The terms "set", "open", "installed", "connected", and "connected" should be interpreted broadly.

[0041] See Figure 1 , Figure 2 , Figure 3 The present application provides a multi-purpose building lock, including a first body 10 and a second body 11. The first body 10 is provided with a first connecting plate 12 and a first bracket 13 at both ends, and the second body 11 is provided with a second connecting plate 14 and a second bracket 15 at both ends. The first connecting plate 12 and the second connecting plate 14 are rotatably connected by a first connecting structure 16 with a locking function.

[0042] This application provides a multi-purpose building lock that rotatably connects a first connecting plate 12 and a second connecting plate 14 via a first connecting structure 16. This allows the first connecting plate 12 and the second connecting plate 14 to rotate around the first connecting structure 16, thereby adjusting the angle between them. Since the first connecting structure 16 also has a locking function, after the angle between the first connecting plate 12 and the second connecting plate 14 is adjusted, the angle between them can be locked using the first connecting structure 16. Because the first connecting plate 12 is connected to the first body 10 and the second connecting plate 14 is connected to the second body 11, adjusting the angle between the first connecting plate 12 and the second connecting plate 14 can adjust the angle between the first body 10 and the second body 11. For example, see [link to example]. Figure 1 When the first body 10 and the second body 11 are in a parallel state, the lock forms a connecting lock, which acts on the connecting part; see also Figure 2 When the angle between the first body 10 and the second body 11 is 90°, the lock forms a corner lock, used to operate at corner locations; see also Figure 3 When the first body 10 from Figure 2 After rotating 180° in the state, to Figure 3 When in the correct state, the lock forms a corner lock, which is used to act on the corner.

[0043] The multi-purpose building lock provided in this application embodiment can be flexibly converted between a corner lock, an external corner lock, and a connecting lock. During construction, the angle between the first body 10 and the second body 11 can be adjusted according to different needs, thereby allowing one lock to be used on different fixed parts, greatly reducing the complexity of the construction process, lowering construction costs, and improving construction efficiency. By setting a first bracket 13 at one end of the first body 10 and a second bracket 15 at one end of the second body 11, the first bracket 13 and the second bracket 15 can be used as extension brackets for the lock during construction and connected to other structures of the fixed part.

[0044] See Figure 4 The first body 10 includes two parallel first horizontal plates 102 and a first side plate 103 fixed between the two first horizontal plates 102, wherein the two first horizontal plates 102 are located on the same side of the first side plate 103. The second body 11 includes two parallel second horizontal plates 113 and a second side plate 114 fixed between the two second horizontal plates 113, wherein the two second horizontal plates 113 are located on the same side of the second side plate 114. During construction, the first side plate 103 and the second side plate 114 are used to abut against the fixed part. The first side plate 103 is provided with a first U-shaped groove 104, and the second side plate 114 is provided with a second U-shaped groove 115; by providing the first U-shaped groove 104 and the second U-shaped groove 115, it is used to connect external assemblies during construction.

[0045] The number of first connecting plates 12 can be one. See, for example... Figures 1 to 4 There are two first connecting plates 12, which are arranged in parallel and respectively on the upper and lower sides of the first body 10. For example, the first connecting plates 12 are parallel to the first horizontal plates 102, and the two first connecting plates 12 are respectively connected to the two first horizontal plates 102.

[0046] The number of second connecting plates 14 can be one. See, for example... Figures 1 to 4 There are two second connecting plates 14, which are arranged in parallel and respectively on the upper and lower sides of the second body 11. For example, the second connecting plates 14 are parallel to the second horizontal plates 113, and the two second connecting plates 14 are respectively connected to the two second horizontal plates 113.

[0047] When there are two first connecting plates 12 and two second connecting plates 14, the two first connecting plates 12 and the two second connecting plates 14 correspond one-to-one, and the corresponding first connecting plates 12 and second connecting plates 14 are rotatably connected through the first connecting structure 16.

[0048] See Figure 4The first connecting structure 16 includes a first connecting bolt 161 passing through the first connecting plate 12 and the second connecting plate 14, and a first connecting nut 162 threadedly connected to the end of the first connecting bolt 161. Specifically, the first connecting plate 12 is provided with a first fixing hole 122 for the first connecting bolt 161 to pass through, and the second connecting plate 14 is provided with a second fixing hole 141 for the first connecting bolt 161 to pass through. When there are two first connecting structures 16, the first connecting bolts 161 in the two first connecting structures 16 are coaxially arranged.

