Description

Technical Field

[0001] This invention relates to the field of splice technology, specifically a splice for curtain walls. Background Technology

[0002] Connecting claws, also known as glass claws, mainly serve as support connectors and transfer loads to the fixed support structure system. They are an important component for connecting curtain walls.

[0003] Curtain wall connectors are widely used connection tools in curtain wall technology. Current connector installation methods are relatively complex, as detailed below:

[0004] like Figure 1-3 As shown, a common connecting claw mainly consists of a claw arm 2, a connecting seat 3, and a connecting joint 6. The connecting joint 6 is used to connect to the curtain wall 13. A pressure plate 8 is threaded onto the connecting joint 6, and the pressure plate 8, in conjunction with the connecting joint 6, is used to fix the curtain wall 13 installed on the connecting joint 6. A connecting rod 7 is provided on the connecting joint 6, which can be inserted into and pass through the connecting seat 3. The connecting rod 7 is usually a screw, and a positioning nut 9 and a cap 10 are threaded onto the connecting rod 7. The positioning nut 9 is located on the side of the connecting seat 3 facing the curtain wall 13 (since the operator performs the connection operation on the inside of the connecting claw during installation, for simplicity, the following description will refer to the positioning nut 9 as being installed on the outside of the connecting claw); while the cap 10 is installed on the side away from the curtain wall 13 (i.e., the inside of the connecting claw). After the positioning nut 9 and the end cap 10 clamp the connector 6 together, the connecting rod 7 is fixedly installed on the connector seat 3 to firmly connect the connector 6 and the connector seat 3, so that the entire connector claw can effectively support and fix the curtain wall 13, ensuring the stability and safety of the curtain wall 13 structure.

[0005] Therefore, the positioning nut 9 plays a crucial role in the installation of the curtain wall 13. Its main function is to limit the distance between the connector 3 and the curtain wall 13. When the curtain wall 13 is installed, the workers first adjust the positioning nut 9 to precisely control the distance between the two. Once adjusted, the positioning nut 9 can effectively prevent the curtain wall 13 from moving closer to the connector 3 before the end cap 10 is installed.

[0006] The current conventional installation method involves installing the positioning nut 9 on the outside of the connector 3, which is not on the same side as the end cap 10, resulting in the following shortcomings in the installation process:

[0007] 1. Due to the positional limitations of the positioning nut 9, the commonly used tightening tool is a wrench with jaws on one end (either fixed or adjustable). However, when using this type of wrench to tighten the locking nut 39, the rotation range is limited by the claw arm 2, making it impossible to tighten the locking nut 39 completely. Construction workers need to perform repeated operations to complete the position adjustment of the positioning nut 9, which greatly prolongs the construction time and reduces installation efficiency.

[0008] 2. At the same time, the narrow gap between the connector 3 and the curtain wall 13, the limited operating space and the limited wrench rotation angle further increase the construction difficulty and the risk of operational errors, which is not conducive to the rapid and efficient construction of the curtain wall 13 project.

[0009] 3. The positioning nut 9 is located on the outside of the connector 3. When tightening the positioning nut 9, the installer needs to extend their arm or lean forward significantly. This process not only greatly increases the installer's physical exertion and reduces work efficiency, but also makes it difficult to maintain balance. In dangerous working environments such as high altitudes, this can easily lead to falls due to loss of balance, posing a significant safety hazard.

[0010] 4. Based on the shortcomings of points 2 and 3 above, when the operational difficulty during the installation process increases, the wrench is prone to falling off, which also poses a safety hazard.

[0011] In summary, since the positioning nut 9 is installed on the outside of the connector 3 and is far from the end cap 10, and is separated by the claw arm 2 of the connector claw and the connector 6, the installation is inefficient, inconvenient to operate, and poses safety hazards. Summary of the Invention

[0012] (a) Technical problems to be solved

[0013] To address the shortcomings of existing technologies, this invention provides a connecting claw for curtain walls, which solves the problems of inconvenient installation, low installation efficiency, and safety hazards caused by the installation position of traditional positioning nuts.

[0014] (II) Technical Solution

[0015] To achieve the above objectives, the present invention provides the following technical solution: a curtain wall connector, comprising:

[0016] Connector;

[0017] A claw arm, one end of which is fixedly connected to the connecting seat, and the other end of which is provided with a connecting seat;

[0018] A connector is provided with a connecting rod, which connects to the connector seat. The connector is used for installing curtain walls.

