Detailed Implementation

[0027] To make the objectives, methods, and advantages of the embodiments of this utility model clearer, the methods in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0028] Example 1: As Figure 1As shown, an adjustable tray assembly suitable for a template support frame includes: a tray 1, a screw 2, and a riser 3. One end of the screw 2 is connected to the bottom wall of the tray 1, and the other end of the screw 2 is inserted into the riser 3. A limiting seat 4 is provided at one end of the riser 3 near the screw 2. The adjustable tray assembly also includes: an adjusting member 5 and a limiting member 6. The adjusting member 5 has a thread that mates with the screw 2, and the side wall of the adjusting member 5 has a wing 51 for gripping with claws. The limiting member 6 is connected to the wing 51 and has a degree of freedom of rotation about the central axis of the riser 3. When the screw 2 is inserted into the riser 3, the limiting member 6 is connected to the limiting seat 4, and the limiting seat 4 has at least one limiting bottom wall that abuts against the limiting member 6 in the longitudinal direction.

[0029] In the specific implementation process, the applicant applied for patent number CN222095973U on February 26, 2024, entitled "A wrench for installing and removing the top and bottom supports of a disc buckle bracket." The nut that mates with the aforementioned wrench has a wing 51 to cooperate with the clamping claws on the wrench to easily and effortlessly tighten the nut even in situations where the wrench has limited operating space. However, in the specific implementation process, since the template support frame, such as scaffolding, is composed of a large number of uprights, horizontal bars, and diagonal bars connected together, and a large number of uprights jointly support the support plate 1, the height of each upright should be as uniform as possible. However, the conventional operation of adjustable scaffolding is: first, tighten the nut so that the nut moves on the screw 2, thereby determining the exposed length of the screw 2, and then insert the screw 2 into the vertical pipe 3, with the nut abutting against the top wall of the vertical pipe 3. In the construction industry, most scaffolding is still erected manually, making it difficult to ensure that the uprights are of consistent length. Therefore, after placing the support plate 1, if it is found to be uneven or there is still a gap between the top of some uprights and the bottom of the support plate 1, fine adjustments are required. These adjustments typically require holding the screw rod 2 and bearing its weight with one's hand, which is relatively cumbersome and laborious. Based on the above, the applicant hopes to improve the structure of the adjustable support plate assembly to make the fine-tuning of the support frame quicker.

[0030] The core improvement in this embodiment lies in the vertical rod part of the support frame. The horizontal and diagonal rods connected to the vertical rod can be set in accordance with existing technology, and will not be described in detail in this embodiment.

[0031] The screw 2 and the riser 3 can be directly connected by a sleeve, a screw, or other methods; this embodiment does not impose specific limitations. The main body of the adjusting member 5 can adopt a nut structure, which is connected to the screw 2. This embodiment directly improves the adjusting member 5 with the wing 51 by setting a limiting member 6, and then setting a limiting seat 4 on the riser 3 to cooperate with the limiting member 6. The limiting seat 4 not only restricts the upward movement of the nut, but also ensures that the nut can rotate while the limiting member 6 is connected to the limiting seat 4.

[0032] As an example, during operation, if the height of one or more screws 2 needs fine-tuning before connecting the support plate 1, connect the limiting piece 6 and the limiting seat 4, and then rotate the adjusting piece 5 in the desired direction. At this time, the lower part of the adjusting piece 5 directly abuts against the riser 3, thus preventing it from moving downwards. With the cooperation of the limiting piece 6 and the limiting seat 4, the adjusting piece 5 also cannot move upwards. Therefore, the adjusting piece 5 no longer has longitudinal freedom of movement. Rotating the adjusting piece 5 can drive the screws 2 to rise and fall. The screws 2 are mainly used to appropriately adjust the height of the support frame. Their length is generally not too large. Typically, when the diameter of the riser 3 is 42mm, the exposed length of the screw 2 is no more than 200mm; when the diameter of the riser 3 is greater than or equal to 48.3mm, the exposed length of the screw 2 is no more than 500mm.

[0033] In this embodiment, the structure of the limiting member 6 and the limiting seat 4 can be varied, as long as the above operation can be achieved. For specific implementation methods of the limiting member 6 and the limiting seat 4, please refer to the following embodiments.

[0034] For a detailed implementation method, please refer to Example 2 and... Figure 2 .

[0035] Example 2: This example provides a specific implementation of the limiting member 6 and the limiting seat 4, as follows: Figure 2 As shown, the limiting seat 4 includes: a ring body 401 and a first threaded rod 402. The ring body 401 is sleeved on the riser 3, and the inner wall of the ring body 401 is slidably connected to the outer wall of the riser 3. The bottom end of the first threaded rod 402 is connected to the ring body 401. The limiting member 6 includes: a second threaded rod 601, and the top end of the second threaded rod 601 is connected to the wing 51. The adjustable support plate assembly also includes: a threaded cylinder 7, with the first threaded rod 402 and the second threaded rod 601 respectively disposed on both sides of the length direction of the threaded cylinder 7. The threaded cylinder 7 is connected to the first threaded rod 402 and / or the second threaded rod 601.

