Abstract
The utility model discloses a spring checking cylinder with a novel locking mechanism, which comprises a cylinder body, wherein a clamp is arranged on the cylinder body and passes through a plurality of locking mechanisms for locking, the locking mechanism comprises a locking bolt and a nut engaged with the locking bolt, a one-way tooth form projection is arranged on one end face of the nut, the direction of the one-way tooth form projection is the same with the winding direction of the locking bolt, which can reinforce the fastening effect. The spring checking cylinder cannot reverse due to the one-way tooth form projection on the end face of the nut, the nut is difficult to rotate in opposite direction after an air gun hardens up the bolt, thereby the deficiency that because the nut engaged with the bolt is loosened or privately rotated to detach, which causes parts are strongly popped up by a strong spring to easily hurt people is prevented, the security performance is enhanced, the structure is simple, and the cost is low.
Description
Technical field
The utility model relates to the locking of spring brake cylinder front band, is specifically related to a kind of spring brake cylinder with novel locking mechanism.
Background technique
Spring braking has brute spring in the chamber, owing to the loosening of bolt nut engaged or rotate the dismounting nut privately and can cause brute spring to eject component are powerful, very easily hurt the people, Safety performance is low.
Summary of the invention
The technical problem that the utility model solves just provides a kind of spring brake cylinder with novel locking mechanism, can prevent because with the loosening of bolt nut engaged or rotate the dismounting nut privately and can cause brute spring to eject component are powerful, very easily hurt people's shortcoming, thereby improved Safety performance, and simple in structure, cost is low.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of spring brake cylinder with novel locking mechanism, comprise cylinder body, cylinder body is provided with clip, clip is by several locking mechanism locking, described locking mechanism comprises that lock bolt reaches nut engaged with it, and it is characterized in that: an end face of described nut is provided with unidirectional toothed projections.
Preferably, it is identical that the direction of described unidirectional toothed projections and lock bolt screw direction, can strengthen fastening effect.
The utility model is owing to adopt technique scheme, because the unidirectional toothed projections on the nut end face is irreversible, so the reverse turn of the urgent bolt back nut of air gun is difficulty very, thereby prevent because with the loosening of bolt nut engaged or rotate the dismounting nut privately and can cause brute spring to eject component are powerful, very easily hurt people's shortcoming, improved Safety performance, and simple in structure, cost is low.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model embodiment's an overall structure schematic representation;
Fig. 2 is a lock bolt structural representation among Fig. 1;
Fig. 3 is a nut structure schematic representation among Fig. 1;
Fig. 4 is Fig. 3 left view.
Embodiment
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, embodiment for a kind of spring brake cylinder with novel locking mechanism of the utility model, 1 is the cylinder body of spring brake cylinder among the figure, cylinder body 1 is provided with clip 2, clip 2 is locked by locking mechanism, described locking mechanism comprises that lock bolt 3 reaches nut engaged 4 with it, lock bolt 3 is a square neck bolt, one end face of described nut 4 is provided with unidirectional toothed projections 41, it is identical that the direction of described unidirectional toothed projections 41 and bolt screw direction, can strengthen fastening effect, the unidirectional toothed projections on nut 1 end face is irreversible, so the reverse turn of the urgent bolt back nut of air gun is very difficult; This nut and square neck bolt form smooth, a non-removable locking mechanism.The utility model is applicable to the locking of all kinds of spring brake cylinder front bands.
Claims (2)
1. spring brake cylinder with novel locking mechanism, comprise cylinder body (1), cylinder body (1) is provided with clip (2), clip (2) is by several locking mechanism locking, described locking mechanism comprises that lock bolt (3) reaches nut engaged (4) with it, and it is characterized in that: an end face of described nut (4) is provided with unidirectional toothed projections (41).
2. according to the described a kind of spring brake cylinder with novel locking mechanism of claim 1, it is characterized in that: it is identical that the direction of described unidirectional toothed projections (41) and lock bolt screw direction.
