Description

Technical Field

[0001] The utility model belongs to the technical field of electric manhole covers, and particularly relates to a sealing structure for an electric manhole cover lock bin. Background Technique

[0002] A manhole cover is used to cover a road or a deep well at home to prevent people or objects from falling. It can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. To ensure the fixing effect after the manhole cover is installed, an electric lock bin is installed on the manhole cover, and the manhole cover can be locked through the electric lock bin.

[0003] The existing electric manhole cover lock bins on the market have the following problems in actual use:

[0004] 1. When the traditional electric manhole cover lock bin is actually used, since the electric lock bin is located inside the wellhead and the inside of the wellhead is relatively humid with heavy moisture, after the traditional manhole cover and the electric lock bin are installed, the connection position between the manhole cover and the electric lock bin does not have a sealing effect, and at this time, moisture may enter the inside of the electric lock bin, resulting in poor sealing performance during use;

[0005] 2. During the use of most electric manhole cover lock bins, since a switch handle is installed on the top of the manhole cover, this switch handle usually protrudes from the manhole cover. When a vehicle passes over the manhole cover, it may press the switch handle, thereby causing damage to the switch handle and having poor protection performance during use. Content of the Utility Model

[0028] To better understand the purpose, structure and function of the present utility model, the following further describes in detail a power manhole cover lock chamber sealing structure of the present utility model with reference to the drawings.

[0029] As Figures 1-5 shown, a power manhole cover lock chamber sealing structure of the present utility model includes a manhole cover body 1. A fixing ring 3 is welded to the bottom of the manhole cover body 1. A clamping frame 4 is installed on the top of the fixing ring 3. The power chamber 2 is clamped to the bottom of the clamping frame 4. An L-shaped sealing ring 5 is adhered to the clamping frame 4. By installing the clamping frame 4, the clamping clip provides an installation position for the L-shaped sealing ring 5, which is very convenient in use. The side of the L-shaped sealing ring 5 is attached to the inner wall of the fixing ring 3, the other side of the L-shaped sealing ring 5 is attached to the surface of the power chamber 2, and the bottom of the L-shaped sealing ring 5 is attached to the bottom of the manhole cover body 1. By installing the L-shaped sealing ring 5, the installation position between the power chamber 2 and the cover body can be sealed by using the L-shaped sealing ring 5, so that moisture will not enter the power chamber 2 through the installation position between the power chamber 2 and the cover body, and the sealing performance is strong during use.

[0030] A switch handle 11 is installed on the top of the manhole cover body 1. An external thread ring 10 is welded to the top of the manhole cover body 1. An internal thread ring 9 is sleeved on the surface of the external thread ring 10. A protective plate 8 is welded to the top of the internal thread ring 9. The switch handle 11 is located inside the internal thread ring 9 and the protective plate 8. By installing the protective plate 8 and the internal thread ring 9, the internal thread ring 9 and the protective plate 8 can hide the switch handle 11, so that the switch handle 11 will not be squeezed, and the protection performance is strong during use.

[0031] An external threaded rod 6 is welded to the top of the fixing ring 3. The external threaded rod 6 passes through the clamping frame 4. A nut 7 is installed on the surface of the external threaded rod 6. One end of the nut 7 is attached to the surface of the clamping frame 4. By installing the external threaded rod 6 and the nut 7, the external threaded rod 6 passes through the clamping frame 4 and the nut 7 is installed on the surface of the external threaded rod 6 until one end of the nut 7 is attached to the surface of the clamping frame 4, which can provide a fixing effect for the clamping frame 4, and the stability is strong during use.

[0032] The surface of the internal thread ring 9 is welded with a support plate 13. The other end of the support plate 13 is welded with a support ring 12. The support plates 13 are distributed in a circular form. By installing the support ring 12 and the support plates 13, the support ring 12 and the support plates 13 can provide a level for the protection plate 8, so that the protection plate 8 will not protrude on the manhole cover body 1, which is very convenient to use.

[0033] The surface of the support ring 12 is welded with a dial plate 14. The dial plates 14 are distributed in a circular form. By installing the dial plates 14, when installing the internal thread ring 9, the dial plates 14 can be used to provide a force point. The support ring 12 is driven by the dial plates 14, and then the support ring 12 drives the internal thread ring 9 to rotate through the support plates 13, so as to install the internal thread ring 9 on the surface of the external thread ring 10, which is very convenient to use.

[0034] The nuts 7 are distributed in a circular form, and the external threaded rods 6 are distributed in a circular form. Through the distribution form of the installation of the external threaded rods 6 and the nuts 7, the fixing effect after the installation of the clamping frame 4 can be further improved, and the stability is strong during use.

[0035] The working principle of the power manhole cover lock chamber sealing structure: When using the power manhole cover lock chamber sealing structure, the clamping frame 4 should be installed on the fixed ring 3 first. When installing the clamping frame 4, the external threaded rod 6 on the fixed ring 3 is used to penetrate the clamping frame 4, and then a nut 7 is installed on the surface of the external threaded rod 6 until one end of the nut 7 fits against the surface of the clamping frame 4, which can provide a fixing effect for the clamping frame 4, and the stability is strong during use. Since the L-shaped sealing ring 5 is bonded inside the clamping frame 4, at this time, the side of the L-shaped sealing ring 5 fits against the inner wall of the fixed ring 3, and the other side of the L-shaped sealing ring 5 fits against the surface of the power chamber 2, and the bottom of the L-shaped sealing ring 5 fits against the bottom of the manhole cover body 1. At this time, by installing the L-shaped sealing ring 5, the installation position between the power chamber 2 and the cover body can be sealed by the L-shaped sealing ring 5, so that moisture will not enter the power chamber 2 through the installation position between the power chamber 2 and the cover body, and the sealing performance is strong during use. Finally, the protection plate 8 is installed. When installing the protection plate 8, the dial plate 14 can be used to provide a force point. The support ring 12 is driven by the dial plate 14, and then the support ring 12 drives the internal thread ring 9 to rotate through the support plates 13, so as to install the internal thread ring 9 on the surface of the external thread ring 10. At this time, the installation of the protection plate 8 is completed, and the switch handle 11 will be located inside the internal thread ring 9 and the protection plate 8. At this time, the internal thread ring 9 and the protection plate 8 can be used to hide the switch handle 11, so that the switch handle 11 will not be squeezed, and the protection performance is strong during use.
