Abstract
The utility model relates to a connection locking structure for a movable connection rod, which is characterized in that one side of the connection rod is connected with a connector through a threaded shaft, and the other side of the connection rod is provided with a decoration endshield. When in use, the connector is connected with the connection rod through the threaded shaft. The connection rod is provided with a decorative anti-rotation connector, and the decorative connector is embedded into the connector end. The connection locking structure has simple structure and reliable connection, and is free from having the relative movement through the connection of the threaded shaft, so the thread is free from loosening. At the same time, a first anti-abrasion plastic sheet is arranged between the connection rod and the connector, and a second anti-abrasion plastic sheet is arranged between the connection rod and the decorative connector, so the plastic friction sheet can reduce the friction force between the connection rod and the connector so as to favor the movement of the connection rod.
Description
Technical field:
The technical field that the utility model relates to, specifically a kind of connection anti-loose structure that is used for movable rod, the connecting rod that is particularly suitable in the little space connects.
Background technique:
The connection of linkage mechanism is one of important and crucial research topic of mechanical field always, and the characteristics such as simple, compact, durable, reliable, easy to process of linkage structure are to weigh the important indicator of quality of connection.At present all there is the deficiency of some aspect in the connecting rod linkage structure of application, and some is that structure is too complicated, and some then is to connect unreliablely, and other has some then is to take up room greatlyyer, and should not be used for the outward appearance product.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved connection anti-loose structure that is used for movable rod, and it is too complicated that it can overcome in the prior art structure, and it is unreliable to connect, and bigger some shortcomings take up room.
To achieve these goals, the technical solution of the utility model is: a kind of connection anti-loose structure that is used for movable rod, it mainly comprises connecting rod and the connecting head that links to each other with connecting rod, it is characterized in that: link to each other by thread spindle between a side of connecting rod and the connecting head, the opposite side of connecting rod is provided with the decoration headkerchief.
During use, connecting head of the present utility model is connected on the connecting rod by thread spindle.Leave ornamental swirel on the connecting rod, decorative joint embeds tip side.This is simple in structure, connects reliably, connects the screw pair that adopts and does not have relative movement, so screw thread can not become flexible.Simultaneously be provided with the first wear-resistant plastic sheet between connecting rod and connecting head, be provided with the second wear-resistant plastic sheet between connecting rod and the decorative joint, above-mentioned plastic friction sheet can reduce the frictional force between connecting rod and the joint, is beneficial to link motion.
Description of drawings:
Fig. 1 is the utility model one embodiment's a structural representation
Fig. 2 is an A-A sectional view among Fig. 1
Fig. 3 is the structural representation of U type draw-in groove on the connecting rod of the present utility model
Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises connecting rod 2 and the connecting head 1 that links to each other with connecting rod, and its difference with the prior art is: link to each other by thread spindle 6 between a side of connecting rod and the connecting head, the opposite side of connecting rod is provided with decorates headkerchief 3.The inboard of decorating headkerchief is provided with tapped blind hole, and connecting rod is provided with U type draw-in groove 7, and an end of decorating headkerchief is provided with the projection that matches with U type draw-in groove.Be provided with the first wear-resistant plastic sheet 4 between connecting rod and the connecting head, be provided with the second wear-resistant plastic sheet 5 between connecting rod and the decorative joint.
In force, connecting head 1 links to each other with connecting rod 2 by thread spindle 6.Connecting rod 2 can be around the rotation of the rotating center of thread spindle 6 and running shaft keeps motionless, so connecting rod is when rotating, and thread spindle can transfer or had relative movement, has so just guaranteed that the connection of screw pair can not become flexible.Reliability in order to guarantee to connect adopts linkage structure shown in Figure 2 for this reason.Decorate the headkerchief 3 inboard tapped blind hole forms that adopt, the outside then is used for the concordant headkerchief of connecting rod 2, and is concordant with connecting rod on the surface like this, not only saved the space, and appearance looks elegant.When connecting rod rotates, between connecting head 1 and the connecting rod 2 and connecting rod 2 have relative movement with the surface of contact of decorating headkerchief 3, in order to reduce the friction between the surface of contact, increasing by the first wear-resistant plastic sheet 4 and the second wear-resistant plastic sheet 5 respectively between connecting head 1 and the connecting rod 2 and between connecting rod 2 and the decoration headkerchief 3.
Cause when preventing connecting rod 2 rotation and decorate headkerchief 3 and thread spindle 6 transfers or relatively rotate, be threaded looseningly thereby make, increase projection in a side of decorating headkerchief 3, this projection embeds in assembling the U type draw-in groove of connecting head 1 (referring to Fig. 3).So just prevented that decoration headkerchief 3 and thread spindle 6 existence from relatively rotating, screw thread just can not become flexible.
