Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a bending protection device for wiring cables. Background Art

[0002] With the popularization of automation equipment, the electromechanical installation industry came into being. Electromechanical installation includes the installation of equipment, lines, and pipelines for general industrial and public and civil construction projects, 35 kV and below substation projects, and the production and installation of non-standard steel components. In the process of electromechanical installation, cable laying is one of the indispensable tasks. In the process of cable laying, due to the wall structure of the building, the cables usually cannot be extended in a straight line.

[0003] For example, a cable bend protection device for electromechanical installation wiring with a publication (announcement) number of CN213717503U includes a mounting plate and a protection strip, wherein the mounting plate is L-shaped, an L-shaped protection strip is fixed on the mounting plate, a guide groove is provided in the protection strip, a clamping strip is slidably connected to the protection strip, and the clamping strip passes into the guide groove, a fastening plate is fixedly connected to the end of the clamping strip away from the guide groove, a plurality of fastening screw holes are provided on the fastening plate, a top tightening screw hole corresponding to the fastening screw hole is provided on the protection strip, and a clamping plate is fixed to the clamping strip in the guide groove. The utility model protects the cable bends in electromechanical installation wiring, can be quickly installed at the corner of a building wall and allow cables to pass through, and uses a fastening plate, a clamping plate and a pressing plate to clamp and fix the two extended parts of the cable bend, so that the cable bend is in a stress-free state, avoiding bending and breaking, and extending its service life.

[0004] However, based on the working principle proposed in the above patent, the applicant believes that when the above device pulls the cable during the wiring process, it is easy to cause friction between the cable and the clamping plate, which is easy to cause damage to the protective device and wear on the cable surface. If the operator pulls the fastening plate in real time, the complexity of the wiring process and the dependence of the operation will be increased. At the same time, since the angle of the protective shell is at a right angle, the radius of the wire harness or cable at the bend is too small, which may cause excessive pressure on the conductor or insulation layer inside the cable, thereby damaging the cable or even causing it to break.

[0005] Therefore, in order to solve the above problems, a wiring cable bending point protection device is proposed. Utility Model Content

[0012] Preferably, auxiliary threading holes are provided in the middle portions of the mounting plate and the back side of the special-shaped protective shell.

[0013] Preferably, slide grooves are provided on both the upper and lower sides of the special-shaped protective shell.

[0014] The beneficial effects of the utility model are:

[0025] The following is combined with Figure 1-5 To further explain this application in detail,

[0026] The embodiment of the present application discloses a wiring cable bending protection device, comprising a special-shaped protective shell 1; a special-shaped assembly plate 2 is movably installed on one side of the inner cavity of the special-shaped protective shell 1, a plurality of through grooves 3 are opened in the middle part of the special-shaped assembly plate 2, a positioning rod 4 is fixedly installed inside the through groove 3, a concave rotating wheel 5 is movably installed on the surface of the positioning rod 4, connecting plates 6 are fixedly installed on the upper and lower sides of the special-shaped assembly plate 2, a transmission rod 7 is fixedly installed on one side of the connecting plate 6, positioning plates 8 are fixedly installed on the upper and lower sides of the middle part of the special-shaped protective shell 1, a through hole 9 is opened on the front side of the positioning plate 8, a spring 10 is movably installed on the surface of the transmission rod 7 and located on the outside of the positioning plate 8, and a baffle 11 is threadedly connected to one end of the transmission rod 7.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 Through the structural design of the special-shaped assembly plate 2, the through groove 3, the positioning rod 4, and the concave rotating wheel 5, and through the mutual cooperation between the structures, the function of cable bending protection is realized, thereby limiting the outer angle of the cable bending, and reducing the mutual wear between the cable and the protection device during the cable pulling process, avoiding the disadvantage of requiring manual adjustment to provide cable activity space, and solving the problem of excessive reliance on manual intervention. Through the structural design of the connecting plate 6, the transmission rod 7, the positioning plate 8, the spring 10, and the baffle 11, and through the mutual cooperation between the structures, the function of pushing the concave rotating wheel 5 to hold the cable is realized, thereby the cable can be accurately positioned, and the stability of the cable after deployment can be stably maintained.

