The utility model has the advantages of be convenient for install hasp and connecting strip on the chassis under.
Description
Technical field
This utility model belongs to automobile emergency exit window field, the self-locking type connecting structure of especially a kind of emergency-exit window hasp and connection strap.
Background technology
On current motorbus, glass for vehicle window is mostly enclosed, generally all cannot open, and therefore, the ad-hoc location on automobile can install emergency-exit window.nullEmergency-exit window includes inside casing、The lower part such as inside casing and glass，Lower inside casing is provided with fitting recess，This fitting recess is provided with connection strap，Connection strap has been bolted hasp，When connection strap is connected with hasp，Connection strap have to be disassembled from fitting recess and just carry out device，Reason is: the through hole on the through hole of the screw portion of bolt setting on connection strap and hasp is connected with nut again，If being at this moment assembled in fitting recess again by connection strap screw on nut，When being screwed to close to when making hasp be fastened as a whole with connection strap，Owing to the head of bolt is in fitting recess，Clamping tool cannot be passed through clamped，At this moment screw on nut again，Bolt then followed by nut and rotates together with，Therefore，First connection strap is assembled in fitting recess and fastens hasp and connection strap again，Both cannot be fastened as a whole，Only disassemble and just can assemble，Thus cause assembling inconvenience，And when connection strap is first assembled in fitting recess by needs，Such structure is to meet the needs of assembling.
Summary of the invention
The purpose of this utility model is to provide the self-locking type connecting structure of a kind of emergency-exit window hasp and connection strap, and this utility model has the advantage being easy to that hasp and connection strap carry out install on lower underframe.
The technical scheme realizing this utility model purpose is as follows:
The self-locking type connecting structure of emergency-exit window hasp and connection strap, including hasp, connection strap, bolt and nut, hasp is provided with the first through hole, connection strap is provided with the second through hole, the bar portion of described bolt is connected with nut after the first through hole and the second through hole, one end of connection strap is provided with groove, the aperture of second through hole one end is positioned at the bottom land of groove, the head of bolt is at least partially situated in groove, the sidewall of bolt head has at least two points or face simultaneously tangent with two relative sidewalls of groove respectively.
Preferably, the head of described bolt is entirely located in groove.
Preferably, the head of described bolt is polygon.
Preferably, the head of described bolt is regular hexagon.
Preferably, the oral area of described groove is connected by joint face with the edge of connection strap, and this joint face includes the first joint face and the second joint face, and the first joint face is inclined-plane, and the second joint face is plane, and the first joint face is between the second joint face and groove mouth.
Have employed such scheme, the sidewall 21 sidewall of bolt head having at least two points or face relative with groove two respectively is simultaneously tangent.Such structure makes the head of bolt spacing by sidewall, in the process of nutting, the head of bolt cannot follow nut rotation, thus the head of bolt is formed self-locking, therefore, after connection strap can be arranged under emergency-exit window on underframe by such structure, then screw on nut, not only convenient but also rapidly hasp and connection strap are fastened as a whole.
Accompanying drawing explanation
Fig. 1 is the assembling schematic diagram of hasp and connection strap；
Fig. 2 is the schematic diagram of connection strap；
Hasp and connection strap are installed to the schematic diagram that emergency-exit window is costed by Fig. 3.
Detailed description of the invention
Shown in seeing figures.1.and.2, the self-locking type connecting structure of emergency-exit window hasp of the present utility model and connection strap, including hasp 1, connection strap 2, bolt 3 and nut 4, hasp 1 is provided with the first through hole (not shown), connection strap is provided with the second through hole, the bar portion of described bolt 3 is connected with nut 4 after the first through hole and the second through hole, one end of connection strap 2 is provided with groove 20, the aperture of second through hole one end is positioned at the bottom land of groove 20, the head of bolt 3 is at least partially situated in groove, preferably, the head of described bolt is entirely located in groove, so can increase the contact area of bolt head and recess sidewall 21.The oral area of described groove 20 is connected by joint face with the edge 22 of connection strap 2, this joint face includes the first joint face 23 and the second joint face 24, first joint face 23 is inclined-plane, second joint face 24 is plane, first joint face 23 is between the second joint face 24 and groove mouth, arrange the first joint face 23 to be advantageous in that, it is simple to reduce the degree of depth of groove 20, be then easy to assembling bolt 3.The sidewall 21 having at least two points or face relative with groove 20 two respectively on the sidewall of bolt 3 head is simultaneously tangent.The head of described bolt 3 is polygon, preferably, the head of described bolt 3 is regular hexagon, circumscribed diameter corresponding to this regular hexagon, width more than or equal to groove 20, thus can ensure that the sidewall 21 having at least two points or face relative with groove 20 two respectively on the sidewall of bolt 3 head is simultaneously tangent, thus the head of bolt 3 is spacing by sidewall 21, in the process of nutting, the head of bolt 3 cannot be followed nut 3 and be rotated, not only convenient but also hasp 1 and connection strap 2 are fastened as a whole rapidly.
As shown in Figure 3, after being connected with nut 4 after the bar portion of bolt 3 traverse the first through hole and the second through hole, in the tankage of the support that connection strap 2 is inserted on lower underframe 5, under the support of support, can to continuing screw on nut, thus connection strap 2 and hasp 1 being fastened as a whole on lower underframe 5.This attachment structure not only convenient should but also quick.
