The specific embodiment
Below we come container door locking device of the present utility model done further with specific embodiment in conjunction with the accompanying drawings and elaborate; in the hope of setting forth structure of the present utility model and working process more cheer and brightly, but can not limit protection domain of the present utility model with this.
Container door locking device general structure of the present utility model is identical with traditional door lock assembly, structurally all include handle 1, handle set 2, locking bar and rivet 4, handle set 2 is fixed on the locking bar of freight container, and on handle 1 and handle set 2, be equipped with rivet hole 11,12 corresponding to rivet 4, pass the rivet hole 11 of handle 1 and the rivet hole 21 on the handle set 2 by rivet an end of handle 1 is fixed on the handle set 2.But, just can easily handle be separated with handle set if there is the people that rivet is destroyed, and then open container door easily, this just is unfavorable for the safe antitheft of freight container.
And the creative part of door lock assembly of the present utility model is also to be provided with an embedded burglar-proof mechanism between handle and handle set, even this burglar-proof mechanism falls in that the rivet that connects handle and handle set is destroyed, as long as the handle free end of locking can't move, the lawless person also can't remove handle and handle set, reach antitheft purpose, strengthened the safety of freight container door lock.
On concrete structure design, the utility model all designs respectively handle and handle set, sets forth in conjunction with the accompanying drawings respectively below.
The structure of handle 1 as shown in Figure 2, Fig. 2 is the structural representation of handle in a kind of container door locking device of the utility model.As seen from the figure, the cardinal principle contour structures of this handle 1 and the structure of conventional handle just as, and, also be provided with rivet hole 11 corresponding to rivet 4 in order to be connected with handle set 2.The place of embodying the utility model innovation part is, rivet hole 11 eccentric settings the on the handle 1 are not according to being positioned on the line of centers of conventional design, but is positioned at a side of line of centers.And be provided with a position-limited trough 12 in the end of handle 1, this position-limited trough 12 penetrates handle 1 as rivet hole, and position-limited trough 12 has only an end opening, and its opening is towards off-centre one side of rivet hole deflection line of centers.To be arranged at a side of line of centers be to be installed on the handle set 2 in order not influence handle to rivet hole 11 off-centre on this handle 1.So substantially, just present and collude shape in the end of handle 1.In the structure design of optimizing, position-limited trough 12 is a deep-slotted chip breaker, and the opening of this deep-slotted chip breaker is greater than the external diameter of position limiting structure.For more accurate, it is on the involute of axle that the line of centers of deep-slotted chip breaker 12 is positioned at rivet hole 11 axis on the handle 1.
The structure of handle set 2 as shown in Figure 3, Fig. 3 is the structural representation of handle set in a kind of container door locking device of the utility model.As shown in the figure, on the handle set 2 except be provided with rivet hole 21 as prior art corresponding to rivet 4, also be provided with a position limiting structure 3 corresponding to handle 1 upper limit position groove 12, this position limiting structure 3 equals the distance of position-limited trough 12 distal-most end apart from rivet hole 11 axis on the handle 1 apart from the distance of rivet hole 21 axis on the handle set 2.
Handle 1 and state after handle set 2 is connected as shown in Figure 4, Fig. 4 is handle and the handle set structural representation during non-locking still in the utility model container door locking device.Handle 1 is installed on the handle set 2, and the rivet hole 21 that passes on rivet hole 11 and the handle set 2 on the handle 1 by rivet 4 is connected the two.At this moment, under locking state not, the position limiting structure 3 of the position-limited trough 12 on the handle 1 on handle set 2.Under the two locking state, the position limiting structure 3 on the handle set 2 just embeds in the position-limited trough 12 on the handle 1.Because handle 1 could lock after rivet 4 rotates, so the position limiting structure 3 on the handle set 2 is that progressively transition extend in the distal-most end of position-limited trough 12 from open end.As shown in Figure 5, Fig. 5 is the structural representation the during locking of handle and handle set in the utility model container door locking device.
Above position limiting structure all is that the form with locating dowel pin occurs, certainly, except with the pin form, the position limiting structure on the handle set also comprises following version: as shown in Figure 6 and Figure 7, here be the version scheme drawing of two kinds of handle sets, wherein changing unit is with position limiting structure.Position limiting structure among Fig. 6 is a projection 5 inside on the handle set 2, and the quantity of this projection 5 is one.Position limiting structure is a projection 5 inside on the handle set 2 among Fig. 7, and this projection is relative two.
Certainly the theft-prevention structure with position-limited trough and position limiting structure combination can be one group, also can be many groups, and its purpose all is the same.
