The utility model relates to a kind of button manhole cover liner plate, this liner plate body surface has radially well-distributed strip groove, one end of strip groove stretches out for equal diameter hole, spring is installed in strip groove and buckles piece, spring is fixedly connected with the one end of buckleing piece, the minimum length of button piece and spring is equal to the length sum in strip groove and equal diameter hole, the extreme length of button piece and spring is than the long 5-10cm of length sum in strip groove and equal diameter hole, and described button piece is connected with spring and holds that to have be highly the projection of 2-4cm.Adopt the technical solution of the utility model, user can make spring-compressed by pulling projection, thereby making to detain piece all enters in strip groove, this button manhole cover lining plate structure be designed with the steady installation that is beneficial to this liner plate, the service life of effective prolonged human port lid, save a large amount of manpower and materials and time, suitable applying.
Description
Technical field
The utility model relates to a kind of button manhole cover liner plate.
Background technology
The effect of liner plate is that protection is by lining structure, makes to be avoided inner or outside direct impact and friction by lining structure, and multi-form liner plate can be used to adjust by the state of kinematic motion of lining structure, thereby can extend by the service life of lining structure.
The general manhole cover with specific function needs liner plate, as thering is the manhole cover of heat insulation function, the manhole cover of the manhole cover of shock resistance, compressive resistance or there is manhole cover of antibacterial sterilization ability etc., these liner plates with the manhole cover of property all need special design just can make manhole cover reach special performance.If it is not in place that fruit is designed, the easy serious wear of manhole cover or have a strong impact on the product design of manhole cover inside, and need regularly to liner plate, safeguard or directly change, have a strong impact on production efficiency.Therefore, studying a kind of simple in structure, convenient and practical liner plate for manhole cover is the current problem that will study.
Utility model content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide a kind of simple in structure, convenient and practical liner plate for manhole cover.
The utility model solves the technical scheme that its technical matters adopts: a kind of button manhole cover liner plate, comprise liner plate body, liner plate body surface has radially four strip grooves of well-distributed, one end of strip groove stretches out for equal diameter hole, spring is installed in strip groove and buckles piece, spring is fixedly connected with the one end of buckleing piece, the minimum length of button piece and spring is equal to the length sum in strip groove and equal diameter hole, the extreme length of button piece and spring is than the long 5-10cm of length sum in strip groove and equal diameter hole, described button piece is connected with spring, and to have be highly the projection of 2-4cm to end.
Further, for easy to process, described liner plate body front is circular.
Further, for easy to process, described liner plate body front is square.
Further, the length of described strip groove is that liner plate body center is to 1/2 to 2/3 of edge length.
Further, for avoiding stress to concentrate and wearing and tearing, described liner plate body corner has chamfering structure.
Beneficial effect: the structure of button manhole cover liner plate of the present utility model is comparatively simple, user can make spring-compressed by pulling projection, thereby making to detain piece all enters in strip groove, by the equal diameter hole of this liner plate corresponding with mounting hole on manhole cover good after, projection is unclamped, make liner plate be installed on manhole cover, this button manhole cover lining plate structure be designed with the steady installation that is beneficial to this liner plate, the service life of effective prolonged human port lid, save a large amount of manpower and materials and time, suitable applying.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
1. liner plate bodies in figure, 2. strip groove, 3. spring, 4. button piece, 5. projection.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
A kind of button manhole cover liner plate as shown in Figure 1, comprise that positive is circular liner plate body 1, liner plate body 1 surface has radially four strip grooves 2 of well-distributed, one end of strip groove 2 stretches out for equal diameter hole, spring 3 is installed in strip groove 2 and buckles piece 4, spring 3 is fixedly connected with the one end of buckleing piece 4, the minimum length of button piece 4 and spring 3 is equal to the length sum in strip groove 2 and equal diameter hole, the extreme length of button piece 4 and spring 3 is than the long 5cm of length sum in strip groove 2 and equal diameter hole, described button piece 4 is connected with spring 3, and to have be highly the round bump 5 of 2cm to end, the length of strip groove 2 is that liner plate body 1 center is to 1/2 of edge length.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to claim scope.
