Description

Photo frame backboard buckling device

The utility model belongs to the photograph framework, specifically refers to the buckling device of photo frame moulding and backboard.

The photo frame backboard manner of traditional common roughly has following several: a kind of is to nail on several pieces little sheets by different distance on the moulding of photo frame, in the time will fastening or open the backboard of photo frame, need only the little sheet of rotation to the appropriate location, or fasten backboard or freely take out backboard; Another kind be with slidably, the stator that has a screw is positioned in the track of moulding, then stator slided into suitable position, with screw stator is fixed again.Above-mentioned traditional photo frame backboard fixed form all has dismounting inconvenience, and the stator position is difficult for adjusting, and is easy to defectives such as damage.Therefore the applicant proposed the patent of a novel photo frame back board structure on June 17th, 94, the Taiwan application number is 83208567 to have authorized on February 11st, 95, and file an application in China on June 28th, 1994, to authorize February 5 nineteen ninety-five, the patent No. is 2194215770.2.This utility model is to adopt the flexure strip of a type, flexure strip two curved end is embedded in the holder at the moulding back side, thereby makes flexure strip push down backboard.This undoubtedly method with flexure strip fastening backboard, the fastening method that more traditional sheet and screw are fixed is more firm, more convenient.But embed on the other hand and when taking out flexure strip, because of the flexure strip volume less, bad firmly, and its manner is also not all roses, and improvements are still arranged.

Therefore main purpose of the present utility model is to improve on the basis that above-mentioned 2194215770.2 patent flexure strips fasten, it is more reasonable to propose a kind of manner, promptly when eliminating fastening, need not press flexure strip, just can eliminate fastening as long as stir flexure strip, loosening backboard.Undoubtedly for above-mentioned patent, this is an improvement with distinguishing feature.

Another purpose of the utility model is under same fastening principle, and the flexure strip of design various ways not only makes product diversification, can also satisfy different requirements.

The technical solution of the utility model comprises that a kind of flexure strip reaches the design of the moulding holder that is complementary with this flexure strip.Above-mentioned flexure strip is that the material with favorable elasticity is made, though it is an integral body, with regard to its effect, can be decomposed into compressing tablet to this integral body, catch, fore-set and top flat four parts.Compressing tablet is arc shaped and is used to push down backboard, catch props up on the position, block face position of holder to prevent that flexure strip from skidding off from holder, fore-set peaks in the catch groove with fixing flexure strip and makes it to produce elastic force, push down backboard, top flat is backward end of fore-set tail end, can embed groove, increase the stability of flexure strip.Need only the relevant position that each position of flexure strip is entered holder when therefore fastening, can tightly push down backboard, make it reverse mobile as long as promote compressing tablet when getting, can take out backboard to the direction of being obstructed except that fastening.

In sum, the utility model proposes photo frame backboard buckling device, and obviously to have a device easy, firmly, retracts easy characteristics, will particularly use for the making of photo frame great convenience is provided.

Details are as follows in conjunction with the accompanying drawings in the utility model detailed description, wherein:

The utility model Reference numeral is:

10 flexure strips, 14 top flats

11 compressing tablets, 20 holders

111 salient points, 21 block faces

112 barbs, 22 grooves

12 catch, 23 backboards

13 fore-sets, 24 glass

See also two main bodys of the design's photo frame backboard buckling device represented in the accompanying drawing 1,2,3, the correlation of flexure strip (10) and holder (20).Represented structural relation is identical in above-mentioned three width of cloth accompanying drawings, and difference is that they have represented the embodiment of three kinds of different flexure strips respectively.A holder (20) is arranged at photo frame moulding bottom as seen from the figure, and its front is used to install glass (24), and backboard (23) is installed at the back, and flexure strip (10) then snaps together holder and backboard.There is a breach on the upper left side of groove (22) for the groove (22) of placing fore-set (13) one in the said fixing seat (20), and the right is a rectangular block face (21).

Flexure strip (10) is an integral body of being made by elastomeric material, is illustrated below in conjunction with the structure of flexure strip (10) with holder (20).With regard to its effect, flexure strip can be divided in the groove that embeds holder (20) with the part that produces elastic force and stretch out the outer part of pushing down backboard (23) of groove (22).What embed groove (22) and small gap thereof has fore-set (13) and a top flat (14), is kept out on the block face (21) in holder with the rectangular catch of fore-set (13) (12).That stretches out groove (22) has a compressing tablet (11).The tail end of this compressing tablet (11) also can curve a barb (112) in addition, is convenient to promote flexure strip.

Therefore, the fore-set of flexure strip (10) (13) is inserted in the following groove (22) of holder (20), and catch (12) is propped up the block face (21) of holder (20), thereby fore-set (13) has an active force that makes progress, catch (12) has a downward active force, utilize making a concerted effort of fore-set (13) and catch (12), then compressing tablet (11) can fasten photo frame backboard (23) behind to live tightly.When eliminate fastening, when taking out flexure strip (10), need only flexure strip is outer along the direction of arrow in the figure dial, can take out flexure strip.If be provided with barb (112), then can stir barb and can take out flexure strip (10).

The design has proposed the embodiment of 6 kinds of flexure strips, and its operation principle is identical, but structural form is respectively had any different.Fig. 4, the catch (12) of expression flexure strip (10) form (the concrete fastening of this kind flexure strip is seen Fig. 1) by the curved right angle of fore-set (13); Fig. 5 is the mode (the concrete fastening seen Fig. 2) that another kind curves the right angle; The catch of Fig. 6 (12) is (the concrete fastening seen Fig. 3) that curves Ω shape; Catch among Fig. 7 ties up to the both sides of fore-set (13) one ends and cuts off one jiao, the part of cutting off to external pressure and with withstand the formation right angle; Catch among Fig. 8 (12) is to cut off in the middle of fore-set (13) one ends, the outwardly-bent and fore-set formation right angle the mouth of cutting off; Fig. 9 represents that flexure strip (10) is to be formed by the steel wire bending.

Figure 10,11, the other three kinds of embodiment of 12 expression flexure strips (10), as seen from the figure, the top flat of the flexure strip of these three kinds of forms (14), fore-set (13), catch (12) and compressing tablet (11) respectively with Fig. 1,2,3 represented identical, just cancel 3 barbs (112), and set up a salient point (111) in the inboard of compressing tablet (11), the effect of this salient point (111) is similar to barb, is used to stir flexure strip (10).Figure 13 is the outward appearance signal of the design's photo frame backboard fastening structure.
