[0002] An energy storage power supply is a device that can store electrical energy and release it when needed. It takes a storage battery as the core and is equipped with a DC power supply circuit and a control circuit to achieve flexible scheduling and emergency guarantee of electrical energy. In order to improve the effective usage time and storage capacity of the energy storage power supply, multiple energy storage batteries need to be operated in parallel in a network;

[0003] During the parallel connection operation of energy storage power supplies, in addition to the network parallel connection of multiple energy storage batteries, physical connection between adjacent energy storage battery boxes is also required. The physical connection of the energy storage battery boxes needs to be completed before the network parallel connection and fixed through reliable physical connection to ensure the stable connection of the parallel connection of energy storage power supplies.

[0004] After searching for the invention patent with the patent number CN118610685B, it discloses a stacked household energy storage battery, including a battery seat, and multiple battery bodies are sequentially stacked on the top of the battery seat. The present invention completes the synchronous limitation of adjacent battery bodies through a synchronous limitation mechanism, making the overall stacking convenient and fast, improving the space utilization rate of the energy storage battery and reducing the floor area.

In addition, it meets the usage purpose of separate pulling and disassembling, ensuring the flexibility and convenience of disassembly;

[0028] 1. The assembly board frame is rotatably connected to the connection seat in the energy storage power supply body through the auxiliary of the shaft column, so that the assembly board frame is arranged in a rotatable structure on the energy storage power supply body. The connection seat in the energy storage power supply body is in an inclined state at its corner on its diagonal line. By flipping the assembly board frame, its position is swapped on the adjacent two casing walls of the energy storage power supply body. According to the parallel connection assembly requirements, the assembly board frame is flipped and swapped to the corresponding side casing wall of the energy storage power supply body for docking with the adjacent energy storage power supply body, realizing the free adjustment and conversion between vertical stacking and horizontal stacking, that is, meeting the usage purposes of different morphological combination assemblies such as vertical stacking parallel connection assembly or horizontal stacking parallel connection assembly, improving the applicable range, and being applicable to the placement and usage requirements of different sites;

[0030] 2. After the driving member drives the transmission rod to rotate synchronously, through the meshing action between the second gear part and the second rack part, the first linkage frame and the second linkage frame are driven to slide in opposite directions. When the first linkage frame and the second linkage frame slide outwards away from each other, through the meshing action between the first rack part and the first gear part, the first claw and the second claw both flip and fold, respectively losing engagement with the two locking grooves, realizing the convenient unlocking operation.

Different from the existing ones that need to be disassembled in sequence, it can realize interval disassembly operation, ensuring the flexibility and convenience of disassembly and being easy for later maintenance;

[0031] Furthermore, when the first linkage frame and the second linkage frame slide inwardly close to each other, through the pressing fit between the blocking portion and the corner block portion, the first claw and the second claw are blocked and restricted, and respectively maintain the engagement with the two locking grooves, so as to realize the reinforcement and locking after the parallel connection and assembly, and improve the stability effect after the parallel connection and assembly.

Detailed implementation mode

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0044] Embodiment 1:

[0045] The present invention provides a technical solution: an energy storage power supply parallel connection device with a self-locking structure, which is used to solve the problem that the free adjustment and conversion between vertical stacking and horizontal stacking cannot be realized, and the use purpose of different form combinations and assembly cannot be satisfied, affecting the scope of application. The assembling plate frame 2 forms a flipping structure on the energy storage power supply body 1. By flipping the assembling plate frame 2, the position can be switched on the adjacent two casing walls of the energy storage power supply body 1. The assembling plate frame 2 is provided with a locking mechanism 3, and the longitudinal stacking and parallel connection assembly or the horizontal stacking and parallel connection assembly between two adjacent energy storage power supply bodies 1 are carried out in cooperation with the locking mechanism 3.

