The plug 4 is connected with the sockets 3 on the upper line board 1 and the lower line board 2 through wires. The structure of the receptacle 3 in this embodiment is shown in fig. 2, and is divided into a two-hole receptacle and a three-hole receptacle. Meanwhile, the number of the sockets 3 on the upper line board 1 and the lower line board 2 can be set arbitrarily according to actual conditions. The two-hole socket consists of a zero line insertion piece 28 and a live line insertion piece 29, and the three-hole socket consists of a zero line insertion piece 28, a live line insertion piece 29 and a grounding insertion piece 30. In both the two-hole socket and the three-hole socket, the zero line plug-in strip 28, the live line plug-in strip 29 and the grounding plug-in strip 30 are connected in parallel with each other through different conducting strips.

Example 2

This embodiment is a specific description of a first structure of the telescoping control assembly based on embodiment 1, and the structure of the telescoping control assembly described in this embodiment is shown in fig. 3.

As shown in fig. 3, the telescoping control assembly is an elastic rubber ring 8. This elastic rubber circle 8's middle part is equipped with the through-hole, flexible pillar 7 passes behind the through-hole of elastic rubber circle 8 and is in the same place with elastic rubber circle 8 fixed connection to make flexible pillar 7 and this elastic rubber circle 8 form a whole, slide along the pore wall of mounting hole 6 with the elastic rubber circle 8 of ensureing that flexible pillar 7 is synchronous. Because the elastic rubber ring 8 and the hole wall of the mounting hole 6 have friction, the upper line board 1 and the lower line board 2 cannot be easily folded after being separated, or the upper line board 1 and the lower line board 2 cannot be easily unfolded after being folded, so that the using state of the upper line board 1 and the lower line board is maintained.

Alternatively, the elastic rubber ring 8 is fixedly mounted on the wall of the mounting hole 6, and the telescopic support 7 is inserted into the through hole of the elastic rubber ring 8. At this time, when the telescopic pillar 7 moves inside the mounting hole 6, the elastic rubber ring 8 does not slide inside the mounting hole 6 together with the telescopic pillar 7, but the telescopic pillar 7 slides inside the through hole of the elastic rubber ring 8, which can also achieve the purpose of keeping the upper board 1 and the lower board 2 from being easily folded after being separated, or keeping the upper board 1 and the lower board 2 from being easily unfolded after being folded, so as to maintain the state of the upper board 1 and the lower board during use.

When the upper line plate 1 and the lower line plate 2 need to be separated for use, the upper line plate 1 and the lower line plate 2 only need to be pulled open by force; when the upper line plate 1 and the lower line plate 2 need to be folded for use, the upper line plate 1 and the lower line plate 2 only need to be folded by force. When the device is used, the distance between the upper line plate 1 and the lower line plate 2 can be controlled at will, namely, the distance between the upper line plate and the lower line plate can be adjusted according to a specific use environment.

Example 3

This embodiment is a specific description of a second structure of the telescoping control assembly based on embodiment 1, and the structure of the telescoping control assembly described in this embodiment is shown in fig. 4 and 5.

As shown in fig. 4 and 5, the telescoping control assembly of the present embodiment is composed of a mounting cavity 9 disposed inside the upper plate 1 and communicating with the mounting hole 6, a driving hole 10 disposed on an end surface of the upper plate 1 and communicating with the mounting cavity 9, and a rotating wheel 11 disposed inside the mounting cavity 9.

The rotating wheel 11 is preferably made of plastic material, and an internal threaded hole is formed in the center of the rotating wheel. When the rotating wheel 11 is installed inside the installation cavity 9, the outer side edge of the rotating wheel passes through the driving hole 10 and is exposed out of the end surface of the upper line plate 1, so that a user can apply external force to the rotating wheel 11 at the position of the driving hole 10 to rotate the rotating wheel.

In this embodiment, the surface of the telescopic support 7 needs to be provided with an external thread 12 matching the internal thread of the internally threaded hole, i.e. the telescopic support 7 is screwed with the internally threaded hole of the rotating wheel 11 by means of its external thread 12.

