Detailed description of the invention
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
A lot of details are set forth in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here and implement, and therefore the utility model is not subject to the restriction of following public specific embodiment.
Secondly, the utility model is described in detail in conjunction with schematic diagram, in the time that the utility model embodiment is described in detail in detail; for ease of explanation; the section-drawing of indication device structure can be disobeyed general ratio and be done local amplification, and described schematic diagram is example, and it should not limit the scope of the utility model protection at this.In addition in actual fabrication, should comprise, the three-dimensional space of length, width and the degree of depth.
Below in conjunction with drawings and Examples, the technical solution of the utility model is described.
As shown in Figure 1, be the structural representation of a kind of dolly connecting device of the present embodiment.
In the present embodiment, this dolly connecting device comprises towing hook 10 and snap close.
One end of towing hook 10 is flexibly connected with fixed support 11, and the other end has bonnet lock hole 101.Concrete, as shown in Figure 1, this fixed support 11 can be U-shaped support, the bottom of this fixed support 11 is fixedly connected on dolly by modes such as welding.One end of towing hook 10 can be fixed with rotating shaft 12, and this rotating shaft 12 is rotatably connected between the two side of fixed support 11, and towing hook 10 can turn to the different angles such as horizontal or vertical along with rotating shaft 12.
In the time that towing hook 10 does not use, the space taking in order to reduce towing hook 10, is convenient to towing hook 10 and stores up, and on the two side of fixed support 11, vertically respectively has a long waist-shaped hole 111 in the installation site of rotating shaft 12, and this rotating shaft 12 can be slided along this long waist-shaped hole 111.In the time not using towing hook 10, rotating shaft 12 is slid into bottom, hole along this long waist-shaped hole 111, towing hook 10 is vertically placed.
As Fig. 1, shown in Fig. 2, stability while vertically placement in order to increase towing hook 10, also in order to improve the stability of towing hook 10 in the time being connected with snap close, below rotating shaft 12, can also be provided with supporting bracket 13, the installation site of this supporting bracket 13 can be in the U-shaped groove of fixed support 11, also be between the two side of fixed support 11, and this supporting bracket 13 can be in the time that towing hook 10 uses, also be that the bonnet lock hole 101 of towing hook 10 is while snapping in snap close, can play a supporting role to towing hook 10, the width of this supporting bracket 13 is more than or equal to the width of towing hook 10.And, between supporting bracket 13 and the bottom of fixed support 11, can also there is the gap that allows towing hook 10 vertically to insert.As shown in Figure 3, in the time that towing hook 10 is vertically placed, towing hook 10 can insert between supporting bracket 13 and fixed support 11, thereby can increase stability when towing hook 10 is vertical to be placed.
Towing hook 10 can also be set up reinforced rib between bonnet lock hole 101 and rotating shaft 12, and towing hook 10 can be to be formed by round steel welding.
Again as shown in Figure 1, snap close can comprise elbow pin 21 and be connected to the connection bracket 22 on another dolly.Elbow pin 21 is flexibly connected with connection bracket 22, concrete, and connection bracket 22 has the groove 221 that holds bonnet lock hole 101, and on the two side of the groove 221 of connection bracket 22, correspondence has long waist-shaped hole 222; The crooked position of elbow pin 21 is fixed with rotating shaft 23, on rotating groove 221 sidewalls that are connected to connection bracket 21 of rotating shaft 23, it can be specifically a side that is connected to long waist-shaped hole 222, elbow pin 21 can rotate along with rotating shaft 23, when the bonnet lock hole 101 of towing hook 10 inserts groove 221 when interior, one end of elbow pin 21 through long waist-shaped hole 222 at the interior insertion of groove 221 and separating lock button hole 101.
Dolly connecting device based on said structure, in the time that dolly need to be organized into groups, operating personal puts down the towing hook of rear car 10, it relies on the supporting role of supporting bracket 13 to keep horizontality, as shown in Figure 2, touch rear car, the bonnet lock hole 101 of rear car is moved towards groove 221 directions of the connection bracket 22 of front truck snap close, rear car towing hook 10 drives on the elbow pin 21 of front truck and turns over, as shown in Figure 4, until bonnet lock hole 101 pushes after groove 221, elbow pin 21 recovers vertical state under Gravitative Loads, insert in bonnet lock hole 101 one end of elbow pin 21, realize the quick marshalling of dolly, again by tractor truck traction circulation.
In the time of needs release dolly, operating personal is to the light La Benche of front truck direction, make the towing hook 10 of this car keep a distance with the elbow pin 21 of front truck, manually, turn over the elbow pin 21 of front truck, elbow pin 21 23 rotates around the shaft, elbow pin 21 separating lock button holes 101, then, promote backward this car, realize the release of this car.Finally, will on the towing hook of this car 10, turn over 90 degree, the lower end in the long waist shaped hole 111 of lower insertion fixed support 11, towing hook 10 relies on the effect of contraction of supporting bracket 13 to keep vertical state, thereby reduces dolly taking space as shown in Figure 3.
As shown in Figure 5, the invention also discloses a kind of dolly of marshalling fast, the dolly that this dolly can be adjacent connects by above-mentioned dolly connecting device, this dolly itself also has above-mentioned towing hook 10 and snap close 20, lock towing hook 10 is fixed on a side of dolly by fixed support, snap close is fixed on by connection bracket the opposite side that this dolly is relative.It is identical with the open height of the connection bracket groove of snap close 20 that towing hook 10 is positioned over height on supporting bracket.
This dolly is connected with the snap close of front truck by towing hook 10 like this, is connected, thereby forms queue by snap close 20 with the towing hook of rear car.
Other parts and the existing dolly of this dolly are similar, and roller is equipped with in dolly bottom.
The utility model embodiment can realize the quick marshalling of dolly by above-mentioned connecting device, not only convenient operation has improved connection and release efficiency between dolly, and reduced the parking space that dolly takies, and has delicate structure, the advantage of low cost of manufacture.
In above embodiment, the shape of each parts and structure are only example, and non-limiting.And above each parts can also be replaced respectively with the element that other has identical function, to be combined to form more technical scheme, and these technical schemes of replacing rear formation all should be within the scope of technical solutions of the utility model protection.
The above, be only preferred embodiment of the present utility model, not the utility model done to any pro forma restriction.
Although the utility model discloses as above with preferred embodiment, but not in order to limit the utility model.Any those of ordinary skill in the art, do not departing from technical solutions of the utility model scope situation, all can utilize method and the technology contents of above-mentioned announcement to make many possible variations and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not depart from technical solutions of the utility model,, all still belongs in the scope of technical solutions of the utility model protection any simple modification made for any of the above embodiments, equivalent variations and modification according to technical spirit of the present utility model.
