Description

Technical Field

[0001] The present application relates to the technical field of building formwork support, and in particular to a connection assembly and a support frame. Background Art

[0002] During the construction process, a support frame is generally set up for supporting the building formwork. With the continuous improvement of the technical level of the construction industry, the component structure of the support frame is continuously improved and optimized, so that the spacing between the vertical poles of the support frame is further increased. The increase in the spacing between the vertical poles not only reduces the material consumption and reduces the cost, but also meets the requirements of construction.

[0003] However, the increase in the spacing between the vertical poles results in the existing support frame's horizontal bar being insufficient in length, and the horizontal bar cannot connect two adjacent vertical poles. Adding a horizontal bar of a new specification requires a large investment, and the existing horizontal bar cannot continue to be used, resulting in waste. Summary of the invention

[0004] In view of this, the present application provides a connection assembly and a support frame, which can make full use of cross bars of existing specifications, improve the utilization rate of the cross bars, and meet the support strength requirements of the building design.

[0005] On the one hand, an embodiment of the present application provides a connecting component for connecting two rod-like structures, the connecting component including a connecting member, a limiting member and two first fixing members, the limiting member being fixedly connected to the connecting member; the two ends of the connecting member are respectively fixedly connected to the two rod-like structures one by one through the two first fixing members, the limiting members are respectively connected to the two first fixing members and are spaced apart from the connecting member.

[0006] The above-mentioned connecting component can be applied to the cross bar of the support frame, and the above-mentioned rod-like structure can be a cross bar of the original specification of the support frame. The two rod-like structures are connected together by a connecting piece, a limit piece and two first fixing components, and the two ends of the connecting piece are respectively connected to a rod-like structure by a first fixing component, and the limit piece is respectively connected to the connecting piece and the first fixing component, so that the connecting piece, the limit piece and the first fixing component are relatively fixed, and the connecting piece, the limit piece and the first fixing component can share the pressure together, and improve the structural stability between the connecting piece and the limit piece, so that the two rod-like structures connected by the above-mentioned connecting component can meet the requirements of the building design on the support strength, thereby making full use of the cross bars of existing specifications, improving the utilization rate of the cross bars and reducing costs.

[0007] In at least one embodiment, the first fixing component includes a connecting head, which is used to be fixedly connected to the rod-like structure, and the connecting head has a connecting groove; the two ends of the connecting piece are respectively arranged in the connecting grooves of the connecting heads of the two first fixing components, and the two ends of the connecting piece are respectively connected to the connecting heads of the two first fixing components.

[0008] The connecting grooves of the two first fixing components limit the two sides of the connecting piece in the thickness direction, thereby improving the connection stability between the connecting head of the first fixing component and the connecting piece. Since the connecting head is fixedly connected to the rod-like structure, the connection stability between the rod-like structure and the connecting piece is further improved.

[0009] In at least one embodiment, the connecting member includes a first connecting plate and a stop protrusion, and both ends of the first connecting plate are respectively located in the connecting grooves of the two first fixing components; the stop protrusion is connected to the first connecting plate, and the stop protrusion respectively abuts against the connecting heads of the two first fixing components.

[0010] By setting the stop protrusion, the displacement of the connector in the length direction of the first connecting plate can be limited, thereby improving the reliability of the connection between the connector and the connecting piece.

[0011] In at least one embodiment, the stopping protrusion is an annular protrusion.

[0012] By configuring the stop protrusion as an annular protrusion, the overall volume of the annular protrusion is larger, thereby improving the structural strength of the stop protrusion.

[0013] In at least one embodiment, the stop protrusion has a first contact surface that contacts the connecting head, and the first contact surface is a curved surface that protrudes toward the connecting head.

[0014] By configuring the first contact surface as a curved surface protruding toward the connecting head, the stop protrusion can have an abutting force toward the connecting head, thereby improving the connection effect and connection stability between the connecting member and the connecting head.

[0015] In at least one embodiment, the connecting head includes two connecting blocks arranged opposite to each other, and a connecting groove is formed between the two connecting blocks; two stop protrusions are provided, and the two stop protrusions are respectively arranged on both sides of the thickness direction of the first connecting plate, and the stop protrusions respectively abut against a connecting block of the connecting head of the two first fixing components.

[0016] By cooperating between the two stop protrusions and the connecting heads of the two first fixing components, the contact area between the connecting piece and the connecting head is increased, so that the force distribution on both sides of the thickness direction of the first connecting plate is uniform, thereby further improving the connection effect and connection stability between the connecting piece and the connecting head.