The operation principle of the embodiment is as follows: when needs are with line board 1 and the board 2 that rolls off the production line separately uses, only need clockwise rotation to rotate wheel 11, should rotate wheel 11 and just can rotate in the inside of installation cavity 9, because the spacing of installation cavity 9 and the interact of internal thread and external screw thread this moment, under the drive of rotating wheel 11, this telescopic support 7 just can be followed the inside of mounting hole 6 gradually and withdraw from to line board 1 is kept away from to line board 2 under the synchronous drive, finally reaches the purpose with line board 1 and the board 2 detached that rolls off the production line.

On the contrary, when needs fold the use with line board 1 and lower line board 2, only need anticlockwise rotation to rotate wheel 11, should rotate wheel 11 just can rotate in the inside of installation cavity 9, this moment because the spacing of installation cavity 9 and the interact of internal thread and external screw thread, should rotate wheel 11 and just can drive telescopic prop 7 and enter into inside 6 mounting holes gradually to line board 2 is close to line board 1 under the synchronous drive, finally reaches the purpose of folding line board 1 and lower line board 2.

It should be noted that the thread direction of the male thread 12 and the female thread direction of the female thread hole directly determine whether the telescopic strut 7 advances or retreats when the rotating wheel 11 is driven clockwise. Therefore, when the rotating wheel 11 is rotated clockwise as described above, the upper thread plate 1 and the lower thread plate 2 are separated from each other, and it can also be the case that the upper thread plate 1 and the lower thread plate 2 are folded with each other, which depends on the winding directions of the external thread 12 and the internal thread, and the principle is well known in the art and will not be described herein again.

Example 4

This embodiment is a specific description of a third structure of the telescoping control assembly based on embodiment 1, and the structure of the telescoping control assembly described in this embodiment is shown in fig. 6 to 8.

The telescopic control assembly comprises a toothed rotating piece 13 which is arranged on the telescopic support column 7 and can rotate, a guide groove 14 which is arranged on the inner wall of the mounting hole 6, and a spring 15 which is arranged inside the mounting hole 6 and is used for providing thrust to the telescopic support column 7 towards the outer side of the mounting hole 6.

The tooth-shaped rotating member 13 has a rectangular overall shape as shown in fig. 8, and two long sides of the tooth-shaped rotating member are parallel to each other, and a middle portion of two short sides of the tooth-shaped rotating member is recessed inward to form a V-shaped notch or a V-shaped notch is directly provided at a middle portion of the short sides, so that the entire tooth-shaped rotating member 13 has four tooth points, i.e., a left upper tooth point 31, a left lower tooth point 32, a right upper tooth point 33, and a right lower tooth point 34. Since the toothed rotor 13 is rectangular as a whole, the length of the long side of the toothed rotor 13 is longer than the length of the short side thereof.

The whole tooth-shaped rotating piece 13 is fixed on the telescopic supporting column 7 through a rotating shaft, and the tooth-shaped rotating piece 13 can rotate on the telescopic supporting column 7 clockwise or anticlockwise through the rotating shaft. As another installation method of the tooth-shaped rotating member 13, the bottom of the tooth-shaped rotating member 13 may be configured as a circular base, and a circular concave cavity matched with the circular base is provided on the end surface of the telescopic strut 7, the circular base of the tooth-shaped rotating member 13 is embedded inside the circular concave cavity, and meanwhile, the tooth-shaped rotating member 13 also needs to be capable of rotating clockwise or counterclockwise inside the circular concave cavity.

