Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a portable housing fixing structure in which, for example, measuring devices forming a housing are integrally combined.

[0002]

[Prior Art]

 In general, various characteristics are often measured with a measuring instrument mainly in a fixed place such as indoors. Sometimes it is carried and measured. In addition, when performing measurements, it is often the case that it is used in combination with other measuring instruments due to the poor mobility of a single measuring instrument alone. The case combined in this way may be used with the legs tilted, and various forms are adopted depending on the measurement environment. Therefore, as shown in FIGS. The body had a fixed structure that could be freely carried and fixed.

That is, a rectangular cutout hole 33 is formed in the front of the stacked casings, that is, the legs 32 provided at the four corners of the bottom plate 31 a of the upper casing 31. Further, among the leg portions 32 at the four corners, long grooves 34 are formed in the height direction of the leg portions 32A on the back surface of the rear leg portions 32A.

On the other hand, the casings to be stacked, that is, the upper plate 35a of the lower casing 35, is provided with a claw piece that is bent into a J shape and is fitted into the cutout hole 33 of each leg portion 32. A stopper 36 having 36a is fixed. Further, the lower housing 35 is provided with a pressing member 37 whose both ends are symmetrically bent at right angles. One end surface 37a of the bent portion of the pressing member 37 is fixed to the upper portion of the back plate 35b of the housing 35 by inserting a screw 39 into a horizontally long groove 38, and the other end surface 37b of the bent portion is attached to the other end surface 37b. A protrusion 40 is formed to be engaged with the long groove 34 of the leg portion 32.

When fixing the casings 31 and 35, first, the upper casing 31 that is stacked is placed on the lower casing 35 so that the stopper 36 fits into the cutout hole 33 of the leg portion 32. Is inserted from the back plate 35b side. Next, with the claw pieces 36a of the stoppers 36 fitted in the corresponding notch holes 33, the protrusions 40 of the retainer member 37 are locked in the long grooves 34 of the rear leg portion 32A so that the retainer member 37 is retained. The position is adjusted by moving itself along the groove 38. Then, while the protrusion 40 is locked in the long groove 34, the screw 39 is tightened and fixed so that the tip end surface of the pressing member 37 presses the rear surface of the rear leg portion 32A. As a result, the stopper 36 is prevented from coming off from the notch hole 33 in the direction opposite to the mounting direction, and the upper and lower casings 31, 35 are fixed.

[0006]

[Problems to be solved by the device]

 However, in the above-described conventional casing fixing structure, when fixing the casings 31 and 35, the stoppers that are locked to the leg portions 32 of the casing 31 and the cutout holes 33 of the leg portions 32 are used. Since the positional relationship with 36 can not be accurately grasped from the outside, when the stopper 36 is aligned with the notch hole 33, in addition to relying on groping or intuition, the gap between the casings 31 and 35 causes the leg portion I looked into 32 and checked the position of stopper 36 and each other. In addition to this, two sets of pressing members 37 by tightening screws 39 were used for final fixing between the housings 31 and 35, so that the number of parts increases and the space between the housings 31 and 35 increases. There was a problem that the work efficiency was poor because the attachment and detachment was troublesome.

Therefore, the present invention has been made in view of the above problems, and an object thereof is to easily perform positioning when fixing the casings and to improve workability in attaching and detaching the casings. It is an object of the present invention to provide a housing fixing structure that is improved and that can be shared by using some of the components that have been conventionally used.

[0008]

[Means for Solving the Problems]

 To achieve the above object, the structure for fixing a housing according to the present invention comprises a leg portion 2 having a cutout hole 3 disposed on a bottom surface 1a of the housing 1 and the cutout in a state where the housings are stacked. A stopper 6 that fits into the hole, a guide 7 that guides the legs of the upper casing 1B to the stoppers of the lower casing 1A, and a casing that is disposed between the casings and is operated by one-touch operation. It is characterized in that it is provided with a lock mechanism 9 for fixing and releasing between the casings in the mounting direction of the body.

[0009]

[Action]

 Each leg 2 of the upper casing 1B is guided by the guide 7 to each stopper 6 of the corresponding lower casing 1A, and the cutout holes 3 of each leg 2 fit into the corresponding stoppers 6. It From this state, the one-touch operation of the lock mechanism 9 fixes the housings 1 (1A, 1B) in the mounting direction of the housing 1B.

 FIG. 1 is an exploded perspective view showing an embodiment of a housing fixing structure according to the present invention, and FIG. 2 is a side view showing a state where the housings are fixed by the fixed structure.

The rectangular parallelepiped leg portions 2 are fixed to the four corners of the bottom plate 1a of the housing 1B. A rectangular cutout 3 is formed in each leg 2 in the depth direction. Further, an engaging plate 4 bent in an L shape is fixedly provided substantially at the center of the bottom plate 1a, and one end of the engaging plate 4 vertically extending from the bottom plate 1a has a rectangular shape. The mounting hole 5 is formed.

