Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, fig. 2 and fig. 7, the workbench 100 of the present embodiment includes a workbench unit 110 and a bracket 120 detachably connected to the workbench unit 110, wherein the workbench unit 110 includes a first workbench unit 112 and a second workbench unit 114 having the same shape and size. During production, only one mold is needed, and the mold cost is reduced.

Referring to fig. 3 and 7, the workbench further includes a rotating shaft 111 connecting the first workbench unit 112 and the second workbench unit 114, the first workbench unit 112 and the second workbench unit 114 can rotate relative to the rotating shaft 111 to form a bracket placing cavity 140, and the folded portion of the bracket 120 is accommodated in the bracket placing cavity 140, and two ends of the bracket are exposed. That is, the work bench 100 has two states, i.e., a working state and a folded state (i.e., transportation and storage states), wherein the working state includes a first working state in which the rack is connected and a second working state in which the rack is not connected (as described in detail below). Correspondingly, the table unit 110 also has two states of unfolding and folding, and the unfolded state corresponds to the two operating states. In the unfolded state, the first table unit 112 and the second table unit 114 are centrosymmetric with respect to the geometric center of the table unit 110.

Referring to fig. 1 to 3, the stand 120 includes support legs 122 and a connection rod 123, and the stand 120 can be folded and unfolded. The support legs 122 have support leg mounting seats at the top and bottom ends thereof, respectively, and a support leg mounting block 124 is provided on the upper surface of the support leg mounting seat at the top end of the support leg 122 for connection with the table unit 110. Two supporting legs corresponding to each side of the workbench unit 110 are also provided with mutually crossed connecting rods 123, the two connecting rods 123 are mutually hinged together at the crossed position, and the end parts are connected to the supporting leg mounting seats. The connecting rod 123 is used to connect the supporting legs 122 to form a whole, i.e., a bracket. The support leg is divided into two parts, a bottom support leg 1221 and an upper support leg 1222, the bottom support leg 1221 has a blind hole therein, and the upper support leg 1222 is inserted into the blind hole of the bottom support leg 1221 and can be moved along the blind hole, so that the stand constituted by the support leg 122 and the connecting rod 123 can be folded and unfolded.

Taking the first table unit 112 as an example, please refer to fig. 4 to 6, the first table unit 112 includes a rectangular first portion 112a and a second portion 112b adjacent to the first portion, and the second portion 112b includes a plurality of spaced protrusions 1122 and recesses 1123 corresponding to the protrusions. The second portion may be considered to be rectangular in shape, with the rectangle of the second portion 112b aligned lengthwise with the rectangle of the first portion 112 a. The upper surface of the first portion 112a is coplanar and contiguous with the upper surface of the second portion 112b to form a first working surface 1120 that supports a workpiece. The first portion 112a is provided with a recess 116 downward from the first working surface 1120, and a substantially rectangular through hole 1161 penetrating downward is provided in the recess 116, and the through hole 1161 is used for fixing the bracket 120. The through hole 1161 has substantially the same size as the support leg mounting block 124, thereby allowing the support leg mounting block 124 to pass therethrough. After the support leg mounting block 124 passes through the through hole 1161, the support leg mounting block 124 can be rotated by a hand at an angle so that the support leg mounting block 124 is positionally displaced from the through hole 1161, so that the support leg mounting block 124 contacts with the bottom wall of the recess 116 to abut against each other, thereby mounting the support leg 120 to the first table unit 112. In other embodiments, the through hole 1161 may have other shapes as long as the supporting and mounting block 124 is allowed to pass through, and after the rotation, the recess 116 can prevent the supporting and mounting block 124 from being detached, so as to ensure the stable connection between the table unit 110 and the bracket 120.

Notably, the recess 116 can completely receive the support leg mounting block 124, preventing it from protruding beyond the working surface 1100 (or first working surface 1120) and affecting the supported workpiece.

