Description

Technical Field

[0001] The present application belongs to the field of structural design technology, and specifically relates to an adjustable hinge and a method of use. Background Art

[0002] Sheet metal structure cabinets are often used in power electronic products due to their high strength and easy processing. The installation position of the cabinet door directly affects the sealing and aesthetics of the product, so high requirements are placed on the installation accuracy of the cabinet door. In practical applications, sheet metal structure cabinets often use hinges to assemble the cabinet door. This connection method is relatively flexible and can meet the needs of cabinet door opening and closing to a certain extent. However, after the rough assembly of the cabinet door is completed, due to the influence of various factors, its position is often difficult to accurately reach the ideal state, so the cabinet door position needs to be carefully adjusted to move it accurately to the corresponding position, so as to meet the strict requirements of sealing and aesthetics.

[0003] With the continuous development and progress of power electronic product technology, its power is showing a trend of increasing. In order to meet the high-power operation requirements, large-sized sheet metal structure boxes have emerged and are widely used. Correspondingly, the size of the cabinet door has also increased to match the larger cabinet specifications. In addition, the functions of modern power electronic products are becoming increasingly complex and diverse, which often requires a large number of electrical components to be installed on the cabinet door, such as display screens for information display and operation interaction, fans for heat dissipation and ventilation, and filters for filtering dust and impurities. The increase of these electrical components undoubtedly further increases the weight of the cabinet door.

[0004] In the production process, the assembly of large-sized cabinet doors has become a more difficult link. Due to its large size, heavy weight and the installation and debugging of many parts, it will take up more working hours. The production process that could have been completed quickly has become slow due to the assembly of large-sized cabinet doors, which not only affects production efficiency, but may also cause delays in the entire production plan. During transportation, since the vehicle will inevitably vibrate during driving, this vibration will have an impact on the assembled cabinet doors. In addition, the hinge shaft will also produce mechanical wear during subsequent use. These factors combined will cause the cabinet door assembly position to change. Once the cabinet door position changes, the appearance of the product will be damaged. The originally flat and symmetrical cabinet doors may become skewed, the gaps may be uneven, etc., which seriously affects the overall aesthetics of the product.

[0005] Due to the large weight and size of the cabinet door, and the fact that it is equipped with a variety of electrical components, it is very difficult to adjust the position of the heavy cabinet door by manpower. When faced with such a heavy cabinet door, it is often difficult for manpower to exert sufficient and accurate force to adjust its position. Even if the adjustment is made reluctantly, the adjustment effect is not ideal. A lot of time and effort may be spent, but the cabinet door position cannot be accurately adjusted to the right position, and the high standard requirements for sealing and aesthetics of the product cannot be met. Therefore, an adjustable hinge and a method of use are urgently needed. Summary of the invention

[0006] The purpose of the present invention is to provide an adjustable hinge and a method of use, so as to overcome the shortcomings of the prior art that the cabinet door cannot be adjusted accurately, maintenance is difficult when the cabinet door is abnormally displaced, and the high standards of sealing and aesthetics cannot be met.

