Description

Technical Field

[0001] This utility model belongs to the field of junction boxes, specifically relating to the structure of an 86-type junction box. Background Technology

[0002] A cooling tower junction box is a device used to improve the efficiency of a cooling tower. It lowers the temperature of the air entering the cooling tower by pre-cooling the outside air, thereby improving cooling efficiency, saving energy, and reducing operating costs.

[0003] Most existing 86-type junction boxes have a relatively integrated fixed structure, which means that a single junction box is often suitable for a single wiring installation. However, in actual use, different environments require different numbers of wiring installations, so usually one or more junction boxes are needed to install the wiring. When the integrated fixed structure of the 86-type junction box is used to install different numbers of cable trays, it is often difficult to assemble and splice the single junction box according to the different numbers of cable trays.

[0004] Therefore, to address the problem that existing junction boxes are difficult to quickly assemble into multiple rows of junction boxes according to different wiring requirements, the 86-type junction box structure was developed. By adding a quick-assembly structure and a splicing fixing structure to the 86-type junction box, a single junction box can be quickly and stably assembled according to different wiring installation requirements, thus making it suitable for different wiring installation needs.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of an 86-type junction box structure, including a junction box body 1, an extension frame 4, a connecting baffle 3, and a cover plate 2. Openings 5 ​​are provided at both the left and right ends of the junction box body 1. A splicing plate 12 is fixedly connected to the inner wall of the rear end of the left opening 5 of the junction box body 1. Three sets of second positioning posts 11, evenly distributed, are fixedly connected to the front end of the splicing plate 12. First sliding grooves 10, evenly distributed, are provided through the front and rear ends of the splicing plate 12. An extension frame 4 is fixedly connected to the inner wall of the front end of the left opening 5 of the junction box body 1. Through holes 9 are provided through the front and rear ends of the extension frame 4. Three sets of equidistant first positioning posts 6 are fixed to the inner wall of the rear end of the right opening 5 of the junction box body 1. The upper and lower ends of the opening 5 are provided with slots 7. The inner wall of the slots 7 is fixed with positioning buckles 8 symmetrically distributed front and back. The upper and lower ends of the connecting baffle 3 are fixed with buckles 18. The front and rear ends of the connecting baffle 3 are provided with three sets of equidistant second sliding grooves 17. The buckles 18 are provided with positioning grooves 19 symmetrically distributed front and back. The cover plate 2 is set at the front end of the junction box body 1. The connecting baffle 3 is divided into two sets of left and right symmetrical sets. The connecting baffle 3 is set in the openings 5 ​​at the left and right ends of the junction box body 1.

[0024] The first positioning posts 6, splicing plates 12, and first sliding grooves 10 on the left and right sides of the junction box body 1 allow for the splicing and installation of multiple sets of junction box bodies 1. Two sets of connecting baffles 3 can be used to further splice and fix the multiple sets of junction box bodies 1 after splicing, ensuring flexibility and connection strength for splicing multiple sets of junction box bodies 1. The buckles 18 and positioning grooves 19 on the connecting baffles 3, in conjunction with the buckles 7 and positioning buckles 8 on the junction box body 1, enhance the flexibility and sturdiness of assembling the connecting baffles 3 and the junction box body 1 when used individually. This combination allows the junction box body 1 to be used individually or in multiple sets to meet different wiring installation needs.

[0025] Please see Figures 3-4 In this embodiment, left and right connecting posts 13 are fixedly connected to the inner wall of the rear end of the junction box body 1, and front and rear connecting posts 14 are fixedly connected to the upper and lower edges of the junction box body 1, which are symmetrically distributed. In use, the front and rear connecting posts 14 and the front and rear connecting cylinders 15 can facilitate the positioning and splicing of the cover plate 2 and the junction box body 1. Left and right connecting cylinders 16 are fixedly connected to the inner walls of the left and right ends of the cover plate 2, and front and rear connecting cylinders 15 are fixedly connected to the upper and lower ends of the cover plate 2, which can facilitate the positioning and splicing of the cover plate 2 and the junction box body 1.

