Abstract
The invention discloses an improved chain plate mounting structure of an electric chain saw, comprising a case body, a chain plate mounted on the case body and a chain plate retaining mechanism which is arranged on the case body and used for keeping the chain plate stable during mounting, wherein the chain plate retaining mechanism comprises a U-shaped elastic clamping body of which the tail end is mounted on the case body, two elastic rod end parts of the elastic clamping body are provided with flanges, and the wall surface at the tail end of the chain plate is provided with a longitudinal open elongated slot for clamping the elastic clamping body. By adopting the mounting structure disclosed by the invention, an operator can mount an end cover of a chain saw without clamping the chain plate and a chain, so that the chain plate and the chain are simpler and more convenient to mount, and the convenience and comfort in the process of mounting the chain plate and the chain are greatly improved.
Description
Technical field
The present invention relates to chain saw, be specifically related to a kind of chain board mounting structure of electric chain saw.
Background technology
Electric chain saw is a kind of traditional electric tool, is widely used in fields such as the carpenter of family, gardens maintenance, forest lumbering.When using chain saw, its carrier bar and chain often need and be installed from the chain saw dismounting, to clear up carrier bar, change chain or store chain saw after work.In traditional structure and operating type, chain need be looped around earlier on the carrier bar, the carrier bar that will install chain then is placed into the relevant position on the chain saw; Need this moment with hand steered firmly carrier bar and chain, and then the end cap of chain saw is installed to the relevant position, tighten the screws makes end cap compress carrier bar.In this installation process, before loading onto the end cap of chain saw, carrier bar and chain are not held or are fixed on the chain saw, need the operator helping carrier bar and chain could well finish this work.For addressing this problem, also occur in the industry such as the relevant position on chain saw a magnet being installed, when carrier bar is installed, carrier bar is adsorbed on the method on the chain saw.But, adopt its defective of mode of magnet to be: 1.The price comparison of magnet is expensive; 2.Magnet is being adsorbed onto carrier bar on the chain saw in a flash, and strength is bigger and easily produce the sound of bump; 3. magnet is after being adsorbed onto carrier bar on the chain saw, and its magnetic force is bigger and produce bigger frictional force thus, makes the horizontal mobile power that need be bigger to carrier bar, and this inconvenient user moves with pre-tensioner chain the manual lateral of carrying out of carrier bar.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of carrier bar improved mounting structure of electric chain saw, adopt this mounting structure operator to need not helping again carrier bar and chain, the end cap of chain saw just can be installed, make that the installation of carrier bar and chain is easier, greatly improved convenience and comfortableness when carrier bar and chain are installed.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of carrier bar improved mounting structure of electric chain saw, comprise casing ontology, be installed in the carrier bar on the casing ontology, it is characterized in that: also comprise being located at keeping the stable carrier bar maintaining body of carrier bar when being used for installing on the casing ontology.
Preferably, described carrier bar maintaining body comprises that end is installed in the U-shaped elastic clamping body on the casing ontology, and two elastic rod ends of elastic clamping body are provided with flanging, and described carrier bar tail end wall is provided with a longitudinal opening elongated slot that is used for clamping elastic clamping body.The opening elongated slot has certain length, for carrier bar provides certain space along the movement of the length direction of opening elongated slot, can make the user move carrier bar and tension chain.
Improved, described flanging outer end is by one transition of circular arc limit, and the opening elongated slot of being convenient to carrier bar snaps in.
Improved, described flanging is inner by two transition of circular arc limit, and the opening elongated slot of being convenient to carrier bar is deviate from.
Improved, the outside of two elastic rod end flangings of described elastic clamping body also is provided with an extension, passes the opening elongated slot during installation, is convenient to press U-shaped elastomer with receiving to press, and the opening elongated slot of being convenient to carrier bar more snaps in.
Improved, described extension outside wall surface is enclosed tapered configuration from inside to outside.
Preferably, described casing ontology comprises casing and is installed in casing mold insert on the casing that described U-shaped elastic clamping body is installed on the described casing mold insert.
The outside wall surface of the terminal axial direction of U-shaped elastic clamping body is provided with and clamps platform, the casing mold insert is provided with and the described terminal corresponding U-shaped draw-in groove of the elastic clamping body that clamps platform that is provided with, institute's elastic clamping body is installed in the U-shaped draw-in groove by screw, and U-shaped draw-in groove diapire face and elastic clamping body end are provided with screwed hole.
Preferably, described carrier bar screws by end cap and is connected on the casing ontology.
Structure of the present invention is very simple and practical, adopts a U-shaped elastic clamping body, and its blind end is fixed on the chain saw, and the elastic rod openend is towards the chain saw outside.Yi word pattern opening elongated slot with carrier bar when carrier bar is installed snaps on the U-shaped elasticity folder, and the elasticity folder has just maintained carrier bar.The yi word pattern opening elongated slot of the middle part of elastic clamping body and carrier bar is proper Elastic Contact, so only need the very little power just can horizontal mobile carrier bar.So it is low that the present invention has realized cost, simple and practical, easy to operate purpose.
