Description
Technical Field
[0001] The utility model relates to the technical field of air conditioner locks, in particular to a safety lock for an air conditioner. Background Art
[0002] The cover plates of existing air conditioners commonly use a two-stage locking mode: a compression type or a mortise lock plus a safety lock structure. The two-stage locking mode is mainly used to prevent the cover plate from flying open during violent bumps due to various human factors, such as directly covering the cover plate and forgetting to lock the lock with a key. Therefore, a safe, reliable and convenient safety locking device is needed. This device must be able to automatically lock when the cover plate is naturally lowered, and the cover plate can only be opened by manual unlocking. However, some of the existing safety locks have unreasonable structures and do not meet the requirements of safety locks. Some have overly complex structures, are prone to failure, have high processing costs, and poor versatility.
[0003] Such as Figure 1 shown, the structure of a safety lock is unreasonable, the lock tongue is too soft and prone to deformation. After being used for a period of time, it is difficult to lock, with poor reliability and potential safety hazards.
[0004] Such as Figure 2 shown, the structure of a safety lock is too complex, inconvenient for installation and maintenance. When unlocking, due to the limited opening angle of the cover plate, it is difficult to unlock; it requires a large installation space, high processing costs, and is not conducive to popularization to most products.

[0036] Please refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, a safety lock for an air conditioner in an embodiment is illustrated, which includes a fixing ring 1 welded in the housing of the air conditioner; a safety hook 2 connected to the cover plate of the air conditioner through a base; wherein the hook head 22 of the safety hook 2 is provided with an inclined surface 23 that contacts and locks with the fixing ring 1 during the locking process, and the hook body 21 of the safety hook 2 is provided with a limiting protrusion 24 that satisfies the firm positioning of the safety hook 2 in the fixing ring 1 after locking, and an unlocking flange 25 that must manually separate the hook head 22 from the fixing ring 1 during the unlocking process.
[0037] In this embodiment, as Figure 4 and Figure 5 shown, the safety hook 2 is installed with the base 4 through bolts 7, springs 3, flat gaskets 6 and self-locking nuts 5, and the spring 3 is located between the safety hook 2 and the flat gasket 6.
[0038] In this embodiment, as Figure 8 shown, the base 4 is provided with a limiting groove 42 for limiting one leg of the spring 3 after locking, and one side of the base 4 is bent 41 to form the limiting groove 42.
[0039] In this embodiment, as Figure 7 shown, the hook body 21 of the safety hook 2 is provided with a limiting flange 26 for limiting the other leg of the spring 3 during the unlocking process.
[0040] In this embodiment, the inclination angle range of the inclined surface 23 is 20° to 50°.
[0041] In this embodiment, the safety hook 2 is provided with a round hole 27 for installation with the base 4.
[0042] In this embodiment, as Figure 9 shown, the fixing ring 1 includes a fixing seat 11 and a U-shaped ring 12 connected to the fixing seat 11.
[0043] In this embodiment, the base 4 is provided with an installation hole 43 for installation with the cover plate of the air conditioner.
[0044] The characteristics and functions of the present utility model are further understood through the following description.
[0045] The safety lock of this embodiment mainly consists of the following parts: safety hook 2, fixed ring 1, spring 3, base 4 and fixing bolt assembly. The main technical features are as follows:
[0046] The outer shape structure of the safety hook 2 is simple and ingeniously conceived. The outer shape and structure design of the safety hook 2 are simple and ingeniously conceived, concentrating all the main functions required by the safety lock on this one safety hook 2. The safety hook 2 is processed from a stainless steel plate with a thickness of 2 mm or more. A slope 23 with an angle of 20 - 50 degrees is designed below the safety hook 2. When designing, the angle and length of this slope 23 need to fully consider the displacement caused by the deformation of the cover plate. The protruding part (i.e., the limit protrusion 24) in the upper left of the safety hook 2 is considered to contact the cover plate first when the safety hook is reset, playing a limiting role; the vertical flange (i.e., the limit flange 26) in the upper right is used to limit the spring 3 and at the same time strengthen the hook body 21; the horizontal flange (i.e., the unlocking flange 25) in the upper right is designed as the place where the human hand presses when unlocking; a circular hole 27 with a diameter of 7 is opened in the middle part above the safety hook 2 for installation. When designing, the height of the entire safety hook 2 also needs to be adjusted according to the actual situation of the product, fully considering the opening angle of the door cover plate to ensure that the unlocking part can be reached by a normal hand.
[0047] The fixed ring 1 is bent into a U-shaped ring 12 with a stainless steel wire with a diameter of 7 mm and is connected to the fixed seat 11, and the fixed seat 11 is directly welded to the unit housing.
[0048] The base 4 is processed from a stainless steel plate with a thickness of 2 mm or more.
[0049] Installation instructions: Weld the fixed ring 1 (or rivet it with a base added) at the corresponding position on the unit housing, weld the base 4 of the safety hook on the cover plate. In order to position and prevent water leakage at the same time, it can be welded after positioning by the boss positioning method; use a stainless steel bolt 7 of M6*30 to pass through the base 4, safety hook 2, spring 3, flat washer 6 in sequence, and finally put on the self-locking nut 5. First, screw the self-locking nut 5 on by hand for a few threads, adjust the spring 3, and place both ends of the spring 3 at the predetermined position for limiting. Tighten the self-locking nut 5, and pay attention to making the safety hook 2 rotate freely.
[0050] Working principle: As Figure 6 and Figure 7 shown, when the cover plate naturally falls and covers due to the action of gravity, the slope 23 of the safety hook 2 first contacts the fixed ring 1. Due to the action of the gravity of the cover plate, the safety hook 2 rotates a certain angle around the bolt 7 and then the cover plate falls and covers, while the safety hook 2 returns to its original position under the action of the spring 3 force.
[0051] When the cover plate needs to be opened, after pulling the cover plate upward at a certain angle, according to the operation prompts on the cover plate, gently pinch the unlocking flange 25 on the safety hook 2 with your hand, as Figure 6 shown by the arrow in the figure, the safety hook 2 rotates around the bolt 7 at a certain angle to unlock, and the cover plate can be opened.
[0052] To sum up, the safety lock for the air conditioner of the present utility model has a simple structure and ingenious design. The positioning of the spring and the unlocking handle are all integrated on the small safety hook made of sheet metal, overcoming the deficiencies of existing products, fully considering the deformation of the cover plate, being convenient for installation and maintenance, and having stable and reliable performance. It is an innovative technical improvement.
[0053] The above are only the preferred embodiments of the present utility model, and do not limit the implementation manners and protection scope of the present utility model accordingly. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the description and illustrations of the present utility model should be included in the protection scope of the present utility model.
