Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of curtain wall splicing, in particular to a unit curtain wall splicing device. BACKGROUND

[0002] The curtain wall is a kind of building envelope structure, which is usually composed of panels (such as glass, metal plate, stone, etc.) and supporting structure (such as aluminum alloy frame), and has the characteristics of beauty, energy saving, light weight, etc. During construction, multiple curtain walls are arranged according to position, and corresponding connecting pieces are used to connect between adjacent two curtain walls to ensure stability.

[0003] After searching, the related patents for curtain wall splicing are as follows:

[0004] Unit curtain wall splicing device and unit curtain wall splicing device, publication number: CN204826328U, the connecting member includes a vertical part and two horizontal parts, the two horizontal parts are tightly connected at both ends of the vertical part, and the two horizontal parts each have a same bending angle B, and the angle of the bending angle B is the same as the included angle A. Among them, the vertical part can be a rod-shaped profile, the horizontal part includes a bending plate with a bending angle B, and the two ends of the bending plate are tightly connected with extension profiles, in practice, the two extension profiles can be tightly connected on both sides of the bending plate through screws, thereby forming a horizontal part. The two horizontal parts can be tightly connected at both ends of the vertical part. During construction and installation, only the bending plate with different bending angles B needs to be replaced, so that the included angle A between the two profiles is formed, which can realize the adjustment of the angle between the profile connecting curtain wall splicing device plates, and then adapt to curtain wall splicing devices with different angles. The profile has a plug-in structure, and the two horizontal parts of the connecting member are respectively plugged into the plug-in structures of the two profiles. Among them, the plug-in structure is two grooves formed on the profile, and the two horizontal parts of the connecting member are plugged into the grooves. During construction, one side of the two horizontal parts of the connecting member is respectively plugged into the two grooves of one profile, and the other side of the two horizontal parts of the connecting member is respectively plugged into the two grooves of the other profile. The unit plate can be adhered to the profile of the splicing device through a structural adhesive strip:

[0005] The prior art has the following disadvantages:

[0006] Firstly, the prior art adjusts the angle of the horizontal part by changing the angle of the bending plate, and then adjusts the angle of the adjacent two profiles. When changing the angle of the bending plate, the bending part of the bending plate will inevitably bend and stretch, which may cause the thickness of the bending part of the bending plate to be lower, or stress and cracks to occur, thus the strength of the bending plate cannot be guaranteed during subsequent use.

[0007] In addition, the plug-in mode needs to slide the profile along the wall surface transversely to separate the profile from the transverse part, and then remove the profile. However, because the unit blocks are adhered to the profile by the structural adhesive tape on the back surface, the unit blocks adhered to the surface will be moved when the profile is slid transversely, and the profile on the other side of the back surface of the unit block will be moved. Because the profile on the side is limited, the unit block and the profile adhered to the back surface will be hindered when they are slid transversely, that is, the plug-in mode will affect the subsequent disassembly of the profile.

Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0040] Please refer to Figures 1-12 The present application provides a technical solution:

[0041] A unit type curtain wall splicing device, comprising two symmetrical fixed seats 1 arranged on the wall surface, the fixed seat 1 is provided with a fixed hole 2 for expansion bolts to pass through, when installed on the wall surface, the expansion bolts pass through the fixed hole 2, so that the fixed seat 1 is fixed on the wall surface, both sides of the fixed seat 1 are provided with a plug 3 for inserting the profile, the fixed seat 1 is also provided with a storage mechanism for the plug 3 to expand, an extension mechanism for the plug 3 to extend, and an inclination mechanism for the plug 3 to swing, the fixed seat 1 is also provided with a main drive mechanism and a secondary drive mechanism for controlling the storage mechanism, the extension mechanism and the inclination mechanism, and a connecting mechanism is arranged between the two fixed seats 1.

[0042] The actual effect of the storage mechanism in the present application is to drive the plug 3 to rotate by 90 degrees into the fixed seat 1, so that the plug 3 actively separates from the profile without changing the position of the profile, which is convenient for directly removing the profile, the actual effect of the extension mechanism is that when the profile is removed subsequently, the plug 3 inserted into the profile is moved and stored into the fixed seat 1 by the extension mechanism, and then the plug 3 rotates by 90 degrees, and the new profile is placed on the side of the fixed seat 1, the plug 3 rotates by 90 degrees to face the groove of the profile, and then the plug 3 is controlled to extend into the profile by the extension mechanism, the actual effect of the inclination mechanism is that after the plug 3 is inserted into the profile, the angle of the plug 3 is adjusted by rotating, and then the angle of the profile connected with the plug 3 is adjusted, that is, the included angle between the two adjacent profiles can be adjusted during installation, and then the included angle between the two adjacent unit plates can be adjusted, the actual effect of the main drive mechanism is to control the two storage mechanisms or the extension mechanisms or the inclination mechanisms of the same fixed seat 1 to operate simultaneously, and the secondary drive mechanism can be used to control the single storage mechanism or the extension mechanism or the inclination mechanism in the single fixed seat 1 to operate, or can be used to control the storage mechanism or the extension mechanism or the inclination mechanism on the same side of the two fixed seats 1 to operate.

