Description

Technical Field

[0001] The utility model relates to the field of rotating connection components, in particular to a shell component and a distribution box with the shell component. Background Art

[0002] In order to improve the appearance and safety of the distribution box, a cover is usually provided on the front side of the frame, and the cover can shield the frame and the internal electrical components.

[0003] In order to flexibly adapt to different installation environments, some distribution boxes use rotating connection components on both sides that can be used as rotation axes and can be separated to open the cover. Specifically, when opening from the left side, the cover is opened and closed with the rotating connection component on the right side as the rotation axis; when opening from the right side, the cover is opened and closed with the rotating connection component on the left side as the rotation axis.

[0004] In order to realize the above-mentioned function of being able to be opened and closed left and right, some distribution boxes in the prior art adopt a connection form in which the cover and the frame are connected by claws that cooperate with the rotating shaft and then rotate around the shaft.

[0005] However, as the length of time used and the number of times the cover is opened and closed increases, the claws tend to age. Tests have found that when the claws age, when the user opens the cover from one side, the claws and the rotating shaft of the rotating connection assembly on the other side are also prone to separation, causing the cover to fall off. The above problem of the cover falling off can be partially solved by setting the tightness of the claws. However, if the claws are set tighter, although the cover is not easy to fall off, overly tight claws will require the user to apply too much force when opening the cover, which is not conducive to user experience. Summary of the invention

[0006] Therefore, how to solve the contradiction that the surface cover is easy to fall off when the clamping claw is too loose, and the switch is inconvenient when the clamping claw is too tight is a technical problem that needs to be solved urgently in the prior art.

[0009] Optionally, the shaft sleeve accessory includes an assembly housing and a first sliding limiter, the inner wall of the assembly housing has a sliding surface for the sliding part to slide against, the first sliding limiter is a limit plate extending in the front-to-back direction, the end of the limit plate in the front-to-back direction is spaced from the sliding surface by a prescribed distance matching the thickness of the sliding part to form a limit opening for the sliding part to pass through; the spring positioning part is a protrusion arranged on the limit plate, and the spring is matched and sleeved on the outer periphery of the protrusion.

[0010] Optionally, a second sliding limiter is further provided on the inner walls on both sides of the assembly housing in the inner and outer directions.

Even if it is a rigid material, it can cope with the working conditions of the switch because of the presence of the spring, thereby effectively taking into account the contradiction between the aging and shedding of the cover and the convenience of opening and closing the cover.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the first embodiment of the utility model, a housing assembly 100 of a distribution box is disclosed, and the housing assembly 100 includes a face frame 1, a face cover 2, and at least two sets of rotating connection assemblies 3 connecting the face frame 1 and the face cover 2. The rotating connection assembly 3 provided in this embodiment includes a detachable shaft 31 and a shaft sleeve 32, so that the face cover 2 can be opened to the left or to the right.

[0031] Figure 1 is a schematic structural diagram of the housing assembly 100 in this embodiment when it is closed. Figure 2 1 is a schematic structural diagram of the housing assembly 100 in this embodiment when it is opened with the two sets of rotating connection assemblies 3 on the right side as the rotation axis. Figure 3 It is a schematic structural diagram of the housing assembly 100 in this embodiment when it is opened with the two groups of rotating connection assemblies 3 on the left side as the rotation axis.

[0032] refer to Figure 1-3 In the housing assembly 100 of this embodiment, the cover 2 covers the front side of the face frame 1, and the central opening of the face frame 1 allows the electrical components to be arranged therein. Figure 1-3 The housing assembly 100 has a first end and a second end opposite to each other in the left and right directions. In order to improve the stability of the rotation of the rotating shaft, the housing assembly 100 is provided with two sets of rotating connection components 3 at the first end and two sets of rotating connection components 3 at the second end. In other embodiments of the utility model, the number of rotating connection components 3 provided at the first end and the second end is not limited, and can also be provided as one set or more than three sets.

[0033] by Figure 1The inner side-outer side direction defined in is the inner side-outer side direction. In this embodiment, each set of rotating connection components 3 is arranged at the end of the inner side-outer side direction. Specifically, the rotating connection components 3 include a shaft 31 and a sleeve 32. In this embodiment, the shaft 31 is fixed to the end of the inner side-outer side of the face cover 2, and the sleeve 32 is arranged at the end of the inner side-outer side of the face frame 1. In other embodiments, the shaft 31 can also be arranged on the face frame 1, and the sleeve 32 can be arranged on the face cover 2, and the utility model does not limit this.

[0034] In this embodiment, the shaft 31 and the sleeve 32 are detachably rotatably connected.

