[0002] Outdoor cables are devices installed outdoors to transmit electrical energy. When wiring outdoors, the non-suspended parts are generally fixed by clamps and screws. However, due to the different cable specifications and thicknesses, when the cables are fixed by universal clamps, the cables are prone to movement due to size mismatch, or excessive squeezing and damage, which in turn creates safety hazards. If an external mounting block is directly installed on the cable, it is not convenient to wind and store it. If an additional mounting block is configured for the cable, the cable is separated from the mounting block and is easily lost during storage, causing inconvenience in use. Summary of the invention

[0027] like Figure 1-6 As shown:

[0028] An outdoor cable processing device includes an outer frame 200, an inner shell 210 is connected to the outer frame 200 by screws, and cooling devices 220 are arranged on the upper and lower sides of the inner shell 210. The cooling device 220 is a device that can be refrigerated by powering on. It is a mature technology and will not be described here. An inlet 211 is opened on the upper side of the inner shell 210, and the left and right sides of the inner shell 210 are both connected to the pull rod 230 by a linear cylinder sliding. The outer ends of the two pull rods 230 are connected to one end of a half hoop 240 by a rotary cylinder rotation, and the two half hoop 240 can be rotated 90 degrees on the pull rod 230;

[0029] When it is necessary to coat the outside of the semi-finished cable with molten rubber, the semi-finished cable can be inserted into the inner shell 210, and a feeding device can be connected to the feed inlet 211. The feeding device is a device that can control the molten rubber to be introduced into the inner shell 210. It will not be described here. Then, the two rotary cylinders can be started to control the two half-hoops 240 to rotate 90° clockwise, so that the two half-hoops 240 can be assembled with the pull rod 230 and sleeved on the outside of the semi-finished cable. Then, the two linear cylinders can be started to drive the two pull rods 230 to slide toward the inside of the inner shell 210, so that the semi-finished cable can be fed into the inner shell 210 through the half-hoops 240. The finished cable is pushed into the inner shell 210, and then the feeding device can be opened to allow the molten rubber to enter the inner shell 210 through the feeding port 211 and fill the gap formed between the semi-finished cable and the inner shell 210. Then the cooling device 220 can be started, so that the molten rubber can be cooled by the cooling device 220 to complete the coating of this part of the molten rubber; then the two rotary cylinders can be started to allow the two half-hoops 240 to rotate 90° counterclockwise to reset, and then the linear cylinders can be reversely started so that the pull rod 230 can drive the half-hoops 240 to reset, so that the molten rubber coating of the outer side of the semi-finished cable can be completed in sequence;

[0030] By using a linear cylinder as a power source to push the pull rod 230 to move, the thrust of the pull rod 230 on the semi-finished cable can be quickly changed by adjusting the compressed air pressure. When the cooled molten rubber adheres to the inside of the inner shell 210, the semi-finished cable can be pushed out by increasing the air pressure to avoid affecting subsequent processing.

[0031] like Figure 4 As shown:

[0032] The inner shell 210 is provided with a guide frame 212 at both ends, and the pull rod 230 is slidably connected to the inside of the guide frame 212 through a linear cylinder; thus, the pull rod 230 can be limited by the guide frame 212 to prevent the pull rod 230 from being subjected to excessive resistance from the movement of the semi-finished cable during movement, resulting in deformation of the movement.

[0033] Further:

[0034] The feed port 211 is also slidably connected to a positioning bar 213, which is arranged on the rear side of the guide frame 212 and can be fixed to the guide frame 212 using screws; thereby, the pull rod 230 can be limited by adjusting the positioning bar 213, so that the pull rod 230 can only move within the distance between the front end of the positioning bar 213 and the front end of the guide frame 212, thereby adjusting the distance that the pull rod 230 can drive the semi-hoop 240 to move during the reciprocating motion, thereby ensuring that the molten rubber can accurately fall on the predetermined position of the semi-finished cable without being affected by changes in cable specifications.