The end position of the guide groove 14 close to one side of the bottom of the mounting hole 6 is provided with a locking groove 16, and the locking groove 16 is communicated with the guide groove 14. The locking groove 16 extends along the left and right groove walls of the guide groove 14 to the outside, and the left side of the locking groove extends along the groove walls of the guide groove 14 to form a rectangular groove, and the right side of the locking groove extends along the groove walls of the guide groove 14 to form an arc-shaped groove. Meanwhile, the arc-shaped groove edge of the locking groove 16 and the groove wall of the guide groove 14 form a first tip 35, and the side wall of the first tip 35 connected with the arc-shaped groove is an inclined surface, i.e. two side surfaces of the first tip 35 are not perpendicular to each other, but have an included angle smaller than 90 degrees.

Meanwhile, a second pointed end 36 and a third pointed end 37 are formed between the rectangular groove of the locking groove 16 and the groove wall of the guide groove 14, and both side surfaces of the second pointed end 36 and both side surfaces of the third pointed end 37 are perpendicular to each other, as shown in fig. 7 in detail. When the telescopic support 7 is inserted inside the mounting hole 6, the toothed rotating member 13 is located just inside the guide groove 14.

The spring 15 is disposed inside the mounting hole 6, and one end thereof is connected to the telescopic strut 7, and the other end thereof is connected to the bottom of the mounting hole 6. The spring 15 needs to be in a compressed state all the time so that the spring 15 constantly provides a pushing force to the telescopic support 7 moving to the outside of the mounting hole 6.

When the upper line plate 1 and the lower line plate 2 are in a separated state, and the upper line plate 1 and the lower line plate 2 are required to be folded, only the telescopic support 7 needs to be forced to move towards the inside of the mounting hole 6. In the process, the toothed rotating piece 13 can synchronously slide to one side of the locking groove 16 along the groove wall of the guide groove 14 along with the telescopic support column 7, the spring 15 is compressed, and a pushing force for pushing the telescopic support column 7 to the outer side of the mounting hole 6 is continuously generated; when the toothed rotating piece 13 is located inside the locking groove 16, the upper right sharp tooth 33 of the toothed rotating piece 13 continues to be pushed along the inclined surface of the first tip 35 under the interference of the first tip 35 under the pushing of the telescopic support column 7, and the toothed rotating piece 13 rotates counterclockwise, so that the V-shaped gap between the upper right sharp tooth 33 and the lower right sharp tooth 34 is clamped at the first tip 35, thereby preventing the telescopic support column 7 from continuing to move towards the inside of the mounting hole 6. At this moment, the user is required to cancel the external force, after the external force applied to the telescopic support 7 is cancelled, the telescopic support 7 is pushed reversely by the spring 15 under the action of the spring 15, and the V-shaped gap between the upper left sharp tooth 31 and the lower left sharp tooth 32 is pushed to the third tip 37, so that the entire toothed rotating member 13 continues to rotate counterclockwise by a certain angle under the blocking of the third tip 37, and meanwhile, the V-shaped gap between the upper left sharp tooth 31 and the lower left sharp tooth 32 is clamped at the third tip 37, so that the spring 15 is blocked to continuously push the telescopic support 7 to move to the outside of the mounting hole 6, and the telescopic support 7 is locked.

At this time, the upper thread plate 1 and the lower thread plate 2 are folded and fixed together and cannot be separated.

When the upper line plate 1 and the lower line plate 2 are in a closed state and the upper line plate 1 and the lower line plate 2 need to be separated for use, external force to the inside of the mounting hole 6 only needs to be applied to the telescopic support 7 again. It should be noted that when the upper line plate 1 and the lower line plate 2 are in the closed state, a certain gap still needs to be kept between the two to ensure that the telescopic support 7 can be driven to move towards the inner side of the mounting hole 6 under the action of external force.

In the process, the whole toothed rotating member 13 continues to move towards the inside of the mounting hole 6, the spring 15 is compressed, and the long side between the right lower tine 34 and the left lower tine 32 blocks the first tip 35 to make the whole toothed rotating member 13 continue to rotate counterclockwise, so that the V-shaped gap between the left upper tine 31 and the left lower tine 32 is clamped at the second tip 36 to block the telescopic support column 7 from further advancing, and at this time, the user is required to release the external force applied to the telescopic support column 7.

