DETAILED DESCRIPTION

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other. The technical solution of the present invention will be further described below in conjunction with the drawings of the embodiments of the present invention, and the present invention is not limited to the following specific implementation methods.

[0020] It should be understood that the same or similar numbers in the drawings of the embodiments correspond to the same or similar parts. In the description of the present utility model, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom" and the like indicating the orientation or positional relationship, they are based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0021] In one embodiment, Figure 1-5 As shown, a reinforcing bolt for automobiles comprises a bolt body 1, a nut 2 is threadedly sleeved on the upper end of the surface of the bolt body 1, four fixing plates 3 are fixedly connected to the upper end surface of the bolt body 1, the four fixing plates 3 are arranged in a circular array about the center of the upper end surface of the bolt body 1, a support block 4 is fixedly connected to the center of the upper end surface of the bolt body 1, a round ball 5 is placed between the four fixing plates 3, the bottom of the round ball 5 is placed on the top surface of the support block 4, slots 6 are provided on the facing surfaces of the four fixing plates 3 and near the bottom, a fixing assembly 7 is arranged between the four fixing plates 3, a fixing sleeve 8 is movably sleeved on the lower ends of the outer surfaces of the four fixing plates 3, and a plurality of gaskets 9 are movably sleeved on the upper end of the surface of the bolt body 1.

[0022] In order to be able to press down the ball 5 and prevent the ball 5 from moving out from between the four fixing plates 3, the fixing assembly 7 includes a fixing block 71, and the front, back, left and right sides of the fixing block 71 are respectively facing the four fixing plates 3, and the front, back, left and right sides of the fixing block 71 are movably sleeved with fixing rods 72, and the ends of the four fixing rods 72 away from the fixing block 71 are respectively inserted into adjacent slots 6, and the top surface and the bottom surface of the inner wall of the fixing block 71 are fixedly connected with a connecting block 73 in the middle, and the front, back, left and right sides of the connecting block 73 are fixedly connected with springs 74, and one end of the four springs 74 is respectively fixedly connected to the side of the four fixing rods 72 close to the connecting block 73.

[0023] In order to facilitate the movement of the fixing rod 72 toward the inside of the fixing block 71, a push rod 75 is fixedly connected to the top surface of each fixing rod 72 and the side close to the fixing plate 3, and a limiting plate 76 is fixedly connected to the top surface of each fixing rod 72 and the side away from the fixing plate 3. The limiting plate 76 is in contact with the side surface of the inner wall of the fixing block 71, and the limiting plate 76 can prevent the spring 74 from completely pushing the fixing rod 72 out of the fixing block 71.

[0024] In order to enable the nut 2 to be compressed and fixed when it is at different positions on the bolt body 1, a number of gaskets 9 are stacked up and down and sleeved on the upper end of the surface of the bolt body 1, the top surface of the uppermost gasket 9 is fixedly connected to the bottom surface of the fixing sleeve 8, and the bottom surface of the lowermost gasket 9 is fixedly connected to the top surface of the nut 2. The position of the fixing sleeve 8 on the fixing plate 3 is fixed. When the nut 2 is located at different positions on the bolt body 1, the fixing sleeve 8 can compress and fix the nut 2 by adding or removing gaskets 9.

[0025] In order to facilitate the removal of the ball 5 from between the four fixing plates 3, a pulling block 51 is fixedly connected to the front and rear sides of the ball 5 and near the top, and a plug hole 52 is opened in the middle of the pulling block 51 in the left and right directions. The fixing plate 3 is elastic, so the fixing plate 3 has a certain clamping effect on the ball 5, and it cannot be automatically removed from between the four fixing plates 3, and it is not convenient to move the ball 5 with tools. The ball 5 can be pulled out by using a rod to move the pulling block 51.

[0026] In order to make the fixing plate 3 have a certain elasticity, the material of the fixing plate 3 is ABS plastic, and the outer surfaces of the four fixing plates 3 are coated with an anti-oxidation coating. By coating the fixing plate 3, the anti-oxidation effect of the fixing plate 3 can be increased, thereby improving the service life of the fixing plate 3.

[0027] Working principle: When the utility model is used, the nut 2, the gasket 9 and the fixing sleeve 8 are sequentially sleeved on the upper end of the bolt body 1, and then the ball 5 is placed between the four fixing plates 3 and pressed downward so that the bottom of the ball 5 abuts against the top surface of the support block 4, and then the push rod 75 is moved to make the four fixing rods 72 move toward the inner cavity of the fixing block 71, and then the fixing block 71 is placed between the four fixing plates 3, so that the bottom surface of the fixing block 71 abuts against the top surface of the ball 5, and the four fixing rods 72 are respectively aligned with the slots 6 on the four fixing plates 3, and then the pushed push rod 75 is released, and the spring 74 will push the fixing rod 72 outward, so that the four fixing rods 72 are respectively inserted into the corresponding slots 6, and the fixing block 71 is fixed, so that the fixing block 71 fixes the ball 5 to prevent the ball 5 from moving out from between the four fixing plates 3 due to vibration, and the ball 5 will squeeze the upper ends of the four fixing plates 3 , since the fixing plate 3 has a certain elasticity, the upper ends of the four fixing plates 3 will expand outward, increasing the distance between the upper ends of the four fixing plates 3, so that the distance outside the four fixing plates 3 exceeds the diameter of the inner cavity of the fixing sleeve 8, so that the fixing sleeve 8 cannot move upward, the fixing sleeve 8 presses the gasket 9, and the gasket 9 presses the nut 2, so that the nut 2 cannot move upward, effectively preventing the nut 2 from loosening and retreating, and improving the stability of the connection between the bolt body 1 and the nut 2. When it is necessary to remove the nut 2, first, the push rod 75 is pushed to pull the fixing rod 72 out of the slot 6 on the fixing plate 3, and then the fixing block 71 is removed from between the four fixing plates 3 to limit the upward movement of the ball 3, and then the rod is used to insert it into the socket 52 on the pull-out block 51, and then the rod can be pulled up to remove the ball 5 from between the four fixing plates 3, so that it is more convenient to remove the ball 5.

[0028] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