The first table unit 112 has a first side 1126 parallel to the longitudinal direction a, a second side 1127 and a third side 1128 perpendicular to the longitudinal direction a, i.e., the second side 1127 and the third side 1128 are disposed on both longitudinal sides of the first table unit 112. The first table unit 112 is provided with a first leg 1124 and a second leg 1125 at a top corner of the first portion 112a far from the second portion 112b, the first leg 1124 extends from the first side 1126 and the second side 1127 of the first table unit 112 in a direction away from the first working surface 1120, the second leg 1125 extends from the first side 1126 and the third side 1128 of the first table unit 112 in a direction away from the first working surface 1120, that is, the extending directions of the first leg 1124 and the second leg 1125 are the same and are formed by extending from both sides. Of course, the first leg 1124 (or the second leg) may extend from only one side. When the table unit 110 is in the unfolded state and not connected to the support 120, the first leg 1124 and the second leg 1125 protrude from the bottom surface of the first portion 112a and the second portion 112b facing away from the first working surface 1120. The first leg 1124 and the second leg 1125 of the first table unit 112 and the first leg 1144 and the second leg 1145 of the second table unit 114 are used together as a support for the table 100, and the table (without a support) is a shorter table, i.e. the second working state mentioned above.

In addition, in the extending direction of the first leg portion 1124 and the second leg portion 1125, the transverse dimension (the dimension perpendicular to the extending direction) of both gradually decreases along the extending direction, and the reason for this is explained below.

The convex portions 1122 and the concave portions 1123 are staggered; and the convex portions 1122 and the concave portions 1123 are maintained in alignment in a direction b perpendicular to the longitudinal direction a of the second portion 112 b. Specifically, in the longitudinal direction of the second portion 112b, the arrangement order of the convex portions 1122 and the concave portions 1123 is: depression 1123a, protrusion 1122a, depression 1123b, protrusion 1122b, depression 1123c, protrusion 1122c, depression 1123d, and protrusion 1122 d. Wherein, the longitudinal dimension (i.e. the dimension in the longitudinal direction of the second portion 112b, the same below) and the transverse dimension (i.e. the dimension perpendicular to the longitudinal direction, the same below) of the recess 1123a are equal to the longitudinal dimension and the transverse dimension of the protrusion 1122d, respectively, and the longitudinal dimension is L1; the longitudinal dimension and the lateral dimension of the recess 1123b are equal to the longitudinal dimension and the lateral dimension of the protrusion 1122c, respectively, and the longitudinal dimension is L3; the longitudinal dimension and the lateral dimension of the recess 1123c are equal to the longitudinal dimension and the lateral dimension of the protrusion 1122b, respectively, and the longitudinal dimension is L4; the longitudinal dimension and the lateral dimension of the recess 1123d are equal to the longitudinal dimension and the lateral dimension of the protrusion 1122a, respectively, and the longitudinal dimension is L2; wherein L4> L3> L2> L1. In other embodiments, at least one of the protrusions 1122 has a dimension in the longitudinal direction that is not equal to the dimension of the other protrusions in the longitudinal direction. It is noted that the portion of the protrusion 1122b adjacent to the recess 1123c is a line segment that bisects the longitudinal length of the protrusion 112 b. The first portion defines a center line perpendicular to the longitudinal direction a, and a distance (L2/2+ L3+ L4) from the center of any protrusion (e.g., 1122a) to the center line is equal to a distance (L2/2+ L3+ L4) from the center of any corresponding recess (1123d) to the center line, so that, on both sides of the center line, the positions of the protrusions 1122 and the positions of the recesses 1123 are in one-to-one correspondence. So configured, the first table unit 112 can form fit with the second table unit 114 with the same shape and size, and finally form a regular working surface in a rectangular shape.

The first stage unit 112 has a plurality of positioning holes 1101 penetrating the first working surface 1120, the positioning holes 1101 include n positioning holes 11011 disposed on the first portion 112a and n/2 positioning holes 11012 disposed on the second portion 112b, n is an even number greater than 0. The detent apertures 11011 of the first portion 112a are aligned with each other in the b-direction, forming a first set of detent apertures 1101a, and the detent apertures 11012 of the second portion 112b are also aligned with each other in the b-direction. Specifically, the positioning holes 11012 of the second portion 114 are disposed on the protruding

portions

1122a, 1122b and 1122c, and the protruding portion 1122d is not disposed with the second positioning holes 11012 due to its small size. Specifically, the positioning holes 11012 of the second portion 114 include a first positioning hole 11013a disposed in the first protrusion, two second positioning holes 11014a disposed in the second protrusion, and a third positioning hole 11015a disposed in the third protrusion.

