Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, and particularly relates to a line threading sleeve for electrical engineering. Background Art

[0002] When wiring electrical engineering equipment, it is often necessary to pass cables through the walls of buildings to achieve the electrical connection of electrical engineering equipment across buildings. In order to prevent the thermal expansion and contraction of the cement in the building walls from cracking the outer skin of the cables and causing cable leakage, it is often necessary to pre-embed a line threading sleeve for electrical engineering in the wall, and then pass the cables through the line threading sleeve for electrical engineering for wiring. The line threading sleeve for electrical engineering can effectively protect the cables passing through the wall.

[0003] For example, the application number: CN202222684623.8. The utility model discloses a line threading sleeve, which includes a mounting plate, a connecting plate, a sleeve and a support rod. Connecting grooves are opened on both sides of the mounting plate, a circular hole is opened in the center of the mounting plate, and limiting blocks are symmetrically and fixedly arranged on the mounting plate. The connecting plate is horizontally inserted into the connecting grooves of two adjacent mounting plates, the sleeve is inserted into the circular hole, pipe caps are sleeved at both ends of the sleeve, two support rods are symmetrically and obliquely arranged on both sides of the sleeve, an arc-shaped clamping block is fixedly arranged at the upper end of the support rod, and a convex block is arranged at the lower end of the support rod. The convex block is inserted into the inner side of the limiting block. In the utility model, the mounting plates can be spliced into a whole according to the number of sleeves. The two sides of the sleeve are obliquely supported by support rods, which can effectively prevent the sleeve body from deforming due to force.

It is necessary to insert the connecting plate and then tighten the bolts to connect and install the mounting plates, which reduces the connection efficiency. Moreover, the inclined support rods are used to support the sleeve, increasing the occupied area. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] As shown Figures 1 to 3 in the figure, a wire threading sleeve for electrical engineering provided by the utility model includes a first mounting plate 1 and a sleeve body 2. A second mounting plate 3 is arranged on the right side of the first mounting plate 1. The inner walls of the first mounting plate 1 and the second mounting plate 3 are both slidably connected to the bottom surface of the sleeve body 2. A limiting ring 4 is sleeved on the top of the sleeve body 2. Support half-rings 5 are arranged on both sides of the bottom of the limiting ring 4. Vertical support rods 6 are fixedly connected to the bottom of the support half-rings 5. A plurality of vertical support rods 6 are arranged and are equally spaced in an arc shape. The bottoms of the vertical support rods 6 are fixedly connected to the tops of the first mounting plate 1 and the second mounting plate 3. Plug connectors 7 are fixedly connected to both sides of the left side of the first mounting plate 1 and both sides of the left side of the second mounting plate 3. Plug slots 8 are formed on both sides of the right side of the first mounting plate 1 and both sides of the right side of the second mounting plate 3. The plug connectors 7 are inserted into the plug slots 8. Limiting mechanisms 9 are arranged on both sides of the right side of the top of the first mounting plate 1 and both sides of the right side of the top of the second mounting plate 3.

[0023] Referring Figure 3 to the figure, the limiting mechanism 9 includes a limiting baffle 91, a limiting slider 92 and a limiting slot 93. The limiting baffle 91 is located on both sides of the right side of the top of the first mounting plate 1 and both sides of the right side of the top of the second mounting plate 3. The tops of the limiting sliders 92 are fixedly connected to both sides of the left bottom of the limiting baffle 91. The limiting slots 93 are formed on both sides of the right side of the top of the first mounting plate 1 and both sides of the right side of the top of the second mounting plate 3. The inner wall of the limiting slot 93 is slidably connected to the surface of the limiting slider 92. The cross-sections of the limiting slot 93 and the limiting slider 92 are both T-shaped.

[0024] As a technical optimization scheme of the utility model, by arranging the limiting mechanism 9, after the user splices and installs the first mounting plate 1 and the second mounting plate 3, the user can directly move the limiting baffle 91 to the top of the plug connector 7 to the right. Due to the cross-sections of the limiting slider 92 and the limiting slot 93 being both T-shaped, the limiting baffle 91 is limited upward, thereby limiting the plug connector 7 upward and preventing the plug connector 7 from disengaging from the plug slot 8, improving the installation strength.

[0025] Referring Figure 3 to the figure, an anti-slip strip 10 is fixedly connected to the top of the limiting baffle 91. A plurality of anti-slip strips 10 are arranged and are equally spaced.

