Description

Technical Field

[0001] This utility model relates to an auxiliary support leg, specifically an auxiliary support leg with freely adjustable angle. Background Technology

[0002] The auxiliary support legs of wheeled lathes / beds have functions such as retraction, assisted gliding, and support. However, current designs can only support the auxiliary wheels in a fixed and inconvenient direction, and cannot freely adapt the angle of the auxiliary wheels as the vehicle turns. When the vehicle turns, the auxiliary wheels cannot provide steering function and can only passively follow the wheels, being dragged along. The turning radius is relatively large, which is quite inconvenient. Utility Model Content

[0003] To address the shortcomings of the existing technology, this invention provides an auxiliary support leg with freely adjustable angle. This invention is equipped with a steering mechanism, which allows for free adjustment of the auxiliary wheel angle, resulting in better self-adaptation, a smaller turning radius, and greater safety and convenience. On uneven ground, it can automatically avoid bumps.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: an auxiliary support leg with freely adjustable angle, comprising a connecting rod, a steering mechanism, an adapter, and a support frame. The connecting rod is assembled with the steering mechanism. The first side of the adapter is fixedly connected to the steering mechanism, the second side is fixedly installed with the support frame, and the third side is used to connect to an auxiliary wheel. The support frame is provided with a steering angle limiting block for limiting the rotation angle of the adapter.

[0005] The adapter has a connection hole, the steering mechanism is fixed to the connection hole, a boss is provided at the connection hole, the boss is embedded in the hole of the connecting rod, and the upper part of the steering angle limiting block is higher than the surface of the connecting rod to achieve the stopping function.

[0006] The steering angle limiting block is fitted with an auxiliary plane, the steering angle limiting block is higher than the auxiliary plane, the surface of the adapter is a first plane, and the auxiliary plane is flush with the first plane.

[0007] The other end of the connecting rod is provided with a telescopic connector, which is installed on the connecting rod to the left or right to adapt to installation on the left or right sides.

[0008] The adapter has a support frame mounting part and a support frame limiting part one on the second side. The support frame also has a support frame limiting part two. The end of the support frame is fixed to the support frame mounting part and is limited by the support frame limiting part one and the support frame limiting part two.

[0009] The support frame mounting part adopts two support frame mounting grooves on two opposite sides of the second side of the adapter. The first support frame limiting part adopts baffle one and baffle two on both sides of the support frame mounting groove. The end of the support frame is provided with two mounting plates. The second support frame limiting part is located at the corner of the mounting plate. The two mounting plates are fixed to the support frame mounting groove with bolts, and the mounting plates are limited by baffle one, baffle two and the corner.

[0010] It also includes a plate for mounting auxiliary wheels. The third side of the adapter is provided with a plate mounting part and a shock-absorbing angle limiting part. The plate is hinged to the plate mounting part and limited by the shock-absorbing angle limiting part.

[0011] The insert plate mounting part adopts two opposite side plate mounting slots on the third side of the adapter. The shock absorption angle limiting part adopts a baffle three on the side wall of the insert plate mounting slot. The insert plate is fixed to the insert plate mounting slot with bolts and is limited by the baffle three.

[0012] The insert plate is equipped with a shock-absorbing component, which includes a spring and a guide rod. The first end of the guide rod is provided with an arc-shaped head. The adapter is provided with a movable hole. The arc-shaped head is located in the movable hole and is hinged by a bolt.

[0013] It also includes a suspended basket, which is hinged to the insert plate, and the second end of the guide rod passes through the through hole of the suspended basket and is fastened with a nut.

[0014] In summary, this utility model achieves the following technical effects:

[0037] Example:

[0038] Figure 1 It is an adjustable auxiliary support leg. Figure 2 yes Figure 1 The cross-sectional schematic diagram includes a connecting rod 3, a steering mechanism 2, an adapter 4, and a support frame 6. The connecting rod 3 is assembled with the steering mechanism 2. The first side of the adapter 4 is fixedly connected to the steering mechanism 2, the second side is fixedly installed with the support frame 6, and the third side is used to connect the auxiliary wheel 9. The support frame 6 is provided with a steering angle limiting block 604 for limiting the rotation angle of the adapter 4.

[0039] This invention features a steering mechanism at the front end of the adapter. The steering mechanism can drive the adapter to rotate to change the travel angle of the auxiliary wheel. A steering angle limit block is also provided to limit the rotation angle to within ±X degrees, such as ±15°, to better match the travel direction of the wheeled lathe / bed.

[0040] The steering mechanism can be a bearing, allowing a rotating connection between the adapter and the connecting rod, or it can be a small motor.

[0041] When a car turns, the wheels have a steering function, but the auxiliary wheels are usually dragged along to turn. This invention gives the auxiliary wheels a free steering angle, so that they can turn automatically in coordination with the wheels when the car turns, instead of being dragged along to turn.

[0042] Figure 3 yes Figure 2 The first enlarged partial schematic diagram shows that the adapter 4 has a connection hole 410, the drive end of the steering mechanism 2 (e.g., the drive shaft of the motor) is fixed to the connection hole 410, a boss 412 is provided at the connection hole 410, the boss 412 is embedded in the hole of the connecting rod 3, and the upper part of the steering angle limiting block 604 is higher than the surface of the connecting rod 3 to achieve the stopping function.

[0043] The fixed end of the steering mechanism 2 is located inside the connecting rod 3, and the driving end extends outward and is fixed in the connecting hole 410. The connecting rod 3 is fixed on the wheel lathe / machine, so that when the steering mechanism 2 is working, it can directly drive the adapter 4 to rotate, thereby driving the auxiliary wheel to rotate. The outer diameter of the boss 412 is smaller than the inner diameter of the hole in the connecting rod 3 to avoid jamming and friction.

