Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, specifically to a device for roughening the cable sheath. Background Technology

[0002] During cable installation, to enhance the bond strength between the cable and sealant, sealing tape, or heat shrink tubing, the cable sheath is typically roughened. This process creates a roughened structure on the sheath, breaking up the smooth layer and increasing the bonding area, improving adhesive wetting, and enhancing the cable sheath's friction. However, most existing roughening methods involve installers manually scraping the cable sheath with a file. This method is not only cumbersome but also prone to uneven roughening due to the difficulty in maintaining consistent pressure. Some areas may be over-roughened, damaging the cable sheath's integrity and reducing its effective thickness and pressure resistance; while other areas may be under-roughened, failing to meet the required bonding area and friction. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a cable sheath roughening device, which is not only easy to operate, but also ensures the uniformity of the roughened structure.

[0004] The present invention adopts the following technical solution.

[0005] A cable sheath roughening device includes a C-shaped base frame, a movable component adjustablely connected to the top of the base frame, and a roughening cutter detachably connected to the bottom of the movable component.

[0006] The roughening tool includes a mounting base, the bottom end of which has a mounting cavity. A movable block is slidably connected inside the mounting cavity. A first spring is connected between the movable block and the mounting cavity. The first spring causes the movable block to tend to move downward. Multiple pointed protrusions are evenly distributed at the bottom end of the movable block.

[0007] The bottom of the mounting base is rotatably connected to the left and right sides of the mounting base, and the bottom of the base frame is provided with a V-shaped clearance cavity, and the top of the clearance cavity is rotatably connected to the left and right sides of the clearance cavity.

[0008] Furthermore, the moving component includes a vertically extending moving frame and a screw, the screw being rotatably connected to the moving frame, and the top end of the screw extending above the moving frame and having a knob provided thereon;

[0009] The top of the base frame is provided with a limiting seat, and the limiting seat has a limiting hole that is slidably connected to the movable frame. The limiting seat is provided with a locking component that acts on the screw.

[0010] Furthermore, the locking assembly includes a swing arm hinged to the limiting seat, the first end of the swing arm extending to the outside of the limiting seat and having a pressing part, and the second end of the swing arm having a locking block capable of engaging with the screw.

[0011] A first spring is connected between the swing arm and the limiting seat. The first spring causes the swing arm to tend to engage the locking block with the screw.

[0012] Furthermore, a second spring is connected between the movable frame and the limiting seat, and the second spring causes the movable frame to tend to move upward.

[0013] Furthermore, the bottom of the movable frame is provided with a positioning wall, and the top of the mounting base is provided with a positioning block. The positioning wall and the positioning block are respectively provided with a first positioning hole and a second positioning hole that cooperate with each other. A locking component is connected between the first positioning hole and the second positioning hole.

[0014] Furthermore, the locking assembly includes a locking pin, the first end of which is provided with an outwardly expanding limiting shoulder, the second end of which is provided with a storage cavity, the side wall of which is provided with a mounting hole, a locking ball being movably connected in the mounting hole, and a second spring piece connecting the locking ball and the storage cavity, the second spring piece causing the locking ball to tend to protrude from the outer side wall of the locking pin.

[0015] Furthermore, the top of the movable block is provided with a connecting post, and the connecting post has a vertically extending waist hole, and the mounting base is threaded with a screw that passes through the waist hole.

[0016] The beneficial effects of this utility model are as follows:

[0017] When roughening the cable sheath is required, the installer first places the base frame outside the cable and adjusts the moving assembly so that the first roller on the roughening cutter and the second roller on the base frame are pressed against the cable. Next, the installer rotates the base frame circumferentially along the cable. This allows the sharp protrusions on the roughening cutter to scrape the cable sheath, making the entire process relatively convenient. Furthermore, the elastic force of the first spring ensures that the pressure exerted by the protrusions on the cable sheath remains within a stable range, which helps ensure the uniformity of the roughened structure.

[0039] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0040] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0041] As shown in the attached figure, a roughening device for the outer sheath of a cable 6 includes a C-shaped base frame 1, a movable component 2 that is adjustablely connected to the top of the base frame 1, and a roughening cutter 3 that is detachably connected to the bottom of the movable component 2.

[0042] The roughening tool 3 includes a mounting base 31, and a mounting cavity 311 is provided at the bottom end of the mounting base 31. A movable block 32 is slidably connected in the mounting cavity 311. A first spring 33 is connected between the movable block 32 and the mounting cavity 311. The first spring 33 causes the movable block 32 to have a downward tendency. A plurality of pointed protrusions 321 are evenly distributed at the bottom end of the movable block 32.

[0043] The bottom left and right sides of the mounting base 31 are respectively rotatably connected to the first roller 34, and the bottom of the base frame 1 is provided with a V-shaped clearance cavity 11. The top left and right sides of the clearance cavity 11 are respectively rotatably connected to the second roller 12.

