Abstract
The utility model relates to a tripod technical field specifically discloses a tripod locking mechanism, including the underplate, three landing legs being connected with the underplate, every landing leg includes two lower riser that go up risers, are connected through locking mechanism and last riser, the handle that locking device includes cam, compact heap, stop pin, is connected with the cam, stop pin one end and cam contact, the other end inlay and insert on last riser, the compact heap is located the clearance department of the camshaft that is used for mounting cam and last riser, the spring is equipped with in the compact heap. The utility model has the advantages that, change former inserted tooth locking mechanism into by fitting pin location locking locking mechanism to increasing the tripod locking mechanism reliability and being convenient for the operability, whether locking mechanism needs earlier tensile landing leg by installing the spanner control on the cam with, and the action that struts the tripod again is irrelevant, and the riser that has caused because of the maloperation when having avoided using warp, has strengthened the convenient operation nature of product.
Description
Technical field
The utility model relates to tripod technical field, refers to a kind of tripod locking mechanism especially.
Background technique
The quadratic crank mechanism in Der Grundsatz der Maschinen has been used in the folding and unfolding of tripod, makes that tripod structure is compact, folding and unfolding is flexible, convenient and reliable.Locking in the past uses inserted tooth locking, its locking is locked by the tooth of the tooth occlusion lower standing tube of compact heap, therefore, tooth must coordinate with the position of tooth and puts in place, carrying out being engaged is the precondition of locking again, and tooth is corresponding with tooth position, lower standing tube must be stretched to the longest position (limit position), in actual use, easily there is misoperation in operator: when lower standing tube be not pulled to the longest position, strut tripod, make the tooth of compact heap extrude lower standing tube cylindrical wall by force, lower standing tube is extruded distortion.
Model utility content
The purpose of this utility model is to provide a kind of tripod locking mechanism, by spring bolt positioning and locking, is easy to operation.
To achieve these goals, the utility model have employed following technological scheme: a kind of tripod locking mechanism, comprise basal disc, three supporting legs be connected with basal disc, the lower standing tube that described every bar supporting leg is comprised two upper risers, is connected with upper riser by locking mechanism;
Described locking device comprises cam, compact heap, stop pin, the handle that is connected with cam;
Described stop pin one end and cam contact, the other end is intercalated on upper riser;
Described compact heap is positioned at the gap location for cams mounted camshaft and upper riser;
Described compact heap is built with spring.
Wherein, described camshaft top is connected with the rotating shaft for mounting handle.
Wherein, described compact heap is elastic material.
The beneficial effects of the utility model are: after adopting said structure, change into by the locking mechanism of spring bolt positioning and locking, to increase tripod locking mechanism reliability and convenient operation by former inserted tooth locking mechanism.The improvement of this locking mechanism, locking mechanism is controlled by the spanner be arranged on cam, and the need of first elongated leg, then the action strutting tripod has nothing to do, and the tubing distortion because of misoperation when avoiding use, enhances the operation convenience of product.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment technological scheme, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only that the utility model is in order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, below the accompanying drawing used required in p-embodiment or description of the prior art is briefly described, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the schematic perspective view of tripod;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is inserted tooth locking mechanism schematic diagram.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of tripod locking mechanism as shown in Fig. 1 ~ 2, comprises basal disc 1, three supporting legs be connected with basal disc 1, the lower standing tube 3 that described every bar supporting leg is comprised two upper risers 2, is connected with upper riser 2 by locking mechanism 4; Described locking device comprises cam, compact heap 9, stop pin 6, the handle 5 that is connected with cam; Described stop pin 6 one end and cam contact, the other end is intercalated on upper riser 2; Described compact heap 9 is positioned at for the gap location of cams mounted camshaft 7 with upper riser 2; Described compact heap 9 is built with spring 10; Described camshaft 7 top is connected with the rotating shaft 8 for mounting handle 5.
Rotatable handle 5, rotating shaft 8 drives cam axle and then band moving cam to rotate, when the direction that cam diameter is large is rotated to time identical with spring bolt horizontal position, spring 10 shrinks, cam is subject to the pressure of spring 10, and lower standing tube 3 is connected with cam, makes lower standing tube 3 connect reliably; When needs unclamp upper lower standing tube 3, rotatable handle 5 makes cam rotate, and the distance between cam and upper riser 2 becomes greatly, automatically will unclamp.
Inserted tooth locking mechanism as shown in Figure 3, locking uses inserted tooth locking, its locking is that the tooth of pressured closed-bite maloccllusion lower standing tube 3 is locked, therefore, tooth must coordinate with the position of tooth and puts in place, entering is the precondition of locking again, and tooth is corresponding with tooth position, lower standing tube 3 must be stretched to the longest position (limit position), actual using, easily there is misoperation in operator: when lower standing tube 3 be not pulled to the longest position, strut tripod, make the tooth of compact heap extrude lower standing tube 3 cylindrical wall by force, lower standing tube 3 is extruded distortion.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
