The special tyre comprises a tyre body, the tyre body is composed of a tyre surface, tyre shoulders and tyre sidewalls, the tyre shoulders and the tyre sidewalls are sequentially and symmetrically positioned at two sides of the tyre surface, the tyre shoulders are provided with a ring of a first multi-corner pattern block sequence and a ring of a fourth multi-angle pattern block sequence surrounding the tyre shoulders respectively, a ring of a second multi-corner pattern block sequence and a ring of a third multi-corner pattern block sequence are arranged surrounding the tyre surface in a spaced manner, the first, second, third and fourth multi-corner pattern block sequences respectively comprise a plurality of multi-corner pattern blocks arrayed in a spaced and regular manner and are sequentially arrayed in a spaced parallel manner, the first multi-corner pattern block sequence and the fourth multi-corner pattern block sequence are same and are opposite in distribution direction, and the second multi-corner pattern block sequence and the third multi-corner pattern block sequence are same and are opposite in distribution direction. The special tyre can well cope with poor off-road road conditions, and performances a strong driving force especially when general vehicles are impassable in a disaster and on a collapsed road.

The invention discloses an energy-saving and heat-preservation wall for a building. The wall comprises a load bearing wall body, a waterproof plate is fixedly connected to the right side of the load bearing wall body, a sponge heat-preservation plate is fixedly connected to the right side of the waterproof plate, a fireproof plate is fixedly connected to the right side of the sponge heat-preservation plate, and an energy-saving and heat-preservation plate is fixedly connected to the right side of the fireproof plate; embedded rods are symmetrically arranged in the load bearing wall body, the right end of each embedded rod sequentially penetrates through the load bearing wall body, the waterproof plate, the sponge heat-preservation plate, the fireproof plate and the energy-saving and heat-preservation plate from left to right and extends to the outside of the energy-saving and heat-preservation plate, and the portion, located outside the energy-saving and heat-preservation plate, of thesurface of each embedded rod is in threaded connection with a fastening buckle. The wall is simple in structure, low in cost and good in impact resistance; it is ensured that after the wall is subjected to large impact force, the heat-preservation plates cannot be broken or shed; moreover, it is ensured that the body of people who the impact force is applied to cannot be injured, and the household or office use needs can be completely met.

The invention discloses a reed transfer vehicle for a textile factory, which comprises a frame body and a reed body, and also includes a buffer mechanism arranged at the inner four corners of the top of the frame body. The buffer mechanism includes a support plate for supporting the steel reed body, The connecting rod assembly and the rotating part for fixing the reed body, the connecting rod assembly is driven by the support plate to insert the plug part on the outer wall of the rotating part into the reed tooth gap of the steel reed body, so that the reed body and the frame are connected The body remains fixed. The reed transfer vehicle provided by the invention can reduce the impact of the reed body caused by the vibration of the frame body during the transportation process, can limit the sliding of the reed body in the horizontal direction, and can limit the reed body in the horizontal direction. Sliding reduces the damage caused by the collision between the reed body and the frame body, realizes that when it needs to be moved, it can be lifted and moved, and when it needs to be fixed, it can be fixed by placing it, which can facilitate the operator to move and fix the frame body.

The invention discloses a day-and-night universal eye opening-and-closing type patch for a start viewing instrument. The day-and-night universal eye opening-and-closing type patch comprises a main connecting component; the left end of the outer wall of the main connecting component is provided with an elastic rubber ring in a clamping manner; the left end of the elastic rubber ring is provided with an auxiliary connecting component in a clamping manner; the outer wall of the auxiliary connecting component is sleeved with a pressing ring; the auxiliary connecting component is fixed to the elastic rubber ring in a pressed manner through the pressing ring; the right end of the outer wall of the main connecting component is provided with a limiting slide groove; the limiting slide groove is sleeved with a limiting ring; the inner wall and the outer wall of the limiting ring are symmetrically provided with a plurality of protruding blocks; fixing holes are formed at the central portions of the protruding blocks; the outer wall of the limiting ring is provided with a patch in a clamping manner; the outer wall of the patch is sleeved with a fixing pressing ring; screw holes are formed in the wall of the fixing pressing ring; and the patch is fixedly connected with the limiting ring through screws in the screw holes in the wall of the fixing pressing ring, wherein the limiting ring sleeves the limiting slide groove. The day-and-night universal eye opening-and-closing type patch for the start viewing instrument has the advantages of high practicability and convenience in opening and closing, and can be normally opened.

The invention relates to the technical field of display screens, and discloses a high-definition LED display screen with a protective function, which includes a top seat, an upper notch is provided on the upper surface of the top seat, and a wind energy power mechanism is arranged inside the upper notch. The power mechanism includes a left cylinder and a right cylinder. The end of the left cylinder away from the side wall of the upper notch is fixedly connected with a threaded column. The outside of the threaded column is provided with a gear ring plate, and the two sides below the gear ring plate are respectively provided with a protective mechanism and The heat dissipation mechanism is equipped with a wind energy power mechanism and a protective mechanism. When encountering strong winds, the protective curtain in the protective mechanism opens and falls to close with the bottom groove, thereby closing the front side of the display body, and cooperates with the right plate and the bottom groove. The left plate seals both sides of the display body, and at this time, the display body can be directly protected by the protective curtain when the display body is affected by strong winds, so as to avoid the damage of the display screen from external influences and effectively protect the display screen. The screen is protected.
