[0024] Reference Figures 1 to 17 This application provides a telescopic bracket assembly fixture. When assembling a telescopic bracket, the assembly fixture is used to assist in improving the assembly efficiency between various components and modules in the telescopic bracket.

[0025] The telescopic bracket assembled using this assembly fixture can be applied to automatic clothes drying racks, wall-mounted drying racks (such as wall-mounted clothes racks or wall-mounted towel racks), floor-standing drying racks, and garment care machines.

[0026] Figure 1 The diagram illustrates the structure of the assembly fixture 50 of this application. Figures 5 to 11 This is a process diagram showing the application of the assembly fixture 50 to the telescopic bracket 200. Figures 12 to 17 The telescopic bracket 200 shown in the figure can be assembled using the assembly fixture 50 of this application.

[0027] To facilitate understanding of the assembly jig 50 and the principle of improving assembly efficiency during the assembly of the telescopic bracket 200, the structure of the telescopic bracket 200 that can be assembled using the assembly jig 50 of this application will be explained below.

[0028] like Figure 15 The telescopic bracket 200, as illustrated, includes a bracket body 10, a first transmission assembly 20, and a slide rail assembly 30. The first transmission assembly 20 includes at least one input gear 21 (the number of input gears 21 can be set to one, two, or more depending on transmission requirements), each input gear 21 being rotatably mounted on the bracket body 10. The slide rail assembly 30 includes at least a telescopic frame 31, which is slidably disposed on the bracket body 10. After assembly, the first transmission assembly 20 and the slide rail assembly 30 are connected in a transmission manner, so that the power output from the input gears 21 in the first transmission assembly 20 to the slide rail assembly 30 can drive the telescopic frame 31 to slide relative to the bracket body 10.

[0029] Continue to refer to Figures 13 to 17 The bracket body 10 serves as the supporting foundation for the telescopic bracket 200. When the telescopic bracket 200 is used in a clothes drying rack, the bracket body 10 is connected to the main unit 100 of the clothes drying rack via a lifting assembly; when the telescopic bracket 200 is used in a wall-mounted drying rack, the bracket body 10 is installed on a vertical mounting surface such as a wall.

[0030] The first transmission assembly 20 and the slide rail assembly 30 are adapted to be assembled inside the bracket body 10, and are arranged along the transverse direction, i.e., the width direction, of the bracket body 10. The slide rail assembly 30 is configured such that at least a portion of its structure can receive the power transmitted by the input gear 21 in the first transmission assembly 20, and reciprocates along the length direction of the bracket body 10 under the drive of the first transmission assembly 20. Exemplarily, the bracket body 10 has a first mounting cavity 101 and a second mounting cavity 102 inside, the first transmission assembly 20 is installed in the first mounting cavity 101, and the slide rail assembly 30 is installed in the second mounting cavity 102. A top opening 103 communicating with the first mounting cavity 101 is provided on one side of the bracket body 10, and an end opening 104 communicating with the second mounting cavity 102 is provided at least one end. Optionally, the bracket body 10 divides its inner cavity into a first mounting cavity 101 and a second mounting cavity 102 by an internal partition 11. The partition 11 is provided with a mating through hole so that the first transmission assembly 20 and the slide rail assembly 30 can engage in transmission through the mating through hole. Figure 11 When the slide rail assembly 30 is continuously pushed, the telescopic frame 31 can engage with the input gear 21. In other embodiments, the partition 11 may not be provided inside the bracket body 10.

[0031] In one embodiment, when the telescopic bracket 200 is applied to a clothes drying rack, the main unit 100 of the clothes drying rack is connected to the bracket body 10 of the telescopic bracket 200 via a lifting assembly, and the drying rod 500 is connected to the telescopic bracket 200. The lifting assembly can drive the telescopic bracket 200 and the drying rod 500 to rise and fall to a suitable height. When it is necessary to adjust the position of the drying rod 500, an external driving force (such as motor power, manually applied force, or force generated in conjunction with lifting or other movements) can be applied to the first transmission assembly 20 to rotate the input gear 21 in the first mounting cavity 101. Since the first transmission assembly 20 is connected to the slide rail assembly 30, the rotation of the input gear 21 can be converted into linear motion of the telescopic frame 31, driving the telescopic frame 31 to extend or retract from the end opening 104 of the second mounting cavity 102 of the bracket body 10. When the telescopic frame 31 extends, it can simultaneously unfold the clothes drying rod 500 of the clothes drying machine, expanding the drying area; when the telescopic frame 31 retracts, the clothes drying rod 500 is retracted, reducing the overall space occupied by the clothes drying machine.

