Referring to fig. 1, an embodiment of the present utility model provides a pulley assembly 100, the pulley assembly 100 including a first shaft 105, a first mount 108, a second mount 103, a first wheel frame 102, and a first pulley 101. Wherein the first mount 108 is used for connecting with an object to be slid, for example, referring to fig. 5, the door 502 needs to slide relative to the guide rail 501, and then the door 502 can be connected with the first mount 108; the first pulley 101 is then adapted to be mounted on the guide rail 501.

Referring to fig. 1 and 2, the second mount 103 is rotatably connected to the first mount 108 through a first rotation shaft 105, the first wheel frame 102 is mounted on the second mount, and the first wheel frame 102 can rotate (or swing) with respect to the first mount along with the second mount. Referring to fig. 4, the second mount 103 has a plurality of first teeth 207, the first teeth 207 being distributed along the circumferential direction of the first rotation shaft 105, one end of the first wheel frame 102 having a plurality of second teeth 208, the first teeth 207 and the second teeth 208 being engaged with each other. When the first pulley 101 needs to swing, the first pulley 101, the first wheel frame 102, and the second mount 103 may swing together with respect to the first mount 108.

The working principle of the pulley assembly 100 is briefly described as follows.

As shown in fig. 5, the pulley assembly 100 is mounted on a door 502 and the first pulley 101 is mounted on a guide rail 501. Since a portion of the guide rail 501 is curved, during the movement of the first pulley 101 along the guide rail 501, the sidewall of the chute 903 may abut against the side of the first pulley 101 and drive the first pulley 101 to swing relative to the first mount 108 (one of the postures of the pulley assembly 100 after swinging may refer to fig. 6). During the swinging of the first pulley 101 relative to the first mount 108, the first wheel frame 102 and the first mount 108 remain engaged, but the position of engagement is slightly different.

Since the gear transmission has the characteristic of stable transmission, when the first pulley 101 swings relative to the first mounting seat 108, the swing of the first pulley 101 is stable. Therefore, the pulley assembly 100 of the present utility model makes the swing of the first pulley 101 smoother by providing the gear pair, thereby making the pulley assembly 100 smoother when sliding along the arc-shaped guide rail 501.

Other specific configurations of the pulley assembly 100 are described below.

Referring to fig. 1 and 2, in an embodiment, the first mount 108 may include a first clamp block 107, a second clamp block 106, and a threaded fastener 201, the first clamp block 107 including a first protrusion 303. Taking the first mounting seat 108 and the door 502 as an example, the first clamping block 107 and the second clamping block 106 can clamp the door 502 from two sides, the threaded fastener 201 is used for fixing the first clamping block 107 and the second clamping block 106 relatively, and the first protrusion 303 is used for realizing the mutual positioning between the first mounting seat 108 and the door 502. Specifically, referring to fig. 3, the first clamping block 107 has a first clamping surface 301, and the first teeth 207 may be disposed on the first clamping block 107 (the first teeth 207 are not specifically shown in fig. 3), and the second clamping block 106 has a second clamping surface 302, with the first clamping surface 301 and the second clamping surface 302 being opposite and spaced apart. The first clamping surface 301 and the second clamping surface 302 are spaced apart to form a receiving gap 110, and a portion of the door 502 may be disposed in the receiving gap 110, and the first clamping surface 301 and the second clamping surface 302 may be respectively attached to both sides of the door 502. The first clamping block 107 includes a first protrusion 303, the first protrusion 303 protruding with respect to the first clamping surface 301. Referring to fig. 3, the first protrusion 303 is located in the accommodation gap 110 and abuts against the second clamping block 106. The threaded fastener 201 may be a screw or bolt that passes through the second clamping block 106 and the first protrusion 303 to fix the first clamping block 107 and the second clamping block 106.

The portion of the door 502 located in the receiving space 110 may be provided with a mounting hole (the mounting hole is not specifically shown) in which the first protrusion 303 may be inserted, thereby achieving positioning between the first mount 108 and the door 502 and facilitating assembly between the pulley assembly 100 and the door 502. In addition, if the door 502 has a tendency to move relative to the first mount 108, the first protrusion 303 and the wall of the mounting hole may block each other, thereby restricting this relative movement; that is, first protrusion 303 also facilitates reducing the risk of first mount 108 being offset relative to door 502.

In one embodiment, the door 502 for connection with the first mount 108 is a glass door. In this case, in order to reduce damage to the door 502 and to improve connection stability of the first mount 108 to the door 502, a portion of the first clamping block 107 for contacting the door 502 and a portion of the second clamping block 106 for contacting the door 502 may be made of silicone rubber or other kinds of rubber.

