However, the grilling machines currently on the market do not have a limiting structure between the upper cover and the base, that is, after the upper cover is rotated and opened relative to the base, the upper cover cannot be limited and supported, which brings inconvenience to the user. The purpose of the present invention is to provide a toggle-type lifting rod hinge structure that can be used in a grilling machine to limit the upper cover and a grilling machine having the same. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a toggle-type lifting rod hinge structure and a grilling machine having the same. When the toggle-type lifting rod hinge structure is applied to the grilling machine, after the upper cover in the grilling machine is rotated and opened, the upper cover in the grilling machine can be limited and supported, thereby bringing convenience to the user in the process of using the grilling machine.

[0004] The toggle-type lifting rod hinge structure of the present invention includes a support, a rotating rod, a locking piece and an unlocking piece. A fixed shaft is provided on the support. The locking piece and the unlocking piece are sequentially mounted on the outside of the fixed shaft from left to right. A through hole is provided in the rotating rod. The locking piece is inserted into the through hole. A clamping platform is provided on the outer wall of the locking piece. An arc-shaped groove for the sliding of the clamping platform is provided on the inner wall of the through hole. A limiting structure for limiting the circumferential rotation of the locking piece relative to the support is provided between the locking piece and the support. An elastic piece is provided between the locking piece and the support. The elastic piece is used to exert a tendency on the locking piece to move toward one side of the rotating rod so that the clamping platform is engaged with the arc groove. The unlocking piece is used to drive the locking piece to move toward the side away from the rotating rod so that the clamping platform is separated from the arc groove.

[0005] The toggle-type lifting rod hinge structure of the present invention is characterized in that a cavity for accommodating the engaging member is provided on the side of the support facing the engaging member, and the limiting structure includes a limiting groove provided on the inner wall of the cavity, and the limiting groove is used for the insertion and sliding of the card platform; by adopting this structure, after the engaging member is installed in the cavity and the card platform is engaged with the limiting groove, the circumferential rotation of the engaging member relative to the support can be limited.

[0006] The toggle-type lifting rod hinge structure of the present invention, wherein the elastic member includes a spring, the spring is sleeved on the outside of the fixed shaft, and the two ends of the spring are respectively against the engaging member and the inner end of the cavity; by adopting the spring as the elastic member, the spring can always apply a force to the engaging member to move the engaging member toward the unlocking member, so that the engaging member can always be tightly pressed against the unlocking member.

[0007] The toggle-type lifting rod hinge structure of the present invention comprises a plurality of first steps uniformly distributed in the circumferential direction on the end surface of the locking member facing the unlocking member, and a first arc slope is formed between adjacent first steps; a second step with the same number as the first step is provided on one end of the unlocking member facing the locking member, and a second arc slope is formed between adjacent second steps, and the unlocking member is limited to rotate only toward one side relative to the locking member through the cooperation of the second step and the first step; after adopting this structure, the locking member can only rotate in one direction relative to the locking member, and when the unlocking member is rotated so that the end of the second arc slope closest to the locking member abuts against the end of the first arc slope closest to the unlocking member, the clamping platform on the outer wall of the locking member can disengage from the arc groove on the rotating rod, so that the rotating rod can rotate at a larger angle relative to the support. In addition, when the unlocking member is released and the rotating rod is continuously rotated, once the clamping platform on the locking member reaches the position of the arc groove on the rotating rod again, the spring can push the locking member so that the clamping platform on the locking member re-enters the arc groove.

[0008] The toggle-type lifting rod hinge structure of the present invention is characterized in that a handle is mounted on the outside of the fixed axis located on the side of the unlocking member away from the rotating rod, and a slot for partially inserting the unlocking member is provided on the side of the handle facing the unlocking member, and an arc-shaped sliding groove for inserting and sliding the card table is provided on the side wall of the slot; through the setting of the handle, the handle can play a role of supporting the unlocking member.

