Detailed implementation manners

[0039] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0040] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0041] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate from or mutually exclusive of other embodiments selectively.

[0042] Furthermore, the present invention is described in detail in conjunction with the schematic diagrams. When detailing the embodiments of the present invention, for the convenience of description, the cross-sectional views showing the device structures will be enlarged locally not in accordance with the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0043] Example 1, reference Figures 1 to 5 , a quick-connection guide-type electric energy meter is provided, including a meter body 100, which is provided with a wiring hole 101, the wiring hole 101 is used to connect the wire 600, the wire 600 is inserted from the wiring hole 101, the number of the wiring holes 101 is set according to actual needs, generally four wiring holes 101 are used, namely, a live wire access hole, a live wire outlet hole, a neutral wire access hole, and a neutral wire outlet hole, a wiring piece is arranged on the inner side of each wiring hole 101, and the wiring piece is used to be electrically connected to the internal electronic components of the meter, the meter body 100 is provided with a side compartment 102 beside the wiring hole 101, and each wiring hole 101 is provided with a side compartment 102, reference Figure 2 and Figure 3 The meter body 100 is also provided with a connecting channel 103 connecting the wiring hole 101 and the side compartment 102 ; one end of the connecting channel 103 is connected to the side compartment 102 , and the other end is connected to the wiring hole 101 .

[0044] refer to Figure 2 and Figure 3 The quick-connection rail-type electric energy meter also includes a rotating buckle mechanism 200, including a rotating part 201 rotatably connected to the meter body 100, and an abutment part 202 connected to the rotating part 201, wherein the rotating part 201 can be positioned when it rotates toward the meter body 100 and fits with the meter body 100. The positioning method of the rotating part 201 can adopt a buckle structure or other positioning methods, refer to Figure 3 and Figure 5 In this embodiment, one end of the rotating part 201 is rotatably installed on the inner side of the side compartment 102 through a rotating shaft structure, and the other end extends to the outside of the side compartment 102. The interference part 202 is fixed to one end of the rotating part 201 located in the side compartment 102. When the rotating part 201 rotates, it can drive the interference part 202 to rotate synchronously.

[0045] Please refer to Figure 3 and Figure 5 The quick-connect rail-type electric energy meter also includes a line positioning mechanism 300, including a transmission rotating plate 301 rotatably installed inside the side compartment 102, and a positioning pin component 302 slidably arranged inside the connecting channel 103; one end of the positioning pin component 302 extends to the inside of the side compartment 102, and one end of the transmission rotating plate 301 is rotatably installed on the inner side of the side compartment 102.

[0046] Please refer to Figure 3 and Figure 5, the transmission rotating piece 301 extends between the positioning pin component 302 and the abutting part 202. The transmission rotating piece 301 has a force-receiving side 301a and a force-applying side 301b. The force-receiving side 301a of the transmission rotating piece 301 contacts the abutting part 202, and the force-applying side 301b of the transmission rotating piece 301 contacts the positioning pin component 302. When the rotating buckle mechanism 200 rotates towards the direction close to the watch body 100, the abutting part 202 and the transmission rotating piece 301 can push the positioning pin component 302 to move towards the wiring hole 101.

[0047] Therefore, when connecting the electric wire 600, the electric wire 600 is directly inserted into the inner side of the wiring hole 101, the rotating part 201 is rotated towards the direction close to the watch body 100. The rotating part 201 drives the abutting part 202 to rotate. The abutting part 202 pushes the transmission rotating piece 301 to rotate from the force-receiving side 301a. The force-applying side 301b of the transmission rotating piece 301 presses the positioning pin component 302. One end of the positioning pin component 302 extends from the inner side of the connection channel 103 to the inner side of the wiring hole 101, positioning one end of the electric wire 600 inside the wiring hole 101, and thus the connection between the electric wire 600 and the watch body 100 can be completed.

[0048] Specifically, please refer to Figure 3 and Figure 5 , a pressing protrusion 202a is provided on the abutting part 202. When the rotating part 201 does not rotate, the pressing protrusion 202a does not contact the force-receiving side 301a of the transmission rotating piece 301. When the rotating part 201 rotates towards the direction close to the watch body 100, the pressing protrusion 202a rotates synchronously to press the force-receiving side 301a of the transmission rotating piece 301.