When the external force applied to the telescopic support column 7 is released again, the lower right sharp tooth 34 is pushed to the arc-shaped groove of the locking groove 16 under the action of the spring 15, the lower right sharp tooth 34 is rotated to face the guide groove 14 under the guiding action of the arc-shaped groove, and then the whole toothed rotating piece 13 moves to the outer side of the mounting hole 6 along the groove wall of the guide groove 14 under the action of the spring 15 until the toothed rotating piece 13 moves to the bottom of the guide groove 14 and cannot move any more, so that the upper line board 1 and the lower line board 2 are separated from each other.

At this time, in order to ensure that the upper line board 1 and the lower line board 2 can maintain a good stable state after being separated, the spring 15 still needs to have a certain elastic force at this time, so as to avoid the influence of the looseness between the upper line board 1 and the lower line board 2 on the use effect.

For better implementation, the present embodiment may also provide another set of solution, which is configured as shown in fig. 9, that is, a spring slot 17 is provided on the inner side wall of the mounting hole 6, which is parallel to the telescopic strut 7, the end of the telescopic strut 7 is provided with a strut fixing point 18 corresponding to the position of the spring slot 17, the spring 15 is disposed inside the spring slot 17, one end of which is connected to the strut fixing point 18, and the other end of which is connected to the bottom of the spring slot 17.

In short, when the upper line board 1 and the lower line board 2 are in a closed state, if the upper line board 1 and the lower line board 2 are required to be separated, only the upper line board 1 and the lower line board 2 need to be pressed forcibly and then loosened, and at the moment, the upper line board 1 and the lower line board 2 can be separated and kept in a separated state under the action of the telescopic control assembly.

When the upper line plate 1 and the lower line plate 2 in the separated state need to be folded, the line plate 1 and the lower line plate 2 only need to be squeezed forcibly again and then loosened, and at the moment, the upper line plate 1 and the lower line plate 2 can be folded under the action of the telescopic control assembly and keep the folded state.

The present embodiment differs from embodiment 4 in the following three points: first, the locking groove in the present embodiment is a rectangular locking groove 19, and the number of the rectangular locking grooves 19 is only one, and it is provided on any one side wall of the guide groove 14. The rectangular locking groove 19 has an upper groove edge 38 on the upper end surface and a lower groove edge 39 on the lower end surface, and the end surfaces of the upper groove edge 38 and the lower groove edge 39 are parallel to each other.

Secondly, in order to match the rectangular locking groove 19, the toothed rotating part 13 needs to be arranged on the side close to the rectangular locking groove 19, that is, the toothed rotating part 13 is not arranged on the central axis of the telescopic support post 7, but is positioned at a position deviated from the central axis and close to the rectangular locking groove 19, so as to ensure that the toothed rotating part 13 can rotate in the rectangular locking groove 19.

Thirdly, the spring 15 in this embodiment is always in a tension state, not in a compression state in embodiment 4, so that the spring 15 can continuously provide a tensile force to the telescopic strut 7 in the direction of the inner side of the mounting hole 6.

The structure of the toothed rotating wheel 13 is the same as that of embodiment 4, and is not described herein. In order to change the direction of rotation of the four tooth tips of the toothed rotary part 13, i.e. the upper left tooth tip 31, the lower left tooth tip 32, the upper right tooth tip 33 and the lower right tooth tip 34, during its movement within the guide groove 14, a deflection piece 37 is provided between the opening position of the mounting hole 6 and the opening position of the rectangular locking groove 19, and the deflection piece 37 is located on the central axis of the telescopic support 7.

In order to ensure that the upper board 1 and the lower board 2 are in the closed state and can maintain the closed state in the initial state, the spring 15 is preferably arranged between the bottom of the guide groove 14 and the end of the telescopic strut 7, and the spring 15 needs to be in a stretched state all the time. Namely, one end of the spring 15 is fixedly connected with the bottom of the guide groove 14, the other end of the spring 15 is fixedly connected with the end of the telescopic strut 7, and meanwhile, after the spring 15 is connected, the spring 15 is always in a stretched state, so that the spring 15 continuously provides elastic force for the telescopic strut 7 to move towards the inside of the mounting hole 6, and further, a tensile force for enabling the upper line board 1 and the lower line board 2 to be folded is always kept between the upper line board 1 and the lower line board 2.

