Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of brackets, and particularly relates to an adjustable bracket. Background Art
[0002] In the operation of modern industrial equipment, the installation and fixation of display accessories are crucial for ensuring operation efficiency and safety. These accessories, including display screens and indicator lights, need to be placed in stable and easily observable positions so that operators can clearly read information. To meet this requirement, a special trolley is commonly used in industrial equipment to carry these display accessories and integrate various control components. This trolley is usually movable to improve portability.
[0003] However, in a complex environment such as an industrial workshop, some existing trolleys adopt non-adjustable display accessory brackets to improve stability. Although this design ensures the firmness of the accessories, it lacks flexibility and cannot adapt to different viewing or operation requirements.
[0004] On the other hand, some adjustable brackets adopt a structure similar to a damper, allowing a certain degree of tilt angle adjustment. However, in the complex environment of an industrial workshop, especially after being collided, the angle is prone to change, which is not conducive to maintaining the stability of the display accessories. Therefore, this type of adjustable bracket is less used in practical applications.
[0005] In summary, there is a lack of a display accessory bracket in the existing technology that can both achieve angle adjustment and maintain angle stability. Content of the Utility Model
[0006] In view of this, the utility model provides an adjustable bracket. The utility model can ensure that the angle will not easily shift after adjustment through the rigid connection between the limit port and the limit rod, improving the stability of angle adjustment.
[0007] To solve the above technical problems, the utility model provides an adjustable bracket, including a support and an adjustment component. A connection seat is arranged in the middle of the support through the adjustment component. The adjustment component includes a rotating column fixedly connected to the middle of the connection seat. Two push plates are slidably connected to the middle of the rotating column. On one side of each push plate far away from the middle of the rotating column, a plurality of limit rods arranged in a circular array around the central axis of the rotating column are fixedly connected. A plurality of limit ports arranged in a circular array around the central axis of the rotating column are opened on both sides of the support and the connection seat. The length of the limit rod is greater than the length of the support. Through the rigid connection between the limit port and the limit rod, it is ensured that the angle will not easily shift after adjustment, improving the stability of angle adjustment.
[0008] The adjusting assembly further includes a plurality of guide rods fixedly connected to one side of the push plate close to the center of the rotating column. The guide rods are distributed in an annular array around the rotating column. The guide rods are all slidably connected to the other push plate. A return spring is sleeved on the rod bodies of the guide rods located between the two push plates. That is, through the automatic reset of the return spring, the steps of angle adjustment are reduced.
[0009] Guide assemblies are provided in the middle parts of the rotating columns. The guide assemblies include guide cylinders fixedly connected to the ends of the guide rods away from the push plates. The guide cylinders are all slidably connected to the rotating columns. That is, the stability of the sliding connection between the rotating column and the guide cylinder is enhanced, ensuring accurate positioning during the rotation process.
[0010] A plurality of guide grooves arranged in an annular array are provided in the middle parts of the rotating columns. A plurality of guide blocks arranged in an annular array are fixedly connected to the inner walls of the guide cylinders. One ends of the guide blocks close to the rotating columns are all slidably connected to the middle parts of the adjacent guide grooves. That is, the matching accuracy between the guide cylinder and the rotating column is improved, enhancing the guiding performance of the entire adjusting assembly.
[0011] The guide assembly further includes first arc-shaped grooves opened on both sides of the support. Second arc-shaped grooves are opened on both sides of the connecting seat. Columns are fixedly connected to both ends of the first arc-shaped grooves. The middle parts of the columns are all located in the middle parts of the second arc-shaped grooves on the same side. That is, the rotation angle of the connecting seat is limited, enhancing the safety of the bracket.
[0012] Limit assemblies are provided on both sides of the middle parts of the rotating columns. The limit assemblies include a plurality of limit grooves opened in the rotating columns. Limit posts are slidably connected to the middle parts of the limit grooves. Limit springs are sleeved on the column bodies of the limit posts located in the limit grooves. That is, it ensures the stable sliding of the limit posts in the limit grooves, and at the same time the limit springs provide support for the limit posts.
