[0036] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0037] Example 1:

[0038] like Figures 1 to 10As shown: a fishing box with a movable backrest, comprising a box body 1 and a box cover 2 hingedly arranged on the box body 1; one end of the box cover 2 is also provided with a first hole 21 and a second hole 22 arranged opposite to each other; the backrest 3 is pulled out and arranged in the first hole 21 and the second hole 22; the backrest 3 is composed of a fixed rod 31 and a movable rod 32 coaxially slidably arranged outside the fixed rod 31; in the non-working state, the backrest 3 is stored in the first hole 21 and the second hole 22; the backrest 3 also includes a locking module 35, which is fixedly arranged at one end of the fixed rod 31 away from the movable rod 32, for locking the backrest 3 at the insertion openings of the first hole 21 and the second hole 22 after the backrest 3 is pulled out; a linear reciprocating drive 33 is coaxially fixed in the fixed rod 31, for driving the movable rod 32 axially away from or close to the fixed rod 31; the power supply module 5 is embedded in the upper surface of the box cover 2.

[0039] When the backrest 3 is in the working state, the fixed rod 31 is a long rod with two hollow ends and open ends, and the movable rod 32 is a U-shaped tube set in a U shape. When the backrest 3 of the current fishing box needs to be used, the user first places the box body 1 at the fishing spot and grasps the far end of the backrest 3, that is, the end of the movable rod 32 away from the fixed rod 31, and pulls the backrest 3 out of the first insertion hole 21 and the second insertion hole 22 until the backrest 3 is completely pulled out of the box cover 2. The backrest 3 is limited and fixed at the insertion openings of the first insertion hole 21 and the second insertion hole 22 by adjusting the locking module 35, and the backrest 3 is locked to the required leaning angle by adjusting the locking module 35. Finally, the user sits on the fishing box and leans on the backrest 3. When it is found that the current support point of the backrest 3 is low, the linear reciprocating drive 33 can be driven by the adjusting controller to drive the movable rod 32 to move away from the fixed rod 31, so that the leaning height can be adjusted according to the user's leaning needs.

[0040] like Figure 7 and Figure 8 As shown: a slide groove 23 is respectively provided on one side of the first socket 21 and the second socket 22. The slide groove 23 is provided on one side of the first socket 21 and the second socket 22 in parallel along the long side direction of the box cover 2 and is connected to the first socket 21 and the second socket 22; a notch 24 is also provided at the insertion port of the first socket 21 and the second socket.

[0041] In the working state, the sliding groove 23 is used to guide the backrest 3 to be pulled out from the first hole 21 and the second hole 22, so that the backrest 3 is always in a unified posture in the sliding state; the notch 24 opened at the insertion port of the first hole 21 and the second hole 22 is used to accommodate the U-shaped bend of the movable rod 32, so that the movable rod 32 in the retracted state and the elastic cushion 34 of the movable outer sleeve can be completely received in the box cover 2.

[0042] like Figure 5 、 Figure 6 and Figure 10 As shown: the locking module 35 includes a limiting portion 351, which is coaxially fixed to the end of the fixed rod 31, and a sliding shaft 352 is radially fixed to one side of the limiting portion 351 and is slidably connected to the sliding groove 23; a half gear 353 is also fixed to the end of the limiting portion 351, and the half gear 353 is coaxially arranged with the sliding shaft 352; a limiting seat 354 is fixed to one end of the box cover 2 and is arranged near the insertion openings of the first hole 21 and the second hole 22 to limit the pulled-out backrest 3; the elastic locking element 4 is fixed to one side of the short side of the box body 1 and is located directly below the limiting seat 354.

[0043] In the working state, when the user needs to use the backrest 3, in the process of pulling the backrest 3 out from the first hole 21 and the second hole 22, under the action of the limiting portion 351 set at the proximal end of the backrest 3 and the sliding shaft 352 radially fixed on the side wall of the limiting portion 351, the pulled out backrest 3 will be limited by the limiting seat 354, and the sliding shaft 352 can be freely rotated and adjusted with the limiting seat 354 as the center of the circle, so as to meet the leaning needs of different users.

[0044] like Figure 6 As shown: the elastic locking element 4 includes a mounting seat 41 and a telescopic plate 42 vertically arranged below the mounting seat 41 in a vertical state, and a limit plate 43 is vertically fixed on the telescopic plate 42, which passes through the mounting seat 41 and is arranged toward the upper surface of the mounting seat 41; the extension plate 46 is laterally fixed at the connection between the telescopic plate 42 and the limit plate 43; the guide rod 44 is vertically fixed on the lower surface of the mounting seat 41 and the rod portion of the guide rod 44 passes through the extension plate 46 and is slidably connected to the extension plate 46; the distal end of the guide rod 44 is also coaxially fixed with a flange 47; the spring 45 is coaxially sleeved and installed outside the guide rod 44, one end of the spring 45 is in contact with the lower surface of the extension plate 46, and the other end is in contact with the flange 47.

