Abstract
The utility model discloses a protective cover-bolt combined device, which comprises a protective cover and a bolt, wherein an assembling hole is formed on the protective cover; the thread end of the bolt passes through the assembling hole of the protective cover; and an elastic R-shaped card is clamped at the thread end of the bolt. When the combined device is dismounted from a machine, the protective cover and the bolt can be still connected.
Description
Technical field
The utility model relates to the composite set of a kind of protective housing and bolt.
Background technique
In the existing mechanical equipment, protective housing is one of basic component.Be typically provided with pilot hole on the protective housing, be provided with screw with the body of the pairing machinery of pilot hole, the pilot hole that bolt passes protective housing is tightened in the screw on the body of machinery.When needs maintenance protective housing or other must be pulled down the protective housing operation, the bolt that will be fixed on usually on the protective housing screws out, bolt and protective housing are separated, the maintenance finish or other end of job after, again with protective housing by on the body that is bolted to machinery.In above-mentioned maintenance or other operation process, the part bolt may be lost because of various reasons, therefore cause equipped imperfect, thereby influence safety.Pertinent regulations have been put into effect in Europe at present in addition: the protective housing on the machine is when pulling down, and the bolt of fixing this protective housing can not leave protective housing.
The model utility content
The technical problems to be solved in the utility model provides the composite set of a kind of protective housing and bolt, and this device is when machine is pulled down, and its protective housing and bolt can link together.
For solving the problems of the technologies described above, the composite set of a kind of protective housing of the utility model and bolt, this device contains protective housing and bolt, protective housing is provided with pilot hole, the threaded end of bolt passes the pilot hole of protective housing, also contain flexible R shape card, elasticity R shape card is installed on the threaded end of described bolt.
Owing to clamp an elasticity R shape card on the threaded end of bolt, so protective housing is when machine is pulled down, and protective housing and bolt can link together all the time.Guaranteed so equipped complete, thereby safety has obtained guarantee.
Description of drawings
Fig. 1 is the structural representation of the composite set of a kind of protective housing of the utility model and bolt.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is that the elasticity R shape shown in Fig. 1 is stuck in the structural representation when not being out of shape
1. protective housings among the figure, 2. bolt, 3. pilot hole, 4. elasticity R shape card.
Embodiment
Among Fig. 1, the composite set of a kind of protective housing of the utility model and bolt, this device contain protective housing 1 and bolt 2, and protective housing 1 is provided with pilot hole 3, and the threaded end of bolt 2 passes the pilot hole 3 of protective housing 1.This device also contains flexible R shape card 4, and as shown in Figure 3, elasticity R shape card 4 is installed on the threaded end of bolt 2, as shown in Figure 2.Owing to clamp an elasticity R shape card 4 on the threaded end of bolt 2, so protective housing 1 is when machine is pulled down, and protective housing 1 can link together all the time with bolt 2.Guaranteed so equipped complete, thereby safety has obtained guarantee.
