DETAILED DESCRIPTION

[0028] Example 1

[0029] A kind of communication optical fiber laying device, including two single base body 1 and optical fiber disc 3, the two round edges of optical fiber disc 3 are placed on two single base body 1.

[0030] Among them, the single base body 1 is welded by inclined plane 4 and groove 5.

[0031] Wherein, the notch of the groove 5 is arc-shaped, and the inner side of the groove 5 is provided with a U-shaped bearing groove 8, which is symmetrically distributed at the inner side of both sides of the groove 5.

[0032] Wherein, the U-shaped bearing groove 8 is U-shaped, and the notch is arc-shaped.

[0033] Wherein, the U-shaped bearing groove 8 is installed with a support rotating structure composed of a bearing 6 and a roller 7, and the roller 7 extends out of the connecting shaft connected with the bearing 6 at both ends.

[0034] Wherein, the surface of the roller 7 is provided with anti-skid lines.

[0035] Wherein, the middle of one side of the groove 5 is provided with a lever mounting hole 9, and the lever mounting hole 9 penetrates one side of the groove 5.

[0036] Wherein, the lever mounting hole 9 is provided with a lever 2.

[0037] Wherein, the lever 2 includes a lever support rod 10, a lever push disc 12, a lever disc connecting groove 13, and a lever support rod hole 14 close to the force point, the lever push disc 12 is connected with the lever disc connecting groove 13 at one end of the lever 2 through rivets, the lever support rod 10 passes through the lever support rod hole 14, the lever 2 passes through the lever mounting hole 9, and the lever support rod 10 is fixed in the lever mounting hole 9 through the lever support rod fastening plug 11.

[0038] Wherein, the lever 2 further includes a lever extension screw hole 15 arranged in front of the lever force point.

[0039] Two identical single base bodies are placed in front of the fiber disc 3, the fiber disc 3 is pushed onto the laying device through the slope 4, so as to support the fiber disc 3, and the fiber disc 3 can realize in-place rolling of the fiber disc 3 through the roller 7 connected with the bearing 6. Since the fiber disc 3 is always in a relative rotating state with the single base body when the fiber disc 3 is on the laying device, when the fiber disc 3 needs to be removed or replaced, the fiber disc 3 is lifted up through the lever 2, and the fiber disc 3 is pushed out of the single base body by manual pushing.

[0040] The functions of the components in the above technical solution are as follows:

[0041] Through the slope 4, the fiber disc 3 can be easily pushed into the groove 5, and the manpower can be greatly saved; through the support structure composed of the bearing 6 and the roller 7 in the groove 5, the fiber disc 3 can be supported and rotated in place in the groove 5.

[0042] The notch of the groove 5 is arc-shaped, which can make the U-shaped bearing groove 8 with the same inner diameter of the bearing 6 tangent to the groove 5, so that the U-shaped bearing groove 8, the bearing 6 and the roller 7 are arranged according to the curvature of the groove, and since four rollers 7 are installed on each base, when the number of arc radians of the fiber disc 3 is the same as the curvature of the groove (for example, the fiber disc with a radius of 70 cm designed in the utility model), the fiber disc 3 is tangent to each roller 7, when the radius of the fiber disc 3 is smaller than the radius of the groove, the fiber disc 3 is tangent to the two rollers 7 in the middle, and when the radius of the fiber disc is greater than the radius of the groove, the fiber disc 3 is tangent to the two rollers 7 on the outside, so that the utility model is suitable for the fiber disc laying requirements of various specifications.

[0043] The anti-skid pattern on the surface of the roller 7 can effectively prevent the fiber disc 3 and the roller 7 from slipping when they are rotating relative to each other; the diameter of the roller 7 is greater than the diameter of the bearing 6, so that the roller 7 is higher than the groove 5, and the fiber disc 3 will not scratch the groove 5 when it is misaligned during the laying process, thereby ensuring the smooth laying process.

[0044] The lever 2 is fixed at the lever mounting hole 9, and when it is necessary to move the fiber disc 3 out of the groove 5, the lever 2 is used to lift the fiber disc 3, since the lever disc pushing plate 12 can rotate 180° around the rivet position, the rotating lever disc pushing plate 12 can fully contact the fiber disc 3, and the maximum contact area between the lever disc pushing plate 12 and the fiber disc 3 is maintained at all times, so as to achieve the maximum friction force and avoid relative sliding, and the fiber disc 3 can be easily pushed down to the laying base by the action of horizontal external force; when the weight of the fiber disc 3 is insufficient to lift the lever 2, the extension lever can be installed by using the extension screw hole 15 of the lever, so as to achieve the most labor-saving condition.

[0045] The middle of one side of the groove 5 is the lever mounting hole 9, the lever 2 can be installed through the lever support rod 10, and the lever support rod 10 is fixed by using the lever support rod fastening plug 11, so as to ensure that the lever 2 will not be loose during use.

