Abstract
The utility model discloses a novel locking and connecting structure of photographic equipment, which comprises a set screw and a plane bearing, the plane bearing is sleeved on the set screw and arranged above the screw head of the set screw, the fastening screw is connected to the second structural member through the first structural member in a threaded manner, when in use, the first structural member is arranged above the second structural member, the lower surface of the first structural member is provided with a plane bearing, the fastening screw passes through the plane bearing and the first structural member and is arranged on the second structural member through threads, the screw head of the fastening screw is contacted with the plane bearing, when the second structural member drives the fastening screw to rotate, the first structural member and the second structural member move relatively through two faces of the plane bearing, so that the friction force between the fastening screw and the first structural member is reduced, and the phenomenon of follow-up rotation between the fastening screw and the first structural member to cause screw tooth loosening is avoided.
Description
Technical Field
The utility model relates to a photographic equipment technical field specifically is a novel photographic equipment locking connection structure.
Background
Photographic equipment is a generic term for cameras, lenses and their associated accessories, various devices and articles related to photographic activities. Consumables including film and photographic shoulders, camera bags, etc. operated by most camera operators are in the category of camera equipment, and many cameras or accessories are often assembled and fixed together by a camera operator during a photographic activity. The fixing and locking mode of the existing photographic equipment has the following problems that friction exists between a fastening screw and a clamping surface to cause locking force; when the equipment moves relatively under the action of external force, the equipment drives the fastening screw to rotate along with the fastening screw, so that the equipment is loosened.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel photographic equipment locks connection structure, first structure below is provided with planar bearing, has reduced the frictional force between first structure and the holding screw, has avoided leading to holding screw to remove with first structure through the friction between holding screw and the first structure in order to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a novel photographic equipment locking connection structure: including holding screw and flat bearing, its characterized in that: the plane bearing is sleeved on the fastening screw, the plane bearing is arranged above the screw head of the fastening screw, the fastening screw is connected to the second structural member through the first structural member in a threaded mode, the first structural member is provided with a through hole, and the second structural member is provided with a threaded hole.
Preferably, the plane bearing is a flat-bottom ring type one-way plane thrust ball bearing.
Preferably, the diameter of the through hole of the first structural member is equal to the major diameter of the threaded hole of the second structural member.
Preferably, the outer diameter of the head of the set screw is larger than the outer diameter of the flat bearing, and the bottom flat surface of the first structural member is larger than the outer diameter of the flat bearing.
Preferably, the through hole of the first structural member, the flat bearing and the set screw are arranged in a coaxial relationship when assembled.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses first structure below is provided with flat bearing, has reduced the frictional force between first structure and the holding screw, has reduced the degree of difficulty of holding screw locking, has avoided leading to holding screw to remove along with first structure through the friction between holding screw and the first structure.
Drawings
Fig. 1 is a schematic diagram of the explosion structure of the present invention;
in the figure: 1. tightening the screw; 2. a flat bearing; 3. a first structural member; 4. a second structural member.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: a novel camera equipment locking connection structure comprises a fastening screw 1 and a plane bearing 2, wherein the outer diameter of the head of the fastening screw 1 is larger than that of the plane bearing 2, meanwhile, the bottom plane of a first structural member 3 is larger than that of the plane bearing 2, so that an operator can conveniently install the camera equipment through two modes of manual operation and tools, the applicability is improved, the plane bearing 2 is sleeved on the fastening screw 1, the plane bearing 2 adopts a flat-base ring type unidirectional plane thrust ball bearing, the service life of the plane bearing 2 is prolonged, the plane bearing 2 is arranged above the head of the fastening screw 1, the friction force between the fastening screw 1 and the first structural member 3 is reduced, the fastening screw 1 is connected to a second structural member 4 through the first structural member 3 in a threaded manner, the first structural member 3 is connected with the second structural member 4, a through hole is formed in the first structural member 3, a threaded hole is formed in the second structural member 4, the diameter of the through hole of the first structural member 3 is equal to the major diameter of the threaded hole of the second structural member 4, the through hole is prevented from interfering the installation of the set screw 1, and during assembly, the through hole of the first structural member 3, the plane bearing 2 and the set screw 1 are arranged in a coaxial relation, so that the installation is prevented from deviating.
The working principle is as follows: during the use, install first structure 3 in the top of second structure 4, the lower surface of first structure 3 is provided with flat bearing 2, pass flat bearing 2 and first structure 3 through holding screw 1, install on the second structure through the screw thread, the spiral shell head and the flat bearing 2 contact of holding screw 1, the not hard up condition of holding screw 1 avoids appearing, when second structure 4 drives holding screw 1 and rotates, make first structure 3 and second structure 4 relative motion through two faces of flat bearing 2, the frictional force of holding screw 1 with first structure has been reduced, it is not hard up to avoid holding screw 1 and first structure 3 to appear following the phenomenon and take place the thread to become flexible.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
