Description

Technical Field

[0001] This utility model relates to the field of steel structure support technology, specifically a steel structure support that is easy to install. Background Technology

[0002] Steel structure supports are frameworks that provide support and protection for equipment or the main steel structure. These supports not only provide support but also sometimes facilitate movement for operators. Common steel structure supports include angle steel supports and H-beam supports. In steel structure engineering, the main function of steel supports is to support steel wall frames, steel beams, steel trusses, and other components, ensuring the stability and safety of the entire structure. However, existing steel structure supports mostly use direct welding and fixing of horizontal and vertical members, which is cumbersome to carry to the erection point. Furthermore, once the heavy supports are transported to the temporary site, the frames are difficult to move, resulting in poor usability and certain limitations. In the prior art, such as the steel structure support proposed in announcement number CN223003814U, which is easy to install and disassemble, this technical solution discloses a steel structure support that is easy to install and disassemble, including two opposing columns. The outer surface of each of the two columns is fitted with an adjustment component. A crossbar is detachably connected between the two adjustment components. The crossbar includes a first steel frame and a second steel frame. A symmetrically arranged fixing block is fixedly connected to the side wall of the second steel frame near the first steel frame. A support block is hinged to the top of the fixing block. The end of the support block away from the fixing block is fixed to the side wall of the first steel frame. By setting up a detachably connected crossbar and columns, the crossbar and columns can be easily assembled and disassembled by inserting the connecting sleeves of the adjustment components at both ends of the crossbar. This solves the problem that the crossbars and columns of the existing steel structure supports are mostly directly welded and fixed, which is troublesome when carrying them to the construction site, and improves the convenience of transportation and carrying. However, in the existing steel structure support installation, the connection method between the horizontal bars and the columns is "the connecting sleeves of the adjusting components are inserted at both ends of the horizontal bar," which means that the accuracy requirements for the column spacing are extremely high. If there is a slight error in the spacing between the two columns, the horizontal bar may be too long to be inserted, or too short to cause the connection to loosen. The installation process still needs to be adjusted repeatedly, or even fail. Secondly, the sliding sleeve is fixed by inserting limit bolts. Since there is no limiting mechanism for the limit bolts, the limit bolts may fall off, resulting in low stability of the steel structure support after installation. To address the aforementioned issues, this application proposes a steel structure support that is easy to install. Utility Model Content

[0003] This utility model aims to provide a steel structure support that is easy to install. It is mainly used to solve the problem that if there is a slight error in the spacing between the two columns of the existing steel structure support, the crossbar may be too long to be inserted, or too short to cause the connection to loosen. Moreover, since there is no limiting mechanism for the limiting bolts, the limiting bolts may fall off, resulting in low stability of the steel structure support after installation.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An easy-to-install steel structure support includes two opposing columns and a crossbar. Connecting sleeves are slidably connected to both ends of the outer wall of the crossbar. A first spring is fixedly connected to both ends of the crossbar, with the other end of the first spring fixedly connected to the inner wall of the connecting sleeve. A connecting post is fixedly connected to the end of the connecting sleeve away from the crossbar. Sliding sleeves are slidably connected to each column. A sleeve matching the connecting post is fixedly connected to one side of each sliding sleeve. Limit bolts are slidably connected through and through the sliding sleeves. Multiple through slots matching the limit bolts are provided on the columns. A pull block is fixedly connected to one end of each limit bolt, and a limiting component is provided at the other end to prevent it from falling off.

[0005] The working principle and beneficial effects of this utility model: 1. Working Principle: During installation, first, fix the two uprights in the designated positions using flanges. Then, pull the connecting sleeves at both ends of the crossbar to compress the first spring. Next, align the connecting post at the front end of the connecting sleeve with the sleeve of the sliding sleeve on the upright. Release the connecting sleeve; under the restoring force of the first spring, the connecting post is pushed into the sleeve, completing the quick connection between the crossbar and the upright. The telescopic characteristics of the first spring allow the crossbar to be adjusted within a certain length range, effectively compensating for manufacturing or installation errors in the spacing between the uprights. The sliding sleeve can slide up and down along the upright to adjust the height of the crossbar. When the sliding sleeve moves to the appropriate height, align the limiting bolt with a through slot on the upright and push the limiting bolt through the slot. At this time, the limiting component fixes the limiting bolt to prevent it from falling off, thus firmly locking the sliding sleeve onto the upright.

[0006] 2. Beneficial effects: The telescopic characteristics of the first spring allow the crossbar to be adjusted within a certain length range, effectively compensating for manufacturing or installation errors in the column spacing and reducing the requirements for installation accuracy. The cooperation between the sliding sleeve and the limit bolt enables flexible and multi-level adjustment of the crossbar height to meet different usage needs. The limit component ensures the stability after connection and prevents the sliding sleeve from accidentally sliding due to the limit bolt falling off during use.