[0026] Please see Figures 3-5 In this embodiment, the slot 7 is adapted to the buckle 18, and the positioning buckle 8 is adapted to the positioning groove 19. In use, the adapted slot 7 and buckle 18, the positioning buckle 8 and the positioning groove 19 can effectively improve the stability and firmness of the connecting baffle 3 installed in the openings 5 ​​on the left and right sides of the junction box body 1. The second slide groove 17 is adapted to the first positioning post 6 and the second positioning post 11, and the first slide groove 10 is adapted to the first positioning post 6. In use, the adapted second slide groove 17 and first positioning post 6, the second positioning post 11 and the first slide groove 10 and the first positioning post 6 can quickly assemble the splicing plate 12 and the opening 5 at the right end of the junction box body 1, and limit and fix the splicing plate 12 with the first positioning post 6, thereby ensuring the stability of splicing multiple sets of junction box bodies 1.

[0027] Please see Figures 4-5 In this embodiment, the connecting baffle 3 passes through the through hole 9, and the upper and lower ends of the connecting baffle 3 are fitted with the upper and lower ends of the opening 5. When in use, the connecting baffle 3 can limit and close the left and right ends of the junction box body 1 when used alone, or limit and close the opening 5 when multiple junction box bodies 1 are connected and assembled. The left and right connecting columns 13 and the left and right connecting cylinders 16 are connected by bolts, and the front and rear connecting columns 14 and the front and rear connecting cylinders 15 are connected by bolts. The rear end of the cover plate 2 is fitted with the front end of the junction box body 1. When in use, the bolt-installed cover plate 2 can facilitate the user to quickly assemble the junction box body 1 and the cover plate 2.

[0028] When a single junction box body 1 is used, first install the two sets of connecting baffles 3 into the openings 5 ​​on the left and right sides of the junction box body 1 respectively, and press the connecting baffles 3 to deform the buckles 18 and positioning grooves 19 into the slots 7 and positioning buckles 8 to complete the assembly of the connecting baffles 3 and the junction box body 1, and close the openings 5 ​​on the left and right sides of the junction box body 1. Then, the first positioning post 6 and the second positioning post 11 are used to position and fix the connecting baffles 3. The extension frame 4 and the through hole 9 thereon can provide additional limiting assistance for the connecting baffles 3 installed in the opening 5 on the left side of the junction box body 1 to improve the stability of the junction box body 1 when used alone.

[0029] Next, install the junction box body 1 into the wiring groove in the wall, and let the wire pass through the rear end of the junction box body 1 and set it inside the junction box body 1. Then, install the cover plate 2 into the junction box body 1 with bolts to complete the installation of the junction box body 1.

[0030] When multiple junction box bodies 1 are used, the splicing plate 12 on one set of junction box bodies 1 is first fitted onto the first positioning post 6, and so on, to initially assemble several sets of junction box bodies 1 that need to be installed.

[0031] Next, the left connecting baffle 3 is passed through the through hole 9 in the extension frame 4 and installed on the second positioning post 11, thereby performing a secondary splicing and fixing of the interconnected junction box bodies 1. Then, the right connecting baffle 3 is installed on the first positioning post 6, and the connecting baffle 3 is pressed as described above, so that the buckle 18 and the positioning groove 19 deform and are installed in the buckle groove 7 and the positioning buckle 8, so as to position, assemble and splice multiple sets of junction box bodies 1, thereby making it suitable for the installation and use of multiple wiring slots.

[0032] Through the above steps, the first positioning posts 6, splicing plates 12, and first sliding grooves on the left and right sides of the junction box body 1, together with two sets of connecting baffles 3, can perform multiple splicing and fixing of the multiple sets of junction box bodies 1 after left and right splicing. The buckles 18 and positioning grooves 19 on the connecting baffles 3, together with the buckles 7 and positioning buckles 8 on the junction box body 1, can improve the flexibility and sturdiness of assembling the connecting baffles 3 and the junction box body 1 when used alone. The two work together to allow the junction box body 1 to be used alone or in multiple sets to meet the needs of different wiring installations. This solves the problem that it is difficult to quickly splice a single junction box into multiple rows of junction boxes according to different wiring needs when using the existing 86-type junction box.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
