Description

Technical Field

[0001] This utility model belongs to the field of steel structure connection technology, and in particular relates to a steel sleeve locking mechanism for steel structure buildings. Background Technology

[0002] Steel structure buildings are a new type of building system, typically composed of load-bearing components such as beams, columns, and trusses made of steel profiles and plates. Compared to traditional concrete buildings, steel plates or profiles replace reinforced concrete, resulting in higher strength, better earthquake resistance, and significantly reduced construction time because components can be factory-made and installed on-site. In steel structure buildings, steel sleeves are often used to connect with steel beams to secure them.

[0003] Currently, in steel structure buildings, the connection between steel sleeves and steel beams is usually achieved by locking and fixing with multiple bolts and nuts. The fixing process involves a large amount of work, is time-consuming, and requires personnel to carry tools, which is inconvenient.

[0004] Therefore, it is necessary to provide a new steel sleeve locking mechanism for steel structure buildings to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a steel sleeve locking mechanism for steel structure buildings that is simple to operate, time-saving, and can be completed without the use of tools, so as to solve the problems existing in the prior art.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A steel sleeve locking mechanism for steel structure buildings includes a steel sleeve and a steel beam disposed within the steel sleeve. Multiple circular locking holes are provided on the outer walls of both sides of the steel beam. Mounting plates are provided on both sides of the steel sleeve. Multiple locking pins are fixedly installed on the outer walls of the two mounting plates that are close to each other. The ends of the locking pins away from their respective mounting plates extend into the steel sleeve, and each locking pin passes through a corresponding circular locking hole and is slidably connected to the inner wall of the corresponding circular locking hole. Two retaining springs are fixedly installed on the outer walls of both sides of the steel sleeve. The ends of the retaining springs away from the steel sleeve are fixedly connected to the corresponding mounting plates. Two square sleeves are fixedly installed on the top of the steel sleeve. An L-shaped operating rod is slidably installed through and within each of the two square sleeves. The bottom ends of the two L-shaped operating rods are fixedly connected to the corresponding mounting plates.

[0008] Furthermore, positioning blocks are welded to both the top and bottom of the steel beam, and both positioning blocks are in contact with the steel sleeve.

[0009] Furthermore, end blocks are fixedly installed at the top of both L-shaped operating levers.

[0010] Furthermore, both square sleeves have round insertion holes at their tops, and both L-shaped operating rods have round slots at their tops. A fixing rod is fixedly installed on the top of the steel sleeve, and a movable plate is movably fitted on the fixing rod. Two plugs are fixedly installed at the bottom of the movable plate.

[0011] Furthermore, two fixing blocks are fixedly installed at the bottom of the mounting plate. Square slots are opened on the outer wall of the two fixing blocks near the steel sleeve. Two abutment rods are rotatably installed on the outer walls of both sides of the steel sleeve. The same connecting rod is fixedly installed on the two abutment rods on the same side.

[0012] Furthermore, multiple finger slots are provided on both sides of the mounting plate.

[0013] This utility model has the following beneficial effects:

