[0056] Figure 1An assembly drawing of the push-pull structure according to an embodiment of the present application is shown. Figure 2 An assembly drawing of the other side of the push-pull structure according to an embodiment of the present application is shown. Figure 3 An isometric assembly drawing of the push-pull structure according to an embodiment of the present application is shown. Figure 4 A structure diagram of the movable plug rod of the push-pull structure according to an embodiment of the present application is shown. Figure 5 A structure diagram of the fixed plug rod of the push-pull structure according to an embodiment of the present application is shown; as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 or Figure 5 shown, the push-pull structure includes: a fixed plug rod 100, a movable plug rod 200, and a movable member 300. Among them, the fixed plug rod 100 is detachably installed on the electric meter connector. A through hole is provided on the fixed plug rod 100, and the through hole is provided along the axial direction of the fixed plug rod 100. A sliding groove 110 is provided on the rod body of the fixed plug rod 100, and the sliding groove 110 communicates with the through hole. The movable plug rod 200 is movably installed in the through hole, and the movable plug rod 200 matches the through hole so that the movable plug rod 200 is slidably arranged in the through hole. A blind hole is provided at one end of the movable plug rod 200, and an elastic member 400 is installed in the blind hole. A slot 210 is provided on the rod body of the movable plug rod 200, and the slot 210 communicates with the blind hole. The movable member 300 is slidably installed on the electric meter connector. The movable member 300 is provided with an abutting portion 310. The abutting portion 310 sequentially passes through the sliding groove 110 and the slot 210, and the abutting portion 310 abuts against the elastic member 400. One end of the elastic member 400 that does not abut against the abutting portion 310 abuts against the movable plug rod 200 so that the elastic member 400 pushes the end of the movable plug rod 200 without the blind hole out of the through hole of the fixed plug rod 100.

[0057] In the push-pull structure of the embodiment of the present application, there are a fixed insertion rod 100, a movable insertion rod 200, a movable member 300, and an elastic member 400. During installation, first, the fixed insertion rod 100 is installed on the electricity meter connector. Then, the elastic member 400 is placed into the blind hole of the movable insertion rod 200, and one end of the elastic member 400 abuts against the blind hole. After that, the movable insertion rod 200 is placed into the through hole of the fixed insertion rod 100. The position of the slot 210 on the movable insertion rod 200 is adjusted so that the slot 210 on the movable insertion rod 200 is disposed opposite to the sliding slot 110 on the fixed insertion rod 100. The movable member 300 is slidably installed on the electricity meter connector, and the abutting portion 310 of the movable member 300 is inserted into the sliding slot 110 and the slot 210, and the abutting portion 310 abuts against the other end of the elastic member 400. Thus, the installation is completed. During insertion, first, the movable member 300 is pushed, and the movable insertion rod 200 is driven by the movable member 300 to move in the through hole along the sliding slot 110. When the movable insertion rod 200 reaches a certain position, the movable member 300 will squeeze the elastic member 400, and the elastic member 400 will squeeze the movable insertion rod 200. Thus, the movable insertion rod 200 will continue to move in the blind hole until one end (the head part) of the movable insertion rod 200 exposes from the through hole on the fixed insertion rod 100. Through the above structure, when the fixed insertion rod 100 is inserted into the socket of the electricity meter, the top of the fixed insertion rod 100 will have the movable insertion rod 200 exposed, making the contact between the embodiment of the present application and the socket of the electricity meter closer, solving the problem that the head of the fixed insertion rod 100 is not tightly connected to the electricity meter due to the processing errors of the fixed insertion rod 100 and the electricity meter, and avoiding the situation of poor contact.

[0058] Here, it should be noted that both the fixed insertion rod 100 and the movable insertion rod 200 are made of conductive materials.

[0059] Here, it should also be noted that in a possible implementation manner, the sliding slot 110 is a through slot that penetrates the opposite side walls of the fixed insertion rod 100.

[0060] Here, it should also be noted that in a possible implementation manner, the length of the movable insertion rod 200 is greater than the length of the sliding slot 110. Thus, it can prevent the movable insertion rod 200 from falling in the sliding slot.

[0061] In a possible implementation, the movable insertion rod 200 includes a first expansion rod 230 and a mounting rod 220. Among them, the first expansion rod 230 is in the shape of an expansion head, the mounting rod 220 is fixedly installed at one end of the first expansion rod 230, and a blind hole is opened at the end of the mounting rod 220 facing away from the first expansion rod 230. Both the first expansion rod 230 and the mounting rod 220 are matched with the through hole. Thus, by making one end of the movable insertion rod 200 in the shape of an expansion head, one end of the movable insertion rod 200 is provided with elasticity, making it easier for the movable insertion rod 200 to pass through the through hole and exposing the end of the first expansion rod 230 facing away from the mounting rod 220 out of the through hole of the fixed insertion rod 100.

