Technical Field

[0001] The utility model belongs to the technical field of leg muscle training equipment, in particular to a leg muscle training device. Background Art

[0002] There are many ways to train your legs, such as using a leg press machine. The leg press machine is mainly composed of a weight rack, weight blocks, pedals, and a backrest.

[0003] When using it, the trainee lies on his back on the backrest of the inverted leg press machine, bends his knees, and places his feet on the pedals of the inverted leg press machine. The pedals are equipped with weight racks and weight blocks. Then, the trainee pushes his feet diagonally upward, so that the feet push the pedals to move, and the pedals drive the weight blocks to move until the legs are straightened. Then, the trainee slowly retracts the movement, adjusts and starts again, so as to train the legs.

[0004] During this use, both legs are trained to exercise the quadriceps (front thigh muscles) and calf muscles; however, the leg press machine is suitable for moving both legs together; when we need to exercise the quadriceps and gluteal muscles, especially the posterior thigh muscles, we need to train with one leg, but the currently available leg press machines cannot be used for training in a single-leg alternating manner, which is inconvenient for exercising the trainee's quadriceps, gluteal muscles and thigh muscles. Utility Model Content

[0006] The leg muscle training device comprises a vertically arranged base plate, a support frame with a "door"-shaped structure is arranged on the front side of the base plate, and the support frame is obliquely installed on the front side wall of the base plate through a support rod; a backrest for a trainee to sit on is installed on the base plate below the support frame, a first limit block is horizontally fixed between the support frames, and a partition is fixed between the first limit block and the inner top of the support frame; the partition divides the interior of the support frame into two independent left and right sections; pedals for the trainee to perform leg-pushing training are arranged in both sections; sliding grooves for the pedals to slide up and down are provided corresponding to the partitions and the support frames, and the pedals are matched with the sliding grooves to slide up and down; and counterweight components for weighting the pedals are arranged on the pedals.

[0007] Furthermore, the counterweight assembly includes a vertically arranged counterweight rod, the lower end of which is fixed to the top of the pedal, and a plurality of counterweight blocks are mounted on the counterweight rod.

[0008] Furthermore, the pedals are each provided with a first through hole communicating with each other up and down, and a slide rod is passed through the first through hole and slidably cooperates with the first through hole up and down; the upper end of the slide rod is fixed to the inner top of the support frame, and the lower end thereof is fixed to the first limit block.

[0009] Furthermore, reinforcing ribs are installed on both the left and right sides of the pedal, and the reinforcing ribs and the slide grooves are in upward and downward sliding cooperation.

[0010] Furthermore, handles are installed on the bottom plates on the left and right sides of the backrest.

[0011] Furthermore, second limit blocks are fixed to the bottom of the left and right pedals, and second through holes communicating with each other on the left and right are opened on the second limit blocks, and the same connecting plate for pedaling is installed in the second through holes.

[0012] Furthermore, there are two second limit blocks at the bottom of the pedal, and the two second limit blocks are arranged left and right.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0019] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention. Example

[0020] A leg muscle training device described in this embodiment, such as Figure 1 and Figure 2 As shown, it includes a vertically arranged bottom plate 1, a support frame 5 in a "door"-shaped structure is arranged on the front side of the bottom plate 1, and the support frame 5 is obliquely installed on the front side wall of the bottom plate 1 through a support rod 14; Figure 2 In the orientation, when the support frame 5 is installed, it is in an inclined state with the left side higher and the right side lower. There are two support rods 14, one end of which is fixed to the top position of the support frame 5, and the other end is fixed to the left side wall of the bottom plate 1; the lower end of the support frame 5 is fixed to the left side wall of the bottom plate 1; so that the support frame 5 can be installed on the bottom plate 1 in an inclined state;

[0021] like Figure 1 and Figure 2 As shown, a backrest 13 for a trainee to sit on is installed on the bottom plate 1 below the support frame 5, as shown in FIG. Figure 2 In the middle position, the backrest 13 is also installed on the bottom plate 1 in an inclined manner, and is mainly composed of an upper and lower part, wherein the upper part is higher on the left and lower on the right, and the lower part is lower on the left and higher on the right; when in use, the trainee's buttocks sit on the upper part of the backrest 13, and his back leans against the lower part of the backrest 13;

[0022] like Figure 1 As shown, a first limit block 2 is horizontally fixed between the support frames 5. When the first limit block 2 is specifically installed, its left side wall is fixed to the left inner side wall of the support frame 5, and its right side wall is fixed to the right inner side wall of the support frame 5; the first limit block 2 is located at a lower position between the support frames 5;