When the telescopic support post 7 is inserted into the mounting hole 6, the toothed rotating piece 13 is just inside the guide groove 14, and the toothed rotating piece 13 can slide along the inner wall of the guide groove 14 along with the movement of the telescopic support post 7.

Fig. 10 is a structural diagram illustrating an initial state of the upper line plate 1 and the lower line plate 2 in the present embodiment, in which the spring 15 is always in a stretched state, so that the upper line plate 1 and the lower line plate 2 are always in a closed state and can maintain the closed state. The state of keeping this state means that when there is not enough external force to separate the upper and

lower line plates

1 and 2, the upper and

lower line plates

1 and 2 are kept in the closed state by the urging force of the spring 15 until there is enough external force to separate them.

When the upper line board 1 and the lower line board 2 need to be separated for use, the upper line board 1 and the lower line board 2 can be separated only by using an external force larger than the elastic force of the spring 15, and the process is divided into two steps to be realized.

Firstly, applying separated external force to the upper line board 1 and the lower line board 2, gradually moving the telescopic supporting column 7 to the outer side of the mounting hole 6 under the action of the separated external force, and sliding the toothed rotating piece 13 to the rectangular locking groove 19 in the guide groove 14 synchronously along with the telescopic supporting column 7; when the toothed rotating part 13 slides to the position of the turning block 37, the toothed rotating part 13 rotates clockwise due to the blocking of the turning block 37, so that the turning block 37 is blocked at the position of the V-shaped gap between the left lower tine 32 and the right lower tine 34 to prevent the lower line board 2 from further moving away from the upper line board 1. At this time, the tips of the upper right tines 33 are located in the rectangular locking grooves 19, and the structure is as shown in fig. 11.

Secondly, when the lower plate 2 can no longer be pulled, the external force needs to be released. Under the pulling force of the spring 15, the lower coil plate 2 can move towards the upper coil plate 1 along with the telescopic supporting column 7, and at the moment, the telescopic supporting column 7 can drive the tooth-shaped rotating piece 13 to move to the position of the rectangular locking groove 19. Because the tooth point of the upper right sharp tooth 33 is positioned in the rectangular locking groove 19 and is blocked by the upper groove edge 38 of the rectangular locking groove 19, the V-shaped gap between the upper left sharp tooth 31 and the upper right sharp tooth 33 can be clamped on the upper groove edge 38 and locked, so that the lower line board 2 is prevented from continuously moving towards the upper line board 1, a distance is always kept between the upper line board 1 and the lower line board 2, and the upper line board 1 and the lower line board 2 are kept in a separated state. At this time, the tips of the upper right tines 33 are positioned inside the rectangular locking grooves 19, and the structure thereof is shown in fig. 12.

When the use is finished and the upper line board 1 and the lower line board 2 need to be folded, only two steps are needed to realize the folding.

Firstly, applying separated external force to the upper line board 1 and the lower line board 2, gradually moving the telescopic supporting column 7 to the outer side of the mounting hole 6 under the action of the separated external force, and sliding the tooth-shaped rotating piece 13 to the rectangular locking groove 19 direction in the guide groove 14 synchronously along with the telescopic supporting column 7; when the tooth-shaped rotating piece 13 slides to the position of the turning block 37, due to the blocking of the turning block 37, the tooth-shaped rotating piece 13 rotates clockwise, so that the long sides where the tooth tip of the upper right tine 33 and the lower right tine 34 are located are blocked by the turning block 37 and the lower slot side 39, and the upper line board 1 and the lower line board 2 are limited to be separated continuously by external force, at the moment, the tooth tips of the upper left tine 31 and the upper right tine 33 are located inside the rectangular locking slot 19, and the structure of the tooth-shaped rotating piece is as shown in fig. 13.

