Detailed Description
For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
As shown in fig. 1 to 5, a rotatable anti-drop handle of the present invention comprises a crown 10, a cotter 20 and a handle bar 30, one end of the crown 10 is provided with a counter bore 11, the other end of the crown 10 is used for connecting external mechanical equipment, the handle 30 comprises a handle head 31, a first step 32 and a second step 33 which are connected in sequence, the cotter 20 has a C-shaped cross-section, the cotter 20 is made of stainless steel, the cross-section of the cotter pin 20, the cross-section of the first step 32 and the cross-section of the second step 33 are all circular configurations, the cotter pin 20 is held in the first step 32, the inner diameter of the cotter pin 20 is smaller than the sectional diameter of the shank head 31 and the sectional diameter of the second step 33, thereby trapping the cotter pin 20 in the first step 32 between the shank head 31 and the second step 33; the inside diameter of the cotter 20 is greater than the cross-sectional diameter of the first step 32 and the height of the cotter 20 is less than the length of the first step 32 to allow for relative rotation between the cotter 20 and the first step 32 to ensure that the shank 30 is loosely retained in the cotter 20.
The outer diameter of the split pin 20 is larger than the section diameter of the handle rod head 31 and the section diameter of the second stepped section 33, the split pin 20 is clamped in the counter bore 11, meanwhile, the outer diameter of the split pin 20 is larger than the section diameter of the counter bore 11 of the handle head 10, specifically, the split pin 20 is in interference fit with the counter bore 11, so that the split pin 20 is tightly clamped in the counter bore 11.
In one embodiment, the depth of the counter bore 11 is greater than the total length of the shank head 31 and the first step 32, so that the cotter pin 20 can be stably clamped in the counter bore 11, and the shank head 31 is prevented from abutting against the bottom end of the counter bore 11 to affect the rotation effect of the shank 30.
In one embodiment, the handle 10 further has a receiving groove 12 formed at an outer side portion of the countersunk hole 11, the countersunk hole 11 is communicated with the receiving groove 12, the handle 30 is further provided with a third step 34, the third step 34 extends from a second step 33, a cross section of the third step 34 is a circular structure, a cross-sectional diameter of the third step 34 is larger than a cross-sectional diameter of the countersunk hole 11, a joint of the third step 34 and the second step 33 is received in the receiving groove 12, and a cross-sectional diameter of the third step 34 is smaller than a cross-sectional diameter of the receiving groove 12, so as to prevent a sidewall of the receiving groove 12 from contacting with an outer surface of the third step 34 when the handle 30 rotates, thereby causing unnecessary resistance to the handle 30; the end face of the third step 34 is in contact with the end face of the counter bore 11, the end face of the counter bore 11 abuts against the end face of the third step 34, the handle rod head 31 and the first step 32 of the handle rod 30 are prevented from penetrating into the bottom end of the counter bore 11, the handle rod 30 is more effectively limited, and the problem that the handle rod head 31 abuts against the bottom end of the counter bore 11 after being assembled into the counter bore 11 is solved.
The utility model discloses during the specific equipment, hammer split pin 20 into the first step 32 of handle pole 30 through hammer exogenic action, because the internal diameter of split pin 20 is less than the cross-sectional diameter of handle pole head 31 and the cross-sectional diameter of second step 33, the length of first step 32 is slightly bigger than the length of split pin 20, so hammer split pin 20 into first step 32 after, split pin 20 can be restricted on first step 32 after contracting, make split pin 20 can have slight upper and lower displacement and can not drop from handle pole 30, simultaneously, because the internal diameter of split pin 20 is slightly bigger than the cross-sectional diameter of first step 32, so can relative rotation between split pin 20 and the handle pole 30; then the handle bar 30 and the split pin 20 are simultaneously hammered into the countersunk hole 11 of the crown 10 until the end surface of the third step section 34 of the handle bar 30 contacts with the end surface of the countersunk hole 11 of the crown 10, and as the outer diameter of the split pin 20 is larger than the cross-sectional diameter of the countersunk hole 11 of the crown 10, namely the split pin 20 and the countersunk hole 11 of the crown 10 are in interference fit, the split pin 20 cannot fall off from the inside of the countersunk hole 11 of the crown 10 after being installed, and the split pin 20 and the handle bar 30 cannot fall off, so that the handle bar 10, the split pin 20 and the handle bar 30 cannot fall off, and the effect that the handle bar 30 rotates in the countersunk hole 11 of the crown 10 is also realized.
To sum up, the utility model relates to a rotatable anti-drop handle is through seting up counter bore 11 on crown 10, the cooperation sets up crown head 31 on crown 30, first step 32 and second step 33, hold split pin 20 card in first step 32, rethread exogenic action is with split pin 20 and 11 interference fit of counter bore, thereby make split pin 20 and crown 30's crown head 31 and first step 32 holding simultaneously in counter bore 11, because split pin 20 is interference fit with crown 10's counter bore 11, so install back split pin 20 and can not follow the inside of 10 counter bore 11 of crown 10 and drop, and split pin 20 can not drop with crown 30 again, so crown 10, can not drop between split pin 20 and the crown 30 three, the effect of crown 30 internal rotation in 10's counter bore 11 has also been realized to the while.
The above-described embodiments are merely illustrative of several embodiments of the present invention, which are described in detail and specific, but not intended to be construed as limiting the scope of the present invention.
