Description

Protective net type tool box of semitrailer

Technical Field

The utility model belongs to the technical field of the semitrailer, concretely relates to semitrailer protection net formula toolbox.

Background

A semitrailer is a trailer whose axle is placed behind the center of gravity of the vehicle and which is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. The semitrailer is generally a three-axle semitrailer, and the semitrailer is classified into an eleven-meter-bin-column semitrailer, a thirteen-meter-bin-column semitrailer, a low-bed semitrailer and the like, and is a heavy transport vehicle connected with a semitrailer head through a traction pin. The semitrailer is generally provided with a tool box for placing some common maintenance tools and the like. However, most tool boxes in the prior art are of a relatively closed hexahedral box type structure, and are independently arranged beside the side protective guard of the semitrailer, so that the tool boxes are small in volume and not beneficial to placing of large and long tools, the length of the side protective guard is limited to prevent the side protective guard from protecting the side face of the bottom of the frame for smooth taking and placing of the tools, and the space utilization rate of the inner side of the side protective guard is low and needs to be improved.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a semitrailer protection net formula toolbox locates the rail guard inboard with the toolbox, and the make full use of space had both guaranteed the effect of rail guard, can increase the toolbox volume again to solve that current semitrailer toolbox volume is little, space utilization is low, influence side rail guard role scheduling problem.

In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a semitrailer protection net formula toolbox, includes vertical a plurality of bracing pieces that set up in frame bottom side, one side that the bracing piece is close to the frame is equipped with the toolbox frame, toolbox frame top surface and the equal opening setting in one side that is close to the bracing piece, the rest all is equipped with the protection network, one side that the frame was kept away from to the bracing piece is equipped with the rail guard, the both ends and the sill bar of the ejector pin of rail guard are all fixed on corresponding bracing piece, the middle section and the other both ends disconnection and the closure of the ejector pin of rail guard are connected, and the bottom in this middle section forms the chamber door through a plurality of connecting rods and sill bar are articulated, the equal fixed connection in one side that the bracing piece was kept away from at the top at toolbox frame both ends is on the frame bottom, equal.

Preferably, the tool box frame is of a rectangular frame type structure.

Preferably, the middle section of the ejector rod of the guard rail is connected with the two ends of the ejector rod of the guard rail in a locking manner through a lock catch.

Preferably, the connecting rods are hinged to the bottom rod through hinges, and a plurality of transverse baffles are connected between every two adjacent connecting rods.

The utility model has the advantages that: the utility model relates to a rationally, simple structure changes the toolbox into by the side of rail guard and locates the rail guard inboard, and the inboard space of make full use of rail guard need not shorten the rail guard, under the effect that does not influence the rail guard, can the whole volume of greatly increased toolbox, and the instrument of being convenient for especially getting of longer, great instrument is put, reinforcing convenience. Meanwhile, the tool box is changed into an open protective net type frame structure from an original relatively closed hexahedral box type structure, and the protective guard is directly changed into a box door of the tool box, so that the protective guard not only plays a role in protecting a vehicle frame, but also can be used as the box door to limit and protect tools in the tool box, further convenience is brought to carrying and taking and placing of the tools, and convenience in use of the tool box is improved.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1 to 4, a protective net type tool box for a semitrailer comprises a plurality of support rods 2 vertically arranged on the bottom side surface of a frame 1 for erecting and supporting the tool box and a protective guard 3. One side that bracing piece 2 is close to frame 1 is equipped with toolbox frame 11, is used as the main container of placement tool, and it is cuboid type frame structure, and its top surface and the equal opening setting of one side that is close to bracing piece 2, and the remaining face all is equipped with protection network 8, changes the toolbox into open protection network formula frame structure by original relative confined hexahedron box structure (as shown in fig. 5), can be further convenient for carrying and getting of instrument and put, improves the use convenience of semitrailer toolbox. The side of the support rod 2 far away from the vehicle frame 1 is provided with a protective guard 3, the two ends of the top rod 10 and the bottom rod 5 of the protective guard 3 are fixed on the corresponding support rod 2, the middle section of the top rod 10 of the protective guard 3 is disconnected with the two ends thereof and is connected in a locking manner, the bottom of the middle section is hinged with the bottom rod 5 through a plurality of connecting rods 7, so as to form a box door of the tool box, the sides of the tops of the two ends of the tool box frame 11 far away from the support rod 2 are fixedly connected on the bottom of the vehicle frame 1, the two ends of the tool box frame 11 and the side of the bottom thereof near the support rod 2 are fixedly connected on the corresponding support rod 2 and the bottom rod 5, thus, the tool box is changed from the side (as shown in figure 5) originally positioned on the protective guard 3 to the inner side of the protective guard 3, the inner space of the, the tool box is convenient to take and place tools, particularly longer and larger tools, convenience is improved, the original relatively-closed hexahedral box type tool box 12 is changed into an open protective net frame type tool box, the protective guard 3 is directly changed into a box door of the tool box, the protective guard 3 has the protective effect on the frame 1, the tools in the tool box can be limited and protected by the box door, tools can be further conveniently carried, taken and placed, and the use convenience of the tool box is improved.
