Description

Technical Field

[0001] This utility model relates to the field of sleeve technology, specifically to a pre-embedded positioning sleeve for electrical installation engineering. Background Technology

[0002] Pre-embedded positioning sleeves used in electrical installation projects are pipes that are pre-installed within the formwork before concrete pouring to provide space for cables, conduits, or other electrical installations. These sleeves are typically made of metal or plastic, possessing sufficient strength and durability to withstand various stresses during construction and protecting the internal wires and cables from external environmental influences.

[0003] Currently used pre-embedded positioning sleeves are typically standardized in size; however, different construction sites and conditions have varying requirements. In some cases, such as when encountering thicker or wider walls or floor slabs, standard-sized sleeves may not meet the needs, requiring additional customization. Such adjustments not only extend the construction period but also increase project costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pre-embedded positioning sleeve for electrical installation engineering, the length of which can be adjusted as needed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-embedded positioning sleeve for electrical installation engineering, comprising an inner tube, with sliding components slidably connected to the outer walls of both ends of the inner tube, and an outer tube connected to the other end of each of the two sliding components, with a connecting ring fixedly connected to the ends of the two outer tubes that are far apart from each other.

[0006] Furthermore, a support ring is fixedly connected to the middle of the outer wall of the inner tube, and two sliding components and two connecting rings are located on both sides of the support ring.

[0007] Furthermore, the sliding assembly includes several sliders, and several grooves are provided on the outer walls of both ends of the outer tube. The outer walls of the sliders are slidably connected to the inner walls of the grooves.

[0008] Furthermore, several slots are provided on one side of several sliding grooves, and the outer walls of several sliders are slidably connected to the inner walls of several slots, and the length of the slider is less than the length of the slot.

[0009] Furthermore, a No. 2 thread is provided on the side of the slider away from the outer tube, and a No. 1 thread is provided on the inner wall of the slot. The No. 2 thread matches the No. 1 thread, and the slider and the slot are connected by the No. 2 thread and the No. 1 thread.

[0010] Furthermore, sealing rings are fixedly connected to the outer walls of both ends of the inner tube, and the outer walls of the two sealing rings are slidably connected to the inner walls of the two outer tubes respectively.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This type of pre-embedded positioning sleeve for electrical installation projects, by setting outer tubes and sliding components at both ends of the inner tube, allows the outer tube to be stretched outward during construction according to construction needs, thereby increasing the overall length to adapt to more installation scenarios.

[0013] 2. This type of pre-embedded positioning sleeve for electrical installation projects has a connecting ring at the end of the outer pipe. Holes can be drilled on the connecting ring as needed, so that the connecting ring can be easily fixed to the external flange or other objects. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1-4 An embedded positioning sleeve for electrical installation engineering includes an inner tube 1, with sliding components slidably connected to the outer walls of both ends of the inner tube 1, and an outer tube 3 connected to the other end of each of the two sliding components, with a connecting ring 4 fixedly connected to the ends of the two outer tubes 3 that are far apart from each other.

[0021] like Figures 1 to 4As shown, when using the pre-embedded positioning sleeve for electrical installation engineering in this utility model, if the length of the inner tube 1 alone is insufficient to meet the construction requirements, one or two outer tubes 3 can be pulled out towards the end away from the inner tube 1 by means of the sliding component before fixing the inner tube 1 at the pre-embedded location, thereby changing the total length between the inner tube 1 and the outer tubes 3 to accommodate more different sizes, which is convenient, quick and easy to operate.

[0022] It should be noted that by setting the connecting ring 4, holes can be drilled on the connecting ring 4 as needed, so that the connecting ring 4 can be easily fixed to the external flange or other objects.

[0023] As a preferred embodiment of this utility model, a support ring 2 is fixedly connected to the middle of the outer wall of the inner tube 1, and two sliding components and two connecting rings 4 are located on both sides of the support ring 2.

[0024] More specifically, by setting the support ring 2, the support and stress in the middle of the inner tube 1 can be increased, reducing the probability of damage or bending and collapse of the inner tube 1.

[0025] As a preferred embodiment of the present invention, the sliding assembly includes a plurality of sliders 9, and the outer walls at both ends of the outer tube 3 are provided with a plurality of grooves 5, and the outer walls of the plurality of sliders 9 are slidably connected to the inner walls of the plurality of grooves 5 respectively.

[0026] More specifically, by setting up slider 9 and slide 5, it is easier to move the outer tube 3 outside the inner tube 1; secondly, it is also possible to restrict the movement trajectory of the outer tube 3 when it moves, so that the outer tube 3 can only move in a specific direction and will not tilt.

[0027] As a preferred embodiment of this utility model, a plurality of slots 6 are provided on one side of a plurality of sliding grooves 5, and the outer walls of a plurality of sliders 9 are slidably connected to the inner walls of a plurality of slots 6 respectively, and the length of the slider 9 is less than the length of the slot 6.

[0028] More specifically, by setting the slot 6, when the outer tube 3 is moved to a certain length by the slider 9, the outer tube 3 can be locked in the slot 6 by simply rotating it to one side, thereby increasing the stability of the outer tube 3 and reducing the possibility of the outer tube 3 shaking or retracting itself during construction.

[0029] As a preferred embodiment of this utility model, the slider 9 is provided with a second thread 10 on the side away from the outer tube 3, and the inner wall of the slot 6 is provided with a first thread 7. The second thread 10 and the first thread 7 are matched, and the slider 9 and the slot 6 are connected by the second thread 10 and the first thread 7.

[0030] More specifically, by setting the second thread 10 and the first thread 7, the slider 9 can be locked through the threaded connection of the second thread 10 and the first thread 7 during the process of rotating it into the slot 6, which further increases stability and reduces the probability of shaking.

[0031] As a preferred embodiment of this utility model, sealing rings 8 are fixedly connected to the outer walls of both ends of the inner tube 1, and the outer walls of the two sealing rings 8 are slidably connected to the inner walls of the two outer tubes 3 respectively.

[0032] More specifically, by setting the sealing ring 8, the sealing performance at the connection between the inner pipe 1 and the outer pipe 3 can be improved both when the outer pipe 3 is extended and when it is not extended, thereby reducing the probability that external soil or concrete will enter the inner pipe 1 and the outer pipe 3 after backfilling.

[0033] Finally, it should be noted that although soil or concrete may block the chute 5, the slot 6, and the No. 1 thread 7 after backfilling, the inner pipe 1 and the outer pipe 3 will not be replaced after backfilling unless they are damaged. Therefore, the connection between the inner pipe 1 and the outer pipe 3 will not be affected.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