[0018] By changing the width of the second connecting plate section, there is sufficient contact area between the first connecting plate and the inner wall of the connecting head close to the connecting groove. In addition, since the width of the first connecting plate section of the first connecting plate is smaller and the partial width of the second connecting plate section is smaller, the material of the first connecting plate is reduced, making the weight of the first connecting plate lighter.

[0019] In at least one embodiment, the first fixing component includes a pin piece, the pin piece is passed through the connecting head and the connecting member, and the limiting member is covered on the pin piece.

[0020] By setting the pin piece, a fixed connection between the connecting head and the connecting piece is achieved, and the connecting head and the connecting piece connected by the pin piece are detachable to facilitate the replacement of the worn connecting piece. Moreover, the limit member cover is arranged on the pin piece, which can improve the problem of easy shaking of the pin piece and enhance the structural stability of the pin piece.

[0021] In at least one embodiment, the limiting member includes: a second connecting plate and two first limiting plates, the two first limiting plates are respectively connected to the second connecting plate and are located on both sides of the width direction of the second connecting plate, the two first limiting plates and the second connecting plate form a limiting groove, the pin plates of the two first fixing components are both located in the limiting groove, and the two first limiting plates are located on both sides of the pin plate in the thickness direction.

[0022] By limiting the position of the limit groove, the position of both sides of the pin piece in the thickness direction can be limited to improve the problem that the pin piece is easy to shake on both sides along the thickness direction of the pin piece, thereby improving the structural stability of the first fixed component; and, by setting the limit groove of the limit member to a structure surrounded by multiple connecting plates, the plate-like structure is relatively flat, which can make the limit member occupy a smaller volume and use less material.

[0023] In at least one embodiment, the connecting assembly also includes a second fixing assembly, which is located between the two first fixing assemblies. The second fixing assembly includes a first bolt and a first nut, the first bolt passes through the connecting member and the limiting member, the first bolt is against the connecting member, and the first nut is threadedly connected to the first bolt and is against the limiting member.

[0024] By setting the first bolt and the first nut, a fixed connection between the connecting member and the limiting member is achieved. At the same time, the connection between the connecting member and the limiting member through the first bolt and the first nut is detachable to facilitate the disassembly and assembly of the connecting member and the limiting member, thereby facilitating the replacement of severely worn connecting members and / or limiting members.

[0025] On the other hand, an embodiment of the present application provides a support frame, including multiple cross bar assemblies and multiple vertical poles, at least some of the cross bar assemblies include a connecting assembly and two rod-like structures, the connecting assembly is the above-mentioned connecting assembly, and the two rod-like structures are connected by the connecting assembly; two adjacent vertical poles are connected by a cross bar assembly.

[0036] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0037] In the related art, the support frame includes a plurality of vertical poles and a plurality of horizontal poles. With the continuous improvement of the support frame, the distance between two adjacent vertical poles increases, resulting in the fact that the length of the horizontal poles of the existing specifications is not enough to connect the two adjacent vertical poles, thus causing the following problems: (1) Increasing the length of the horizontal poles of the new specifications requires a large investment, and it will also cause the existing horizontal poles to be unable to continue to be used, resulting in waste; (2) If a single connecting piece is directly used to connect the two horizontal poles, it is difficult to meet the support strength requirements of the architectural design of the support frame, resulting in insufficient stability of the support frame.

[0038] One embodiment of the present application provides a connection assembly, which is used to connect two rod-shaped structures. The connection assembly includes a connection member, a stopper and two first fixing members, and the stopper is fixedly connected to the connection member; the two ends of the connection member are fixedly connected to the two rod-shaped structures one by one through the two first fixing members, and the stopper is connected to the two first fixing members and is arranged at intervals with the connection member. The connection assembly can be applied to the crossbar of the support frame, and the rod-shaped structure can be a crossbar of the original specification of the support frame. The two rod-shaped structures are connected together through the connection member, the stopper and the two first fixing members, and the two ends of the connection member are connected to a rod-shaped structure through a first fixing member, and the stopper is connected to the connection member and the first fixing member, so that the connection member, the stopper and the first fixing member are relatively fixed, and the connection member, the stopper and the first fixing member can share the pressure received, and improve the structural stability between the connection member and the stopper, so that the two rod-shaped structures connected by the connection assembly can meet the requirements of the architectural design on the support strength, thereby making full use of the crossbar of the existing specifications, improving the utilization rate of the crossbar, and reducing the cost.

