Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a scratch-resistant connection joint for stainless steel cable trays. Background Technology

[0002] Stainless steel cable trays are widely used in cable laying projects in power, communication and chemical environments due to their excellent corrosion resistance and aesthetics. In actual installation, the length of a single cable tray is limited, so connectors are needed to connect multiple sections of the cable tray to achieve long-distance laying.

[0003] Existing connection methods typically use connecting plates or bridge structures, fixing the ends of two cable tray sections together with bolts. Stainless steel cable trays have high requirements for surface finish. During installation, the ends of the two cable tray sections need to be precisely aligned. If there is a misalignment, friction and collision will occur at the ends of the cable trays or connecting parts during the tightening process, which will cause scratches on the stainless steel surface, damage the aesthetics, and affect the corrosion resistance.

[0004] Furthermore, the cable needs to pass through the channel formed inside the connector. Traditional connectors have the tail end of the connecting bolt, the cut edge of the metal plate, or the installation step inside. During the laying or replacement of the cable, the cable insulation layer comes into contact with these rough or sharp structures, which can cause scratches, damage the insulation layer, and leave safety hazards. In addition, the connector lacks an effective structure for sorting and fixing the cable. The cable is piled up messily at the connector, which not only affects subsequent maintenance but also hinders heat dissipation.

[0005] Therefore, this utility model proposes a scratch-resistant connection joint for stainless steel cable trays to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology of stainless steel cable tray connectors, such as the cable tray surface being scratched during butt joint installation and the internal structure of the connector scratching the cable, as well as the lack of effective cable management and fixation, this utility model aims to provide a scratch-resistant connector for stainless steel cable trays with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a scratch-resistant connection joint for stainless steel cable trays, including: cable tray one, cable tray two, and a docking mechanism and a cable management mechanism for connecting cable tray one and cable tray two. The docking mechanism includes a connecting bridge with protruding blocks fixed on both sides. The docking mechanism also includes a baffle, which is supported by a rotating shaft and has a wedge-shaped hole. A fixed shaft is fixed to the outer wall of the connecting bridge, and a wedge is rotatably installed on the fixed shaft. Furthermore, both cable tray 1 and cable tray 2 are provided with concave grooves for inserting convex blocks. A connecting arm is fixed to the outer wall of cable tray 1, and a rotating shaft is rotatably installed inside the connecting arm. The baffle is sleeved on the fixed shaft through a wedge hole and locked by a wedge block. The cable management mechanism includes a placement plate. Vertical grooves and horizontal grooves are provided on the inner wall of the connecting bridge, and the placement plate is slidably installed in the vertical grooves and horizontal grooves.

[0008] Preferably, the surface of the placement plate is provided with threaded grooves at equal intervals.

[0009] Preferably, the cable management mechanism further includes a retaining ring and a bolt, the bolt passing through the retaining ring and screwed into a threaded groove.

[0010] Preferably, a rubber pad is fixed to the inner wall of the retaining ring.

[0011] Preferably, connecting arms are fixed on both the front and rear sides of the outer wall of the cable tray.

[0012] Preferably, the wedge is rotatably mounted in the middle of the outer wall of the fixed shaft.

[0013] Preferably, the outer walls of the connecting bridge are fixed with fixed shafts on both the left and right sides.

[0014] Preferably, the vertical groove is opened on the left side of the inner wall of the connecting bridge, and the horizontal groove is opened at equal intervals on the inner wall of the connecting bridge.

[0015] This utility model has the following beneficial effects: 1. This utility model, by setting a cable management mechanism, includes a placement plate that can be slidably installed inside the cable tray, and a fixing ring fixed on the placement plate with a rubber pad on the inner wall, solves the problems of rough interior of cable tray joints, scratches when cables pass through directly, messy cable arrangement, and poor heat dissipation in the prior art. It can effectively protect cables, prevent scratches, and make the cables neatly arranged, thereby enhancing the heat dissipation effect.

[0016] 2. This utility model, by setting a docking mechanism, includes a connecting bridge with a convex block and a concave groove on the cable tray body. The connection is achieved by the insertion and engagement of the convex block and the concave groove. This solves the problems of difficult end alignment and scratching of the smooth surface of the cable tray due to friction during the docking and installation of stainless steel cable trays in the prior art.

Specifically, a fixing shaft 209 is fixed to the left and right sides of the outer wall of the connecting bridge 201. Each component is fixed with a fixed shaft 209, on which a wedge 208 is rotatably mounted. More specifically, the wedge 208 is rotatably mounted in the middle of the outer wall of the fixed shaft 209. The baffle 206 is sleeved on the fixed shaft 209 through the wedge-shaped hole 207 and locked by the rotation of the wedge 208. The cable management mechanism 3 includes a placement plate 305. The inner wall of the connecting bridge 201 is provided with a vertical groove 306 and a horizontal groove 307. Specifically, the vertical groove 306 is opened on the left side of the inner wall of the connecting bridge 201, and the horizontal groove 307 is equidistantly opened on the inner wall of the connecting bridge 201. The placement plate 305 is slidably mounted in the vertical groove 306 and the horizontal groove 307. The surface of the placement plate 305 is provided with threaded grooves 304 at equal intervals. The cable management mechanism 3 also includes a fixing ring 301 and a bolt 303. The bolt 303 passes through the fixing ring 301 and is screwed into the threaded groove 304. A rubber pad 302 is fixed on the inner wall of the fixing ring 301.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3The docking mechanism 2 includes a connecting bridge 201 as the main connecting body. Protruding blocks 202 are fixedly installed on both the left and right sides of the connecting bridge 201. Corresponding recessed grooves 203 are provided on the right side of cable tray 1 and the left side of cable tray 2. In the assembled state, the protruding blocks 202 of the connecting bridge 201 are inserted into the recessed grooves 203 of cable tray 1 and cable tray 2. This slot-fitting structure ensures initial positioning and anti-scratch guidance during docking. To lock the cable tray 1 and the connecting bridge 201, connecting arms 204 are fixed on the front and rear sides of the outer wall of cable tray 1. A rotating shaft 205 is rotatably installed inside the connecting arm 204. The docking mechanism 2 also includes a baffle 206, which is supported by a rotating shaft 205.

