Description

Technical Field

[0001] The invention belongs to the technical field of assembled buildings, and in particular relates to an assembled plate with an external connection structure. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc., and are representatives of modern industrialized production methods because they use standardized design, factory production, assembly construction, information management, and intelligent applications.

[0003] Among them, plate construction is a common application type in prefabricated buildings. It is mainly assembled from prefabricated large internal and external wall panels, floor panels and roof panels, and is also called large-plate construction. Plate construction can reduce structural weight, improve labor productivity, and expand the use area and earthquake resistance of buildings. The inner wall panels of plate construction are mostly solid or hollow panels of reinforced concrete; the outer wall panels are mostly reinforced concrete composite panels with insulation layers, and can also be made of lightweight aggregate concrete, foam concrete or macroporous concrete. Wall panels with exterior finishes can also be made. The equipment in the building often uses centralized indoor pipe fittings or cassette toilets to improve the degree of assembly. The key issue of plate construction is node design. The integrity of the component connection should be guaranteed in the structure (the connection methods between the plates are mainly welding, bolt connection and post-cast concrete integral connection). In terms of waterproof structure, it is necessary to properly solve the waterproofing of the joints of the outer wall panels, as well as the thermal treatment of the floor seams and corners. The main disadvantage of large-panel buildings is that they have great restrictions on the shape and layout of the building; the internal divisions of large-panel buildings with small bays and horizontal load-bearing structures lack flexibility (the interiors of longitudinal walls, internal columns and large-span floor slabs can be flexibly divided).

[0004] In existing board buildings, screw connection is more common, but because the screw connection parts are all set inside the board, when it forms a complete building structure, it is impossible to directly detect whether the connection is stable from the outside. According to the existing construction industry acceptance standards, this connection method cannot pass the acceptance smoothly. At the same time, if special inspection or survey instruments are required to check the connection during maintenance, it is impossible to find possible hidden dangers in time. Summary of the invention

[0005] In order to solve the problems existing in the prior art, the present invention provides a wall panel structure. Different from the existing built-in connectors, the external connectors can not only achieve a better connection and fixing effect, but also directly check from the outside whether the connection structure is stable, and can successfully pass the acceptance, providing convenience for subsequent maintenance work.

[0006] The technical solution adopted by the present invention is:

[0007] In a first aspect, an assembled plate with an external connection structure is disclosed, which is connected and fixed to form a wall, and a plurality of spaces are separated by the wall, or the wall is enclosed inside to form an independent area; including:

[0008] The plate body is preformed by a mold and has a connecting groove on its outside;

[0009] A connecting piece, used to connect and fix at least two plates;

[0010] Wherein, the connecting member includes a rod member arranged in the connecting groove and a locking member. When the rod member is arranged in the connecting groove and one end is fixed, the plate body is tightened and fixed by arranging the locking member on the other side of the plate body.

[0011] First, the plate body is a prefabricated part, and the connection grooves on the outside are empty grooves formed by blocking the pouring of the placeholders in the mold. Generally, multiple groups of connection grooves are symmetrically arranged on the two large-area surfaces of the plate body, and clamped and tightened from both sides to form a better connection stability.

[0012] However, it should be noted that the claims do not limit the number and location, and the rod is only set on one side of the plate. As long as the specific structure and connection method are optimized, the fixing effect can also be achieved. Therefore, the scheme of setting the rod on one side or both sides belongs to the protection scope of the present invention.

[0013] The panels are connected to form a wall, and the panels at the ends of the wall are connected to other panels or fixed structures through connectors. If connected to other panels, a corner is formed, and an independent room is formed. The so-called fixed structure is generally a cast-shaped main structure of a building. First, its rods are inserted into the fixed structure, and then the panels are arranged along the rods in turn, and the panels are pressed against the fixed structure through locking members. Then the panels are fixed in turn, and each panel or multiple panels are connected and fixed with locking members.

[0014] The so-called locking member is sleeved on the rod, and the plate is pushed to one side by external force, and remains stable under the continuous action of external force. At this time, the locking member is operated to make it lean against one side of the plate and form a fixed relationship with the rod. Then the external force is removed, and the plate is locked and fixed.

