DETAILED DESCRIPTION

The technical solution of the present invention will be described clearly and completely below in conjunction with Figures 1 to 10. 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.

The present invention provides a lightweight assembled steel structure wall through improvement, as shown in Figures 1 to 10, including an installation frame 1 and a splicing wall panel 2, a plurality of groups of vertical plates 101 are arranged at intervals on the installation frame 1, and the splicing wall panel 2 is installed between adjacent vertical plates 101; a vertical linkage hole 203 is opened inside the splicing wall panel 2, and an upper meshing cavity 205 and a lower meshing cavity 207 are also opened inside the splicing wall panel 2, which are coaxially arranged with the linkage hole 203, a sliding cavity 1 206 connected to the upper meshing cavity 205 is opened on both sides of the upper meshing cavity 205, and a sliding cavity 208 connected to the lower meshing cavity 207 is opened on both sides of the lower meshing cavity 207; a ball screw 211 is arranged in the linkage hole 203, and a ball screw 212 is installed in the upper meshing cavity 205. A linkage gear 213 is threadably matched with the ball screw 211, and a linkage ring 218 is rotatably arranged in the lower meshing cavity 207 and is matched with the thread of the ball screw 211; an upper locking bar 214 meshing with the linkage gear 213 is slidably arranged in the sliding cavity 1 206, and a sliding arm 221 and a lower locking bar 223 are slidably arranged in the sliding cavity 208, a magnetic attraction portion 1 222 is arranged on the side of the sliding arm 221 close to the lower locking bar 223, and a magnetic attraction portion 226 is arranged on the side of the lower locking bar 223 close to the sliding arm 221; when the ball screw 211 is squeezed and moves downward along the linkage hole 203, the upper locking bar 214 and the lower locking bar 223 pop out to both sides and lock the vertical plate 101.

In this embodiment: the lightweight assembled steel structure wall is mainly divided into two parts: the installation frame 1 and the splicing wall panel 2. When the device is in use, first adjust the position and angle of the base 113 according to actual needs and fix the installation frame 1, and then install multiple groups of splicing wall panels 2. During installation, the T-rails 201 on both sides of the splicing wall panel 2 slide downward along the T-slots 102 on the vertical plate 101, and then install the upper splicing wall panel 2. When the extrusion column 212 is squeezed, the ball screw 211 is squeezed and moves downward along the linkage hole 203. Under the clockwise drive of the linkage gear 213, the upper locking strips 214 on both sides will move outward along the sliding cavity 1 206 and insert into the upper locking groove 103. And under the clockwise swing of the linkage ring 218 and the drive of the linkage rod 220, the sliding arm 221 will slide outward. Since the magnetic attraction part 1 222 and the magnetic attraction part 2 226 have the same magnetic properties, the repulsive force between the magnetic attraction part 1 222 and the magnetic attraction part 2 226 is greater than the elastic force of the first return spring 225, so the lower locking strip 223 will move outward along the sliding cavity 208 and insert into the lower locking groove 104. When all the splicing wall panels 2 are installed, the splicing wall panels 2 on the top layer have not yet locked the vertical panels 101 on both sides. At this time, the top beam 107 is installed to the top of the installation frame 1, and the top beam 107 will squeeze the extrusion column 212 of the top layer of splicing wall panels 2 and complete the locking. At this time, the limit block 108 will be inserted into the positioning cavity 105, and the telescopic block 110 will automatically pop up to lock the through hole 106.

When the wall needs to be dismantled, first press the telescopic block 110 inward, and then pull out the top beam 107 upward. When the top beam 107 or the upper splicing wallboard 2 is dismantled, the ball screw 211 returns to its original state under the action of the second return spring 227. Since the linkage gear 213 and the linkage ring 218 are both threadedly connected to the ball screw 211, the upper locking strips 214 on both sides will move inward along the sliding cavity 1 206 and disengage from the upper locking groove 103 under the counterclockwise drive of the linkage gear 213. And under the counterclockwise rotation of the linkage ring 218 and the drive of the linkage rod 220, the sliding arm 221 will slide inward. Since the magnetic attraction part 1 222 and the magnetic attraction part 2 226 have the same magnetic properties, the repulsive force between the magnetic attraction part 1 222 and the magnetic attraction part 2 226 is smaller than the elastic force of the first return spring 225 , so the lower locking bar 223 moves inward along the sliding cavity 208 and disengages from the lower locking groove 104 .

5 and 7 , an extrusion column 212 is disposed on the top of the ball screw 211 , and a telescopic cavity 204 cooperating therewith is disposed on the top of the linkage hole 203 .

