Description

Technical Field

[0001] This utility model relates to the technical field of stationery, and more specifically to a posture corrector with a quick-change panel. Background Technology

[0002] Posture correctors are practical products for people who spend long hours studying or working at a desk. They can correct poor posture such as leaning forward or slouching, and prevent neck problems, vision problems, and hunchback caused by poor posture. However, current posture correctors only have a single-function writing pad panel that cannot be replaced, failing to meet diverse customer needs. Furthermore, if the panel is damaged during use or becomes uneven due to material aging or other reasons, the entire posture corrector must be replaced, which is very uneconomical. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a posture corrector with a quick-change panel. Customers can choose the panel according to their own needs and quickly change it themselves, without having to replace the entire posture corrector just to change the panel. This greatly improves practicality and economy, and the operation of changing the panel is simple and convenient.

[0004] The technical solution of this utility model is to provide a posture corrector with a quick-change panel, including a pad portion, a chest support provided on the front side of the pad portion, the pad portion including a panel support and a panel assembly, the panel assembly being detachably mounted on the panel support, and a locking assembly provided on the panel support, the locking assembly being used to lock the panel assembly onto the panel support; the locking assembly includes a locking main component, a locking head provided at the front end of the locking main component, and an elastic element provided between the locking main component and the panel support, the elastic element being used to push the locking main component to insert the locking head into or abut against the panel assembly to lock the panel assembly; pushing the locking main component in the opposite direction to compress the elastic element can disengage the locking head from the panel assembly to unlock the panel assembly.

[0005] Compared with the prior art, the quick-change panel posture corrector of this utility model has the following advantages: the panel assembly is detachable from the panel support, so customers can select and replace the panel according to their own needs; the operation of replacing the panel is simple and convenient. Just push the locking main component in the opposite direction to compress the elastic element so that the locking head disengages from the panel assembly, thereby unlocking the panel assembly, removing the old panel assembly, and replacing it with the new panel assembly, and locking the newly replaced panel assembly with the locking component; customers no longer need to replace the entire posture corrector just to replace the panel, which greatly improves practicality and economy.

[0006] Preferably, the locking assembly includes a press cover, which is positioned on the panel support and can slide up and down. A pressure post is provided on the lower side of the press cover. The main locking component has a driven inclined surface, and the lower bottom surface of the pressure post is slidably in contact with the driven inclined surface. When the press cover is pressed downward, the pressure post can drive the driven inclined surface to slide, causing the main locking component to compress the elastic element. The elastic element rebounds, allowing both the main locking component and the press cover to reset. With this structure, pressing the press cover is sufficient to unlock the panel assembly, and releasing the press cover is sufficient to reset and lock the panel assembly.

[0007] Preferably, the lower surface of the pressure column is configured as a driving inclined surface, which slides in contact with the driven inclined surface. This structure increases the contact area between the pressure column and the driven inclined surface, improves the ability of the pressure column to drive the driven inclined surface to slide, and avoids adhesion between the pressure column and the driven inclined surface due to the small force-bearing area.

[0008] Preferably, the main locking component is provided with a pressure post limiting groove, and the driven inclined surface is disposed in the pressure post limiting groove, with the lower end of the pressure post being limited within the pressure post limiting groove. This structure prevents the main locking component from suddenly protruding outwards due to elastic force and the pressure of the pressing cover, thus avoiding separation between the main locking component and the pressing cover.

[0009] Preferably, the panel support is provided with a latch mounting groove, the lower part of the latch main component is inserted into the latch mounting groove, and the latch mounting groove has an opening on the side opposite to the panel assembly, through which the latch head can extend or retract; a limiting seat is provided on the groove wall opposite to the opening of the latch mounting groove, one end of the elastic element is limited on the limiting seat, and the latch main component is provided with a spring groove opposite to the limiting seat, the other end of the elastic element is limited in the spring groove. This structure is simple and ensures the stability of the latch assembly.

