Problems solved by technology

[0002] When the chain on the chain saw needs to be replaced due to wear and other reasons, since the sprocket 01 adopts a centrally symmetrical structure, such as figure 1 As shown, the user often installs the chain upside down, that is, taking the notch 211 on the right side of the chain tooth 21 of the chain 2 as a reference, as shown in figure 2 As shown, it should be installed clockwise according to the use regulations, but it was installed counterclockwise by the user. Although there will be no difficulty or failure to install during installation, when the chain saw is used, the chain is prone to serious damage. Vibration or even throwing the chain, off the chain, there is a huge potential safety hazard

Embodiment Construction

[0011] Such as figure 2 and 3 As shown, a chain saw chain anti-reverse assembly structure includes a sprocket 1, on which a sprocket tooth 11 is provided, and the sprocket tooth is provided with a snap-fit ​​structure and the right side of the chain tooth 21 of the chain 2. The gap 211 fits. The engaging structure is a protrusion 111 arranged on the left side of the sprocket teeth, and the shape and size of the protrusion correspond to the notch.

[0012] In the above-mentioned embodiment, a snap-fit ​​structure is added on the sprocket teeth to match the gaps on the chain teeth. The chain can only be installed on the sprocket when the chain is properly installed so that the protrusions fit well with the gaps. If the user reverses the chain, he will find that The installation is difficult, and it is difficult to install the chain well, so it is easy to prevent the user from reversely installing the chain and realize the safe operation of the chain saw.

Abstract

The invention discloses a reversed installation prevention structure for a chain of a chain saw. The reversed installation prevention structure for the chain of the chain saw comprises a chain wheel on which chain wheel teeth are arranged; and a clamping structure is arranged on the chain wheel teeth so that the chain wheel teeth are matched with gaps on the right sides of chain teeth of the chain. The reversed installation prevention structure is simple and is convenient to manufacture, and the clamping structure matched with the gaps on the chain teeth is added on the chain wheel teeth; only by positively installing the chain, the clamping structure can be well matched with the gaps, and the chain can be installed on the chain wheel; if a user installs the chain reversely, the installation is difficult and the chain is difficult to install; therefore, by the reversed installation prevention structure, the easy reversed installation by the user can be avoided, and safety work of the chain saw can be realized.

Description

technical field [0001] The invention relates to a chain saw structure, in particular to a chain saw chain anti-reverse assembly structure. Background technique [0002] When the chain on the chain saw needs to be replaced due to wear and other reasons, since the sprocket 01 adopts a centrally symmetrical structure, such as figure 1 As shown, the user often installs the chain upside down, that is, the notch 211 on the right side of the chain tooth 21 of the chain 2 is used as a reference, as shown in figure 2 As shown, it should be installed clockwise according to the use regulations, but it was installed counterclockwise by the user. Although there will be no difficulty or failure to install during installation, when the chain saw is used, the chain is prone to serious damage. Vibration or even throwing the chain, off the chain, there is a huge potential safety hazard. Contents of the invention [0003] The problem to be solved by the present invention is to provide a c...