[0046] This technical solution: Please refer to Figures 1 - 5 , an energy storage power supply parallel connection device with a self-locking structure, includes an energy storage power supply body 1. A control module is arranged in the front end body of the energy storage power supply body 1. The control modules in two adjacent energy storage power supply bodies 1 establish a circuit connection through cables for network parallel connection between them (where the connection methods of the control module and the control module are both prior arts and are not described in the specification drawings). A heat dissipation module for cooling the body is arranged in the rear end body of the energy storage power supply body 1 (where the heat dissipation module is also a prior art and is not described in the specification drawings). Integrated connection seats are arranged at the upper right corner and the lower left corner of the energy storage power supply body 1. The connection seats are arranged at a forty-five-degree inclination angle at their corners, that is, the connection seat located at the upper right corner and the connection seat located at the lower left corner are both on the diagonal line of the energy storage power supply body 1;

[0047] It further includes an assembled panel frame 2, the specification size of the assembled panel frame 2 is adapted to the specification size of one side casing wall of the energy storage power supply body 1, and a locking mechanism 3 for locking between two adjacent energy storage power supply bodies 1 is arranged thereon. The locking mechanism 3 is symmetrically arranged front and back with respect to the horizontal central axis of the assembled panel frame 2. The assembled panel frame 2 forms a flipping structure on the energy storage power supply body 1 with the assistance of the connecting seat central shaft column, and its flipping can perform position swapping on the adjacent two side casing walls of the energy storage power supply body 1, and it cooperates with the locking mechanism 3 to operate the longitudinal stacking and parallel assembly or the transverse stacking and parallel assembly between two adjacent energy storage power supply bodies 1.

[0048] Specifically, in this technical solution, when performing the flipping and swapping operation of the position of the assembled panel frame 2, according to Figure 1 , Figure 3 and Figure 4 As shown, a shaft column is rotatably connected to the connecting seat in the energy storage power supply body 1, and the front and rear ends of the shaft column respectively penetrate through and are inserted outside the front and rear sides of the connecting seat. Since an open groove is provided on the side of the assembled panel frame 2 close to the connecting seat in the energy storage power supply body 1, after the assembled panel frame 2 is placed, the connecting seat in the energy storage power supply body 1 is movably clamped in the groove therein. Also, since the two ends of the shaft column of the connecting seat in the energy storage power supply body 1 are respectively inserted and fixedly connected to the two side walls of the groove in the assembled panel frame 2 through bolts, according to the parallel assembly requirement, with the assistance of the connecting seat central shaft column, the assembled panel frame 2 is flipped on the energy storage power supply body 1 and flipped and fitted to the corresponding side casing wall in the energy storage power supply body 1, so that the assembled panel frame 2 is horizontally arranged on the corresponding side casing wall in the energy storage power supply body 1 after flipping, and the position swapping of the assembled panel frame 2 is completed;

[0049] Since a friction ring is installed at the rotational connection of the connecting seat in the energy storage power supply body 1 and the connecting seat central shaft column, through the friction damping effect, it prevents the connecting seat central shaft column from rotating randomly thereon, that is, it prevents the assembled panel frame 2 from flipping randomly on the energy storage power supply body 1, and performs preliminary limiting after the flipping and swapping of the assembled panel frame 2;

[0050] Since limiting grooves 4 are provided in the middle of the upper, lower, left and right four side casing walls of the energy storage power supply body 1, the longitudinal section of the limiting groove 4 is in a semi-circular structural state. Also, since a positioning convex block 5 with an integrated structure is arranged in the middle of the assembled panel frame 2, the positioning convex block 5 is symmetrically arranged up and down with respect to the horizontal central axis of the assembled panel frame 2, and its longitudinal section is also in a semi-circular structural state and is adapted to the limiting groove 4. When the assembled panel frame 2 is flipped and swapped and fitted to the corresponding side casing wall in the energy storage power supply body 1, the positioning convex block 5 is clamped into the limiting groove 4. After the two are clamped, the assembled panel frame 2 is restricted to prevent the phenomenon that the assembled panel frame 2 slides left and right after being butted with the casing wall in the energy storage power supply body 1.

[0051] Specifically, in this technical solution, when the assembled panel frame 2 is flipped and adjusted and then locked by the locking mechanism 3, according to Figure 1 , Figure 3 , Figure 4 and Figure 5 shown, the locking mechanism 3 includes a first claw 6 away from the flipping center of the assembled panel frame 2 and a second claw 7 close to the flipping center of the assembled panel frame 2, and both the first claw 6 and the second claw 7 are symmetrically arranged up and down with respect to the horizontal central axis of the assembled panel frame 2. Since locking grooves 9 are provided on the housing walls on the upper, lower, left, and right sides of the energy storage power supply body 1, and the locking grooves 9 are symmetrically arranged front and back with respect to the horizontal central axis of the energy storage power supply body 1, corresponding to the front and back two locking mechanisms 3 respectively. Also, since the locking groove 9 away from the flipping center of the assembled panel frame 2 is adapted to the first claw 6 and is arranged in a corresponding state, and the locking groove 9 close to the flipping center of the assembled panel frame 2 is adapted to the second claw 7 and is arranged in a corresponding state. When the assembled panel frame 2 is flipped and adjusted, the first claw 6 and the second claw 7 on one side of the assembled panel frame 2 are respectively docked with the two locking grooves 9 on the corresponding side housing wall of the energy storage power supply body 1;