[0015] It is also worth noting that the so-called rod refers to a member whose longitudinal (length direction) dimension is much larger than the transverse (perpendicular to the length direction) dimension. It should be considered that all components whose length direction is larger than the perpendicular to the length direction fall within this range. Since the plates are fixed to each other by tightening and fixing them with rods and locking members, soft steel cables can also be used to fix the structure.

[0016] In combination with the first aspect, the present invention provides a first implementation manner of the first aspect, wherein the plate body is provided with a plurality of groups of corresponding connection grooves on both sides;

[0017] The locking member is simultaneously fixed on two rods which are arranged on different surfaces and are on the same horizontal plane.

[0018] It is worth noting that the plate has a certain thickness, and its two sides are two opposite large-area surfaces, and the so-called multiple groups of correspondence refer to that more than two parallel connection grooves are provided on each surface, and the connection grooves are arranged along its width direction and have the same size. The connection grooves on both sides are arranged in a corresponding manner, which means that they have the same number and the same setting height, which is the horizontal height when the plate stands on the ground; at the same time, a staggered arrangement can also be adopted, and the connection grooves on each side surface have the same interval, and the corresponding connection grooves on both sides have a height difference.

[0019] In combination with the first embodiment of the first aspect, the present invention provides a second implementation of the first aspect, wherein the panels are connected to each other to form walls, and multiple groups of walls are combined to form a building;

[0020] The number of connecting grooves on the outer side of the plate body is greater than the number of connecting grooves on the inner side.

[0021] It is worth noting that if the panels are enclosed to form a building, appropriate bridges are provided at the connection between each wall, so that the external and internal rods are connected separately to form an annular fixing member. The external rods are used as the main load-bearing structure, which can save materials.

[0022] In combination with the first real-time mode of the first aspect, the present invention provides a third implementation manner of the first aspect, wherein a locking screw is provided on the locking member;

[0023] The locking screw is inserted into the locking member in a direction perpendicular to the axis of the rod and the end thereof abuts against the surface of the rod for position limiting and fixing.

[0024] It is worth mentioning that the locking member is provided with a screw hole, and the axis of the screw hole is perpendicular to the axis of the rod passing through the locking member. Since the rod passes through the plate body from the outside, multiple plate bodies are connected and limited, and multiple locking members are provided on the same side of each plate body for fixing, so that the plates in the same row are fixed against each other. The locking member and the rod are detachably limited, and specifically, the limit is achieved by fixing the locking screw. The principle is that a large downward pressure is formed by reciprocating in the direction perpendicular to the axis of the rod and contacting the surface of the rod at its end, resulting in a large static friction between the end of the locking screw and the surface of the rod.

[0025] The end of the locking screw is provided with an arc-shaped groove, which can conform to the surface of the rod, thereby increasing its contact area to form a sufficient downward pressure contact surface, thereby avoiding excessive concentration of friction and causing damage to the end face material of the rod or locking screw, affecting the limiting effect.

[0026] In combination with the first embodiment of the first aspect, the present invention provides a fourth implementation of the first aspect, wherein the rod is a screw structure, and the end of the locking screw is conformably engaged with the thread on the surface of the screw.

[0027] The static friction between the rod and the locking screw is mainly related to the pressure and the surface roughness. The pressure is related to the set thread density, while the surface roughness is determined by setting a special contact surface shape. The rod is a long screw structure with equidistant threads on its surface. The toothed pattern on the end face of the locking screw can conform to the thread and form a certain degree of bite, which can amplify the static friction and bring a better limiting effect.

[0028] In combination with the first embodiment of the first aspect, the present invention provides a fifth implementation of the first aspect, wherein a through slot is provided on the locking member, and the opening of the through slot is aligned with the rod member so that the locking member is sleeved on the rod member in a direction perpendicular to the axis of the rod member.

[0029] It is worth noting that in the actual installation process, since the rod has a certain length, a single rod may be connected to at least multiple plates. If the through hole of the locking member is not opened on the side when installing the plate, it is necessary to calculate the number of locking members required before installation, and insert them from the end of the rod in turn and move them to the corresponding side of the plate for positioning. The through-slot structure can directly insert the locking member on the rod from the side after the plate is pre-positioned, and then fix it with a locking screw.

[0030] In combination with the third embodiment of the first aspect, the present invention provides a sixth implementation of the first aspect, wherein a recessed groove is provided on the side surface corresponding to the thickness of the plate body, and the locking piece is inserted into the recessed groove when fixing the corresponding plate body.