[0044] Combination Figure 3 and Figure 4 , Figure 4 This is a schematic diagram of a steering angle limiting block. The steering angle limiting block 604 is fitted with an auxiliary plane 605. The steering angle limiting block 604 is higher than the auxiliary plane 605. The surface of the adapter 4 is the first plane 401. The auxiliary plane 605 is flush with the first plane 401.

[0045] There is an auxiliary plane 605 between the steering angle limiting block 604 and the first plane 401. When the adapter 4 rotates, the space generated by this auxiliary plane can provide a certain rotation space.

[0046] This utility model sets two steering angle limiting blocks 604 on the support frame, respectively on both sides of the adapter 4, to achieve stopping and limiting on both sides, which is more effective.

[0047] Figure 5 yes Figure 1 The exploded diagram shows that the other end of the connecting rod 3 is provided with a telescopic connector 1, which is installed on the connecting rod 3 to the left or right to adapt to the installation on the left and right sides.

[0048] Specifically, the connecting rod 3 has multiple holes 301 and the connector 1 has multiple holes 103. Holes 301 and 103 are installed with bolts, which can adjust the amount of extension and the length, and are suitable for wheels of different heights.

[0049] The connector 1 includes a rod 102 and a head 101. The head 101 is cylindrical, and its side is integrally formed with the rod 102. The bottom surface of the head 101 is provided with a fitting block 10 for connecting to a lathe / machine. The rod 102 is a cuboid structure and is symmetrical on both sides. By taking the rod 102 out of the connecting rod 3 and reinstalling it in a different direction, it can be matched for installation on the left and right sides. This has the advantages of reducing molds, reducing processes, and reducing costs for production and processing. It is also universal for both sides and is relatively convenient for maintenance and replacement.

[0050] The connecting rod 3 is a sleeve structure with a hole inside that matches the rod 102. It also has a mounting hole at the bottom for mounting the steering mechanism 2. The drive end of the steering mechanism 2 extends out and connects to the adapter 4.

[0051] Figure 6 This is a schematic diagram of an adapter. The adapter has a herringbone structure, with the three ends of the herringbone being the first side, the second side, and the third side. The first side is the first plane 401, which is used to connect with the connecting rod. The second side is used to connect the support frame 6, and the third side is used to connect the insert plate 7.

[0052] The second side of the adapter 4 is provided with a support frame mounting part and a support frame limiting part one. The support frame 6 is also provided with a support frame limiting part two. The end of the support frame 6 is fixed to the support frame mounting part and is limited by the support frame limiting part one and the support frame limiting part two.

[0053] Specifically, the support frame mounting part adopts two opposite support frame mounting grooves 405 located on the second side of the adapter 4. The first support frame limiting part adopts baffle 406 and baffle 407 located on both sides of the support frame mounting groove 405. The end of the support frame 6 is provided with two mounting plates 601. The second support frame limiting part adopts a corner 603 located on the mounting plate 601. The two mounting plates 601 are fixed to the support frame mounting groove 405 with bolts, and the mounting plates 601 are limited by baffle 406, baffle 407 and corner 603.

[0054] Figure 7 This is a schematic diagram of the connection between the adapter and the support frame. The two mounting plates 601 of the support frame are inserted into the two support frame mounting slots 405. The mounting plates 601 are blocked and limited by the first baffle 406, the second baffle 407 and the corner 603. The connection can be fixed by the third hole 408, the fourth hole 602 and a bolt. No multiple bolts are needed. The rigid connection itself can maintain stability with only one bolt.

[0055] like Figure 5 As shown, it also includes a plate 7 for mounting the auxiliary wheel 9. The adapter 4 has a plate mounting part and a shock-absorbing angle limiting part on its third side. The plate 7 is hinged to the plate mounting part and limited by the shock-absorbing angle limiting part.

[0056] Specifically, the insert plate mounting part adopts two opposite side plate mounting grooves 402 located on the third side of the adapter 4, and the shock absorption angle limiting part adopts a baffle 3 403 located on the side wall of the insert plate mounting groove 402. The insert plate 7 is fixed to the insert plate mounting groove 402 with bolts and is limited by the baffle 3 403.

[0057] The insert mounting slot 402 is arc-shaped, with a larger and arc-shaped entrance. When connected to the insert plate, it can limit the vibration angle of the insert plate. That is, when the insert plate swings during vibration, the swing space of the insert plate is confined within the arc-shaped insert mounting slot 402. Figure 1 This can be seen from the text.

[0058] like Figure 5 As shown, the insert plate 7 is provided with a shock-absorbing component 5, which includes a spring 501 and a guide rod 502. The first end of the guide rod 502 is provided with an arc-shaped head 503. The adapter 4 is provided with a movable hole 411. The arc-shaped head 503 is located in the movable hole 411 and is hinged by a bolt. The movable hole 411 has a structure that is larger on the outside and smaller on the inside, so that the guide rod 502 can rotate around the bolt as an axis.

[0059] Figure 8 yes Figure 2 The second enlarged partial schematic diagram shows that the arc-shaped head 503 is engaged with the movable hole 411. The fifth hole 504 of the arc-shaped head 503 is connected to the sixth hole 409 of the adapter 4 by a pin. The arc-shaped head 503 can swing around the pin. The movable hole 411 provides the space for swinging, which can freely adapt to the undulation of the ground and is suitable for uneven ground, thus improving the shock absorption effect.

[0060] like Figure 5 As shown, it also includes a suspended platform 8, which is hinged to the insert plate 7. The second end of the guide rod 502 passes through the through hole of the suspended platform 8 and is fastened with a nut. The suspended platform 8 can also freely adapt to the undulations of the ground, and can move freely to adapt to different elastic force requirements when the spring stroke needs to be changed.

[0062] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