[0049] During operation, the first connecting plate 12 and the second connecting plate 14 are overlapped, and the first fixing hole 122 and the second fixing hole 141 are aligned. The first connecting bolt 161 is passed through the first fixing hole 122 and the second fixing hole 141, and then the first connecting nut 162 is threaded onto the end of the first connecting bolt 161. When it is necessary to adjust the included angle between the first connecting plate 12 and the second connecting plate 14, the first connecting bolt 161 is loosened first, and then the first connecting plate 12 and / or the second connecting plate 14 is rotated around the first connecting bolt 161. After adjustment, the first connecting bolt 161 is tightened, and the first connecting plate 12 and the second connecting plate 14 are fixed together by the first connecting bolt 161 and the first connecting nut 162 to lock the included angle between them. To prevent the first connecting nut 162 from being lost during operation, the first connecting nut 162 is welded to the first connecting plate 12 or the second connecting plate 14.

[0050] The first connecting plate 12 and the first body 10 can be connected by welding or by fasteners such as bolts, without any specific limitation.

[0051] See Figures 1 to 4 The first connecting plate 12 is movable along the length direction of the first body 10, and a first locking structure 17 is provided between the first connecting plate 12 and the first body 10. By providing the first connecting plate 12 on the first body 10, the first connecting plate 12 can form an extension of the first body 10. By providing the first connecting plate 12 to move along the length direction of the first body 10 and using the first locking structure 17 to lock the first connecting plate 12 on the first body 10, the length of the extension of the first body 10 can be flexibly adjusted, thereby improving the applicability of the entire lock.

[0052] See Figure 4The first locking structure 17 includes a first locking bolt 171 passing through the first connecting plate 12, and a first locking nut 172 threadedly connected to the end of the first locking bolt 171; the first locking nut 172 is slidably mounted on the first body 10 along its length. Specifically, the first connecting plate 12 is provided with a first bolt hole for the first locking bolt 171 to pass through, and the first horizontal plate 102 of the first body 10 is provided with a first sliding groove 105 extending along its length; the first locking nut 172 is installed in the first sliding groove 105 and can slide along the first sliding groove 105.

[0053] During operation, the first connecting plate 12 is placed on the first horizontal plate 102, and the first bolt hole on the first connecting plate 12 is aligned with the first locking nut 172. The first locking bolt 171 is passed through the first bolt hole and threadedly connected to the first locking nut 172. When the position of the first connecting plate 12 needs to be adjusted, the first locking bolt 171 is loosened first, and then the first connecting plate 12 is moved. After the adjustment is completed, the first locking bolt 171 is tightened to fix the first connecting plate 12 on the first horizontal plate 102.

[0054] To further improve the length adjustment range of the first connecting plate 12 as an extension of the first body 10, see [reference needed]. Figure 4 The first connecting plate 12 is provided with a first elongated hole 121, and the first locking bolt 171 is used to pass through the first elongated hole 121 and can move within the first elongated hole 121.

[0055] The second connecting plate 14 and the second body 11 can be connected by welding or by fasteners such as bolts; no specific limitation is made here.

[0056] See Figures 1 to 4 The second connecting plate 14 is movable along the length of the second body 11, and a second locking structure 18 is provided between the second connecting plate 14 and the second body 11. By providing the second connecting plate 14 on the second body 11, the second connecting plate 14 forms an extension of the second body 11. By providing the second connecting plate 14 to move along the length of the second body 11 and using the second locking structure 18 to lock the second connecting plate 14 onto the second body 11, the length of the extension of the second body 11 can be flexibly adjusted, further improving the applicability of the entire lock.

[0057] See Figure 4The second locking structure 18 includes a second locking bolt 181 passing through the second connecting plate 14, and a second locking nut 182 threadedly connected to the end of the second locking bolt 181; the second locking nut 182 is slidably mounted on the second body 11 along its length. Specifically, the second connecting plate 14 is provided with a second bolt hole 142 for the second locking bolt 181 to pass through, and the second horizontal plate 113 of the second body 11 is provided with a second sliding groove 116 extending along its length; the second locking nut 182 is mounted in the second sliding groove 116 and can slide along the second sliding groove 116.

