Description

Technical Field

[0001] This utility model relates to the field of sleeve fixation technology, specifically a weld-free through-beam sleeve fixation device. Background Technology

[0002] Sleeve fasteners are primarily used to secure and protect sleeves, such as through-beam sleeves and steel sleeves, ensuring their stability and reliability during use. They prevent sleeves from shifting or being damaged during operation, thereby improving construction efficiency and safety. Sleeve fasteners come in various types, and depending on the sleeve material and application, they can be categorized as PVC through-beam sleeve fasteners, steel sleeve fasteners, etc. These fasteners typically consist of two parts: a clamp for securing the sleeve, and a bracket for fixing the clamp to the beam head or other structure.

[0003] However, existing sleeve fixing devices require multiple bolts to secure them to the wooden formwork in actual use, which is complicated and time-consuming. Furthermore, the bolt installation direction is perpendicular to the side wall of the wooden formwork, and the limited internal operating space of the wooden formwork makes bolt installation inconvenient. To address this issue, a weld-free through-beam sleeve fixing device is provided. Utility Model Content

The limiting assembly is located at the bottom of the inner cavity of the frame and is fixedly connected to the bottom of the two sliders. One end of each of the two moving rods is fixedly connected to the top of the two sliders, and the other end of each of the two moving rods is fixedly connected to two retainers. The driving assembly is located at the top of the base and is fixedly sleeved on the outer wall of the lead screw.

[0006] Preferably, the threads on both sides of the outer wall of the lead screw are arranged opposite to each other.

[0007] Preferably, the limiting component includes a limiting groove and limiting blocks. The limiting groove is formed at the bottom of the inner cavity of the frame, and the two limiting blocks are slidably embedded in the inner cavity of the limiting groove and are respectively fixedly connected to the bottom ends of the two sliders.

[0008] Preferably, the inner cavity of the limiting groove and the outer wall of the limiting block are adapted to each other and are both in the shape of a "T".

[0009] Preferably, the drive assembly includes a worm, a disc, a worm wheel, and a cross groove. One end of the worm is rotatably connected to the top of the base via a bearing. The disc is disposed at the top of the worm, the cross groove is formed at the top of the disc, and the worm wheel is fixedly sleeved on the middle of the lead screw.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution: a weld-free through-beam sleeve fixer, including a sleeve 1, with fixers 2 slidably fitted at both ends of the sleeve 1. Each fixer 2 is provided with multiple fixing plates 3, and each fixing plate 3 is provided with a fixing cone 4. A base 5 is provided at the top of the sleeve 1, and a frame 6 is provided at the top of the base 5. A sliding component is provided in the inner cavity of the frame 6. The sliding component is fixedly connected to two fixers 2. By sliding the component, the two fixers 2 are simultaneously slid away from the sleeve 1, thereby allowing the fixing cone 4 to be inserted into the interior of the wooden template until the outer wall of the fixer 2 is tightly fitted with the wooden template, thus fixing the sleeve 1. The operation is simple and convenient. This invention solves the problem that existing technologies require multiple bolts to fix the sleeve 1 and the fixing device 2 in the wooden template, which is complicated, time-consuming, and time-consuming. By setting up the worm gear 12 and the worm wheel, the driving direction of the rotating screw 7 can be changed. The worm gear 12 can be rotated vertically in the opening above the wooden template for installation. This solves the problem that the bolt installation direction is perpendicular to the side wall of the wooden template, and the internal operating space of the wooden template is narrow, making bolt installation inconvenient. By setting up the worm gear 12 and the worm wheel, the self-locking effect of the two can prevent loosening after the fixing device 2 and the sleeve 1 are installed in the wooden template, thus improving the practicality of the device in use.

