Description

Door opening and closing device of wall-mounted product

The present invention relates to a wall-mounted product used as communication equipment, and in particular, the gear portion formed integrally with the door and the pin spring inserted into the pin fixing part formed to extend from the main body to control the opening and closing of the door-type product. It relates to a door opening and closing device.

Typically, a wall-mounted product used as communication equipment is attached to the outside of the building, the inside of the wall-mounted product is provided with an operation unit such as a rotary switch to adjust the operation mode. Therefore, a door is formed in the wall-mounted product cover to protect the interior including the operation unit from the outside.

In the related art, as illustrated in FIGS. 1A and 1B, in a wall-mounted product used as communication equipment, hinge portions 12 are formed on one side of the door 2 above and below. The hinge portion 12 extends from one side of the door and includes a shaft hole 5 into which the hinge shaft 3 can be inserted. The hinge shaft 3 has a circular cross section, and a hook groove 4 is formed at one end thereof so that the hinge shaft 3 is coupled to the bracket 6 so that the hinge shaft 3 is not inserted after being inserted into the shaft hole 5. do. The bracket 6 is attached to the lower end of the hinge portion 12 and the main body 1 to fix the hinge shaft 3 inserted through the hinge hole and the shaft hole of the main body. The bracket 6 protrudes around the hole formed so that the screw is inserted, and a boss 7 is formed to prevent abrasion of the hole. A fixing screw 9 is inserted through the boss to insert the bracket 6 and the main body. Combine (1). In addition, the lower portion of the bracket 6 is provided with a fixing plate 8 for fixing the position of the bracket. On the other hand, the locking projection 10 is formed on the other side of the upper and lower sides of the door 2, and when the door is closed, the locking projection is caught by the locking groove 11 formed in the main body of the door and is fixed.

However, the door opening and closing device of the wall-mounted product configured as described above consumes a large number of parts such as fixing screws, brackets, and fixing plates at the rotating part for opening and closing the door, which causes a decrease in productivity and a cost increase, and fixes the closed state of the door. In order to prevent the protrusion formed on the door, the door is gradually worn out as the service period of the door has elapsed, and thus, the locking protrusion may not play its original role as the locking protrusion.

In order to solve the above problems, an object of the present invention is to provide a door opening and closing device of a wall-mounted product that reduces the number of components, and performs the opening and closing function without the use of fasteners such as screws.

Another object of the present invention is to provide a door opening and closing device of a wall-mounted product to prevent performance degradation due to abrasion even after long time use.

In order to achieve the above object, the present invention provides a door opening and closing device for a wall-mounted product, wherein the door opening and closing device is inserted into a fixing groove and a fixing jaw extending from the main body, and a pin fixing part extending from the main body. When the pin spring is inserted, the gear portion integrally formed with the door during opening and closing of the door is in contact with the pin spring to control the opening and closing of the door.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used for the same components, even if displayed on different drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Wall-mounted products in the general case is attached to the outside of the building, the inside of the wall-mounted product is provided with a control unit such as a rotary switch to adjust the operation mode. In such a wall-mounted product, a door is formed in the wall-mounted product cover to protect the interior including the operation unit from the outside.

As shown in FIG. 2, the door 2 of the wall-mounted product is formed with a gear 32 extending from the door. One end of the gear 32 is integrated with the door, and one end is coupled to the rotation shaft 30 in a triangular shape. The outer side surface of the toothed portion 32 is continuous in the thread-shaped bend, wherein the bend closest to the door is formed deeper than other bends. Also. The gear 32 is formed on both upper and lower sides of the door, and the outer side of the gear is formed with a rotating plate 31 extending from the door to reinforce the gear from external force and share the load of the door with the gear. .

On the other hand, the main body coupled with the gear portion is formed with a fixing groove 51 and a fixing jaw 52 protruding from the outer body 50, as shown in Figure 2, the pin fixing part protruding from the inner body 54 55 is formed. In addition, as shown in FIG. 6, the guide 53 extending from the outer body 50 is formed to surround the rotation shaft 30 on the outside of the fixing groove 51 so that the rotation shaft 30 is not separated. do. In addition, a guide rib 57 extending from the main body is formed inside the pin fixing part 55, and the pin spring 56 is inserted between the pin fixing part 55 and the guide rib 57, and then the pin spring. A pin fixing plate 58 extending from the main body is formed on the outer side of the pin fixing part 55 so that the pin spring 56 is between the pin fixing part 55 and the guide rib 57. After insertion, fix the upper and lower positions of the pin spring.

Referring to the operation of the door opening and closing device of the wall-mounted product having the configuration as described above are as follows.

In the closed state of the door, as shown in FIG. 3, the pin spring 56 inserted between the pin fixing part and the guide rib is caught and fixed to the bend closest to the door side among the bends formed in the gear 32. When the door is opened, as shown in FIG. 4, the door 2 is opened while the pin spring 55 contacts the bend formed in the gear 32 according to the rotation angle of the rotation shaft 30, and when the door is completely opened, the door 2 is opened. The pin spring 55 catches the last bend of the gear 32 to keep the door open. In such a door opening and closing device, opening and closing of the door is made by contact between the pin spring 55 and the bent portion of the gear 32, thereby maintaining the angle by opening the door 2 to a desired degree. The door is completely open as shown in FIG. 5.

As described above, the door opening and closing device of the wall-mounted product according to the embodiment of the present invention significantly reduces the number of components, thereby improving productivity and reducing costs, and the user can arbitrarily adjust the opening angle of the door. .
