Embodiment
By the technology contents, the structure characteristics that specify the utility model, realized purpose and effect, know clearly below in conjunction with mode of execution and conjunction with figs. and give explanation.
See also Fig. 1, the bilateral locking element mode of execution of the utility model, this bilateral locking element are used to connect first member 1 and second member 2, comprise the first knob embedding 4, the second knob embedding 3, slide bolt 5, first control handle 8 and second control handle 7; First control handle 8 is fixed on first member 1, and second control handle 7 is fixed on second member 2; The said second knob embedding 3 is placed on the screw rod of slide bolt 5, with slide bolt 5 screw-thread fit; Second control handle 7 is placed in the second knob embedding, 3 peripheries, is used to control the rotation of the second knob embedding 3, thereby drives the advance and retreat of slide bolt 5; Said first control handle 8 is placed in the first knob embedding, 4 peripheries, and first control handle 8 is used to control the rotation of the second knob embedding 3, and the internal diameter of the first knob embedding 4 is provided with the screw thread that is complementary with slide bolt 5.
Consult Fig. 2; This bilateral locking element in use; Earlier second control handle 7 on rotation second member 2 advances thereby make the second knob embedding 3 drive the first knob embeddings 4 of slide bolt 5 on first member 1, after slide bolt 5 and the first knob embedding 4 screw togather fully; Rotate first control handle 8, thus locking slide bolt 5.First member 1 and second member 2 can be linked together closely.In the time will opening first member 1 and second member in 2 minutes; Rotate first control handle 8 on first member 1 earlier; Thereby the first knob embedding 4 is unclamped, then, rotate second control handle 7 on second member 2; Return to second member, 2 directions thereby drive slide bolt 5, till opening in 2 minutes to first member 1 and second member.When first member 1 and second member 2 are thrown off; Slide bolt 5 is drawn back; In order to prevent slide bolt 5 and the first knob embedding, 4 disengagements, cause slide bolt 5 to fall into the inside of second member 2, the present technique scheme is provided with a limiting board 6 in second member, 2 inside; Said limiting board 6 is provided with certain distance with the nut of slide bolt 5, is used for the distance that limit slippage bolt 5 is retreated.
The present technique scheme, mainly the screw rod through slide bolt 5 couples together first member 1 and second member 2, so the length of the screw rod of slide bolt 5 must be enough long, and first member 1 can be connected with second member 2 closely, do not throw off.Concrete, the length of the screw rod of the bolt of present technique scheme equals the thickness sum of the first knob embedding 4 and the second knob embedding 3 greatly.
In the improved technological scheme of certain of the utility model, the end that first member 1 and second member 2 have a common boundary is tubulose, and first control handle 8, second control handle 7 is provided with and the corresponding groove of tube-like envelope, and tube-like envelope is embedded in the groove.Through this improvement project, first control handle 8 and second control handle 7 can be respectively serves as that axle rotates with the housing of first member 1 and second member 2.The present technique scheme serves as that axle rotates with first member 1 and second member 2, thereby guarantees that first control handle 8, second control handle 7 can not misplace.
Consult Fig. 3, the end that first member 1 and second member 2 have a common boundary is equipped with groove, and groove floor is provided with opening, and first control handle 8, second control handle 7 place said aperture position.The design class of said first control handle 8 and second control handle 7 is similar to the structure of pull bar combination lock, safety box.This structure is convention in the existing technology, and this structure applications is in the present technique scheme, convenient with slide bolt 5 lockings.In use,, stir first control handle 8 and second control handle 7 through this opening, thus the advance and retreat of control slide bolt 5.First member 1 and second member 2 can be locked through plural bilateral locking element, thereby first member 1 can be connected with second member 2 more closely.
In order to make linking together that first member and second member can be permanent; The constituent material of the said first knob embedding, the second knob embedding, first control handle and second control handle of this technological scheme is metallic material like alloy; Adopt alloy material; Intensity is good, and is convenient and practical, is easy to processing.
In a kind of improved technological scheme of the utility model; The constituent material of the said first knob embedding 4, the second knob embedding 3, first control handle 8 and second control handle 7 not only can be alloy, can also be other plastic material, to the enough hard demand that just can satisfy use of the intensity that will guarantee material; Constituent material like them can also be for being the ABS engineering plastics; The constituent material that this technological scheme adopts, not only practical, and also cost is lower.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