As can be seen from fig. 4, in the direction b perpendicular to the longitudinal direction a, the positioning holes 11012 of the second portion 112b are symmetrical to the positioning holes 11011 of a part of the first portion 112a with respect to a straight line parallel to the longitudinal direction. Since the second stage unit 114 and the first stage unit 112 have the same structure, when they are mated, that is, when the second portions 112b of the two are fitted, the second positioning holes 11013a, 11013b, 11013c of the second stage unit 114 and the positioning holes 11012 of the second portion of the first stage unit 112 are aligned in the b direction and are shifted from each other in the a direction. In the direction b, the combination of the positioning holes 11012 of the second portion of the first table unit 112 and the positioning holes of the second portion of the second table unit 114 forms a new row of positioning holes having collinear centers, and the row of positioning holes is aligned with the positioning holes 11011 of the first portion 112a of the first table unit one by one. That is, the second portions 112b of the two first table units 112 and the second portion (not numbered) of the second table unit together form a second set of sprocket holes 1101b of another similar first set of sprocket holes 1101a, the second set of sprocket holes 1101b is identical to the first set of sprocket holes 1101a in arrangement (i.e., the hole pitch, the hole size, etc. are identical), and it can be said that the second set of sprocket holes 1101b is symmetrical to the first set of sprocket holes 1101a with respect to a line parallel to the direction b. When the table 100 is in the first state, the table unit 110 includes three sets of the first positioning holes 1101a, the second positioning holes 1101b of the first table unit 112 and the third positioning holes 1101c of the second table unit 114, which are identical. Three sets of

sprocket holes

1101a, 1101b, 1101c are longitudinally spaced, each set being equally spaced. Thus, the worktable 100 can clamp more workpieces at the same time, for example, the second set of the positioning holes 1101b and the first set of the positioning holes 1101a (or the third set of the positioning holes 1101c) with smaller spacing are selected when clamping the workpieces with shorter length (dimension perpendicular to the longitudinal direction); if a longer workpiece is clamped, the first set of sprocket holes 1101a and the third set of sprocket holes 1101c are selected with a larger pitch. This allows for better clamping stability while maximizing the use of the table unit 110.

Referring to fig. 9 to 12, in another embodiment, the workbench 100 further includes at least two clamping blocks 190, each clamping block 190 includes a pin 191 and a clamping portion 192, the pin 191 is inserted into the first positioning hole 1101 or the second positioning hole, and a clamping space is formed between the two clamping portions 192. The distance between the two positioning holes is predetermined in the longitudinal direction a. Taking the second set of positioning holes 1101b as an example, with reference to fig. 1, when the stage unit is in the first state, when the pins 191 are inserted into the first positioning holes 11013a of the first stage unit 112 and the third positioning holes 11015b of the second stage unit 114, a 2 × 4 inch clamping area is formed between the clamping portions 192; when the pins 191 are inserted into the first positioning holes 11013a of the first table unit 112 and the first positioning holes 11014a of the first table unit 112, which are far away from each other, a 2 × 8 inch clamping area is formed between the clamping portions 192; when the pins 191 are inserted into the third positioning holes 11015b of the second table unit 114 and the first positioning holes 11015a of the first table unit 112, which are far away from each other, a 2 × 10 inch clamping area is formed between the clamping portions 192; when the pin 191 is inserted into one second positioning hole 11014a of the first worktable unit 112 and a second positioning hole 11014b of the second worktable unit 114 which is far away, a 2 x 6 inch clamping area is formed between the clamping parts 192; when the pins 191 are inserted into one second positioning hole 11014b of the second table unit 114 and the first positioning hole 11013a of the first table unit 112, a 2 × 10 inch clamping area is formed between the clamping portions 192; when the pin 191 is inserted into one second positioning hole 11014a of the first table unit 112 and a second positioning hole 11014b of the second table unit 114, which is far away from the first positioning hole 11014a, a 2 × 6 inch clamping area is formed between the clamping portions 192. The other side of the center of the rotating shaft can form a clamping area of 2 × 6 inches and 2 × 8 inches as before, and the description is omitted. Thus, standard workpieces with the same size as 2 × 4, 2 × 6, 2 × 8, 2 × 10 and the like can be clamped. Therefore, no matter which side of two sides of the longitudinal length (defined by the longitudinal length direction of the first part) of the workbench unit is used for conveniently clamping the workpiece, and different habits of left-handed users or right-handed users are met.

