Detailed Description
The utility model is further described below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the measuring tool of the present embodiment mainly includes a body 10, a detecting block 20, a spring assembly 30 and a no-go gauge 40.
Referring to fig. 2, the body 10 is provided with a receiving groove 11. Preferably, referring to the view direction of fig. 2, at least the front side or the rear side of the receiving groove 11 is open, or both sides are open, so as to form a structure penetrating from front to rear, so that the detecting block 20 can be inserted into the receiving groove 11 from the front side or the rear side, and similarly, the no-go gauge 40 can also be inserted from the front side or the rear side.
The right side of the body 10 is provided with an opening 12, so that the receiving groove 11 has a configuration with an open right side, and correspondingly, during detection, for example, the surgical knife rest 50 waits for a detection product to be inserted from the right side.
The receiving groove 11 may be divided into two portions including a first receiving space 11-a near the inner side and a second receiving space 11-b near the opening 12 side. It should be understood that, in the present embodiment, the first and second accommodating spaces 11-a and 11-b are not physically separated by a solid component, wherein:
the first accommodating space 11-a is mainly used for accommodating the detection block 20;
the second accommodating space 11-b is mainly used for placing the end to be detected of the surgical knife rest;
when the detecting block 20 moves, it can enter the second accommodating space 11-b. Furthermore, it should be understood that in the present embodiment, the boundary between the first and second accommodating spaces 11-a and 11-b is not strictly divided, but only two opposite portions constituting the accommodating groove 11.
After the surgical blade holder 50 is inserted, the spring assembly 30 pushes the detection block 20 and the surgical blade holder 50 upward and pushes the upper side of the surgical blade holder 50 against the top wall of the accommodation groove 11. In this case, a space is left between the bottom of the detection block 20 and the bottom wall of the housing groove 11, and the check gauge 40 can directly detect the object.
The sensing mass 20 is directly or indirectly engaged with the spring assembly 30. One end of the spring assembly 30 is connected to the body 10 or is held relatively fixed by a stopper mechanism.
When the detecting block 20 is pressed by an external force, the other end of the spring assembly 30 moves with the detecting block 20 directly or indirectly under the pressing action of the detecting block 20, so that the spring assembly 30 is compressed. At this time, the first receiving space 11-a above the receiving groove 11 is enough to allow the end of the surgical knife holder 50 to be tested.
When the external force applied to the detecting mass 20 is removed, the restoring force of the spring assembly 30 drives the detecting mass 20 to move upward. At this time, the spring assembly 30 tightly pushes the detection block 20 and the surgical knife holder 50 together, and the surgical knife holder 50 is pushed against the upper inner wall of the first accommodation space 11-a of the accommodation groove 11.
In the measuring device, the following geometrical relationships are evident, in the height direction in the view direction shown in fig. 1:
the upper inner wall of the first accommodating space 11-a, or a part of the inner wall of the first accommodating space is in contact with the surgical knife holder 50, and a point on the contact part of the upper inner wall and the local inner wall is selected as a reference point;
height D from the reference point to the lower inner wall of the second accommodating space 11-b of the accommodating groove 111The constant value is determined when the measuring gauge is manufactured, and is a constant value; similarly, the height of the detection block 20 is also a fixed value;
the upper end surface of the detection block 20 is in close contact with the bottom of the surgical knife holder 50, so that: the height from the reference point to the upper end face of the detection block 20 represents the width of the surgical knife rest 50 corresponding to the reference point, the width is determined by the specific surgical knife rest 50, and the widths of different surgical knife rests always have certain difference (corresponding tolerance), which is a variable for a measurement gauge; the sum of the width of the surgical knife holder 50 and the height of the detection block 20 is the height d2；
The height d of the space between the lower part of the detection block 20 and the bottom wall of the containing groove 11 is set to be empty1And said height d2The sum being the height D1。
It is assumed that, in the present embodiment, the height D is given as an example in natural units11, the standard of the width of the surgical knife holder 50 is 0.25 ± 0.05, and the height of the detection block 20 is 0.5, then the height d20.75 ± 0.05, correspondingly, the height d1＝0.25±0.05。
At this time, the height d is set1Adapted no-go gauge 40, which enables to detect said height d1Indirectly detecting whether the width of the surgical blade holder 50 is acceptable.
Further, a spring cavity 13 is disposed in the body 10 for accommodating the spring assembly 30. A pin hole 14 communicating the spring cavity 13 and the accommodating groove 11 is formed between the spring cavity and the accommodating groove for arranging a pin member 15, wherein: one end of the pin member 15 is disposed to abut against one end of the spring assembly 30, or both are connected together; the other end of the pin 15 is arranged to abut against said block 20, or, alternatively, is connected to the latter.
