Description

Technical Field

[0001] This utility model relates to the field of support technology, and in particular to an adjustable and balanced support. Background Technology

[0002] X-shaped shelves and cross-shaped supports, as common support structures, are widely used in pet food racks, display racks, tool racks, decorative racks, and many other fields due to their simple design and certain load-bearing capacity. However, existing X-shaped shelves and cross-shaped supports have many problems in practical use.

[0003] Traditional X-frames and crosses typically have long crossbeams, making them prone to deformation under external forces. This is especially true at the intersections of the crossbeams, where bolts are commonly used for fixing. While this fastening structure achieves connection at the intersections and ensures structural integrity, it negatively impacts the stability of the crossbeam ends. The middle of the crossbeam is subjected to bolt tightening force, but the ends lack sufficient support and restraint, making the crossbeam susceptible to deformation. This causes the ends to warp, ultimately leading to an imbalance in the entire support structure, manifesting as unevenness and swaying. These problems not only affect the normal function of the X-frame and cross, reducing their load-bearing capacity and stability, but may also damage items placed on them and even pose safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable balance support.

[0005] The technical solution to achieve the purpose of this utility model is: an adjustable balance bracket, including a first crossbeam, a second crossbeam, bolts and a compression spring. The first crossbeam has first support feet at both ends, and the second crossbeam has second support feet at both ends. The first crossbeam is located above the second crossbeam and intersects with the second crossbeam. A first hole is vertically opened at the intersection of the first crossbeam and the second crossbeam, and a second hole is vertically opened at the intersection of the second crossbeam and the first crossbeam. The bolt passes through the first hole and the second hole, and the first crossbeam and the second crossbeam are fastened by the bolt. The compression spring is located between the first crossbeam and the second crossbeam, with one end of the compression spring contacting the first crossbeam and the other end contacting the second crossbeam.

[0006] Furthermore, the first crossbeam and the second crossbeam are X-shaped or cross-shaped.

[0007] Furthermore, a first channel is formed on the bottom surface of the intersection of the first and second crossbeams, and the second crossbeam is secured within the first channel. Once the second crossbeam is secured in the first channel, the first channel limits the movement of the second crossbeam, preventing it from moving in any direction except along its length. This design makes the connection between the first and second crossbeams more stable and reliable, especially after the bolt connection, as the first channel prevents rotational movement between the first and second crossbeams. Additionally, the first channel reduces the total thickness and height difference between the first and second crossbeams, resulting in better overall flatness of the support structure.

[0008] Furthermore, a second channel is formed on the top surface of the intersection of the second crossbeam and the first crossbeam, and the first crossbeam is secured within the second channel. After the first crossbeam is secured within the second channel, the second channel limits the movement of the first crossbeam, ensuring that the second crossbeam cannot move in any direction except along its length. This design makes the connection between the first and second crossbeams more stable and reliable, especially after the bolt connection, as the second channel prevents rotational movement between the first and second crossbeams. Additionally, with the second channel, the total thickness and height difference between the first and second crossbeams are smaller, resulting in better overall flatness of the support structure.

[0009] Furthermore, a limiting groove for the upper end of the compression spring is provided on the bottom surface of the intersection of the first and second crossbeams, and the upper end of the compression spring is located within the limiting groove. When a first channel is provided on the bottom surface of the intersection of the first and second crossbeams, the limiting groove for the upper end of the compression spring is located on the bottom of the first channel. The limiting groove for the upper end of the compression spring serves two purposes: firstly, it limits the upper end of the compression spring, preventing it from shifting and making the installation of the compression spring more reliable; secondly, it guides the extension and contraction of the compression spring, preventing it from bending during extension and contraction, making the deformation of the compression spring more reliable.

[0010] Furthermore, a lower end limiting groove for the compression spring is provided on the top surface of the intersection of the second crossbeam and the first crossbeam, and the lower end of the compression spring is located within the lower end limiting groove. When a second channel is provided on the top surface of the intersection of the second crossbeam and the first crossbeam, the lower end limiting groove for the compression spring is located on the bottom of the second channel. The setting of the lower end limiting groove for the compression spring serves two purposes: firstly, it limits the lower end of the compression spring, preventing it from shifting and making the installation of the compression spring more reliable; secondly, it guides the extension and contraction of the compression spring, preventing it from bending during extension and contraction, making the deformation of the compression spring more reliable.

