JP2015173185A - Housing structure having screw fastening mechanism for stacking - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a stacking structure, having a fixation structure which prevents the displacement and the drop of a stacked housing, and enabling the stacking work of housings only with simple operation, when constructing a stack of the housings of the same structure.SOLUTION: A structure for stacking housings includes: a plurality of salients, formed on predetermined positions on the bottom surface of one housing, for lifting the one housing by a predetermined length from a construction plane; a plurality of recesses formed on each salient which faces each salient on the top surface of the one housing; screw insertion holes to which predetermined screws, formed at positions protruding from the top surface of the housing, are inserted from the side faces; and screw receivers, which are formed at positions to face the screw attachment holes of another housing of another device, for receiving and fastening screws when the one housing is laid on the other device having the other housing of the same shape as the one housing, so that the stacking work of housings can be made with simple operation.

Description

  The present invention relates to a housing, particularly a housing suitable for stacking installation.

  As a structure in which the casings are stacked and installed in the conventional technology, the fitting claws provided on the bottom surface of the housing and the ribs having the arrowhead-shaped protrusions are fixed by fitting the fitting grooves provided on the top face of the casing. There is a structure that prevents the housing from being displaced or dropped (for example, Patent Document 1).

  However, in Patent Document 1, an assembly operation for fitting the fitting claw and the rib having the arrowhead-shaped protrusion on the bottom surface of the housing with the fitting groove on the top surface of the housing is necessary when performing the stacking operation. It is. For this reason, the stacking work becomes complicated, the assembly and disassembly methods are difficult to understand, and the fitting claws are damaged.

JP 2001-189571 A

  In order to solve the above problems, the present invention can perform the stacking operation of the casings with simple operations when the casings are stacked, and the stacked casings can be displaced or dropped. It is an object of the present invention to provide a stacked structure having a fixed structure for preventing the above.

  In order to solve the above-described problems, the present invention provides a housing that constitutes the device capable of stacking a plurality of the devices in a substantially vertical direction on a substantially horizontal installation surface on which the predetermined device is installed. A plurality of convex portions that floats a predetermined length from the installation surface of the own housing formed at a predetermined portion of the bottom surface that constitutes the own housing, and the installation surface that is formed on the convex portion. A rubber foot receiving portion that detachably receives rubber feet, a plurality of concave portions formed in each portion facing the convex portion of the top surface constituting the housing, and a position protruding from the top surface of the housing A screw insertion hole for inserting a predetermined screw formed on the side surface of the case, and the case where the case is stacked on another device including a case having the same shape as the case. A screw that accepts and fastens the screw formed at a portion facing the screw mounting hole. Characterized in that it consists of a part.

  According to the present invention, when installing the casings in a stacked manner, the casings can be stacked by simple operations, and the fixing structure prevents the stacked casings from being displaced or dropped. A stacked structure can be provided.

The perspective view which shows the stacking state by one Embodiment of this invention (A) AA sectional view of FIG. 1 (b) Detailed view of the device engaging portion and the screw fastening portion in FIG.

  An embodiment of the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view showing a state in which the same casings are stacked according to an embodiment of the present invention. Reference numeral 1 denotes a lower casing, and reference numeral 2 denotes an upper casing.

  FIG. 2A shows a cross-sectional view taken along the line AA in FIG. In FIG. 2A, a rubber foot 10 is attached to the lower casing 1 and is used as a leg of the casing.

  FIG. 2B shows details of the device engaging portion and the screw fastening portion in FIG. In FIG. 2B, reference numeral 11 denotes a convex portion on the bottom surface of the case 2 of the upper case 2. The convex portion 11 on the bottom surface of the housing is formed with a rubber foot receiving hole 22 that holds the housing and receives the rubber foot 10 used as a leg of the housing. In the present embodiment, the number of convex portions is expressed as four, but it may be one or more and is not limited thereto.

  Reference numeral 21 denotes a recess on the top surface of the lower casing 1. The concave portion 21 on the top surface of the housing is provided at a position facing the convex portion 11 on the bottom surface of the housing of the upper housing 2. The shape of the concave portion 21 on the top surface of the housing is formed to have a diameter larger than the outer shape of the convex portion 11 on the bottom surface of the housing and deeper than the height of the convex portion 11. As a result, the concave portion 21 on the top surface of the housing and the convex portion 11 on the bottom surface of the housing are engaged.

  In addition, by making the diameter of the concave portion 21 on the top surface of the casing closer to the diameter of the convex portion 11 on the bottom surface of the casing, the convex portion 11 on the bottom surface of the casing of the upper casing 2 and the top surface of the casing of the lower casing 1. Since the positional accuracy with respect to the concave portion 21 becomes higher, it is possible to more easily fix the stacked product.

  As described above, the stacking operator can perform the stacking fixing operation only by a simple operation of engaging the convex portion on the bottom surface of the housing with the concave portion on the top surface of the housing and fastening the screw from the side surface.

  In this figure, as an example, a two-stage stack has been described. However, if the number of screws is increased, any number of stages can be installed.
