Description

Technical Field

[0001] The utility model relates to the technical field of mechanical support frames, in particular to an adjustable support frame. Background Art

[0002] There are many types of mechanical equipment. When mechanical equipment is in operation, some of its components or even the mechanical equipment itself can perform different forms of mechanical movement. During mechanical assembly, it is necessary to use a mechanical equipment support frame to assist in supporting and installing the mechanical equipment, thereby protecting the mechanical equipment and enhancing the stability of the mechanical components during installation.

[0003] According to a publicly disclosed support frame for mechanical manufacturing (publication number: CN219132035U), in the above application, the movable plate is moved to one side of the supported object by rotating the threaded rod through a crank, and the movable plates on both sides clamp the supported object. The arrangement of multiple anti-slip particles on the movable plate and the arrangement of multiple rubber strips on the top of the support plate can play an anti-slip role, increase the friction between the object and the support plate, and greatly increase the stability of the supported object when being supported.

[0004] However, during actual use of the above-mentioned equipment, after the distance between the movable plates on both sides is adjusted to clamp the mechanical parts, the crank is in an idle state. At this time, the crank is only limited by the threaded connection between the threaded rod and the support plate. When the staff or other personnel accidentally touch the crank, it will easily cause the crank to rotate, thereby causing the clamping of the mechanical parts to loosen, affecting the safety of the mechanical parts during assembly. In view of this, we propose an adjustable support frame. Utility Model Content

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: an adjustable support frame, comprising a base 1, an electric telescopic rod 2 is fixedly installed on the upper surface of the base 1, and when the electric telescopic rod 2 is started, the adjusting box 3 can be driven to move linearly in the up and down directions, thereby driving the mechanical parts to adjust to different heights, an adjusting box 3 is fixedly installed on the top of the electric telescopic rod 2, and a clamping adjustment component 4 is arranged inside the adjusting box 3, and the clamping adjustment component 4 comprises: a screw, a handle, a moving block and a clamping plate, the rear end of the screw is rotatably connected to the inner back of the adjusting box 3, the moving block is threadedly connected to the outside of the screw, the clamping plate is fixedly installed on the upper end of the moving block, the front end of the screw penetrates the front inner wall of the adjusting box 3 and is fixedly installed with a handle, when the staff turns the handle, the screw can be driven to rotate, the outer wall of the moving block and the inner wall of the adjusting box 3 fit each other, when the screw rotates, the moving block can be driven to move linearly in the front and rear directions under the limit of the inner wall of the adjusting box 3, thereby adjusting the distance between the two clamping plates to clamp and fix mechanical parts of different specifications, and the front end of the adjusting box 3 is provided with an anti-mistaken touch component.

[0024] The anti-mistaken touch component includes: an annular groove 501, a protective tube 505 and a connecting block 509. The annular groove 501 is provided on the front side surface of the adjusting box 3. An annular limiting groove 502 is provided inside the annular groove 501. Limiting rings 503 are fixedly installed on the front and rear ends of the inner outer wall surface of the annular limiting groove 502. Through holes 504 are provided on the left and right ends of the limiting ring 503. The protective tube 505 is sleeved inside the annular groove 501. The inner wall of the limiting ring 503 and the outer wall of the protective tube 505 fit each other. The protective tube 505 can move and rotate linearly in the front and rear directions inside the annular groove 501. Limiting blocks 506 are fixedly installed on the upper and lower sides of the rear end of the outer wall of the protective tube 505. The outer wall of the limiting block 506 is aligned with the inner wall of the annular limiting groove 502. They fit each other. When the limit block 506 is aligned with the through hole 504, the protective tube 505 can perform a linear motion in the front-to-back direction inside the annular groove 501 without being restricted by the limit ring 503. When the limit block 506 moves to the front end of the annular groove 501, rotating the protective tube 505 can make the limit block 506 leave the through hole 504. At this time, the limit ring 503 at the front end can limit the limit block 506 and the protective tube 505, so that the protective tube 505 cannot perform a linear motion in the front-to-back direction. At the same time, the protective tube 505 will be sleeved on the outside of the handle of the clamping adjustment component 4 to prevent the handle from being accidentally touched, so as to prevent the staff or other personnel from accidentally touching the handle after the clamping adjustment component 4 is adjusted, causing the adjustment clamping of the mechanical parts to loosen, thereby affecting the clamping effect.

