The invention relates to a rotating and fastening device of a round drum. The rotating and fastening device comprises a connecting plate, the round drum and a locking bolt, wherein the connecting plate is provided with two or more than two through holes; a rotating plate is provided with two or more than two thread holes; the locking bolt penetrates through the connecting plate and then is connected with the rotating plate in a fastening manner; the connecting plate is connected with the round drum; and the rotating plate is arranged in the round drum and is connected with the round drum. Threads are carved on the inner wall of the round drum; the rotating plate is connected with the round drum in a thread manner or convex steps are carved on the inner wall of the round drum; and the rotating plate and the round drum are connected in a step manner. The rotating and fastening device has the advantages that the continuous and rotary adjustment and fastening of the round drum is adopted, the rotary adjustment is easy, the fastening is reliable, and the locking is convenient.
Description
Technical field
The invention belongs to fastening-connecting device field, relate to a kind of cylinder rotary fixture, be particularly useful for rotation and regulate cylinder.
Background technique
Existing cylinder securing means mainly contains following several mode:
(1) flange fastening means: connecting plate is directly fixed by bolts on cylinder, this flange-type means of fixation, fastening reliable, but connecting plate rotation relative to cylinder can only be several fixing angles, and translation-angle is cumbersome, and connecting bolt need get loose.
(2) fastening means of profiled holes: this mode is fastening reliable, also continuous setup angle, the angular range rotating when adopting bolton is generally less than 180 degree, when adopting 4 bolts fixedly, angle of swing is generally less than 90 degree, and opened after irregularly-shaped hole, the mechanical strength of correlated parts can weaken, in the mechanical strength of this fastening means in many applications, can not satisfy the demand.
(3) outer clip fastening means: adopt the outer fastening means clamping, this fastening means can continuous unremitting adjusting angle of swing, but fastening fastness can't satisfy the demand in many places, and bolt easily exposes.
Summary of the invention
Problem to be solved by this invention is, overcome the deficiencies in the prior art, a kind of cylinder rotary fixture is provided, employing has two (or more than two) through holes on connecting plate, on swivel plate, there are two (or more than two) tapped holes, between swivel plate and cylinder, can relatively rotate, but not have relative sliding in the axial direction.When lock bolt is tightened, between connecting plate, swivel plate and cylinder, having enough large frictional force is enough to overcome the relative rotation between them, thereby reaches the object of fastening cylinder.When lock bolt unclamps, can make very easily again connecting plate, spiral plate produce relative rotation with cylinder, thereby reach the object that regulates cylinder angle of swing.
The present invention solves its technical problem and takes following technological scheme to realize:
According to a kind of cylinder rotary fixture provided by the invention, comprise connecting plate, cylinder and lock bolt, on described connecting plate, have two or more through holes, on swivel plate, have two or more tapped holes, lock bolt is fastenedly connected with swivel plate through after connecting plate, connecting plate is connected with cylinder, swivel plate is arranged in cylinder, on cylinder inner wall, there is screw thread, swivel plate is connected threadably with cylinder, or on cylinder inner wall, have protruding step, swivel plate is connected in step mode with cylinder.
The present invention compared with prior art has significant advantage and beneficial effect:
Of the present invention fastening effective, Installation Flexibility is high, easy to adjust, is that existing technology is irreplaceable, in the rotation adjusting of this type objects of cylinder, fastening applications, has peculiar advantage.Simple and ingenious structure of the present invention, installs easy to adjustly, makes full use of space and fastened object.
Described structure of the present invention, more easily seals processing, also easily meets the requirement of mechanical strength of total, and all parts are also than being easier to manufacturing.
The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to embodiment provided by the invention, structure, feature and effect thereof, be described in detail as follows.
A kind of cylinder rotary fixture as shown in Fig. 1～5, comprise connecting plate, cylinder and lock bolt, on described connecting plate 1, have two or more through holes 6, on swivel plate 4, have two or more tapped holes 7, lock bolt 3 is fastenedly connected with swivel plate through after connecting plate, utilize the housing of cylinder as fastening support, when tightening lock bolt, connecting plate, between swivel plate and cylinder, produce immense pressure, while attempting to rotate under the effect of cylinder in external force, frictional force between them is easy to be greater than 100kg power, therefore, general external force deficiency is so that cylinder rotation, when using general mode can not make connecting plate, when cylinder rotates relatively, just can think between connecting plate and cylinder it is fastening.Cylinder can regulate by relative uninterrupted continuous rotation with connecting plate, swivel plate.Connecting plate is connected with cylinder 2, and connecting plate can be end face with being connected of cylinder, the Placement of screw thread or step, swivel plate is arranged in cylinder, swivel plate is connected with cylinder, and swivel plate adopts screw thread or step with being connected of cylinder, in some specific occasion, can be also that end face connects.
When employing is threaded, the inwall of cylinder is carved with screw thread 8, when adopting step to connect, on the inwall of cylinder, be carved with protruding step 9, to guarantee when lock bolt is tightened, swivel plate can not produce axial movement, and whether connecting plate can rotate the state that depends on lock bolt relatively with cylinder with swivel plate.
Connecting plate can lengthen or be out of shape, and connecting plate, except fixing with cylinder, can also be connected connecting plate with other objects, thereby reach, cylinder is fixed on other objects or wall.Namely can rotate adjusting relative to other objects, and fastening, to meet different application needs.
Screw thread on lock bolt and cylinder adopts regular screw threads just can meet the requirement of fastening cylinder, if adopt other fine thread effects meetings better.
In the present invention, all involved component can adopt conventional manufacturing process to carry out processing, and the machining accuracy of mechanical parts used does not have specific (special) requirements, the precision of general process equipment can meet the demands, before Installation and Debugging, also without operator are carried out to complicated training, the installation personnel generally with machinery only need be read specification, just can correctly install, debug.
Connecting plate 1 leans against on the end face of cylinder 2 as shown in Figure 1, when unscrewing all lock bolts 3, just can be at an easy rate with respect to swivel plate 4 rotors, cylinder is rotated to after the angle needing, tighten again lock bolt 3, after tightening when tighting a bolt, under general External Force Acting, cylinder can not be rotated, so far, cylinder is fastening is installed to predetermined angle debugging rotation and has just completed.In the process of installation and angular adjustment, without using special-purpose instrument and equipment, operator are also without special procuring training.
Device of the present invention can be used widely in video monitoring equipment, for example, in Fig. 6, in cylinder, camera 5 can be installed, and when camera and cylinder are when fastening, rotor angle just can obtain the picture signal of different amount, just can meet different needs.