[0058] During operation, place the second connecting plate 14 on the second horizontal plate 113, align the second bolt hole 142 on the second connecting plate 14 with the second locking nut 182, and pass the second locking bolt 181 through the second bolt hole 142 and thread it into the second locking nut 182. When it is necessary to adjust the position of the second connecting plate 14, first loosen the second locking bolt 181, then control the movement of the second connecting plate 14. After the adjustment is completed, tighten the second locking bolt 181 to fix the second connecting plate 14 on the second horizontal plate 113.

[0059] The first bracket 13 and the first body 10 can be connected by welding or bolts, and the second bracket 15 and the second body 11 can also be connected by welding or bolts. No specific limitation is made here.

[0060] See Figure 4 The first bracket 13 is provided with a first groove 131, and one end of the first body 10 is disposed in the first groove 131. The first body 10 and the first bracket 13 are connected by a first quick-release structure 19. The second bracket 15 is provided with a second groove 151, and one end of the second body 11 is disposed in the second groove 151. The second body 11 and the second bracket 15 are connected by a second quick-release structure 20.

[0061] Specifically, the shape and size of the first groove 131 are adapted to the shape and size of the end of the first body 10. The shape and size of the second groove 151 are adapted to the shape and size of the end of the second body 11. In operation, one end of the first body 10 is inserted into the first groove 131, and then the first body 10 is quickly connected to the first bracket 13 through the first quick-release structure 19; one end of the second body 11 is inserted into the second groove 151, and then the second body 11 is quickly connected to the second bracket 15 through the second quick-release structure 20. The above connection structure not only realizes the detachable connection between the bracket and the body, but also improves the connection efficiency between the two.

[0062] See Figure 5 , Figure 6 , Figure 7 , Figure 8Both the first quick-release structure 19 and the second quick-release structure 20 include a quick-release post 201, a central shaft 202, a guide rod 203, a locking block 204, a connecting rope 205, and a compression spring 206. The quick-release post 201 includes a first section 207 and a second section 208 connected together. One end of the central shaft 202 is disposed inside the quick-release post 201 and rotatably connected to it. The other end of the central shaft 202 extends from the first section 207 to the outside of the quick-release post 201. One end of the guide rod 203 is slidably connected to the second section 208 along its radial direction. The other end of the guide rod 203 is connected to the locking block 204. One end of the connecting rope 205 is connected to the locking block 204. The other end of the connecting rope 205 passes through the second section 208 and is connected to the central shaft 206. 02 connection, the two ends of the compression spring 206 are respectively connected to the locking block 204 and the second segment 208; the first bracket 13 is provided with a first bracket connection hole 132, the first body 10 is provided with a first body connection hole 101, the second bracket 15 is provided with a second bracket connection hole 152, the second body 11 is provided with a second body connection hole 111, and the side walls of the first body connection hole 101 and the second body connection hole 111 are both provided with annular slots 112; the first segment 207 is used to be set in the first bracket connection hole 132 and the second bracket connection hole 152, the second segment 208 is used to be set in the first body connection hole 101 and the second body connection hole 111, and the locking block 204 is used to be set in the annular slot 112.

[0063] See Figure 8The quick-release post 201 comprises a first segment 207 and a second segment 208 from top to bottom. Both segments 207 and 208 are cylindrical, with the outer diameter of the first segment 207 being greater than or equal to the outer diameter of the second segment 208. The quick-release post 201 has a cylindrical inner cavity with an opening at the top. The central shaft 202 is cylindrical, with its outer diameter slightly smaller than the diameter of the inner cavity of the quick-release post 201, allowing it to be positioned within the cavity. A connecting shaft 210 is coaxially mounted at the lower end of the central shaft 202. The outer diameter of the connecting shaft 210 is smaller than the outer diameter of the central shaft 202. The lower end of the connecting shaft 210 is rotatably connected to a fixing plate 211, which is fixed to the bottom of the inner cavity of the quick-release post 201. The upper end of the central shaft 202 extends to the outside of the quick-release post 201, forming an operating end. To facilitate control of the rotation of the central shaft 202, a handle 212 for the operator to grip is connected to the upper end of the central shaft 202. The outer surface of the second section 208 is provided with a guide groove 213 extending radially therein. One end of the guide rod 203 is slidably fitted within the guide groove 213, allowing the guide rod 203 to move radially along the second section 208 under the engagement of the guide groove 213. A locking block 204 is fixed to the other end of the guide rod 203. There can be one or more guide grooves 213. When there are multiple guide grooves 213, they are evenly distributed circumferentially along the second section 208, with a guide rod 203 slidably fitted within each guide groove 213. Each locking block 204 is connected to the connecting shaft 210 via a connecting rope 205, and the second section 208 is provided with a rope hole 214 through which each connecting rope 205 passes. Each locking block 204 is also connected to the second section 208 via a compression spring 206. A fixing groove 215 is provided on the second section 208, directly opposite the compression spring 206. One end of the compression spring 206 is fixed in the fixing groove 215, and the other end of the compression spring 206 abuts or connects with the locking block 204.