For example, referring to fig. 3, the first clamping block 107 may include a first shell member 206 and a first spacer 205 connected to each other, and the second clamping block 106 includes a second shell member 203 and a second spacer 204 connected to each other, and the first spacer 205 and the second spacer 204 are made of silicone. The first clamping surface 301 is one of the side surfaces of the first shim 205, and the second clamping surface 302 is one of the side surfaces of the second shim 204. A portion of the first gasket 205 is sleeved outside the first boss 303, such portion of the first gasket 205 may be co-threaded with the first boss 303 in the mounting hole, and a portion of the first gasket 205 sleeved outside the first boss 303 may be in contact with the wall of the mounting hole.

The first protrusion 303 of the first clamping block 107 mentioned above may enable positioning between the first mount 108 and the door 502. In an embodiment, referring to fig. 3, the first clamping block 107 further has a second protrusion 304, and the second clamping block 106 further has a third protrusion 305, where the second protrusion 304 and the third protrusion 305 are used to abut against an edge of the door 502, so as to further improve the positioning effect between the first mounting seat 108 and the door 502.

Specifically, the second protrusion 304 is located at the top end or the bottom end of the first clamping block 107, and the second protrusion 304 protrudes with respect to the first clamping surface 301; the third protrusion 305 is located at the top or bottom end of the second clamping block 106, the third protrusion 305 is disposed opposite the second protrusion 304, and the third protrusion 305 is disposed opposite the second protrusion 304. By "the third protrusion 305 and the second protrusion 304 are disposed opposite to each other" it is meant that if the second protrusion 304 is located at the top end of the first clamping block 107, the third protrusion 305 is located at the top end of the second clamping block 106; if the second protrusion 304 is located at the bottom end of the first clamping block 107, the third protrusion 305 is located at the bottom end of the second clamping block 106.

If the first mount 108 is mounted on the bottom of the door 502, the second protrusion 304 may be located at the bottom end of the first clamping block 107, the third protrusion 305 is located at the bottom end of the second clamping block 106 (as shown in fig. 3), and the top of the second protrusion 304 and the top of the third protrusion 305 may abut against the bottom edge of the door 502, so as to achieve positioning between the first mount 108 and the door 502. Similarly, if the first mount 108 is mounted on top of the door 502, the second protrusion 304 may be located at the top end of the first clamping block 107, the third protrusion 305 may be located at the top end of the second clamping block 106, and the second protrusion 304 and the third protrusion 305 abut against the top edge of the door 502, thereby achieving positioning between the first mount 108 and the door 502.

Referring to fig. 1 and 2, in an embodiment, the pulley assembly 100 further includes a screw 104, the screw 104 is connected to the second mount 103 and fixed with respect to the second mount 103, the first wheel frame 102 is screwed with the screw 104, the screw 104 is vertically disposed and parallel to the first rotation shaft 105, and the second teeth 208 are distributed along a circumferential direction of the screw 104 (as shown in fig. 4). In the case that the first wheel frame 102 does not rotate or has small rotation amplitude relative to the screw 104, the threaded fit between the first wheel frame 102 and the screw 104 can limit the up-and-down movement of the first wheel frame 102, thereby limiting the up-and-down movement of the first pulley 101 and improving the stability of the first pulley 101 in the movement process.

Referring to fig. 4, in an embodiment, the first wheel frame 102 has a limiting surface 307, and the limiting surface 307 may abut against the second mount 103 and restrict the rotation angle of the first wheel frame 102 relative to the screw 104. Specifically, referring to fig. 4, each of both sides of the first wheel frame 102 has a limiting surface 307, the limiting surfaces 307 are provided as a plane, a normal line of the limiting surfaces 307 is perpendicular to an axis of the screw 104, the second mounting seat 103 has a receiving groove 306, and at least a part of the limiting surfaces 307 is provided in the receiving groove 306. The stopper surface 307 can abut against the wall surface of the accommodating groove 306 to prevent the first wheel carrier 102 from rotating relative to the second mounting seat 103.

Because the first wheel frame 102 is in threaded connection with the screw 104, the limiting surface 307 is arranged to limit the rotation angle of the first wheel frame 102, so that the up-down movement range of the first wheel frame 102 and the first pulley 101 can be limited, and the movement stability of the first pulley 101 is enhanced.

In some usage scenarios, the pulley assemblies 100 are mounted on both the upper and lower ends of the door 502 (two guide rails 501 are correspondingly provided), the pulley assemblies 100 at the top and bottom ends of the door 502 may be configured as shown in fig. 1, and the pulley assemblies 100 at the bottom end of the door 502 may be configured as shown in fig. 7. If the pulley assembly 100 at the bottom end of the door 502 is configured as shown in fig. 7, the convenience of assembly and disassembly between the pulley assembly 100 at the bottom end and the guide rail 501 is improved.

