Description
Technical field
The utility model relates to accelerator working service fields, more particularly, to one kind for the fixed support of Varian accelerator
The screw of frame.
Background technique
Currently, the screw on the interface arrangement of all accelerator types of Varian for mounting bracket is all one and protrudes from
Surface solid metal screw.So that clinical treatment teacher when executing the patient care plan of some partial centers, is easy accidentally to make to rotate
Rack and therapeutic bed bump against, and not only increase machine-spoiled rate it is also possible to making patient injury.And most of collision all occurs
On this raised screw.
Although Varian accelerator is mostly configured with laser collision avoidance system to reduce the probability to collide, due to setting
It counts defect and does not meet domestic use habit, this set system is abandoned by most clients.
Utility model content
The purpose of this utility model be exactly in order to overcome the problems of the above-mentioned prior art and provide it is a kind of for watt in
Pacify the screw of accelerator mounting bracket.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of screw for Varian accelerator mounting bracket, the screw include nut and screw rod, the screw rod packet
Integrally formed threaded portion, rotation section and head are included, the nut is hollow, the circular hole to be inserted into screw head is offered,
It is equipped with the first spring stop piece in head end, is equipped with second spring baffle, first spring catch in circular hole opening inner wall
A spring for being in tensional state is equipped between piece and second spring baffle.
First spring stop piece is embedded in the groove at head end outer rim.
The second spring baffle is embedded in the groove on circular hole opening inner wall.
First spring stop piece and second spring baffle is steel baffle.
The threaded portion is equipped with screw thread, and the screw thread accounts for the 4/5 of threaded portion total length.
The outer surface of the rotation section is circumferentially uniformly provided with multiple planes to rotate by spanner.
The lower surface of the nut is sticked and has fluorescence coating.
Compared with prior art, the utility model has the advantage that
One, the safety of accelerator is improved: reduction projection length (0.3-0.5mm or so is reduced to by original 1cm) drop
The low probability to collide, spring connecting structure is reduced to be damaged caused by collision, and fluorescence coating is coated with outside nut, is enhanced
Suggesting effect.
Two, high reliablity: pure mechanic structure, no electronic component, the product itself are without the risk to break down.
Three, using effect is good: improved purpose is enhancing safety, and the size and function of screw core are consistent with original.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the cross-sectional view of rotation section.
Description of symbols in figure:
1, nut, the 11, first spring stop piece, 21, threaded portion, 22, rotation section, 23, head, 231, second spring baffle,
3, spring.
Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
Embodiment
As shown in Figure 1, a kind of screw for Varian accelerator mounting bracket, the screw thread of the screw is upwards by Varian
Accelerator mounting bracket is fixed, including nut 1 and screw rod, and screw rod includes integrally formed threaded portion 21, rotation section 22 and head
23, nut 1 is hollow, offers the circular hole to be inserted into screw head 23, is equipped with the first spring stop piece 11, In in 23 bottom end of head
Circular hole opening inner wall is equipped with second spring baffle 231, is equipped at one between the first spring stop piece 11 and second spring baffle 231
In the spring 3 of tensional state, in normal state, nut 1 can be retracted by the pulling force of spring, so that the height of nut protrusion
Degree becomes smaller.
First spring stop piece 11 is embedded in the groove at 23 bottom end outer rim of head, and second spring baffle 231 is embedded in circle
In groove on the opening inner wall of hole, the first spring stop piece 11 and second spring baffle 231 are the arc-shaped baffle of steel.
Threaded portion 21 is equipped with screw thread, and screw thread accounts for the 4/5 of 21 total length of threaded portion, and its underpart reserves 1/5 position, to turn
The spanner in dynamic portion 22, which turns, reserves position.
The outer surface of rotation section 22 is circumferentially uniformly provided with multiple planes to rotate by spanner, as shown in Fig. 2, this
4 planes are opened up in example.
The lower surface of nut 1 is sticked and has fluorescence coating, convenient for prompting not touch in the environment of dark, it is ensured that safety.
The screw has a coil spring between breechblock and screw rod, usually when not in use since elastic force can make breechblock closer to machine
Device, need using when only need by bracket socket be aligned screw, make nut under the extruding of gravity and bracket itself socket
Reach normal position.
When the screw collides, since improved nut is no longer solid metal, it can fracture rapidly and be detached from machine,
Avoid more serious damage.
