Description
Technical field
The utility model relates to a kind of hold down gag, a kind of bulb ball-bowl type pedestal pressing plate that can guarantee that thrust is vertical with base plate all the time of saying so especially.
Background technology
The pedestal pressing plate is a kind of hold down gag of being adopted when laboratory or actual engineering are used for the fixture of crimping regular shape (for example: tabular, cuboid, cylinder or the like) of being used for.Pedestal pressing plate of the prior art is made up of parts such as T shape wooden unit, screw rod, horizontal pressing plate, nut and backing plates usually; T shape piece is put into the groove on the base plate, be screwed into screw rod, add and the fixture backing plate of height such as grade basically; Again horizontal pressing plate is placed on backing plate and the fixture; Screw rod is passed from the hole of horizontal pressing plate, screw in nut then and tighten, reach the purpose that compresses fixture.Though the said base pressure plate structure can be fixed fixture; But owing to there is structural defective; So fixture compressed effect and unreliable; Reason is: because backing plate and fixture are difficult to reach just in time height such as grade, so when having difference in height between the two, use thin slice to adjust also and can have difference in height; Because being used for the horizontal pressing plate of crimping backing plate and fixture is rectangular shape,, cause the loosening of fixture then so when there were difference in height in backing plate and fixture, nut and horizontal pressing plate can not intactly be fitted, and can make screw rod tilted by side force.
For this reason, exigence those skilled in the art develop and aly can improve the novel pedestal pressing plate that crimping in the prior art is unreliable, do not allow to exist between backing plate and the fixture defectives such as difference in height.
The utility model content
In order to overcome defective in the prior art; The purpose of the utility model is to propose a kind of bulb ball-bowl type pedestal pressing plate that can reliably compress fixture; This pedestal pressing plate not only can compress fixture reliably, and what also allow backing plate and fixture exists certain altitude poor, easily adjustment.
The pedestal pressing plate of the utility model is realized through following technical scheme:
A kind of bulb ball-bowl type pedestal pressing plate comprises compressing member, nut, screw rod, backing plate, slide block, base plate and fixture, and said compressing member comprises hemisphere, be used to the leg that holds hemispheroidal ball bowl-type pedestal and be used for supporting base; Said base plate is provided with slideway; Said slide block along slideway move and this slide block in be provided with vertical installing hole; The bottom of screw rod is screwed in the installing hole of slide block, and make screw rod pass corresponding through hole on pedestal and the hemisphere successively, backing plate and the fixture that is located on the base plate carried out crimping through leg; Said nut screws in and tightens from the top of screw rod, so that fixture is compressed.
Wherein, the through hole on the said hemisphere is a straight hole, and the through hole on the said pedestal is last narrow, following wide tubaeform through hole.
Wherein, said slide block is for being inverted T shape structure, and said slideway is the inversion T shape slideway that adapts with the slide block shape.
Wherein, the installing hole inwall of said slide block is provided with internal thread, and the outer wall of said screw rod is provided with external screw thread, and said screw rod is threaded with the installing hole of slide block.
Wherein, the leg of said pedestal is at least three.
Wherein, be evenly equipped with three legs on the said pedestal, when a leg is crimped on the backing plate, two other leg is crimped on the fixture; When two legs are crimped on the backing plate, the another one leg is crimped on the fixture.
The beneficial effect of the utility model is:
This bulb ball-bowl type pedestal pressing plate is with ball bowl-type pedestal that has leg and hemisphere structure combining in the horizontal pressing plate alternative costs of the existing cuboid utility model; Because hemisphere can be realized universal connection in ball bowl-type pedestal; Even so exist certain altitude poor between backing plate and the fixture; Still can make hemispheroidal end face be in level, realize that promptly nut and hemispheroidal end face are in fastening fit-state all the time, and the assurance screw rod be accepted along axis direction all the time through the contact of adjustment hemisphere and pedestal; Not only adjustment easily, and can compress fixture reliably.

The specific embodiment
Below in conjunction with accompanying drawing the ball-and-socket bulb formula pedestal pressing plate of the utility model is done further detailed explanation.
As shown in Figure 1, the bulb ball-bowl type pedestal pressing plate of the utility model mainly comprises compressing member, nut 3, screw rod 4, backing plate 5, slide block 6, base plate 7 and fixture 8, and compressing member is made up of ball bowl-type pedestal 1, hemisphere 2 and the leg 9 that is used for supporting base.Be placed with the backing plate 5 and the fixture 8 that highly equate on the base plate 7; Base plate 7 is provided with inner concave shape slideway 10; Backing plate and fixture are positioned at the both sides of slideway; Being arranged with slide block 6 and slide block in the slideway 10 can move along slideway, and slide block 6 is for being inverted T shape structure, and the vertical section of slideway 10 also is the inversion T shape that adapts with slide block; Be provided with vertical installing hole in the slide block 6, the inwall of this installing hole is provided with internal thread, and the outer wall of screw rod 4 is provided with the external screw thread that the internal thread with installing hole adapts, and the bottom of screw rod 4 screws in the installing hole of slide block 6 and with slide block and is threaded.The center of the center of pedestal 1 and hemisphere 2 is respectively equipped with corresponding through hole; Make screw rod 4 pass the through hole on pedestal 1 and the hemisphere 2 successively and guarantee that hemisphere 2 places pedestal 1; Carry out crimping through backing plate on 9 pairs of base plates 7 of leg 5 and fixture 8 again, leg 9 is at least three, adopts three legs in this example; Can a leg be crimped on backing plate 5, in addition two legs are crimped on the fixture 8; Also can a leg be crimped on the fixture 8, two legs are crimped on the backing plate in addition, at last the top of nut from screw rod 4 screwed in and tightens, to guarantee reliably compressing fixture.
The backing plate 5 that the structure of the utility model can also allow to be positioned on the base plate 7 exists certain height poor with fixture 8, and as shown in Figure 2, fixture 8 is higher than backing plate 5 a little; In order to adjust the gradient of pedestal 1 more easily, the through hole on the hemisphere 2 is the identical straight hole of diameter up and down, and the through hole on the pedestal 1 is last narrow, wide tubaeform through hole down, and the upper shed diameter of through hole equates with through-hole aperture on the hemisphere 2 on the pedestal.This moment, whole syndeton was the same, only adjusted pedestal 1 and had certain gradient, but guarantee that all the time the end face of hemisphere 2 is in level; When the adjustment pedestal to gradient shown in Figure 2, and guarantee that leg 9 is crimped on backing plate 5 and got final product with 8 last times of fixture.
Adopt the pedestal pressing plate of the utility model structure,, can guarantee that also screw rod is stressed along its axis direction all the time, guarantee that promptly fixture can be compacted reliably even all exist certain height poor between three legs 9.
Should be noted that at last: above embodiment only in order to the explanation the utility model technical scheme but not to its restriction; In conjunction with the foregoing description the utility model is specified; Under the those of ordinary skill in field be to be understood that: those skilled in the art still can make amendment or are equal to replacement the specific embodiment of the utility model, but these modifications or change are all among the claim protection domain that application is awaited the reply.