[0011] Furthermore, the compression spring is sleeved on the bolt. With this configuration, on the one hand, the compression spring is coaxial with the bolt, and the compression spring is located at the center of the first and second crossbeams, at the intersection of the first and second crossbeams. This ensures that the force exerted on the first or second crossbeam by the compression spring is more even, preventing tilting due to uneven force. On the other hand, the bolt guides the extension and retraction of the compression spring, preventing it from bending during extension and retraction, making the spring's deformation more reliable.

[0012] Furthermore, the bolt is provided with a limiting member, and a fastener has a threaded hole. The bolt passes through the threaded hole and is threadedly engaged with the fastener. One of the limiting member and the fastener is in contact with the top surface of the first crossbeam, and the other is in contact with the bottom surface of the second crossbeam. To loosen or tighten the bolt, the fastener is rotated relative to the bolt. The fastening structure for the first and second crossbeams can be as follows: the first hole is a through hole, and the second hole is a threaded hole. The bolt passes through the first hole and engages with the threaded part of the second hole to fix and install the first and second crossbeams. Alternatively, the second hole is a through hole, and the first hole is a threaded hole. The bolt passes through the second hole and engages with the threaded part of the first hole to fix and install the first and second crossbeams. Another option is that both the first and second holes are through holes. After the bolt passes through both holes, the fastener is threaded onto the bolt, and the fastener and the limiting member are tightly fitted to the first and second crossbeams respectively to fix and install them. Compared to the former, the latter method eliminates the need for threaded holes in the first or second crossbeams when clamped by the fastener, making it particularly convenient for wooden structures where threaded holes are difficult to create.

[0013] Furthermore, the limiting member is the nut of the bolt. The limiting member can be the nut of the bolt, a piece fitted onto the bolt, or a block fixed to the bolt. Compared to other components, the bolt typically has a nut, making it more readily available.

[0014] Furthermore, the threaded hole of the fastener is open at one end and closed at the other. The fastener can be a nut or the structure described above. Compared to a nut structure, when the threaded hole of the fastener is open at one end and closed at the other, the fastener can be made into a handle structure. When the bolt is loosened or tightened to adjust the stability of the first support leg of the first crossbeam and the second support leg of the second crossbeam, the handle structure is more conducive to the rotation operation of the fastener.

[0015] Furthermore, the limiting member contacts the bottom surface of the second crossbeam, and the fastener contacts the top surface of the first crossbeam. The fastener is located above the bracket for easier operation.

[0016] This utility model relates to an adjustable balance bracket. By placing a compression spring between the first and second crossbeams, the force of the spring ensures that the first and second crossbeams are always securely fastened to the bolts. While ensuring a stable connection, the deformable nature of the compression spring also allows for adjustment of the tightness of the connection between the first and second crossbeams. When the first and second crossbeams deform due to the connection stress, causing unevenness or wobbling of the first and second support legs, the bolts can be rotated to loosen the fastening structure. This reduces the stress on the first and second crossbeams, preventing further deformation. Consequently, the ends of the first and second crossbeams no longer warp due to deformation, thus achieving leveling of the bracket.

[0017] This utility model features an adjustable balance bracket, which offers high flexibility in use. Its stability can be adjusted according to the usage conditions, improving the bracket's stability and load-bearing capacity, and preventing damage to items on it due to shaking.

