Abstract
The utility model provides a self-dismounted cover plate structure, which can be conveniently dismounted without auxiliary tools and the addition of an auxiliary structure. The self-dismounted cover plate structure comprises a cover plate and a plurality of dismounting bolts, the cover plate is provided with a plurality of through holes, and dismounting threads are tapped in the through holes; the threads of the dismounting bolts are matched with the dismounting threads. In the case of difficult dismounting, connecting bolts are dismounted, the dismounting bolts are screwed into the through holes by means of the dismounting threads to push a box type component on which the cover plate is mounted, and thereby the cover plate is dismounted. The self-dismounted cover plate structure is convenient to use, and man-hours can be saved; moreover, auxiliary tools, as well as the addition of an auxiliary structure, are not needed, so the manufacturing cost is saved; the cover plate and the box type component cannot be damaged as well, and the self-dismounted cover plate structure is safer and more reliable.
Description
Technical field
The utility model relates to Machine Design and manufactures field, relates in particular to a kind of from dismantling covering plate structure.
Background technology
Covering plate structure is extensively present in each field of Machine Design manufacturing, and Main Function is sealing, support and location etc.The modes such as general cover plate is used and is threaded, pin joint, welding or buckle connection are connected with casing class A of geometric unitA.Wherein be threaded because its standardization is high, connect reliably, be most widely used.In order to ensure good the playing a role of cover plate, conventionally require cover plate fully close be connected casing class A of geometric unitA and, sometimes also to take seal approach, as set up seal etc.Therefore, in inspection and maintenance process, in the time of need to dismantling cover plate, need first threaded connector to be unloaded, then apply external force and make cover plate separated with casing class A of geometric unitA, some cover plates are for some auxiliary structures of setting up for convenience detach, if handle, suspension ring etc., so increase the appearance and size that cost has strengthened again a whole set of machinery, and outstanding auxiliary body also likely affects the layout of other related components, increase trouble to design, assembling etc.If there is no supplementary structure, in the time of dismounting, external force is not easy to apply, if service time longer metal cover board, some places are corrosion, more not quick detachable, need to be by extracting tool, or the mode that adopts hammering, is easy to cover plate or other parts to damage.And cover plate has other interference mechanism around sometimes, there is no enough to launch and place the space of extracting tool, is more difficult to dismounting.
Utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of from dismantling covering plate structure, need, by aid, also not need to set up supplementary structure and just can dismantle easily.
Accordingly, the structure that the utility model adopts is: a kind of from dismantling covering plate structure, comprising:
One cover plate, has some through holes, and described through hole has been attacked dismounting screw thread;
Some demounting bolts, its screw thread matches with described dismounting screw thread.
Further, the quantity of described demounting bolt is less than or equal to number of openings.
Further, the ridge quantity of described demounting bolt is greater than the tooth number of dismounting screw thread.
Particularly, the ridge number of described demounting bolt is than the many 4-10 of tooth number of dismounting screw thread.
Further, also comprise the some connecting bolts corresponding with through hole, described connecting bolt is one by one through through hole.
Further, the Major Diam of described connecting bolt is less than the path of dismounting screw thread.
Particularly, the Major Diam of described connecting bolt is than the little 0.2-0.6mm of path of dismounting screw thread.
Further, described demounting bolt is full thread.
Further, described dismounting screw thread is coarse thread.
Further, the screw rod root of described connecting bolt is set with sealing gasket.
In the comparatively difficult occasion of dismounting, connecting bolt is pulled down, demounting bolt is threaded into through hole by dismounting, demounting bolt withstands the casing class A of geometric unitA with cover plate assembling, thereby detachable cover plate is got off.Easy to use, save man-hour; And need to or not to set up supplementary structure by aid yet, save production and processing cost; More can not damage cover plate and casing class A of geometric unitA, more safe, reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
In figure: 1-cover plate; 2-connecting bolt; 3-demounting bolt; 4-dismantles screw thread.
The specific embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate appended graphic being described in detail below.
Embodiment 1:
The covering plate structure of dismounting certainly as shown in Figure 1, it comprises: a cover plate 1, which is provided with some through holes, described through hole has been attacked dismounting screw thread 4; Some demounting bolts 3, its screw thread matches with described dismounting screw thread 4.Its ridge number is than many 4 of the tooth number of dismounting screw thread.Needn't all be furnished with demounting bolt 3 by each through hole.Also comprise the some connecting bolts 2 corresponding with through hole, described connecting bolt 2 is one by one through through hole.The Major Diam of described connecting bolt 2 is less than the path of dismounting screw thread 4.And there is the gap of 0.1mm.Cover plate 1 fits together by connecting bolt 2 and casing class A of geometric unitA (not shown), in the time of need to dismantling cover plate 1, connecting bolt 2 is pulled down, demounting bolt 3 is screwed in to all or part of through hole by dismounting screw thread 4, demounting bolt 3 withstands the casing class A of geometric unitA (not shown) with cover plate 1 assembling, thereby cover plate 1 is disassembled.Demounting bolt 3 is full thread coarse thread structure, has higher intensity, can carry dismounting resistance, and full thread structure can effectively guarantee effective use of demounting bolt 3.
Embodiment 2:
The covering plate structure of dismounting certainly as shown in Figure 1, it comprises: a cover plate 1, which is provided with some through holes, described through hole has been attacked dismounting screw thread 4; Some demounting bolts 3, its screw thread matches with described dismounting screw thread 4.Its ridge number is than many 10 of the tooth number of dismounting screw thread.Needn't all be furnished with demounting bolt 3 by each through hole.Also comprise the some connecting bolts 2 corresponding with through hole, described connecting bolt 2 is one by one through through hole.The Major Diam of described connecting bolt 2 is less than the path of dismounting screw thread 4.And there is the gap of 0.3mm.Cover plate 1 fits together by connecting bolt 2 and casing class A of geometric unitA (not shown), in the time of need to dismantling cover plate 1, connecting bolt 2 is pulled down, demounting bolt 3 is screwed in to all or part of through hole by dismounting screw thread 4, demounting bolt 3 withstands the casing class A of geometric unitA (not shown) with cover plate 1 assembling, thereby cover plate 1 is disassembled.Demounting bolt 3 is full thread coarse thread structure, has higher intensity, can carry dismounting resistance, and full thread structure can effectively guarantee effective use of demounting bolt 3.