[0013] The limit assembly further includes bayonets opened in the middle parts of the guide cylinders. The tops of the limit posts are all slidably connected to the adjacent bayonets. That is, the stability of the bracket during the adjustment process is enhanced, preventing the accidental retraction of the limit rods.
[0014] A plurality of support plates are fixedly connected to the middle parts of the rotating columns. The middle parts of the limit rods are all slidably connected to the adjacent support plates. That is, it provides stable support for the limit rods, avoiding the shaking caused by the excessive length of the limit rods.

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will combine the accompanying drawings of the embodiments of the present utility model Figures 1-5 to clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are some, rather than all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model fall within the scope of protection of the present utility model.
[0030] As Figures 1-5 shown: This embodiment provides an adjustable bracket, which includes a support 100 and an adjustment assembly 200. A connection seat 101 is arranged in the middle of the support 100 through the adjustment assembly 200. A plurality of connection ports are provided on one side of the connection seat 101, and various display accessories can be connected through the connection ports. The adjustment assembly 200 includes a rotating column 201 fixedly connected to the middle of the connection seat 101. Two push plates 202 are slidably connected to the middle of the rotating column 201. On one side of each push plate 202 away from the middle of the rotating column 201, a plurality of limiting rods 203 are fixedly connected and arranged in an annular array around the central axis of the rotating column 201. A plurality of limiting ports 204 are provided on both sides of the support 100 and the connection seat 101 and are arranged in an annular array around the central axis of the rotating column 201. The limiting ports 204 of the support 100 and the connection seat 101 are arranged in one-to-one correspondence. The shape of the limiting port 204 is the same as that of the limiting rod 203. The length of the limiting rod 203 is greater than the length of the support 100;
[0031] During installation, place the connection seat 101 in the middle of the support 100, and make the limiting ports 204 of the support 100 and the connection seat 101 coincide. At this time, pull the push plate 202 to move towards the middle of the rotating column 201 to separate the limiting rod 203 from the limiting port 204. At this time, rotate the connection seat 101 to adjust the angle of the connection seat 101. After the angle is adjusted, push the push plate 202 to drive the limiting rod 203 to insert into the adjacent limiting port 204, and connect the limiting ports 204 of the support 100 and the connection seat 101 in series, so that the connection seat 101 and the support 100 are connected together, and the angle of the connection seat 101 is restricted by the limiting rod 203, so as to restrict the angle of the display accessory. The limiting rod 203 can prevent the display accessory from deviating in angle when receiving collision or heavy touch clicks. The fixed effect on the connection seat 101 and the support 100 is effectively improved through a plurality of limiting rods 203;
[0032] When adjusting the angle, by pushing the push plate 202 towards the middle of the rotating column 201, the limiting rod 203 can be driven to separate from the limiting port 204. At this time, rotate the rotating column 201 and drive the connecting seat 101 to rotate around the axis of the rotating column 201. Until the angle of the connecting seat 101 is adjusted, align the limiting port 204 of the connecting seat 101 with the nearest adjacent limiting port 204 on the support 100. At this time, push the push plate 202 in the reverse direction, which will drive the limiting rod 203 to be inserted into the limiting port 204 again, completing the connection and fixation of the connecting seat 101 and the support 100. Through the annular array of limiting ports 204, the angle adjustment range of the connecting seat 101 is effectively guaranteed, enabling the connecting seat 101 to adjust the angle according to the specific usage scenario, and through the rigid connection between the limiting port 204 and the limiting rod 203, it is ensured that the angle will not easily shift after adjustment, effectively improving the controllability of angle adjustment.
[0033] The adjusting assembly 200 is as Figure 1 、 2 、shown in Figure 3.
[0034] The adjusting assembly 200 further includes a plurality of guide rods 205 fixedly connected to the side of the push plate 202 close to the center of the rotating column 201. The guide rods 205 are distributed in an annular array around the rotating column 201. The guide rods 205 are all slidably connected to the other push plate 202. A return spring 206 is sleeved on the rod bodies of the guide rods 205 located between the two push plates 202.