Scales 1102 corresponding to the positioning holes 1101 are further arranged on the side of the positioning holes 1101, so that a user can intuitively adjust the clamping size conveniently. Figure 10 shows a view of a standard 2 x 4 timber 200 with the worktable holding a workpiece. Fig. 11 and 12 show schematic views of the worktable holding a standard 2 x 6 inch short workpiece 300 and a 2 x 8 inch workpiece 400, respectively, the workpieces in fig. 11 and 12 being shown transparent for the sake of viewing the corresponding dimensions.

Of course, depending on the structure of the protrusions 1122, if the sizes of the protrusions are equal (i.e., L1-L2-L3-L4), a part of the positioning holes just straddles the recesses of the

protrusions

1122 and 1123, that is, the positioning holes are half holes, and even if the positioning holes are formed in two half holes after being coupled to the table unit, such positioning holes are formed in two parts (with a slight displacement), which is unstable and causes a large error during positioning, and such positioning holes are meaningless. And the second set of positioning holes 1101b similar to the first positioning holes 11011 may be formed only when the sizes of the protrusions are not all equal.

Referring now to fig. 2 and 6, a rib 119 is provided on a side of the first table unit 112 facing away from the first working surface 1120 to enhance the supporting strength. The reinforcing rib 119 comprises a first rib portion 1191 parallel to the longitudinal direction, a second rib portion 1192 perpendicular to the first rib portion 1191, a third rib portion 1193 and a fourth rib portion 1194 forming an acute angle with the first rib portion 1191. In this embodiment, the first rib 1191, the third rib 1193, and the fourth rib 1194 form an angle of 45 degrees, and the third rib 1193 and the fourth rib 1194 are disposed perpendicularly. The first rib 1191, the second rib 1192, the third rib 1193 and the fourth rib 1194 intersect with each other, so that a plurality of shapes like a Chinese character 'mi' are formed at the lower side of the first table unit. The reinforcing ribs 119 in the shape of a Chinese character 'mi' can disperse stress on the workbench unit in four directions, so that the supporting strength is increased, and the service life of the workbench is prolonged.

In the present embodiment, the reinforcing rib 119 is formed only in the first portion 112a, and the second portion 112b is not additionally provided because it has a structure having a large strength (the structure is used to receive and support the rotation shaft 111, and thus requires a large strength).

Referring to fig. 4 and 5, the first portion 112a is provided with a recess 126 formed at a lower side thereof (a side to which the bracket is connected), and the recess 126 extends in the longitudinal direction a and penetrates a side surface 1127 of the first portion 112a and another side surface 1128 parallel to the side surface 1127.

The second portion 112b has a plurality of support holes 125 (fig. 3) for receiving the rotation shaft 111, the rotation shaft is rotatably supported by the first table unit 112 by being inserted into the support holes 125, and the second table unit 114 is identical to the first table unit 112 and thus supports the rotation shaft 111 in the same manner. In conjunction with fig. 2, the first table unit 112 further has a pressing portion 1145 fixed on the edge of the second portion 112a, the pressing portion 1145 is used for holding the free end of the rotating shaft and limiting the rotating shaft to only rotate. The other free end of the rotating shaft 111 is restricted by another pressing portion (not numbered) of the second table unit 114.

