Description

Technical Field

[0001] The invention relates to the technical field of switch cabinet assembly, in particular to a switch cabinet wire hole edge toothed wire protection sleeve installation device. Background Art

[0002] During the assembly of the switch cabinet, in order to prevent the wires from being scratched by the thin-walled edge of the wire hole, it is necessary to install an insulating toothed wire cover on the edge of the wire hole, such as Figure 1 As shown. The toothed wire guard can be cut according to the actual length of use. Due to its strong flexibility and convenient cutting, it is widely used at this stage. During installation, thanks to its own toothed structure, it can adapt to edges of different curvatures and angles. It is also because of its own toothed structure that it cannot be fastened quickly during installation, especially for smaller wire holes. It often takes manual labor in multiple stages to complete the installation of the entire wire guard teeth. The process is cumbersome and boring, and the efficiency is low. When the hands are buckled and pressed on the toothed wire guard, they will accidentally bump into the sharp edges of the wire holes, causing cuts to the hands. The work efficiency lags seriously behind other processes. In the prior art, Chinese patent CN214626191U discloses a toothed protective belt that is easy to install, claiming that it can achieve the effect of "facilitating component installation during installation, eliminating the need for manual alignment, and improving installation efficiency". In essence, it is only achieved by providing a protruding limit portion 23 in the cavity of the wire guard, and clamping the edge of the sheet metal through the limit portion 23 to reduce the burden of manual alignment. However, this advantage is only suitable for wire holes with sufficient space and size. The wire holes in the switch cabinet are often smaller than a fist, and are mostly waist-shaped holes. Therefore, the above patent still cannot fundamentally solve the problem of inconvenient installation of the wire guard in the wire hole of the switch cabinet. In addition, patent document CN201656362U discloses a wire guard tooth, which is essentially still achieved by providing a protrusion 50 to clamp the sheet metal. Due to the protrusions 50 arranged crosswise on the left and right, it is difficult for the wire guard to get stuck on the edge of the sheet metal. This will produce extremely unfavorable factors for the buckling of the wire guard tooth, and will further reduce the installation efficiency.

[0003] Therefore, a toothed wire grommet installation device is provided, especially for the installation of wire grommet on the edge of wire hole in switch cabinet assembly. The device can be operated quickly, and the wire grommet can be quickly aligned and pressed to finally be buckled on the edge of the wire hole. It is simple and fast, and also avoids direct contact between human hands and the edge of sheet metal, which is safe and reliable. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a device for installing a toothed wire guard at the edge of a switch cabinet wire hole, which effectively solves the problems of low installation efficiency of the wire guard at the edge of the wire hole, serious lag behind production demand, and easy cuts on hands in the existing switch cabinet assembly process.

[0022] An elastic steel bar 6 is fixed on the right side of the hand roller 1, and the right end of the elastic steel bar 6 extends to the upper right, and a rotatable disk 7 is provided on the lower side of the right end of the elastic steel bar 6. A tooth structure is provided on the front and rear end surfaces of the disk 7, and a rotatable rolling gear 8 is provided on the lower side of the disk 7. An annular groove 9 is provided on the outer edge of the rolling gear 8, and the edge of the lower end of the disk 7 is placed in the annular groove 9. The tooth structure on the front and rear end surfaces of the disk 7 is meshed with the rolling gear 8, and when the rolling gear 8 rotates, the tooth structure can drive the disk 7 to rotate; mounting plates 10 are fixed on the front and rear sides of the right end of the elastic steel bar 6, and the disk 7 and the rolling gear 8 are both rotatably mounted on the mounting plate 10.

[0023] In order to enable the device to rotate around the wire hole once when installing the wire guard, the right end of the elastic steel bar 6 is curled upward to form a ring, and there is a gap between the right end of the elastic steel bar 6 and the disk 7, and the length of the gap is slightly greater than the thickness of the side wall of the mouthguard.

[0024] In order to ensure that the trumpet-shaped ends of the two cylinders 5 can open the wire sheath, a U-shaped plate 11 is provided in the cavity of the cylinder 5, the U-shaped plate 11 is fixed to the end of the longitudinal axis 3, a rotatable wheel 12 is provided in the U-shaped plate 11, a gear ring 13 is fixed on the inner wall of the cylinder 5, a transmission gear 14 coaxial with the wheel 12 is fixed to the end of the central axis of the wheel 12, the two wheels 12 in the same cylinder 5 are placed on both sides of the corresponding gear ring 13, the wheel 12 rolls and drives the gear ring 13 to rotate through the transmission gear 14 and then drives the cylinder 5 to rotate; the edge of the wheel 12 extends out of the cylinder 5.

[0025] In order to ensure that the rolling of the wheel 12 can drive the cylinder 5 to rotate, a rubber layer is provided on the surface of the wheel 12.

