Abstract
The utility model discloses an excavator shovel tooth protection plate and relates to the technical field of mechanical accessories. The protection plate comprises a protection plate body which is connected onto a shovel tooth and is matched with the shovel tooth to be used for protecting the shovel tooth, so that the abrasion resistance of the shovel tooth is improved. a pin hole is formed in the protection plate body and is used for being connected with the shove tooth. A connection portion is arranged at the rear end of the protection plate body, the connection portion and the protection plate body are in an integrated structure, and the protection plate body and the connection portion are in an L-shaped structure integrally. A snapping groove is formed in the upper portion of the connection portion at the bottom of the protection plate body which can be connected onto a shovel tooth fixing seat through the snapping groove, and a connection hole is formed in the bottom of the connection portion. The protection plate is simple in structure, novel in design, high in integral strength, good in abrasion resistance and capable of prolonging the shovel tooth service life and reducing the production cost.
Description
Technical field
The utility model relates to mechanical fitting technical field, is specifically related to a kind of excavator shovel tooth backplate.
Background technology
Excavator is indispensable plant equipment in various engineering constructions, and the teeth of excavator is subject to continuous wearing and tearing in construction, need to change in time.In order to reduce the cost, reduce the part of changing, the teeth of a lot of excavators is designed to two body structures, teeth is combined by teeth holder and spear, spear wearing and tearing are at work much larger than teeth holder, only need to change as a rule spear, the teeth holder long period just needs to change, and has reduced cost.In the middle of the teeth holder of this double-body bike teeth is thick by two with spear, thin pin is connected, and an elastic ring is installed in the middle of pin, and two parts are combined as a resilient key and used.During installation, first spear and teeth holder are installed together, then resilient key is squeezed in pin-and-hole.In use, along with the wearing and tearing of teeth, the stressed continuous increase of pin, causes pin to become curved, dismantles very difficult.
Utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, anti abrasive excavator shovel tooth backplate.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of excavator shovel tooth backplate, comprise a panel reality, this panel reality is connected on teeth, supporting with teeth, for the protection of teeth, improve the abrasion resistance of teeth, on described panel reality, be provided with a pin shaft hole, being used for connecting teeth uses, described panel reality rear end is provided with connecting portion, described connecting portion and panel reality are structure as a whole, the whole L-shaped structure of panel reality and connecting portion, on described connecting portion top, be positioned at panel reality bottom and be provided with a draw-in groove, by this draw-in groove, panel reality can be connected on teeth holder, described connecting portion bottom surface is provided with a connecting hole.
The cross section of the described draw-in groove structure that takes the shape of the letter U, inner wall smooth can well be fitted with teeth holder.
Described pin shaft hole is positioned at the middle part of panel reality.
Described panel reality smooth surface.
The beneficial effects of the utility model are: the utility model is simple in structure, modern design, and bulk strength is high, and abrasion resistance is good, can extend the application life of teeth, reduces production costs.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is Figure 1A-A sectional drawing.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As Fig. 1, shown in Fig. 2, a kind of excavator shovel tooth backplate, comprise a panel reality 1, this panel reality 1 is connected on teeth, supporting with teeth, for the protection of teeth, improve the abrasion resistance of teeth, on panel reality 1, be provided with a pin shaft hole 2, being used for connecting teeth uses, panel reality 1 rear end is provided with connecting portion 3, connecting portion 3 is structure as a whole with panel reality 1, panel reality 1 and the rear whole L-shaped structure of connecting portion 2 combination, on connecting portion 3 tops, be positioned at panel reality 1 bottom and be provided with a draw-in groove 4, by this draw-in groove 4, panel reality 1 can be connected on teeth holder, connecting portion 3 bottom surfaces are provided with a connecting hole.The cross section of draw-in groove 4 structure that takes the shape of the letter U, inner wall smooth can well be fitted with teeth holder, and pin shaft hole 2 is positioned at the middle part of panel reality 1, panel reality 1 smooth surface.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
