Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of existing Lighting System with removable traveling vehicle frame;
Fig. 2 is the side schematic view of latch-locking frame in the preferred embodiment of the present invention;
Fig. 3 is the enlarged diagram of the junction B of latch-locking frame among Fig. 2.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.
See also Fig. 2, be the side schematic view of latch-locking frame in the preferred embodiment of the present invention.As shown in Figure 2, latch-locking frame provided by the invention is made up of main car frame 6 and vehicle wheel component 7.Key point of the present invention is the improvement on the connection mode of main car frame 6 and vehicle wheel component 7.In the present invention, main car frame 6 and vehicle wheel component 7 adopt split type.Vehicle wheel component 7 comprises two Universal castors and two directed wheel carriers.Two Universal castors constitute two front-wheels of vehicle frame, and two directional wheels are configured to two trailing wheels of vehicle frame.
In the present invention, be provided with fixed cover 8 at main car frame 6 sides.And the relevant position is provided with fixed leg 9 on the vehicle wheel component 7.Realize being connected of main car frame 6 and vehicle wheel component 7 by fixed leg 9 being plugged in the fixed cover 8.In preferred embodiments more of the present invention, vehicle wheel component 7 comprises wheel and wheel carrier, and fixed leg 9 vertically is arranged on the wheel carrier, and described fixed cover 8 also vertically is provided with.The sidewall correspondence of fixed leg 9 and fixed cover 8 is offered through hole radially, simultaneously by realizing axial restraint in the position, hole of bolt device 10 being inserted described fixed leg 9 and fixed cover 8 sidewalls.
See also Fig. 3, be the enlarged diagram of the junction B of latch-locking frame among Fig. 2.As shown in Figure 3, this bolt device 10 comprises pin tube 11, guide 12, latch 13, locating dowel pin 14 and spring 15.Wherein, pin tube 11 is fixed on the fixed cover 8, and corresponding with the position, hole on fixed cover 8 and the fixed leg 9.Guide 12 is socketed on the pin tube 11.In preferred embodiments more of the present invention, be provided with screw thread in the guide 12, pin tube 11 outside faces also are provided with screw thread, thereby make that guide 12 and pin tube 11 can be fixing by being threaded.Latch 13 comprises pin rod 131 and pin handle 132.The through hole of pin rod 131 by guide 12 penetrated in the pin tube 11, and pass through hole on fixed cover 8 and the fixed leg 9, thereby will realize axial restraints fixed leg 9 and fixed cover 8.Locating dowel pin 14 is arranged on the latch 13, vertically inserts in the through hole of pin rod 131 of latch 13.Spring 15 is socketed on the latch 13, and the two ends of spring 15 are connected to respectively on the inner bottom surface and locating dowel pin 14 of guide 12.In pin tube 11, be provided with step surface 111.Bolt device 10 is when locking fixed cover 8 and fixed leg 9, because the elastic reaction of spring 15, locating dowel pin 14 is positioned at the via bottoms of pin tube 11, so the end of pin rod 131 is inserted in fixed cover 8 and the fixed leg 9 it is realized axial restraint.When needs dismounting latch-locking frame, the pin handle 132 of pulling latch 13 overcomes the elastic force of spring 15, locating dowel pin 14 will outwards move to step surface 111 outsides, rotate pin handle 132 this moment, make the direction of locating dowel pin 14 change, unclamp pin handle 132 this moment, because the elastic force effect of spring 15 is connected to locating dowel pin 14 on the step surface 111.By said process latch 13 is realized the location, thereby remove locking fixed cover 8 and fixed leg 9.
Therefore, when vehicle frame is installed, main car frame 1 is manually mentioned, the fixed leg 9 with Universal castor and directed wheel carrier inserts in the fixed cover 8 of main car frame 1 side respectively, has so just realized basic fixed demand.Be the phenomenon that guarantees that wheel carrier can not occur axially deviating from when the walking of rough road surface, at bolt device 10 of fixed cover 8 external weldings, the pin rod 131 with latch 13 during use inserts the position, hole that is provided with on fixed covers 8 and the fixed leg 9, can realize axial restraint.The pin handle 132 of pulling latch 13 when needing dismounting, the direction of rotation pin handle 132 is extracted pin rod 131, can take off vehicle wheel frame.
As mentioned above, this vehicle frame is more reliable than screw connection structure with the mode that is linked and packed of wheel carrier, and fixed leg 9 is difficult for taking place the bendings distortion, and fixed leg 9 is difficult for deviating from from fixed cover 8, and intensity is enough.Latch-locking frame provided by the invention can be used as the traveling vehicle frame of portable lighting light fixture, loads electrical generator 30.In preferred embodiments more of the present invention, can also be equipped with pulley 40 on the main car frame 6, thereby vehicle frame can be walked in orbit.Therefore, vehicle frame provided by the invention can carry medium-and-large-sized lighting installation, also can carry the equipment that other need move, even is used for Transhipment Cargo etc.
The present invention is described according to specific embodiment, but it will be understood by those skilled in the art that when not breaking away from the scope of the invention, can carry out various variations and be equal to replacement.In addition, for adapting to the specific occasion or the material of the technology of the present invention, can carry out many modifications and not break away from its protection domain the present invention.Therefore, the present invention is not limited to specific embodiment disclosed herein, and comprises that all drop into the embodiment of claim protection domain.
