Description

Technical Field

[0001] This utility model relates to the field of support equipment, specifically to a multi-directionally adjustable support frame. Background Technology

[0002] In fields such as machinery manufacturing, automobile repair, and construction engineering, support jigs are often used to fix and support workpieces or other support structures to facilitate subsequent processing or operations. In construction engineering, they can support precast concrete components and steel structural parts, aiding in on-site assembly and installation, and can also assist in fixing scaffolding and other support structures, improving construction safety.

[0003] Chinese patent CN216830827U discloses an adjustable support frame for steel wall panels, comprising two bases, two columns, four brackets, a first crossbeam, and a second crossbeam. The two bases are respectively vertically fixed to both ends of the first crossbeam, and one end of each column is vertically fixed to a base. The distance between the joint between the column and the base is the same as the distance between the joint between the first crossbeam and the base and one end of the base. The columns are perpendicular to the first crossbeam, and brackets are provided on both sides of each column. Each column has a number of pin holes of corresponding height arranged in a vertical line. The two ends of the second crossbeam are respectively inserted into the corresponding pin holes of the two columns. A rubber sleeve is fitted on the outside of the first crossbeam.

[0004] The frame can only be adjusted vertically by inserting pin holes of different heights into the second crossbeam, and cannot be adjusted horizontally. In particular, when supporting the structure to be supported and the main building structure, it is often necessary to adjust the angle of the support equipment in advance, which makes it difficult to ensure the subsequent support of the structure to be supported and the main building structure.

[0005] Therefore, there is an urgent need to design a multi-directional adjustable support frame to address the shortcomings of existing technologies. Utility Model Content

[0006] The purpose of this invention is to provide a multi-directionally adjustable support frame to solve the problem of complex angle adjustment in the prior art.

[0007] The purpose of this utility model is achieved as follows: This utility model provides a multi-directional adjustable support frame, including a base plate, and a plurality of support legs are connected to the bottom surface of the base plate; The bottom plate is provided with a vertical cylinder at the top, and a rotating cylinder is rotatably connected inside the vertical cylinder. The upper end of the rotating cylinder extends out of the vertical cylinder and is connected to the top plate. The vertical cylinder is equipped with a support spring to assist in supporting the rotating cylinder, and the bottom surface of the top plate is inserted into the top surface of the vertical cylinder.

[0008] As a preferred embodiment, the support leg is rotatably connected to the bottom surface of the base plate, and the bottom surface of the base plate is provided with side plates at both ends to support the support leg, and the side plates are integrally formed with the base plate.

[0009] As a preferred embodiment, the base plate is made of iron, and the support leg is provided with a magnetic adsorption component corresponding to the base plate for magnetic adsorption with the base plate.

[0010] As a preferred embodiment, a threaded rod corresponding to the support leg is rotatably connected to the side plate, and the threaded rod is provided with an axially extending strip groove, and the strip groove is provided with scale markings.

[0011] As a preferred embodiment, the top surface of the top plate is provided with multiple insertion holes, which are evenly distributed circumferentially with the axis of the rotating cylinder as a reference, and the top of the vertical cylinder is provided with a plug corresponding to the insertion holes.

[0012] As a preferred embodiment, the insert has a frustum-shaped structure, and its large end is fixedly connected to the top of the vertical cylinder.

[0013] As a preferred embodiment, the upper part of the vertical cylinder has a frustum-shaped structure, with the larger end of the frustum-shaped structure extending toward the top plate.

[0014] Positive and beneficial effects: The support legs and the base plate work together to form a stable multi-point support, which provides stable support for the entire device. When the top plate is not under the load of the workpiece, the support spring can push the rotating cylinder upward with its own elastic force and lift the top plate upward, so that the insertion fit between the bottom surface of the top plate and the top surface of the vertical cylinder is automatically disengaged, so that the operator can directly and easily push the top plate to rotate horizontally without manually lifting the top plate to release the positioning, which greatly reduces the difficulty of angle adjustment. When the top plate is under pressure, the pressure is transmitted to the rotating cylinder through the top plate and overcomes the elastic force of the support spring, causing the spring to compress. The rotating cylinder then moves down, causing the bottom surface of the top plate to be inserted and fixed to the top surface of the vertical cylinder. This directly restricts the rotational freedom of the rotating cylinder, effectively preventing the top plate from rotating arbitrarily during the load-bearing process, ensuring the stability of the workpiece position, and meeting the accuracy requirements of subsequent processing, inspection and other scenarios. The support springs, through an elastic adaptation of "pressureless push-up for positioning and pressure compression for fixing," connect the entire process of top plate angle adjustment and positioning locking, which not only improves the convenience of adjustment but also ensures load-bearing stability.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] First Embodiment

