Abstract

(57) [Summary] (Modified) [Purpose] To provide a protector capable of easily fixing an iron plate or the like loosely fitted to a skirt to an iron lid receiving frame integrally having the skirt. [Structure] Two long and short protectors 1 and 3 are slidably fitted to each other, and a plurality of lower claws are formed on an upper edge portion of the short protector 1, and a skirt 6 is formed on the claw 6.
The skirt 6 of the iron lid receiving frame 3 which is integrated with the above is press-fitted and fixed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 In order to improve the workability of the installation of an iron lid, which is an opening and closing port for structures such as underground oil storage tanks that are not susceptible to the intrusion of water from the outside, an integrated cart is provided under the iron lid receiving frame. The present invention relates to a structure in which a protector made of an iron plate or the like that is loosely fitted to the outer circumference or the inner circumference of the skirt is mounted.

[0002]

[Prior art]

 Conventionally, there is a configuration in which an integral skirt is formed in the lower portion of an iron lid receiving frame, and a protector made of an iron plate or the like is loosely fitted to the outer circumference or the inner circumference of the skirt.

[0003]

[Problems to be solved by the device]

 The main point of the present invention is to use a protector with a relatively short length in view of the drawbacks that the length of the protector that is conventionally attached is long according to the required size, and many types are required to match the required size each time. The technical problem to be solved is to combine a long protector with the assumption that the long and short protectors are slidably adjusted and to fix the short protector to the skirt of the iron lid receiving frame in advance.

[0004]

[Means for Solving the Problems]

 The technical means for solving the above-mentioned problems is that the skirt of the iron lid receiving frame has a conventional structure, the protector has a slide combination structure of two long and short, and the shorter protector has a fitting portion with the skirt. A plurality of claws are formed by cutting and bending the upper edge of the claw so that the openings of the claws are on the lower side.

[0005]

[Action]

 The protector according to the present invention has a structure of two long and short, and the short protector has a plurality of claws at the upper edge of which the openings are on the lower side, and the iron lid receiving frame is provided from above the protector. When the skirt part is placed and a strong pressure is applied from above, the claws are fitted while being pressed, and the claws are open on the lower side. It elastically digs into the side of the skirt and is securely fixed. However, since the other long protector of the protector is a slidable combination, the height of the iron lid receiving frame and all protectors stacked can be adjusted steplessly within a certain range. Is.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a short protector in the form of a loop made of an iron plate or the like, and 2 is a plurality of claws formed by connecting a part formed near the upper edge of the protector 1 and bending the b part inward. 2 is an assembled state, 3 is a long protector that freely fits vertically with the protector 1, 5 is a receiving frame on which an iron lid 4 is placed and a skirt 6 is integrated, and FIG. The protector 1 is fitted into the skirt 6 not at the outer periphery but at the inner periphery by the protector 1'and the bending direction is reversed.

[0007]

[Effect of device]

 As described above, according to the present invention, the fixing structure can be obtained only by forming the claws 2 (2 ') on the upper edge of the protector 1 (1') having a short length by pressing or the like. The method is simply press-fitting, and the general method of screwing requires screw holes for the skirt 6 and tapping work, which is a simple structure without doing this. The total stacking height H can be selected steplessly by sliding and sliding 3 and 3, which has the effect that the height can be freely adjusted at the installation site. In the embodiment, the skirt 6 and the protectors 1 and 3 are shown in a cylindrical shape, but this is equivalent to a square tube.