[0052] Since a cavity is provided on the plate body of the assembled panel frame 2 and is communicated with its frame cavity, the first claw 6 is arranged in an "L" - shaped structure, divided into a longitudinal claw body and a transverse claw body. The end of the longitudinal claw body of the first claw 6 is inserted and fixedly connected with a shaft column through a bolt. The front and rear ends of the shaft column respectively extend towards the front and rear outer sides of the first claw 6, and bearings are fixedly sleeved on both ends of the shaft column respectively. After the first claw 6 is installed, it is in a vertical state. The longitudinal claw body is movably inserted into the cavity of the assembled panel frame 2, and the transverse claw body is placed outside the cavity, and both ends of the shaft column together with the bearings are clamped on the front and rear side walls of the cavity. Also, since the locking groove 9 is arranged in an "L" - shaped structure, divided into a longitudinal groove path and a transverse groove path. When the first claw 6 is docked with the locking groove 9 away from the flipping center of the assembled panel frame 2, an inclined side wall is provided at the end of the transverse claw body of the first claw 6. The first claw 6 is restricted, and with the assistance of the inclined side wall, the first claw 6 is pushed and flipped on the assembled panel frame 2;

[0053] Since spring chambers are provided on both the front and rear sides of the end of the longitudinal claw body in the first claw 6, a torsion spring 8 for resetting is installed at the flipping connection between the first claw 6 and the assembly plate frame 2. The torsion springs 8 are symmetrically arranged front and rear. After being placed, the torsion springs 8 in the first claw 6 are movably sleeved on the central shaft of the first claw 6 and placed in the spring chambers in the first claw 6. One end of each torsion spring 8 is clamped on the wall of the spring chamber, and the other end is clamped on the wall of the cavity in the assembly plate frame 2. After the first claw 6 is pushed and flipped, the torsion spring 8 on it is elastically deformed under force. When the first claw 6 is docked with the locking groove 9 away from the flipping center of the assembly plate frame 2, the first claw 6 is unrestricted. Using the elastic deformation of the torsion spring 8 on it for resetting, the first claw 6 performs a reset flip on the assembly plate frame 2, and the first claw 6 is automatically snapped and connected to the locking groove 9 away from the flipping center of the assembly plate frame 2, that is, the transverse claw body in the first claw 6 is snapped and hooked in the transverse groove in the current locking groove 9;

[0054] Since the second claw 7 and the first claw 6 have the same specifications, dimensions, and structural shapes, and are also divided into longitudinal claw bodies and transverse claw bodies, the placement method of the second claw 7 on the assembly plate frame 2 is the same as that of the first claw 6 on the assembly plate frame 2. Also, since a torsion spring 8 for resetting is installed at the flipping connection between the second claw 7 and the assembly plate frame 2, the placement method of the torsion spring 8 in the second claw 7 is the same as that of the torsion spring 8 in the first claw 6. When the second claw 7 is docked with the locking groove 9 close to the flipping center of the assembly plate frame 2, an inclined side wall is provided at the end of the transverse claw body in the second claw 7. The second claw 7 is restricted, and with the assistance of the inclined side wall, the second claw 7 is pushed and flipped on the assembly plate frame 2. After the second claw 7 is pushed and flipped, the torsion spring 8 on it is elastically deformed under force. When the second claw 7 is docked with the locking groove 9 close to the flipping center of the assembly plate frame 2, the second claw 7 is unrestricted. Using the elastic deformation of the torsion spring 8 on it for resetting, the second claw 7 performs a reset flip on the assembly plate frame 2, and the second claw 7 is automatically snapped and connected to the locking groove 9 close to the flipping center of the assembly plate frame 2, that is, the transverse claw body in the second claw 7 is snapped and hooked in the transverse groove in the current locking groove 9;

[0055] Since the flipping direction of the second claw 7 is opposite to that of the first claw 6, and they are arranged in opposite orientations, through the cooperation between the first claw 6 and the second claw 7, and in combination with the snapping effect between the positioning convex block 5 and the limiting groove 4, the flipped and swapped assembly plate frame 2 is automatically locked.