[0043] Embodiment one: the storage mechanism includes two rotating shafts 11 which are symmetrically arranged and rotatably connected in the fixed seat 1, one end of the rotating shaft 11 is fixedly connected with a lower worm gear 28, the storage mechanism further includes a lower worm 27 which is rotatably connected in the fixed seat 1 and is in meshing connection with the lower worm gear 28, the rotating shaft 11 is further rotatably connected with a swing arm 5, the swing arm 5 is sleeved with an inner plug frame 4, one end of the inner plug frame 4 is used for fixing a plug 3, one end of the lower worm 27 extends outward and is fixedly connected with a lower bevel gear ring 31 and a transmission bevel gear 32 respectively;

[0044] In actual operation, referring to Figure 4 , at this time, the plug 3 is extended out of the fixed seat 1 and is in a profile insertion state (the profile is not drawn), therefore, when it is needed to directly pull out the profile, by applying force to the transmission bevel gear 32 in the present solution to drive the lower bevel gear ring 31 to idle and the lower worm 27 to rotate, the lower worm gear 28 in meshing connection can drive the rotating shaft 11 to rotate, and then the swing arm 5 and the inner plug frame 4 can drive the plug 3 in the retracted state to rotate ninety degrees into the fixed seat 1, and the plug 3 retracted in the fixed seat 1 can be retracted into the fixed seat 1 by reversing the rotation of the swing arm 5 and the inner plug frame 4 by ninety degrees along with the rotating shaft 11. Figure 4

[0045] Embodiment two: the extension mechanism includes an inner threaded tube 36 fixed on one side of the plug 3 and located in the inner plug frame 4, one end of the inner threaded tube 36 extends to penetrate and slide connect with the middle position of the end surface of the swing arm 5, the swing arm 5 is rotatably connected with a threaded rod 37 which is threadedly connected with the inner threaded tube 36 at the center of the end away from the inner plug frame 4, one end of the threaded rod 37 is fixedly connected with an upper bevel gear 38 which is arranged on the same side of the lower bevel gear ring 31;

[0046] In actual operation: in actual use, referring to Figure 4 and Figure 5 , by applying force to the upper bevel gear 38 to drive the threaded rod 37 to rotate, the inner threaded tube 36 can drive the inner plug frame 4 to move along with the rotation of the threaded rod 37 by the threaded connection between the threaded rod 37 and the inner threaded tube 36, and the plug 3 can move relative to the swing arm 5; it is additionally stated that the inner plug frame 4 in the present solution is arranged in a U shape, and the swing arm 5 is arranged in a rectangular column shape, therefore, the inner plug frame 4 can only slide along the surface of the swing arm 5, and the inner threaded tube 36 fixed with the inner plug frame 4 and the plug 3 cannot rotate but only slide.

[0047] ​Example 3: The tilting mechanism includes an upper worm gear 29 fixed to the side of the swing arm 5 and rotatably connected to the axial surface of the rotating shaft 11, and an upper worm 30 rotatably connected to the axial surface of the rotating shaft 11 and meshing with the upper worm gear 29. One end of the upper worm 30 extends outward and is fixedly connected to a middle spur gear 33 and a transmission bevel gear 32. The tooth surface of the middle spur gear 33 meshes with a meshing spur gear 34 rotatably connected to the axial surface of the rotating shaft 11, and the end face of the meshing spur gear 34 is fixedly connected to a middle bevel gear 35.

[0048] In actual operation: such as Figure 4 and Figure 5 As shown, by applying a force to the transmission bevel gear 32 on the upper worm 30, causing the middle spur gear 33 to rotate and the upper worm 30 to rotate, the meshing connection of the upper worm wheel 29 can be achieved, which in turn drives the fixedly connected swing arm 5 to rotate and swing. This allows the inner insert frame 4 to drive the plug 3 to adjust its angle. When the middle spur gear 33 rotates, it will drive the meshing spur gear 34 to rotate, thereby allowing the middle bevel gear 35, whose end face is fixed, to idle. In addition, the opening side of the inner insert frame 4 is located on the side of the swing arm 5 where the upper worm wheel 29 is installed, and there is a sufficient gap between the swing arm 5 and the edge of the end face of the upper worm wheel 29 for the inner insert frame 4 to pass through. Therefore, it can be ensured that the inner insert frame 4 moves along the swing arm 5 until the plug 3 fits against the end of the swing arm 5.