[0045] In the working state, when the backrest 3 needs to be adjusted to the support angle of the backrest 3 after the user pulls it out from the first hole 21 and the second hole 22, the staff presses the telescopic plate 42, so that the telescopic plate 42 contracts vertically downward while the limiting plate 43 drops synchronously. Then the staff holds the backrest 3 with the other hand, adjusts the backrest 3 to the required support angle and then releases the telescopic plate 42. At this time, the telescopic plate 42 will automatically reset under the elastic force of the spring 45. During the resetting process, the limiting plate 43 will be inserted into the tooth groove of the half gear 353, thereby locking the backrest 3 adjusted to the corresponding angle.

[0046] like Figure 1As shown: hinge parts 12 are fixedly provided at both ends of the short side of the box body 1, and the handle 11 is arranged across the two sets of hinge parts 12 and is hingedly connected to the hinge parts 12 fixed at both ends of the box body 1; telescopic legs 13 are vertically telescopically provided at the four corners of the lower surface of the box body 1 to support the box body 1.

[0047] In working state, the handle 11 is used for the user to grasp, so as to lift the fishing box and move it; the telescopic legs 13 arranged at the four corners of the lower surface of the box body 1 are used to support the box body 1 and each set of telescopic legs 13 can be adjusted independently, so that when the fishing box is used in complex terrain, the box body 1 can still remain in a horizontal state, providing the user with a comfortable fishing experience.

[0048] like Figure 1 As shown, the movable rod 32 is also covered with an elastic cushion 34.

[0049] The material of the elastic cushion 34 is preferably elastic woven cloth. Using elastic woven cloth as a cushion for the user to lean on can not only provide a better support rod for the user, but also, when the backrest 3 is stored, the elastic cushion 34 can be axially compressed to the top of the movable rod 32 by utilizing its own flexibility; the cushion can also be a snap-on fixed cushion.

[0050] like Figure 5 and Figure 10 As shown: the linear reciprocating drive 33 includes a battery 331, which is coaxially fixed in the fixed rod 31 and is arranged near the bottom end of the fixed rod 31; the electric push rod 332 is coaxially fixed in the fixed rod 31 and is located above the battery 331, and the driving end of the electric push rod 332 passes through the top of the fixed rod 31 and is fixedly connected to the movable rod 32; a charging port 333 is also provided on one side of the battery 331 and the charging port 333 is radially passed through the fixed rod 31; the control button 334 is installed on the box cover 2 when embedded to control the action of the electric push rod 332.

[0051] In the working state, when the staff adjusts the backrest 3 to the required angle and locks it, and needs to raise or lower the supporting point of the movable rod 32, the staff operates the control button 334 according to the adjustment requirements, and controls the output shaft of the electric push rod 332 to extend and contact the sliding sleeve of the movable rod 32 installed outside the fixed rod 31 through the control button 334, so that the movable rod 32 slides back and forth along the axis of the fixed rod 31 under the drive of the electric push rod 332, thereby realizing the free adjustment of the supporting point and height of the movable rod 32.

[0052] like Figure 10As shown, an adsorption magnetic ring 25 is coaxially fixedly provided in the first jack 21 and the second jack 22 , respectively. The adsorption magnetic ring 25 is provided at one end away from the insertion openings of the first jack 21 and the second jack 22 .

[0053] The backrest 3 in the non-use state is stored in the first hole 21 and the second hole 22; in order to prevent the backrest 3 from detaching from the first hole 21 and the second hole 22 due to gravity in the non-use state, the fixing rod 31 is adsorbed by the adsorption magnetic ring 25 coaxially fixed in the first hole 21 and the second hole 22, so that the backrest 3 cannot be pulled out from the first hole 21 and the second hole 22 without a large pulling force.

[0054] A fishing box with a movable backrest. This embodiment not only can adjust the support angle and height according to user needs, but also adopts a hidden design, which can retain the box cover area to the greatest extent, provide the user with the largest sitting area, and improve the fishing experience.

[0055] Example 2:

[0056] Compared with Example 1, Figure 10 As shown: the power supply module 5 includes a power supply board 51, which is embedded in the box cover 2 and is arranged near the end away from the insertion port of the first jack 21; the lower surface of the power supply board 51 is also provided with a power supply port corresponding to the charging port 333; the power access socket 52 is provided on the upper surface of the power supply board 51 for connecting to an external power supply, and the sealing cover plate 53 is buckled and arranged outside the power supply board 51.

[0057] In the working state, when the battery 331 needs to be charged, first open the sealing cover 53 and connect the external charging cable to the power access socket 52; at this time, since the backrest 3 is in the storage state, the charging port 333 of the battery 331 stored in the first socket 21 and the second socket 22 will automatically be set to correspond to the power supply port, thereby realizing the charging of the battery 331.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
