Description
Technical Field
[0001] This utility model relates to the field of curtain wall structure technology, and in particular to an adjustable connection and fixing device for curtain wall keel and embedded parts. Background Technology
[0002] The connection and fixing of the curtain wall keel to the embedded parts is the core link in the installation of the curtain wall system. Its connection strength, positional accuracy, and adjustment flexibility directly determine the overall stability, safety, and appearance quality of the curtain wall. As the load-bearing carrier between the curtain wall and the main building structure, the embedded parts need to form a reliable connection with the keel to withstand various loads such as the curtain wall's self-weight, wind load, and seismic action. At the same time, they need to adapt to the positional adjustment needs caused by building errors (such as embedded part pre-embedding deviation and concrete structure dimensional errors) during construction.
[0003] However, the positioning requirements for curtain wall connection embedded parts are very high. Once the existing curtain wall connection embedded parts are installed, their positions cannot be adjusted. Accurate calculation and positioning are required during the design and installation process. However, due to many uncertainties in construction, the embedded position of the curtain wall connection embedded parts may deviate, resulting in significant defects between the curtain wall components and affecting the overall appearance.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0020] Example 1 Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides an adjustable connection and fixing device for curtain wall keel and embedded parts, including an installation mechanism 1, a height adjustment component 2 at the bottom of the installation mechanism 1, and a movable adjustment component 3 on the height adjustment component 2. The mounting mechanism 1 includes a bracket 101 connected to the height adjustment component 2. A fixing frame 102 is provided on the outer surface of the bracket 101. A mounting block 104 is movably arranged inside the fixing frame 102. A movable groove is opened inside the mounting block 104. A movable rod 105 is inserted into the movable groove. A locking block 1051 is fixedly connected to one end of the movable rod 105. A moving ring 106 is sleeved on the outer surface of the movable rod 105. A groove 107 is opened inside the mounting block 104. A connecting rod 108 is inserted into the groove 107. A stop block 110 is fixedly connected to one end of the connecting rod 108. A telescopic spring 109 is provided between the inner top wall of the groove 107 and the top of the stop block 110. The telescopic spring 109 is sleeved on the outer surface of the connecting rod 108.
[0021] Specifically, a guide strip is fixedly connected to the top of the bracket 101, and a guide groove matching the guide strip is opened on the top of the mounting block 104. The guide strip is slidably connected to the guide groove. A fixing plate 111 is fixedly connected to one end of the guide strip, and a telescopic rod 112 is fixedly connected to one side of the fixing plate 111. The end of the telescopic rod 112 away from the fixing plate 111 is connected to the mounting block 104. A compression spring 113 is provided between the fixing plate 111 and the mounting block 104, and the compression spring 113 is sleeved on the outer surface of the telescopic rod 112. A mounting rod 114 is provided at the top center of the bracket 101. Four positioning holes 115 are arranged in a ring array on the outer surface of the mounting rod 114. One end of the locking block 1051 is inclined. One side of the bottom of the stop block 110 is inclined and the locking block 1051 is engaged with the stop block 110. The end of the locking block 1051 away from the stop block 110 is engaged with the positioning hole 115. The two sides of the moving ring 106 are inclined and the moving ring 106 cooperates with the stop block 110. The fixing frame 102 is connected to the bracket 101 by bolts 103.
[0022] Furthermore, by pushing the movable rod 105 forward, the movable rod 105 drives the locking block 1051 to move forward. During the movement, the locking block 1051 presses upward against the stop block 110, and the stop block 110 presses upward against the telescopic spring 109. When the locking block 1051 engages with the positioning hole 115, the end of the locking block 1051 away from the positioning hole 115 separates from the stop block 110. Using the elastic potential energy of the telescopic spring 109, the stop block 110 is pushed downward, so that the stop block 110 abuts against the locking block 1051, thereby limiting and fixing the installation rod 114 and preventing loosening at the connection between the curtain wall keel and the embedded parts.
