Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a novel quick-install pulley. Background Art

[0002] The door of the shower room can move horizontally relative to the bracket. In order to improve the movement stability, a pulley is connected to the door.

[0003] When the pulley on the door contacts the bracket, the friction resistance is relatively small, so the door can move smoothly along the bracket.

[0004] The existing pulley is usually directly movably connected to the door, and the installation position on the door is limited, which makes it difficult to connect the pulley to the door, and the excessive exposure of the pulley makes its structure not compact. Summary of the invention

[0005] The utility model aims to solve the above problems in the prior art and provide a novel quick-install pulley which is convenient to load and unload and has a compact structure.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A new type of quick-release pulley is characterized in that it includes a connecting seat, a wheel seat and a roller. The connecting seat is block-shaped and has a concave positioning notch at the bottom. The wheel seat is long and connected to the side of the connecting seat. There are several rollers, which are evenly distributed along the length direction of the wheel seat and connected to the wheel seat.

[0008] The novel quick-install pulley creatively arranges a positioning notch on the connecting seat, and at the same time, a plurality of rollers are stably connected to the side of the connecting seat through the wheel seat.

[0009] The positioning notch can be snap-fitted and connected to the door panel of the shower room, and the structure can eventually stably connect the entire pulley to the door panel.

[0010] The arrangement of multiple rollers can enable the door panel to be stably slidably connected to the bracket of the shower room, ensuring that the door panel can be stably translated along the bracket.

[0011] In the above-mentioned new quick-release pulley, the connecting seat includes a main body, a snap-fit ​​plate and a connecting plate. The above-mentioned main body is block-shaped, and the above-mentioned snap-fit ​​plate is arranged adjacent to the inner side of the main body. The two ends of the above-mentioned connecting plate are respectively fixedly connected to the upper end of the main body and the upper end of the snap-fit ​​plate. The inner side of the main body, the snap-fit ​​plate and the connecting plate form the above-mentioned positioning recess with the opening facing downward.

[0012] The two ends of the connecting plate are respectively connected to the main body and the buckle plate. Such a structure can stably connect the buckle plate and the main body together and ensure that there is an appropriate distance between the buckle plate and the main body.

[0013] In the above-mentioned novel quick-release pulley, the outer side of the body has a recessed connecting cavity, the side of the wheel seat has a protruding positioning portion that matches the connecting cavity, the positioning portion is embedded in the connecting cavity and the two are fixedly connected.

[0014] After the positioning part is embedded in the connection cavity, the wheel seat and the body can be stably connected.

[0015] In the above-mentioned novel quick-release pulley, the outer side of the body has a protruding upper limit edge and a lower limit edge, the upper limit edge and the lower limit edge are adjacent to each other vertically, and the connecting cavity is located between the upper limit edge, the lower limit edge and the outer side of the body.

[0016] Since the positioning portion is located between the upper limit edge and the lower limit edge, the wheel seat can be stably connected to the outer side of the body in the end.

[0017] The novel quick-release pulley further comprises a fastener, which is sequentially passed through and connected to the lower limit edge, the positioning portion and the upper limit edge.

[0018] The wheel seat and the body can be stably fixed together under the action of the fastener.

[0019] In the above-mentioned novel quick-release pulley, the positioning portion is located in the middle of the wheel seat.

[0020] Such a structure can improve the structural compactness of the entire pulley.

[0021] In the above-mentioned novel quick-release pulley, the number of the rollers is two, and the two rollers are movably connected at the two ends of the wheel seat respectively.

[0022] Such a structure can balance the forces at both ends of the pulley and ensure its stability.

[0023] In the above-mentioned new quick-release pulley, one end of the connecting plate is hinged to the upper part of the main body, and the other end of the connecting plate is fixedly connected to the buckle plate. It also includes a connecting rod, the inner end of the connecting rod is axially fixed to the buckle plate, and the other end of the connecting rod is threadedly connected to the main body.

[0024] Such a structure can stably hinge the connecting plate to the main body. At the same time, under the action of the connecting rod, the main body and the connecting plate can be stably fixedly connected.

[0025] In the above-mentioned novel quick-release pulley, the upper part of the main body has two protruding hinged parts, and the end of the above-mentioned connecting plate is hinged between the two hinged parts.

[0026] The two hinged parts can stably hinge the connecting plate on the main body.

[0027] Compared with the prior art, the novel quick-release pulley can not only stably connect the wheel seat and the body together, but also facilitates the assembly and disassembly of the wheel body and the body, so it has high stability and is convenient for assembly and disassembly.

[0028] At the same time, since the connecting seat has a recessed positioning notch, the entire pulley can be stably connected to the bracket of the shower door under the action of the positioning notch, and its installation is relatively convenient. Since multiple rollers are in contact with the bracket of the shower room, the friction resistance is effectively reduced under the action of the pulley, ensuring that the shower door can be smoothly pushed.
