Abstract
Description
Technical Field
[0001] This application belongs to the technical field of rubber parts, and in particular relates to a combined rubber plug used in aluminum alloy doors and windows. Background Technology
[0002] Generally, aluminum alloy doors and windows are made of aluminum profiles. Rubber plugs can be used at the ends of the aluminum profiles to achieve the following functions: First, cover and protect the relatively sharp ends of the aluminum profiles to protect both the aluminum profiles themselves and the operators. Secondly, when aluminum profiles are installed in window and door openings, the aforementioned rubber plugs can remain in place, serving as elastic clamps to hold the sides of the window and door openings together. This provides the aluminum profiles with a preliminary positioning function, ensuring that subsequent screwing and bonding operations are more convenient and precise.
[0003] For example, Chinese utility model patent with authorization announcement number CN202769261U and authorization announcement date of March 6, 2013 discloses an aluminum alloy plug, whose main structural components include: plug body, mounting groove, plug mounting structure, connecting groove, connecting hole, and rubber buffer pad.
[0004] The advantages of the plug in this utility model patent are: it is not afraid of scratches caused by collisions and abrasions, it is not easy to damage other objects, and it has a simple structure and low cost.
[0005] However, in actual use, this plug has at least one obvious problem of limited functionality. Its main functions are the two mentioned above: protecting the aluminum alloy parts and blocking the window and door openings. Therefore, its practicality is relatively low. Utility Model Content
[0006] This application provides a combined rubber plug for use in aluminum alloy doors and windows. The technical problem to be solved is: how to make the rubber plug for aluminum profiles have relatively rich functions and high practicality.
[0007] The technical solution adopted by this application to solve the above problems is: a combined rubber plug for use on aluminum alloy doors and windows, the structure of which includes a grooved plug block unit disposed on the end face of the aluminum profile, a protruding plug block unit disposed on the same end face of the aluminum profile and used to insert into the grooved plug block unit on another aluminum profile, and an installation and fixing groove disposed on the grooved plug block unit and the protruding plug block unit and used to insert into and engage the outer side plate of the aluminum profile.
[0008] A further preferred technical solution is that the grooved plug block unit includes a first block having the mounting and fixing groove, and a side groove disposed on the first block, located outside the end face area of the aluminum profile, and used for inserting the protruding plug block unit onto another aluminum profile.
[0009] A further preferred technical solution is that the protruding plug block unit includes a second block having the mounting and fixing groove, and a side protruding block disposed on the second block, located outside the end face area of the aluminum profile, and used to insert into the side groove on another aluminum profile.
[0010] A further preferred technical solution is that: the side of the first block and / or the second block is also provided with an L-shaped protrusion for engaging the inner side plate of the aluminum profile.
[0011] A further preferred technical solution is that: the exposed end faces of the first block and / or the second block are also provided with strip-shaped protrusions for clamping door and window openings.
[0012] A further preferred technical solution is that: the inner end faces of the first block and the second block are also provided with side connecting grooves for engaging and fixing the additional functional plate.
[0013] A further preferred technical solution is that the side connecting groove is connected to the mounting and fixing groove.
[0014] A further preferred technical solution is that the L-shaped protrusion is also provided with a protrusion for clamping the elastic plate.
[0015] A further preferred technical solution is that: at the mounting and fixing groove, the thickness of both the grooved plug block unit and the protruding plug block unit is ≥8mm.
[0016] A further preferred technical solution is that the first block and / or the second block are further provided with hemispherical protrusions for clamping the elastic plate.
[0017] The beneficial effects of this application include at least the following two points.
[0018] First, in addition to the two basic functions of protecting the aluminum profile and blocking the door and window openings, this combination rubber plug also has the function of interlocking and locking, which makes the two aluminum profiles relatively fixed when used together.
[0019] Secondly, this combined rubber plug also has the additional functions of fixing and installing auxiliary functional plates and blocking and limiting elastic plates. Attached Figure Description

[0032] The following description is merely a preferred embodiment of this application and is not intended to limit the scope of this application.
[0033] like Figures 1-10As shown, a combined rubber plug for use on aluminum alloy doors and windows includes a grooved plug block unit 1 disposed on the end face of an aluminum profile a, a protruding plug block unit 2 disposed on the same end face of the aluminum profile a and used to insert into the grooved plug block unit 1 on another aluminum profile a, and an installation and fixing groove 3 disposed on the grooved plug block unit 1 and the protruding plug block unit 2 and used to insert into and engage the outer side plate a-1 of the aluminum profile.