[0026] As a technical optimization scheme of the utility model, by arranging the anti-slip strip 10, when the user needs to push the limiting baffle 91 to move, the user's hand can contact the limiting baffle 91 through the anti-slip strip 10, greatly improving the friction between the user's hand and the limiting baffle 91 and preventing the situation of slipping due to too low friction.

[0027] Reference Figure 1 , a cover 11 is sleeved on the top of the surface of the casing body 2, and the cover 11 is made of PP plastic.

[0028] As a technical optimization scheme of the utility model, by setting the cover 11, when the cable is not passed through the casing body 2, the user can use the cover 11 to sleeve on the top of the surface of the casing body 2, so as to seal the top of the casing body 2 and prevent dust from entering the inside of the casing body 2. Then, by using the characteristic of low cost of PP plastic, the use cost is reduced.

[0029] Reference Figure 3 , a spring 12 is fixedly connected to the left side of the limit slider 92, and one end of the spring 12 away from the limit slider 92 is fixedly connected to the left side of the inner wall of the limit groove 93.

[0030] As a technical optimization scheme of the utility model, by setting the spring 12, when the user needs to insert the plug-in part 7 into the plug-in slot 8 and push the limit baffle 91 to the left, the spring 12 will be squeezed by the limit slider 92, so that the spring 12 generates a resilience force. When the plug-in part 7 is completely inserted into the plug-in slot 8, the limit baffle 91 will be above the horizontal plane of the plug-in part 7. At this time, the elastic force of the spring 12 can be released, so that the spring 12 pushes the limit baffle 91 to move to the right to the top of the plug-in part 7, improving the use fluency.

[0031] Reference Figure 3 , positioning magnets 13 are magnetically adsorbed on both sides of the right side of the limit baffle 91, and the bottom of the positioning magnets 13 is fixedly connected to both sides of the top right side of the first mounting plate 1 and both sides of the top right side of the second mounting plate 3.

[0032] As a technical optimization scheme of the utility model, by setting the positioning magnets 13, after the user moves the limit baffle 91 to the right, the left side of the positioning magnet 13 will contact both sides of the right side of the limit baffle 91, and then the positioning magnet 13 will adsorb and position the limit baffle 91, so that the limit baffle 91 is more stable during use.

[0033] Reference Figure 3 , dust-proof plates 14 are fixedly connected to both sides of the left side of the limit baffle 91, and the dust-proof plates 14 are located at the top of the limit groove 93.

[0034] As a technical optimization solution of the present utility model, by providing a dust-proof plate 14, since the dust-proof plate 14 is located at the top of the limit groove 93, when the user pushes the limit baffle 91 to move, the dust-proof plate 14 will be driven to move synchronously. At this time, the dust-proof plate 14 can block the top of the limit groove 93 to prevent foreign objects from entering the inside of the limit groove 93 and causing the sliding connection between the limit groove 93 and the limit slider 92 to jam.

[0035] The working principle and usage process of the present utility model: After the user inserts the sleeve body 2 into the first mounting plate 1 and the second mounting plate 3, the support semi-ring 5 is used to support the limit ring 4, so that the sleeve body 2 is supported. During the use of the support semi-ring 5, due to the perpendicularity of the vertical support rod 6, the occupied area can be reduced. And when the user needs to install the first mounting plate 1 and the second mounting plate 3, the user can directly vertically insert the plug-in member 7 on the second mounting plate 3 into the inside of the plug-in groove 8, so as to quickly splice and install the first mounting plate 1 and the second mounting plate 3. Then the user can directly move the limit baffle 91 to the right to the top of the plug-in member 7. Since the cross-sections of the limit slider 92 and the limit groove 93 are both T-shaped, the limit baffle 91 is limited upward, so as to limit the plug-in member 7 upward and prevent the plug-in member 7 from disengaging from the plug-in groove 8, improving the installation strength and being convenient for assembly and reducing the occupied area.

[0036] In summary: For this electrical engineering line through sleeve, by providing the vertical support rod 6 and using the perpendicularity of the vertical support rod 6, the occupied area can be reduced. The plug-in member 7 on the second mounting plate 3 is vertically inserted into the inside of the plug-in groove 8, so as to quickly splice and install the first mounting plate 1 and the second mounting plate 3, solving the problem that the connection between the mounting plates is relatively cumbersome. It is necessary to insert a connecting plate and then tighten the bolts to connect and install the mounting plates, thereby reducing the connection efficiency, and using an inclined support rod to support the sleeve, increasing the occupied area.