[0032] In another embodiment, when the telescopic bracket 200 is applied to a wall-mounted drying rack, after the bracket body 10 is fixed to the wall, the input gear 21 of the first transmission component 20 is driven to rotate manually or electrically, and the telescopic frame 31 is also driven to slide along the bracket body 10 through the transmission cooperation. When the telescopic frame 31 is extended, it is convenient to hang towels, clothes and other objects on the telescopic frame 31 or on the drying rod 500 connected to the telescopic frame 31. When the telescopic frame 31 is retracted, the overall volume of the telescopic bracket 200 is reduced, avoiding the occupation of indoor activity space.

[0033] It should be noted that the telescopic bracket 200 can also be applied to other drying devices or home appliances. It receives power through the first transmission component 20 and transmits the power to the slide rail component 30, so as to realize the sliding of the telescopic bracket 31 relative to the bracket body 10, thereby satisfying the telescopic function.

[0034] Continue to refer to Figures 1 to 11 The following is a structural description of the assembly fixture 50 for the telescopic bracket 200 of this application.

[0035] The assembly fixture 50 includes a first assembly part 51 and a second assembly part 52, and the second assembly part 52 is connected to the first assembly part 51.

[0036] The first assembly part 51 has a bracket positioning structure 511 and at least one wheel positioning part 512. The bracket positioning structure 511 is used to position the bracket body 10 of the telescopic bracket 200. The number of wheel positioning parts 512 is the same as the number of input gears 21 in the first transmission assembly 20. For example, the number of wheel positioning parts 512 is one, two, or more. The wheel positioning parts 512 are used to position the input gears 21 in the first transmission assembly 20 of the telescopic bracket 200 so that the input gears 21 can be aligned with the wheel mounting parts 13 on the bracket body 10, thereby facilitating the rotatable mounting of the input gears 21 onto the wheel mounting parts 13 of the bracket body 10 by rotating the connecting member. The wheel mounting parts 13 can be shafts, grooves, holes, etc., as long as the input gears 21 can be rotatably connected to the bracket body 10 after being mounted on the wheel mounting parts 13.

[0037] The second assembly part 52 is provided with a guide structure 521, which extends toward the first assembly part 51. For example, the first assembly part 51 and the second assembly part 52 are arranged along the x-direction, and the guide structure 521 extends along the x-direction to provide guidance in the x-direction. The guide structure 521 is used to position the slide rail assembly 30 of the telescopic bracket 200 and guide the slide rail assembly 30 to slide along the guide structure 521 under the action of force to enter the installation position of the slide rail assembly 30 on the bracket body 10 of the first assembly part 51. After the slide rail assembly 30 is placed in the second assembly part 52 of the bracket body 10, it can slide along the guide structure 521 under the action of external force applied manually by the operator or by an electric device.

[0038] Based on the structure of the telescopic bracket 200 and the assembly fixture 50 described above, an assembly method for the telescopic bracket 200 is provided below as an example to illustrate the principle that the assembly fixture 50 can improve assembly efficiency. The assembly method for the telescopic bracket 200 includes: an assembly step of the first transmission component 20 and the bracket body 10, and an assembly arrangement of the slide rail component 30 and the bracket body 10.

[0039] The assembly steps of the first transmission component 20 and the bracket body 10 include: S11: As Figure 6 As shown, each input gear 21 in the first transmission assembly 20 is placed in the corresponding wheel positioning part 512 of the assembly fixture 50 (if there is one input gear 21, it is placed in one wheel positioning part 512; if there are two or more input gears 21, they are placed in different wheel positioning parts 512 respectively).

[0040] S12: As Figure 7The telescopic bracket 200 is placed on the bracket positioning structure 511 of the first assembly part 51 of the assembly fixture 50, and the two input gears 21 are aligned with the two wheel mounting parts 13 of the bracket body 10.

[0041] S13: As Figure 7 As shown, two input gears 21 are rotatably mounted to the two wheel mounting portions 13 of the bracket body 10 using a rotating connector, such as a shaft.

[0042] The assembly steps of slide rail assembly 30 and bracket body 10 include: S21: As Figures 9 to 10 The bracket body 10 is placed on the bracket positioning structure 511 of the first assembly part 51, and the slide rail assembly 30 is placed on the guide structure 521 of the second assembly part 52, so that the slide rail assembly 30 is aligned with the end opening 104 of one end of the second mounting cavity 102 of the bracket body 10.

[0043] S22: As Figure 10 Indication ( Figure 10 This includes the slide rail assembly 30 from its initial state to its state after being pushed into the bracket body 10. Pushing or pulling the slide rail assembly 30 applies a force towards the bracket body 10, allowing it to slide into the second mounting cavity 102 of the bracket body 10 through the end opening 104, guided by the guide structure 521, until the slide rail assembly 30 slides into place, completing the transmission engagement between the slide rail assembly 30 and the first transmission assembly 20. It should be noted that the bracket body 10 may also omit the second mounting cavity 102. In this step, the slide rail assembly 30 is pushed into a preset mounting area inside the bracket body 10, which is located beside the mounting area of ​​the first transmission assembly 20.