[0025] Example 1

[0026] like Figure 1-4 As shown, the toggle-type lifting rod hinge structure of the present invention includes a support 1, a rotating rod 2, a locking member 3 and an unlocking member 4. A fixed shaft is provided on the support 1, and the locking member 3 and the unlocking member 4 are sequentially mounted on the outside of the fixed shaft from left to right. A through hole 21 is provided in the rotating rod 2, and the locking member 3 is inserted into the through hole 21. A clamping platform 31 is provided on the outer wall of the locking member 3, and an arc-shaped groove 22 for the clamping platform 31 to slide is provided on the inner wall of the through hole 21. A limiting structure for limiting the circumferential rotation of the locking member 3 relative to the support 1 is provided between the locking member 3 and the support 1, and an elastic member is provided between the locking member 3 and the support 1. The elastic member is used to exert a tendency on the locking member 3 to move toward one side of the rotating rod 2 so that the clamping platform 31 is engaged with the arc-shaped groove 22, and the unlocking member 4 is used to drive the locking member 3 to move toward the side away from the rotating rod 2 so that the clamping platform 31 is disengaged from the arc-shaped groove 22.

[0027] A cavity 11 for accommodating the engaging member 3 is provided on the side of the support 1 facing the engaging member 3, and the limiting structure includes a limiting groove 12 provided on the inner wall of the cavity 11, and the limiting groove 12 is used for the insertion and sliding of the card platform 31; by adopting this structure, after the engaging member is installed in the cavity and the card platform and the limiting groove are engaged with each other, the circumferential rotation of the engaging member relative to the support can be limited.

[0028] The elastic member includes a spring 5, which is sleeved on the outside of the fixed shaft, and the two ends of the spring 5 are respectively against the engaging member 3 and the inner end of the cavity 11; by using the spring as the elastic member, the spring can always apply a force to the engaging member to move the engaging member toward the unlocking member, so that the engaging member can always be tightly pressed against the unlocking member.

[0029] A plurality of first steps 32 are uniformly distributed in the circumferential direction on the end surface of the engaging member 3 facing the unlocking member 4, and a first arc-shaped slope 33 is formed between adjacent first steps 32; a second step 41 of the unlocking member 4 facing the engaging member 3 is provided with the same number as the first step 32, and a second arc-shaped slope 42 is formed between adjacent second steps 41. The unlocking member 4 is limited to rotate only to one side relative to the engaging member 3 by the cooperation of the second step 41 and the first step 32; after adopting this structure, the locking member can only rotate relative to the engaging member 3. The part rotates in one direction, and when the unlocking part is rotated so that the end of the second arc-shaped slope closest to the engaging part abuts against the end of the first arc-shaped slope closest to the unlocking part, the platform on the outer wall of the engaging part can disengage from the arc-shaped groove on the rotating rod. In this way, the rotating rod can rotate at a larger angle relative to the support. In addition, when the unlocking part is released and the rotating rod is continuously rotated, once the platform on the engaging part reaches the position of the arc-shaped groove on the rotating rod again, the spring can push the engaging part so that the platform on the engaging part re-enters the arc-shaped groove.

[0030] A handle 6 is mounted on the outside of the fixed axis located on the side of the unlocking member 4 away from the rotating rod 2. A slot 61 for partially inserting the unlocking member 4 is provided on the side of the handle 6 facing the unlocking member 4. An arc-shaped slide groove 62 for inserting and sliding the card table 31 is provided on the side wall of the slot 61. Through the setting of the handle, the handle can play a role in supporting the unlocking member.

