The invention discloses a toppling-prevention drawer chest which comprises a chest body, drawers and supporting foot driving assemblies. The supporting foot driving assemblies are used for driving supporting feet to act. Any layer of drawers is provided with a connecting rod limiting device and an elastic convex block, and when the drawers are opened, the connecting rod limiting device on the layer of drawers can drive the supporting feet to extend out of the chest body; when the drawers are closed, and the finally closed drawers control retraction of the supporting feet through the elastic convex blocks. The toppling-prevention drawer chest achieves that any layer of drawers can control out-drawing of the supporting feet, the out-drawing distances of the supporting feet are controlled bythe drawers having maximum out-drawing distances; when the drawers are closed, the finally closed drawers flexibly control the supporting feet to retract through the elastic convex blocks.

The invention provides a sliding type anti-toppling forepoling hydraulic support and an action method thereof, and relates to the technical field of mine equipment. The sliding type anti-toppling forepoling hydraulic support comprises a base, a stand column, a top beam, a sliding rod, a bottom sliding plate, a pushing jack, a swing base, a lifting jack and a supporting disc. Through cooperation of the lifting jack, the pushing jack and the like, self-movement can be achieved, so that the carrying flexibility of the support is improved; in the supporting process, the swing base, the lifting jack and the supporting disc are swung to the left side position and the right side position of the base and are kept consistent with the width direction of the rectangular base, a telescopic rod of the lifting jack extends to enable the supporting disc to make contact with a roadway bottom plate, and therefore the base is supported in the width direction of the rectangular base; the supporting span of the base in the width direction is increased, when a top beam of the support is separated from a roadway top plate, even if a roadway bottom plate is uneven, the hydraulic support cannot topple over, and the supporting stability of the hydraulic support is improved.

The invention relates to a deplating device for preparing copper-plated pipes for air-conditioning compressors. The deplating pool is connected to the deplating chemical solution circulation system, and the deplating chemical solution will be between the deplating pool and the deplating chemical solution circulation system during the deplating process. To achieve circular supply and recovery, the base is height-adjustable and installed in the deplating pool. Multiple semi-finished tubes are placed vertically on the base, and the section that needs to be deplated faces downward; each semi-finished tube needs to be deplated for a section. The deplating height is α1; the deplating chemical liquid level height in the deplating pool is α2; the distance between the plane contacting the base and the semi-finished pipe body and the bottom surface of the deplating pool is α3; α1=α2 α3; the present invention also The invention includes a method for deplating copper-plated pipes for air-conditioning compressors by using a deplating device, including chemical deplating, and partially deplating semi-finished pipe bodies. The invention adopts chip-free processing to complete partial deplating, does not produce iron filings and burrs, reduces processing steps, effectively reduces production costs, and prolongs service life.

The invention belongs to the technical field of breathing valves, and in particular relates to a leak-proof breathing valve, which includes a breathing valve body. The breathing valve designed in the present invention can be used only when the oil tank is tilted to more than 20 degrees. The structure composed of the installation base will fall down, driving the frame body and the sealing plate to swing, so that the second air hole opened on the sealing plate and the first air hole opened on the sealing cover are misaligned one by one, so that the installation sleeve and the breathing valve The channel between the bodies is closed to prevent leakage; when the inclination angle of the oil tank is less than 20 degrees, because the installation base is larger than the projected area of ​​the counterweight and the installation rod on the installation base, the counterweight and installation rod The structure formed with the mounting base will not fall over. The breather valve designed by the present invention, when the anti-leakage mechanism is not needed, press the rack, and then the gear is locked through the locking bolt, the second lock hole opened on the rack and the first lock hole opened on the guide sleeve. The strip is fixed on the mounting shell.

The invention relates to an auxiliary device, in particular to an in-place auxiliary device for a switch cabinet, and belongs to the technical field of electric power construction. The in-place auxiliary device comprises two rails arranged in bilateral symmetry, the front ends of the two rails are connected through a front separating rod, front nut clamping openings are formed in the positions, connected with the front separating rod, of the two rails, front separating nuts are clamped in the front nut clamping openings, and the front separating nuts are connected with the front separating rod through threads. The rear ends of the two rails are connected through a rear separating rod, rear nut clamping openings are formed in the positions, connected with the rear separating rod, of the two rails, rear separating nuts are clamped in the rear nut clamping openings, and the rear separating nuts are connected with the rear separating rod through threads. According to the in-place auxiliary device, work staff can save more labor in the switch cabinet in-place process, a cabinet body moves stably and cannot topple over, the number of persons in the switch cabinet in-place matching process is greatly reduced, the in-place efficiency of the switch cabinet can be improved in multiples, and the cabinet body in-place time is shortened.

The invention discloses a multifunctional indoor decoration partition wall, and relates to the technical field of indoor decoration. The multifunctional indoor decoration partition wall is characterized by comprising a plurality of decoration units connected together, wherein each decoration unit comprises a rectangular outer frame and a box body slidably connected with the inner wall of the rectangular outer frame; the box bodies slide in the rectangular outer frames in the horizontal direction; each rectangular outer frame is defined by a top plate, a bottom plate, a left side plate and a right side plate; an opening is formed in the top of each box body; a horizontally-arranged containing plate is detachably connected to each opening; and a limiting assembly for limiting the sliding distance of each box body is arranged between the corresponding bottom plate and the bottom wall of the corresponding box body. According to the multifunctional indoor decoration partition wall, the partition effect can be achieved, and some articles can be stored through the box bodies; after the containing plates are covered, decorations such as potted plants or ornaments can be placed on the containing plates, and the decoration effect is achieved; and the box bodies can also serve as a bookshelf, the shape of the decoration partition wall can be changed through the position change of the multiple box bodies, and the diversified requirements of people are met.