[0031] In combination with the third embodiment of the first aspect, the present invention provides a seventh implementation manner of the first aspect, wherein the connecting member further comprises a fastener, the fastener has a clamping structure, the fastener is sleeved on the rod and is fixedly connected to the rod through the clamping structure;

[0032] The fastener also has a push rod, and when the fastener is fixed, the locking piece on the same side can be pressed against the surface of the plate body by operating the push rod.

[0033] In combination with the seventh embodiment of the first aspect, the present invention provides an eighth implementation manner of the first aspect, wherein the fastener is provided with a through hole for the rod to pass through, and an inner wall on one side of the through hole is provided with a channel extending outward in a direction perpendicular to the axis of the through hole, and the rod can enter the through hole laterally from the channel.

[0034] In combination with the first embodiment of the first aspect, the present invention provides a ninth implementation of the first aspect, wherein the locking member has a locking structure, and the locking structure contacts and presses the surface of the rod to form a fixing effect;

[0035] The operating end of the locking structure is arranged on a side surface of the rod passing through the locking member.

[0036] The beneficial effects of the present invention are:

[0037] (1) The present invention connects multiple panels to form a wall through external rods, and quickly positions them through locking members, so that the originally built-in connectors can be directly visible from the outside, especially the connection parts, and the connection status can be directly obtained from the outside, which can meet the acceptance and subsequent maintenance requirements;

[0038] (2) The present invention provides a fastener that cooperates with the locking member to quickly pre-position the locking member. Compared with the existing connection structure, it can be quickly assembled. Compared with the direct connection method of screwing the bolt, the method of forming a fixing effect by lateral extrusion of the locking bolt is more convenient. Furthermore, the toothed structure design at the end can maximize the limiting effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] Embodiment 1:

[0062] This embodiment discloses a plate structure, which is mainly used in prefabricated buildings. By connecting multiple plates 2 in parallel to form partitions, the internal space can be partitioned and separated by rapid assembly within the existing main structure of the building.

[0063] Specifically, if Figure 1 and Figure 2 As shown, it mainly includes two parts, with four plates 2 connected to each other in the middle and fixed columns 1 at both ends for fixing. The fixed columns 1 are the original cast-shaped building body, and the plate 2 is set between two fixed columns 1 to form a partition.

[0064] It is worth noting that the figure is for demonstration purposes only. In actual construction, the spacing between the fixed columns 1 is much larger than the width of four standard plates 2.

[0065] Different from the prior art, five rods 5 are provided on the inner and outer surfaces of the four plates, and a connecting groove 3 is provided on the surface of each plate. After the plates are connected, the connecting grooves 3 on the surfaces are aligned and connected. During assembly, one end of the rod 5 is first fixed to a connecting column on one side by an expansion bolt, and in the figure, it is directly fixed to the left fixing column 1. For each plate body 2, five locking members 4 are provided on the right side of the plate body 2 for tightening and fixing.

[0066] Since the fixing column 1 at the left end is a fixed structure, after the rod 5 is fixed, the adjacent plate 2 is directly pushed toward the fixing column 1 by applying external force from the right side with engineering tools, and when the left end face of the plate 2 is completely against the surface of the fixing column 1, five locking members 4 are set on the right end face for positioning. The locking member 4 is pressed against the right side of the plate 2 by operation, and the locking structure inside the locking member 4 presses the surface of the rod 5, so that a limiting relationship is formed between the locking member 4 and the rod 5. At this time, the external force is removed and the next plate 2 is installed.

[0067] Figure 3 It can be seen that the two end faces of the plate body 2 where the thickness is located are provided with mating convex and concave structures 2.1. On the same plate body 2, the left side is a convex strip structure and the right side is a groove structure. When the adjacent plate bodies 2 are pressed against and tightened by the rod 5 and the locking member 4, the combination of the convex strip and the groove can prevent the lateral external force from causing it to crack.

[0068] and Figure 3 A square groove 6 is provided on the surface of the plate body 2 in the vertical direction, and the square groove 6 is used to receive pipelines so as to form an internal wiring arrangement of the building.

