Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a diagonal bracing mechanism with adjustable length. Background Technology

[0002] In scenarios such as temporary support in building construction, equipment installation and fixing, and auxiliary support for furniture, the diagonal bracing mechanism is a key component for achieving structural stability, and its length adaptability directly affects the support accuracy and stability.

[0003] In existing technologies, most products only use a single pin-type coarse adjustment structure, achieving length adjustment through pre-reserved fixed positions. Although the adjustment speed is relatively fast, the fixed position spacing cannot accurately adapt to non-standard spacing, resulting in a loose fit between the support platform and the wall, uneven force distribution, and easy loosening. Other products rely solely on a threaded fine adjustment structure, which can achieve high-precision adjustment, but the adjustment range is limited. When the spacing difference is large, it requires a long period of rotation for adjustment, resulting in extremely low operational efficiency and failing to meet the needs of rapid installation. Therefore, we have designed a length-adjustable diagonal brace mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable length diagonal brace mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-length inclined support arm mechanism, comprising: The diagonal bracing tube includes a round steel pipe and a telescopic pipe, wherein the telescopic pipe is inserted into the round steel pipe; The mounting base is hinged to the bottom of the round steel pipe and fixed to the ground with anchor bolts to secure the diagonal bracing pipe. The support platform is set above the telescopic pipe to fit against the wall and, together with the diagonal brace and the mounting base, provides support. The limiting block includes an insertion part and a fixing part. The insertion part is inserted into the inclined support tube, and the fixing part is disposed in the insertion part. The limiting block is used to fix the round steel tube and the telescopic tube after the initial length adjustment. The threaded rod includes a threaded end and a drive end. The threaded end is threadedly connected to the telescopic tube. The outer wall of the drive end is provided with a connector that connects to the support platform. After initial adjustment, the overall length of the diagonal brace tube can be finely adjusted by rotating the threaded end through the drive end.

[0006] Preferably, the round steel pipe has multiple insertion interfaces on its surface, the telescopic pipe has a slot on its surface, and the limiting block is inserted into the slot through the insertion interfaces to fix the adjusted round steel pipe and telescopic pipe.

[0007] Preferably, the plug-in part includes a plug-in block, one end of which is fixedly connected to a knob, and the outer wall of the plug-in block has multiple through holes, with the fixing part disposed in the through holes.

[0008] Preferably, the fixing part includes a spring, and the two ends of the spring are fixedly connected to the locking blocks, which are slidably connected to the inner wall of the through hole.

[0009] Preferably, the end of the card block near the inner wall of the slot is set as a hemisphere, and the inner wall of the slot has multiple hemisphere grooves. The hemisphere end of the card block is inserted into the hemisphere groove by the elastic force of the spring.

[0010] Preferably, the threaded end is threadedly connected to the inner wall of the telescopic tube, and a support rod is fixedly connected to the top of the threaded end, with the top of the support rod fixedly connected to the drive end.

[0011] Preferably, the drive end includes a top plate, and two rotating handles arranged in a circumferential array are fixedly connected below the top plate, with the telescopic tube located between the two rotating handles.

[0012] Preferably, the top plate is rotatably connected to the inner wall of the connector, and a plurality of auxiliary blocks arranged in a circumferential array are provided between the connector and the drive end. The auxiliary blocks are used to assist the top plate in rotating independently relative to the connector, and the top of the connector is fixedly connected to the support platform.

[0013] The technical effects and advantages of this utility model are as follows: This invention achieves a dual improvement in the efficiency and precision of diagonal brace length adjustment through a coordinated coarse and fine adjustment structure. In the coarse adjustment stage, the insertion and connection of the telescopic tube and the round steel tube, combined with the multi-position insertion interface design of the limiting block, allows for quick adaptation to different spacing ranges. Furthermore, the spring-driven hemispherical locking block engages with the groove surface, achieving rapid positioning and stable locking after coarse adjustment, making operation convenient and efficient. In the fine adjustment stage, rotating the handle drives the threaded rod to rotate, utilizing threaded transmission to achieve high-precision adjustment, accurately compensating for gaps in the coarse adjustment positions, ensuring a tight fit between the support platform and the wall, and preventing uneven force distribution. The combined effect of these two methods solves the problems of poor adaptability and loose fit associated with coarse adjustment alone, while overcoming the shortcomings of narrow adjustment range and cumbersome operation associated with fine adjustment alone, significantly improving the installation efficiency, adaptability, and support stability of the diagonal brace mechanism.