[0025] When the handle needs to be used, the protective tube 505 can be rotated so that the limit block 506 is aligned with the through hole 504 and the protective tube 505 is moved backward so that the limit block 506 enters the gap between the limit ring 503 at the rear end and the rear inner wall of the annular limit groove 502. At this time, the protective tube 505 can be rotated to make the limit block 506 leave the through hole 504, and the limit ring 503 at the rear end will limit the limit block 506 to prevent the protective tube 505 from obstructing it when the handle is rotated. At the same time, the rubber tube 507 is completely located inside the annular groove 501 and will not hinder the rotation of the handle.

[0026] A rubber tube 507 is fixedly installed inside the protective tube 505. When the protective tube 505 moves forward, the rubber tube 507 will be driven to move synchronously. At this time, the rubber tube 507 will be sleeved on the outside of the handle and slightly squeezed between the handle, so that the rubber tube 507 fills the inside of the anti-skid groove on the outside of the handle. As the rubber tube 507 moves forward, impurities and sludge on the outside of the handle and the inside of the anti-skid groove will be pushed out to prevent the sludge impurities from adhering to the outside of the handle and affecting the use of the handle and the anti-skid performance of the anti-skid groove. A chamfer 508 is provided at the front end of the interior of the protective tube 505. When the protective tube 505 moves to the front end, the front side surface of the rubber tube 507 fits against the front side surface of the handle. At this time, the rubber tube 507 will completely push the sludge impurities out of the handle, so that the sludge impurities fall onto the chamfer 508 and fall downward along the inclined surface of the chamfer 508 to avoid accumulation inside the protective tube 505. The rear end of the chamfer 508 is located at the same horizontal plane as the front side surface of the rubber tube 507.

[0027] The connection block 509 is fixedly installed at the front end of the outer wall of the protection tube 505 . The staff can move the protection tube 505 through the connection block 509 , so as to facilitate the operation of the protection tube 505 .

[0028] An indicator block 601 is fixedly installed on the upper end of the front surface of the adjustment box 3. The indicator block 601 is located directly above the protective tube 505. Indicator grooves 602 are provided on both ends of the outer surface of the protective tube 505. When the protective tube 505 needs to leave the limit of the limit ring 503, the protective tube 505 can be rotated to align the indicator groove 602 with the indicator block 601. At this time, the limit block 506 will be aligned with the through hole 504, which is convenient for the staff to judge the position of the limit block 506.

[0029] In the present invention, when in use, after the clamping adjustment component 4 is adjusted to clamp the mechanical component, the protective tube 505 can be rotated to align the indicating groove 602 with the indicating block 601, and after the limiting ring 503 on the limiting block 506 is released, the protective tube 505 is pulled forward to the front end through the connecting block 509. In the process of the protective tube 505 moving forward, the rubber tube 507 will move to the outside of the handle and fill the inside of the anti-slip groove on the outside of the handle. As the protective tube 505 moves, the rubber tube 507 will push the sludge and impurities on the outside of the handle and the inside of the protective groove forward to clean them. When the protective tube 505 moves to the front end , the sludge and impurities will completely fall onto the chamfer 508 and slide outward along the inclined surface of the chamfer 508, preventing the sludge and impurities from adhering to the handle and affecting the use and the anti-slip performance of the anti-slip groove. As the protective tube 505 reaches the front end, the protective tube 505 is rotated so that the limit block 506 leaves the through hole 504. At this time, the limit ring 503 at the front end will limit the protective tube 505, making it impossible for the protective tube 505 to move in a straight line in the front and rear directions, and the handle is prevented from being accidentally touched to prevent the staff or other personnel from accidentally touching the handle after the clamping adjustment component 4 is adjusted, causing the adjustment clamping of the mechanical parts to loosen, affecting the clamping effect.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