[0036] In specific implementation, the ring 401 can be circular. For example... Figure 2 As shown, a slider is provided on the inner ring wall of the ring body 401, and a groove is provided on the outer wall of the riser 3 to achieve a rotatable connection between the ring body 401 and the riser 3. Before the screw 2 is inserted into the riser 3, the threaded cylinder 7 can be connected to either the first threaded rod 402 or the second threaded rod 601. It should be noted that after the screw 2 is inserted into the riser 3, there is a certain gap between the first threaded rod 402 and the second threaded rod 601. At this time, by rotating the threaded cylinder 7, the screw 2 can be simultaneously connected to both the first threaded rod 402 and the second threaded rod 601. Before the screw 2 is inserted into the riser 3, the free end of either the first threaded rod 402 or the second threaded rod 601 can be flush with the end of the threaded cylinder 7.

[0037] As an example, before the screw 2 is connected to the riser 3, the threaded cylinder 7 is connected to the first threaded rod 402. At this time, the limiting bottom wall refers to the threaded wall inside the threaded cylinder 7, which restricts the movement of the second threaded rod 601. During operation, the connection of the threaded cylinder 7 can be selectively implemented. When it is necessary to fine-tune the height of the screw 2 and restrict the upward movement of the adjusting member 5, the threaded cylinder 7 is rotated so that the threaded cylinder 7 is simultaneously connected to the first threaded rod 402 and the second threaded rod 601.

[0038] For a detailed implementation method two, please refer to Examples 3-5 and... Figure 3 .

[0039] Example 3: This example provides a specific implementation of the second type of limiting member 6 and limiting seat 4, such as... Figure 3 As shown, the limiting member 6 includes a limiting rod 611 and a limiting ring 612. The top end of the limiting rod 611 is rotatably connected to the wing 51, and the end of the limiting rod 611 away from the wing 51 is provided with an external thread. The limiting ring 612 is provided with an internal thread that mates with the external thread. When the limiting rod 611 is in a vertical state, at least a portion of the orthographic projection of the limiting ring 612 toward the wing 51 falls on the limiting seat 4.

[0040] In the specific implementation process, the limiting ring 612 can be a nut. In the initial state, the limiting ring 612 can be located at the end of the limiting rod 611 to prevent the side wall of the limiting seat 4 from abutting against the limiting ring 612 when the limiting rod 611 rotates from a horizontal to a vertical position. After inserting the screw 2 into the riser 3, the limiting rod 611 can be rotated to a vertical position, and then the limiting ring 612 can be adjusted so that it abuts against the limiting seat 4. To reduce the influence of the limiting seat 4 on the limiting ring 612, the bottom wall of the limiting seat 4 can be made of a relatively smooth material, such as glass. Since the limiting rod 611 needs to extend below the limiting seat 4, in order to avoid the limiting rod 611 and the limiting seat 4 restricting each other when connecting the screw 2 and the riser 3, this embodiment rotatably connects the limiting rod 611 to the wing 51. That is, when connecting the screw 2 and the riser 3, the limiting rod 611 can change its position by rotation, thereby preventing the limiting rod 611 from obstructing the screw 2 from being inserted into the riser 3.

[0041] As an example, the limiting seat 4 can be annular, and the limiting seat 4 and the riser 3 can be fixedly connected. When the structure of the limiting member 6 and the limiting seat 4 in this embodiment is adopted, the limiting bottom wall refers to the bottom wall of the limiting seat 4 that abuts against the limiting ring 612.

[0042] Example 4: To ensure that the limiting rod 611 can maintain a stable horizontal state, improvements were made based on Example 3, such as... Figure 3As shown, in this embodiment, the limiting rod 611 is provided with a magnetic part 6111, and the wing 51 is provided with a magnetic part 4111 that cooperates with the magnetic part 6111.

[0043] In specific implementation, the magnetic part 6111 can be a magnet, and the magnetic part 4111 can be made of a material that can be attracted by a magnet, such as iron, cobalt, nickel, or alloys containing the aforementioned materials. The magnetic force between the magnetic part 6111 and the magnetic part 4111 needs to stably support the horizontally positioned limiting rod 611, but it should not be too large, as this would affect the release of the horizontal position of the limiting rod 611. The specific size can be set according to the weight and length of the limiting rod 611, etc., and is not limited in this embodiment.

[0044] Example 5: To better realize the setting of the limit rod 611, improvements were made based on Example 4, such as... Figure 3 As shown, in this embodiment, the wing 51 is provided with a receiving groove 411 on the side near the limiting seat 4, the limiting rod 611 is rotatably connected to the groove wall of the receiving groove 411, and the magnetic part 4111 is provided on the top wall of the receiving groove 411.

[0045] In the specific implementation process, since the limiting rod 611 needs to be rotatably connected to the wing 51, this embodiment sets up a receiving groove 411, which not only allows the rotating shaft to be set on the groove wall of the receiving groove 411, facilitating the installation of the limiting rod 611, but also allows the receiving groove 411 to directly provide clearance space when the limiting rod 611 rotates, so that the limiting rod 611 can rotate to a horizontal state and be magnetically connected to the groove wall of the receiving groove 411.

