Description

Technical Field

[0001] This utility model relates to the field of bathroom door design, and in particular to a convenient adjustment mechanism with pulleys. Background Technology

[0002] Bathroom doors are an important home furnishing component that separates the bathroom space from the outside environment, serving functions such as privacy protection, wet and dry separation, and decorative enhancement. Many modern bathroom doors use a lateral sliding mechanism for opening and closing. Specifically, the bathroom door is connected to a pulley mechanism, and the door frame has a track. The lateral movement of the bathroom door is achieved by the pulleys on the pulley mechanism moving along the track.

[0003] However, in actual bathroom door configuration, it was found that due to the presence of certain errors in the manufacturing of bathroom doors or pulley mechanisms, as well as assembly errors during assembly, the relative height of the pulleys on the bathroom door and pulley mechanism often does not meet expectations. This prevents the pulleys from effectively cooperating with the track on the door frame. In such cases, users often need to disassemble and reassemble the bathroom door and pulley mechanism to adjust their relative height, which is difficult, time-consuming, and laborious. Utility Model Content

[0004] The purpose of this utility model is to provide a convenient pulley adjustment mechanism that can solve one or more of the above-mentioned problems.

[0005] According to one aspect of this utility model, a convenient pulley adjustment mechanism is provided, comprising a pulley, a pulley seat, a door connecting block, an adjusting slider, and an adjusting screw. The pulley is rotatably mounted on a pulley seat, the pulley seat having a receiving cavity, and the receiving cavity having a longitudinal track and a transverse track. Both the door connecting block and the pulley seat are located within the accommodating cavity. The door connecting block is slidably mounted on the longitudinal track, and the adjusting slider is slidably mounted on the transverse track. The door connecting block has a groove, and the inner wall of the groove has a first inclined surface. One end of the adjusting slider has a protrusion, and the protrusion has a second inclined surface. The protrusion extends into the groove, and the first and second inclined surfaces abut against each other. The adjusting screw is threaded onto the pulley seat, and one end of the adjusting screw can extend into the receiving cavity. The adjusting screw can be rotated to change the amount of its insertion into the receiving cavity. As the insertion depth of the adjusting screw within the accommodating cavity increases, the adjusting screw abuts against the adjusting slider to drive the adjusting slider to move, and the door connecting block is correspondingly moved by the abutment of the first and second inclined surfaces. When the insertion amount of the adjusting screw into the accommodating cavity decreases, the door connecting block moves under the action of gravity, and the adjusting slider moves accordingly due to the abutment of the first inclined surface and the second inclined surface until the adjusting slider abuts against the adjusting screw.

[0006] The beneficial effects of this utility model are as follows: In this utility model, the door connecting block can be used to connect with the bathroom door, and the pulley can be set on the track of the door frame, thereby facilitating the movement of the bathroom door and realizing the opening and closing of the bathroom door. When the relative height between the bathroom door and the pulley is not as expected, the user can rotate the adjusting screw to move the adjusting screw. Due to the abutting cooperation of the first and second inclined surfaces, the adjusting slider and the door connecting block will move accordingly. The movement of the door connecting block can realize the adjustment of the relative height between the pulley and the bathroom door to better adapt to the assembly requirements. This utility model has low difficulty and convenience in adjusting the relative height between the pulley and the bathroom door, and the adjustment reliability is high.

[0007] In some embodiments, a vertical groove is provided on the side wall of the longitudinal track, and a first guide block is provided on the side of the door connecting block. The first guide block is slidably disposed on the vertical groove. The vertical groove can limit and guide the movement of the first guide block, thereby further ensuring that the door connecting block can only move longitudinally.

[0008] In some embodiments, a transverse groove is provided on the side wall of the transverse track, and a second guide block is provided on the side of the adjusting slider. The second guide block is slidably disposed on the transverse groove. The transverse groove can limit and guide the movement of the second guide block, thereby further ensuring that the adjusting slider can only move laterally.

[0009] In some embodiments, the door connecting block has a boss with a connecting hole and a recess. The boss is used for connection with the bathroom door, the connecting hole facilitates the connection with the bathroom door's connecting screws, and the recess increases the contact area between the boss and the bathroom door, thereby improving the reliability of the connection.

[0010] In some embodiments, the pulley seat includes a pulley seat body and a cover block. The pulley seat body is provided with a positioning post, and the cover block is provided with a hole. The cover block is connected to the pulley seat body and surrounds an accommodating cavity, and the positioning post is embedded in the hole.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] refer to Figures 1-5 The present invention provides a convenient adjustment mechanism for a pulley, comprising a pulley 1, a pulley seat 2, a door connecting block 3, an adjusting slider 4, and an adjusting screw 5.

[0021] The pulley seat 2 includes a pulley seat body 21 and a cover block 22. The pulley seat body 21 is provided with positioning posts 211, and the cover block 22 is provided with holes 221. There can be multiple positioning posts 211 and holes 221. In this embodiment, there are two positioning posts 211 and two holes 221. The cover block 22 is connected to the pulley seat body 21 by screws, and the two positioning posts 211 are embedded in the two holes 221 to ensure the accurate positioning of the cover block 22 on the pulley seat body 21.

[0022] The connected cover block 22 and pulley seat body 21 will form a receiving cavity, that is, the pulley seat 2 has a receiving cavity, and the receiving cavity has a longitudinal track 10 and a transverse track 20. The longitudinal track 10 is set perpendicular to the horizontal plane, and the transverse track 20 is set parallel to the horizontal plane.

