Keywords and boolean syntax (USPTO or EPO format): seat belt searches these two words, or their plurals and close synonyms. "seat belt" searches this exact phrase, in order. -seat -belt searches for documents not containing either word.
For searches using boolean logic, the default operator is AND with left associativity. Note: this means safety OR seat belt is searched as (safety OR seat) AND belt. Each word automatically includes plurals and close synonyms. Adjacent words that are implicitly ANDed together, such as (safety belt), are treated as a phrase when generating synonyms.

Embodiment
Below in conjunction with the Figure of description in the utility model, the technical scheme in utility model is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment will be elaborated to a kind of cable seal structure, and the cable seal structure of the utility model embodiment is particularly useful for the cable in medicine equipment, and preferably, cable seal structure is for ultrasonic probe described in the present embodiment.Referring to Fig. 1, is the structure chart of described cable seal structure.Cable seal structure described in the present embodiment comprises:
Cable external protection 01, Connection Block 02, the collar 03 and be connected and fixed ring 04.
Wherein, cable external protection 01 is Elastic Cylindrical layer, inner hollow, and for the protection of the internal structure of cable, this internal structure is generally plain conductor.In the present embodiment, the materials and supplies feature of cable external protection 01 is not specifically limited.Connection Block 02 is for the end of device and the cable external protection 01 of connection device.The collar 03 is connected for further attached cable external protection 01 and Connection Block 02.Be connected and fixed ring 04 position for retaining collar 03.
Preferably, the cable seal structure described in the present embodiment can also comprise: sealing ring 05, the outer containment vessel 06 of device and protective sleeve 07.
Wherein, protective sleeve 07 is for slowing down the physical bend of cable external protection 01 end.The outer hard containment vessel of the device that the outer containment vessel 06 of device is equipment; internal structure for the protection of device; cable seal structure described in the present embodiment is arranged at outer containment vessel 06 inner chamber of device by major part; equipment described in the present embodiment can be supersonic diagnostic set; described device can be ultrasonic probe, and described cable seal structure can be for the handle part of ultrasonic probe.Sealing ring 05 is connected for the outer containment vessel 06 of tight connecting seat 02 and device.
Preferably, cable external protection 01, sealing ring 05, protective sleeve 07 are elastomeric material manufacture, Connection Block 02, the collar 03, are connected and fixed ring 04 for hard material manufacture, are generally metal material, and the outer containment vessel 06 of device is also hard material manufacture.
Refer to Fig. 2, Connection Block 02 is cylindrical, and its middle part arranges interior ring 021 and comprises the connecting cylinder 022 of through hole.The internal structure of cable, plain conductor can pass through the through hole of connecting cylinder 022.The inwall of interior ring 021 comprises internal thread.
In addition, the outer wall of Connection Block 02 comprises the groove 023 mating with sealing ring 05.
Preferably, the outer wall of connecting cylinder 022 is gradient wall, makes to be in connecting cylinder 022 profile the taper at the top of pruning.In the present embodiment, the outer wall of connecting cylinder 022 is 15 degree left and right.
Refer to Fig. 3, preferably, the inwall of the collar 03 is gradient wall.In the present embodiment, the outer wall of the collar 03 is 15 degree left and right.The outer wall of connecting cylinder 022 equates with the inwall gradient of the collar 03, makes can place and abundant extruded cable external protection 01 between the two.
In addition, the outer wall of the collar 03 comprises a projection circle 031, and the exradius of projection circle 031 is greater than the interior radius of circle that is connected and fixed ring 04, make to be connected and fixed ring 04 and can fully press projection circle 031, thus the position of retaining collar 03.
Refer to Fig. 4, the outer wall that is connected and fixed ring 04 comprises external screw thread.Be connected and fixed ring 04 external screw thread and mate with the internal thread of the inwall of interior ring 021, the two can be connected by bolt arrangement.