[0007] In order to achieve the above object, the present invention provides the following technical solutions: In a first aspect, the present invention provides an adjustable hinge, which is arranged between a main box body and a cabinet door, wherein the hinge comprises a main box body hinge and a rotating shaft, wherein the main box body hinge is rotatably connected to the cabinet door hinge via the rotating shaft, and a cabinet door rigid fixing member is fixedly connected to the cabinet door hinge; through the cooperation of the main box body hinge, the rotating shaft and the cabinet door hinge, the cabinet door can be flexibly opened and closed relative to the main box body; The front of the cabinet door hinge is provided with a first adjustment hole, the side of the cabinet door hinge is provided with a side waist hole and a first side threaded hole, the bottom surface of the cabinet door hinge is provided with a bottom threaded hole, and the top surface of the cabinet door hinge is provided with a top threaded hole; The front side of the cabinet door rigid fixing piece is provided with a second adjustment hole, and the side side of the cabinet door rigid fixing piece is provided with a second side threaded hole; The first adjustment hole and the second adjustment hole are connected by setting a cabinet door hinge fastening screw, the side waist hole and the second side threaded hole are connected by setting a first adjustment screw, the first side threaded hole is provided with a second adjustment screw, the bottom threaded hole is provided with a bottom adjustment screw, and the top threaded hole is provided with a top adjustment screw. The position of the cabinet door can be adjusted in multiple directions by using each adjustment hole and threaded hole and the corresponding screws. For example, the overall relative position of the cabinet door can be adjusted to a certain extent by using the first adjustment hole and the second adjustment hole and the cabinet door hinge fastening screw; the combination of the side waist hole and the first adjustment screw can realize the fine adjustment of the cabinet door in the side direction, and the first side threaded hole and the second adjustment screw, the bottom threaded hole and the bottom adjustment screw, and the top threaded hole and the top adjustment screw correspond to more precise position adjustment of the cabinet door in the side, bottom and top directions, respectively, so that the cabinet door can be accurately positioned to an ideal position that meets the sealing and aesthetic requirements.

[0008] Furthermore, the diameter of the first adjustment hole is larger than the diameter of the cabinet door hinge fastening screw.

[0009] Furthermore, the main box hinge of the hinge is fixed on the main box, and the cabinet door rigid fixing piece is connected to the cabinet door. After assembly, the cabinet door rigid fixing piece and the cabinet door are relatively fixed in position and move together.

[0010] Furthermore, the hinge and the main box are connected by screws, rivets or welding.

[0011] Furthermore, the hinge and the cabinet door are connected by welding.

[0012] In a second aspect, the present invention provides a method for using an adjustable hinge, comprising: The main box hinge of the hinge is fixed on the main box, and the cabinet door rigid fixing piece is connected to the cabinet door; The cabinet door can be moved up, down, left and right by adjusting the screws on the hinge; When the cabinet door needs to be rotated counterclockwise for adjustment, the cabinet door hinge of the upper hinge of the cabinet door moves to the left, and the cabinet door hinge of the lower hinge moves to the right; When the cabinet door needs to be rotated clockwise for adjustment, the cabinet door hinge of the upper hinge of the cabinet door moves to the right, and the cabinet door hinge of the lower hinge moves to the left.

[0013] Furthermore, the specific steps for the hinge to realize the upward movement of the cabinet door are: Loosen the first adjustment screw, top adjustment screw and door hinge fastening screw; Tighten the bottom adjustment screw, and the cabinet door rigid fixing piece moves upward under the push of the bottom adjustment screw, thereby driving the cabinet door connected to the cabinet door rigid fixing piece to move upward.

[0014] The upward movement of the cabinet door can be controlled by pushing the bottom adjustment screw, which effectively solves the problem of the cabinet door being too low due to various reasons and needs to be adjusted upward, ensuring the sealing and aesthetics of the product. At the same time, compared with the traditional method of lifting the cabinet door for adjustment, this method is more stable and reliable, and will not cause additional damage or deformation to the cabinet door and hinge structure.

[0015] Furthermore, the specific steps for the hinge to realize the downward movement of the cabinet door are: Loosen the first adjustment screw, bottom adjustment screw and door hinge fastening screw; Tighten the top adjustment screw, and the cabinet door rigid fixing piece moves downward under the push of the top adjustment screw, thereby driving the cabinet door connected to the cabinet door rigid fixing piece to move downward.

[0016] The downward movement of the cabinet door can be controlled by moving the top adjustment screw downward. This adjustment method based on the hinge structure avoids damage to the cabinet door and hinge due to uneven or excessive force during traditional manual adjustment.

[0017] Furthermore, the specific steps for the hinge to realize the cabinet door moving to the left are: Loosen the second adjustment screw, top adjustment screw and cabinet door hinge fastening screw; Tighten the first adjusting screw, and the cabinet door rigid fixing piece moves to the left under the traction of the first adjusting screw, thereby driving the cabinet door connected to the cabinet door rigid fixing piece to move to the left.