[0035] refer to Figure 2 , Figure 2 The middle shell assembly 100 is opened with the two groups of rotating connection assemblies 3 on the right side as the rotation axis, that is, when the face cover 2 is opened, the shaft 31 and the sleeve 32 of the rotating connection assembly 3 on the right side remain connected, and because the user applies a forward pulling force on the left side of the face cover 2 when opening the face cover 2, the shaft 31 and the sleeve 32 of the rotating connection assembly 3 on the left side are separated from each other, the shaft 31 is still fixed at the end of the face cover 2, and the sleeve 32 is still arranged at the end of the face frame 1.

[0036] Similarly, refer to Figure 3 , Figure 3 The middle shell assembly 100 is opened with the two groups of rotating connection assemblies 3 on the left as the rotation axis, that is, when the cover 2 is opened, the shafts 31 and sleeves 32 of the two groups of rotating connection assemblies 3 on the left are still rotationally connected, while the shafts 31 and sleeves 32 of the two groups of rotating connection assemblies 3 on the right are separated from each other.

[0037] Figure 4 It is a schematic structural diagram (cross-sectional view) of the outer end (first end or second end) of the housing assembly 100 of this embodiment when the sleeve 32 is sleeved on the outer periphery of the shaft 31 .

[0038] refer to Figure 4 In this embodiment, the sleeve 32 is formed from a piece of metal sheet by folding, punching and other processes. The sleeve 32 at least includes a spring contact portion 320, a sliding portion 321 and a gripping portion 322, wherein the spring contact portion 320 is a portion for the spring 33 to contact. The sliding portion 321 is a metal sheet extending inward and outward directions, and constitutes the main body of the sleeve 32. The sliding portion 321 can slide in the sleeve fitting 34, so when it is removed from the sleeve, the sleeve 32 is not moved. Figure 4 When the cover 2 is opened and closed at one end as shown in FIG. 1 , the sleeve 32 can be displaced in the inward and outward directions to avoid the forward and backward movement of the shaft 31 .

[0039] The gripping portion 322 is disposed at the left end of the sleeve 32, connected to the sliding portion 321, and partially surrounds the outer circumference of the shaft 31. Specifically, in this embodiment, the gripping portion 322 is in an arc shape matching the shape of the shaft 31, and this shape can facilitate the shaft 31 to rotate therein without hindrance.

[0040] In this embodiment, reference Figure 5 The gripping portion 322 extends outward from the rear inner side of the shaft 31, then turns inward along the outer contour of the shaft 31, and then extends to the outer front side of the shaft 31. This shape of the gripping portion 322 has at least the following advantages:

[0041] when Figure 5 When the end shown in FIG. 3 is used as the rotation axis, the gripping portion 322 of this shape can maintain a larger circumferential range of the shaft 31, thereby making the rotation process more stable and smooth.

[0042] when Figure 5 When the end shown in FIG. 1 is opened from the closed state, the shaft 31 moves forward from the position indicated by the solid line to the position indicated by the dotted line as the cover 2 is opened. In the solid line position, the shaft 31 presses against the portion of the grip 322 located on the outer front side of the shaft 31, and the stress generated by the pressing has an outward component, thereby driving the sleeve 32 to move outward to avoid the shaft 31 from entering or exiting.

[0043] When Figure 5 When the end shown in FIG. 1 changes from the open state to the closed state, the shaft 31 moves backward from the position indicated by the dotted line to the position indicated by the solid line. At the dotted line position, the shaft 31 and the end of the gripping portion 322 press against each other, and the pressing force of the shaft 31 on the end of the gripping portion 322 also has an outward component, thereby driving the sleeve 32 to move outward to avoid the shaft 31 from entering or exiting.

[0044] In the above manner, when the cover 2 is opened or closed, the shaft 31 can press against the sleeve 32 to generate a force that drives the sleeve 32 to move outward, thereby avoiding the shaft 31 from entering or exiting. Because the sleeve 32 is slidably mounted in the sleeve fitting 34, the movement of the sleeve 32 outward will not be restricted, and the shaft 31 can be effectively avoided from entering or exiting. On the other hand, due to the presence of the spring 33, when the shaft 31 is completely disengaged from the sleeve 32, the spring 33 can reset the position of the sleeve 32, ensuring that when the cover 2 is closed next time, the sleeve 32 can be in a position where part of the thrust of the shaft 31 when entering is converted into a position that moves the sleeve 32 outward. When the shaft 31 is in a closed state partially surrounded by the sleeve 32, the spring 33 can pull the sleeve 32 inward, so that the sleeve 32 is tightly pressed against the shaft 31, ensuring the stability of the shaft 31 when the rotating connection assembly 3 is rotated with the rotating connection assembly 3 as the rotating axis, and ensuring that the shaft 31 is not easy to fall off from the sleeve 32.

