Abstract
The invention relates to a chain, which comprises a plurality of chain link sheet groups connected end to end in series, a plurality of pin shafts used for connecting the plurality of the chain link sheet groups in series, and an open space defined by the match of the plurality of the chain link sheet groups. The plurality of the pin shafts are accommodated in the open space at intervals, each chain link sheet group is provided with two facing chain sheet units, and the chain sheet units of different chain link sheet groups are mutually overlapped inside and outside in pairs. The chain is characterized in that the chain also comprises a protector; the protector integrally extends and is arranged on a top side of one chain sheet unit of one chain link sheet group, and is not connected with a top side of another chain sheet unit of the chain link sheet group; each chain sheet unit is provided with an inner surface most adjacent to the facing chain sheet unit; and the protector is provided with a shielding part which is positioned between the two inner surfaces and has the shielding function on the open space. The chain can integrally achieve the effects of good structural strength, exogenous impurity intrusion prevention, dust prevention, impact resistance, and the like.
Description
Technical field
The present invention relates to a kind of chain, be meant a kind of impact resistance especially and can prevent that foreign matter from invading or the long-pending attached chain of dust.
Background technique
Well known ground, chain are to arrange in pairs or groups mutually to use as transmission, transportation with sprocket wheel.Yet, because form is for the gap structure of the gear piece engagement of sprocket wheel between the chain sheet of chain, bearing pin, chain roller, be to belong to open fully kenel, cause foreign matter intrusion, holding quite easily, the lighter influences the moving smooth degree of chain (as producing different sound, increasing resistance) of chain, and weight person then can cause chain releasing, disintegration or fracture; Moreover each chain link of chain is to be the pivot joint tandem, and is extremely limited on strength of connection, in case when being subjected to external force collision, have disintegration at the sound equally, the fracture anxiety is considered; In addition; for the moving smooth degree of the chain of promoting chain, usually can be in the chain roller surface of chain or other articulate on position and be coated with lubricant oil, but so on the contrary be stained with glutinous, long-pending attached dust easily; and if the careless false touch of personnel just can stay the oil stain stains that are difficult to remove on clothing.
In view of this, as Fig. 1 and shown in Figure 2, the relevant common means that additionally install inverted U protecting cover 3 on the chain 1 additional that are used in of dealer are in the hope of improving the above-mentioned shortcoming that chain 1 is had when operating.Wherein, inverted U protecting cover 3 is according to institute's suitable chain 1 specification and give other custom-made moulding, and can double team, button organizes on the outer chain sheet 11 of chain 1, in order to chain 1 is produced protective action.Yet this kind inverted U protecting cover 3 is in using, and is not only bulky and fabricating cost is high, can increase relatively chain 1 load, take up room and the power consume, particularly, can influence the smooth degree of chain 1 when turning.
Summary of the invention
The present invention's purpose is to provide a kind of impact resistance, and can prevent that foreign matter from invading or the long-pending attached chain of dust.
Chain of the present invention, comprise chain nodal plate group that most headtotails are string, most in order to be connected in series the bearing pin of this majority chain nodal plate group, and one by this majority open space that chain nodal plate group matches and defines, this majority bearing pin is to be placed in this open space at interval, each chain nodal plate group has the chain blade unit that two-phase is faced, the chain blade unit of different chain sheet groups is stacked mutually inside and outside in twos, it is characterized in that:
This chain also comprises at least one consubstantiality and extends the wherein protector of a chain blade unit that is arranged at one of them chain nodal plate group, this protector is to extend on the top side of above-mentioned chain blade unit, and do not link to each other with another chain blade unit, each chain blade unit has the internal surface of close inboard, and above-mentioned protector has one and is positioned between two internal surfaces and can produces the shielding portion of bridging effect to this open space.
Effect of the present invention is, utilizes direct consubstantiality to take shape in protector on the top side of chain nodal plate group, can produce bridging effect to this open space, and it is good and effectively prevent effect such as foreign matter intrusion to allow integral body can reach structural strength.

Embodiment
The present invention is described in detail below in conjunction with drawings and Examples:
Before the present invention is described in detail, be noted that in the following description content similar elements is to represent with identical numbering.
As shown in Figure 3 and Figure 4, one first preferred embodiment of chain 2 of the present invention, this chain 2 comprise chain nodal plate group 21 that most headtotails are string, most in order to the bearing pin 22, that is connected in series this majority chain nodal plate group 21 by this majority long strip open space 23 that chain nodal plate group 21 matches and defines, and most respectively consubstantiality extend be arranged at this majority chain nodal plate group 21 a length on the top side and can be jointly to the protector 24 of these open space 23 generation bridging effects.This majority bearing pin 22 is to be placed in this open space 23 at interval.
Each chain nodal plate group 21 has the chain blade unit 20 that two-phase is faced, each chain blade unit 20 comprises contact pin 211 in one, an outer chain sheet 212, and one is arranged in this contact pin 211 on an inner face of this open space 23 and the most contiguous internal surface 201 of facing this chain blade unit 20.One end of this outer chain sheet 212 is stacked and placed on the end outer surface of contact pin 211 in this, and the other end of this outer chain sheet 212 then is to be stacked and placed on the end outer surface of interior contact pin 211 of adjacent another chain nodal plate group 21.And the interior contact pin 211 of each chain nodal plate group 21 is to see through several bearing pins 22 to be combined into one with outer chain sheet 212.In the present embodiment, the end face of this two outer chain sheet 212 is not contour.
Each protector 24 is that the square type level that is single is tabular, and be long to stretch out to top side consubstantiality level from one of the outer chain sheet 212 (apical side height junior) of corresponding this chain nodal plate group 21 of institute, and cross this in two contact pin 211 with bearing pin 22 tops and longly the locating to the top side is other of another outer chain sheet 212 (apical side height the higher person) that arrives.Wherein, each protector 24 have one be positioned at the shielding portion 240 of 201 of two internal surfaces of corresponding this link plate group 21, in order to, this protector 24 can cover the open place of going up of this open space 23.
Therefore, utilize the individual open place of going up of this open space 23 that is arranged in of this majority, and consubstantiality takes shape in the protector 24 on the outer chain sheet 212, the effect of screening that this open space 23 is produced, snap in or dust is long-pending invests in this open space 23 to prevent that effectively foreign matter from invading, and can keep off assemblies such as supporting contact pin 211 in external force collision or the false touch, outer chain sheet 212 and bearing pin 22, simultaneously, protector 24 can also be strengthened the structural strength of outer chain sheet 212, allow these chain 2 integral body can produce structural strength good, effectively prevent effects such as foreign matter is invaded, dustproof and impact resistance.