[0056] Specifically, in this technical solution, when the assembly plate frame 2 cooperates with the locking mechanism 3 for parallel assembly between two adjacent energy storage power supply bodies 1, according to Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, according to the above, since the first clamping claw 6 and the second clamping claw 7 are symmetrically arranged about the horizontal center axis of the assembly plate frame 2, locking grooves 9 are opened on the upper and lower left and right four side casing walls of the energy storage power supply body 1. The locking groove 9 away from the flipping center of the assembly plate frame 2 is adapted to the first clamping claw 6 and is arranged in a corresponding state, and the locking groove 9 close to the flipping center of the assembly plate frame 2 is adapted to the second clamping claw 7 and is arranged in a corresponding state. The two locking grooves 9 on the casing wall on the corresponding side of the adjacent energy storage power supply body 1 are respectively docked and engaged with the first clamping claw 6 and the second clamping claw 7 on the other side of the assembly plate frame 2 to complete the automatic locking of the two adjacent energy storage power supply bodies 1 after parallel assembly.

[0057] Embodiment 2:

[0058] The present invention is based on the first embodiment. Figures 6 - 10 The technical solution shown in the figure can be used to deal with the problem that when disassembling the energy storage power supply after parallel assembly, the existing disassembly method is limited by the connection method and can only be disassembled in sequence, and it is impossible to achieve separate disassembly at intervals, and the operation is not convenient enough. The linkage component 10 is symmetrically arranged front and back about the horizontal central axis of the assembly plate frame 2, corresponding to the front and rear two locking mechanisms 3 respectively. The locking mechanism 3 is flipped and folded on the assembly plate frame 2 by operating the linkage component 10, and folded and stored in the groove cavity of the assembly plate frame 2. After the locking effect of the locking mechanism 3 is released, the energy storage power supply body 1 and the assembly plate frame 2 are combined to form a regular block body, which can be pulled out and disassembled individually, and meets the purpose of interval disassembly.

[0059] Specifically, in the technical solution, a driving assembly 16 for operating the sliding of the first linkage frame 11 and the second linkage frame 12 is provided at the joint of the first linkage frame 11 and the second linkage frame 12. The driving assembly 16 is placed in the middle of the frame cavity of the assembly plate frame 2 and is used for synchronously driving the front and rear linkage assemblies 10. When the driving assembly 16 drives the linkage assembly 10, according to Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a groove cavity is opened in the middle of the front side wall of the assembly plate frame 2, and the cross section of the driving member 20 is arranged in a "convex"-shaped structure, which is divided into two parts, a wide part and a narrow part. After the driving member 20 is placed, the wide part is movably clamped in the groove cavity of the middle front side wall of the assembly plate frame 2, and the narrow part movably penetrates through the front side wall of the assembly plate frame 2 and extends outward, and the front end of the narrow part is clamped and fixedly connected with a turning handle by bolts, and the turning handle of the driving member 20 is manually screwed to make the driving member 20 rotate on the front side wall of the assembly plate frame 2;

[0060] Since bearings are fixedly clamped at both the front and rear sections of the rod body in the transmission rod 19, after being installed, it is inserted into the middle of the assembled plate frame 2 together with the bearings and is movable. The front end rod body thereof penetrates through the middle of the spline column 28 and extends forward into the groove cavity on the front side wall of the assembled plate frame 2. Also, since the front end rod body of the transmission rod 19 is arranged in a square rod-shaped structure, a square pipe groove is provided at the center position of the narrow part in the driving member 20, and the square pipe groove is adapted to the square rod end of the transmission rod 19. Moreover, since the driving member 20 is arranged on the same central axis as the transmission rod 19 after installation, the square rod end of the transmission rod 19 is movably inserted and clamped in the square pipe groove of the driving member 20. After the driving member 20 is driven to rotate, through the engagement between the square rod end in the transmission rod 19 and the square pipe groove in the driving member 20, the transmission rod 19 and the driving member 20 form a synchronous rotation structure, and the transmission rod 19 rotates in the middle of the assembled plate frame 2;

