Description
Technical field
The utility model relates to the structure-design technique field, relates in particular to a kind of subrack system.
Background technology
In existing subrack system, the general mode of clamping up and down that adopts of space bar is connected with sheet metal component.For the clamping that guarantees space bar and sheet metal component firm; Take to increase more the clamping area and up and down clamping way in the opposite direction realize; But simultaneously also increased requirement greatly,, will certainly cause before and after the space bar stressed or front and back to rock in case the cabinet mismachining tolerance is bigger to the cabinet crudy.
In the process that realizes existing subrack system, the designer finds that there is following problem at least in existing subrack system:
In existing subrack system, mostly the connected mode of module slot interval and cabinet sheet metal component is clamping up and down, and clamping is in the opposite direction up and down; The clamping area is bigger, and the dismounting difficulty requires high to the cabinet crudy; In case the cabinet mismachining tolerance is bigger, can causes and rock before and after the space bar or stressed.
The utility model content
The embodiment of the utility model provides a kind of subrack system.For achieving the above object, the embodiment of the utility model adopts following technical scheme:
A kind of subrack system, this system comprises: space bar and clamping sheet metal component;
Said space bar is at least two pairs of equidirectional draw-in grooves of the corresponding setting in both sides up and down, the equidirectional clamping up and down of said draw-in groove and said clamping sheet metal component;
Said space bar and said subrack system casing junction are provided with fixing hole and convexity, and said fixing hole is aimed at the said subrack system corresponding fixing hole in casing junction, and is fixing; The protruding clamping in said protruding clamping and subrack system casing junction.
Wherein, the cross section of said space bar draw-in groove adopts triangle clamping cross section.
Wherein, said fixing hole is used for fixing said space bar of self threading pin and said subrack system casing.
Wherein, said space bar adopts mould of plastics to be processed into.
A kind of subrack system that the utility model provides, both sides are corresponding up and down that at least two pairs of equidirectional draw-in grooves, clamping about said draw-in groove and said clamping sheet metal component are equidirectional be set through said space bar; Said space bar and said subrack system casing junction are provided with fixing hole and convexity, and said fixing hole is aimed at the said subrack system corresponding fixing hole in casing junction, and is fixing; The protruding clamping in said protruding clamping and subrack system casing junction.Owing to adopt Mould Machining, improved productivity ratio; Adopt the mode of clamping and screw to fix; Under the prerequisite that guarantees the degree of freedom, improve the efficiency of assembling and the success rate of subrack, reduced the application risk of space bar, simultaneously; Leg-of-mutton clamping cross section and increased the clamping intensity of guide rail, also reasonable use the space.

Embodiment
Below in conjunction with accompanying drawing a kind of subrack system that the utility model embodiment provides is described in detail.
A kind of subrack system configuration sketch map as shown in Figure 1, as to provide for the utility model embodiment; This subrack system comprises: comprising: said space bar is corresponding at least two pairs of equidirectional draw-in grooves 2, the said draw-in groove 2 and the equidirectional clamping up and down of said clamping sheet metal component of being provided with in both sides up and down;
Said space bar and said subrack system casing junction are provided with fixing hole 3 with protruding 1, and said fixing hole 3 and the said subrack system corresponding fixing hole aligning in casing junction are fixed; The protruding clamping in said protruding 1 clamping and subrack system casing junction.
Wherein, the cross section of said space bar draw-in groove adopts triangle clamping cross section.
Wherein, said fixing hole 3 is used for fixing said space bar of self threading pin and said subrack system casing.For example: the front and back displacement that can come the control interval plate in the utility model subrack system through subrack casing and space bar fixing hole through self threading pin; Space bar is identical with the sheet metal component clamping direction of subrack casing up and down; In case subrack is processed with error; Can adjust space bar through the degree of tightness of screw, thereby reduce its stressed risk, also effectively guarantee the firm of space bar.
Wherein, said space bar adopts mould of plastics to be processed into.As shown in Figure 2, face 4 flushes with the outer surface of subrack, and face 5 overlaps with the inner surface of subrack, is effective supporting surface of subrack.Like 6 among Fig. 2 is top, and 7 are the enlarged diagram of clamping face 1, and 8 is the profile of three clampings, and 9 is PCB draw-in groove enlarged drawing, and 10 is the rear portion, and 11 is the right view at rear portion; Space bar up and down respectively with the sheet metal component clamping of subrack casing, and the clamping direction is identical.Hit the face of connecing and clamping face 1 (as shown in Figure 3), clamping face is a triangle, and three clampings (like Fig. 4) had so both increased the clamping intensity of guide rail, had also saved the space, with limited space as much as possible left module for.Clamping face 2 is main clamping face, limits its left and right sides degree of freedom and rotary freedom (with subrack forward sight datum level is main-vision surface, down together); Simultaneously at the rear portion of space bar, i.e. PCB draw-in groove (its enlarged drawing is as shown in Figure 5), the top is connected with subrack through clamping; Limit its left and right sides degree of freedom and rotary freedom; Following self threading pin through M2.5-8 is connected (as shown in Figure 6) with the subrack casing, limits the degree of freedom of its front and back, if because subrack case mismachining tolerance causes space bar and subrack clamping difficulty more greatly; Can adjust the clamping that the screw degree of tightness is come the control interval plate through appropriateness, when guaranteeing the degree of freedom, also reduce the stressed risk of space bar.
A kind of subrack system that the utility model provides, both sides are corresponding up and down that at least two pairs of equidirectional draw-in grooves, clamping about said draw-in groove and said clamping sheet metal component are equidirectional be set through said space bar; Said space bar and said subrack system casing junction are provided with fixing hole and convexity, and said fixing hole is aimed at the said subrack system corresponding fixing hole in casing junction, and is fixing; The protruding clamping in said protruding clamping and subrack system casing junction.Owing to adopt Mould Machining, improved productivity ratio; Adopt the mode of clamping and screw to fix; Under the prerequisite that guarantees the degree of freedom, improve the efficiency of assembling and the success rate of subrack, reduced the application risk of space bar, simultaneously; Leg-of-mutton clamping cross section and increased the clamping intensity of said space bar, also reasonable use the space.
The above; Be merely the embodiment of the utility model; But the protection range of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field can expect changing or replacement in the technical scope that the utility model discloses easily, all should be encompassed within the protection range of the utility model.Therefore, the protection range of the utility model should be as the criterion by said protection range with claim.
