Detailed Description
The following describes in further detail the embodiments of the present application with reference to the drawings and examples. The following examples are illustrative of the application and are not intended to limit the scope of the application.
Referring to fig. 1 and 2, a workbench 100 according to a preferred embodiment of the application can be applied to cutting, assembling, etc. of a target object, and the application is not limited to other application scenarios. Specifically, the table 100 includes: a table top board 1, a supporting mechanism 2 for supporting the table top board, a handle 3 movable relative to the table top board 1, and a link mechanism 4; wherein the support mechanism 2 comprises a first leg assembly 21 and a second leg assembly 22, and the linkage 4 is connected to the handle 3, the first leg assembly 21 and the second leg assembly 22. When the handle 3 is operated, the first leg assembly 21 and the second leg assembly 22 are extended from the deck plate 1 or retracted into the deck plate 1 via the movement of the link mechanism 4. In this embodiment, the table top 1 has a rectangular shape and has a first side 11 and a second side 12 opposite to each other, and the length of the first side 11 is not less than the length of the second side 12, i.e. the length of the first side 11 is greater than or equal to the length of the second side 12. The handle 3 is slidable relative to the deck plate 1. Specifically, the handle 3 is slidable in a first direction (a) and a second direction (b) of the deck plate 1, the first direction (a) and the second direction (b) being opposite directions.
As described above, in the present embodiment, the first direction (a) and the second direction (b) are disposed along the second side 12 of the deck plate 1, that is, parallel to the second side 12. The handle 3 is forced to slide along the first direction (a) of the table top board 1, and then the link mechanism 4 drives the first leg component 21 and the second leg component 22 to slide along the first side edge 11 of the table top board 1 and rotate until the first leg component 21 and the second leg component 22 retract into the table top board 1, and the table 100 is folded; similarly, the handle 3 is forced to slide along the second direction (b) of the table top 1, so that the link mechanism 4 drives the first leg assembly 21 and the second leg assembly 22 to slide and rotate along the first side 11 of the table top 1 until the first leg assembly 21 and the second leg assembly 22 extend out of the table top 1, and the table 100 is unfolded.
It should be noted that, in the present embodiment, the sliding and rotating of the first leg assembly 21 and the second leg assembly 22 are performed simultaneously, and the sliding is used to assist the first leg assembly 21 and the second leg assembly 22 to extend out of the table top 1 or retract into the table top 1 more conveniently, and make the entire table top 1 more compact and small for easy carrying. That is, when the first leg assembly 21 and the second leg assembly 22 are simultaneously moved in a direction away from or toward the handle 3, the first leg assembly 21 and the second leg assembly 22 are also rotationally moved while being displaced in the horizontal direction.
In this embodiment, the handle 3 is provided on the first side 11 of the deck plate 1. The purpose of this arrangement is that: when the workbench 100 is completely folded and the user holds the handle 3 to move, the distance between the hand of the user and the ground is determined by the second side 12 of the workbench 100, at this time, the distance between the bottom end of the workbench 100 and the ground is larger, so that collision with other objects on the ground when carrying the workbench 100 is avoided, and the user can carry the workbench 100 more conveniently; when the handle 3 is disposed on the second side 12, the distance between the hand of the user and the ground is determined by the first side 11 of the table 100, and at this time, the distance between the bottom end of the table 100 and the ground is smaller, the table 100 is easy to interfere with the ground, and it is difficult for the user to carry the table 100.
And, the movement direction of the handle 3, i.e. the first direction (a) and the second direction (b), is parallel to the axis of rotation of the leg assembly. When the operating handle 3 opens or folds the workbench 100, the user is always positioned at the periphery of the support mechanism 2 which performs the overturning motion, and the support mechanism does not touch the user, so that the safety of the user can be effectively protected.
Meanwhile, when the workbench 100 is folded by the operating handle 3, the first side edge of the operating handle 3 is not fully contacted with the ground, and one of the first leg assembly 21 and the second leg assembly 22, which is close to the ground, is contacted with the ground to play an auxiliary supporting role, so that the workbench 100 is more stable when being folded.
In order to guide the sliding direction of the handle 3 and to limit the sliding range of the handle 3, the table 100 further includes a first sliding groove 5 provided at the bottom of the table top 1, and one end of the handle 3 is provided in the first sliding groove 5 and is slidable in the first sliding groove 5. As described above, the first chute 5 is disposed along the second side 12 of the deck plate 1.