[0061] Since the first annular groove 25 is opened in the groove cavity on the front side wall of the assembled plate frame 2, the longitudinal section of the groove cavity is in a semi-circular arc structure and is adapted to the hemispherical end in the positioning pin 23, and it is concentric with the driving member 20. Also, since a positioning pin 23 is provided at the connection between the driving member 20 and the energy storage power supply body 1, the positioning pin 23 is symmetrically arranged about the central axis of the wide part in the driving member 20, and the hemispherical end thereof is engaged and connected with the first annular groove 25. Through the engagement between the positioning pin 23 and the first annular groove 25, the driving member 20 is movably positioned, so that the spline groove 27 in the driving member 20 does not contact the spline column 28. When the driving member 20 is driven to rotate, the positioning pin 23 slides along the first annular groove 25 without affecting the rotation of the driving member 20;

[0062] Since the front and rear sections of the transmission rod 19 are both provided with an integrated second gear portion 21, the front and rear second gear portions 21 correspond to the front and rear linkage components 10 respectively, the second gear portion 21 is placed at the joint between the inner end of the first linkage frame 11 and the inner end of the second linkage frame 12, and is placed in the middle position of the second rack portion 22. Since one end of the first linkage frame 11 close to the second linkage frame 12 is the inner end, and the other end is the outer end, the second linkage frame 12 and the first linkage frame 11 have the same structural shape and specification size, and are also divided into an inner end and an outer end. The second rack portion 22 is an integrated structure and is arranged at the first linkage frame 11. The inner end of a linkage frame 11 is meshed with the upper side of the second gear portion 21, and the second rack portion 22 is arranged at the inner end of the second linkage frame 12 in an integrated structure, and is meshed with the lower side of the second gear portion 21. Since the inner end of the first linkage frame 11 is bent, the inner end of the first linkage frame 11 and the inner end of the second linkage frame 12 are connected to each other in an up-and-down offset state. After the transmission rod 19 is driven to rotate, the second gear portion 21 and the transmission rod 19 constitute a synchronous rotation structure, and the meshing action between the second gear portion 21 and the second rack portion 22 drives the first linkage frame 11 and the second linkage frame 12 to slide in opposite directions.

[0063] Specifically, in the technical solution, the linkage assembly 10 includes a first linkage frame 11 for driving the first claw 6 alone and a second linkage frame 12 for driving the second claw 7 alone. When the locking mechanism 3 is flipped and folded by the linkage assembly 10 in the frame cavity of the assembled plate frame 2, according to Figure 6 and Figure 8 As shown, since the first linkage frame 11 is arranged in an active state and is stuck in the frame cavity of the assembly plate frame 2 after being arranged, the arrangement method of the second linkage frame 12 on the assembly plate frame 2 is the same as the arrangement method of the first linkage frame 11 on the assembly plate frame 2, and since a spring compartment is provided at the outward end of the first linkage frame 11, a return spring member 13 is installed at the sliding connection between the first linkage frame 11 and the assembly plate frame 2 and the sliding connection between the second linkage frame 12 and the assembly plate frame 2. Both ends of the return spring member 13 are provided with end blocks of an integrated structure, which are arranged symmetrically front and back. The movable plug is arranged in the spring bin of the first linkage frame 11, and one end block thereof is fixedly connected to the spring bin wall by bolts, and the other end block thereof is fixedly connected to the frame cavity wall of the assembly plate frame 2 by bolts. The arrangement mode of the return spring member 13 in the second linkage frame 12 is the same as the arrangement mode of the return spring member 13 in the first linkage frame 11. The first linkage frame 11 and the second linkage frame 12 are driven to slide in opposite directions in the frame cavity of the assembly plate frame 2, that is, the two slide away from each other and outward, so that the return spring member 13 in the first linkage frame 11 and the return spring member 13 in the second linkage frame 12 are squeezed and elastically deformed;

[0064] Since the first linkage frame 11 is placed between the upper and lower first clamping claws 6 after installation, a first rack portion 14 with an integrated structure is provided in the middle of the frame body of the first linkage frame 11. The first rack portion 14 is symmetrically arranged up and down about its horizontal central axis and corresponds to the upper and lower first clamping claws 6 respectively. Also, since a first gear portion 17 with an integrated structure is provided at the middle position of the end of the longitudinal claw body in the first clamping claw 6, and its center coincides with the flipping center of the first clamping claw 6. Moreover, since the specifications and dimensions of the tooth blocks in the first rack portion 14 are the same as those of the tooth blocks in the second rack portion 22, when the first linkage frame 11 slides outwards, the first rack portion 14 thereon is connected to the first gear portion 17 in the first clamping claw 6 in a meshing manner. Through the meshing action of the two, the first clamping claw 6 is flipped and folded, and the first clamping claw 6 is received in the cavity of the assembly plate frame 2 after being flipped and folded;