[0018] The traction effect of the first adjustment screw can be used to control the amount of leftward movement of the cabinet door. Compared with the traditional method of adjusting the cabinet door by pushing or pulling the cabinet door manually, this method is more stable and reliable, and reduces the risk of cabinet door deformation or hinge damage due to improper human operation.

[0019] Furthermore, the specific steps for the hinge to move the cabinet door to the right are: Loosen the first adjustment screw, top adjustment screw and door hinge fastening screw; Tighten the second adjusting screw, and the cabinet door rigid fixing piece moves to the left under the traction of the second adjusting screw, thereby driving the cabinet door connected to the cabinet door rigid fixing piece to move to the right.

[0020] The rightward movement of the cabinet door can be controlled by moving the cabinet door to the right through the second adjusting screw.

[0021] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention provides an adjustable hinge, which can be used to simply, quickly and accurately install the main box body and the cabinet door. After the cabinet door is roughly assembled, the installation size of the cabinet door can be easily fine-tuned through the adjusting screws of the adjustable hinge, thereby shortening the assembly time. The cabinet door position adjustment accuracy is high and the adjustment method is simple; it can complete the adjustment in four directions: left, right, up and down. For cabinet doors that are large in size, heavy in weight and equipped with many electrical components, it is difficult for traditional installation methods to meet high-precision requirements. The adjustable hinge provided by the present invention can effectively overcome the various displacement problems caused by the characteristics of the cabinet door itself and during transportation and use through the multi-directional fine adjustment function, so that the cabinet door installation position is more accurate and the sealing of the product is ensured.

[0022] The present invention also provides a method for using an adjustable hinge. In the assembly process of large-sized cabinet doors, rough adjustment by manpower in the past not only has poor effect but is also time-consuming and laborious. When the cabinet door position is abnormally displaced, the method for using the adjustable hinge provided by the present invention can easily adjust the cabinet door position in multiple dimensions by using the cooperation of each adjustment hole and screw, quickly adjust the cabinet door back to the correct position, simplify the product maintenance process and maintenance time, reduce the large amount of man-hours occupied by the cabinet door position adjustment, and improve production efficiency.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0035] Example 1 See also Figures 1 to 4 An adjustable hinge is arranged between the main box body 1-1 and the cabinet door 1-2, and consists of 9 parts, 2-1 is the main box body hinge, 2-2 is the rotating shaft, 2-3 is the cabinet door hinge, 2-4 is the cabinet door rigid fixing part, 2-5 is the first adjusting screw, 2-6 is the second adjusting screw, 2-7 is the bottom adjusting screw, 2-8 is the top adjusting screw, and 2-9 is the cabinet door hinge fastening screw.

[0036] like Figure 1 to Figure 2 As shown, the hinge 1-3 includes a main box hinge 2-1 and a rotating shaft 2-2. The main box hinge 2-1 is rotatably connected to the cabinet door hinge 2-3 through the rotating shaft 2-2, so as to realize the opening and closing action of the cabinet door 1-2 relative to the main box 1-1. The main box hinge 2-1 is the part connecting the hinge 1-3 and the main box 1-1, providing a fixing foundation for the entire hinge structure on the main box 1-1. The cabinet door 1-2 can be fixed to the cabinet door 1-2 by a suitable connection method (such as screw connection, rivet connection, etc.). The cabinet door 1-2 is tightly connected to the main box body 1-1 by connection or welding to ensure that it remains stable during opening and closing of the cabinet door 1-2 and use; the cabinet door hinge 2-3 is fixedly connected with a cabinet door rigid fixing part 2-4, and the rotating shaft 2-2 is assembled in the rotating shaft holes of the main box body hinge 2-1 and the cabinet door hinge 2-3, and the main box body hinge 2-1 and the cabinet door hinge 2-3 can rotate around the rotating shaft 2-2; the cabinet door hinge 2-3 is fixedly connected with a cabinet door rigid fixing part 2-4.

