Description

Technical Field

[0001] The invention relates to the technical field of connecting claws, in particular to a connecting claw for curtain walls. Background Art

[0002] The connecting claw, also known as the glass claw, is mainly used as a supporting joint and transfers the load to the fixed supporting structure system. It is an important accessory for connecting the curtain wall.

[0003] Curtain wall joint claws are widely used connection tools in curtain wall technology. The installation method of the joint claws in the prior art is relatively complicated, as follows: like Figure 1-3 As shown, a common docking claw is mainly composed of a claw arm 2, a docking seat 3 and a docking joint 6. The docking joint 6 is used to connect the curtain wall 13. The docking joint 6 is connected with a pressing plate 8 by threading. The pressing plate 8 cooperates with the docking joint 6 to fix the curtain wall 13 installed on the docking joint 6. The docking joint 6 is provided with a connecting rod 7, which can be inserted into the docking seat 3 and penetrate the docking seat 3. The connecting rod 7 is usually a screw rod. The connecting rod 7 is connected with a positioning nut 9 and a head cap 10 by threading. The positioning nut 9 is located on the side of the docking seat 3 facing the curtain wall 13 (because the operator performs the connection operation on the inner side of the docking claw during the installation process, for a simpler description, it is referred to as installing the positioning nut 9 on the outer side of the docking claw in the following); and the head cap 10 is installed on the side away from the curtain wall 13 (i.e., the inner side of the docking claw). After the positioning nut 9 and the end cap 10 cooperate to clamp the docking joint 6, the connecting rod 7 is fixedly installed on the docking seat 3 to firmly connect the docking joint 6 and the docking seat 3, so that the entire docking claw can effectively carry and fix the curtain wall 13, ensuring the stability and safety of the curtain wall 13 structure.

[0004] Therefore, the positioning nut 9 plays a vital role in the installation process of the curtain wall 13. Its main function is to limit the distance between the docking seat 3 and the curtain wall 13. When the curtain wall 13 is installed, the staff first adjusts the positioning nut 9 and uses the positioning nut 9 to accurately control the distance between the two. Once adjusted to the right position, the positioning nut 9 can effectively prevent the curtain wall 13 from moving closer to the docking seat 3, and then install the end cap 10.

[0005] Since the conventional installation method is to install the positioning nut 9 on the outside of the docking seat 3, which is not on the same side as the head cap 10, the installation process has the following shortcomings: 1. Due to the position limitation of the positioning nut 9, a wrench with a jaw at one end (with a fixed jaw or an adjustable jaw) is often used as a screwing tool. However, when using this wrench to screw the locking nut 39, the rotation range is limited by the claw arm 2 each time, and the locking nut 39 cannot be screwed in a full circle. The construction personnel need to repeat the operation many times to complete the position adjustment of the positioning nut 9, which greatly prolongs the construction time and reduces the installation efficiency.

[0006] 2. At the same time, the distance between the docking seat 3 and the curtain wall 13 is narrow, the narrow operating space and the limited wrench rotation angle further increase the construction difficulty and the risk of operating errors, which is not conducive to the rapid and efficient construction of the curtain wall 13 project.

[0007] 3. The positioning nut 9 is located outside the docking seat 3. When the installer screws the positioning nut 9, he needs to stretch his arms or lean forward to operate. This process not only greatly increases the physical exertion of the installer, resulting in reduced work efficiency, but also makes it difficult to maintain the balance of the body's center of gravity. In dangerous working environments such as high altitudes, it is very easy to fall due to body imbalance, which poses a great safety hazard.

[0008] 4. Based on the deficiencies of points 2 and 3 above, when the difficulty of operation during the installation process increases, the wrench is prone to fall, which also poses a safety hazard.

[0009] To sum up, since the installation position of the positioning nut 9 is on the outside of the docking seat 3 and the distance from the head cap 10 is relatively far, and there are also the claw arm 2 of the docking claw and the docking joint 6 in between, there are shortcomings such as low efficiency, inconvenience in operation, and safety hazards during installation. Summary of the invention

[0010] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a curtain wall docking claw to solve the problems of inconvenience in installation, low installation efficiency, potential safety hazards, etc. caused by the installation position of the traditional positioning nut.

[0012] Furthermore, a head cap threadedly connected to the connecting rod is installed on the side of the docking seat away from the docking head.

[0013] Furthermore, a screwing piece is fixedly provided on the end surface of the adjusting piece facing the head cap.