[0049] Example 4: The main drive mechanism includes an input mechanism and a transmission mechanism. The transmission mechanism includes a screw 18 rotatably mounted in the fixed seat 1 and arranged parallel to the rotating shaft 11. Two rotating shafts 11 are symmetrically arranged about the screw 18, and a lifting seat 19 is threadedly connected to the screw 18 and sleeved in the fixed seat 1. By sleeved between the lifting seat 19 and the inside of the fixed seat 1, the lifting seat 19 can only slide and cannot rotate. The sides of the lifting seat 19 are respectively rotatably connected to an upper bevel gear ring 23 for meshing with the upper bevel gear 38, a middle bevel gear ring 22 for meshing with the transmission bevel gear 32 at the upper worm 30, and a bottom bevel gear ring 21 for meshing with the transmission bevel gear 32 on the lower worm 27. The inner arc surfaces of the upper bevel gear ring 23, the middle bevel gear ring 22, and the bottom bevel gear ring 21 are all provided with straight tooth surfaces 25.

[0050] Therefore, in actual operation: by rotating the screw rod 18, the lifting seat 19 connected with the screw rod 18 is lifted to the upper side of the upper bevel gear ring 23, the middle bevel gear ring 22 and the bottom bevel gear ring 21, and the upper bevel gear 38, the transmission bevel gear 32 and the lower worm 27 are engaged, and the straight tooth surface 25 connected by engagement drives the upper bevel gear ring 23 to rotate, that is, the two upper bevel gears 38 connected with the upper bevel gear ring 23 rotate, that is, the two upper bevel gears 38 in the fixed seat 1 rotate at the same time, and drive the corresponding threaded rod 37 to rotate; or the straight tooth surface 25 at the middle layer position drives the middle bevel gear ring 22 to rotate, that is, the transmission bevel gear 32 on the end surface of the two upper worm gears 30 in the fixed seat 1 rotates at the same time, that is, the two swing arms 5 in the fixed seat 1 rotate at the same time; or the lower straight tooth surface 25 drives the bottom bevel gear ring 21 to rotate, that is, the transmission bevel gear 32 connected with the bottom bevel gear ring 21 and located in the fixed seat 1 rotates, that is, the two rotating shafts 11 in the fixed seat 1 rotate at the same time, that is, the two plugs 3 on the fixed seat 1 are simultaneously received into the fixed seat 1 or extended out of the fixed seat 1.

[0051] Further: the input mechanism includes a lifting rotating rod 20 arranged in the fixed seat 1 and penetrating through the upper bevel gear ring 23, the middle bevel gear ring 22 and the bottom bevel gear ring 21, and the lifting rotating rod 20 is fixedly connected with three input straight gears 26, and the input straight gears 26 are alternately used to engage with the straight tooth surface 25 on the upper bevel gear ring 23, the middle bevel gear ring 22 and the bottom bevel gear ring 21, as shown in Figure 4 and Figure 5 By pressing the lifting rotating rod 20 downward, the three input straight gears 26 on the surface of the lifting rotating rod 20 can engage with the straight tooth surface 25 on the upper bevel gear ring 23, the middle bevel gear ring 22 and the bottom bevel gear ring 21, respectively, one end of the lifting rotating rod 20 is fixedly connected with a bottom spring rod 49 rotatably connected with the inner wall of one side of the fixed seat 1, and the bottom spring rod 49 can be elastically contracted during the pressing process of the lifting rotating rod 20, and after the lifting rotating rod 20 is released, the elastic elongation of the bottom spring rod 49 can realize the upward reset of the lifting rotating rod 20, and the other end penetrates the end surface of the same side of the screw rod 18 and extends outwardly through the fixed seat 1, and the other inner wall of the fixed seat 1 is fixedly connected with a guide sleeve 24 sleeved on the lifting rotating rod 20, as shown in Figure 1 The end surface of the penetrating end of the lifting rotating rod 20 and the screw rod 18 is provided with a groove for the insertion of a letter opener, so that the rotation of the lifting rotating rod 20 or the screw rod 18 can be realized by inserting and rotating the letter opener:

