Abstract

The utility model discloses a safety support, which comprises a foot stand and an ejecting rod flexibly inserted on the foot stand. A ratchet is arranged on the side of the ejecting rod, a limit mechanism flexibly arranged on the top portion of the foot stand is in mutual position clipping with the ratchet so as to limit lifting of the ejecting rod in a clipping way, the limit mechanism comprises a handle at the front end, a pin rod, a pair of slotted holes and a self-locking structure, the handle is in rotating connection with the foot stand, the pin rod of the position clipping ratchet is disposed in the middle portion of the handle, the pair of slotted holes arranged at positions, corresponding to the ratchet, on the top portion of the foot stand limit rotation range of the handle, and the self-locking mechanism arranged on the limit mechanism comprises a bolt penetrating the two slotted holes . The ejecting rod is incapable of moving up and down after the bolt is inserted into the slotted holes, thereby bringing convenience for carrying. The rotating type limit mechanism brings convenience to height adjustment operation of the ejecting rod, and the added self-locking structure prevents the ejecting rod from moving up and down so as to be convenient for carrying and also improve safety performance.

Description

A kind of security bracket

Technical field

The utility model relates to a kind of support, especially a kind of security bracket that is used with jack.

Background technology

When making heavy-duty machineries such as the vehicle body of jack-uping, lathe, for the sake of security, need place the effect that security bracket plays supplemental support in the bottom usually.Because the height of jack stand weight is to regulate arbitrarily according to actual needs, so the height of security bracket also is to want adjustable.

Its structure of existing security bracket mostly is a bolt-type, includes push rod, foot rest and latch etc., in use, adjusts the height of push rod earlier, pin alignment pins hole is inserted again, each plug latch that highly all needs repeatedly of regulating, operation inconvenience; In addition, existing security bracket is because the design-calculated original intention, the fastener screens when being under pressure, push rod is arranged, but in when promoting fastener is set, push rod is easy to just be pulled out, though be convenient to like this regulate, it is very inconvenient that the carrying of security bracket just becomes, have only and hard hold foot rest and just can move security bracket.

Summary of the invention

Problem to be solved in the utility model is exactly at shortcoming of the prior art, and a kind of simple in structure, security bracket of being convenient to carry is provided, and is easy to operate, safe in utilization.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of security bracket, comprise foot rest and the active push rod that is inserted on the foot rest, it is characterized in that: the push rod side is provided with ratchet, and the stop gear of active setting in foot rest top and the mutual screens of ratchet is used for the lifting of blocking push rod.

Further, described stop gear comprises the handle of front end switching on foot rest, and the handle middle part is provided with the pin rod that is positioned in ratchet, and corresponding ratchet position, foot rest top is provided with a pair of waist shaped hole restriction handle slewing area.

Further, also be provided with self-locking structure on the stop gear, this self-locking structure is to be installed on two latches between waist shaped hole.After latch inserted waist shaped hole, push rod just can't move up and down, and was convenient to carrying.

Preferably, described latch one end is connected with handle by chain, is convenient to from latching operation.

Further, described ratchet indentation and tooth mouth down are provided with, and push rod can upwards draw high under the situation of no bolt self-locking adjusts height.

Further, described push rod upper end is provided with the support saddle, is used to withstand weight.

Further, support saddle and push rod are the cast iron integrated formed structure.

Advantage of the present utility model: make the height adjustment operation of push rod become convenient by a revolving stop gear; The self-locking structure that increases can't move up and down push rod, is convenient to carrying, has also improved safety performance.In addition, the utility model also has the characteristics that working surfaces is many, working stability is reliable, bearing capacity is big, practical life is long.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is running condition figure one of the present utility model;

Fig. 2 is running condition figure two of the present utility model.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model is a kind of security bracket, comprises foot rest 1 and the active push rod 2 that is inserted on the foot rest 1, and push rod 2 upper ends are provided with support saddle 21, are used to withstand weight; Support saddle 21 is the cast iron integrated formed structure with push rod 2.Push rod 2 sides are provided with ratchet 22, and ratchet 22 indentations and tooth mouth down are provided with, and push rod 2 can upwards draw high under the situation of no bolt self-locking adjusts height; The lifting of the stop gear blocking push rod 2 of active setting in foot rest 1 top and ratchet 22 mutual screens.This stop gear comprises the handle 3 of front end switching on foot rest 1, and handle 3 middle parts are provided with the pin rod 31 of screens ratchet 22, and corresponding ratchet 22 positions, foot rest 1 top are provided with a pair of waist shaped hole 11 restriction handles 3 slewing areas.Also be provided with self-locking structure on the stop gear, this self-locking structure is the latch 4 that is installed on 11 of two waist shaped holes, and latch 4 one ends are connected with handle 3 by chain 41, and latch 4 is after inserting waist shaped hole 11, and push rod 2 just can't move up and down, and is convenient to carrying.

During use, upwards turning handle 3 makes its pin rod 31 break away from ratchet 22, adjusts push rod 2 height; Release handle 3, this moment, handle 3 automatic whereabouts and pin rod 31 screens limited the decline of push rod 2 in ratchet 22, can select that at this moment latch 4 is inserted waist shaped holes 11 and be used for locking, and push rod 2 can't upwards be extracted, and were convenient to carrying.
