Description

Technical Field

[0001] The utility model relates to the technical field of recording devices, in particular to an unlocking mechanism and an information classification recording device thereof. Background Art

[0002] Procurement refers to a series of behaviors and activities in which an individual or enterprise obtains products or services from the supply market as resources needed by the individual or enterprise under certain conditions in order to meet personal needs or ensure the normal development of the enterprise's production and business activities.

[0003] In the entire procurement process, in order to reduce the possibility of errors in the recording order when procurement personnel record procurement information, it is necessary to change the order of the placement books used to place information in the information classification recorder. However, the existing information classification recorder that can change the position of the placement books usually adopts a loose-leaf structure, that is, when the position of the placement book needs to be changed, the ring body needs to be bent to remove the placement book and change the position. However, when the placement book is changed by this method, the placement book located above the placement book to be moved can be moved before the placement book to be moved can be removed, which is inconvenient to replace. Once the ring body is opened, the fixed state of the placement book fixed by the ring body together with the placement book to be changed is also released. There is a risk that the placement books other than the placement book to be moved will accidentally fall off the ring body, which can easily cause confusion in the order of the placement books.

[0004] In addition, the entire placement book is usually placed by hanging it with a hook. Although it is simple, it is easy to touch it when passing by or taking down other placement books, causing the placement book to be knocked off and fall to the ground, which can easily cause the ring to be opened and the order of the placement books to be disrupted.

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one 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 term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1 to Figure 3 , which is the first embodiment of the utility model, and this embodiment provides a fixing mechanism, which includes a limiting assembly 100. The limiting assembly 100 can be used to fix the shell of the tire pressure sensor that needs to be welded, and prevent the shell from being displaced during subsequent welding and fixing.

[0033] Specifically, the fixing assembly 100 includes a fixing plate 101, a fixing shell 102 disposed on the end surface of the fixing plate 101, a moving column 103 disposed inside the fixing shell 102, a sleeve 104 disposed on the outer wall of the moving column 103, and a push column 105 disposed at the end of the fixing shell 102.

[0034] Among them, the fixed plate 101 is fixed inside the placement shell 201a, the fixed shell 102 is installed on both sides of the fixed plate 101, and a moving column 103 is provided inside each of the fixed shells 102 on both sides. The sleeve 104 is sleeved on the outside of the moving column 103, and the sleeve 104 and the moving column 103 both move inside the fixed shell 102. The push column 105 penetrates the fixed shells 102 fixed on both sides of the fixed plate 101, and moves inside the two fixed shells 102. At the same time, the push column 105 passes through the bottom of the moving column 103.

[0035] In summary, when in use, the push column 105 passes through the bottom of the two fixed shells 102, and the fixed shells 102 are fixed on the surface of the fixed plate 101. When it is necessary to remove the placement book 202, by pulling the push column 1025 inside the fixed shell 102 below the corresponding placement book 202, any side movement of the push column 105 will cause the moving column 103 and the sleeve 104 inside the fixed shells 102 on both sides to move downward. When the moving column 103 pulls the sleeve 104 to move downward toward the inside of the fixed shell 102, the connecting rod 104b on the outer wall of the sleeve 104 moves inward and retracts from the placement book 202, losing the fixing effect on the placement book 202. At this time, the placement book 202 can be taken out, and other placement books 202 are not affected.

[0036] Example 2

[0037] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0038] Specifically, a buckle 101a is provided on the end surface of the fixing plate 101, a limit shell 101b is movably provided on the inner wall of the buckle 101a, a receiving groove 102a is provided on the inner wall of the fixing shell 102, and a hinge rod 102b is provided on the inner wall of the receiving groove 102a.

[0039] Among them, the buckle 101a is fixed on the upper surface of the fixed plate 101, and two buckles 101a are provided, which are sleeved on the outside of the limiting shell 101b to fix the limiting shell 101b at the center of the fixed plate 101. The fixed shell 102 is fixed on both sides of the fixed plate 101. A receiving groove 102a is opened in the middle position of each fixed shell 102, and a moving column 103, a sleeve 104 and other components are placed in the receiving groove 102a. The hinge rod 102b is fixed on both sides of the inner wall of the receiving groove 102a.

[0040] Preferably, a movable groove 102c is provided at the bottom of the fixed shell 102, a hinge block 102d is provided on the outer wall of the fixed shell 102, a movable block 102e is hinged at the end of the hinge block 102d, a through groove 102e-1 is provided on the end face of the movable block 102e, and a moving rod 102f is provided at the end of the movable block 102e.

[0041] Among them, the movable groove 102c is at the bottom of the fixed shell 102, below the accommodating groove 102a, and has two sections, a vertical groove and a horizontal groove. The two grooves are connected. The vertical groove allows the moving column 103 to move up and down at the bottom of the fixed shell 102, and the push column 105 moves in the horizontal groove.