[0044] The telescopic bracket 200 assembly fixture 50 of this application, through the configuration of the first assembly part 51 and the second assembly part 52, has many advantages in the assembly process of the telescopic bracket 200: First, through the cooperation of the bracket positioning structure 511 and the wheel positioning part 512 of the first assembly part 51, the precise positioning of each input gear 21 and the bracket body 10 can be achieved during the assembly stage of the first transmission component 20 and the bracket body 10 (regardless of whether there is one, two or more input gears 21). This ensures that the wheel mounting part 13 on the bracket body 10 is quickly aligned with the mounting position of the input gear 21, effectively avoiding problems such as misalignment of mounting holes and tilting of gear installation caused by component positioning deviations in traditional manual assembly. This significantly improves the assembly accuracy of the first transmission component 20 and the bracket body 10, thereby ensuring the stability of the subsequent transmission cooperation between the first transmission component 20 and the slide rail component 30, and reducing potential faults such as sliding jamming of the telescopic frame 31 and transmission failure caused by assembly errors.

[0045] Secondly, the guide structure 521 of the second assembly part 52 can provide a clear sliding path for the slide rail assembly 30, guiding the slide rail assembly 30 smoothly into the second mounting cavity 102 of the bracket body 10 along a preset direction. It can achieve transmission docking with the first transmission assembly 20 without repeated manual adjustment of the angle and position of the slide rail assembly 30 (for example, at least one input gear 21 in the first transmission assembly 20 meshes with the rack or gear in the slide rail assembly 30 through the mating through hole of the partition 11), shortening the installation and debugging time of the slide rail assembly 30. At the same time, the guide structure 521 can also prevent the slide rail assembly 30 from colliding and wearing with the inner wall of the bracket body 10 during the assembly process.

[0046] Furthermore, the assembly fixture 50 integrates the assembly and positioning functions of the bracket body 10, the first transmission component 20, and the slide rail component 30 into one unit, enabling the assembly of the telescopic bracket 200 at the same workstation and improving assembly efficiency. It also helps to form orderly assembly steps, reduces the requirements for assembly personnel or electric assembly systems, helps achieve consistency in batch assembly, and is suitable for improving assembly efficiency and yield in large-scale production scenarios.

[0047] In one embodiment, reference is made to Figure 1 , Figure 2 To improve the application flexibility of the telescopic bracket 200 assembly fixture 50, the bracket positioning structure 511 includes a first positioning part 5111 and a second positioning part 5112. The first positioning part 5111 is used to position the bracket body 10 to assist the input gear 21 in assembling with the bracket body 10; the second positioning part 5112 is used to position the bracket body 10 to assist the slide rail assembly 30 in assembling with the bracket body 10.

[0048] It is understood that during the two processes of installing the first transmission assembly 20 and the slide rail assembly 30 onto the bracket body 10, the bracket body 10 can be positioned at the first positioning part 5111 and the second positioning part 5112 respectively, so that the bracket body 10 is in different areas of the first assembly part 51 of the fixture, and / or in different postures (e.g., the bracket body 10 is facing down or facing up). This makes it easier to meet the installation requirements during the installation of the first transmission assembly 20 and the slide rail assembly 30 onto the bracket body 10, and saves more effort.

[0049] By way of example only, the telescopic bracket 200 has a top and a bottom. When the telescopic bracket 200 is used in a drying scenario, the top of the telescopic bracket 200 is suspended from the clothes drying machine main unit 100 or the ceiling by connecting components 300 such as cables and scissor brackets. The telescopic bracket 200 has a top side opening 103. Inside the telescopic bracket 200, a drive component 400 (e.g., a slider hinged to the bottom of the scissor-mounted folding rod) is also provided. The drive component 400 is in transmission cooperation with the first transmission assembly 20. The lifting and lowering movements of the drive component 400 are linked to the lifting and lowering movements of the telescopic bracket 200. For example, during the lifting and lowering process of the telescopic bracket 200, the drive component 400 reciprocates along the length of the bracket body 10. This movement of the drive component 400 drives the input gear 21 in the first transmission assembly 20 to rotate. Furthermore, the clockwise or counterclockwise rotation of the input gear 21 drives at least some components of the slide rail assembly 30 (e.g., the telescopic frame 31) to extend or retract into the bracket body 10, thereby meeting the requirements for adjusting the position of the drying rod 500. At this time, the connecting assembly 300 needs to extend into the interior of the bracket body 10 through the top side opening 103 to cooperate with the drive component 400 or the first transmission assembly 20.

[0050] With a top side opening 103 provided at the top of the bracket body 10, the bottom of the bracket body 10 has a base plate 12. The input gear 21 in the first transmission assembly 20 can be configured to be rotatably mounted on the base plate 12. Therefore, when the input gear 21 is installed on the bracket body 10, it is suitable to be installed into the bracket body 10 through the top side opening 103. At this time, in the aforementioned step S12 of installing the first transmission assembly 20, the bracket body 10 can be placed with the top facing the assembly fixture 50 at the first positioning part 5111 of the first assembly part 51 of the fixture, so that the first transmission assembly 20 can enter the bracket body 10 through the top side opening 103. It is also convenient to use a locking screw from above to rotatably lock the input gear 21 to the base plate 12 of the bracket body 10.