A wedge block 208 is rotatably installed in the middle of the outer wall of the fixed shaft 209. When the baffle 206 rotates to fit against the surface of the connecting bridge 201, the wedge-shaped hole 207 of the baffle 206 is sleeved on the fixed shaft 209. At this time, by turning the wedge block 208, the wedge block 208 presses the baffle 206, thereby firmly fixing the baffle 206 and the bridge frame 1, which is fixed with the baffle 206 by the connecting arm 204, to the connecting bridge 201.

[0022] As a preferred embodiment, to enhance the connection stability on the cable tray side 1, please refer to... Figure 1 and Figure 2 The cable tray 1 has connecting arms 204 fixed on both the front and rear sides of its outer wall.

[0023] As a preferred embodiment, for ease of operation of the wedge 208, please refer to... Figure 3 The wedge 208 is rotatably mounted on the middle part of the outer wall of the fixed shaft 209.

[0024] As a preferred embodiment, for providing the mounting position of the baffle 206, please refer to... Figure 3 The outer walls of the connecting bridge 201 are fixed with fixed shafts 209 on both the left and right sides.

[0025] As a preferred embodiment, to standardize the installation path of the placement plate 305 and achieve flexible layout, please refer to... Figure 4 The vertical groove 306 is opened on the left side of the inner wall of the connecting bridge 201, and the horizontal groove 307 is opened at equal intervals on the inner wall of the connecting bridge 201. The placement plate 305 can be inserted into the vertical groove 306 first, and then slid to the predetermined position of the horizontal groove 307.

[0026] As a preferred embodiment, for ease of installation of the cable management components, please refer to... Figure 4 The surface of the placement plate 305 is provided with threaded grooves 304 at equal intervals.

[0027] In a preferred embodiment, in order to fix the cable, the cable management mechanism 3, in addition to having a threaded groove 304, also includes a fixing ring 301 and a bolt 303. The bolt 303 passes through the fixing ring 301 and is threaded into the threaded groove 304, thereby fixing the fixing ring 301 onto the placement plate 305.

[0028] As a preferred embodiment, to prevent the retaining ring 301 from scratching the cable, please refer to... Figure 4 A rubber pad 302 is fixed to the inner wall of the retaining ring 301, and the rubber pad 302 elastically contacts the cable.

[0029] Working principle: When extending the length of cable tray 1, cable tray 1 and connecting bridge 201 are first aligned. Then, since convex blocks 202 are fixed on both the left and right sides of connecting bridge 201, the convex block 202 on the left is inserted into the concave groove 203 on the right side of cable tray 1, thus initially fixing cable tray 1 and connecting bridge 201. Then, the convex block 202 on the right is inserted into the concave groove 203 on the left side of cable tray 24, achieving initial connection between cable tray 1 and cable tray 24 through connecting bridge 201. The cooperation of multiple concave grooves 203 and convex blocks 202 reduces scratches between cable tray 1 and cable tray 24 during the docking process. Subsequently, since the outer wall of cable tray 1 is fixed with convex blocks 202 on both the front and rear sides, the connection is further strengthened. Connecting arm 204, the rotating shaft 205 inside connecting arm 204 provides support for baffle 206. At this time, the baffle 206 is pulled to move. Since the left and right sides of the outer wall of the connecting bridge 201 are fixed with fixed shafts 209, the baffle 206 can fit with the surface of the connecting bridge 201 through the hole of the wedge hole 207. Then, the wedge block 208 installed in the middle of the outer wall of the fixed shaft 209 is turned and rotated. The wedge block 208 presses the baffle 206, and the baffle 206 and the connecting bridge 201 are fixed. Thus, the cable tray 1 is locked to the connecting bridge 201 on one side by the docking mechanism 2 and connected to the cable tray 2 4. The docking mechanism 2 prevents the cable tray 1 and the cable tray 2 4 from scratching during docking. When replacing or installing cables, first insert the placement plate 305 into the vertical groove 306 on the left side of the inner wall of the connecting bridge 201. Then, push the placement plate 305 into the horizontal grooves 307 equidistantly opened on the inner wall of the connecting bridge 201. The cooperation between the placement plate 305 and the vertical groove 306 allows the placement plate 305 to slide and install itself on the inner wall of the connecting bridge 201. After sliding the placement plate 305 to the installation position through the horizontal groove 307, insert the placement plate 305 equidistantly through the vertical groove 306 according to the length of the connecting bridge 201. This supports and fixes the cables, reducing the scraping of the cables on the surface of the connecting bridge 201 and affecting their service life. Finally, screw in the bolts 303, the same number as the number of cables, into the equidistant grooves 306. The threaded groove 304 on the surface of the placement plate 305 allows the bolt 303 to be fixed to the surface of the placement plate 305 through the thread engagement of the bolt 303 and the threaded groove 304. Then, the cable is inserted into the inside of the fixing ring 301, which fixes the cable to reduce cable shaking. The equidistant installation enhances the heat dissipation of the cable. Because the inner wall of the fixing ring 301 is fixed with a rubber pad 302, the cable is less likely to be scratched by the fixing ring 301 during installation. The cable management mechanism 3 can plan the installation position of the cable to avoid installation chaos. The horizontal groove 307 and the threaded groove 304 allow the cable to be installed according to the actual situation, enhancing the flexibility of cable installation.
