Description

Technical Field

[0001] This utility model relates to the field of membrane structure technology, and in particular to a tensioning component for a membrane structure. Background Technology

[0002] Membrane structures are a type of architectural and structural system that combines architecture and structure. They use high-strength flexible membrane materials and auxiliary structures to generate a certain pre-stress within them and form a certain spatial shape under stress control. This serves as a covering structure or the main body of a building and has sufficient rigidity to resist external loads. Membrane structures are lightweight, have good seismic performance, and do not require internal support. They overcome the difficulties encountered by traditional structures in large-span (unsupported) buildings and can create huge unobstructed visual spaces, effectively increasing the usable space area.

[0003] An existing membrane structure tensioning assembly presents a challenge for operators, who may find the tensioning operation difficult or even impossible. This not only reduces work efficiency but may also increase the operator's workload and affect the overall ease of operation when the equipment is used to perform tension testing on the product. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a tensioning component for a membrane structure.

[0005] This utility model is achieved by the following technical solution: a tensioning component for a membrane structure, including a supporting base plate, a fixed sleeve fixedly connected inside the supporting base plate, a supporting retaining ring fixedly connected inside the supporting base plate, a lead screw threadedly connected inside the supporting retaining ring, an adjustable sliding groove opened on the top of the supporting base plate, and a ball sleeve threadedly connected to the surface of the lead screw.

[0006] A support frame is fixedly connected to the top of the ball sleeve, and a vertical plate is fixedly connected to the top of the support frame. A first limiting rod is fixedly connected inside the vertical plate, and a limiting block is engaged with the surface of the first limiting rod. A fixing screw is threaded into the internal part of the limiting block. A limiting frame is fixedly connected to the top of the support base plate, and a second limiting rod is fixedly connected inside the limiting frame. A fixing plate is rotatably connected inside the limiting frame, and a handle is fixedly connected to the top of the fixing plate. Connecting plates are fixedly connected to the left and right ends of the fixing plate, and connecting screws are threaded into the internal parts of the connecting plates.

[0007] Through the above technical solution, the sliding connection between the support frame and the adjustable slide rails allows the height of the support frame to be adjusted by rotating the lead screw. The two adjustable slide rails are symmetrically distributed front and back around the support base plate, ensuring the stability of the support frame during lifting. This design provides great flexibility for the height requirements of the entire device in different working scenarios.

[0008] As a further improvement to the above solution, the lead screw is threaded inside the fixed sleeve, and the number of the adjusting grooves is set to two, which are symmetrically distributed front and back with the supporting base plate as the center.

[0009] As a further improvement to the above solution, the support frame is slidably connected inside the adjustable groove, and the support frame is slidably connected inside the support base plate.

[0010] As a further improvement to the above solution, the number of connecting plates and connecting screws is set to two, and the two connecting plates and connecting screws are symmetrically distributed around the fixing plate.

[0011] With the above technical solution, the two adjustable sliding grooves, two fixed screws, two connecting plates and connecting screws are symmetrically distributed around the corresponding components, which has the property of force balance, reduces local stress concentration, and thus extends the service life of the device.

[0012] As a further improvement to the above solution, the connecting screw passes through the connecting plate and the limiting frame, and the support frame is located at the top of the screw.

[0013] As a further improvement to the above solution, the limiting block is engaged with the front of the upright plate, and the fixing plate is engaged with the inside of the limiting frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a rotating screw inside the fixed sleeve and support ring to drive the ball sleeve and support frame on the surface to move back and forth within the support base plate and adjusting groove. When the connecting screw is rotated to remove the product from inside the limiting frame and fixed plate, one end of the product is wound around the second limiting rod. Pulling the handle causes the fixed plate to engage with the front of the limiting frame, and then it is fixed with the connecting plate and connecting screw. The other end of the product is then wound around the surface of the first limiting rod and fixed with the limiting block and fixed screw. When the screw drives the support frame and upright plate to move, it facilitates operation for workers when performing tension tests on the product and reduces tension imbalance during product tensioning.

