However, the larger main cavity will cause the staff to rotate the shooting gun operating rod many times before the sling screw rod can push the locking block to cooperate with the main cavity to press the main cable, so as to complete the stable connection between the wire clip and the main cable, thus reducing the installation efficiency of the wire clip by the staff to a certain extent. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that in the prior art, the larger main cavity causes the staff to rotate the shooting gun operating rod many times to complete the connection between the main cable and the wire clip, thus reducing the installation efficiency of the wire clip by the staff to a certain extent, and provide a shooting gun self-locking S-shaped drainage wire clip for a distribution network.

[0024] In order to better understand the present invention, the content of the present invention is further explained below in conjunction with embodiments, but the content of the present invention is not limited to the following embodiments.

[0025] like Figures 1-4As shown in the figure, a self-locking S-shaped drainage wire clamp for a distribution network includes a wire clamp 2, and a main cavity 201 and a secondary cavity 202 provided on the left and right sides of the wire clamp 2. Screw holes are provided on the inner walls of the main cavity 201 and the secondary cavity 202. The two screw holes are respectively threadedly connected to a lifting ring screw 4 and a hexagonal screw 1. After the lifting ring screw 4 and the hexagonal screw 1 pass through the screw holes from outside the wire clamp 2 into the main cavity 201 and the secondary cavity 202 respectively, locking blocks 3 are rotatably connected. Workers can rotate the hexagonal screw 1 on the ground to cooperate with the corresponding screw hole to press the corresponding locking block 3, thereby locking and positioning the secondary cable 6 into the secondary cavity 202, thus completing the connection and installation of the secondary cable 6 and the wire clamp 2 on the ground. Workers can press the main cable 7 through the lifting ring screw 4 in cooperation with the corresponding screw hole, thereby locking and positioning the main cable 7 into the main cavity 201, thus completing the connection and installation of the main cable 7 and the wire clamp 2.

[0026] Notches are provided at the opposite ends of the main cavity 201 and the secondary cavity 202. The notch of the main cavity 201 is provided to facilitate workers to control the displacement of the wire clamp 2 through a shooting gun operating rod, so that the main cable 7 enters the main cavity 201 and the wire clamp 2 is hung on the main cable 7. The notch of the secondary cavity 202 is provided to facilitate workers to send the secondary cable 6 into the secondary cavity 202, and then facilitate workers to stably connect the secondary cable 6 with the wire clamp 2 through the corresponding locking block 3 and the hexagonal screw 1.

[0027] The screw hole provided on the inner wall of the secondary cavity 202 is provided on the upper side wall of the secondary cavity 202. The screw hole of the secondary cavity 202 is threadedly connected to the hexagonal screw 1. The screw hole provided on the inner wall of the main cavity 201 is provided on the lower side wall of the main cavity 201. The screw hole of the main cavity 201 is threadedly connected to the lifting ring screw 4. The setting of the two screw holes makes the hexagonal screw 1 and the lifting ring screw 4 mirror-distributed. Then, after the workers position the secondary cable 6 on the wire clamp 2 through the hexagonal screw 1 on the ground, the workers can operate the wire clamp 2 connected to the secondary cable 6 to move through the shooting gun operating rod so that the notch opened on the main cavity 201 corresponds to the main cable 7, thus facilitating the workers to control the main cavity 201 to be hung on the main cable 7 through the shooting gun operating rod on the ground for subsequent operations.

[0028] The mirror distribution of the hexagonal screw 1 and the lifting ring screw 4 can also make the weight of the secondary cable 6 press on the locking block 3 rotatably connected to the hexagonal screw 1 when the shooting gun operating rod pushes the wire clamp 2 to move and connect with the main cable 7, thereby increasing the axial tension of the hexagonal screw 1, that is, increasing the axial pressing force between the hexagonal screw 1 and the corresponding screw hole, thus reducing the probability of the secondary cable 6 loosening between the secondary cavity 202 and the locking block 3 provided therein when the wire clamp 2 moves to be docked with the main cable 7, and further improving the stability of the workers to push the wire clamp 2 to move.

[0029] The eyebolt 4 includes a smooth shaft section 401 whose end is rotatably connected to the corresponding locking block 3 and an eyebolt loop 403 disposed away from the locking block 3. The smooth shaft section 401 can be subjected to a driving force to enable the eyebolt 4 to slide rapidly in the threaded hole of the main cavity 201, so that when the main cable 7 is hung into the main cavity 201, the staff can push the locking block 3 to quickly approach the main cable 7, that is, there is no need for the staff to rotate the eyebolt 4 multiple times to cooperate with the threaded hole of the main cavity 201 to push the locking block 3 close to the main cable 7.