[0037] like Figure 3 As shown, the front of the door hinge 2-3 is provided with a first adjustment hole 3-1, the side of the door hinge 2-3 is provided with a side waist hole 3-2 and a first side threaded hole 3-3, the bottom surface of the door hinge 2-3 is provided with a bottom threaded hole 3-4, and the top surface of the door hinge 2-3 is provided with a top threaded hole 3-5.

[0038] like Figure 4As shown, the front of the cabinet door rigid fixing member 2-4 is provided with a second adjustment hole 4-1, and the side of the cabinet door rigid fixing member 2-4 is provided with a second side threaded hole 4-2.

[0039] The cabinet door hinge fastening screw 2-9 connects the first adjustment hole 3-1 of the cabinet door hinge 2-3 and the second adjustment hole 4-1 of the cabinet door rigid fixing 2-4. Since the diameter of the first adjustment hole 3-1 is larger than the diameter of the screw, when adjusting other screws, there is a certain relative displacement space between the cabinet door hinge 2-3 and the cabinet door rigid fixing 2-4, which can adjust the overall relative position of the cabinet door 1-2 to a certain extent, and after the adjustment is completed, the two are fastened to ensure the stability of the cabinet door 1-2 structure; The first adjusting screw 2-5 is used to connect the side waist hole 3-2 of the cabinet door hinge 2-3 and the second side threaded hole 4-2 of the cabinet door rigid fixing member 2-4. By screwing in or out the first adjusting screw 2-5, the cabinet door 1-2 can be fine-tuned in the side direction to change the relative position of the cabinet door 1-2 in the horizontal direction; the second adjusting screw 2-6 is installed on the first side threaded hole 3-3 of the cabinet door hinge 2-3; The bottom adjustment screw 2-7 is set in the bottom threaded hole 3-4 of the cabinet door hinge 2-3. By rotating the bottom adjustment screw 2-7, the cabinet door rigid fixing member 2-4 can be pushed to move upward, thereby driving the cabinet door 1-2 to move upward, so as to adjust the bottom position of the cabinet door 1-2 in the vertical direction, and ensure that the bottom of the cabinet door 1-2 is closely matched with the main box 1-1; The top adjustment screw 2-8 is located at the top threaded hole 3-5 of the cabinet door hinge 2-3. Its function is opposite to that of the bottom adjustment screw 2-7. When tightened, it can push the cabinet door rigid fixing part 2-4 to move downward, so that the cabinet door 1-2 moves downward, and is used to accurately adjust the vertical position of the top of the cabinet door 1-2 to ensure the sealing and appearance of the top of the cabinet door 1-2.

[0040] The main box hinge 2-1 of the hinge 1-3 is fixed on the main box 1-1, and the cabinet door rigid fixing member 2-4 is connected to the cabinet door 1-2. After assembly, the cabinet door rigid fixing member 2-4 and the cabinet door 1-2 are relatively fixed in position and move together.

[0041] The hinge 1-3 and the main box body 1-1 are connected by screw connection, rivet connection or welding connection; the hinge 1-3 and the cabinet door 1-2 are connected by welding connection.

[0042] Example 2 See also Figures 6 to 9 A method for using an adjustable hinge is to first fix the main cabinet hinge 2-1 of the hinge 1-3 on the main cabinet 1-1, and connect the cabinet door rigid fixing part 2-4 to the cabinet door 1-2, thereby constructing a basic structure in which the cabinet door 1-2 is connected to the main cabinet 1-1 through the hinge 1-3, so that the position and angle of the cabinet door can be adjusted later by operating the various components on the hinge.

