Description

Technical Field

[0001] The utility model relates to the technical field of sleeves, in particular to a sleeve for electrical engineering installation positioning. Background Technique

[0002] Electrical engineering is a core and key discipline in the field of modern science and technology. The traditional definition of electrical engineering is the sum of related disciplines used to create electrical and electronic systems. During the construction process of electrical engineering, positioning and installation sleeves for electrical engineering are required to pre-embed pipelines. The power supply wires usually start from the bottom layer and are connected into the building, and then access each floor through the floor slabs of each floor. According to relevant electrical installation specifications, the outer wall of electrical cables must be sheathed with sleeves, that is, electrical sleeves must be pre-embedded while concrete is being constructed.

[0003] In view of the limitation of the length of the installation sleeve, when it is necessary to connect two sleeves, there are currently some challenges. In conventional operations, if only tape is used to wrap the connection part, the sealing effect will be poor and it is easy to loosen, which will undoubtedly affect the stability and safety of the system. On the other hand, although the method of capacitor fusion connection can provide stronger connection strength, this method will significantly reduce the construction efficiency and increase the workload of the staff. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 As shown, a casing for electrical engineering installation positioning includes a first sleeve pipe 1 and a second sleeve pipe 5 connected to the first sleeve pipe 1. On one side of the surface of the first sleeve pipe 1, a sub-joint 2 is provided. On one side of the surface of the second sleeve pipe 5, a mother-joint 8 is provided. It further includes:

[0022] A connection mechanism 6 arranged in the inner cavity of the first sleeve pipe 1 for connecting with the second sleeve pipe 5, and an insertion pipe mechanism 7 cooperating with the connection mechanism 6 is arranged in the inner cavity of the second sleeve pipe 5.

[0023] When the first sleeve pipe 1 and the second sleeve pipe 5 of the present utility model are connected, under the action of the connection mechanism 6 and the insertion pipe mechanism 7, the first sleeve pipe 1 and the second sleeve pipe 5 can be preliminarily connected. And under the action of the glue in the connection mechanism 6, the connection strength between the sub-joint 2 and the mother-joint 8 is improved, the connection difficulty between the first sleeve pipe 1 and the second sleeve pipe 5 is reduced, and thus it is convenient for the staff to construct.

[0024] The connection mechanism 6 includes a plurality of first fixing feet 61 fixed at one end of the inner cavity of the first sleeve pipe 1 and a plurality of glue outlet holes 65 opened on the surface of the sub-joint 2. A plugging pipe 62 is fixed on the surface of the first fixing foot 61. A glue pushing head 63 for plugging the glue is slidably arranged in the inner cavity of the plugging pipe 62. One side of the surface of the plugging pipe 62 is communicated with a glue conveying pipe 64, and the other end of the glue conveying pipe 64 is communicated with the surface of the glue outlet hole 65. In this embodiment, through the settings of the first fixing feet 61, the plugging pipe 62, the glue pushing head 63, the glue conveying pipe 64 and the glue outlet holes 65, under the action of the first fixing feet 61, a plurality of plugging pipes 62 are arranged in the inner cavity of the first sleeve pipe 1. When the glue pushing head 63 is extruded, the glue on one side of the glue pushing head 63 will flow in the glue conveying pipe 64 and flow out from the glue outlet holes 65.

[0025] A plurality of first fixing feet 61 are fixedly arranged in a circular array at the inner cavity of the first sleeve pipe 1. In this embodiment, through this setting, a plurality of plugging pipes 62 are arranged equidistantly and circularly in the inner cavity of the first sleeve pipe 1. Thus, when cooperating with the insertion pipe mechanism 7 to work, the acting force is evenly dispersed on the surface of the first sleeve pipe 1.

[0026] The intubation mechanism 7 includes several second fixing feet 71 fixed to the inner cavity of the second sleeve tube 5. The surface of the second fixing feet 71 is fixed with an insertion tube 72. The outer diameter of the insertion tube 72 is equal to the inner diameter of the insertion line tube 62. In this embodiment, through the arrangement of the second fixing feet 71 and the insertion tube 72, under the connection of the second fixing feet 71, the insertion tube 72 can enter the insertion line tube 62 following the second fixing feet 71.

[0027] The female connector 8 is designed as a hollow truncated cone shape, and the shape of the male connector 2 is complementary to the shape of the female connector 8. In this embodiment, through this arrangement, it is convenient for the connection between the female connector 8 and the male connector 2, and the connection stability between the female connector 8 and the male connector 2 is improved.

[0028] One end of the second sleeve tube 5 is engaged with a connecting tube 4, and one side of the surface of the connecting tube 4 is fixed with a protection tube 3. In this embodiment, through the arrangement of the connecting tube 4 and the protection tube 3, protection is provided for the intubation mechanism 7 to prevent the insertion tube 72 from breaking when the intubation mechanism 7 is moved or not in use.

[0029] Working principle: During use, the staff can insert the wire into the first sleeve tube 1. Then, under the action of the first sleeve tube 1, the wire is protected and positioned. And when the wire passes through between several insertion line tubes 62, due to the blocking of the insertion line tubes 62, the wire can be prevented from completely adhering to the inner cavity of the first sleeve tube 1, thereby avoiding the influence on the heat dissipation of the wire due to the adhesion between the first sleeve tube 1 and the wire. If the length of the first sleeve tube 1 cannot support the length of the wire, the staff can take out the second sleeve tube 5 with the connecting tube 4 and rotate the connecting tube 4 relative to the second sleeve tube 5, so that the connecting tube 4 disengages from the second sleeve tube 5. Then the staff can insert the exposed insertion tube 72 into the insertion line tube 62. After the insertion tube 72 completely slides into the insertion line tube 62, the male connector 2 and the female connector 8 are also connected. And when the insertion tube 72 slides into the insertion line tube 62, the insertion tube 72 can make the glue pushing head 63 slide in the inner cavity of the insertion line tube 62. Then, under the extrusion of the glue pushing head 63, the glue in the inner cavity of the insertion line tube 62 flows out from the glue outlet hole 65. Under the action of the glue, the connection ability between the male connector 2 and the female connector 8 is improved, and thus the connection stability between the first sleeve tube 1 and the second sleeve tube 5 is improved.
