Description

Trailer hook type flag frame Technical Field The utility model relates to the technical field of vehicle flag frames, in particular to a trailer hook type flag frame. Background In a vehicle towing scene, a trailer hook type flag frame is widely applied to vehicles such as a motor home and a trailer and used for displaying various identification flags, decorative flags or warning flags and the like, the existing trailer hook type flag frame generally comprises a trailer hook receiver connected with a vehicle frame and a base arranged on the trailer hook receiver, and a flag cylinder is arranged on the base for accommodating a flag pole of the flag; on the other hand, the traditional fixing structure (such as an elastic buckle or a bolt clamping piece) lacks linkage fit with the internal structure of the flag cylinder, and cannot automatically adjust clamping force according to external force change, so that when the flagpole is subjected to transverse or longitudinal impact force, the clamping force of the traditional fixing structure cannot be synchronously enhanced, and stable constraint on the flagpole is lost. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a trailer hook type flag frame, which aims to solve the problems that the traditional trailer hook type flag frame has lower fixing strength to a flagpole of a flag and is easy to shake or fall off in the flag frame when the flagpole is impacted by acting force. In order to achieve the above purpose, the utility model provides a trailer hook type flag rack, which comprises a trailer hook receiver and a base, wherein the trailer hook receiver is used for being connected with an external vehicle frame, the base is arranged on the trailer hook receiver, vertical plates are vertically arranged on the base relatively, flag barrels are arranged at two ends of the vertical plates along the height direction of the base, insertion holes for inserting flagpoles of external flags are penetrated through the flag barrels along the height direction of the flag barrels, fixing pieces for fixing the flagpoles placed in the insertion holes are arranged on the peripheral wall of the flag barrels, and loading pieces and positioning pieces for guiding and positioning the flagpoles are arranged in the flag barrels, wherein the loading pieces are used for being in linkage fit with the fixing pieces to clamp and limit the flagpoles. The technical scheme is beneficial in that the vertical layout of the base and the vertical plate in the technology forms a stable mechanical supporting structure, torque generated by external force such as windage and the like of the flag is effectively dispersed, structural deformation caused by uneven stress is avoided, the positioning piece arranged in the flag cylinder can carry out three-dimensional positioning on the flag pole through the accurate guide structure, the vertically centered state is ensured when the flag pole is inserted, the shaking hidden trouble caused by mounting deviation in the traditional structure is eliminated, meanwhile, the linkage fit mechanism of the loading piece and the fixing piece has dynamic clamping characteristics, when the flag pole is subjected to external impact force (such as vehicle jolt and strong wind load), the loading piece generates self-adaptive clamping force through elastic deformation and forms double constraint with mechanical locking of the fixing piece, so that the flag pole can keep initial fixed strength in the jack, impact energy can be absorbed through the buffer effect of the loading piece, and stress concentration caused by rigid connection is avoided. The utility model further provides that two connecting holes are formed in the flag cylinder, the two connecting holes are communicated with the jack, a fixing bolt is connected in the connecting holes in a threaded mode, a rotating wheel is arranged at the tail end of the fixing bolt, the initial end of the fixing bolt is an abutting end which is used for being placed into the jack and abutted to the peripheral wall of an external flagpole, and the fixing bolt is a fixing piece. The technical scheme has the advantages that the two symmetrically arranged connecting holes are matched with the fixing bolts in threaded connection in the technology to form the two-point radial clamping structure for the flagpole, compared with a traditional single-point fixing mode, the clamping force distribution is more uniform, deflection or deformation of the flagpole caused by single-side stress can be effectively avoided, an operator can rotate the rotating wheel to put in or take out the fixing bolts, and then the flagpole is rapidly positioned and primarily fixed. The utility model further provides that the peripheral wall of the flag cylinder is integrally connected with a vertical block, a loading cavity is formed in the vertical block in a hollow mode, the loading cavity is communicated with the j
