Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to a locking bolt. Background Technology

[0002] Bolts, as a common fastener, are widely used in various mechanical devices and building structures. They are typically made of metal, have a cylindrical shape, are threaded at one end, and have a corresponding nut at the other. By rotating the nut, the bolt can tightly connect two or more components together, ensuring the stability and safety of the structure. There are many types of bolts, including but not limited to hex bolts, socket head cap screws, and countersunk head bolts, each with its specific application scenarios and functional characteristics. Whether in large-scale engineering projects or in small-scale maintenance in daily life, bolts play an indispensable and important role.

[0003] In the current assembly process, bolts are commonly used as the primary means of fixing components. While this method can ensure the stability of components to a certain extent, bolt fixing requires a certain amount of space and creates a relatively complex structure at the connection point, making it quite difficult to operate when precise positioning of the component is required. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a locking bolt, which aims to improve the problem that existing components are usually fixed with bolts, which makes it inconvenient to position the lower component at the component connection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stop bolt, comprising a bolt body and an internal hexagonal head fixedly installed on the top of the bolt body for controlling the bolt body; a stop mechanism installed inside the internal hexagonal head for preventing the lower component from rotating; the stop mechanism includes a compression spring, a stop post, and a limiting block, the stop post being slidably connected inside the bolt body, the stop post being installed at the bottom of the limiting block, the limiting block being slidably connected inside the bolt body, a fixing block being fixedly connected inside the internal hexagonal head, a compression spring being provided between the fixing block and the limiting block, a second limiting groove being formed inside the limiting block, one side of the compression spring being inserted into the second limiting groove, a first limiting groove being formed inside the fixing block, and the other side of the compression spring being inserted into the first limiting groove; a replacement mechanism installed inside the limiting block for replacing the stop post after wear.

[0006] Furthermore, the limiting block cannot slide out from inside the internal hexagon head, which is used to prevent the stop post from slipping out from inside the internal hexagon head.

[0007] Furthermore, the limiting groove is used to limit the force offset between the compression spring and the fixed block.

[0008] Furthermore, the second limiting groove is used to limit the force offset between the compression spring and the second limiting groove.

[0009] Furthermore, the replacement mechanism includes a plug, and the limiting block has a slot inside, so that the plug can be inserted into the slot.

[0010] Furthermore, a slider is fixedly connected to the outer wall of the slot, and a slot is formed on the outer wall of the slider.

[0011] Furthermore, the limiting block has a second sliding groove inside, and the slider can slide inside the second sliding groove.

[0012] Furthermore, the limiting block has a groove inside, and the slider can slide inside the groove.

[0013] Furthermore, the limiting block has a bowl-shaped groove inside, and a retaining ball is installed inside the limiting block. The retaining ball is slidably connected inside the bowl-shaped groove and can be engaged inside the groove.

[0014] Furthermore, a limiting post is fixedly connected to the outer wall of the ball, the limiting post is slidably connected inside the limiting block, and a reset spring is sleeved on the outer wall of the limiting post.

[0015] This utility model has the following beneficial effects: 1. In this utility model, the bolt body is first fixed in the component to be installed by controlling the internal hex head, and then the stop post can be inserted into the lower component by the action of the compression spring, thereby preventing the lower component from rotating. This solves the problem of inconvenience in positioning the lower component at the component connection and improves the applicability of the bolt.

[0016] 2. In this utility model, the slider can slide into the limiting block along the second slide groove by the cooperation of the slider, and the slider can slide into the first slide groove by the rotation of the stop post. The slider can then be fixed by the ball in the first slide groove in conjunction with the force of the reset spring, thereby installing the stop post at the bottom of the limiting block. This makes it easier to replace the stop post after it wears out, thus improving the service life of the stop bolt. Attached Figure Description

[0019] 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.

