Description

Technical Field

[0001] The utility model relates to the technical field of clamping brackets, in particular to a bracket clamping mechanism and a corrector comprising the bracket clamping mechanism. Background Art

[0002] As people's quality of life improves, the application scenarios of various product stands are becoming more and more extensive, and the product stands currently on the market include mobile phone stands, tablet stands, reading stands, and sitting posture correctors, etc. Regardless of the type of product stand, the main structure includes a support rod, and a clamping mechanism and a functional structure respectively arranged at the bottom and top of the support rod, among which the bottom clamping mechanism is mainly used to fix the entire stand on a desktop, bedside or other flat objects that can be clamped.

[0003] Traditional bracket clamping mechanisms are mostly in the form of spring clamps, but the opening angle of the bracket spring clamps in this form is limited, and they can only be clamped on thin flat objects, and have poor adaptability; and the clamping force is provided by the torsion torque of the torsion spring in the spring clamp, and this torsion torque cannot withstand large external impact forces, so the clamping on the flat object is not firm and is easy to loosen. Based on the defects of the traditional bracket clamping mechanism, the prior art proposes a clamping plate type clamping mechanism (such as the patent with publication number CN203836533U), which includes two parallel clamping plates, and also includes guide columns and guide sleeves respectively cooperating with the two clamping plates. The two clamping plates can be arbitrarily adjusted in distance between the two clamping plates by cooperating with the guide columns and guide sleeves, so that the clamping mechanism can adapt to and clamp flat objects of different thicknesses.

[0004] Although the clamping plate type clamping mechanism has strong adaptability, the existing clamping structure mainly uses a pressure locking member to press to force the two clamping plates to move toward each other. After the two clamping plates clamp the object on the corresponding plane, they still use a pressure locking member to lock it. Since the pressure locking member is separated from the clamping plate and is independently arranged above the clamping plate, if the pressure locking member is accidentally touched, it is easy to cause the clamping plate to loosen or unlock, and the locking is not firm.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0042] The bracket clamping mechanism of the utility model is applicable to the splint-type clamping mechanism in the prior art, and there is no limitation on the specific functional structure adopted on the upper part of the clamping mechanism. It can be a fixing device for a mobile phone or tablet, or a posture correction device (such as a sitting posture corrector), etc.

[0043] Example 1

[0044] like Figures 1 to 11 As shown, a bracket clamping mechanism includes an upper clamping plate 1 and a lower clamping plate 2, and also includes a guide column 3 vertically connected to one side of the lower clamping plate 2, and a guide sleeve 4 vertically connected to one side of the upper clamping plate 1, and the upper clamping plate 1 is slidably sleeved on the guide column 3 through the guide sleeve 4, and a plurality of tooth grooves 5 are vertically arranged on the guide column 3;

[0045] The locking assembly is also included, which is rotatably connected to the upper clamping plate 1. The locking assembly includes a first locking member 6 and a second locking member 7. A resilient member 8 is provided between the first locking member 6 and the second locking member 7.

[0046] The second locking member 7 is rotatably disposed on the upper clamping plate 1, the first locking member 6 is a free end, and the second locking member 7 is provided with a tooth portion 9 for cooperating with the tooth groove 5 at one end away from the first locking member 6;

[0047] The first locking member 6 is provided with a first locking mechanism 10 which cooperates with the upper clamping plate 1, and the upper clamping plate 1 is provided with a second locking mechanism 11 which matches with the first locking mechanism 10. When the first locking member 6 is pressed down on the upper clamping plate 1, the first locking mechanism 10 cooperates with the second locking mechanism 11, and under the action of the rebound member 8, the first locking member 6 can maintain a locked state with the upper clamping plate 1; pushing the first locking member 6 horizontally toward the second locking member 7 can release the cooperation between the first locking mechanism 10 and the second locking mechanism 11, thereby unlocking the first locking member 6 from the upper clamping plate 1.