[0018] See Figures 1-4 As shown, this utility model provides a multi-directional adjustable support frame, including a base plate 1. Multiple support legs 2 are connected to the bottom surface of the base plate 1. The number of support legs 2 is 3-4, and they are evenly distributed along the circumference of the bottom surface of the base plate 1, or in a rectangular distribution when there are four support legs 2. The base plate 1 is made of Q235 iron plate with a thickness of 6-10mm and the surface is galvanized for rust prevention. A vertical cylinder 3 is provided at the top of the base plate 1. The vertical cylinder 3 is a seamless steel pipe with a thickness of 5-8mm, and is fixed to the middle position of the base plate 1 by welding. The weld height is not less than 5mm. A rotating cylinder 401 is rotatably connected inside the vertical cylinder 3. 1. The outer diameter of the rotating cylinder 401 is adapted to the inner diameter of the vertical cylinder 3, with the fitting clearance controlled at 0.08-0.15mm. The upper end of the rotating cylinder 401 extends out of the vertical cylinder 3 and is connected to a top plate 4. Specifically, the top plate 4 is a steel plate with a thickness of 8-12mm, which is detachably connected to the top of the rotating cylinder 401 by multiple bolts. The bottom of the rotating cylinder 401 is provided with an open cavity. Inside the vertical cylinder 3, there is a support spring 5 to assist the rotating cylinder 401. The support spring 5 is a cylindrical helical compression spring made of 50CrVA, with a spring wire diameter of 2.5-3.5mm, a free height of 32-38mm, and a working load of 1200-2000N. In this way, under the conditions of a top plate of 10kg and a jig weight of more than 20kg, the support spring 5 is precisely matched with the "push-up to unposition and compression to assist in fixing" function, ensuring that the top plate can be lifted more than 3mm to disengage from the plug-in lock when there is no pressure. In addition, the selection of support spring 5 is reserved with a safety margin of about 12.5%, which takes into account the load-bearing stability and the service life of the spring, and avoids the load from exceeding the original parameter range due to the increase in weight.

[0019] The bottom of the rotating cylinder 401 is provided with an open mouth, and the bottom surface of the top plate 4 is inserted and matched with the top surface of the vertical cylinder 3.

[0020] In the above structure, the device is placed stably on the target site, and supported by multiple support legs 2 on the bottom surface of the base plate 1, depending on the flatness of the ground and the load-bearing requirements. If the angle of the top plate 4 needs to be adjusted in advance, since the top plate 4 is not under force at this time, the support spring 5 inside the vertical cylinder 3 will push the rotating cylinder 401 upward with its elastic force, causing the top plate 4 to rise, so that the insertion and mating block and the insertion hole of the bottom surface of the top plate 4 and the top surface of the vertical cylinder 3 will automatically disengage; the operator can directly push the top plate 4, causing the rotating cylinder 401 to rotate inside the vertical cylinder 3, and adjust the top plate 4 to the approximate target angle; The workpiece to be supported is placed stably on the top plate 4. The weight of the workpiece is transmitted to the rotating cylinder 401 through the top plate 4 and overcomes the elastic force of the support spring 5, causing the rotating cylinder 401 to drive the top plate 4 to move down until the bottom surface of the top plate 4 is in contact with the top surface of the vertical cylinder 3. The insert block at the top of the vertical cylinder 3 is inserted into the corresponding insertion hole on the bottom surface of the top plate 4 to complete the positioning of the top plate 4 and prevent the top plate 4 from rotating arbitrarily after the workpiece is placed. If the angle needs to be finely adjusted after the workpiece is placed, the operator can slightly lift the top plate 4 upwards. At this time, the elastic force of the support spring 5 can also be used to disengage the top plate 4 from the vertical cylinder 3. Then, push the top plate 4 to drive the rotating cylinder 401 to rotate. After adjusting to the required angle, release the top plate 4. The top plate 4 moves down under its own weight and the weight of the workpiece, and the positioning is completed again through the insertion and engagement.