[0020] Reference Figure 1 - Figure 4 The present invention provides an embodiment of a stop bolt, comprising a bolt body 2, an internal hexagon head 1, fixedly installed on the top of the internal hexagon head 1 for controlling the bolt body 2; a stop mechanism, installed inside the internal hexagon head 1, for preventing the lower part from rotating; the stop mechanism includes a compression spring 6, a stop post 3 and a limit block 7, the stop post 3 is slidably connected inside the bolt body 2, the stop post 3 is installed at the bottom of the limit block 7, the limit block 7 is slidably connected inside the bolt body 2, a fixing block 4 is fixedly connected inside the internal hexagon head 1, a compression spring 6 is provided between the fixing block 4 and the limit block 7, a second limit groove 9 is opened inside the limit block 7, one side of the compression spring 6 is inserted into the second limit groove 9, a first limit groove 5 is opened inside the fixing block 4, the other side of the compression spring 6 is inserted into the first limit groove 5; The replacement mechanism is installed inside the limit block 7 and is used to replace the stop post 3 after it is worn. Specifically, in actual use, the operator can precisely control the bolt body 2 through the internal hex head 1, enabling it to rotate and lock onto the installed component. Simultaneously, under the elastic force generated by the compression spring 6, the stop post 3 will be subjected to the force applied by the compression spring 6, thus inserting into the corresponding position of the lower component, preventing the lower component from rotating. The stop post 3 is securely installed in the internal structure of the internal hex head 1 through the limiting block 7. This design not only ensures that the stop post 3 slides inside the bolt body 2, but also effectively prevents the stop post 3 from accidentally slipping out of the bolt body 2. To further ensure the stability of the structure, a limiting groove 2 9 is specially provided on the limiting block 7, and a limiting groove 1 5 is also provided on the fixing block 4. Through the cooperation of these two limiting grooves, the direction of the force of the compression spring 6 can be limited, thereby preventing the force between the compression spring 6 and the fixing block 4, and between the compression spring 6 and the limiting groove 2 9 from shifting.

[0021] Considering the potential wear and tear on the stop post 3 during prolonged use, the designers have provided a convenient disassembly solution. The stop post 3 can be easily removed from the bottom of the limit block 7. To reinstall the stop post 3, the operator simply inserts the top pin 10 of the stop post 3 into the pre-drilled slot 8 in the limit block 7. At this point, the slider 13 will smoothly slide along the second groove 12 on the inner wall of the slot 8. Once the pin 10 is fully inserted into the slot 8, the operator can gently rotate the stop post 3, causing the slider 13 on the outer wall of the pin 10 to continue sliding along the first groove 11 on the inner wall of the slot 8. When the slider 13 reaches the inner side of the first groove 11, the retaining ball 15 inside the limit block 7, under the force of the return spring 16, inserts into the retaining groove 14 on the outer wall of the slider 13, thus achieving a secure fixation between the stop post 3 and the limit block 7, ensuring the stability and reliability of the entire stop bolt system.

[0022] Working principle: When this locking bolt is in use, the internal hex head 1 controls the bolt body 2 to rotate and lock onto the installed part. Under the action of the compression spring 6, the locking post 3 will be inserted into the lower part by the force of the compression spring 6, thus preventing the lower part from rotating. The locking post 3 is installed inside the internal hex head 1 through the limiting block 7, which allows the locking post 3 to slide inside the bolt body 2 while preventing the locking post 3 from slipping out of the bolt body 2. The limiting block 7 is provided with a second limiting groove 9, and the fixing block 4 is also provided with a first limiting groove 5. The first limiting groove 5 and the second limiting groove 9 can limit the direction of the force of the compression spring 6, thereby preventing the compression spring 6 from interfering with the fixing block 4 and the second limiting groove 9. To prevent wear of the stop post 3 during prolonged use, the stop post 3 can be removed from the bottom of the limit block 7. When the stop post 3 is installed at the bottom of the limit block 7, the insert post 10 at the top of the stop post 3 can be inserted into the slot 8 opened in the limit block 7. The slider 13 will slide along the second slide groove 12 opened in the inner wall of the slot 8. After the insert post 10 is fully inserted into the slot 8, the stop post 3 can be rotated so that the slider 13 on the outer wall of the insert post 10 slides along the first slide groove 11 opened in the inner wall of the slot 8. After sliding to the inner side of the first slide groove 11, the retaining ball 15 inside the limit block 7 will be inserted into the retaining groove 14 opened in the outer wall of the slider 13 by the force of the return spring 16, thereby fixing the stop post 3 and the limit block 7.

[0023] 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.
