[0019] The following is a further detailed description of the specific implementation of the present invention in conjunction with 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.

[0020] The utility model provides a locking mechanism for locking the support leg 50 to the chassis of the vehicle, such as Figure 1 As shown, a locking mechanism of an embodiment includes a mounting assembly 10, a locking assembly 20 and a guide member 40, wherein the locking assembly 20 is fixedly connected to the mounting assembly 10 and locked to the chassis of the vehicle, the mounting assembly 10 is detachably connected to the leg through a fastener 30, and the guide member 40 is fixedly connected to the leg 50. When the fastener 30 is loosened, the mounting assembly 10 can slide with the guide member 40 relative to the leg 50 to adjust the position on the leg 50, and when the fastener 30 is tightened, the mounting assembly 10 and the leg 50 remain relatively fixed. Specifically, the fastener 30 can be a bolt.

[0021] In the locking mechanism and vehicle of the utility model, the mounting assembly 10 can be slidably connected with the guide member 40. After the mounting assembly 10 moves to different positions of the guide member 40, it is fixedly connected to the leg 50 through the fastener 30, and then locked with the chassis of the vehicle through the locking assembly 20, so that the leg 50 is relatively fixedly connected to the chassis of the vehicle as a whole. The locking mechanism in the utility model moves along the first direction on the leg 50 to adjust the installation position, and there is no need to weld multiple installation plates on the leg 50 to match different chassis. The overall structure is simple, the cost is reduced, the appearance is improved, and it can be quickly adjusted to a suitable installation position, which improves work efficiency.

[0022] The first direction in this embodiment is the length direction of the leg. For ease of description and understanding, the first direction is defined as the left-right direction. The right end of the leg is fixedly connected to the frame.

[0023] It should be noted that the outrigger 50 in this embodiment is the rear outrigger on the concrete pump truck. When the pump truck completes the concrete pumping work, in order to prevent the rear outrigger from opening due to not being locked when the concrete pump truck is driving normally on the road, causing damage to people and objects, the opened rear outrigger needs to be retracted and locked to the chassis.

[0024] In this embodiment, Figure 2 As shown, the locking mechanism includes a guide member 40, which is provided with a guide groove 41, which has a length extending in the left-right direction, and at least one end of the guide groove 41 extends to the end surface of the guide member 40, and the guide member 40 is fixedly mounted on the leg 50, and the mounting assembly 10 is slidably connected with the guide member 40 in the left-right direction through the guide groove 41. Specifically, the mounting assembly 10 can quickly determine the required installation position of the leg 50 by moving in the guide groove 41, and when the vehicle chassis is different, the leg 50 can be locked by moving the mounting assembly 10 to a position matching the chassis. This process does not require the installation of multiple mounting parts on the leg 50, resulting in structural redundancy, high cost and poor appearance.

[0025] In this embodiment, Figure 3-4 The mounting assembly 10 includes a mounting plate 11, and the locking assembly 20 is fixedly connected to the mounting plate 11. The guide groove 41 is formed by a bottom wall 42, a first side wall 43 and a second side wall 44 that are oppositely arranged. The first side wall 43 is provided with a plurality of first protrusions 431 protruding toward the second side wall 44. The plurality of first protrusions 431 are spaced apart along the left-right direction, and a first groove 432 is formed between two adjacent first protrusions 431. The mounting plate 11 enters the guide groove 41 from one end of the guide member 40, and the mounting plate 11 is located between the first protrusion 431 and the bottom wall 42 and moves along the left-right direction.

[0026] Specifically, the two sections of the guide groove 41 in this embodiment extend in the left-right direction to the two end surfaces of the guide member 40. The mounting plate 11 enters the guide groove 41 from the left end or the right end of the guide member 40, and the first protrusion 431 makes it difficult for the mounting plate 11 to leave the guide groove 41 during the movement in the guide groove 41, thus playing a certain role of limiting.

[0027] In another preferred embodiment, the guide groove 41 includes a first groove section and a second groove section, that is, the guide groove 41 is a T-shaped groove as a whole. It should be noted that the cross section of the guide groove 41 is T-shaped, and is divided into a first groove section and a second groove section by the cross-sectional direction of the guide groove 41. Among them, the groove width of the first groove section is smaller than the groove width of the second groove section, and the mounting plate 11 enters the second groove section from one end of the guide member 40 and moves in the second groove section along the first direction. The guide groove 41 is set as a T-shaped groove, which plays a certain limiting role on the mounting plate 11 during the movement process, so that the mounting plate 11 is not easy to leave the guide groove 41 during the movement in the left and right directions.

[0028] In this embodiment, the mounting assembly 10 also includes a card plate 12, which has a card protrusion 121 that cooperates with the first groove 432. There are multiple card protrusions 121 and they are distributed at intervals along the first direction. A card groove 122 is formed between two adjacent card protrusions 121. When the fastener 30 is tightened, the card groove 122 cooperates with the first protrusion 431, and the card plate 12 is fixedly installed on the leg together with the mounting plate 11. When the fastener 30 is loosened, the card plate 12 moves in a direction away from the bottom wall 42, so that the mounting plate 11 moves in the guide groove 41.

