DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0021] See also Figure 1 to Figure 5 , a sand box with a C-type quick hook, comprising: A sand box 12, wherein an upper sand box 11 and a lower sand box 13 are respectively installed on the upper side and the lower side of the sand box 12, and reinforcing ribs 10 are fixed to the surfaces of both ends of the upper sand box 11, the sand box 12, and the lower sand box 13; The hook unit 2 is slidably connected to the surface of the reinforcing ribs 10 on the upper flask 11, the flask 12, and the lower flask 13, and is used to cooperate with the reinforcing ribs 10 to achieve the fixation of the upper flask 11, the flask 12, and the lower flask 13; The sliding unit 3 is slidably connected to the surface of the sand box 12 and connected to the hook unit 2 to drive the hook unit 2 to slide; The adjusting unit 4 is slidably connected to the sand box 12 and is slidably connected to the sliding unit 3, and is used to cooperate with the sliding unit 3 to achieve the engagement of the hook unit 2 and the adjustment of the engagement position.

[0022] In an embodiment of the present invention, when the upper sand box 11, the sand box 12, and the lower sand box 13 are fixed, the adjusting unit 4 is slid up and down, and the sliding unit 3 will drive the hook unit 2 to slide and adjust the position with the cooperation of the adjusting unit 4, so that the two groups of hook units 2 can fix the upper sand box 11, the sand box 12, and the lower sand box 13 at the same time, or fix the sand box 12 or one group of the upper sand box 11 (or the lower sand box 13) in pairs, which has the advantages of easy operation and easy adjustment of the number of fixed sand boxes.

[0023] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the hook unit 2 includes: The arc-shaped buckle 21 is connected to the surface of the reinforcing rib 10; The C-shaped hook 22 is slidably connected to the surfaces of the two groups of reinforcing ribs 10 and is engaged with the two groups of arc-shaped buckles 21 .

[0024] In this embodiment, when using the sand box 12 for casting, the lower sand box 13 is placed on the ground, and sand is added to the lower sand box 13 for casting. After the sand in the lower sand box 13 is compacted, the upper side of the lower sand box 13 is placed on the sand box 12, and sand is continued to be added to the sand box 12. Finally, the upper sand box 11 is closed on the upper side of the sand box 12.

[0025] When fixing the upper sand box 11, the sand box 12 and the lower sand box 13, the C-shaped hook 22 is slid on the surface of the two groups of reinforcing ribs 10 at the ends of the upper sand box 11 and the sand box 12 or the surface of the two groups of reinforcing ribs 10 at the ends of the sand box 12 and the lower sand box 13, so that the C-shaped hook 22 slides from the surface of the two groups of reinforcing ribs 10 to the side of the two groups of arc buckles 21, and then the upper sand box 11, the sand box 12 or the sand box 12, the lower sand box 13 can be limited and fixed under the action of the arc buckle 21 and the C-shaped hook 22 respectively.

[0026] like Figure 1As shown, two groups of C-shaped hooks 22 are installed, and four groups of arc-shaped clips 21 are installed. When the upper sand box 11, the sand box 12 and the lower sand box 13 need to be fixed at the same time, it is only necessary to slide one group of C-shaped hooks 22 to the surface of the two groups of arc-shaped clips 21 on the upper side, and slide the other group of C-shaped hooks 22 to the surface of the other two groups of arc-shaped clips 21. Thus, the upper sand box 11 and the sand box 12 can be fixed under the action of the upper group of C-shaped hooks 22 and the two groups of arc-shaped clips 21, and the sand box 12 and the lower sand box 13 can be fixed under the action of the lower group of C-shaped hooks 22 and the two groups of arc-shaped clips 21, thereby realizing the simultaneous fixation of the upper sand box 11, the sand box 12 and the lower sand box 13.

[0027] When the upper sand box 11 and the sand box 12 need to be fixed, or the sand box 12 and the lower sand box 13 need to be fixed, the two groups of C-shaped hooks 22 can be simultaneously slid to the surfaces of the upper two groups of C-shaped hooks 22, or the surfaces of the lower two groups of C-shaped hooks 22 (such as Figure 1 The upper sand box 11 and the sand box 12 or the sand box 12 and the lower sand box 13 can be fixed in pairs.