[0025] In this embodiment, the sliding assembly includes a lead screw 7, sliders 8, a limiting assembly, moving rods 9, and a driving assembly. The two ends of the lead screw 7 are rotatably connected to the two ends of the inner cavity of the frame 6 via bearings. Two sliders 8 are screwed onto both sides of the outer wall of the lead screw 7. The limiting assembly is located at the bottom of the inner cavity of the frame 6 and is fixedly connected to the bottom ends of the two sliders 8. One end of each moving rod 9 is fixedly connected to the top end of each slider 8, and the other end of each moving rod 9 is fixedly connected to two retainers 2. The driving assembly is located at the top of the base 5 and is fixedly sleeved on the outer wall of the lead screw 7. The driving assembly drives the lead screw 7 to rotate, thereby causing the outer wall of the lead screw 7 to... The opposing threads on both sides generate opposing thread rotational forces, causing the two sliders 8 to slide simultaneously towards both ends of the screw 7 under the limiting action of the limiting groove 10 and the limiting block 11. This causes the two moving rods 9 to drive the two fixing devices 2 to slide simultaneously away from the sleeve 1, thereby allowing the fixing cone 4 to be inserted into the interior of the wooden template until the outer wall of the fixing device 2 is tightly fitted with the wooden template, thus achieving the fixing of the sleeve 1. The operation is simple and convenient, solving the problem that the existing sleeve 1 fixing device 2 requires multiple bolts to fix it in the wooden template in actual use, which is complicated, troublesome and time-consuming.

[0026] In this embodiment, the threads on both sides of the outer wall of the lead screw 7 are arranged opposite to each other, so that when the lead screw 7 rotates, the left and right sides of its outer wall generate relative thread rotation force, so that the two sliders 8 slide relative to each other simultaneously under the limiting action of the limiting groove 10 and the limiting block 11.

[0027] In this embodiment, the limiting component includes a limiting groove 10 and limiting blocks 11. The limiting groove 10 is formed at the bottom of the inner cavity of the frame 6. The two limiting blocks 11 are slidably embedded in the inner cavity of the limiting groove 10 and are respectively fixedly connected to the bottom of the two sliders 8. Under the joint action of the limiting groove 10 and the limiting blocks 11, the sliders 8 can be prevented from rotating with the lead screw 7 when the lead screw 7 rotates, thus improving the stability of the sliding component during use.

[0028] In this embodiment, the inner cavity of the limiting groove 10 and the outer wall of the limiting block 11 are adapted to each other and are both in the shape of a "T". This allows one end of the limiting block 11 to always remain embedded in the inner cavity of the limiting groove 10, thereby improving the stability of the limiting component during use.

[0029] In this embodiment, the drive assembly includes a worm gear 12, a disc 13, a worm wheel, and a cross groove 14. One end of the worm gear 12 is rotatably connected to the top of the base 5 via a bearing. The disc 13 is disposed at the top of the worm gear 12, and the cross groove 14 is formed at the top of the disc 13. The worm wheel is fixedly sleeved on the middle of the lead screw 7. An electric drill drives a cross wrench to rotate the disc 13 and the worm gear 12 through the cross groove 14. Since the worm gear 12 meshes with the worm wheel, when the worm gear 12 rotates, the worm wheel can drive the lead screw 7 to rotate. By setting up the worm gear 12 and worm wheel, the driving direction of the rotating screw 7 can be changed. The worm gear 12 can be installed vertically in the opening above the wooden template, which solves the problem that the bolt installation direction is perpendicular to the side wall of the wooden template and the internal operating space of the wooden template is small and inconvenient for bolt installation. By setting up the worm gear 12 and worm wheel, the self-locking effect of the two can be used to prevent loosening after the fixing device 2 and the sleeve 1 are installed in the wooden template, thus improving the practicality of the device in use.

[0030] In this embodiment, the worm 12 meshes with the worm wheel, so that the worm 12 can drive the worm wheel to rotate when it rotates.

[0031] In this embodiment, the outer circumference of the disc 13 is provided with anti-slip ridges, which can be used to rotate the worm gear 12 by manually rotating the disc 13 when there is no screwdriver. The anti-slip ridges can improve the roughness of the outer circumference and prevent the disc 13 from slipping out of your hand when rotating.

[0032] In this embodiment, the fixed cone 4 is a stainless steel cone, which can improve the strength of the fixed cone 4 and prevent it from deforming or bending.

[0033] In this embodiment, anti-slip ridges are provided on the sides of the two fasteners 2 that are far apart from each other, which can improve the friction when the outer wall of the fastener 2 comes into contact with the wooden template.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
