The utility model relates to a novel cylinder rotating and fastening device. The cylinder rotating and fastening device comprises a connecting plate, a cylinder and locking bolts, wherein two or more through holes are formed in the connecting plate; two or more threaded holes are formed in a rotating plate; the locking bolts pass through the connecting plate and then are fastened with the rotating plate; the connecting plate is connected with the cylinder; the rotating plate is arranged in and connected with the cylinder; and a thread or a convex step is carved on the inner wall of the cylinder, and the rotating plate is connected with the cylinder through the thread or the step. The cylinder is continuously rotated, adjusted and fastened, easily rotated and adjusted, reliably fastened and conveniently locked.
Description
Technical field
The utility model belongs to and is fastenedly connected the device field, relates to a kind of novel cylinder rotation securing means, is particularly useful for the rotation adjusting cylinder.
Background technique
Existing cylinder securing means mainly contains following several kinds of modes:
(1) secure mode: connecting plate directly is fixed by bolts on the cylinder, and this flange-type means of fixation is fastening reliable, but the relative rotation of connecting plate and 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 adjust angle continuously; The angular range that when adopting bolton, rotates is generally less than 180 degree, and when adopting 4 bolt, angle of swing is generally less than 90 degree; And after having opened irregularly-shaped hole, the mechanical strength of correlated parts can weaken, the mechanical strength of this fastening means can not be satisfied the demand in many applications.
(3) clamp solid mode outward: adopt the outer fastening means that clamps, this fastening means can continuous unremitting adjusting angle of swing, but fastening fastness can't satisfy the demand in many places, and bolt exposes easily.
Summary of the invention
The utility model problem to be solved is; Overcome the deficiency of existing technology; A kind of novel cylinder rotation securing means is provided, is employed in (or more than the two) through hole that has two on the connecting plate, two (or more than two) tapped holes are arranged on the swivel plate; Can relatively rotate between swivel plate and the cylinder, but not have slide relative in the axial direction.When lock bolt was tightened, having enough big frictional force between connecting plate, swivel plate and cylinder was enough to overcome the relative rotation between them, thereby reached the purpose of fastening cylinder.When lock bolt unclamps, can make connecting plate, spiral plate and cylinder produce rotation relatively again very easily, thereby reach the purpose of regulating the cylinder angle of swing.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of novel cylinder that provides according to the utility model rotates securing means; Comprise connecting plate, cylinder and lock bolt, have two or more through holes on the described connecting plate, on swivel plate, have two or more tapped holes; Lock bolt is fastenedly connected with swivel plate after passing connecting plate; Connecting plate is connected with cylinder, and swivel plate is installed in the cylinder, and swivel plate is connected with cylinder.
It is to take following technological scheme further to realize that the utility model solves its technical problem:
Be carved with screw thread on the aforesaid cylinder inner wall, swivel plate is connected with engage thread with cylinder.
Be carved with protruding step on the aforesaid cylinder inner wall, swivel plate is connected with the step mode with cylinder.
The utility model compared with prior art has significant advantage and beneficial effect:
The utility model fastening effective, Installation Flexibility is high, and is easy to adjust, is that existing technology is irreplaceable, in the rotation adjusting of this type objects of cylinder, fastening applications, has peculiar advantage.The simple and ingenious structure of the utility model is installed easy to adjustly, makes full use of space and fastened object.
The said structure of the utility model is prone to seal processing, also is prone to satisfy the requirement of mechanical strength of total, and all parts are also than being easier to manufacturing.
The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to embodiment, structure, characteristic and the effect thereof that provides according to the utility model, specify as after.
A kind of novel cylinder rotation securing means shown in Fig. 1～5 comprises connecting plate, cylinder and lock bolt, has two or more through holes 6 on the described connecting plate 1; On swivel plate 4, have two or more tapped holes 7, lock bolt 3 is fastenedly connected with swivel plate after passing connecting plate, and the housing that utilizes cylinder is as fastening support; When tightening lock bolt; Produce immense pressure between connecting plate, swivel plate and cylinder, when attempting to rotate under the effect of cylinder in external force, the frictional force between them is easy to the power greater than 100kg; Therefore; General external force deficiency is so that the cylinder rotation when using general mode that connecting plate, cylinder are rotated relatively, just can think between connecting plate and cylinder it is fastening.Cylinder and connecting plate, swivel plate can uninterrupted relatively rotation adjusting continuously.Connecting plate is connected with cylinder 2, and connecting plate can be an end face with being connected of cylinder, the Placement of screw thread or step; Swivel plate is installed in the cylinder; Swivel plate is connected with cylinder, and swivel plate adopts screw thread or step with being connected of cylinder, also can be that end face connects in some specific occasions.
When employing is threaded; The inwall of cylinder is carved with screw thread 8; When adopting step to connect, be carved with protruding step 9 on the inwall of cylinder, to guarantee when lock bolt is tightened; Swivel plate can not produce axial moving, and whether connecting plate and swivel plate can rotate the state that depends on lock bolt with cylinder relatively.
Connecting plate can extend or be out of shape, and connecting plate can also link to each other connecting plate except fixing with cylinder with other objects, thereby reach cylinder is fixed on other objects or the wall.Just other objects are made rotation adjusting relatively, and fastening, to satisfy different application needs.
Screw thread on lock bolt and the cylinder adopts regular screw threads just can satisfy the requirement of fastening cylinder, if adopt other fine thread effects meetings better.
All involved component can both adopt conventional manufacturing process to carry out processing in the utility model; And the machining accuracy of used mechanical parts does not have specific (special) requirements; The precision of general process equipment can both meet the demands, and before Installation and Debugging, also need not operator are carried out complicated training; The installation personnel that generally has machinery only need be read specification, just can correctly install, debug.
Connecting plate 1 as shown in fig. 1 leans against on the end face of cylinder 2, when unscrewing all lock bolts 3, and just can be at an easy rate with respect to swivel plate 4 rotors; After cylinder being rotated to the angle of needs; Tighten lock bolt 3 again, after tightening when tighting a bolt, under general external force effect, can not cylinder be rotated; So far, cylinder is fastening is installed to predetermined angle debugging rotation and has just accomplished.In the process of installation and angular adjustment, need not to use special-purpose instrument and equipment, operator also need not to special procure training.
The device of the utility model can be used widely in video monitoring equipment, for example among Fig. 6, in cylinder, camera 5 can be installed, and when camera and cylinder were fastening, the rotor angle just can obtain the picture signal of different amount, just can satisfy different needs.
