Abstract
The invention provides an assembled bayonet lock structure. The assembled bayonet lock structure comprises a pin roll and a sleeve which is arranged outside the pin roll in a sleeved mode, wherein an elastic structure which tends to jack the pin roll away from the sleeve is arranged between the sleeve and the pin roll, and a separation-prevention structure which is used for preventing the pin roll from being separated from the sleeve is arranged between the sleeve and the pin roll. The assembled bayonet lock structure can achieve automatic position clamping, and is convenient to adjust and assemble, and practical.
Description
Technical field
The present invention relates to a kind of assembly type bayonet lock structure.
Background technique
Existing bayonet lock mostly is an axle, must manually shaft extension be gone into by in the mechanism of screens when needing screens, when not needing screens, axle is pulled out by the mechanism of screens, and this structure screens operation is slower, screens automatically.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of assembly type bayonet lock structure, can realize automatic screens, and adjusting and assembling are all very convenient, practical.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: assembly type bayonet lock structure, comprise bearing pin and be set in the outer sleeve pipe of bearing pin, described draw together to be provided with between sleeve pipe and the bearing pin have the bearing pin top elastic structure from sleeve pipe trend, be provided with between described sleeve pipe and the bearing pin be used to preventing that bearing pin breaks away from the disconnecting prevention structure of sleeve pipe.
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 that withstands between screens step and the baffle ring II.
As preferably, described spring housing is located on the bearing pin.
As preferably, described bearing pin comprises thick axle and the thin axle that is connected with thick axle, and described screens step is formed by thick axle and thin joint.
As preferably, described bearing pin comprises body and is located at snap ring on the body that 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 that is positioned in the groove.
As preferably, described sleeve pipe comprises pipe I and the pipe II of dock with the pipe I, and one on the 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 the described bearing pin and be provided with handle.
As preferably, described bearing pin is threaded with handle.
Beneficial effect:
The assembly type bayonet lock structure that the present invention adopts technique scheme to provide is provided with between sleeve pipe and the bearing pin and has the bearing pin top elastic structure from sleeve pipe trend, can realize automatic screens, regulates easy to assembly, practical.

Fig. 3 is the sectional view of the embodiment of the invention two;
Fig. 4 is the sectional view of the embodiment of the invention three.
Embodiment
Embodiment one:
As illustrated in fig. 1 and 2, assembly type bayonet lock structure, comprise bearing pin 2 and the sleeve pipe 1 that is set in outside the bearing pin 2, sleeve pipe 1 is all stretched out at the two ends of bearing pin 2, described draw together to be provided with between sleeve pipe 1 and the bearing pin 2 have the elastic structure of bearing pin 2 top from sleeve pipe 1 trend, be provided with between described sleeve pipe 1 and the bearing pin 2 be used to preventing that bearing pin 2 breaks away from the disconnecting prevention structure of sleeve pipes 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 that withstands between screens step 21 and the baffle ring II 121.Described spring 3 is set on the bearing pin 2.Described bearing pin 2 comprises thick axle and the thin axle that is 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 the described bearing pin 2 and be provided with handle 4 by the top from opposite direction one end of sleeve pipe 1 direction.Described bearing pin 2 is threaded with handle 4.Can be by being threaded when this structure is connected with other mechanisms, get final product at the screw thread that the outer wall setting of sleeve pipe 1 cooperates with worm structure in other mechanisms this moment.Pulling handle 4, the end away from handle 4 of bearing pin 2 moves back to sleeve pipe 1, unclamps handle 4, spring action lower bearing pin 2 away from the end top of handle 4 from sleeve pipe 1.
Embodiment two:
Difference with embodiment one is as shown in Figure 3: described bearing pin 2 comprises body and the snap ring that is located on the 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.Can be by being threaded when this structure is connected with other mechanisms, get final product at the screw thread that the outer wall setting of pipe I 11 cooperates with worm structure in other mechanisms this moment.During assembling, pipe I 11 is separated with pipe II 12, will manage I 11, spring and pipe II 12 opsition dependents relation and be set to respectively on the bearing pin 2, tightens pipe I 11 and pipe II 12, and the handle 4 of screwing on again gets final product.
Embodiment three:
As shown in Figure 4, the difference with embodiment two is: described body is provided with a circle groove, and described snap ring is the jump ring that is positioned in the groove.Compare embodiment two, bearing pin is 2 easy to make in the present embodiment, fabricating cost is low.