[0014] Furthermore, the screwing parts of the head cap and the screwing member are of the same model, and when the two are screwed, the same model of screwing tool is used for screwing.

[0015] Furthermore, the engaging member includes a shell fixedly connected to the adjusting member, the interior of the shell is provided with an inner cavity for accommodating the card block, a blocking portion is provided on the side of the shell away from the adjusting member, the blocking portion cooperates with the end face of the adjusting member to limit the front and rear positions of the card block, and an opening is provided on the shell for the card block to enter.

[0016] Furthermore, the shell is arranged in an arc shape, the opening is provided at one end of the shell, and the other end of the shell is provided with a limiting portion for blocking the block.

[0017] Furthermore, a blocking rod is slidably mounted on the adjusting member, and one end of the blocking rod is used to block the card block to prevent the card block from escaping from the inside of the engaging member.

[0018] Furthermore, the adjusting member is provided with a through slot for installing a baffle rod, the baffle rod is installed in the through slot, the baffle rod passes through the adjusting member through the through slot, both ends of the baffle rod protrude from the end surfaces of the adjusting member, and a handle is provided on the end of the baffle rod on the same side as the screwing member.

[0019] Furthermore, a spring is mounted on the outside of the baffle rod, and a raised block is provided on the outer wall of the baffle rod for blocking one end of the spring. A mounting groove coaxial with the through groove is provided inside the adjusting member, and 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.

[0020] Furthermore, a pressing plate is threadedly connected to the dock joint, an external thread is arranged on the outer wall of the dock joint, an internal thread matching the external thread on the outer wall of the dock joint is arranged on the inner wall of the pressing plate, the pressing plate is installed on the dock joint, and the pressing plate cooperates with the dock joint to fix the curtain wall installed on the dock joint.

[0021] (III) Beneficial effects Compared with the prior art, the present invention provides a curtain wall connection claw, which has the following beneficial effects: 1. The curtain wall docking claw, through the arrangement of the adjusting piece, the clamping block and the engaging piece, when the staff adjusts the distance between the docking seat and the curtain wall, the docking claw of the patent application can screw the adjusting piece on the inner side of the docking seat. Since the adjusting piece is threadedly connected to the docking seat, after screwing the adjusting piece, the position of the adjusting piece in the docking seat changes forward and backward (forward and backward displacement), thereby driving the clamping block, the connecting rod and the docking joint to move forward and backward synchronously, so as to accurately adjust the distance between the curtain wall and the docking seat.

[0022] 2. Compared with the use of traditional positioning nuts, the coupling claw for the curtain wall avoids the cumbersome operation of adjusting the positioning nut on the outside of the docking seat with a wrench with a jaw on one end. The coupling claw of the present patent application can be used to screw the adjusting piece with a tool (socket wrench, ordinary wrench, etc.) on the inside of the docking seat. Since the operation can be performed on the inside of the coupling claw without being hindered by the claw arm and the docking seat, the adjusting piece can be screwed in a full circle using a tool, thereby significantly improving the convenience and efficiency of the operation.

[0023] 3. The curtain wall docking claw is used for adjustment operation on the inside of the docking seat, which is not limited by the gap between the docking seat and the curtain wall. Therefore, it provides sufficient space for the workers to operate (twisting), and the claw arm and docking seat on the docking claw will not hinder the screwing of the adjustment parts. In addition, the workers do not need to stretch their arms or lean forward, avoiding the risk of the tool (wrench) falling out of their hands due to body extension, narrow space, claw arms and docking seats hindering the screwing work, etc. At the same time, it greatly reduces physical exertion, effectively prevents the occurrence of body imbalance, greatly improves the safety of the operation process, reduces the possibility of construction accidents, makes curtain wall installation operations safer and more stable, and creates a safer working environment for construction workers.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-3 In the installation system of the curtain wall, the docking claw is a key connecting component. The docking claw in the prior art has the following structure and working principle, including 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 docking seat 3; It also includes a base 4 for installing the docking claw, which can be firmly fixed to the steel beam by welding, and the base 4 is connected to the steel beam in one piece by welding technology, ensuring that it can remain stable under various external forces and resist adverse factors such as vibration and displacement; the base 4 can also be firmly installed on the building body by other suitable fixing means to meet the installation requirements of different building structures. The connecting seat 1 is connected to the base 4 by screws 5. This screw 5 connection method is easy to operate and has high reliability. The fastening force of the screw 5 is used to connect the connecting seat 1 and the base 4 together to achieve a stable connection between the two. Ensure that the docking claw always maintains a reliable working state during long-term use, providing solid support for the curtain wall 13.