[0019] Its features are:

[0020] A fixed-position locking block is installed on the outer wall of the connecting rod;

[0021] An adjusting component is threadedly connected inside the connector, and a connecting rod passes through the adjusting component laterally. The adjusting component is provided with a locking component that matches the locking block.

[0022] The locking block enters the locking component. When the adjusting component is rotated, the position of the adjusting component changes back and forth within the connector, thereby causing the locking block, connecting rod, and connector to move back and forth synchronously. This is used to adjust the distance between the curtain wall and the connector installed on the connector.

[0023] Furthermore, a cap that is threadedly connected to the connecting rod is installed on the side of the connector away from the connector.

[0024] Furthermore, a screwing component is fixedly provided on the end face of the adjusting component facing the end cap.

[0025] Furthermore, the end cap and the screwing part of the screwing component are of the same model, and the same model of screwing tool is used when screwing them.

[0026] Furthermore, the locking component includes a housing fixedly connected to the adjusting component. The housing has an internal cavity for accommodating the locking block. A blocking part is provided on the side of the housing away from the adjusting component. The blocking part cooperates with the end face of the adjusting component to limit the front and rear movement of the locking block. An opening is provided on the housing for the locking block to enter.

[0027] Furthermore, the housing is arc-shaped, the opening is located at one end of the housing, and the other end of the housing is provided with a limiting part for blocking the blocking block.

[0028] Furthermore, a stop bar is slidably mounted on the adjusting member, one end of which is used to block the locking block to prevent the locking block from coming out of the locking member.

[0029] Furthermore, the adjusting component has a through groove for installing a stop bar. The stop bar is installed in the through groove and passes through the adjusting component. Both ends of the stop bar protrude from the end faces of both ends of the adjusting component. A handle is provided on the end of the stop bar located on the same side as the screwing component.

[0030] Furthermore, a spring is fitted around the outside of the stop rod, and a protruding stop block is provided on the outer wall of the stop rod to block one end of the spring. The adjusting member has an internal mounting groove coaxial with the through groove, the diameter of the mounting groove is larger than the diameter of the through groove, and the outer diameter of the spring is larger than the diameter of the through groove.

[0031] Furthermore, the connector is threadedly connected to a pressure plate, the outer wall of the connector is provided with an external thread, and the inner wall of the pressure plate is provided with an internal thread that matches the external thread on the outer wall of the connector. The pressure plate is installed on the connector and, together with the connector, is used to fix the curtain wall installed on the connector.

[0032] (III) Beneficial Effects

[0033] Compared with the prior art, the present invention provides a connecting claw for curtain walls, which has the following advantages:

[0034] 1. The curtain wall connector claw, through the setting of adjusting parts, locking blocks and engaging parts, allows the operator to adjust the distance between the connector base and the curtain wall by turning the adjusting parts inside the connector base. Since the adjusting parts are threadedly connected to the connector base, after turning the adjusting parts, the position of the adjusting parts inside the connector base changes back and forth (forward and backward displacement), which in turn drives the locking blocks, connecting rods and connectors to move back and forth synchronously, so as to accurately adjust the distance between the curtain wall and the connector base.

[0035] Second, the connecting claw used in this curtain wall, compared with the use of traditional positioning nuts, avoids the cumbersome operation of adjusting the positioning nut on the outside of the connecting seat using a wrench with a jaw on one end. The connecting claw of this patent application can be used to tighten the adjusting part with tools (socket wrench, ordinary wrench, etc.) on the inside of the connecting seat. Since the operation can be performed on the inside of the connecting claw, it is not obstructed by the claw arm and the connecting seat. Therefore, the adjusting part can be tightened in a full circle with tools, which significantly improves the convenience and efficiency of operation.

[0036] Third, the curtain wall uses a connecting claw. Because the adjustment operation is performed inside the connecting seat, this position is not limited by the gap between the connecting seat and the curtain wall. Therefore, it provides ample space for the operator to perform the (tightening) operation. Moreover, the claw arm on the connecting claw and the connecting seat do not obstruct the tightening of the adjustment component. Furthermore, the operator does not need to stretch their arms or lean forward, avoiding the risk of tools (wrenches) falling due to body extension, limited space, or obstruction of the tightening operation by the claw arm and connecting seat. At the same time, it greatly reduces physical exertion, effectively prevents loss of balance, greatly improves the safety of the operation process, reduces the possibility of construction accidents, and makes the curtain wall installation operation safer and more stable, creating a safer working environment for construction personnel.