The pulley assembly 100 shown in fig. 7 is described below.

Referring to fig. 7 to 9, the pulley assembly 100 includes a second rotation shaft 703, a third mount 701, a fourth mount 702, a compression bar 704, a second wheel frame 706, a second pulley 705, and an elastic member 901. Referring to fig. 8, the third mount 701 and the fourth mount 702 are rotatably coupled by a second rotation shaft 703, and the third mount 701 has a plurality of third teeth 803, and the third teeth 803 are distributed along the circumferential direction of the second rotation shaft 703. Referring to fig. 9, the compression bar 704 is movably connected with the fourth mount 702, and the compression bar 704 can be lifted relative to the fourth mount 702; the fourth mounting seat 702 and the compression bar 704 are connected with the elastic piece 901, and the elastic force of the elastic piece 901 is used for driving the compression bar 704 to move upwards to reset. Referring to fig. 8, the second wheel frame 706 is coupled to the compression bar 704, one end of the second wheel frame 706 has a plurality of fourth teeth 804, the fourth teeth 804 are distributed along the circumferential direction of the compression bar 704, and the fourth teeth 804 are engaged with the third teeth 803; a second pulley 705 is mounted at the other end of the second wheel frame 706.

The pulley assembly 100 shown in fig. 7, the third mount 701 may be used to connect with the door 502, and the specific structure of the third mount 701 may be the structure of the first mount 108 mentioned above, which is not described in detail herein. The pulley assembly 100 shown in fig. 7 can also improve the smoothness of the swing of the second pulley 705 by using a gear transmission, thereby improving the smoothness of the motion of the pulley assembly 100 along the guide rail 501.

While the combination of the compression bar 704 and the elastic member 901 may, on the one hand, make the second pulley 705 more tightly fit with the guide rail 501 and, on the other hand, may facilitate the installation or removal of the pulley assembly 100 from the guide rail 501. Specifically, referring to fig. 9, the elastic member 901 may be in a compressed state, and the second pulley 705 may drive the second pulley 705 to move upward under the elastic force of the elastic member 901. Referring to fig. 10 or 11, the second pulley 705 is pressed up against the top wall of the chute 903 of the guide rail 501 by the elastic force of the elastic member 901, thereby making the fit between the second pulley 705 and the guide rail 501 tighter. Wherein, referring to fig. 11, when the second pulley 705 needs to be removed from the guide rail 501, the user can press the plunger 704 downward first, disengage the right side of the second pulley 705 from the guide rail 501, and then push the second pulley 705 out of the guide rail 501 rightward (keep pressing the plunger 704 before pushing). Similarly, when it is desired to load the second pulley 705 into the rail 501, the user may first press down on the plunger 704 and then move the second pulley 705 to the left and into the rail 501, after which the second pulley 705 is moved into the rail 501, the user releases the plunger 704 and the plunger 704 moves upward under the force of the spring 901 until it abuts against the top wall of the rail 501.

Referring to fig. 8 or 9, in an embodiment, the pressing bar 704 is vertically disposed, an outer circumferential surface of the pressing bar 704 is threaded, and the pressing bar 704 may be screwed with the second wheel frame 706. Similar to the threaded engagement between the screw 104 and the first wheel frame 102, the threaded engagement between the plunger 704 and the second wheel frame 706 may limit the up-and-down movement of the second wheel frame 706, thereby improving the movement stability of the second pulley 705.

In addition, in order to limit the rotation angle of the second wheel frame 706 relative to the fourth mounting seat 702, two sides of the second wheel frame 706 may also be provided with limiting surfaces 307. The limit fit between the second wheel frame 706 and the fourth mount 702 may be referred to as the limit fit between the first wheel frame 102 and the second mount 103 described above, and the description thereof will not be repeated here.

The manner of mounting the elastic member 901 will be described in detail. Referring to fig. 9, the fourth mount 702 has a housing chamber 902, and an elastic member 901 is provided in the housing chamber 902, with the bottom end of the elastic member 901 abutting against the bottom wall of the housing chamber 902. The plunger 704 includes a ram 801 and a connecting rod 802, both of which are slidable up and down relative to the fourth mount 702. The ram 801 is attached to the top end of the tie bar 802, and the ram 801 protrudes with respect to the side of the tie bar 802 (e.g., the ram 801 has a diameter greater than the diameter of the tie bar 802). The bottom surface of the ram 801 is located in the accommodating chamber 902 and abuts against the top end of the elastic member 901, a portion of the connecting rod 802 is located in the accommodating chamber 902, and the elastic member 901 is sleeved outside the portion of the connecting rod 802 located in the accommodating chamber 902. The bottom end of the connecting rod 802 is located outside the receiving cavity 902, and the second wheel frame 706 is connected to the bottom end of the connecting rod 802.
