Description
Technical Field
The utility model relates to a take-up technical field, more specifically say, relate to a compact small and exquisite spring take-up.
Background
When assembling the plastic mould, because be connected with the spring between template carrier plate and the thimble board, when other parts on the dismouting thimble board, need tighten up the thimble board earlier, tighten up through C shape pincers at present mostly. The mode is that C shape pincers are itself great, need reserve more dismantlement space, and secondly the biggest stroke of C shape pincers is fixed, can not adjust, has certain limitation. Therefore, there is still a need to design a new spring retractor to solve the above-mentioned deficiencies.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model lies in, to prior art's above-mentioned defect, provide a compact and small spring tightener.
The utility model provides a technical scheme that its technical problem adopted is:
constructing a compact and small spring tightener, wherein the spring tightener comprises a movable threaded rod which penetrates through a template bearing plate and is in threaded connection with the template bearing plate during tightening, a threaded sleeve which is matched with the movable threaded rod, and a leveling block which is used for matching and clamping an ejector plate and the threaded sleeve during tightening; the leveling block comprises a main block body attached to the threaded sleeve and a plurality of groups of leveling bolts which are positioned on one side of the main block body, which is far away from the threaded sleeve, and are uniformly distributed in the circumferential direction; the leveling bolt is in threaded connection with the main block body; and a fastening bolt with the tail end abutting against the movable threaded rod and a threaded hole matched with the fastening bolt are arranged on the side surface of the threaded sleeve.
Preferably, the lateral surface of the threaded sleeve is further provided with a transverse handle and a positioning hole matched with the transverse handle.
Preferably, the positioning hole is a blind hole.
Preferably, a rubber pad is fixedly arranged on one side of the leveling bolt, which is far away from the threaded sleeve.
The beneficial effects of the utility model reside in that: compact structure and convenient for change the stroke. Specifically, when the adjustable screw type leveling mechanism is used, the extending length of each leveling bolt is adjusted, so that the leveling block and the ejector plate are kept in a parallel state, and a movable threaded rod is smoothly screwed on the template bearing plate; and then the threaded sleeve is rotated to drive the movable threaded rod to synchronously rotate, and the ejector plate is pushed to approach the template bearing plate, so that the aim of tightening the spring is fulfilled. When the template bearing plate of different thickness need be operated, unscrew fastening bolt, can change the movable threaded rod of different length, it is convenient to change.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be further described below with reference to the accompanying drawings and embodiments, wherein the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work according to the drawings:
FIG. 1 is a cut-away view of a compact and compact spring retractor according to a preferred embodiment of the present invention;
fig. 2 is a schematic diagram of a compact and compact spring retractor according to the preferred embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, a clear and complete description will be given below with reference to the technical solutions of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
A compact and small spring tightener of the preferred embodiment of the present invention is shown in fig. 1-2, and comprises a movable threaded rod 10 passing through and in threaded connection with the template bearing plate 2 during tightening, a threaded sleeve 11 adapted to the movable threaded rod 10, and a leveling block 12 for the ejector plate 3 and the threaded sleeve 11 to be clamped in cooperation during tightening; the leveling block 12 comprises a main block body 13 attached to the threaded sleeve 11 and a plurality of groups of leveling bolts 14 which are positioned on one side of the main block body 13, which is far away from the threaded sleeve 11 and are uniformly distributed on the circumference; the leveling bolt 14 is in threaded connection with the main block body 13; the side surface of the threaded sleeve 11 is provided with a fastening bolt 15 the tail end of which abuts against the movable threaded rod 10, and a threaded hole 180 adapted to the fastening bolt 15. This spring tightener possesses compact structure and is convenient for change the advantage of stroke, and is specific: when in use, the extension length of each leveling bolt 14 is adjusted, so that the leveling block 12 and the ejector plate 3 are kept in a parallel state, and the movable threaded rod 10 is smoothly screwed on the template bearing plate 2; and then the threaded sleeve 11 is rotated to drive the movable threaded rod 10 to synchronously rotate, and the ejector plate 3 is pushed to approach the template bearing plate 2, thereby realizing the purpose of tightening the spring. When the template bearing plates 2 with different thicknesses are required to be operated, the fastening bolts 15 are unscrewed, and the movable threaded rods 10 with different lengths can be replaced conveniently.
It should be noted that the template bearing plate 2 is provided with a threaded through hole matched with the movable threaded rod 10 in advance, and the ejector plate 3 is provided with an avoiding through hole avoiding the movable threaded rod 10 in advance.
As shown in fig. 1-2, the lateral surface of the threaded sleeve 11 is further provided with a transverse handle 16 and a positioning hole 181 matched with the transverse handle 16, so that when the spring is tightened, the transverse handle 16 can be held to drive the threaded sleeve 11 to rotate, and the use is more convenient.
As shown in fig. 1-2, the positioning hole 181 is a blind hole to avoid repeatedly scraping the movable threaded rod 10.
As shown in fig. 1-2, a rubber pad 17 is fixedly arranged on one side of the leveling bolt 14 away from the thread bush 11, so that the anti-skid effect is good and the ejector plate 3 is not scratched.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are considered to be within the scope of the invention as defined by the following claims.