[0039] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features in the following embodiments and examples can be combined with each other.

[0040] See also Figure 1 An embodiment of the present application provides a support frame, which includes a plurality of cross bar assemblies 2 and a plurality of vertical poles 3. Two adjacent vertical poles 3 are connected by a cross bar assembly 2. At least part of the cross bar assembly 2 includes a connecting assembly 1 and two rod-like structures 200. The two rod-like structures 200 are connected by the connecting assembly 1.

[0041] The rod-like structure 200 can be a crossbar of the original specifications of the support frame. Two rod-like structures 200 are connected by a connecting component 1 to form a crossbar component 2 of the support frame, thereby making full use of the crossbars of existing specifications, improving the utilization rate of the crossbars and reducing costs.

[0042] Specifically, in the relevant technology, existing specifications of cross bars include cross bars of 300mm, 600mm, 900mm and 1200mmm; among them, the "300mm, 600mm, 900mm, 1200mmm" in the above-mentioned cross bars refer to cross bars suitable for two adjacent vertical poles with a spacing of "300mm, 600mm, 900mm, 1200mm", rather than the net length of the cross bar. The spacing between two adjacent vertical poles refers to the distance between the central axes of the two adjacent vertical poles.

[0043] When the distance between two adjacent vertical poles is 1800 mm, two existing 900 mm cross bars can be used. The two 900 mm cross bars are connected by a connecting assembly 1 to form a cross bar assembly 2, and the two vertical poles are connected by the cross bar assembly 2.

[0044] See also Figure 2 In some embodiments, the connecting component 1 includes a connecting member 10, a limiting member 20 and two first fixing members 30, and the limiting member 20 is fixedly connected to the connecting member 10; the two ends of the connecting member 10 are respectively fixedly connected to the two rod-like structures 200 in a one-to-one correspondence through the two first fixing members 30, and the limiting member 20 is connected to both the first fixing members 30.

[0045] The two rod-like structures 200 are connected together by a connector 10, a limiter 20 and two first fixing components 30. Each end of the connector 10 is connected to a rod-like structure 200 through a first fixing component 30, and the limiter 20 is respectively connected to the connector 10 and the two first fixing components 30, so that the connector 10, the limiter 20 and the first fixing components 30 are relatively fixed. The connector 10, the limiter 20 and the first fixing components 30 can share the pressure together, and improve the structural stability between the connector 10 and the limiter 20, so that the two rod-like structures 200 connected by the above-mentioned connecting component 1 can meet the requirements of the building design on the support strength, thereby making full use of the existing specifications of the cross bars, improving the utilization rate of the cross bars and reducing costs.

[0046] In some embodiments, the connecting assembly 1 includes a connecting rod (not shown), both ends of which are fixedly connected to the connecting member 10 and the limiting member 20 respectively, and the connecting rod is located between the two first fixing assemblies 30; wherein the connecting rod is respectively welded to the connecting member 10 and the limiting member 20 to form an integral structure.

[0047] See also Figure 2 and Figure 3 In some embodiments, the connecting component 1 further includes a second fixing component 40 , and the second fixing component 40 is located between the two first fixing components 30 , and the connecting member 10 and the limiting member 20 are fixedly connected via the second fixing component 40 .

[0048] See also Figure 2 and Figure 3 In some embodiments, the second fixing assembly 40 includes a first bolt 41 and a first nut 42. The first bolt 41 passes through the connecting member 10 and the limiting member 20. The first bolt 41 is against the connecting member 10. The first nut 42 is threadedly connected to the first bolt 41 and is against the limiting member 20.

[0049] By setting the first bolt 41 and the first nut 42, the fixed connection between the connecting member 10 and the limiting member 20 is achieved. At the same time, the connection between the connecting member 10 and the limiting member 20 through the first bolt 41 and the first nut 42 is detachable to facilitate the disassembly and assembly of the connecting member 10 and the limiting member 20, thereby facilitating the replacement of the connecting member 10 and / or the limiting member 20 that are severely worn.

[0050] Specifically, the first bolt 41 itself has a nut, and the nut of the first bolt 41 is disposed against the connecting member 10 .

