Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamping fixture for locking nuts. Background Technology

[0002] A clamp for locking nuts generally refers to a special tool or device used to hold and fix a specific type of locking nut to prevent it from rotating or slipping when tightening the head of a bolt or screw.

[0003] Currently, when using clamps, the spacing between clamps is usually adjusted by sliding, which results in uneven clamping force. This makes the clamps prone to sliding and expanding outward when clamping the locking nut, thus reducing the clamping force.

[0004] Meanwhile, when using the locking nut, the operator usually needs to manually adjust the position of the clamp and align the bolt, which makes the nut inconvenient to tighten and prone to falling off.

[0005] Therefore, we propose a clamp for locking nuts to solve the problems mentioned above. Utility Model Content

[0006] This utility model proposes a clamp for locking nuts to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: including a clamping base, an anti-expansion mechanism, and a positioning mechanism. The anti-expansion mechanism includes a vertical plate and a counterweight. The vertical plate is attached to the upper surface of the clamping base. The vertical plate and the counterweight are used to increase the clamping weight of the device and prevent outward expansion during the clamping process.

[0008] The positioning mechanism includes a positioning cover and a magnet. The magnet is connected to the inner wall of the positioning cover. The positioning cover and the magnet are used for locking the nut for positioning, eliminating the need to constantly adjust the position of the clamp.

[0009] Preferably, the anti-outward expansion mechanism further includes a sliding rod, which is fixedly connected to the side surface of the upright plate, and is sleeved with a counterweight. The outer surface of the sliding rod is provided with a friction strip, and a stop block is fixedly connected to the right end of the sliding rod.

[0010] Preferably, the positioning mechanism further includes a spring, the top end of which is fixedly connected to the lower surface of the clamp seat, the bottom end of which is fixedly connected to the upper surface of the positioning cover, a ball is movably connected inside the positioning cover, a rubber rod is fixedly connected to the upper surface of the ball, a connecting rod is provided at the top end of the rubber rod, and the top end of the connecting rod is fixedly connected to the lower surface of the clamp seat.

[0011] Preferably, the inner wall of the positioning cover is provided with a rubber seat, and the rubber seat is located outside the magnet.

[0012] Preferably, the upper surface of the clamp seat is provided with a sliding groove, a slider is slidably connected inside the sliding groove, a clamping ring is fixedly connected to the upper surface of the slider, and a threaded block is provided on the side surface of the clamping ring.

[0013] Preferably, a connecting plate is fixedly connected to the side surface of the clamping ring, and the side surface of the connecting plate is fixedly connected to the side surface of the upright plate, wherein the upright plate is located in front of and behind the slide groove.

[0014] Preferably, the fixture seat has an internal threaded connection to a threaded rod, and the left end of the threaded rod is in contact with the side surface of the slider, and the threaded rod is located inside the slide groove.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. In this utility model, during the movement of the clamping ring, the upright plate can move on the surface of the clamping seat to support the clamping ring. By utilizing the sliding connection between the counterweight and the slide rod, the distance between the counterweight and the clamping ring can be adjusted. The friction strip can increase the friction between the counterweight and the slide rod, making it difficult for the counterweight to move on the surface of the slide rod. Through the support of the upright plate and the weight of the counterweight, the weight and support range of the clamping ring can be increased, preventing the clamping ring from expanding outward when clamping the locking nut.

[0020] 2. In this utility model, a round hole is used to allow one end of the bolt to penetrate the interior of the clamp seat and extend into the positioning cover. A magnet is used to attract and fix the bolt extending into the positioning cover. The rubber seat can be pressed against the surface of the bolt, thereby positioning the locking nut and the clamp. When the locking nut is tightened, the bolt can rotate inside the positioning cover with the magnet as the center. By tightening the locking nut, the bolt can push the positioning cover and stretch the spring and rubber rod, so that the nut is not easy to fall off during the tightening process.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1, as shown in the attached document Figures 1-4 As shown, it includes a clamp base 1, an anti-expansion mechanism 4, and a positioning mechanism 9. The anti-expansion mechanism 4 includes a vertical plate 401 and a counterweight 405. The vertical plate 401 is attached to the upper surface of the clamp base 1. The vertical plate 401 and the counterweight 405 are used to increase the clamping weight of the device and prevent outward expansion during the clamping process.

[0030] The positioning mechanism 9 includes a positioning cover 901 and a magnet 905. The magnet 905 is connected to the inner wall of the positioning cover 901. The positioning cover 901 and the magnet 905 are used for locking the nut for positioning, eliminating the need to constantly adjust the position of the clamp.

[0031] The overall effect of Embodiment 1 is as follows: the upright plate 401 can support the clamping ring 3, and the counterweight 405 can increase the weight of the upright plate 401 and the clamping ring 3, so that the clamping ring 3 is less likely to expand outward when clamping the locking nut. At the same time, the positioning cover 901 and the magnet 905 can be used to extend the threaded rod 5 into the interior of the positioning cover 901 and attract the magnet 905 to position the device, thereby improving the convenience of using the device.

[0032] Example 2, as Figures 1-3 As shown, the anti-expansion mechanism 4 also includes a slide rod 404, which is fixedly connected to the side surface of the upright plate 401. The slide rod 404 is sleeved and connected to the counterweight 405. A friction strip 402 is provided on the outer surface of the slide rod 404. A stop block 403 is fixedly connected to the right end of the slide rod 404. A connecting plate 2 is fixedly connected to the side surface of the clamping ring 3, and the side surface of the connecting plate 2 is fixedly connected to the side surface of the upright plate 401. The upright plate 401 is located in front of and behind the slide groove 8.