[0014] This utility model provides a steel sleeve locking mechanism for steel structure buildings. It comprises a mounting plate, multiple locking pins, two square sleeves, two L-shaped operating rods, multiple retaining springs, a fixed rod, a movable plate, and plugs. In use, pushing the two L-shaped operating rods to either side causes the two mounting plates to move in opposite directions. This movement of the mounting plates disengages the locking pins from the steel beam, preventing obstruction during insertion. Inserting the two plugs on the movable plate into the circular slots on the L-shaped operating rods prevents the mounting plates from resetting, eliminating the need for manual intervention. Once the steel beam is inserted, pulling the movable plate upwards releases the restriction on the L-shaped operating rods. Under the tension of the retaining springs, the two mounting plates automatically move closer to the steel sleeve, and the locking pins on the mounting plates automatically insert into the corresponding circular locking holes on the steel beam, thus locking the steel beam. This mechanism is simple to operate, time-saving, and requires no tools. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0024] The steel sleeve locking mechanism for steel structure buildings includes: a steel sleeve 1 and a steel beam 2 installed inside the steel sleeve 1. Multiple circular locking holes 201 are provided on both outer walls of the steel beam 2. Mounting plates 3 are provided on both sides of the steel sleeve 1. Multiple locking pins 6 are fixedly installed on the outer walls of the two mounting plates 3 that are close to each other. The diameter of the locking pins 6 is the same as the diameter of the circular locking holes 201. The ends of the multiple locking pins 6 away from their corresponding mounting plates 3 extend into the steel sleeve 1. Limiting circular holes are provided on both outer walls of the steel sleeve 1, and the diameter of the limiting circular holes is the same as that of the locking pins 6. The locking pins 6 pass through the limiting circular holes and slide against the inner walls of the limiting circular holes. Multiple locking pins 6 also pass through their corresponding circular locking holes 201 and slide against the inner walls of the corresponding circular locking holes 201. Through the cooperation of the locking pins 6 and the circular locking holes 201, the steel beam 2 is locked, preventing it from exiting the steel sleeve 1. The connection between the end face of the locking pin 6 away from the mounting plate 3 and its outer peripheral wall is circular. The angled design allows the locking pin 6 to be inserted more smoothly into the round lock hole 201. Two retaining springs 7 are fixedly installed on the outer walls of both sides of the steel sleeve 1. The end of the retaining spring 7 away from the steel sleeve 1 is fixedly connected to the corresponding mounting plate 3. The retaining spring 7 applies an initial tension to the mounting plate 3, so that the locking pin 6 is always located in the round lock hole 201. Two square sleeves 4 are fixedly installed on the top of the steel sleeve 1. An L-shaped operating rod 5 is slidably installed through each of the two square sleeves 4. The bottom ends of the two L-shaped operating rods 5 are fixedly connected to the corresponding mounting plates 3. Before inserting the steel beam 2, the two square L-shaped operating rods 5 are pushed to the sides with the thumb and forefinger respectively (so that the two L-shaped operating rods 5 move in opposite directions). The two L-shaped operating rods 5 drive the corresponding mounting plates 3 to move, so that the two mounting plates 3 are away from the steel sleeve 1. The two mounting plates 3 drive the corresponding locking pin 6 to move, so that the locking pin 6 is no longer located in the steel sleeve 1 and will not hinder the insertion of the steel beam 2.

[0025] In this embodiment, in order to limit the insertion depth of the steel beam 2, positioning blocks are welded to the top and bottom of the steel beam 2. Both positioning blocks are in contact with the steel sleeve 1. When the positioning blocks abut against the steel sleeve 1, they cannot be inserted further. At this time, multiple locking pins 6 are axially aligned with the corresponding circular locking holes 201.

[0026] In this embodiment, in order to reduce the pressure on the hand when pushing the L-shaped operating lever 5, an end block 13 is fixedly installed at the top of each of the two L-shaped operating levers 5. The end block 13 also has the function of restricting the L-shaped operating lever 5 so that the L-shaped operating lever 5 will not detach from the square sleeve 4.

[0027] In this embodiment, the tops of the two square sleeves 4 are provided with round insertion holes 401, and the tops of the two L-shaped operating rods 5 are provided with round slots 501. The top of the steel sleeve 1 is fixedly installed with a fixing rod 8, and a movable plate 9 is movably sleeved on the fixing rod 8. Two plugs 10 are fixedly installed at the bottom of the movable plate 9. When the two L-shaped operating rods 5 are pushed to the sides respectively, after the two end blocks 13 contact the corresponding square sleeves 4 respectively, the two round slots 501 are axially aligned with the corresponding round insertion holes 401. Then, the movable plate 9 is lifted upward until the two plugs 10 move above the square sleeves 4. Then, the movable plate 9 is rotated ninety degrees so that the two plugs 10 are aligned with the two round insertion holes 401 respectively. Finally, the movable plate 9 is released so that the two plugs 10 are inserted into the corresponding round insertion holes 401 and round slots 501 respectively. This prevents the two L-shaped operating rods 5 from resetting, and correspondingly, the multiple locking pins 6 cannot be reset.

