Abstract
The utility model relates to the technical field of chains, in particular to a rotary supporting thimble chain which comprises a chain and a supporting thimble on the side of the chain; the rotary supporting thimble chain is characterized in that the supporting thimble comprises a top part and a connecting part; the connecting part is provided with a connecting hole; the connecting hole is inserted on a thimble rotating shaft of the chain; the thimble rotating shaft is provided with a chain side plate used to movably limit the supporting thimble; the connecting part is provide with a vertical limiting boss and a horizontal limiting boss; the chain side plate is provided with a boss blocking hole; the rotary supporting thimble chain has simple structure and saves more space compared with the traditional chains; under external force, the cooperation of the vertical limiting boss, the horizontal limiting boss and the boss blocking hole can restrict the supporting thimble to be always horizontal or vertical, which better meets different requirements of reflow furnaces for chains in production.
Description
Technical field:
The utility model relates to the chain technical field, particularly rotatable support pin chain.
Background technology:
Be provided with the chain that is used to transmit pcb board in the reflow ovens that is used for the pcb board soldering of electronic components, on this chain, generally all be provided with support pin, be used for support pcb board.Support pin on the chain of existing reflow ovens all is to be fixedly installed on the side of chain with vertical form, this set exists following deficiency: because support pin is for fixedly installing, make it can't rotate adjusting, can only be in plumbness always, when not needing to use support pin aborning, then need whole link chain mechanism is moved to other position, this has not only wasted bigger space, simultaneously also make the function of chain and range of use be subjected to bigger restriction, do not satisfy the different requirements of reflow ovens chain.
The utility model content:
The purpose of this utility model be to provide at the deficiencies in the prior art a kind of simple in structure, can satisfy the rotatable support pin chain that reflow ovens requires the difference of chain.
For achieving the above object, the utility model adopts following technical scheme:
Rotatable support pin chain, the support pin that it comprises chain and is arranged on the chain side, it is characterized in that: described support pin includes pin top and connecting portion, be provided with connecting bore at described connecting portion, connect borehole jack and be inserted in the thimble rotating shaft on the chain, the thimble rotating shaft is provided with the chain strip side plate spacing to support pin realization activity; Connecting portion is provided with vertical positive stop lug boss and horizontal positive stop lug boss, and described chain strip side plate is provided with boss screens hole.
Between described support pin and chain, compression spring is installed.
The utility model beneficial effect is: it has adopted the support pin that comprises chain and be arranged on the chain side, it is characterized in that: described support pin includes pin top and connecting portion, be provided with connecting bore at described connecting portion, connect borehole jack and be inserted in the thimble rotating shaft on the chain, the thimble rotating shaft is provided with the chain strip side plate spacing to support pin realization activity; Connecting portion is provided with vertical positive stop lug boss and horizontal positive stop lug boss, described chain strip side plate is provided with boss screens hole, so a kind of chain of rotatable support pin, simple in structure, compare traditional chain and more save the space, under external force, by vertical positive stop lug boss, horizontal positive stop lug boss and can be restricted to support pin cooperating of boss screens hole and be in level or vertical two states all the time, better meet to produce and go up the different requirements of reflow ovens chain.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a birds-eye view of the present utility model;
Fig. 3 is the structural representation of the utility model support pin;
Fig. 4 is the structural representation that the utility model support pin cooperates with the chain strip side plate when being in plumbness;
Fig. 5 is the structural representation that the utility model support pin cooperates with the chain strip side plate when being in horizontality.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in Fig. 1 to 5, rotatable support pin chain, the support pin 2 that it comprises chain 1 and is arranged on chain 1 side, described support pin 2 includes pin top 3 and connecting portion 4, be provided with connecting bore 5 at described connecting portion 4, connecting bore 5 overlaps in the thimble rotating shaft 6 that is inserted on the chain 1, and thimble rotating shaft 6 is provided with the spacing chain strip side plate 7 of support pin 2 realization activities; Connecting portion 4 is provided with vertical positive stop lug boss 8 and horizontal positive stop lug boss 9, and described chain strip side plate 7 is provided with boss screens hole 10.Between described support pin 2 and chain 1 compression spring 11 is installed, this compression spring 11 can be so that support pin 2 be in the pretension state all the time.
In the chain transportation, when support pin 2 is in horizontality, horizontal positive stop lug boss 9 cooperates with boss screens hole 10 on the chain strip side plate 7, when the connecting portion 4 of support pin 2 is subjected to the power of A (see figure 5) direction, support pin 2 is around thimble rotating shaft 6 clickwises, be in the boss screens hole 10 until vertical positive stop lug boss 8, support pin 2 is in plumbness; When the pin top 3 of support pin 2 was subjected to the power of B (see figure 4) direction, support pin 2 was in the boss screens hole 10 until horizontal positive stop lug boss 9 around thimble rotating shaft 6 left-hand revolutions, and support pin 2 will be in horizontality this moment.Vertical positive stop lug boss 8, horizontal positive stop lug boss 9 and can be restricted to support pin 2 cooperating of boss screens hole 10 and be in level or vertical two states all the time, just can make it be in plumbness when in the production use of reality, needing to use support pin 2, not need to use support pin 2 and just can make it be in horizontality.Such structure setting has overcome the shortcoming that support pin 2 in the conventional chains can only be in plumbness, has both saved the space, also better meets to produce to go up the different requirements of reflow ovens to chain 1.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