Referring to fig. 3 to 5, the link mechanism 4 includes a first support rod 41 for connecting the first leg assembly 21, a second support rod 42 for connecting the second leg assembly 22, a first link 43 for movably connecting the handle 3 and the first support rod 41, and a second link 44 for movably connecting the handle 3 and the second support rod 42; the linkage 4 further includes a third link 40 that pivotally connects the deck plate 1 to the first leg assembly 21 and a fourth link 49 that pivotally connects the deck plate 1 to the second leg assembly 22. The third link 40 is pivotally connected to the deck plate 1 and the first leg assembly 21, and the fourth link 49 is pivotally connected to the deck plate 1 and the second leg assembly 22. As described above, the connection points of the third link 40, the fourth link 49 and the deck plate 1 are located in the second side direction of the deck plate 1.
Specifically, referring to fig. 12 to 14, when the workbench 100 is folded, an external force is applied to drive the handle 3 to slide along a direction parallel to the second side 11, and the first link 43 and the second link 44 respectively drive the first support bar 41 and the second support bar 42 to slide at least parallel to the first side 11, so that the first leg assembly 21 and the second leg assembly 22 move and turn over along with the first support bar 41 and the second support bar 42 towards the center line or away from the center line under the action of the third link 40 and the fourth link 49, and thus extend or retract relative to the table panel 1, which is convenient and fast.
The deck plate 1 has a centre line parallel to the direction of the second side 12 of the handle 3, and in this embodiment the linkage 4 is arranged symmetrically about the centre line. That is, the first link 43 and the second link 44 are symmetrically arranged about the center line, and the first support bar 41 and the second support bar 42 are symmetrically arranged about the center line. That is, in the present embodiment, the first link 43 and the second link 44 are identical in structure, the first support bar 41 and the second support bar 42 are identical in structure, and the third link 40 and the fourth link 49 are identical in structure.

Under this scheme, when the operating handle 3 moves, the first connecting rod 43 drives the first supporting rod 41 to slide along the direction of the first side 11. The middle portion of the first supporting rod 41 is provided with a limiting mechanism (not numbered) for limiting the moving range of the first supporting seat 46, and in this embodiment, the moving range of the first supporting seat 46 is limited by a limiting pin (not numbered), and in other embodiments, the limiting mechanism may be provided with other limiting mechanisms such as a limiting block. Indeed, in other embodiments, the rotation connection manner between the first end and the handle 3 may be other, and the rotation connection manner between the other end and the first support rod 41 may be other, for example, a connection seat (not shown) may be provided on the handle 3, and the first end is rotationally connected to the connection seat of the handle 3, where the connection seat and the handle 3 may be integrally formed, or may be fastened, welded, or other fixing manners.

One end of the second connecting rod 44 is rotatably connected with the handle 3, and the other end of the second connecting rod 44 is rotatably connected with the second supporting rod 42. In this embodiment, one end of the second link 44 is rotatably connected to the handle 3 through a rotation shaft, and the other end is rotatably connected to the second support rod 42 through a second support seat 48 sleeved on the second support rod 42. At this time, the second supporting seat 48 and the second supporting rod 42 are connected in two ways: one is a clearance fit, which allows the two to rotate relative to each other, with the second support bar 42 and the second leg assembly 22 being interference or locked together; under the scheme, when the operating handle 3 moves, the second connecting rod 44 drives the second supporting rod 42 to perform compound movement, including sliding along the direction of the first side 11 and rotation around the axis of the second supporting rod 42; the other is that the second support seat 48 and the second support rod 42 are in interference fit, and the two synchronous motions cannot rotate mutually, and at the moment, the second support rod 42 and the second leg assembly 22 are in clearance fit. Under this scheme, when the operating handle 3 moves, the second connecting rod 44 drives the second supporting rod 42 to slide along the direction of the first side 11. The middle portion of the second support rod 42 is provided with a limiting mechanism (not numbered) for limiting the movement range of the second support seat 48, in this embodiment, the movement range of the second support seat 48 is limited by a limiting pin (not numbered), and in other embodiments, the limiting mechanism may be provided with other limiting mechanisms such as a limiting block. Indeed, in other embodiments, the rotational connection manner between one end and the handle 3 may be other, and the rotational connection manner between the other end and the second support rod 42 may be other, for example, a connection seat (not shown) may be provided on the handle 3, and the second connection end is rotationally connected to the connection seat of the handle 3, where the connection seat and the handle 3 may be integrally formed, or may be fastened, welded, or other fixing manners.