[0029] After the mounting plate 11 drives the locking assembly 20 to move to a suitable installation position, the mounting plate 11 does not move further, and the clamping plate 12 is placed at the first side wall 43 and connected thereto, that is, the clamping protrusion 121 and the first groove 432 are matched in convex and concave, and the clamping groove 122 and the first protrusion 431 are matched in convex and concave. At this time, the position of the clamping plate 12 is defined, and then the clamping plate 12 and the mounting plate 11 are synchronously fixedly connected to the leg 50 through the fastener 30. The convex and concave matching between the clamping plate 12 and the guide member 40 can make the mounting plate 11 more stable, so that the locking assembly 20 can lock the leg 50 and the chassis of the vehicle more firmly, and the leg 50 is not easy to shake when the vehicle moves.

[0030] When the locking mechanism needs to adjust the installation position, the fastener 30 is loosened, and the card plate 12 is also in a loose state. The card plate 12 is moved a certain distance away from the bottom wall 42, so that the snap-on protrusion 121 leaves the first groove 432 or the second groove 442, and the first protrusion 431 or the second protrusion 441 also leaves the snap-on groove 122. At this time, the mounting plate 11 is moved to a suitable installation position, and then the fastener 30 is tightened to synchronously fix the card plate 12 to the mounting plate 11. The card plate 12 and the guide member 40 are in a convex-concave matching connection state.

[0031] In another preferred embodiment, there are two card boards 12, and the second side wall 44 is provided with a plurality of second protrusions 441 in the direction toward the first side wall 43, and the plurality of second protrusions 441 are spaced apart along the first direction, and a second groove 442 is formed between two adjacent second protrusions 441, and the clamping protrusion 121 and the clamping groove 122 of one card board 12 are respectively matched and connected with the second groove 442 and the second protrusion 441, and the two card boards 12 are fixedly mounted on the supporting leg with the mounting plate 11 through the fasteners 30. The two card boards 12 are fixedly mounted on the supporting leg 50 with the mounting plate 11 through the fasteners 30. When the mounting plate 11 moves to a specific mounting position, by providing a clamping plate 12 at both sections of the mounting plate 11 close to the first side wall 43 and the second side wall 44, and the clamping plate 12 is respectively connected with the guide member 40, the mounting plate 11 can be more stably mounted on the support leg 50. At the same time, after the locking assembly 20 locks the support leg 50 to the chassis of the vehicle, the support leg 50 is not easy to shake during the movement of the vehicle, and is locked more firmly.

[0032] In this embodiment, the clamping plate 12 is provided with a mounting hole 123 , and the mounting hole 123 has a length extending along the first direction. The fastener 30 is installed in cooperation with the mounting hole 123 to fix the clamping plate 12 and the mounting plate 11 to the supporting leg 50 .

[0033] Specifically, the mounting hole 123 is a long waist-shaped hole. The waist-shaped hole can provide stable positioning and fixing functions, so that the clamping plate 12 and the mounting plate 11 can be better fixed to the supporting leg 50 through the fastener 30.

[0034] In this embodiment, the locking assembly 20 includes a leg lock 21 and a lock buckle 22. The leg lock 21 is detachably connected to the lock buckle 22, and the lock buckle 22 is fixedly connected to the chassis of the vehicle.

[0035] Specifically, the leg lock 21 includes a lock core 211, and the lock buckle 22 is detachably connected to the leg lock 21 through the lock core 211. The lock buckle 22 is first installed at a certain position, that is, the lock buckle 22 is fixedly installed on the chassis of the vehicle, and the mounting plate 11 drives the leg lock 21 to move in the left and right directions, moves close to the lock buckle 22, and enables the lock buckle 22 to be relatively fixedly connected to the leg lock 21 through the lock core 211.

[0036] When installing the locking mechanism, the mounting plate 11 is inserted into the guide groove 41 from one end of the guide member 40, and the appropriate position of the leg lock 21 is determined according to the position of the lock buckle 22. After the mounting plate 11 drives the leg lock 21 to move to the determined installation position in the guide groove 41, the two clamping plates 12 are installed on both sides of the leg lock 21. The clamping plates 12 and the guide member 40 are connected with each other in a convex-concave manner, that is, the toothed structure on the clamping plates 12 is engaged with the toothed structure on the guide member 40. After determining the position of the clamping plates 12, the fasteners 30 are used to fix the clamping plates 12 on the leg 50. At this time, the leg lock 21 and the mounting plate 11 are fixedly installed on the leg 50 together, and then the lock buckle 22 is fixedly connected to the leg lock 21 to complete the locking of the leg 50.

[0037] The utility model also provides a vehicle, including a chassis, a leg and the locking mechanism as described above, wherein the locking assembly 20 is locked to the chassis, and the mounting assembly 10 is detachably connected to the leg through a fastener 30. The vehicle in this embodiment can be a concrete pump truck, and of course can also be other engineering machinery such as a fire truck, an aerial work vehicle, etc.