[0051] In some embodiments, the first fixing component 30 includes a connecting head 31, which is used to be fixedly connected to the rod-like structure 200, and the connecting head 31 has a connecting groove 310; the two ends of the connecting piece 10 are respectively arranged in the connecting grooves 310 of the connecting heads 31 of the two first fixing components 30, and the two ends of the connecting piece 10 are respectively connected to the connecting heads 31 of the two first fixing components 30, so as to limit the two sides of the connecting piece 10 in the thickness direction through the connecting grooves 310 of the two first fixing components 30, thereby improving the connection stability between the connecting head 31 of the first fixing component 30 and the connecting piece 10. Since the connecting head 31 is fixedly connected to the rod-like structure 200, the connection stability between the rod-like structure 200 and the connecting piece 10 is further improved.

[0052] In some embodiments, the connector 31 and the rod-shaped structure 200 form an integral structure. Specifically, the connector 31 and the rod-shaped structure 200 are welded into an integral structure.

[0053] See also Figure 3 and Figure 4 In some embodiments, the connecting member 10 includes a first connecting plate 11 and a stop protrusion 12, and both ends of the first connecting plate 11 are connected to the two rod-like structures 200 through a first fixing component 30; the stop protrusion 12 is connected to the first connecting plate 11, and the stop protrusion 12 respectively abuts against the connecting heads 31 of the two first fixing components 30.

[0054] By setting the stop protrusion 12 , the displacement of the connecting head 31 in the length direction of the first connecting plate 11 can be limited, thereby improving the stability of the connection between the connecting head 31 and the connecting member 10 .

[0055] In some embodiments, the stop protrusion 12 includes two protrusion segments, the two protrusion segments are arranged at an interval and opposite to each other, and the two protrusion segments abut against the connecting heads 31 of the two first fixing components 30 in a one-to-one correspondence.

[0056] In some embodiments, the stop protrusion 12 is an annular protrusion. By setting the stop protrusion 12 as an annular protrusion, compared with setting two protrusion segments separately, the overall volume of the annular protrusion is larger, thereby improving the structural strength of the stop protrusion 12.

[0057] See also Figure 3 and Figure 5 In some embodiments, the stop protrusion 12 has a first contact surface 120 that contacts the connector 31 , and the first contact surface 120 is a curved surface that protrudes toward the connector 31 .

[0058] If the first contact surface 120 of the stop protrusion 12 is set to a plane or a concave surface, there will be a large gap between the first contact surface 120 and the connecting head 31, which will affect the connection effect between the connecting piece 10 and the connecting head 31, making the connecting piece 10 easy to displace in the length direction of the first connecting plate 11. By setting the first contact surface 120 as a surface protruding toward the connecting head 31, the stop protrusion 12 can have an abutting force toward the connecting head 31, thereby improving the connection effect and connection stability between the connecting piece 10 and the connecting head 31.

[0059] In some embodiments, the first contact surface 120 is an arc-shaped surface.

[0060] In some embodiments, the stop protrusion 12 and the first connecting plate 11 are an integral structure. Thus, the stop protrusion 12 and the first connecting plate 11 are integrated into one body, and no additional parts are required to stop the connector 31 , thereby simplifying the structure of the connecting assembly 1 .

[0061] In one embodiment, the stop protrusion 12 and the first connecting plate 11 are welded into an integrated structure.

[0062] In another embodiment, the stop protrusion 12 and the first connecting plate 11 are formed into an integral structure by cutting, stamping or other processes.

[0063] See also Figure 3 and Figure 4 In some embodiments, each connecting head 31 includes two connecting blocks 311, and a connecting groove 310 is formed between the two connecting blocks 311; wherein: two stop protrusions 12 are provided, and the two stop protrusions 12 are respectively provided on both sides of the thickness direction of the first connecting plate 11, and the stop protrusions 12 respectively abut against a connecting block 311 of the connecting heads 31 of the two first fixing components 30.

[0064] Through the cooperation between the two stop protrusions 12 and the connecting heads 31 of the two first fixing components 30, the contact area between the connecting piece 10 and the connecting head 31 is increased, so that the force distribution on both sides of the thickness direction of the first connecting plate 11 is uniform, thereby further improving the connection effect and connection stability between the connecting piece 10 and the connecting head 31.

[0065] In some embodiments, both stop protrusions 12 are annular protrusions.

[0066] In some embodiments, the two stop protrusions 12 and the first connecting plate 11 are integrally formed.

[0067] In some embodiments, in each cross bar assembly 2, connecting heads 31 are provided at both ends of each rod-like structure 200, the connecting head 31 at one end of a rod-like structure 200 abuts against the vertical pole 3, and the connecting head 31 at the other end of a rod-like structure 200 abuts against the stop protrusion 12 of the connecting member 10. Such an arrangement allows both ends of each rod-like structure 200 to be restricted, thereby improving the structural stability between the cross bar assembly 2 and the two vertical poles 3.