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Please see Figure 1-3 In the installation system of the curtain wall, the connecting claw is a key connecting component. The existing connecting claw has the following structure and working principle: it includes a connecting seat 1, at least one claw arm 2 installed on the connecting seat 1, one end of the claw arm 2 is fixedly connected to the connecting seat 1, and the other end of the claw arm 2 is provided with a connecting seat 3.

[0057] It also includes a base 4 for installing the connector claws. The base 4 can be firmly fixed to the steel beam by welding, forming an integral connection between the base 4 and the steel beam, ensuring stability under various external forces and resisting adverse factors such as vibration and displacement. Alternatively, other suitable fixing methods can be used to securely install the base 4 onto the building structure, meeting the installation requirements of different building structures. The connector 1 is connected to the base 4 by screws 5. This screw 5 connection method is simple to operate and highly reliable. The tightening force of the screws 5 connects the connector 1 and the base 4 together, achieving a stable connection. This ensures that the connector claws maintain a reliable working condition during long-term use, providing solid support for the curtain wall 13.

[0058] Connector 6 is used to install curtain wall 13. Curtain wall 13 has mounting holes for installing connector 6. Connector 6 is connected to connecting rod 7. Connector 6 is usually located at the end of connecting rod 7. Connector 7 is connected to connector seat 3. Connector 7 can be inserted into connector seat 3 and passes through connector seat 3. Connector 7 is usually a screw. Connector 7 is threadedly connected to positioning nut 9 and end cap 10. Positioning nut 9 is installed on the outside of connector claw (the side closer to connector 6); while end cap 10 is installed on the inside of connector claw (the side away from connector 6).

[0059] During the installation of the curtain wall 13, the main function of the positioning nut 9 is to limit the distance between the connector 3 and the curtain wall 13. When the curtain wall 13 is installed, the staff needs to adjust the positioning nut 9 first to accurately control the distance between the connector 3 and the curtain wall 13. The positioning nut 9 can effectively prevent the curtain wall 13 from moving closer to the connector 3. Then the staff installs the end cap 10. After the end cap 10 and the positioning nut 9 are tightened in place, the two clamp the connector 3 to stably install the connecting rod 7 on the connector 3. The connector claw, connector 6 and the connecting rod 7 that connect the two provide stable support for the installation of the curtain wall 13.

[0060] The connector 6 is connected to a pressure plate 8 by a thread. The outer wall of the connector 6 is provided with an external thread, and the inner wall of the pressure plate 8 is provided with an internal thread that matches the external thread on the outer wall of the connector 6. The pressure plate 8 is installed on the connector 6. After the pressure plate 8 is tightened on the connector 6, the pressure plate 8 cooperates with the connector 6 to fix the curtain wall 13 installed on the connector 6. The end face of the pressure plate 8 is provided with a slot for screwing the pressure plate 8. The pressure plate 8 is screwed using a specified tool.

[0061] like Figure 4-9 As shown, this invention provides a curtain wall connector claw that eliminates the need for the positioning nut 9 on the existing connector claws described in detail above. This invention features a fixed-position locking block 14 installed on the outer wall of the connecting rod 7. "Fixed-position" means that once the locking block 14 is installed on the connecting rod 7 and its position is determined, when an external force is applied to the locking block 14, the force cannot cause the locking block 14 to move along the axis of the connecting rod 7. If the force applied to the locking block 14 causes it to move along the axis of the connecting rod 7, then the adjusting member 15, which will be described in detail later, will not be able to drive the connecting rod 7, connector 6, and curtain wall 13 to move synchronously during the adjustment process. "Fixed-position" means that the position of the locking block 14 on the connecting rod 7 is fixed, but this fixed position does not restrict the locking block 14 from rotating around its own axis.

[0062] The connector 3 has a through hole running through it from front to back. An adjusting member 15 is installed in this hole. The outer wall of the adjusting member 15 has an external thread, and the inner wall of the hole in the connector 3 has an internal thread. The internal thread on the inner wall of the hole in the connector 3 is perfectly matched with the external thread of the adjusting member 15 in terms of parameters such as pitch and thread profile. The connector 3 and the adjusting member 15 are connected by threads. When the adjusting member 15 is rotated, due to the transmission characteristics of the thread, the adjusting member 15 will rotate within the connector 3, thereby adjusting the front and back position of the adjusting member 15 within the connector 3.

