Description

Technical Field

[0001] This utility model relates to the field of air conditioner flat roof frame assembly technology, and in particular to an anti-deformation constraint device. Background Technology

[0002] As a key supporting component of the indoor and outdoor unit structure of an air conditioner, the air conditioner frame plays an important role in fixing internal components and ensuring the overall stability and safety of the air conditioner. During the processing and assembly of the air conditioner frame, external forces are generated due to welding and bolt tightening operations. In addition, the stress of the material itself can cause the frame to deform. Therefore, anti-deformation restraint devices are required.

[0003] Traditional anti-deformation restraint devices for air conditioner frames mainly consist of simple fixing frames and rigid clamps. The fixing frames are generally frame-type structures, designed according to the general shape of common air conditioner frames, and serve as basic support. The fixing method of rigid clamps lacks flexibility and is difficult to adapt to air conditioner frames of different shapes and sizes. Existing technology has improved this by adding components such as adjusting bolts or sliders, attempting to make the clamps adaptable to frames of different shapes. In actual use, operators manually adjust the adjusting bolts or sliders according to the shape of the frame to change the position and angle of the clamps to achieve the fixing of the frame. Existing fixing devices can only fix frames with regular shapes and cannot fix frames with irregular shapes. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-deformation constraint device, which aims to improve the problem that existing fixing devices can only fix regular-shaped skeletons and cannot fix irregular-shaped skeletons.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an anti-deformation constraint device, comprising a workbench and a frame. Multiple horizontal plates are fixedly connected to the front and rear sides of the top of the workbench. Multiple sliding grooves are formed on the front and rear sides of the top of the workbench. Multiple sliding seats are slidably connected to the left and right sides of the inner walls of the multiple sliding grooves. A pull rod is slidably connected to the inner wall of each sliding seat. A toothed plate is fixedly connected to the bottom of the pull rod. Multiple toothed grooves are formed at the bottom of the inner wall of each sliding groove. Two springs are fixedly connected to the top of the toothed plate. The tops of the two springs are fixedly connected to the sliding seats. The top of the inner wall of each sliding seat is threadedly connected to a plug. The worktable has a lead screw, and positioning sleeves are fixedly connected to the four corners of the top. Threaded rods are threaded to the top of the inner walls of multiple positioning sleeves. The tops of multiple threaded rods are rotatably connected to the same flattening frame. A sliding plate is slidably connected to the middle of the inner wall of the flattening frame. Multiple rotating rods are rotatably connected to the left and right sides of the top of the flattening frame and the sliding plate. Support arms are fixedly connected to the outer walls of multiple rotating rods. Pressure rods are threaded to the inner walls of multiple support arms. The bottoms of multiple pressure rods are in contact with the top of the frame. An adjustment mechanism is provided at the bottom of the worktable for adjusting the height of the device.

[0006] As a further description of the above technical solution:

[0007] The adjustment mechanism includes multiple hollow sleeves, which are respectively fixedly connected to the four corners of the bottom of the workbench. Each hollow sleeve has an adjusting screw threaded to its inner bottom wall. Each adjusting screw has a support leg rotatably connected to its inner bottom wall. Each adjusting screw has a rotating handle fixedly connected to the middle of its outer wall.

[0008] As a further description of the above technical solution:

[0009] A horizontal groove is provided on the front side of the outer wall of the workbench, and a horizontal ball is slidably connected to the inner wall of the horizontal groove.

[0010] As a further description of the above technical solution:

[0011] An information board is provided on the left side of the front end of the outer wall of the workbench. Screws are threaded to the four corners of the outer wall of the information board, and the rear ends of the screws are threaded to the workbench.

[0012] As a further description of the above technical solution:

[0013] The flattening frame has limit grooves on both the left and right sides of its inner wall, and the slide plate is slidably connected to the two limit grooves.

[0014] As a further description of the above technical solution:

[0015] Multiple protrusions are fixedly connected to the outer walls of the multiple rotating handles, and the surfaces of the multiple protrusions are treated with anti-slip treatment.

