Description

Technical Field

[0001] This application relates to the field of welding support technology, for example to a screw-type bidirectional adjustable planar support device. Background Technology

[0002] During the welding process, large thin-walled box-type welded structural components often experience inward shrinkage deformation of the top and bottom plates due to stress deformation, and the correction after deformation is quite difficult.

[0003] Currently, when dealing with the deformation of the box body, workers often use multiple support columns, placing each support column at the location where deformation may occur to support the upper and lower plates inside the box body. However, using support columns can only support a single point, and due to size limitations, the support effect is not ideal, failing to effectively suppress the deformation of the box body. Furthermore, the support work is labor-intensive, time-consuming, and extremely inconvenient.

[0004] Therefore, it is evident that improving the support effect and enhancing the ease of operation are technical problems that urgently need to be solved by those skilled in the art.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a screw-type bidirectional adjustable planar support device, which provides stable and reliable support, good protection against welding stress deformation, and has a simple structure, quick and flexible operation, thus improving the convenience of operation.

[0008] In some embodiments, a screw-type bidirectional adjustable planar support device includes: a lower support, an upper support, and an adjusting screw. One end of the adjusting screw is threadedly connected to the lower support, and the other end is threadedly connected to the upper support, wherein the threads at the two threaded connection positions have opposite directions of rotation. When the adjusting screw rotates, the lower support and the upper support at both ends move synchronously towards each other or away from each other along the axial direction of the adjusting screw.

[0009] Optionally, a mounting sleeve is provided in the middle of the adjusting screw, and an operating handle is connected to the mounting sleeve.

[0010] Optionally, the operating handle is movably and horizontally mounted on the assembly sleeve.

[0011] Optionally, the operating handle is threadedly connected to the sleeve of the device.

[0012] Optionally, one end of the adjusting screw is connected to the lower support via a first threaded sleeve, and the other end is connected to the upper support via a second threaded sleeve, wherein the thread in the first threaded sleeve is a right-hand thread, and the thread in the second threaded sleeve is a left-hand thread.

[0013] Optionally, the first threaded sleeve and the lower support, as well as the second threaded sleeve and the upper support, are all integrally formed structures.

[0014] Optionally, the centers of gravity of both the lower and upper supports are located on the axis of the adjusting screw.

[0015] Optionally, both the lower support and the upper support have a planar structure on the side away from the screw.

[0016] Optionally, the adjusting screw includes a right-hand threaded section, a telescopic section, and a left-hand threaded section. One end of the right-hand threaded section is connected to the lower support, one end of the telescopic section is connected to the other end of the right-hand threaded section, one end of the left-hand threaded section is connected to the other end of the telescopic section, and the other end of the left-hand threaded section is connected to the upper support.

[0017] Optionally, the upper support and the lower support have the same structure.

[0018] The screw-type bidirectional adjustable planar support device provided in this disclosure can achieve the following technical effects:

[0019] By rotating the adjusting screw, the lower and upper supports at both ends can move synchronously towards each other or away from each other along the axial direction of the adjusting screw. When the lower and upper supports move away from each other, the reverse movement of the lower and upper supports can support the interior of the box, thereby effectively preventing the inward shrinkage deformation of the top and bottom plates of the box caused by stress deformation during the welding process. The support is stable and reliable, and the anti-welding stress deformation effect is good. In addition, the device has a simple structure, is quick and flexible to operate, and improves the convenience of operation.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0038] Combination Figure 1-3 As shown in the figure, this disclosure provides a screw-type bidirectional adjustable planar support device, including: a lower support 100, an upper support 200, and an adjusting screw 300. One end of the adjusting screw 300 is threadedly connected to the lower support 100, and the other end is threadedly connected to the upper support 200. The threads at the two threaded connection positions have opposite directions of rotation. When the adjusting screw 300 rotates, the lower support 100 and the upper support 200 at both ends move synchronously towards each other or away from each other along the axial direction of the adjusting screw 300.