[0063] The adjusting member 15 has a through hole 32 for the connecting rod 7 to pass through. The connecting rod 7 passes laterally through the adjusting member 15 through the through hole 32. The adjusting member 15 is provided with a locking member that matches the locking block 14. In use, rotating the adjusting member 15 causes it to move back and forth within the connector 3 (its position changes back and forth). After the locking block 14 enters the locking member, rotating the adjusting member 15 causes the locking member on the adjusting member 15 to move back and forth synchronously. Therefore, the locking block 14 also moves back and forth synchronously with the adjusting member 15, thereby causing the locking block 14, the connecting rod 7, and the connector 6 to move back and forth synchronously. Since the locking block 14 can move back and forth, while the connector 3 does not move back and forth, rotating the adjusting member 15 to move the locking block 14 back and forth can be used to adjust the distance between the curtain wall 13 connected to the connector 6 and the connector 3.

[0064] A screwing element 16 is fixedly provided on the end face of the adjusting member 15 facing the end cap 10 (on the same side as the end cap 10 in the connecting seat 3, i.e., inside the connecting claw). Therefore, the operator can screw the adjusting member 15 from inside the connecting seat 3. Since the screwing element 16 and the end cap 10 are on the same side, operations can be performed on the same side, greatly improving operational convenience. The screwing element 16 is typically designed as a regular polygonal block structure or a grooved structure. A regular polygonal block structure, such as a hexagon, is similar to a common nut and can be used with a conventional wrench; a grooved structure, such as a hexagonal groove, can be adapted to an internal hex wrench, etc. With the help of screwing tools like wrenches, the screwing element 16 can be easily screwed. However, any shape and structure of the screwing element 16 can be used on the adjusting member 15 of this invention, and the connecting rod 7 can pass through the screwing element 16.

[0065] Compared to the traditional positioning nut 9, the tightening component 16 offers significant operational advantages. The adjustment position of the traditional positioning nut 9 is limited by the narrow gap between the connector 3 and the curtain wall 13, and is also easily obstructed by the claw arm 2 and the connector 3, resulting in cramped operating space and significant adjustment difficulty. In contrast, the tightening component 16 is not constrained by the gap between the connector 3 and the curtain wall 13, nor is it hindered by the claw arm 2 and the connector 3. When tightening the adjusting component 15, operators can operate more freely and smoothly, tightening it completely around the entire circle, greatly improving adjustment efficiency and making the entire curtain wall 13 installation process more convenient and efficient, significantly enhancing the practicality of this structure in real-world applications.

[0066] like Figure 6 As shown, to further improve installation efficiency, the screwing parts of the end cap 10 and the screwing component 16 are of the same model. In actual operation, only the same type of screwing tool is needed to screw both parts sequentially. Moreover, their placement on the same side of the connector 3 greatly facilitates operation; after screwing the screwing component 16, the end cap 10 can be screwed immediately without changing tools. The entire installation process is smoother, avoiding the time wasted on changing different tools, and further effectively improving the overall efficiency of the curtain wall 13 installation.

[0067] like Figure 10 As shown, in the first embodiment of the locking component, the locking component includes a circular housing 20 fixedly connected to the adjusting component 15. The housing 20 has an inner cavity 24 for accommodating the locking block 14. The front-to-back distance of the inner cavity 24 is slightly greater than the thickness of the locking block 14. A blocking part 21 is provided on the side of the housing 20 away from the adjusting component 15. The blocking part 21 cooperates with the end face of the adjusting component 15 to limit the front-to-back movement of the locking block 14, so that the locking block 14 can move synchronously with the adjusting component 15 when it is in the inner cavity 24. An opening 22 is provided on the housing 17 for the locking block 14 to enter. The width of the opening 22 is greater than the width of the locking block 14.

[0068] like Figure 11 As shown, in the second embodiment of the locking component, the locking component includes an arc-shaped housing 17 fixedly connected to the adjusting component 15. The housing 17 has an inner cavity 23 for accommodating the locking block 14. The front-to-back distance of the inner cavity 23 is slightly greater than the thickness of the locking block 14. A blocking part 18 is provided on the side of the housing 17 away from the adjusting component 15. The blocking part 18 cooperates with the end face of the adjusting component 15 to limit the front-to-back movement of the locking block 14, so that the locking block 14 can move synchronously with the adjusting component 15 when it is in the inner cavity 23. An opening 19 is provided on the housing 17 for the locking block 14 to enter. The opening 19 is opened at one end of the housing 17. The front-to-back distance of the opening 19 is slightly greater than the thickness of the locking block 14. A limiting part 25 for blocking the locking block 14 is provided at the other end of the housing 17.