[0016] As a further description of the above technical solution:

[0017] Each of the threaded rods has a handle fixedly connected to its top, and the outer walls of each handle are rounded.

[0018] As a further description of the above technical solution:

[0019] Multiple reinforcing plates are fixedly connected to the front and rear sides of the outer walls of the multiple horizontal plates, and the bottom of the multiple reinforcing plates is fixedly connected to the workbench.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the height can be adjusted by the screw on the sliding seat to match the high and low points of the bottom of the frame and prevent it from loosening. The horizontal plate provides basic support, the height of the flattening frame is adjusted by the threaded rod, and the rotating rod, support arm and pressure rod work together to constrain from above. Compared with traditional fixing devices, this device breaks through the limitations and can stably fix irregularly shaped frames, solve existing technical problems and ensure smooth welding.

[0022] 2. In this utility model, the rotating handle is fixedly connected to the adjusting screw. Rotating the rotating handle will drive the adjusting screw to rotate inside the hollow sleeve. The screw can be moved up and down using the thread principle, thereby changing the height of the support leg. This design breaks through the limitations of traditional fixed support. Operators can rotate the rotating handle at different positions to independently adjust the height of each support leg on uneven ground. For example, if one corner of the workbench is too low, rotating the corresponding rotating handle can level it, ensuring the stability of the workbench and providing a stable working foundation for the anti-deformation constraint device, effectively improving the stability and reliability of the work.

[0030] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of an anti-deformation constraint device, comprising a workbench 1 and a frame 17. The workbench 1 serves as the basic load-bearing structure of the entire device, providing a support platform for the frame 17 and other components, ensuring the stability of the entire operation process. Multiple horizontal plates 3 are fixedly connected to the front and rear sides of the top of the workbench 1, directly supporting the frame 17 and distributing its weight, making it more stable when placed on the workbench 1. Multiple sliding grooves 4 are provided on the front and rear sides of the top of the workbench 1, providing movable tracks for sliding seats 5, facilitating adjustment of the position of the sliding seats 5 according to the shape of the frame 17. Multiple sliding seats 5 are slidably connected to the left and right sides of the inner walls of the multiple sliding grooves 4, allowing them to move flexibly within the grooves 4 to meet the support requirements of different shaped frames 17. To meet the requirements, a pull rod 6 is slidably connected to the inner wall of the sliding seat 5, allowing the operator to manually control the position of the toothed plate 7, thereby fixing and moving the sliding seat 5. The bottom of the pull rod 6 is fixedly connected to the toothed plate 7. The engagement and disengagement of the toothed plate 7 with the toothed groove 8 locks and unlocks the sliding seat 5 within the slide groove 4. Multiple toothed grooves 8 are formed on the bottom of the inner wall of the slide groove 4, which cooperate with the toothed plate 7. Two springs 18 are fixedly connected to the top of the toothed plate 7, providing elastic reset. When the pull rod 6 is pulled upwards to separate the toothed plate 7 from the toothed groove 8, releasing the pull rod 6 allows the springs 18 to push the toothed plate 7 back into the toothed groove 8, automatically fixing the position of the sliding seat 5. The tops of both springs 18 are fixedly connected to the sliding seat 5. The inner wall of the movable seat 5 is threaded with a lead screw 9. Its extension length can be adjusted by rotation, thereby adjusting the support height for the bottom of the skeleton 17. This adapts to uneven bottoms of skeletons 17 with different shapes, preventing the skeleton 17 from wobbling during welding. Positioning sleeves 10 are fixedly connected to the four corners of the top of the worktable 1, providing installation positions for the threaded rods 11 and serving to position and guide them, ensuring the stability of the threaded rods 11 during rotational adjustment. Threaded rods 11 are threaded to the top of the inner walls of multiple positioning sleeves 10, engaging with the threads of the positioning sleeves 10 to achieve vertical movement. The tops of multiple threaded rods 11 are rotatably connected to the same flattening frame 12, which constrains the skeleton 17 from above, preventing the skeleton from wobbling. During welding, frame 17 deforms upwards. A sliding plate 13 is slidably connected to the middle of the inner wall of the flattening frame 12, increasing its adaptability to different sized frames 17. Multiple rotating rods 14 are rotatably connected to the top left and right sides of the flattening frame 12 and the sliding plate 13, facilitating adjustment of the angle of the support arms 15 to better adapt to the shape of the frame 17 and achieve multi-angle constraint on the frame 17. Support arms 15 are fixedly connected to the outer walls of the multiple rotating rods 14, providing support for the pressure rods 16. Pressure rods 16 are connected to the inner walls of the multiple support arms 15. Through their connection with the support arms 15, the pressure rods 16 apply pressure to the top of the frame 17, further fixing the frame 17. The bottoms of the multiple pressure rods 16 are all in contact with the top of the frame 17.The bottom of the workbench 1 is equipped with an adjustment mechanism 2, which is used to adjust the height of the device, so that the entire device can adapt to different working scenarios and the usage needs of operators, thereby improving the versatility of the device.