[0028] An L-shaped retaining seat 12 is fixedly installed on the other side of the inner cavity of the special-shaped protective shell 1, and the middle part of the L-shaped retaining seat 12 is provided with a rounded corner.

[0029] Reference Figure 1 , Figure 3 , Figure 4 The L-shaped stop 12 can be used to limit the inner angle of the cable after bending by using its rounded corners, thereby cooperating with the concave rotating wheel 5 to control the angle of the cable after bending, avoiding excessive bending of the cable to cause damage to the internal conductor or insulation layer, and solving the problem of excessive bending of the cable.

[0030] A plurality of first slots 13 are formed on the surface of the L-shaped stop 12 .

[0031] Reference Figure 1 , Figure 3 , Figure 4 The first card slot 13 facilitates the support of the outer side of the bent cable, thereby achieving the purpose of limiting the position of the cable.

[0032] A plurality of second slots 14 are formed on one side of the special-shaped assembly plate 2 .

[0033] Reference Figure 1 , Figure 3 , Figure 5 The second card slot 14 facilitates the support of the inner side of the bent cable, thereby cooperating with the first card slot 13 to achieve the purpose of cable clamping. At the same time, the first card slot 13 and the second card slot 14 can also block different cables from each other, reduce mutual interference between cables, and avoid chaotic distribution of cables.

[0034] A mounting plate 15 is fixedly mounted on the back of the special-shaped protective housing 1 , and a plurality of mounting holes 16 are provided on both upper and lower sides of the front of the mounting plate 15 .

[0035] Reference Figure 1 and Figure 2 The mounting plate 15 and the mounting holes 16 facilitate the fast deployment of the device to the corner of the wall by fixing bolts. At the same time, the mounting holes 16 and the fixing bolts cooperate to ensure the stability of the special-shaped protective housing 1 during operation.

[0036] Auxiliary threading holes 17 are provided in the middle of the mounting plate 15 and the back side of the special-shaped protective housing 1 .

[0037] Reference Figure 2 and Figure 4 The auxiliary threading hole 17 facilitates the intervention of the staff and helps the cable to bend quickly.

[0038] Slide grooves 18 are provided on both upper and lower sides of the special-shaped protective housing 1 .

[0039] Reference Figure 3 and Figure 4 The slide groove 18 is used to provide the connecting plate 6 with a movable space, thereby achieving the purpose of making the special-shaped assembly plate 2 movable. At the same time, the connecting plate 6 can be limited to prevent it from shaking left and right.

[0040] Working principle: When using this device, the staff pushes the baffle 11, and the spring 10 is compressed and deformed by the baffle 11. At the same time, the baffle 11 drives the connecting plate 6 to move through the transmission rod 7. During this period, the connecting plate 6 is limited by the slide groove 18, and the special-shaped assembly plate 2 is driven to move toward the installation plate 15 by the connecting plate 6. At this time, the gap between the first card slot 13 and the second card slot 14 increases, and the cable is inserted between the card slots. The staff releases the baffle 11, and the spring 10 simultaneously releases the tension to push the baffle 11 to move, and the special-shaped assembly plate 2 is reset by the baffle 11, and gradually enters the interior of the special-shaped protective shell 1 with the cable. After reaching the middle position, when one end of the cable contacts the concave rotating wheel 5, the concave rotating wheel 5 is pushed to rotate, and the concave rotating wheel 5 is limited by the positioning rod 4. When the concave rotating wheel 5 rotates, the cable is driven to bend. At the same time, the staff pushes one end of the cable through the auxiliary threading hole 17 to make the cable bend quickly. As the cable is gradually pushed, the concave rotating wheel 5 cooperates with the rounded corner of the L-shaped support seat 12 to limit the cable surface to prevent excessive bending. The bent cable is released from the special-shaped protective shell 1 along the gap between the first card slot 13 and the second card slot 14, and finally contacts the angle surface of the wall through the mounting plate 15, and the positioning bolt is installed through the mounting hole 16.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