[0069] The embodiments of the two engaging components described in this specification are intended to help those skilled in the art understand and implement the relevant technical solutions in an intuitive and visual manner, and are provided for reference only. The technical solutions of this invention are not limited to the two embodiments disclosed above. Any alternative solution that is substantially the same as this invention in technical principles and functional effects and can achieve the same technical purpose should be included within the protection scope of this invention.

[0070] If the locking component of the first embodiment is used, the locking block 14, which is provided on the connecting rod 7, can be fixedly connected to the connecting rod 7. During operation, when the adjusting component 15 is rotated, the housing 20, which is fixedly connected to it, will also rotate synchronously. Since the locking block 14 is fixed to the connecting rod 7, the locking block 14 can rotate freely in the inner cavity 24 of the housing 20. The free rotation of the locking block 14 in the inner cavity 24 of the housing 20 will not hinder the rotation of the adjusting component 15. When the adjusting component 15 moves back and forth, based on the fixed connection between the adjusting component 15 and the housing 20, the locking block 14 in the inner cavity 24 can be driven to move back and forth synchronously, thereby adjusting the position of the locking block 14 and thus adjusting the distance between the connecting seat 3 and the curtain wall 13.

[0071] If the locking component of the first embodiment is used, the connection can also be achieved by rotating the locking block 14 on the connecting rod 7 with the connecting rod 7. When the adjusting component 15 rotates, based on the fixed connection between the adjusting component 15 and the locking component housing 20, whether the locking block 14 rotates in the inner cavity 24 of the housing 20 or not will not affect the forward and backward displacement of the locking block 14 with the housing 20. The position of the locking block 14 on the connecting rod 7 is fixed and will not move along the axial direction of the connecting rod 7. When the adjusting component 15 rotates, its housing 20 drives the locking block 14 to move forward and backward, thereby adjusting the position of the locking block 14 and thus adjusting the distance between the connecting seat 3 and the curtain wall 13.

[0072] If the locking component of the second embodiment is used, since the housing 17 of the locking component is arc-shaped, one end is provided with an opening 19, and the other end is provided with a limiting part 25 for blocking the locking block 14. Based on the structural characteristics of the housing 17, when using the locking component of the second embodiment, the locking block 14 on the connecting rod 7 can only be rotatably connected to the connecting rod 7. When the adjusting member 15 rotates, based on the fixed connection relationship between the adjusting member 15 and the housing 17 of the locking component, the locking block 14 can be driven to rotate. The position of the locking block 14 on the connecting rod 7 is fixed and will not move along the axial direction of the connecting rod 7. When the adjusting member 15 rotates, its housing 17 can drive the locking block 14 located inside the inner cavity 23 to rotate together. At the same time, it can also drive the locking block 14 to move back and forth, realize the back and forth adjustment of the position of the locking block 14, and thus adjust the distance between the connecting seat 3 and the curtain wall 13.

[0073] In this patent, the following two specific embodiments are provided to achieve the rotatable connection between the locking block 14 and the connecting rod 7. It should be clarified that any other technical solutions adopted by those skilled in the art based on the concept and principles of this invention to achieve the rotatable connection between the locking block 14 and the connecting rod 7, regardless of changes in structural form, connection method, or material selection, should be considered to fall within the protection scope of this patent. These implementation methods obtained through equivalent substitution, improvement, or modification are technically consistent with the specific embodiments provided in this patent and are all covered by this patent. Furthermore, in determining infringement, a comprehensive judgment should be made based on the technical content disclosed in the claims and specification of this patent.

[0074] like Figure 7 and 15 As shown, in the first embodiment where the locking block 14 is rotatably connected to the connecting rod 7, a flange 34 is integrally formed or securely fixed on the outer wall of the connecting rod 7. A ring 33 is arranged around the outside of the connecting rod 7. The ring 33 has a groove 35 that precisely matches the flange 34, ensuring a tight and stable connection due to their high fit in size and shape. The locking block 14 is fixedly mounted on the outer wall of the ring 33, and is securely joined to the ring 33 through specific processes such as welding, riveting, high-strength bonding, or integral molding. Therefore, when an external force is applied to the locking block 14, the flange 34 can rotate freely within the groove 35, causing the ring 33 and the locking block 14 to rotate together around the connecting rod 7, achieving a rotatable connection between the locking block 14 and the connecting rod 7. When the locking block 14 is subjected to external force, it can only rotate, while the ring 33 will not move along the axis of the connecting rod 7.

