Abstract
The utility model relates to a locking device, in particular to a locking device for a positioning bolt. The locking device comprises the positioning bolt (1), a fixing plate (2), and so on; the outside of the fixing plate (2) is vertically provided with two limiting plates (3), the locking end of the positioning bolt (1) is of a polygonal column and provided with a locking plate (4) which is sleeved at the locking end of the positioning bolt (1), the width of the locking plate (4) corresponds to the distance of the two limiting plates (3), the outsides of the locking plate (4) and the locking end of the positioning bolt (1) are provided with a connecting plate (5), and the connecting plate (5) is connected with the locking end of the positioning bolt (1) and the locking plate (4) through bolts. The utility model uses the limiting plates (3) to block the locking plate (4), the locking plate (4) to block the positioning bolt (1), and then uses the connecting plate (5) to fix the locking plate (4) and the positioning bolt (1). The locking device has the characteristics of reasonable structure, convenient operation, is firm and reliable, and is not easy to loosen.
Description
Technical field
The utility model relates to a kind of locking device, specifically a kind of external locking device of holding down bolt.
Background technique
At present, traditional general structure of holding down bolt locking device is: after holding down bolt being passed the fixed plate in band silk hole, push up again on the parts that are positioned, the screwed in place bolt, then with being equipped with jack panel from that side near the parts that are positioned, the inboard that is positioning plate is fastening with holding down bolt, thereby reaches the purpose of bolt location.This locking mode owing to reasons such as vibrations, makes easily that fully jack panel is loosening, and influences its fastening effect in Product transport and using process; In addition, when the position that runs into holding down bolt between several parts, when the operating space is narrow and small, being difficult to will to be equipped with jack panel with instrument is fastened on the holding down bolt from the inboard of positioning plate, fastening not in place, the parts that are positioned just are subjected to displacement easily, have influenced fastening effect.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, easy to operate, fastening firm, difficult loosening holding down bolt locking device.
The technical solution adopted in the utility model is: a kind of holding down bolt locking device, the fixed plate that comprises holding down bolt and band silk hole, in the outside of fixed plate, the both sides in silk hole two limiting boards are set vertically, one end of described holding down bolt is the locking end, this locking end is the polygonal cylinder, the end face of locking end is provided with a hole, and the locking end of this holding down bolt passes the silk hole of fixed plate and reaches the outside of fixed plate; Locking end at holding down bolt is provided with latch, and this latch middle part is provided with the locking end of holding corresponding polygonal through hole and being placed in holding down bolt with the locking of holding down bolt polygonal, is provided with a hole in one side of through hole; The distance of the width of described latch and two limiting boards is corresponding, in the arranged outside of latch and holding down bolt locking end connecting plate is arranged, and this connecting plate is connected with latch with the locking end of holding down bolt by screw.
The locking end of described holding down bolt is arranged to square cylinder, and the through hole that is provided with on the latch is corresponding with described square cylinder, and is placed in the locking end of holding down bolt.
Because the utility model is arranged to the locking end of polygonal cylinder with an end of holding down bolt, with the end that the corresponding polygonal through hole on the latch blocks holding down bolt, blocks latch with limiting board again, restriction latch and holding down bolt rotate.The effect of connecting plate is to prevent that latch from coming off from the locking end of holding down bolt.The utility model has realized preventing that at the outside of fixed plate locking holding down bolt it is loosening that not only easy-to-operat, and locking effect is good.
Description of drawings

Fig. 2 is the left view of Fig. 1
Embodiment
Fig. 1 is a kind of embodiment of the present utility model, comprise holding down bolt 1, fixed plate 2, limiting board 3 and latch 4 etc., described fixed plate 2 is provided with the silk hole that cooperates with holding down bolt 1, in the outside of fixed plate 2, the both sides in silk hole two limiting boards 3 is set vertically.Described holding down bolt 1 one ends are the locking end, and an end is a positioning end, and holding down bolt 1 locking end is arranged to the polygonal cylinder, and present embodiment is a square cylinder, can also be triangle cylinder or Hexagon cylinder etc.The end face of holding down bolt 1 locking end is provided with a hole, and the square column type locking end of this holding down bolt 1 passes the silk hole of fixed plate 2, reaches between the outside, two limiting boards 3 of fixed plate 2.Locking end at holding down bolt 1 is provided with latch 4, and these latch 4 middle parts are provided with the corresponding polygonal through hole of polygonal cylinder with holding down bolt 1 locking end, and is stuck in the locking end of holding down bolt 1, and one side of through hole is provided with a hole on latch 4.The distance of the width of described latch 4 and two limiting boards 3 is corresponding, latch 4 be may be stuck on the locking end of two holding down bolts 1 between the limiting board 3, and be subjected to the restriction of two limiting boards 3 and can not rotate, be used to block the locking end of holding down bolt 1, thereby the rotation of restriction holding down bolt 1 prevents that it is loosening.Arranged outside at latch 4 and holding down bolt 1 locking end has connecting plate 5, and this connecting plate 5 is provided with two attachment holes, because be provided with a hole on holding down bolt 1 locking end end face and latch 4, sees Fig. 2.So connecting plate 5 can be connected with latch 4 with the locking end of holding down bolt 1 respectively by screw, thereby latch 4 is fixedlyed connected with holding down bolt 1, prevent that latch 4 and holding down bolt 1 from getting loose.
During use, fixed plate 2 and limiting board 3 are fixedly connected on correct position near the positioning element of wanting, Placement can be to weld, be spirally connected or riveted joint etc.The positioning end of holding down bolt 1 is passed the silk hole of fixed plate 2, push up on the parts that to locate, and guarantee to reach between the parts that to locate and the utility model the distance of designing requirement, then latch 4 is placed on the locking end of holding down bolt 1, with screw connecting plate 5 is installed in the outside of the locking end of latch 4 and holding down bolt 1 again, latch 4 is fixedlyed connected with holding down bolt 1, thereby be implemented in the outside locking and positioning bolt 1 of fixed plate 2.
This shows, the utlity model has rational in infrastructure, convenient operation, locking device fastening firm, Be difficult for the characteristics such as loosening.
