Demand.In order to keep the support base 3 easy to disassemble, the both ends of the support base 3 are respectively equipped with self-locking grab 33, such as Fig. 4
Shown, specific structure is similar to the key ring with self-locking function.
Two connectors；
Specifically, two connectors are located at the two sides of wear-type fixing seat 1, the both ends of each connector
It is connect respectively with wear-type fixing seat 1 and support base 3, connector connects at the both ends of support base 3 with wear-type fixing seat 1 respectively
It connects, thus make support base 3 with the support of wear-type fixing seat 1, towing force needed for maxilla is lifted in acquisition.
The connector includes reel 5, and the reel 5 is rotatablely connected with the wear-type fixing seat 1；Non-return mechanism, such as
Shown in Fig. 2-3, the non-return mechanism is fixedly connected with the reel 5, for preventing 5 counter-rotating of reel.It is described non-return
Mechanism includes shell 28, single direction ratchet 6 and pawl 7, and shell 28 is wrapped in the outside of reel 5 and single direction ratchet 6, single direction ratchet
6 with the reel 5 is concentric is fixedly connected, one end of pawl 7 and single direction ratchet 6 are cooperatively connected, and offer via hole on shell 28
The other end of 8a, pawl 7 pass through the via hole 8a and are located at the outside of the via hole 8a, and pawl 7 is resisted against the hole wall of via hole 8a
So that via hole 8a provides thrust and prevents single direction ratchet 6 from reversing, the non-return mechanism further includes the portion of screwing 9, screws portion 9 and the list
It is fixedly connected to ratchet 6 is concentric；Traction rope 2, the upper end of the traction rope 2 is on the reel 5, the traction rope 2
Bottom end be provided with snap ring 21 compatible with self-locking grab 33, as shown in Figure 4.
When needing that support base 3 is adjusted, operator screws portion 9 towards assigned direction, screws portion 9 and drives volume
Cylinder 5 is rotated towards assigned direction, is wound to traction rope 2, makes the lifting support base 3 upwards of traction rope 2, to increase support base
3 pairs of maxillas lift dynamics.When the support base 3 to lift dynamics excessive, when needing to turn down, or unclamping the support base 3, behaviour
Author is applied to 7 one thrusts of pawl (as shown in figure 3, applying a downward thrust), disengages it from the beam to single direction ratchet 6
It ties up, loses the effect of non-return mechanism, reel 5 rotates backward, and extends traction rope 2, and then unclamp support base 3 to maxilla
Support.That is, by the setting of reel 5, traction rope 2 and non-return mechanism, it is right to allow the operator to easily to adjust support base 3
The size of maxilla towing force.
Further, in order to allow the operator to intuitively observe support base 3 to the size of the towing force of maxilla, it is described
Tractive force indicating mechanism 4 is provided on traction rope 2, specifically, as shown in Fig. 6, the tractive force indicating mechanism 4 includes hollow
The top of the shell 1 of tubular, shell 1 is fixedly connected with traction rope 2, and spring 42, spring 42 are provided in shell 1
Top be fixedly connected with shell 1, the bottom end of spring 42 is fixedly connected with traction rope 2, is offered on shell 1 axial
Strip through-hole 41a, the side of strip through-hole 41a is provided with tag line on shell 1, and pointer 43, pointer are fixed on spring 42
43 are limited in strip through-hole 41a, and can move along strip through-hole 41a.In use, traction rope 2 is equal to the pulling force of support base 3
The elastic force of spring 42, according to Hooke's law, the deflection of the elastic force and spring 42 of spring 42 is in a linear relationship, and the change of spring 42
Shape amount can intuitively be shown by the tag line of pointer 43 and the side strip through-hole 41a, so operator is according to pointer 43
Instruction can intuitively observe that traction rope 2 to the size of the pulling force of support base 3, and can intuitively observe support base 3
Whether the size of the pulling force of the traction rope 2 of two sides is equal, and then allows the operator to that size reasonable and equilibrium is arranged to support base 3
Towing force, guarantee support base 3 using effect.
The working principle of the utility model is that wear-type fixing seat 1 is first fixed on to the head of patient, regulate it is elastic,
The both ends of support base 3 are connect with the traction rope 2 of two sides again, suitable length respectively, support base 3 is placed into patient mouthful, slowly
Slowly the length of two sides traction rope 2 is tightened, passes through the pointer 43 in observation tractive force indicating mechanism 4 in adjustment process, guarantees to support
Seat 3 holding power it is suitable, and 3 two sides of support base power it is identical or difference within the allowable range.In addition, support base 3 makes
Reach certain time length with the time, when needing to be replaced progress cleaning and sterilizing, first passing through adjusting non-return mechanism keeps traction rope 2 appropriate
Elongation, mitigate support base 3 to the towing force of maxilla, then first another clean support base 3 be put into the mouth of patient, should
Support base 3 and old support base 3 are kept side by side, and the self-locking grab 33 at new 3 both ends of support base is respectively connected to two sides
On the snap ring 21 of 2 bottom end of traction rope, the self-locking grab 33 at old 3 both ends of support base and the connection of snap ring 21 are then released, it will be old
Support base 3 remove, then slowly tighten two sides traction rope 2 length, so that new support base 3 is substituted 3 pairs of old support base trouble
The maxilla of person is supported.
The utility model passes through the setting of reel 5, traction rope 2 and non-return mechanism, allows the operator to easily adjust
Support base 3 passes through the design of tractive force indicating mechanism 4 to the size of maxilla towing force, allows the operator to get information about
To the size of the pulling force of the traction rope 2 of two sides, the towing force of support base 3 is adjusted convenient for operator and guarantees support base 3 to maxilla
Towing force equilibrium.
The utility model is exemplarily described above, it is clear that the utility model implements not by aforesaid way
Limitation, as long as not using the method concept of the utility model and the improvement of various unsubstantialities that technical solution carries out, or not
It is improved that the conception and technical scheme of the utility model are directly applied into other occasions, in the protection model of the utility model
Within enclosing.The protection scope of the utility model should be determined by the scope of protection defined in the claims.