[0075] The connection between the flange 34 and the groove 35 is interchangeable. That is, the flange 34 can also be located on the inner wall of the ring 33, while the groove 35 is located on the outer wall of the connecting rod 7. This reverse arrangement is consistent in principle with the forward arrangement, still utilizing the fitting relationship between the flange 34 and the groove 35. When an external force is applied to the locking block 14 fixed to the outer wall of the ring 33, based on the rotatable characteristic of the flange 34 within the groove 35, the ring 33 drives the locking block 14 to rotate around the connecting rod 7, thus achieving a rotatable connection between the locking block 14 and the connecting rod 7. Both the forward and reverse arrangements provide multiple options for implementing this invention in different application scenarios.

[0076] This connection method is simple and reliable, with advantages such as high practicality and stability. Furthermore, it eliminates the need for excessively long threads to be machined on the connecting rod 7 during machining. Traditional methods of machining long threads on the connecting rod 7 are time-consuming and labor-intensive, increasing processing costs and difficulty. This connection method only requires machining threads at the end of the connecting rod 7 for installing the end cap 10, thus reducing the defect rate that might result from machining long threads.

[0077] However, the drawback is that this connection method requires the ring body 33 and the connecting rod 7 to be processed and installed in advance, and the position of the ring body 33 cannot be adjusted according to actual usage requirements. This means that when faced with diverse usage requirements, it is only possible to meet them by producing products with different specifications of the ring body 33 in different positions.

[0078] It is further important to clarify that during the manufacturing process of the locking block 14, the distance between the outermost end of the locking block 14 and the center of the ring body 33 must be less than the radius of the mounting hole opened on the curtain wall 13. This is because the connecting rod 7 needs to pass through the mounting hole on the curtain wall 13 during installation. If the distance between the outermost end of the locking block 14 and the center of the ring body 33 is greater than the radius of the mounting hole, then due to the presence of the locking block 14, the connecting rod 7 cannot pass through the mounting hole. Once the connecting rod 7 cannot pass through smoothly, the entire connector 6 cannot be installed on the curtain wall 13.

[0079] like Figure 16-17 As shown, in the second embodiment where the locking block 14 is rotatably connected to the connecting rod 7, a mounting nut 36 is threaded onto the connecting rod 7, and a groove 38 is formed on the outer wall of the mounting nut 36. A ring 37 is fitted inside the groove 38, and the ring 37 is rotatably connected to the groove 38, allowing the ring 37 to rotate relative to the groove 38. The locking block 14 is fixedly connected to the ring 37. Once the mounting nut 36 is installed in place on the connecting rod 7, the locking block 14 can only rotate when subjected to external force, while the ring 37 will not move along the axial direction of the connecting rod 7.

[0080] A groove 38 is formed on the outer wall of the mounting nut 36, within which a rotating connecting ring 37 is inserted, achieving a rotatable connection between the locking block 14 and the connecting rod 7. This connection method offers advantages such as simple structure and high flexibility. In use, a traditional connecting rod 7 can be employed. The mounting nut 36 is directly screwed onto the connecting rod 7. When the mounting nut 36 rotates to the pre-set position on the connecting rod 7, the initial installation of the locking block 14 is complete. By tightening the mounting nut 36, the position of the locking block 14 can be adjusted at any time, allowing for flexible changes in its position on the connecting rod 7 according to different needs in actual application scenarios.

[0081] This connection method, compared to previous designs that avoided excessively long threads on the connecting rod 7, required utilizing the longer threads on the traditional connecting rod 7. Therefore, the existing connecting rod 7 of the connector 6 can be directly utilized. Furthermore, this connection method does not have strict limitations on the distance between the locking block 14 and the center of the ring body 37. In actual installation applications, whether the distance between the locking block 14 and the center of the ring body 37 is greater or less than the radius of the mounting hole on the curtain wall 13, it will not affect its normal installation and use.

[0082] To further secure the position of the mounting nut 36, a locking nut 39 can be threaded onto the connecting rod 7. The locking nut 39 is positioned before or after the mounting nut 36 and is tightly fitted to it. The locking nut 39 serves to position the mounting nut 36, effectively preventing it from rotating during use and changing its position on the connecting rod 7.