[0010] Preferably, the latch mounting groove has sliding grooves on the groove walls on both sides of the opening; the press cover has sliding buckles on both sides, with the two sliding buckles located on the two outer sides of the latch main component and respectively limited to sliding up and down within the corresponding sliding grooves. With this structure, the sliding grooves guide the up and down sliding of the press cover, preventing the press cover from moving horizontally and causing the latch main component to fail to unlock the panel assembly.

[0011] Preferably, each of the two sliding grooves is provided with a limiting crossbar, and the lower end of each sliding buckle is provided with a buckle head, which is limited below the limiting crossbar. With this structure, the pressing cover can be lifted and moved upward to reset during the reset process of the main locking component. The limiting crossbar limits the buckle head, which can prevent the pressing cover from detaching from the panel support and the main locking component during the reset process.

[0012] Preferably, the front end of the latch head is provided with a latch bevel. When the panel assembly is placed on the latch bevel and pressed, the panel assembly and the latch bevel can slide relative to each other, causing the main latch component to retract until the latch head disengages from the underside of the panel assembly and compresses the elastic element. The elastic element's rebound can push the main latch component back to its original position. With this structure, simply placing the panel assembly on the latch bevel and pressing it is enough to push the main latch component past the panel assembly and ultimately reset the main latch component to lock the panel assembly.

[0013] Preferably, the panel support is provided with a panel groove, and at least one panel pop-out member is provided at the bottom of the panel groove. The panel pop-out member is elastic, and the panel assembly is loosely fitted within the panel groove. When the locking assembly locks the panel assembly, the panel pop-out member is compressed. When the panel assembly is unlocked, the panel pop-out member can spring back and push the panel assembly out of the panel groove. With this structure, the panel assembly is loosely fitted within the panel groove, making the surface of the pad part flat, convenient to use, and also providing a limiting effect on the panel assembly. As long as the panel assembly is unlocked, the panel pop-out member can eject the panel assembly from the panel groove, making it easy to remove the panel assembly.

[0014] Preferably, the bottom of the panel slot is provided with a pop-out mounting slot. The panel pop-out includes a second elastic member and a top plate. The lower end of the second elastic member is disposed in the pop-out mounting slot, and the top plate is connected to the upper end of the second elastic member and can enter the pop-out mounting slot along with the second elastic member. When the locking assembly locks the panel assembly, the panel pop-out is compressed in the pop-out mounting slot, and the top plate abuts against the lower side of the panel assembly. The second elastic member rebounds, causing the top plate to extend out of the pop-out mounting slot. This structure is simple and facilitates the installation of the panel pop-out. When the panel assembly is locked, the panel pop-out is compressed in the pop-out mounting slot, keeping the panel assembly flat. When the second elastic member rebounds, the top plate extends out of the pop-out mounting slot and pops the panel assembly out of the panel slot.

[0015] Preferably, the panel assembly includes a first panel, a second panel, and a panel frame. The first panel and the second panel are arranged back-to-back within the panel frame, which is used to fix the first panel and the second panel. The panel frame has mating structures on both its front and back sides that can engage with locking heads to lock the panel assembly, or mating structures on opposite sides of the panel frame that can engage with locking heads to lock the panel assembly. Regardless of whether the first panel or the second panel is facing upwards, there is a corresponding mating structure that can engage with the locking heads to lock the panel assembly. With this structure, the panel assembly is double-sided, allowing customers to customize two panels with different functions according to their needs and switch between them at any time. The two panels can be various types, such as whiteboards, cutting boards, heating pads, and soft pads, to meet the needs of more customers. Attached Figure Description

[0027] like Figure 2 As shown, the panel support 2 is provided with a panel groove 2-4, and the panel assembly 3 is fitted into the panel groove 2-4 with a clearance fit. Two pop-out mounting grooves 2-9 are provided at the bottom of the panel groove 2-4. A panel pop-out component 2-3 is provided within the pop-out mounting groove 2-9. The panel pop-out component 2-3 is elastic and includes a top piece 2-10 and a second elastic element, namely a second spring 9. The lower end of the second spring 9 is located within the pop-out mounting groove 2-9, and the top piece 2-10 is connected to the upper end of the second spring 9 and can enter the pop-out mounting groove 2-9 along with the second spring 9. Three limiting bosses 2-2 are provided on one side wall of the panel groove 2-4.

