Detailed description of the invention
With detailed description of the invention, this utility model is further illustrated below in conjunction with the accompanying drawings.
Shown in as shown in Figure 1 to Figure 4, compression spring installation tool described in the utility model, including the first slide block 1, second
Slide block 2, connection post 3, end plate 4 and nut 5, one end of connection post 3 is fixing with end plate 4 to be connected, and its other end is provided with thread segment 31,
Described thread segment is connected with nut 5 threaded engagement, and described first slide block 1 and the second slide block 2 are the most movably enclosed within connection post 3
On, and the first slide block 1 and the second slide block 2 are between nut 5 and end plate 4；First slide block 1 is provided with outward extending
First splenium 6, is provided with outward extending second splenium 7 on the second slide block 2, and described first splenium 6 and the second splenium 7 are mutual
Correspondence, and be spring rest area between the first splenium 6 and the second splenium 7.Wherein, thread segment 31 and nut 5 threaded engagement,
So that by the position of regulating nut 5, corresponding slide block can being applied axial compressive force, and then realize being placed into spring rest area
The compression of interior spring 10.Certainly, the length of thread segment 31 can be arranged as required to different length, it is possible at whole connection post 3
On be threaded, wherein, the preferably second slide block 2 has part be positioned at thread segment 31, has part to be then positioned at the company of smooth shell of column
Connect in post 3.
Compression spring installation tool described in the utility model, its use process is as follows: first by spring 10 to be compressed
It is placed into the spring rest area between the first splenium 6 and the second splenium 7 on the first slide block 1 and the second slide block 2, then by adjusting
Joint nut 5, makes the first splenium 6 and the second splenium 7 be compressed at spring 10 two ends, and orders about spring 10 and be compressed to appropriate length, so
After again by spring 10 together with this installation tool put into spring 10 need position to be mounted, afterwards reversely rotate nut 5 with
Unclamp the compression to spring 10, during this, by other structures in the installation site of spring 10, spring 10 two ends can be propped up,
And then the compression relation between the first slide block 1 and the second slide block 2 and spring 10 can be unclamped, the most i.e. can be taken off installation tool；Extremely
The installment work of this whole spring completes.
On the basis of said structure, in order to improve the first slide block 1 and guide effect of the second slide block 2, simultaneously, it is to avoid
In the case of being only provided with connection post 3, the problem that the first slide block 1 and the second slide block 2 are susceptible to reverse；This utility model enters
One step is provided with lead 8, and described lead 8 is parallel with connecting post 3, and one end of described lead 8 is fixing with end plate 4 to be connected,
Described first slide block 1 and the second slide block 2 are the most movably enclosed within lead 8.On the one hand the effect of lead 8 can improve cunning
The guide effect of block；On the other hand, it is possible to decrease the situation that slide block twists.
More specifically, above-mentioned be provided with lead 8 in the case of, due on lead 8 without arrange the company of being similar to
Connect the structure of thread segment 31 on post 3, thus on lead 8, graduation mark 12 can be provided with along its axial direction.Graduation mark is set
The benefit of 12 is the decrement knowing spring 10 that can be real-time during compression spring 10, thus can be real-time know spring
Whether 10 be compressed to desirable degree；So without additionally using survey tool, and then improve the effect to spring 10 compression process
Rate and degree of accuracy.
It addition, in above-mentioned two slide block (the i.e. first slide block and the second slide block), be located close to the slide block of end plate 4 side, its
Fixing with end plate 4 can connect or be structure as a whole in theory, i.e. this side slide is without moving along connection post 3.Such as, figure
Shown in 1, it is located close to end plate 4 side, when the second slide block 2 is the side away from end plate 4, can arrange when arranging the first slide block 1
First slide block 1 is fixing with end plate 4 to be connected or is structure as a whole.
Furthermore, it is contemplated that during compression spring 10, in order to reduce spring 10 two ends and the first splenium 6 or second
There is the phenomenon skidded in the contact surface of splenium 7, also can be provided with slipmat on the first splenium 6 and the second splenium 7 side in opposite directions
Layer 9.Wherein, so-called first splenium 6 and the second splenium 7 side in opposite directions, the needs both referred to and the side of 10 liang of end in contact of spring
Face, specifically can refer to shown in Fig. 1.Certainly, anti-skidding bed course 9 can use the material layer structures with certain skidproof effect, such as
Can be selected for as rubber antiskid layer.
It addition, for the ease of when spring 10 is installed to need position to be mounted, in installation site, corresponding other are tied
Spring 10 two ends can be propped up by structure, or typically can insert the structures such as lead in spring 10.Therefore this utility model enters one
Step take to arrange as follows: as shown in Fig. 2 to Fig. 4, described first splenium 6 and the second splenium 7 all include two spaced
Press strip, has the gap of width D between two press strips, and the size of described width D is consistent with the internal diameter H of spring 10.So-called wide
The size of degree D is consistent with the internal diameter H of spring 10, and the internal diameter H of the size of the width D referred to and spring 10 is substantially equal to the magnitudes, this
Sample, then can allow have lead to pass during assembling and pass from spring 10 inside, will not be affected by splenium simultaneously.It addition, from
The partial spring 10 that width D is exposed then can need other structures on position to be mounted to be propped up at its two ends, the most both by it
Can facilitate when unclamping nut 5 afterwards, take out whole installation tool.
It addition, as shown in Figures 3 and 4, in this utility model is provided with further on the first slide block 1 and the second slide block 2
Recessed U-lag 11, described first splenium 6 and the second splenium 7 inwall of U-lag 11 from the first slide block 1 and the second slide block 2 respectively
Extend outwardly, and there is step, so that exceeding the first pressure between the first splenium 6 and the second splenium 7 with corresponding U-lag 11
It is to be compressed that the internal face of the partial U-shape groove 11 of portion 6 and the second splenium 7 can and be placed between the first splenium 6 and the second splenium 7
The outer peripheral face corresponding matching at spring 10 two ends.Wherein, the benefit arranging U-lag 11 is: when spring 10 is placed into the first pressure
Time between portion 6 and the second splenium 7, firstly, since be provided with ledge structure, therefore, the placement location of spring 10 can be limited, it is to avoid
Its put into excess after be connected post 3 and interfere；Meanwhile, step originally as a part for U-lag 11, is therefore putting into spring 10
During, matched with the outer peripheral face at the two ends of spring 10 by the internal face of U-lag 11, can play spring 10 certain
Regulation of mental activities effect, and promote the placement location of spring 10 to be positioned at the extreme lower position of U-lag, make simultaneously spring 10 and the first splenium 6 and
Second splenium 7 is relatively placed in the middle, so, it is possible to decrease the first splenium 6 and the second splenium 7 skid during compression spring 10
Situation, the simultaneously the most more convenient subsequent installation to spring 10.It is furthermore preferred that this utility model arranges U-lag further
The cross section of 11 parabolically shape, and the minima of this parabolical radius of curvature L is not less than the half of the external diameter of spring；If
It is set to parabolic shape, it can be ensured that the spring 10 every time put into is respectively positioned on the centre position of U-lag 11.Certainly, as in Fig. 3 and Fig. 4
Shown in, should arrange accordingly the summit of parabolic U-lag 11 just with the first splenium 6 and interposition of the second splenium 7
Put correspondence.
