[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0034] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0035] Example 1

[0036] Reference Figure 1-3 This embodiment provides a spray can refill clamping mechanism.

[0037] The spray can refilling clamping mechanism includes a load-bearing component 100 and a clamping component 200.

[0038] Specifically, the support assembly 100 includes a back plate 101 and a circular base plate 102 fixed to the bottom of the back plate 101.

[0039] The clamping assembly 200 includes a secondary clamping member 201 located on the surface of the back plate 101. The secondary clamping member 201 includes a base plate 201a fixed to the surface of the back plate 101. Both sides of the interior of the base plate 201a are equipped with telescopic springs 201b. The other ends of the two telescopic springs 201b are connected to clamping pieces 201c. Both clamping pieces 201c extend through the exterior of the base plate 201a and are arranged opposite to each other. At the same time, the telescopic springs 201b can provide elastic support for the clamping pieces 201c to ensure that the clamping pieces 201c are always in the extended state. The front ends of the opposite side of the two clamping pieces 201c are rounded, and the bottom surfaces of the opposite side of the two clamping pieces 201c are wedge-shaped, which makes it easier to place the spray can.

[0040] When the spray can needs to be refilled, align the bottleneck of the top of the spray can with the two clamps 201c and push it inward. The rounded corners at the front of the clamps 201c allow the clamps 201c to compress the telescopic spring 201b and retract, thus allowing the spray can to smoothly enter between the two clamps 201c. The two clamps 201c hold the bottleneck of the spray can, while the bottom of the spray can is located on the circular base plate 102. At this time, the spray can is in a fixed state and can be refilled.

[0041] Example 2

[0042] Reference Figure 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that:

[0043] Furthermore, the clamping assembly 200 also includes a pusher 202 disposed on the outside of the secondary clamping member 201. The bottom of the pusher 202 is fixedly connected to a transmission member 203, and the lower outer side of the transmission member 203 is also covered by a cover 204. The cover 204 is fixed on the back plate 101, and the main clamping member 205 is also installed inside the cover 204.

[0044] The pusher 202 includes a main rod 202a that runs vertically through the substrate 201a, and a stop rod 202b is provided on the outer side of the top of the main rod 202a. The stop rod 202b is horizontally arranged and runs through the interior of the substrate 201a. A stop seat 202c is integrally provided at the front end of the stop rod 202b. The stop seat 202c is arranged on the same plane as the clamping piece 201c. Meanwhile, a partition plate 202d is fixedly connected to the lower end of the main rod 202a.

[0045] Two sets of transmission components 203 are symmetrically arranged about the partition plate 202d. Each set includes a secondary rod 203a fixed to the bottom surface of the partition plate 202d. The lower end of the secondary rod 203a has a transmission groove 203b on its outer surface, and a positioning block 203c is integrally formed on the outer surface of the middle section of the secondary rod 203a. A guide sleeve 203d is also fitted onto the positioning block 203c on the outer surface of the secondary rod 203a. The guide sleeve 203d is fixed to the back plate 101, and a positioning groove 203e is provided on the inner wall of the guide sleeve 203d to mate with the positioning block 203c. That is, the positioning block 203c and the positioning groove 203e... The cooperation between 3e can restrict and guide the movement of the auxiliary rod 203a, so that the auxiliary rod 203a can only move vertically in the axial direction, ensuring the normal cooperation between the auxiliary rod 203a and the main clamping part 205. The top of the guide sleeve 203d is also provided with a return spring 203f, which is located between the guide sleeve 203d and the partition plate 202d. The return spring 203f can cooperate with the partition plate through its own elastic force to maintain the initial state of the main rod 202a and the auxiliary rod 203a, so as to facilitate the smooth operation of the spray can clamping operation.

[0046] Furthermore, two separation grooves 204a are symmetrically arranged at the bottom of the inner wall of the cover 204, and positioning rings 204b are also symmetrically arranged at the bottom of the inner wall of the cover 204. At the same time, the bottom of the two sets of transmission components 203 are connected to the main clamping component 205. The main clamping component 205 includes a fixed tooth 205a rotatably connected to the top of the positioning ring 204b. The inner wall of the fixed tooth 205a is provided with a transmission column 205b, and the outer side of the fixed tooth 205a is engaged with a movable tooth 205c. The top surface of the movable tooth 205c is connected to a clamping plate 205d, which extends through to the outside of the cover 204 to clamp the lower part of the spray can. At the same time, the bottom surface of the movable tooth 205c is coaxially connected to a separation column 205e, and a clamping spring 205f is provided on the outer side of the separation column 205e. The surface of the clamping plate 205d is also provided with a compensation groove 205g, and the bottom of the clamping plate 205d is also provided with a compensation block 205h.

