[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0035] See Figures 1 to 10 A socket capable of adjusting the outlet direction of a cable by swinging its head comprises a bent pipe 1 and a base 2, wherein the base 2 is provided with a matching hole 21. The bent pipe 1 comprises an integrally formed horizontal pipe section 11 and a vertical pipe section 12, wherein the vertical pipe section 12 is rotatably arranged in the matching hole 21.

[0037] The lower end of the inner wall of the matching hole 21 is coaxially provided with a bottom side countersunk hole 212, and the bottom end of the vertical pipe section 12 is threadedly connected with a screw sleeve 3, which is in the bottom side countersunk hole 212, and a gap is left between the outer wall of the screw sleeve 3 and the side wall of the bottom side countersunk hole 212. The bottom end of the vertical pipe section 12 is sleeved with a wave spring 4, and the upper and lower sides of the wave spring 4 are respectively against the inner cavity top wall of the bottom side countersunk hole 212 and the screw sleeve 3.

[0038] Specifically, the gear teeth provided on the annular inner conical surface 211 and the annular outer conical surface 121 are all helical teeth, and the angle between the gear teeth and the central axis direction of the matching hole 21 (reference Figure 5 The medium β) is 30°-34°.

[0039] Specifically, an inner wall annular groove 213 is provided on the inner wall of the matching hole 21 , an inner wall sealing ring is provided in the inner wall annular groove 213 , and the inner wall sealing ring is closely attached to the outer wall of the vertical pipe section 12 .

[0040] Specifically, the bottom wall of the base 2 is provided with a bottom wall annular groove 22, and a bottom wall sealing ring is provided in the bottom wall annular groove 22. The bottom wall of the base 2 is provided with an outer flange, and the outer flange is provided with a plurality of connection holes 24. The base 2 is used to be installed at the place where the equipment is to be installed, and a mounting gasket 25 is provided between the place where the equipment is to be installed and the bottom wall of the base 2, and the bottom wall sealing ring is close to the mounting gasket 25.

[0041] Specifically, the end of the transverse pipe section 11 is sleeved with a semicircular shell 5, the semicircular shell 5 is connected to the elbow 1 by screws, and the front end outer wall of the semicircular shell 5 is provided with a thread (see Figure 1 The front end of the semicircular shell 5 is used for threaded connection with the plug 7. A pin insulator 6 is arranged inside the semicircular shell 5, and the pin insulator 6 is made of rubber. The outer wall of the pin insulator 6 is interference fit with the inner wall of the semicircular shell 5. The pin insulator 6 is penetrated by a plurality of conductive pins 61.

[0042] Specifically, the conductive pin 61 is provided with a middle shaft section 611 and a tail section 612, and the diameters of the middle shaft section 611 and the tail section 612 are larger than the main body diameter of the conductive pin 61. The pin insulator 6 is provided with a through hole, and the conductive pin 61 is inserted in the through hole, and the through hole is provided with a middle coarse hole section 62, and the middle shaft section 611 cooperates with the middle coarse hole section 62. The tail end of the middle shaft section 611 abuts against the tail end of the middle coarse hole section 62. The tail end of the through hole is provided with an end face countersunk hole 63, and the tail section 612 cooperates with the end face countersunk hole 63, and the front end of the tail section 612 abuts against the bottom of the end face countersunk hole 63.

[0043] Specifically, the circumferential outer wall of the conductive pin 61 is interference-fitted with the through hole of the pin insulator 6 .

[0044] Specifically, one of the conductive pins 61 is a ground conductive pin ( Figure 1 At point C in the middle, the tail end of the grounding conductive pin is connected to a grounding ring 64, and the edge of the grounding ring 64 is clamped by the front end of the transverse pipe section 11 and the semicircular shell 5.

[0045] The working principle of the socket of the utility model is as follows:

[0046] After the base 2 is installed on the equipment housing (not shown), the equipment cable enters the elbow 1 through the vertical pipe section 12, and each wire of the cable is welded to each conductive pin 61. Then, the threaded section ( Figure 1 D in the middle) is threadedly connected to the plug 7 (such as Fig. 9 ) to power on the device.

[0047] If the outlet direction of the cable connected to the plug 7 needs to be adjusted, the plug 7 can be rotated to make the gear teeth provided on the annular outer conical surface 121 and the gear teeth provided on the annular inner conical surface 211 rotate relative to each other and stagger the gear teeth by a certain number of teeth, so that the relative angle between the elbow 1 and the base 2 can be adjusted, thereby adjusting the outlet direction of the cable connected to the plug 7 (such as Fig.10 As shown). Every time the gear teeth provided on the annular outer conical surface 121 and the gear teeth provided on the annular inner conical surface 211 are misaligned by one tooth, the elbow 1 moves upward relative to the base 2 (compressing the wave spring 4) and then resets once. When the elbow 1 swings to a suitable angle position, the wave spring 4 keeps pushing the screw sleeve 3 downward, so that the gear teeth provided on the annular inner conical surface 211 and the gear teeth provided on the annular outer conical surface 121 remain meshed, thereby keeping the elbow 1 at this angle position. By adjusting the axial position of the screw sleeve 3, the preload of the wave spring 4 can be adjusted, thereby adjusting the thrust required for the gear to misalign, that is, to swing the elbow 1.

[0048] The gear teeth provided on the annular inner conical surface 211 and the annular outer conical surface 121 are all helical teeth, and the angle between the gear teeth and the central axis direction of the matching hole 21 (reference Figure 5The angle β) is 30°-34°, so that the bend 1 can be swung in the forward direction with less effort, but can be swung in the reverse direction with more effort, which is suitable for the occasions where the spontaneous reverse swing of the cable needs to be restricted.

[0049] The outer wall of the pin insulator 6 and the inner wall of the semicircular shell 5 are interference fit, making the fitting part liquid-tight, thereby preventing water or oil from penetrating. The circumferential outer wall of the conductive pin 61 and the perforation of the pin insulator 6 are interference fit, making the fitting part liquid-tight, thereby preventing water or oil from penetrating.

[0050] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
