Abstract
The utility model relates to a kind of split type clamping bolt, comprise bolt head and screw rod, screw rod lower end is provided with two gap, gap from top to bottom width increases gradually, square through hole is provided with in screw rod, bolt head lower surface is fixedly connected with the fixing rod corresponding with through hole, through-hole wall offers fixed groove between adjacent gap, the corresponding fixed groove position of fixing rod sidewall is fixedly connected with fixing device corresponding with fixed groove, fixing rod inserts fixed groove by fixing device and is fixedly connected with screw rod, and gap is fixedly connected with closed by fixing rod with screw rod.Split type clamping bolt of the present utility model by by screw rod and bolt head partial installation, and arranges the gap for increasing screw diameter on screw rod, thus the anti-loose property of elevator bolt and theftproof performance greatly.
Description
Technical field
The utility model relates to a kind of split type clamping bolt.
Background technique
Current bolt is on the market with a long history, and structure is simple, and just simple screw thread is fixed, but be easy to that bolt occurs get loose long-time use, cause causing danger, and common threaded screw fasteners head and screw rod are integrative-structures, be easy to be dismantled by people, also dangerous.
Model utility content
The technical problems to be solved in the utility model is: for solving above-mentioned Problems existing, provides a kind of split type clamping bolt, solves plain bolt and easily gets loose and easy-off problem.
The utility model solves the technological scheme that its technical problem adopts: a kind of split type clamping bolt, comprise bolt head and screw rod, screw rod lower end is provided with two gap, gap from top to bottom width increases gradually, square through hole is provided with in screw rod, bolt head lower surface is fixedly connected with the fixing rod corresponding with through hole, through-hole wall offers fixed groove between adjacent gap, the corresponding fixed groove position of fixing rod sidewall is fixedly connected with fixing device corresponding with fixed groove, fixing rod inserts fixed groove by fixing device and is fixedly connected with screw rod, gap is fixedly connected with closed by fixing rod with screw rod.
Further, conveniently install, fixing rod cross-section area is identical with via area.
Further, in order to increase the service life, fixing rod sidewall is fixedly connected with wear-resistant anti-skid layer.
Further, in order to protect bolting face, screw rod upper surface is fixedly connected with rubber protection pad.
The beneficial effects of the utility model are, split type clamping bolt of the present utility model by by screw rod and bolt head partial installation, and arranges the gap for increasing screw diameter on screw rod, thus the anti-loose property of elevator bolt and theftproof performance greatly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side view of the present utility model.
1. bolt heads, 2. screw rod, 3. fixing rod, 4. fixing device in figure.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The split type clamping bolt of one as depicted in figs. 1 and 2, comprise bolt head 1 and screw rod 2, screw rod 2 lower end is provided with two gap, gap from top to bottom width increases gradually, square through hole is provided with in screw rod 2, bolt head 1 lower surface is fixedly connected with the fixing rod 3 corresponding with through hole, through-hole wall offers fixed groove between adjacent gap, the corresponding fixed groove position of fixing rod 3 sidewall is fixedly connected with fixing device 4 corresponding with fixed groove, fixing rod 3 inserts fixed groove by fixing device 4 and is fixedly connected with screw rod 2, fixing device 4 on fixing rod 3 injects through hole along fixed groove, by fixed groove and fixing device 4 clamping, drive screw rod 2 toward inside contracting, gap is fixedly connected with closed by fixing rod 3 with screw rod 2, screw rod 2 inner diameter is consistent from top to bottom, convenient installation, after installing, again bolt head 1 is extracted, bolt head 1 drives fixing rod 3 to extract together with fixing device 4, screw rod 2 is not because have pulling force, so outwards put on display, gap is caused again to open, increase the diameter bottom screw rod 2, thus loosen de-while because there is no bolt head, cannot rotate, also can be antitheft.
Further; conveniently install; fixing rod 3 cross-section area is identical with via area; further; in order to increase the service life; fixing rod 3 sidewall is fixedly connected with wear-resistant anti-skid layer; further; in order to protect bolting face; screw rod 2 upper surface is fixedly connected with rubber protection pad; split type clamping bolt of the present utility model by by screw rod 2 and bolt head 1 partial installation, and arranges the gap for increasing screw diameter on screw rod 2, thus the anti-loose property of elevator bolt and theftproof performance greatly.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
