Or, the locking member 3 is provided with a countersunk head screw hole, the connecting member 2 is provided with a threaded hole at the corresponding position, and the locking member 3 and the connecting member 2 are fixed by passing a screw through the countersunk head screw hole and the threaded hole.

In the specific application of the method, the adhesive is coated on the surface of the substrate,

the track 1 is formed by splicing a steel rail 14 of I-shaped steel and L-shaped angle steel and can also be integrally formed. The side face of the i-shaped steel is covered with the opening side of the L-shaped angle steel, the L-shaped angle steel (the L-shaped angle steel forms the outer wall of the connecting piece mounting area) and the i-shaped steel form a connecting piece mounting area (as shown in fig. 7, the connecting piece mounting area is of a triangular groove structure), a first notch 12 is formed in the L-shaped angle steel, and a second notch is formed in the end portion of the first notch 12, specifically as shown in fig. 7.

Connecting piece 2 adopts the slider structure, and the slider adopts the triangular prism structure, and for the ease of locking retaining member 3 is to connecting piece 2, two inclined planes of connecting piece 2 all set up threaded hole. One end of each slider is provided with a connecting end which is of a plate-shaped structure, and the plate-shaped structures of the sliders on the two adjacent tracks 1 are arranged in a staggered mode, so that the plate-shaped structures can be overlapped when the two adjacent sliders are connected with each other and can be locked by the pin shaft 22. If the connecting ends can be connected by adopting plates with L-shaped structures; or one connecting end adopts a U-shaped clamping piece with a groove-shaped structure, the other connecting end adopts a plate-shaped piece, and the plate-shaped piece is inserted into a groove opening of the U-shaped clamping piece and is fixed by a screw and a pin shaft 22, so that the fixed connection of the two adjacent rails 1 is realized. The shape and the size of the non-connecting ends of the sliding blocks are consistent so as to ensure that the external dimension specifications of two adjacent tracks 1 are consistent; meanwhile, the size of the sliding blocks in the two adjacent tracks 1 is slightly smaller than that of the mounting area of the connecting piece, so that the sliding blocks can normally slide and cannot turn over.

The triangular part at the small end of the slide block is provided with a cover plate, so that the cover plate part is consistent with the external dimension of the triangular structural part of the steel rail 14, and the dimensional specifications of the two inclined surfaces are guaranteed to be consistent.

When moving to the right, as shown in fig. 9, the cover plate is caught by the rail 14 at point B and moves to the right limit position, so that the limit distance of the track 1 can be adjusted by adjusting the length of the triangular groove and the length of the cover plate.

Because the two connecting pieces 2 are connected through the pin shaft 22, the track 1 can realize displacement and steering in the direction parallel to the track 1, and because gaps exist between the sliding blocks and between the sliding blocks and the steel rails 14, steering at a slight angle inconsistent with the direction of the track 1 can be realized, so that the moving range of the track 1 is greatly increased.

The technical effects that it can realize are as follows: compare traditional track rigid, this application track can freely stretch out and draw back, can follow the user demand extension after the installation or shorten, and angle regulation simultaneously compares original rigid structure, and this track is more close to flexible construction, and environmental suitability strengthens greatly. Inside slider structure embedding rail, the apron was added to the top, prevented on the one hand to turn on one's side, and on the other hand can guarantee that surface dimensions is unanimous, guarantees whole surface structure's uniformity. Compared with the common I-steel rail, the structure of V-shaped structure is added on the upper portion of the rail, the contact surface between the rail and the wheels on the device can be increased, and the device on the upper portion can run more stably. The steel rail, the sliding block and the cover plate are combined, so that the running position can be limited on one hand, and the steel rail, the sliding block and the cover plate can be detached at any time when the steel rail, the sliding block and the cover plate are detached; compared with the common I-steel rail, the structure of V-shaped structure is added on the upper portion of the rail, the contact surface between the rail and the wheels on the device can be increased, and the device on the upper portion can run more stably.

The embodiment solves the problems that the splicing difficulty between the rails is large, the cost is high, and the steering cannot be performed after the rail is installed. V-shaped angle steel is welded on a common I-shaped steel structure, and a switching structure is added in the middle, so that the splicing of the rails is realized, the installation is simple, and the processing cost is low. And for traditional track type, the mechanism of this application can be according to the use occasion, and real-time extension, shrink and the turning to that realizes the track compare traditional track, and the adaptation face is wider.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
