Description

Technical Field

[0001] The utility model belongs to the field of vibration reduction and noise reduction, and particularly relates to a vibration isolation unit connection structure. Background Art

[0002] The vibration isolation unit is generally connected to the vibration isolation platform, and the vibration of the working machine on the vibration isolation platform is reduced by the elastic parts in the vibration isolation unit. The existing vibration isolation unit generally includes a base and an upper shell, and an elastic part is arranged between the base and the upper shell. This type of vibration isolation unit generally has the following problems: 1. Since it is not precisely machined, unlike rigid parts, the length of each elastic part (usually a spring) in the relaxed state is quite different, resulting in different distances between the upper shells and the bases of multiple vibration isolation units, which is not conducive to subsequent installation and positioning on the vibration isolation platform; 2. Each part is produced separately by the factory and assembled by workers after being delivered to the purchaser. In practice, workers often assemble at will, which may lead to misalignment between the base and the upper shell. Although it can be used normally, it is different from the expected effect. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a vibration isolation unit connection structure.

[0004] The purpose of the present utility model is achieved in the following way: a vibration isolation unit connection structure, including a base 1 and an upper shell 2, the base 1 and the upper shell 2 are connected by an elastic member, the base 1 and one of the upper shell 2 are connected by a hook 3, the base 1 and the other connection hanger in the upper shell 2, the hook 3 and the hanger are hooked together, and when the hook 3 and the hanger are hooked together, the elastic member is in a compressed state.

[0005] Furthermore, the outer cylinder 11 is fixed on the top of the base 1, and the hanger is a hanging rod 12, which is fixed to the outer cylinder 11.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] In the present invention, unless otherwise expressly specified and limited, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention 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 operate in a specific orientation, and therefore should not be understood as a limitation to the present invention.

[0018] As attached Figure 1-2 As shown, a vibration isolation unit connection structure includes a base 1 and an upper shell 2, wherein the base 1 and the upper shell 2 are connected by an elastic member, the base 1 and one of the upper shell 2 are connected by a hook 3, and the base 1 and the other connecting member in the upper shell 2 are connected by a hanger, and the hook 3 and the hanger are hooked together. When the hook 3 and the hanger are hooked together, the elastic member is in a compressed state.

[0019] In response to the first problem in the background technology, the elastic part is pre-tightened through a hook connection, so that the distance between the upper shell 2 and the base 1 of multiple vibration isolation units is basically the same during actual use and only depends on the length of the hook 3; in response to the second problem in the background technology, through the cooperation between the hook 3 and the hanger, an additional positioning is provided between the upper shell 2 and the base 1, so that the workers will not misalign the two during installation.

[0020] Further, as attached Figure 3 As shown, the outer cylinder 11 is fixed on the top of the base 1, and the hanger is a hanging rod 12, which is fixed to the outer cylinder 11. The hook 3 includes a rod-shaped structure fixedly connected to the upper shell 2 at the top, and a cantilever extends to one side from the bottom of the rod-shaped structure. A hanging groove 31 that cooperates with the hanging rod 12 is provided on the cantilever. Preferably, the hanging rod 12 is a polygonal rod, and the hanging groove 31 is a polygonal groove that cooperates with it. A limiting plate is fixed to the outer end of the hanging rod 12, which as a whole serves to limit the rotation of the hook 3 in the horizontal direction.

[0021] The hook 3 and the hanging rod 12 can be one each, which are arranged in the middle of the elastic member to play a pulling role, but preferably and further, there are two hooks 3 and two hanging rods 12 respectively. The two hooks 3 are respectively located on both sides of the outer tube 11, and the extension directions of the cantilevers of the two hooks 3 are parallel and in opposite directions. The advantage of this arrangement is that when installing, you only need to press down the upper shell 2 and rotate it until the hanging rod 12 corresponds to the hanging groove 31 up and down, loosen the upper shell 2 so that the hanging rod 12 cooperates with the hanging groove 31 to complete the installation, which is convenient for installation and positioning.

[0022] Furthermore, the rod-shaped structure of the hook 3 extends a limiting step 32 in the direction of the cantilever, and the limiting step 32 is located above the hanging groove 31. The purpose of the limiting step 32 is that when the vibration isolation unit is over-pressurized, the limiting step 32 collides with the hanging rod 12 and is limited, thereby preventing the elastic part from being damaged by excessive compression.

[0023] Further, as attached Figure 1 、 4 As shown, the upper shell 2 includes a first shell 21 and a second shell 22, and the second shell 22 is sleeved on the first shell 21. The second shell 22 is made of a thicker metal plate (preferably more than 10 mm), and the first shell 21 is made of a thinner metal sheet (preferably less than 3 mm). Two incisions are respectively provided on both sides of the first shell 21, and a positioning plate 211 is formed between the two incisions. The positioning plate 211 extends a positioning eaves 212 into the first shell 21; the top of the hook 3 is fixedly connected to the mounting block 33, and the mounting block 33 is arranged in the first shell 21 and is clamped by the positioning eaves 212, so that when installing, the positioning plate 211 is bent outward and inserted into the mounting block 33, and then the positioning plate 211 is reset, so that the positioning eaves 212 support the mounting block 33, and then the thicker second shell 22 is covered to seal it. The second shell 22 can be a U-shaped plate, which only covers the positioning plates 211 on both sides. The first shell 21 and the mounting block 33 can be further fixed by bolts.

[0024] Furthermore, the elastic member is a spring 4, one end of the spring 4 abuts against the mounting block 33, and the mounting block 33 is preferably provided with a ring that is sleeved with the end of the spring 4, and the other end of the spring 4 abuts against the base 1, and a sheath 5 is provided on the outside of the spring 4, and the sheath 5 is preferably made of rubber or other soft materials.

[0025] The installation process of the present invention is as follows: put the spring 4 and the sheath 5 into the outer tube 11 of the base 1 in sequence; for the first shell 21, bend the positioning plate 211 outward to insert the mounting block 33 and then reset the positioning plate 211 so that the positioning eaves 212 support the mounting block 33, and then cover the second shell 22. The three can be further fixed by bolts; press the upper shell 2 toward the base 1 and rotate it until the hanging rod 12 and the hanging groove 31 of the hook 3 correspond to each other up and down, loosen the upper shell 2 so that the hanging rod 12 and the hanging groove 31 are matched to complete the installation.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