[0039] The screw-type bidirectional adjustable planar support device provided in this embodiment allows the lower support 100 and upper support 200 at both ends to move synchronously towards each other or away from each other along the axial direction of the adjusting screw 300 by rotating the adjusting screw 300. When the lower support 100 and upper support 200 move away from each other, the back-moving lower support 100 and upper support 200 can support the interior of the box, thereby effectively avoiding the inward shrinkage deformation of the top and bottom plates of the box caused by stress deformation during the welding process. The support is stable and reliable, and the anti-welding stress deformation effect is good. In addition, the device has a simple structure, is quick and flexible to operate, and improves the convenience of operation.

[0040] Optionally, both the lower support 100 and the upper support 200 are rectangular structures. This results in a neat structure that provides more stable support for the interior of the enclosure.

[0041] Optionally, a mounting sleeve 400 is provided in the middle of the adjusting screw 300, and an operating handle 500 is connected to the mounting sleeve 400. In this way, when the operating handle 500 is turned, the adjusting screw 300 rotates, thereby causing the lower support 100 and the upper support 200 to move synchronously in opposite directions or in opposite directions, making the operation more time-saving and labor-saving, improving the convenience of operation, and enhancing the user experience.

[0042] Optionally, the operating handle 500 is movably and horizontally mounted on the mounting sleeve 400. This allows for quick and easy operation of the adjusting screw 300 with minimal effort, saving time and labor. The flexible installation also facilitates the adjustment of the position of the operating handle 500, making it suitable for various user needs.

[0043] Optionally, a horizontal through hole is provided inside the mounting sleeve 400, and a limit block 306 is provided on the inner side wall of the through hole. A limit groove 307 is provided on the operating handle 500. When the operating handle 500 is inserted into the mounting sleeve 400, the limit groove 307 can be fitted into the limit block 306. This effectively prevents the operation from being affected by the rotation of the operating handle 500, improves the operating experience, and ensures the smoothness and stability of the rotation of the control adjusting screw 300.

[0044] Optionally, a locking element is movably provided on the sleeve 400 to restrict the movement of the operating handle 500. By using the locking element to restrict the movement of the operating handle 500, the assembly of the operating handle 500 is made more secure, preventing displacement or rotation, and facilitating more stable control of the operating handle 500 to drive the adjusting screw 300, thus improving operational stability.

[0045] Optionally, the locking element includes a locking rod and a locking hole. The locking rod has an L-shaped structure, with one end mounted on the assembly sleeve 400 via a rotating shaft. The locking hole is located on the operating handle 500. When the locking rod is rotated to the first position, the other end of the locking rod can be inserted into the locking hole. This effectively restricts the horizontal movement of the operating handle 500.

[0046] Optionally, the operating handle 500 is threadedly connected to the mounting sleeve 400. This facilitates user operation by adjusting the position of the operating handle 500 through rotation, ensures connection stability, provides stable control of the adjusting screw 300's rotation, and makes installation and disassembly convenient and quick.

[0047] In other embodiments, the mounting sleeve 400, operating handle 500, and adjusting screw 300 are integrally formed. This makes the structure more stable and improves operational stability.

[0048] Optionally, one end of the adjusting screw 300 is connected to the lower support 100 via a first threaded sleeve 301, and the other end is connected to the upper support 200 via a second threaded sleeve 302. The thread in the first threaded sleeve 301 is a right-hand thread, and the thread in the second threaded sleeve 302 is a left-hand thread. This allows for better adjustment of the distance between the lower support 100 and the upper support 200, enabling support for housings of different sizes, increasing the contact area, reducing overall weight, and ensuring support stability.

[0049] Optionally, the total length of the first threaded sleeve 301 and the second threaded sleeve 302 is greater than or equal to half the length of the adjusting screw 300, and less than or equal to twice the length of the adjusting screw 300. In this way, while ensuring the stability of the connection between the adjusting screw 300 and the lower support 100 and the upper support 200, it can also be adapted to support boxes of various sizes.

[0050] Optionally, the first threaded sleeve 301 and the lower support 100, as well as the second threaded sleeve 302 and the upper support 200, both form a T-shaped structure. This makes the structure more streamlined, providing better and more stable support for the interior of the housing.