[0027] The docking joint 6 is used to install the curtain wall 13. The curtain wall 13 is provided with a mounting hole for installing the docking joint 6. The docking joint 6 is connected with a connecting rod 7. Usually, the docking joint 6 is arranged at the end of the connecting rod 7. The connecting rod 7 is connected to the docking seat 3. The connecting rod 7 can be inserted into the docking seat 3 and penetrate the docking seat 3. The connecting rod 7 is usually a screw. The connecting rod 7 is connected with a positioning nut 9 and a head cap 10 through a thread. The positioning nut 9 is installed on the outside of the docking claw (the side close to the docking joint 6); and the head cap 10 is installed on the inside of the docking claw (the side away from the docking joint 6); During the installation of the curtain wall 13, the main function of the positioning nut 9 is to limit the distance between the docking seat 3 and the curtain wall 13. When the curtain wall 13 is installed, the staff needs to adjust the positioning nut 9 first, and use the positioning nut 9 to accurately control the distance between the docking seat 3 and the curtain wall 13. The positioning nut 9 can effectively prevent the curtain wall 13 from moving toward the docking seat 3. Then the staff installs the head cap 10. After the head cap 10 and the positioning nut 9 are tightened in place, the two clamp the docking seat 3 to stably install the connecting rod 7 on the docking seat 3. The docking claw, docking joint 6 and the connecting rod 7 connecting the two provide stable support for the installation of the curtain wall 13.

[0028] A pressing piece 8 is connected to the dock joint 6 through a thread, an outer wall of the dock joint 6 is provided with an external thread, and an inner wall of the pressing piece 8 is provided with an internal thread matching the external thread on the outer wall of the dock joint 6. The pressing piece 8 is installed on the dock joint 6. After the pressing piece 8 is tightened on the dock joint 6, the pressing piece 8 cooperates with the dock joint 6 to fix the curtain wall 13 installed on the dock joint 6. A slot hole for screwing the pressing piece 8 is provided on the end face of the pressing piece 8, and the pressing piece 8 is screwed using a designated tool.

[0029] like Figure 4-9 As shown, a curtain wall docking claw of the present invention abandons the setting of the positioning nut 9 on the existing docking claw described in detail above. The present invention installs a fixed position block 14 on the outer wall of the connecting rod 7. The so-called fixed position means that once the block 14 is installed on the connecting rod 7 and the position is determined, when an external force acts on the block 14, the force acting on the block 14 cannot make the block 14 move along the axis of the connecting rod 7. If the force acting on the block 14 makes the block 14 move along the axis of the connecting rod 7, the adjustment member 15 described in detail later cannot drive the connecting rod 7, the docking joint 6 and the curtain wall 13 to move synchronously during the adjustment process. Fixed position means that the position of the block 14 on the connecting rod 7 is fixed, but the fixed position does not restrict the block 14 from rotating around its own axis.

[0030] The docking seat 3 is provided with a hole that penetrates the docking seat 3 from front to back, and an adjusting member 15 is installed in the hole. An external thread is provided on the outer wall of the adjusting member 15, and an internal thread is provided on the inner wall of the hole of the docking seat 3. The internal thread on the inner wall of the hole of the docking seat 3 completely matches the external thread of the adjusting member 15 in terms of pitch, thread tooth type and other parameters, and the docking seat 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 in the docking seat 3 during the rotation process, so that the front and rear position of the adjusting member 15 in the docking seat 3 can be adjusted.

[0031] The adjusting member 15 is provided with a through hole 32 for the connecting rod 7 to pass through. The connecting rod 7 passes through the adjusting member 15 transversely through the through hole 32. The adjusting member 15 is provided with a snap-fitting piece that matches the clamping piece 14. When in use, the adjusting member 15 is rotated, and the adjusting member 15 is displaced forward and backward in the docking seat 3 (the position changes forward and backward). After the clamping piece 14 enters the inside of the snap-fitting piece, the snap-fitting piece on the adjusting member 15 is synchronously displaced forward and backward when the adjusting member 15 is rotated, so the clamping piece 14 is also synchronously displaced forward and backward with the adjusting member 15, thereby driving the clamping piece 14, the connecting rod 7 and the docking head 6 to move forward and backward synchronously. Since the clamping piece 14 can move forward and backward, while the docking head 3 will not move forward and backward, when the adjusting member 15 is rotated to drive the clamping piece 14 to move forward and backward, it can be used to adjust the distance between the curtain wall 13 connected to the docking head 6 and the docking head 3.