[0028] In one embodiment of the present invention, Figure 2 and Figure 5 As shown, the sliding unit 3 includes: The device frame 31 is fixed on the sand box 12, and the upper and lower end surfaces are respectively provided with an upper half slide groove 32 and a lower half slide groove 33; A vertical slot 37 is provided on the device frame 31, and its two ends are respectively connected to the ends of the upper half chute 32 and the lower half chute 33; The auxiliary upper half chute 321 is provided on the surface of the reinforcing rib 10 of the upper flask 11, is connected with the upper half chute 32, and forms a complete chute with the upper half chute 32; The auxiliary lower half chute 331 is provided on the surface of the reinforcing rib 10 on the lower flask 13, is connected with the lower half chute 33, and forms a complete chute with the lower half chute 33; The sliding member 34 is slidably connected in the vertical groove 37, the complete slide groove composed of the upper half slide groove 32 and the auxiliary upper half slide groove 321, and the complete slide groove composed of the lower half slide groove 33 and the auxiliary lower half slide groove 331; The sliding post 35 is fixed on the sliding member 34 , and the sliding post 35 is connected to the side of the C-shaped hook 22 through a connecting rod 36 .

[0029] In this embodiment, when the sand box 12 is closed on the upper side of the lower sand box 13 and the upper sand box 11 is closed on the upper side of the sand box 12, the upper half chute 32 and the auxiliary upper half chute 321 constitute a complete chute (hereinafter referred to as the upper chute), and the lower half chute 33 and the auxiliary lower half chute 331 also constitute a complete chute (hereinafter referred to as the lower chute).

[0030] When the sand box 12 and the lower sand box 13 need to be fixed, the sliding column 35 is slid through the adjustment unit 4, so that the sliding column 35 drives the sliding member 34 to slide in the downward groove toward the arc buckle 21. When the sliding column 35 slides, it can drive the C-shaped hook 22 connected to it to slide synchronously through the connecting rod 36, so that the C-shaped hook 22 will slide on the two groups of reinforcing ribs 10 on the surface of the sand box 12 and the lower sand box 13. When the sliding member 34 slides to the end of the downward groove, the C-shaped hook 22 will slide to the two groups of arc buckles 21 on the surface of the two groups of reinforcing ribs 10. Similarly, consistent with the above working process, another group of C-shaped hooks 22 can also slide to the other side of the two groups of arc buckles 21 (such as Figure 1 state), so that the flask 12 and the lower flask 13 are fixed by the engagement of the two groups of C-shaped hooks 22 and the two groups of arc-shaped buckles 21.

[0031] When the upper sand box 11 and the sand box 12 need to be fixed, and the working process of fixing the sand box 12 and the lower sand box 13 is the same, it is only necessary to slide the sliding post 35 by the adjusting unit 4, so that the sliding post 35 drives the sliding member 34 to slide in the lower sliding groove until the sliding member 34 slides to the connecting part of the lower sliding groove and the vertical groove 37. At this time, the sliding post 35 is slid upward, so that the sliding post 35 will drive the sliding member 34 to slide upward in the vertical groove 37 until the sliding member 34 slides to the connecting part of the vertical groove 37 and the upper sliding groove. At this time, the sliding post 35 is slid in the direction of the C-shaped hook 22, so that the sliding post 35 drives the sliding member 34 to slide in the upper sliding groove. When sliding, the sliding post 35 can drive the C-shaped hook 22 connected to it to slide synchronously through the connecting rod 36, so that the C-shaped hook 22 can slide on the two groups of reinforcing ribs 10 on the surfaces of the upper sand box 11 and the sand box 12, until the C-shaped hook 22 slides to the two groups of arc buckles 21 on the surfaces of the two groups of reinforcing ribs 10. Similarly, another set of C-shaped hooks 22 can also slide to the other side of the two sets of arc-shaped buckles 21 , so that the upper sand box 11 and the sand box 12 are fixed by the engagement of the two sets of C-shaped hooks 22 and the two sets of arc-shaped buckles 21 .

[0032] When it is necessary to fix the upper sand box 11, the sand box 12 and the lower sand box 13 at the same time, because there are two groups of C-shaped hooks 22, the working process is the same as the above, and only one group of C-shaped hooks 22 needs to be slid to the surface of the two groups of arc-shaped buckles 21 on the upper side, and the other group of C-shaped hooks 22 needs to be slid to the surface of the two groups of arc-shaped buckles 21 on the lower side, so that the upper sand box 11, the sand box 12 and the lower sand box 13 can be fixed at the same time.

[0033] In one embodiment of the present invention, Figure 5As shown, at least four groups of elastic beads 341 are slidably connected inside the sliding member 34; the ends of the elastic beads 341 are slidably connected to the inner walls of the upper slide groove, the lower slide groove or the vertical groove 37, respectively. When the sliding member 34 stops sliding, the elastic beads 341 in the sliding member 34 will press against the inner walls of the upper slide groove, the lower slide groove or the vertical groove 37, so that the sliding member 34 can be limited under the action of the elastic beads 341, thereby improving the stability of the sliding member 34 after sliding in the upper slide groove, the lower slide groove or the vertical groove 37, thereby improving the stability of the hook unit 2 after fixing the sand box. The elastic beads 341 can be specifically composed of springs and sliding beads, which will not be described in detail here.