[0083] When mounting nut 36 and locking nut 39 are assembled onto connecting rod 7, both are connected to the connecting rod 7 via threads. This threaded connection method is based on the principle of a screw pair, that is, utilizing the interlocking threads of the screw and nut, rotating the nut causes it to move along the axial direction of the screw, thereby achieving the function of fastening or adjusting the position. When mounting nut 36 and locking nut 39 are installed on connecting rod 7, they gradually approach each other with rotation until their end faces abut against each other. At this point, due to the tight contact between the end faces of the two nuts, a mutually restrictive mechanical structure is formed. If further attempts are made to rotate mounting nut 36, it will be blocked by the end face of locking nut 39. From a mechanical perspective, locking nut 39 applies a counterforce to mounting nut 36, which prevents further rotation of mounting nut 36. This is analogous to two rigid objects abutting against each other; when a force is applied to one to make it rotate, the resistance of the other object balances this rotational force, thus preventing mounting nut 36 from continuing to rotate, effectively fixing the position of mounting nut 36 on connecting rod 7, and ensuring the stability of the entire connection structure.

[0084] Locking nut 39 and mounting nut 36 are installed on connecting rod 7. To prevent the adjusting member 15 from contacting the locking nut 39 and mounting nut 36 when rotating, the end of the through hole 32 on the adjusting member 15 into which the connecting rod 7 is inserted is designed to have a larger diameter than the diameter of the two nuts. The other end of the through hole 32, which is the end through which the connecting rod 7 protrudes, has an inner diameter that matches the connecting rod 7. The larger diameter insertion end prevents the adjusting member 15 from contacting the mounting nut 36 or locking nut 39, while the matching inner diameter protrusion end can accurately position the connecting rod 7, ensuring the stability of the connecting rod 7 within the through hole 32.

[0085] Based on the above embodiment where the two locking blocks 14 are rotatably connected to the connecting rod 7, when the locking blocks 14 and the connecting rod 7 rotate relative to each other, there is a certain damping force, but this damping force is much smaller than the force of the mounting nut 36 in the second embodiment.

[0086] like Figure 12-14 As shown, to prevent the locking block from dislodging from the engaging component, a stop bar 26 is slidably mounted on the adjusting component 15. One end of the stop bar 26 is used to block the locking block 14. Due to the blocking effect of one end of the stop bar 26 on the locking block 14, the locking block 14 is prevented from dislodging from the engaging component. In a specific embodiment, a through groove 28 for mounting the stop bar 26 is provided on the adjusting component 15. The stop bar 26 is installed in the through groove 28 and passes through the adjusting component 15. Both ends of the stop bar 26 protrude from the end faces of both ends of the adjusting component 15. A handle 27 is provided on the end of the stop bar 26 located on the same side as the screwing component 16, so that the operator can drive the stop bar 26 to change position to switch whether the stop bar 26 blocks the locking block 14.

[0087] The stop lever 26 is fitted with a spring 29. A protruding stop block 30 is provided on the outer wall of the stop lever 26 to block one end of the spring 29. The adjusting member 15 has a mounting groove 31 coaxial with the through groove 28. The diameter of the mounting groove 31 is larger than that of the through groove 28. The outer diameter of the spring 29 is larger than that of the through groove 28. One end of the mounting groove 31 is used to block the other end of the spring 29.

[0088] Spring 29 provides elastic force to stop lever 26 to achieve automatic reset function of stop lever 26. When stop lever 26 is subjected to external force and changes its initial position, the elastic potential energy stored in spring 29 is converted into the force to return stop lever 26 to its original position, ensuring that stop lever 26 can rebound quickly. Under normal conditions without external force, spring 29 continues to function, keeping one end of stop lever 26 in a position that can effectively prevent the locking block 14 from disengaging from the locking member.

[0089] When the stop bar 26 is used to block the locking block 14, it prevents the locking block 14 from coming out of the locking member. Whether using the locking member of the first embodiment or the locking member of the second embodiment, the locking block 14 must be rotatably connected to the connecting rod 7, otherwise the screwing member 16 cannot rotate normally.