[0068] See also Figure 5 and Figure 6 In some embodiments, the first connecting plate 11 includes a first connecting plate segment 111 and two second connecting plate segments 112, the first connecting plate segment 111 is connected to the limit member 20, and the stop protrusion 12 is set on the first connecting plate segment 111; the two second connecting plate segments 112 are connected to the two ends of the first connecting plate segment 111 one by one, and the two second connecting plate segments 112 are connected to the connecting grooves 310 of the two first fixing components 30 one by one; wherein, along the direction away from the stop protrusion 12, the width of the second connecting plate segment 112 gradually increases, and the width of the first connecting plate segment 111 is equal to the minimum width of the second connecting plate segment 112.

[0069] By changing the width of the second connecting plate segment 112, there is sufficient contact area between the first connecting plate 11 and the inner wall of the connecting head 31 on the side close to the connecting groove 310. In addition, since the width of the first connecting plate segment 111 of the first connecting plate 11 is smaller and the partial width of the second connecting plate segment 112 is smaller, the material of the first connecting plate 11 is reduced, making the weight of the first connecting plate 11 lighter.

[0070] Optionally, the first connecting plate 11 may be in other shapes such as a disc or a rectangular structure.

[0071] Specifically, the first connecting plate segment 111 is connected to the limiting member 20 via the second fixing assembly 40 .

[0072] In some embodiments, the first connecting plate segment 111 and the second connecting plate segment 112 are an integral structure.

[0073] In some embodiments, the first connecting plate segment 111 and the two second connecting plate segments 112 of the first connecting plate 11 are cut from a plate-like structure, so that the first connecting plate segment 111 and the second connecting plate segment 112 form an integral structure. The cut waste can be recycled.

[0074] See also Figure 3 and Figure 4In some embodiments, the limiting member 20 has a limiting groove 210, and parts of the two first fixing components 30 are located in the limiting groove 210, so that the structural stability of the first fixing components 30 is improved through the limiting effect of the limiting groove 210 of the limiting member 20, and because the two first fixing components 30 are fixedly connected to the rod-like structure 200, the structural stability of the first fixing components 30 is improved while also improving the connection stability between the two rod-like structures 200.

[0075] See also Figure 3 and Figure 4 In some embodiments, each first fixing assembly 30 includes a pin 32, the pin 32 is inserted through the connector 31 and the connector 10, and the stopper 20 is covered on the pin 32. By providing the pin 32, the connector 31 and the connector 10 are fixedly connected, and the connector 31 and the connector 10 connected by the pin 32 are detachable to facilitate the replacement of the worn connector 10. Moreover, the stopper 20 is covered on the pin 32, which can improve the problem of the pin 32 being easy to shake and improve the structural stability of the pin 32.

[0076] In some embodiments, the width direction of the pin piece 32 extends along the distribution direction of the two rod-like structures 200 .

[0077] Specifically, the length direction of the connecting rod (not shown) welded to the connecting member 10 and the limiting member 20 is the insertion direction of the pin piece 32 .

[0078] In some embodiments, the limiting member 20 includes a second connecting plate 21 and two first limiting plates 22. The two first limiting plates 22 are respectively connected to the second connecting plate 21 and are located on both sides of the width direction of the second connecting plate 21. The two first limiting plates 22 and the second connecting plate 21 form a limiting groove 210. The pin sheets 32 of the two first fixing components 30 are both located in the limiting groove 210. The two first limiting plates 22 are located on both sides of the pin sheet 32 ​​in the thickness direction.

[0079] By limiting the position of the limiting groove 210, the position of both sides of the pin piece 32 in the thickness direction can be limited to improve the problem that the pin piece 32 is easy to shake along both sides of the thickness direction of the pin piece 32, thereby improving the structural stability of the first fixing component 30; and, by setting the limiting groove 210 of the limiting member 20 to a structure surrounded by multiple connecting plates, the plate-like structure is relatively flat, which can make the limiting member 20 occupy a smaller volume and use less material.

[0080] Specifically, the two side walls of the pin piece 32 in the thickness direction are gap-matched with the first limiting plate 22 .