[0032] A screwing piece 16 is fixedly provided on the end surface of the adjusting piece 15 facing the side of the end cap 10 (on the same side of the docking seat 3 as the end cap 10, i.e., on the inner side of the docking claw). Therefore, the staff can screw the adjusting piece 15 on the inner side of the docking seat 3, and since the screwing piece 16 and the end cap 10 are on the same side, they can be operated on the same side, which greatly improves the convenience of operation. The screwing piece 16 is usually designed as a regular polygon block structure or a groove structure. The regular polygon block structure, such as a hexagon, is similar to an ordinary nut and can be used with a conventional wrench; the groove structure is a hexagonal groove, etc., which can be adapted to an Allen wrench, etc. With the help of a screwing tool such as a wrench, the screwing piece 16 can be easily screwed. However, screwing pieces 16 of any shape and structure can be used on the adjusting piece 15 of the present invention, and the connecting rod 7 can pass through the screwing piece 16.

[0033] Compared with the traditional positioning nut 9, the operating advantage of the screwing member 16 is very obvious. The adjustment position of the traditional positioning nut 9 is limited by the narrow gap between the docking seat 3 and the curtain wall 13, and is also easily blocked by the claw arm 2 and the docking seat 3, resulting in a cramped operating space and greater difficulty in adjustment. The screwing position of the screwing member 16 is not restricted by the gap between the docking seat 3 and the curtain wall 13, nor will it be hindered by the claw arm 2 and the docking seat 3. When screwing the adjustment member 15, the staff can operate more freely and smoothly, and can tighten the adjustment member 15 in a full circle, which greatly improves the adjustment efficiency, makes the entire curtain wall 13 installation process more convenient and efficient, and greatly enhances the practicality of the structure in actual applications.

[0034] like Figure 6 As shown, in order to further improve the installation efficiency, the screwing parts of the end cap 10 and the screwing piece 16 are set to the same model. In actual operation, only the same model of screwing tools are needed to screw the two in sequence. Moreover, they are set on the same side of the docking seat 3, which greatly facilitates the operation of the staff. After the screwing work of the screwing piece 16 is completed, the end cap 10 can be screwed immediately without changing tools. The entire installation process is smoother, avoiding the time spent on changing different tools, and further effectively improving the overall efficiency of the curtain wall 13 installation.

[0035] like Fig.10As shown, the first embodiment of the engaging member, the engaging member includes a circular shell 20 fixedly connected to the adjusting member 15, the interior of the shell 20 is provided with an inner cavity 24 for accommodating the card block 14, the front and rear spacing of the inner cavity 24 is slightly larger than the thickness of the card block 14, and a blocking portion 21 is provided on the side of the shell 20 away from the adjusting member 15. The blocking portion 21 cooperates with the end surface of the adjusting member 15 to limit the front and rear of the card block 14, so that the card block 14 can be synchronously displaced forward and backward with the adjusting member 15 when in the inner cavity 24, and an opening 22 for the card block 14 to enter is opened on the shell 17, and the width of the opening 22 is larger than the width of the card block 14.

[0036] like Fig.11 As shown, a second embodiment of the engaging member, the engaging member includes a shell 17 which is fixedly connected to the adjusting member 15 and is an arc-shaped shell as a whole, an inner cavity 23 for accommodating the card block 14 is arranged inside the shell 17, and the front-to-back spacing of the inner cavity 23 is slightly larger than the thickness of the card block 14, and a blocking portion 18 is arranged on the side of the shell 17 away from the adjusting member 15, and the blocking portion 18 cooperates with the end surface of the adjusting member 15 to limit the front and back of the card block 14, so that the card block 14 can be synchronously displaced front and back with the adjusting member 15 when in the inner cavity 23, and an opening 19 for the card block 14 to enter is opened on the shell 17, and the opening 19 is opened at one end of the shell 17, and the front-to-back spacing of the opening 19 is slightly larger than the thickness of the card block 14, and a limiting portion 25 for blocking the card block 14 is arranged at the other end of the shell 17.

[0037] The above two embodiments of the engaging parts described in this specification are intended to help those skilled in the art understand and implement the relevant technical solutions in an intuitive and vivid way for reference. The technical solution of the present invention is not limited to the two implementation scenarios disclosed above. Any alternative solutions that are essentially the same as the present invention in terms of technical principles and functional effects and can achieve the same technical purpose should be included in the protection scope of the present invention.