[0034] In one embodiment of the present invention, Figure 1 As shown, the adjustment unit 4 includes: The limiting frame 41 is fixed on the surface of the device frame 31 and is slidably connected to the adjusting frame 42; An upper inclined groove 43 is provided on the adjustment frame 42, and the surface of the sliding column 35 is slidably connected in the upper inclined groove 43; The lower inclined groove 44 is provided on the adjustment frame 42, and the end thereof is connected to the upper inclined groove 43, and the surface of the sliding column 35 is slidably connected in the lower inclined groove 44; The adjustment hole 45 is formed on the surface of the adjustment frame 42 .

[0035] In this embodiment, the adjusting frame 42 is slid up and down so that the adjusting frame 42 slides in the two sets of limiting frames 41 . When the adjusting frame 42 slides, the upper inclined groove 43 and the lower inclined groove 44 on the surface thereof can be driven to slide synchronously.

[0036] When the adjustment frame 42 is slid upward, as shown in FIG. Figure 1 As shown, because the surface of the sliding column 35 is slidably connected in the lower inclined groove 44, the sliding column 35 will first slide in the lower inclined groove 44, and at the same time, the sliding column 35 will drive the sliding member 34 to slide in the lower groove in the direction away from the C-shaped hook 22 under the action of the lower inclined groove 44. When the sliding column 35 slides to the end of the lower inclined groove 44 close to the upper inclined groove 43, the sliding member 34 also slides to the connecting point of the lower groove and the vertical groove 37.

[0037] The adjusting frame 42 continues to slide upward. At this time, the sliding post 35 will drive the sliding member 34 to slide upward in the vertical slot 37 under the action of the end of the lower inclined slot 44, until the sliding member 34 slides to the uppermost end of the vertical slot 37, and the adjusting frame 42 continues to slide upward. At this time, the sliding post 35 will slide from the connection point between the upper inclined slot 43 and the lower inclined slot 44 to the lower inclined slot 44, so that the sliding post 35 will drive the sliding member 34 to slide in the upper slide slot toward the direction close to the C-shaped hook 22 under the action of the lower inclined slot 44. When sliding, the sliding post 35 can drive the C-shaped hook 22 to slide synchronously through the connecting rod 36 until the C-shaped hook 22 slides to the two groups of arc buckles 21 on the surfaces of the two groups of reinforcing ribs 10 where the upper sand box 11 and the sand box 12 are located, so that the upper sand box 11 and the sand box 12 will be fixed under the engagement of the C-shaped hook 22 and the two groups of arc buckles 21.

[0038] When the adjustment frame 42 is slid downward, in contrast to the above working process, the sliding column 35 will drive the sliding member 34 to slide in the upper sliding groove away from the C-shaped hook 22 under the push of the lower inclined groove 44, until the sliding member 34 slides to the upper end of the vertical groove 37, and the adjustment frame 42 continues to slide downward. At this time, the sliding member 34 will slide downward in the vertical groove 37, and finally the sliding column 35 will drive the sliding member 34 to slide in the lower sliding groove towards the C-shaped hook 22 under the push of the upper inclined groove 43 (such as Figure 1 state), until the C-shaped hook 22 slides onto the two groups of arc-shaped buckles 21 on the surfaces of the two groups of reinforcing ribs 10 where the sand box 12 and the lower sand box 13 are located, so that the sand box 12 and the lower sand box 13 will be fixed under the engagement of the C-shaped hook 22 and the two groups of arc-shaped buckles 21.

[0039] The adjusting unit 4 is provided with two groups, so that the upper sand box 11, the sand box 12, and the lower sand box 13 can be fixed at the same time, or the sand box 12 and one of the groups can be fixed in pairs through the hook unit 2. The surface of the adjusting frame 42 is provided with an adjusting hole 45, and the adjusting frame 42 can be moved by inserting a finger into the adjusting hole 45. The adjusting hole 45 can also be replaced by a handle, which is not limited here.

[0040] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, two groups of avoidance grooves 5 are formed on the reinforcing rib 10, and the two groups of C-shaped hooks 22 are respectively vertically slidably connected in the avoidance grooves 5. In this embodiment, when the sliding member 34 slides up and down in the vertical groove 37, the C-shaped hook 22 can slide in the avoidance groove 5, thereby preventing the reinforcing rib 10 from interfering with the up and down sliding of the C-shaped hook 22.

[0041] The working principle of the present invention is: when fixing the upper sand box 11, the sand box 12, and the lower sand box 13, the C-shaped hook 22 is slid on the surface of the two groups of reinforcing ribs 10 until the C-shaped hook 22 slides to the surface of the two groups of arc-shaped buckles 21, so that the upper sand box 11, the sand box 12, and the lower sand box 13 can be fixed under the action of the arc-shaped buckles 21 and the C-shaped hook 22.
