Description

Unlocking structure of soft light box chuck

[0001] The present application claims priority to the Chinese patent application No. 2024219713777, filed on August 15, 2024, and entitled "Unlocking structure of soft light box chuck", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of soft light boxes, in particular to an unlocking structure of a soft light box chuck. BACKGROUND

[0003] The Chinese patent document No. CN220913486U entitled "Chuck structure and soft light box" discloses a chuck structure, which is provided with a locking mechanism capable of individually locking each second rod and simultaneously releasing the locking state of all second rods. The structure includes a plurality of clamping blocks and elastic members arranged to push the corresponding clamping blocks to maintain the locking state. All clamping blocks are connected to a push plate, and the push plate is fixedly connected with a button. When the button is pressed close to the handle, the push plate moves, and the push plate simultaneously drives all clamping blocks to achieve simultaneous unlocking.

[0004] The above unlocking mechanism has a plurality of elastic members in the entire chuck structure in order to individually lock each clamping block to the second rod. The friction force between the push block and the push plate increases due to the elastic force generated by the deformation of the plurality of rods after locking, resulting in a large resistance when the finger presses the button to unlock in actual use, which makes the operation difficult and affects the use effect. SUMMARY

[0005] To solve the problems of the prior art, the present application provides an unlocking structure of a soft light box chuck, which is more labor-saving and smooth to operate.

[0006] The present application provides an unlocking structure of a soft light box chuck, which includes a push plate arranged in the chuck and configured to push the locking mechanism to unlock, and a button arranged on the chuck. The inner end of the button in the chuck is hinged to the chuck, the outer end of the button outside the chuck is a finger pressing part, the push plate is in abutment with the button and is pushed by the button to unlock the locking mechanism, and the distance from the abutment position of the push plate and the button to the hinge position of the button is less than the distance from the finger pressing part to the hinge position of the button.

[0007] Optionally, the chuck is further provided with a handle, and the finger pressing part of the button is turned in the direction close to the handle to push the push plate to move and unlock the locking mechanism.

[0008] Optionally, the moving direction of the push plate is consistent with the rotating direction of the finger pressing part when being unlocked.

[0009] Optionally, the push key is provided with a pushing surface, and the push plate is provided with a pushed surface, the pushed surface abuts against the pushing surface, and the abutting position of the pushed surface and the pushing surface is between the hinge position of the push key and the finger pressing part.

[0010] Optionally, the bottom surface of the push key is provided with a first protrusion, and the outer side of the push plate is provided with a second protrusion, the opposite sides of the first protrusion and the second protrusion are the pushing surface and the pushed surface respectively.

[0011] Optionally, the moving direction of the push plate is opposite to the rotating direction of the finger pressing part when being unlocked.

[0012] Optionally, the push key is provided with a pushing surface, and the push plate is provided with a pushed surface, the pushed surface abuts against the pushing surface, and the hinge position of the push key is between the abutting position of the pushed surface and the pushing surface and the finger pressing part.

[0013] Optionally, the bottom surface of the push key is provided with a first protrusion, and the inner side of the push plate is provided with a second protrusion, the opposite sides of the first protrusion and the second protrusion are the pushing surface and the pushed surface respectively.

[0014] Optionally, the finger pressing part is provided with an inner concave arc surface on the side surface for finger contact and pressing.

[0015] The beneficial effects of the present application: when operating the unlocking, the finger pressing part of the push key is pressed to push the push plate abutting against the push key to move, and the unlocking of the locking mechanism is realized. Since the distance from the abutting position of the push plate and the push key to the hinge position of the push key is smaller than the distance from the finger pressing part to the hinge position of the push key, the force required for the finger pressing part to unlock the push key is smaller than the force required for directly pressing the push plate to move, which helps to overcome the large unlocking resistance, and the unlocking operation is more labor-saving and smooth.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will further describe the embodiments of the present application in combination with the drawings.

[0024] The following description of the embodiments with reference to the drawings is not representative of all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0025] In the description of the present application, it should be understood that the terms "first", "second" and the like are used only for the purpose of description and should not be understood as indicating or implying relative importance. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, "a plurality of" means two or more, unless otherwise specified. "And / or", which describes the relationship between the associated objects, means that there can be three relationships, for example, A and / or B can mean that there are three cases of A alone, A and B together, and B alone. The character " / " generally represents a "or" relationship between the associated objects before and after it.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] Please refer to Figs. 1-4, the application provides an unlocking structure 10 of a soft light box chuck 100. The soft light box chuck 100 comprises a chuck 1, a locking mechanism 20 and the unlocking structure 10. The locking mechanism 20 is arranged in the chuck 1 and comprises a plurality of clamping blocks 4 and a plurality of springs 5 corresponding to the clamping blocks 4. Each clamping block 4 can lock a corresponding soft light box rod member. The unlocking structure 10 comprises a push plate 2 and a button 3. The push plate 2 is connected to the clamping blocks 4. When the button 3 is pressed to move the push plate 2, all the clamping blocks 4 can be simultaneously moved to be unlocked. Then the springs 5 push the clamping blocks 4 and the push plate 2 to be reset.

