[0002] In outdoor activities such as fishing, camping, etc., luggage or articles often need to be carried, and trailer tools are often used in the carrying process. The trailer is widely used in carrying things due to its convenient pushing and time-saving and labor-saving characteristics. The existing outdoor tool car needs to be operated manually to fold the frame of the tool car after releasing the locked structure, which is inconvenient to operate. UTILITARY MODEL CONTENT

[0004] The present application provides a portable outdoor tool car, which includes two mounting frames, a flexible member, an adjusting mechanism and an elastic member. The two mounting frames are arranged in overlap along a first direction, and the two mounting frames have a closed position and an unfolded position. The distance between the two mounting frames in the first direction in the unfolded position is greater than that in the closed position. The two ends of the flexible member are connected to the two mounting frames respectively. The flexible member is provided around the circumferential side of the mounting frame.

The two ends of the elastic member are connected to the two mounting frames respectively, and the elastic member is used to provide an elastic force to the two mounting frames to guide the two mounting frames to move to the closed position.

[0005] Specifically, when unfolding the portable outdoor tool car, one of the two mounting frames is driven by the adjusting mechanism to move relative to the other along the first direction, so that the distance between the two mounting frames in the first direction becomes larger. On the one hand, the elastic member is elongated, so that the elastic force provided by the elastic member to the two mounting frames becomes larger.

[0006] When the portable outdoor tool cart is folded, the adjusting mechanism no longer fixes the two mounting frames, at this time, the elastic member is retracted to drive the two mounting frames to move in the first direction to make the two mounting frames in the closed position, thereby making the portable outdoor tool cart fold.

[0007] In the above technical solution, the elastic member drives the two mounting frames to move to the closed position when the adjusting mechanism does not fix the two mounting frames, so that the portable outdoor tool cart can be automatically folded when the structure is released.

[0026] In outdoor activities such as fishing, camping, etc., it is often necessary to carry luggage or articles, etc. during the carrying process, and trailer tools are often used. The trailer is widely used in carrying things because of its convenient pushing and time-saving and labor-saving characteristics. The existing outdoor tool car needs to be operated by the operator to manually fold the frame of the tool car after releasing the locked structure, which is relatively inconvenient to operate.

[0027] In order to solve the above technical problems, with reference to Figures 1-4The portable outdoor tool vehicle provided by the embodiment of the application comprises two mounting frames 10, flexible members, an adjusting mechanism 20 and elastic members 30. The two mounting frames 10 are arranged in overlap along a first direction X, and the two mounting frames 10 have a closed position and an unfolded position. In the unfolded position, the distance between the two mounting frames 10 along the first direction X is greater than that in the closed position. The two ends of the flexible members are connected with the two mounting frames 10 respectively. The flexible members are arranged around the circumferential side of the mounting frames 10, and the plurality of flexible members and the two mounting frames 10 form a containing cavity with an opening on one side. The two ends of the adjusting mechanism 20 are connected with the two mounting frames 10 respectively, so as to drive one of the two mounting frames 10 to move relative to the other along the first direction X, and to releasably fix the two mounting frames 10 in the unfolded position. The two ends of the elastic members 30 are connected with the two mounting frames 10 respectively, and the elastic members 30 are used to provide elastic force to the two mounting frames 10 to guide the two mounting frames 10 to move towards the closed position.

[0028] The first direction X is

[0029] The flexible members (not shown in the figure) can be canvas, which is light in weight and has certain toughness.

[0030] The elastic members 30 can be elastic ropes or tensile springs.

[0031] Specifically, when unfolding the portable outdoor tool vehicle, the adjusting mechanism 20 is used to drive one of the two mounting frames 10 to move relative to the other along the first direction X, so that the distance between the two mounting frames 10 along the first direction X is increased. On the one hand, the elastic members 30 are elongated, so that the elastic force provided by the elastic members 30 to the two mounting frames 10 is increased. On the other hand, the two ends of the flexible members are moved away from each other, so that the flexible members are straightened, so that the flexible members can carry luggage or articles, so that the portable outdoor tool vehicle is in the unfolded position, and the two mounting frames 10 are fixed in the unfolded position by the adjusting mechanism 20.

[0032] When folding the portable outdoor tool vehicle, the adjusting mechanism 20 is no longer used to fix the two mounting frames 10. At this time, the elastic members 30 are contracted to drive the two mounting frames 10 to move along the first direction X to make the two mounting frames 10 in the closed position, so that the portable outdoor tool vehicle is folded.

[0033] In the technical solution, the elastic members 30 are used to drive the two mounting frames 10 to move towards the closed position when the adjusting mechanism 20 is no longer used to fix the two mounting frames 10, so that the portable outdoor tool vehicle can be automatically folded when the structure is released, which is convenient for the operator to operate.

[0034] According to some embodiments of the present application, the adjusting mechanism 20 comprises two groups of first connecting rods 21 and a driving assembly 22; the two groups of first connecting rods 21 are respectively arranged in the two mounting frames 10, each group of first connecting rods 21 comprises two first connecting rods 21, the first connecting rods 21 are oppositely arranged with first ends 211 and second ends 212, the first ends 211 of the first connecting rods 21 in each group are rotationally arranged in the same mounting frame 10 and arranged along the gravity direction Z, the two first connecting rods 21 in each group are arranged alternately, the second end 212 of any first connecting rod 21 in any group is rotationally connected with the second end 212 of another first connecting rod 21 in another group, and the first direction X is perpendicular to the gravity direction Z; the driving assembly 22 is used to drive the two second ends 212 of any group of first connecting rods 21 to move towards each other, so as to drive the two groups of first connecting rods 21 to drive the two mounting frames 10 to move towards the unfolded position.