[0043] The specific steps for the hinge 1-3 to realize the upward movement of the cabinet door 1-2 are as follows: first loosen the first adjustment screw 2-5, the top adjustment screw 2-8 and the cabinet door hinge fastening screw 2-9; loosening the first adjustment screw 2-5 can release its restriction on the cabinet door rigid fixing part 2-4 in the lateral direction, loosen the top adjustment screw 2-8 to free up the top space for upward movement, and loosen the cabinet door hinge fastening screw 2-9 to allow relative displacement between the cabinet door hinge 2-3 and the cabinet door rigid fixing part 2-4; then tighten the bottom adjustment screw 2-7, and the bottom adjustment screw 2-7 and the threaded hole on the bottom surface of the cabinet door hinge 2-3 act to generate an upward thrust, pushing the cabinet door rigid fixing part 2-4 to move upward. Since the cabinet door rigid fixing part 2-4 is tightly connected to the cabinet door 1-2 and relatively fixed, it drives the cabinet door 1-2 to move upward.

[0044] The specific steps for the hinge 1-3 to realize the downward movement of the cabinet door 1-2 are: loosen the first adjustment screw 2-5, the bottom adjustment screw 2-7 and the cabinet door hinge fastening screw 2-9; loosen the first adjustment screw 2-5 to eliminate side interference, loosen the bottom adjustment screw 2-7 to remove the bottom support restriction, and loosen the cabinet door hinge fastening screw 2-9 to create relative displacement conditions; tighten the top adjustment screw 2-8, and the top adjustment screw 2-8 cooperates with the threaded hole on the top surface of the cabinet door hinge 2-3 to generate downward pressure, pushing the cabinet door rigid fixing 2-4 to move downward, thereby driving the cabinet door 1-2 to move downward.

[0045] The specific steps of hinge 1-3 to realize leftward movement of cabinet door 1-2 are as follows: loosen the second adjustment screw 2-6, the top adjustment screw 2-8 and the cabinet door hinge fastening screw 2-9; loosen the second adjustment screw 2-6 to release the side restriction on the other side, loosen the top adjustment screw 2-8 to reduce the top constraint, and loosen the cabinet door hinge fastening screw 2-9 to facilitate the relative displacement of the cabinet door hinge 2-3 and the cabinet door rigid fixing part 2-4; tighten the first adjustment screw 2-5, and the first adjustment screw 2-5 and the side structure of the cabinet door hinge 2-3 (such as the side waist hole, etc.) generate a leftward pulling force, which pulls the cabinet door rigid fixing part 2-4 to move to the left, thereby driving the cabinet door 1-2 to move to the left.

[0046] The specific steps of hinge 1-3 to realize the rightward movement of cabinet door 1-2 are as follows: loosen the first adjustment screw 2-5, the top adjustment screw 2-8 and the cabinet door hinge fastening screw 2-9; loosen the relevant screws to eliminate interference and constraints and create displacement conditions; tighten the second adjustment screw 2-6, and the second adjustment screw 2-6 and the first side threaded hole on the side of the cabinet door hinge 2-3 will produce a rightward pulling force, pulling the cabinet door rigid fixing part 2-4 to move to the left (because the structural design allows the cabinet door to move to the right by pulling to the left), thereby driving the cabinet door 1-2 to move to the right.

[0047] When the cabinet door 1-2 needs to be rotated counterclockwise for adjustment, the cabinet door hinge 2-3 of the upper hinge 1-3 of the cabinet door 1-2 is moved to the left, and the cabinet door hinge 2-3 of the lower hinge 1-3 is moved to the right. By combining the movement operations of the upper and lower hinges in different side directions, the cabinet door can be rotated counterclockwise with the hinge as the axis, which can be used to correct the angle deviation of the cabinet door caused by installation or use.

[0048] When the cabinet door 1-2 needs to be adjusted by rotating clockwise, the cabinet door hinge 2-3 of the upper hinge 1-3 of the cabinet door 1-2 is moved to the right, and the cabinet door hinge 2-3 of the lower hinge 1-3 is moved to the left. The operation mode is opposite to the counterclockwise rotation adjustment. By adjusting the side movement direction of the upper and lower hinges, the cabinet door can rotate clockwise to meet different installation and use requirements, ensuring that the cabinet door 1-2 and the main box 1-1 can also meet the sealing and aesthetic requirements in terms of angle.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
