The invention discloses a self-locking rail clamping device. The self-locking rail clamping device comprises a base, a pair of clamping pliers and a telescopic device, wherein the pair of clamping pliers is hinged to the base and is provided with a clamping chuck, and the telescopic device drives the pair of clamping pliers to rotate; a guiding sleeve is fixed on the base, a guiding rod is arranged in the guiding sleeve, a blocking ring is fixed at the upper end part of the guiding rod, a fastening nut is arranged at the lower end part of the guiding rod, the blocking ring is hinged to the clamping pliers through a pair of link rods, and a compression spring which is located between the blocking ring and the guiding sleeve is sleeved on the guiding rod. The self-locking rail clamping device is simple in structure and easy in production and can guarantee that the rail clamping device is firmly clamped on a rail and can not be disengaged under unexpected conditions, such as power outage and the like.

The transportation-cum-storage container (1) mainly consists of a plastic inner container (2), an outer grid shell (13) formed of metallic crosspieces and longitudinal pieces (14, 15) crossing each other, for housing therein the inner container (2), and a pallet base (20) having length / width dimensions conforming to the European Steel Community Standards. An upper edge (17) of each longitudinal piece (15) of the grid shell (13) and a double edge (37) of an upper edge forming shape (19) are projection-welded to each other by crosswise butting against each other at six locations. Then the outer edge forming shape (19) of the grid shell (13) has a flat upper rim (44) arranged along it, for bearing corner legs and intermediate legs (23 to 30) of the pallet base (20) of another pallet container (1) stacked thereon.

The invention relates to a pipe assembly with an anti-disengagement sealing structure. The pipe assembly comprises at least two pipes. A pipe-shaped insertion opening section is connected to one end of one pipe, a pipe-shaped bearing opening section is connected to one end of the other pipe, and the pipe assembly with the anti-disengagement sealing structure further comprises a sealing ring and ananti-disengagement part. The outer circumferential wall of the insertion opening section is provided with a sealing ring installation groove and an anti-disengagement part installation groove. The bearing opening section comprises a clamping section, a sealing bearing section and a jointing section. A first conical sealing section is arranged on the inner circumferential wall of the sealing bearing section, a limiting clamping groove is formed in the sealing bearing section, and the anti-disengagement part comprises an anti-disengagement body and an elastic anti-disengagement body. By means of the pipe assembly, the sealing bearing section is tightly matched with the sealing ring, the anti-disengagement part is automatically ejected and pressed in the limiting clamping groove between thesealing bearing section and the clamping section through the elastic anti-disengagement body arranged on the outer circumferential part, the sealing ring is effectively prevented from driving the pipes to axially rebound, installation is convenient, in addition, the sealing effect is ensured, disengagement cannot happen even if later-period geological sedimentation happens, and the service life islong.

A disposable wearing article (1A) capable of preventing a connection between front and rear body peripheral zones from being disconnected in use, comprising the front and rear body peripheral zones (4) and (6) and a crotch zone (5) positioned between the body peripheral zones (4) and (6), and engagement members (11) extending in the vertical direction which are fitted to the inner surfaces of both side parts (10) of the rear body peripheral zone (6). The engagement members (11) further comprise fixed parts (18) fixed to the side parts (10) of the rear body peripheral zone (6) and first free parts (19) extending from the fixed parts (18) to the lateral center of the rear body peripheral zone (6). Hooks (20) of mechanical fasteners are formed on the inner surfaces of the first free parts (19), and both side parts (10) of the rear body peripheral area (6) are disengageably fixed to the inner and outer surfaces of the front body peripheral zone (4) through the engagement members (11).

A device having an imaging function includes: a camera portion to capture optically an image of an object and to output the image as an image data; a display portion to perform an image displaying using the image data from the camera portion; and a control portion to decide a representative figure by extracting features of the image from the image data of a whole photographed screen and to control the display portion so that if a position of the representative figure is changed, the display portion performs an image displaying to which a process corresponding to the change is applied. If the change of device position can be detected from the photographed screen, it is possible to correct the covered area such that the part not to display does not come off the covered area, and it is also possible to report the change of the device position as occurrence of abnormal circumstances.

The safety tyre includes a rubber tyre and a hub, and features the hub, which includes a main hub with annular cavity for holding inflated inner tube and a hub holding plate fixed to the main hub. The annular cavity has several opening communicated to the inside of the rubber tyre in the outer wall, supporting rods in the openings, supporting boards in the inner ends of the supporting rods, and flexible pads between the inflated inner tube and the supporting boards. The present invention has the advantages of effective support on the blowout tyre, etc.

The invention relates to a structure and a method for welding a target material and a backboard, wherein the method for welding the target material and the backboard comprises the following steps: proThe invention relates to a structure and a method for welding a target material and a backboard, wherein the method for welding the target material and the backboard comprises the following steps: providing a tantalum target material; forming an intermediate layer on the welding surface of the tantalum target material; and performing welding operations on the intermediate layer through a hot isostviding a tantalum target material; forming an intermediate layer on the welding surface of the tantalum target material; and performing welding operations on the intermediate layer through a hot isostatic pressing method so as to weld a copper or copper alloy backboard to the tantalum target material. The method can perform extensive welding to effectively prevent metals form being oxidized and imatic pressing method so as to weld a copper or copper alloy backboard to the tantalum target material. The method can perform extensive welding to effectively prevent metals form being oxidized and improve the bonding strength between the tantalum target material and the copper or the copper alloy backboard, thus the tantalum target material cannot break away in the sputtering process so as to perprove the bonding strength between the tantalum target material and the copper or the copper alloy backboard, thus the tantalum target material cannot break away in the sputtering process so as to perform sputter coating normally.form sputter coating normally.
