Description

Technical Field

[0001] This utility model relates to the field of support and hanger technology, specifically a constant force spring support and hanger that is easy to assemble and disassemble. Background Technology

[0002] Existing constant force spring supports rely primarily on internal springs for adjustment during use. After prolonged use, these springs are prone to damage and fail to meet operational requirements, necessitating replacement. For example, Chinese patent publication CN222297184U, dated January 23, 2025, discloses a utility model patent for an "easy-to-maintain constant force spring support," which includes a mounting plate. A hanger is fixedly connected to the lower end of the mounting plate, and a guide rod is fixedly connected to the top of the hanger's interior. A sliding plate is slidably connected to the circumferential surface of the guide rod. The lower end of the sliding plate is detachably connected to a first fixing plate. Multiple threaded shafts are fixedly connected to the upper end of the first fixing plate, and nuts are threaded onto the circumferential surfaces of each threaded shaft. A fixed support rod is fixedly connected to the lower end of the sliding plate. A fixing cylinder is detachably connected to the circumferential surface of the fixed support rod via a third bolt. An upper mounting ring is fixedly connected to the lower end of the fixing cylinder. A lower mounting ring is detachably connected to the lower end of the upper mounting ring via a first bolt. A second annular connecting plate is fixedly connected to the circumferential surface of the hanger. The lower end of the second annular connecting plate is detachably connected to the first annular connecting plate via a second bolt. This solution allows the entire constant force spring hanger to be disassembled into multiple parts, each of which can be individually disassembled and replaced, enabling inspection and maintenance of the internal components. However, this solution uses multiple bolts, requiring each bolt to be loosened and removed individually when replacing the spring, and then tightened again during installation. Because the bolts and nuts are small, they are easily missed or lost during installation. Utility Model Content

The top of the receiving groove 157 is provided with a locking groove 158 that allows the locking sleeve 150 to be inserted. By rotating the threaded connecting rod 155 to engage it in the receiving groove 157, and then rotating the drive ring 156 to insert the locking sleeve 150 into the locking groove 158, the upper pipe clamp 151 and the lower pipe clamp 152 are locked together.

[0033] Furthermore, the top of the upper pipe clamp 151 is provided with a mounting post 159, and the top end face of the mounting post 159 is provided with an internal thread groove that is screwed to the threaded end 122.

[0034] Furthermore, a guide block 126 is provided on the inner side wall of the top of the first snap-fit ​​groove 124, and a guide groove 127 is provided on the top end face of the sliding plate 12 to allow the guide block 126 to move. Through the setting of the guide groove 127 and the guide block 126, the fixed seat 123 always maintains the connection relationship with the sliding plate 12.

[0035] Furthermore, the inner wall of the first snap-fit ​​groove 124 is provided with a first magnet 128, and the outer wall of the sliding plate 12 is provided with a second magnet 129 that corresponds to the first magnet 128 and is magnetically attracted to it. Through the arrangement of the first magnet 128 and the second magnet 129, the fixing seat 123 and the sliding plate 12 are initially fixedly connected.

[0036] Furthermore, the upper buffer plate 131 is provided with a positioning rod 130 on its top end face, and the sliding plate 12 is provided with a positioning groove 120 for the positioning rod 130 to be inserted into. The positioning groove 120 and the positioning rod 130 are provided to position the upper buffer plate 131 and the sliding plate 12 during installation.

[0037] Furthermore, the inner wall of the housing 11 is provided with a displacement groove 118 that allows the fixed seat 123 to move up and down. The fixed seat 123 and the displacement groove 118 are configured to not only guide the sliding plate 12 to move up and down, but also to further limit and fix the fixed seat 123 and the sliding plate 12, so that the upper buffer plate 131 and the sliding plate 12 are firmly connected together. The bottom of the housing 11 is provided with a through groove 110 that allows the support rod 121 to slide.

[0038] The working principle of this utility model:

[0039] When it is necessary to replace spring 13, first rotate clamping assembly 15 to remove clamping assembly 15 from support rod 121. Then rotate drive plate 115 to completely disengage threaded rod 116 from first fastening hole 117 and second fastening hole 140. Next, rotate cover 14 to disengage first mounting plate 111 from mounting groove 142 of cover 14 and remove cover 14 upwards. Then push support rod 121 upwards to remove sliding plate 12 and spring 13 from the top opening of housing 11. Then pull fixed seat 123 outwards to disengage upper buffer plate 131 from second snap groove 125 of fixed seat 123, thereby disconnecting upper buffer plate 131 from sliding plate 12. Finally, remove spring 13 from support rod 121 and replace with a new spring 13.
