[0032] Combine the following Figures 1 to 5 , describing a pull rod assembly that can be adjusted at multiple angles according to an embodiment of the utility model.

[0033] A multi-angle adjustable pull rod assembly comprises a pull rod 1 and a screen side rod 2; an axial hinge portion 3 is provided at the rear of the pull rod 1, a universal hinge portion 4 is provided at the front of the pull rod 1, a front end of the universal hinge portion 4 is movably connected to the screen side rod 2, and a rear end of the axial hinge portion 3 is fixed to a wall;

[0034] The axial hinge part 3 is used to make the pull rod 1 and the wall rotate axially relative to each other;

[0035] The universal hinge part 4 is used to make the pull rod 1 and the screen side rod 2 rotate relative to each other in a universal direction.

[0036] The utility model provides a preferred embodiment of a pull rod assembly that can be adjusted at multiple angles, such as Figures 1 to 5As shown, the screen side rod 2 on the window side is movably connected by the front end of the universal hinge 4, so that the front end of the pull rod 1 can move with the screen (such as a shower screen) by utilizing the relative universal rotation relationship, and at the same time, the front end of the pull rod 1 can move on the screen side rod 2 by utilizing the movable connection relationship, cooperate with the movement of the screen, and form a supporting force for the screen; when the relative position of the screen is determined, the rear end of the pull rod 1 is fixed to the wall by utilizing the relative axial rotation relationship of the axial hinge 3, so that the screen has the installation and debugging capabilities, can adapt to different screen installation positions, and after installation, the axial hinge 3 and the universal hinge 4 can be used to rotate in coordination to achieve fine-tuning of the screen position, making the screen more flexible to use.

[0037] Furthermore, the pull rod 1 includes a wall connector 11, a connecting middle rod 12 and a screen connector 13; the rear end of the wall connector 11 is fixed to the wall, the front part of the wall connector 11 and the rear end of the connecting middle rod 12 are hinged to form an axial hinge part 3, the front end of the connecting middle rod 12 and the rear part of the screen connector 13 are universally hinged to form a universal hinge part 4, and the front part of the screen connector 13 is movably connected to the screen side rod 2.

[0038] In this embodiment, because the pull rod 1 is to form an axial hinge part 3 and a universal hinge part 4 respectively, it is composed of three parts, namely a wall connector 11, a connecting middle rod 12 and a screen connector 13. The axial hinge part 3 is formed by hingedly connecting the front part of the wall connector 11 and the rear end of the connecting middle rod 12, and the universal hinge part 4 is formed by universally hingedly connecting the front end of the connecting middle rod 12 and the rear end of the screen connector 13.

[0039] Furthermore, the front end of the connecting middle rod 12 is set as a spherical hinge joint 121, and the rear part of the screen connecting member 13 is set as a fixable elastic spherical hinge groove; the spherical hinge joint 121 and the elastic spherical hinge groove are ball-hinged.

[0040] In the present embodiment, the universal hinge relationship of the universal hinge part 4 is achieved by setting the front end of the connecting middle rod 12 as a spherical hinge joint 121, and the rear part of the screen connecting part 13 as a fixable elastic spherical hinge groove, and the spherical hinge joint 121 and the elastic spherical hinge groove are ball-hinged. At the same time, when the spherical hinge joint 121 and the elastic spherical hinge groove rotate relative to each other, the elastic spherical hinge groove can also use its own elasticity to adapt to the spherical hinge joint 121, so that the elastic spherical hinge groove is always in contact with the spherical hinge joint 121, and after the rotation relationship between the two is determined, the size of the elastic spherical hinge groove at this time is fixed to achieve a relative fixed relationship between the two, so that the pull rod 1 no longer moves with the screen, and a supporting force is formed on the screen.

[0041] Furthermore, the screen connecting member 13 includes a hinge groove fixing member 135, a connecting body 132, a hinge groove upper cover 133 and at least one elastic member 134; a lower hemispherical groove 1321 is formed at the upper rear portion of the connecting body 132, and an upper hemispherical groove 1331 is formed at the lower portion of the hinge groove upper cover 133 corresponding to the lower hemispherical groove 1321;

[0042] The hinge slot upper cover 133 is disposed above the upper rear portion of the connecting body 132, and the elastic member 134 is disposed between the hinge slot upper cover 133 and the upper rear portion of the connecting body 132. The elastic member 134, the upper hemispherical slot 1331 and the lower hemispherical slot 1321 are surrounded to form an elastic spherical hinge slot;

[0043] The hinge slot fixing member 135 connects the hinge slot upper cover 133 and the upper rear portion of the connecting body 132 , and is used to fix the relative position relationship between the hinge slot upper cover 133 and the upper rear portion of the connecting body 132 .

[0044] In this embodiment, the hinge slot upper cover 133 is arranged above the upper rear part of the connecting body 132, and the elastic member 134 is arranged between the hinge slot upper cover 133 and the upper rear part of the connecting body 132. The elastic member 134, the upper hemispherical slot 1331 and the lower hemispherical slot 1321 together form an elastic spherical hinge slot, so that the elastic member 134 is used to make the degree of closing between the hinge slot upper cover 133 and the connecting body 132 elastic, and the degree of closing can be adjusted by rotating the spherical hinge head 121. Finally, the relative position relationship (degree of closing) between the hinge slot upper cover 133 and the upper rear part of the connecting body 132 is fixed by the hinge slot fixing member 135, so that the size of the elastic spherical hinge slot is fixed, and the rotation of the spherical hinge head 121 is restricted, thereby realizing the elastic change and fixable function of the elastic spherical hinge slot.