[0051] Continue as Figures 5 to 7As illustrated, in step S21 of installing the slide rail assembly 30, the bottom of the bracket body 10 can be placed at the second positioning part 5112 of the first assembly part 51 of the assembly fixture 50 with the bottom facing the assembly fixture 50, so that the first transmission component 20 already assembled inside the bracket body 10 is in a region away from the second assembly part 52, so that when the slide rail assembly 30 is pushed into the bracket body 10, the slide rail assembly 30 located at the front end in the pushing direction can mesh well with the input gear 21 of the first transmission component 20.

[0052] It should be noted that the above embodiment only illustrates one type of bracket positioning structure 511, which includes two positioning parts to position the bracket body 10 in different postures and in different areas. This allows for higher and smoother assembly efficiency between the first transmission component 20 and the bracket body 10, and between the slide rail component 30 and the bracket body 10. It also allows the same assembly fixture 50 to well adapt to the assembly requirements of the two components at two stages.

[0053] In other embodiments, the bracket positioning structure 511 includes a first positioning part 5111 and a second positioning part 5112, which is also suitable for other assembly methods to improve assembly flexibility, efficiency and effectiveness.

[0054] In one embodiment, when the bracket positioning structure 511 includes a first positioning part 5111 and a second positioning part 5112, such as Figure 1 , Figure 2 , Figures 5 to 9 In the schematic diagram, in the first assembly part 51, the first positioning part 5111 and the second positioning part 5112 are distributed along the width direction of the assembly fixture 50, and the wheel positioning part 512 and the first positioning part 5111 are located in the same area of ​​the first assembly part 51. The first assembly part 51 and the second assembly part 52 are distributed along the length direction of the assembly fixture 50, and the extension direction of the guide structure 521 is consistent with the length direction of the assembly fixture 50.

[0055] For example, the width direction of the bracket body 10 of the telescopic bracket 200 is the x-direction (i.e., the left-right direction), and the length direction is the y-direction (i.e., the front-back direction). The first assembly part 51 is located in the front region of the fixture, the second assembly part 52 is located in the rear region of the fixture, the first positioning part 5111 is located in the left-side region of the front side of the fixture, and the second positioning part 5112 is located in the right-side region of the front side of the fixture. Wherein: When assembling the first transmission assembly 20 with the bracket body 10, the input gear 21 can be placed first at the wheel positioning part 512 on the left side of the front of the fixture. Then, the bracket body 10 is positioned at the first positioning part 5111 on the left side of the front. The input gear 21 is rotatably mounted to the wheel mounting part 13 of the bracket body 10 using screws or other connecting parts. When assembling the slide rail assembly 30 with the bracket body 10, the bracket body 10 is positioned at the second positioning part 5112 on the right side of the front. The slide rail assembly 30 is placed at the guide structure 521 of the second assembly part 52 on the rear side. The guide structure 521 extends from back to front. When the slide rail assembly 30 exerts a forward force, the slide rail assembly 30 slides along the guide structure 521 into the interior of the bracket body 10 until it is fully assembled.

[0056] The space occupied by the bracket body 10 when positioned in the first positioning part 5111 and the second positioning part 5112 can partially overlap, so as to reduce the requirement for the width of the fixture.

[0057] In this embodiment, by configuring the bracket positioning structure 511 to include two first positioning parts 5111 and second positioning parts 5112 arranged along the width direction of the bracket body 10, and the first assembly part 51 and second assembly part 52 arranged along the length direction of the bracket body 10, the first transmission assembly 20 and the slide rail assembly 30 can be installed into different areas in the width direction of the bracket body 10 in the first transmission assembly 20 installation step and the slide rail assembly 30 installation step, respectively. For example, it is convenient to install the input gear 21 into the first mounting cavity 101 of the bracket body 10 and the slide rail assembly 30 into the second mounting cavity 102 of the bracket body 10.

[0058] Optionally, the first transmission component 20 can be assembled with the bracket body 10 to form a first assembly module, then the second assembly module can be placed in the second positioning part 5112, and then the slide rail component 30 can be assembled with the bracket body 10. In this way, the transmission connection with the input gear 21 of the first transmission component 20 is completed during the assembly of the slide rail component 30.

[0059] It should be noted that the front, back, left, and right directions of the aforementioned fixture are only used to illustrate the relative positions of each component during the installation process and are not the only limitation in actual application scenarios.

