Technical Field

[0001] The utility model relates to the technical field of electric auxiliary facilities, in particular to a manhole cover opener. Background Art

[0002] With the development of society, the laying of power lines has become increasingly perfect. In towns, the lines are laid along underground pipelines. The pipelines are equipped with manhole covers. The manhole covers are round or rectangular and have two round holes on them for opening.

[0003] The common opening method of the manhole cover requires three people to cooperate at the same time, which is not only inefficient but also requires high manpower costs. Therefore, a manhole cover opener is proposed. Utility Model Content

[0004] The utility model aims to solve the problem that the opening of the manhole cover in the prior art is not only inefficient but also requires high manpower costs, and proposes a manhole cover opener.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A manhole cover opener comprises a casing, a connecting rod, a movable cross bar and a handle, wherein the connecting rod is vertically inserted into the interior of the casing, and both ends of the connecting rod extend to the outside of the casing, a U-shaped groove is provided at the lower end of the connecting rod, the movable cross bar is located inside the U-shaped groove and is rotatably connected via a rotating shaft, and the handle is fixedly arranged at the upper end of the connecting rod.

[0007] Preferably, two limiting sliding blocks are symmetrically fixedly provided on the rod wall of the connecting rod, and a limiting sliding opening matched with the limiting sliding blocks is provided on the tube wall of the sleeve.

[0008] Preferably, the movable cross bar adopts a willow leaf-shaped structure.

[0009] Preferably, a prying opening is provided at the lower end of one side of the tube wall of the sleeve, and the prying opening is an arc-shaped opening.

[0010] Preferably, a return groove is provided on the tube wall of the sleeve and on the other side away from the prying opening.

[0011] Preferably, both ends of the handle are fixed with anti-slip sleeves.

[0012] Compared with the prior art, the utility model provides a manhole cover opener, which has the following beneficial effects:

[0013] 1. The manhole cover opener is equipped with a casing, a connecting rod, a movable cross bar, a handle and a rotating shaft. The man first holds the casing tightly, and then pushes the connecting rod to move inside the casing, so that the lower end of the connecting rod together with the movable cross bar is inserted into the round hole of the manhole cover, and then the connecting rod is shaken left and right. When the movable cross bar is vertical to the connecting rod, the casing and the connecting rod are lifted upward to open the manhole cover.

[0014] 2. The manhole cover opener is provided with a limit slider and a limit sliding mouth. When the connecting rod moves inside the casing, the limit slider moves inside the limit sliding mouth, which can limit the position of the connecting rod inside the casing, avoid the phenomenon of the connecting rod rotating inside the casing, and improve the stability of the connecting rod inside the casing.

[0015] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. During the process of opening the manhole cover, the utility model can be operated by a single person, which greatly saves manpower and material resources and improves construction efficiency.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0022] Reference Figure 1-3 A manhole cover opener includes a casing 1, a connecting rod 2, a movable cross bar 3 and a handle 4. The connecting rod 2 is vertically inserted into the casing 1, and both ends of the connecting rod 2 extend to the outside of the casing 1. A U-shaped groove 5 is opened at the lower end of the connecting rod 2. The movable cross bar 3 is located inside the U-shaped groove 5 and is rotatably connected through a rotating shaft 6. The movable cross bar 3 adopts a willow leaf shape structure. The handle 4 is fixedly arranged at the upper end of the connecting rod 2. Both ends of the handle 4 are fixedly sleeved with anti-slip sleeves 11. The anti-slip sleeves 11 can increase the friction resistance between the hand and the handle 4, thereby improving the stability of holding the handle 4.

[0023] Two limit sliders 7 are symmetrically fixed on the rod wall of the connecting rod 2, and a limit sliding opening 8 matching with the limit sliders 7 is provided on the tube wall of the sleeve 1. When the connecting rod 2 moves inside the sleeve 1, the limit slider 7 moves inside the limit sliding opening 8, which can limit the position of the connecting rod 2 inside the sleeve 1, avoid the connecting rod 2 from rotating inside the sleeve 1, and improve the stability of the connecting rod 2 inside the sleeve 1.

[0024] A prying opening 9 is provided at the lower end of one side of the pipe wall of the casing 1, and the prying opening 9 is an arc-shaped opening. The prying opening 9 can provide support for the casing 1, making it convenient to tilt and pry up the manhole cover; a return groove 10 is provided on the other side of the pipe wall of the casing 1 away from the prying opening 9.

[0025] In the utility model, when in use, the user first holds the casing 1 tightly, and then pushes the connecting rod 2 to move inside the casing 1, so that the lower end of the connecting rod 2 together with the movable cross bar 3 is inserted into the circular hole of the manhole cover, and then the casing 1 and the connecting rod 2 are shaken left and right, and when the movable cross bar 3 is vertical to the connecting rod 2, the casing 1 and the connecting rod 2 are lifted upward, so that the manhole cover can be opened.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