[0032] Specifically, multiple grooves 4 are opened on the front and back sides of the top of the workbench 1. Multiple sliding seats 5 are slidably connected to the left and right sides of the inner wall of the grooves 4. According to the shape of the skeleton 17 to be welded, the pull rod 6 slidably connected to the inner wall of the sliding seat 5 is pulled upward. The toothed plate 7 fixed at the bottom of the pull rod 6 rises synchronously, squeezing the spring 18 fixed at the top of the toothed plate 7 and connected to the sliding seat 5. At this time, the toothed plate 7 separates from the toothed groove 8 at the bottom of the inner wall of the groove 4. In this way, the sliding seat 5 can slide freely in the groove 4. After moving to a suitable position that matches the shape of the skeleton 17, the pull rod 6 is released, the spring 18 returns to its deformation, and pushes the toothed plate 7 to re-engage in the toothed groove 8, thereby fixing the position of the sliding seat 5 and preparing it to support the skeleton 17. The top of the inner wall of the sliding seat 5 is threadedly connected to the screw rod 9. Since the shape of the skeleton 17 is irregular, the height of the screw rod 9 can be adjusted by turning it. Rods 9 support the lowest and highest points of the bottom of the frame 17, effectively preventing the frame 17 from loosening during welding and providing a stable foundation for subsequent welding. Positioning sleeves 10 are fixedly connected to the four corners of the top of the workbench 1. Threaded rods 11 are threadedly connected to the top of the inner wall of the positioning sleeves 10. The top of the threaded rods 11 is rotatably connected to the same flattening frame 12. Rotating the threaded rods 11 can adjust the height of the flattening frame 12 to accommodate frames 17 of different thicknesses. Rotating the rotating rod 14 drives the support arm 15 to rotate. After adjusting to a suitable angle, rotating the pressure rod 16 causes the bottoms of multiple pressure rods 16 to tightly press against the top of the frame 17, constraining and fixing the frame 17 from above. Through the coordinated work of this series of structures, the device can effectively fix the irregularly shaped frame 17 and prevent it from deforming during welding.

[0033] Reference Figure 1 , Figure 2 and Figure 4The adjustment mechanism 2 includes multiple hollow sleeves 201, which are fixedly connected to the four corners of the bottom of the worktable 1, forming a connection between the adjustment mechanism 2 and the worktable 1. This provides a stable installation foundation for subsequent adjustment components, ensuring the stable operation of the adjustment mechanism 2. Each hollow sleeve 201 has an adjusting screw 202 threadedly connected to its inner wall. When the adjusting screw 202 rotates, precise lifting and lowering adjustments can be achieved along the inner wall of the hollow sleeve 201 based on the thread principle, thus meeting the height adjustment requirements of the worktable 1. Multiple adjusting... The inner wall of each screw 202 is rotatably connected to a support leg 203 at its bottom, which is rotatably connected to the adjusting screw 202. This allows the support leg 203 to change its height as the adjusting screw 202 rises and falls, thereby adjusting the overall height of the worktable 1. A rotating handle 204 is fixedly connected to the middle of the outer wall of each of the multiple adjusting screws 202, providing the operator with a convenient structure for applying force. By rotating the rotating handle 204, the operator can easily drive the adjusting screw 202 to rotate, thereby conveniently adjusting the height of the worktable 1, greatly improving the convenience and efficiency of adjustment.

