Description

Technical Field

[0001] This utility model relates to the field of building material construction accessories technology, specifically to a pre-embedded plug. Background Technology

[0002] Some building materials have embedded parts with channels pre-embedded in them during the casting process, such as embedded pipes and nuts. To prevent concrete from entering the channels of these embedded parts during the casting process, rubber plugs are usually used to plug the channel ports before casting. The rubber plugs are then removed after the building material has solidified.

[0003] However, the existing rubber plugs used to seal the channel ports do not have any leverage points. Therefore, when it is necessary to remove the rubber plug, it is usually removed by force with a hard object. This can easily damage the rubber plug, making it unusable. Therefore, it needs to be improved. Utility Model Content

[0004] In order to solve at least one of the technical problems mentioned in the background art, the purpose of this utility model is to provide a pre-embedded plug.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0034] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0035] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” that indicate orientation or positional relationship are used only for the convenience of describing the embodiments and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0036] Example 1

[0037] See Figure 1-4 As shown, for the pouring of some building materials with embedded parts, such as using pipes as embedded parts, in order to prevent concrete from entering the channel of the embedded part during pouring, this embodiment provides an embedded part plug to seal the channel port of the embedded part, such as... Figure 4 As shown, the embedded parts can be seen in part M in the figure, and part M1 shows the channel of the embedded parts.

[0038] like Figure 1 As shown, the plug provided in this embodiment includes a plug body 1 and a force-bearing member 2. The following is a detailed description of each component:

[0039] like Figure 2As shown, the plug body 1 includes a base 12 and a plunger 11 fixedly connected to the base 12. Both the plunger 11 and the base 12 have elasticity. For example, both the base 12 and the plunger 11 are made of rubber. In addition, the base 12 and the plunger 11 are integrally molded structures, thus forming an integral rubber plug structure.

[0040] The plunger 11 is used to insert into the channel of the embedded part to seal it and prevent concrete from entering the channel. It is understood that the cross-sectional shape of the plunger 11 is adapted to the cross-sectional shape of the channel of the embedded part; for a circular channel, the plunger 11 is cylindrical.

[0041] The shape of the base 12 can be designed according to actual needs. For example, this embodiment shows a frustum-shaped connecting part 22.

[0042] In addition, such as Figure 2 As shown, an annular groove 121 is formed between the base 12 and the plunger 11, surrounding the plunger 11. The annular groove 121 is mainly used for the end of the embedded part to be inserted. Specifically, during sealing, as... Figure 4 As shown, the plunger 11 is inserted into the channel of the embedded part through the end of the embedded part. At the same time, the end of the embedded part is inserted into the annular groove 121. At this time, it is equivalent to forming two layers of sealing, the outer layer is the part of the peripheral wall of the annular groove 121 formed by the base 12 and adhering to the peripheral wall of the embedded part to form a section of sealing. The inner layer is the plunger 11 inserted into the channel to perform a section of sealing. This helps to improve the sealing effect.

[0043] It is worth noting that the design of the annular groove 121 has a more significant effect on some embedded parts with threads on the outer peripheral wall of the end. That is, the peripheral wall of the annular groove 121 can cover the threaded section on the outer peripheral wall of the end of the embedded part, thereby preventing concrete from adhering to the threads of the embedded part.

[0044] The design of the force-bearing component 2 is mainly to provide a force-bearing part for the entire plug, facilitating the removal of the plug by hand or tools when needed. Specifically:

[0045] The force-bearing component 2 is connected to the plug body 1, such as Figure 3 As shown, the force-bearing component 2 includes a connecting part 22 and a force-bearing part 21; the connecting part 22 is connected to the base 12, while the force-bearing part 21 is mainly for hand or tool gripping. The force-bearing part 21 protrudes at least partially from the outer surface of the plug body 1. When the plug body 1 is inserted into the pre-embedded part, the force-bearing part 21 is at least partially exposed to the outside for hand or tool gripping.

[0046] In some embodiments, the force-applying part 21 is located on the opposite side of the plunger 11; in other words, the force-applying part 21 and the plunger 11 are located on opposite sides of the base 12.

[0047] The specific structure of the force-bearing part 21 is such that the force-bearing part 21 forms a ring structure surrounding the force-bearing member 2, for example, as... Figure 3 As shown, the force-bearing part 21 has an arc-shaped pull ring structure, with its two ends fixed to the connecting part 22, thereby forming the ring structure between it and the connecting part 22, allowing a person or tool to insert and hold it; taking the removal of the plug by hand as an example, a person can insert their fingers into the ring and pull the pull ring to remove the plug.

[0048] In some embodiments, the force-bearing member 2 is made of a hard metal material, for example, the force-bearing member 2 is entirely made of iron.

[0049] Of course, in some alternative embodiments, the force-applying part 21 can also be a pull rope structure (not shown in the figure). That is, one or both ends of the pull rope are fixed to the connecting part 22, and the pull rope provides the force point for removing the plug.

[0050] The specific connection between the connecting part 22 and the plug body 1 can be as follows: the connecting part 22 is embedded in the plug body 1, for example, as... Figure 3 As shown, a groove 122 is provided on the connecting part 22, the connecting part 22 is embedded in the groove 122 and fixed by glue; or, when making the plug body 1, the connecting part 22 is directly embedded in the base 12 of the plug body 1.

[0051] Example 2

[0052] This embodiment further provides a pre-embedded plug based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that the connection method between the connecting part 22 and the plug body 1 is different. Specifically:

[0053] In this embodiment, as Figure 5-7 As shown, the plug also includes a connecting component 3, and the connecting part 22 is detachably connected to the plug body 1 via the connecting component 3.

[0054] Among them, such as Figure 5 As shown, the connecting component 3 includes a baffle 31 and a screw 32.

[0055] The baffle 31 is disposed in the annular groove 121; in some embodiments, the baffle 31 has an annular structure and can be embedded in the annular groove 121, and the plunger 11 can pass through the annular hole of the baffle 31.

[0056] The screws 32 are mainly used to connect the baffle 31 and the connecting part 22. The number of screws 32 can be one or more, preferably at least two, and they are distributed in a circumferential array along the annular baffle 31.

[0057] like Figure 5As shown, a first through hole 311 for screw 32 to pass through is provided on the baffle 31, and a second through hole 123 axially penetrating the base 12 is provided in the annular groove 121. The second through hole 123 corresponds to the first through hole 311 and is used for screw 32 to pass through. A screw hole 221 for screw 32 to be threaded is provided on the side of the connecting part 22 opposite to the force part 21.

[0058] During assembly, such as Figure 6 As shown, the baffle 31 is placed in the annular groove 121, and the plunger 11 passes through the annular hole of the baffle 31; the connecting part 22 is embedded in the groove 122 of the base 12, and aligned with the first through hole 311 and the second through hole 123; then the screw 32 is screwed from the annular groove 121 through the first through hole 311 and the second through hole 123 and into the screw hole 221, and threadedly connected to the connecting part 22, thus assembling the plug. Figure 7 The state shown.

[0059] Compared with the connection method of the connection part 22 and the plug body 1 provided in Embodiment 1, the connection method of the connection part 22 and the plug body 1 provided in this embodiment makes it more difficult for the force-bearing member 2 to detach from the plug body 1 when the plug is pulled out.

[0060] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