[0007] Preferably, the inner wall of the connecting sleeve is fixedly connected with symmetrical guide blocks, and both ends of the crossbar are provided with guide grooves that match the guide blocks. The cooperation between the guide blocks and the guide grooves makes the installation process smoother and more accurate, and can effectively prevent the connecting sleeve from detaching from the crossbar.

[0008] Preferably, the outer wall of the connecting sleeve is provided with grooves, and the inner wall of the grooves is provided with anti-slip ridges. The grooves and anti-slip ridges increase the friction when the hand contacts the connecting sleeve. When it is necessary to manually pull the connecting sleeve to compress the first spring, this design provides a better point of force, prevents slippage, and makes the operation easier and safer.

[0009] Preferably, the corners on the inner wall of the sleeve away from the sliding sleeve are all chamfered, forming a guiding bevel. When the connecting post is inserted into the sleeve, even if there is a slight misalignment, the chamfer can guide and correct the misalignment, making it easier and smoother for the connecting post to slide into the sleeve, further improving the convenience and success rate of installation.

[0010] Preferably, the limiting assembly includes a sliding cavity opened at the end of the limiting bolt away from the pull block, and the sliding cavity is symmetrically arranged on the limiting bolt. A limiting block is slidably connected inside the sliding cavity. The limiting bolt extends from one side of the limiting block, and a symmetrical second spring is fixedly connected to the other side. The other end of the second spring is fixedly connected to the inner wall of the sliding cavity. After the crossbar is slid to a suitable height, the limiting block is pressed to enter the sliding cavity, and the limiting bolt is inserted into the corresponding through slot. When the limiting block has completely passed through the through slot, under the restoring force of the second spring, the limiting block quickly pops out and locks on the outside of the through slot, forming an automatic mechanical lock. This structure realizes the "one-click" locking of the limiting bolt, without additional operation, which is safe and reliable. When unlocking, it is only necessary to press the limiting block to enter the sliding cavity and then pull the pull block to pull out the limiting bolt, thus making disassembly relatively convenient.

[0011] Preferably, the limiting block extends from one side of the limiting bolt and is rotatably connected to multiple ball bearings, which are distributed in a linear array at equal intervals on the limiting block. When the limiting block contacts the inner wall of the through groove, the ball bearings convert sliding friction into rolling friction. This greatly reduces the friction of the limiting bolt during insertion and removal, making operation easier and smoother, and extending the service life of the component.

[0012] Preferably, the corner of the limiting block extending from the limiting bolt and away from the pull block is set with an inclined surface. When the limiting bolt is inserted, the inclined surface of the limiting block is squeezed and will automatically slide into the sliding cavity. This eliminates the need for manual pressing of the limiting block to enter the sliding cavity, making the installation of the steel structure bracket more convenient and improving the user experience.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 A steel structure bracket that is easy to install includes two opposing columns 1 and a crossbar 2. Both ends of the outer wall of the crossbar 2 are slidably connected to connecting sleeves 3. Both ends of the crossbar 2 are fixedly connected to a first spring 4. The other end of the first spring 4 is fixedly connected to the inner wall of the connecting sleeve 3. The end of the connecting sleeve 3 away from the crossbar 2 is fixedly connected to a connecting post 5. Sliding sleeves 6 are slidably connected to each column 1. One side of each sliding sleeve 6 is fixedly connected to a sleeve 7 that matches the connecting post 5. Pulling the connecting sleeves 3 at both ends of the crossbar 2 compresses the first spring 4. Then, the connecting post 5 at the front end of the connecting sleeve 3 is aligned with the sleeve 7 of the sliding sleeve 6 on the column 1. The connecting sleeve 3 is released. Under the restoring force of the first spring 4, the connecting post 5 is pushed into the sleeve 7, completing the quick connection between the crossbar 2 and the column 1. The telescopic characteristics of the first spring 4 allow the crossbar 2 to be adjusted within a certain length range, effectively compensating for manufacturing or installation errors in the spacing of the columns 1. A limiting bolt 8 is slidably connected through the sliding sleeve 6. Multiple through slots 9 matching the limiting bolt 8 are provided on the column 1. One end of the limiting bolt 8 is fixedly connected to a pull block 18, and the other end is equipped with a limiting component to prevent it from falling off. The sliding sleeve 6 can slide up and down along the column 1 to adjust the height of the crossbar 2. When the sliding sleeve 6 moves to a suitable height, the limiting bolt 8 is aligned with a certain through slot 9 on the column 1, and the limiting bolt 8 is pushed to pass through the through slot 9. At this time, the limiting component fixes the limiting bolt 8, preventing it from falling off, thereby firmly locking the sliding sleeve 6 onto the column 1.

[0017] More specifically, the inner wall of the connecting sleeve 3 is fixedly connected with symmetrical guide blocks 10, and both ends of the crossbar 2 are provided with guide grooves 11 that match the guide blocks 10. The cooperation between the guide blocks 10 and the guide grooves 11 makes the installation process smoother and more accurate, and can effectively prevent the connecting sleeve 3 from detaching from the crossbar 2.

