Utility model content
The technical problems to be solved in the utility model and the technical assignment of proposition be prior art is carried out improve with
It improves, a kind of cable duct concrete cover opening and closing tool is provided, to realize the carrying to the safe ready of concrete cover as mesh
's.For this purpose, the utility model takes following technical scheme.
A kind of cable duct concrete cover opening and closing tool, including handle, 2 first screw rods, 2 second screw rods, 2 interior spiral shells
Line connects sleeve and 2 pre-buried inner thread sleeves, and 2 first screw rods are connected to the shaking hands under the both ends of position of handle
Side, second screw rod are double threaded screw, and the lower end of first screw rod and the upper end of the second screw rod are connected by internal screw thread
Female connector cylinder is detachably connected, and the pre-buried inner thread sleeve is embedded in concrete cover in advance, neutral threaded hole at least upward one
End opening, lower end and the pre-buried inner thread sleeve of second screw rod are detachably connected.In use, 2 the second screw rods are revolved
Enter in the pre-buried inner thread sleeve of concrete cover, internal screw thread connection sleeve is all then screwed in the second screw rod, under handle
2 the first screw rods alignment internal screw thread connect sleeve, then screw in the first screw rod lower end back up, realize to the first screw rod and
The connection of second screw rod, i.e., available hand, which is held handle and carried upwards, mentions concrete cover, it is convenient to realize single palm top, remove
Fortune is convenient, and structure is simple, highly-safe without hidden danger of hurting sb.'s feelings, and can effectively meet O&M requirement.
As further improving and supplementing to above-mentioned technical proposal, the utility model further includes that following supplementary technology is special
Sign.
The internal screw thread connection bushing core is to run through screw thread in the same direction, when the first screw rod and the second screw rod connect, screw thread
Direction is consistent with the internal screw thread connection hand of spiral of sleeve.Relative to other helicitic textures, perforative screw connection structure in the same direction
Simply, easy to operate.
The handle material is round steel.Round steel intensity is high, at low cost, and cutting is simple.
It is welded connecting between the handle and 2 first screw rods.Welding manner connection, structure is simple, securely, intensity
Height, it is easily manufactured.
The outer peripheral surface of the pre-buried inner thread sleeve is equipped with the lateral outer lug or inner groovy for preventing axial movement.It is mixed
After solidifying earth mulch plate pours, by preventing the structure of axial movement from can effectively prevent concrete cover when being lifted upwards with tool
The case where being detached from pre-buried inner thread sleeve under gravity generation.
The utility model has the advantages that this tool construction is simple, it is easy to operate, it is convenient to realize single palm top, convenient in carrying, nothing
It hurts sb.'s feelings hidden danger, it is highly-safe, it can effectively meet O&M requirement.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
In figure: 1- handle；The first screw rod of 2-；The second screw rod of 3-；4- internal screw thread connects sleeve；The pre-buried inner thread sleeve of 5-；
6- concrete cover.
Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 1, a kind of cable duct concrete cover opens and closes tool, including 1,2 first screw rod 2,2 second of handle
3,2 internal screw thread connection pre-buried 5,2 first screw rods 2 of inner thread sleeve of sleeve 4 and 2 of screw rod are connected to the handshake part of handle 1
The downside at position both ends, the second screw rod 3 are double threaded screw, and the upper end of the lower end of the first screw rod 2 and the second screw rod 3 passes through internal screw thread company
Female connector cylinder 4 is detachably connected, and pre-buried inner thread sleeve 5 is embedded in advance in concrete cover 6, and neutral threaded hole at least open upward by one end
Mouthful, the lower end of the second screw rod 3 is detachably connected with pre-buried inner thread sleeve 5.
Internal screw thread connection 4 center of sleeve is to run through screw thread in the same direction for operating easily, and the first screw rod 2 and the second screw rod 3 connect
When connecing, hand of spiral is consistent with the internal screw thread connection hand of spiral of sleeve 4.Relative to other helicitic textures, it is threadedly coupled in the same direction
Simply, easy to operate.
In order to reduce cost, 1 material of handle is round steel.Round steel intensity is high, at low cost, and cutting is simple.
In order to keep connection simple secured, it is welded to connect between the first screw rod of handle 1 and 2 piece 2.Welding manner connection, knot
Structure is simple, and securely, intensity is high, easily manufactured.
In lifting, pre-buried inner thread sleeve 5 is set on the outer peripheral surface of pre-buried inner thread sleeve 5 from being axially disengaging in order to prevent
There are the lateral outer lug or inner groovy for preventing axial movement.After concrete cover 6 pours, by preventing the structure of axial movement,