[0069] It is worth noting that the plate body 2 in this embodiment is pre-cast and formed by a mold, and then transported to the installation site for assembly according to demand. Its surface notch structure is formed by a mold, and is covered by coating cement mortar or decorative panels after assembly.

[0070] Embodiment 2:

[0071] This embodiment is optimized and limited based on the above embodiment 1. Figure 3 and Figure 4As shown, since the corresponding connecting groove 3 structures are provided inside and outside the single plate body 2, and the connecting grooves 3 are correspondingly arranged on the same horizontal plane, a total of two rods 5 pass through the single locking member 4.

[0072] In this embodiment, in order to install the locking member 4, a fastener 8 structure is provided on the rod 5, which can be fixed on the rod 5, and the fastener 8 has a push rod 10 for pushing the locking member 4 to fit the plate 2. The plate 2 is provided with a side of the fastener 8, and a corresponding sinking groove 2.2 structure is provided. The sinking groove 2.2 structure is through-set in the length direction (that is, the thickness direction of the plate 2), and the cross-section of the sinking groove 2.2 is a rectangular structure, corresponding to the locking member 4. As can be seen in the figure, the locking member 4 is provided with two through holes for the rod 5 to pass through.

[0073] In order to lock and fix the locking member 4 and the rod 5, fastening screw holes 15 are provided on both sides of the locking member 4, and the fastening screw holes 15 are connected to the through hole where the rod 5 is located. A locking bolt is arranged in the fastening screw hole 15, and the locking bolt is screwed to make its end abut against the surface of the rod 5 to achieve a fixing effect.

[0074] It is worth noting that the locking bolt is only shown in the figure as being inserted into the fastening screw hole 15. The locking bolt in this embodiment includes two parts, one end of which is provided with a stopper 13. The stopper 13 is made of plastic and is rotatably connected to the main structure of the locking bolt. The stopper 13 can move linearly in the fastening screw hole 15 as the locking bolt is turned, and its end is designed with an arc surface, which can have a large contact area when it is against the surface of the rod 5.

[0075] The arc surface 16.1 of the stopper 13 is provided with concave and convex patterns, and the locking bolts are pressed to deform the surface of the contact rod 5, thereby obtaining a larger static friction force to limit the movement of the locking member 4. During installation, the locking member 4 needs to be moved into the sink 2.2 first, and then the locking member 4 needs to be pushed into the sink 2.2 by external engineering equipment, or the rod 5 needs to be continuously pulled outward. Then, the external force is maintained, and the locking bolts are inserted from both sides to lock, and finally the external force is removed to reach a stable state.

[0076] Since decorative panels and insulation layers will be set on the outside of the wall, the connecting grooves 3 will be sealed by filling with cement mortar or other plaster after the rods 5 are fixed, or the outside will be directly blocked by panels, and openings will be set at key connections for inspection during later maintenance.

[0077] In this embodiment, the plate bodies 2 are directly connected to the side surfaces of the plate bodies 2. In order to prevent the locking member 4 from affecting the connection stability, the depth of the recess 2.2 is slightly greater than the width of the locking member 4, and the locking member 4 can be completely sunk into the recess 2.2 when fixed.

[0078] Embodiment 3:

[0079] This embodiment is optimized and limited based on the above embodiment 1. Figure 5-9 As shown, a locking member 4 structure is shown, which is different from the above-mentioned embodiment 2 in that the insertion direction of the locking screw 7 and the fixing method of the locking screw 7 are adjusted to improve stability.

[0080] In the above-mentioned embodiment 2, the locking member 4 has a simple structure and is easy to operate. For the sake of convenience, the locking screws 7 are arranged to be inserted from both sides in the length direction. However, since the width of the entire locking member 4 is not greater than the width of the plate body 2, and the depth of the connecting groove 3 must be less than half of the thickness of the plate body 2, the distance between the two rods 5 passing through the locking member 4 cannot be reduced. As can be seen in the figure, the travel of the locking screws 7 is relatively short.

[0081] In this embodiment, the multiple plates 2 are also fixedly connected by five rods 5 inside and outside, and a recess 2.2 is provided on the right side of the plate 2 for fixing the locking member 4. The locking member 4 is not only provided with a through hole and a screw hole, but also provided with an enlarged cavity at the end of the screw hole, and a pressing block 12 is provided in the enlarged cavity. The pressing block 12 can slide in the enlarged cavity, and the sliding direction is perpendicular to the axis of the rod 5, and the rod 5 is laterally pressed and fixed by the pressing block 12. The moving direction of the locking bolt is perpendicular to the moving direction of the pressing block 12, and the transmission is realized by the cooperation of the abutment block 13 provided at the end of the locking bolt and the pressing block 12.