[0049] Furthermore, please refer to Figure 3 and Figure 5 , the positioning pin component 302 includes a fixed ring 302a fixed to the inner side of the connection channel 103; a sliding column 302b slidably mounted on the fixed ring 302a; an extrusion block 302c provided at one end of the sliding column 302b, and the extrusion block 302c abuts against the transmission rotating piece 301; a contact head 302d provided at the end of the sliding column 302b close to the wiring hole 101; a first elastic member 302e sleeved on the outer side of the sliding column 302b, with one end abutting against the fixed ring 302a and the other end abutting against the extrusion block 302c.

[0050] In this embodiment, the cross-section of the connection channel 103 is circular, and the outer wall of the radial diameter of the fixed ring 302a fits with the inner wall of the connection channel 103. The first elastic member 302e is a spring. When not under force, the first elastic member 302e can limit the extrusion block 302c, so that the extrusion block 302c will not easily move towards the wiring hole 101, and also prevent the contact head 302d from entering the inner side of the wiring hole 101 when the electric wire 600 is not inserted.

[0051] When pressing the extrusion block 302c on the force - applying side 301b of the transmission rotating piece 301, the extrusion block 302c pushes the sliding column 302b and the contact head 302d to move towards the wiring hole 101. At this time, the extrusion block 302c presses the first elastic member 302e. Therefore, when disassembling the wire 600, rotate the rotating part 201 in the direction away from the meter body 100 to relieve the pressure on the extrusion block 302c. At this time, the first elastic member 302e can push the extrusion block 302c so that the contact head 302d returns to the inner side of the connection channel 103 again.

[0052] Among them, the contact head 302d is made of insulating material, preferably rubber material.

[0053] Example 2, please refer to Figure 5 , what is different from the first embodiment in this embodiment is that: a receiving groove 104 is further opened on the meter body 100, and one end of the receiving groove 104 communicates with the wiring hole 101; the quick - wiring rail - type electric energy meter further includes a bending mechanism 400, and the bending mechanism 400 includes a side - sliding member 401 slidably arranged on the rotating part 201, and a pressing member 402 connected to the side - sliding member 401.

[0054] Refer to Figure 5 , the purpose of setting the bending mechanism 400 and the receiving groove 104 is that when the wire 600 is connected to the meter body 100, a bending section 601 can be formed. After the wire 600 is inserted into the inner side of the wiring hole 101, rotate the rotating part 201 in the direction close to the meter body 100, the contact head 302d abuts to provide friction force to the end of the wire 600, and then the pressing member 402 will push the part of the wire 600 located outside the wiring hole 101, so that this part of the wire 600 forms a bending section 601.

[0055] This bending section 601 has three effects:

[0056] First, when the wire 600 is pulled by an external force, it can play a role in unloading the force, avoiding the problem that the pulling force is directly transmitted to the connection part of the wire 600 and the meter body 100, resulting in disconnection.

[0057] Second, it provides a compensation amount. Refer to Figure 7 and Figure 8 , when this electric meter is installed on the track, if the position needs to be adjusted, the bending section 601 can be unfolded. As in Figure 8 , the bending section 601 enters the compensation state, avoiding the problem that the whole electric meter is difficult to move due to the limitation of the wire 600.

[0058] Third, the bending section 601 can facilitate the detection by a clamp - type ammeter. When detecting with a clamp - type ammeter, the clamp head can be more conveniently buckled into the bending area 602 of the bending section 601.

[0059] The pressing member 402 includes a connecting rod 402a connecting the side-sliding member 401 and a pushing body 402b connected to the connecting rod 402a.

[0060] Referring to Figure 6 , specifically, the bending mechanism 400 further includes a force-applying member 403 fixed to the rotating portion 201 and a second elastic member 404 disposed between the force-applying member 403 and the pressing member 402; the second elastic member 404 can apply a pulling force to the pressing member 402 in the direction towards the force-applying member 403. A through groove 201a is formed in the rotating portion 201, and the through groove 201a is parallel to the extending direction of the rotating portion 201. After the wire 600 is pushed to form a bent section 601, the second elastic member 404 can pull the pressing member 402, so that the pressing member 402 is separated from the bent section 601 of the wire 600, enabling the bent section 601 of the wire 600 to have a deformable space.

[0061] The second elastic member 404 is a hook spring.

[0062] Please refer to Figure 9 , further, a first convex column 401a is provided on the side-sliding member 401; a first sliding groove 203 is formed in the rotating portion 201, and the first convex column 401a extends to the inside of the first sliding groove 203. The first sliding groove 203 has an extending section 203a and a first buckling section 203b provided at one end of the extending section 203a; when the first convex column 401a is located in the first buckling section 203b, the second elastic member 404 cannot pull the pressing member 402 to move.