Referring to fig. 1 to 3, the first table unit 112 and the second table unit 114 are hinged to each other by a hinge 111 near the longitudinal edges of the respective second portions, so as to realize the relative rotation of the first table unit 112 and the second table unit 114, so that the table unit 110 can be unfolded or folded (and the first working surface 1120 and the second working surface 1140 of the first table unit 112 and the second table unit 114 form a horizontal top surface (i.e., a working surface 1100) for supporting a workpiece after being unfolded, the

protrusions

1122a, 1122b, 1122c, 1122d of the first table unit 112 are engaged with the recesses of the second table unit 114, the

recesses

1123a, 1123b, 1123c, 1123d of the first table unit 112 are engaged with the recesses of the second table unit 114, so as to form a complete, regular and seamless rectangular working surface 1100, the rotating shaft 111 may be integrally formed directly on the first table unit 112 or the second table unit 114 as long as the relative rotation between the two is ensured.

Referring to fig. 3, an axis of the rotating shaft 111 (i.e. an axis of relative rotation) is parallel to the longitudinal direction a of the first table unit 112, and in this embodiment, the axis is also parallel to the longitudinal direction of the second table unit 114. That is, the first table unit 112 and the second table unit 114 are both rotated in the longitudinal direction thereof.

Fig. 7 and 8 show the table 100 in a folded state, and the stand 120 is partially received by the table unit 110 after being folded. Referring to fig. 4, the first table unit 112 and the second table unit 114 rotate relatively around the rotating shaft 111 until the first table unit 112 and the second table unit 114 abut against each other, a bottom wall 1261 and two side walls 1262 of the recess 126 of the first table unit 112 and a bottom wall and side walls of the other recess corresponding to the second table unit are enclosed to form a rectangular rack housing cavity 140, two lengthwise ends of the rack housing cavity 140 are open, that is, the recess 126 of the first table unit 112 and the other recess of the second table unit 114 enclose the rack housing cavity 140. After the support 120 is folded, the support legs 122 are arranged in a substantially rectangular shape, the support legs 120 are held by the inner wall of the support placing chamber 140, and the support leg mounting seats are exposed, so that the support is limited in the circumferential direction (the direction perpendicular to the inner wall of the support placing chamber). The stand placement chamber 140 is also provided with a resilient non-slip pad 115 to limit movement of the stand along the support leg axis, i.e., to prevent the stand from sliding out of the opening.

With reference to fig. 8, in the extending direction of the first leg 1124 and the second leg 1125 of the first workbench unit 112, the lateral sizes of the two legs are gradually decreased along the extending direction, so that after the workbench unit 1100 is folded, the first leg 1124 and the second leg 1145 of the second workbench unit 114 are at least partially staggered and abutted against each other, thereby achieving form fit (i.e., a large portion is engaged with a small portion), i.e., the first workbench unit 112 and the second workbench unit 114 are abutted against each other and are limited against each other without relative movement, and ensuring the stability of the folded state of the workbench unit 110.

When the work bench units are in the folded state, the first leg 1124 of the first work bench unit 112 and the second leg 1145 of the second work bench unit 114 cooperate to form a first curved outer contour 11240, the second leg 1125 of the first work bench unit and the first leg 1144 of the second work bench unit cooperate to form a second curved outer contour 11250, the first curved outer contour 11240 connects the first side 1126 and the second side 1127, and the second curved outer contour 11250 connects the first side 1126 and the third side 1128, thereby forming a stable receiving structure.

Of course, if the holding bracket is to be stabilized, a connecting structure is required for the first table unit 112 and the second table unit 114 on the side away from the rotation axis. The workbench may further include a detachable connection member 160, the connection member 160 includes a main body 164 and connection portions 162 located at opposite sides of the main body, the connection portions 162 are in a hole shape, one sides of the first workbench unit 112 and the second workbench unit 114 far away from the rotation shaft are respectively provided with a pair of

columnar protrusions

1129, 1149, and the connection portions 162 are sleeved and connected to the

columnar protrusions

1129, 1149 to reversely rotate the first workbench unit 112 and the second workbench unit to be separated. The two protrusions 1129 (or between the two protrusions 1149) form the handle 118 therebetween. Instead of the connector 160 and the

protrusions

1129, 1149, the inner wall of the stent placement cavity 140 may directly hold the stent 120 by the holding force of the user holding the handle 118, which, of course, requires a greater force to be applied by the user and the user experience is relatively poor.

In addition, the protruding portions of the first and second working

table units

112 and 114 may be directly contacted with the ground as a support of the whole structure, and the handle 118 may be positioned at a certain height for the user to take.
