It changes；In addition, common bolt uses solid construction, but the bolt of solid construction there are overall weights larger, manufacturing cost phase
To higher.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of dismountable hollow bolt, just
In dismounting and change, weight and manufacturing cost are reduced.
To achieve the above object, the utility model proposes a kind of dismountable hollow bolt, including bolt head, screw rod,
Gasket, the top of the screw rod are equipped with bolt head, and the screw rod bottom centre position edge is axially arranged with an empty slot, the bolt
Screw rod fixing groove is equipped in head, the screw rod fixing groove includes fixing groove top and fixing groove lower part, in the fixing groove top
Equipped with Fixed latches, the screw rod includes screw rod top and screw rod lower part, and the screw rod top sets that there are two fixation holes, described solid
Bolt is determined through fixation hole, and the medial surface and lateral surface of the screw rod lower part are equipped with screw thread.
Preferably, the Fixed latches include the locating plate in latch body and both sides of the face, the latch body and
It is to be detachably connected between locating plate.
Preferably, the outer diameter of the gasket is less than the outer diameter of bolt head.
Preferably, the screw thread includes internal screw thread and external screw thread, the internal screw thread is located on the medial surface of screw rod, described
External screw thread is located on the lateral surface of screw rod.
The utility model has the beneficial effects that a kind of dismountable hollow bolt of the utility model, structure is simple, solves existing
There is the problem that some bolts are non-dismountable and solid bolt overall weight is larger, by the parts such as bolt head, screw rod, gasket group
At screw rod top can be inserted into the screw rod fixing groove of bolt head bottom, and be fixed bolt and fixed across fixation hole, convenient for tearing open
It unloads, assemble and fixation, suitable replacement in a variety of situations use；Screw rod bottom centre position edge is axially arranged with one
A empty slot alleviates bolt overall weight, reduces production cost.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
