Furthermore, the top of handle is equipped with petal formula injection molding, petal formula injection molding and screw rod fixed connection.
The utility model discloses a theory of operation and beneficial effect as follows:
in this scheme, rivet the nut riveting on the bolt, round pin axle and jump ring are together fixed with round pin seat, bolt. The screw rod on the handle hangs in riveting the nut downthehole, and pin buckle and key seat are fixed respectively on the panel of difference, and the activity orbit hole of bolt is made a round trip to move about along the round pin axle, inserts the clockwise rotation handle in back in the pin buckle, and the distance that makes the handle go up the screw rod and stretch out the bolt through rotatory handle adjusts and tightly compels the panel dynamics.
The movable track hole of the bolt can move back and forth along the pin shaft, the bolt is locked when being inserted into the pin buckle, and the bolt is unlocked when being withdrawn from the pin buckle;
a screw rod on the handle is locked on the rivet nut, and the handle is rotated to enable the screw rod to extend out of the bolt to adjust the force for pressing the door panel;
this device is through riveting nut riveting on the bolt, and round pin axle and jump ring are together fixed with key seat, bolt, and the screw rod on the handle hangs in riveting the nut downthehole, and the pin is detained and the key seat is fixed respectively on the panel of difference, inserts bolt in the pin and detains back twist grip, makes the distance that the screw rod stretches out the bolt on the handle adjust the dynamics that sticiss the door plant through rotatory handle, reaches and satisfies the leakproofness requirement.
Drawings
Fig. 1 is a schematic structural view of an embodiment 1 of a compression type pressure door adjusting and locking device of the present invention;
fig. 2 is an exploded view of fig. 1.
Description of the drawings: the bolt comprises a pin boss 1, a bolt 2, a pin buckle 3, a pin shaft 4, a clamp spring 5, a rivet nut 6 and a handle 7.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.
In addition, the descriptions related to "first", "second", etc. in the present invention are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit ly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.