[0033] The overall effect of embodiment 2 is as follows: when the clamping ring 3 clamps the locking nut, the vertical plate 401 is in contact with the upper surface of the clamping seat 1, so that the clamping ring 3 can move the vertical plate 401 on the surface of the clamping seat 1 to support the clamping ring 3 during the movement. The sliding connection between the counterweight 405 and the slide rod 404 can adjust the distance between the counterweight 405 and the clamping ring 3. The friction strip 402 can increase the friction between the counterweight 405 and the slide rod 404, making it difficult for the counterweight 405 to move on the surface of the slide rod 404. Through the support of the vertical plate 401 and the weight of the counterweight 405, the weight and support range of the clamping ring 3 can be increased, preventing the clamping ring 3 from expanding outward when clamping the locking nut.

[0034] Example 3, as Figure 2 , Figure 4 and Figure 5 As shown, the positioning mechanism 9 also includes a spring 904. The top end of the spring 904 is fixedly connected to the lower surface of the clamp seat 1, and the bottom end of the spring 904 is fixedly connected to the upper surface of the positioning cover 901. A ball 906 is movably connected inside the positioning cover 901. A rubber rod 902 is fixedly connected to the upper surface of the ball 906. A connecting rod 903 is provided at the top end of the rubber rod 902, and the top end of the connecting rod 903 is fixedly connected to the lower surface of the clamp seat 1. A rubber seat 14 is provided on the inner wall of the positioning cover 901, and the rubber seat 14 is located outside the magnet 905.

[0035] The effect achieved by the entire embodiment 3 is as follows: when the locking nut is clamped, the bolt can be extended into the positioning cover 901 through the round hole. The bolt extended into the positioning cover 901 can be attracted and fixed by the magnet 905. The rubber seat 14 can be pressed against the surface of the bolt, thereby positioning the locking nut and the clamp. When the locking nut is tightened, the bolt can rotate inside the positioning cover 901 with the magnet 905 as the center. By tightening the locking nut, the bolt can push the positioning cover 901 and stretch the spring 904 and the rubber rod 902, so that the device is not easy to fall off during the locking process.

[0036] Example 4, as Figures 1-3 As shown, the upper surface of the clamping base 1 is provided with a sliding groove 8, and a slider 13 is slidably connected inside the sliding groove 8. A clamping ring 3 is fixedly connected to the upper surface of the slider 13. A threaded block 12 is provided on the side surface of the clamping ring 3. A threaded rod 5 is threadedly connected inside the clamping base 1, and the left end of the threaded rod 5 is in contact with the side surface of the slider 13. The threaded rod 5 is located inside the sliding groove 8. A handle 10 is fixedly connected to the lower surface of the clamping base 1, and the handle 10 is located on both sides of the positioning cover 901. A fixing seat 11 is fixedly connected to the lower surface of the clamping base 1. A throttle 7 is fixedly connected to the side surface of the fixing seat 11. A grip block 6 is fixedly connected to the right end of the throttle 7. A round hole is provided inside the clamping base 1, and the round hole is located between the clamping rings 3 and corresponds to the positioning cover 901.

[0037] The overall effect of embodiment 4 is as follows: by sliding the groove 8 and the slider 13, the distance between the clamping rings 3 can be adjusted. When the clamping ring 3 is in contact with the surface of the locking nut, turning the threaded rod 5 can continuously extend into the interior of the groove 8 to squeeze the slider 13, so that the clamping ring 3 can clamp and fix the locking nut. The threaded block 12 can increase the friction between the clamping ring 3 and the locking nut, so that it is not easy to slip during the locking process. After the clamping ring 3 has clamped the locking nut, the grip block 6 can be held so that the clamping seat 1 can be rotated by the rotating rod to complete the locking installation of the nut.

[0038] The working principle of the entire device is as follows: the sliding of the slide groove 8 and the slider 13 allows for adjustment of the distance between the clamping rings 3. When the clamping ring 3 is in contact with the surface of the locking nut, turning the threaded rod 5 can continuously extend into the interior of the slide groove 8 to squeeze the slider 13, so that the clamping ring 3 can clamp and fix the locking nut. Since the vertical plate 401 is in contact with the upper surface of the fixture seat 1, the clamping ring 3 can move the vertical plate 401 on the surface of the fixture seat 1 during movement to support the clamping ring 3. The sliding connection between the counterweight 405 and the slide rod 404 allows for adjustment of the distance between the counterweight 405 and the clamping ring 3. Through the support of the vertical plate 401 and the weight of the counterweight 405, the weight and support range of the clamping ring 3 can be increased. The friction strip 402 can increase the friction between the counterweight 405 and the slide rod 404, making it difficult for the counterweight 405 to move on the surface of the slide rod 404.

[0039] The bolt is inserted through a round hole into the positioning cover 901. The bolt is attracted and fixed inside the positioning cover 901 by a magnet 905. The rubber seat 14 is pressed against the surface of the bolt to position the locking nut and the clamp. The grip 6 is held so that the clamp seat 1 can be rotated by the rotating rod. When the locking nut is tightened, the bolt can rotate inside the positioning cover 901 with the magnet 905 as the center. The tightening of the locking nut pushes the positioning cover 901 and stretches the spring 904 and the rubber rod 902 to complete the locking installation of the nut.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