In this embodiment, a telescopic chamber 204 is designed to accommodate the extrusion column 212 after it is squeezed.

Referring to Figures 5 and 7-8, a symmetrical swing seat 219 is provided on the outer wall of the linkage ring 218, a linkage rod 220 is installed on the swing seat 219, and the other end of the linkage rod 220 is movably connected to the sliding arm 221; reset grooves 209 are opened on the inner walls of both sides of the sliding cavity 208, and convex plates 224 are provided on the outer walls of both sides of the lower locking strip 223, and multiple groups of first reset springs 225 are provided on the inner side of the convex plate 224, and the convex plate 224 is connected to the inner wall through the first reset spring 225 and the reset groove 209.

In this embodiment: when the extrusion column 212 is squeezed, the ball screw 211 is squeezed and moves downward along the linkage hole 203. Under the clockwise drive of the linkage gear 213, the upper locking strips 214 on both sides will move outward along the sliding cavity 1 206 and insert into the upper locking groove 103. And under the drive of the linkage ring 218 and the linkage rod 220, the sliding arm 221 will slide outward. Since the magnetic attraction part 1 222 and the magnetic attraction part 2 226 have the same magnetic properties, the repulsive force between the magnetic attraction part 1 222 and the magnetic attraction part 2 226 is greater than the elastic force of the first return spring 225, so the lower locking strip 223 will move outward along the sliding cavity 2 208 and insert into the lower locking groove 104.

7-8 , the magnetic attraction portion 1 222 and the magnetic attraction portion 226 have the same magnetic properties.

In this embodiment, in order to control the locking and unlocking of the lower locking bar 223 by adjusting the magnitude of the repulsive force between the sliding arm 221 and the lower locking bar 223 , the magnetic properties of the first magnetic attraction portion 222 and the second magnetic attraction portion 226 are made the same.

5 and 7 , the upper locking strip 214 is provided with a meshing portion 215 that cooperates with the linkage gear 213 , the upper and lower inner walls of the sliding cavity 1 206 are provided with symmetrical sliding grooves 217 , and the upper and lower outer walls of the upper locking strip 214 are provided with protrusions 216 that cooperate with it.

In this embodiment, in order to further improve the stability of the upper locking strip 214 when sliding, a sliding groove 217 and a protrusion 216 structure are designed.

5 to 8 , a second return spring 227 is disposed at the bottom of the ball screw 211 , and the ball screw 211 is connected to the bottom of the linkage hole 203 via the second return spring 227 .

In this embodiment, when the splicing wallboard 2 is disassembled, in order to automatically reset the ball screw 211 and further unlock the vertical board 101, the ball screw 211 is connected to the bottom of the linkage hole 203 through the second reset spring 227. When the top beam 107 or the splicing wallboard 2 on the upper layer is removed, the ball screw 211 is restored to its original state under the action of the second reset spring 227. Since the linkage gear 213 and the linkage ring 218 are both threadedly connected to the ball screw 211, the upper locking strips 214 on both sides will move inward along the sliding cavity 1 206 and disengage from the upper locking groove 103 under the counterclockwise drive of the linkage gear 213. And under the counterclockwise rotation of the linkage ring 218 and the drive of the linkage rod 220, the sliding arm 221 will slide inward. Since the magnetic attraction part 1 222 and the magnetic attraction part 2 226 have the same magnetic properties, the repulsive force between the magnetic attraction part 1 222 and the magnetic attraction part 2 226 is smaller than the elastic force of the first return spring 225 , so the lower locking bar 223 moves inward along the sliding cavity 208 and disengages from the lower locking groove 104 .

1-2 and 4 , a T-slot 102 is provided on the opposite side between the vertical plates 101 , T-rails 201 are provided on both sides of the spliced wallboard 2 , and panels 202 are provided on the front and rear sides of the spliced wallboard 2 .

In this embodiment, in order to quickly install and position the splicing wallboard 2, a T-slot 102 and a T-rail 201 structure are designed. In order to make the splicing wallboard 2 shield the vertical board 101, and to improve the aesthetics while preventing rainwater from falling into the upper locking groove 103 and the lower locking groove 104 to cause corrosion, a panel 202 structure is designed, and the panels 202 on both sides can completely shield the vertical board 101 in the middle.

2 and 9 , the inner wall of the vertical plate 101 is provided with multiple sets of upper locking grooves 103 cooperating with the upper locking strip 214 and lower locking grooves 104 cooperating with the lower locking strip 223 ; the bottom of the mounting frame 1 is provided with multiple sets of rotating seats 112 , and the rotating seats 112 are provided with bases 113 .