Secondly, when the lower plate 2 can no longer be pulled, the external force needs to be released. Under the pulling force of the spring 15, the lower coil plate 2 can move towards the upper coil plate 1 along with the telescopic supporting column 7, and at the moment, the telescopic supporting column 7 can drive the tooth-shaped rotating piece 13 to move to the position of the rectangular locking groove 19 again. Since the tooth tip of the upper left tine 31 is located in the rectangular locking groove 19 and the upper groove edge 38 of the rectangular locking groove 19 is blocked, the entire toothed rotating member 13 continues to rotate clockwise, so as to return to the original state shown in fig. 10, release the locking, and allow the upper line plate 1 and the lower line plate 2 to be folded and maintain the folded state under the action of the spring 15, which is shown in fig. 14.

In short, compared with embodiment 4, the most significant difference is the way of force applied when separating the upper plate 1 and the lower plate 2.

In this embodiment, when the upper line board 1 and the lower line board 2 are in the closed state, if the upper line board 1 and the lower line board 2 need to be separated, a separated external force needs to be applied to the upper line board 1 and the lower line board 2, and then the upper line board 1 and the lower line board 2 are loosened, at this time, the upper line board 1 and the lower line board 2 can be separated under the action of the telescopic control assembly and keep the separated state.

When the upper line plate 1 and the lower line plate 2 in the separated state need to be folded, external force for separating the line plate 1 and the lower line plate 2 only needs to be applied again, and then the external force is released, and at the moment, the upper line plate 1 and the lower line plate 2 can be folded under the action of the telescopic control assembly and keep the folded state.

Example 6

This embodiment is a specific description of a fifth structure of the telescoping control assembly based on embodiment 1, and the structure of the telescoping control assembly described in this embodiment is shown in fig. 15 and 16. Meanwhile, in order to facilitate the illustration of the drawings, the plug 4 and the wires in the drawings are omitted in this embodiment, and the position relationship and the connection relationship between the plug 4 and the wires are completely the same as those in the previous embodiment, and are not described herein again.

The flexible control assembly of this embodiment is including setting up on telescopic strut 7 quantity for more than one elastic fixation head 20, set up on the terminal surface of wiring board 1 and with mounting hole 6 looks through's fixed orifices 21, set up on wiring board 1 and with this fixed orifices 21 assorted elastic press key 22 to and set up inside mounting hole 6 and provide the spring 15 constitution towards the outside thrust of mounting hole 6 for telescopic strut 7.

In this embodiment, the telescopic support 7 is provided with a plurality of bullet holes, and the elastic fixing heads 20 are installed in the bullet holes. To ensure the use effect, the warhead holes need to be uniformly distributed along the central axis of the telescopic support 7. Meanwhile, each elastic fixing head 20 is composed of a bullet and a small spring 40, the bullet is embedded in the bullet hole, and the small spring 40 is located between the bottom of the bullet hole and the bullet and continuously provides an outward elastic force to the bullet.

When the telescopic support 7 is inserted into the mounting hole 6, all the elastic fixing heads 20 except the elastic fixing head 20 which is positioned just corresponding to the fixing hole 21 are compressed in the corresponding bullet holes by the hole walls of the mounting hole 6. And the bullet of the elastic fixing head 20, which is positioned right corresponding to the fixing hole 21, is pressed inside the fixing hole 21 by the small spring 40, thereby locking the distance between the upper line plate 1 and the lower line plate 2.

When the upper line board 1 and the lower line board 2 need to be separated for use, only the elastic key 22 needs to be pressed forcibly, the elastic key 22 can extrude the bullet of the elastic fixing head 20 out of the fixing hole 21, at the moment, the spring 15 can push the telescopic support 7 to move towards the outer side of the mounting hole 6, and as the bullets of other elastic fixing heads 20 are always in a supported state, as long as the bullet position of the next elastic fixing head 20 corresponds to the position of the fixing hole 21, the bullet of the elastic fixing head 20 can be pushed by the small spring 40 to be embedded into the fixing hole 21, so that the purpose of locking the distance between the upper line board 1 and the lower line board 2 is achieved.