[0030] A threaded section 402 that is threadedly engaged with the threaded hole of the main cavity 201 is provided between the smooth shaft section 401 and the eyebolt loop 403. The threaded section 402 can be docked with the threaded hole of the main cavity 201 when the locking block 3 approaches the main cable 7. Subsequently, the staff can rotate the eyebolt loop 403 through the shooting rod to drive the threaded section 402 to rotate. Then, through the threaded engagement between the threaded section 402 and the main cavity 201, the locking block 3 rotatably connected to the smooth shaft section 401 is pushed to press against the main cable 7. At the same time, the locking and positioning are achieved through the self-locking of the threaded section 402 and the threaded hole of the main cavity 201. After that, the locking block 3 rotatably connected to the smooth shaft section 401 can cooperate with the main cavity 201 to lock the main cable 7, thus completing the rapid connection between the main cable 7 and the wire clamp 2, that is, improving the connection efficiency between the main cable 7 and the wire clamp 2 to a certain extent. The vertical length of the threaded section 402 is greater than the vertical length of the threaded hole of the main cavity 201, thereby maintaining the stability of the threaded self-locking function between the threaded section 402 and the threaded hole of the main cavity 201, and thus maintaining the connection stability between the wire clamp 2 and the main cable 7.

[0031] A spring 5 is wound around the outer periphery of the smooth shaft section 401. The spring 5 is disposed between the locking block 3 rotatably connected to the end of the smooth shaft section 401 and the inner wall of one side of the main cavity 201 facing the eyebolt loop 403. The cross-section of the spring 5 is tapered, so that the spring 5 can be compressed to a great extent. Subsequently, the locking block 3 in the main cavity 201 can approach the inner wall of the lower side of the main cavity 201 to the greatest extent, thereby reducing the amount by which the locking block 3 blocks the notch of the main cavity 201, so that the notch of the main cavity 201 is larger, which is convenient for the staff to control the connection between the wire clamp 2 and the main cable 7.

[0032] The setting of the spring 5 can assist the staff to push the locking block 3 rotatably connected to the end of the smooth shaft section 401 close to the main cable 7 when the shooting rod releases the eyebolt loop 403, and assist the staff to quickly dock the threaded hole of the main cavity 201 with the threaded section 402, thereby assisting the staff to further improve the efficiency of stably connecting the wire clamp 2 and the main cable 7.

[0033] The spring 5 can cooperate with the eyebolt 4 to maintain the connection stability between the shooting rod and the wire clamp 2, thus facilitating the staff to control the docking between the wire clamp 2 and the main cable 7.

[0034] The arrangement of the spring 5 can apply axial pressure to the eyebolt 4 through the cooperation of the locking block 3 and the main cavity 201. Subsequently, the axial pressure between the optical axis section 401 and the threaded hole of the main cavity 201 can be increased, thereby reducing the loosening of the optical axis section 401 in the threaded hole of the main cavity 201, and further improving the stability of the connection between the main cable 7 and the wire clamp 2 to a certain extent.

[0035] The eyebolt loop 403 can be connected to the hook of the shooting rod. Thus, it is convenient for the staff to rotate the eyebolt loop 403 through the shooting rod, and then the entire eyebolt 4 can be driven to rotate. The eyebolt loop 403 can also be pulled by the hook of the shooting rod and retracted into the groove at the end of the shooting rod, so that the end of the shooting rod presses against the wire clamp 2, causing the wire clamp 2 to move with the shooting rod, and then the wire clamp 2 moves with the shooting rod to send the main cable 7 into the main cavity 201.

[0036] Fitting grooves 302 are formed on the side surfaces of the locking block 3 facing away from the eyebolt 4 or the hexagonal screw 1. The inner walls of the main cavity 201 and the auxiliary cavity 202 opposite to the fitting grooves 302 are both arranged in an arc shape, and the fitting grooves 302 are adapted to the arc-shaped inner walls of the arc-shaped main cavity 201 and auxiliary cavity 202. The arrangements of the locking block 3, the inner wall of the main cavity 201 and the inner wall of the auxiliary cavity 202 can make the locking block 3 cooperate with the main cavity 201 or the auxiliary cavity 202 to closely fit with the main cable 7 or the auxiliary cable 6, that is, increase the contact area between the locking block 3 and the main cavity 201 or the auxiliary cavity 202 and the main cable 7 or the auxiliary cable 6, thereby increasing the frictional force of the connection between the locking block 3 and the main cavity 201 or the auxiliary cavity 202 and the main cable 7 or the auxiliary cable 6, and further improving the stability of the connection between the wire clamp 2 and the main cable 7 and the auxiliary cable 6.

[0037] A guiding inclined groove 301 is provided on the side of the locking block 3 facing the notch. The guiding inclined groove 301 cooperates with the rounded corners provided on the inner wall above the notch of the main cavity 201. Thus, when the staff moves the wire clamp 2 to connect with the main cable 7 through the shooting rod, it guides the main cable 7 into the main cavity 201, thereby increasing the speed at which the staff connects the main cable 7 to the main cavity 201, and further improving the efficiency of the staff in connecting the wire clamp 2 and the main cable 7.

[0038] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various deformations or modifications within the scope of the claims, which do not affect the essence of the present invention.
