Abstract
The utility model belongs to the technical field of booster cylinders, and particularly relates to an anti-falling structure on a piston rod, which comprises a piston rod (1), a flange (2) arranged at the lower end of the piston rod and connected with the piston rod through threads, and an anti-falling structure, wherein the anti-falling structure comprises a connecting piece (3), and the connecting piece is respectively connected with the piston rod (1) and the flange (2) and is used for preventing the flange from rotating relative to the piston rod; the piston rod is rotated in the direction of separating from the flange when the piston rod is used for a long time by adopting the existing structure, and the piston rod is accumulated continuously until the piston rod is separated from the flange, so that safety accidents are caused.
Description
Technical Field
The utility model relates to the technical field of booster cylinders, in particular to a structure for preventing a flange on a piston rod from falling off in the working process.
Background
The structure that the flange is combined with the piston rod is used for fixing a movable plate used on the booster cylinder at present, namely the flange is arranged at one end of the piston rod, the movable plate is fixedly connected with the flange, the piston rod is connected with the flange through threads, in order to prevent the flange from separating from the piston rod, the flange and the piston rod are fixedly connected through pretightening force when being installed, namely the flange is screwed on the piston rod, and loosening is prevented; by adopting the structure, the device is used for a short time, no problem exists, but because the bearing force of the piston rod is large and is particularly influenced by alternating load, or the piston rod and the piston are influenced by lateral force, firstly, the piston rod can be loosened relative to the flange, then, the piston rod rotates relative to the flange in the use process, in the process, the initial positions of the flange and the movable plate on the flange are gradually reduced, and finally, the flange and the movable plate fall off in the long-term use process, so that safety accidents occur.
Disclosure of utility model
In order to overcome the defects in the prior art, the utility model aims to provide an anti-falling structure on a piston rod.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an anticreep structure on piston rod, includes the piston rod, locates the piston rod lower extreme and rather than passing through threaded connection's flange, still includes anticreep structure, anticreep structure includes the connecting piece, and the connecting piece is connected with piston rod, flange respectively for prevent that the flange is rotatory relative to the piston rod.
Preferably, the anti-drop structure further comprises a straight-shaped mounting groove arranged in the end face of one end of the mounting flange on the piston rod; two transverse grooves which are positioned on the same straight line are arranged in the bottom surface of the flange; when the flange is installed, the flange rotates to a set position on the piston rod, and the two transverse grooves and the installation groove are positioned on the same straight line; the connecting piece is a metal strip which is embedded in the mounting groove and the two transverse grooves and is fixedly connected with the flange or the piston rod.
With the adoption of the structure, at least one side mounting groove is formed in the side wall of one end of the mounting flange on the piston rod, and at least one inner side mounting groove corresponding to the side mounting groove is formed in the inner wall of the flange; the connecting piece is a metal strip with a square section, at least one connecting piece is inserted into a space formed by combining the side mounting groove and the inner side mounting groove.
Because the flange adopts threaded connection with the piston rod lower extreme to set up the connecting piece and radially fix the two, prevent that the piston rod from rotating relative flange promptly, and then prevent that the flange from dropping from the piston rod, be favorable to stopping the potential safety hazard.

Detailed Description
In order to better understand the aspects of the present utility model, the present utility model will be described in further detail with reference to the drawings and embodiments.
As shown in fig. 1, the utility model provides an anti-drop structure on a piston rod, which comprises a piston rod 1, a flange 2 arranged at the lower end of the piston rod and connected with the piston rod through threads, and an anti-drop structure, wherein the anti-drop structure comprises a connecting piece, and the connecting piece is respectively connected with the piston rod and the flange and used for preventing the flange from rotating relative to the piston rod. Namely, the flange is prevented from rotating relative to the piston rod in the use process, so that the piston finally drops off, and the personal and property safety is endangered.
Example 1, as shown in fig. 2-3.
In this embodiment, the anti-disengaging structure further includes a linear mounting groove 101 disposed in an end face of one end of the mounting flange on the piston rod 1; two transverse grooves 201 which are positioned on the same straight line are arranged in the bottom surface of the flange 2; when the flange is installed, when the flange rotates to a set position on the piston rod, the two transverse grooves 201 and the installation groove 101 are positioned on the same straight line; the connecting piece 3 is a metal strip which is embedded in the mounting groove and the two transverse grooves and is fixedly connected with the flange or the piston rod.
Here, when the flange 2 is mounted, the connecting member 3 is fixed to the bottom surface of the flange by means of screws, preventing the flange from rotating the piston rod 1 during use.
As shown in FIG. 5, by adopting the structure, the piston rod 1 can be effectively prevented from rotating relative to the flange 2 in the using process, and then the flange and the movable plate 5 are prevented from falling off from the piston rod 1, so that potential safety hazards are favorably avoided.
In the above description, it should be noted that the terms "mounted," "connected," and the like should be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; the two parts can be directly connected or indirectly connected through an intermediate medium, and can be communicated with each other inside the two parts; "disposed" is understood to mean "mounted to, disposed on," and includes mounting means such as fixed mounting, movable mounting, and the like.
It is apparent that the above-described embodiments are only some embodiments of the present utility model, but not all embodiments, and the preferred embodiments of the present utility model are shown in the drawings, which do not limit the scope of the patent claims. This utility model may be embodied in many different forms, but rather, embodiments are provided in order to provide a thorough and complete understanding of the present disclosure. All equivalent structures made by the content of the specification and the drawings of the utility model are directly or indirectly applied to other related technical fields, and are also within the scope of the utility model.