[0038] If the engaging member of the first embodiment is adopted, the block 14 disposed on the connecting rod 7 can be fixedly connected to the connecting rod 7. During operation, when the adjusting member 15 is rotated, the housing 20 fixedly connected thereto will also rotate synchronously. Since the block 14 is fixed to the connecting rod 7, the block 14 can rotate freely in the inner cavity 24 of the housing 20, and the free rotation of the block 14 in the inner cavity 24 of the housing 20 will not hinder the rotation of the adjusting member 15. When the adjusting member 15 moves forward and backward, based on the fixed connection relationship between the adjusting member 15 and the housing 20, the block 14 in the inner cavity 24 can be driven to move forward and backward synchronously, so as to adjust the position of the block 14 forward and backward, and then adjust the distance between the docking seat 3 and the curtain wall 13.

[0039] If the engaging member of the first embodiment is adopted, the block 14 on the connecting rod 7 can also be connected by rotating with the connecting rod 7. When the adjusting member 15 rotates, based on the fixed connection relationship between the adjusting member 15 and the engaging member housing 20, the rotation of the block 14 in the inner cavity 24 of the housing 20 will not affect the forward and backward displacement of the block 14 with the housing 20. The position of the block 14 on the connecting rod 7 is fixed and will not move along the axis direction of the connecting rod 7. When the adjusting member 15 rotates, its housing 20 drives the block 14 to move forward and backward, so as to adjust the position of the block 14 forward and backward, and then adjust the distance between the docking seat 3 and the curtain wall 13.

[0040] If the engaging member of the second embodiment is adopted, since the housing 17 of the engaging member is arc-shaped, an opening 19 is provided at one end, and a limiting portion 25 for blocking the block 14 is provided at the other end. Based on the structural characteristics of the housing 17, when the engaging member of the second embodiment is used, the block 14 on the connecting rod 7 can only be rotatably connected with the connecting rod 7. When the adjusting member 15 rotates, based on the fixed connection relationship between the adjusting member 15 and the engaging member housing 17, the block 14 can be driven to rotate. The position of the block 14 on the connecting rod 7 is fixed and will not move along the axis direction of the connecting rod 7. When the adjusting member 15 rotates, its housing 17 can drive the block 14 located inside the inner cavity 23 to rotate together. At the same time, it can also drive the block 14 to move forward and backward, so as to adjust the position of the block 14 forward and backward, and then adjust the distance between the docking seat 3 and the curtain wall 13.

[0041] In this patent, the following two specific embodiments are provided to realize the rotational connection between the block 14 and the connecting rod 7. It should be clear that any other technical solutions adopted by those skilled in the art based on the concept and principle of the present invention that can achieve the rotational connection between the block 14 and the connecting rod 7, regardless of how the structural form, connection method, material selection, etc. change, should be deemed to fall within the scope of protection of this patent. These implementation methods obtained by means of equivalent replacement, improvement, deformation, etc. are consistent with the specific embodiments provided by this patent in technical essence, and are all covered by this patent, and when judging infringement, a comprehensive judgment should be made based on the claims of this patent and the technical content disclosed in the specification.

[0042] like Figure 7 and 15As shown, the first embodiment of the block 14 being rotatably connected with the connecting rod 7, on the outer wall of the connecting rod 7, a circle of flange body 34 is formed in one piece or by a firmly fixed manner. On the outside of the connecting rod 7, an annular sleeve body 33 is arranged around. The inside of the annular sleeve body 33 is provided with a groove 35 that is precisely matched with the flange body 34, and the two are highly matched in size and shape, ensuring the tightness and stability of the connection. The block 14 is then arranged on the outer wall of the annular sleeve body 33 in a fixed manner, and through specific processes such as welding, riveting, high-strength bonding or integral molding, the block 14 is firmly combined with the annular sleeve body 33. Therefore, when an external force acts on the block 14, because the flange body 34 can rotate freely in the groove 35, the annular sleeve body 33 is driven to rotate around the connecting rod 7 together with the block 14, realizing the rotational connection between the block 14 and the connecting rod 7, the block 14 can only rotate when subjected to an external force, and the annular sleeve body 33 will not move along the axial direction of the connecting rod 7.

