Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning controller interfaces, in particular to a central air-conditioning controller interface. Background Art

[0002] The central air conditioning controller is a key component of the central air conditioning system, also known as the central air conditioning thermostat. It can control parameters such as indoor temperature, humidity, fresh air volume, exhaust air volume, etc., thereby ensuring the comfort and air quality of the indoor environment. In order to meet the power connection needs of the controller, the central air conditioning controller will be equipped with multiple interfaces for connection with the wires.

[0003] When the central air-conditioning controller is being wired, the staff directly inserts the wire into the interface, and then uses the locking screw to press the wire head onto the elastic terminal piece to make it contact with the terminal piece for conduction. However, since the inner diameter of the controller interface is relatively large, there is still a large gap between the wire and the interface when it is inserted. When the southerly weather comes, due to the high air humidity at this time, water vapor and dust in the air can easily enter the interface, which can easily cause the controller to be short-circuited. For this reason, we propose a central air-conditioning controller interface to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a central air-conditioning controller interface.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 , a central air conditioning controller interface, including a controller body 1, a wiring port 2 is provided inside the controller body 1, and the outer side of the wiring port 2 is covered with a protective plate 3, the connection method of the controller body 1 and the wiring port 2 is the existing technology, which will not be described in detail here, a connecting rod 4 is symmetrically connected to the inner side of the protective plate 3, a connecting groove 5 adapted to the connecting rod 4 is provided inside the controller body 1, and a limiting rod 6 is inserted into the inner wall of the controller body 1 above the connecting groove 5, one end of the limiting rod 6 extends to the upper side of the controller body 1, and the other end of the limiting rod 6 is inserted in the connecting rod 4, and a card slot adapted to the limiting rod 6 is provided inside the connecting rod 4, and two groups of card slots adapted to the limiting rod 6 are provided inside the connecting rod 4, so that the protective plate 3 can be limited when pushed out and covered, a wire 11 is clamped inside the wiring port 2, and a threading groove adapted to the wire 11 is provided inside the protective plate 3, and the wire 11 can be smoothly inserted from the threading groove into the wiring port 2 for wiring by opening the threading groove.

[0024] Further, see Figure 2 and Figure 4 It can be known that a linkage rod 7 is provided above the controller body 1, and the end of the linkage rod 7 is connected to the top of the two groups of limit rods 6. The linkage rod 7 is arranged as a U-shaped structure. The linkage rod 7 arranged through the U-shaped structure can facilitate the staff to pull the two groups of limit rods 6 and lift them up at the same time to quickly contact the limit of the connecting rod 4, thereby effectively improving the convenience of the device during use.

[0025] Further, see Figure 4 It can be known that a movable groove compatible with the limit rod 6 is opened inside the controller body 1, and a connecting ring 8 is inserted inside the movable groove. The connecting ring 8 is fixedly sleeved on the outside of the limit rod 6, and the outer wall of the connecting ring 8 abuts against the inner wall of the movable groove. By abutting the connecting ring 8 with the inner wall of the movable groove, the linkage rod 7 can be guided to meet the requirement of stable up and down movement of the linkage rod 7.

[0026] Further, see Figure 4 It can be known that the side of the connecting rod 4 away from the protective plate 3 is connected to the limiting plate 10, and the opening diameter of the connecting groove 5 is smaller than the diameter of the limiting plate 10. The connecting rod 4 can be limited by the limiting plate 10 with a larger diameter to effectively prevent the connecting rod 4 from being completely pulled out from the inside of the connecting groove 5.

[0027] Further, see Figure 5 It can be known that the inner walls of the wire threading groove are glued with rubber rings 12, and the opening position of the rubber ring 12 is set to an arc structure. The inner wall of the rubber ring 12 and the outer wall of the wire 11 fit tightly. The rubber ring 12 set by rubber material can further block water vapor, and because the opening of the rubber ring 12 is set to an arc shape, it is convenient for the staff to insert the wire 11 through the rubber ring 12.

[0028] Further, see Figure 5 It can be known that the outer wall of the protective plate 3 above the rubber ring 12 is connected to a threaded rod 13, and a rotating plate 14 is sleeved on the outer side of the threaded rod 13. The outer side of the threaded rod 13 is connected to the threaded sleeve 15 through a thread. When part of the wire threading groove is not inserted with the wire 11, the wire threading groove can be sealed by covering it with the rotating plate 14. When the wire 11 needs to be inserted, the staff only needs to rotate the rotating plate 14 so that it no longer covers the wire threading groove, and then rotate the threaded sleeve 15 to make it abut against the rotating plate 14 to limit the rotating plate 14.

[0029] Further, see Figure 4 It can be known that a spring 9 is vertically connected to the lower side of the connecting ring 8, and the other end of the spring 9 is connected to the inner wall of the movable groove. Through the elastic characteristics of the spring 9 itself, when the positions of the limit rod 6 and the slot opened inside the connecting rod 4 correspond to each other, the limit rod 6 can be automatically embedded in the slot of the connecting rod 4 through the elastic force of the spring 9, thereby improving the convenience during use.

[0030] Working principle: When the utility model is in use, when wiring is required, the staff can first pull up the linkage rod 7, so that it drives the two groups of limit rods 6 to be lifted up at the same time, so that the limit rod 6 is pulled out from the inside of the connecting rod 4, thereby releasing the limit on the connecting rod 4, and then the staff can pull the protective plate 3, so that it drives the connecting rod 4 to slide inside the connecting groove 5 at the same time. When the position of the other group of card grooves opened inside the connecting rod 4 corresponds to the position of the limit rod 6, the limit rod 6 can be embedded in the connecting rod 4 through the elastic force of the spring 9, thereby realizing the re-limitation of the connecting rod 4. At this time, the protective plate 3 can be separated from the wiring port 2, and each group of locking screws can be exposed;

[0031] Then the staff can rotate the threaded sleeve 15 so that it no longer contacts the rotating plate 14. At this time, the staff can rotate the rotating plate 14 to rotate along the center of the threaded rod 13 to expose the opening of the wire threading groove of the protective plate 3. Then the staff can rotate the threaded sleeve 15 in the opposite direction to fix the position of the rotating plate 14. At this time, the staff can insert the corresponding wire 11 into the wire threading groove inside the protective plate 3 and push it into the wiring port 2. Then, the locking bolt is tightened with a screwdriver or other tool to connect the wire 11 to the interface. After the wire 11 is connected, the staff can pull up the linkage rod 7 again, and then push the protective plate 3 to cover and protect the wiring port 2 again. Then the staff can embed and install the controller body 1 in a suitable position to control the central air conditioner. The above is the entire working principle of the utility model.

[0032] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0033] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