[0023] Both the door connecting block 3 and the pulley seat 2 are located inside the accommodating cavity.

[0024] The door connecting block 3 is slidably mounted on the longitudinal track 10, meaning that the door connecting block 3 can slide along the longitudinal track 10. The longitudinal track 10 has a vertical groove 101 on its side wall, which is also perpendicular to the horizontal plane. The side of the door connecting block 3 has a first guide block 31, which is slidably mounted on the vertical groove 101 to further ensure that the door connecting block 3 can only move longitudinally. The vertical groove 101 can limit the maximum distance that the door connecting block 3 can move.

[0025] The adjusting slider 4 is slidably mounted on the transverse track 20, meaning that the adjusting slider 4 can slide along the transverse track 20. The transverse track 20 has a transverse groove 201 on its side wall, which is also parallel to the horizontal plane. The adjusting slider 4 has a second guide block 41 on its side, which is slidably mounted on the transverse groove 201 to further ensure that the adjusting slider 4 can only move laterally. The transverse groove 201 can limit the maximum distance that the adjusting slider 4 can move.

[0026] The door connecting block 3 is provided with a groove 32, and the inner wall of the groove 32 is provided with a first inclined surface 321. One end of the adjusting slider 4 is provided with a protrusion 42, and the protrusion 42 is provided with a second inclined surface 421. The protrusion 42 extends into the groove 32, and the first inclined surface 321 and the second inclined surface 421 abut against each other. When the adjusting slider 4 moves relative to the door connecting block 3, the second inclined surface 421 and the first inclined surface 321 can slide relative to each other.

[0027] The pulley seat body 21 is also provided with a protrusion 212, and the cover block 22 is also provided with a positioning groove 222. After the cover block 2 is placed on the pulley seat body 21, the protrusion 212 is embedded in the positioning groove 222. The protrusion 212 is also provided with a screw hole 213, and the adjusting screw 5 is provided on the screw hole 213. That is, the adjusting screw 5 is installed on the pulley seat 2 by thread engagement. One end of the adjusting screw 5 extends into the receiving cavity, and this end can abut against the other end of the adjusting slider 4 when needed. The adjusting screw 5 can rotate on the screw hole 213, thereby changing the amount of insertion of the adjusting screw 5 into the receiving cavity.

[0028] In addition, since the center line of the screw hole 213 is inclined downward relative to the horizontal plane, the adjusting screw 5 provided on the screw hole 231 is also inclined downward relative to the horizontal plane.

[0029] The bottom of the door connecting block 3 is also provided with a boss 33, a connecting hole 331 is provided in the boss 33, and a recess 332 is also provided on the boss 33.

[0030] The pulley 1 is rotatably mounted on the pulley seat 2. Preferably, the side of the pulley seat 2 is provided with a protrusion 23, and the pulley 1 is rotatably sleeved on the protrusion 23. Alternatively, the pulley 1 is mounted on the pulley seat 2 via a rotating shaft.

[0031] When in use, the door connecting block 3 can be connected to the bathroom door. Specifically, the boss 33 can be embedded in the bathroom door, and the connecting hole 331 on the boss 33 can be fitted with a bolt, which can also be connected to the bathroom door, thereby achieving a fixed connection between the door connecting block 3 and the bathroom door.

[0032] In this embodiment, the convenient adjustment mechanism of the pulley can be installed above the bathroom door and parallel to the horizontal plane. The pulley 21 can be installed on the track of the door frame and can move along the track of the door frame to move the bathroom door accordingly to realize the opening and closing of the bathroom door.

[0033] When the relative height between the pulley 21 and the bathroom door exceeds expectations, resulting in situations such as the pulley 21 being unable to be installed on the door frame track, the user can use tools such as a screwdriver to turn the adjusting screw 5, thereby changing the amount of insertion of the adjusting screw 5 into the receiving cavity, and thus changing the position of the door connecting block 3.

[0034] Specifically, when the adjusting screw 5 moves away from the adjusting slider 4, that is, when the insertion amount of the adjusting screw 5 in the accommodating cavity decreases, the door connecting block 3 can move down along the longitudinal track 10 under the action of gravity. Since the first inclined surface 321 and the second inclined surface 421 abut against each other, the downward movement of the door connecting block 3 can correspondingly drive the adjusting slider 4 to move backward along the transverse track 20 away from the door connecting block 3 until the adjusting slider 4 abuts against the adjusting screw 5. When the adjusting screw 5 moves towards the adjusting slider 4, that is, when the insertion amount of the adjusting screw 5 in the accommodating cavity increases, the adjusting screw 5 can abut against the adjusting slider 4 to drive the adjusting slider 4 to move forward along the transverse track 20 towards the door connecting block 3. Since the first inclined surface 321 and the second inclined surface 421 abut against each other, the forward movement of the slider 4 can drive the door connecting block 3 to move upward along the longitudinal track 10.

[0035] Users can move the door connecting block 3 up or down as needed by rotating the adjusting screw 5, thereby allowing the bathroom door to move up or down relative to the pulley 21. This effectively changes the relative height of the pulley 21 and the bathroom door to better match the track setting of the door frame. This utility model has low difficulty and convenience in adjusting the relative height of the pulley 21 and the bathroom door, and the adjustment reliability is high.

[0036] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