[0035] like Figure 1 , 6 、11 as shown:

[0036] The inner side surfaces of the two half hoop rings 240 can be assembled into a cylindrical surface coaxial with the inner cylindrical surface of the inner shell 210. The inner diameter of the half hoop ring 240 is smaller than the inner diameter of the inner shell 210, so that when the half hoop ring 240 pushes the semi-finished cable to move, the half hoop ring 240 can slide in the part of the semi-finished cable that is not filled with molten rubber, and ensure that when the half hoop ring 240 pushes the semi-finished cable, it can accurately push a certain section of the semi-finished cable to stay in a predetermined position without being affected by the position where the half hoop ring 240 starts to push, thereby improving the processing range of the semi-finished cable that can be processed by the processing equipment without adjustment.

[0037] like Figure 5 As shown:

[0038] The front sides of the two pull rods 230 are both provided with stoppers 231, and the two half hoop rings 240 are both rotatably connected between the corresponding stoppers 231 and the pull rods 230. The stoppers 231 and the half hoop rings 240 are both provided with rounded corners. The movable ends of the half hoop rings 240 are provided with fixing devices that can be fixed at the corresponding positions of the pull rods 230. The fixing devices are magnetic sheets or plug rods that are consistent with the movement paths of the half hoop rings 240, so that the half hoop rings 240 can be connected to the pull rods 230 as a whole after rotating 90° clockwise. At the same time, the setting of the rounded corners can avoid interference between the rotating ends and the corresponding pull rods 230 during the rotation of the half hoop rings 240.

[0039] At the same time, the setting of the stop head 231 can make the half hoop 240 be clamped between the stop head 231 and the pull rod 230, thereby preventing the semi-finished cable from sticking to the inner wall of the inner shell 210 after the molten rubber is completely coated, resulting in difficulty in pushing the semi-finished cable by the half hoop 240, and causing the half hoop 240 to fall off the pull rod 230.

[0040] A method for processing an outdoor cable comprises the following steps:

[0041] S1: bonding an outer protective layer to the outside of the cable core to obtain a semi-finished cable;

[0042] S2: inserting the semi-finished cable into the inner shell 210;

[0043] S3: injecting molten rubber into the inlet 211 through the feeding device;

[0044] S4: Start the cooling device 220 to cool the molten rubber;

[0045] S5: Start the pull rod 230 to push the semi-finished cable forward through the pull rod 230;

[0046] S6: Repeat steps S3-S5 until all outdoor cables are processed.

[0047] like Figure 7-10 As shown:

[0048] An outdoor cable includes a cable core 000, the outer side of the cable core 000 is coated with an insulating layer 010, a plurality of fixing rings 100 are bonded to the outer side of the insulating layer 010, the plurality of fixing rings 100 are evenly arranged on the outer side of the insulating layer 010, a rubber protective layer 020 is filled between the fixing rings 100, the rubber protective layer 020 is arranged on the outer side of the insulating layer 010, a limiting strip 011 is arranged on the outer side of the insulating layer 010, the fixing ring 100 includes an inner fixing strip 110 and an outer fixing strip 120, the outer fixing strip 120 is bonded to the limiting strip 011, the inner fixing strip 110 Adhere to the opposite side of the limit strip 011, the two ends of the inner fixing strip 110 and the outer fixing strip 120 are cross-covered on the outside of the insulating layer 010, and the outer fixing strip 120 is bonded with a connecting piece 130. The fixing ring 100 also includes two side retaining rings 140, and the two side retaining rings 140 are both bonded to the outside of the insulating layer 010. The left and right ends of the central part of the inner fixing strip 110 and the outer fixing strip 120 are fixed to the inside of the two side retaining rings 140. The inner fixing strip 110, the outer fixing strip 120 and the connecting piece 130 can be assembled into a hollow cylinder with the same cross section as the side retaining ring 140;

