Abstract
The utility model discloses an easily disassembled expansion sleeve pin shaft device, which comprises a pin shaft, an expansion sleeve, a bolt and a pad, wherein one end of the pin shaft is conical and provided with an internal threaded hole; one end of the expansion sleeve is provided with a shaft shoulder and a conical inner hole; a tiny slit is formed between the conical inner hole and the outer surface; the conical end of the pin shaft is inserted into the conical inner hole of the expansion sleeve; the bolt is inserted into the shaft shoulder end of the expansion sleeve; and the expansion sleeve is connected with the pin shaft through the bolt. The easily disassembled expansion sleeve pin shaft device tensions a fixed part of a hinge structure through the expansion sleeve; the tensity of the expansion sleeve can be adjusted through the bolt; when the pin shaft device is required to be disassembled, the bolt is released for 3 to 4 turns; the head of the bolt is impacted by a copper bar and the like, so that the pin shaft is separated from the expansion sleeve, and the bolt and the pad can be disassembled; the expansion sleeve is taken out at first, and then the pin shaft is disassembled, so that the pin shaft device can be disassembled easily; due to the hinge structure with the easily disassembled expansion sleeve pin shaft device, a phenomenon of inconvenience in maintenance and disassembly can be avoided; the labor intensity is reduced; and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of pin shaft device, specifically is a kind of easy dismantle type ringfeder pin shaft device.
Background technique
Bearing pin generally is to be used with cotter pin, bolt, baffle plate etc., connects a moving element and dynamic component not, and it is widely used in the various machinery that need hinging structure.
Bearing pin also will increase along with pin diameter increases corresponding cotter pin diameter when being used with cotter pin at present, and when its cotter pin diameter surpassed 6mm, difficulty, effort were just compared in dismounting, increase labor intensity; And bearing pin is with bolt, when baffle plate is used, and assemble bearing pin at every turn and all will rotate it is alignd with the baffle plate fitting surface, and along with pin diameter strengthens, load increases, bearing pin rotates and also becomes difficulty, reduces working efficiency.
Summary of the invention
To the problem that above-mentioned existing technology exists, the utility model provides a kind of easy dismantle type ringfeder pin shaft device, and is easy to use, be easy to dismounting.
To achieve these goals, the technological scheme of the utility model employing is: a kind of easy dismantle type ringfeder pin shaft device comprises bearing pin, ringfeder, bolt and pad; Bearing pin one end is taper and has interior threaded hole; Described ringfeder one end tape spool shoulder also has cone-shaped inner hole, and open a finedraw between cone-shaped inner hole and the outer surface, and taper one end of bearing pin inserts in the cone-shaped inner hole of ringfeder; Ringfeder shaft shoulder end penetrates bolt, and ringfeder is connected with bearing pin through bolt.
As preferably, ringfeder is a round steel product.
As preferably, the finedraw spacing is 1-2mm.
As preferably, bearing pin is a round steel product.
The utility model passes through the fixed part tensioning of ringfeder with hinging structure, and passes through the rate of tension that bolt is regulated ringfeder, when needs release pin shaft device; Only unclamp bolt 3～4 circles, with bump bolt heads such as copper rods bearing pin and ringfeder are unclamped then, pull down bolt and pad; Take out ringfeder earlier; Thereby pull down the dismounting that bearing pin is accomplished pin shaft device like a cork again, the hinging structure of this easy dismantle type ringfeder pin shaft device is housed, can avoid the inconvenience of repair demolition; Reduce labor intensity, increase work efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the utility model ringfeder plan view;
Fig. 3 is the utility model ringfeder left view.
Among the figure: 1, pad, 2, ringfeder, 21, finedraw, 3, bolt, 4, bearing pin, 5, hinging structure, 6, movable structure.
Embodiment
To combine accompanying drawing that the utility model is described further below.
Like Fig. 1, Fig. 2 and shown in Figure 3, a kind of easy dismantle type ringfeder pin shaft device comprises bearing pin 4, ringfeder 2, bolt 3 and pad 1.Bearing pin 4 one ends are taper and have interior threaded hole; Ringfeder 2 one end tape spools shoulder also has cone-shaped inner hole; Ringfeder 2 need outwards rise greatly, opens a finedraw 21 between cone-shaped inner hole and the outer surface for this reason, and taper one end of bearing pin 4 inserts in the cone-shaped inner hole of ringfeder 2; Ringfeder 2 shaft shoulder ends penetrate bolt 3, and ringfeder 2 is connected with bearing pin through bolt 3.
As preferably, ringfeder 2 is a round steel product, and ringfeder 2 need bear certain intensity, selects for use soft materials such as plastics not reach requirement of strength, and soft materials oil rub resistance ability such as plastics, and ringfeder 2 selects for use common metal spare to get final product comprehensive economy, uses the round steel product.
As preferably, finedraw 21 spacings are 1-2mm, and finedraw 21 spacings require as long as satisfy to cooperate.
As preferably, bearing pin 4 is a round steel product, selects for use reason with ringfeder 2.
The utility model has cone-shaped inner hole one end to insert the fixed part of hinging structure 5 ringfeder 2; Penetrate the fixed part of taper one end of bearing pin 4 again from hinging structure 5 the other ends; Then penetrating needs in the movable structure 6; Penetrate at last in the endoporus of ringfeder 2, penetrate bolt 3, pad 1 and tighten, promptly accomplish the connection of pin shaft device from ringfeder 2 shaft shoulder ends.Tight a bolt 3, ringfeder 2 promptly expands outwardly, and ringfeder 2 is with the fixed part tensioning of hinging structure 5.When needs release pin shaft device, only unclamp bolt 3,3～4 circles, with bump bolt heads such as copper rods bearing pin 4 and ringfeder 2 are unclamped then, pull down bolt 3 and pad 1, take out ringfeder 2 earlier, thereby pull down the dismounting that bearing pin 4 is accomplished pin shaft device like a cork again.