[0023] Example 2 Reference Figure 1 , Figure 3 and Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0024] The height adjustment assembly 2 includes an adjustment box 201 rotatably connected to the bottom of the bracket 101. A worm gear 202 is inserted inside the adjustment box 201, and a worm wheel 203 is movably arranged inside the adjustment box 201, with the worm wheel 203 cooperating with the worm gear 202. An adjustment cylinder 204 is fixedly connected to the bottom of the adjustment box 201. A threaded rod 205 is fixedly connected to the outer surface of the worm wheel 203. A telescopic sleeve 206 is threadedly connected to the outer surface of the threaded rod 205. A turntable 207 is fixedly connected to one end of the worm gear 202. A sliding groove is formed on the inner wall of the adjustment cylinder 204. A slider is fixedly connected to the outer surface of the telescopic sleeve 206. The telescopic sleeve 206 is slidably connected to the adjustment cylinder 204 through the slider and the sliding groove.
[0025] Specifically, the movable adjustment component 3 includes an adjustment frame 301 located below the height adjustment component 2. The top of the adjustment frame 301 has an adjustment groove 302. An adjustment screw 303 is inserted into the adjustment groove 302, and one end of the adjustment screw 303 is fixedly connected to a rotating wheel 305. A threaded sleeve is threadedly connected to the outer surface of the adjustment screw 303. A movable block 304 is fixedly fitted onto the outer surface of the threaded sleeve. One end of the telescopic sleeve 206 passes through the adjustment groove 302 and is connected to the movable block 304. A limiting slider 306 is fixedly connected to the outer surface of the movable block 304. A limiting groove is formed on the inner wall of the adjustment groove 302. The movable block 304 is slidably connected to the adjustment groove 302 through the limiting slider 306 and the limiting groove.
[0026] Furthermore, through the height adjustment component 2, the rotating turntable 207 drives the worm gear 202 to rotate, which in turn drives the worm wheel 203 to rotate. The worm wheel 203 drives the threaded rod 205 to rotate, and the rotation of the threaded rod 205 drives the telescopic sleeve 206 to move up and down within the adjusting cylinder 204, thereby adjusting the distance between the bracket 1 and the adjusting box 201, allowing the bracket 1 to be adjusted in a lifting manner. By rotating the rotating wheel 305, the adjusting screw 303 is driven to rotate, thereby causing the moving block 304 to move within the adjusting groove 302. The moving block 304 drives the telescopic sleeve 206 to move, thereby adjusting the lateral fixed position of the bracket 1, increasing the practicality of the device.
[0027] Working Principle: In use, rotating the turntable 207 drives the worm gear 202 to rotate, which in turn drives the worm wheel 203 to rotate. The worm wheel 203 drives the threaded rod 205 to rotate, and the rotation of the threaded rod 205 causes the telescopic sleeve 206 to move up and down within the adjusting cylinder 204, thereby adjusting the distance between the bracket 1 and the adjusting box 201, allowing the bracket 1 to be adjusted vertically. Rotating the turntable 305 drives the adjusting screw 303 to rotate, thereby moving the moving block 304 within the adjusting groove 302. The moving block 304 drives the telescopic sleeve 206 to move, thereby adjusting the lateral fixed position of the bracket 1. The guide bar and the guide groove work together to pull the mounting block 104 outward, causing the movable rod 105 to move outward. At this time, the compression spring 113 is compressed, and then the mounting rod 114 is compressed. When the positioning hole 117 and the locking block 1051 are aligned, the mounting block 104 is released. By pushing the movable rod 105 forward, the movable rod 105 drives the locking block 1051 to move forward. During the movement, the locking block 1051 presses upward against the stop block 110, and the stop block 110 presses upward against the telescopic spring 109. Through the threaded groove on the inner wall of the front fork connecting tube 116, it is threadedly fixed to the threaded part at the top of the front fork riser tube 115. When the locking block 1051 is engaged with the positioning hole 117, the end of the locking block 1051 away from the positioning hole 117 is separated from the stop block 110. Using the elastic potential energy of the telescopic spring 109, the stop block 110 is pushed downward, so that the stop block 110 is engaged between the locking block 1051 and the moving ring 106, limiting and fixing the mounting rod 114 to prevent loosening at the connection between the curtain wall keel and the embedded parts.
