Abstract

Provided are a buckle and a housing having the same buckle. The buckle is used for jointing a first part and a second part of the housing. The buckle is formed on the edge of the first part of the housing and comprises a joint part and a release part. The joint part is jointed with a matching part of the second part of the housing, and the release part is used for jointing a tool to enable the buckle to be disengaged. The buckle also comprises a backstop part, and the backstop part is formed on a motion path where the buckle is moved by the tool, and limits the motion stroke of the tool. By arranging the backstop part, the motion stoke of the tool for releasing the buckle is prevented from being overlarge, so that the buckle is prevented from deviating exceedingly and further being damaged as the motion stroke of the tool is overlarge, and the reliability and the service life of the buckle are further improved.

Description

Buckle and the housing that comprises this buckle

Technical field

The housing that the utility model relates to a kind of buckle and comprises this buckle, and relate in particular to buckle for the housing of electric equipment.

Background technology

Buckle is widely used in various aspects, is used for the different piece of housing, the especially plastic casing of product is fastened to together, and at needs, for example repairs or product can be taken the different piece of housing apart by tamper tool when reclaiming at product.

As shown in Figure 1, traditional buckle 100 comprises the junction surface 110 that snaps onto in the depression 200 that matches and is used for the release section 120 of untiing buckle by the instrument of for example screwdriver.This buckle 100 is formed on the edge of a part (not shown) of housing usually, and the depression 200 that matches with this buckle 100 is formed on the edge of one other component (not shown) of housing, thus, these two parts that snap onto in this depression 200 housing by the junction surface 110 with buckle 100 fasten to together.

When needing repairing this product, as shown in Figure 2, be inserted in the release section 120 of buckle 100 by 300 of for example screwdriver, and prize this buckle take the sidewall of this buckle 100 of formation of housing as fulcrum, until this junction surface 110 breaks away from 200 from caving in, thus two built-up sections of housing are taken apart.

Usually, after assembling product is finished, paste a guarantee label 400 in the position of buckle 100, with as the guarantee proof, privately take housing apart to prevent the user.

But in this traditional buckle 100, owing to repeatedly prize, the part that buckle 100 is connected with the edge of housing stands deflection repeatedly and produces fatigue damage; In addition, when utilizing instrument to prize buckle, cause sometimes buckle to damage owing to the deflection of instrument is excessive, and then cause product can't assemble or can't take apart.Therefore, need to traditional buckle be improved.

The utility model content

The purpose of this utility model is to improve the buckle of prior art, eliminates thus or alleviates at least the problems of the prior art.

According to the utility model, a kind of buckle is provided, this buckle is used for the first of housing is connected together with second portion, described buckle is formed on the edge of first of described housing, and comprise junction surface and release section, this junction surface will engage with the mating part of the second portion of described housing, and described release section is used for joining tool, so that described buckle is thrown off, wherein, described buckle also comprises the stopper section, and this stopper section is formed on the motion path that described instrument prizes described buckle, and limits the movement travel of described instrument.

By this stopper section is set, the movement travel of instrument that can prevent from discharging described buckle is excessive, thus, avoids causing described buckle deflection excessive owing to this movement of tool stroke is excessive, and then causes buckle to damage, and then improve reliability and the life-span of buckle.

Preferably, described junction surface and described release section form roughly L shaped, and are arranged on the described edge, so that form the depression that receives described instrument between described release section and the described edge.

Preferably, the end at described junction surface forms taper.Utilize the junction surface of taper, be beneficial to this junction surface is snapped in the corresponding mating part.

Preferably, described instrument be inserted in the described depression and the edge that forms described buckle on it as the fulcrum rotation, thus, described buckle is thrown off.

Preferably, described stop part is formed on the rotate path of described instrument, stops thus the rotary distance of described instrument greater than throwing off the required distance of described opening.

Preferably, described stop part is formed on the edge with the perpendicular housing in the described edge that described buckle is set.

Utilize the utility model, can prevent that described buckle from by excessive deformation, improving the useful life of described buckle thus.

Description of drawings

Above of the present utility model and other purposes, feature and advantage will be by with reference to the accompanying drawings to becoming clearer in the detailed description of the preferred embodiment of the present utility model, among the figure:

Fig. 1 is the schematic diagram that traditional buckle is shown;

Fig. 2 illustrates schematic diagram how to dismantle buckle; And

Fig. 3 is the schematic diagram that illustrates according to buckle of the present utility model.

Embodiment

Below, describe in detail according to preferred implementation of the present utility model with reference to accompanying drawing.

With reference to Fig. 3, be formed on according to buckle 10 of the present utility model on the edge 20 of the first part of housing, and comprise junction surface 11 and release section 12, this junction surface 11 is for the mating part (not shown) of the second part that snaps onto the housing that will cooperate, be similar to shown in Figure 1ly, this mating part can be formed in any parts that can match with the junction surface such as pit, stage portion or block on the edge of this second part.

As shown in Figure 3, this buckle 10 is roughly inverted L-shaped, and forms perpendicular to the edge 20 of housing.Junction surface 11 consists of a limit of this inverted L-shaped buckle 10, and end forms taper.Thus, be convenient to junction surface 11 is snapped in the mating part of the second part of housing.

Release section 12 forms another limit of inverted L-shaped buckle, forms thus depression between release section 12 and described edge 20, and for use in the instrument 30 that discharges this buckle 10, for example screwdriver inserts wherein.

On the shell rim on release section 12 tops, be formed with stopper section 13, this stopper section 13 is positioned at the top of this release section 12.When instrument 30 prizes buckle 10, instrument 30 take at the edge 20 of housing as the clockwise direction rotation of fulcrum in Fig. 3, thus, the end at junction surface 11 and the mating part of the second part are thrown off, and when instrument 30 is rotated further, this instrument 30 will contact with described stopper section 13, stop thus this instrument 30 to continue rotation.Thus, prevent buckle 10 excessive deflection, and then prevent that buckle 30 from rupturing owing to excessive deflection causes the edge 20 of housing,, prolonged the life-span of buckle 10 that is.

Although in Fig. 3, show the top that stopper section 13 is formed on release section 12,, in fact stopper section 13 can be formed on any position, as long as this stopper section 13 is arranged in the movement travel that the movement locus of this releasing tool 30 limits this instrument thus.

Although top reference preferred implementation of the present utility model has specifically described the utility model, but should be understood that, the utility model is not limited to above-described execution mode, but under the prerequisite that does not deviate from marrow of the present utility model, those skilled in the art can make various modifications and variations, and these modifications and variations all should fall in claims and the equivalent restricted portion thereof.
