Abstract
Description
Technical Field
[0001] This utility model relates to the field of stop structure technology, and in particular to a connector and a movable stop waterproof structure. Background Technology
[0002] The stop structure of sheet metal parts is an important design element used to achieve positioning, limiting, and connection between parts. According to the type of stop, it can be divided into male stops and female stops. Male stops are usually designed on sheet metal parts with thinner walls and are formed into a raised structure by adding glue or bending. Female stops are usually designed on sheet metal parts with thicker walls and are formed into a recessed structure by removing glue or bending.
[0003] Traditional sheet metal parts are difficult to form an integral stop structure directly through injection molding or compression molding due to the material characteristics, which limits their waterproof performance. They usually have to rely on additional seals (such as rubber rings) or complex welding processes to achieve waterproof function. However, this method has problems such as high cost, complicated assembly and uneven glue distribution, making it difficult to consistently achieve the IP67 protection level.
[0004] Therefore, this utility model proposes a connector and a waterproof structure for a movable stop. Utility Model Content
[0005] The utility model of this invention provides a connector and a waterproof structure for movable stop, which mainly solves the problem that traditional sheet metal parts are difficult to form an integral stop structure directly through injection molding or compression molding due to the material characteristics, resulting in limited waterproof performance. Usually, waterproof function can only be achieved by relying on additional seals or complex welding processes, but this method has the problems of high cost, complex assembly and uneven glue distribution.
[0006] This utility model proposes a connector, which includes a main structure and a folded edge arranged perpendicularly to each other, and the folded edge protrudes outward; the horizontal height of the folded edge is lower than the top horizontal height of the main structure.
[0007] Preferably, the folded edge is located at the bottom end of the main structure.
[0008] Preferably, the connection end of the main structure with the folded edge is recessed to form an anti-groove, and the bottom surface of the anti-groove is a concave-convex surface.
[0009] Preferably, the connector is made of sheet metal.
[0010] This utility model also proposes a movable stop waterproof structure, including the aforementioned connector, and further including:
[0011] The lower shell has an open end face at the top; the connector is built into the lower shell, and the outer contour of the folded edge of the connector is equal to the inner contour of the lower shell; a sealing element is filled between the connector and the inner side of the lower shell.
[0012] The upper shell is detachably connected to the top of the lower shell.
[0013] Preferably, the sealant is a cool-cured sealant.
[0014] Preferably, the lower shell comprises:
[0015] A limiting structure, with a protrusion formed on the inner side of the lower shell, supports and fixes the folded edge of the connector.
[0016] Preferably, both the upper edge of the lower shell and the lower edge of the upper shell are provided with through holes for external fasteners to pass through and fix.
[0017] Preferably, the bottom end of the upper shell is recessed to form a fixing groove for receiving the upper edge of the lower shell, and the depth of the fixing groove is at least equal to the thickness of the upper edge of the lower shell;
[0018] The sum of the thickness of the lower edge of the upper shell and the thickness of the upper edge of the lower shell is at most equal to the thickness of the upper shell.
[0019] Preferably, the upper shell and the lower shell have a regular square prism structure;
[0020] The connector is arranged in a ring structure, and the inner corner of the lower shell and the outer corner of the upper folded edge of the connector are mutually separated.
[0021] As can be seen from the above, the following beneficial effects can be obtained by applying the technical solution provided by this utility model:
[0022] First, the connector proposed in this utility model is an independent sheet metal unit with a relatively simple structure. It has lower processing requirements and fewer processing steps for sheet metal parts, which can simplify the processing steps and at the same time maintain the precision of the integrally formed connector.
[0023] Secondly, the connector proposed in this utility model has an anti-groove on its outer side. When the outer side and the inner side of the lower shell are filled with sealant, the adhesion between the sealant and the connector can be improved, further enhancing the waterproof performance.
[0024] Third, the movable stop waterproof structure proposed in this utility model can modify the existing upper and lower shell structure by selecting appropriate connectors. Since the connectors have a relatively simple structure and low cost, the modification cost can be greatly reduced. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0030] Traditional sheet metal parts are difficult to form an integral stop structure directly through injection molding or compression molding due to the material characteristics, which limits their waterproof performance. They usually have to rely on additional seals or complex welding processes to achieve waterproof function, but this method has the problems of high cost, complicated assembly and uneven glue distribution.
[0031] Example 1
[0032] like Figure 1 As shown, in order to solve the above problems, this embodiment proposes a connector 10, which includes a main structure 11 and a folded edge 12 arranged perpendicularly to each other, and the folded edge 12 is arranged to protrude outward; the horizontal height of the folded edge 12 is lower than the top horizontal height of the main structure 11.
[0033] Preferably, in this embodiment, the folded edge 12 is located at the bottom end of the main structure 11.
[0034] Preferably, in this embodiment, the connector 10 is an annular structure with an L-shaped longitudinal section; the connector 10 can also be a strip structure with an inverted T-shaped longitudinal section. Specifically, a suitable connector 10 structure can be selected according to the width of the shell structure that is combined with the connector 10.
[0035] Preferably, in this embodiment, the connector 10 is an integrally formed independent sheet metal unit.
[0036] In this embodiment, the connector 10 is configured as described above, which can be used to form a U-shaped groove with the subsequent shell or other shell-shaped structures to achieve the corresponding waterproof function. Moreover, the processing steps of this shape are relatively simple, which can simplify the processing while maintaining the high precision of the connector 10.
[0037] More specifically, the connection end of the main structure 11 with the folded edge 12 is recessed to form an anti-groove 13, and the bottom surface of the anti-groove 13 is a concave-convex surface.