[0043] The connection relationship between the flange body 34 and the groove 35 can be flexibly interchanged. That is, the flange body 34 can also be set on the inner wall of the annular sleeve body 33, and at the same time, the groove 35 is opened on the outer wall of the connecting rod 7. This reverse setting is consistent with the forward setting in principle, and still utilizes the adaptation relationship between the flange body 34 and the groove 35. When an external force is applied to the block 14 fixed on the outer wall of the annular sleeve body 33, based on the rotatable characteristics of the flange body 34 in the groove 35, the annular sleeve body 33 drives the block 14 to rotate around the connecting rod 7, and also achieves a rotational connection between the block 14 and the connecting rod 7. Whether it is a forward setting or a reverse setting, it provides a variety of options for the implementation of the present invention in different application scenarios.

[0044] This connection method has the advantages of simple structure, reliability, high practicality and stability, etc., and when processing the connecting rod 7, there is no need to process too long threads on the rod body of the connecting rod 7. The processing of long threads on the traditional connecting rod 7 is time-consuming and labor-intensive, which increases the processing cost and difficulty. However, this connection method only requires processing threads for installing the end cap 10 at the end of the connecting rod 7, which also reduces the defective rate that may be caused by processing long threads.

[0045] However, the disadvantage of this connection method is that the ring sleeve 33 and the connecting rod 7 need to be processed and installed in advance, and the position of the ring sleeve 33 cannot be adjusted according to actual usage requirements. This results in that when faced with diverse usage requirements, it can only be met by producing a variety of products with ring sleeves 33 in different positions and specifications.

[0046] It is necessary to further explain that during the processing of the block 14, the distance between the outermost end of the block 14 and the center of the annular sleeve body 33 must be smaller than the radius of the mounting hole opened on the curtain wall 13. During the installation process, the connecting rod 7 needs to pass through the mounting hole on the curtain wall 13. If the distance between the outermost end of the block 14 and the center of the annular sleeve body 33 is larger than the radius of the mounting hole, the connecting rod 7 cannot pass through the mounting hole due to the existence of the block 14. Once the connecting rod 7 cannot pass through smoothly, the entire docking joint 6 cannot be installed on the curtain wall 13.

[0047] like Figure 16-17 As shown, the second embodiment in which the block 14 is rotatably connected to the connecting rod 7, the connecting rod 7 is threadedly connected with a mounting nut 36, and a groove 38 is provided on the outer wall of the mounting nut 36. An annular sleeve body 37 is sleeved inside the groove 38, and the annular sleeve body 37 is rotatably connected to the groove 38, so that the annular sleeve body 37 can rotate relative to the groove 38. The block 14 is fixedly connected to the annular sleeve body 37. Once the mounting nut 36 is installed in place on the connecting rod 7, the block 14 can only rotate when subjected to an external force, and the annular sleeve body 37 will not move along the axial direction of the connecting rod 7.

[0048] By providing a groove 38 on the outer wall of the mounting nut 36 and rotating the connecting ring sleeve 37 in the groove 38, the rotational connection between the block 14 and the connecting rod 7 is achieved. This connection method has the advantages of simple structure and high flexibility. When in use, a traditional connecting rod 7 can be used. The mounting nut 36 is directly screwed on the connecting rod 7. When the mounting nut 36 is rotated to a predetermined position on the connecting rod 7, the installation of the block 14 is initially completed. By screwing the mounting nut 36, the position of the block 14 can be adjusted at any time, so that the position of the block 14 on the connecting rod 7 can be flexibly changed according to the different needs of the actual use scenario.

[0049] Compared with the previous design of avoiding too long threads on the connecting rod 7, this connection method needs to use the longer threads on the traditional connecting rod 7. Therefore, the connecting rod 7 of the existing docking joint 6 can be directly used. In addition, in this connection method, there is no strict restriction on the distance between the block 14 and the center of the annular sleeve 37. In the actual installation application scenario, whether the center distance between the block 14 and the annular sleeve 37 is larger than the radius of the installation hole on the curtain wall 13 or smaller than the radius of the installation hole, it will not affect its normal installation and use.

[0050] In order to further stabilize the position of the mounting nut 36, a locking nut 39 can be threadedly installed on the connecting rod 7. The installation position of the locking nut 39 is in front of and behind the mounting nut 36, and is close to the mounting nut 36. The locking nut 39 plays a role in positioning the mounting nut 36. When the locking nut 39 is installed in place, it can effectively prevent the mounting nut 36 from rotating during use and changing its position on the connecting rod 7.

