Description

Technical Field

[0001] This utility model belongs to the field of instrument housing technology, specifically relating to a waterproof integrated instrument housing. Background Technology

[0002] Waterproof integrated instrument housing is a special housing designed to protect the internal electronic components of various instruments. It can effectively prevent liquid intrusion and ensure that the instrument works stably in complex environments such as humidity, immersion, and dust.

[0003] Existing integrated instrument housings involve snapping the housing onto the instrument body during installation, then fitting a sleeve over the housing and bolting it to the instrument body to lock the housing in place. However, because the housing, instrument body, and sleeve are all in a close fit, gaps exist. Furthermore, despite the integrated design, insufficient mold precision during injection molding or die casting can create micro-gaps between the housing and the housing, invisible to the naked eye. Over time, vibrations or impacts during use can widen these gaps, creating water seepage channels and compromising waterproofing. Therefore, this invention proposes a waterproof integrated instrument housing. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof integrated instrument housing to solve the problem mentioned in the background art that the integrated instrument housing is in a fitted state with the instrument body and the protective sleeve, resulting in insufficient sealing, and that if the precision of the integrated instrument housing is insufficient during processing, the gap between the integrated instrument housing and the instrument body and the protective sleeve will increase.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof integrated instrument housing, comprising an integrated body housing disposed on the instrument body, and a protective sleeve sleeved on the integrated body housing and located on the instrument body. The integrated body housing consists of an upper shell and a lower base. The lower base is fixed to the bottom of the upper shell. A waterproof sealing mechanism is provided at the contact point between the lower base and the waterproof sealing mechanism. The waterproof sealing mechanism consists of a lip structure and a sealing component. The lip structure is fixed to the surface of the lower base. The sealing component consists of a main sealing component, an auxiliary sealing groove, and an auxiliary sealing block. The auxiliary sealing groove is opened on the surface of the instrument body. The main sealing component is disposed at the bottom of the lower base. The auxiliary sealing block is disposed inside the main sealing component and located at the bottom of the lower base.

[0006] Preferably, the main sealing assembly consists of a rubber base and a rubber sealing gasket, the rubber sealing gasket being disposed at the bottom end of the lower base, and the rubber base being fixed between the rubber sealing gasket and the lower base.

[0007] Preferably, the auxiliary sealing block consists of a locking block, a rubber pad, and a mounting groove. The locking block is fixed to the bottom end of the lower base, the mounting groove is opened at the bottom end of the locking block, and the rubber pad is fixed to the inner side of the mounting groove.

[0008] Preferably, the surface of the card block, the surface of the rubber pad, and the inner wall of the auxiliary sealing groove are in contact.

[0009] Preferably, the lower base has a trapezoidal cross-section.

[0010] Preferably, the sheath and the instrument body are provided with multiple mounting holes at the contact points, and bolts pass through the inner side of the mounting holes.

