Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic drawings, which illustrate the basic structure of the invention only in a schematic way, and thus show only the components that are relevant to the invention, and the directions and references (e.g., upper, lower, left, right, etc.) may be used only to help describe the features in the drawings. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the claimed subject matter is defined only by the appended claims and equivalents thereof.

An integrated centering rod as shown in fig. 1 is a preferred embodiment of the present invention. Integrated form centering rod includes sleeve 4, telescopic link 2, bolt 1 and mount pad 3, and telescopic link 2 is flexible to be set up on sleeve 4, and it has a plurality of flexible locating holes to open on telescopic link 2, and mount pad 3 is fixed on sleeve 4, and it has the mounting hole to open on mount pad 3, and bolt 1 sets up in the mounting hole and locks sleeve 4 and telescopic link 2 through the locating hole. When the centering rod is used, the bolt 1 is extracted, the sleeve 4 and the telescopic rod 2 are unlocked, the telescopic rod 2 is adjusted relative to the position of the sleeve 4, the bolt 1 is inserted after the required position is reached, the telescopic positioning holes of the mounting seat 3 and the telescopic rod 2 are locked by the bolt 1, and the mounting seat 3 is fixed on the sleeve 4, so that the position adjustment of the centering rod sleeve 4 and the telescopic rod 2 is realized.

As shown in fig. 2 to 7, the handbook of the centering rod is directly installed through the mounting seat 3. The handbook is directly fixed on the handbook directly connecting bracket 5. The mounting base 3 is respectively provided with an insertion hole 8 and a handbook hole 9, the insertion hole 8 and the handbook hole 9 are staggered to form an overlapping space, and an included angle formed by the insertion hole 8 and the handbook hole 9 at the position of the overlapping space is 90 degrees. I.e. the hole 8 and the pad hole 9 are arranged in the direction perpendicular to each other. The inside of the handbook hole 9 is inserted with a handbook direct-connecting bracket 5, and the inside of the inserting hole 8 is inserted with an inserting buckle 6. At the overlapping space, the insert buckle 6 has a mating surface with a press-fit with the direct-connection bracket 5 of the handbook. The embodiment realizes the plugging positioning of the handbook direct-connecting bracket 5 and the mounting seat 3 through the matching at the position.

Specifically, in this embodiment, the direct connecting bracket 5 for the handbook is a cylindrical structure, the cylindrical structure has an annular groove 10 corresponding to the concave outer peripheral surface in compression joint with the plug-in buckle 6, and the contact surface between the plug-in buckle 6 and the direct connecting bracket 5 for the handbook is an arc surface 13 adapted to the annular groove 10. An elastic member is pressed between the bottom of the inserting buckle 6 and the bottom of the inserting hole 8, the elastic member is preferably a spring 11, one end of the spring 11 is connected with the inserting buckle 6, and the other end is connected with the bottom of the inserting hole 8.

Meanwhile, in order to simplify the insertion process, the end of the handbook straight-connecting bracket 5 inserted into the handbook hole 9 is provided with a guide transition surface 7 matched with the cambered surface 13 of the insert buckle 6, and the guide transition surface 7 is a bevel. Through the design of direction transition face 7, when inserting the handbook directly link bracket 5, the inclined plane contacts with cambered surface 13, through applying the force to handbook directly links bracket 5, this force has the component to cambered surface 13 through direction transition face 7 is exerted, can extrude cambered surface 13 for the elastic component receives the extrusion, thereby promotes eye-splice 6, and handbook directly links bracket 5 can peg graft in place, realizes the installation simplified operation.

In assembling, the insert buckle 6 and the spring 11 are first set in the insertion hole 8. Directly link bracket 5 with the handbook and aim at handbook hole 9, insert handbook and directly link bracket 5, the handbook directly links 7 extrusion buckles 6's cambered surface 13 of direction transition face of bracket 5, buckles 6 are pushed spring 11 atress and are extruded the shrink, handbook directly links bracket 5 and pegs graft and target in place, ring channel 10 and cambered surface 13 crimping cooperation, loosen handbook and directly link bracket 5, spring 11 is outside bullet with buckle 6 under the spring action, the handbook directly links ring channel 10 of bracket 5 then with the 13 cooperation crimps of cambered surface of buckle 6, handbook directly links

bracket

5 and 3 effective lockings.

When the handbook needs to be removed, the inserting buckle 6 is pressed, the inserting buckle 6 pushes and extrudes the spring 11 along the inserting hole 8, the annular groove 10 is separated from the cambered surface 13 for unlocking, the handbook directly-connected bracket 5 can be pulled out from the handbook hole 9 at the moment, and the handbook is taken down.

As shown in fig. 8, in the present embodiment, in order to prevent the insertion buckle 6 from being released from the insertion hole 8, the insertion buckle 6 has a stopper hook 14 which is in hooking engagement with the inner wall of the insertion hole 8 of the mounting seat 3. In the process that the spring 11 springs the inserting buckle 6 outwards, the limiting hook 14 is hooked with the inner wall of the inserting hole 8, and the spring 11 can be prevented from springing the inserting buckle 6 out of the inserting hole 8. Accordingly, the insertion of the plug 6 into the insertion hole 8 is performed such that the plug 6 has an outer edge 12 pressed against the end surface of the insertion hole 8 corresponding to the end surface of the insertion hole 8 of the mount 3 in order to prevent the plug 6 from being excessively inserted into the insertion hole 8. The outer edge 12 can cover the end face of the insertion hole 8, so that the insertion buckle 6 is prevented from being totally sunk into the insertion hole 8 to influence normal assembly and assembly.

The integrated centering rod designed in this way is reasonable in structural design, and through the elastic locking design of the elastic inserting buckle 6, the mounting of the handbook is directly integrated on the mounting seat 3, a split type mounting bracket and a clamping mechanism are not required to be additionally designed, the handbook can be directly inserted into the mounting seat 3, and the locking and unlocking operation is carried out through the inserting buckle 6, so that the handbook mounting process is convenient and fast, meanwhile, parts are simplified, the material cost and the use cost are effectively reduced, and the good economic benefit is achieved.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
