Technical field
The utility model belongs to mechanical equipment technical field, and the bearing pin otic placode that is used between the workpiece connects, and relates to a kind of self-locking bearing pin.
Background technique
In reality, workpiece generally adopts bolt to be connected with the bearing pin otic placode with Placement between the workpiece to be connected, and the bearing pin otic placode connects more general, and simple in structure, easy for installation.But in the bearing pin otic placode structure, come off from workpiece in order to prevent bearing pin, and safety pin is installed on bearing pin, because the influence of the external dimension of safety pin, so design bearing pin otic placode must be considered the installing space of safety pin when connecting.Simultaneously, when the bearing pin size is bigger than normal, the corresponding increase of the size of safety pin, specifications vary is big, and the difficulty that safety pin is installed just increases.
Summary of the invention
The purpose of the utility model provides a kind of self-locking bearing pin, and the specifications vary that has solved the existing technology safety pin is big, the corresponding increase of size, the problem that the difficulty of installation safety pin increases.
The technological scheme that the utility model adopted is; A kind of self-locking bearing pin, bearing pin body comprise pivot pin targeting part, pivot pin working portion and pivot pin stop portion, have the sleeve pipe mounting groove at pivot pin targeting part and pivot pin working portion intersection along circumference; The sleeve pipe mounting groove is equipped with sleeve pipe; In the sleeve pipe mounting groove, axially have spring mounting groove and fixture block mounting groove, be provided with Returnning spring in the spring mounting groove, be provided with fixture block in the fixture block mounting groove; Fixture block is pressed in the outer end of Returnning spring, and sleeve pipe is pressed on the fixture block.
The beneficial effect of the utility model is to compare with background technique, can bearing pin be penetrated workpiece hole after, accomplish the locking voluntarily of bearing pin through fixture block; When bearing pin will withdraw from workpiece; Through sliding sleeve, in the fixture block mounting groove of fixture block pressure pin axis body, guarantee that bearing pin withdraws from workpiece smoothly with sleeve pipe; This self-lock pin axle construction is simple, convenient operating maintenance.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
With reference to Fig. 1, Fig. 2, Fig. 3; The self-lock pin axle construction of the utility model is that bearing pin body 1 comprises pivot pin targeting part 5, pivot pin working portion 6 and pivot pin stop portion 7, has sleeve pipe mounting groove 14 at pivot pin targeting part 5 and pivot pin working portion 6 intersections along circumference; Sleeve pipe mounting groove 14 is equipped with sleeve pipe 2; In sleeve pipe mounting groove 14, axially have spring mounting groove 8 and fixture block mounting groove 9, be provided with Returnning spring 3 in the spring mounting groove 8, be provided with fixture block 4 in the fixture block mounting groove 9; Fixture block 4 is pressed in the outer end of Returnning spring 3, and sleeve pipe 2 is pressed on the fixture block 4.
In sleeve pipe mounting groove 14, axially have along two groups of spring mounting grooves 8 of diameter symmetry with along two groups of fixture block mounting grooves 9 of diameter symmetry
Returnning spring 3 is installed in the spring mounting groove 8 of bearing pin body 1, is used for accomplishing outside the resetting of fixture block 4; Sleeve pipe 2 can horizontally slip in the sleeve pipe mounting groove 14 on the axis body 1, and is limited in fixture block 4 in the fixture block mounting groove 9 of bearing pin body 1, prevents that fixture block 4 from coming off from bearing pin body 1.Fixture block 4 can be up and down in the fixture block mounting groove 9 of bearing pin body 1.Sleeve pipe 2 is divided into sleeve pipe 10,11 two semicircular ring parts of casing running; During mounting sleeve 2; Elder generation sleeve 2 top and the bottom are installed in the sleeve pipe mounting point of bearing pin body 1; Connecting plate 12 with arc connects into a full circle ring with screw 13 sleeve 2 in sleeve pipe mounting groove 14 again, also can be that alternate manner sleeve pipe 2 top and the bottom are connected in the bearing pin body 1, comprises riveted joint, welding etc.
When bearing pin will penetrate in the workpiece, sleeve 2 slided into bearing pin targeting part 5 one side of bearing pin body 1, guarantees that fixture block 4 stretches out; When bearing pin passes through workpiece hole; Workpiece hole guarantees bearing pin smoothly through workpiece hole, when bearing pin passes through workpiece hole smoothly in the fixture block mounting groove 9 of fixture block 4 pressure pin axis bodies 1; Fixture block 4 stretches out bearing pin body 1 again under the effect of Returnning spring 3, be used for limiting the bearing pin rollback and come off.When bearing pin will withdraw from the workpiece, sleeve 2 slided into bearing pin working portion one side of bearing pin body 1, in the fixture block mounting groove 9 of fixture block 4 pressure pin axis bodies 1, smoothly withdrawed from workpiece thereby accomplish bearing pin with sleeve pipe 2.
The releasing part that prevents of the utility model self-locking bearing pin is directly installed on the bearing pin; The installing space of bearing pin is unaffected, and it is easy easily that the setting of Returnning spring resets fixture block, and fixture block penetrates in the workpiece hole process at bearing pin; Workpiece hole is in the fixture block mounting groove of fixture block pressure pin axis body; Guarantee bearing pin smoothly through workpiece hole, fixture block is after bearing pin passes workpiece hole, and fixture block can reset through Returnning spring and accomplish the locking of bearing pin.When bearing pin withdraws from workpiece,, in the fixture block mounting groove of fixture block pressure pin axis body, guarantee that bearing pin withdraws from workpiece smoothly with sleeve pipe through sliding sleeve.
The advantage of the utility model comprises: 1) adopt integrative-structure to be convenient to install and deposit.2) bearing pin locking design reduces installing space on the bearing pin body.3) it is simple to operate that the design of fixture block and Returnning spring makes the self-locking of bearing pin, reliable.4) slide of sleeve pipe is simple, and is reliable.5) simple in structure, easy for installation, low cost of manufacture has good economic benefits and vast potential for future development.
