Embodiment
The invention provides a kind of for the connection locking device between two mutual sheathed tubing strings, this connection locking device is held the tubing string that is locked tightly by anchor ear section, during locking state, this connection locking device is larger to the area that the tubing string that is locked pushes, and locks more firm.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who obtains under the creative work prerequisite.
Please refer to Fig. 2, a kind of structural representation that connects locking device that Fig. 2 provides for the embodiment of the invention.The connection locking device that present embodiment provides, be used for two lockings between the mutual sheathed tubing string, comprise anchor ear section 1 and positioning part 2 two-part, described anchor ear section 1 is set in first and treats on the locking tube column outer wall, described positioning part 2 links to each other with described anchor ear section 1, is used for described anchor ear section 1 location and installation in the described second tubing string to be locked.When described anchor ear section 1 holds described the first tubing string to be locked tightly, can't produce relative displacement between the described first tubing string to be locked and the described anchor ear section 1, and described anchor ear section 1 by described positioning part 2 location and installation on the described second tubing string to be locked, therefore also can't produce relative displacement between the described first tubing string to be locked and the described second tubing string to be locked, pull is flexible mutually between two tubing strings, has namely realized the locking between two tubing strings to be locked.On the contrary, when described anchor ear section 1 loosens described the first tubing string to be locked, the described first tubing string to be locked can be in described anchor ear section between mobile and realization and the described second tubing string to be locked mutual pull, stretch.The hooping structure that utilization of the present invention is held tightly, squish area is larger has been realized the two mutually lockings between the sheathed tubing string with the structural principle of concision and compact more, and is easy to use, also is convenient to manufacture.
Please refer to Fig. 3-Fig. 6, a kind of structural representation when connecting locking device and being in locking state that Fig. 3 provides for the embodiment of the invention, Fig. 4 is the A-A face sectional view of structural representation shown in Figure 3, a kind of structural representation when connecting locking device and being in relaxation state that Fig. 5 provides for the embodiment of the invention, Fig. 6 is the B-B face sectional view of structural representation shown in Figure 5.
In the connection locking device that the invention described above embodiment provides, can be more simple and convenient for the operation of holding tightly, loosening that makes described anchor ear section, anchor ear section 1 specifically can comprise: sleeve part 101, the first locking end 102, the second locking end 103, cam part 3 and check lock lever 4.
Described sleeve part 101 is set in described first and treats on the locking tube column outer wall; Described the first locking end 102 and the second locking end 103 are extended along described sleeve part 101; Described check lock lever 4 comprises connecting rod 401, be arranged on the position-limited shaft 402 of an end of described connecting rod 401, and the other end that is arranged on described connecting rod 401, be used for described the second locking end 103 is carried out spacing positive stop end 403, described cam part 3 can be rotated around described position-limited shaft 402, and described cam part 3 matches with the exterior edge face of described the first locking end 102.
Its working principle is as follows: the setting because described cam part 3 matches with the exterior edge face of described the first locking end 102, when rotating described cam part 3, relative distance between described the first locking end 102 and affiliated the second locking end 103 will increase or diminish accordingly, thereby realizes that described sleeve part 101 loosens or holds the described first tubing string to be locked tightly.In order more to be convenient to realize the rotating operation to described cam part 3, can spanner 301 be set in described cam part 3, realize rotating operation to described cam part 3 by pulling described spanner 301, more simple and practical.Certainly, also not necessarily spanner 301 must be set at this, arrange some other structure that can realize described cam part 3 is carried out rotating operation also can, do not give unnecessary details in detail at this.
Can realize holding tightly or loosen described the first tubing string to be locked in order to guarantee described sleeve part 101, sleeve part 101 needs to use elastic material to make, but because materials limitations, its deformation recovery capability may decrease after using certain number of times, and then cause when loosening operation, sleeve part 101 can't return to relaxation state fully from locking state, affect its using effect, in order to avoid the generation of this kind situation as far as possible, in the connection locking device that the invention described above embodiment provides, can between described the first locking end 102 and the second locking end 103, spring 6 be set, utilize the auxiliary restitution of spring 6, guarantee that described sleeve part can revert to relaxation state from locking state better.More electedly, in order to prevent the deflection dislocation between two locking ends of described spring 6, affect using effect, can also be oppositely arranged spring card slot 5 at the interior edge face of described the first locking end 102 and the interior edge face of described the second locking end 103, and described spring 6 is arranged in the described spring card slot 5.
Please refer to Fig. 7, Fig. 8, Figure 11, wherein, the decomposition texture schematic representation of a kind of microphone holder that Fig. 7 provides for the embodiment of the invention, the structural representation of a kind of spanner that Fig. 8 provides for the embodiment of the invention, the structural representation of a kind of lateral connector that Fig. 9 provides for the embodiment of the invention, Figure 10 is the enlarged diagram of C part among Fig. 7, and Figure 11 is the enlarged diagram of D part among Fig. 7.
As shown in Figure 7, a kind of microphone holder that the embodiment of the invention provides comprises base 7, support tube 8, vertical connector 10.On the base 7 of described support tube 8 location and installation in location and installation in microphone holder, described support tube 8 comprises the first support tube 801 and the second support tube 802 two-part, and described the first support tube 801 and described the second support tube 802 are by described vertical connector 10 mutual sheathed connections.Described the first support tube 801 is the larger support tube of internal diameter in two support tubes, be that described the second support tube 802 is set in described the first support tube 802, any one connection locking device that described vertical connector 10 provides for the invention described above embodiment, and positioning part 2 location and installation of described vertical connector are on described the first support tube 801, and anchor ear section 1 is set on the outer wall of described the second support tube 802.By described vertical connector can realize between two support tubes locking with loosen, thereby can finish mutual pull or locking and positioning between two tubing strings, in the using process, as required, the user can lock tubing string 802 by pull described second selectively, and locks in place, thereby regulates the height of described microphone holder, simple to operate flexible, convenient and reliable.
Similarly, in the microphone holder that the invention described above provides, the positioning part 2 of its vertical connector 10 also can be set to hooping structure, further facilitates it is positioned operation, and can also realize the dismantled and assembled operation of described vertical connector 10, strengthen the flexibility of its use.