[0052] Therefore, in actual use: as shown in Figure 4 and Figure 5As shown, the three layers of input straight gears 26 in the initial state are not equal in distance to the corresponding mating straight tooth surfaces 25, so the input straight gear 26 of the upper layer of the lifting rotating rod 20 meshes with the straight tooth surface 25 on the inner side of the upper bevel gear ring 23, while the input straight gears 26 of the other two layers are misaligned with the corresponding straight tooth surfaces 25 and are located above the corresponding straight tooth surfaces 25, so when the bottom spring rod 49 rotates relative to the fixed seat 1, the input straight gear 26 of the upper layer rotates to drive the meshing connected straight tooth surface 25 and the upper bevel gear ring 23 at the position thereof; press the lifting rotating rod 20 downward to the middle layer of the input straight gear 26 meshes with the straight tooth surface 25 on the inner side of the transmission bevel gear 32 at the upper worm 30, while the input straight gears 26 of the upper and lower layers are located below and above the corresponding straight tooth surfaces 25, at this time, when the lifting rotating rod 20 rotates, the input straight gear 26 at the middle layer drives the meshing straight tooth surface 25 and the middle bevel gear ring 22 at the position thereof to rotate, while the input straight gears 26 of the upper and lower layers are idling; continue to press the lifting rotating rod 20 to the upper and middle layers of the input straight gears 26 are located below the corresponding straight tooth surfaces 25, while the input straight gear 26 of the lower layer meshes with the corresponding straight tooth surface 25, that is, the rotation of the lifting rotating rod 20 can realize the idling of the input straight gears 26 of the upper and middle layers while the input straight gear 26 of the lower layer drives the straight tooth surface 25 meshing therewith and the bottom bevel gear ring 21 at the position thereof to rotate, that is, it is convenient to realize the simultaneous operation of the two extension mechanisms or two tilting mechanisms or two storage mechanisms in the fixed seat 1, which is convenient for use during initial assembly.

One of the fixed seats 1 is further fixedly connected with two shift plates 12, and the two shift plates 12 are provided with a rotating handle 13 inserted therebetween. One end of the rotating handle 13 is fixedly connected with an end bevel gear 47 for meshing connection with the input bevel gear ring 16.

When the resisting rod 45 is forced to move, the relative spring telescopic rods 43 and the extension arm 7 or the connecting column 6 are driven to move.

Specifically, by rotating the lead screw 8 outside the fixing base 1, the rhombus block 9 is lowered and sequentially passes through a plurality of two convex shafts 39 distributed side by side under the condition of threaded connection and insertion with the outer wall of the fixing base 1. When the rhombus block 9 passes between the two convex shafts 39, the two convex shafts 39 are in contact with the two side inclined surfaces of the rhombus block 9 respectively, and as the rhombus block 9 continues to move downward, that is, the farthest point of the rhombus block 9 gradually approaches the convex shaft 39, the two convex shafts 39 will move away continuously, thereby driving the bearing 10 connected thereto to move, that is, the two bearings 10 drive the extension arm 7 and the connecting column 6 connected thereto to move, thereby simultaneously driving the two spring telescopic rods 43 at the corresponding positions of the two fixing bases 1 to move against the tension of the internal spring rod 46, that is, the spring telescopic rods 43 on the same side of the upper layer, the middle layer or the lower layer of the two fixing bases 1 are simultaneously moved. When the upper bevel gear block 42 on the same side of the two fixing bases 1 is engaged with the upper bevel gear 38, the position of the rotating handle 13 is adjusted, so that the rotating handle 13 drives the upper layer input bevel gear ring 16 to rotate, thereby driving the upper layer connecting column 6 to rotate, that is, the upper bevel gear block 42 on the same side of the two fixing bases 1 is rotated, thereby driving the plug 3 on the same side of the two fixing bases 1 to move out of the groove on the profile; when the middle bevel gear block 41 on the same side of the two fixing bases 1 is engaged with the middle bevel gear 35 at the middle part of the upper worm 30, the position of the rotating handle 13 is adjusted, so that the rotating handle 13 drives the middle layer input bevel gear ring 16 to rotate, thereby driving the middle layer connecting column 6 to rotate, that is, the middle bevel gear 35 on the same side of the two fixing bases 1 is rotated, thereby driving the plug 3 on the same side of the two fixing bases 1 to swing simultaneously, so as to adjust the angle between the profile and the fixing base 1 during actual use, that is, to adjust the angle between the adjacent two unit plate blocks fixed on the profile; when the lower bevel gear block 40 on the same side of the two fixing bases 1 is engaged with the lower bevel gear ring 31, the position of the rotating handle 13 is adjusted, so that the rotating handle 13 drives the lower layer input bevel gear ring 16 to rotate, thereby driving the lower layer connecting column 6 to rotate, that is, the lower bevel gear block 40 on the same side of the two fixing bases 1 is rotated, thereby driving the plug 3 on the same side of the two fixing bases 1 to rotate in and out of the fixing base 1 simultaneously;