[0081] See also Figure 5 and Figure 7In some embodiments, the stop protrusion 12 is an annular protrusion, and the annular protrusion and the first connecting plate 11 form a receiving groove 121. The limit member 20 includes a third connecting plate 23 and two fourth connecting plates 24. The two fourth connecting plates 24 are respectively connected to the two ends of the third connecting plate 23. The two fourth connecting plates are bent with the third connecting plate 23. The third connecting plate 23 is located in the receiving groove 121, and the third connecting plate 23 is connected to the connecting member 10 through the first bolt 41 and the first nut 42 of the second fixing component 40. The two fourth connecting plates 24 are respectively connected to the pin plates 32 of the two first fixing components 30 to improve the structural stability of the pin plates 32.

[0082] See also Figure 7 In some embodiments, the third connecting plate 23 includes a first bent plate segment 231 and two second bent plate segments 232. The two second bent plate segments 232 are respectively connected to the two ends of the length direction of the first bent plate segment 231 and are arranged at an angle. A "U-shaped structure" is formed between the first bent plate segment 231 and the two second bent plate segments 232.

[0083] Specifically, the two fourth connecting plates 24 are pressed on the pin piece 32 .

[0084] Specifically, the stop protrusion 12 cooperates with the pin piece 32 to make the connection between the two rod-shaped structures 200 more stable.

[0085] In some embodiments, both of the two fourth connecting plates have a limiting groove 210 .

[0086] In some embodiments, the pin piece 32 is provided with two limiting protrusions 33 , which are arranged on both sides of the pin piece 32 in the thickness direction and located at one end of the pin piece 32 away from the limiting member 20 , and the two limiting protrusions 33 are limitedly matched with the connecting head 31 .

[0087] By setting the limiting protrusion 33, the displacement of the pin piece 32 along its length direction can be limited, thereby improving the reliability of the connection between the pin piece 32 and the connecting head 31; and the connecting head 31 and the pin piece 32 can be made not easily separated, reducing the chance of losing the pin piece 32.

[0088] In some embodiments, the connection assembly 1 includes a limiting fixture, which is disposed through the pin piece 32, and the two ends of the limiting fixture protrude from both sides of the thickness direction of the pin piece 32, so as to form limiting protrusions 33 on both sides of the thickness direction of the pin piece 32. The limiting protrusions 33 are formed by the limiting fixture, which facilitates the disassembly and assembly of the limiting protrusions 33, thereby facilitating the disassembly and assembly of the pin piece 32 and the connector 31.

[0089] In some embodiments, the limiting fixing member includes a second bolt and a second nut, the second nut is threadedly connected to one end of the second bolt, and the second bolt itself has a nut, so that the nut of the limiting bolt and the second nut respectively form two limiting protrusions 33 of the first nut.

[0090] In some embodiments, the two limiting protrusions 33 are respectively welded to the two side surfaces of the pin piece 32 in the thickness direction.

[0091] In some embodiments, the two connection blocks 311 of each connector 31 are provided with a pin hole 312, and a pin piece 32 is inserted into the pin hole 312 of the two connection blocks 311 of a connector 31. After the pin piece 32 passes through the pin hole 312, a limiting protrusion 33 is processed.

[0092] In some embodiments, in each connector 31, the pin holes 312 of the two connector blocks 311 have the same size, and the limiting protrusion 33 is limitedly matched with the outer surface of the connector block 311 located at the end of the insertion direction of the pin piece 32. The outer surface of the connector block 311 refers to the surface of the connector block 311 away from the connection groove 310. This arrangement can limit the displacement of the pin piece 32 along its length direction, thereby improving the reliability of the connection between the pin piece 32 and the connector 31.

[0093] In some embodiments, in each connecting head 31, the pin hole 312 of each connecting block 311 is a rectangular hole, and the pin holes 312 of the two connecting blocks 311 are divided into a first pin hole and a second pin hole. The length of the first pin hole is smaller than the length of the second pin hole, and the limiting protrusion 33 is limitedly matched with the inner surface of the connecting block 311 where the first pin hole is located. This arrangement facilitates the disassembly and assembly between the connecting part 10 and the connecting head 31, so as to facilitate the replacement of the worn connecting part 10.

[0094] The inner surface of the connection block 311 refers to the surface of the connection block 311 close to the connection groove 310 .

[0095] See also Figure 5 and Figure 6 In some embodiments, the first connecting plate 11 is provided with two connecting pin holes 1120, and each connecting pin hole 1120 is provided with an avoidance groove 1121 on both sides in the width direction. The size of the connecting pin hole 1120 is the same as the size and shape of the first pin hole. The avoidance groove 1121 is used to avoid the limiting protrusion 33 to facilitate the disassembly and assembly between the connecting member 10 and the connecting head 31, so as to facilitate the replacement of the worn connecting member 10.
