Detailed Description
In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the invention.
Example 1
Referring to fig. 1-4, the present embodiment provides a wave recorder with portable function, which includes a protection box 1, wherein the top of the protection box 1 is provided with an opening, and both sides of the top are rotatably installed with a closing plate 2, and the two closing plates 2 rotate along the side close to each other, so as to complete the closing function of the protection box 1, thereby protecting the wave recorder body 6 from being damaged by external influences.
The bottom fixed mounting of closure plate 2 has slope branch 21, and the inner chamber middle part of protection box 1 rotates through the pivot and installs two dwang 22 that the symmetry set up, through rotating closure plate 2, makes slope branch 21 take place to deflect for dwang 22 receives the extrusion force to take place to rotate.
In this embodiment, an included angle formed between the inclined supporting rod 21 and the closing plate 2 is an obtuse triangle, so that the distance between the end of the inclined supporting rod 21 contacting the rotating rod 22 and the rotating shaft is longer, and the rotating rod 22 is driven to rotate more labor-saving. In this embodiment, the one end that inclined strut 21 kept away from closure plate 2 is laminated with dwang 22 upper surface all the time, guarantees that inclined strut 21 provides the extrusion force to dwang 22 often.
Slidable mounting has sliding plate 7 in the inner chamber of protection box 1, and sliding plate 7 is located the top and the bottom and two dwang 22 swing joint of two dwang 22, and wave recorder body 6 is installed to the top of sliding plate 7, takes place to rotate through dwang 22, controls the lift of sliding plate 7 to when opening closure plate 2, make sliding plate 7 can go up and slide the outside that stretches out protection box 1, make things convenient for the manual work to take and operate.
In order to guarantee that dwang 22 can support sliding plate 7 all the time, the recess 71 that is used for installing dwang 22 is seted up to the bottom of sliding plate 7, recess 71 is inside to be seted up and to play limiting displacement's spacing groove 711 to dwang 22, the one end that dwang 22 and recess 71 contacted is rotated and is installed and spacing post 221 with spacing groove 711 assorted, spacing groove 711 and spacing post 221's cooperation is used, connect dwang 22 and sliding plate 7 into a whole, thereby guarantee that dwang 22 supports sliding plate 7 all the time, an approximate triangle-shaped stable structure has been formed between dwang 22 and the sliding plate 7 simultaneously, guarantee sliding plate 7's stability.
The mechanism for realizing the lifting function by adopting the lead screw and the worm in the prior art, for example, a portable recorder with the patent application number of CN202010865201.3 and a using method thereof, wherein the lifting function of the recorder body 6 is controlled by matching a plurality of lead screws and a plurality of worms, the structure is complex, the required acting force is large, the operation is time-consuming and labor-consuming, the lifting of the recorder body 6 can be completed only by matching the inclined supporting rod 21 and the rotating rod 22, the operation is very simple, and the lifting and the descending of the recorder body 6 can be completed only by turning over the closing plate 2.
In order to prolong the service life of dwang 22 and slope branch 21, the one end that slope branch 21 and dwang 22 contacted sets up to arc and outer wall cup joint flexible packing ring for slope branch 21 leaves certain buffering clearance between to dwang 22, avoids exerting oneself too big, leads to dwang 22 and slope branch 21 to break off.
In order to be better to the spacing effect of closure plate 2 to make when receiving external factors to influence, oscillograph body 6 can not be impaired, and telescopic link 3 is installed through the hinged-support rotation in the top of closure plate 2, and L type grafting piece 31 is installed through the axis of rotation to the one end that hinged-support was kept away from to telescopic link 3, and the inserting groove 13 that matches with L type grafting piece 31 is seted up to the both sides of protection box 1.
When needs carry on spacingly to closing plate 2, pulling telescopic link 3 for L type grafting piece 31 is pegged graft with inserting groove 13, and 3 inside of telescopic link are provided with and provide pulling force compression spring, receive the compression spring effect down, make L type grafting piece 31 better with inserting groove 13 grafting effect, accomplish spacingly to closing plate 2.
