DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the embodiments of the present application.

[0030] As Figure 1 , Figure 2As shown in the first aspect, the present application provides a support leg, comprising: a main support leg 2, a secondary support leg 4, a mounting frame 1, a cylinder 3 and a locking mechanism;

[0031] The main support leg 2 is rotationally connected with the mounting frame 1, and the main support leg 2 has a support position and a storage position; when the main support leg 2 is in the support position, the main support leg 2 is perpendicular to the mounting frame 1; when the main support leg 2 is in the storage position, the main support leg 2 is parallel to the mounting frame 1;

[0032] The secondary support leg 4 is slidably connected with the main support leg 2 in a first direction, and the first direction is the extension direction of the main support leg 2; the cylinder 3 is rotationally arranged on the mounting frame 1, and the power end of the cylinder 3 is rotationally connected with the secondary support leg 4 through a cylinder pin shaft 31, so as to drive the secondary support leg 4 to slide relative to the main support leg 2 in the first direction, and convert the main support leg 2 between the support position and the storage position;

[0033] The locking mechanism is movably arranged between the secondary support leg 4 and the main support leg 2, and is used for locking the position of the secondary support leg 4 relative to the main support leg 2 when the main support leg 2 is in the support position.

[0034] The present application is provided with a cylinder 3 for pushing the secondary support leg 4, when the secondary support leg 4 needs to be stretched out, the output end of the cylinder 3 can push the secondary support leg 4 to slide relative to the main support leg 2, so that the secondary support leg 4 can be extended relative to the main support leg 2, and finally the secondary support leg 4 is perpendicular to the mounting frame 1, in the above process, the support process of the secondary support leg 4 is completed by the pushing of the cylinder 3, so that the main support leg 2 and the secondary support leg 4 can quickly slide, and the stretching process does not need too much manual operation of the staff, which simplifies the time of leg stretching and the process of stretching.

[0035] In addition, the present application is additionally provided with a locking mechanism for locking the main support leg 2 and the secondary support leg 4, the secondary support leg 4 is used for locking the position of the secondary support leg 4 to the main support leg 2 when it is in the support position, after the cylinder 3 reaches the predetermined position, the cylinder 3 will play a certain supporting role to the secondary support leg 4, and at this time the locking mechanism will play a secondary locking role to the secondary support leg 4, which improves the stability of the main support leg 2 and the secondary support leg 4 after installation.

[0036] In one possible implementation manner, as Figure 2 As shown, the main support leg 2 is rotationally connected with the mounting frame 1 through a rotating shaft 21, when the secondary support leg 4 is switched from the storage position to the stretching position, the secondary support leg 4 rotates around the rotating shaft 21 under the action of the rotating shaft 21, which to some extent simplifies the stretching process between the main support leg 2 and the secondary support leg 4.

[0037] Optionally, the locking mechanism comprises a driving wheel 51, a ratchet 54 and a ratchet pin 55.

[0038] The driving wheel 51 is rotatably installed on the auxiliary support leg 4 by a first sliding pin 5.

[0039] One end of the ratchet 54 is rotatably installed on the edge of the driving wheel 51 by the ratchet pin 55, and the other end of the ratchet 54 has a toothed portion; the main support leg 2 is provided with a clamping groove 23 for clamping the toothed portion.

[0040] In one possible implementation, as shown in Figure 3 the locking mechanism comprises a driving wheel 51, a ratchet 54 and a ratchet pin 55.

[0041] The driving wheel 51 is rotatably installed on the auxiliary support leg 4 by a first sliding pin 5.

[0042] One end of the ratchet 54 is rotatably installed on the edge of the driving wheel 51 by the ratchet pin 55, and the other end of the ratchet 54 has a toothed portion; the main support leg 2 is provided with a clamping groove 23 for clamping the toothed portion.

[0043] In one possible implementation, as shown in Figure 4 the driving wheel 51 is rotated in the direction of the arrow in the drawing, and at the same time drives the ratchet 54 to rotate; at this time, the ratchet 54 does not contact the clamping groove 23; when the support blocking arm 52 contacts and abuts against the cylinder pin 31, the ratchet 54 extends into the clamping groove 23 and is clamped with the clamping groove 23, thereby achieving the locking between the auxiliary support leg 4 and the main support leg 2.

[0044] Optionally, the support leg further comprises an elastic member 10, one end of the elastic member 10 is connected to the auxiliary support leg 4, and the other end of the elastic member 10 is connected to the edge of the driving wheel 51.

[0045] In one possible implementation, as shown in Figure 4The support leg further comprises an elastic member 10, one end of the elastic member 10 is connected to the auxiliary support leg 4, and the other end of the elastic member 10 is connected to the edge of the driving rotary wheel 51. In the above structure, the elastic member 10 is provided for connection with the auxiliary support leg 4. During use, the elastic member 10 has a certain elastic deformation. When the auxiliary support leg 4 is switched between the stretching station and the storage station, the driving rotary wheel 51 rotates and drives the ratchet 54 to be separated from the clamping groove 23 under the action of the elastic member 10, so that the auxiliary support leg 4 is stored in the main support leg 2 without interference.

