Description
Technical Field
The utility model relates to a well lid technical field especially belongs to an opening tool that is used for assisting ground well lid to open.
Background
When the manhole cover is opened by needs because of work maintenance and the like, at present, the iron hook is usually held and the opening hole on the manhole cover is inserted, the manhole cover is lifted afterwards, the operation is inconvenient, the labor intensity is high, and the phenomenon that the manhole cover is rusted or settled easily occurs because the sun and rain and the vehicle roll all year round, so that the difficulty of opening the manhole cover is increased, even the manhole cover can be lifted by prying the manhole cover, but the workload of workers can be greatly increased undoubtedly in the operation mode.
Disclosure of Invention
An object of the utility model is to provide an auxiliary opening tool of ground well lid promptly to reach the well lid and open, close and reduce staff's intensity of labour's purpose.
The utility model provides an auxiliary opening tool of manhole cover, its characterized in that, including upper base member and lower base member, upper base member is annular base member, is provided with the gripping part in the annular base member, the gripping part include gripping plate, connecting rod, two connecting rods run through the both ends of gripping plate and arrange and with upper base member coupling in the upper and lower both ends of connecting rod, gripping plate and connecting rod sliding connection, still be provided with the spring of overcoat on the connecting rod between gripping plate and annular base member; the lower base member bottom has the open slot, is provided with backstop part in the open slot, including connecting axle, first connecting plate, second connecting plate and backstop board, the inside connecting axle that has of lower base member, the connecting axle runs through lower base member setting, and extend to the base member inside and with the board connection of gripping in the upper end, extend to the open slot in the lower extreme and couple with first connecting plate, the one end of first connecting plate articulated with the one end of second connecting plate, the other end of second connecting plate is articulated in the middle part of backstop board, the backstop board still articulate on lower base member.
Further, in the initial state that the spring in the upper base body is not compressed, the direction of the stop plate is parallel to the direction of the lower base body.
Further, the direction of the stop plate is perpendicular to the direction of the lower base body in the state of the maximum compression amount of the spring in the upper base body.
Furthermore, the hinge point of the stop plate and the second connecting plate and the hinge point of the stop plate and the lower base body are arranged in a front-back staggered mode.
The utility model provides a supplementary opening tool of ground well lid through the part that grips of ground well lid top, acts on the backstop part of ground well lid below for the well lid is opened and is closed very convenient and fast, and the operating personnel's that has significantly reduced intensity of labour has simple structure, practical positive effect.

The accompanying drawings partially disclose embodiments of the present invention, in which,
fig. 1 is a schematic structural view of the present invention;
fig. 2 is a top view of the present invention;
FIG. 3 is a schematic cross-sectional view taken along line A-A in FIG. 2;
fig. 4 is a schematic view of an application state of the present invention.
Detailed Description
As shown in figures 1-4, the utility model provides a supplementary opening tool of ground well lid, including last base member 1 and lower base member 2, go up the base member and be the annular base member, the inside part that is provided with of annular base member grips the part. Specifically, the holding part comprises a holding plate 3 and two connecting rods 4, the two connecting rods penetrate through the two ends of the holding plate and are arranged and connected with the upper base body at the upper end and the lower end of each connecting rod, the holding plate is connected with the connecting rods in a sliding mode, a spring 5 sleeved on the connecting rods is further arranged between the holding plate and the annular base body, when the holding plate is lifted upwards, the spring is compressed, and after the upward lifting force is released, the holding plate slides downwards to the initial position along the connecting rods under the action of the spring. The base member bottom has the open slot down, be provided with backstop part in the open slot, backstop part includes first connecting plate 6, second connecting plate 7 and backstop board 8, the inside connecting axle 9 that has of base member down, the connecting axle runs through base member setting down, and the upper end of connecting axle extends to the base member inside and with the connection of holding the board, the lower extreme of connecting axle extends to in the open slot and links with first connecting plate, and simultaneously, the one end of first connecting plate is articulated with the one end of second connecting plate, the other end of second connecting plate is articulated in the backstop board, the backstop board still articulates on lower base member, wherein, the pin joint of backstop board and second connecting plate and the pin joint of backstop board and lower base member are front. And in the embodiment, the second connecting plate is hinged to the middle part of the stop plate. When the holding plate moves upwards along the connecting rod in a lifting manner, the holding plate acts on the stopping component through the connecting shaft, and then the holding plate is connected with the connecting shaft through the first connecting plate and the second connecting plate, acts on the stopping plate, and drives the stopping plate to move from a state parallel to the direction of the lower base body to a state perpendicular to the direction of the lower base body, so that the holding component is prevented from being separated from the opening hole of the manhole cover 10, and the effect of fixing the manhole cover is achieved.
Furthermore, in the embodiment of the present invention, preferably, in the initial state where the spring inside the upper base body is not compressed, the direction of the stop plate is parallel to the direction of the lower base body; under the state of the maximum compression amount of the spring in the upper base body, the direction of the stop plate is perpendicular to the direction of the lower base body.