[0034] In this embodiment, the grooved plug block unit 1 and its mounting groove 3 are integrally formed, serving as the "female end" of the combined rubber plug. The protruding plug block unit 2 and its mounting groove 3 are also integrally formed, serving as the "male end" of the combined rubber plug. The material of the combined rubber plug is EPDM rubber, silicone rubber, or nitrile rubber.
[0035] On the other hand, the general method of using this combined rubber plug is as follows: First, at least two of the combined rubber plugs, two aluminum profiles a, and two panels e together form a complete aluminum alloy component; Second, the "female end" and "male end" of the same combined rubber plug are set on the same end face of the aforementioned aluminum alloy component; Third, the relative positions of two adjacent aluminum alloy components can be initially fixed by connecting the "female end" of one component to the "male end" of the other. See the appendix for details. Figure 7 and 8 .
[0036] The main body of both the grooved plug block unit 1 and the protruding plug block unit 2 is a cuboid. The mounting and fixing groove 3 is formed on three adjacent surfaces of the grooved plug block unit 1 and the protruding plug block unit 2, so as to be inserted into the outer side plate a-1 of the aluminum profile, and thus fully fixed on the aluminum profile a.
[0037] The width of the mounting groove 3 is equal to the width of the grooved plug block unit 1 and the protruding plug block unit 2; the depth of the mounting groove 3 is slightly less than the thickness of the grooved plug block unit 1 and the protruding plug block unit 2. For details, please refer to the attached diagram. Figure 2 .
[0038] Finally, it should also be noted that: First, when the combined rubber plug is used correctly, the mounting groove 3 faces inward and is not visible. Secondly, this combined rubber plug can partially cover the relatively sharp end face on the aluminum profile a, thus providing end face protection. Third, the combined rubber plug protrudes appropriately on the end face of the aluminum alloy component, so when the aluminum alloy component is embedded in the door / window opening b, it can elastically clamp the side of the door / window opening b, providing a preliminary fixing effect for the aluminum alloy component.
[0039] The grooved plug block unit 1 includes a first block 101 with the mounting and fixing groove 3, and a side groove 102 disposed on the first block 101, located outside the end face area of the aluminum profile a, and used for inserting into another aluminum profile a.
[0040] In this embodiment, the side groove 102 is a through groove in the thickness direction on the first block 101, and its general cross-sectional shape is rectangular.
[0041] The protruding plug block unit 2 includes a second block 201 with the mounting and fixing groove 3, and a side protruding block 202 disposed on the second block 201, located outside the end face area of the aluminum profile a, and used to insert into the side groove 102 on another aluminum profile a.
[0042] In this embodiment, the mutual insertion relationship between the "male end" and the "female end" refers to the engagement and appropriate interference fit between the side groove 102 and the side protrusion 202. When the combined rubber plug is correctly installed on the same end face of the aluminum alloy assembly, the exposed surface of the first block 101 is flush with the exposed surface of the second block 201.
[0043] Specifically, when the two aluminum alloy components are correctly spliced, one of their respective aluminum profiles abuts against each other. At this time, the side protrusion 202 also has the effect of being inserted into the side groove 102. Generally, in the insertion direction of the side protrusion 202, the difference between its protrusion dimension and the concave dimension of the side groove 102 is controlled within 4mm.
[0044] The first block 101 and / or the second block 201 are also provided with L-shaped protrusions 4 for engaging the inner side plate a-2 of the aluminum profile.
[0045] In this embodiment, both the first block 101 and the second block 201 are provided with two L-shaped protrusions 4, and as shown in the attached figure. Figure 3 As shown, one is set on the left and one on the right.
[0046] Furthermore, in the thickness direction of the first block 101 and the second block 201, the size of the L-shaped protrusion 4 is the same as the former two, and the L-shaped protrusion 4 is integrally formed with the first block 101 and the second block 201.
[0047] Without considering the mounting and fixing groove 3, the overall structure consisting of the first block 101, the side groove 102 and the two L-shaped protrusions 4 is a body with a constant cross section, and the second block 201, the side protrusions 202 and the two L-shaped protrusions 4 are similar.
[0048] Specifically, the L-shaped protrusion 4 and the first block 101, and the L-shaped protrusion 4 and the second block 201 are used to fully clamp the inner side plate a-2 of the aluminum profile to prevent the combined rubber plug from falling off. The inner side plate a-2 of the aluminum profile is the invisible part of the aluminum alloy component during normal use.