[0016] The second limiting rod inside the limiting frame and the snap-fit ​​structure of the fixing plate, along with the design of the connecting screw passing through the connecting plate and the limiting frame, make the connection between the various components more stable and ensure the stability of the entire device during operation.

A handle 15 is fixedly connected to the top of the fixing plate 14. Connecting plates 16 are fixedly connected to the left and right ends of the fixing plate 14. Connecting screws 17 are threadedly connected inside the connecting plates 16. By rotating the screw 4 inside the fixed sleeve 2 and the support retaining ring 3... The ball bearing sleeve 6 and support frame 7 on the drive surface move back and forth within the support base plate 1 and the adjusting groove 5. When the connecting screw 17 is rotated to remove the product from inside the limiting frame 12 and the fixing plate 14, one end of the product is wrapped around the second limiting rod 13. Pulling the handle 15 causes the fixing plate 14 to engage with the front of the limiting frame 12, and then it is fixed with the connecting plate 16 and the connecting screw 17. The other end of the product is wrapped around the surface of the first limiting rod 9, and it is fixed with the limiting block 10 and the fixing screw 11. When the screw 4 drives the support frame 7 and the upright plate 8 to move in position, it facilitates the operation of the staff when performing tension tests on the product and reduces the tension imbalance during product tensioning.

[0028] The sliding connection between the support frame 7 and the adjustable slide rail 5 allows the height of the support frame 7 to be adjusted by rotating the lead screw 4. The two adjustable slide rails 5 are symmetrically distributed front and back with the support base plate 1 as the center, ensuring the stability of the support frame 7 during the lifting process. This design provides great flexibility for the height requirements of the entire device in different working scenarios.

[0029] The lead screw 4 is threaded inside the fixed sleeve 2. The number of adjustable grooves 5 is set to two, and the two adjustable grooves 5 are symmetrically distributed front and back with the supporting base plate 1 as the center.

[0030] The support frame 7 is slidably connected inside the adjustable groove 5, and the support frame 7 is slidably connected inside the support base plate 1.

[0031] The number of connecting plates 16 and connecting screws 17 is set to two, and the two connecting plates 16 and connecting screws 17 are symmetrically distributed with the fixing plate 14 as the center.

[0032] The two adjustable grooves 5, the two fixing screws 11, the two connecting plates 16 and the connecting screws 17 are symmetrically distributed around the corresponding components, which has the property of force balance, reduces the situation of local stress concentration, and thus extends the service life of the device.

[0033] The connecting screw 17 passes through the connecting plate 16 and the limiting frame 12. The support frame 7 is located at the top of the screw 4. The second limiting rod 13 inside the limiting frame 12 and the snap-fit ​​structure of the fixing plate 14, along with the design of the connecting screw 17 passing through the connecting plate 16 and the limiting frame 12, make the connection between the various components more stable and ensure the stability of the entire device during operation.

[0034] The limiting block 10 is engaged with the front of the upright plate 8, and the fixing plate 14 is engaged with the inside of the limiting frame 12.

[0035] The implementation principle of a membrane structure tensioning assembly in this embodiment is as follows: By rotating the screw 4 inside the fixed sleeve 2 and the support ring 3, the ball sleeve 6 and the support frame 7 on the surface move back and forth within the support base plate 1 and the adjusting groove 5. When the connecting screw 17 is rotated out from inside the limiting frame 12 and the fixed plate 14, one end of the product is wrapped around the second limiting rod 13. Pulling the handle 15 causes the fixed plate 14 to engage with the front of the limiting frame 12. Then, it is fixed with the connecting plate 16 and the connecting screw 17. The other end of the product is then... The end is wound onto the surface of the first limiting rod 9 and fixed with the limiting block 10 and the fixing screw 11. When the lead screw 4 drives the support frame 7 and the upright plate 8 to move in position, it facilitates the operation of the staff when performing tension tests on the product and reduces the tension imbalance when the product is tensioned. The snap-fit ​​structure of the second limiting rod 13 inside the limiting frame 12 and the fixing plate 14, plus the design of the connecting screw 17 passing through the connecting plate 16 and the limiting frame 12, makes the connection between the various components more stable and ensures the stability of the entire device during operation.
