[0020] Furthermore, since the container deformation receiving part 16 must be provided avoiding the position of the cover 15, it is necessary to have a mechanism for detecting the cover 15 and a mechanism for aligning the positions of the cover 15 and the container deformation receiving part 16, so that the structure becomes complicated.
Furthermore, because the shape of the container deformation receiving part 16 must be adjusted according to the model of the container 10, the manufacturing cost of the container deformation receiving part 16 becomes high.

[0039] Figure 1A is a plan view of a container applied to the leak inspection device of the first embodiment of the present invention. Figure 1B It is a longitudinal sectional view of the above-mentioned leakage inspection device.

[0040] The box body 1 includes an upper wall and a cylindrical side plate, and a flange 2 extending outward is formed on the lower end of the side plate. The case cover 3 overlaps with the flange 2 of the case 1 through a sealing member such as an O-ring, so that the flange 2 is detachably fixed. The housing 1 is provided with an exhaust port for evacuating the internal space thereof and an inlet port for introducing air (both are not shown). Furthermore, a connection port (not shown) for a pipe serving both as an exhaust port and an inlet port is provided in the case 1 . The container 10 is formed in a cylindrical shape composed of a bottom plate 11, side plates 12, and a top plate 13, and is used to enclose gas or liquid for storage or trans...

[0049] Second, refer to Figure 2A as well as Figure 2B A leak inspection device according to a second embodiment of the present invention will be described. In the second embodiment, the same symbols are used for the same structural components as those of the first embodiment and detailed description thereof is omitted. In the second embodiment, the top plate center pressing part 23 is provided under the center of the coupling part 21, which is different from the first embodiment. Such as Figure 2B As shown, the top plate central pressing member 23 is, for example, a bottomed cylindrical shape. The top plate edge pressing member 20 provided on the connecting member 21 is in contact with the edge of the top plate 13 of the container 10, and the top plate central pressing member 23 is attached to the connecting member 21 so as to be in contact with the handle 14 located at the center of the top plate 13. superior. That is, the height of the top panel central pressing mem...

[0052] Next, refer to Figure 3A as well as Figure 3B A leak inspection device according to a third embodiment of the present invention will be described. In the third embodiment, the same symbols are used for the same components as those in the first and second embodiments, and detailed description thereof will be omitted. The third embodiment differs from the second embodiment in that a top panel central pressing member 25 is provided via an elastic member 24 at the center of the coupling member 21 . The top plate central pressing member has a bottomed shape and is arranged at a position where it contacts the handle 14 at the center of the top plate 13 when the top plate edge pressing member 20 contacts the edge of the top plate 13 of the container 10 . Furthermore, when the top plate edge pressing member 20 is in contact with the edge of the top plate 13 , the elastic member 24 is a spring member that functions as a compression spring between the coupling member 21 and t...

Abstract

The present invention provides a leak inspection apparatus which is used for inspecting the defect of the inspected object that is inserted into a container in a box body, etc. The lead inspection apparatus comprises the following components: a supporting component which is kept by a box body; and a top plate edge part pressing component which is supported by the supporting component, presses theedge part of the top plate of the container in the box body in the whole circumferential surface and is of a bottomless ring shape. Furthermore, the leak inspection apparatus can also comprises a topplate center pressing component which is supported by the supporting component and presses the central part of the top plate of the container in the box body. The supporting component comprises a supporting rod which inserts through an upper wall of the box body in a vertical direction and is supported by a mode that the vertical movement is allowed relatively to the upper wall, and a connecting component which is fixed to the lower end of the supporting rod. Furthermore the top plate edge part pressing component and / or the top plate center pressing component are supported through the connecting component. Thus when the top plate of the container is pressed, not only can the pressing mark prevented, but also the expansion and the deformation of the container can be prevented.

Description

technical field [0001] The invention relates to a leakage inspection device, which inserts an object to be inspected into a closed box and vacuumizes the container to detect air leaked from the object to be inspected into the box, such as the gas enclosed in the container, thereby inspecting the object to be inspected. No leak sites. [0002] This application claims priority based on Japanese Patent Application Japanese Patent Application No. 2008-289409 (filing date: November 12, 2008), and the content thereof is incorporated herein. Background technique [0003] Currently, various leak inspection devices have been developed and disclosed in the following documents. [0004] Patent Document 1: Japanese Patent No. 3348484 [0005] Patent Document 2: JP-A-2001-27574 [0006] Patent Document 1 discloses a leak detection device (leakage detector). A container-shaped object to be inspected is inserted into a sealed box, and the object to be inspected and the box are vacuum-ex...