[0049] In addition, the L-shaped protrusion 4 can also abut against the inner side of the outer side plate a-1 of the aluminum profile and the inner side of the panel e, thereby further improving the structural stability of the entire aluminum alloy assembly.
[0050] The exposed end faces of the first block 101 and / or the second block 201 are also provided with strip-shaped protrusions 5 for clamping the door and window openings b.
[0051] In this embodiment, the strip-shaped protrusion 5 and the mounting groove 3 are respectively disposed on two opposite surfaces of the first block 101, and the same applies to the second block 201.
[0052] The strip-shaped protrusion 5 is generally rectangular in shape, and its length is equal to or slightly less than the length of the first block 101 and / or the second block 201.
[0053] The inner end faces of the first block 101 and the second block 201 are also provided with side connecting grooves 6 for engaging and fixing the additional function plate c.
[0054] In this embodiment, a further structural optimization of the aluminum alloy component is as follows: an additional functional panel c is provided between the two panels e. The panels e are decorative panels, typically made of plastic or wood, while the additional functional panel c can be an insulation board, soundproof board, or fireproof board.
[0055] Specifically, in the aluminum alloy component, its length is equal to the length of the aluminum profile a and the length of the panel e, while the length of the additional functional plate c is relatively small. This is because the additional functional plate c needs to obtain a limiting effect at both ends of its length direction at the side connecting groove 6 to prevent it from sliding out and falling from the aluminum alloy component.
[0056] Furthermore, the term "side-connecting" in the side-connecting groove 6 refers to the fact that its groove openings are distributed on the inner end faces and sides of the first block 101 and the second block 201, as detailed in the appendix. Figure 2 .
[0057] The side connecting groove 6 connects to the mounting and fixing groove 3.
[0058] In this embodiment, the side connecting groove 6 connects to the mounting and fixing groove 3, so that the upper and lower sides of the additional function plate c can be pressed onto the two aluminum profiles a respectively, thereby improving the installation stability of the additional function plate c.
[0059] For details, see attached. Figure 3 As shown, the additional functional plate c abuts against the inner side of the outer side plate a-1 of the aluminum profile, and its thickness corresponds to the width of the side connecting groove 6. Therefore, the additional functional plate c can be completely fixed in principle.
[0060] The L-shaped protrusion 4 is also provided with a protrusion 7 for clamping the elastic plate d.
[0061] In this embodiment, a further structural optimization scheme for the above-mentioned aluminum alloy component is as follows: an elastic plate d is provided between the additional functional plate c and each panel e. The latter is made of foam board, and its main function is to fully reinforce the panel e and the additional functional plate c in the thickness direction of the aluminum alloy component, so as to prevent the panel e from easily undergoing concave deformation.
[0062] At this time, along the length of the elastic plate d, the first block 101 and the second block 201 in a certain area, as well as the L-shaped protrusion 4 in a certain area, can all block and limit it, while the protrusion 7 can further enhance the blocking and limiting strength.
[0063] At the mounting groove 3, the thickness f of both the grooved plug block unit 1 and the protruding plug block unit 2 is ≥8mm.
[0064] In this embodiment, the groove depth of the mounting groove 3 should not be too large to avoid the aluminum profile a breaking the grooved plug block unit 1 and the protruding plug block unit 2 into two pieces. This is the reason for setting the minimum value of the thickness f.
[0065] The first block 101 and / or the second block 201 are also provided with hemispherical protrusions 8 for clamping the elastic plate d.
[0066] In this embodiment, the hemispherical protrusion 8 and the protruding block 7 have the same function: to fully clamp the relatively elastic plate d, so as to prevent the aluminum alloy component from shaking and shifting inside the entire component during use.
[0067] Finally, it should be noted that: First, Appendix Figure 7 and 8The principle of using the combined rubber plugs in the two cases is essentially the same. The former is used when four aluminum alloy components are used together to form a door and window frame, while the latter is used, for example, when the top position inside the door and window opening b requires two different colored decorative panels, i.e., two types of panels e. Secondly, this combination rubber plug cannot be used as the only way to fix aluminum alloy components. The latter can also be fully fixed in the door and window opening b by screwing and / or bonding.
[0068] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this application. These are non-inventive modifications and are protected by patent law as long as they are within the scope of the claims of this application.