[0051] When the mounting nut 36 and the locking nut 39 are assembled on the connecting rod 7, both are connected to the connecting rod 7 through threads. This threaded connection method is based on the principle of a screw pair, that is, the threads of the screw and the nut are meshed with each other, and the nut is rotated to move along the axial direction of the screw, thereby realizing the function of tightening or adjusting the position. When the mounting nut 36 and the locking nut 39 are installed on the connecting rod 7, the two are gradually approached with the rotation operation until their end faces abut against each other. At this time, due to the close contact between the end faces of the two nuts, a mutually restraining mechanical structure is formed. If you continue to try to rotate the mounting nut 36, you will be blocked by the end face of the locking nut 39. From the perspective of mechanical principles, the locking nut 39 applies a reverse force to the mounting nut 36, which prevents the mounting nut 36 from rotating further. This is like two rigid objects abutting against each other. When a force is applied to one of them to make it rotate, the resistance of the other object will balance the rotational force, so that the mounting nut 36 cannot continue to rotate, effectively fixing the position of the mounting nut 36 on the connecting rod 7 and ensuring the stability of the entire connection structure.

[0052] The locking nut 39 and the mounting nut 36 are mounted on the connecting rod 7. In order to prevent the adjusting member 15 from contacting the locking nut 39 and the mounting nut 36 when the adjusting member 15 rotates, the end of the through hole 32 on the adjusting member 15 for inserting the connecting rod 7 is designed to have a larger diameter, which is larger than the diameters of the two nuts, while the other end of the through hole 32, that is, the end through which the connecting rod 7 passes, is designed to have 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 the locking nut 39, while the matching inner diameter passing end can accurately position the connecting rod 7 and ensure the stability of the connecting rod 7 in the through hole 32.

[0053] Based on the above two embodiments in which the clamping block 14 is rotatably connected to the connecting rod 7, when the clamping block 14 and the connecting rod 7 rotate relative to each other, there is a certain damping force, but the damping force is much smaller than the force for rotating the mounting nut 36 in the second embodiment.

[0054] like Figure 12-14As shown, in order to prevent the block from falling out of the engaging member, a blocking rod 26 is slidably installed on the adjusting member 15, and one end of the blocking rod 26 is used to block the block 14. Since one end of the blocking rod 26 blocks the block 14, the block 14 is prevented from falling out of the engaging member. In a specific embodiment, a through slot 28 for installing the blocking rod 26 is provided on the adjusting member 15, and the blocking rod 26 is installed in the through slot 28. The blocking rod 26 passes through the adjusting member 15 from the through slot 28, and both ends of the blocking rod 26 protrude from the end surfaces of both ends of the adjusting member 15. A handle 27 is provided on the end of the blocking rod 26 located on the same side as the screwing member 16, so that the staff can drive the blocking rod 26 to move, so as to switch whether the blocking rod 26 blocks the block 14.

[0055] A spring 29 is sleeved on the outside of the blocking rod 26, and a protruding block 30 is provided on the outer wall of the blocking rod 26 for blocking one end of the spring 29. A mounting groove 31 coaxial with the through groove 28 is provided inside the adjusting member 15. The diameter of the mounting groove 31 is larger than the through groove 28, and the outer diameter of the spring 29 is larger than the diameter of the through groove 28. One end of the mounting groove 31 is used to block the other end of the spring 29.

[0056] The spring 29 can provide elastic force for the blocking rod 26 to realize the automatic reset function of the blocking rod 26. When the blocking rod 26 is subjected to an external force and changes its initial position, the elastic potential energy stored in the spring 29 will be converted into a power to return the blocking rod 26 to its original position, ensuring that the blocking rod 26 can rebound quickly. In the normal state without external force, the spring 29 continues to play a role, so that one end of the blocking rod 26 is always kept in a position that can effectively prevent the block 14 from escaping from the engaging member.

[0057] When the blocking rod 26 is used to block the block 14, the block 14 is prevented from coming out of the engaging member. Whether the engaging member of the first embodiment or the engaging member of the second embodiment is used, the block 14 needs to be rotatably connected to the connecting rod 7, otherwise the screwing member 16 cannot rotate normally.

