Description

Technical Field

[0001] The utility model belongs to the technical field of industrial control switches, and in particular relates to a waterproof industrial control switch. Background Art

[0002] An industrial control switch is an electrical component used to control the switching state of a circuit. It has high durability and reliability and is generally used for automated control of automobiles, industrial equipment, electronic equipment, etc.

[0003] The shell of the existing industrial switch is composed of an upper shell and a lower shell, which are generally connected by a snap. There is a certain gap between the upper shell and the lower shell connected by the snap, and water vapor or dust can easily enter the inner part of the industrial switch shell through the gap, affecting the normal use of the industrial switch. To solve this problem, sealant is usually used to fill the gap to prevent water vapor or dust from entering the shell.

[0004] However, since the gap between the upper shell and the lower shell is in direct contact with the outside world, the sealant is also in direct contact with the outside world. After long-term use, the sealant is prone to aging, affecting the sealing connection effect between the upper shell and the lower shell. In addition, the sealant is directly exposed to the outside, which makes the shell less beautiful. Summary of the invention

[0005] In view of the existing industrial control switch, the sealant between the upper shell and the lower shell is in direct contact with the outside world, which is easy to age after long-term use, affecting the sealing connection effect between the upper shell and the lower shell. The following utility model is now proposed:

[0006] A waterproof industrial control switch comprises an upper shell and a lower shell. A sealant for fixing the upper shell and the lower shell is provided in a gap at the connection between the upper shell and the lower shell. A first annular sealing groove is provided on the upper shell, and a second annular sealing groove is provided on the lower shell. After the upper shell and the lower shell are connected, the first sealing groove and the second sealing groove are combined to form an annular total sealing groove. A first sealing strip and a second sealing strip are respectively provided on both sides of the total sealing groove. The first sealing strip and the second sealing strip completely cover the gap between the upper shell and the lower shell to prevent the sealant from directly contacting the outside world.

[0007] Furthermore, the first sealing strip and the second sealing strip are respectively provided with a first plug and a first slot at both ends, the first plug on the first sealing strip is inserted into the first slot on the second sealing strip, and the first plug on the second sealing strip is inserted into the first slot on the first sealing strip.

[0008] Furthermore, fixing sleeves are provided at both ends of the first sealing strip and the second sealing strip to fix the two, a second slot is provided at the bottom of the first plug block and the first slot, and a second plug block matching the second slot is provided in the fixing sleeve.

[0009] Furthermore, the first sealing strip and the second sealing strip are fixedly installed in the main sealing groove by means of sealant.

[0010] The utility model proposes a waterproof industrial control switch, which has the beneficial effect that a general sealing groove is provided at the connection between the upper shell and the lower shell, and a first sealing strip and a second sealing strip are provided in the general sealing groove, which can completely cover the gap between the upper shell and the lower shell to avoid direct contact of the sealant with the outside world, thereby effectively delaying the aging speed of the sealant and improving the waterproof and dustproof stability of the waterproof industrial control switch.

[0017] The technical solution of the utility model will be clearly and completely described below in conjunction with embodiments.

[0018] Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0019] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described here are described.

[0020] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0021] like Figure 1-Figure 3 As shown, it is an embodiment preferred by the utility model, a waterproof industrial control switch, comprising an upper shell 1 and a lower shell 2, the upper shell 1 is sleeved on the lower shell 2, and a sealant filling the gap and fixing the two is provided at the gap where the upper shell 1 and the lower shell 2 contact each other, a first annular sealing groove 11 is provided at the bottom of the upper shell 1, and a second annular sealing groove 12 is provided at the top of the lower shell 2. After the upper shell 1 is in contact and connected with the lower shell 2, the first sealing groove 11 and the second sealing groove 12 are combined to form an annular total sealing groove 13, and a first sealing strip 3 and a second sealing strip 4 are respectively provided on both sides of the total sealing groove 13 and are fitted therein, and the first sealing strip 3 and the second sealing strip 4 are in contact at both ends, and the sealant at the contact between the upper shell 1 and the lower shell 2 is blocked by the sealing strip to avoid direct contact between the sealant and the outside world. In this embodiment, the first sealing strip 3 and the second sealing strip 4 are fixedly installed in the total sealing groove 13 by the sealant.

[0022] Due to the shielding of the first sealing strip 3 and the second sealing strip 4, the sealant between the upper shell 1 and the lower shell 2 will not be directly exposed to the outside world, thereby reducing the possibility of aging and failure of the sealant, thereby effectively preventing water vapor and dust from entering the interior of the industrial control switch.

[0023] On this basis, a first plug block 31 and a first slot 32 are respectively provided at both ends of the first sealing strip 3 and the second sealing strip 4, wherein the first plug block 31 on the first sealing strip 3 is inserted into the first slot 32 on the second sealing strip 4, and the first plug block 31 on the second sealing strip 4 is inserted into the first slot 32 on the first sealing strip 3; Figure 4As shown, a fixing sleeve 5 for fixing the first plug block 31 and the first slot 32 is provided at both ends of the first sealing strip 3 and the second sealing strip 4. Specifically, a second slot 52 is provided at the bottom of the first plug block 31 and the first slot 32, and a second plug block 51 matching the second slot 52 is provided in the fixing sleeve 5.

[0024] The first inserting block 31 cooperates with the first inserting slot 32 to strengthen the fixed connection between the first sealing strip 3 and the second sealing strip 4 , and the fixing sleeve 5 further prevents the first inserting block 31 and the first inserting slot 32 from loosening.

[0025] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
