Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Present embodiment discloses a kind of articulated structures of chamber door, as shown in Figure 1 and Figure 2, including be fixed on chamber door first
Leaf of hinge 1, the second leaf of hinge 2, the hollow axial core 3 being fixed on cabinet, the second leaf of hinge 2 include the second page board 4, are welded in the
The upper ring 5 of two page boards, 4 side and lower ring 6；First leaf of hinge 1 includes the first page board 7 and is welded in 7 one middle side part of the first page board
Middle ring 8.Upper ring 5, middle ring 8, lower ring 6 are set gradually and axial line overlaps, and hollow axial core 3 is arranged in ring 5, middle ring 8
In lower ring 6, offered in hollow axial core 3 for be grounded across and diameter be greater than ground line axis hole 9.The diameter of axis hole 9 is big
In ground line, the abrasion between ground line and hollow axial core 3 can be reduced, and is worn convenient for ground line into hollow axial core 3.
As shown in Figure 2 and Figure 3,3 surface of hollow axial core offers the fixing port 10 for being through to axis hole 9, and fixing port 10 is arranged
In 3 middle section of hollow axial core corresponding with middle ring 8, and operation port 11 corresponding with fixing port 10 is offered in middle ring 8, operation port 11
It is hinged with fixing piece 12 on the side of the first page board 7, and fixing piece 12 is welded with buckle far from one end of the first page board 7
13, the card slots 14 with 13 cooperation of buckle are offered in middle ring 8.After ground line is passed through from axis hole 9, using fixing piece 12 to solid
The ground line determined in mouth 10 is fixed, and ground line is avoided to be pulled in chamber door moving process towards side and fixed point is caused to grind
Damage；The fixing piece 12 for recycling buckle 13 to be closed with 14 Duis of card slot is fixed, and enhances the fixed stably solidity of fixing piece 12, simultaneously
Prevent fixing piece 12 from falling off or losing.And fixing port 10 is set to the middle section of hollow axial core 3, make 12 earth wire of fixing piece
Middle section be fixed, thus make be grounded both ends stress equalization, avoid ground line there is the case where one end serious wear.
As shown in Figure 3, Figure 4, the section of fixing piece 12 is identical with 8 diameter of middle ring arc-shaped, arc-shaped center of circle court
To 11 direction of operation port, and fixing piece 12 is towards being fixed with several compact heaps 15 on the end face of operation port 11.Compact heap 15 totally six
Block does two rows of circumference array along the axial line of axis hole 9, and does three column arrays along the axial direction of axial line.Utilize what is circumferentially arranged
Compact heap 15 is grounded from multiple angular extrusions, so that ground line surface be made to be more uniformly stressed, prevents ground line from radially sending out
Raw displacement；And enable compact heap 15 that longer one section of ground line is fixed along axial array, it is difficult to ground line along axis
To being subjected to displacement, enhance fixed effect.
As shown in Figure 3, Figure 4, integrally formed with towards prolonging in operation port 11 on the axially disposed two sides of fixing piece 12
The position-limited edge 16 stretched.The fixing port 10 on hollow axial core 3 is limited using two position-limited edges 16, when fixing piece 12 is closed in lid
When operation port 11, position-limited edge 16 is moved and is withstood on to 11 direction of operation port on 10 edge of fixing port of hollow axial core 3, makes hollow shaft
Core 3 turns to the position that fixing port 10 is flushed with operation port 11, and can not rotate again, so that hollow axial core 3 be avoided to rotate
Influence the fixed effect of compact heap 15.
As shown in Fig. 2, 3 both ends of hollow axial core are threaded with an about collar 17 respectively, about along axis hole 9 on collar 17
Axial line offers the constrained port 18 that diameter is equal to ground connection linear diameter, and constrained port 18 is equipped with far from one end of hollow axial core 3 and prevents
Grind chamfering 19.It is constrained using the both ends of about 17 earth wire of collar, the both ends hair of ground line is driven when preventing chamber door from opening and closing
It is raw to swing, to reduce the abrasion between the both ends of ground line and hollow axial core 3, recycles abrasionproof chamfering 19 to be further reduced and connect
Abrasion between the both ends of ground wire and about collar 17.
The concrete operations process of the present embodiment is as follows:
Install ground line when, first two about collars 17 are removed, by one end of ground line sequentially pass through about collar 17, in
Empty central spindle 3, about collar 17；Then adjustment is grounded the length across hollow axial core 3 and adjusts the position of hollow axial core 3, then
Two about collars 17 are threadedly connected to the both ends of hollow axial core 3 respectively；Finally by the 12 lid closing operation mouth of fixing piece in middle ring 8
11, so that buckle 13 is passed through card slot 14 and the hook portion of buckle 13 is made to be fastened on 4 bottom of the second page board, thus using compact heap 15 to solid
The ground line middle section determined in mouth 10 is fixed, and be subjected to displacement ground line can not, reduces abrasion.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
