[0002] The current anti-vibration device for hot water pipes mainly includes a pipe clamp and a compression spring. The pipe clamp clamps the hot water pipe, and the compression spring is located between the pipe clamp and the fixed surface, and the elasticity of the compression spring is used for shock absorption. This shock absorption device has some limitations. For example, it is impossible to set the shock absorption level according to the environment. If the function of adjusting the shock absorption level is required, different types of compression springs need to be replaced. However, replacing different types of compression springs requires re-disassembly and re-installation, which increases labor costs. Summary of the invention

[0006] As a further optimization of the present invention, the shell includes a box-shaped main body and a cover body covering the opening of the main body, and the cover body is detachably covered on the main body.

[0007] As a further optimization of the present invention, the bearing seat is fixed on the bottom of the main body, and the distance between the coil spring and the cover body does not exceed the thickness of the coil spring.

[0008] As a further optimization of the present invention, the blocking member is a bolt, the nut is arranged outside the shell, and the stud is threadedly connected to the shell.

[0009] As a further optimization of the present invention, three anti-vibration components are provided.

[0010] As a further optimization of the present invention, the clamp includes a base and a pressure cover; the base is fixed to one end of the screw rod, and one end of the base is provided with an arc-shaped first notch; the pressure cover is provided with an arc-shaped second notch, the first notch and the second notch have corresponding positions and shapes and work together to clamp the pipe; the base and the pressure cover are fixed by bolts.

[0011] As a further optimization of the present invention, a mounting seat is provided on the outer wall of the shell, and the shell is fixed to the external fixed end through the mounting seat.

[0012] As a further optimization of the present invention, a flange is provided in the middle of the side wall of the nut, one surface of the flange is pressed against the inner ring end of the bearing in the bearing seat, and the other surface of the flange supports the coil spring.

[0014] The present invention provides a vibration-proof structure for a hot water heating pipe, which converts the back-and-forth vibration of a clamp into a rotational motion through a screw rod and a nut, and then reverses the rotational motion through a torsion spring, thereby playing an anti-vibration role. This structure abandons the traditional compression spring vibration-proofing, because the compression spring will have a shaking effect that deviates from the axial direction during vibration-proofing, and this structure can effectively avoid this phenomenon. In addition, by adjusting the distance between the blocking member and the coil spring in the anti-vibration component, the anti-vibration function can be selected to be activated or not. After setting up a number of anti-vibration components, the anti-vibration strength can be adjusted by selecting the number of anti-vibration components to be activated.

DETAILED DESCRIPTION

[0019] like Figure 1 , 2 As shown, this embodiment includes a clamp 1, a screw rod 2 and a plurality of anti-vibration components 3.

[0020] The clamp 1 clamps the pipe. In this embodiment, the clamp 1 includes a base 1a and a gland 1b. The bottom of the base 1a is fixed to the top of the screw rod 2, and the top of the base 1a is provided with an arc-shaped first notch 1a1. The gland 1b is provided with an arc-shaped second notch 1b1, and the first notch 1a1 corresponds to the second notch 1b1 in position and shape. During installation, the first notch 1a1 and the second notch 1b1 are used to clamp the pipe, and then the base 1a and the gland 1b are fixed by bolts.

[0021] The three anti-vibration components 3 are arranged in sequence from top to bottom, and the anti-vibration components 3 are sleeved on the screw rod 2 .

[0022] In this embodiment, the anti-vibration assembly 3 includes a housing 3a, a nut 3b, a bearing seat 3c, a coil spring 3d and a blocking member 3e.

[0023] The housing 3a is fixed. In this embodiment, the housing 3a includes a box-shaped body 3a1 and a cover 3a2 covering the opening of the body 3a1. The cover 3a2 is detachably covered on the body 3a1 by screws. A mounting seat is provided on the outer wall of the body 3a1. The body 3a1 is fixed to the external fixed end by the mounting seat, and is specifically fixed by bolts.

[0024] The bearing seat 3c is arranged in the housing 3a, and the bearing seat 3c is fixed to the bottom of the body 3a1 by bolts.

[0025] The nut 3b is also arranged in the housing 3a, and the nut 3b is sleeved on the screw rod 2. The upper half of the side wall of the nut 3b is provided with a bayonet 3b1, and the lower half of the side wall of the nut 3b is sleeved in the bearing seat 3c. In order to facilitate the installation and limiting, the present embodiment is provided with a flange 3b2 in the middle of the side wall of the nut 3b, and the bottom surface of the flange 3b2 is pressed against the inner ring end of the bearing in the bearing seat 3c. The flange 3b2 can play a role of lifting and supporting on the one hand, and can play a role of isolating the coil spring 3d and the bearing seat 3c on the other hand to avoid friction between the two.

[0026] The coil spring 3d is arranged in the housing 3a, and the coil spring 3d is sleeved on the upper half of the side wall of the nut 3b. The inner ring stopper 3d1 of the coil spring 3d is inserted on the bayonet 3b1, and the coil spring 3d is supported by the flange 3b2. In this embodiment, the distance between the coil spring 3d and the cover body 3a2 does not exceed the thickness of the coil spring 3d. On the one hand, the size of the anti-vibration component 3 is compressed, making the anti-vibration component 3 appear small, and on the other hand, the cover body 3a2 plays a role in limiting the coil spring 3d to prevent the coil spring 3d from being separated from the nut 3b.

[0027] One end of the blocking member 3e is inserted into the housing 3a from the outside, and the other end of the blocking member 3e is arranged outside the housing 3a. By adjusting the blocking member 3e, one end of the blocking member 3e can block or disengage the outer ring blocking piece 3d2 of the coil spring 3d. Specifically, the blocking member 3e of this embodiment directly adopts a bolt, the nut is arranged outside the housing 3a, and the stud is threadedly connected to the housing 3a, which is low in cost and easy to adjust.

[0028] As a preferred structure of another embodiment, the flange 3b2 is stepped, the smaller surface of the flange 3b2 is pressed against the inner ring end of the bearing in the bearing seat 3c, and the larger surface of the flange 3b2 supports the coil spring 3d.

[0029] When in use, the up and down vibration of the pipeline drives the screw rod 2 to float up and down, and the up and down floating of the screw rod 2 drives the nut 3b to rotate. The rotation of the nut 3b will be hindered by the force of the coil spring 3d. The force of the coil spring 3d is used to alleviate the rotation amplitude of the nut 3b, thereby relieving the up and down floating of the screw rod 2.

[0030] In the present embodiment, the coil spring 3d can play a role mainly because the blocking member 3e resists the outer ring baffle 3d2 of the coil spring 3d. Therefore, when the distance between the blocking member 3e and the outer ring baffle 3d2 is adjusted to make the two disengaged, the coil spring 3d will no longer work. At this time, the coil spring 3d will rotate with the nut 3b. With this structure, the anti-vibration function can be started or abandoned at any time. Of course, this requires setting an initial position. When the screw rod 2 is in the initial position, the blocking member 3e can extend into and block the outer ring baffle 3d2. Even if the coil spring 3d will rotate with the nut 3b, after the screw rod 2 returns to the initial position, the blocking member 3e can be adjusted to still make the blocking member 3e block the outer ring baffle 3d2.

[0031] Three anti-vibration components 3 are provided to achieve three-level anti-vibration adjustment. In other embodiments, two or other numbers of anti-vibration components 3 may be provided to achieve two-level or other level adjustment.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
