Abstract
The utility model discloses a two have reinforcing apparatus to wearing screw rod, including the screw body of rod, recess, upper end stopper, lower extreme stopper, spring, spacing arch, stopper screw thread and screw pole screw thread, screw body of rod both ends all are equipped with the recess, upper end stopper and lower extreme stopper are fixed respectively in the recess at screw body of rod both ends, the spring is fixed in upper end stopper and lower extreme stopper bottom, all be equipped with spacing arch and stopper screw thread on upper end stopper and the lower extreme stopper, be equipped with screw pole screw thread on the screw body of rod, the utility model discloses it has seted up the recess at the upper and lower both ends of the screw body of rod to lead to to installed upper end stopper, lower extreme stopper and spring structure respectively in the recess at screw body of rod both ends, therefore people are using when wearing the screw rod, as long as screw up two nuts, these two nuts will be blocked by upper end stopper and lower extreme stopper naturally, even if how the machine vibrates the nut perhaps slippage of also can not loosening again like this.
Description
[technical field]
The utility model relates to the technical field of fastening piece, particularly a kind of two with reinforcing device. to the technical field of wearing screw rod.
[background technique]
Screw rod is that outer surface is cut spiral fluted cylinder or cut the circular cone of Conical Spiral Groove, and screw rod has different heads, has outer-hexagonal screw rod, large flat screw rod, hexagon socket head cap screw etc.; Traditional does not generally have limiting locking device structure to wearing on screw rod, because a lot of screw rod is all use on machine, after starting the machine, a little vibration can be there is in machine, when using nut of a specified duration to come loose even to depart from screw rod, cause important impact will to like this normal operation of machine to wearing screw rod.
[summary of the invention]
The purpose of this utility model is exactly to solve the problems of the prior art, propose a kind of two with reinforcing device. to wearing screw rod, the utility model leads to has offered groove at the two ends up and down of screw rod body, and in the groove at screw rod body two ends, upper end limiting stopper, lower end limiting stopper and spring structure have been installed respectively, therefore people use to when wearing screw rod, as long as two nuts are tightened, these two nuts will be blocked by upper end limiting stopper and lower end limiting stopper naturally, even if how machine vibrates nut again and also can not come loose or slippage like this.
For achieving the above object, the utility model proposes a kind of two with reinforcing device. to wearing screw rod, comprise screw rod body, groove, upper end limiting stopper, lower end limiting stopper, spring, spacing preiection, limiting stopper screw thread and lead screw screw thread, described screw rod body two ends are equipped with groove, described upper end limiting stopper and lower end limiting stopper are separately fixed in the groove at screw rod body two ends, described spring is fixed on bottom upper end limiting stopper and lower end limiting stopper, described upper end limiting stopper and lower end limiting stopper are equipped with spacing preiection and limiting stopper screw thread, described screw rod body is provided with lead screw screw thread.
As preferably, described limiting stopper screw thread and lead screw screw thread communicate after being spliced into one, and described upper end limiting stopper is identical with the cross section radian of screw rod body with the edge radian of lower end limiting stopper, and are sliceablely integrated.
As preferably, the distance between described upper end limiting stopper and lower end limiting stopper equals the distance between two nuts after locking.
The beneficial effects of the utility model: the utility model leads to has offered groove at the two ends up and down of screw rod body, and in the groove at screw rod body two ends, upper end limiting stopper, lower end limiting stopper and spring structure have been installed respectively, therefore people use to when wearing screw rod, as long as two nuts are tightened, these two nuts will be blocked by upper end limiting stopper and lower end limiting stopper naturally, even if how machine vibrates nut again and also can not come loose or slippage like this.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 be a kind of two of the utility model with reinforcing device. to the plan view wearing screw rod.
Fig. 2 is A-A sectional view.
In figure: 1-screw rod body, 2-groove, 3-upper end limiting stopper, 4-lower end limiting stopper, 5-spring, 6-spacing preiection, 7-limiting stopper screw thread, 8-lead screw screw thread.
[embodiment]
Consult Fig. 1 and Fig. 2, the utility model be a kind of two with reinforcing device. to wearing screw rod, comprise screw rod body 1, groove 2, upper end limiting stopper 3, lower end limiting stopper 4, spring 5, spacing preiection 6, limiting stopper screw thread 7 and lead screw screw thread 8, described screw rod body 1 two ends are equipped with groove 2, described upper end limiting stopper 3 and lower end limiting stopper 4 are separately fixed at the groove 3 li at screw rod body 1 two ends, described spring 5 is fixed on bottom upper end limiting stopper 3 and lower end limiting stopper 4, described upper end limiting stopper 3 and lower end limiting stopper 4 are equipped with spacing preiection 6 and limiting stopper screw thread 7, described screw rod body 1 is provided with lead screw screw thread 8, described limiting stopper screw thread 7 and lead screw screw thread 8 communicate after being spliced into one, described upper end limiting stopper 3 is identical with the cross section radian of screw rod body 1 with the edge radian of lower end limiting stopper 4, and to be sliceablely integrated, distance between described upper end limiting stopper 3 and lower end limiting stopper 4 equals the distance between two nuts after locking.
The utility model leads to has offered groove at the two ends up and down of screw rod body, and in the groove at screw rod body two ends, upper end limiting stopper, lower end limiting stopper and spring structure have been installed respectively, therefore people use to when wearing screw rod, as long as two nuts are tightened, these two nuts will be blocked by upper end limiting stopper and lower end limiting stopper naturally, even if how machine vibrates nut again and also can not come loose or slippage like this.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