[0058] like Figure 2-3As shown, a gasket 11 and a gasket 2 12 are installed on the docking joint 6. The gasket 11 and the gasket 2 12 are usually made of rubber material, which has many excellent properties. The rubber material is flexible and has a certain elasticity. The gasket 11 and the gasket 2 12 play an important role in anti-slip, increasing the force-bearing area and protection. During the actual installation, the gasket 11 is installed between the pressing plate 8 and the curtain wall 13. The pressing plate 8 is in direct contact with the curtain wall 13. During the tightening process, if there is no gasket 11, the pressing plate 8 may cause damage to the surface of the curtain wall 13 due to concentrated pressure, and it is also easy to slip, affecting the fixing effect. The gasket 11 can effectively disperse the pressure applied by the pressing plate 8 to the curtain wall 13, expand the force-bearing area, reduce the pressure per unit area, and avoid damage to the surface of the curtain wall 13; the friction force on its surface can effectively play a good anti-slip role. The second gasket 12 is installed between the curtain wall 13 and the docking joint 6, that is, in the installation hole of the curtain wall 13. When the curtain wall 13 is installed on the docking joint 6, the contact part between the curtain wall 13 and the docking joint 6 also needs to be protected and non-slip. The second gasket 12 can fill the small gap between the curtain wall 13 and the docking joint 6 to prevent the two from wearing due to direct rigid contact; at the same time, when the curtain wall 13 is subjected to external force, the second gasket 12 can increase the contact friction and improve the stability of the connection.

[0059] like Figure 4-6 As shown, limit covers 40 are fixedly provided at both the front and rear ends of the docking seat 3. The limit cover 40 is provided with a through hole for the connecting rod 7 to pass through. The inner diameter of the through hole is smaller than the outer diameter of the adjusting member 15, thereby preventing the adjusting member 15 from detaching from the front or rear of the docking seat 3 due to excessive screwing during the screwing process, and avoiding the adjusting member 15 from falling out of the docking seat 3.

[0060] In summary, when the curtain wall connection claw is used: 1. Pre-installation of curtain wall 13 and docking joint 6: Install gasket 2 12 on docking joint 6, then install docking joint 6 in the installation hole of curtain wall 13, then install gasket 11, screw pressure piece 8 onto docking joint 6, and use pressure piece 8 and docking joint 6 to stably fix curtain wall 13. Before hoisting curtain wall 13, complete the installation of docking joint 6 and ensure that the block 14 has been installed on connecting rod 7.

[0061] 2. Hoisting of the curtain wall 13 and insertion of the connecting rod 7: The curtain wall 13 is hoisted in place, and the staff uses a tool to insert the connecting rod 7 on the docking joint 6 into the through hole 32 of the adjusting member 15.

[0062] 3. The block 14 is inserted into the engaging part: As the connecting rod 7 is continuously inserted, after the block 30 reaches the position of the adjusting part 15, the adjusting part 15 is rotated in a small range to allow the block 14 to enter the inside of the engaging part (in the inner cavity 23; 24 of the housing 17; 20). Before the block 14 enters the inside of the engaging part, the blocking rod 26 is pulled inward to allow the end of the blocking rod 26 to not block the entry of the block 14; once the block 14 enters the inside of the engaging part, the blocking rod 26 is released to allow the end of the blocking rod 26 to block the block 14 to prevent the block 14 from falling out of the engaging part.

[0063] 4. Spacing adjustment: The staff rotates the adjusting member 15 according to the spacing between the curtain wall 13 and the docking seat 3, and rotates the screw member 16 through a tool, so that the adjusting member 15 moves forward and backward in the docking seat 3, thereby adjusting the spacing between the curtain wall 13 and the docking seat 3.

[0064] 5. Installation and fixation of the 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 distance between the end cap 10 and the clamping block 14 gradually decreases. Finally, the end cap 10 abuts against the end face on the inner side of the docking seat 3 (if a limit cover 40 is installed, the end cap 10 abuts against the end face of the limit cover 40 located on the inner side of the docking seat 3), and the clamping block 14 abuts against the end face on the outer side of the adjusting member 15. The clamping block 14 cooperates with the force of the end cap 10 approaching each other, and the clamping force between the two fixes the position of the connecting rod 7, completing the connection between the docking head 6 and the docking claw.

[0065] 6. Improve installation efficiency: Since the head cap 10 and the screw part 16 are on the same side and have the same model, they can be screwed with an electric wrench. The traditional positioning nut 9 can only be manually screwed with a wrench with a jaw on one end. Compared with the installation method of the traditional positioning nut 9, the position of the adjustment part 15 is closer to the staff, and electric and other convenient screwing tools can be used, which improves installation efficiency and makes operation more convenient.
