Description
Technical field
The utility model relates to well lid technical field, pours in down a chimney well lid in particular to one.
Background technology
In city, all kinds of city planting ductwork is crisscross, road is also a mass of the active well of all kinds of city planting ductwork, the situation of pouring in down a chimney easily is produced when rainwater or the larger situation of surface drainage amount, and existing well lid is many times when pouring in down a chimney, can be flushed away or be shifted, vehicle and personnel easily drop to down-hole, cause the loss of the person and property.
Utility model content
The purpose of this utility model is to provide one to pour in down a chimney well lid, to solve the deficiencies in the prior art.
For realizing the utility model object, the technical scheme of employing is:
One pours in down a chimney well lid, comprises well seat and well lid, it is characterized in that, described well lid is upper and lower cover plates, and the periphery of lower cover matches with the inner headed face of well seat, and upper cover plate contacts with well seat upper surface and coordinates; Described well lid is provided with multiple counter sink, and the macropore height of counter sink is greater than well lid and installs the distance of rear well lid lower surface to well seat upper surface; Be provided with screw rod in described counter sink, screw rod lower end is connected with well seat threaded engagement; Be provided with gripper shoe between described lower cover and well seat, gripper shoe is net structure.
Further, the multiple counter sinks on described well lid are uniformly distributed.
The beneficial effects of the utility model are,
When the rainwater in well pours in down a chimney, due to screw rod and well seat threaded engagement, well lid is moved up along screw rod, and after the lower cover of well lid exceeds well seat, rainwater starts to discharge, after the rainwater in well no longer pours in down a chimney, well lid, under self gravitation effect, covers well seat along screw rod, thus after effectively avoiding well lid to be flushed away or being shifted, vehicle and personnel easily drop to down-hole, cause the loss of the person and property.
In addition, after well lid is by breakage, gripper shoe can be blocked the people fallen and wait object, and compared with prior art, well lid of the present utility model can effectively prevent people etc. from crashing in well, avoids injures and deaths and property loss etc.; Also there is the structural strength strengthening well lid simultaneously, avoid being damaged by pressure distortion in well lid use procedure and impact uses.
Accompanying drawing explanation
Fig. 1 is the structural representation pouring in down a chimney well lid that the utility model provides.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1 is shown, and one that the utility model provides pours in down a chimney well lid, comprising: well seat 1, well lid 2, upper cover plate 21, lower cover 22, screw rod 3 and gripper shoe 4.Described well lid 2 is upper and lower cover plates, and the periphery of lower cover 22 matches with the inner headed face of well seat 1, and upper cover plate 21 contacts with well seat 1 upper surface and coordinates; Described well lid 2 is provided with multiple counter sink, and the macropore height of counter sink is greater than well lid 2 and installs the distance of rear well lid 2 lower surface to well seat 1 upper surface; Be provided with screw rod 3 in described counter sink, screw rod 3 lower end is connected with well seat threaded engagement; Be provided with gripper shoe 4 between described lower cover 22 and well seat 1, gripper shoe 4 is in net structure; Multiple counter sinks on described well lid 2 are uniformly distributed.
When the rainwater in well pours in down a chimney, due to screw rod 3 and well seat 1 threaded engagement, well lid 2 is moved up along screw rod 3, and after the lower cover 22 of well lid 2 exceeds well seat 1, rainwater starts to discharge, after the rainwater in well no longer pours in down a chimney, well lid 2, under self gravitation effect, covers well seat 1 along screw rod 3, thus after effectively avoiding well lid 2 to be flushed away or being shifted, vehicle and personnel easily drop to down-hole, cause the loss of the person and property;
After well lid 2 is by breakage, gripper shoe 4 can be blocked the people fallen and wait object, and compared with prior art, well lid 2 of the present utility model can effectively prevent people etc. from crashing in well, avoids injures and deaths and property loss etc.; Also there is the structural strength strengthening well lid 2 simultaneously, avoid being damaged by pressure distortion in well lid 2 use procedure and impact uses.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
