Description
Technical Field
The utility model relates to a transportation equipment technical field, in particular to connection structure of chain and guide rail.
Background
The prior art chain structure is shown in figure 1, and comprises a shaft pin, an inner chain plate sleeved on the shaft pin and an outer chain plate connecting two inner chain plates, wherein a guide rail is required to be arranged for limiting and guiding when the chain is in operation, for example, a metal outer chain plate of a chain in a turning conveyor is matched with a plastic guide rail, the problem of the scheme is that the noise between the metal outer chain plate and the plastic guide rail is very high, and in addition, the structure can shorten the service life of the guide rail, so that the cost is increased.
SUMMERY OF THE UTILITY MODEL
To the not enough of prior art existence, the utility model discloses a main aim at provides the chain that can noise reduction, increase of service life reduce cost and the connection structure of guide rail.
In order to achieve the above purpose, the utility model provides a following technical scheme: a connecting structure of a chain and a guide rail comprises the chain and a plastic guide rail, wherein the chain comprises a shaft pin, an inner chain plate sleeved outside the shaft pin and an outer chain plate connected with the inner chain plate, the outer chain plate is provided with a through hole for the shaft pin to extend out, the surface of the outer chain plate is provided with a nano-scale microporous layer, the nano-scale microporous layer is provided with an encapsulating layer, and the thickness of the encapsulating layer is larger than the length of the shaft pin protruding out of the through hole.
Preferably, the edge of the encapsulating layer is provided with a rounding structure.
Preferably, the through hole of the rubber coating layer is provided with a clearance groove.
The utility model discloses have following advantage for prior art, increase the encapsulating layer in the outer link joint periphery of metal, the material of encapsulating layer is PA6-GF20, becomes plastics and plastics friction relation by original metal and plastics friction relation between outer link joint and the guide rail like this, has not only reduced the noise, has reduced wearing and tearing moreover for the life of guide rail has obtained the improvement, the cost is reduced. Wherein, the surface of the outer chain plate is provided with a nano-scale microporous layer, thus the nano injection molding with a tight connecting structure can be formed between the encapsulating layer and the outer chain plate. Wherein the guide rail is made of high molecular polyethylene. The thickness of the encapsulating layer is larger than the length of the protruding through hole of the shaft pin, so that the encapsulating layer can be prevented from interfering the shaft pin, and meanwhile, a sliding groove for preventing the shaft pin can be not required to be formed in the guide rail, and the encapsulating layer is directly contacted with the guide rail, so that the material consumption of the guide rail can be reduced, and the cost is further reduced.
Drawings
FIG. 1 is a cross-sectional view of a prior art chain and guide connection;
fig. 2 is a schematic structural view of a connecting structure of a chain and a guide rail according to the present invention;
fig. 3 is a cross-sectional view of a connection structure of a chain and a guide rail according to the present invention.
In the figure: 1. a chain; 2. a guide rail; 3. a shaft pin; 4. an inner link plate; 5. an outer link plate; 6. a through hole; 7. wrapping an adhesive layer; 8. a fillet structure; 9. and (5) avoiding a clearance groove.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, a connecting structure of a chain and a guide rail comprises a chain 1 and a plastic guide rail 2, wherein the chain 1 comprises a shaft pin 3, an inner chain plate 4 sleeved outside the shaft pin 3 and an outer chain plate 5 connected with the inner chain plate 4, the outer chain plate 5 is provided with a through hole 6 for the shaft pin 3 to extend out, the surface of the outer chain plate 5 is provided with a nano-scale microporous layer, the nano-scale microporous layer is provided with an encapsulating layer 7, and the thickness of the encapsulating layer 7 is greater than the length of the shaft pin 3 protruding out of the through hole 6.
Preferably, the edge of the encapsulating layer 7 is provided with a rounding structure 8. The fillet structure 8 prevents that the rubber coating layer 7 from cutting the hand, and is easier to use.
Preferably, the through hole 6 of the encapsulating layer 7 is provided with a clearance groove 9. The arrangement of the clearance groove 9 can prevent the encapsulating layer 7 from interfering with the shaft pin 3.
According to the connecting structure of the chain 1 and the guide rail 2, the rubber coating layer 7 is additionally arranged on the periphery of the metal outer chain plate 5, the rubber coating layer 7 is made of PA6-GF20, and the original metal and plastic friction relation between the outer chain plate 5 and the guide rail 2 is changed into the plastic and plastic friction relation, so that the noise is reduced, the abrasion is reduced, the service life of the guide rail 2 is prolonged, and the cost is reduced. Wherein, the surface of the outer chain plate 5 is provided with a nano-scale microporous layer, thus the nano injection molding with a tight connecting structure can be formed between the encapsulating layer 7 and the outer chain plate 5. Wherein the material of the guide rail 2 is high molecular polyethylene. The thickness of the encapsulating layer 7 is larger than the length of the shaft pin 3 protruding out of the through hole 6, so that the encapsulating layer 7 can be prevented from interfering the shaft pin 3, meanwhile, a sliding groove for preventing the shaft pin 3 does not need to be formed in the guide rail 2, and the encapsulating layer 7 is directly contacted with the guide rail 2, so that the material consumption of the guide rail 2 can be reduced, and the cost is further reduced.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
