As shown in fig. 8 and 9, the driving assembly may be the driving shaft 4, and the driving shaft 4 may also be a structural member in which at least one bushing is sleeved. When the driving component is the driving shaft 4, the movable body 22 is in direct contact with the driving shaft 4; when the driving shaft 4 is externally fitted with a sleeve, the movable body 22 is in direct contact with the sleeve. The present invention will be described by taking a drive assembly as an example of the drive shaft 4.
The "rotation circle" refers to an arbitrary circle in which the positioning sleeve 21 rotates about the center axis of the positioning sleeve 21.
The number of the inclined surfaces 21-1 is not limited, and is at least one, such as one, two, three, four, etc., however, in order to avoid the stress concentration of the driving assembly, the number of the inclined surfaces 21-1 is preferably more than two.
The rotating head is sleeved on a driving assembly to be assembled through the positioning sleeve 21, as shown in fig. 5, when the driving assembly is rotated to drive the movable body 22 to move towards the locking end, the movable body 22 is tightly clamped at the periphery of the driving assembly under the guidance of the inclined surface 21-1, so that the rotating head can be ensured to be locked and synchronously rotate with the driving assembly, the unidirectional locking of the rotating head is realized, and due to the existence of the locking force of the movable body 22, the rotating head can be ensured not to be separated from the driving assembly when rotating, the connection is reliable, and the use is safe.
When it is desired to remove the rotator head, as shown in fig. 6, the rotator head is rotated in reverse by a slight angle, for example, about 10 degrees, so that the movable body 22 moves toward the unlocking end to unlock the driving assembly, and at this time, the movable body 22 only contacts the driving assembly without any force, and only a small force is required to pull the rotator head out of the driving assembly; dismantle the convenience, be convenient for wash the rotating head, when the rotating head is installed once more to needs, only need with the direct plug bush of rotating head on drive assembly can, need not to confirm installation direction, simple to operate.
Furthermore, when the drive assembly is rotated in reverse through a slight angle, for example, around 10 degrees, it is also possible to unlock the swivel head, the unlocked swivel head remaining stationary and the drive assembly idling. For the use occasion that the reverse rotation of the rotating head needs to be limited, the one-way retaining member 2 can play a role in protecting the rotating head.
It is worth mentioning that as shown in fig. 1, the mounting sleeve 1, the one-way locking member 2 and the rotation executing member 3 form an assembly, and there is no relative movement between the three. The rotating head is disassembled and assembled together as a whole during disassembly and assembly, other redundant parts are not provided, the situation that one or more parts are forgotten is avoided, the disassembly and assembly are rapid, a disassembly and assembly tool is not needed, and a user does not need to check whether the disassembly and assembly are in place after the disassembly and assembly; and can be repeatedly disassembled and assembled. In addition, the structure is simple, and the processing cost is low.
In order to facilitate the installation of the movable body 22, a guide groove with the inclined surface 21-1 may be formed in the positioning sleeve 21, and the movable body 22 is located in the guide groove and can slide or roll along the guide groove.
Further, in order to reliably locate the movable body 22 in the guide groove, for example, a groove may be formed in the surface of the movable body, a guide projection matching the groove may be formed on the side wall of the guide groove, and the guide projection may be located in the groove of the movable body, and the movable body may reliably slide or roll in the guide groove by a limit action of the guide projection.
It should be noted that the inclined surface 21-1 is not limited to forming a guide groove, and other ways may be adopted as long as the movable body 22 can be ensured to slide or roll along the inclined surface 21-1.
Further, in order to ensure that the movable body 22 is more reliably mounted and does not fall off the positioning sleeve 21, the one-way locking member 2 further includes: the supporting frame (not shown in the figure) is arranged in the positioning sleeve 21, a movable channel of the movable body 22 is defined between the supporting frame and the inclined plane 21-1, the supporting frame is provided with an opening for exposing the movable body 22 out of the supporting frame, and the exposed end of the movable body 22 is used for contacting with the driving assembly. The movable body 22 is guided by the support frame and is kept in the positioning sleeve 21, the movable body and the inclined plane do not need to be additionally processed with a limiting structure, the structure is simple, the friction force is small, and therefore the heating value during working is relatively small.
In order to apply a distributed and uniform locking force to the outer periphery of the driving assembly, the inclined surface 21-1 comprises a plurality of inclined surfaces 21-1, the plurality of inclined surfaces 21-1 are distributed on the inner periphery of the positioning sleeve 21, the plurality of inclined surfaces 21-1 are preferably uniformly distributed on the inner periphery of the positioning sleeve 21, and the plurality of inclined surfaces 21-1 are inclined towards the same side.
Each of the movable bodies 22 is installed between each of the inclined surfaces 21-1 and the support frame by an elastic member, which may be a spring 21-2, and provides a restoring force to the movable body 22 by the elastic member, so that the movable body 22 regularly moves back and forth.
Specifically, the support frame is annular and coaxial with the positioning sleeve 21, and an opening for exposing the movable body 22 out of the support frame is arranged at the position corresponding to each movable body 22 on the support frame.