[0090] like Figure 2-3As shown, gasket 11 and gasket 2 12 are installed on the connector 6. Gaskets 11 and 2 12 are typically made of rubber, which possesses many excellent properties. Rubber is flexible and elastic, and gaskets 11 and 2 12 play an important role in preventing slippage, increasing the stress area, and providing protection. In actual installation, gasket 11 is installed between the pressure plate 8 and the curtain wall 13. The pressure plate 8 is in direct contact with the curtain wall 13. During the tightening process, without gasket 11, the pressure plate 8 may cause damage to the surface of the curtain wall 13 due to concentrated pressure, and it is also prone to slippage, affecting the fixing effect. Gasket 11 can effectively disperse the pressure applied to the curtain wall 13 by the pressure plate 8, increase the stress area, reduce the pressure per unit area, and prevent damage to the surface of the curtain wall 13; its surface friction can effectively provide good anti-slip properties. Gasket 12 is installed between curtain wall 13 and connector 6, specifically inside the mounting hole of curtain wall 13. When curtain wall 13 is installed on connector 6, the contact area between curtain wall 13 and connector 6 also needs protection and anti-slip properties. Gasket 12 can fill the tiny gap between curtain wall 13 and connector 6, preventing wear caused by direct rigid contact. At the same time, when curtain wall 13 is subjected to external forces, gasket 12 can increase contact friction and improve the stability of the connection.

[0091] like Figure 4-6 As shown, limit covers 40 are fixedly installed at both the front and rear ends of the connector 3. The limit covers 40 are provided with openings for the connecting rod 7 to pass through. The inner diameter of the openings is smaller than the outer diameter of the adjusting member 15, so as to prevent the adjusting member 15 from detaching from the front or rear of the connector 3 due to excessive twisting during the twisting process, and to avoid the adjusting member 15 falling out of the connector 3.

[0092] In summary, this curtain wall uses connector claws, and when using them:

[0093] 1. Pre-installation of curtain wall 13 and connector 6: Install gasket 2 12 on connector 6, then install connector 6 into the mounting hole of curtain wall 13, then install gasket 1 11, and screw pressure plate 8 onto connector 6. The curtain wall 13 is stably fixed by the cooperation of pressure plate 8 and connector 6. Before hoisting curtain wall 13, complete the installation of connector 6 and ensure that the locking block 14 is installed on connecting rod 7.

[0094] 2. Curtain wall 13 hoisting and connecting rod 7 insertion: After hoisting the curtain wall 13 into place, the staff uses tools to insert the connecting rod 7 on the connector 6 into the through hole 32 of the adjusting component 15.

[0095] 3. The locking block 14 engages with the engaging component: As the connecting rod 7 continues to be inserted, after the stop block 30 reaches the position of the adjusting component 15, the adjusting component 15 is slightly rotated to allow the locking block 14 to enter the interior of the engaging component (in the inner cavities 23 and 24 of the housing 17 and 20). Before the locking block 14 enters the interior of the engaging component, the stop rod 26 is pulled inward to allow the end of the stop rod 26 to not obstruct the entry of the locking block 14; once the locking block 14 enters the interior of the engaging component, the stop rod 26 is released so that the end of the stop rod 26 blocks the locking block 14 to prevent the locking block 14 from coming out of the engaging component.

[0096] 4. Spacing adjustment: According to the distance between the curtain wall 13 and the connector 3, the staff rotates the adjusting component 15 and uses a tool to rotate the screw 16. The adjusting component 15 moves back and forth within the connector 3, thereby adjusting the distance between the curtain wall 13 and the connector 3.

[0097] 5. Installation and Fixing of End Cap 10: After adjusting to the appropriate position, screw the end cap 10 onto the connecting rod 7. As the end cap 10 is tightened, the gap between the end cap 10 and the locking block 14 gradually decreases. Finally, the end cap 10 abuts against the inner end face of the connector 3 (if a limit cover 40 is installed, the end cap 10 abuts against the end face of the limit cover 40 located inside the connector 3), and the locking block 14 abuts against the outer end face of the adjusting member 15. The clamping force between the locking block 14 and the end cap 10, acting in conjunction with the force of their mutual approach, fixes the position of the connecting rod 7, completing the connection between the connector 6 and the connector claw.

[0098] 6. Improved installation efficiency: Since the end cap 10 and the screwing part 16 are on the same side and of the same model, they can be screwed using an electric wrench. The traditional positioning nut 9 can only be screwed manually using a wrench with a jaw on one end. Compared with the traditional installation method of positioning nut 9, the position of the adjusting part 15 is closer to the operator, and tools such as electric wrenches can be used to screw it in, which improves installation efficiency and makes the operation more convenient.
