Detailed ways

The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the specification of the present invention.

For reasons of convenience only, in the following description, specific directional terms, such as "up", "down", "left", "right", etc., are used with reference to the corresponding drawings and It should not be regarded as a limitation on the present invention, and when the defined direction of the drawings changes, the directions indicated by these words should be interpreted as correspondingly different directions.

As shown in FIG. 1 , a chain hinge for a shower room provided by the present invention includes a first hinge bracket 11 , a second hinge bracket 12 , a first rotating shaft 31 , a second rotating shaft 32 and two connecting pieces 2 .

Wherein, the first hinge bracket 11 and the second hinge bracket 12 are identical parts that can be replaced with each other, and the inner surfaces of their fixed ends are respectively provided with fixing parts 110 for fixed connection with the shower room wall. The connecting ends of the first hinge bracket 11 and the second hinge bracket 12 are respectively hinged to the two ends of the two connectors 2 through the first rotating shaft 31 and the second rotating shaft 32, wherein the first rotating shaft 31 and the second rotating shaft 32 can also be connected to each other. Replaced identical parts.

Specifically, the connecting end of the first hinge bracket 11 has three lugs 111 protruding from top to bottom in parallel to the left, and each of the three lugs 111 has a through hole, and every two adjacent lugs A square groove is formed between 111. In the embodiment of the present invention, there are two connecting pieces 2 , and two ends of each connecting piece 2 respectively have a through hole in the vertical direction. When installing, place one end of the two connectors 2 respectively in the two square grooves of the first hinge bracket 11, and set the through holes on the connectors 2 opposite to the through holes on the ear socket 111, using the first The rotating shaft 31 passes through the through hole on the ear seat 111 and the connecting parts 2 to hinge the first hinge bracket 11 and the two connecting parts 2 .

As an improvement, a decorative cover 113 is detachably installed on the first hinge bracket 11, and the decorative cover 113 covers the outer side of the through hole of the ear seat 111 at the edge of the connecting end of the first hinge bracket 11, that is, covers the uppermost ear. The upper side of the through hole of the seat 111 and the lower side of the through hole of the lowermost ear seat 111 axially fix the first rotating shaft 31 in the space formed by the ear seat 111 and the through hole of the connector 2 . In addition, the decorative cover 113 also covers the outer surface of the fixed end of the first hinge bracket 11 for decoration and beautification. By replacing the decorative cover 113 with different colors and patterns, the chain hinge of the embodiment of the present invention can have different appearances to match different decoration styles of shower rooms.

The specific structure of the second hinge bracket 12 is consistent with that of the first hinge bracket 11 , similarly, the second hinge bracket 12 is hinged to the left ends of the two connecting parts 2 through the second rotating shaft 32 .

Special attention should be paid to the side of one end of the connecting piece 2 described in the embodiment of the present invention hinged with the first hinge bracket 11, that is, the right side of the connecting piece 2 shown in FIG. 1 is provided with two axial protrusions. The two protruding ribs are respectively clamped at the openings on both sides of the square groove of the first hinge bracket 11, and are used to fix the first hinge bracket 11 in the direction of rotation and prevent it from rotating on the connector 2. At the same time, in order to further fix the first hinge bracket 11 and the connecting piece 2 in the direction of rotation, the right side of the connecting piece 2 is also provided with a blind hole, and the square groove of the first hinge bracket 11 is also provided correspondingly. There is a through hole, the through hole in the square groove of the first hinge bracket 11 is set opposite to the blind hole of the connecting piece 2, and is fixedly connected by the positioning joint 112 .

Same as the first hinge bracket 11 , the second hinge bracket 12 also has a through hole in the square groove, and the through hole is used to fix the nylon pad 122 . The nylon pad 122 is used for lubricating, damping and noise reduction between the second hinge bracket 12 and the connecting piece 2, preventing the second hinge bracket 12 from directly contacting or colliding with the connecting piece 2 during the rotation process, resulting in zero Wear and tear of components. Correspondingly, as an improvement, nylon pads 20 are also provided on the sides of the through holes at both ends of the connector 2 .

The side of one end of the connecting piece 2 hinged with the second hinge bracket 12, that is, the left side of the connecting piece 2 shown in FIG. 2, the minimum included angle between the inner surfaces of the first hinge bracket 11 and the second hinge bracket 12 is limited to 90° to 180°. That is, when the two shower room walls are fixedly connected to the first hinge bracket 11 and the second hinge bracket 12 respectively, the angle of the inner corner between the two shower room walls is limited to 90° to 180° by the connector 2, and the replacement is different. Different shapes of the connecting piece 2 can realize different functions of limiting the minimum included angle.

Specifically, in the embodiment of the present invention, the rib on the left side of the connecting member 2 limits the minimum angle between the inner sides of the first hinge bracket 11 and the second hinge bracket 12 to 135°.

In the other two embodiments of the present invention, there are also provided connector structures with two other angle limiting ranges.

As shown in Figure 2, the left end of the connecting piece 2 in the second embodiment of the present invention is fixedly connected with the first hinge bracket 11, and the rib on the right side of the connecting piece 2 is used to limit the rotation angle of the second hinge bracket 12, The minimum included angle between the inner surfaces of the first hinge bracket 11 and the second hinge bracket 12 is limited to 180°.

As shown in Figure 3, the left end of the connecting piece 2 in the third embodiment of the present invention is fixedly connected with the first hinge bracket 11, and the rib on the right side of the connecting piece 2 is used to limit the rotation angle of the second hinge bracket 12, The minimum included angle between the inner surfaces of the first hinge bracket 11 and the second hinge bracket 12 is limited to 90°.

Multiple embodiments of the present invention provide chain hinges for shower rooms, in which the hinge brackets, rotating shafts and decorative covers are all common, and when assembling the shower room, only the connecting piece with the function of defining the corresponding corner range is selected, It can be assembled into a chain hinge with a minimum rotation angle of 180°, 135° or 90°, including all forms of hinges with three different angles generally required by shower rooms, and can be flexibly adapted to all installation requirements. At the same time, the chain hinge in the form of "3+2" connection is more stable and reliable than the hinge structure in the form of traditional "2+1" connection.

All the parts of the chain hinge used in the shower room provided by the present invention are detachable and installed, and most of the parts are universal, and different installation requirements can be met by simply replacing the connecting parts; it not only ensures the product style It is complete and reduces the types of hinge products required in the shower room assembly process, greatly reducing the cost of mold development and parts management.

The above-mentioned embodiments only express several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but should not be construed as limiting the patent scope of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention should be based on the appended claims.
