Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, an electric power socket capable of automatically tightening firmness comprises a wall body 1, a socket 2 is arranged on the right side of the wall body 1, the socket 2 is made of anticorrosive plastic, so that equipment can be effectively prevented from being corroded, the service life of the equipment is greatly prolonged, the production cost is reduced, and the socket plays an indispensable role in enterprises, an arc-shaped through hole is formed in the left side of the socket 2, a linkage rod 7 is inserted through the arc-shaped through hole, so that the linkage rod 7 cannot be clamped by the socket 2 when moving, a receiving wheel 3 is arranged inside the socket 2, a pull rod 4 is meshed and connected with the inner surface of the receiving wheel 3, a backing plate 5 is fixedly connected to one side of the pull rod 4, which is far away from the receiving wheel 3, a fixing screw 6 is arranged on the right side of the backing plate 5 in an inserting manner, the linkage rod 7 is rotatably connected to the surface of the receiving wheel 3, a ratchet 8 is, when the socket 2 is reset, the ratchet 8 automatically resets and rotates, the air pumping plate 10 is driven to an initial position through the air pumping toothed bar 9, the surface of the ratchet 8 is meshed and connected with the ratchet rod 12, the ratchet rod 12 and the ratchet 8 are in one-way right meshing transmission, the inner wheel surface of the ratchet 8 is meshed and connected with the air pumping toothed bar 9, the air pumping toothed bar 9 is made of stainless steel and can effectively prevent equipment from being corroded, the air pumping plate 10 is fixedly connected to one side of the air pumping toothed bar 9, which is far away from the ratchet rod 12, the air pumping box 13 is slidably connected to the side of the air pumping plate 10, a one-way air outlet pipe is arranged on the side of the air pumping box 13, when the air pumping plate 10 is reset, air pumped from the air spring 15 is discharged through the one-way air outlet pipe, the guide pipe 14 is fixedly connected to one side of the air pumping box 13, which is far away from the ratchet rod 12, the one-way, the air spring 15 is in a non-contraction state at the beginning, and the support rods 11 are fixedly connected to both sides of the air spring 15.

In the process of pulling the plug out of the socket 2, once the socket 2 becomes loose, the socket 2 can drive the ratchet rod 12 to move towards the direction away from the wall body 1, the ratchet rod 8 generates meshing transmission, the ratchet 8 is driven to rotate anticlockwise, and the exhaust toothed bar 9 meshed with the ratchet 8 is driven to move towards the direction close to the ratchet rod 12 through the inner wheel of the ratchet 8.

The air pumping plate 10 can move towards the direction close to the ratchet rod 12 in the air pumping box 13 under the driving of the air pumping toothed bar 9, because the air spring 15 is communicated with the air pumping box 13 through the guide pipe 14, the air inside the air spring 15 is pumped into the air pumping box 13 through the guide pipe 14 by the air pumping plate 10, so that the air spring 15 is contracted, the socket 2 is pulled through the support rod 11, and along with the increase of the gas pumped in the air spring 15, the larger the contraction force of the air spring 15 is, the stronger the tightening degree of the socket 2 is, therefore, when the plug is pulled out of the socket 2 again, the socket 2 is difficult to pull due to the contraction force of the air spring 15, and the effect of automatically tightening the firmness between the plug and the wall body 1 when the socket 2 is loosened is achieved.

Because when 8 anticlockwise rotations of ratchet wheel, and the trace 7 on surface is driven and is moved to the right, produce torsional force to takeover wheel 3, lead to takeover wheel 3 anticlockwise rotation, pull rod 4 with it meshing drives to keeping away from backing plate 5 direction and removes, both spur backing plate 5, because the side of backing plate 5 alternates and is provided with set screw 6, and set screw 6 is not hard up with wall body 1, so backing plate 5 is pulled and will spur set screw 6, lead to set screw 6 and wall body 1 to produce alternating force, can't drop, be provided with one-way cardboard again in the side of pull rod 4, with pull rod 4 one-way to being close to takeover wheel 3 direction meshing, consequently pull rod 4 can not reset the removal, so set screw 6 is lastingly tightened, thereby reached and prevented that set screw 6 from not hard up when not hard up from dropping from socket 2 and influencing the effect that socket 2 used.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
