Description
Technical field
The utility model relates to torsion spring technical fields, more particularly to a kind of torsion spring that can adjust spacing.
Background technique
A kind of patent of torsion spring is disclosed in existing Chinese patent database, number of patent application is
201620222171.3, patent application day is 2016.03.22, and license notification number is CN205423648U, and license is public
Announcement day is 2016.08.03, and structure includes the first spring body for being connected with the first link arm and the second spring for being connected with the second link arm
Body, first link arm are arranged and are slidably connected to the second link arm, and first link arm and the second link arm junction, which are equipped with, to be realized
The fixing piece that first spring body is fixedly connected with the second spring body.Disadvantage is that: the first link arm of first spring body and second
Second link arm of spring body is screwed on through screw thread, therefore reduces the intensity of torsion spring entirety, and when due to torsion spring work, torsional spring can be sent out
Raw rotation, the first spring body and the second spring body are easily separated, and torsion spring cannot reliably work.
Utility model content
The purpose of this utility model is in view of the deficienciess of the prior art, the easily opposite rotation of i.e. the first spring body and the second spring body
Turn, torsion spring is difficult to reliably work, the torsion spring for providing a kind of reliable operation, capable of adjusting spacing.
To achieve the goals above, the utility model one kind can adjust the technical solution that the torsion spring of spacing is taken:
A kind of torsion spring that can adjust spacing, includes the first torsional spring body and the second torsional spring body of coaxial arrangement, and first
First link arm of torsional spring body is disposed adjacent with the second link arm of the second torsional spring body, and the first link arm connects with the second link arm through connecting component
It is connected into U-shaped section with external components clamping, the connecting component includes tube body, is opened up on tube wall there are two along tube length
The open slot in direction, an open slot open end and one end face of tube body are connected, and another open slot open end connects with tube body other end
Logical, the equal bending of first link arm and the second link arm free end forms vertical section, and the first link arm sliding plug is in tube body one
In end, the vertical section of the first link arm is connected in an open slot, and the second link arm sliding plug is in the tube body other end, the second link arm
Vertical section be connected in another open slot.
When utility model works, the first torsional spring body and the second torsional spring body are socketed on peripheral hardware rod piece, make tube body,
Another link arm of another link arm of one torsional spring body and the second torsional spring body is connected on peripheral device, torsion spring work.
Compared with prior art, the utility model has the following beneficial effects: due to tube body presence, tube body is by the first torsional spring body
A torsion spring is connected into the second torsional spring body, and since open slot is matched with vertical section, it is ensured that the first link arm and second connects
Arm moves synchronously, it is ensured that torsion spring reliably works.
Two open slots are located in same horizontal line.
The first link arm vertical section and the equal bending of the second link arm vertical section form crotch, and the connecting component further includes having
Elastic rubber ring, the crotch of the first link arm and the crotch of the second link arm link into an integrated entity through elastic rubber ring.Elastic rubber ring is kept away
Exempt from the first link arm to slip from tube body with the second link arm.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein, 1 first torsional spring body, 101 first link arms, 2 second torsional spring bodies, 201 second link arms, 3 connecting components, 301 pipes
Body, 302 open slots, 303 elastic rubber rings, 4 be U-shaped section, 5 vertical sections, 6 crotches.
Specific embodiment
As described in Figure 1, the torsion spring of spacing can be adjusted for one kind, includes the first torsional spring body 1 and the of coaxial arrangement
Two torsional spring bodies 2, the first link arm 101 of the first torsional spring body 1 are disposed adjacent with the second link arm 201 of the second torsional spring body 2, the first link arm
101 and second link arm 201 through connecting component 3 connect into external components clamping U-shaped section 4, connecting component 3 include tube body 301,
It is opened up on 301 side wall of tube body there are two the open slot 302 along 301 length direction of tube body, two open slots 302 are located at same horizontal line
On, 302 open end of an open slot and 301 1 end face of tube body are connected, another 302 open end of open slot and 301 other end of tube body
It connects, the equal bending of the first link arm 101 and 201 free end of the second link arm forms vertical section 5, and 101 sliding plug of the first link arm is in pipe
In 301 one end of body, the vertical section 5 of the first link arm 101 is connected in an open slot 302, and 201 sliding plug of the second link arm is in tube body