[0046] Embodiment 2

[0047] A fiber disc laying device base, comprising two identical single base bodies and a pair of levers 2, the base has an inclined slope 4 with a certain inclination angle, the right angle side of the inclined slope 4 is 15 cm, and the base side and the inclined side have round corners, the inside of the single base body is a groove 5 with a length of 50 cm and a width of 17.2 cm, the inclined slope 4 and one groove 5 are welded together, and a supporting rotating structure composed of a bearing 6 and a roller 7 is installed in the groove 5.

[0048] The notch of the groove 5 is an arc with a radius of 70 cm, and the inner side of the groove 5 has eight U-shaped bearing grooves 8, which are symmetrically distributed on the inner side of the two sides of the groove 5; the middle of one side of the groove 5 is the lever mounting hole 9.

[0049] The U-shaped bearing groove 8 is U-shaped, with one side serving as a baffle. The groove depth and width are the same as the diameter of the bearing 6, which is 31mm. The groove opening has a certain arc angle.

[0050] The lever mounting hole 9 passes through one side of the groove 5, at the middle position of the side of the groove 5;

[0051] The surface of roller 7 has anti-slip texture, and connecting shafts with the same inner diameter as bearing 6 extend from both ends. The diameter of roller 7 is 33mm, which is larger than the diameter of bearing 6.

[0052] Lever 2 includes lever rod 10, lever rod fastening plug 11, lever push plate 12, lever plate connecting groove 13, lever rod hole 14 near the force application point, and lever extension screw hole 15 in front of the force application point. Half of the cross-sectional space of lever rod 10 is cut off from the front part of lever rod fastening plug 11.

[0053] The lever push plate 12 is T-shaped, with a square upper push plate and a rivet hole at the bottom for connection to the lever 2 via rivets; the lever push plate 12 can rotate 180° around the rivet position.

[0054] The lever plate connecting groove 13 is concave in top view and has rivet holes inside. The lever push plate 12 is connected to the lever 2 by rivets. In addition to the connection space between the lever push plate 12 and the lever 2, there is also a certain space for the push plate to rotate.

[0055] The following is combined Figures 1-9 Further explanation of the technical solution of this utility model:

[0056] like Figure 1 As shown, an auxiliary cable laying base for an optical fiber reel includes a pair of bases 1 and a pair of levers 2. The base 1 is welded with a ramp 4 and a groove 5. The groove 5 has 8 U-shaped bearing grooves 8 inside. The U-shaped bearing grooves 8 are used to fix the support rotation structure composed of bearings 6 and rollers 7. A lever mounting hole 9 is left in the middle of one side of the groove 5 so that the lever 2 can be installed. The lever rod 10 is fixed at the lever mounting hole 9 by passing through the lever rod hole 14. The lever rod 10 is then fastened with a lever rod fastening plug 11.

[0057] The operation steps are as follows: Refer to Figure 4 and Figure 2 The two sides of the roller 7 are connected to the bearing 6 and then the bearing 6 is fixed on the U-shaped bearing groove 8 of the groove 5. Since the radius of the roller 7 is larger than the radius of the bearing 6, the roller 7 will be higher than the groove 5 after installation, so that the fiber optic tray 3 will not scrape against the groove 5 due to the offset position during the cable laying process. The threads on the roller 7 can increase the friction between the roller 7 and the fiber optic tray 3.

[0058] Reference Figure 5 andFigure 9 The lever support rod 10 is inserted through the lever support rod hole 14 of the lever 2, and then the lever support rod 10 is inserted into the lever mounting hole 9 and fixed by using the lever support rod fastening plug 11.

[0059] Referring to Figure 10 The two bases 1 are placed in parallel at a designated position, the direction of the slope 4 is adjusted to the distance between the two side disc bases 1 of the fiber disc 3 to be suitable for the width of the fiber disc 3, and the fiber disc 3 is pushed into the base groove 5 from the slope 4 by manpower to perform the laying.

[0060] Referring to Figures 6-8 The force receiving end of the lever 2 is connected to the lever push disc 12 through the lever disc connection slot 13 by using a rivet, and the force applying end is provided with a lever extension screw hole 15. In theory, the lever push disc 12 of the utility model can be rotated by 180° with the rivet position as the center, and in the actual use process, the utility model can be in full contact with the fiber disc 3 through the rotating lever push disc 12. When it is needed to move the fiber disc 3 out of the groove 5, the construction personnel step on the force applying point of the lever 2 with the foot, the lever 2 pushes the lever push disc 12 at the force receiving point, the lever push disc 12 is fully in contact with the fiber disc 3 and is pushed upward at the same time, the fiber disc 3 is lifted, and the construction personnel simultaneously apply a horizontal pushing force to the fiber disc 3, so that the fiber disc 3 can be pushed out of the laying base 1. When the fiber disc 3 is too heavy, the lever 2 is not enough to lift the fiber disc 3, and the lever extension screw hole 15 reserved at the force applying end can be used to increase the moment.

[0061] The above only describes the preferred embodiments of the utility model, and it should be noted that for ordinary skilled persons in the technical field, some improvements and modifications can be made without departing from the technical principles of the utility model, and these improvements and modifications should also be considered as the protection scope of the utility model.
