The invention relates to a method for operating a transmission device (1), in particular a double-clutch transmission device, the transmission device (1) comprising a plurality of gear selectors (2, 3, 4, 5) each having a gear selector valve (15, 16, 17, 18), and a gear selector piston (23, 24, 25, 26) which is operatively connected to a selector fork of the transmission device (1), is arranged in a gear selector cylinder (19, 20, 21, 22) and divides the latter into a first pressure chamber (27, 28, 29, 30) and a second pressure chamber (31, 32, 30 36). In a first shifting position of the gear selector valve (15, 16, 17, 18), the first pressure chamber (27, 28, 29, 30) has a flow connection to a common feed line (12), in a second shifting position, the second pressure chamber (31, 32, 33, 34) has a flow connection to a common feed line (12), and in a neutral position, none of the pressure chambers (27, 31; 28, 32; 29, 33; 30, 34) has a flow connection to a common feed line; and a flow connection of the feed line (12) to a common pressure source (6) is enabled in a first operating position of the shifting valve (13) and is interrupted in a second operating position of the shifting valve (13). Here, according to the invention, to achieve a change from a standby operating mode into a power saving operating mode, a pressure test is carried out, in which the gear selector valves (15, 16, 17, 18) of the gear selectors (2, 3, 4, 5) for setting the neutral position and the shifting valve (13) for setting the second operating position are activated, and then the gear selector valve (15, 16, 17, 18) of at least one of the gear selectors (2, 3, 4, 5) for setting one of the shifting positions is activated.

The invention discloses an electric wheel stopping device and a three-dimensional garage carrying hanging bracket using the same. The stopping device comprises a rack body having a rectangular cross section. The rack body is fixed in a square hole that is formed in the top surface of a carrying plate of a three-dimensional garage and has an upward opening. Longitudinal rails are arranged on the right side surface of the left side of the rack body and the bottom end of the left side surface of the right side respectively. A first square panel is hinged to the rear side surface of the front sideof the rack body; a second square panel is hinged to the rear end of the first square panel; and the left side and the right side of the rear end of the second square panel can slide on the longitudinal rails respectively. Electric telescopic devices are arranged at the left and the right end of the rack body symmetrically; a horizontal plate is connected to the front ends of telescopic shafts ofthe two electric telescopic devices; a longitudinal pull rod is connected to the middle portion of the horizontal plate; and the rear end of the longitudinal pull rod is hinged to the rear end of thesecond square panel. Therefore, movement of a vehicle is prevented and thus accident occurrence is avoided.

The invention discloses a roller and foundation bolt switching type box supporting structure. The structure comprises a box body foot portion bottom plate, wherein the bottom of the box body foot portion bottom plate is fixedly connected with a fixing block, and the middle of the fixing block is connected with a conversion block capable of rotating around a central shaft by 90 degrees through thecentral shaft; the conversion block comprises two side plates arranged on the two sides of the fixing block and two mounting plates connected with the two side plates, wherein the two mounting platesare mounted on two adjacent sides of the two side plates, a universal roller set is mounted on one of the mounting plates, a foundation bolt is mounted on the other mounting plate, and a conversion and positioning device is arranged between the fixing block and the conversion block. According to the structure, temporary movement and positioning of the box body are facilitated, the operation is simple and convenient, and the reliability is high.

The invention provides a buoyance device which aims at effectively preventing self-displacement on the water surface and effectively providing an aid-to-navigation function and an underwater floating body being comprised in the buoyance device. The underwater floating body comprises a floating body (1) and a counter weight body (2) which is arranged on the lower portion of the floating body (1); the floating body (1) is in a streamline shape; the buoyance device comprises the floating body and a lighthouse (6) which is fixedly arranged on the floating body (1). The underwater floating body and the buoyance device comprising same can be applied to the field of aid-to-navigation devices.

The invention discloses a table tennis ball trademark printing machine. The key point of the technical scheme of the table tennis ball trademark printing machine lies in that the machine comprises a machine body, a printing device disposed at the upper end of the machine body, a feeding device arranged at the lower end of the machine body and matched with the printing device, a control box mounted on the machine body and used for controlling the printing device and the feeding device, a storage box mounted on the machine body and matched with the feeding device, and a collecting box disposed on the machine body. By means of the table tennis ball trademark printing machine, trademarks can be automatically printed onto table tennis balls, moreover the table tennis balls can be automatically discharged and collected, the manpower cost is reduced, and the production efficiency is improved.