[0049] When the outdoor cable is put into use normally, the two ends of the outdoor cable can be directly connected to the circuit, and then the current connection work is completed through the cable core 000; when the cable needs to be installed in a certain position, the connecting piece 130 can be cut so that both ends of the inner fixing strip 110 and the outer fixing strip 120 can move freely, such as Fig.10 As shown, the fixing screws can then be used to pierce and pass through the corresponding inner fixing strip 110 and the outer fixing strip 120 and fix them at the said position, thereby completing the fixing work of the outdoor cable; since the inner fixing strip 110 and the outer fixing strip 120 are both bonded to the insulating layer 010, the outdoor cable can be prevented from moving after the fixing screws fix the two ends of the inner fixing strip 110 and the outer fixing strip 120 at the corresponding positions. At the same time, since there are no screw holes on the inner fixing strip 110 and the outer fixing strip 120, the fixing screws directly pierce the inner fixing strip 110 and the outer fixing strip 120 during installation and fix them at the corresponding positions, thereby ensuring that the outdoor cable will not be pressed too tight during fixed installation, resulting in damage. At the same time, the insulating layer 010 can further provide protection for the cable core 000, thereby preventing the cable core 000 from being directly exposed to the outside after the inner fixing strip 110 and the outer fixing strip 120 are opened;

[0050] At the same time, the fixing ring 100 can provide a fixing effect while protecting the outside of the outdoor cable. When the user sets the outer fixing strip 120 on the outside when fixing the cable, since the outer side of the outer fixing strip 120 is flush with the outer side of the rubber protective layer 020, the outer surface of the cable can remain smooth. When the cable is subjected to a large area of ​​pressure, the fixing ring 100 under pressure can provide a higher supporting force than the rubber protective layer 020, thereby ensuring that the cable core 000 will not be deformed by pressure. At the same time, the fixing ring 100 is used for fixing, which can reduce the space waste caused by installing additional mounting blocks.

[0051] At the same time, since only the center of the inner fixing bar 110 and the outer fixing bar 120 are fixed on the insulating layer 010, the inner fixing bar 110 and the outer fixing bar 120 can change the splicing form according to the installation position angle when they are spliced ​​and fixed, thereby meeting the installation requirements generated by different installation positions or installation angles, and ensuring that the outdoor cable can be installed normally;

[0052] Secondly, since there are multiple fixing rings 100 evenly arranged on the outdoor cable, that is, a fixing ring 100 is arranged at a certain distance, the outdoor cable can be fixed and installed over a long distance through multiple fixing rings 100 when needed. When not needed, since there is no need to cut the connecting piece 130, the inner fixing strip 110 and the outer fixing strip 120 inside the fixing ring 100 can be kept in a covered state, thereby continuously providing protection for the outdoor cable and keeping the outdoor cable's own power transmission unaffected. When the outdoor cable needs to be retracted, the outdoor cable can also be directly curled and coiled without the need for additional retraction and storage installation devices. When installation is required, it can also be directly installed with universal screws, thereby improving the convenience of outdoor cable installation.

[0053] like Figure 8-10 As shown:

[0054] The inner fixing strip 110 and the outer fixing strip 120 are made of thin metal sheets; the thin metal sheets can be easily deformed as required under the operation of the user, thereby meeting the installation requirements of different installation positions. At the same time, the thin metal sheets can provide a certain rigidity and can maintain a certain shape when not subject to external force. When the installation position is too narrow or loose, such as when it is necessary to install the cable at an acute angle tip position less than 90°, only the outer fixing strip 120 on the outside can be opened, and the cable can be installed through the outer fixing strip 120. At this time, the inner fixing strip 110 can maintain the shape of being wrapped on the outside of the insulating layer 010, further protecting the cable core 000 inside the insulating layer 010, and also preventing the connecting piece 130 from being accidentally cut, which causes the inner fixing strip 110 or the outer fixing strip 120 to open naturally.

[0055] like Fig. 9 As shown:

[0056] The connection sheet 130 is provided with a cutting line 131 , so that the user can find the cutting position on the connection sheet 130 easily, and the cutting line 131 can provide convenience for the user to cut the connection sheet 130 .

[0057] like Figure 6 As shown:

[0058] The outer diameter of the side retaining ring 140 is equal to the inner diameter of the inner shell 210, and the inner diameter of the half hoop 240 is larger than the outer diameter of the insulating layer 010; thus, during the production and processing of the outdoor cable, the half hoop 240 can slide on the outside of the insulating layer 010 and push the side retaining ring 140 to move; at the same time, when the semi-finished cable enters the inner shell 210, a closed space can be formed between the inner shell 210, the insulating layer 010 and the two fixing rings 100, thereby ensuring that the molten rubber will not overflow from both ends of the inner shell 210.
