Technical Field

[0001] This utility model relates to the field of transport vehicle technology, and in particular to a transport vehicle with a bracket that is easy to adjust at an angle. Background Technology

[0002] "Sound system" is short for "sound system," which refers to a complete set of equipment that can reproduce and play audio signals. With the development and progress of technology, people have more and higher requirements for the performance forms and venues of singing and dancing. Sound systems are constantly being improved and perfected to meet people's needs.

[0003] Stage speakers are typically heavy and difficult to move. Existing solutions often involve placing them on transport vehicles with casters. However, due to their weight, these vehicles may tip over during transport due to instability, causing damage. Furthermore, conventional transport vehicles cannot adjust the orientation of the speakers in multiple directions, limiting the range of sound effects that can be achieved. Summary of the Invention

[0004] In view of this, the present invention provides a transport vehicle with a bracket that is conveniently adjustable in angle, in order to solve the above-mentioned technical problems.

[0005] A transport vehicle with a conveniently adjustable bracket includes a vehicle body, two adjustable brackets mounted on the vehicle body, and two speakers mounted on the vehicle body. The vehicle body includes a base, and each adjustable bracket includes two adjustable bases fixed to the base, and a bracket inserted into the two adjustable bases. The two adjustable bases are spaced apart, and each adjustable base includes a connecting base plate, an insertion slot vertically mounted on the connecting base plate, a fixing shaft disposed within the insertion slot, and an adjusting slot disposed on the insertion slot. The insertion slot is vertically fixed to the connecting base plate and has an insertion opening at one end away from the connecting base plate. The fixing shaft, disposed within the insertion opening on the connecting base plate, is a cylindrical structure, and its axis is perpendicular to the insertion direction of the bracket into the insertion slot. The adjusting slot is a cutout on the side wall of the insertion slot. The adjusting slot has three U-shaped latches. One latch is aligned with the fixed rotating shaft on a straight line perpendicular to the connecting base plate. The other two latches are arranged at an angle to one side, with central angles of 15° and 30° respectively to the first latch. A slot communicating with the insertion port of the insertion groove is provided on the side of the 30° latch away from the fixed rotating shaft. The bracket includes two insertion rods inserted into the insertion groove, a connecting rod connecting the two insertion rods, and a top abutment connecting one end of the two insertion rods. The two insertion rods are parallel and spaced apart. Each insertion rod includes an insertion end, an insertion latch on the insertion end, and two snap-fit ​​protrusions on the insertion rod. The insertion end is located on the free end of the insertion rod away from the top abutment. The insertion end is rounded. The insertion latch is a notch on the insertion end. The snap-fit ​​protrusions are cylindrical protrusions located on both sides of the insertion rod perpendicular to the insertion direction.

[0006] Furthermore, the vehicle body includes multiple side plates connected to the base, and a top plate spaced apart from the base.

[0007] Furthermore, the side plate includes four lower side plates connected to the base, four upper side plates connected to the lower side plates, and a plurality of pull rings disposed on the upper side plates.

[0008] Furthermore, the lower side plate is vertically connected to the base and forms a rectangular box structure. The upper side plate is hinged to the lower side plate, and multiple upper side plates are vertically spliced ​​together. The pull ring is disposed on the outer side wall of the upper side plate.

[0009] Furthermore, the top plate is vertically connected to the four upper side plates, and the connection is made by hinges.

[0010] Furthermore, the length of the insertion slot is greater than the path of movement of the buckle protrusion when it is lifted to switch between different slots.

[0011] Furthermore, the connecting rod is perpendicularly connected to the two insertion rods.

[0012] Furthermore, the abutment top includes an abutment rod arranged parallel to the connecting rod, and an elastic structure wrapped around the abutment rod, the elastic structure being made of sponge.

[0013] Compared with existing technologies, the transport vehicle with a conveniently adjustable bracket provided by this utility model, by setting up the vehicle body to carry the speaker, allows for free movement of the speaker's position. The bracket also serves to support and limit the speaker, preventing it from swaying or even tipping over during movement due to instability. Furthermore, by including the adjustable base and insertion rod, the angle at which the insertion rod is inserted into the vehicle body can be adjusted, thereby adjusting the speaker's angle and orientation in three dimensions.

[0018] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0019] like Figures 1 to 4The diagram shows a structural schematic of a transport vehicle with an adjustable bracket according to this invention. The transport vehicle includes a vehicle body 10, two adjustable brackets 20 mounted on the vehicle body 10, and two speakers 30 mounted on the vehicle body 10. It is conceivable that the transport vehicle with an adjustable bracket may also include other functional modules such as casters, locks, etc., which are technologies well known to those skilled in the art and will not be described in detail here.

[0020] The vehicle body 10 includes a base 11, a plurality of side plates 12 connected to the base 11, and a top plate 13 spaced apart from the base 11.

[0021] The base 11 includes a base plate and multiple casters mounted on the base plate. The base plate can be a rectangular plate, serving as the foundation for supporting the adjustment bracket 20 and the speaker 30. The casters are located at the four corners of the base plate, supporting the base plate and allowing the vehicle body 10 to be pushed.

[0022] The side plate 12 includes four lower side plates 121 connected to the base 11, four upper side plates 122 connected to the lower side plates 121, and a plurality of pull rings 123 disposed on the upper side plates 122.

