Description

Technical Field

[0001] The utility model relates to the field of pressure equalizing balls, in particular to a novel pressure equalizing ball. Background Art

[0002] The pressure-equalizing ball is based on a sphere made of copper sheet metal or aluminum sheet, and is coated with insulating materials such as insulating paper pulp. Usually the shape and size of the pressure-equalizing ball are provided by the user, or the user can directly provide copper (aluminum) products for paper coating.

[0003] The traditional pressure equalizing ball is provided with a flange inside, and a certain number of fixing holes are opened on the flange. This type of flange needs to be used with flanges of the same size during installation. If flanges of different sizes are encountered, they cannot be matched. It is necessary to drill holes in the flange or customize the flange, which greatly increases the user's cost of use and reduces production efficiency. At the same time, the flange welded to the inner wall is prone to cracks at the connection, and the stability needs to be improved. Utility Model Content

[0004] The utility model aims to provide a novel pressure equalizing ball which is easy to maintain, not prone to cracks and can adapt to flanges with different diameters.

[0005] The purpose of the utility model is achieved as follows: a new type of equalizing pressure ball, including a sphere and a flange arranged inside the sphere; a flange through hole is provided in the center of the flange, and a sliding track extends to the flange through hole in all directions, and the outer periphery of the flange through hole is fixedly connected by a pressure ring; a slider is provided in the sliding track, and a slider through hole is provided on the slider; four groups of connecting rods are provided on the flange, and abutment seats are provided on the upper parts of the connecting rods, and the ends of the connecting rods pass through the top plate of the sphere and are fixedly connected by bolts.

[0006] Preferably, a connecting seat is provided between the connecting rod and the flange, and the connecting seat is integrally connected to the connecting rod.

[0010] Preferably, a countersunk hole is provided on the flange body at the periphery of the flange through hole from the bottom upward, and the pressure ring is fixed to the flange by countersunk bolts.

[0011] Compared with the prior art, the utility model is beneficial in that:

[0012] 1. Use a movable slider and set a slider through hole with a thread on the slider, so that the centers of the slider through holes of multiple groups of sliders can form circles with different diameters. Therefore, when facing flanges of different sizes, you only need to adjust the position of the slider; at the same time, connect the slider through hole with bolts to complete the connection between the flange and the flange;

[0013] 2. Use connecting rods to fix the flange and the top plate of the sphere to avoid welding the flange to the inside of the sphere, which completely solves the problem of cracks at the connection between the flange and the inner wall of the sphere and improves the stability of the pressure equalizing ball after use.

DETAILED DESCRIPTION

[0018] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0019] It should be noted that in the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the utility model product is usually placed when in use, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. Terms such as "horizontal", "vertical", and "overhanging" do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 1-3 As shown, a new type of equalizing pressure ball includes a sphere 1 and a flange 2 arranged inside the sphere 1; a flange through hole 201 is provided in the center of the flange 2, and a sliding track 202 extends to the flange through hole 201 in all directions, and the outer periphery of the flange through hole 201 is fixedly connected by a pressing ring 3; a slider 4 is provided in the sliding track 202, and a slider through hole 401 is provided on the slider 4; four groups of connecting rods 5 are provided on the flange 2, and an abutment seat 501 is provided on the upper part of the connecting rod 5, and the end of the connecting rod 5 passes through the top plate of the sphere 1 and is fixedly connected by bolts.

[0022] like Figure 1 As shown, a connecting seat 6 is provided between the connecting rod 5 and the flange 2. The connecting seat 6 is integrally connected to the connecting rod 5. The connecting seat increases the connection area between the connecting rod and the flange, thereby increasing the connection strength between the connecting rod and the flange.

[0023] like Figure 1As shown, a top plate through hole 101 corresponding to the connecting rod 5 is provided on the top plate of the sphere. The end of the connecting rod 5 passes through the top plate through hole 101 and is fixed to the top plate of the sphere by bolts, and a sealing gasket 7 is provided between the bolt and the top plate of the sphere and between the abutment seat and the top plate of the sphere. The connecting rod passes through the top plate of the sphere until the top plate of the sphere abuts against the abutment seat and is then tightened by a nut on the outside. The provided sealing gasket not only buffers the strength of hard contact, but also improves the sealing performance to prevent external rainwater from seeping into the interior.

[0024] like Figure 2-3 As shown, limiting grooves 402 are provided on both sides of the slider 4, and the slider 4 is engaged in the sliding track 202 through the limiting grooves 402. A thread is provided in the slider through hole. When installing the slider, the pressure ring is removed, and then the slider is matched with the sliding track from the flange through hole area. After multiple sliders are installed, the pressure ring can be fixed. The pressure ring can prevent the slider from sliding out and play a limiting role.

[0025] like Figure 1 As shown, a ruler is provided on the side of the sliding track 202, and one side of the ruler is set on the bottom side of the flange (not shown in the figure); when the flange is installed, the slider can be adjusted according to the fixed diameter of the flange, and the ruler can be used as a reference to ensure that the slider can be moved into place at one time, which is convenient for subsequent flange docking installation.

[0026] like Figure 1 As shown, a countersunk hole is provided on the flange body at the outer periphery of the flange through hole 201 from the bottom upward, and the pressure ring is fixed to the flange by a countersunk bolt. The countersunk bolt passes through the flange and the pressure ring from the bottom and is locked by a nut. The countersunk bolt is embedded in the countersunk hole, which avoids the plane where the bottom of the bolt is lower than the plane where the bottom of the slider is located, thereby ensuring that the flange can directly contact the slider.

[0027] The working principle of the utility model is explained as follows: when installing the flange, the connecting rod is matched with the through hole of the top plate and then fixed by rotating through a nut, and then the position of the slider is adjusted according to the diameter of the connecting flange, which can be moved with a ruler, and then the flange and the flange are connected by bolts.

[0028] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