[0063] When installing the wire 600, the first convex column 401a cannot break away from the inside of the first buckling section 203b. At this time, the pulling force of the second elastic member 404 can tighten the pressing member 402, thereby applying a pulling force to the side-sliding member 401, so that the first convex column 401a in the side-sliding member 401 remains inside the first buckling section 203b. After the wire 600 is connected, the side-sliding member 401 is pushed, so that the first convex column 401a breaks away from the first buckling section 203b. At this time, the second elastic member 404 can pull the pressing member 402 to move, and the first convex column 401a moves along the extending section 203a, so that the pressing member 402 moves away from the formed bent section 601, thus not affecting the deformation of the bent section 601 when it is stressed.

[0064] Please refer to Figure 5 、 Figure 9 and Figure 10, in this embodiment, the number of the side-sliding members 401 is two, which are respectively located on both sides of the rotating portion 201. First sliding grooves 203 are formed on both sides of the rotating portion 201. The pressing member 402 has two connecting rods 402a, and the two connecting rods 402a are respectively connected to the two side-sliding members 401. The pushing body 402b is located between the two connecting rods 402a and is used to push the electric wire 600 to form a bent section 601.

[0065] All the other structures are the same as those in Embodiment 1.

[0066] Embodiment 3, referring to Figure 9 and Figure 10 , the difference between this embodiment and the above embodiments is that: the side-sliding member 401 is further provided with a second convex column 401b; a second sliding groove 204 is further formed on the rotating portion 201. The second sliding groove 204 includes a parallel section 204a parallel to the extension section 203a, a second buckling section 204b corresponding to the position of the first buckling section 203b, and an arc section 204c connecting the second buckling section 204b and the parallel section 204a.

[0067] In this embodiment, the first buckling section 203b and the second buckling section 204b are in a parallel state, and the arc section 204c takes the connection point of the first buckling section 203b and the extension section 203a as the center of the circle.

[0068] The purpose of using the second convex column 401b and the second sliding groove 204 is to enable the pushing body 402b to expand the bent section 601 when in the contact positioning state. Refer to Figure 9 , when in the positioning state, the first convex column 401a is located inside the first buckling section 203b, and the second convex column 401b is located inside the second buckling section 204b. When unlocking, the first convex column 401a and the second convex column 401b respectively disengage from the first buckling section 203b and the second buckling section 204b.

[0069] At this time, the first convex column 401a reaches the connection point of the first buckling section 203b and the extension section 203a, while the second convex column 401b reaches the arc section 204c. Under the pulling force of the second elastic member 404, the second convex column 401b enters the inside of the arc section 204c and moves inside the arc section 204c. During this process, the first convex column 401a is located at the connection point of the first buckling section 203b and the extension section 203a as the rotation center. Therefore, the entire side-sliding member 401 rotates around the first convex column 401a as the center of the circle. Refer to Figure 10 , during this process, the connecting rod 402a and the pushing body 402b also rotate. The rotating pushing body 402b will expand the bent section 601, thereby enhancing the effect of the bent section 601.

[0070] Refer to Figure 9, specifically, the side slider 401 further has a protruding end 401c. When the rotating part 201 rotates close to the watch body 100, the protruding end 401c can contact the watch body 100.

[0071] Therefore, when the rotating part 201 fits close to the watch body 100, the protruding end 401c will first contact the watch body 100. The protruding end 401c is stressed, causing the side slider 401 to drive the first convex post 401a and the second convex post 401b to disengage from the first buckling section 203b and the second buckling section 204b respectively, thereby automatically releasing the positioning state of the side slider 401.

[0072] All other structures are the same as those in Embodiment 2.

[0073] Embodiment 4, refer to Figure 1 and Figure 10 , the difference between this embodiment and the above embodiments is that: a convex buckle 500 is provided on the watch body 100, and a buckle groove 401d is formed on the side slider 401. When the convex buckle 500 is located inside the buckle groove 401d, the rotating part 201 cannot rotate.

[0074] The installation position of the convex buckle 500 corresponds to the position of the side slider 401.

[0075] When the second elastic member 404 pulls the pressing member 402, it will drive the side slider 401 to move. At this time, the first convex post 401a moves inside the first sliding groove 203, and the second convex post 401b moves inside the second sliding groove 204, driving the side slider 401 to approach the convex buckle 500. The convex buckle 500 enters the inner side of the buckle groove 401d to complete the locking of the entire rotating part 201.

[0076] All other structures are the same as those in Embodiment 3.