[0045] In this embodiment, the method of assembling the spring 33 and the sleeve 32 is as follows: Figure 6 and Figure 7 As shown, Figure 6 is a front view of a schematic structural diagram of the rotating connection assembly 3 in this embodiment, Figure 7 It is a stereoscopic diagram of the structural schematic diagram of the rotating connection component 3.

[0046] The rotating connection assembly 3 includes a shaft 31, a shaft sleeve 32, a shaft set fitting 34 and a spring 33. The shaft set fitting 34 is fixedly connected to the face frame 1 or the face cover 2. In this embodiment, the shaft set fitting 34 is fixedly connected to the face frame 1 and embedded in the end of the face frame 1. The shaft sleeve 32 is installed on the shaft set fitting 34, and is specifically limited by the shaft set fitting 34. In the absence of other external forces, the shaft sleeve 32 is pulled by the spring 33 to spontaneously retract the end of the face frame 1, and when subjected to an outward force, it can overcome the elastic deformation of the spring 33 and slide outward for a specified stroke. The shaft set fitting 34 can limit the shaft sleeve 32 to stably and smoothly slide along the inward and outward directions for a specified stroke.

[0047] The following combination Figure 6 and Figure 7 The following describes how the shaft sleeve fitting 34 cooperates with the shaft sleeve 32 and the spring 33 to achieve the above functions. Figure 6 and Figure 7 The shaft sleeve assembly 34 has an assembly housing 340, which is surrounded by a plurality of walls, including a lower wall 341, a side wall 342 and an end wall 343, and the end wall 343 and the side wall 342 are both arranged perpendicular to the lower wall 341. The inner surface of the lower wall 341 is a sliding surface 344 for the sliding part 321 to slide along the surface thereof, and the inner surface of the end wall 343 is abutted by the end of the shaft sleeve 32, limiting the deepest position of the shaft sleeve 32 that can enter the shaft sleeve assembly 34.

[0048] The shaft sleeve fitting 34 is open at the other end opposite to the end wall 343, allowing the shaft sleeve 32 to extend. A limit plate 345 is also provided between the end of the extended portion of the shaft sleeve 32 (i.e., the gripping portion 322) and the end wall 343. The limit plate 345 is a first sliding limiter, which is used to stably limit the sliding direction of the shaft sleeve 32 to the inner and outer directions.

[0049] Specifically, refer to Figure 8 There is a specified distance d1 between the limit plate 345 and the sliding surface 344 of the lower wall 341, and the specified distance d1 matches the thickness of the sliding portion 321 of the sleeve 32, that is, it is equal to or slightly larger than the thickness of the sliding portion 321 of the sleeve 32, thereby forming a limit opening 346 between the bottom of the limit plate 345 and the sliding surface 344 for the sliding portion 321 of the sleeve 32 to pass through.

[0050] refer to Figure 6 and Figure 7 The second sliding stopper 347 is also provided on the inner surface of the two side walls 342 of the assembly housing 340. The second sliding stopper 347 is a rib extending in the inner and outer directions and protruding from the inner surface of the side wall 342. In the inner and outer directions, the second sliding stopper 347 is located between the first sliding stopper (stopper plate 345) and the spring contact portion 320. Figure 8 The distance between the bottom of the second sliding stopper 347 and the sliding surface 344 of the lower wall 341 is d2, which also matches the thickness of the sliding portion 321 of the sleeve 32, that is, equal to or slightly greater than the thickness of the sliding portion 321 of the sleeve 32. The limiting plate 345 and the second sliding stopper 347 can limit the sliding portion 321 at different positions in the inner and outer directions, so that the sliding of the sliding portion 321 is stably maintained in the inner and outer directions.

[0051] In this embodiment, reference Figure 4 The sliding portion 321 is the portion of the sleeve 32 that slides in the inward and outward directions. At the end of the sliding portion 321 that is away from the gripping portion 322, the sleeve 32 is bent to extend in the front-to-back direction to form a spring abutment portion 320. On the other side, a spring positioning portion 348 is provided on the side of the limiting plate 345 that faces the spring abutment portion 320. The spring positioning portion 348 is a convex block protruding from the surface of the limiting plate 345. One end of the spring 33 is matingly sleeved on the outer periphery of the convex block, and the other end abuts against the spring abutment portion 320. The spring 33 is a compression spring. In other words, even in a situation such as Figure 4 In the state shown in which the spring 33 is not further compressed, the spring 33 is still in a compressed state or a state without force. In this way, as long as the spring abutment 320 moves slightly outward to make the spring 33 slightly compressed, the spring 33 can apply a force to the spring abutment 320 to the right, so that the shaft sleeve 32 always has a tendency to return to the right.