[0046] In one possible implementation manner, Figure 3 The support leg further comprises a handle 7 connected with the first sliding pin 5 for driving the first sliding pin 5 to rotate. In the above structure, the handle 7 is additionally provided, and a worker can drive the driving rotary wheel 51 through the handle 7 during use. This process is simple and effective and convenient to operate.

[0047] In one possible implementation manner, Figure 4 The support leg further comprises an elastic member 10 and a torsion spring pin 11 arranged at both ends of the elastic member 10. One end of the elastic member 10 is arranged on the main support leg 2 through the torsion spring pin 11, and the other end of the elastic member 10 is arranged on the driving rotary wheel 51 through the torsion spring pin 11. During switching of the auxiliary support leg 4 from the storage station to the stretching station, the driving rotary wheel 51 pulls the elastic member 10 to change the shape of the elastic member 10, so that the elastic member 10 has an elastic deformation force to restore the shape of the elastic member 10. During the process of recovering the auxiliary support leg 4 by the cylinder 3, the auxiliary support leg 4 moves towards the position of the main support leg 2. At this time, only the handle 7 needs to be manually rotated to drive the driving rotary wheel 51 to rotate, so that the ratchet 54 no longer interferes with the clamping groove 23, and the elastic member 10 drives the driving rotary wheel 51 to rotate, facilitating the contraction of the auxiliary support leg 4.

[0048] In one possible implementation manner, Figure 3 The edge of the driving rotary wheel 51 is further provided with a folding blocking arm 53. When the auxiliary support leg 4 is in the storage station, the free end of the folding blocking arm 53 abuts against the cylinder pin shaft 31. In the above structure, the folding blocking arm 53 is integrally formed with the driving rotary wheel 51, which can limit the maximum rotation angle of the driving rotary wheel 51 to the greatest extent when the auxiliary support leg 4 is in the storage station, thereby avoiding the problem of excessive rotation of the driving rotary wheel 51.

[0049] In one possible implementation manner, Figure 4As shown in the figure, the edge of the driving wheel 51 is also provided with a support stop arm 52, when the auxiliary support leg 4 is in the supporting position, the free end of the support stop arm 52 is in abutment with the cylinder pin shaft 31, in the above structure, the application increases the support stop arm 52 on the driving wheel 51, so that the support stop arm 52 can limit the maximum rotation distance of the driving wheel 51 during rotation, so that the worker only needs to rotate the handle 7 by about 80° when rotating the handle 7, and the locking process of the ratchet 54 to the auxiliary support leg 4 can be realized, which is simple and effective.

[0050] In one possible implementation manner, the auxiliary support leg 4 is connected to the main support leg 2 in a sliding manner. Figure 1 As shown in the figure, the locking mechanism 6 is fixed to the support, and the locking mechanism 6 has a support pin slot 61.

[0051] The auxiliary support leg 4 is provided with a support pin 9; when the main support leg 2 is in the storage position, the support pin 9 is clamped with the support pin slot 61, in the above structure, the application increases the support pin 9 for the auxiliary support leg 4 in the storage position, when the auxiliary support leg 4 is in the storage position, the support pin 9 is inserted into the inside of the support pin slot 61 and is limited by the support pin slot 61, so that the auxiliary support leg 4 will not fall off the mounting frame 1 when it is in the storage position, in addition to the contraction of the cylinder 3 to complete the storage process of the auxiliary support leg 4, the locking mechanism 6 can lock the auxiliary support leg 4 again, which improves the stability of the overall structure of the application.

[0052] In one possible implementation manner, the auxiliary support leg 4 is connected to the main support leg 2 in a sliding manner. Figure 1 As shown in the figure, the support leg further includes a support foot 8, which is arranged at one end of the auxiliary support leg 4 away from the main support leg 2, in the above structure, the application increases the support foot 8, and the plane where the support foot 8 is located is perpendicular to the auxiliary support leg 4, when the auxiliary support leg 4 is in the stretched position, the support foot 8 can obtain a larger contact area with the ground, which ensures that the support leg will not shake.

[0053] In one possible implementation manner, the auxiliary support leg 4 is connected to the main support leg 2 in a sliding manner. Figure 1 As shown in the figure, the auxiliary support leg 4 is provided with an auxiliary support leg sliding groove 42, the main support leg 2 is provided with a second sliding pin 41, and the main support leg 2 is provided with a sliding channel 22 for accommodating the first sliding pin 5, the auxiliary support leg sliding groove 42 is in sliding connection with the second sliding pin 41, in the above structure, the application connects the auxiliary support leg 4 and the main support leg 2 in a sliding manner, which can improve the speed of unfolding between the main support leg 2 and the auxiliary support leg 4.

[0054] In one possible implementation manner, the auxiliary support leg 4 is connected to the main support leg 2 in a sliding manner. Figure 5In the second aspect, the application further provides a vehicle, comprising a vehicle body 12 and a support leg as any one of the above, wherein the mounting frame 1 in the support leg is mounted on the vehicle body 12, and in the above structure, the main support leg 2 and the auxiliary support leg 4 in the application are both mounted at the chassis position of the vehicle body 12, and during the operation of the vehicle body 12, the main support leg 2 and the auxiliary support leg 4 do not protrude out of the side of the vehicle body 12, thereby improving the safety during the operation of the vehicle body 12.