On the contrary, when the upper line plate 1 and the lower line plate 2 need to be folded, only the upper line plate 1 and the lower line plate 2 need to be pressed by force, the working principle is the same as that of the prior art, and the description is omitted.

Example 7

This embodiment is a specific description of a sixth structure of the telescopic control assembly based on embodiment 1, and the structure of the telescopic control assembly described in this embodiment is shown in fig. 17 to 19.

The telescoping control assembly of the present embodiment is composed of a ratchet wheel 23, a fixed ratchet wheel 24, a movable ratchet wheel 25, a spring 15 and a balance spring 27.

A cylindrical cavity structure is arranged inside the telescopic support 7, and an opening is formed in the cavity structure at the end face of the telescopic support 7. The ratchet wheel 23 is provided at the distal end opening position of the telescopic strut 7.

The movable ratchet wheel 25 is constructed as shown in fig. 18, and is provided with a guide rod 26, the diameter of the guide rod 26 is slightly smaller than the inner diameter of the cavity of the telescopic support 7, so that the guide rod 26 of the movable ratchet wheel 25 can be inserted into the cavity of the telescopic support 7 and can rotate in the cavity.

The fixed ratchet wheel 24 is composed of four groups of ratchet column bars which are arranged on the hole wall of the mounting hole 6 and are uniformly distributed along the hole wall, a ratchet is arranged at the end of each group of ratchet column bars, and a ratchet groove for the ratchet gear 23 and the movable ratchet wheel 25 to be embedded and slide is formed between the two adjacent groups of ratchet column bars. The ratchet wheel teeth 23 and the movable ratchet wheel 25 are matched with the fixed ratchet wheel 24.

The spring 15 is fixedly installed inside the mounting hole 6 and between the movable ratchet wheel 25 and the bottom of the mounting hole 6. The spring 15 needs to be in a compressed state all the time so that the spring 15 can continuously provide the telescopic support 7 with a pushing force pushing it towards the outside of the mounting hole 6.

The balance spring 27 is also disposed inside the mounting hole 6 between the ratchet gear 23 of the telescopic support 7 and the open end of the mounting hole 6. The counter spring 27 also needs to be in a compressed state at all times so that it can constantly provide a pushing force to the telescopic strut 7 that pushes the telescopic strut 7 towards the inside of the mounting hole 6.

To ensure that the movable ratchet wheel 25 automatically pushes the telescopic support 7 out of the mounting hole 6 when it is unlocked, the spring force of the spring 15 is greater than the spring force of the counter spring 27.

When the upper line plate 1 and the lower line plate 2 are in a closed state, the movable ratchet wheel 25 is clamped on the ratchet teeth of the fixed ratchet wheel 24, the spring 15 is compressed by the driven ratchet wheel 25, and the ratchet gear 23 on the telescopic support 7 is pushed by the elastic force of the balance spring 27 to be at the ratchet teeth position of the fixed ratchet wheel 24.

When the upper line plate 1 and the lower line plate 2 need to be separated for use, the upper line plate 1 and the lower line plate 2 need to be pressed by force, the telescopic strut 7 moves towards the inner side of the mounting hole 6 under the driving of the external force, and the ratchet wheel 23 moves synchronously along with the telescopic strut 7, so that the movable ratchet wheel 25 is pushed to be separated from the ratchet of the fixed ratchet wheel 24. At this time, the movable ratchet wheel 25 rotates a certain angle under the interaction of the elastic force of the spring 15 and the ratchet teeth, so that the movable ratchet wheel 25 can enter the ratchet groove of the fixed ratchet wheel 24 and be pushed to the lowermost end of the ratchet groove of the fixed ratchet wheel 24 under the elastic force of the spring 15. When the movable ratchet wheel 25 is pushed, the ratchet wheel 23 on the telescopic strut 7 is synchronously pushed to the bottom of the ratchet groove, so that the telescopic strut 7 moves towards the outer side of the mounting hole 6, and finally the purpose of separating the upper line plate 1 from the lower line plate 2 is achieved.