[0051] Optionally, the first threaded sleeve 301 and the lower support 100, as well as the second threaded sleeve 302 and the upper support 200, are all integrally formed structures. This results in a more stable and stronger structure, better control over the movement of the lower support 100 and the upper support 200 to support the housing, and improved stability and safety of the support.

[0052] In some other embodiments, the first threaded sleeve 301 and the lower support 100, and the second threaded sleeve 302 and the upper support 200, are optionally detachably connected. This reduces space occupation and facilitates storage after disassembly.

[0053] Optionally, the centers of gravity of both the lower support 100 and the upper support 200 are located on the axis of the adjusting screw 300. This avoids the center of gravity shift affecting the stability of the support, ensuring support stability while enhancing the support effect.

[0054] Optionally, the sides of both the lower support 100 and the upper support 200 away from the screw are planar structures. This allows for closer contact between the lower support 100 and the upper support 200 and the inner wall of the housing, providing more stable and effective support for the housing and further enhancing the support effect on the interior of the housing.

[0055] Optionally, both the lower support 100 and the upper support 200 are provided with a vacuum adsorption plate on the side away from the screw. In this way, the adsorption force of the vacuum adsorption plate can make the support box of the lower support 100 and the upper support 200 more stable, and prevent the lower support 100 and the upper support 200 from shifting.

[0056] like Figure 4 As shown, optionally, the adjusting screw 300 includes a right-hand threaded section 303, a telescopic section 304, and a left-hand threaded section 305. One end of the right-hand threaded section 303 is connected to the lower support 100, one end of the telescopic section 304 is connected to the other end of the right-hand threaded section 303, one end of the left-hand threaded section 305 is connected to the other end of the telescopic section 304, and the other end of the left-hand threaded section 305 is connected to the upper support 200. This makes the structure of the adjusting screw 300 more flexible. The right-hand threaded section 303 and the left-hand threaded section 305 can be used to adjust the movement of the upper support 200 and the lower support 100, while the telescopic section 304 can adjust the overall length of the adjusting screw 300, thus adapting it to support housings of different sizes. Furthermore, by increasing the length of the adjusting screw 300 without increasing the length of the threaded cylinder, its overall weight can be effectively reduced, ensuring the stability of the support.

[0057] Optionally, the sleeve 400 is installed in the middle of the telescopic section 304. This ensures that the upper support 200 and the lower support can move smoothly and stably, and that the telescopic section 304 can be extended and retracted smoothly to adjust the length of the adjusting screw 300.

[0058] Understandably, the telescopic section 304 is a bidirectional telescopic electric telescopic pole. Electric telescopic poles are existing technology, and their specific structure will not be described in detail here.

[0059] like Figure 5-6As shown, optionally, the upper support 200 and the lower support 100 have the same structure. This makes the overall structure more symmetrical and neat, and ensures that the upper support 200 and the lower support 100 can move stably and synchronously to support the inside of the box, while ensuring the balance of the support and enhancing the support effect.

[0060] Optionally, auxiliary support plates 202 are provided on both opposite sides of the upper support 200 and the lower support 100 via damping shafts 201. In this way, by flipping the auxiliary support plates 202 to unfold them, the contact area with the upper and lower side walls of the housing can be increased, the support range can be expanded, and its ability to suppress housing deformation can be further enhanced.

[0061] Optionally, the second threaded sleeve 302 is movably provided with multiple support rods 203, and each auxiliary support plate 202 corresponds to one support rod 203. When the auxiliary support plate 202 is flipped and unfolded, the other end of the support rod 203 abuts against the bottom side of the auxiliary support plate 202. In this way, by using the support rods 203 to support the auxiliary support plate 202, the auxiliary support plate 202 can be kept in a more stable state, preventing the unfolded auxiliary support plate 202 from rotating again and affecting the effectiveness of the support.

[0062] Optionally, a positioning hole is provided on the bottom side of the auxiliary support plate 202. When the auxiliary support plate 202 is flipped and unfolded, the other end of the support rod 203 is inserted into the positioning hole. This makes the placement of the support rod 203 more stable and prevents the support rod 203 from shifting, which would affect the supporting effect on the auxiliary support plate 202.