Specifically, the movable body 22 may be a roller pin, a rolling shaft, a rolling ball, or the like, or may be a sliding member having a sliding surface, where the movable body 22 slides in cooperation with the inclined surface 21-1 through the sliding surface, and the movable body 22 only needs to move along the inclined surface 21-1 to lock and unlock the driving assembly, and a specific type of the movable body 22 may be selected according to a specific application.
In addition, the material of the support frame needs to have good thermal conductivity, small friction factor, good wear resistance, strong impact toughness and a coefficient of linear expansion close to that of the movable body 22 besides a certain strength. The material of the support frame can be selected according to specific application occasions.
Specifically, the material of the support frame can be low-carbon steel/stainless steel, bakelite/plastic, brass/bronze/aluminum alloy and the like, and a suitable material can be selected according to specific use occasions.
It is worth mentioning that when the driving assembly drives the rotating head to rotate, the movable body 22 in the positioning sleeve 21 is always in contact with the circumferential direction of the driving assembly, so as to ensure no gap between the driving assembly and the positioning sleeve 21, thereby reducing the noise and vibration of the rotating head during rotation.
In short, when the rotary driving assembly drives the movable body 22 to roll or slide towards the locking end of the inclined surface 21-1, the movable body 22 is tightly held at the periphery of the driving assembly, as shown in fig. 5, so that the unidirectional locking of the unidirectional locking member 2 is realized, and the rotary head is driven to synchronously rotate. When the reverse rotation driving assembly drives the movable body 22 to roll or slide toward the unlocking end of the inclined surface 21-1, as shown in fig. 6, the one-way locking member 2 is in an unlocked state, and the driving assembly has no driving force to the rotary head, and the rotary head is not rotated at this time, and is used in a situation where the rotary head is allowed to rotate in one direction.
Further, in order to facilitate the installation of the elastic member, the one-way locker 2 further includes:
the mounting bracket 21-3, as shown in fig. 5 and 6, is located at the unlocking end of the inclined surface 21-1 and/or the supporting frame near each inclined surface 21-1, one end of the elastic member is connected to the mounting bracket 21-3, and the other end of the elastic member is connected to the movable body 22. As shown in fig. 6, the initial position of the movable body 22 can be maintained close to the unlocking end by the elastic member, so that when the rotary head is mounted again after being dismounted, the movable body 22 can be ensured to be in the unlocking position, and the rotary head can be smoothly sleeved on the driving assembly. The elastic member can also help the movable body 22 to be rapidly restored.
It should be noted here that the distance between the unlocking ends of the inclined surfaces 21-1 in the moving channel is greater than the diameter of the moving body 22, so that the moving body 22 has a moving allowance radially outward toward the positioning sleeve 21 at the unlocking end. So that the movable body can have a floating clearance when the drive assembly is inserted into the positioning sleeve 21, ensuring that the movable body does not squeeze the drive assembly.
Specifically, the mounting bracket 21-3 may be disposed on the inclined surface 21-1, for example, the mounting bracket 21-3 and the positioning sleeve 21 are integrally formed, or the mounting bracket 21-3 may be disposed on the supporting frame, for example, the mounting bracket 21-3 and the supporting frame are integrally formed, or one end of the mounting bracket 21-3 is connected to the inclined surface 21-1, and the other end is connected to the supporting frame; the installation manner of the mounting bracket 21-3 is not limited to the above-mentioned ones, and other connection manners such as inserting, clamping, adhering, etc. may be adopted with the inclined plane 21-1 and/or the supporting frame. The mounting bracket 21-3 may be in the form of a sheet, a block, a rod, etc., and the specific shape is not required as long as the mounting of the elastic member is facilitated.
In an embodiment of the present invention, the one-way locking member 2 may be a one-way bearing, an outer ring of the one-way bearing serves as the positioning sleeve 21, a rolling element serves as the movable body 22, and the holder serves as a supporting frame, which can also achieve the locking and unlocking effects of the one-way locking member 2 of the present invention.
In an embodiment of the present invention, in order to ensure that there is no relative displacement between the mounting sleeve 1 and the one-way locking member 2 after assembly and the mounting is convenient, the mounting hole 11 is configured as a non-circular hole or at least a section of non-circular hole, and the outer surface of the positioning sleeve 21 is configured to match with the non-circular hole.
Specifically, the non-circular hole may be a regular polygonal hole, such as a regular hexagonal hole, a regular octagonal hole, and the like, as shown in fig. 7, the outer surface of the positioning sleeve 21 may be a regular polygonal surface or at least one regular polygonal surface that is matched with the non-circular hole, such as a regular hexagonal surface, a regular octagonal surface, and the like, and the regular polygonal hole and the regular polygonal surface are selected, so that the positioning sleeve 21 and the mounting sleeve 1 are concentric, good stability after assembly of the positioning sleeve and the mounting sleeve is ensured, and the rotation is more stable.