[0035] When the elastic member 30 is contracted to drive the two mounting frames 10 to move towards each other along the first direction X,

[0036] Exemplarily, the first connecting rods 21 can be made of metal materials.

[0037] Specifically, when the portable outdoor tool cart needs to be unfolded, the driving assembly 22 is driven to drive the two second ends 212 of the first connecting rods 21 in the same group to rotate towards each other, so as to drive the two second ends 212 of the first connecting rods 21 in the same group to rotate away from the mounting frame 10 on which the group of first connecting rods 21 is arranged, and at the same time, drive the two second ends 212 of the first connecting rods 21 in the other group to rotate away from the mounting frame 10 on which the other group of first connecting rods 21 is arranged, so as to drive the two mounting frames 10 to move away from each other along the first direction X. When the portable outdoor tool cart is folded, the relative positions of the two second ends 212 of the first connecting rods 21 in the same group are no longer limited by the driving assembly 22, and when the elastic member 30 is contracted to drive the two mounting frames 10 to move towards each other along the first direction X, the two second ends 212 of the first connecting rods 21 in the same group rotate away from each other, so as to drive the two second ends 212 of the first connecting rods 21 in the same group to rotate towards the mounting frame 10 on which the group of first connecting rods 21 is arranged, and at the same time, drive the two second ends 212 of the first connecting rods 21 in the other group to rotate towards the mounting frame 10 on which the other group of first connecting rods 21 is arranged.

[0038] According to some embodiments of the present application, the driving assembly 22 comprises a rotating wheel 221 and a connecting rope 222; the rotating wheel 221 is rotationally arranged at the second end 212 of any first connecting rod 21 in any group of first connecting rods 21; one end of the connecting rope 222 is connected with the second end 212 of another first connecting rod 21 in any group of first connecting rods 21, and the other end is wound around the outer periphery of the rotating wheel 221, and the rotating wheel 221 rotates to wind or release the connecting rope 222.

[0039] In some embodiments, the handle 2211 is arranged on the rotating wheel 221 to facilitate the operator to rotate the rotating wheel 221 through the handle 2211.

[0040] In some embodiments, another first connecting rod 21 in any group of the first connecting rods 21 is provided with a mounting shaft 2221, the axis of the mounting shaft 2221 is parallel to the second direction Y, and one end of the connecting rope 222 is wound and fixed on the outer periphery of the mounting shaft 2221.

[0041] Specifically, the rotating wheel 221 rotates to wind the connecting rope 222, so that the distance between the other end of the connecting rope 222 and the rotating wheel 221 is reduced, thereby driving the two second ends 212 of the first connecting rods 21 in the same group to rotate towards each other.

[0042] According to some embodiments of the present application, the driving assembly 22 further comprises a ratchet wheel 223 and a pawl 224; the ratchet wheel 223 is coaxially fixed on the rotating wheel 221; the pawl 224 is arranged on the second end 212 of any first connecting rod 21 in any group of the first connecting rods 21 and cooperates with the ratchet wheel 223, and the pawl 224 is used to limit the rotation of the ratchet wheel 223 and the rotating wheel 221 in the direction of releasing the connecting rope 222.

[0043] In some embodiments, the driving assembly 22 further comprises a housing 225 and a spring; the housing 225 is installed on the second end 212, and the housing 225 has a receiving cavity; one end of the rotating wheel 221 passes through the receiving cavity coaxially and is rotatably arranged on the second end 212; the other end of the rotating wheel 221 passes through the housing 225 and is located outside the housing 225 to wind the connecting rope 222; the ratchet wheel 223 is sleeved on the end of the rotating wheel 221 located in the receiving cavity; the middle part of the pawl 224 is fixed relative to the rotating wheel 221; one end of the pawl 224 abuts against the ratchet wheel 223; the other end of the pawl 224 passes through the inner wall of the receiving cavity and is located outside the housing 225; one end of the spring is fixed on the inner wall of the receiving cavity, and the other end of the spring is installed on the side of the pawl 224 away from the ratchet wheel 223. Specifically, an external force is applied to the end of the pawl 224 located outside the housing 225 to drive the end of the pawl 224 located outside the housing 225 to rotate, thereby driving the end of the pawl 224 located in the receiving cavity to rotate, so that the end of the pawl 224 located in the receiving cavity no longer abuts against the ratchet wheel 223, thereby the pawl 224 no longer limits the rotation of the ratchet wheel 223 and the rotating wheel 221 in the direction of releasing the connecting rope 222; when the external force is no longer applied, the spring resets to drive the end of the pawl 224 located in the receiving cavity to reset, so that the pawl 224 abuts against the ratchet wheel 223 again. In turn, the pawl 224 limits the rotation of the ratchet wheel 223 and the rotating wheel 221 in the direction of releasing the connecting rope 222.

[0045] Exemplarily, the second connecting rod 226 is made of metal material.

[0046] In the technical solution, the second connecting rod 226 is arranged to assist the rotation of the first connecting rod 21, so that the rotation of the first connecting rod 21 is more stable.