[0060] In one embodiment, to reduce the difficulty of assembling the input gear 21 with the bracket body 10, the assembly fixture 50 is configured as follows. (Refer to...) Figure 1 , Figure 2 , Figure 5The wheel positioning part 512 includes a first positioning groove 5121 opened on the top of the first assembly part 51. The first positioning groove 5121 is used to position the outer circle of the input gear 21. That is, under the premise that the input gear 21 can be put into the first positioning groove 5121, the diameter of the input gear 21 is close to the diameter of the first positioning groove 5121.

[0061] When assembling the input gear 21 and the bracket body 10, first place the input gear 21 into the first positioning groove 5121 to restrict the horizontal position of the input gear 21. Then, place the bracket body 10 with its top facing the fixture and place the bracket body 10 at the first positioning part 5111 on the top of the first assembly part 51. During the process, allow the input gear 21 to enter the interior of the bracket body 10 through the top side opening 103. Then, using screws or other connecting parts (such as the second screw 41), the input gear 21 is rotatably mounted on the bottom plate 12 of the bracket body 10 from the bottom plate 12 of the bracket body 10.

[0062] Optionally, continue to refer to Figures 3 to 8 The input gear 21 in the telescopic bracket 200 is rotatably connected to the bracket body 10 in the following manner. The input gear 21 has a gear hole at its center. The telescopic bracket 200 includes a first screw 23 and a second screw 41, also referred to as the first and second screws. The first screw 23 is a hollow screw, and the first screw 23 has at least a threaded hole 231 on its shank. The second screw 41 has at least an external thread on its shank. The base plate 12 of the bracket body 10 is provided with a wheel mounting part 13, which is a through hole. The screw of the first screw 23 is inserted into the gear hole of the input gear 21. The screw head of the first screw 23 is located on the side of the input gear 21 away from the base plate 12 of the bracket body 10. The threaded hole 231 of the first screw 23 is aligned with the through hole of the base plate 12 of the bracket body 10. The screw of the second screw 41 passes through the through hole of the base plate 12 of the bracket body 10 and is screwed into the screw of the first screw 23. The screw head of the second screw 41 is located on the side of the base plate 12 of the bracket body 10 away from the input gear 21. The input gear 21 is rotatably mounted on the base plate 12 of the bracket body 10 by the threaded connection between the first screw 23 and the second screw 41.

[0063] In order to better assemble the input gear 21 with the bracket body 10 with the first screw 23 in place, refer to Figure 2 The bottom of the first positioning groove 5121 is provided with a second positioning groove 5122. The diameter of the second positioning groove 5122 is smaller than the diameter of the first positioning groove 5121. The second positioning groove 5122 is used to accommodate and position the screw head of the first screw 23 used to rotatably connect the input gear 21 to the bracket body 10.

[0064] In this embodiment, by limiting the outer circle of the input gear 21 through the first positioning groove 5121 and accommodating, avoiding, and positioning the screw head of the first screw 23 through the second positioning groove 5122, the relative positions of the input gear 21, the wheel mounting part 13 of the bracket body 10, and the second screw 41 (i.e., the rotating connector between the input gear 21 and the bracket body 10) can be fixed simultaneously. This ensures that the gear hole of the input gear 21, the threaded hole 231 of the first screw 23, and the through hole of the base plate 12 of the bracket body 10 are quickly and accurately aligned, reducing manual alignment and adjustment steps and improving assembly accuracy and efficiency.

[0065] In other embodiments, the second positioning slot 5122 may not be provided.

[0066] In one embodiment, reference is made to Figure 1 , Figure 5 , Figure 7 , Figure 9 When the bracket positioning structure 511 of the bracket body 10 includes a first positioning part 5111, the first positioning part 5111 is provided in the following manner: The first positioning part 5111 is a positioning boss. For example, the top of the first assembly part 51 has a main horizontal surface, and the first positioning part 5111 protrudes upward relative to the main horizontal surface. The wheel positioning part 512 is disposed on the top of the positioning boss. For example, the wheel positioning part 512 includes a first positioning groove 5121 formed on the top of the positioning boss.

[0067] The positioning boss is used to insert into the interior of the bracket body 10, for example, the positioning boss is used to insert into the first mounting cavity 101 of the bracket body 10. After the input gear 21 is positioned on the wheel positioning part 512 on the top of the positioning boss, the top of the bracket body 10 has a top side opening 103, the top side opening 103 of the bracket body 10 faces the fixture, the positioning boss enters into the interior of the bracket body 10 through the top side opening 103 so that the input gear 21 enters into the interior of the bracket body 10 to approach the bottom plate 12 of the bracket body 10. After the input gear 21 and the bracket body 10 are both positioned, the input gear 21 can be rotatably connected to the bracket body 10 using a rotating connector (such as the second screw 41 in the aforementioned embodiment).

[0068] In this embodiment, not only can the positioning boss position the bracket body 10 in the horizontal position of the fixture, but also the wheel positioning part 512 can be set on the top of the positioning boss so that when the bracket body 10 is positioned, the input gear 21 can be brought close to the bottom plate 12 of the bracket body 10, so that the second screw 41 can be fastened from the outside of the bottom plate 12 of the bracket body 10, thereby realizing the rotatable connection between the input gear 21 and the bracket body 10.