[0034] Specifically, when the height of workbench 1 needs to be adjusted, the operator holds and rotates the handle 204. Since the handle 204 is fixed to the middle of the outer wall of the adjusting screw 202, rotating the handle 204 will cause the adjusting screw 202 to rotate within the hollow sleeve 201. Based on the threaded connection between the hollow sleeve 201 and the adjusting screw 202, the adjusting screw 202 will move up and down along the inner wall of the hollow sleeve 201. The support leg 203, rotatably connected to the bottom of the adjusting screw 202, will rise or fall accordingly, thus changing the overall height of workbench 1. If the ground is uneven, adjustments may be needed. To adjust the level of the workbench 1, the operator can rotate the handle 204 at different positions. For example, if a corner of the workbench 1 is too low, rotating the handle 204 at the corresponding position will raise the adjusting screw 202 at that position, thereby raising the support leg 203. For a corner that is too high, rotating the handle 204 in the opposite direction will lower the adjusting screw 202 and the support leg 203. By independently adjusting the height of the adjusting screw 202 and the support leg 203 at each corner, the workbench 1 can be adjusted to a level state, ensuring that the anti-deformation constraint device can work stably.

[0035] Reference Figure 1 , Figure 3 and Figure 5A horizontal groove 19 is provided on the front side of the outer wall of the workbench 1. A horizontal ball 20 is slidably connected to the inner wall of the horizontal groove 19. The position of the horizontal ball 20 in the horizontal groove 19 can be used to visually indicate whether the workbench 1 is in a horizontal state, assisting the operator in adjustment. An information board 21 is provided on the left side of the front end of the outer wall of the workbench 1. Screws 22 are threadedly connected to the four corners of the outer wall of the information board 21. The rear ends of the screws 22 are threadedly connected to the workbench 1. The information board 21 is fixed to the workbench 1 by the screws 22 threaded at the four corners, and is used to mark equipment information. Limit grooves 23 are provided on the left and right sides of the inner wall of the flattening frame 12. The slide plate 13 is slidably connected to the two limit grooves 23. The slide plate 13 is slidably connected to the limit grooves 23 to limit the movement direction of the slide plate 13, ensuring that it slides stably within the flattening frame 12 and ensuring the realization of the constraint function of the frame 17.

[0036] Specifically, the position of the horizontal ball 20 in the horizontal groove 19 visually indicates whether the workbench 1 is in a horizontal state, assisting the operator in making adjustments. The information board 21 is fixed to the workbench 1 by the screws 22 connected by four corner threads, and is used to mark equipment information for the operator's convenience. The slide plate 13 is slidably connected to the limit groove 23, which restricts the movement direction of the slide plate 13, ensuring that it slides stably within the flattening frame 12, and ensuring the realization of the constraint function of the frame 17.

[0037] Reference Figure 1 , Figure 2 and Figure 5 Multiple rotating handles 204 are fixedly connected to multiple protrusions 24 around their outer walls. The surfaces of the protrusions 24 are treated with anti-slip material, which makes the contact between the operator's hand and the rotating handle more stable when the operator rotates the rotating handle 204 to adjust the height of the support leg 203. This increases friction, prevents hand slippage, and allows for more precise and easy rotation. The tops of multiple threaded rods 11 are fixedly connected to handles 25. The outer walls of the handles 25 are rounded, making the grip more comfortable and preventing hand discomfort or injury caused by the sharp edges of the handles 25, thus improving the operating experience. Multiple reinforcing plates 26 are fixedly connected to the front and rear sides of the outer walls of multiple horizontal plates 3. The bottoms of the reinforcing plates 26 are fixedly connected to the worktable 1, which enhances the connection strength between the horizontal plates 3 and the worktable 1, making the horizontal plates 3 more stable when supporting the frame 17 and less prone to deformation or loosening.