[0044] When roughening the outer sheath of cable 6 is required, the installer first places the base frame 1 on the outside of cable 6 and adjusts the moving assembly 2 so that the first roller 34 on the roughening cutter 3 and the second roller 12 on the base frame 1 respectively press against cable 6, as shown in the attached diagram. Figure 1 As shown. Under the elastic force of the first spring 33, the pointed protrusion 321 at the bottom of the moving block 32 applies a compressive force within a predetermined range to the cable 6 sheath. Then, the installer operates the base frame 1 to rotate circumferentially along the cable 6, causing the pointed protrusion 321 to scrape the cable 6 sheath.

[0045] The rolling action of the first roller 34 and the second roller 12 can effectively reduce the frictional resistance that the base frame 1 experiences during rotation, except for that from the protrusion 321.

[0046] In this embodiment, the movable block 32 is square-shaped. In other embodiments, the movable block 32 may also be cylindrical.

[0047] Preferably, the moving component 2 includes a vertically extending moving frame 21 and a screw 22, the screw 22 being rotatably connected to the moving frame 21, and the top end of the screw 22 extending above the moving frame 21 and having a knob 23.

[0048] The top of the base frame 1 is provided with a limiting seat 13, and the limiting seat 13 is provided with a limiting hole that is slidably connected to the movable frame 21. The limiting seat 13 is provided with a locking component 4 that acts on the screw 22.

[0049] Preferably, the locking assembly 4 includes a swing arm 41 hinged to the limiting seat 13. The first end of the swing arm 41 extends to the outside of the limiting seat 13 and is provided with a pressing part 42. The second end of the swing arm 41 is provided with a locking block 43 that can engage with the screw 22.

[0050] A first spring plate 44 is connected between the swing arm 41 and the limit seat 13. The first spring plate 44 makes the swing arm 41 tend to drive the locking block 43 to engage with the screw 22.

[0051] When the locking block 43 engages with the screw 22, the movable frame 21 is locked and cannot move directly upwards. If it is necessary to roughen the sheath of the cable 6, the installer can press the pressing part 42 to cause the swing arm 41 to drive the locking block 43 to disengage from the screw 22, thereby unlocking the movable frame 21. At this time, the installer can quickly move the movable frame 21 upwards to increase the distance between the roughening tool 3 and the clearance cavity 11, making it easier to place the base frame 1 on the outside of the cable 6. Next, the installer pushes the movable frame 21 downwards until the first roller 34 on the roughening tool 3 and the second roller 12 on the base frame 1 respectively press against the cable 6. Then, the installer releases the pressing part 42, and under the action of the first spring piece 44, the swing arm 41 drives the locking block 43 to re-engage with the screw 22, thereby locking the movable frame 21. Finally, the installer turns knob 23, and by using the meshing action of screw 22 and locking block 43, screw 22 drives moving frame 21 to move further downward, thereby increasing the squeezing force of the tip 321 on the cable sheath 6 and ensuring the effect of subsequent roughening treatment.

[0052] Preferably, a second spring 24 is connected between the movable frame 21 and the limiting seat 13, and the second spring 24 causes the movable frame 21 to tend to move upward. When the installer presses the pressing part 42, causing the swing arm 41 to disengage the locking block 43 from the screw 22, the second spring 24 then drives the movable frame 21 to move upward. This design greatly facilitates the operation of the installer.

[0053] Preferably, the bottom of the movable frame 21 is provided with a positioning wall 211, and the top of the mounting base 31 is provided with a positioning block 312. The positioning wall 211 and the positioning block 312 are respectively provided with a first positioning hole and a second positioning hole that cooperate with each other. A locking component 5 is connected between the first positioning hole and the second positioning hole.

[0054] Preferably, the locking component 5 includes a locking pin 51. The first end of the locking pin 51 is provided with an outwardly expanding limiting shoulder 511. The second end of the locking pin 51 is provided with a storage cavity. The side wall of the storage cavity is provided with a mounting hole. A locking ball 52 is movably connected in the mounting hole. A second spring piece 53 is connected between the locking ball 52 and the storage cavity. The second spring piece 53 makes the locking ball 52 tend to protrude from the outer side wall of the locking pin 51.

[0055] In this embodiment, positioning walls 211 are provided on the left and right sides of the bottom end of the mobile frame 21.

[0056] With the positioning wall 211 and the positioning block 312 connected, the locking pin 51 passes through the first positioning hole and the second positioning hole, and the limiting shoulder 511 of the locking pin 51 is close to the positioning wall 211 on the left side. At the same time, the locking ball 52 protrudes from the outer wall of the locking pin 51 under the action of the second spring piece 53 and is close to the positioning wall 211 on the right side.

[0057] When it is necessary to remove the roughening tool 3 from the moving frame 21, the user can press the second end of the locking pin 51 to retract the locking ball 52 into the locking pin 51, and then pull the locking pin 51 out from the first positioning hole and the second positioning hole, thereby removing the roughening tool 3 from the moving frame 21.

[0058] Preferably, the top of the movable block 32 is provided with a connecting post 322, the connecting post 322 is provided with a vertically extending waist hole, and the mounting base 31 is threaded with a screw 35 passing through the waist hole.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
