Embodiment
Below in conjunction with drawings and Examples the present invention is done more detailed description.
The invention discloses a kind of keyboard holder of compatible polytypic mount inlet, extremely shown in Figure 3 in conjunction with Fig. 1, offer mount inlet 30 on the cabinet door 3 of electrical equipment or the wall, this keyboard holder is installed within the mount inlet 30, described keyboard holder includes a rack body 1, relative both sides of described rack body 1 are respectively equipped with at least one group of screens assembly 10, another relative both sides of described rack body 1 are respectively equipped with at least one group of buckle assembly 11, when described keyboard holder is installed on mount inlet 30, screens assembly 10 offsets with the edge of mount inlet 30, and buckle assembly 11 engages with the edge of mount inlet 30.Wherein, can be according to the shape of keyboard holder and mount inlet 30 and the structural feature of the two, screens assembly 10 and buckle assembly 11 residing positions are arranged flexibly, for example, screens assembly 10 is arranged at the left and right sides of rack body 1, be screens assembly 10 along transverse distribution, buckle assembly 11 is arranged at the up and down both sides of rack body 1, namely buckle assembly 11 longitudinally distributes.In the practical application; can also with the location swap of screens assembly 10 with buckle assembly 11, should be noted that herein the evolution of above-mentioned two kinds of assemblies includes but not limited to the transverse and longitudinal exchange; so the replacement of having done on this basis, change etc. all should be within protection scope of the present invention.
On the basis of above-mentioned keyboard holder structure, the composition structure and the working principle that the present invention is directed to screens assembly 10 and buckle assembly 11 propose respectively following two embodiments:
Embodiment 1:
In conjunction with Fig. 3, Fig. 4 and shown in Figure 5, described screens assembly 10 includes a bent plate 100, described bent plate 100 includes the first side plate 100a at an angle to each other and the second side plate 100b, the edge of described the first side plate 100a and mount inlet 30 offsets, the second side plate 100b is connected with rack body 1 elasticity sliding motion, so that rack body 1 is when being installed within the mount inlet 30, the first side plate 100a can keep out the edge at mount inlet 30 automatically.
In order to realize the elasticity sliding motion of second side, be provided with an Elastic medium 101 between described the second side plate 100b and the rack body 1, the end that this second side plate 100b is a shape setting and its bottom and Elastic medium 101 offsets, the other end of described Elastic medium 101 and rack body 1 offset, in the practical application, this Elastic medium 101 can be the elastic members such as spring, bow-shaped shrapnel.
For example, when Elastic medium 101 is spring, be the bottom of the second side plate 100b of shape setting and be protruding with the first column piece 102, be fixed with the second column piece 103 on the described rack body 1, the two ends of described Elastic medium 101 are sheathed on respectively on the first column piece 102 and the second column piece 103.But this is a preferred embodiment of the present invention, is not limited to the present invention, in other embodiments of the invention, and the linkage structure that can also adopt other types according to resilient characteristic or the structural feature of Elastic medium 101.
In order to limit the sliding trace of the second side plate 100b, be fixed with two limiting stoppers 106 that are oppositely arranged and are inverted L-shaped on the described rack body 1, described the second side plate 100b is arranged between two limiting stoppers 106 and can reciprocatingly slides.
In the present embodiment, be a relative bending in two ends of the second side plate 100b of shape setting and be formed with two kinks 104, be provided with accordingly positioning block 105 with two kinks 104 on the described rack body 1, described positioning block 105 is positioned within this shape.Under the elastic reaction of Elastic medium 101, bent plate 100 outwards slides, and stops until kink 104 is kept out when positioning block 105, thereby has limited the stroke of bent plate 100 and avoided this bent plate 100 to drop from rack body 1.
Embodiment 2:
In conjunction with Fig. 3, Fig. 6 and shown in Figure 7, described buckle assembly 11 includes a buckle 110, described buckle 110 is slidingly connected with rack body 1 and its upper end portion is outward extended with projection 110a, its underpart is provided with at least one back-off 111, along the sliding trace of buckle 110 and be positioned at rack body 1 and be provided with the multistage pawl 112 of at least one row, described back-off 111 and multistage pawl 112 are unidirectional to be engaged, by back-off 111 and the multistage pawl 112 that cooperatively interacts the sliding position of buckle 110 is limited, in the time of within keyboard holder is installed on mount inlet 30, can manually outwards stir two buckles 110, until projection 110a is stuck in the edge of mount inlet 30, engage with the unidirectional of multistage pawl 112 by back-off 111 again, keyboard holder is fixed within the mount inlet 30.In the practical application, multistage pawl 112 can have pawl structure as much as possible, so that buckle 110 has larger stroke, thereby adapt to better the mount inlet 30 of Multiple Type, this buckle 110 can be that the plastic cement buckle also can be made of other materials with elasticity capacity simultaneously.
In order to improve the unidirectional ability of engaging of back-off 111 and multistage pawl 112, the underpart of described buckle 110 is provided with two back-offs 111, correspondingly is provided with the multistage pawl 112 of two row with two back-offs 111 on the described rack body 1.
In the present embodiment, also be provided with two independent pawls 115 on the described rack body 1, described independent pawl 115 is positioned at before the multistage pawl 112 and with multistage pawl 112 and has distance.Before keyboard holder is installed, two back-offs 111 of buckle 110 can be streaked respectively independent pawl 115, and described back-off 111 is between independent pawl 115 and multistage pawl 112, so that back-off 111 is limited between the two, and buckle 110 can not drop.Sliding trace along buckle 110, be disposed with many graduation lines 116 at rack body 1, this graduation line 116 can print or hot pressing at rack body 1, can obtain intuitively distance and the buckle 110 residing positions at the edge of buckle 110 and mount inlet 30 by graduation line 116, thereby be convenient to the clamped position of buckle 110 is adjusted.
In order to realize that buckle 110 can be on rack body 1 slides along default track, described buckle 110 is provided with two chutes 113, and described rack body 1 is provided with two slide rails 114, and described slide rail 114 is positioned within the chute 113 and the two is slidingly connected.
In conjunction with above-mentioned two embodiments, keyboard holder disclosed by the invention has and can elasticity keep out in the screens assembly 10 of mount inlet 30 and the buckle assembly 11 that can be sticked in mount inlet 30, since screens assembly 10 and buckle assembly 11 keep out and the engaging process in all have sliding stroke, so that keyboard holder can be installed within the mount inlet 3 of Multiple Type, and satisfy the compatible requirement of 3 pairs of keyboard holders of installation of electrical equipment mouth, avoided occurring because of the mount inlet 3 oversize or too small situations that cause to install, thereby reduced the installation difficulty of product, improved working efficiency, this keyboard holder need not perforate and is equipped with screw simultaneously, installation process is simple and convenient, this keyboard holder can be applicable to frequency variator or other electrical equipment fields, and is applicable on the frequency variator with a series of different models.
The above is preferred embodiment of the present invention, is not limited to the present invention, all modifications of making in technical scope of the present invention, is equal to and replaces or improvement etc., all should be included in the scope that the present invention protects.
