Description

Technical Field

[0001] This utility model relates to the field of construction tools technology, specifically to a construction support frame with a self-locking buckle. Background Technology

[0002] Construction support frames are a common auxiliary tool in the construction industry. They are mainly used to support and build temporary work platforms, and can also be used to temporarily support some building components. In order to facilitate transportation and transfer, as well as use in different scenarios, construction support frames are always temporarily erected.

[0003] However, existing building support frames still have the following defects during the construction process:

[0004] 1. Existing building support frames require adjustment to the appropriate length based on the different support heights before fixing. The adjustment and fixing process is cumbersome, reducing the efficiency of building support frame construction. Furthermore, once the length is fixed, the support frame cannot be further extended and compacted, thus failing to guarantee stable support and making it prone to loosening after prolonged use.

[0005] 2. After a single building support frame is erected, it is sometimes necessary to connect them together with connecting rods to improve stability. Therefore, connectors for fixing are welded to the outer perimeter of the middle part of the single building support frame. However, although the connectors for fixing the existing building support frame have evenly spaced waist holes on the outer perimeter for easy assembly, the position and tilt angle of the waist holes are not adjustable. Therefore, the convenience of connecting rod installation still needs to be improved. Utility Model Content

[0006] The purpose of this utility model is to solve the problems of cumbersome construction operation, low efficiency, and the need to improve the convenience of connecting rods between construction support frames. This utility model provides a construction support frame with a self-locking buckle.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A building support frame with a self-locking buckle includes a column, a base fixedly installed at the bottom of the column, a sleeve rotatably connected to the top periphery of the column, an internal thread on the inner side of the sleeve, a sliding sleeve slidably connected to the inner side of the top of the column, threaded protrusions evenly fixedly connected to the outer periphery of the sliding sleeve, limit grooves evenly opened at the top and bottom of the inner side of the sliding sleeve, a hydraulic cylinder inserted into the inner side of the sliding sleeve, a plunger buckle evenly slidably connected to the middle periphery of the hydraulic cylinder, a piston rod slidably connected to the top of the hydraulic cylinder, a support base fixedly installed at the top of the piston rod, and a series assembly provided on the outer periphery of the middle part of the column.

[0009] Furthermore, the outer periphery of the column is uniformly and rollingly connected with balls at the upper and lower positions of the inner side of the sleeve, which reduces the frictional force of the sleeve rotating relative to the column and facilitates the rotation of the sleeve.

[0010] Furthermore, hexagonal grooves are provided on the outer periphery of the upper and lower sides of the sleeve for driving the sleeve to rotate.

[0011] Furthermore, the sliding sleeve is located inside the sleeve, and the outer threaded protrusion extends outward to the outer side of the column. The threaded protrusion is threadedly connected to the internal thread on the inner side of the sleeve. Therefore, when the sleeve rotates, it can drive the sliding sleeve to move up and down.

[0012] Furthermore, the limiting groove is adapted to the plunger latch.

[0013] Furthermore, the hydraulic cylinder is filled with hydraulic oil, and the plunger buckle is located at one end inside the hydraulic cylinder and is in contact with the hydraulic oil inside the hydraulic cylinder, so that the plunger buckle can be squeezed by the hydraulic oil.

[0014] Furthermore, the series assembly includes a mounting plate, which is fixedly connected to the periphery of the middle part of the column. A turntable is evenly and rotatably connected to the periphery of the mounting plate. Circular notches are provided on the upper and lower sides of the top and bottom turntables of the mounting plate. A through hole is provided on the turntable at the circular notch for the installation of the connecting rod.

[0015] Furthermore, the outer periphery of the turntable extends outward to the outer side of the mounting plate, and the outer periphery of the turntable is provided with teeth to facilitate driving the turntable to rotate from the outside of the mounting plate.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model, through the cooperation of the piston rod and the hydraulic cylinder with the plunger buckle and the limiting groove, and the ability to drive the sliding sleeve to move up and down when the sleeve rotates, can directly achieve support by pulling the hydraulic cylinder. It is easy to operate, improves the efficiency of building support frame construction, and after the support is completed, it can also be further extended and compacted to avoid loosening and improve the stability of the support.

[0018] 2. This utility model, through the design of the series components, allows for adjustment of the position and angle of the mounting holes, which facilitates the installation of the mounting plate and the connecting rod, thereby enabling the series connection of building support frames through the connecting rods and improving the convenience of the series connection installation of the connecting rods.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] A preferred embodiment of the present invention, a building support frame with a self-locking buckle, will be described in detail below, such as... Figures 1-6 As shown, a building support frame with a self-locking buckle includes a column 1, a base 2 fixedly installed at the bottom end of the column 1, a sleeve 3 rotatably connected to the outer periphery of the top of the column 1, and ball bearings uniformly limited and rolled at the upper and lower positions of the outer periphery of the column 1 inside the sleeve 3, which are used to reduce the frictional force of the sleeve 3 relative to the column 1 during rotation, and facilitate the rotation of the sleeve 3.