[0069] In other embodiments, the first positioning part 5111 may also be configured as a positioning groove provided on the horizontal surface of the first assembly part 51 of the bracket body 10. When the bracket body 10 is placed with its top facing down on the first assembly part 51, the shape of the positioning groove is adapted to at least a portion of the outer contour of the top of the bracket body 10 to position the bracket body 10. The wheel positioning part 512 is a separate protrusion structure to allow the input gear 21 to enter the interior of the bracket body 10 and approach the bottom plate 12 of the bracket body 10.

[0070] In one embodiment, reference is made to Figure 1 , Figure 5 , Figure 9 , Figure 11 When the bracket positioning structure 511 of the bracket body 10 includes a first positioning part 5111, the second positioning part 5112 is provided in the following manner: The bracket positioning structure 511 includes a second positioning part 5112, which is a positioning groove. The positioning groove is used to position the bracket body 10. That is, the positioning groove has a plane and groove sidewalls around the plane. The groove sidewalls of the positioning groove block at least the left and right sides of the bracket body 10 so that when the bracket body 10 is placed in the second positioning part 5112, the degree of freedom of the bracket body 10 in the width direction of the fixture is restricted, so that the slide rail assembly 30 located in the guide structure 521 can move along the length direction of the fixture under the action of pushing or pulling force, so as to slide from the end of the bracket body 10 into the interior of the bracket body 10.

[0071] For example, the bracket body 10 has a second mounting cavity 102. When the bracket body 10 is positioned in the second positioning part 5112 of the first assembly part 51 of the fixture, the guide structure 521 of the second assembly part 52 of the fixture can position the slide rail assembly 30 on the side corresponding to the second mounting cavity 102. By pushing the slide rail assembly 30, the slide rail assembly 30 can move linearly along the guide lower edge of the guide structure 521 to be inserted into the second mounting cavity 102 of the bracket body 10 from the end.

[0072] In this embodiment, the positioning groove restricts the freedom of the bracket body 10 in the width direction through the groove sidewall, ensuring the stability of the bracket body 10 position, so that the slide rail assembly 30 on the guide structure 521 can accurately align with the end opening 104 of the bracket body 10 along a straight line, avoiding jamming or damage to parts caused by bracket offset when the slide rail is pushed in, and improving the smoothness and accuracy of slide rail assembly.

[0073] In other embodiments, the second positioning part 5112 can also be configured as a positioning block group, that is, at least two spaced blocks (such as side blocks symmetrically arranged along the width direction of the fixture and end blocks arranged along the length direction) are provided on the top horizontal surface of the first assembly part 51. The side blocks restrict the displacement of the bracket body 10 in the width direction, and the end blocks limit its position in the length direction. Stable positioning of the bracket body 10 can be achieved without opening a complete groove. At the same time, the spacing of the block group can be adjusted according to the different sizes of bracket bodies 10 to adapt to the slide rail assembly requirements of more specifications of telescopic brackets 200.

[0074] In one embodiment, the guide structure 521 is configured as a guide groove formed on the top of the second assembly part 52. The guide groove extends along the length direction of the fixture (i.e., the pushing direction of the slide rail assembly 30), and its cavity size is adapted to the cross-sectional profile of the slide rail assembly 30, so that the slide rail assembly 30 can be stably limited and smoothly slid after being placed in.

[0075] The guide groove has a slot on the side near the first assembly part 51 (i.e., the end near the bracket body 10), which is the end opening 104 of the guide groove. When the bracket body 10 is positioned on the first assembly part 51 by the second positioning part 5112, the end opening 104 of the second mounting cavity 102 of the bracket body 10 for accommodating the slide rail assembly 30 is on the same straight line as the slot of the guide groove, forming an assembly channel from the guide groove to the interior of the bracket body 10.

[0076] An assembly example is provided. During assembly, the bracket body 10, which already has the input gear 21 installed, can be placed into the second positioning part 5112 of the first assembly part 51, so that the end opening 104 of the second mounting cavity 102 of the bracket body 10 faces the guide groove of the second assembly part 52. Then, the slide rail assembly 30 is placed into the guide groove of the second assembly part 52. Subsequently, the operator applies a pushing force to the slide rail assembly 30 along the length direction of the fixture (towards the first assembly part 51). The slide rail assembly 30 slides along the groove cavity of the guide groove, and after passing the guide groove and approaching the groove of the first assembly part 51, it directly enters the second mounting cavity 102 of the bracket body 10. During the process, the groove at the end of the guide groove plays a transitional role to avoid the slide rail assembly 30 getting stuck due to edge misalignment when entering the bracket body 10 from the guide groove. Finally, the slide rail assembly 30 is pushed until it meshes with the input gear 21 (first transmission assembly 20) in the bracket body 10. At this time, the slide rail assembly 30 is assembled in place to ensure smooth subsequent transmission.