[0031] A rotating wheel 7 for driving the unlocking member 4 to rotate is mounted on the outside of the fixed axis located on the side of the handle 6 away from the unlocking member 4; a protrusion 43 is arranged on the outer wall of the unlocking member 4, an arc-shaped hole 63 is arranged on the handle 6 for the protrusion 43 to pass through and slide, and a slot 71 for engaging with the protrusion 43 is arranged on the rotating wheel 7; through the setting of the rotating wheel, when the rotating wheel is rotated, the rotating wheel can drive the unlocking member to rotate, and by setting an arc-shaped hole on the handle, the protrusion is slidably connected in the arc-shaped hole, so that the rotation angle of the unlocking member can be limited.

[0032] A lug 72 is provided on the end surface of the rotating wheel 7 away from the handle 6, and the lug 72 is used to abut against a finger to facilitate the rotation of the rotating wheel 7; through the setting of the lug, when the rotating wheel needs to be rotated, the lug can abut against the end of the finger, thereby facilitating the rotation of the rotating wheel.

[0033] The rotating rod 2 is provided with a bent edge 23 bent toward one side of the support 1, and the support 1 is provided with a step surface 13 on the side facing the rotating rod 2. The bent edge 23 is sleeved on the outside of the step surface 13 and is rotatably connected to the step surface 13; through the setting of the bent edge and the step surface, the bent edge can be sleeved on the step surface, so that when the rotating rod rotates relative to the support, the coaxiality of the rotating rod and the support can be ensured, and the rotation of the rotating rod can be made smoother.

[0034] The fixed shaft includes a bolt 8 and a support column 14 arranged on the bottom of the cavity 11, a threaded hole 15 is arranged in the support column 14, and the bolt 8 is threadedly connected to the threaded hole 15; by adopting this fixed shaft, the spring, the engaging part, the rotating rod, the unlocking part, the handle and the rotating wheel can be reliably installed on the support.

[0035] A grilling machine comprises an upper cover and a base, wherein the upper cover is rotatably connected to the base. The grilling machine further comprises the above-mentioned toggle-type lifting rod hinge structure, wherein a fixing portion 16 for fixing to the base in the grilling machine is provided on a support 1, and a connecting portion 24 for connecting to the upper cover in the grilling machine is provided on a rotating rod 2. The angle of the upper cover when opened relative to the base is controlled by the toggle-type lifting rod hinge structure.

[0036] Example 2

[0037] like Figure 5-6 As shown, the difference from Example 1 is that in this embodiment, the lug 72 is removed from the rotating wheel 7, and a plurality of circumferentially distributed recesses 73 are provided on the outer peripheral wall of the rotating wheel 7, and the recesses 73 are used for fingers to be inserted to facilitate the rotation of the rotating wheel 7; through the provision of the recesses, when the rotating wheel needs to be rotated, the fingers can be inserted into the recesses, so that the hand and the rotating wheel can achieve the purpose of anti-slip, thereby facilitating the rotation of the rotating wheel.

[0038] When the toggle-type lifting rod hinge structure is applied, the toggle-type lifting rod hinge structure can be applied to a grilling machine, for example, the fixed part on the support is fixed to the base in the grilling machine, and the connecting part on the rotating rod is connected to the upper cover in the grilling machine. In this way, when the rotating wheel is not rotated, the upper cover in the grilling machine can be opened by a certain angle relative to the base (for example, 105 degrees. In the present invention, through the cooperation of the clamping platform and the arc groove, when the rotating wheel is not rotated, the rotating rod can be rotated 105 degrees relative to the support, that is, after the upper cover in the grilling machine is opened 105 degrees relative to the base, the upper cover can be in a locked state due to the gravity of the upper cover), that is, it can play a role in limiting and locking the upper cover in the grilling machine; when the rotating wheel is rotated, the rotating wheel can drive the unlocking member to rotate, and the unlocking member can push the engaging member to make the clamping platform on the engaging member disengage from the arc groove on the rotating rod. At this time, the rotating rod can rotate a larger angle relative to the support, that is, the upper cover in the grilling machine can be opened by a larger angle relative to the base, for example, 180 degrees; the application scope of the present invention includes but is not limited to grilling machines.

[0039] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