[0028] Because the elastic forces of the springs 5 are superimposed and the elastic force generated by the deformation of the rod member after being unfolded increases the moving friction of the clamping blocks 4 and the push plate 2, the resistance when the button 3 is pressed to be unlocked is greatly increased. The button 3 and the push plate 2 are in an integrated structure in the prior art. When the button 3 is directly pressed, the resistance is large and the unlocking is not smooth.

[0029] In view of the problems in the prior art, the button 3 and the push plate 2 are designed as a separated structure. The button 3 is hinged to the inner end of the chuck 1 and the outer end of the button 3 is a finger pressing part 32. The push plate 2 abuts against the button 3. The distance from the abutting position m of the push plate 2 to the hinge position p of the button 3 is less than the distance from the finger pressing part 32 to the hinge position p of the button 3, i.e. the force arm mp < np. When the finger pressing part 32 is pressed, the button 3 is rotated with a smaller force, which helps to overcome the resistance and more smoothly move the push plate 2 to unlock the clamping blocks 4.

[0030] In an embodiment, a handle 11 is arranged on the chuck 1 to facilitate pressing the button 3. When the finger pressing part 32 is rotated in the direction close to the handle 11, the button 3 is rotated to move the push plate 2 to unlock the locking mechanism 20.

[0031] In an embodiment, when being unlocked, the moving direction of the push plate 2 is consistent with the rotating direction of the finger pressing part 32 of the button 3. As shown in Fig. 2, when being unlocked, the finger pressing part 32 of the button 3 is rotated to the right and close to the handle 11, which moves the push plate 2 to the right. As shown in Fig. 2, the clamping part 41 of the clamping block 4 is arranged on the left side of the clamping block 4. At this time, the clamping block 4 needs to be moved to the right to be unlocked.

[0032] In the above embodiments, the first protrusion 31 is arranged on the bottom surface of the button 3, and the second protrusion 21 is arranged on the outer side of the push plate 2. Here, the center of the chuck 1 is regarded as the inside, and the outside is away from the center of the chuck 1. The opposite sides of the first protrusion 31 and the second protrusion 21 are respectively the pushing surface 311 and the pushed surface 211. Under the action of the spring 5, the push plate 2 is kept close to the button 3, so that the pushed surface 211 of the second protrusion 21 and the pushing surface 311 of the first protrusion 31 are kept in contact. When the button 3 rotates, the pushing force is transmitted through the pushing surface 311 and the pushed surface 211 to push the push plate 2. In this process, the pushing surface 311 and the pushed surface 211 will produce relative displacement. The abutment position m of the pushed surface 211 and the pushing surface 311 is between the finger pressing part 32 and the hinge position p of the button 3, so that the distance from the abutment position m to the hinge position p is smaller than the distance from the finger pressing part 32 to the hinge position p, thereby making the force arm mp < np, and ensuring the labor-saving of the unlocking operation.

[0033] In another embodiment, when unlocking, the moving direction of the push plate 2 is opposite to the rotating direction of the finger pressing part 32 of the button 3. As shown in FIG. 4, when unlocking, the finger pressing part 32 of the button 3 rotates to the right and moves to the left, thereby pushing the push plate 2. As shown in FIG. 4, the clamping part 41 arranged as a clamping rod on the clamping block 4 is located on the right side of the clamping block 4, and at this time, the clamping block 4 needs to move to the left to realize unlocking.

[0034] In this embodiment, the inner end of the button 3 extends to the inner side of the chuck 1 beyond the inner side surface of the push plate 2, the first protrusion 31 is arranged on the extending part of the button 3, and the second protrusion 21 is arranged on the inner side of the push plate 2. The opposite sides of the first protrusion 31 and the second protrusion 21 are respectively the pushing surface 311 and the pushed surface 211. Under the action of the spring 5, the push plate 2 is kept close to the button 3, so that the pushed surface 211 of the second protrusion 21 and the pushing surface 311 of the first protrusion 31 are kept in contact. The hinge position p of the button 3 is located between the abutment position m of the pushed surface 211 and the pushing surface 311 and the finger pressing part 32, so that when the finger pressing part 32 rotates to the right, the abutment position m moves to the left. In addition, the distance from the abutment position m to the hinge position p is smaller than the distance from the finger pressing part 32 to the hinge position p, thereby making the force arm mp < np, and ensuring the labor-saving of the unlocking operation.

[0035] In the above embodiments, the inner concave curved surface 321 is arranged on the side surface of the finger pressing part 32 arranged as the finger contact and pressing. When operating, the inner concave curved surface 321 can be fitted with the finger, so that the pressing is more comfortable.

[0036] The same or similar reference numerals in the drawings of the embodiments correspond to the same or similar components; in the description of the present application, it is understood that if the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right" and the like are based on the orientations or positional relationships shown in the drawings, they are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the terms describing the positional relationships in the drawings are only used for exemplary illustration, and cannot be understood as a limitation on the present patent, for those skilled in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0037] The above is only a preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