[0077] In this embodiment, the guide groove is used to pre-position the slide rail assembly 30, and the groove opening is used to avoid or reduce the assembly gap between the guide groove and the bracket body 10, so as to avoid the slide rail assembly 30 from shifting or colliding during the pushing process, and the assembly process is smooth and efficient.

[0078] Furthermore, when the slide rail assembly 30 consists of multiple pre-assembled cooperating components, such as when the slide rail assembly 30 includes two telescopic frames 31 and a second transmission component 32 disposed between the two telescopic frames 31 to achieve transmission cooperation between them, and the two telescopic frames 31 can move synchronously in opposite directions, the entire slide rail assembly 30 can be directly placed into the guide groove, which facilitates the overall pushing of the slide rail assembly 30 without the need to configure multiple guide rails in the second assembly part 52 to guide individual components in the slide rail assembly 30 separately.

[0079] In other embodiments, the guide structure 521 may also be configured as a guide ridge extending along the length of the fixture.

[0080] In one embodiment, the second positioning portion 5112 in the first assembly portion 51 of the bracket is configured as a positioning groove as described in the above embodiment, and the guide structure 521 in the second assembly portion 52 of the bracket is configured as a guide groove as described in the above embodiment. The guide groove near the first assembly portion 51 and the positioning groove near the second assembly portion both have openings to allow communication between the positioning groove and the guide groove. To allow the slide rail assembly 30 to smoothly enter the interior of the bracket body 10 during assembly, the assembly fixture 50 is configured such that the bottom surface of the guide groove is higher than the bottom surface of the positioning groove.

[0081] When actually assembling the slide rail assembly 30 and the bracket body 10, the bracket body 10 is placed top-up in the positioning groove of the first assembly part 51, and the bottom plate 12 of the bracket body 10 will naturally abut against the bottom surface of the positioning groove. If the input gear 21 of the first transmission assembly 20 is pre-installed in the bracket body 10, the input gear 21 will be close to the positioning groove side along with the bottom plate 12, in a position that facilitates meshing with the slide rail assembly 30. At the same time, the slide rail assembly 30 is placed smoothly in the guide groove of the second assembly part 52. Since there is a height difference between the bottom surface of the guide groove and the bottom surface of the positioning groove, and this height difference is basically matched with the thickness of the bottom plate 12 of the bracket body 10, the bottom surface of the slide rail assembly 30 and the upper surface of the bottom plate 12 of the bracket body 10 can be kept basically horizontal. At this time, a thrust is applied to the slide rail assembly 30 toward the first assembly part 51. The slide rail assembly 30 slides along the guide groove and enters the positioning groove area through the connected slot. It can smoothly slide into the bracket body 10 in a horizontal posture, avoiding scraping or jamming between the slide rail assembly 30 and the inner wall of the bracket body 10 due to height misalignment.

[0082] In this embodiment, the height difference between the bottom surfaces of the two slots is designed to match the thickness of the base plate 12 of the bracket body 10, eliminating the height difference between the slide rail assembly 30 and the internal mounting surface of the bracket body 10. This ensures that the slide rail assembly 30 remains horizontal during the pushing process, avoiding assembly jamming or part wear caused by height deviation, and eliminating the need for manual adjustment of the height position of the slide rail assembly 30, thus reducing operational difficulty. Simultaneously, the interconnected slot design further enhances the continuity of the assembly channel, making the transition of the slide rail assembly 30 from the guide slot to the bracket body 10 smoother, effectively improving the efficiency and stability of slide rail assembly. Furthermore, when the input gear 21 pre-installed inside the bracket body 10 needs to mesh with the slide rail assembly 30, the horizontally pushed slide rail assembly 30 can more accurately engage with the input gear 21, ensuring the reliability of subsequent transmission.

[0083] In one embodiment, the second positioning portion 5112 in the first assembly portion 51 of the bracket is configured as a positioning groove as described in the above embodiment, and the guide structure 521 in the second assembly portion 52 of the bracket is configured as a guide groove as described in the above embodiment. When the slide rail assembly 30 includes two telescopic frames 31 and the two telescopic frames 31 are driven and engaged by the second transmission assembly 32, the assembly fixture 50 is configured as follows: The guide groove has an end groove surface facing the positioning groove on the side away from the positioning groove, and the end groove surface is connected to a spacer protrusion 522; the spacer protrusion 522 divides the guide groove into two guide spaces, which are used to accommodate two telescopic frames 31 in the slide rail assembly 30 respectively.