On the other hand, in the stacked housings, that is, in the upper surface plate 1b of the lower housing 1A, the stacked housings, that is, the positions corresponding to the legs 2 of the upper housing 1B, are located at the housing 1B. A J-shaped stopper 6 having an opening on the side opposite to the mounting direction (in the embodiment, the front plate 1c side of the housing) is fixed. The stopper 6 forms a mounting piece 6a whose long plate portion forms a mounting surface with the housing 1A. Also, the part that is folded back 90 degrees above the rear part of the mounting piece 6a and that is folded back 90 degrees on the side opposite to the mounting direction at the height H corresponding to the cutout hole 3 of each leg 2 is the claw piece. 6b is formed. The claw pieces 6b are fitted in the cutout holes 3 of the corresponding leg portions 2 of the upper casing 1B in a state where the casings 1A and 1B are stacked.

In addition, the two stoppers 6A arranged side by side in the depth direction of the housing 1A are integrally provided with a guide piece 7 that is inclined so as to spread toward the side plate 1d of the housing 1A with respect to the mounting piece 6a. Has been formed. When the upper casing 1B is placed on the lower casing 1A from slightly above the front plate 1c side, the guide pieces 7 correspond to the legs 2A of the upper casing 1B corresponding to the inner side surface 7a. The leg portions 2 are guided onto the attachment pieces 6a by abutting on the outer ridge lines 2a. Further, when the upper casing 1B is inserted in the depth direction of the lower casing 1A, the inner side surface 7a abuts on the outer ridge lines 2a of the corresponding leg portions 2A of the upper casing 1B so as to cut the respective casings. The notch 3 is guided to the corresponding claw piece 6b of each stopper 6.

Further, on the upper surface plate 1b of the lower housing 1A, at a position corresponding to the engagement plate 4 of the upper housing 1B, a fixing member for preventing the upper housing 1B from coming off in the opposite mounting direction. 8 is fixed, and the engaging plate 4 constitutes a lock mechanism 9. More specifically, the fixing member 8 is provided with the operation protrusion 11 protruding from the outer surface 10a of the case body 10. An engagement block 12 that engages with the mounting hole 5 of the engagement plate 4 of the upper housing 1B is provided on one side surface 10b of the case body 10. The engagement block 12 projects from the side surface 10b of the case body 10 when the operation protrusion 11 is not operated, and is configured to be retracted into the case body 10 by pushing the operation protrusion 11.

Next, in the case where the casings are fixed by the casing fixing structure configured as described above, first, the centers of the casings 1A and 1B in the depth direction are substantially aligned with each other, or the upper side With the center of the housing 1B in the depth direction slightly displaced from the center of the lower housing 1A in the depth direction toward the side with the guide piece 7, the housing 1A is fixed with respect to the housing 1A on the fixed side. 1B is placed slightly closer to the front plate 1c side. At this time, the leg portions 2A of the upper casing 1B arranged side by side in the depth direction are guided to the mounting piece 6a with their outer ridge lines 2a abutting the inner side surface 7a of the corresponding guide piece 7.

In this state, the upper casing 1B is inserted in the depth direction of the lower casing 1A. At this time, the outer ridge lines 2a of the legs 2A of the upper casing 1B juxtaposed in the depth direction abut against the inner side surface 7a of the guide plate 7 so that the cutout holes 3 of the legs 2 form the stoppers 6. Is guided to the nail piece 6b.

Next, the operation protrusion 11 of the fixing member 8 provided on the lower casing 1A is pushed by hand to retract the engagement block 12 into the case body 10 and at the same time the casing 1B is further deepened. Insert in the direction. As a result, in a state where the upper and lower casings 1A and 1B are overlapped with each other when seen in a plan view, the cutout holes 3 of the leg portions 2 of the upper casing 1B correspond to the stoppers 6 of the corresponding lower casing 1A. It is locked to the claw portion 6b. As a result, the upper housing 1B is fixed to the lower housing 1A to some extent in the depth direction, the lateral direction, and the vertical direction.

Further, when the engagement block 12 is aligned with the mounting hole 5 of the engagement plate 4, the hand is released from the operation protrusion 11 to release the pressure on the operation protrusion 11. As a result, the engaging block 12 is engaged with the mounting hole 5, and the upper and lower casings 1A and 1B are fixed to each other in the upper and lower directions and the rotating direction in the overlapping state.

Further, when the fixation between the housings 1 A and 1 B is released, the operation block 11 of the fixing member 8 is manually pushed to retract the engagement block 12 into the case body 10, and the engagement block 12 Is released from the mounting hole 5 of the engaging plate 4. In this state, the upper housing 1B is pulled out to the front plate 1c side of the housing 1A.

Therefore, in the above-described embodiment, when fixing the casings 1A and 1B, the action of the guide piece 7 formed integrally with the stopper 6 causes the leg portion and stopper to be separated from each other as in the conventional case. The leg portions 2 of the upper casing 1B can be aligned with the stoppers 6 of the lower casing 1A without visually checking the positional relationship between the components, whereby the claw pieces of the stoppers 6 can be aligned. The notch hole 3 of each leg 2 can be fitted into 6b very easily. Further, since the lock mechanism 9 by one-touch operation is used for final fixing between the casings 1A and 1B, workability in attaching and detaching the casings 1A and 1B can be improved as compared with the conventional case. Further, a part of the stopper 6 having the notch hole 3 formed in the leg portion 2 of the housing 1 and the claw piece 6b into which the notch hole 2 fits is made of a conventionally used component. Therefore, it is possible to use common parts without complicating the configuration. Further, the lock mechanism 9 can be arranged in an inconspicuous position on the rear surface side of the housing 1 by effectively utilizing the space S between the housings 1A and 1B, and the aesthetic appearance is not impaired.
