Description

Technical Field

[0001] The utility model relates to the technical field of motor accessories, in particular to an adjustable bracket. Background Art

[0002] Small motors generally need to undergo drag test experiments to detect their reliability. The test bench is generally equipped with two brackets at the head and tail of the motor. Currently, most motor brackets are fixed-structure brackets, which can only be fixed in matching motor slots, resulting in limitations in the fixed structure of the motor bracket. As a result, the motor bracket lacks certain functionality and cannot achieve the effect of multiple uses. At the same time, the two brackets cannot adjust the height and tilt angle. If the model of the test motor is to be changed, the bench needs to be remade, which increases the cost. Utility Model Content

[0029] See also Figure 1-4 An adjustable bracket includes a base 10, with a pad fixedly installed at the bottom of the base 10 to increase friction; the top of the base 10 is threadedly connected to a primary tube 30 through a stud 20, and the base 10 is removed from the bottom of the primary tube 30 to facilitate carrying of the entire bracket; a secondary tube 40 is inserted into the interior of the primary tube 30, and a tertiary tube 50 is inserted into the interior of the secondary tube 40. A pipe clamp assembly 60 is provided on the outer side of the top of the primary tube 30 and the secondary tube 40, and the pipe clamp assembly 60 can be used to lock the secondary tube 40 and the tertiary tube 50 after telescopic adjustment.

[0030] See also Figure 1-4 An extension rod 70 is fixedly installed on the top of the tertiary tube 50, a connecting ball 80 is fixedly installed on the top of the extension rod 70, two limiting rings 90 are fixedly installed on the outside of the extension rod 70, and a locking assembly 100 is mounted on the outside of the extension rod 70 and located between the two limiting rings 90. The locking assembly 100 can ensure that the mounting platform 130 is locked in position after rotation.

[0031] See also Figure 1-4 A mounting plate 110 is fixedly mounted on the outside of the locking assembly 100, and a ball sleeve 120 is movably mounted on the outside of the connecting ball 80. A mounting platform 130 is fixedly mounted on the top of the ball sleeve 120. The top of the mounting platform 130 is provided with a number of motor mounting holes of varying sizes, enabling connection to various devices and ensuring a secure connection. Four pneumatic rods 140 are movably hinged between the mounting platform 130 and the mounting plate 110. Applying force to the mounting platform 130 causes the four pneumatic rods 140 to extend and retract, thereby allowing the mounting platform 130 to be tilted and adjusted.

[0032] See also Figure 1-4 A strip-shaped notch 150 is provided on the top of each of the primary tube 30 and the secondary tube 40 , and a limiting strip 160 is fixedly installed on the inner wall of each of the primary tube 30 and the secondary tube 40 , and a limiting groove 170 corresponding to the limiting strip 160 is provided on the outer wall of each of the secondary tube 40 and the tertiary tube 50 .

[0033] See also Figure 1-4The angle between the limiting groove 170 and the strip notch 150 is ninety degrees. The tertiary tube 50 slides inside the secondary tube 40 through the limiting strip 160 and the limiting groove 170, and the secondary tube 40 slides inside the primary tube 30 through the limiting strip 160 and the limiting groove 170. This ensures that the secondary tube 40 and the tertiary tube 50 will not rotate after sliding.

[0034] See also Figure 4-5 The pipe clamp assembly 60 includes a C-ring 61, and wing plates 62 are fixedly installed at both ends of the C-ring 61. A strip hole 63 is opened inside the wing plate 62, and a screw 64 is inserted into the strip hole 63. One end of the screw 64 is threadedly connected to a nut 65, and the other end of the screw 64 is movably connected to a ball wrench 66. A gasket 67 is set on the outside of the screw 64 and located between the wing plate 62 and the ball wrench 66.

[0035] See also Figure 6 The locking assembly 100 includes a through hole 101 opened inside the extension rod 70, and a limit ring 102 is fixedly installed at the openings at both ends of the through hole 101. A T-shaped clamp 103 is inserted into the interior of the limit ring 102, and a spring 104 is fixedly installed at the other end of the T-shaped clamp 103. The outer side of the extension rod 70 is rotatably connected to a swivel 105, and the swivel 105 is fixedly embedded in the interior of the mounting plate 110; the inner wall of the swivel 105 is provided with a card slot 106 corresponding to the T-shaped clamp 103. There are several card slots 106, which are arranged in a ring with equal intervals. One end of the T-shaped clamp 103 inserted in the card slot 106 is hemispherical.

[0036] During use, by turning the ball wrench 66 to open it, the C-shaped ring 61 will be loosened, and the top openings of the primary tube 30 and the secondary tube 40 will be loosened, and then the secondary tube 40 can be extended and retracted from the primary tube 30, and the tertiary tube 50 can be extended and retracted from the secondary tube 40;

[0037] Conversely, the ball wrench 66 is rotated and closed, and the top openings of the C-ring 61, the primary tube 30 and the secondary tube 40 are tightened. The secondary tube 40 and the tertiary tube 50 are locked after adjusting the height, thereby adjusting the horizontal height of the motor installed on the mounting platform 130.

[0038] By rotating the mounting platform 130, the mounting platform 130 rotates synchronously with the mounting plate 110 through the pneumatic rod 140, and the mounting plate 110 rotates around the extension rod 70 through the swivel 105; when the force applied to the mounting platform 130 to rotate is stopped, the spring 104 will push the T-shaped clamps 103 on both sides thereof into the corresponding slots 106, and then lock the swivel 105 to ensure that the mounting platform 130 will not be displaced after the horizontal rotation position; during the adjustment process, the user can operate with one hand and quickly complete the fixation.

[0039] By applying force to the mounting platform 130, the two front pneumatic rods 140 are contracted and the two rear pneumatic rods 140 are expanded, and then the mounting platform 130 is tilted to ensure that the tilt angle of the motor installation is adjusted; at the same time, the surface of the mounting platform 130 is provided with a number of motor mounting holes of different specifications, ensuring that the mounting platform 130 is suitable for the purpose of installing different motors.
