Description

Welding workbench bracket fixing bolt improved structure

The present invention provides a technical field of a welding workbench, in particular, a technically improved structure for fixing a bolt of a welding table bracket, wherein a fixing hole is provided at the end of the outer sleeve of the bracket fixing bolt, and an arc convex fixing member is combined with the arc convex The arc convex surface of the fixing member is higher than the tapered hole, and the steel ball does not fall to form a fault, thereby ensuring that the bracket fixing bolt can be kept in a normal use state.

According to the ninth figure, it is a conventional bracket fixing bolt, which comprises an outer sleeve 11 which is drilled by a drill bit to cut a non-penetrating concave hole 111, and then The inner thread 112 is formed on the upper portion of the concave hole 111. The concave hole 111 is provided with four tapered holes 113 in the circumferential direction. The position of the tapered hole 113 is assembled into the steel ball 12, and then the middle portion of the bolt rod 13 The thread 131 is locked to the inner thread 112, and the front taper head 132 of the bolt rod 13 pushes against all the steel balls 12.

However, in the conventional bracket fixing bolt, the bolt rod 13 is rotated upward and retracted from the outer sleeve 11. When the bolt rod 13 is rotated slightly and cannot contact the steel ball 12, the natural gravity of the steel ball 12 will fall to a low position. When it is a steel ball When the 12 is dropped into the concave hole 111, the deviation position has exceeded the taper of the taper head 132 of the bolt rod 13 to push the range, the bolt rod 13 will lose its effect, and the bracket fixing bolt is in a fault state at this time, and it is necessary to wait until all the steel balls 12 are returned. The corresponding tapered holes 113 and the bracket fixing bolts can work again. Therefore, the conventional bracket fixing bolts still have inconvenience and defects and need to be improved.
