The invention relates to a sliding track without rolling balls, which comprises a first track body, a second track body assembled in the first track body and a third track body assembled in the second track body, wherein the second track body is positioned between the first track body and the third track body, the first track body and the second track body, as well as the second track body and the third track body, are respectively in curved surface-shaped direct contact, the second track body comprises an upper arm and a lower arm, which are symmetrically arranged, each one of the upper arm and the lower arm comprises a first kinked part, a second kinked part, a third kinked part and a fourth kinked part, which are sequentially connected, arc-shaped first sliding parts are respectively formed on the edges of the junctions between the second kinked parts and the first kinked parts and in sliding contact with the third track body, and arc-shaped second sliding parts are respectively formed on the edges of the junctions between the fourth kinked parts and the third kinked parts and are in sliding contact with the first track body. All the track bodies of the sliding track without the rolling balls of the application are in curved surface-shaped direct contact, thereby not only reducing the use of the rolling balls and other elements and saving the cost, but also being firm in structure, being strong in bearing capacity and being labor-saving to slide.

The invention discloses a ramp which comprises a ramp body, wherein the ramp body is positioned beside downward steps. The ramp further comprises an anti-slip mat, and the anti-slip mat covers the ramp body. The downward resistance of the wheels of bags and suitcases is enhanced by arranging the anti-slip mat on the ramp body. Due to the fact that the anti-slip mat enhances the fiction between the wheels the bags and the suitcases and the ramp, when passengers walk down the steps, the passengers can drag the bags and the suitcases to slide downward along the ramp effortlessly and conveniently.

The invention discloses a quick positioning device and an application method thereof. The quick positioning device comprises a detection mechanism, a track rack and a centering track car. The detection mechanism is provided with a detection space and a detection axle wire. The track rack comprises a first guide rail and a second guide rail. A first limiting block and a second limiting block are separately arranged at one end of the second guide rail, two sides of the centering track car are slidably connected to the first guide rail and the second guide rail, separately, a first positioning block and a second positioning block are separately arranged on two sides of one end of the centering track car, the first positioning block and the second positioning block lean against the first limiting block and the second limiting block to be in contact for limited fit, separately, the centering track car is provided with a centering axle wire, and the distances from the first positioning blockand the second positioning block to the centering axle wire correspond to the distances from the first limiting block and the second limiting block to the detection axle wire, separately. The quick positioning device can transfer a detected sensor to the center of the detection mechanism at one time without repeatedly adjusting, positioning and centering manually, so that the quick positioning device is time- and labor-saving.

The invention discloses a mounting suspension piece, a fixing structure and an assembling method for a double-glass photovoltaic module. The mounting suspension piece comprises clamping blocks and secondary keels, wherein a bearing part which is used for being adhered to the double-glass photovoltaic module is arranged on the top of the corresponding clamping block; a hook part which extends along a direction parallel to the bottom of the corresponding clamping block is arranged at the bottom of the corresponding clamping block; an extension arm is arranged on each secondary keel; one end of the extension arm is arranged on the top of the corresponding secondary keel while the other end of the extension arm extends outwardly along a direction parallel to the top of the corresponding secondary keel; and a clamping part for allowing the corresponding extension arm to be inserted is formed between the hook part and the bottom of the corresponding clamping block. The mounting assembly is simple in structure, convenient to mount, and capable of forming a steady buckling relation by only moving the corresponding clamping blocks to be clamped and connected with the corresponding secondary keels; and after the double-glass photovoltaic module is mounted, the stress part of the double-glass photovoltaic module is at the bottom, and the stress part can be scattered at multiple positions at the bottom.

A shoe enabling a user to walk quickly comprises a sole. The shoe is characterized in that three idler wheels are sequentially installed on the longitudinal center line of the sole from a heelpiece to the two-third position of the front side of the sole, preferably, the idler wheels are arranged in the mode that the idler wheels are exposed out of the sole by several millimeters, and the one-third part of the front side of the sole is the front sole part. The three idler wheels are detachably installed in three pits of the sole. Detachable pit pads are further arranged in the pits, the shape and the thickness of the pit pads are matched with the shape and the thickness of the pits so that after the idler wheels are taken out from the sole through a tool, the pit pads can right fill the pits to form the flat sole. The shoe enabling the user to walk quickly has the advantages that the shoe enables the user to walk normally and also enable the user to slide quickly, no mechanical conversion is needed for realizing the sliding state and the walking state, switching is convenient, braking is easy, the stability is good and operation is simple.
