avoiding the need for precise measurement, positioning and drilling for the installation of the positioning installation plate.

[0018] During the translational movement of the cross slide, the L-shaped toggle plate will contact the L-shaped linkage plate and rotate while following the movement of the cross slide. The L-shaped linkage plate drives the rotating cross bar and the bonding plate to rotate. After the bonding plate rotates and fits the lifting rod, the mutually meshing teeth on the bonding plate and the outer wall of the lifting rod limit the lifting rod from continuing to move up and down, so that the pallet can be set at a fixed height for use.

[0019] The translation of the cross slide will push the push plate and the L-shaped adjustment plate to move. The L-shaped adjustment plate will push the sleeve plate and the toggle plate to rotate during the movement. During the rotation of the toggle plate, the pressure plate will move downward and cooperate with the support plate to press and lock the support frame. At this time, the rotating plate will rotate synchronously and drive the linkage plate to rotate during the rotation. The second rotating shaft installed on the linkage plate will rotate the second gear plate and reverse the gear plate in the process of following the rotation of the linkage plate, so that the rotating shaft and the clamping plate will rotate synchronously, and the clamping plate will cooperate with the side wall of the L-shaped support plate to clamp and fix the support frame to avoid shaking of the support frame during use.
