As preferably, described internal surface of sleeve pipe is provided with a circle baffle ring II 1, and described bearing pin is provided with the screens step, and described elastic structure is the spring withstood between screens step and baffle ring II.
As preferably, described spring housing is located on bearing pin.
As preferably, described bearing pin comprises thick axle and the thin axle be connected with thick axle, and described screens step is formed by the joint of thick axle and thin axle.
As preferably, described bearing pin comprises body and is located at the snap ring on body, and described screens step is formed by snap ring itself.
As preferably, described body is provided with a circle groove, and described snap ring is the jump ring be positioned in groove.
As preferably, described sleeve pipe comprises pipe I and the pipe II of dock with the pipe I, and one on described pipe I inwall encloses the baffle ring I, and described snap ring is between baffle ring II and baffle ring I.
As preferably, described pipe I is docked with pipe II screw thread.
As preferably, be positioned at opposite direction one end that bearing pin pushed up from the sleeve pipe direction on described bearing pin and be provided with handle.
As preferably, described bearing pin is threaded with handle.
Beneficial effect:
The assembly type clamping pin structure that the utility model adopts technique scheme to provide, be provided with between sleeve pipe and bearing pin and have the elastic structure from sleeve pipe trend by the bearing pin top, can realize automatic screens, regulates easy to assembly, practical.
The accompanying drawing explanation
The sectional view that Fig. 1 is the utility model embodiment one;
The structural representation that Fig. 2 is the utility model embodiment one;
The sectional view that Fig. 3 is the utility model embodiment two;
The sectional view that Fig. 4 is the utility model embodiment three.
Embodiment
Embodiment one:
As illustrated in fig. 1 and 2, the assembly type clamping pin structure, comprise bearing pin 2 and be set in the outer sleeve pipe 1 of bearing pin 2, sleeve pipe 1 is all stretched out at the two ends of bearing pin 2, be provided with between described sleeve pipe 1 and bearing pin 2 and there is the elastic structure from sleeve pipe 1 trend by bearing pin 2 tops, be provided with between described sleeve pipe 1 and bearing pin 2 for preventing that bearing pin 2 breaks away from the disconnecting prevention structure of sleeve pipe 1.Described sleeve pipe 1 inwall is provided with a circle baffle ring II 121, and described bearing pin 2 is provided with screens step 21, and described elastic structure is the spring 3 withstood between screens step 21 and baffle ring II 121.Described spring 3 is set on bearing pin 2.Described bearing pin 2 comprises thick axle and the thin axle be connected with thick axle, and described screens step 21 is formed by the joint of thick axle and thin axle.Be positioned at bearing pin 2 on described bearing pin 2 and be provided with handle 4 by top from opposite direction one end of sleeve pipe 1 direction.Described bearing pin 2 is threaded with handle 4.This structure can be threaded connection while being connected with other mechanisms, and the screw thread now coordinated with worm structure in other mechanisms in the outer wall setting of sleeve pipe 1 gets final product.Pull handle 4, moving back to sleeve pipe 1 away from a handle end of 4 of bearing pin 2, unclamp handle 4, on the end top away from handle 4 of spring action lower bearing pin 2 from sleeve pipe 1.
Embodiment two:
With embodiment one difference, be as shown in Figure 3: described bearing pin 2 comprises body and be located at the snap ring on body, and body and snap ring are structure as a whole, and described screens step 21 is formed by snap ring itself.Described sleeve pipe 1 comprises pipe I 11 and the pipe II 12 of docking with pipe I 11, the circle of one on described pipe I 11 inwalls baffle ring I 111, and described snap ring is between baffle ring II 121 and baffle ring I 111.Described pipe I 11 is docked with pipe II 12 screw threads.This structure can be threaded connection while being connected with other mechanisms, and the screw thread now coordinated with worm structure in other mechanisms in the outer wall setting of pipe I 11 gets final product.During assembling, pipe I 11 is separated with pipe II 12, will manage I 11, spring and pipe II 12 opsition dependent relations and be set to respectively on bearing pin 2, tighten pipe I 11 and pipe II 12, then the handle 4 of screwing on gets final product.
Embodiment three:
As shown in Figure 4, with embodiment two difference, be: described body is provided with a circle groove, and described snap ring is the jump ring be positioned in groove.Compare embodiment two, in the present embodiment, bearing pin 2 is easy to make, fabricating cost is low.