[0038] Specifically, multiple protrusions 24 are fixed around the outer wall of the rotating handle 204, and the surface of the protrusions 24 is treated with anti-slip material. This makes the contact between the operator's hand and the rotating handle 204 more stable when the operator rotates the rotating handle 204 to adjust the height of the support leg 203, increases friction, prevents hand slippage, and allows for more precise and easy rotation. When rotating the threaded rod 11 to adjust the height of the flattening frame 12, the operator's grip on the handle 25 is more comfortable, avoiding hand discomfort or injury caused by the sharp edge of the handle 25, thus improving the operating experience. Multiple reinforcing plates 26 connected to the front and rear sides of the outer wall of the horizontal plate 3 enhance the connection strength between the horizontal plate 3 and the workbench 1, making the horizontal plate 3 more stable when supporting the frame 17, and less prone to deformation or loosening.

[0039] Working principle: First, based on the shape distribution of the skeleton 17 to be welded, the position of the sliding seat 5 is adjusted in advance. By pulling the pull rod 6 upward, the toothed plate 7 fixed at the bottom of the pull rod 6 moves upward, compressing the spring 18, causing the toothed plate 7 to separate from the toothed groove 8 at the bottom of the inner wall of the slide groove 4. At this time, the sliding seat 5 can slide freely in the slide groove 4. After moving to the appropriate position, the pull rod 6 is released, the spring 18 returns to its deformation, and pushes the toothed plate 7 to re-engage in the toothed groove 8, thereby fixing the position of the sliding seat 5. This design can flexibly adapt to the support needs of skeletons 17 with different shapes. Compared with traditional fixing devices, it can better cope with irregular shapes. Next, the screw 9 connected to the top of the inner wall of the sliding seat 5 is screwed to adjust the height of the screw 9. Since the shape of the skeleton is irregular, by adjusting the height of the screw 9, the bottom of the skeleton 17 can be supported separately. The lowest and highest points effectively prevent the skeleton 17 from loosening during welding, providing a stable foundation for subsequent welding. Then, the skeleton 17 is placed on multiple horizontal plates 3 fixedly connected to the front and rear sides of the top of the workbench 1 to further support the skeleton 17. The flattening frame 12 is then placed on the skeleton 17. The flattening frame 12 is adjusted in position by the threaded rod 11 connected to the internal thread of the positioning sleeve 10 at the four corners of the top of the workbench 1. Rotating the threaded rod 11 can adjust the height of the flattening frame 12 to accommodate skeletons 17 of different thicknesses. Then, the rotating rod 14, which is rotatably connected to the top left and right sides of the flattening frame 12 and the slide plate 13, is rotated to drive the support arm 15 to rotate. Then, the pressure rod 16 connected to the inner wall of the support arm 15 is rotated so that the bottom of the multiple pressure rods 16 tightly presses the skeleton 17, constraining and fixing the skeleton 17 from above.

[0040] Furthermore, when the handle 204 is rotated, since the handle 204 is fixed in the middle of the outer wall of the adjusting screw 202, it will drive the adjusting screw 202 to rotate inside the hollow sleeve 201. Based on the principle of threaded connection, the adjusting screw 202 will move up and down along the inner wall of the hollow sleeve 201. The support leg 203 rotatably connected to the bottom of the adjusting screw 202 will change its height as the adjusting screw 202 rises and falls. If the ground is uneven, the operator can independently adjust the height of each support leg 203 by rotating the handle 204 at different positions. For example, when a certain corner of the worktable 1 is too low, the adjusting screw 202 at that position can be raised by rotating the handle 204 at the corresponding position, thereby raising the support leg 203 and adjusting the worktable 1 to a level state.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