[0048] like Figure 2 and Figure 3 As shown, the top of the upper clamping plate 1 of this embodiment is provided with an embedding groove 17 which cooperates with the locking assembly. The locking assembly is installed on the upper clamping plate 1 in an embedded manner, which not only has a beautiful structure, but is also not easily touched and fallen off by the outside world to affect the locking effect. It has good stability and strong practicality.

[0049] The end of the second locking member 7 close to the guide column 3 is hinged to the upper clamping plate 1, and a hinge pin hole 18 is provided on the second locking member 7, and a hinge groove 19 matching the hinge pin hole 18 is provided on the side wall of the embedding groove 17 on the upper clamping plate 1. During actual assembly, a pin is set in the hinge pin hole 18 of the second locking member 7 and matched with the hinge groove 19.

[0050] When this embodiment is actually used, the locking assembly is first unlocked, and the first locking member 6 is tilted. Then the upper clamping plate 1 and the lower clamping plate 2 are moved to an appropriate distance and clamped on the plane. Then the first locking member 6 is pressed downward. Since the tooth portion 9 on the second locking member 7 cooperates with the tooth groove 5, the upper clamping plate 1 and the lower clamping plate 2 can be forced to move toward each other during the pressing process to achieve clamping. After the first locking member 6 is pressed downward until it contacts the upper clamping plate 1, the first locking member 6 is continued to be pressed downward until the first locking member cooperates with the second locking member 7 to lock. At this time, the entire bracket clamping mechanism can be fixed on the plane.

[0051] In one embodiment of the present invention, the first locking mechanism 10 is a hook structure provided at the bottom of the first locking member 6, and the second locking mechanism 11 is a card interface provided on the upper clamping plate 1 and matching the hook structure. The width of the card interface is greater than the width of the hook to ensure that the first locking member 6 can work normally. Figures 6 to 11 shown.

[0052] In another solution of this embodiment, the first locking mechanism 10 can also be a card interface provided at the bottom of the first locking member 6, and the second locking mechanism 11 is a hook structure provided on the upper clamping plate 1 and matching the card interface. The hook in this solution faces one side of the second locking member 7 to ensure that it can hook the card interface of the first locking member 6, and the width of the card interface is greater than the width of the hook to ensure that the first locking member 6 can work normally.

[0053] (This method is not shown in the attached figure)

[0054] like Figures 1 to 11 As shown, in the present embodiment, a first limiting hook 12 is further provided inside the side wall of the first locking member 6, and a first limiting opening 13 matching with the first limiting hook 12 is opened on the side wall of the second locking member 7, and the length of the first limiting hook 12 (the length direction here refers to the direction from the first locking member 6 to the second locking member 7) is smaller than the length of the first limiting opening 13, so that the first limiting hook 12 slides left and right in the first limiting opening 13; the first limiting hook 12 is embedded in the first limiting opening 13, so that the first locking member 6 and the second locking member 7 are buckled.

[0055] In this embodiment, the first limit hook 12 is a protrusion provided on two sides of the first locking member 6, and the number of protrusions on each side is more than one, and the specific number can be selected according to actual conditions. The second locking member 7 is provided with a first limit opening 13 matching the first limit hook 12, and the width of the first limit opening 13 is greater than the width of the first limit hook 12, so as to ensure that the first locking member 6 and the second locking member 7 can move relative to each other.

