Description

Technical Field

[0001] The utility model relates to the technical field of chassis shells, in particular to a chassis sheet metal shell. Background Art

[0002] The chassis sheet metal shell is a product made of metal thin plates (generally below 6mm) using a comprehensive cold processing process. This process includes shearing, stamping, cutting, compounding, folding, welding, riveting, splicing and forming, and finally forms a box structure with metal properties. The chassis sheet metal shell is usually made of thin-walled steel materials, such as stainless steel plates or galvanized steel plates. After cold rolling and welding, it can withstand a certain amount of pressure. This shell is widely used in computers and other equipment. Due to its complex and diverse shapes and the particularity of its internal structure, its performance requirements are high. According to different uses and occasions, the chassis sheet metal shell can be divided into different categories to meet specific needs.

[0003] The patent with patent number CN219978801U discloses a chassis shell, including a shell, which is configured as a frame structure with an opening on one side, and L-shaped clips are symmetrically connected on the side of the shell and on both sides of the opening, and a cover plate is slidably connected between the two L-shaped clips, and the cover plate covers the opening on one side of the shell, and fixing holes are provided at both ends of the side of the L-shaped clip, and the four corners of the side of the cover plate are symmetrically connected with spring pin assemblies, and the cover plate is fixedly connected between the two L-shaped clips by inserting the spring pin assemblies into the fixing holes. The utility model can quickly install and remove the cover plate through the cooperation of the spring pin assemblies at the four corners of the cover plate and the fixing holes at both ends of the two L-shaped clips, thereby improving the convenience of disassembly and removal of the cover plate, and through the anti-seismic support foot assembly, the bottom of the shell plays a supporting and anti-seismic effect, thereby ensuring the reliability of the overall equipment.

[0004] The above device has certain shortcomings when used: when removing the cover, the elastic pin assembly is squeezed toward the inside of the L-shaped card strip, and the cover is pulled upward, so that the elastic pin assembly can be disengaged from the fixing hole, so that the cover can be quickly removed. Since the elastic pin assembly is located at the four corners of the cover, it is necessary to squeeze it at the same time to pull the cover out to complete the removal. This disassembly work of squeezing four positions at the same time may not be completed by one person, and requires two or more people to cooperate with each other to complete it. It consumes manpower during disassembly and assembly, increases labor costs and is not convenient to operate.

[0005] Therefore, the utility model provides a chassis sheet metal shell to solve the above problems. Utility Model Content

A groove is provided on the right side of the front wall of the cover, and an installation groove is provided on the top wall of the cover. A rotating seat is rotatably installed on the inner wall of the installation groove. The top wall of the chassis shell is provided with a placement groove, and a magnet is fixedly installed on the inner wall of the placement groove.

After installation, the structure is also very stable.

[0010] Furthermore, a fixing plate is fixedly installed on the side of the two L-shaped frames away from each other, and the fixing plates are screwed on the side walls of the chassis shell by bolts. The outer wall of the limiting protrusion 1 fits with the inner wall of the limiting groove on the left, and the outer wall of the limiting protrusion 2 fits with the inner wall of the limiting groove on the right.

[0011] Through the above technical solution, the two L-shaped frames are installed on the side wall of the chassis shell through the fixing plate, and the limiting protrusion 1 and the limiting protrusion 2 cooperate with each other to limit and fix the limiting groove.

[0012] Furthermore, an indicator arrow is installed on the front wall of the cover plate, the rotating seat is made of metal, the outer wall of the rotating seat is in contact with the inner wall of the placement groove, and the rotating seat and the magnet are attracted to each other.

[0016] Furthermore, a U-shaped elastic part is installed on the bottom wall of the chassis shell and the side wall of the U-shaped seat, and a limiting groove is provided on the inner wall of the U-shaped elastic part. A semicircular clamping block matching with it is fixedly installed on the front and rear walls of the rotating block and at the position corresponding to the limiting groove.

[0017] Through the above technical solution, when the semicircular clamping block enters and separates from the inner wall of the limiting groove in the U-shaped elastic member, it will drive the U-shaped elastic member to open.

[0018] Furthermore, elastic plates are fixedly installed on the front and rear parts of the bottom wall of the U-shaped seat, and two limiting grooves are provided on adjacent sides of the elastic plates.

[0019] Through the above technical solution, when the semicircular clamping block enters and separates from the two inner walls of the limiting groove in the elastic plate, it will drive the elastic plate to open.

[0024] (1) The chassis sheet metal shell drives the connecting plate, spring and limiting protrusion 1 into the L-shaped frame and the inner wall of the limiting groove on the left through the cover plate. The limiting protrusion 1 enters the limiting groove and drives it to move to the left through the groove to drive the connecting plate to squeeze the spring, push the cover plate inward to drive the limiting protrusion 2 into the inside of the L-shaped frame on the right, loosen the groove spring to push the connecting plate and the cover plate to move to the right, and the limiting protrusion 2 enters the corresponding inner wall of the limiting groove to be fixed. The rotating seat rotates in the inner wall of the installation groove and drives it to enter the inner wall of the placement groove to be adsorbed by the magnet to complete the fixing of the cover plate. When the cover plate is removed, The rotating seat rotates in the inner wall of the installation groove, driving it to disengage from the inner wall of the placement groove and separate from the magnet, and the cover plate drives the connecting plate to squeeze the spring, and the second limiting protrusion disengages from the corresponding inner wall of the limiting groove, and the left part of the cover plate enters the inner wall of the L-shaped frame on the left. The right part of the cover plate is moved outward to disengage from the inner wall of the L-shaped frame on the right. When the limiting protrusion disengages from the contact with the inner wall of the limiting groove, the cover plate can be moved to take it out, so that the installation and fixation of the cover plate can be completed quickly by one person. The overall installation method is simple and time-saving, and the structure is stable after the installation is completed. It does not require too much personnel participation, thereby reducing labor costs.

[0025] (2) The sheet metal shell of the chassis drives the universal wheel to move in the inner wall of the U-shaped seat by rotating the rotating block downward, so that the semicircular clamping block is separated from the contact with the inner wall of the limiting groove one, and the semicircular clamping block will drive the U-shaped elastic member to expand. When the rotating block rotates 90 degrees, it drives the semicircular clamping block to enter the inner wall of the limiting groove two and clamp and fix it. It enters the inner wall of the elastic plate and drives the elastic plate to expand to facilitate the entry of the semicircular clamping block, so that the universal wheel contacts the ground and supports the entire device. By rotating the handle and then pulling the chassis shell, the universal wheel moves around, making it easy to move the entire chassis to the working position without the need for back and forth transportation. It is more labor-saving when moving, and can be quickly folded up when it is not needed. BRIEF DESCRIPTION OF THE DRAWINGS
