Description

Technical Field

[0001] This utility model relates to the field of jack technology, and in particular to an extension arm device for jacks. Background Technology

[0002] The core purpose of a jack is to lift and support heavy objects using mechanical or hydraulic principles. It is widely used in fields such as automobile repair, construction engineering, and industrial manufacturing. When performing various tasks, there are often situations where a large-tonnage jack is needed, but the available space is smaller than the jack itself, making it impossible to use the jack directly and affecting work efficiency.

[0003] Chinese patent CN211664621U discloses a jack with an easy-to-replace top block. The jack uses a movable rod that moves to the left through a through-hole, which then moves the fixed rod and sliding sleeve to the left. The sliding sleeve then pulls a spring to reset the jack. Finally, the sliding sleeve moves to the left, causing the fixed sleeve to move to the left through the opening until it is fixed inside the groove. This solves the problem of existing jacks having inconvenient top block replacement, leading to severe wear and affecting balance. However, it fails to address the issue of the jack being unusable when the usable space is smaller than the jack body.

[0004] In view of the above problems, developing an extension arm device for jacks to expand the application range of jacks and improve work efficiency has become an urgent issue for those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide an extension arm device for jacks, which solves the problem that jacks cannot be used when the space is smaller than the jack body, expands the application range of jacks, and improves work efficiency.

[0006] The objective of this utility model is achieved through the following technical solution: An extension arm device for a jack, characterized in that it includes a vertical beam, a mounting frame, a sleeve, and a support arm; the mounting frame and the support arm are respectively disposed on both sides of the vertical beam, the sleeve is fixedly connected to the vertical beam through the mounting frame, the mounting frame is disposed near the top of the vertical beam, the support arm is fixedly connected to the vertical beam near the bottom, the sleeve is sleeved on the piston rod of the jack, and the lifting component is located on the support arm; when the piston rod extends, it lifts the mounting frame, causing the vertical beam and the support arm to rise simultaneously, thereby raising the lifting component.

[0007] In the aforementioned extended arm device for a jack, the sleeve is transitionally fitted with the piston rod.

[0008] In the aforementioned extension arm device for a jack, the vertical beam is parallel to the sleeve axis of the sleeve.

[0009] The aforementioned extension arm device for a jack, wherein the mounting frame is made of angle steel with an included angle of 90°, and the plane of the mounting frame connecting the sleeve is perpendicular to the sleeve axis.

[0010] The aforementioned extension arm device for a jack has an arm made of angle steel with an included angle of 90°, and the surface of the arm that contacts the lifting component is perpendicular to the vertical beam. Beneficial effects

[0011] This utility model provides an extension arm device for a jack. When the extension arm is used in conjunction with the jack, the piston rod of the jack extends, lifting the mounting frame and simultaneously raising the vertical beam and the support arm, thereby raising the lifting component. This solves the problem that the jack cannot be used when the space is smaller than the jack body, expands the application range of the jack, and improves work efficiency.