Preferably, the lower end of the pin member 15 has a wide width, and forms a stopper edge 150 protruding in a radial direction. The width of the pin hole 14 is smaller than the width of the lower end of the pin member 15 and slightly larger than the pin member 15. In this manner, the retaining rim 150 at the lower end of the pin member 15 is retained to one side of the pin hole 14. In the corresponding figure, when the restoring force of the spring assembly 30 acts on the pin member 15, the pin member 15 is not ejected upward.
Furthermore, the detecting block 20 is further provided with an operating pin, and the body 10 is further provided with a rotatable handle 16. The handle 16 may be coupled by any known rotational coupling, and the specific structure is not limited in this embodiment. The handle 16 may abut against an operating pin on the detection block 20 during rotation. Therefore, referring to the view direction shown in fig. 1, the handle 16 is rotated counterclockwise, the handle 16 presses on the operating pin to drop the detecting block 20 downward, and the space above the detecting block 20 is increased, so that the surgical knife rest can be put in; when the handle 16 is released, the spring assembly 30 returns and drives the detecting block 20 to move upwards.
The spring assembly 30 may be used to hold the test block 20 below it by the height d1。
Referring to fig. 3, the no-go gauge 40 includes a plurality of portions having different heights, including a first height portion 41, a second height portion 42, and a third height portion 43, which have successively lower heights. It is easily understood that the difference in height of adjacent height portions in the drawings is related to the tolerance range of the actual product and is small, and the difference in height is exaggerated in the drawings for clarity of illustration. In actual use, the person skilled in the art can customize the respective heights of the first height portion 41, the second height portion 42 and the third height portion 43 adaptively according to the relevant parameters of the product to be inspected.
The detection method is roughly as follows:
as described above, the upper limit of the width of the surgical blade holder 50 is set to 0.3, and accordinglyGround, said height d1The second height 42 of the no-go gauge 40 is 0.2, and at this time, the second height 42 of the no-go gauge 40 can be inserted into the empty space between the bottom of the detection block 20 and the bottom wall of the accommodation groove 11, and the first height 41 cannot pass through.
If the first height portion 41 can pass through, the height d will be described1Too large, where the width of the surgical blade holder 50 is too small; if the third height portion 43 cannot pass through, the height d will be described1Too small, in which case the width of the surgical blade holder 50 is too large.
In some embodiments, the no-go gauge 40 may also include only the first and second height portions 41, 42, with the third height portion 43 omitted; alternatively, in other embodiments, one skilled in the art may add more height sections as needed. Alternatively, the go-no go gauge 40 may be replaced with a plurality of independent go-no go gauges of different heights.
Referring to fig. 4, the no-go gauge 40 preferably has a symmetrical structure including two first height portions 41 at both end portions, a third height portion 43 at a middle portion, and two second height portions 42 between both end portions and the middle portion. When not in use, the third height portion 43 is also disposed in the space between the bottom of the accommodating groove 11 and the lower portion of the detecting block 20, so as to avoid the insertion of the no-go gauge 40 and improve the detecting efficiency.
As shown in fig. 5 and fig. 2, a first limiting portion 44 is disposed on the no-go gauge 40, and a first limiting groove 17 is disposed on a side wall of the accommodating groove 11 of the body 10, so that when the no-go gauge 40 is inserted from the front side or the rear side, the first limiting portion 44 is in limiting fit with the first limiting groove 17, and only the no-go gauge 40 is allowed to slide back and forth along the insertion direction.
Furthermore, a second limiting portion 22 is arranged on the detection block 20, a second limiting groove 18 is arranged on the side wall of the accommodating groove 11 of the body 10, and when the detection block 20 and the detection block are assembled together, the second limiting portion 22 can slide in the second limiting groove 18 when the detection block 20 moves up and down, and meanwhile, the detection block 20 can be prevented from sliding out upwards.
Fig. 6 shows a surgical blade carrier 50, which is provided with a sort of "U" -shaped opening 51 on the upper left side. For the surgical knife rest 50, one of the parameters to be detected is a height H from a circle center of the arc section 52 of the U-like opening 51 to a bottom surface thereof, and the detection method can be referred to, the detection block 20 is pressed down by the handle 16, the end to be detected of the surgical knife rest 50 is put in, the handle 16 is loosened to operate the no-go gauge 40, and the detection is very convenient. After the detection is completed, the handle 16 is pressed again, and the surgical knife holder 50 is taken out.
Correspondingly, a detection part 19 matched with the circular arc section 52 of the U-like opening 51 is arranged in the accommodating groove 11 of the body 10.
Obviously, the shape and position of the detection portion 19 can be adjusted to suit the product for different detection sites.
The embodiments of the present invention are illustrative only and should not be construed as limiting the scope of the claims, and other substantially equivalent alternatives that may be apparent to those skilled in the art are also within the scope of the utility model.