[0021] The preferred embodiment of the adjustable balance bracket of this utility model will be described in detail below with reference to the accompanying drawings:

[0022] like Figures 1 to 3 As shown, an adjustable balance bracket includes a first crossbeam 1, a second crossbeam 2, a bolt 3, and a compression spring 4. The first crossbeam 1 has first support feet 10 at both ends, and the second crossbeam 2 has second support feet 20 at both ends. The first crossbeam 1 is located above the second crossbeam 2 and is intersected with the second crossbeam 2. A first hole 11 is vertically opened at the intersection of the first crossbeam 1 and the second crossbeam 2, and a second hole 21 is vertically opened at the intersection of the second crossbeam 2 and the first crossbeam 1. The bolt 3 passes through the first hole 11 and the second hole 21, and the first crossbeam 1 and the second crossbeam 2 are fastened by the bolt 3. The compression spring 4 is located between the first crossbeam 1 and the second crossbeam 2, with one end of the compression spring 4 contacting the first crossbeam 1 and the other end contacting the second crossbeam 2.

[0023] This utility model relates to an adjustable balance support, comprising a first crossbeam 1 with first support legs 10 at both ends and a second crossbeam 2 with second support legs 20 at both ends. The first crossbeam 1 and the first support legs 10 at both ends are inverted U-shapes, as are the second crossbeam 2 and the second support legs 20 at both ends. The first crossbeam 1 and the second crossbeam 2 are fastened and connected by bolts 3 at their intersections, and the bottom surfaces of the first support legs 10 and the second support legs 20 are on the same horizontal plane. The bolt 3 connection structure includes a compression spring 4, which is vertically positioned. The upper end of the compression spring 4 contacts the first crossbeam 1, and the lower end contacts the second crossbeam 2. The compression spring 4, compressed between the first crossbeam 1 and the second crossbeam 2, applies an outward force to the first crossbeam 1 and the second crossbeam 2, ensuring that the bolt 3 connection structure remains securely fastened to the bolt 3 regardless of whether it is loose or tight. Furthermore, the deformability of the compression spring 4 provides the bolt 3 connection structure with the ability to be loosened or tightened.

[0024] This utility model relates to an adjustable balance bracket. A first crossbeam 1 with first support feet 10 at both ends and a second crossbeam 2 with second support feet 20 at both ends are connected by bolts 3. During use, the first crossbeam 1 and the second crossbeam 2 deform, causing the first support feet 10 and the second support feet 20 to become uneven and wobble. To stabilize the bracket, the bolts 3 are rotated, loosening their fastening mechanism. After the bolts 3 loosen, the compression spring 4 recovers its deformation and lengthens. The compression spring 4 presses against the first crossbeam 1 and the second crossbeam 2, keeping them still fastened to the bolts 3. However, due to the loosening of the fastening mechanism, the force exerted by the bolts 3 on the first crossbeam 1 and the second crossbeam 2 decreases, reducing their deformation. The first support feet 10 at both ends of the first crossbeam 1 no longer tilt upwards, and the second support feet 20 at both ends of the second crossbeam 2 no longer tilt downwards, thus leveling the bracket.

[0025] This utility model relates to an adjustable balance bracket. By placing a compression spring 4 between the first crossbeam 1 and the second crossbeam 2, the force of the compression spring 4 ensures that the first crossbeam 1 and the second crossbeam 2 are always tightly secured to the bolt 3. While ensuring a stable connection, the deformable nature of the compression spring 4 also provides adjustable tightness for the connection between the first crossbeam 1 and the second crossbeam 2. When the first crossbeam 1 and the second crossbeam 2 deform due to the connection force, causing unevenness or wobbling of the first support leg 10 and the second support leg 20, the bolt 3 can be rotated to loosen its fastening structure. This reduces the force on the first crossbeam 1 and the second crossbeam 2, preventing further deformation. The ends of the first crossbeam 1 and the second crossbeam 2 also no longer warp due to deformation, thus achieving leveling of the bracket.

[0026] This utility model features an adjustable balance bracket, which offers high flexibility in use. Its stability can be adjusted according to the usage conditions, improving the bracket's stability and load-bearing capacity, and preventing damage to items on it due to shaking.

[0027] The adjustable balance bracket of this utility model preferably has the first crossbeam 1 and the second crossbeam 2 in an X-shape or a cross shape.