[0056] like Figures 6 to 11As shown, in this embodiment, the first locking member 6 is also provided with a first spring mounting portion 20, and the second locking member 7 is provided with a second spring mounting portion 21; the resilient member 8 is a coil spring, one end of the coil spring cooperates with the first spring mounting portion 20, and the other end cooperates with the second spring mounting portion 21. Specifically, the first locking member 6 is not provided with a bottom plate, and a vertically downward auxiliary plate is provided at the top of the cavity of the first locking member 6, and baffles 22 are provided on both sides of the auxiliary plate to limit the coil spring, and the groove-shaped area formed by the auxiliary plate and the baffles 22 on both sides serves as the first spring mounting portion 20. The auxiliary plate extends downward and a first locking mechanism 10 that cooperates with the clamping plate is provided at the bottom of the auxiliary plate. A reinforcing rib is also provided between the auxiliary plate and the cavity wall of the first locking member 6 to reinforce the auxiliary plate and improve its strength. The second spring mounting portion 21 is a columnar structure provided on the second locking member 7, and the columnar structure is provided perpendicular to the auxiliary plate. When installing the coil spring, one end of the coil spring is sleeved on the columnar structure of the second locking member 7, and the other end is placed in the groove area formed by the auxiliary plate and the baffles 22 on both sides.

[0057] like Fig.11 As shown, in an application scenario of the present embodiment, the bracket clamping mechanism is applied in the corrector. Specifically, an anti-bending posture correcting device 16 is provided on the top of the guide sleeve 4. The anti-bending posture correcting device 16 includes a telescopic rod 161 sleeved on the outside of the guide sleeve, and a plurality of contact pads 162 disposed laterally on the upper end of the telescopic sleeve. The contact pads 162 are disposed on the side away from the clamping mechanism. When in use, the lower clamping plate 2 and the upper clamping plate 1 are clamped on the upper and lower sides of the desktop respectively, and the side with the contact pad 162 is close to the human body. When in use, the user's chest is pressed against the contact pad 162 to prevent bending and lowering the head.

[0058] Example 2

[0059] Compared with Example 1, the upper clamping plate 1, the lower clamping plate 2, the guide column 3 and the guide sleeve 4 of this embodiment are exactly the same (the above-mentioned mechanism will not be described in detail below), and the working principle is also the same. The only difference is that the partial structure of the locking component is different. The locking component in Example 2 is specifically as follows.

[0060] like Figure 1 , Figure 2 , Figure 3 , Figures 12 to 20 As shown, in this embodiment, the first locking member 6 is sleeved on the outer end of the second locking member 7, and a second limiting hook 14 is provided at the bottom of the second locking member 7. A second limiting opening 15 matching with the second limiting hook 14 is opened at the bottom of the first locking member 6, and the width of the second limiting hook 14 (the width direction here refers to the direction along the first locking member 6 pointing to the second locking member 7) is smaller than the width of the second limiting opening 15, so that the second limiting hook 14 slides left and right in the second limiting opening 15.

[0061] In this embodiment, the second limit hook 14 is a protrusion arranged at the bottom of the second locking member 7, and the number is one or more, and the specific number can be selected according to actual conditions. A second limit opening 15 matching the second limit hook 14 is opened on the bottom plate of the first locking member 6, and the width of the second limit opening 15 is greater than the width of the second limit hook 14, so as to ensure that the first locking member 6 and the second locking member 7 can move relative to each other.

[0062] like Figure 2 , Figure 3 , Figure 6 , Figures 18 to 20 As shown, in this embodiment, the first locking member 6 is further provided with a first spring mounting portion 20, and the second locking member 7 is provided with a second spring mounting portion 21; the resilient member 8 is a coil spring, one end of the coil spring cooperates with the first spring mounting portion 20, and the other end cooperates with the second spring mounting portion 21. Specifically, the first spring mounting portion 20 is a columnar structure provided on the first locking member 6, and the second spring mounting portion 21 is a columnar structure provided on the second locking member 7, and the axial extension lines of the two columnar structures coincide. When installing the coil spring, the two ends of the coil spring are respectively sleeved on the columnar structures of the first locking member 6 and the second locking member 7.

[0063] like Fig. 20 As shown, in an application scenario of the present embodiment, the bracket clamping mechanism is applied in the corrector. Specifically, an anti-bending posture correcting device 16 is provided on the top of the guide sleeve 4. The anti-bending posture correcting device 16 includes a telescopic rod 161 sleeved on the outside of the guide sleeve, and a plurality of contact pads 162 disposed laterally on the upper end of the telescopic sleeve.