When the separated upper line plate 1 and the separated lower line plate 2 need to be folded, external force needs to be continuously applied to the upper line plate 1 and the lower line plate 2, so that the telescopic support 7 moves towards the inner side of the mounting hole 6 under the driving of the external force. At this time, the ratchet gear 23 moves synchronously with the telescopic support 7, thereby pushing the movable ratchet 25 to move along the ratchet groove to be located at the ratchet teeth of the fixed ratchet 24. Under the interaction of the elastic force of the spring 15 and the ratchet teeth, the movable ratchet wheel 25 will continue to rotate a certain angle, so that the movable ratchet wheel 25 is disengaged from the ratchet groove and is stuck on the ratchet teeth of the fixed ratchet wheel 24, and the stop ratchet wheel 25 will not be prevented from returning to the ratchet groove under the action of the spring 15.

At this time, because the movable ratchet wheel 25 is locked, the balance spring 27 is not blocked by the spring 15, and the balance spring 27 pushes the telescopic support 7 to move towards the inner side of the mounting hole 6, so as to drive the lower line board 2 to approach the upper line board 1, and finally achieve the purpose of folding the upper line board 1 and the lower line board 2.

Example 8

In this embodiment, the power guide rail is added on the basis of embodiments 1 to 7, so as to change the connection mode between the plug 4 and the zero line conducting strip 45, the live line conducting strip 46 and the ground conducting strip 47 inside the upper line plate 1 and the lower line plate 2. The structure described in this embodiment can exist and be used simultaneously with any of the structures of embodiments 1 to 7, and only the manner of connecting the wires of the plug 4 to the upper line board 1 and the lower line board 2 simultaneously is changed to be able to connect only to the upper line board 1 or the lower line board 2.

As shown in fig. 20, the power rail is composed of a rail housing 41 having an open end, and a neutral rail 42, a live rail 43, and a ground rail 44 which are provided inside the rail housing 41 and insulated from each other.

One end of the guide rail housing 41 is arranged inside the lower line board 2 and fixedly connected with the lower line board, and the other end of the guide rail housing is inserted into the mounting hole 6. When the connection is made, the ends of the neutral conductor conducting strip 45, the live conductor conducting strip 46 and the ground conductor conducting strip 47 inside the upper board 1 are respectively inserted into the neutral conductor guide rail 42, the live conductor guide rail 43 and the ground conductor guide rail 44 which are positioned inside the upper board 1 and correspond to the neutral conductor conducting strip, the live conductor conducting strip 46 and the ground conductor conducting strip.

Accordingly, the ends of the neutral conductor tab 45, the live conductor tab 46 and the ground conductor tab 47 on the lower board 2 are inserted into the respective neutral conductor rail 42, the live conductor rail 43 and the ground conductor rail 44 which are located inside the lower board 2 and correspond thereto.

Because the power guide rail inside the mounting hole 6 of the upper line board 1 is not fixedly connected with the upper line board 1, when the upper line board 1 and the lower line board 2 are folded and separated, the ends of the zero line conducting strip 45, the live line conducting strip 46 and the ground line conducting strip 47 inside the upper line board 1 slide along the inner walls of the tracks of the zero line guide rail 42, the live line guide rail 43 and the ground line guide rail 44 which are located inside the mounting hole 6 and correspond to the mounting hole, so that the socket 3 inside the upper line board 1 is always in a conducting state.

At this time, the wires of the plug 4 only need to be correspondingly connected with the zero line guide rail 42, the live line guide rail 43 and the ground line guide rail 44 in the power guide rail inside the upper line board 1 or the lower line board 2.

As described above, the utility model discloses alright fine realization.
