Description

Technical Field

[0001] The utility model belongs to the technical field of drain valves, and in particular relates to a drain valve anti-loosening bracket. Background Art

[0002] Drain valve is an indispensable product in the water industry. Its main function is to control the flow direction, flow rate, pressure and other parameters of the fluid in order to achieve the normal operation of the drainage system. There are many types of drain valves. According to the power mode, they can be divided into automatic, power-driven and manual. According to the purpose and function, they can be divided into stop valves, check valves, ball valves, steam traps, etc. Different valves are suitable for different scenarios. Drain valves are mainly used in cities, buildings, enterprise water supply and drainage projects, industrial and domestic sewage treatment and water conservancy projects. For example, drain valves can be used to control the flow and water level in domestic water supply, fire protection systems and industrial water supply systems, and can also be used for drainage of sewer pipes to effectively control the water level.

[0003] During the installation process, some drain valves are often designed at the connection point of two suspended pipes, so the drain valve itself will also appear suspended. In order to ensure the stable operation of the drain valve and extend its service life, the installer will install a set of brackets at the bottom of the drain valve to provide the necessary support. However, after a period of use, the existing brackets often become loose, which inevitably affects its supporting effect and may cause the drain valve to no longer be stable. In order to overcome this problem and ensure the stability and safety of the drain valve, it is necessary to improve and optimize the existing bracket design. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 , the utility model provides the following technical solutions: a drain valve anti-loosening bracket, comprising a drain valve 1, and a clamp 2 is respectively installed on the butt pipes at both ends of the drain valve 1;

[0021] A mounting seat 3 is fixedly installed at the bottom of the clamp 2, a support rod 4 is provided at the bottom of the mounting seat 3, the bottom of the support rod 4 is installed on the outer wall of one side of the movable sleeve 5, the inner movable sleeve of the movable sleeve 5 is connected with a threaded rod 6, the bottom of the threaded rod 6 is fixedly installed on the surface of the base 7, the top of the threaded rod 6 is fixedly installed on the bottom of the tray 8, and a rotating component 9 is installed on the top of the movable sleeve 5.

[0022] Preferably, a rotating rod 401 is fixedly installed on the top of the support rod 4, and the rotating rod 401 is movably sleeved on the crossbar inside the mounting seat 3, and a fixing bolt 402 is threadedly installed on the outer wall of one side of the bottom of the support rod 4. The fixing bolt 402 penetrates the support rod 4 and is threadedly connected to the movable sleeve 5. The support rod 4 is symmetrically installed with two groups on both sides of the threaded rod 6.

[0023] During specific use, the distance between the top of the rotating rod 401 and the inner wall of the mounting seat 3 is greater than the radius of the rotating rod 401 when rotating. The bottom of the support rod 4 is an arc-shaped structure. During installation, the arc surface of the support rod 4 will fit perfectly with the outer wall of the movable sleeve 5.

[0024] Preferably, the surface of the tray 8 is an inwardly sunken concave structure, and the surface of the tray 8 is supported on the bottom of the drain valve 1 .

[0025] During specific use, the threaded rod 6 is located at the longitudinal midline of the valve body of the drain valve 1 , and the threaded rod 6 supports the bottom suspended area of ​​the valve body of the drain valve 1 through the tray 8 .

[0026] Preferably: the rotating component 9 includes a first annular groove 901, a second annular groove 902, a ball 903, a connecting rod 904 and an internal threaded sleeve 905, the internal threaded sleeve 905 is threadedly sleeved on the outer wall of the threaded rod 6, a circle of first annular groove 901 is provided on the outer wall at the bottom of the internal threaded sleeve 905, one side of the first annular groove 901 is connected to the second annular groove 902, a ball 903 is movably installed inside the second annular groove 902, and a connecting rod 904 is fixedly installed at the bottom of the ball 903.

[0027] During specific use, the rotating component 9 is rotated, and the rotating component 9 will move upward or downward through the threaded structure between the threaded rod 6, so that the rotating component 9 can drive the movable sleeve 5 at the bottom to move. After the bottom of the support rod 4 is docked with the movable sleeve 5, the movable sleeve 5 can drive the support rod 4 to move, thereby adjusting the tightness of the support rod 4 between the mounting seat 3 and the movable sleeve 5, thereby effectively preventing the loosening of the support structure.

[0028] Preferably, the bottom of the connecting rod 904 is fixedly mounted on the outer wall of the movable sleeve 5, the cross-sectional diameter of the second annular groove 902 is larger than the cross-sectional diameter of the first annular groove 901, and the diameters of the ball 903 and the connecting rod 904 match the corresponding diameters of the second annular groove 902 and the first annular groove 901.

[0029] When in use, the internal thread sleeve 905 rotates, which drives the second annular groove 902 and the first annular groove 901 inside thereof to rotate synchronously, so that the second annular groove 902 and the first annular groove 901 rotate on the outer wall of the ball 903 and the connecting rod 904. At this time, the bottom of the connecting rod 904 and the outer wall of the movable sleeve 5 are welded and fixedly connected, so that the ball 903 and the connecting rod 904 will not rotate with the rotation of the internal thread sleeve 905.

[0030] However, as the internal threaded sleeve 905 rotates upward or downward on the outer wall of the threaded rod 6, the second annular groove 902 and the first annular groove 901 will exert an upward or downward force on the ball 903 and the connecting rod 904, thereby driving the movable internal threaded sleeve 905 to move upward or downward on the movable sleeve 5.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
