Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, 2 and 3, the pipe orifice sealing device comprises a sleeve 1 for sleeving a pipe orifice to be sealed, wherein the sleeve is hinged with one end of a first connecting rod 2, and the other end of the first connecting rod is provided with a pressing plate 3 for pressing the inner wall of the pipe orifice to be sealed; the sleeve is axially and movably connected with a movable rod 4, the movable rod is hinged with one end of a second connecting rod 5, and the other end of the second connecting rod is hinged on the first connecting rod.
The sleeve is sleeved on the pipe orifice, the movable rod moves towards one side far away from the pipe orifice, the pressing plate is pressed, the pipe orifice can be sealed, and the method is simple and rapid. The friction between the pressure plate and the pipe wall can further enable the pipe orifice to be embedded into the slot, and the sealing effect is good.
In this embodiment, the hinge joint of the first link and the sleeve is preferably the joint of the movable rod and the sleeve, and is configured to allow the rotation angle of the first link to be as large as possible. In other embodiments, the sleeve can be hinged at other positions without affecting the implementation of the invention.
In this embodiment, first connecting rod is the two body of rods that set up in second connecting rod both sides, strengthens the stability of being connected between first connecting rod and the second connecting rod and the atress ability of first connecting rod.
In practical application, the first connecting rod and the second connecting rod are both provided with a plurality of connecting rods. This embodiment exemplifies four cases. The four first connecting rods and the four second connecting rods are radially and symmetrically wound on the movable rods.
One end of the sleeve, which is sleeved with the pipe orifice to be sealed, is provided with a slot, and the slot is used for being embedded into the pipe wall of the pipe orifice to be sealed. In this embodiment, the slots are arranged in such a way that the sleeve includes two concentric cylinders, and the slots are formed by the gaps between the two concentric cylinders. This is of course not the only embodiment of the socket according to the invention, for example, in other embodiments the sleeve may be provided as a solid cylinder with an annular recess provided thereon for use as the socket.
And a rubber sealing gasket is arranged in the slot.
The movable rod with the sleeve spiro union, the movable rod is kept away from the orificial one end fixedly connected with of treating sealed be used for rotatory the rim plate 6 of movable rod.
It should be noted that the screw joint is a preferred embodiment of the movable rod of the present invention, and the arrangement of the movable rod is not limited to the screw joint in other embodiments, for example, the sleeve may be connected to the movable rod through a linear bearing.
Further, the wheel disc and the movable rod are connected through the cross clamping groove in the embodiment. Other means of attachment, such as welding, are also possible in other embodiments.
The movable rod is hinged with one end of the second connecting rod through a bearing 7 arranged on the movable rod.
Under the condition that the movable rod is in threaded connection with the sleeve, the movable rod does axial movement and simultaneously necessarily does radial rotation movement. The movable rod is connected with the second connecting rod through the bearing, so that the second connecting rod does not need to rotate along with the movable rod, and the hinged part of the second connecting rod and the first connecting rod and the hinged part of the first connecting rod and the sleeve are prevented from bearing larger torsion.
The other end of the first connecting rod is hinged with the pressing plate. When the other end of the second connecting rod moves towards the inner wall of the pipe orifice, the pressure plate can rotate and keep close to the inner wall of the pipe orifice.
The first connecting rod is further connected with a pressing plate through a third connecting rod 8, one end of the third connecting rod is hinged with the pressing plate, and the other end of the third connecting rod is connected to the first connecting rod in a sliding mode. Furthermore, a sliding groove is formed in the first connecting rod, and the other end of the third connecting rod is connected to the sliding groove in a sliding mode through a bolt.
The third connecting rod can limit the pressure plate to a certain extent. Because the pressing plate is hinged with the first connecting rod, the pressing plate can rotate, and sometimes before use, the angle of the pressing plate is excessively deviated from the normal use range, and then needs to be adjusted. The third connecting rod is added to limit the rotating angle of the pressure plate, so that the angle of the pressure plate can not deviate too much and can be directly used without adjustment.
The pressing plate is an arc-shaped plate attached to the inner wall of the pipe orifice to be sealed. In the embodiment, the pipe orifice to be sealed is a circular pipe by default; in other embodiments, the orifice may be a non-circular shape such as a square tube, and the pressure plate may be supported to be attached to the orifice.
The pressing plate is provided with a plurality of arc-shaped teeth on one side close to the pipe orifice to be sealed.
And a rubber sealing ring 9 is arranged at the joint of the sleeve and the movable rod.
In addition, in fig. 1-3, the spout 10 is to be sealed.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention disclosed herein are intended to be covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