[0052] refer to Figure 5-Figure 7 In this embodiment, both side ends of the sliding portion 321 and the spring abutting portion 320 are bent to form abutting surfaces 323, and the extension direction of the abutting surfaces 323 is parallel to the inner and outer directions. If the abutting surfaces 323 are not bent, the end of the spring abutting portion 320 will form point contact with the side wall 342, which may generate noise or hinder sliding during the sliding process. By bending to form the abutting surface 323, on the one hand, the spring abutting portion 320 forms a surface contact with the inner surface of the side wall 342, which can make the sliding smoother. On the other hand, because part of the dead weight of the cover 2 will be applied to the sleeve 32, the structural strength of the sleeve 32 can also be improved by bending to form the abutting surface 323 as described above.

[0053] In particular, in cooperation with the abutment surface 323, the assembly housing 340 is further provided with a sliding stroke limiting portion 349 on both inner walls (inner surfaces of the side walls 342) in the inner and outer directions. The sliding stroke limiting portion 349 is a rib extending in the front-to-back direction and protruding from the inner surface of the side wall 342. Figure 6 When the sleeve 32 slides to the right and the right end of the abutment surface 323 of the spring abutment portion 320 abuts against the left end of the sliding stroke limiting portion 349, the sleeve 32 cannot continue to slide to the right, that is, the right side surface of the end wall 343 to the left side surface of the sliding stroke limiting portion 349 is the travel range for the sleeve 32 to slide.

[0054] In addition, in this embodiment, reference Fig. 9 The shaft set accessory 34 also includes a spring limiting portion 350, which is arranged opposite to the sliding surface 344 with the spring 33 in between. The spring limiting portion 350 is constructed as an arch structure matching the shape of the spring 33, and is used to limit the position of the spring 33 from the front side to prevent the spring 33 from falling out from the front side when it is bent due to uneven force.

[0055] In actual use, taking the case where a human body may lean on the face cover 2 of the distribution box as an example, the distribution box may be subjected to a backward extrusion force. Because the shaft sleeve 32 is made of a metal sheet by bending, punching and other processes, if a large extrusion force is directly applied to the shaft sleeve 32, it may cause irreversible deformation of the shaft sleeve 32, making it difficult for the shaft sleeve 32 to accurately dock with the shaft 31. In this embodiment, the shaft sleeve accessory 34 also includes two shaft supports 351, and the two shaft supports 351 are respectively arranged adjacent to the two gripping portions 322, and are arranged corresponding to the shaft 31 in the front and rear directions. The shaft support 351 can limit the backward movement stroke of the face cover 2. When the face cover 2 is squeezed backward, the extrusion force will be borne by the shaft support 351, and will not or less will be applied to the shaft sleeve 32, thereby preventing the shaft sleeve 32 from deforming and ensuring the service life and durability of the rotating connection assembly 3.

[0056] In the above manner, the housing assembly 100 of the distribution box provided in this embodiment can cope with the opening and closing processes of the cover 2 and various working conditions when used as a rotating shaft. The spring 33 is not easy to age, and the elastic coefficient and the preset deformation are adjustable, so that the magnitude of the force required to switch the cover 2 can be adjusted more accurately. Accordingly, because the sleeve 32 can slide in the inner and outer directions, it is not required that the material of the sleeve 32 has a certain elasticity. Even if it is a rigid material, it can cope with the working conditions of the switch because of the presence of the spring 33, thereby effectively taking into account the contradiction between the aging and shedding of the cover 2 and the convenience of the cover 2.

[0057] It should be noted that, although in the present embodiment, the shaft 31 is arranged at the end of the face cover 2, and the shaft sleeve 32 is correspondingly arranged at the end of the face frame 1, and accordingly, the gripping portion 322 is configured to be an arc extending from the rear inner side of the shaft 31 to the outer front side of the shaft 31, the above does not constitute a limitation on the present utility model. In other embodiments, the arrangement positions of the shaft 31 and the shaft sleeve 32 can be reversed, and accordingly, the gripping portion 322 can be configured to be a shape extending from the front inner side of the shaft 31 to the outer rear side of the shaft 31. In addition, the shape of the gripping portion 322 is not limited to a circular arc, but can be a broken line or a non-circular arc.

[0058] In the present embodiment, the spring 33 is connected to the sleeve 32, pulling the sleeve 32 inward to press against the shaft 31, so that the rotating connection component 3 is more stable when used as a rotating shaft. However, in other embodiments, the spring 33 can also be connected to the shaft 31, pulling the shaft 31 outward or inward to press against the sleeve 32, which can also make the rotating connection component 3 more stable when used as a rotation. The present invention is not limited to a specific connection form.

[0059] It should be noted that, although in this embodiment, the specific structure and use method of the shell assembly are explained by taking the distribution box as an example, the shell assembly provided by the utility model is not limited to its application as the shell of a distribution box. In other embodiments, the shell assembly can also be applied to any other suitable products that need to rotate to open or close covers or doors and other coverings.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