[0042] The hinge block 102d is fixed on the outside of the fixed shell 102, and the top of the hinge block 102d and the movable block 102e are hinged. The through groove 102e-1 is opened in the middle of the movable block 102e, and the inside of the movable block 102e is hollowed out and the surrounding surfaces are penetrated. The bottom position of the movable block 102e is connected with a moving rod 102f. By moving the moving rod 102f, the movable block 102e can be driven to rotate on the outside of the fixed shell 102 with the hinged part as the axis.

[0043] A cylinder 103a is disposed at the end of the motion column 103, a protrusion 103b is provided on the inner wall of the cylinder 103a, and a first elastic member 103c is sleeved on the outer wall of the motion column 103.

[0044] The cylinder 103a at the bottom of the moving column 103 moves up and down in the vertical groove of the movable groove 102c at the bottom of the fixed shell 102, the protrusion 103b penetrates the cylinder 103a, and the two sides of the protrusion 103b present a downward slope. The first elastic member 103c is sleeved on the outside of the moving column 103 and inside the accommodating groove 102a.

[0045] A connecting block 104a is provided on the outer wall of the sleeve 104, a connecting rod 104b is hinged on the outer wall of the connecting block 104a, a moving groove 104c is provided on the outer wall of the connecting rod 104b, and a pressing rod 104d is provided on the end of the connecting rod 104b.

[0046] The sleeve 104 is sleeved on the outside of the moving column 103 and also on the outside of the first elastic member 103c. The inner wall of the sleeve 104 has a frustum that is stuck above the first elastic member 103c. When the sleeve 104 moves downward, it squeezes the first elastic member 103c, causing it to be compressed and deformed.

[0047] A motion groove 104c is formed through the surface of the connecting rod 104b, and the top end of the hinged rod 102b arranged on the inner wall of the accommodating groove 102a extends to the inner wall of the motion groove 104c and slides inside. The pressure rod 104d at the top of the connecting rod 104b is initially above the fixed shell 102. When the sleeve 104 is driven to move by the moving column 103, the sleeve 104 moves downward, driving the connecting rod 104b downward. When the motion groove 104c on the surface of the connecting rod 104b moves downward, it is affected by the hinged rod 102b inside the accommodating groove 102a, and the connecting rods 104b on both sides will be retracted inward and retracted into the interior of the accommodating groove 102a from the top of the fixed shell 102.

[0048] A notch 105a is provided on the outer wall of the push column 105, a connecting plate 105b is provided on the end of the push column 105, the end of the connecting plate 105b extends into the through groove 102e-1, a sliding column 105c is provided on the outer wall of the connecting plate 105b, the end of the sliding column 105c extends to the inner wall of the through groove 102e-1 and slidably cooperates therewith.

[0049] The shape of the notch 105a matches the shape of the protrusion 103b at the bottom of the cylinder 103a. The notch 105a will move leftward or rightward by squeezing the oblique edges on both sides of the protrusion 103b to make the cylinder 103a move downward at the bottom of the fixed shell 102, thereby driving the sleeve 104 outside the moving column 103 downward, and making the connecting rods 104b on both sides move inward, and the pressure rod 104d at the top of the connecting rod 104b moves inward, losing the fixing effect on the upper surface of the fixed shell 102 for placing the book 202.

[0050] The connecting plate 105b is located at both ends of the push column 105 and extends to the outside of the fixed shell 102. The connecting plate 105b extends into the movable block 102e outside the fixed shell 102 and can be telescopically movable in the movable block 102e. The sliding column 105c on the surface of the connecting plate 105b extends from the through groove 102e-1 on the surface of the movable block 102e and slides inside. By pulling the moving rod 102f at the bottom of the movable block 102e on either side, the movable block 102e can be driven to move in the fixed shell 102. 02 rotates outside, because the push column 105 slides at the bottom of the fixed shell 102, it cannot move upward with the flipping of the movable block 102e, and can only slide left and right. Therefore, when the moving rod 102f is pulled, the push column 105 can be moved inside the fixed shell 102, thereby driving the cylinder 103a to move downward at the bottom of the fixed shell 102, driving the upper moving column 103 to push the sleeve 104 downward, driving the connecting rod 104b downward, and making the pressure rod 104d retract inward.

[0051] Preferably, a circular ring 105 d is sleeved on the outer wall of the push column 105 , and the circular ring 105 d is slidably matched with the limiting shell 101 b . A second elastic member 105 e is provided on the outer wall of the circular ring 105 d , and the second elastic member 105 e is sleeved on the outer wall of the push column 105 .

[0052] Among them, the circular ring 105d is fixed in the middle position of the push column 105, and the circular ring 105d is inside the limiting shell 101b. A second elastic member 105e is provided on the left and right sides of the circular ring 105d respectively. The other ends of the two second elastic members 105e are against the inner wall of the limiting shell 101b, and the circular ring 105e is pushed to the middle position of the limiting shell 101b by the second elastic member 105e. At this time, the notches 105a on both sides of the push column 105 are attached to the protrusions 103b at the bottom of the cylinder 103a. At this time, the sleeve 104 is pushed by the first elastic member 103c and is located in the upper position of the accommodating groove 102a. The side connecting rods 104b are opened to both sides, and the pressure rod 104d is pressed on the top of the placement book 202 to fix the placement book 202.

