DETAILED DESCRIPTION
[0025] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0026] Refer to the instruction manual Figures 1-9 A damping pulley assembly that is easy to disassemble includes a buffer 1, and a head hanging pulley 3 and a tail hanging pulley 2 are respectively installed at both ends of the buffer 1.
[0027] like Figure 1 、 Figure 2 and Figure 6 As shown, the head hanging pulley 3 includes a front fixing member 31, which is installed at the end of the buffer 1. The front bottom body 32 is detachably connected to the front fixing member 31. Front side bodies 33 are installed on both sides of the front bottom body 32. Pulley three 330 is installed on the side away from each other of the two front side bodies 33. The front side bodies 33 are slidably installed on the front bottom body 32 along the length direction of the front bottom body 32.
[0028] Specifically, the front fixing member 31 is installed at the end of the buffer 1 by rivets, the front bottom body 32 is detachably installed on the front fixing member 31 by bolts, and two pulleys 330 are rotatably installed on each front side body 33.
[0029] Specifically, a second slide groove 321 is provided on the upper side of the front bottom body 32 near one end of the front fixing member 31 , and a protrusion 331 is provided at the bottom of the two front side bodies 33 . The two protrusions 331 are attached to each other and slidably installed in the front bottom body 32 .
[0030] Specifically, the two front side bodies 33 have an insert block 332 at one end close to the front fixing member 31 , and the front fixing member 31 has a socket 311 at one end close to the front bottom body 32 . The two insert blocks 332 are inserted into the socket 311 .
[0031] Furthermore, a positioning groove 333 is formed on one side of the bottom of the two front side bodies 33 that are close to each other, and the screws on the bottom of the front bottom body 32 are inserted into the interior of the positioning groove 333 .
[0032] During installation, first install two pulleys 330 on each front body 33, then bring the two front bodies 33 together, align the two protrusions 331 and insert them from one end of the second slide 321 into the interior of the second slide 321, then tighten the screws at the bottom of the front bottom body 32 so that the upper ends of the screws enter the positioning grooves 333 of the two front bodies 33, thereby positioning the front bodies 33 and preventing them from sliding out of the interior of the front bottom body 32. Next, dock the front bottom body 32 with the front fastener 31, that is, insert the two inserts 332 into the interior of the socket 311, and then use bolts to connect the front fastener 31 and the front bottom body 32. Finally, install the front fastener 31 at the end of the buffer 1 with rivets. To disassemble, just reverse the steps.
[0033] The above technical solution is achieved by setting up two front side bodies 33, and adopting a method of merging the two front side bodies 33 and then installing them on the front bottom body 32. During maintenance, there is no need to remove the rivets between the front fixing member 31 and the buffer 1. It is only necessary to remove the front bottom body 32 from the front fixing member 31, and then the pulley three 330 can be replaced, or other removed parts can be repaired and replaced, which is very convenient to operate.
[0034] like Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, the tail hanging pulley 2 includes a tail body 1 21, which is installed at the end of the buffer 1, and a tail body 2 22 is slidably installed in the length direction of the tail body 1 21. The tail body 1 21 and the tail body 2 22 are fixed by fasteners. A tail body 3 23 is vertically slidably installed on the tail body 2 22. The sides of the tail body 1 21 and the tail body 3 23 that are away from each other are respectively provided with a pulley 1 210 and a pulley 2 230, and a device for adjusting the height of the tail body 3 23 is installed on the tail body 2 22.
[0035] Specifically, the tail body 21 is mounted on the end of the buffer 1 by rivets.
[0036] Specifically, a fixing block 211 is provided on one side of the bottom of the tail body 1 21 in the longitudinal direction, and a sliding groove 220 is provided on one side of the tail body 22 . The sliding groove 220 is slidably installed with the fixing block 211 .
[0037] Specifically, an adjustment slot 221 is defined on one side of the second tail body 22 , and the third tail body 23 is vertically slidably installed in the adjustment slot 221 .
[0038] Furthermore, the device for adjusting the height of the tail body three 23 is an adjusting bolt 222 , which is rotatably connected to the bottom of the tail body two 22 , and the adjusting bolt 222 is threadedly connected to the bottom of the tail body three 23 .
[0039] During installation, first install pulley 230 and pulley 1 210 on tail body 3 23 and tail body 1 21, respectively. Next, insert adjustment bolt 222 from the bottom of tail body 2 22. To allow adjustment bolt 222 to be rotatably connected to tail body 2 22, a ring groove can be formed in adjustment bolt 222. A screw can then be inserted into the ring groove to position adjustment bolt 222. This allows adjustment bolt 222 to be rotatably connected to tail body 2 22. Then, install tail body 3 23 within adjustment groove 221. Rotate adjustment bolt 222 until adjustment bolt 222 is threadedly connected to tail body 3 23. Next, insert fixing block 211 into slide groove 1 220 and secure with a fastener, which can be a screw. Finally, install tail body 1 21 at the end of buffer 1 using rivets. For disassembly, reverse the steps.
[0040] The above technical solution enables the tail body 22 to be detachably mounted on the tail body 1 21, and the tail body 3 23 to be detachably mounted on the tail body 2 22. During maintenance, the tail body 2 22 and the tail body 3 23 can be removed from the tail body 1 21, thereby facilitating the maintenance and replacement of the disassembled related parts, and the operation is simple and convenient.
[0041] It is necessary to add that, if Figure 9 The figure shows a schematic diagram of the damping pulley assembly installed inside the slide rail 4. During use, the slide rail 4 is installed on the door frame, and the damping pulley assembly is installed inside the slide rail 4. During installation, the adjusting bolt 222 can be rotated to adjust the height of the tail body three 23, so that the pulley two 230 can be pressed against the top wall inside the slide rail 4, and the pulley one 210 can be pressed against the lower wall inside the slide rail 4, thereby ensuring that the tail hanging pulley 2 can be close to the upper and lower walls of the slide rail 4, and is relatively stable during movement without shaking, so that the noise of the damping pulley assembly during movement is reduced.
[0042] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
