Description

Technical Field

[0001] The utility model relates to the field of platform scales, in particular to a platform scale and a folding bracket thereof. Background Art

[0002] The electronic platform scale includes a weighing platform, a vertical pole and a weighing display, wherein the vertical pole is fixed on a fixed seat at the rear side of the weighing platform, and the weighing display is arranged at the upper end of the vertical pole. Since the vertical pole is roughly vertical to the weighing platform, it occupies a large space, making it inconvenient to transport or store. Therefore, a folding device is usually provided to enable the vertical pole to be folded relative to the weighing platform. The prior art, such as the Chinese utility model patent with the announcement number "CN201688908U", records a portable electronic platform scale, including a weighing platform, a vertical pole, and a meter head. The connection between the weighing platform and the vertical pole, and the connection between the vertical pole and the meter head are both equipped with a locking hinge switch. A handle for pulling out is provided on the side of the weighing platform. In its scheme, the locking hinge switch between the weighing platform and the vertical pole adopts a structure similar to an elastic latch. When the latch structure is locked, it can lock the weighing platform and the vertical pole. When it is pulled out, the column can be flipped relative to the weighing platform to achieve folding.

[0003] However, the above-mentioned existing folding structure is inconvenient to install, and there is a problem of insufficient stability in achieving the snap-fit ​​positioning only through the axially protruding portion of the pin shaft. Summary of the invention

[0004] In order to solve the above problems, the first purpose of the utility model is to provide a folding bracket, which has the advantages of simple structure, easy installation and convenient operation compared with the latch solution.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] A folding bracket comprises a base, and a flip cover which is rotatably arranged on the base via a rotating shaft; the flip cover can flip over relative to the base along the rotating shaft; it is characterized in that a locking rod assembly and a locking hook are respectively arranged on the upper end surface of the base and the lower end surface of the flip cover; the locking rod assembly comprises a rotatably arranged locking rod, and an elastic component which acts on the locking rod to drive the locking rod to circumferentially elastically compress; when the flip cover is in a covering state relative to the base, the hook portion of the locking hook is in the rotation path of the locking rod, and the elastic component acts on the locking rod to lock it with the hook portion of the locking hook.

[0007] The utility model adopts the above technical solution, which relates to a folding bracket, which includes a base and a flap connected by a rotating shaft, and the flap can be flipped relative to the base along the rotating shaft. During installation, the base is fixed to the scale platform, and the flap is fixed to the lower end of the column to achieve the flipping of the column relative to the scale platform. In this solution, the base and the flap are locked and moved by means of a locking rod assembly and a locking hook, wherein the locking rod assembly includes a locking rod and an elastic component, and the locking rod can move circumferentially and be compressed by the elastic component; in the locked state, the locking rod is clamped on the hook part of the locking hook under the elastic force of the elastic component. When unlocking, the user only needs to act on the locking rod to unlock.

[0008] Compared with the latch solution, this solution has the advantages of simple structure, easy installation and convenient operation.

[0009] In the embodiment, the flip cover and the base are constructed with an opening at the free end relative to the hinged end, and the toggle end of the lock rod faces the opening. In this way, the toggle end of the lock rod faces the front side, which is convenient for operation on the one hand, and on the other hand, there is no need to open holes on the side walls of the flip cover and the base, simplifying the process.

[0010] In a further embodiment, the toggle end of the lock bar extends to the outside of the opening of the flip cover and the base. In this way, the user can operate the lock bar to unlock the flip cover and the base outside without inserting a finger into the inside to toggle.

[0011] In a further embodiment, the lower end surface of the hook portion of the lock hook is constructed as a guiding inclined surface. When the lock hook descends, the guiding inclined surface acts on the lock rod and drives the lock rod to move in the circumferential direction in the opposite direction of the elastic compression. With this solution, the lock hook and the lock rod can be automatically engaged when the column is flipped to a vertical state through the action of the guiding inclined surface.

[0012] Preferably, the flip cover is provided with flip cover side panels on both ends, and the base is provided with base side panels on both sides, and the flip cover side panels are connected to the base side panels via a rotating shaft; the flip cover side panels are located outside the base side panels, and when the flip cover is in a closed state relative to the base, the upper end of the base side panels abuts against the lower end surface of the flip cover; or the base side panels are located outside the flip cover side panels, and when the flip cover is in a closed state relative to the base, the lower end of the flip cover side panels abuts against the base. In this solution, the flip cover and the base are locked together through the base side panels and the flip cover side panels to bear the force.

[0013] In a specific implementation scheme, the inner end of the locking rod is rotatably disposed on the upper end surface of the base or the lower end surface of the flip cover through a rotating column; the elastic component is a torsion spring, which is arranged on the rotating column and its deformed end is clamped on the locking rod.