[0026] In order to make the rolling wheel 2 fit better with the outer side of the cable sheath and ensure that the entire device can move along the edge of the cable hole without deflection, annular protrusions are provided at both ends of the rolling wheel 2.

[0027] It is worth noting that a rubber ring can be arranged inside the annular groove 9 on the outer edge of the rolling gear 8 to ensure that the rolling gear 8 can drive the disc 7 to rotate, so as to ensure timely feeding and avoid unnecessary pulling; the tooth shape of the rolling gear 8 and the tooth shape of the tooth structure on both end surfaces of the disc 7 are both matched with the edge tooth shape of the toothed wire guard, which can ensure that when the disc 7 rotates, it can drive enough wire guards to move toward the rolling wheel 2; the elastic steel bar 6 is in a slightly downward arc shape, and the elastic steel bar 6 is made of flat round steel bars or long steel sheets. The elastic steel bar 6 can swing up and down but not back and forth.

[0028] One side edge of the wheel 12 extends out of the cavity of the cylinder 5, so that the friction between the cylinder 5 and the sheet metal is reduced, which can ensure that the wheel 12 can ensure its own rotation while also providing sufficient power to drive the cylinder 5 to rotate.

[0029] A bearing is installed between the rolling wheel 2 and the hand roller 1 ; a bearing is installed between the cylinder 5 and the longitudinal axis 3 .

[0030] Before use, place the device in the wire hole, then move the two longitudinal axes 3 to the side away from each other, and place the sheet metal between the two cylinders 5, loosen the longitudinal axis 3, and the longitudinal axis 3 is close to the sheet metal under the action of the torsion springs at the ends of the multiple connecting rods 4. The two cylinders 5 clamp the sheet metal, and one end of the protective cover is passed through the disc 7 to the left and placed between the rolling wheel 2 and the cylinder 5, and the upper edge of the cylinder 5 is placed in the cavity of the wire protection cover. Since the ends of the cylinders 5 that are close to each other are trumpet-shaped, the wire protection cover can be stretched open; when using, hold the two ends of the hand roller 1 with both hands, and move them to the right at the same time along the edge of the wire hole, and move In the process, the wheel 12 rotates and rolls along the surface of the sheet metal, the wheel 12 drives the transmission gears 14 at both ends to rotate, the transmission gear 14 drives the cylinder 5 to rotate through the gear ring 13, the edge of the cylinder 5 fits with the surface of the sheet metal to ensure that the wire protection sleeve here is stretched, at the same time, the elastic steel bar 6 presses the rolling gear 8 through the mounting plate 10, the rolling gear 8 rolls along the edge of the wire hole, the rolling gear 8 drives the disk 7 to rotate through the tooth structure on the disk 7, the rotation of the disk 7 drives the wire protection sleeve to move through the tooth structure at both ends to realize loading; after the device rotates one circle along the wire hole, it cuts at the appropriate position and the installation is completed.

[0031] The elastic steel bar 6 is made of a flat round steel bar sheet, so that the elastic steel bar 6 can swing up and down but not forward and backward. The elastic steel bar 6 provides a sufficiently large pressure for the rolling gear 8 so that it obtains sufficient friction, thereby ensuring that the rolling gear 8 can provide sufficient rotational force for the disc 7. At the same time, due to the presence of the elastic steel bar 6, when the device moves to a curve, the elastic steel bar 6 can automatically change direction, thereby ensuring that the entire device can only move along the edge of the wire hole.

[0032] When the device is in use, two hands are moved simultaneously, and the two cylinders 5 are clamped on the sheet metal. Even if there is a pause in the middle, the device will not fall off easily. In addition, moving both hands simultaneously can well control the pressing force of the rolling wheel 2 on the wire sleeve to prevent it from being deflected.

[0033] The present invention is essentially to "lift" the wire sheath first, and then press the wire sheath onto the edge of the wire hole by the rolling wheel 2. The wire sheath is in the press buckle, and its two sides are downward along the trumpet-shaped structure at the end of the cylinder 5. When the cylinder 5 leaves, the two sides of the wire sheath clamp the sheet metal toward the middle, which goes with the flow and is easy to understand.

[0034] The invention has an ingenious structure. The toothed structure of the toothed wire guard sleeve is used to guide the wire guard sleeve to the top of the edge plate of the sheet metal. Then, the two sides of the wire guard sleeve are spread open and pressed downward, so that the wire guard sleeve can be accurately mounted on the edge of the wire hole without repeated centering. The invention is simple to operate and has high installation efficiency. At the same time, it also avoids contact between the hands and the edge of the wire hole, avoids cuts, ensures efficiency and provides safety protection for workers.
