Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel handrail assembly, in particular to a clamping tool for assembling stainless steel handrails. Background Art

[0002] Stainless steel handrails are widely used in indoor and outdoor buildings. Stainless steel handrails are wear-resistant, corrosion-resistant, easy to clean and maintain, and also have high safety. Before installing the stainless steel handrail, multiple sections of stainless steel pipes need to be assembled first, and assembled by welding or mortise and tenon joints. The existing patent (Announcement No.: CN212265002U) discloses a welding tool for stainless steel door handrails on subway vehicles. The utility model sets a gear box to achieve a fixed angle of 90 degrees or 120 degrees for the handrail to ensure consistent concentricity. It also cooperates with a connecting sleeve to be suitable for a variety of handrail sizes, which improves the flexibility of use. However, in actual applications, many stainless steel handrails have curved parts, and two sections of stainless steel straight pipes need to be connected to the two ends of the curved pipe respectively. It is difficult to clamp and connect such handrails with curved parts using the above utility model, which is limited in use and affects practical applications. To this end, we propose a clamping tool for assembling stainless steel handrails. Utility Model Content

[0024] Further, the clamping assembly 2 includes an assembly seat 22 respectively fixed to the fixed block 31 and the slide 34, and a V-shaped clamp block 21 is detachably connected to the assembly seat 22. The V-shaped clamp block 21 is used to clamp the stainless steel handrail pipe fitting, which has the effect of automatic alignment and is convenient for precise docking. By removing the V-shaped clamp block 21, it is convenient to replace the V-shaped clamp block 21 with different angles to adapt to the radius of the stainless steel handrail pipe fitting;

[0025] Further, the bottom of the V-shaped clamp 21 is threadedly connected with a screw rod 23, and a screw hole matching the screw rod 23 is provided at the bottom of the V-shaped clamp 21. The screw rod 23 is an iron screw rod. A magnetic suction sleeve 25 matching the screw rod 23 is fixedly embedded at the top of the assembly seat 22.

[0026] The base 1 is connected to the swing arm 4 via the rotating shaft 7. The rotating shaft 7 is fixed to the swing arm 4 and is movably connected to the base 1. Another clamping mechanism is arranged on the swing arm 4. A clamping assembly 2 13 having the same structure as the clamping assembly 1 2 is slidably arranged at one end of the swing arm 4 close to the rotating shaft 7.

[0031] Further, a sliding seat 14 is fixed at the bottom of the clamping component 13, and a slide rail 15 matching the sliding seat 14 is fixed on the swing arm 4. By moving the sliding seat 14, the clamping component 13 is moved to match the length of the bent pipe so that the bent pipe and the straight pipe can be docked. A limiting mechanism 16 is provided on the clamping component 13, and the limiting mechanism 16 includes an assembly plate 161 fixed to the clamping component 13, and a friction frame 162 abutting against the swing arm 4 is provided below the assembly plate 161. The bottom of the friction frame 162 is provided with a friction frame for increasing The friction convex block, the assembly plate 161 is threadedly connected with a screw rod 163 movably connected to the friction frame 162, and a limit rod 164 movably inserted on the assembly plate 161 is fixed on the top of the friction frame 162; by rotating the screw rod 163, the friction frame 162 is guided by the limit rod 164 to perform a linear motion in the vertical direction. When the bottom of the friction frame 162 is pressed against the swing arm 4, the movement trend of the sliding seat 14 is suppressed, and the clamping component 13 is prevented from driving the bent pipe to shift, thereby improving the clamping stability;

[0032] Specifically, by setting a rotating shaft 7, a swing arm 4, two sets of clamping mechanisms and a clamping assembly 13, the clamping mechanism is used to respectively clamp the straight pipes that need to be connected at both ends of the bent pipe, and then the clamping assembly 13 is used to clamp the bent pipe.
