Abstract

The utility model discloses a range hood hanger. The range hood hanger comprises a hanging plate and a hook arranged on the hanging plate; the range hood hanger is characterized in that the hook comprises a hook root part, the upper end of the hook root part is connected with the hanging plate, the lower end of the hook root part extends downwards to form an extension part, and the extension part is bent upwards to form a hooked part. As the extension part of the hook is formed to extend downwards from the hook root part, the range hood hanger is capable of effectively preventing the stress concentration phenomenon of the hook root part by converting the shear force exerted on the hook root part of the existing range hood hanger into tensile force, and therefore, the bearing capacity of the hanger and the safety performance in use are greatly improved.

Description

A kind of range hood hanging rack

Technical field

The utility model relates to a kind of hanger, particularly a kind of range hood hanging rack.

Background technology

Existing range hood adopts hanger to install conventionally, this hanger comprises link plate and hook, the link plate upper punch of hanger is shaped with 1～2 cut, by the section being formed by cut upwards bend hook, in addition, there is 1～2 corresponding rectangular hole shape mounting groove in the punching of range hood back, the mounting groove at range hood back is inserted in the hook on hanger, just realized range hood installation on the wall.

But make because hanger adopts steel plate, hook is to obtain by the mode of tearing on link plate base material, the material subpunch of link plate is determined to a section, then this section is upwards bent to form to hook.Like this, on the one hand, cause the cutting edge that has formed similar scissors between hook on hanger and link plate, this cutting edge contacts with the mounting groove at range hood back, cause vibration that the cutting edge that exists on hanger produces in the course of the work because of range hood and the weight of range hood self to tear the mounting groove on range hood, make the hanger of range hood from wall come off and smash kitchen tools or pound and hurt sb.'s feelings, reduced the security in using; On the other hand, after range hood hangs on hanger, root at hook is subject to the shearing force producing because of the gravity of range hood self, there is the concentrated phenomenon of stress, cause hanger to be easily torn at the root place of hook, thereby reduce the service life of hanger, and had certain potential safety hazard.

For this reason, the existing patent No. is that the Chinese utility model patent " range hood hanging rack " of ZL200920052014.2 discloses a kind of range hood hanging rack that can address the above problem, it comprises link plate, hook, and technical characteristics is to be respectively equipped with left end breach, right-hand member breach at the two ends, left and right of described hook.This utility model is by arranging the mode of breach, prevented that the cutting edge forming between hook on hanger and link plate from tearing the mounting groove on range hood, but this range hood hanging rack exists the very serious concentrated phenomenon of stress at the root of hook.For the stress of alleviating hook root is concentrated, someone designs in the both sides of Gua Gou root stress hole 3 is set, as shown in Figure 3, this stress hole has reduced the stress that hook root is subject to a certain extent, but do not change the power mode of action of range hood to hook, be that range hood is shear stress to hook active force, the shear stress that hook root is subject to is still very large, causes range hood in use to have certain potential safety hazard.

Utility model content

The technical problems to be solved in the utility model is the present situation for prior art, provides one can effectively fall stress concentration impact, and bearing capacity is strong, safe and reliable range hood hanging rack.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of range hood hanging rack, comprise link plate and be arranged on the hook on this link plate, it is characterized in that: described hook comprises hook root, the upper end of this hook root is connected with described link plate, the lower end of this hook root extends to form extension downwards, and this extension is upwards bent to form hook portion.

As improvement, described hook is formed by described link plate punching press bending, is provided with the through hole forming through punching press on described link plate, adopts integrated punching bending process hook, when being convenient to the processing of hook, has improved the efficiency of hook processing.

Improve again, between the through hole sidewall of the arranged on left and right sides of described hook and described link plate, be formed with respectively left breach and right breach, by left breach and right breach are set, increase the distance between hook sidewall and link plate, effectively prevented that the cutting edge forming between hook on hanger and link plate from tearing the mounting groove on range hood.

Improve, the end of described hook portion is provided with the afterbody of export-oriented bending again, lampblack absorber is hung over by the mounting groove at back on the hook of hanger and become convenient.

As preferred scheme, on described link plate, be relatively provided with two hooks, in the case of not increasing the quantity of hook, make hanger stressed more balanced.

Improve, described hook back is provided with convex gusset again, and described hook inner surface is provided with groove, has improved the bearing capacity of hook extension and hook portion.

Improve, described hook root front is provided with strengthening groove again, and the described hook root back side is provided with boss, has improved the bearing capacity of hook root.

Improve, described hook both sides are respectively provided with installing hole, have facilitated hanger to be installed on body of wall again.

Compared with prior art, owing to the utility model has the advantage of: the hook of existing range hood hanging rack is the form of extending from bottom to top bending from hook root to the top of hook, causing range hood is shearing force to the active force of hook, and the extension section of hook of the present utility model is from hook root to downward-extension, ensure that range hood is tension to the active force of hook, change into pulling force by the shearing force that hook root is subject to, can effectively prevent the appearance of the stress concentration phenomenon of linking up with root, the bearing capacity of hanger and the security performance of use are greatly improved.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.

As shown in Fig. 1 to 8, range hood hanging rack in this enforcement, formed by punching press bending process, comprise link plate 1 and be oppositely arranged on two hooks 2 on this link plate 1, this hook 2 comprises hook root 21, and the upper end of this hook root 21 is connected with link plate 1, and the lower end of this hook root 21 extends to form extension 22 downwards, this extension 22 is upwards bent to form hook portion 23, has ensured that range hood 4 is tension to the active force of hook.

In addition, between through hole 12 sidewalls that formed by punching press and the arranged on left and right sides of each hook 2, be formed with respectively left breach 121 and right breach 122 on link plate 1, like this by breach is set, increase the distance of linking up with between 2 sidewalls and link plate 1, effectively prevented that the cutting edge forming between hook 2 on hanger and link plate 1 from tearing the mounting groove 41 on range hood 4.Meanwhile, hook both sides are respectively provided with installing hole 11, have facilitated hanger to be installed on body of wall.

In addition,, for convenience of the mounting groove of range hood 4 41 being inserted on hook 2, be provided with the afterbody 231 of export-oriented bending in the end of the hook portion 23 of hook 2; In order further to improve the bearing capacity of hook 2 extensions 22 and hook portion 23, be provided with convex gusset 28 at hook 2 backs, hook 2 inner surfaces are provided with groove 27; In order further to improve the bearing capacity of hook root 21, on hook root 21 fronts, be provided with strengthening groove 211, hook root 21 back sides are provided with boss 212.