[0038] Preferably, in this embodiment, the anti-groove 13 is used to increase the capacity of the sealant on the U-shaped groove, and the concave structure allows the sealant in the anti-groove 13 to have a right-angle deformation space with the sealant on the outside of the main structure 11, thus avoiding the possibility of the sealant sliding in the U-shaped groove.
[0039] In this embodiment, the concave-convex surface design can further increase the tightness of the bond between the sealant and the connector 10, and further improve the waterproofness of the connector 10 after it is combined with the shell structure.
[0040] Example 2
[0041] like Figure 2 and Figure 3 As shown, in order to solve the aforementioned problems, this embodiment proposes a movable stop waterproof structure, including the connector 10 of Embodiment 1, and also including a lower shell 30 and an upper shell 20; the top end of the lower shell 30 is an open end face; the connector 10 is built into the lower shell 30, and the outer contour of the folded edge 12 of the connector 10 is equal to the inner contour of the lower shell 30; a sealant is filled between the inner side of the connector 10 and the lower shell 30; the top ends of the upper shell 20 and the lower shell 30 are detachably connected.
[0042] Preferably, in this embodiment, if the lower shell 30 is a flat structure, a strip-shaped connector 10 is provided accordingly. When the lower shell 30 is a polygonal prism structure, the connector 10 is an annular structure, and the folded edge 12 of the connector 10 is arranged to abut against the inner side of the lower shell 30 outward.
[0043] Preferably, the connector 10 is built into the lower housing 30, but is located near the top edge of the lower housing 30.
[0044] Preferably, in this embodiment, the sealant is a cool-curing sealant. Preferably, but not limited to, silicone sealant is used in this embodiment.
[0045] In this embodiment, the main structure 11 of the connector 10, the folded edge 12 and the inner side of the lower shell 30 form a U-shaped groove. Silicone sealant is evenly injected along the U-shaped groove and forms a waterproof layer after curing.
[0046] More specifically, the lower shell 30 includes a limiting structure protruding from the inner side of the lower shell 30, the limiting structure supporting the folded edge 12 of the fixed connector 10.
[0047] Preferably, in this embodiment, the limiting structure is a strip structure, which is distributed in a ring around the inner side of the lower shell 30.
[0048] In this embodiment, since the outer contour of the folded edge 12 on the connector 10 is equal to the inner contour of the lower shell 30, the connector 10 is precisely slidably installed along the side height within the lower shell 30. The limiting structure formed by the protrusion ensures the installation height and stability of the connector 10 within the lower shell 30, which can guarantee the sealing performance of the subsequent sealant and the waterproof performance of the movable stop waterproof structure.
[0049] More specifically, the upper edge of the lower shell 30 and the lower edge of the upper shell 20 are both provided with through holes for external fasteners 40 to pass through and fix.
[0050] Preferably, in this embodiment, the through holes are circular and are evenly distributed along the upper edge of the lower shell 30 and the lower edge of the upper shell 20. At the same time, the positions of the through holes on the upper shell 20 and the positions of the through holes on the lower shell 30 should be aligned.
[0051] Preferably, in this embodiment, the external fastener 40 is a bolt, and the length of the bolt should be at least equal to the sum of the thickness of the upper edge of the lower shell 30 and the thickness of the lower edge of the upper shell 20.
[0052] Preferably, in this embodiment, the through hole may be provided with internal threads, and is fixed to the external fastener 40 by means of threaded connection.
[0053] In this embodiment, the cured seal effectively improves the waterproof performance inside the lower shell 30, and the detachable connection between the upper shell 20 and the lower shell 30 further enhances the overall integrity of the movable stop waterproof structure.
[0054] More specifically, the bottom end of the upper shell 20 is recessed to form a fixing groove for receiving the upper edge of the lower shell 30, and the depth of the fixing groove is at least equal to the thickness of the upper edge of the lower shell 30; the sum of the thickness of the lower edge of the upper shell 20 and the thickness of the upper edge of the lower shell 30 is at most equal to the thickness of the upper shell 20.
[0055] Preferably, in this embodiment, the depth of the fixing groove is exactly equal to the thickness of the upper edge of the lower shell 30, and the sum of the thickness of the lower edge of the upper shell 20 and the thickness of the upper edge of the lower shell 30 is exactly equal to the thickness of the upper shell 20.
[0056] Preferably, in this embodiment, the lower edge thickness of the upper shell 20 can be stacked outside the upper edge thickness of the lower shell 30 for detachable connection.
[0057] In this embodiment, the upper shell 20 and the lower shell 30 are assembled by overlapping the lower edge of the upper shell 20 and the upper edge of the lower shell 30 and connecting them with external fasteners 40, which can further improve the overall integrity of the movable stop waterproof structure.
[0058] More specifically, the upper shell 20 and the lower shell 30 are in the form of regular square prisms; the connector 10 is in the form of a ring structure, and the inner corner of the lower shell 30 and the outer corner of the upper folded edge 12 of the connector 10 are mutually separated.
[0059] Preferably, in this embodiment, the outer corner of the folded edge 12 on the connector 10 is rounded; the inner corner of the corresponding lower shell 30 is rounded.
[0060] In this embodiment, the gap-avoiding design can greatly improve the connection tightness between the upper folded edge 12 of the connector 10 and the inner side of the lower shell 30, and further improve the waterproofness of the seal.
[0061] In summary, Embodiments 1 and 2 propose a waterproof structure for a connector and movable stop. An independent sheet metal unit is installed at the junction of the upper and lower shells, with its two sides fixedly connected to the upper and lower shells respectively, forming a closed U-shaped glue groove. Since the cross-section of the independent sheet metal unit is a bent structure, including a vertical section and a horizontal section, the horizontal section extends outward to form the groove wall. The groove is filled with sealant, which, after curing, forms a waterproof barrier.
[0062] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