[0064] The card block 204 has two states: the retracted state and the latched state. Figure 8 The locking block 204 is in the locked state. When it is necessary to control the locking block 204 to be in the retracted state, simply rotate the central shaft 202 to wind the connecting rope 205 around the connecting shaft 210. The connecting rope 205 drives the locking block 204 to move closer to the second segment 208, and the compression spring 206 is compressed. When the locking block 204 abuts against the second segment 208, the locking block 204 is in the retracted state. When it is necessary to control the locking block 204 to be in the locked state, remove the external force on the central shaft 202. The compression spring 206 provides a reset force, the central shaft 202 rotates in the opposite direction, releasing the connecting rope 205 on the connecting shaft 210. The compression spring 206 drives the locking block 204 to move away from the second segment 208 until the locking block 204 stops moving, at which point the locking block 204 is in the locked state. Regardless of the state of the locking block 204, the guide rod 203 and the guide groove 213 do not disengage and are always in a sliding fit.

[0065] See Figure 5 The first bracket 13 is provided with a first bracket connection hole 132, and the first section 207 of the first quick-release structure 19 is used to be disposed within the first bracket connection hole 132; the second bracket 15 is provided with a second bracket connection hole 152, and the first section 207 of the second quick-release structure 20 is used to be disposed within the second bracket connection hole 152. See also Figure 6 , Figure 7 The first body 10 has a first body connection hole 101 on its first horizontal plate 102, and an annular groove 112 on the side wall of the first body connection hole 101. The second section 208 of the first quick-release structure 19 is disposed within the first body connection hole 101 and is used to engage the locking block 204 in the annular groove 112 within the first body connection hole 101. The second body 11 has a second body connection hole 111 on its second horizontal plate 113, and annular grooves 112 are provided on the side walls of the second body connection hole 111. The second section 208 of the second quick-release structure 20 is disposed within the second body connection hole 111 and is used to engage the locking block 204 in the annular groove 112 within the second body connection hole 111. The dimensions of the first bracket connection hole 132, the second bracket connection hole 152, the first body connection hole 101, and the second body connection hole 111 should ensure that the locking block 204 in the retracted state can pass through these holes.

[0066] To reduce the possibility that the retracted locking block 204 may get stuck in the first bracket connection hole 132, the second bracket connection hole 152, the first body connection hole 101, and the second body connection hole 111, see [reference needed]. Figure 8 The second segment 208 is provided with a receiving groove 209 for accommodating the locking block 204. When the locking block 204 is in the retracted state, the locking block 204 can be completely accommodated in the receiving groove 209, avoiding the possibility that the locking block 204 will get stuck in the first bracket connection hole 132, the second bracket connection hole 152, the first body connection hole 101, and the second body connection hole 111, and preventing the quick-release pin 201 from being unable to be removed from the above holes.

[0067] The installation process of the second quick-release structure 20 is as follows: First, insert one end of the second body 11 into the second groove 151 of the second bracket 15, and align the second body connection hole 111 with the second bracket connection hole 152. Control the locking block 204 in the second quick-release structure 20 to be in the retracted state. Insert the quick-release pin 201 into the second bracket connection hole 152 and the second body connection hole 111 in sequence. Remove the external force on the central shaft 202. Under the action of the compression spring 206, the locking block 204 returns to the locking state and locks into the annular groove 112 of the second body connection hole 111. The removal process of the second quick-release structure 20 is as follows: Rotate the central shaft 202 to make the locking block 204 retracted, and then remove the quick-release pin 201 from the second body connection hole 111 and the second bracket connection hole 152. The installation and removal process of the first quick-release structure 19 is similar to that of the second quick-release structure 20, and will not be described again here.