[0084] During actual assembly, the pre-assembled slide rail assembly 30 is first placed into the guide groove, and the two telescopic frames 31 are respectively placed into the two guide spaces separated by the spacer protrusion 522. Since each guide space only accommodates one telescopic frame 31, the two telescopic frames 31 will automatically maintain a preset interval distance without the need for manual adjustment of their lateral position. In addition, the second transmission assembly 32 between the two telescopic frames 31 can abut against the spacer protrusion 522. Subsequently, a thrust towards the positioning groove can be applied to the two telescopic frames 31 simultaneously, and the two telescopic frames 31 slide along their respective guide spaces, maintaining a parallel and stable spacing posture. After passing through the slot connecting the guide groove and the positioning groove, they simultaneously slide into the second mounting cavity 102 of the bracket body 10.

[0085] It should be further explained that the pre-assembled slide rail assembly 30 refers to two telescopic frames 31 connected by a second transmission assembly 32. The second transmission assembly 32 may include one or more transmission gears 321, with each side of the transmission gear 321 meshing with one of the two telescopic frames 31. This allows one of the telescopic frames 31 to mesh with the input gear 21 of the first transmission assembly 20 after being assembled into the bracket body 10. The input gear 21 then drives one telescopic frame 31 to move linearly, and the second transmission assembly 32 drives the other telescopic frame 31 to move linearly in the opposite direction via the transmission gear 321. The components of the pre-assembled slide rail assembly 30 are not immobile relative to each other. During the process of pushing the slide rail assembly 30 into the bracket body 10, a thrust is applied synchronously to the two telescopic frames 31 to ensure the stability of the entire slide rail assembly 30.

[0086] In this embodiment, the spacer protrusion 522 forms two guide spaces in the guide groove, facilitating proper lateral spacing and end alignment of the two telescopic frames 31 during the initial positioning of the slide rail assembly 30. Furthermore, the spacer protrusion 522 also provides support and a positioning reference for the second transmission assembly 32. When the two telescopic frames 31 slide synchronously into the second mounting cavity 102 of the bracket body 10, the spacer protrusion 522 ensures the lateral spacing, end alignment, and positional accuracy of the second transmission assembly 32 of the two telescopic frames 31 in the initial stage. This allows one of the telescopic frames 31 to quickly and precisely mesh with the input gear 21 of the first transmission assembly 20 within the bracket body 10 without subsequent adjustments. The second transmission assembly 32 can also directly maintain its preset transmission posture. When the input gear 21 drives one of the telescopic frames 31 in linear motion, it can stably drive the other telescopic frame 31 in reverse linear motion via its own transmission gear 321, effectively avoiding problems such as transmission jamming, gear wear, or asynchronous movement caused by assembly deviations.

[0087] The telescopic bracket 200 assembly fixture 50 provided in this application is used to assist in the assembly of the telescopic bracket 200, thereby improving the assembly efficiency between its components and modules. The following describes a telescopic bracket 200 that can be assembled with the assistance of the assembly fixture 50 of this application.

[0088] The telescopic bracket 200 core includes a bracket body 10, a first transmission component 20, and a slide rail assembly 30. The first transmission component 20 contains two input gears 21 and a synchronous belt 22. Each input gear 21 has a coaxially connected main wheel 211 and a secondary wheel 212 (the secondary wheel 212 has a smaller diameter than the main wheel 211), and the main wheels 211 of the two input gears have different diameters. The synchronous belt 22 is fitted between the two secondary wheels 212. During operation, the input gear 21 with the smaller diameter main wheel 211 engages with the drive component 400 (a slider that moves with the telescopic bracket 200 and slides relative to the bracket body 10). When the telescopic bracket 200 is raised or lowered as a whole, the drive component 400 slides along the length of the bracket body 10, thereby rotating the smaller diameter input gear 21. The synchronous belt 22 then drives the larger diameter input gear 21 to rotate synchronously, amplifying the torque and providing a more stable and reliable drive for the subsequent movement of the slide rail assembly 30.

[0089] The slide rail assembly 30 includes two telescopic frames 31 and a second transmission assembly 32 connecting them. The second transmission assembly 32 contains one or more transmission gears 321, which mesh between the two telescopic frames 31. The larger-diameter input gear 21 in the first transmission assembly 20 meshes with the rack of the first telescopic frame 31. When the input gear 21 rotates, it drives the first telescopic frame 31 to move linearly. The first telescopic frame 31, in turn, drives the second telescopic frame 31 to move linearly in the opposite direction via the transmission gear 321 of the second transmission assembly 32, thus achieving synchronous reverse adjustment of the two telescopic frames 31.

[0090] In the clothes drying rack scenario, the entire drying rack can be raised and lowered by winding or unwinding the traction component (such as a steel wire rope) within the connecting assembly 300. During the raising and lowering process, the drive component 400, hinged at the bottom of the scissor frame within the connecting assembly 300, slides back and forth along the bracket body 10, thereby driving the two telescopic frames 31 of the slide rail assembly 30 to simultaneously extend outward or retract inward into the bracket body 10 via the first transmission component 20. If both telescopic frames 31 are connected to drying rods 500 at their outer ends, the spacing between the drying rods 500 can be flexibly adjusted to adapt to different drying needs.
