Abstract
The invention discloses a U-shaped pin fastening structure which comprises a U-shaped body and a guide column. The U-shaped body comprises a first supporting leg, a second supporting leg and a connection bent portion. The two ends of the connection bent portion extend outwards respectively to form the first supporting leg and the second supporting leg arranged in parallel, the guide column is fixed to the bottom of the connection bent portion, and the first supporting leg and the second supporting leg are parallel to the guide column and symmetrically arranged with the guide column as the center. The guide column comprises a top column, a middle column and a bottom column, the top column, the middle column and the bottom column are sequentially connected, the top column is fixedly connected with the connection bent portion, the diameter of the bottom column is smaller than that of the middle column, external threads are arranged on the periphery of the middle column, and a fastening nut is arranged on the middle column through the external threads in a connection and cooperation mode. The U-shaped pin fastening structure can improve installation accuracy and installation efficiency and can improve the strength of the whole structure.
Description
Technical field
The present invention relates to technical field of fastening, relate in particular to a kind of U-shaped and lock fixing structure.
Background technique
In prior art, belt conveyor is widely used in the transportation of industrial material, between the fuselage of current belt conveyor and longeron, generally adopt bolt and nut to connect, in installing and using process, the connection reliability of belt conveyor is poor, efficiency of assembling is low, labor intensity is large.How to design a kind ofly for connecting the fuselage of belt conveyor and the fastening structure of longeron, become those skilled in the art's technical problem urgently to be resolved hurrily.
Summary of the invention
In order to solve the technical problem existing in background technique, a kind of U-shaped that the present invention proposes locks fixing structure, not only can increase installation precision and installation efficiency, and can increase integrally-built intensity.
The present invention proposes a kind of U-shaped and locks fixing structure, comprise U-shaped matrix and guide pillar, U-shaped matrix comprises the first supporting leg, the second supporting leg be connected turn of bilge, connection turn of bilge two ends stretch out respectively and form the first supporting leg and the second supporting leg being arranged in parallel, guide pillar is fixed on and connects turn of bilge bottom, the first supporting leg, the second supporting leg is parallel with guide pillar and be arranged symmetrically with centered by guide pillar, guide pillar comprises fore-set, center pillar and foundation, fore-set, center pillar and foundation successively connection and fore-set be connected turn of bilge and be fixedly connected with, the diameter of foundation is less than the diameter of center pillar, center pillar periphery is provided with outside thread, tightening nut connects cooperation by outside thread and is arranged on center pillar.
Preferably, the first supporting leg front end and the second supporting leg front end keep level.
Preferably, the periphery of the first supporting leg front end and the second supporting leg front end is provided with outside thread.
U-shaped of the present invention locks fixing structure not only can be increased installation precision and installation efficiency but also can increase integrally-built intensity.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of U-shaped that the present invention proposes locks fixing structure.