[0028] like Figure 4 and Figure 5 As shown, the locking assembly includes a locking main component 7, a pressing cover 6, and an elastic component, namely a first spring 8. The locking main component 7 has a locking head 7-4 at its front end, a spring groove 7-1 at its rear end, and a pressure post limiting groove 7-2 in its middle. The locking head 7-4 has a buckle bevel 7-5 at its front end, and a driven bevel 7-3 is provided in the pressure post limiting groove 7-2. The pressing cover 6 has sliding buckles 6-3 on both sides, with the two sliding buckles 6-3 located on the two outer sides of the locking main component 7. The lower end of each sliding buckle 6-3 has a buckle 6-4. The pressing cover 6 has a pressure post 6-1 on its lower side. The lower bottom surface of the pressure post 6-1 is set as a driving bevel 6-2. The lower end of the pressure post 6-1 is limited in the pressure post limiting groove 7-2, and the driving bevel 6-2 slides in contact with the driven bevel 7-3.

[0029] The panel support 2 is provided with a locking mounting groove 2-1, such as Figure 3As shown, the latch mounting groove 2-1 has an opening 2-5 on the side opposite to the panel assembly 3. A limiting seat 2-6 is provided on the groove wall of the latch mounting groove 2-1 opposite to the opening 2-5. The latch mounting groove 2-1 has a sliding groove 2-7 on the groove wall on both sides of the opening 2-5. A limiting crossbar 2-8 is provided in both sliding grooves 2-7.

[0030] The lower part of the main locking component 7 is inserted into the locking mounting groove 2-1. The spring groove 7-1 is opposite to the limiting seat 2-6. One end of the first spring 8 is limited on the limiting seat 2-6, and the other end is limited in the spring groove 7-1. That is, the first spring 8 is located between the main locking component 7 and the panel support 2. The locking head 7-4 can extend or retract through the opening 2-5. The two sliding buckles 6-3 are respectively limited in the sliding grooves 2-7 on the corresponding sides and slide up and down. The buckle head 6-4 is limited below the limiting crossbar 2-8. In this way, the pressing cover 6 is limited on the panel support 2 and can slide up and down.

[0031] like Figure 6 As shown, panel assembly 3 includes a first panel 3-3, a second panel 3-4, and a panel frame. The first panel 3-3 and the second panel 3-4 are arranged back-to-back within the panel frame. The panel frame includes a first frame 3-1 and a second frame 3-2, which are joined vertically and snap-fitted together to secure the first panel 3-3 and the second panel 3-4. The first panel 3-3 and the second panel 3-4 can be various types such as whiteboards, cutting boards, heating pads, and soft pads to meet the needs of more customers.

[0032] Three limiting slots 3-6 are provided on the upper and lower side walls of the panel assembly 3. The limiting slots 3-6 on any side wall can be matched with the limiting bosses 2-2. When the panel assembly 3 enters the panel groove 2-4, the limiting bosses 2-2 are inserted into the corresponding limiting slots 3-6 to limit the panel assembly 3.

[0033] Each of the left and right sides of the panel assembly 3 is provided with a locking slot 3-5. The locking slot 3-5 and the latch head 7-4 are respectively engaged. The latch head 7-4 is inserted into the corresponding locking slot 3-5 to lock the panel assembly 3.

