Technical Field
[0001] The utility model relates to the technical field of hinge structures, in particular to a base structure with a rotary hinge and a silent machine box body. Background Art
[0002] Silent machines include silent generators, silent welding machines, silent DC chargers, etc. For the convenience of overhauling internal machinery and equipment, in the prior art, the silent machine box body is designed to include a base and a flip-up upper cover. Equipment is installed inside the base, and the upper cover is connected to the base through an assembled hinge. One side of the assembled hinge is bolted to the base. Since the equipment inside the base generates vibrations during operation, it is easy to cause the bolts or nuts to loosen or even fall off, resulting in damage to the box body. Content of the Utility Model
[0003] The first object of the present utility model is: aiming at the problem in the prior art that the upper cover of the silent machine box body is connected to the base through an assembled hinge, vibrations are generated during the operation of the equipment, and the bolts or nuts at the connection between the hinge and the base are prone to loosen or even fall off, resulting in damage to the box body, to provide a base structure with a rotary hinge; the second object of the present utility model is to provide a silent machine box body.
[0004] In order to achieve the above first object, the technical solution adopted by the present utility model is:
[0005] A base structure with a rotary hinge includes a base, a rotary support member and a rotary member. The base includes a bottom plate and a frame connected above the bottom plate; the bottom and side parts of the rotary support member are respectively welded to the top surface of the bottom plate and the inner side surface of the frame; a rotating shaft parallel to the bottom plate is installed on the rotary support member, and one end of the rotary member is rotatably sleeved on the rotating shaft.
[0006] For the present utility model adopting the foregoing technical solution, by fixedly connecting the other end of the rotary member to the upper cover of the box body, the flipping of the upper cover can be realized; by designing the base to include a bottom plate and a frame connected above the bottom plate, and the rotary support member is simultaneously welded to the top surface of the bottom plate and the inner side surface of the frame, the rotary support member and the base are not only welded into an integral structure, but also the connection strength between the two is relatively high, and the impact resistance is better. The vibrations of the equipment will not cause the two to separate. Compared with the prior art in which the upper cover of the silent machine box body is connected to the base through an assembled hinge, vibrations are generated during the operation of the equipment, and the bolts or nuts at the connection between the hinge and the base are prone to loosen or even fall off, resulting in damage to the box body, the present utility model cancels the assembled hinge connection method, and the rotary support member and the base are welded into an integral structure, avoiding the phenomenon that the bolts or nuts are prone to loosen or even fall off due to the vibrations of the equipment during operation.
[0007] Further, it includes two of the rotary supports; the frame is a rectangular frame, and the two rotary supports are respectively arranged at two opposite corners on one side of the frame. The side parts of any one of the rotary supports are respectively welded to the two sides of the frame corner; the center lines of the rotating shafts of the two rotary supports coincide. By arranging the rotary support at the frame corner, a hidden effect can be formed for the rotary support, avoiding interference with the installation of equipment in the base, and the appearance is simple and beautiful.
[0008] Further, a cavity is formed inside any one of the rotary supports, the rotating shaft is installed in the cavity, and a vertical relief groove is also provided on the side surface of the rotary support; the relief groove communicates with the cavity to form an avoidance space for the rotation of the rotating part. In this way, the occupied space of the rotary support and the rotating part in the base can be reduced, and the installation space of the equipment in the base can be increased.
[0009] Further, any one of the rotary supports is a vertically arranged bent plate with an L-shaped cross-section, and its two ends are respectively welded to the two sides of the frame corner; the rotating part is an L-shaped strip plate. In this way, the structures of the rotary support and the rotating part are simple, and they can be made by laser cutting the plate, with relatively low production costs.
[0010] Further, a cross beam is provided on the top surface of the bottom plate, and the bottom of the rotary support is welded to the cross beam; the rotary support, the cross beam and the frame corner are welded together to form a stressed whole, which plays a very good supporting role for the stacking, transportation and operation of the equipment.
[0011] Further, an inward flanging is provided at the top of the frame, and the top of the rotary support is welded to the flanging; the rotary support, the cross beam, the flanging and the frame corner are welded together to form a stressed whole, which plays a very good supporting role for the stacking, transportation and operation of the equipment.
[0012] Further, the rotation angle of the rotating part around the rotating shaft is at least 90°; so that the upper cover has a sufficient flipping amplitude, which is convenient for overhauling the internal equipment.
[0013] Further, an installation hole is provided on the rotary support, a bushing is installed in the installation hole, one end of the rotating shaft is inserted into the bushing, and the other end of the rotating shaft is sleeved with the rotating part.
[0014] Further, a gasket is sleeved on the rotating shaft, and the gasket is located between the bushing and the rotating part; the gasket is provided to prevent abnormal noise generated by friction between the rotating part and the bushing when the rotating part rotates.
[0015] To achieve the second object, the present invention adopts the following technical solutions:
[0016] A silent machine box body includes the above-mentioned base structure with a rotary hinge.
[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: The assembled hinge connection method is cancelled, and the rotary support is integrally formed by welding with the base, avoiding the phenomenon that bolts or nuts are prone to loosen or even fall off due to the vibration during the operation of the equipment; The rotary support is arranged at the corner of the frame, which can form a hidden effect on the rotary support, avoiding interference with the installation of the equipment in the base, and the appearance is simple and beautiful; The structures of the rotary support and the rotary part are simple and can be made by laser cutting the sheet, with low production cost; The rotary support, the cross beam, the flanging and the corner of the frame are welded into an integral force-bearing body, which plays a very good supporting role in the stacking, transportation and operation of the equipment; The structure is simple, and the rotating shaft, the rotary part, the shaft sleeve and the rotary support are positioned with each other during assembly, and the consistency is good after assembly; The silent machine box body has the same technical effects as the above-mentioned base structure with a rotary hinge.