[0023] The lower side plate 121 is vertically connected to the base 11 and forms a rectangular box structure to house the speaker 30. The upper side plate 122 is hinged to the lower side plate 121, and multiple upper side plates 122 are vertically joined together. In use, the upper side plate 121 is opened to fully expose the speaker 30 for amplification, while the lower side plate 121 acts as a barrier and limiter. The pull ring 123 is located on the outer wall of the upper side plate 122 for the user to pull the base 11 to move the speaker 30 quickly.

[0024] The top plate 13 is vertically connected to the four upper side plates 122, and the connection is made by a detachable hinge so that the top plate 13 can be disassembled during use.

[0025] Each of the adjustment brackets 20 includes two adjustment bases 21 fixed on the base 11, and a bracket 22 inserted into the two adjustment bases 21.

[0026] Two adjustment bases 21 are spaced apart. Each adjustment base 21 includes a connecting base plate 211, an insertion slot 212 vertically disposed on the connecting base plate 211, a fixed rotating shaft 213 disposed in the insertion slot 212, and an adjustment slot 214 disposed on the insertion slot 212.

[0027] The connecting base plate 211 is a rectangular plate, which is fixed to the base 11 by fasteners so that the adjusting bracket 20 can be fixed to the base 11.

[0028] The insertion slot 212 is vertically fixed to the connecting base plate 211, and an insertion port is provided at one end away from the connecting base plate 211 for inserting the bracket 22 into it. The insertion slot 212 may be integrally formed with the connecting base plate 211.

[0029] The fixed rotating shaft 213 is disposed in the insertion port of the connecting base plate 211. It is a cylindrical structure and its axis is perpendicular to the insertion direction of the bracket 22 into the insertion groove 212, so that the insertion rod 221 described below can be engaged and rotated when inserted. It will be described in detail below in conjunction with the corresponding structure of the bracket 22.

[0030] The adjusting slot 214 is a hollow notch on the side wall of the insertion slot 212. The adjusting slot 214 contains three U-shaped latches. One latch is aligned with the fixed pivot 213 on a straight line perpendicular to the connecting base plate 211. The other two latches are arranged obliquely on one side, with central angles of 15° and 30° respectively to the first latch, thus providing three different latching positions for the bracket 22. Furthermore, a slot communicating with the insertion opening of the insertion slot 212 is provided on the side of the 30° latch away from the fixed pivot 213 to allow for clearance when the bracket 22 is inserted. This will be described in detail below in conjunction with the corresponding structure of the bracket 22.

[0031] The bracket 22 includes two insertion rods 221 inserted into the insertion slot 212, a connecting rod 222 connecting the two insertion rods 221, and a top 223 connecting one end of the two insertion rods 221.

[0032] Two insertion rods 221 are arranged parallel to each other and spaced apart. Each insertion rod 221 includes an insertion end 2211, an insertion slot 2212 on the insertion end 2211, and two latching protrusions 2213 on the insertion rod 221. The insertion end 2211 is located on the free end of the insertion rod 221 away from the abutment 223, and the insertion end 2211 is rounded to facilitate insertion into the insertion slot 212. The insertion slot 2212 is a notch on the insertion end 2211. When the insertion rod 221 is inserted into the insertion slot 212, the fixing shaft 213 will engage with the insertion slot 2212, allowing the insertion rod 221 to rotate about the fixing shaft 213. The latching protrusion 2213 is a cylindrical protrusion located on both sides of the insertion rod 221 perpendicular to the insertion direction. When the insertion rod 221 is inserted into the insertion slot 212, it passes through the slot of the adjusting slot 214 and engages with the latch within the adjusting slot 214, thereby restricting the rotation of the insertion rod 221 around the fixed pivot 213. Simultaneously, the latching protrusion 2213 can be engaged with latches at different angles to adjust the tilt angle of the insertion rod 221. Correspondingly, the length of the insertion latch 2212 is greater than the path of movement of the latching protrusion 2213 when it is lifted to switch between different latches, thus preventing the fixed pivot 213 from disengaging from the insertion latch 2212 when switching angles.

[0033] The connecting rod 222 is perpendicularly connected to the two insertion rods 221 to stabilize the structure.

[0034] The abutment top 223 includes an abutment rod arranged parallel to the connecting rod 222, and an elastic structure wrapped around the abutment rod. The elastic structure can be made of flexible materials such as sponge, and plays a buffering and protective role when the speaker 30 leans against or abuts against the abutment top 223.

[0035] The speaker 30 is an amplifier device with an isosceles trapezoidal housing, both the bottom and top of which are inclined. When placed, the speaker 30 is supported by pads on the base 11, which abut against the top 223. At this time, the insertion rod 221 is perpendicular to the base 11. When using the speaker 30, the insertion angle of the insertion rod 221 can be adjusted so that the speaker 30 leans against the rod, changing its orientation and thus adjusting the amplifier's performance.

[0036] Compared with the prior art, the transport vehicle with a conveniently adjustable bracket provided by this utility model, by setting the vehicle body 10 to carry the speaker 30, allows the speaker's position to be moved freely. The bracket 22 provides support and limits the speaker 30, preventing it from swaying or even tipping over during movement due to instability. Simultaneously, by setting the adjustable base 21 and the insertion rod 221, the angle of the insertion rod 221 inserted into the vehicle body 10 can be adjusted, thereby adjusting the angle of the speaker 30 and achieving adjustment of its orientation in three-dimensional height.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
