In prior art, toeguard is arranged on layer door or car sill, at least directly uses 5 GB/T 5783 M4 * 30 bolt-lockings on sill, supporting nut GB/T 6170 M4, plain cushion GB/T 95 4, bullet pad GB/T 93 4 in addition.The patent documentation of publication number CN102367144 A has disclosed a kind of sill component, and its toeguard adopts flathead screw and ground sill bracket fixed connection.The connection mode of above prior art need to screw each nut while installing successively, complex operation, and man-hour used, more and required accessory was more, and cost is higher.
So those skilled in the art are necessary further to improve this protective device and make it to be convenient to assembling, reduce costs.
Summary of the invention
For the defect of above-mentioned prior art and the technical matters of existence, the technical matters that the utility model solves is to provide a kind of elevator toeguard protective device of quick for installation, convenient and cost savings.
The technical scheme of the utility model technical solution problem is: elevator toeguard protective device, comprise sill, and toeguard, is characterized in that axially having mounting hole along described sill; Described toeguard length direction is provided with the locations that coordinates with described mounting hole.
Technique effect of the present utility model is: utilize locations and mounting hole to replace existing bolted connection, the assembly parts such as bolt, nut have not only been saved, and mounting hole and locations also have positioning action, during assembling, only need locations to insert in mounting hole and get final product, without tighten each nut loaded down with trivial detailsly.Adopt the design clearly easier for installation quick, the set-up time is also short, uses accessory few, and the prior art of comparing has outstanding technique effect.
Preferred technical scheme: described mounting hole and locations arrange respectively 2 and uniform at least.
Further technique effect, uniform a plurality of mounting holes and locations are conducive to Joint strenght and assembly unit is stressed evenly, reduces stress and concentrates on a certain zone of assembly parts.
Preferred technical scheme: described locations comprises a limiting section, a clamping part and an introduction part; Described limiting section is connected with described toeguard body, and described introduction part becomes arrow-shaped.
Further technique effect: be conducive to locations and insert mounting hole.
Preferred technical scheme: described locations is that pressing and bending forms on described toeguard body.
Further technique effect: be conducive to save material.
Preferred technical scheme: described clamping part and described sill body interference fit.
Further technique effect: interference fit is conducive to toeguard and firmly is arranged on sill, thereby reduces bolt, and the use of the assembly parts such as packing ring, further embodied cost savings.
Preferred technical scheme: described toeguard also has screw or bolt hole for screw or bolted connection.
Further technique effect: increase the bond strength that screw or bolted connection are conducive to further strengthen assembly parts.
Preferred technical scheme: described toeguard adopts stainless steel sheet or galvanized plate.
Preferred technical scheme: described mounting hole is a kind of square opening or circular port.
Further technique effect: this is two preferred embodiments of the utility model, and the contact area rate circular port of square opening and clamping part is larger, makes bond strength higher.
The utility model further provides the installation method of this protective device: at first, hand-held toeguard, point to mounting hole as direction take introduction part, along sill, moves axially until locations inserts mounting hole and is forced into locking; Secondly, bolt inserting bolt hole also screws with nut; Thereby toeguard is arranged on sill.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated, further illustrate advantage of the present utility model and reach the outstanding contributions with respect to prior art, understandable, following embodiment is only the detailed description to the better embodiment of the utility model, should not be construed as any restriction to technical solutions of the utility model.
The utility model mainly comprises sill 1, toeguard 2 etc.
As shown in Figure 1, 2, 3, sill 1 is a kind of hollow aluminium profile spare, along its axially spaced-apart, is evenly equipped with three square mounting holes 11, and its pore wall thickness is 2mm.
As shown in Figure 4,5, toeguard 2 is a kind of zinc coated sheet (also can adopt stainless steel sheet), three locationss 21 uniformly at intervals along its length at its top, it adopts the punch machining process one-shot forming and stays corresponding punching hole 22 at toeguard 2 bodies.As Fig. 6,7,8 and in conjunction with Fig. 4,5, locations 21 afterbodys do not thrust with toeguard 2 bodies and are connected.The part that locations 21 is vertical with toeguard 2 bodies forms limiting section 213, and the part parallel with toeguard 2 bodies forms clamping part 211, and itself and toeguard 2 body vertical distances are 1.5mm.End face becomes arrow-shaped and is formed slopely introduction part 212 slightly outwardly.
As described in Fig. 9,10, during installation, from sill 1 right side, move axially toeguard 2, at first the introduction part 212 of locations 21 is inserted in mounting hole 11, continue to be forced into forward until mounting hole 11 otch end faces prop up limiting section 213, because clamping part 211 is 1.5mm with toeguard 2 body vertical distances, mounting hole 11 hole walls are thick is 2mm, this moment, mounting hole 11 hole walls and clamping part 212 formed interference fit, utilized the elasticity of installing component body that toeguard 2 is fixedly mounted on sill 1.On toeguard 2 bodies, both ends and three locations 21 coaxial lines also have two bolts hole 23, penetrate bolt and further strengthen two parts bond strength with the bolted connection mode.
It is circular that another preferred embodiment of the utility model is that mounting hole 11 is offered, but while installing, circular hole wall and clamping part 211 area of contact are many not as last embodiment, and bond strength is not so good as last embodiment in the interference fit situation.
The utility model only needs locations 21 to insert mounting hole 11, adopts interference fit that toeguard 2 is fixedly mounted on sill 2, and quick and easy for installation, the set-up time is short, uses accessory few, and the prior art of comparing has shown outstanding technological advance.
The preferred embodiment of below the utility model having been created illustrates, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite without prejudice to the utility model creative spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