[0011] Preferably, the end cross-section of the auxiliary sealing block has a rectangular structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By designing a waterproof sealing mechanism, the original unibody casing's protection of the instrument was improved. Because the unibody casing was fitted to the instrument body and sheath using bolts, gaps remained at the joint. Furthermore, insufficient precision during manufacturing allowed vibrations or impacts during long-term use, widening these gaps and compromising waterproofing. The new waterproof sealing mechanism addresses this by using a lip structure at the joint between the sheath and the lower base. During installation, the lip structure is compressed and deformed to fit tightly against the casing surface. The lower base and instrument body are sealed with a double seal: the main seal is a high-elasticity rubber gasket with a snap-fit ​​structure. Even if the main seal fails, the auxiliary seal groove can still block moisture, increasing the unibody casing's waterproofing and ensuring its effectiveness in protecting the instrument after installation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5This utility model provides a technical solution: a waterproof integrated instrument housing, including an integrated body housing 2 disposed on an instrument body 1, and a protective sleeve 4 sleeved on the integrated body housing 2 and located on the instrument body 1. The integrated body housing 2 is composed of an upper housing 21 and a lower base 22. The lower base 22 is fixed to the bottom of the upper housing 21. A waterproof sealing mechanism 3 is provided at the contact point between the lower base 22 and the waterproof sealing mechanism 3. The waterproof sealing mechanism 3 is composed of a lip structure 31 and a sealing component 32. The lip structure 31 is fixed to the surface of the lower base 22. The sealing component 32 is composed of a main sealing component 321, an auxiliary sealing groove 322, and an auxiliary sealing block 323. The auxiliary sealing groove 322 is formed in the instrument body. On the surface of 1, the main sealing component 321 is located at the bottom of the lower base 22, and the auxiliary sealing block 323 is located inside the main sealing component 321 and at the bottom of the lower base 22. Through the designed waterproof sealing mechanism 3, the original integrated body shell 2 is improved. In the process of protecting the instrument, because the integrated body shell 2 is in a close fit with the instrument body 1 and the protective sleeve 4 and is locked by bolts, there is still a gap at the fit between the integrated body shell 2 and the instrument body 1 and the protective sleeve 4. Moreover, when the precision of the integrated body shell 2 is insufficient during production, vibration or impact occurs during long-term use after installation, which increases the gap at the fit between the integrated body shell 2 and the instrument body 1 and the protective sleeve 4. The original design lacked sufficient waterproofing. To address this, a waterproof sealing mechanism 3 was installed at the interface between the integrated casing 2, the instrument body 1, and the protective sleeve 4. This mechanism seals the interface between the protective sleeve 4 and the lower base 22 via a lip structure 31. During installation, the lip structure 31 is compressed and deformed, tightly adhering to the casing surface. The interface between the lower base 22 and the instrument body 1 is double-sealed via a sealing component 32. The main sealing component 321 is a high-elasticity rubber gasket, and the sealing component 32 has a snap-fit ​​structure. Even if the main sealing component 321 fails, the auxiliary sealing groove 322 can still block moisture, increasing the waterproofing of the integrated casing 2 and ensuring the waterproof effect of the integrated casing 2 on the instrument after installation. The auxiliary sealing block 323 consists of a snap-fit ​​block 3231... The device consists of a rubber pad 3232 and a mounting groove 3233. A locking block 3231 is fixed to the bottom end of the lower base 22. The mounting groove 3233 is opened at the bottom end of the locking block 3231. The rubber pad 3232 is fixed to the inner side of the mounting groove 3233. The auxiliary sealing groove 322 and the auxiliary sealing block 323 are connected by a locking method through the auxiliary sealing block 323, which has a certain waterproof effect. The surface of the locking block 3231, the surface of the rubber pad 3232 and the inner wall of the auxiliary sealing groove 322 are in a close fit. The cross-section of the lower base 22 is trapezoidal. Multiple mounting holes are provided at the contact points between the sheath 4 and the instrument body 1, and bolts pass through the inner side of the mounting holes. The end cross-section of the auxiliary sealing block 323 is rectangular.

[0022] In this embodiment, preferably, the main sealing assembly 321 consists of a rubber base 3211 and a rubber sealing gasket 3212. The rubber sealing gasket 3212 is disposed at the bottom end of the lower base 22, and the rubber base 3211 is fixed between the rubber sealing gasket 3212 and the lower base 22. The main sealing assembly 321 is the main sealing structure and plays the main waterproofing role.

[0023] The working principle and usage process of this utility model are as follows: During the installation of the integrated body shell 2, the integrated body shell 2 is first engaged with the instrument on the instrument body 1, and the auxiliary sealing block 323 at the bottom of the lower base 22 is engaged with the inner side of the auxiliary sealing groove 322. The main sealing component 321 is attached to the surface of the instrument body 1 to seal the instrument. Then, the protective sleeve 4 is put on the integrated body shell 2 and bolted between the protective sleeve 4 and the instrument body 1 to lock the contact between the integrated body shell 2, the instrument body 1, and the protective sleeve 4. The lip structure 31 and the main sealing component 321 are squeezed to complete the installation of the integrated body shell 2. The lip structure 31 and the sealing component 32 make the integrated body shell 2 waterproof after installation.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