[0046] For a detailed implementation method three, please refer to Examples 6-9 and... Figures 4-7 .

[0047] Example 6: This example provides a third implementation of the limiting member 6 and the limiting seat 4, such as... Figure 4-6 As shown, the limiting member 6 includes: a rotating frame 621, which is rotatably connected to the wing 51 and surrounds the wing 51. The rotating frame 621 is provided with a limiting block 622. The side wall of the limiting seat 4 is provided with an annular groove 421 that cooperates with the limiting block 622. When the rotating frame 621 is in a vertical state, the limiting block 622 is located in the annular groove 421.

[0048] In specific implementation, the rotating frame 621 can be as follows: Figure 5As shown, the overall shape is U-shaped. In this embodiment, a limiting block 622 is provided in the rotating frame 621. Through the cooperation of the limiting block 622 and the annular slide groove 421, the rotating frame 621 can rotate around the limiting seat 4. When using the limiting member 6 and the limiting seat 4 structure of this embodiment, the bottom wall of the limiting member is the upper side wall of the annular slide groove 421. Before installing the screw 2 and the riser 3, the claws on the wrench can clamp the side wall of the wing 51 or the side wall of the rotating frame 621. After the screw 2 is inserted into the riser 3, the rotating frame 621 rotates, causing the limiting block 622 to enter the annular slide groove 421. The sliding of the limiting block 622 in the annular slide groove 421 can prevent the limiting seat 4 from restricting the rotation of the adjusting member 5. In order to reduce the obstruction of the annular slide groove 421 to the movement of the limiting block 622, a ring of balls arranged in annularly as shown in the figure can be provided in the annular slide groove 421. Of course, balls can also be provided on the top wall of the limiting block 622. When the structure of the limiting member 6 and the limiting seat 4 in this embodiment is adopted, the limiting bottom wall refers to the side wall of the annular groove 421.

[0049] Example 7: To ensure that the limiting block 622 can accurately enter the annular groove 421 when the rotating frame 621 rotates, improvements were made based on Example 6, such as... Figure 7 As shown, in this embodiment, the limiting block 622 is provided with a first arc wall 6221, and the center of the circle corresponding to the first arc wall 6221 is located on the central axis of the rotating frame 621.

[0050] In the specific implementation process, it can be as follows: Figure 7 As shown, the groove wall of the annular slide 421 is set to be an arc-shaped wall that matches the shape of the limiting block 622. The setting of the first arc wall 6221 enables the limiting block 622 to smoothly enter the annular slide 421 when the rotating frame 621 rotates, while ensuring that the upper side wall of the annular slide 421 restricts the upward movement of the limiting block 622.

[0051] Example 8: To simplify the connection operation between screw 2 and riser 3, improvements were made based on Example 7, such as... Figure 7 As shown, in this embodiment, the limiting block 622 is further provided with a second arc wall 6222, which is disposed opposite to the first arc wall 6221. The center of the second arc wall 6222 is located on the side of the second arc wall 6222 that is close to the first arc wall 6221. The limiting seat 4 is provided with a third arc wall 422. During the rotation of the rotating frame 621, there is at least one state in which the second arc wall 6222 abuts against the third arc wall 422.

[0052] In the specific implementation process, when inserting the screw 2 into the riser 3, such as Figure 7As shown, the limiting block 622 will contact the top wall of the limiting seat 4. In order to reduce the process of manually rotating the rotating frame 621, this embodiment is provided with a second arc wall 6222 and a third arc wall 422. Through the cooperation of the two, the limiting block 622 is subjected to force when it abuts against the limiting seat 4, thereby causing the rotating frame 621 to rotate in a direction away from the limiting seat 4. There is no need to manually rotate the rotating frame 621, which simplifies the installation operation of the screw 2 and the riser 3.

[0053] Example 9: To facilitate the rotation of the rotating frame 621, improvements were made based on Example 8, such as... Figure 7 As shown, in this embodiment, the center of the circle corresponding to the third arc wall 422 and the center of the circle corresponding to the second arc wall 6222 are respectively located on both sides of the third arc wall 422.

[0054] In specific implementation, when the centers of the circles corresponding to the second arc wall 6222 and the third arc wall 422 are respectively located on both sides of the third arc wall 422, such as Figure 7 As shown by the straight arrow, the force direction of the second arc wall 6222 is more offset from that of the limiting seat 4, making the rotating frame 621 more prone to problems such as... Figure 7 Autonomous rotation in the direction of the arrow in the middle arc.

[0055] Example 10: To improve the clamping stability of the wrench's jaws, improvements were made based on Examples 1-9, such as... Figure 8 As shown, in this embodiment, the wing 51 includes a horizontal plate 511 and a side plate 512, and the side plate 512 is provided at both ends of the horizontal plate 511 in the width direction.

[0056] In practice, the side plate 512 increases the clamping area of ​​the claw and the wing 51. At the same time, the presence of the side plate 512 makes the installation of the rotating frame 621, the limiting rod 611, etc. simpler, and the rotating shaft can be directly set on the side plate 512.

[0057] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
