[0020] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.

[0021] As Figure 1 , Figure 2 shown, the present utility model provides a waterproof cable joint fixing device, including a base mechanism 1. A connection mechanism 2 is arranged on the front side of the base mechanism 1. A locking mechanism 3 is arranged on the front side of the connection mechanism 2. Extended installation bolts 4 are arranged on both the upper and lower sides of the locking mechanism 3. The locking mechanism 3 includes a first arc-shaped clamping block 31 and a second arc-shaped clamping block 32. The opposite surfaces of the first arc-shaped clamping block 31 and the second arc-shaped clamping block 32 are chamfered to prevent damage to the cable after locking, protect the cable, and cancel the toothed structure, improve the cable fitting degree, enhance the sealing effect, and protect the cable surface. Bolt holes 33 penetrating through left and right are opened at both the upper and lower ends on the left side of the second arc-shaped clamping block 32. Nut grooves 35 penetrating through left and right are opened at both the upper and lower ends on the right side of the first arc-shaped clamping block 31. Stainless steel nuts 34 are fixedly installed on the inner circles of the two nut grooves 35. Changing the traditional tapping to embedding 304 stainless steel nuts 34 can prevent the thread from slipping and ensure the vertical spiral fit of the bolt and the nut, improve the pulling force and the wire fixing strength;

[0022] By opening the nut grooves 35, the installation space for spare nuts is increased. Spare nuts can be used in case of emergency for emergency treatment. Using the extended installation bolts 4, the first arc-shaped clamping block 31 and the second arc-shaped clamping block 32 can easily pass through the cable with the maximum wire diameter specified by the device after connection, improve the single-person operability, make the installation more convenient, and improve the production efficiency.

[0023] As Figure 3 shown, the connection mechanism 2 includes a connection ring 21. A number of connection bolt grooves 22 penetrating through front and back are arranged in an annular array on the connection ring 21. Extension plates 23 are fixedly installed on both the upper and lower sides at the front end of the connection ring 21. Bolt through holes 24 penetrating through left and right are opened on both extension plates 23. The two extended installation bolts 4 respectively penetrate through the stainless steel nuts 34, the bolt through holes 24, and the bolt holes 33 to the left side of the second arc-shaped clamping block 32;

[0024] By reducing the size of the overall connection ring 21, the product is miniaturized, unnecessary designs are avoided, thus reducing the occupied space and making it more convenient for installation and matching the miniaturization of the customer device. Through the bolt through holes 24 opened in the extension block, the pulling force of the lengthened installation bolt 4 on the first arc-shaped clamping block 31 and the second arc-shaped clamping block 32 is increased, protecting the cable, improving the cable contact, and reducing the shaking after the cable is locked.

[0025] As Figure 4 shown, the base mechanism 1 includes a base plate 11. The base plate 11 is annularly and arrayedly provided with a plurality of butt joint bolt holes 12 that penetrate through from front to back. The plurality of butt joint bolt holes 12 are respectively aligned with a plurality of connecting bolt grooves 22 from front to back. Thus, a plurality of bolts can be used to pass through the butt joint bolt holes 12 and the connecting bolt grooves 22 to fix the connection ring 21 on the front side of the base plate 11. A rubber sleeve 13 is fixedly connected to the center of the front side of the base plate 11, and a funnel-shaped rubber sleeve 15 is fixedly connected to the rear side of the base plate 11. The inner cavities of the rubber sleeve 13 and the funnel-shaped rubber sleeve 15 penetrate through from front to back. A plurality of first reinforcing ribs 14 are uniformly fixedly installed on the inner ring of the rubber sleeve 13 to improve the strength of the rubber ring, increase the friction force between the cable and the inner wall of the rubber sleeve 13, and improve the sealing effect. A second reinforcing rib 16 is fixedly installed on the rear side of the funnel-shaped rubber sleeve 15, and the second reinforcing rib 16 extends in an arc shape inward, which can enhance the cable sealing and enhance the followability of the cable at different angles.

[0026] Next, the working principle of the waterproof cable joint fixing device will be specifically described.

[0027] As Figures 1-4 shown, during installation, the cable is passed through the rubber sleeve 13 on the front side of the base plate 11. The plurality of first reinforcing ribs 14 on the inner ring of the rubber sleeve 13 are used to improve the sealing performance between the rubber sleeve 13 and the cable. At the same time, the second reinforcing rib 16 at the rear end of the funnel-shaped rubber sleeve 15 is used to improve the sealing performance and enhance the followability of the cable at different angles. Moreover, by using the connection ring 21 that is fixed to the front side of the base plate 11 through bolts after the butt joint bolt holes 12 and the connecting bolt grooves 22 are aligned in advance, as well as the first arc-shaped clamping block 31 and the second arc-shaped clamping block 32, the two bolt holes 33 and the bolt through holes 24, and the two stainless steel nuts 34 and the bolt through holes 24 are all aligned left and right. Then, the lengthened installation bolt 4 is passed through the stainless steel nut 34 and rotated until it passes through the bolt through hole 24 and then through the bolt hole 33, so that the first arc-shaped clamping block 31 and the second arc-shaped clamping block 32 approach each other to clamp the left and right sides of the rubber sleeve 13, thereby improving the stability between the cable and the rubber sleeve 13.

[0028] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are within the protection scope of the present utility model.
