Abstract
Description
Technical Field
[0001] The utility model relates to a hinge for a shower room, in particular to a hinge joint. Background Art
[0002] In the prior art, the hinge joint for a shower room usually consists of two hinge joint bodies. Corresponding through holes penetrating the upper and lower ends are provided on the two hinge joint bodies. A rotating shaft is installed in the through holes to rotatably connect the two hinge joint bodies. Both ends of the rotating shaft will be exposed above and below the hinge joint, affecting the aesthetics. In addition, in places with heavy water vapor such as shower rooms, water vapor easily slowly seeps in from the gap between both ends of the rotating shaft and the through hole. Especially for the convenience of installation, chamfers are generally provided at both ends of the rotating shaft, and grooves are formed between both ends of the rotating shaft and the diameter of the hinge joint, making it easier to store water (especially in the lower hinge joint, where water is more likely to splash in), thus increasing the leakage speed and causing internal rust, which not only affects the aesthetics of the hinge joint but also its service life. Content of the Utility Model
[0003] In order to overcome the deficiencies of the prior art, the utility model provides an internal and external hinge joint with a hidden rotating shaft.
[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0005] An internal and external hinge joint with a hidden rotating shaft, including a stationary page and a movable page. The movable page includes a hinge joint seat. One end of the hinge joint seat close to the stationary page is provided with a concave cavity. An installation hole penetrating the upper and lower ends is provided in the concave cavity. A rotating shaft is fixedly installed in the installation hole. The stationary page is provided with a connecting sleeve, and the connecting sleeve is sleeved outside the rotating shaft. A first waterproof rubber pad is installed inside the hinge joint seat. The first waterproof rubber pad is provided with a waterproof baffle. After assembly, the waterproof baffle closes the installation hole. A front cover is slidably installed on the front side of the hinge joint seat. In the natural state, the front cover covers the front side of the connecting sleeve.
[0006] The hinge joint seat and the front cover are connected by a tension spring. One end of the tension spring is close to the stationary page and fixed on the hinge joint seat, and the other end is far from the stationary page and fixed on the front cover.
[0007] A front cover rubber pad is installed between the hinge joint seat and the first waterproof rubber pad. The front cover rubber pad is provided with a plug-in part. A plug-in groove is provided on the inner side of the front cover. After assembly, the plug-in part is inserted into the plug-in groove, and the front cover rubber pad closes the tension spring.
[0008] A sliding rubber pad is installed on the front side of the connecting sleeve. An arc-shaped portion is provided on the end face of the front cover close to the stationary page. When the movable page rotates outward, after the surface of the arc-shaped portion contacts the surface of the sliding rubber pad, the tension spring undergoes elastic deformation, causing the front cover to slide outward relative to the hinge seat. When the outward rotation of the movable page stops, the tension spring elastically restores and causes the front cover to slide toward the stationary page.
[0009] An anti-collision gasket is installed at one end of the hinge seat away from the stationary page. After assembly, the anti-collision gasket is located between the hinge seat and the front cover.
[0010] Two symmetrical bushings are installed on the rotating shaft. A limiting edge extends outward from the outer end edge of the bushing, and the limiting edge abuts against the end face of the connecting sleeve.
[0011] Inner grooves are provided at the upper and lower ends of the connecting sleeve, and the limiting edge abuts against the bottom surface of the inner groove.
[0012] Clamping components for clamping the glass door are installed on both the stationary page and the movable page.
[0013] The beneficial effects of the present utility model are as follows: A concave cavity is provided at one end of the hinge seat close to the stationary page. An installation hole penetrating through the upper and lower ends is provided in the concave cavity. A rotating shaft is fixedly installed in the installation hole. The stationary page is provided with a connecting sleeve, and the connecting sleeve is sleeved on the outer side of the rotating shaft. A first waterproof rubber pad is installed on the inner side of the hinge seat. The first waterproof rubber pad is provided with a waterproof baffle. After assembly, the waterproof baffle closes the installation hole, effectively preventing water from seeping into the rotating shaft, preventing internal rust, and improving the service life.
[0014] In addition, a front cover is slidably installed on the front side of the hinge seat. The hinge seat and the front cover are connected by a tension spring. Due to the elasticity of the tension spring, after the front cover slides outward relative to the hinge seat, the tension spring elastically restores, and the front cover can be returned to its original position, which is convenient to use. In the natural state, the front cover covers the front side of the connecting sleeve, covering the notches at both ends of the connecting sleeve. On the one hand, it prevents water from seeping in, and on the other hand, it improves the external aesthetics. BRIEF DESCRIPTION OF THE DRAWINGS
