Technical field

The utility model is relevant with the bracing frame that is used for facility, particularly relevant for a kind of simple in structure and easy to operate bracing frame.

Background technology

U.S.'s Announcement Number the 6th, 311, No. 992 patents and the 6th, 533, No. 524 patent discloses a kind of bracing frame respectively, and this two bracing frame has one first framework and one second framework respectively, when driving this second framework when forcing in this first framework, this bracing frame is supportted overhead, and the action that can utilize the roller that is hubbed at this first framework and this second framework to carry.

All quite complicated with regard to the structure of above-mentioned two patents, and the relation of the drive between this two framework is uncertain, inconvenient in the operation.

In addition, TaiWan, China Announcement Number I289101 patent then discloses out another kind of bracing frame, mainly is to utilize to trample a drivening piece and the start by plural moving part, allows each roller ground of down conflicting, and allow each feet built on stilts, so that carry out transport operation.The defective that has aforementioned patent but the structural relation of this patent is also quite complicated equally.

The utility model content

The purpose of this utility model is to provide a kind of movably bracing frame, and it is simple in structure, and is easy to operate, can increase the convenience in the use.

For achieving the above object, the bracing frame that the utility model provides includes a pedestal, a roller mount, and an actuator.This pedestal has plural feet; This roller mount has a pedestal and plural roller, and this pedestal is hubbed at the feet of this pedestal, and those rollers are hubbed at this pedestal; This actuator has one first drive rod and one second drive rod, and the top of this first drive rod articulates this pedestal, and the bottom of this second drive rod articulates the pedestal of this roller mount, and the top of the bottom of this first drive rod and this second drive rod articulates mutually.

When this actuator is positioned at a use location, having a pedestal that can drive this roller mount less than the angles of 180 degree between this first drive rod and this second drive rod pivots, make the feet kiss the earth of those roller built on stilts and this pedestal, and carry the position when this actuator is positioned at one, having a pedestal that can not drive this roller mount more than or equal to the angles of 180 degree between this first drive rod and this second drive rod pivots, make those roller kiss the earths, and prop up this pedestal and allow the feet built on stilts of this pedestal.

By above-mentioned design as can be known, as long as this actuator is driven from this use location to this carrying position by the pivot between this first drive rod and this second drive rod, can allow those roller kiss the earths, allow those feet built on stilts simultaneously, so that bracing frame of the present utility model is carried to needed position; On the contrary, when driving to this use location from this carrying position this actuator by the pivot between this first drive rod and this second drive rod, those rollers are with built on stilts, those feets are kiss the earth then, so just can use a cutting machine tool that is fixed on this pedestal top to process operation.

The specific embodiment

In order to describe structure of the present utility model, feature and effect place in detail, lift following preferred embodiment and conjunction with figs. and be described as follows.

See also Fig. 1, be the bracing frame 10 that the utility model one preferred embodiment is provided, include a pedestal 20, a roller mount 30, and an actuator 40 (consulting Fig. 3).

Pedestal 20 has a bearing frame 22 and two pairs of feets 24,26.Those

feets

24,26 are extended downwards by four corners of bearing frame 22 respectively and with its bottom kiss the earth, make the bearing frame 22 can be in order to fixing and support a cutting machine tool 50, as shown in Figure 2.

Roller mount 30 has a pedestal 32 and four rollers 34.Pedestal 32 has a first connecting rod 322 second connecting rod 324 relative with two, and each second connecting rod 324 articulates a wherein feet 26 of pedestal 20 with the one end, and connects a wherein end of first connecting rod 322 with its other end; Second wheel 34 first connecting rod 322 of pedestal 32 that is pivoted wherein, second wheel 34 is hubbed at a wherein second connecting rod 324 of pedestal 32 respectively in addition.

Please cooperate and consult Fig. 3 and Fig. 5, actuator 40 has one first drive rod 42 and one second drive rod 44.The top of first drive rod 42 articulates the bearing frame 22 of pedestal 20, the bottom of second drive rod 44 articulates the first connecting rod 322 of the pedestal 32 of roller mount 30, and the top of the bottom of first drive rod 42 and second drive rod 44 articulates mutually, first drive rod 42 and second drive rod 44 can be pivoted relative to each other and allow actuator 40 in a use location P1 and one the carrying position P2 between conversion.When actuator 40 is positioned at use location P1, as shown in Figure 3, has an angle [alpha] less than 180 degree between first drive rod 42 and second drive rod 44, and carry position P2 when actuator 40 is positioned at, as shown in Figure 5, have an angle beta greater than 180 degree between first drive rod 42 and second drive rod 44, angle beta is not limited to greater than 180 degree, as long as all can more than or equal to 180.In addition, actuator 40 also has one first pedal 46 and one second pedal 48, wherein, first pedal 46 is located at the bottom of second drive rod 44, as Fig. 3 and shown in Figure 5, can be subjected to the external force effect and drive first drive rod 42 and second drive rod 44 and pivot, in order to actuator 40 is driven to carrying position P2 as shown in Figure 5 by use location P1 shown in Figure 3 towards direction near the side of bearing frame 22; Second pedal 48 is located at the mutual articulated section of second drive rod 44 and contiguous first drive rod 42 and second drive rod 44, can be subjected to the external force effect and drive first drive rod 42 and second drive rod 44 and pivot, in order to actuator 40 is driven to use location P1 as shown in Figure 3 by carrying position P2 shown in Figure 5 towards direction away from the side of bearing frame 22.

When operating personnel's desire carrying bracing frame 10, earlier trample first pedal 46 with single pin, actuator 40 is driven to carrying position P2 by use location P1, make angle between first drive rod 42 and second drive rod 44 be changed to the angle beta of Fig. 5 by the angle [alpha] of Fig. 3, at this moment, the pedestal 32 of roller mount 30 will deflect down along with being pivoted relative to each other between first drive rod 42 and second drive rod 44, make those roller 34 kiss the earths, and pedestal 20 upwards propped up, allow the feet 24 of

pedestal

20,26 built on stilts, as Fig. 4 and shown in Figure 5, thus, operating personnel can utilize those rollers 34 that bracing frame 10 of the present utility model is transported to needed position.

After operating personnel are transported to this position with bracing frame 10 of the present utility model, as long as operating personnel trample second pedal 48, carrying position P2 by Fig. 5 drives to the use location P1 as Fig. 3 with actuator 40, in this case, the pedestal 32 of roller mount 30 will be subjected to the drive of second drive rod 44 and upward deflect, make those roller 34 built on stilts, the

feet

24,26 of pedestal 20 will descend and contact residence face, as shown in Figure 1 to Figure 3, the action that can process by the cutting implement 50 that is fixed on bracing frame 10 tops of operating personnel.

Comprehensive the above, bracing frame of the present utility model is by the pivot between first drive rod and second drive rod, can control the feet contact and the built on stilts of those rollers or pedestal according to the needs of actual state, so that carry or process operation, make bracing frame of the present utility model have simple in structure and easy to operate characteristic really and reach the purpose that increases ease of use.

The constituent components of the utility model described in the embodiment only for illustrating, is not to be used for limiting scope of the present utility model, the substituting or change of other equivalent elements, and the claim scope that also should be application contains.