[0065] Since the second linkage frame 12 is placed between the upper and lower second clamping claws 7 after installation, a first rack portion 14 with an integrated structure is provided in the middle of the frame body of the second linkage frame 12. The first rack portion 14 is symmetrically arranged up and down about its horizontal central axis and corresponds to the upper and lower second clamping claws 7 respectively. Also, since a first gear portion 17 with an integrated structure is provided at the middle position of the end of the longitudinal claw body in the second clamping claw 7, and the installation method of the first gear portion 17 in the second clamping claw 7 is the same as that of the first gear portion 17 in the first clamping claw 6. When the second linkage frame 12 slides outwards, the first rack portion 14 thereon is connected to the first gear portion 17 in the second clamping claw 7 in a meshing manner. Through the meshing action of the two, the second clamping claw 7 is flipped and folded, and the second clamping claw 7 is received in the cavity of the assembly plate frame 2 after being flipped and folded;

[0066] Since the longitudinal groove in the locking groove 9 is arranged in an arc structure, the locking groove 9 away from the flipping center of the assembly plate frame 2 corresponds to the first clamping claw 6, and the center of the arc of the longitudinal groove coincides with the flipping center of the first clamping claw 6, which does not affect the flipping and folding of the first clamping claw 6. The locking groove 9 close to the flipping center of the assembly plate frame 2 corresponds to the second clamping claw 7, and the center of the arc of the longitudinal groove coincides with the flipping center of the second clamping claw 7, which does not affect the flipping and folding of the second clamping claw 7;

[0067] Since the distance between the two corner blocks 18 is greater than the width of the first rack portion 14, that is, when the first rack portion 14 meshes with the first gear portion 17, it is not blocked by the corner blocks 18. In addition, the first rack portion 14 will not affect the flipping corner blocks 18 either;

[0068] In addition, the first linkage frame 11 is assisted by the reset spring member 13 to be arranged in a movable positioning state, and the second linkage frame 12 is assisted by the reset spring member 13 to be arranged in a movable positioning state. A gap is reserved between the first rack portion 14 and the blocking portion 15. In the initial state, the first pawl 6 or the second pawl 7 is placed in the gap therebetween, without affecting the flipping movement of the first pawl 6 or the second pawl 7.

[0069] Specifically, in this technical solution, when performing the separate disassembly operation of the energy storage power supply body 1, according to Figure 6 and Figure 8 As shown, based on the above, after the first pawl 6 and the second pawl 7 are flipped and folded, the engagement and locking with the two locking grooves 9 are released, that is, the locking between the energy storage power supply body 1 and the assembly plate frame 2 is released. Since a rotatable handle is movably arranged on the front side casing of the energy storage power supply body 1, the energy storage power supply body 1 is lifted through the handle. Also, since both the front and rear ends of the limiting groove 4 are arranged in an open state, after the energy storage power supply body 1 is lifted, the positioning convex block 5 can slide out through the open portion at the end of the limiting groove 4, completing the separate disassembly operation of the energy storage power supply body 1.

[0070] Specifically, in this technical solution, when the interlocking assembly 10 in the frame cavity of the assembly plate frame 2 is used to block and limit the locking mechanism 3, according to Figure 6 and Figure 7 As shown, based on the above, manually reverse-rotate the turning handle in the driving member 20, so that the driving member 20 rotates reversely on the front side wall of the assembly plate frame 2, and the transmission rod 19 rotates reversely and synchronously in the middle of the assembly plate frame 2. Through the meshing action between the second gear portion 21 and the second rack portion 22, the first linkage frame 11 and the second linkage frame 12 are driven to slide in opposite directions, that is, both of them slide inwards close to each other, causing the reset spring members 13 in the first linkage frame 11 and the reset spring members 13 in the second linkage frame 12 to be pulled and elastically deformed;