[0062] Here, it should be noted that the expansion head shape means that a plurality of openings are opened on the rod body of the first expansion rod 230. The plurality of openings are opened along the axial direction of the first expansion rod 230 and are distributed around the axis of the first expansion rod 230 (which may or may not be evenly distributed), so that the cross-section of the first expansion rod 230 presents a petal shape. Further, in a possible implementation, the number of openings can be four, and the four openings are evenly distributed around the axis of the first expansion rod 230.

[0063] Here, it should also be noted that, in a possible implementation, the end of the first expansion rod 230 far from the mounting rod 220 (i.e., the head of the first expansion rod 230) is in the shape of a dome. Thus, the structure of the first expansion rod 230 in the embodiment of the present application is optimized, and the friction between the head of the first expansion rod 230 and the inner wall of the through hole is avoided when the first expansion rod 230 slides in the through hole.

[0064] Here, it should also be noted that, in a possible implementation, the movable insertion rod 200 is integrally formed. Thus, it is convenient for the manufacture of the movable insertion rod 200.

[0065] Here, it should also be noted that the through hole can be a circular hole, and the movable insertion rod 200 can be a cylindrical rod. The side wall of the first expansion rod 230 is flush with the side wall of the mounting rod 220. Thus, the structure of the movable insertion rod 200 in the embodiment of the present application is optimized.

[0066] In a possible implementation, a mounting hole 140 is opened on the fixed insertion rod 100. The mounting hole 140 is arranged beside the sliding groove 110. The mounting hole 140 is used for detachably installing a fixing member, so that the fixed insertion rod 100 is detachably connected to the electricity meter connector through the fixing member. Thus, the setting of the mounting hole 140 facilitates the fixing of the fixed insertion rod 100 to the electricity meter connector.

[0067] Here, it should be noted that, in a possible implementation, the mounting hole 140 can be a threaded hole. Thus, it is more convenient to fix the fixing member.

[0068] Furthermore, in a possible implementation, the fixed plug rod 100 includes a second expansion rod 120 and a fixed portion 130, the fixed portion 130 is block-shaped, the second expansion rod 120 is in the shape of an expansion head, and the fixed portion 130 is fixed to a section of the second expansion rod 120. A through hole is provided on the fixed portion 130, and passes through the fixed portion 130 along the axial direction of the second expansion rod 120, and the through hole matches the inner hole of the second expansion rod 120. The sliding groove 110 and the mounting hole 140 are both provided on the fixed portion 130, and the sliding groove 110 is connected to the through hole. A through hole for passing the wire is provided on the fixed portion 130, the through hole is provided on the side of the sliding groove, and the axis of the through hole is arranged parallel to the axis of the second expansion rod 120, and the through hole passes through the fixed portion 130. Therefore, the setting of the second expansion rod 120 makes the fixed plug rod 100 elastic, so that the movable plug rod 200 can be more easily passed through the second expansion rod 120. Furthermore, by providing the through holes, it is easier to pass the wires through the embodiment of the present application.

[0069] Here, it should be noted that, in a possible implementation, the slot opening of the sliding slot 110 is in the shape of an oblong hole, and the slot width of the sliding slot 110 is smaller than the diameter of the through hole, and the central axis of the sliding slot 110 along the length direction is coaxial with the axis of the through hole. The slot width of the sliding slot 110 is greater than or equal to the slot width of the slot 210. Thus, the structure of the embodiment of the present application is further optimized.

[0070] Here, it should also be noted that, in a possible implementation, the length of the second expansion rod 120 is less than the length of the moving rod 200. Thus, the structure of the embodiment of the present application is more reasonable, and the phenomenon of not being able to move into place is prevented.

[0071] Furthermore, in a possible implementation, the fixing portion 130 includes a first block 131 and a second block 132, wherein the second expansion rod 120 is fixed to one end of the first block 131, and the through hole and the sliding groove 110 are both provided on the first block 131. The second block 132 is fixed to the side of the first block 131, the first block 131 and the second block 132 are arranged in an "L" shape, and the second block 132 is arranged away from the second expansion rod 120. The through hole and the mounting hole 140 are both arranged on the second block 132, and the through hole is arranged to penetrate the second block 132. Thus, the structure of the embodiment of the present application is further optimized.

[0072] Here, it should be noted that, in a possible implementation, there may be more than two mounting holes 140, and the more than two mounting holes 140 are sequentially arranged along the axial direction of the through hole. Here, it should also be noted that, in a possible implementation, the through hole and the mounting hole 140 are arranged in communication. Furthermore, there are two mounting holes 140.

[0073] In a possible implementation, the cross-section of the notch of the slot 210 can be in the shape of an oblong hole, thereby further optimizing the structure of the embodiment of the present application.