[0047] Preferably, the top of the main rod 202a and the end of the abutment rod 202b are both wedge-shaped, and the main rod 202a and the abutment rod 202b are mutually abutting. When the abutment seat 202c is squeezed, it can drive the abutment rod 202b to move backward. Under the squeezing fit of the wedge-shaped ends, the main rod 202a can move downward. This achieves the purpose of transmitting power to the auxiliary rod 203a through the cooperation of the main rod 202a and the abutment rod 202b when the abutment seat 202c moves backward, thereby realizing the control of the main clamping member 205. At the same time, the main rod 202a can always be at the highest point under the elastic force of the return spring 203f. Through the abutment between the main rod 202a and the abutment rod 202b, the abutment rod 202b can also be restricted by the main rod 202a and always remain in the extended state when not squeezed by the spray can.

[0048] The transmission column 205b can slide inside the transmission groove 203b. At the same time, the transmission groove 203b is inclined along the surface of the auxiliary rod 203a. So when the auxiliary rod 203a moves up and down, the transmission column 205b can be pushed by the transmission groove 203b to make the fixed tooth 205a rotate with the linear movement of the auxiliary rod 203a. Furthermore, under the meshing cooperation between the fixed tooth 205a and the movable tooth 205c, the movable tooth 205c can be driven to rotate synchronously, thereby causing the clamping plate 205d placed on it to rotate, thus realizing the clamping and releasing control of the spray can.

[0049] It should be noted that both the separating post 205e and the clamping spring 205f are located in the separating groove 204a, and the clamping spring 205f is located between the separating post 205e and the separating groove 204a. The clamping spring 205f can exert a spring force on the separating post 205e, thereby ensuring that the separating post 205e is always located at the end of the separating groove 204a close to the fixed tooth 205a, so as to achieve stable meshing between the movable tooth 205c and the fixed tooth 205a, and ensure that the fixed tooth 205a engages with the movable tooth 205c. During the normal transmission of 05c, when the clamping plate 205d clamps the spray can, the rotation of the movable tooth 205c is blocked. Thus, under the action of the tooth block of the fixed tooth 205a, the movable tooth 205c can be pushed to slide outward along the separation groove 204a under the drive of the separation column 205e, so that the movable tooth 205c separates from the fixed tooth 205a. This prevents the movable tooth 205c from interfering with the rotation of the fixed tooth 205a, while maintaining the normal clamping of the spray can by the clamping plate 205d.

[0050] The compensation block 205h and the compensation groove 205g are in a sliding fit. When the movable tooth 205c rotates, the compensation block 205h is located at one end of the axis of the movable tooth 205c on the compensation groove 205g. When the movable tooth 205c moves along the separation groove 204a and separates from the fixed tooth 205a, with the compensation groove 205g and the separation groove 204a on the same straight line and in opposite directions, the compensation block 205h and the compensation groove 205g can move relative to each other as the movable tooth 205c moves, thereby compensating for the displacement of the movable tooth 205c. This ensures that the movable tooth 205c can move on its own when the rotation point of the clamping plate 205d is fixed. At the same time, the compensation block 205h is square in shape, which ensures that even if there is relative displacement between the clamping plate 205d and the movable tooth 205c, the clamping plate 205d and the movable tooth 205c are still in a rotationally locked state.

[0051] During clamping, the bottom of the spray can contacts the base plate 102, and its bottleneck is flush with the auxiliary clamping member 201. The spray can is then pushed inward, and the bottleneck of the spray can squeezes the clamping plates 201c, causing the two clamping plates 201c to move outward, allowing the spray can to smoothly enter between the two clamping plates 201c for initial clamping. Simultaneously, as the bottleneck of the spray can enters, the abutment 202c is squeezed, and the abutment rod 202b generates a pushing force on the main rod 202a, causing the main rod 202a to move downward. Driven by the partition plate 202d, the auxiliary rods 203a on both sides move downward synchronously. At this time, with the cooperation of the transmission groove 203b and the transmission gear, the fixed gear 205a can be driven to rotate synchronously, and the movable gear 205c... Under the transmission, the two clamping plates 205d on both sides retract inward synchronously to clamp the spray can body. After clamping, since the clamping plates 205d are difficult to move further, the movable tooth 205c can move along the separation groove 204a under the push of the fixed tooth 205a. With the help of the transmission force of the fixed tooth 205a, it moves away from the fixed tooth 205a, thus avoiding further retraction of the clamping plates 205d. At the same time, it does not affect the subsequent rotation of the fixed tooth 205a. Through the cooperation between the pusher 202, the transmission 203 and the main clamping member 205, the clamping of the spray can can be completed when the spray can is placed, making the placement of the spray can more efficient and convenient, and reducing the difficulty of using the clamping component 200.