[0071] Since the first linkage frame 11 is arranged between the upper and lower first pawls 6 after being installed, the outer end of the first linkage frame 11 is convexly provided with an integrated blocking portion 15, and the blocking portion 15 is symmetrically arranged up and down about its horizontal central axis, corresponding to the upper and lower first pawls 6 respectively. Also, since the front and rear positions of the end of the longitudinal claw body in the first pawl 6 are provided with integrated corner block portions 18, after the corner block portions 18 in the first pawl 6 are installed, they are perpendicular to the longitudinal claw body in the first pawl 6, and their lower side walls are arranged in parallel with the blocking portion 15. When the first linkage frame 11 slides inwards, the blocking portion 15 on it is connected to the corner block portion 18 in the first pawl 6 in a pressing manner. Through the pressing cooperation between the two, the first pawl 6 is blocked and limited, and the first pawl 6 engaged in the locking groove 9 is further locked;

[0072] Since the second linkage 12 is disposed between the upper and lower second jaws 7, a blocking portion 15 with an integrated structure is protrudingly provided at the outer end of the second linkage 12. The blocking portion 15 in the second linkage 12 is symmetrically arranged up and down about its horizontal central axis, corresponding to the upper and lower second jaws 7 respectively. Also, since corner block portions 18 with an integrated structure are provided at the front and rear positions of the end of the longitudinal jaw body in the second jaw 7, and the corner block portion 18 in the first jaw 6 is arranged in the same way as the corner block portion 18 in the second jaw 7. When the second linkage 12 slides inward, the blocking portion 15 thereon is connected to the corner block portion 18 in the second jaw 7 in a pressing manner. Through the pressing fit of the two, the second jaw 7 is blocked and limited, and the second jaw 7 clamped in the locking groove 9 is further locked;

[0073] Since the cross-section of the blocking portion 15 is arranged in a "U" - shaped structure, the width dimension of the first gear portion 17 is smaller than the width dimension of the "U" - shaped cavity in the blocking portion 15. When the corner block portion 18 is in pressing contact with the blocking portion 15, the first gear portion 17 is placed in the "U" - shaped cavity of the blocking portion 15 and will not cause obstruction.

[0074] Specifically, in this technical solution, when locking the first linkage 11 and the second linkage 12 after sliding, according to Figure 7 、 Figure 8 and Figure 10 As shown, a second ring groove 26 is provided behind the first ring groove 25 in the front side wall cavity of the assembly plate frame 2. The two have the same specification dimensions and structural shapes. The second ring groove 26 is concentric with the driving member 20. Since the positioning pin 23 is arranged in a nail - like structure, after installation, the tail part of the nail is movably inserted into the cavity wall of the wide part of the driving member 20, and the head part of the nail movably penetrates through the cavity wall and extends outward. The head part of the positioning pin 23 is arranged in a hemispherical structure. Also, since a positioning spring 24 is installed at the sliding connection of the positioning pin 23 and the driving member 20, and the positioning spring 24 is placed in the cavity wall of the wide part of the driving member 20 after installation, one end of it presses against the cavity wall, and the other end presses against the tail part of the positioning pin 23. Furthermore, since the distance dimension between the first ring groove 25 and the second ring groove 26 is equal to the maximum distance dimension of the sliding of the driving member 20, manually screwing the driving member 20 to drive the first linkage 11 and the second linkage 12 to slide, then pressing the driving member 20, so that the driving member 20 slides at the square rod end of the transmission rod 19. When the driving member 20 slides, the hemispherical end of the positioning pin 23 loses engagement with the first ring groove 25, causing the positioning pin 23 to contract and slide on the wide part of the driving member 20, and causing the positioning spring 24 to be elastically deformed under extrusion. After the driving member 20 slides, through the elastic deformation reset of the positioning spring 24, the positioning pin 23 extends and slides on the wide part of the driving member 20, and the hemispherical end of the positioning pin 23 engages with the second ring groove 26 to connect, positioning the driving member 20 after sliding;

[0075] Since the spline column 28 is fixed in the cavity of the front side wall groove of the assembly plate frame 2, a spline groove 27 concentric with it is provided in the wide part of the driving member 20. The spline groove 27 and the spline column 28 are on the same central axis and are correspondingly arranged. Also, since the number of tooth blocks of the spline column 28 is equal to the number of tooth blocks of the second gear part 21, and the thickness dimension of the spline column 28 is smaller than the maximum distance dimension of the sliding of the driving member 20. After the driving member 20 slides, the spline column 28 and the spline groove 27 are connected in a clamping manner, so that the spline column 28 limits and locks the driving member 20. Through the meshing action between the second gear part 21 and the second rack part 22, and through the clamping action between the transmission rod 19 and the driving member 20, the first linkage frame 11 and the second linkage frame 12 after sliding are indirectly locked.