[0082] Specifically, the block 13 structure can also slide in the expansion cavity, but unlike the above-mentioned embodiment 2, the block 13 is confined in the expansion cavity and is not connected to the locking screw 7 as an independent structure. Instead, the contact surface with the locking screw 7 is concave to form a concave spherical surface, which is pushed by the convex spherical surface at the end of the locking screw 7. Considering that the locking member 4 is disassembled and assembled less frequently, and generally maintains the initial state for a long time after being fixed, no reset spring structure is set in the expansion cavity.

[0083] In order to achieve transmission between the stopper 13 and the pressing block 12, the contact surfaces of the stopper 13 and the pressing block 12 are both set as inclined structures. When the stopper 13 is pushed by the locking screw 7, the stopper 13 can transmit the vertical thrust to the pressing block 12 through the inclined force component. Since the pushing direction of the locking screw 7 is along the axial direction of the rod 5, it is not limited by the length of the locking member 4. By setting a longer and denser thread, it can prevent the stopper 13 from moving during fixing and affecting the fixing effect.

[0084] This embodiment also discloses a fastener 8 that cooperates with the locking member 4 to achieve a fixing operation. Figure 6As shown in the partial enlarged view in FIG. 1 , the fastener 8 is also assembled on the rod 5. When viewed from the top, the top view of the fastener 8 is a door-shaped structure. The fastener 8 is also provided with a fastening through hole 18 for the rod 5 to pass through, and a channel connected to the fastening through hole 18 is also provided at the bottom. The channel is actually the opening of the fastening through hole 18 at the bottom, so that the rod 5 can be directly inserted into the fastening through hole 18 from the bottom, avoiding the need to insert the fastener 8 from the end of the rod 5 when installing, thereby improving assembly efficiency.

[0085] The fastener 8 also has a compression structure similar to the locking bolt, that is, the fastening screw 9 shown in the figure. The fastening screw 9 is also a screw structure, but since its overall width does not need to be considered, it can be inserted from both sides, and protruding extension parts are provided at corresponding positions on both sides to increase the stroke of the screw.

[0086] The fastener 8 is also provided with a push rod 10, which is threadedly matched with the fastener 8. The end of the push rod 10 is aligned with the surface of the adjacent locking member 4. After the push rod 10 is turned, it can press against the locking member 4 to squeeze it into the sink 2.2 to achieve compression.

[0087] Specific principle: first, set the locking member 4 in the sink 2.2, then move the fastener 8 to the corresponding position, and operate the clamping structure on both sides to fix the fastener 8 on the rod 5. Then turn the push rod 10 to fix the locking member 4 in the sink 2.2 through the push rod 10, then operate the locking bolt to fix the limit position, and finally remove the fastener 8 to start installing another locking member 4.

[0088] Embodiment 4:

[0089] like Figure 10-12 As shown, this embodiment also discloses a plate body 2 and a connecting member for connecting the plate bodies 2 to form a wall.

[0090] Specifically, it includes multiple panels 2 that are horizontally bonded and spliced. The figure shows the specific structure of a single panel 2, which is prefabricated and cast by a mold. It can be seen that the panel 2 is a rectangular panel that is longer in the vertical direction, and is provided with staggered rectangular grooves inside and outside in the vertical height direction. The rectangular grooves are used to arrange the lines, so that the wires will be hidden in the panel 2 after the entire wall is formed.

[0091] The plate body 2 is also provided with five equally spaced and parallel connection grooves 3 on both inner and outer sides in the horizontal direction. The depth of the connection groove 3 is greater than that of the rectangular groove, and the inner bottom is an arc-shaped bottom surface. When the plate bodies 2 are arranged in close contact with each other, each connection groove 3 is interconnected to form a through groove structure, and the same rod 5 is provided in the connection grooves 3 of multiple plate bodies 2 for connection.

