The invention relates to a car of a temporary freight elevator of a high-rise building. The car comprises a car body, two sliding slots, a supporting and rotating device, a positioning device, a positioning block and an interlayer unit. The two sliding slots are formed in the upper and lower ends of the car body, the supporting and rotating device is arranged between the two sliding slots, the positioning device is arranged in the sliding slot in the lower side of the car body, the positioning block is mounted in the middle of the left end of the car body, and the interlayer unit is arranged at the back end of the car body. The car can solve the problems that when cargoes are stacked, it is often needed to place small parts and relatively light cargoes above, staff needs to select the placing positions of the cargoes by way of observation or weighing, the cargoes in the relatively high positions may collapse, and when the stacked cargoes need to be unloaded from different floors, it isneeded to take out front cargoes when the rear cargoes in the car are taken out, and then the front cargoes are placed again after the rear cargoes are taken out.

The invention belongs to the technical field of manufacturing of light-emitting tubes, and particularly relates to a self-luminous tube and a manufacturing method thereof. The self-luminous tube in the manufacturing method comprises a top plate, a bottom plate, a reflector column and a lamp tube. One end of the lamp tube is mounted on the top plate, and the other end is mounted on the bottom plate. The side wall of the bottom end of the top plate and the side wall of the top end of the bottom plate are each provided with an annular inner sliding groove and an annular outer sliding groove. Thenumber of the reflector columns is multiple. Sliding columns are symmetrically arranged at the two ends of the reflector columns, and the reflector columns are slidably connected into the annular inner sliding groove and the annular outer sliding groove through the sliding columns correspondingly. The top plate, the bottom plate, the reflective mirror column and the lamp tube are matched to reflect light to the self-luminous tube, so that the distance of light emitted by the self-luminous tube is prolonged, and the outdoor using effect and the outdoor using range of the self-luminous lamp tubeare enhanced.

The invention discloses a using method of a wooden wine box. The using method comprises the following steps that a, a box cover is opened from a box body, a bottle opening of a wine bottle is enabledto penetrate through a round hole (31) in an inclined state and penetrates into a bottle opening fixing device he wine bottle, and the wine bottle is continuously moved upwards until the wine bottle is completely placed in the box body; b, after the lower part of the wine bottle is adjusted to be right opposite to a bottle bottom fixing device, the lower part of the wine bottle is moved downwards,and the lower part of the wine bottle is placed in the bottle bottom fixing device; and c, a lifting handle is pulled upwards to enable the lifting handle to be changed from a first position to a second position, and a reinforcing device is driven to perform reinforcing operation on the wine bottle. According to the using method of the wooden wine box, the lifting handle is pulled out of the position of the box body, the reinforcing device can be used for performing reinforcing and damping operation on the wine bottle at the same time, so that the possibility of wine bottle crushing is reduced, and the quality of wine is improved after shake of the wine bottle is reduced; and the reinforcing device can automatically perform the reinforcing operation when the lifting handle is pulled out,the wine bottle is automatically reinforced, the operation is simple and convenient, and the reinforcing effect is stable.

The invention relates to a side baffle for submerged arc welding of shaft parts, which comprises a side baffle body, a layer of asbestos is attached to the front surface of the side baffle body, and several magnetic columns are evenly fixed on the lower side of the front end surface of the side baffle body. An end block is respectively fixed on the left and right sides of the lower end surface of the side baffle body, a compression spring is respectively fixed on the inner side of the end block, and a holding plate is respectively fixed on the other end of the compression spring. The holding boards are all installed on the lower end surface of the side baffle body through a sliding connection, and the inner surfaces of the holding boards are all concave arc surfaces. In the present invention, the holding plate is used to be stuck on the surface of the shaft part, specifically, it can be stuck at the annular groove of the shaft part, so that the side baffle body is blocked on the side of the working surface of the shaft part, and the fixing of the side baffle body is improved. Stability, combined with the adsorption effect of the magnetic column on the shaft parts, further ensures the fixing reliability of the side baffle body.