[0035] When the two push plates 202 drive the limiting rods 203 to separate from the limiting ports 204 respectively, the two push plates 202 approach each other, compressing the return spring 206. When the angle is adjusted, release the push plate 202. Under the elastic return of the return spring 206, the push plate 202 will move towards the end far from the middle of the rotating column 201, thereby driving the limiting rod 203 to be inserted into the adjacent limiting port 204. Through the automatic reset of the return spring 206, the steps of angle adjustment are reduced, and there is no need for the operator to push the push plate 202 again. Through multiple return springs 206, a uniform thrust can be generated on the push plate 202, avoiding uneven force on the push plate 202 and causing the limiting rod 203 to shift and fail to insert into the limiting port 204.
[0036] The guiding assembly 300 is as Figure 2 、 3 、shown in Figure 4.
[0037] Guiding assemblies 300 are provided in the middle of the rotating column 201. The guiding assembly 300 includes a guiding cylinder 301 fixedly connected to the end of the guide rod 205 far from the push plate 202. The inner diameters of the guiding cylinders 301 are all equal to the outer diameter of the rotating column 201. The guiding cylinders 301 are all slidably connected to the rotating column 201.
[0038] When the push plate 202 moves, it will drive the adjacent guide rod 205 to move, and then cause the guide cylinder 301 to move along the rotating column 201. Through the guide cylinder 301, it is possible to further prevent the push plate 202 from shifting during movement, improving the quality of the limiting rod 203 automatically inserting into the limiting port 204.
[0039] The guide block 303 is as Figure 4 shown.
[0040] A plurality of guide grooves 302 are provided in the middle of the rotating column 201 and are arranged in an annular array around the central axis of the rotating column 201. A plurality of guide blocks 303 are fixedly connected to the inner wall of the guide cylinder 301 and are arranged in an annular array around the central axis of the rotating column 201. One end of the guide block 303 close to the rotating column 201 is slidably connected to the middle of the adjacent guide groove 302.
[0041] When the push plate 202 moves, it may rotate, causing the limiting rod 203 to not accurately insert into the limiting port 204. Through the guide groove 302, the moving direction of the guide block 303 can be effectively guided, and then the moving directions of components such as the guide cylinder 301 and the guide column push plate 202 are restricted, thus preventing the push plate 202 from driving the limiting rod 203 to rotate.
[0042] The first arc-shaped groove 304 is as Figure 1 , 5 shown.
[0043] The guide assembly 300 further includes first arc-shaped grooves 304 provided on both sides of the support 100. Second arc-shaped grooves 305 are provided on both sides of the connecting seat 101. The centers of the first arc-shaped grooves 304 and the second arc-shaped grooves 305 coincide. The length of the second arc-shaped groove 305 is greater than that of the first arc-shaped groove 304. Both ends of the first arc-shaped groove 304 are fixedly connected with clamping posts 306. The middle parts of the clamping posts 306 are located in the middle of the second arc-shaped grooves 305 on the same side. The diameter of the clamping posts 306 is equal to the width of the second arc-shaped groove 305. The width of the second arc-shaped groove 305 is the same as the width of the first arc-shaped groove 304.
[0044] When the connecting seat 101 rotates, it will drive the second arc-shaped groove 305 to rotate. When the second arc-shaped groove 305 rotates to a certain angle, the end of the second arc-shaped groove 305 will contact the adjacent clamping post 306, thereby restricting the excessive rotation of the connecting seat 101. Since the limiting ports 204 are arranged in an annular array, if the rotation angle of the connecting seat 101 is not restricted, the connecting seat 101 will rotate excessively and collide with the support 100 or other components. Through the restriction of the second arc-shaped groove 305 and the clamping post 306, the rotation angle of the connecting seat 101 can be effectively restricted, ensuring the safety and stability of the connecting seat 101.