In this embodiment, in order to improve the strength of the wall, the position and angle of the base 113 can be freely adjusted as needed, so a rotating base 112 is designed. For example, when the bases 113 on both sides are arranged perpendicular to the splicing wallboard 2, the two sets of bases 113 inside are arranged parallel to the splicing wallboard 2, the earthquake resistance and wind resistance of the wall can be improved.

Referring to Figures 2-3 and 10, a positioning cavity 105 is provided at the top of the outermost vertical plate 101, and a through hole 106 facing outward is provided on the inner wall of the positioning cavity 105; a top beam 107 is installed on the top of the mounting frame 1, and a limit block 108 cooperating with the positioning cavity 105 is provided at the bottom of the top beam 107, an extrusion cavity 109 is provided on the outer side of the limit block 108, and a telescopic block 110 cooperating with the through hole 106 is movably provided in the extrusion cavity 109, and the telescopic block 110 is connected to the inner wall of the extrusion cavity 109 through a positioning spring 111.

In this embodiment: after all the splicing wall panels 2 are installed, the splicing wall panels 2 at the top layer have not yet locked the vertical panels 101 on both sides. At this time, the top beam 107 is installed on the top of the installation frame 1, and the top beam 107 will squeeze the extrusion column 212 of the top splicing wall panel 2 and complete the locking. At this time, the limit block 108 will be inserted into the positioning cavity 105, and the telescopic block 110 will automatically pop out to lock the through hole 106. When the top beam 107 needs to be removed, first press the telescopic block 110 inward, and then pull the top beam 107 upward.

5 and 7 , the linkage ring 218 is provided with annular grooves 228 on its upper and lower sides, and the lower engaging cavity 207 is provided with matching annular rails 229 on its upper and lower inner walls; and the spliced wall panel 2 is provided with a plurality of cavities 210 inside.

In this embodiment, in order to install the linkage ring 218 and ensure that it swings back and forth relative to the lower engagement cavity 207, a ring groove 228 and a ring rail 229 structure that cooperate with each other are designed. In order to further improve the noise reduction capability and thermal insulation effect of the spliced wallboard 2, a cavity 210 structure is designed.

Working principle of the present invention: When the device is used, first adjust the position and angle of the base 113 according to actual needs and fix the installation frame 1, and then install multiple groups of spliced wall panels 2. During installation, slide the T-shaped rails 201 on both sides of the spliced wall panels 2 downward along the T-shaped slots 102 on the vertical plate 101, and then install the upper spliced wall panels 2. When the extrusion column 212 is squeezed, the ball screw 211 is squeezed and moves downward along the linkage hole 203. Under the clockwise drive of the linkage gear 213, the upper locking strips 214 on both sides will move outward along the sliding cavity 1 206 and insert into the upper locking slot 103. And under the clockwise swing of the linkage ring 218 and the drive of the linkage rod 220, the sliding arm 221 will slide outward. Since the magnetic attraction part 1 222 and the magnetic attraction part 2 226 have the same magnetic properties, the repulsive force between the magnetic attraction part 1 222 and the magnetic attraction part 2 226 is greater than the elastic force of the first return spring 225, so the lower locking strip 223 will move outward along the sliding cavity 208 and insert into the lower locking groove 104. When all the splicing wall panels 2 are installed, the splicing wall panels 2 on the top layer have not yet locked the vertical panels 101 on both sides. At this time, the top beam 107 is installed to the top of the installation frame 1, and the top beam 107 will squeeze the extrusion column 212 of the top layer of splicing wall panels 2 and complete the locking. At this time, the limit block 108 will be inserted into the positioning cavity 105, and the telescopic block 110 will automatically pop up to lock the through hole 106.

When the wall needs to be dismantled, first press the telescopic block 110 inward, and then pull out the top beam 107 upward. When the top beam 107 or the upper splicing wallboard 2 is dismantled, the ball screw 211 returns to its original state under the action of the second return spring 227. Since the linkage gear 213 and the linkage ring 218 are both threadedly connected to the ball screw 211, the upper locking strips 214 on both sides will move inward along the sliding cavity 1 206 and disengage from the upper locking groove 103 under the counterclockwise drive of the linkage gear 213. And under the counterclockwise rotation of the linkage ring 218 and the drive of the linkage rod 220, the sliding arm 221 will slide inward. Since the magnetic attraction part 1 222 and the magnetic attraction part 2 226 have the same magnetic properties, the repulsive force between the magnetic attraction part 1 222 and the magnetic attraction part 2 226 is smaller than the elastic force of the first return spring 225 , so the lower locking bar 223 moves inward along the sliding cavity 208 and disengages from the lower locking groove 104 .

The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