[0028] In this embodiment, two fixing blocks 11 are fixedly installed at the bottom of the mounting plate 3. A square slot 1101 is provided on the outer wall of the side of the two fixing blocks 1 closest to the steel sleeve 1. Two abutting rods 12 are rotatably installed on the outer walls of both sides of the steel sleeve 1. The same connecting rod is fixedly installed on the two abutting rods 12 on the same side. For operators with less strength, the mounting plate 3 can be pulled away from the steel sleeve 1 in sequence to make the locking pin 6 disengage from the steel sleeve 1. Then, the corresponding two abutting rods 12 are rotated upward until the abutting rods 12 are in a horizontal state and the bottom of the abutting rods 12 away from the steel sleeve 1 abuts against the corresponding square slot 1101. This can also prevent the mounting plate 3 from resetting.

[0029] In this embodiment, in order to facilitate the operator to pull the mounting plate 3, multiple finger grooves are provided on both sides of the mounting plate 3.

[0030] The working principle of the steel sleeve locking mechanism for steel structure buildings provided by this utility model is as follows:

[0031] When installing steel beam 2, first use your index finger and thumb to push the two end blocks 13 respectively, causing the two L-shaped operating rods 5 to move in opposite directions. The two L-shaped operating rods 5 push the two mounting plates 3 to move, so that the two mounting plates 3 are away from the steel sleeve 1. The locking pins 6 will also gradually move outward from the steel sleeve 1 under the action of the mounting plates 3. When the two end blocks 13 contact the corresponding square sleeves 4, at this time, the multiple locking pins 6 are no longer located inside the steel beam 2, and at this time, the two round insertion holes 401 are axially aligned with the corresponding round slots 501. Then lift the movable plate 9 upward until the two plugs 10 move above the square sleeves 4, and then rotate the movable plate 9 ninety degrees. In this way, the two plugs 10 Then, the two plugs 10 can be aligned with the two round holes 401 respectively. Then, slowly release the movable plate 9 so that the two plugs 10 will be inserted into the corresponding round holes 401 and round slots 501 respectively. In this way, the two L-shaped operating rods 5 cannot be reset, and correspondingly, the multiple locking pins 6 cannot be reset. If it is difficult for operators with less strength to push the two L-shaped operating rods 5 at the same time, they can directly pull the two mounting plates 3 in sequence to move the mounting plates 3 away from the steel sleeve 1, and then rotate the corresponding two abutment rods 12 upwards and insert the ends of the two abutment rods 12 near the connecting rod into the two square slots 1101. This can also prevent the mounting plates 3 from being reset.

[0032] After completing the above steps, insert the steel beam 2 into the steel sleeve 1 until the positioning block on the steel beam 2 contacts the steel sleeve 1. At this point, multiple locking pins 6 are axially aligned with their corresponding circular locking holes 201. Then, the movable plate 9 can be pulled upwards. The movable plate 9 drives the two plugs 10 to move upwards, causing the plugs 10 to exit the circular slots 501. This removes the restriction on the two L-shaped operating rods 5. Under the tension of the retaining spring 7, the two mounting plates 3 will approach the steel sleeve 1. The mounting plates 3 drive the locking pins 6 to move, causing the locking pins 6 to insert into the circular locking holes 201 on the steel beam 2, thus locking the steel beam 2. Because of the tension applied by the retaining spring 7... The initial tension prevents the mounting plate 3 from pulling the steel sleeve 1, and the locking pin 6 will always be in the corresponding round locking hole 201, thus achieving reliable locking of the steel beam 2. When the mounting plate 3 is pulled open by the abutment rod 12 to prevent it from resetting, after the steel beam 2 is inserted into place, the mounting plate 3 is first pulled away from the steel sleeve 1, so that the fixing block 11 is away from the abutment rod 12. Under the action of gravity, the abutment rod 12 will automatically rotate downward. Then the mounting plate 3 is released. Under the tension of the spring 7, the mounting plate 3 will move closer to the steel sleeve 1, so that the locking pin 6 can finally be inserted into the round locking hole 201 on the steel beam 2.

Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
