Abstract

An opening and closing device for an upper cover of an oven is mounted between the upper cover and a baking tray of the oven, wherein the upper cover can be connected onto the baking tray in a fastening and closing manner. The opening and closing device is characterized in that the upper cover is provided with a body and end covers arranged on two sides of the body, two opposite lateral protecting plates are arranged at the top end of the baking tray and respectively positioned on the inner sides of the corresponding end covers, a spring with flexible restoring force is arranged between each end cover and the corresponding lateral protecting plate and can balance the weight of the upper cover at any time, one end of each spring is fixed onto the respective end cover, and the other end of each spring is fixed onto the respective lateral protecting plate. Compared with the prior art, the opening and closing device can easily open the upper cover by only applying less external force when opening the upper cover, and lead opening of the upper cover to be more labor-saving. Moreover, the springs are hidden inside the oven, and the appearance of the opening and closing device is more beautiful and neater.

Description

The closing device of baking oven loam cake

Technical field

The utility model relates to a kind of baking oven loam cake, particularly relates to a kind of closing device of baking oven loam cake.

Background technology

At present, the loam cake of outdoor gas oven adopts stainless steel material, enamelled pressed steel material or aluminium die casting side plate to add enamelled pressed steel more, in the ordinary course of things, for the quality that guarantees to roast, loam cake all is to adopt double-decker, and is more thick and heavy, and along with the increase of oven size, the also corresponding increase of the size of loam cake so the weight of loam cake can further increase along with the increase of size, will relatively be required great effort during unlatching.

In order to make the open operation of loam cake become comparatively light, have in the prior art various auxiliary opening devices are set in loam cake, as oil pressure or elastic device, but structure is comparatively complicated mostly; Outer setting balancing weight at body of heater is also arranged, come the weight of balance loam cake by balancing weight, make the unlatching of loam cake become more light, but because balancing weight is to expose to outside the body of heater and directly be connected the exterior surface rear end, in carrying and moving process, be easy to balancing weight be damaged or balancing weight is lost, and in case connect the rope fracture of balancing weight, also can pound and hurt sb.'s feelings, cause unnecessary damage.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of simple and compact for structure, the easy for installation and more light labour-saving of bell unlatching baking oven loam cake closing device is provided at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the closing device of this baking oven loam cake, it is installed between the loam cake and barbecue dish of described baking oven, described loam cake is connected on the described barbecue dish opening or closing, it is characterized in that: described loam cake has body and is arranged on this body end covers at two sides, the top of described barbecue dish is provided with and lays respectively at inboard and two side guard plates that establish relatively of corresponding described end cap, be provided with the elastic-restoring force spring of the described loam cake weight of balance at any time between described end cap and the corresponding described side guard plate, one end of this spring is fixed on the described end cap, and the other end of this spring is fixed on the described side guard plate.

As preferably, offer aperture on the described end cap, be equipped with first screw in this aperture, an end hook of described spring is located on the end of described first screw, also is connected with the nut that is used for fixing described spring one end on the end of this first screw.Nut can holddown spring an end, guarantee that spring one end can't deviate from from first screw end, guarantee connection reliability.

As further preferred, offer screwed hole on the described side guard plate, be equipped with second screw in this screwed hole, another end hook of described spring is located on the end of described second screw.The inboard of side guard plate is stretched in the end of second screw, and side guard plate is the other end of holddown spring directly, need not the end of second screw attaching nut.

As preferably, the opening and closing of loam cake are hinged and connected by a rotating shaft between described end cap and the corresponding described side guard plate for convenience.

Compared with prior art, advantage of the present utility model is: by between the side guard plate of the end cap of loam cake and barbecue dish spring being set, make the elastic-restoring force of spring can be at any time balance each other with the gravity of loam cake, when opening loam cake, only need apply less external force, just can very like a cork loam cake be opened, make that opening of loam cake is more laborsaving; And, because spring is arranged between end cap and the side guard plate, only both ends of the spring need be fixed getting final product respectively, simple in structure, easy for installation; In addition, spring is to be hidden within the baking oven, and outward appearance is more beautiful and clean, and isolates by side guard plate between spring and the barbecue dish inner chamber, avoids the high temperature deformation of spring, prolongs spring service life.

Fig. 3 is two (under the loam cake openings) of the user mode figure of the utility model embodiment.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 3, specific embodiment of the utility model, this loam cake closing device is installed between the loam cake and barbecue dish 2 of outdoor gas oven, the loam cake of baking oven has body 11 and is arranged on this body end covers at two sides 12, the front portion of body 11 also is provided with handle 13, the top of barbecue dish 2 is provided with between 22, two side guard plates 22 of two side guard plates that lay respectively at corresponding end cap 12 inboards and establish relatively and is provided with baffle plate 21;

Wherein, be provided with the elastic-restoring force spring 3 of balance loam cake weight at any time between the end cap 12 of each side and the corresponding side guard plate 22, offer aperture 121 on the end cap 12, be equipped with first screw 41 in this aperture 121, one end hook of spring 3 is lived first screw 41 and is fixed on the end cap 12, also is connected with the nut 5 that prevents that spring one end from deviating from the end of first screw 41; Offer screwed hole 221 on the side guard plate 22, be equipped with second screw 42 in this screwed hole 221, the other end of spring 3 hooks second screw 42 and is fixed on the side guard plate 22;

And, offer first hinge hole 122 on the end cap 12 of each side, offer second hinge hole 222 on the corresponding side guard plate 22, be hinged and connected by a rotating shaft 6 that is located in first hinge hole 122 and second hinge hole 222 between end cap 12 and the side guard plate 22, make loam cake be connected on the barbecue dish and also can overturn with respect to the barbecue dish.
