Abstract
Description
Technical Field
[0001] This utility model belongs to the field of industrial equipment technology and relates to a horizontal tube structure for fixing a front support. Background Technology
[0002] The workbench is a professional operating platform designed for various work needs. Its core function is to provide users with a safe and stable working space through a steel structure or reinforced material tabletop (with a load-bearing capacity of 500kg to 2 tons) and an optimized support system. The standard tabletop size is 1200×600mm to 2400×1200mm. According to the application scenario, it can be divided into three professional configurations: industrial manufacturing type with vise mounting position and pneumatic interface (50mm thickened tabletop); laboratory type with acid and alkali resistant ceramic tabletop and integrated safety device; and electronic repair type with anti-static system and LED lighting. Through the synergistic effect of four-point support structure, transverse reinforcing beam and self-locking anti-slip pads, it can ensure that the change in the distance between the support legs under dynamic load is <0.5mm. A typical application is that the tabletop levelness error is <0.3 when the load is 1.2 tons in an automotive repair shop. The workbench also features a modular design with height adjustment (650-1200mm) and tool racks, enabling storage space to be expanded by 30% to 200%, fully meeting the needs of manufacturing, testing, and maintenance scenarios for stability, functionality, and ergonomics.
[0003] In actual use of the workbench, when large or heavy items are placed on it, the support legs often bear uneven load distribution. Especially when the center of gravity of the item shifts or dynamic operations are performed, such as hammering or machining, the traditional support structure is prone to inward deformation due to unidirectional force. This deformation usually manifests as the two support legs gradually moving towards the central axis as the weight of the item increases, causing the workbench surface to tilt. This not only affects the accuracy of operation but may also cause the safety hazard of the item slipping. Utility Model Content

[0025] Example 1
[0026] like Figure 1 - Figure 4 As shown, the front bracket fixing horizontal tube structure includes two bracket bodies 101; each of the two bracket bodies 101 is fixedly connected to a support frame 102 at one end close to each other; multiple sets of fixing screws 103 are provided on the inner side of each bracket body 101; a serrated column 104 is fixedly connected to the upper end of each support frame 102; a limiting sleeve 105 is provided between the two bracket bodies 101; two sets of threaded rods 106 are threadedly connected to the inner side of the limiting sleeve 105; the threaded rods 106 are close to the bracket body. One end of 101 is fixedly connected to a limiting post a107; a fixed shaft a108 is fixedly connected to the middle of the outer side of the limiting post a107; a limiting ring a109 is sleeved on the outer side of the fixed shaft a108; the limiting ring a109 is rotatably connected to the fixed shaft a108; a fixing block 110 is fixedly connected to the end of the limiting ring a109 away from the threaded rod 106; a sawtooth through groove 111 is opened on the inner side of the fixing block 110; the sawtooth through groove 111 is slidably engaged with the sawtooth post 104.
[0027] During operation, firstly, use fixing screws 103 to install the two bracket bodies 101 onto the support legs of the workbench. After the two are fixed, remove the limiting cylinder 105. Then, rotate the threaded rod 106 inside the limiting cylinder 105. Utilize the threaded engagement of the two to make the threaded rod 106 extend outward from inside the limiting cylinder 105. After adjusting the distance between the limiting cylinder 105 and the two sets of threaded rods 106 to a suitable position, fit the two sawtooth through grooves 111 onto the outside of the sawtooth column 104 to lock the support legs, preventing the distance from widening due to force and ensuring the stability of the workbench.
[0028] Example 2
[0029] like Figure 1 - Figure 6 As shown, each of the two threaded rods 106 is fixedly connected to a limiting post b201 at one end close to the other; a fixed shaft b202 is fixedly connected to the outer side of the limiting post b201; a limiting ring b203 is sleeved on the outer side of the fixed shaft b202; the limiting ring b203 is rotatably connected to the fixed shaft b202; the limiting ring b203 is located inside the limiting cylinder 105 and is slidably connected to the limiting cylinder 105.
[0030] The outer side of the limiting ring b203 is symmetrically fixedly connected with the fixing plate a301 and the fixing plate b303; the inner side of the limiting cylinder 105 is provided with multiple sets of guide grooves 302.
[0031] The end corner of the fixed plate a301 is symmetrically fixedly connected with a sleeve 401; two sets of semi-rings 403 are symmetrically arranged on the outer side of the limiting cylinder 105; a rotating rod 402 is fixedly connected to one end of the semi-ring 403 near the fixed plate a301; the two ends of the rotating rod 402 are respectively rotatably connected to the two sets of sleeves 401.
[0032] The limiting cylinder 105 has a limiting groove 501 on its outer side; the semi-ring 403 is fixedly connected to a limiting block 502 on its inner side; the limiting block 502 is engaged with the threaded rod 106.
[0033] A locking screw 601 is provided on the inner side of the fixing plate b303; the locking screw 601 is threadedly connected to the semi-ring 403.
[0034] During operation, when the threaded rod 106 moves, it drives the limiting ring b203 to move inside the limiting cylinder 105 via the limiting post b201 and the fixed shaft b202. Simultaneously, the limiting ring b203 drives the fixed plate a301 and fixed plate b303 to slide inside the guide groove 302. After the threaded rod 106 and the limiting cylinder 105 are adjusted, the semi-ring 403 rotates around the center of the sleeve 401, causing the semi-ring 403 to engage with the limiting block 502 and the limiting groove 501. After engagement, rotating the locking screw 601 threads the locking screw 601 and the semi-ring 403 together.
[0035] The limiting block 502 and the limiting groove 501 are interlocked, thereby effectively fixing the angle of the limiting cylinder 105 and the threaded rod 106 after adjustment.