[0074] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 or Figure 7 As shown, in a possible implementation, the moving member 300 further includes a push plate 320 and a slider 330. Among them, the slider 330 is in the shape of a "T"-shaped plate, and one side plate surface of the push plate 320 is fixed to the slider 330, so that the push plate 320 and the slider 330 are connected in an "I" shape. The abutting portion 310 is in the shape of a plate, and the abutting portion 310 is vertically arranged on the side of the slider 330 away from the push plate 320. Thus, the structure of the embodiment of the present application is made more reasonable. The abutting portion 310 can be driven to move by pushing the slide plate, and the slider 330 is set in a "T" shape to prevent the moving member 300 from being pulled out in the vertical sliding direction.

[0075] Here, it should be noted that, in a possible implementation, an anti-slip layer is provided on the plate surface of the push plate 320 facing away from the slider 330, so as to increase the friction of the plate surface of the push plate 320.

[0076] Here, it should also be noted that, in a possible implementation, the anti-slip layer includes a plurality of convex ribs, and the plurality of convex ribs are arranged at intervals in sequence along the pushing direction of the push plate 320. Further, in a possible implementation, the convex ribs are in the shape of triangular prisms, and an included angle is provided between the axis of the convex ribs and the pushing direction of the push plate 320 (for example: the axis of the convex ribs is perpendicular to the pushing direction of the push plate 320). Thus, the friction of the plate surface of the push plate 320 can be increased, and the manufacturing is simple.

[0077] Here, it should also be noted that, in a possible implementation, there are four convex ribs, and the four convex ribs are arranged at equal intervals in sequence along the pushing direction of the push plate 320.

[0078] Here, it should also be noted that, in a possible implementation, the abutting portion 310 is flush with one end of the slider 330. Thus, the structure of the embodiment of the present application is further optimized.

[0079] Here, it should also be noted that in a possible implementation, the push plate 320 includes a connecting plate 321 and a folding plate 322. Among them, the connecting plate 321 is in the shape of a rectangular plate, and a cut-out is provided at one corner of the connecting plate 321. The convex rib is provided on the side of the connecting plate 321 where there is no cut-out. The slider 330 is fixed to the bottom of the connecting plate 321. The folding plate 322 is in the shape of a "Z" - shaped plate. One end of the folding plate 322 is fixedly connected to the side wall of the connecting plate 321, and the folding plate 322 is arranged on the same side as the side of the connecting plate 321 where the cut-out is provided, and the folding plate 322 is located on the side wall of the connecting plate 321 where there is no cut-out. The bottom of the folding plate 322 is flush with the bottom of the connecting plate 321. Thus, the structure of the moving member 300 is further optimized. And by setting the folding plate 322 as a "Z" - shaped structure, it can cooperate with the cover at the bottom of the electric meter, so as to achieve the anti - theft function.

[0080] Here, it should also be noted that in a possible implementation, the cross - section of the abutting portion 310 in the vertical direction is trapezoidal.

[0081] In a possible implementation, the elastic member 400 is a spring.

[0082] In a possible implementation, the ratio of the length of the movable insertion rod 200 to the length of the fixed insertion rod 100 is between 1 / 2 and 4 / 5, and the length of the fixed block in the fixed insertion rod 100 along the axis direction of the second expansion rod 120 is less than the length of the movable insertion rod 200. Further, the ratio of the length of the movable insertion rod 200 to the length of the fixed insertion rod 100 is 3 / 5. That is, when the length of the movable insertion rod 200 is 37 mm, the fixed insertion rod 100 can be 60 mm, and the length of the fixed block along the axis direction of the second expansion rod 120 can be 36 mm.

[0083] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 or Figure 10As shown, based on the push-pull structure described above, the present disclosure also provides an electricity meter connector. Among them, the electricity meter connector of the embodiment of the present disclosure includes the push-pull structure described above and a base body 500. Among them, an installation cavity 510 is provided on the base body 500, and an opening is provided on one side of the installation cavity 510. The fixed insertion rod 100 is detachably installed inside the installation cavity 510, and a part of the fixed insertion rod 100 extends out of the installation cavity 510. A slideway 520 is provided on the base body 500, the slideway 520 communicates with the installation cavity 510, the slideway 520 is arranged along the axial direction of the fixed insertion rod 100, and the moving member 300 is slidably connected to the slideway 520. Thus, in the embodiment of the present application, the moving insertion rod 200 can be driven to move inside the fixed insertion rod 100 by pushing the moving member 300 on the slideway 520. When the moving insertion rod 200 moves to a certain position, the elastic member 400 is squeezed by the abutting portion 310, and the elastic member 400 drives the moving insertion rod 200 to move. Thus, the contact between the embodiment of the present application and the socket of the electricity meter is closer, solving the problem that the head of the fixed insertion rod 100 is not tightly connected to the electricity meter due to the processing error between the fixed insertion rod 100 and the electricity meter, and avoiding the situation of poor contact.

[0084] Here, it should be noted that, in a possible implementation manner, the first expansion rod 230 of the fixed insertion rod 100 extends out of the installation cavity 510 from the opening of the installation cavity 510.

[0085] Furthermore, in a possible implementation manner, it further includes a fixing member.