[0053] When the moving rod 102f is pulled, the push column 105 is driven to move. At this time, the ring 105d moves inside the limiting shell 101b and moves toward the moving rod 102f. At this time, the second elastic member 105e on this side is squeezed and deformed by the ring 105d. When the push column 105 moves, the moving column 103 and the sleeve 104 inside the fixed shell 102 move downward. When the moving rod 102f is no longer pulled, the second elastic member 105e that has been squeezed and deformed recovers its deformation and returns to the middle position of the limiting shell 101b, driving the push column 105 to reset.

[0054] In summary, when in use, the moving rod 102f outside the fixed shell 102 on either side is pulled to make the moving rod 102f flip outside the fixed shell 102. At this time, the connecting plate 105b at the end of the push column 105 is affected by the movement of the movable block 102e, and the push column 105 moves toward the pulled side. When the push column 105 moves, the oblique edges of the notches 105a on both sides of the push column 105 touch the oblique edges of the protrusions 103b inside the cylinder 103a, squeezing the oblique edges of the protrusions 103b, so that the cylinder 103a is fixed. When the bottom of the fixed shell 102 moves downward and the cylinder 103a moves downward, the sleeve 104 is pulled downward together. During the downward movement of the connecting rods 104b on both sides of the sleeve 104, the moving grooves 104c on the surface are affected by the hinged rods 102b on the surface of the accommodating groove 102a and move closer to the inside during the downward movement. At this time, the pressure rod 104d on the top of the connecting rod 104b moves inward and leaves the surface of the placement book 202, losing the fixation of the placement book 202, and the placement book 202 can be taken out at this time.

[0055] After that, the moving rod 102f is released, and the ring 105d in the middle of the push column 105 is pushed back to the middle position of the limiting shell 101b by the deformed second elastic member 105e. At this time, the push column 105 also returns to its initial state, and the recesses 105a on both sides of the push column 105 lose the squeezing of the oblique edges of the protrusions 103b. At this time, the first elastic member 103c recovers its deformation, driving the moving column 103 and the sleeve 104 to reset, and the connecting rod 104b and the pressure rod 104d on both sides of the sleeve 104 return to their original positions.

[0056] Example 3

[0057] Reference Figure 1 and Figure 5 , which is the third embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0058] Specifically, the installation component 200 includes a mounting shell 201 disposed on the outer wall of the fixing component 100 , a placement book 202 disposed on the outer wall of the installation shell 201 , and a placement plate 203 disposed on the outer wall of the installation shell 201 .

[0059] The placement book 202 is fixed to the surface of the installation shell 201 through the fixing assembly 100 , and the installation shell 201 is fixed to the outer surface of the placement plate 203 .

[0060] Preferably, a placement shell 201a is provided on the inner wall of the installation shell 201, a mounting plate 201b is provided at the end of the installation shell 201, a fixing hole 201c is provided on the end surface of the installation plate 201b, and an opening 202a is provided on the end surface of the placement book 202.

[0061] Among them, the placement shell 201a array has multiple fixed on the inner wall of the installation shell 201, each placement shell 201a fixes a placement book 202, the fixing plate 101 is fixed inside the placement shell 201a, and the placement book 202 is fixed by the fixing shell 102 on the surface of the fixing plate 101.

[0062] Openings 202a are provided on both sides of the placement book 202, and the position of each opening 202a is opposite to the position of the internal accommodating groove 102a of the fixed shell 102. The placement book 202 is fixed to the outside of the placement shell 201a by pressing the outer side of the opening 202a through the pressing rod 104d extending from the accommodating groove 102a.

[0063] Preferably, a fixing opening 203a is provided on the end surface of the placement plate 203, a locking groove 203b is provided on the inner wall of the fixing opening 203a, a locking column 203c is provided inside the fixing opening 203a, a protrusion 203d is provided on the end of the locking column 203c, and a third elastic member 203e is sleeved on the outer wall of the locking column 203c.

[0064] The fixing hole 201c on the surface of the mounting plate 201b is located opposite to the fixing opening 203a on the surface of the placing plate 203. The locking column 203c extends into the fixing opening 203a after passing through the fixing hole 201c. The protrusion 203d at the end of the locking column 203c slides along the locking groove 203b on the inner wall of the fixing opening 203a. During this process, the third elastic member 203e outside the locking column 203c is squeezed and deformed. When the protrusion 203d enters the bottom of the locking groove 203b and is locked, the third elastic member 203e is deformed. The elastic force of the elastic member 203e will cause the locking column 203c to extend outward, clamping the protrusion 203d in the fixing groove at the bottom of the locking groove 203b. At this time, the entire installation shell 201 is fixed to the outside of the placement plate 203. When the installation shell 201 needs to be removed, first disengage the protrusion 203d at the front end of the locking column 203c from the fixing groove at the bottom of the locking groove 203b, and then take the locking column 203c out of the fixing port 203a. During this process, even if it touches other placement books 202, it will not fall off the placement plate 203.
