Improved flotation tool construction

Abstract

The invention provides an improved buoyancy tool structure which comprises a body. The body comprises a first combination and a second combination, wherein, an air drain and a cladding slot are arranged inside at least one of the first combination and the second combination; the body leads the first combination and the second combination to be welded and combined with ultrasonic welding mode; a driving piece is arranged in the cladding slot; after the first combination and the second combination are welded and combined, the air drain becomes an air chamber in sealed state and is filled with proper air; the first combination forms a concave section on the external end surface of the cladding slot; the second combination forms a convex section on the external end surface of the cladding slot; and the concave section and the convex section are in paired welding for strengthening the tightness of the body molding. By adopting the structure, the body has floating effect, and the inside of the body achieve completely closed and sealed without water leakage and seepage, thereby improving the convenience of operation.

Description

technical field [0001] The present invention relates to an improved buoyancy tool structure. Background technique [0002] General tools, their operating sites and objects are mostly built in factories on land, or machinery manufactured in factories. In order to ensure a strong and durable structure, tools are mostly made and forged from high-strength metals. The structure can withstand the stress generated in the operation, as well as the collision and knocking in use; [0003] However, if the operation place is changed from land to water, tools with solid metal structures become unfavorable, or even counterproductive, such as instrument maintenance and mechanical repair in rivers, rivers, oceans, or fish farms, ponds, and sluices , or ship repair, troubleshooting, emergency rescue, etc., the structure originally made of fine steel, because of its thick and heavy quality, coupled with the pressure in the water, makes it extremely difficult to use and operate, or it often s...

Problems solved by technology

[0005] However, although this kind of structure can make the tool float on the water, because the handle body keeps the air chamber closed by the screw cap to the screw hole, even if the screw cap is screwed tightly, the water can still pass through the tiny thread gap. If the water pressure is stronger, it will be more so. Moreover, after the screw cap and the screw hole are unscrewed and screwed in many times, the threads of each other will lose each other, so the gap between the threads will become larger and larger. Water infiltrates at will, and the sealing effect of the air chamber disappears, so that the body completely loses the floating effect
