Description

Technical Field

[0001] This utility model relates to the field of U-bolt technology, and in particular to a U-bolt for automotive gearboxes. Background Technology

[0002] A U-bolt is a metal fastener named for its U-shaped appearance. It primarily consists of a U-shaped main body and threaded straight sections at both ends. The U-shaped section encircles the object being secured, such as a car gearbox, pipe, or other equipment components. The threaded straight sections at both ends are used to install nuts. By tightening the nuts, the U-shaped section grips the object, thus achieving the purpose of fastening.

[0003] When installing U-bolts, first place the U-bolt on the corresponding position of the car gearbox, then attach another set of cross plates to the U-bolt, and finally tighten the corresponding nuts to achieve a fixing effect.

[0004] When installing U-bolts, the cross plate and its corresponding nut are separate parts. When multiple models of U-bolts are placed together, if the corresponding model of U-bolt needs to be selected for fixing, the cross plate and nut need to be carefully identified and matched among many parts. This process is not only time-consuming and laborious, but also prone to errors due to carelessness, which can affect the accuracy of installation and the tightening effect. This may lead to the need to reselect the corresponding cross plate and nut. Furthermore, since the cross plate, nut and bolt body are separate, parts are prone to being mixed up or lost during storage. Once the critical cross plate or nut is missing, the entire U-bolt set cannot be used normally, delaying the installation progress and increasing the additional cost of repurchasing or finding suitable parts. Therefore, a U-bolt for automotive gearboxes is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a U-bolt for automotive gearboxes, which aims to improve the problem that existing multi-component U-bolts are mixed together, making them inconvenient to handle and easy to lose.

[0018] As a further description of the above technical solution:

[0019] The rear end of the support block is fixedly connected to the front end of the connecting plate.

[0020] As a further description of the above technical solution:

[0021] One end of the connecting spring is fixedly connected to the outer wall of the fixing pin, and the other end of the connecting spring is fixedly connected to the inner wall of the support block. The outer wall of the fixing pin passes through and is slidably connected to the inner wall of the support block, and the side of the fixing pin near the bolt is inserted into the inner wall of the bolt.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of a U-bolt for automotive gearboxes, comprising a U-bolt 1, with a connecting mechanism provided on the outer arc surface of the right side of the U-bolt 1. The connecting mechanism prevents the cross plate on the U-bolt 1 from being lost. The U-bolt 1 is used for connecting and fixing the automotive gearbox. The connecting mechanism includes a telescopic tube 2, with a fixing ring 9 fixedly connected to the left end of the telescopic tube 2. The overall length of the telescopic tube 2 is adjustable, facilitating the installation and fixing of the U-bolt 1. The fixing ring 9 is a semi-ring, with a connecting ring 7 rotatably connected to the left end of the fixing ring 9, and a fixed connection to the right end of the connecting ring 7. There is a connecting plate 5, and the connecting ring 7 is set as a semi-ring and is consistent with the movement trajectory of the connecting plate 5. The connecting plate 5 is in contact with the left end of the telescopic tube 2. The inner wall of the connecting plate 5 is provided with fasteners, which can be used to install and fix the U-bolt 1. The inner wall of the right side of the telescopic tube 2 is threaded with a screw 4. The front end of the right side of the U-bolt 1 has multiple sets of connecting holes, which can be connected and fixed with the screw 4, and the screw 4 can remain in the telescopic tube 2. The front end of the connecting plate 5 is provided with a reinforcing mechanism, which can enhance the stability of the U-bolt 1 after installation and fixation. There are two sets of reinforcing mechanisms.

[0033] Reference Figures 1-3 The inner sidewall of the telescopic tube 2 is rotatably and slidably connected to the outer right arc surface of the U-bolt 1. The right end of the telescopic tube 2 is set as a ring, which allows for corresponding rotation and sliding. The rotation setting facilitates the installation and fixing of the U-bolt 1, and the sliding is up and down, thereby enabling the connection and fixing of different models of car gearboxes. The fasteners include bolts 6, the outer wall of bolts 6 is threaded to the inner wall of the connecting plate 5, and bolts 6 can also remain inside the connecting plate 5. The rear end of bolts 6 is threaded to the inner wall of the left front end of the telescopic tube 2, and a screw hole is opened at the left front end of the telescopic tube 2. This allows for a threaded connection with bolt 6 to achieve a fixing effect. The inner sidewalls of connecting ring 7 and fixing ring 9 contact the top left side of U-bolt 1, and this contact setting achieves a pre-positioning effect. After pre-positioning, it can be determined whether the telescopic tube 2 needs to move up and down. The rear end of screw 4 is threadedly connected to the inner wall of the front right side of U-bolt 1. Screw 4 is threadedly connected to the connecting hole, thereby limiting and fixing the right end of telescopic tube 2. A baffle 3 is fixedly connected to the top right side of U-bolt 1. The baffle 3 prevents telescopic tube 2 from detaching from U-bolt 1.

[0034] Reference Figures 3-4The reinforcing mechanism includes a support block 10. The inner wall of the support block 10 is elastically connected to a fixing pin 11 via a connecting spring 8. The fixing pin 11 serves as a limiting connection, thereby enhancing the overall stability of the U-bolt 1. The rear end of the support block 10 is fixedly connected to the front end of the connecting plate 5, and the support block 10 serves to connect and fix the connecting plate 5. One end of the connecting spring 8 is fixedly connected to the outer wall of the fixing pin 11, and the other end of the connecting spring 8 is fixedly connected to the inner wall of the support block 10. The outer wall of the fixing pin 11 is slidably connected to the inner wall of the support block 10. The through-hole setting of the fixing pin 11 allows for easy manual movement of the fixing pin 11, thereby releasing the corresponding limiting. The side of the fixing pin 11 near the bolt 6 is inserted into the inner wall of the bolt 6. The insertion of the two reduces the vibration that affects the stability of the bolt 6 when the car and its gearbox are working.

[0035] Working Principle: When installing a car transmission, first, the semi-ring structure composed of connecting ring 7 and fixing ring 9 is placed on the top left side of U-bolt 1. Then, connecting ring 7 is rotated to close and form a ring with fixing ring 9, achieving initial positioning (connecting ring 7 and fixing ring 9 are initially in an open state). The rotating and sliding connection structure between the inner side wall of telescopic tube 2 and the outer arc surface of the right side allows it to slide up and down within a certain range to adapt to transmission connection points with different heights or installation positions. After telescopic tube 2 is adjusted to the appropriate position, screw 4 is passed through the inner right side wall of telescopic tube 2 and screwed into the connecting hole at the front right side of U-bolt 1 to limit and fix the right end of telescopic tube 2, preventing it from moving freely and ensuring its stability during installation. After ensuring the accurate positioning of the telescopic tube 2, further tightening is performed using the bolts 6 on the inner wall of the connecting plate 5. The bolts 6 are passed through the connecting plate 5 and screwed into the screw holes on the inner wall of the left front end of the telescopic tube 2. As the bolts 6 are tightened, the connecting plate 5 and the telescopic tube 2 are tightly connected together. At the same time, due to the contact and cooperation between the connecting ring 7 and the fixing ring 9 and the U-bolt 1, the entire connection mechanism is firmly fixed on the U-bolt 1, thereby stably installing the U-bolt 1 between the gearbox and the frame, achieving reliable fixation of the gearbox. After fixing, the two sets of fixing pins 11 are inserted and limited to the bolts 6 to enhance the stability of the bolts 6 and ensure that they will not be displaced or loosened due to external forces such as vibration and bumps during vehicle operation.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