[0021] The second embodiment differs from the first embodiment in that: Support leg 2 is rotatably connected to the bottom surface of base plate 1 and rotates via a rotating shaft. The rotation angle range is 0-160°. Support leg 2 is made of seamless steel pipe with an outer diameter of 25-40mm and a wall thickness of 4-6mm. The bottom surface of base plate 1 has side plates at both ends that support support leg 2. The side plates are 15-25mm high, made of the same material as base plate 1 and integrally formed. The rotation angle of support leg 2 can be limited by the side plates. That is, after the support leg 3 is rotated, the outer end of support leg 3 abuts against the side plates to form a rigid and stable support. The base plate 1 is made of iron. The support leg 2 is equipped with a magnetic adsorption component 201 corresponding to the base plate 1. The magnetic adsorption component 201 is a magnet with a size of 15×10×5mm and an adsorption force of not less than 200N. It is used to magnetically adsorb with the base plate 1. After the support leg 2 rotates towards the base plate 1, it can magnetically adsorb with the base plate 1 using the magnetic adsorption component 201 to realize the storage setting of the support leg 2.

[0022] A threaded rod corresponding to support leg 2 is rotatably connected to the side plate. The threaded rod has a diameter of 6-10mm, a length of 60-100mm, and a thread specification of M6-M10. A hexagonal knob is provided at the outer end of the threaded rod for easy adjustment. The threaded rod has an axially extending groove with a width of 4-6mm and a depth of 1.5-2.5mm. The groove has scale markings with a scale accuracy of 1mm and a range of 0-80mm, which can visually display the extension length of the threaded rod.

[0023] The third embodiment differs from the first embodiment in that: The top surface of the top plate 4 is provided with multiple insertion holes 402, the number of insertion holes 402 is 8-16, the diameter is 6-10mm, the depth is 8-25mm, the inner wall roughness Ra≤1.6μm, the insertion holes 402 are evenly distributed in a circle around the axis of the rotating cylinder 401, and the central angle between adjacent insertion holes 402 is 22.5°-45°. The top of the vertical cylinder 3 is provided with a plug block 301 corresponding to the insertion hole 402, and the height of the plug block 301 is adapted to the depth of the insertion hole 402. The insert 301 has a frustoconical structure, and its large end is fixedly connected to the top of the vertical cylinder 3. The insert 301 is made of 45 steel and its surface is hardened. The hardness is HRC35-40. The diameter of the large end is the same as the diameter of the insertion hole 402, the diameter of the small end is 4-8mm, and the taper is 1:5-1:8. When the top plate 4 is not under workpiece load, i.e., in a stress-free state, the support spring 5 pushes the rotating cylinder 401 upward with its own elastic force, causing the top plate 4 to rise synchronously. This causes the insertion block 301 of the insertion structure between the bottom surface of the top plate 4 and the top surface of the vertical cylinder 3 to automatically disengage from the insertion hole 402. At this time, the rotating cylinder 401 has no positioning constraint, and the operator can easily push the top plate 4 to rotate and adjust the angle without manually lifting the top plate, reducing the difficulty of operation. When the top plate 4 is under pressure, either by placing a workpiece or by manually pressing it down, the pressure is transmitted through the top plate 4 to the rotating cylinder 401. This pressure overcomes the elastic force of the supporting spring 5, causing the spring to compress. The rotating cylinder 401 then moves downward, causing the bottom surface of the top plate 4 to fit against the top surface of the vertical cylinder 3. At this time, the insert block 301 at the top of the vertical cylinder 3 is precisely inserted into the insertion hole 402 of the top plate 4, forming a fixed insertion connection. This directly restricts the rotational freedom of the rotating cylinder 401, effectively preventing the top plate 4 from rotating arbitrarily during the load-bearing process, ensuring the stability of the workpiece position, and meeting the accuracy requirements of subsequent processing, inspection, and other scenarios. The support spring 5, through its elastic adaptation of "pressureless push-up for positioning - pressure compression for fixing", connects the entire process of top plate angle adjustment and positioning locking, which not only improves the convenience of adjustment but also ensures load-bearing stability. It is a key component for realizing the dual functions of "adjustable + stable fixation" of the jig frame.

[0024] The upper part of the vertical cylinder 3 has a frustum-shaped structure. The large end of the frustum-shaped structure extends toward the top plate 4, and the diameter of its small end is the same as the outer diameter of the vertical cylinder 3. The material is the same as the vertical cylinder 3 and it is integrally formed with the vertical cylinder 3. The height is 20-30mm. The diameter of the large end of the frustum-shaped structure is 10-15mm larger than the outer diameter of the vertical cylinder 3, so as to better support the top plate 4. The insert block 301 is set at the large end of the frustum-shaped structure.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
