Abstract

The utility model relates to a kind of bolt, comprise screw rod (3), it is characterized in that: one end of described screw rod (3) is provided with the thread bush (1) screwing on screw rod (3), the outer cover of described thread bush (1) is connected to bearing (2), between described bearing (2) and screw rod (3) the other end, is connected with multiple stalloys (4).Under the utility model case of emergency, use, be suitable for multiple aperture, connect effect better.

Description

Bolt
Technical field
The utility model relates to a kind of link, specifically a kind of bolt.
Background technique
Bolt is a kind of widely used fastening connection piece, more and the standardization of specification, different apertures coordinates the bolt of dimension just can play the effect that is fastenedly connected preferably, can not find but be but usually in an emergency down in daily life the phenomenon that is applicable to bolt, particularly play out of doors, when outdoor camping in the connection of outdoor gear, therefore having under a kind of case of emergency and use, be suitable for the bolt of multi-aperture, is that people comparatively thirst for.
Summary of the invention
Technical problem to be solved in the utility model is: provide under a kind of case of emergency and use, be suitable for multiple aperture, connect the good bolt of effect.
The technological scheme that the utility model adopts is: a kind of bolt is provided, comprise screw rod, one end of described screw rod is provided with the thread bush screwing on screw rod, and the outer cover of described thread bush is connected to bearing, between described bearing and the screw rod the other end, is connected with multiple stalloys.
Adopt after above structure, compared to the prior art the utility model bolt has following advantage: owing to being connected with multiple stalloys between bearing and the screw rod the other end, bearing housing is connected on the outside of thread bush, when use, screw rod is placed in attachment hole, rotation is located at the thread bush on screw rod one end, thread bush is moved to the screw rod the other end, now the bearing on thread bush will drive stalloy to move to the screw rod the other end, by large the support of stalloy middle part, support large stalloy and be close to the hole wall of attachment hole, reach the effect that tensioner connects, when dismounting, rotation thread bush, make thread bush away from the screw rod the other end, bearing on thread bush will drive stalloy, draw stalloy in, the utility model bolt can use under case of emergency, support by stalloy is large or draw in, be applicable to the connection of different pore size, connect effect better.
As improvement, the outer surface of described stalloy is provided with screw thread, and screw thread is set, and is connected more firm after support is large with hole wall.
As improvement, described stalloy is 6 ~ 8, and magnitude setting is reasonable, and easy accessibility is guaranteed effect.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model bolt.
In figure, 1, thread bush, 2, bearing, 3, screw rod, 4, stalloy.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model bolt, comprise screw rod 3, one end of screw rod 3 is provided with the thread bush 1 screwing on screw rod 3 one end, thread bush 1 is a sleeve pipe, internal thread is set in sleeve pipe, screw thread on internal thread and screw rod 3 matches, the outer cover of thread bush 1 is connected to bearing 2, namely the inner ring of bearing 2 is socketed on the outer surface of thread bush 1, bearing 2 and thread bush 1 tight fit connection, between bearing 2 and screw rod 3 the other ends, be connected with multiple stalloys 4, the two ends of stalloy 4 can be welded on respectively on one end of screw rod 3 and the outer ring of bearing 2, stalloy 4 is galleyproof type, the outer surface of stalloy 4 is provided with screw thread, namely be provided with screw thread back to the face of screw rod 3, after support is large, be connected more firm with hole wall, stalloy 4 is 6 ~ 8, be centered around the periphery of screw rod 3.
The utility model is in the time of concrete use, bolt is placed in attachment hole, the thread bush 1 of rotary screw 3 one end, thread bush 1 is moved to screw rod 3 the other ends, now the bearing 2 on thread bush 1 will drive stalloy 4 to move to screw rod 3 the other ends, now the middle part of stalloy 4 will be supportted greatly, support large stalloy 4 and be close to the hole wall of attachment hole, reach the effect that tensioner connects, when dismounting, rotation thread bush 1, make thread bush 1 away from screw rod 3 the other ends, bearing 2 on thread bush 1 will drive stalloy 4 away from screw rod 3 the other ends, stalloy 4 is drawn in, be less than while connecting aperture and can take out, for ensureing to connect effect, the utility model can also screw on nut on screw rod 3, nut is spun on screw rod 3 near thread bush 1, for the reinforcing location of double thread cover 1.
