[0028] Figures 1-7 This application illustrates an embodiment of a bracket for maintaining a vehicle support leg, including a fixed frame 1 and a movable frame 2. The movable frame 2 is mounted on the fixed frame 1 and can move vertically relative to the fixed frame 1. A support base 3 is provided at the bottom of the movable frame 2 to support the support leg. A locking component 4 is provided directly above the support base 3 to enclose the outer wall of the support leg and restrict the degree of freedom of the upper part of the support leg.

[0029] In this application, the lower end of the vehicle support leg is placed on the support base 3, and the upper part of the support leg is limited by the locking component 4 to prevent the support leg from moving. This ensures the safety of the support leg when it moves. After the fixing frame 1 is moved to the installation position of the support leg, the support leg can be moved to the appropriate installation position by the vertical movement of the moving frame 2, thereby improving the convenience of installing the support leg.

[0030] In some embodiments, the fixing frame 1 includes a first longitudinal bar 11 and a second longitudinal bar 12 arranged longitudinally. A first transverse bar 13 is connected between the end of the first longitudinal bar 11 and the end of the second longitudinal bar 12. A second transverse bar 14 is arranged inside the first transverse bar 13. The two ends of the second transverse bar 14 are respectively connected to the first longitudinal bar 11 and the second longitudinal bar 12. A first vertical bar 15 and a second vertical bar 16 are respectively arranged on both sides of the second transverse bar 14. The first vertical bar 15 and the second vertical bar 16 are connected to the movable frame 2. This ensures the stability of the fixing frame 1.

[0031] In some embodiments, casters 17 are provided at both ends of the first vertical bar 11 and the second vertical bar 12. This facilitates the movement of the mounting bracket 1. A push rod 18 extends from the middle of the first vertical bar 15 and the second vertical bar 16 toward the upper end face of the first horizontal bar 13. This facilitates gripping the push rod 18 to push the mounting bracket 1 to move, improving the ease of moving the mounting bracket 1.

[0032] The vertical movement of the movable frame 2 relative to the fixed frame 1 can be achieved by a combination of a motor and a threaded rod and a sleeve, or by a combination of a motor and a worm gear.

[0033] In some embodiments, a central crossbar 19 is provided laterally between the first vertical bar 15 and the second vertical bar 16. A connecting plate 21 extends from the movable frame 2 directly above the central crossbar 19. A telescopic rod 5 is provided in the middle of the second crossbar 14. The free end of the telescopic rod 5 passes through the central crossbar 19 and connects to the connecting plate 21. The telescopic rod 5 can drive the movable frame 2 to move vertically. The telescopic rod 5 can be an electric telescopic rod 5 or a hydraulic telescopic rod 5, etc. The telescopic rod 5 can drive the movable frame 2 to move vertically, which is equivalent to the fixed frame 1. This improves the convenience of raising and lowering the support leg.

[0034] In some embodiments, the movable frame 2 includes a longitudinally arranged base 22 and a vertically arranged vertical seat 23. A support seat 3 is provided on the base 22, and the vertical seat 23 is located at the lower end of the base 22. A locking assembly 4 is provided at the upper end of the vertical seat 23. A connecting plate 21 extends from the middle of the vertical seat 23, and the outer side of the vertical seat 23 is adjacent to the inner side of the first vertical rod 15 and the second vertical rod 16. A slide rail and a slide groove can also be provided between the vertical seat 23 and the first vertical rod 15 and the second vertical rod 16 to guide the movable frame 2.

[0035] When installing the support legs, it's easy for them to become uneven. This necessitates adjusting the tilt and circumferential direction of the support legs to align them with the installation position. Therefore, in some embodiments, the support base 3 is movably connected to the base 22, allowing the support base 3 to rotate and / or tilt relative to the base 22. During support leg installation, the rotation and / or tilting of the support base 3 allows adjustment of the tilt and circumferential position of the support legs, facilitating accurate installation and improving the ease of installation.

[0036] The support base 3 can be rotated by installing a protruding bearing on the base 22, connecting the support base 3 and the base 22 through the bearing, allowing the support base 3 to rotate relative to the base 22. Alternatively, a universal joint can be used to connect the base 22 and the support base 3.

[0037] In some embodiments, a spherical head 221 is provided on the base 22, and a spherical sleeve 31 is provided in the middle of the support 3. The spherical sleeve 31 is adapted to the spherical head 221 and is fitted around the spherical head 221. This allows the support 3 to rotate and tilt relative to the base 22. Bolts can also be passed through the spherical sleeve 31 to lock the spherical sleeve 31 and the spherical head 221, improving the safety of maintaining the support leg.

[0038] In some embodiments, a baffle 32 extends from the edge of the upper end face of the support base 3 to prevent the support leg from sliding out.

[0039] The locking assembly 4 can be a clamp. In some embodiments, the locking assembly 4 includes a connector 41, a first arc-shaped rod 42, and a second arc-shaped rod 43. One end of the connector 41 is disposed at the upper end of the movable frame 2, and the other end extends to form a first connector 411 and a second connector 412. The connecting ends of the first arc-shaped rod 42 and the second arc-shaped rod 43 are respectively hinged to the first connector 411 and the second connector 412. The free ends of the first arc-shaped rod 42 and the second arc-shaped rod 43 are separately disposed, thereby facilitating the enclosure of the support leg between the first arc-shaped rod 42 and the second arc-shaped rod 43. This improves the convenience of locking the support leg.

[0040] In some embodiments, the free ends of the first arc-shaped rod 42 and the second arc-shaped rod 43 extend into locking portions 421, and locking portions 421 are provided with locking holes 422 for threading bolts. This facilitates locking the support leg and ensures the safety of the support leg during transport.

[0041] Therefore, this application discloses a bracket for maintaining vehicle support legs. In this application, the lower end of the vehicle support leg is placed on the support base, and the upper part of the support leg is limited by a locking component to prevent the support leg from moving. This ensures the safety of the support leg when it moves. After the fixing bracket is moved to the installation position of the support leg, the support leg can be moved to the appropriate installation position by the vertical movement of the moving bracket, thereby improving the convenience of installing the support leg.

[0042] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
