[0017] 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.

[0018] Embodiment 1

[0019] See also Figure 1-2 This embodiment provides a technical solution: a bowl-shaped vibration-damping gasket, including a vibration-damping gasket body, and the vibration-damping gasket body material adopts a vibration-suppressing alloy.

[0020] Vibration-suppressing alloy is a damping alloy material that has the same damping properties as rubber while having the strength of structural steel. The principle is that when encountering external force, twins will be generated. As the external force increases, the twins will grow and expand, and new twins will continue to form. The cyclic motion of these twins largely offsets the external force, converting mechanical energy into heat energy to consume energy, thereby achieving the effect of vibration suppression.

[0021] The vibration-damping gasket body is used to connect the control box and the mounting seat. The control box is provided with a lifting ear at the bottom. The bottom of the lifting ear is provided with a bowl-shaped structure. The middle of the bowl-shaped structure is provided with a through hole.

[0022] The vibration-damping gasket body is a centrally symmetrical bowl-shaped structure, which is used to fit with the bottom bowl-shaped structure of the ear, and is composed of a continuous flat portion 1 and a curved portion 2 of the same thickness. The flat portion 1 is provided with a mounting hole 3, which is an annular plane. The curved portion 2 is an arc-shaped structure. The central axes of the flat portion 1, the curved portion 2 and the mounting hole 3 are collinear. A cylinder 4 of uniform thickness is connected to the upper part of the flat portion 1. The size of the inner hole of the cylinder 4 is the same as that of the mounting hole 3. The central axis of the cylinder 4 is collinear with the central axis of the mounting hole 3. The inner hole of the cylinder 4 and the mounting hole 3 are connected as a whole to form a through hole of the vibration-damping gasket body.

[0023] After the flat portion 1 and the curved portion 2 of the vibration-damping gasket body are fitted with the bottom bowl-shaped structure of the lifting ear, the end of the curved portion 2 extends beyond the bottom of the lifting ear for connection with the mounting seat.

[0024] A connecting structure 5 is provided on the outer wall of the cylinder 4. The connecting structure 5 is a threaded connection. The through hole of the lifting ear has an internal thread, and the outer wall of the cylinder 4 has an external thread. After the connection, the upper surface of the cylinder 4 of the vibration damping gasket body is lower than the upper surface of the lifting ear.

[0025] The bolt passes through the through hole of the lifting ear and the through hole of the vibration-damping gasket body to be fixedly connected to the mounting seat, and the control box is fixedly connected to the mounting seat.

[0026] Working principle:

[0027] During installation, the vibration-damping gasket body is fixedly connected to the ear through threads, the flat part 1 and the curved part 2 of the vibration-damping gasket body fit into the bottom bowl-shaped structure of the ear, the end of the curved part 2 extends beyond the bottom of the ear and contacts the mounting seat, the bolts pass through the through holes of the ear and are fixedly connected to the mounting seat through the through holes of the vibration-damping gasket body, and the control box is fixedly connected to the mounting seat.

[0028] When vibration passes through the vibration-damping gasket body from the mounting base, the vibration-damping gasket body is subjected to external force, and twins are generated inside the vibration-damping gasket body. As the external force increases, the twins grow and expand, and new twins are continuously formed. The cyclic motion of these twins offsets the external force and reduces the vibration transmitted from the vibration-damping gasket body to the control box.

[0029] The vibration-damping gasket body is made of a vibration-damping alloy and has a vibration-damping effect. It is equipped with a flat portion 1 and a curved portion 2 to fit with the lifting ear, and can simultaneously meet the requirements of fixing the control box and the mounting seat, spacing the control box and the mounting seat, and reducing the vibration transmitted to the control box through the lifting ear and the mounting seat. A connecting structure 5 is provided on the outer wall of the cylinder 4 and is fixedly connected to the lifting ear, which further strengthens the fixation of the vibration-damping gasket and the control box and increases the anti-loosening effect.

[0030] Embodiment 2

[0031] The bowl-shaped vibration-damping gasket of the utility model is different from the first embodiment in that the connection structure 5 is a bayonet connection, the through hole of the lifting ear has a bayonet 1, and the outer wall of the cylinder 4 is provided with a bayonet 2.

[0032] Embodiment 3

[0033] The bowl-shaped vibration-damping gasket of the utility model is different from the first embodiment in that the connection structure 5 is a key connection, and the through hole of the ear and the outer wall of the cylinder 4 are respectively provided with a key and a key groove.

[0034] The connection structure 5 used in the present invention may also be other connection structures in which the vibration-damping gasket body and the lifting ear can be connected to each other in a cooperative manner, such as a tight fit.

[0035] 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.