[0034] Both the limiting slot 3-6 and the locking slot 3-5 are provided on the side walls of the first frame 3-1 and the second frame 3-2, and are jointly formed by the assembled first frame 3-1 and the second frame 3-2. Regardless of whether the first panel 3-3 is facing upward or the second panel 3-4 is facing upward, there is a corresponding locking slot 3-5 that cooperates with the limiting boss 2-2 to limit the panel assembly 3, and there is also a corresponding locking slot 3-5 that cooperates with the locking head 7-4 to lock the panel assembly 3.

[0035] When the panel assembly 3 is locked in the panel slot 2-4, the panel pop-out member 2-3 is compressed by the panel assembly 3. The panel pop-out member 2-3, including the second spring 9 and the top piece 2-10, is compressed in the pop-out member mounting slot 2-9, and the top piece 2-10 abuts against the lower side of the panel assembly 3.

[0036] To replace panel assembly 3 or to change the face of panel assembly 3, first press the pressing covers 6 on both sides, causing the pressing covers 6 to slide downwards along the slide groove 2-7. This drives the pressure column 6-1 to slide the driven inclined surface 7-3, causing the main locking component 7 to retract and compress the first spring 8. When the main locking component 7 retracts until the locking head 7-4 exits the locking slot 3-5, panel assembly 3 is unlocked. At this point, releasing the pressing covers 6 causes the first spring 8 to return the main locking component 7 to its original position. During the retraction of the main locking component 7, the driven inclined surface 7-3 can lift the pressure column 6-1, causing the pressing cover 6 to move upwards and reset. The limiting crossbar 2-8 limits the locking head 6-4, preventing the pressing cover 6 from detaching from the panel support 2 and the main locking component 7 during the retraction process.

[0037] When panel assembly 3 is unlocked, the second spring 9 rebounds and causes the top piece 2-10 to extend out of the pop-out mounting slot 2-9, and pops panel assembly 3 out of panel slot 2-4, at which point the old panel assembly 3 can be removed.

[0038] First, insert the lower part of the new panel assembly 3 into the upper part of the panel groove 2-4, so that the limiting protrusions 2-2 are inserted into the corresponding limiting slots 3-6 one by one; then, press the two sides of the upper part of the new panel assembly 3 onto the corresponding buckle slopes 7-5, so that the panel assembly 3 and the buckle slopes 7-5 can slide relative to each other, so that the main locking component 7 retracts until the locking head 7-4 disengages from the lower side of the panel assembly 3. During this process, the first spring 8 is compressed; when the upper part of the new panel assembly 3 is pressed down until the locking slots 3-5 are aligned with the locking head 7-4, the first spring 8 rebounds and pushes the main locking component 7 to reset, and the locking head 7-4 enters the locking slots 3-5, locking the panel assembly 3. After the panel assembly 3 is locked again, the panel pop-out component 2-3 is also compressed again into the pop-out component mounting slot 2-9.

[0039] In other embodiments, the panel support 2 may not have a panel groove 2-4. The panel assembly 3 is directly laid on the upper side of the panel support 2. The locking assembly and the limiting boss 2-2 are arranged front-to-back or left-to-right on the upper side of the panel support 2. The locking slot 3-5 is provided on the end faces of the first frame 3-1 and the second frame 3-2. Regardless of whether the first panel 3-3 or the second panel 3-4 is facing upwards, that is, regardless of whether the first frame 3-1 or the second frame 3-2 is facing upwards, there is a corresponding limiting slot 3-6 that can engage with the limiting boss 2-2 to limit the panel assembly 3, and there is a corresponding locking slot 3-5 that can engage with the locking buckle 2-1 to lock the panel assembly 3.

[0040] The posture corrector with a quick-change panel of this utility model can also be provided with an angle adjustment bracket below the panel support 2, which is used to support the rear side of the panel support 2 upward, so that the panel support 2 is tilted on the table and the angle between the panel support 2 and the table can be adjusted.

[0041] The above are merely specific embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Any modifications or equivalent substitutions to this utility model without departing from its spirit and scope should be covered within the protection scope of the claims of this utility model.