[0014] Preferably, the flip cover is provided with a first through hole, and the flip cover is bent downward at least partially at the edge of the first through hole to form the locking hook as a whole; or the base is provided with a second through hole, and the base is bent upward at least partially at the edge of the second through hole to form the locking hook as a whole. In this solution, the locking hook is formed by integrally bending the flip cover or the base, which is convenient to process and has higher strength.

[0015] Preferably, a guide platform for guiding and limiting the circumferential rotation of the locking rod is constructed on the base or the flip cover; a guide slot is arranged in the guide platform, and the locking rod is movably arranged in the guide slot of the guide platform. Here, the guide slot in the guide platform can limit the circumferential movement path of the locking rod to ensure the stability of the structure.

A locking rod assembly 3 and a locking hook 4 are respectively arranged on the upper end surface of the base 1 and the lower end surface of the flip cover 2. The locking rod assembly 3 comprises a locking rod 31 rotatably arranged, and an elastic component 32 acting on the locking rod 31 to drive the locking rod 31 to elastically compress in the circumferential direction. When the flip cover 2 is in a closed state relative to the base 1, the hook portion 41 of the locking hook 4 is in the rotation path of the locking rod 31, and the elastic component 32 acts on the locking rod 31 to lock it with the hook portion 41 of the locking hook 4.

[0030] The folding bracket includes a base 1 and a flap 2 connected by a rotating shaft, and the flap 2 can be flipped relative to the base 1 along the rotating shaft. During installation, the base 1 is fixed to the weighing platform, and the flap 2 is fixed to the lower end of the column to achieve the flipping of the column relative to the weighing platform. In the scheme here, the base 1 and the flap 2 are locked and moved by means of a locking rod 31 assembly 3 and a locking hook 4, wherein the locking rod 31 assembly 3 includes a locking rod 31 and an elastic component 32, and the locking rod 31 can move circumferentially and be pressed by the elastic component 32. In the locked state, the locking rod 31 is clamped on the hook portion 41 of the locking hook 4 under the elastic force of the elastic component 32. When unlocking, the user only needs to act on the locking rod 31 to achieve unlocking.

[0031] Compared with the latch solution, this solution has the advantages of simple structure, easy installation and convenient operation.

[0032] like Figure 4 and 5 In the embodiment shown, the inner end of the locking rod 31 is rotatably arranged on the upper end surface of the base 1 or the lower end surface of the flip cover 2 through the rotating column 100. The elastic component 32 is a torsion spring, which is arranged on the rotating column 100 and its deformed end is clamped on the locking rod 31. The flip cover 2 and the base 1 are constructed with an opening 20 on the free end relative to the hinged end, and the toggle end of the locking rod 31 faces the opening 20. In this way, the toggle end of the locking rod 31 faces the front side, which is convenient for operation on the one hand, and on the other hand, there is no need to open holes on the side walls of the flip cover 2 and the base 1, simplifying the process. In a further embodiment, the toggle end of the locking rod 31 extends to the outside of the opening 20 of the flip cover 2 and the base 1. In this way, the user can operate the locking rod 31 to unlock from the outside of the flip cover 2 and the base 1 without inserting a finger into the inside to toggle.

[0033] In a further embodiment, the lower end surface of the hook portion 41 of the lock hook 4 is constructed as a guide slope 42. When the lock hook 4 moves downward, the guide slope 42 acts on the lock rod 31 and drives the lock rod 31 to move in the circumferential direction in the opposite direction of the elastic compression. With this solution, through the action of the guide slope 42, when the column is flipped to a vertical state, the lock hook 4 and the lock rod 31 can be automatically buckled.

The flip cover side panels 21 are located outside the base side panels 11, and when the flip cover 2 is in a closed state relative to the base 1, the upper end of the base side panels 11 abuts against the lower end surface of the flip cover 2. In another scheme, the base side panels 11 are located outside the flip cover side panels 21, and when the flip cover 2 is in a closed state relative to the base 1, the lower end of the flip cover side panels 21 abuts against the base 1. In this scheme, the flip cover 2 and the base 1 are locked to bear force through the base side panels 11 and the flip cover side panels 21.

In another alternative solution, the lock hook 4 is arranged on the base 1, specifically, a second through hole 12 is constructed on the base 1, and the base 1 is bent upward at least partially at the edge of the second through hole 12 to form the lock hook 4 as a whole. In this solution, the lock hook 4 is formed by integrally bending the flip cover 2 or the base 1, which is convenient to process and has higher strength.

[0036] In addition, Figure 3-5 As shown, a guide platform 13 for guiding and limiting the circumferential rotation of the locking rod 31 is constructed on the base 1 or the flip cover 2. A guide slot 131 is arranged in the guide platform 13, and the locking rod 31 is movably arranged in the guide slot 131 of the guide platform 13. Here, the guide slot 131 in the guide platform 13 can limit the circumferential movement path of the locking rod 31 to ensure the stability of the structure. In the specific implementation shown in the figure, a second through hole 12 is constructed on the base 1, and the base 1 is bent upward at least part of the edge of the second through hole 12 to form the guide platform 13 as a whole.