[0045] The limiting component 400 is as follows Figure 4 shown
[0046] Limiting components 400 are provided on both sides of the middle part of the rotating column 201. The limiting component 400 includes a plurality of limiting grooves 403 opened on the rotating column 201. Limiting columns 402 are slidably connected to the middle parts of the limiting grooves 403. Limiting springs 404 are sleeved on the columns of the limiting columns 402 located in the limiting grooves 403. The diameter of the limiting spring 404 is larger than the diameter of the bottom of the limiting column 402 and smaller than the diameter of the top of the limiting column 402;
[0047] Before the angle adjustment is completed, the push plate 202 will be pushed by the return spring 206 and finally drive the guide cylinder 301 to contact the top of the limiting column 402 and be limited. The excessive displacement of the push plate 202 can be avoided through the limiting column 402. When the push plate 202 is limited, the other side of the push plate 202 is continuously subjected to the elastic force of the return spring 206. Through such two-directional restrictions, the push plate 202 cannot easily generate displacement, thus ensuring the position stability of the push plate 202 and the limiting rod 203.
[0048] The bayonet 401 is as follows Figure 4 shown
[0049] The limiting component 400 further includes a bayonet 401 opened in the middle of the guide cylinder 301. The tops of the limiting columns 402 are slidably connected to the adjacent bayonets 401;
[0050] When pushing the limiting rod 203 to insert into the bayonet 401, press the limiting column 402 to move the limiting column 402 downward. When the guide cylinder 301 drives the bayonet 401 to move to the top of the limiting column 402, the limiting column 402 moves upward and inserts into the bayonet 401 under the reset of the return spring 206, thereby limiting the guide cylinder 301 and the push plate 202. Through the bayonet 401, not only the continuous movement of the push plate 202 and the guide cylinder 301 is blocked, but also their retraction is avoided, providing more directional position restrictions. In this way, it can be avoided that the limiting rod 203 is retracted due to impact and the separation of the limiting rod 203 from the bayonet 401. When the position of the limiting rod 203 needs to be adjusted, press the limiting column 402 to make the guide cylinder 301 lose its limit and then the adjustment can be carried out.
[0051] Some devices set a fulcrum in the middle of the two push plates 202 and springs are respectively arranged on both sides of the fulcrum to push the push plates 202 respectively. By setting the limiting component 400 in this device, a single return spring 206 can apply elastic forces to both push plates 202, thereby reducing the usage amount of the return spring 206 and improving the integration degree of this device.
[0052] The support plate 102 is as follows Figure 1 、 2 as shown in Figures 3 and 5
[0053] A plurality of support plates 102 are fixedly connected to the middle of the rotating column 201, and the middle of the limiting rod 203 is slidably connected to the adjacent support plates 102;
[0054] When the limiting rod 203 is moving, the support plate 102 always provides stable support for the middle of the limiting rod 203 to prevent the limiting rod 203 from being too long and causing the end to shake greatly, thereby causing the limiting rod 203 to fail to connect with the limiting opening 204.
[0055] Working principle:
[0056] The operator pulls the push plate to move toward the middle of the rotating column to separate the limit rod from the limit opening. At this time, the connecting seat can rotate around the axis of the rotating column and rotate the connecting seat to the required angle. At this time, the cooperation of the guide rod and the guide cylinder ensures the accurate movement of the push plate and the limit rod to avoid offset. After adjusting the angle, release the push plate, and the reset spring rebounds to push the push plate to drive the limit rod to insert into the adjacent limit opening, thereby fixing the angle of the connecting seat. The design of the first arc groove and the clamping column limits the rotation angle of the connecting seat to prevent collision caused by excessive rotation. The limit groove and limit column in the limit assembly, as well as the design of the clamping port, further enhance the stability of the bracket and prevent the limit rod from retracting or offsetting when hit. The support plate provides stable support for the limit rod to prevent shaking caused by excessive length of the limit rod, thereby ensuring accurate docking with the limit opening.
[0057] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
[0058] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