[0052] Example 3

[0053] Reference Figure 1-7 This is the third embodiment of the present invention, which is based on the previous embodiment and differs from the previous embodiment in that:

[0054] Each set of main clamping components 205 is provided with a positioning component 206 on the outside, and each positioning component 206 is also provided with an unlocking component 207 on the outside.

[0055] Specifically, a positioning platform 204c is symmetrically fixed to the top of the inner wall of the cover 204. The positioning component 206 includes a rotating platform 206a fixed to the surface of the clamping plate 205d. The top of the rotating platform 206a is fitted with the positioning platform 204c, and the rotating platform 206a and the movable tooth 205c are coaxially arranged. A retaining strip 206b is also provided inside the rotating platform 206a, and the retaining strip 206b extends to the outside of the rotating platform 206a. The outside of the rotating platform 206a is also fitted with a... A positioning ratchet 206c is provided, which is fixed to the top of the inner wall of the cover 204. Meanwhile, the locking strip 206b is made of soft material and can be slightly deformed. When the locking strip 206b rotates with the rotating table 206a, it can sweep along the direction of the locking teeth inside the positioning ratchet 206c and engage with the positioning ratchet 206c when it stops, thereby positioning the clamping plate 205d and preventing the inner clamping plate 205d from clamping the spray can and then rotating outward to open again.

[0056] The unlocking component 207 includes a movable ring 207a coaxially embedded inside the rotating platform 206a. The movable ring 207a has a notch 207b on its outer side. The retaining strip 206b on the outer wall of the rotating platform 206a extends outward through the notch 207b. At the same time, a torsion spring 207c is provided between the movable ring 207a and the rotating platform 206a. The torsion spring 207c is initially in an untightened state, which can ensure that the relative position between the movable ring 207a and the rotating platform 206a remains unchanged. Meanwhile, a pull rope 207d is fixed around the movable ring 207a. The pull rope 207d passes through the cover 204 and extends into the clamping plate 205d. One end of the pull rope 207d inside the clamping plate 205d is fixed to the lifting block 207f embedded therein. That is, one end of the pull rope 207d is fixed to the movable ring 207a, and the other end is fixed to the lifting block 207f.

[0057] Furthermore, a guide post 207e is provided on the outer side of the pull rope 207d, and the guide post 207e is fixed to the surface of the clamping plate 205d. The guide post 207e can guide the pull rope 207d, so that when the pull rope 207d is pulled, it can smoothly drive the movable ring 207a to rotate. When the movable ring 207a rotates, the outer notch 207b can squeeze the locking strip 206b, causing the locking strip 206b to retract. This releases the locking strip 206b from the positioning ratchet 206c, and the clamping plate 205d can rotate freely to release the clamping of the spray can.

[0058] During the clamping process, when the clamping plate 205d rotates with the movable tooth 205c to clamp the spray can, the rotating table 206a rotates synchronously inside the positioning ratchet 206c. After the clamping plate 205d completes clamping, the rotating table 206a remains stationary. The clamping angle is fixed by the engagement of the locking strip 206b and the positioning ratchet 206c, achieving stable clamping of the spray can and preventing it from loosening. When it is necessary to remove the spray can, the spray can can be lifted upwards first. The wedge-shaped setting of the clamping piece 201c and the contact surface of the spray can neck allows the two clamping pieces 201c to be further... The secondary outward movement does not affect the upward lifting of the spray can. At the same time, the lifting block 207f is supported by a material with high friction, such as rubber, and it is in close contact with the surface of the spray can. Thus, when the spray can moves upward, the lifting block 207f can be driven to move upward synchronously through friction. Then, under the pull of the pull rope 207d, the movable ring 207a rotates, the locking strip 206b retracts, and the engagement between the rotating table 206a and the positioning ratchet 206c is released. As a result, the clamp 205d can rotate freely, and the spray can can be taken out, making the removal of the spray can more convenient and efficient.