[0045] Furthermore, the hinge slot fixing member 135 is a screw, and a threaded fixing through hole 1332 is opened on the circumferential side of the hinge slot upper cover 133, and a threaded fixing groove 1325 is opened at the rear upper part of the connecting body 132 corresponding to the threaded fixing through hole 1332, and the tail end of the screw is threadedly connected through the threaded fixing through hole 1332 and is threadedly connected to the threaded fixing groove 1325.

[0046] In the present embodiment, in order to be able to fix the relative position relationship between the hinge slot upper cover 133 and the rear upper part of the connecting body 132 by means of the hinge slot fixing member 135, it is preferred that the hinge slot fixing member 135 is set as a screw, and a threaded fixing through hole 1332 is opened on the circumferential side passing through the hinge slot upper cover 133, and a threaded fixing groove 1325 is opened at the rear upper part of the connecting body 132 corresponding to the threaded fixing through hole 1332, and the tail thread of the screw passes through the threaded fixing through hole 1332 and is threadedly connected to the threaded fixing groove 1325.

[0047] Furthermore, the elastic member 134 is a spring, a first spring limiting groove 1333 is provided on the peripheral side of the hinge slot upper cover 133, a second spring limiting groove 1326 is provided on the rear upper part of the connecting body 132 corresponding to the first spring limiting groove 1333, one end of the spring is limited in the first spring limiting groove 1333, and the other end of the spring is limited in the second spring limiting groove 1326;

[0048] The number of the first spring limiting grooves 1333 and the second spring limiting grooves 1326 is the same as the number of the elastic members 134 .

[0049] In this embodiment, in order to achieve elastic closing between the hinge slot upper cover 133 and the rear upper part of the connecting body 132, the elastic member 134 is preferably a spring. In order to limit the spring, a first spring limiting groove 1333 is opened on the peripheral side of the hinge slot upper cover 133, and a second spring limiting groove 1326 is opened at the rear upper part of the connecting body 132 corresponding to the first spring limiting groove 1333, so that one end of the spring is limited in the first spring limiting groove 1333, and the other end of the spring is limited in the second spring limiting groove 1326.

[0050] Furthermore, an embedding groove 21 is provided on the rear side of the screen side rod 2 from top to bottom, and the front part of the screen connecting member 13 can be embedded in the embedding groove 21 .

[0051] In this embodiment, the movable connection relationship between the pull rod 1 and the screen side rod 2 is preferably an up and down sliding relationship to cater to the characteristics of the screen side rod 2. Therefore, a groove 21 is opened from top to bottom on the back of the screen side rod 2, so that the front part of the screen connecting piece 13 can be embedded in the groove 21 and can be fixed after sliding up and down.

[0052] Furthermore, a limit seat 1322 is provided at the front end of the connecting body 132, and an insert block 1323 with multiple bends is provided in front of the limit seat 1322.

The front of the limit seat 1322 and the back of the screen side rod 2 are against each other.

[0053] In this embodiment, in order to make the front part of the screen connecting member 13 more firmly fixed after sliding up and down in the embedding groove 21, and not easily displaced by external force, a limit seat 1322 is preferably provided at the front end of the connecting body 132, and an embedding block 1323 with multiple bends is provided in front of the limit seat 1322, and then a special-shaped groove 211 is formed in the embedding groove 21 corresponding to the embedding block 1323, so that after the embedding block 1323 is embedded in the special-shaped groove 211 and slides up and down, the multiple bends of the embedding block 1323 cooperate with the special-shaped groove 211, and the fixing relationship between the two is more firmly. At the same time, the front of the limit seat 1322 also abuts against the back of the screen side rod 2, which not only increases the friction force but also prevents the connecting body 132 from being offset.

[0054] Furthermore, the limiting seat 1322 is provided with a fixing through hole 1324 , and the tail of the fixing member 5 can pass through the fixing through hole 1324 and be fixed to the back of the screen side rod 2 .

[0055] In this embodiment, in order to further fix the relative position relationship between the pull rod 1 and the screen side rod 2 after sliding, so that the pull rod 1 can provide stronger support for the screen side rod 2, a fixing through hole 1324 (such as a threaded hole) is opened in the limit seat 1322, and the tail of the fixing part 5 (such as a screw) can be passed through the fixing through hole 1324 and fixed to the back of the screen side rod 2, thereby limiting the sliding of the insert 1323 in the special-shaped groove 211.

[0056] Furthermore, the rear end of the connecting middle rod 12 is set as a first hinge joint 122, the front part of the wall connecting member 11 is set as a second hinge joint 111, and the first hinge joint 122 and the second hinge joint 111 are hinged;

[0057] The rear part of the wall connecting member 11 is a seat body 112 which is perpendicular to the second hinge joint 111 , and the rear part of the seat body 112 is fixed to the wall.

[0058] In this embodiment, the axial rotation relationship of the axial hinged portion 3 is achieved by setting the rear end of the connecting middle rod 12 as a first hinged joint 122, and the front part of the wall connecting member 11 as a second hinged joint 111. The first hinged joint 122 and the second hinged joint 111 are hinged, and then fixed to the wall through the back of the seat body 112, thereby transmitting the supporting force of the wall to the screen side rod 2.