[0018] More specifically, the outer wall of the connecting sleeve 3 is provided with grooves 12, and the inner wall of the grooves 12 is provided with anti-slip ridges 17. The grooves 12 and the anti-slip ridges 17 increase the friction when a person's hand comes into contact with the connecting sleeve 3. When it is necessary to manually pull the connecting sleeve 3 to compress the first spring 4, this design provides a better point of force, prevents slippage, and makes the operation easier and safer.

[0019] More specifically, the corners on the inner wall of sleeve 7 away from sliding sleeve 6 are all chamfered, forming a guiding bevel. When the connecting post 5 is inserted into sleeve 7, even with slight alignment deviations, the chamfer can guide and correct the deviation, making it easier and smoother for the connecting post 5 to slide into sleeve 7, further improving the convenience and success rate of installation.

[0020] More specifically, the limiting component includes a sliding cavity 13 opened at the end of the limiting bolt 8 away from the pull block 18, and the sliding cavity 13 is symmetrically arranged on the limiting bolt 8. A limiting block 14 is slidably connected inside the sliding cavity 13. The limiting bolt 8 extends out from one side of the limiting block 14, and a symmetrical second spring 15 is fixedly connected to the other side. The other end of the second spring 15 is fixedly connected to the inner wall of the sliding cavity 13. After sliding the crossbar 2 to a suitable height, press the limiting block 14 to allow it to enter the sliding cavity 13 while simultaneously inserting the limiting bolt 8 into the corresponding through slot 9. When the limiting block 14 has completely passed through the through slot 9, under the restoring force of the second spring 15, the limiting block 14 quickly pops out and locks onto the outside of the through slot 9, forming an automatic mechanical lock. This structure achieves "one-click" locking of the limiting bolt 8, requiring no additional operation, and is safe and reliable. Unlocking is also convenient; simply press the limiting block 14 to allow it to enter the sliding cavity 13 and then pull the pull block 18 to pull out the limiting bolt 8.

[0021] More specifically, the limiting block 14 extends from one side of the limiting bolt 8 and is rotatably connected to multiple ball bearings 16. These ball bearings 16 are arranged in a linear array and equidistantly on the limiting block 14. When the limiting block 14 contacts the inner wall of the through groove 9, the ball bearings 16 convert sliding friction into rolling friction. This significantly reduces the frictional force of the limiting bolt 8 during insertion and removal, making operation easier and smoother, and extending the service life of the component.

[0022] More specifically, the corner of the limiting block 14 extending from the limiting bolt 8 and away from the pull block 18 is set with a slope. When the limiting bolt 8 is inserted, the slope of the limiting block 14 is squeezed and will automatically slide into the sliding cavity 13. This eliminates the need for manual pressing of the limiting block 14 to enter the sliding cavity 13, making the installation of the steel structure bracket more convenient and improving the user experience.

[0023] As can be seen from the above, the specific embodiments of this utility model are as follows: During installation, first fix the two uprights 1 in the designated position using flanges, then pull the connecting sleeves 3 at both ends of the crossbar 2 to compress the first spring 4, then align the connecting post 5 at the front end of the connecting sleeve 3 with the sleeve 7 of the upper sliding sleeve 6 of the upright, release the connecting sleeve 3, and under the restoring force of the first spring 4, the connecting post 5 is pushed into the sleeve 7, completing the quick connection between the crossbar 2 and the upright 1. The telescopic characteristics of the first spring 4 allow the crossbar 2 to be adjusted within a certain length range, effectively compensating for manufacturing or installation errors in the spacing of the columns 1. (The crossbar includes a first steel frame and a second steel frame. The bottom of the first steel frame near the second steel frame has symmetrically arranged positioning holes. The bottom of the second steel frame facing the first steel frame has two opposing stabilizing rods fixedly connected. The end of the stabilizing rod away from the second steel frame is inserted into the positioning hole. The top of the fixing block near the first steel frame has a sliding opening. The inner wall of the sliding opening is fixedly connected with a protruding bolt. The end of the support block away from the first steel frame has a rotating hole, which is fitted onto the outer surface of the protruding bolt.) The part in parentheses is prior art, which is not described in detail in this application. The sliding sleeve 6 can slide up and down along the column 1 to adjust the height of the crossbar 2. Once the sliding sleeve 6 has moved to the appropriate height, align the limiting bolt 8 with a slot 9 on the column 1 and push the limiting bolt 8 to pass through the slot 9. When the limiting bolt 8 is inserted, the inclined surface of the limiting block 14 is compressed and automatically slides into the sliding cavity 13. After the limiting block 14 has completely passed through the slot 9, under the restoring force of the second spring 15, the limiting block 14 quickly pops out and locks onto the outside of the slot 9, forming an automatic mechanical lock. This structure achieves "one-click" locking of the limiting bolt 8, requiring no additional operation, and is safe and reliable. At this point, the assembly of the steel structure support is complete.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