[0030] Hexagonal grooves 31 are provided on the outer periphery of the upper and lower sides of the sleeve 3 for driving the sleeve 3 to rotate.

[0031] The inner side of the sleeve 3 is provided with an internal thread 4. The inner side of the top of the column 1 is slidably connected with a sliding sleeve 5. The outer periphery of the sliding sleeve 5 is uniformly fixedly connected with threaded protrusions 6. The sliding sleeve 5 is located inside the sleeve 3, and the outer threaded protrusions 6 extend outward to the outer side of the column 1. The threaded protrusions 6 and the internal thread 4 on the inner side of the sleeve 3 are threadedly connected. Therefore, when the sleeve 3 rotates, it can drive the sliding sleeve 5 to move up and down.

[0032] The inner side of the sliding sleeve 5 is evenly provided with limiting grooves 7. A hydraulic cylinder 8 is inserted into the inner side of the sliding sleeve 5. A plunger buckle 9 is evenly and slidably connected to the outer periphery of the middle part of the hydraulic cylinder 8. The limiting grooves 7 and the plunger buckle 9 are adapted to each other. The hydraulic cylinder 8 is filled with hydraulic oil. One end of the plunger buckle 9 is located inside the hydraulic cylinder 8 and is in contact with the hydraulic oil inside the hydraulic cylinder 8, so that the plunger buckle 9 can be squeezed by the hydraulic oil.

[0033] The top of the hydraulic cylinder 8 is slidably connected to a piston rod 10, and a support seat 11 is fixedly installed at the top of the piston rod 10.

[0034] Furthermore, such as Figure 1 , Figures 7-8 As shown, a series assembly 12 is provided on the periphery of the middle part of the column 1. The series assembly 12 includes a mounting plate 121. The mounting plate 121 is fixedly connected to the periphery of the middle part of the column 1. A turntable 122 is uniformly and rotatably connected to the periphery of the mounting plate 121. The periphery of the turntable 122 extends outward to the outside of the mounting plate 121, and the periphery of the turntable 122 is provided with teeth to facilitate the rotation of the turntable 122 from the outside of the mounting plate 121.

[0035] The top and bottom of the mounting plate 121 and the bottom turntable 122 have circular notches 123 on the upper and lower sides. The turntable 122 has a through hole 124 at the circular notch 123 for mounting the connecting rod.

[0036] The working principle of this utility model is as follows:

[0037] When in use, since the top of the support seat 11 is not squeezed, the piston rod 10 will not be driven to squeeze the hydraulic oil inside the hydraulic cylinder 8, so that the plunger buckle 9 can retract elastically, and the hydraulic cylinder 8 can be directly pulled to extend its length.

[0038] When the hydraulic cylinder 8 drives the support seat 11 to contact the supported component, the support seat 11 will drive the piston rod 10 to compress the hydraulic oil inside the hydraulic cylinder 8 under the action of the reaction force until the bottom end of the support seat 11 contacts the top end face of the hydraulic cylinder 8. At the same time, it will pressurize the hydraulic oil inside the hydraulic cylinder 8, causing the plunger buckle 9 to extend outward and engage with the limiting groove 7 on the inner side of the sliding sleeve 5, thereby completing the support.

[0039] After the support is completed, the sleeve 3 can be driven to rotate through the hexagonal grooves 31 on the upper and lower sides of the sleeve 3. During the rotation of the sleeve 3, the internal thread 4 on the inner side of the sleeve 3 is connected to the threaded protrusion 6 on the outer side of the sliding sleeve 5. The sliding sleeve 5 is limited and slidably connected inside the column 1, which can drive the sliding sleeve 5 to move upward, thereby driving the hydraulic cylinder 8 to move further upward, so that the support seat 11 can further compact the supported component and improve the stability of the support for the supported component.

[0040] After the building support frame is installed, the connecting rods between the building support frames can be installed using the design of the series assembly 12. During the installation process, the turntable 122 can be driven to rotate to adjust the position and angle of the waist hole 124 on the turntable 122. This allows the mounting plate 121 to be installed with the connecting rod at the circular notch 123 using the waist hole 124 on the turntable 122, thereby realizing the series connection between the building support frames through the connecting rods.

[0041] When the building support frame needs to be dismantled, the sleeve 3 can be rotated in the reverse direction, which will cause the sliding sleeve 5 to move downward and drive the hydraulic cylinder 8 to move downward until the support seat 11 at the top of the piston rod 10 is separated from the supported component. Then the hydraulic cylinder 8 is depressurized again, so that the plunger buckle 9 can retract elastically, and the hydraulic cylinder 8 can be moved down and retracted into the column 1 again for easy use next time.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
