Abstract
The utility model relates to a mechanical automatic locking mechanism, which is formed by engaging a gear [1] and a cylindrical gear [2]. The utility model is characterized in that a ratchet-shaped friction surface [4] is arranged on the cylindrical gear [2], a fixed ratchet wheel [5] and the ratchet-shaped friction surface [4] are correspondingly provided with ratchet-shaped friction surfaces [7], and cylindrical gear [2], the ratchet-shaped friction surface [4], and the ratchet-shaped friction surface [7]on the fixed ratchet wheel [5] are correspondingly sheathed on a shaft [8] which is provided with a spring [6]. The utility model has the advantages of simple structure, convenient operation, low cost, easy popularization, etc.
Description
The utility model relates to a kind of mechanical self-latching mechanism, especially relates to one group of gear-driven self-locking mechanism.
The mechanical self-latching mechanism that generally uses all is to combine with gear and ratchet at present, and ratchet is provided with locating stud, described locating stud and ratchet match, when the gear forward direction was rotated, the ratchet that gear driven is meshed with gear rotated, and this moment, ratchet was stirred the locating stud location.The mechanical self-latching mechanism of this structure positions by locating stud fully, if make the gear reverse rotation, must at first open locating stud, has deficiencys such as complex structure, numerous, the cost height of operation.
The purpose of this utility model is at the deficiencies in the prior art part, provides a kind of easy and simple to handle, arbitrarily transmitting gear sense of rotation and carry out the mechanical self-latching mechanism of lock-bit voluntarily.
The purpose of this utility model realizes in the following way, gear is meshed with cylindrical gears, it is characterized in that one of them side plane of described cylindrical gears is provided with the attrition surface of band ratchet-like, be provided with corresponding with the band ratchet-like attrition surface on the described cylindrical gears decided the ratchet-like attrition surface and matched, described cylindrical gears is set on the wheel shaft, also is provided with spring on the axle.
The utility model adopts the elastic force of spring to make to decide the band ratchet-like attrition surface on ratchet-like attrition surface and the cylindrical gears disk decided on the ratchet to match and produce friction and realize locating, when the reverse rotation gear, need only overcome because of spring action causes the band sour jujube shape attrition surface and the friction of deciding to be produced between the sour jujube shape attrition surface to get final product in the power of deciding ratchet, needn't be provided with and stir the ratchet catch means, have simple in structure, easy to use, cost is low, is easy to remarkable advantages such as popularization.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of the utility model cylindrical gears.
Now in conjunction with the accompanying drawings, a detailed description specific embodiment of the present utility model:
As shown in Figure 1, having the tooth sector 1 of long handle is meshed with tooth 3 on cylindrical gears 2 circumferential surfaces, as shown in Figure 2, a disk of described cylindrical gears 2 is provided with the attrition surface 4 of band ratchet-like, on the axle 8 spring 6 is installed, decide on the ratchet 5 with described cylindrical gears 2 on the band ratchet-like attrition surface 4 corresponding attrition surfaces 7 of deciding ratchet-like that are provided with are arranged, described cylindrical gears 2 band ratchet-like attrition surfaces 4 with decide ratchet 5 on decide that ratchet-like attrition surface 7 is relative to be sleeved on spools 8 by ground, decide ratchet 5 and be fixed on the support by axle 8.
When concrete the use, rotate the tooth sector 1 that has long handle, drive cylindrical gears 2 and overcome under the effect of spring 6, result from band ratchet-like attrition surface 4 and decide the friction between the ratchet-like attrition surface 7 and rotate.When the tooth sector 1 that has long handle turns to after certain position stops operating, under the effect of friction, locate voluntarily.
Claims (2)
1, a kind of mechanical self-latching mechanism, be meshed with tooth [3] on cylindrical gears [2] circumferential surface by gear [1] and form, a side that it is characterized in that described cylindrical gears [2] is provided with band ratchet-like attrition surface [4], with band ratchet-like attrition surface [4] be provided with accordingly decide ratchet-like attrition surface [7] decide ratchet [5], the cylindrical gears that is reached [2] go up ratchet-like attrition surface [4] with decide on the ratchet [5] decide ratchet-like attrition surface [7] and to being sleeved on by ground on the axle [8], spool [8] are provided with spring [6].
2, a kind of mechanical self-latching as claimed in claim 1 mechanism is characterized in that described gear [1] is the tooth sector that has long handle.