[0028] In this adjustable balance bracket, preferably, a first groove 12 is formed on the bottom surface of the intersection of the first crossbeam 1 and the second crossbeam 2, and the second crossbeam 2 is engaged within the first groove 12. After the second crossbeam 2 is engaged within the first groove 12, the first groove 12 limits the movement of the second crossbeam 2, ensuring that the first crossbeam 1 cannot move in any direction except along the length of the second crossbeam 2. This arrangement makes the connection between the first crossbeam 1 and the second crossbeam 2 more stable and reliable. In particular, after being connected by the bolts 3, the first crossbeam 1 and the second crossbeam 2 will not rotate or move under the constraint of the first groove 12. In addition, after setting the first groove 12, the total thickness of the first crossbeam 1 and the second crossbeam 2, as well as the height difference between the first crossbeam 1 and the second crossbeam 2, are smaller, resulting in better overall flatness of the bracket.

[0029] In this adjustable balance bracket, preferably, a second groove 22 is formed on the top surface of the intersection of the second crossbeam 2 and the first crossbeam 1, and the first crossbeam 1 is locked within the second groove 22. After the first crossbeam 1 is locked within the second groove 22, the second groove 22 limits the first crossbeam 1, so that the second crossbeam 2 cannot move in any direction except along the length direction of the first crossbeam 1. This arrangement makes the connection between the first crossbeam 1 and the second crossbeam 2 more stable and reliable. In particular, after being connected by the bolts 3, the first crossbeam 1 and the second crossbeam 2 will not rotate or move under the limitation of the second groove 22. In addition, after setting the second groove 22, the total thickness of the first crossbeam 1 and the second crossbeam 2, as well as the height difference between the first crossbeam 1 and the second crossbeam 2, are smaller, and the overall flatness of the bracket is relatively better.

[0030] This utility model relates to an adjustable balance support. A first channel 12 is formed on the bottom surface of the intersection of the first crossbeam 1 and the second crossbeam 2, and a second channel 22 is formed on the top surface of the intersection of the second crossbeam 2 and the first crossbeam 1. The first channel 12 and the second channel 22 are opposite each other. With both channels 12 and 22 present, the first channel 12 limits the second crossbeam 2, and the second channel 22 limits the first crossbeam 1. The first crossbeam 1 and the second crossbeam 2 cannot move horizontally or rotate, resulting in good connection stability. The total thickness and height difference between the first crossbeam 1 and the second crossbeam 2 are small, leading to higher overall flatness of the support. In addition, the first channel 12 and the second channel 22 also serve a positioning function. When assembling the first crossbeam 1 and the second crossbeam 2, it is only necessary to align the first channel 12 and the second channel 22 to achieve quick assembly, avoiding the need to align the first hole 11 and the second hole 21 when installing the bolt 3.

[0031] In this adjustable balance bracket, preferably, a spring upper end limiting groove 13 is further formed on the bottom surface of the intersection of the first crossbeam 1 and the second crossbeam 2, and the upper end of the spring 4 is located within the spring upper end limiting groove 13. When a first groove 12 is formed on the bottom surface of the intersection of the first crossbeam 1 and the second crossbeam 2, the spring upper end limiting groove 13 is located on the bottom of the first groove 12. The setting of the spring upper end limiting groove 13 serves two purposes: firstly, it limits the upper end of the spring 4, preventing it from shifting and making the installation of the spring 4 more reliable; secondly, it guides the extension and retraction of the spring 4, preventing it from bending during extension and retraction, making the deformation of the spring 4 more reliable.

[0032] In this adjustable balance bracket, preferably, a lower end limiting groove 23 for the compression spring is provided on the top surface of the intersection of the second crossbeam 2 and the first crossbeam 1, and the lower end of the compression spring 4 is located within the lower end limiting groove 23. When a second channel 22 is provided on the top surface of the intersection of the second crossbeam 2 and the first crossbeam 1, the lower end limiting groove 23 for the compression spring is located on the bottom of the second channel 22. The provision of the lower end limiting groove 23 for the compression spring serves two purposes: firstly, it limits the lower end of the compression spring 4, preventing it from shifting and making the installation of the compression spring 4 more reliable; secondly, it guides the extension and retraction of the compression spring 4, preventing it from bending during extension and retraction, making the deformation of the compression spring 4 more reliable.

