Description
Technical field
The utility model relates to specialized hand tool field, and especially a kind of reversible ratcheting tool is used for the plate heat exchanger the fixing hex nut of heat transferring plate is carried out installation and removal.
Background technology
The applicant formerly discloses a kind of sheet structure among the patent ZL200820150509.4 at it, with most sheet heat transferring plates formation heat exchanger components that stacks together, constitutes the plate heat exchanger then, often is applied in the board-like sterilizing installation.
Most sheet heat transferring plates are fastening through hex nut in stacked back; In order to guarantee the operate as normal of plate heat exchanger, nut must tighten up, but makes when heat transferring plate need be repaired or clean; The plate volume that adds heat exchanger is bigger, and it is very difficult that the dismounting hex nut seems again.Commonly used is common die nut now, and handle is long and heavy, and does not have forward to unclamp, and the two-way function of reverse locking makes the operative employee feel very inconvenience to have reduced operating efficiency.
Summary of the invention
The utility model technical problem to be solved is to provide a kind of and the supporting reversible ratcheting tool of plate type heat exchanger, when heat transferring plate need be repaired, can be conveniently the fixing hex nut of heat transferring plate be carried out installation and removal.
The utility model solves the problems of the technologies described above the technical scheme of being taked: a kind of reversible ratcheting tool; Be used for the stacked hex nut that compresses of the most sheet heat transferring plates of plate heat exchanger and compress adjusting, installation and removal; Comprise shell, handle and sleeve core, wherein:
Described shell is made up of sleeve and connecting portion, and described barrel bore is circular, and sleeve links to each other with handle through connecting portion; Place, two sides at connecting portion is equipped with opening; Slide block is set in the connecting portion, and the slide block middle part is provided with axis hole, and latch passes this axis hole sliding shoe is connected with the connecting portion bearing pin; The both sides of slip front are respectively equipped with first ratchet and second ratchet; The both sides of slide block are respectively equipped with the pushed section, have the pushed section of a side to be exposed to outside the opening of connecting portion side all the time, and the rear portion of slide block is provided with protuberance;
Described sleeve core is located in the sleeve; Cylindrical is provided with a circle ratchet, and inner circle is provided with the draw-in groove of a circle and the peripheral screens of hex nut, and the both ends of the surface of sleeve core all protrude from sleeve and form projecting surface; By jump ring screens from the outside, and the sleeve core can be done 360 ° of rotations in sleeve at this projecting surface place;
Described handle front end is provided with inside groove, and spring is set in the inside groove, and the spring front end is placed steel ball, and steel ball is spacing and replace with the protuberance of slide block by this inside groove;
This first ratchet or second ratchet mesh with the ratchet maintenance of sleeve core all the time, and the engagement of the engagement direction of first ratchet and sleeve core ratchet and second ratchet and sleeve core ratchet is in the opposite direction.
On the basis of such scheme, the protuberance at said slide block rear portion is a triangle, and steel ball is replaced under acting force of the spring all the time on an inclined-plane of this triangle protuberance, conveniently stirs pushing block simultaneously.
On the basis of such scheme, the outer rim place, protruding end of said sleeve core is provided with the jump ring groove, and jump ring is the abutment sleeve core in this jump ring groove.
The operation principle of the utility model is:
Slide block and connecting portion pivotal connection; Just slide block can be swung around axle; And the triangle protuberance of slide block makes first ratchet (or second ratchet) of the anterior side of slide block keep engagement with the sleeve core ratchet that is located in the outer casing sleeve all the time under the replacing of the steel ball of spring front end; Under the restriction of ratchet direction, the sleeve core only can rotate in sleeve toward the direction.The sleeve core of spanner is buckled in the hex nut outside, and the draw-in groove of sleeve in-core circle blocks hex nut, can make things convenient for installation, the dismounting of hex nut to its adjusting of unclamping or tightening.
Slide block plays the effect that changes sleeve core direction of rotation from the pushed section that connecting portion exposes.The pushed section that to expose inwardly pushes; First ratchet (or second ratchet) of this moment of engagement originally breaks away from sleeve core ratchet; And another pushed section that the slide block opposite side is received in the connecting portion originally is pushed out, second ratchet (or first ratchet) that breaks away from originally simultaneously and sleeve core ratchet engagement.Again because the engagement direction of first ratchet and sleeve core ratchet is in the opposite direction with the engagement of second ratchet and sleeve core ratchet, the sleeve core only can be towards rotating with before opposite direction at this moment, thereby the hex nut on the counterweight new clothes is tightened (or unclamping).
The beneficial effect of the utility model is:
The reversible ratcheting tool of the utility model is the kit that plate type heat exchanger provides a kind of special use; Being used for fixedly the hex nut of heat exchange plate tightens or unclamps; It is little to have volume, characteristics in light weight, and through promoting the engagement direction that slide block can change ratchet; Thereby make the sleeve core to different direction rotations, further facilitated operation.
