[ detailed description ] embodiments

The technical solutions of the embodiments of the present invention are explained and explained below with reference to the drawings of the embodiments of the present invention, but the embodiments described below are only preferred embodiments of the present invention, and not all embodiments. Based on the embodiments in the embodiment, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention.

In the following description, the appearances of the indicating orientation or positional relationship, such as the terms "inner", "outer", "upper", "lower", "left", "right", etc., are only for convenience in describing the embodiments and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and are not to be construed as limiting the invention.

Example 1:

referring to fig. 1 to 3, the present embodiment provides a portable device for debugging a mobile optical cable, including a vehicle body 1 and a wire spool installed on the vehicle body 1.

Two front wheel assemblies are installed at the front side of the bottom of the vehicle body 1, and two rear wheels 2 are installed at the rear side of the bottom of the vehicle body 1. The front wheel assembly is matched with the rear wheel 2 to realize the linear movement or turning of the vehicle body 1.

Wherein rear wheel 2 is the truckle, and the truckle includes third pivot and rear wheel body, and the rear wheel body rotates and installs on the third pivot, and the third pivot is fixed relative automobile body 1, so the rear wheel body can only rotate around the third pivot relative automobile body 1.

The front wheel assembly comprises a bottom plate 3, a first rotating shaft 4, a second rotating shaft 5, a wheel bracket 6 and a front wheel body 7.

The wheel support 6 is bent to form a wheel body groove at the bottom of the wheel support 6, the second rotating shaft 5 is fixed in the wheel body groove, and two ends of the second rotating shaft 5 are fixed on the side wall of the wheel body groove. The front wheel body 7 is rotatably arranged on the second rotating shaft 5, and the front wheel body 7 is limited by the side wall of the wheel body groove, so that the front wheel body 7 is prevented from being separated from the second rotating shaft 5.

The first rotating shaft 4 is perpendicular to the second rotating shaft 5, the lower end of the first rotating shaft 4 is fixed at the top of the wheel bracket 6, and the upper end of the first rotating shaft 4 is fixedly arranged on the bottom plate 3. The lower bottom surface of the vehicle body 1 is provided with a rotating groove, and the bottom plate 3 is rotatably arranged in the rotating groove, so that the front wheel body 7 can also rotate around the axis of the first rotating shaft 4 relative to the vehicle body 1. In order to prevent the bottom plate 3 from being separated from the rotating groove, a pressing plate is further arranged in the rotating groove and extruded on the bottom plate 3, and meanwhile, the pressing plate and the inner wall of the rotating groove are fixed through screws, so that the bottom plate 3 is limited in the rotating groove. Of course, the pressing force of the pressing plate on the soleplate 3 should not influence the rotation of the soleplate 3 in the rotating groove.

The lower bottom surface of the bottom plate 3 is also provided with a positioning groove which is positioned in the lateral direction of the rotating groove and used for installing a limiting plate 8. When the spacing board 8 is located the dismouting of positioning groove department, the outer wall laminating of wheel support 6 is on the spacing board 8 to the first pivot 4 of restriction rotates on bottom plate 3, and corresponding front wheel 7 receives the restriction around the rotatory degree of freedom of first pivot 4 axis for automobile body 1, and specific limited degree receives restriction such as spacing board 8 installation quantity, shape and angle each other.

For example, constant head tank quantity has two in this embodiment, and two constant head tanks separated are in the both sides in rotating the groove, and limiting plate 8 is dull and stereotyped, and when limiting plate 8 was all installed to two constant head tanks department, two relative and mutual parallel arrangement of limiting plate 8, 6 centre gripping of wheel support were between two limiting plates 8, and bottom plate 3 was unable to rotate at the rotation inslot completely this moment, and the third pivot was on a parallel with second pivot 5 this moment simultaneously. Therefore, the vehicle body 1 can move forward or backward only in a straight direction.

After the limiting plate 8 is detached from the positioning groove, the front wheel body 7 recovers the degree of freedom of rotation around the axis of the first rotating shaft 4, and at the moment, the vehicle body 1 has the degree of freedom of turning again.

In order to avoid the situation that the limiting plate 8 is separated from the positioning groove after being assembled in place, the edge of the limiting plate 8 is fixedly provided with the positioning block 9, the shape of the positioning block 9 is matched with that of the positioning groove, and when the limiting plate 8 is installed at the positioning groove, the positioning block 9 is filled in the positioning groove and is locked with the inner wall of the positioning groove through screws. Utilize constant head tank inner wall and locating piece 9 cooperation simultaneously, can effectively avoid limiting plate 8 to rotate on automobile body 1 to the limiting displacement of limiting plate 8 to wheel support 6 has been guaranteed.

In other embodiments, also can adopt and set up the external screw thread at discoid locating piece 9's edge, set up the form of internal thread at the constant head tank inner wall, the spacing board 8 dismouting is in constant head tank department to the form of internal thread and external screw thread cooperation to simplify the dismouting process of spacing board 8.

The wire spool in this embodiment includes a central shaft 10, a cylindrical body 11, and a partition ring 12, and the central shaft 10 is fixed to the vehicle body 1, thereby mounting the wire spool on the vehicle body 1. The central shaft 10 penetrates the cylindrical body 11 and is aligned with the central shaft 10 of the cylindrical body 11, thereby controlling the cylindrical body 11 to be rotatably arranged on the central shaft 10. The cylinder 11 can rotate around the central shaft 10. The separating ring 12 is sleeved in the middle of the cylinder 11 and fixed with the outer wall of the cylinder 11, and the separating ring 12 divides the cylinder 11 into two winding areas. The two winding areas can be used for placing cables with different specifications respectively.

Preferably, the two ends of the cylinder 11 are sleeved with the separating rings 12, and the separating rings 12 at the two ends of the cylinder 11 are also fixed with the outer wall of the cylinder 11. Therefore, the cable can be taken out only by rotating the cylinder 11, and cannot be taken out directly from both ends of the cylinder 11.

Example 2:

the present embodiment is different from embodiment 1 in that a handle is attached to a vehicle body. The part of automobile body is the cylinder, is provided with the external screw thread on this cylinder outer wall, and the fretwork forms the cell body in the middle of the handle, is provided with the internal thread on the cell body inner wall, internal thread and external screw thread threaded connection to make handle and cylinder telescopic setting relatively, handle movable mounting is on the automobile body, and utilizes the auto-lock ability of screw thread, stabilizes the position of handle on the automobile body, thereby adapts to different user heights.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
