Description

Technical Field

[0001] This utility model relates to the field of cable tray equipment technology, and in particular to a cable tray connection device. Background Technology

[0002] Cable trays are widely used in various fields, mainly to protect wires and cables. When using them, they need to be assembled and installed in conjunction with other cable trays. When existing cable trays are connected by bolts, the cable tray connection points are easily scratched by the cables, and the exposed bolt parts are also easy to scratch the cables. Utility Model Content

[0003] The purpose of this utility model is to provide a cable tray connection device to solve the problem that cables are easily scratched during the assembly and connection of existing cable trays.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A cable tray connection device includes a connecting seat and a fixing seat. The connecting seat and the fixing seat have cable grooves. The connecting seat is provided with at least two plug-in seats that mate with the cable tray. The plug-in seats have fixing grooves that adapt to the fixing seat and the cable tray. The bottom of the fixing groove has a fixing through hole. The lower end of the fixing seat is provided with a threaded connecting post that adapts to the fixing through hole. The fixing seat is provided with protective sleeves at both ends of the cable groove.

[0006] Furthermore, the inner sidewall of the fixing seat is provided with a first arc-shaped protrusion, and the inner bottom wall of the fixing seat is provided with a second arc-shaped protrusion. Both the first arc-shaped protrusion and the second arc-shaped protrusion have gaps with both ends of the fixing seat.

[0007] Furthermore, the protective sleeve is a U-shaped protective sleeve adapted to the cross-section of the fixing seat. The protective sleeve includes a bottom wing, an inner wing, and an outer wing. The inner wing and the outer wing are respectively disposed on both sides of the bottom wing. The outer wing, the bottom wing, and the inner wing form a slot adapted to the fixing seat. The size of the inner wing is smaller than the size of the gap, and the size of the outer wing is larger than the size of the gap.

[0008] Furthermore, the distance from the highest point of the first arc-shaped protrusion to the inner wall of the fixing seat is greater than the thickness of the inner wing, and the distance from the highest point of the second arc-shaped protrusion to the inner bottom wall of the fixing seat is greater than the thickness of the inner wing.

[0009] Furthermore, the protective sleeve is made of rubber or plastic.

[0010] This utility model has the following advantages:

[0011] By setting a fixing base and placing the threaded connection post at the lower end of the fixing base, the threaded connection is placed outside the cable tray. The fixing base can increase the contact surface with the cable tray, making the fixation more secure. The protective sleeve set at the end can effectively prevent the end face edges from scratching the cable, ensuring the safety of the cable during wiring and use. Attached Figure Description

[0026] refer to Figure 1-5 As shown, one embodiment of this utility model is as follows:

[0027] A cable tray connection device includes a connecting seat 1 and a fixing seat 2. The connecting seat 1 and the fixing seat 2 have cable grooves 3. The connecting seat 1 has at least two plug-in seats 4 that mate with the cable tray. The plug-in seats 4 have fixing grooves 5 that are adapted to the fixing seat 2 and the cable tray. The bottom of the fixing groove 5 has a fixing through hole 6. The lower end of the fixing seat 2 is provided with a threaded connecting post 7 that is adapted to the fixing through hole 6. The fixing seat 2 is provided with protective sleeves 8 at both ends of the cable groove 3.

[0028] In practical implementation, the cable tray has fixing holes at its ends corresponding to the fixing through holes 6. During assembly, the end of the cable tray is placed in the fixing groove 5, so that the fixing holes correspond to the fixing through holes 6. Then, the fixing seat 2 is pressed against the cable tray, so that the threaded connecting post 7 passes through the fixing hole and the fixing through hole in sequence. Finally, it is locked with a nut, thereby realizing the combination of adjacent cable trays. By setting the fixing seat 2 and placing the threaded connecting post 7 at the lower end of the fixing seat 2, the threaded connection is placed outside the cable groove. The fixing seat 2 can increase the contact surface with the cable tray, making the fixation more secure. The protective sleeve 8 set at the end can effectively prevent the end face edges from scratching the cable, ensuring the safety of the cable during wiring and use.

[0029] Furthermore, the inner sidewall of the fixing base 2 is provided with a first arc-shaped protrusion 9, and the inner bottom wall of the fixing base 2 is provided with a second arc-shaped protrusion 10. The first arc-shaped protrusion 9 and the second arc-shaped protrusion 10 are both separated from the two ends of the fixing base 2 by a gap 11.

[0030] The protective sleeve 8 is a U-shaped protective sleeve that fits the cross section of the fixed seat 2. The protective sleeve 8 includes a bottom wing 12, an inner wing 13, and an outer wing 14. The inner wing 13 and the outer wing 14 are respectively disposed on both sides of the bottom wing 12. The outer wing 14, the bottom wing 12, and the inner wing 13 form a slot that fits the fixed seat 2. The size of the inner wing 13 is smaller than the size of the gap 11, and the size of the outer wing 14 is larger than the size of the gap 11.

[0031] The distance from the highest point of the first arc-shaped protrusion 9 to the inner wall of the fixing seat 2 is greater than the thickness of the inner wing 13, and the distance from the highest point of the second arc-shaped protrusion 10 to the inner bottom wall of the fixing seat 2 is greater than the thickness of the inner wing 13.

[0032] The protective sleeve 8 is made of rubber or plastic.

[0033] The gap 11 formed between the arc-shaped protrusion and the end of the fixing seat ensures a smooth contact surface with the protective sleeve 8. Since the radial dimension of the fixing seat 2 is not large, the arc-shaped protrusion can slightly raise the cable, reducing the contact between the cable and the end protective sleeve 8 during wiring and reducing the probability of local friction damage to the inner wing 13 of the protective sleeve 8. The outer wing 14 is larger to provide a larger contact surface, effectively preventing the protective sleeve 8 from falling off after threaded fixing.

[0034] like Figure 6 As shown, in another embodiment, the connector 1 has three plug-in sockets forming a T-shaped structure. Figure 7 As shown, in another embodiment, the connector 1 has four plug-in sockets forming a cross-shaped structure. Figure 6 As shown in Figure 7, in a T-shaped or cross-shaped structure, an arc-shaped surface is provided at the corner of the cable groove 3 of the connector 1.

[0035] 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.