[0033] In this adjustable balance bracket, preferably, the compression spring 4 is fitted onto the bolt 3. With this configuration, on the one hand, the compression spring 4 is coaxial with the bolt 3, and the compression spring 4 is located at the center of the first crossbeam 1 and the second crossbeam 2, at the intersection of the first crossbeam 1 and the second crossbeam 2. This ensures that the force exerted on the first crossbeam 1 or the second crossbeam 2 by the compression spring 4 is more even, preventing tilting due to uneven force. On the other hand, the bolt 3 guides the extension and retraction of the compression spring 4, preventing it from bending during extension and retraction, making the deformation of the compression spring 4 more reliable.

[0034] In this utility model of an adjustable balance bracket, preferably, the bolt 3 is provided with a limiting member 31, and a fastener 32 is provided with a threaded hole 321. The bolt 3 passes through the threaded hole 321 and is threadedly engaged with the fastener 32. One of the limiting member 31 and the fastener 32 is in contact with the top surface of the first crossbeam 1, and the other is in contact with the bottom surface of the second crossbeam 2. To loosen or tighten the bolt 3, the fastener 32 is rotated relative to the bolt 3. The fastening structure of the first crossbeam 1 and the second crossbeam 2 can be as follows: the first hole 11 is a through hole, the second hole 21 is a threaded hole, and the bolt 3 passes through the first hole 11 and engages with the threaded part of the second hole 21 to fix and install the first crossbeam 1 and the second crossbeam 2; or the second hole 21 is a through hole, the first hole 11 is a threaded hole, and the bolt 3 passes through the second hole 21 and engages with the threaded part of the first hole 11 to fix and install the first crossbeam 1 and the second crossbeam 2; or both the first hole 11 and the second hole 21 are through holes, and after the bolt 3 passes through the first hole 11 and the second hole 21, the fastener 32 is threaded onto the bolt 3, and the first crossbeam 1 and the second crossbeam 2 are fixed and installed by the tight contact of the fastener 32 and the limiting member 31 with the first crossbeam 1 and the second crossbeam 2 respectively. Compared to the former, the latter does not require threaded holes to be made on the first crossbeam 1 or the second crossbeam 2 when clamped by the fastener 32, which is more convenient, especially for wooden structures where it is difficult to make threaded holes.

[0035] In this utility model of an adjustable balance bracket, preferably, the limiting member 31 is the nut of the bolt 3. The limiting member 31 can be the nut of the bolt 3, a piece fitted onto the bolt 3, or a block fixed to the bolt 3. Compared to other types, the bolt 3 usually has a nut, making it more readily available.

[0036] In this adjustable balance bracket, preferably, the threaded hole 321 of the fastener 32 is open at one end and closed at the other. The fastener 32 can be a nut or the structure described above. Compared to a nut structure, when the threaded hole 321 of the fastener 32 is open at one end and closed at the other, the fastener 32 can be made into a handle structure. When the bolt 3 is loosened or tightened to adjust the stability of the first support leg 10 of the first crossbeam 1 and the second support leg 20 of the second crossbeam 2, the handle structure is more conducive to the rotation operation of the fastener 32.

[0037] The adjustable balance bracket of this utility model can be formed by directly opening the threaded hole 321 on the fastener 32, or by opening a channel 322 on the fastener 32, and embedding a nut cylinder structure in the channel 322.

[0038] In this adjustable balance bracket, the limiting member 31 is in contact with the bottom surface of the second crossbeam 2, and the fastener 32 is in contact with the top surface of the first crossbeam 1. The fastener 32 is located above the bracket for easier operation.

[0039] This utility model's adjustable balance bracket can be used, but is not limited to, as a pet food rack, display rack, tool rack, decorative rack, etc.

[0040] For those skilled in the art to which this utility model pertains, several simple deductions or substitutions can be made without departing from the concept of this utility model, and all such deductions or substitutions should be considered to fall within the protection scope of this utility model.