[0092] As can be seen in the figure, for demonstration purposes, two rods 5 are provided in the bottommost connecting groove 3, and a sink groove 2.2 is provided on the right side of the plate body 2, and a locking member 4 is provided in the sink groove 2.2. The two rods 5 symmetrically pass through the locking member 4, which is fixed and tightened by the locking member 4.

[0093] exist Fig.12 As can be seen in the figure, the locking member 4 has two locking through holes 11 for the rod 5 to pass through. The lower part of the locking through hole 11 is hollowed out to form an opening, and the width of the opening is greater than or equal to the cross-sectional diameter of the locking through hole 11. Since the original structural design of the locking through hole 11 requires the locking member 4 to be inserted from the end of the rod 5 for fixing during installation, the opening is provided so that the rod 5 can vertically enter the locking through hole 11 from the bottom, which is convenient for installation. The sink groove 2.2 on the side of the plate body 2 can also limit the locking member 4 to prevent it from sliding out from the top and losing connection with the rod 5.

[0094] Two dovetail grooves in the same direction as the axis of the through hole are provided on the inner wall of the opening, and an insert block 16 is connected through the dovetail grooves. The insert block 16 can be inserted along the axis of the locking through hole 11, and the insert block 16 is provided with two insert strips corresponding to the dovetail grooves, and a through fixing hole is provided in the insert strip, and the insert block 16 is fixed to the locking member 4 by inserting bolts.

[0095] It can be seen that an arc surface 16.1 is provided above the plug block 16, which blocks and encloses the opening of the locking through hole 11 of the locking member 4 to form a complete through hole structure. A gradually enlarged protrusion structure is provided at the outer end of the arc surface 16.1. The protrusion structure is made of a deformable rubber material and gradually protrudes outward from the midline position of the plug block 16. In other words, when the rod 5 is set in the locking through hole 11, the plug block 16 is inserted into the locking member 4, and when the protrusion structure presses against the rod 5, it will be deformed and press against the rod 5. If the deformation amplitude of the protrusion structure exceeds 50% after the plug block 16 is fully inserted and fixed, the rod 5 will be subjected to a large lateral extrusion force. A suitable concave-convex surface structure can be provided so that the locking member 4 has a better limiting effect to prevent it from being frustrated during use.

[0096] This embodiment also includes a special fixing tool: a fastener 8. The fastener 8 includes two parts that are interlocked: an upper fastener and a lower fastener. The upper fastener is a main structure, and a fastening screw hole 15 is provided at its end. The fastening screw hole 15 is used to cooperate with the push rod 10 structure, so that the push rod 10 can rotate to push the locking block against the plate body 2.

[0097] Different from the above-mentioned embodiment 3, the fastener 8 in this embodiment directly forms a clamping and fixing state with the rod body surface after being fastened, and the upper fastener and the lower fastener are fastened by bolts, which is also for the convenience of fixing on the rod 5 from the side, without having to penetrate from the end of the rod 5. Among them, the upper fastener and the lower fastener are provided with a tightening hole 14, which is convenient for the bolt to penetrate for fixing.

[0098] The specific operating principles and steps are the same as those of the above-mentioned embodiment 3 and will not be described in detail here.

[0099] Embodiment 5:

[0100] This embodiment optimizes the locking member 4 based on the above embodiment 1, wherein Fig.13 and 14 As shown, the rod 5 is provided with multiple thread segments, the spacing of the thread segments is related to the width of the plate 2, and generally the center distance of the thread segments is equal to the width of the plate 2. During assembly, by fixing the end of the rod 5 to a certain depth on the fixing column 1, the rod 5 has a thread segment at each position where the locking member 4 is used to fix the plate 2. At this time, the locking member 4 is fixed in the sink groove of the plate 2 by setting a locking bolt 19, thereby improving the assembly efficiency, and the structure is simple and the cost is low.

[0101] It is worth noting that, what is not shown in the figure is that an opening is also provided on one side of the locking through hole 11 of the locking member 4, and the length of the opening is the same as the length of the locking through hole 11, so that the rod 5 can directly enter the locking through hole 11 from the side.

[0102] The present invention is not limited to the above optional implementations, and anyone can derive other various forms of products under the enlightenment of the present invention. The above specific implementations should not be understood as limiting the scope of protection of the present invention. The scope of protection of the present invention should be based on the definition in the claims, and the description can be used to interpret the claims.