[0023] like Figure 1As shown, a partition 6 is fixed between the first limit block 2 and the inner top of the support frame 5; the partition 6 divides the support frame 5 into two independent left and right sections; both sections are provided with pedals 3 for the trainee to perform leg-pushing training; corresponding partitions 6 and support frames 5 are provided with sliding grooves for the pedals 3 to slide up and down, and the pedals 3 are matched with the sliding grooves to slide up and down; when the partition 6 is installed, its top is fixed to the inner top of the support frame 5, and its bottom is fixed to the top of the first limit block 2; after the partition 6 is installed, the two sections in the support frame 5 are preferably the same size; when the sliding grooves are specifically provided, sliding grooves are provided on the left and right side walls of the support frame 5, and two The left and right sides of the pedal 3 are arranged in a left-right manner. The left side of the pedal 3 in the left section is in sliding cooperation with the slide groove on the left side of the support frame 5, and the right side is in sliding cooperation with the slide groove on the left side of the partition 6; the left side of the pedal 3 in the right section is in sliding cooperation with the slide groove on the right side of the partition 6, and the right side is in sliding cooperation with the slide groove on the right side of the support frame 5; therefore, the two pedals 3 can slide up and down independently in the corresponding sections; when in use, the soles of the trainees' feet are stepped on the pedals 3, and then when the legs drive the feet to move up and down, the pedals 3 can be driven to move up and down; in the process of moving up and down, because the pedals 3 are two separate ones, the two pedals 3 can be driven by one foot to move up and down in a cycle;

[0024] Further preferably, the slide groove is preferably a ladder-shaped groove, so that the pedal 3 can move more stably in the slide groove, allowing the trainer to train more safely;

[0025] like Figure 1 and Figure 2 As shown, the pedals 3 are vertically provided with counterweight rods 8, the lower ends of the counterweight rods 8 are fixed to the tops of the pedals 3, and a plurality of counterweight blocks 9 are mounted on the counterweight rods 8; this section of the scheme as a whole constitutes a counterweight assembly for weighting the pedals 3; when in use, according to the intensity of the trainee's training, the number of counterweight blocks 9 adapted to the trainee's physical fitness is selected and mounted on the counterweight rods 8; when the trainee pushes the pedals 3 to move upward, the counterweight blocks 9 are also pushed upward, thereby achieving the purpose of leg training; because the pedals 3 of this design are two, the trainee's legs can be trained alternately back and forth, thereby exercising the trainee's quadriceps, gluteal muscles and thigh muscles;

[0026] In the specific implementation process, the counterweight rod 8 in the counterweight assembly can be set to two left and right ones, and the counterweight blocks 9 are sleeved on the left and right counterweight rods 8, so that the counterweight can be increased, which is convenient for different personnel to use;

[0027] Further preferably, the pedal 3 is in an "L"-shaped structure, such as Figure 1 and Figure 2It can be seen that the horizontal section of the pedal 3 is used to place the trainee's feet, and the vertical section is located on the side close to the trainee, so the counterweight assembly is shielded as much as possible to avoid accidental injury to the trainee during the installation of the counterweight block 9;

[0028] like Figure 1 As shown, the pedals 3 are provided with first through holes communicating with each other from top to bottom, and the first through holes are penetrated with slide bars 7 and slide with each other up and down; the upper ends of the slide bars 7 are fixed to the inner top of the support frame 5, and the lower ends thereof are fixed to the first limit blocks 2; the slide bars 7 are located at the rear side of the counterweight assembly, and through the design of the slide bars 7, when the pedals 3 slide up and down, they will also slide on the slide bars 7, thereby enhancing the stability of the pedals 3 when sliding up and down, thereby improving the safety performance during use;

[0029] like Figure 1 and Figure 2 As shown, the left and right sides of the pedal 3 are both equipped with reinforcing ribs 4, and the reinforcing ribs 4 are slidably matched with the slide groove. When the reinforcing ribs 4 are specifically installed, one end of the reinforcing ribs 4 is fixed on the pedal 3, and the other end of the reinforcing ribs 4 is located in the slide groove. The design of the reinforcing ribs 4 can improve the stability of the pedal 3 when the edge slides, so that the pedal 3 can slide up and down more stably under the action of the counterweight assembly;

[0030] like Figure 1 and Figure 2 As shown, handles 12 are installed on the bottom plate 1 on both sides of the backrest 13. Through the design of the handles 12, when the trainer sits on and leans on the backrest 13 to push the pedal 3 to move, the trainer can hold the two handles 12 with both hands, so that the leg training process is more relaxed;

[0031] In the specific use process: first, the trainee sits on the backrest 13, then the left foot rests on the bottom of the left pedal 3, and the right foot rests on the bottom of the right pedal 3, and then according to the trainee's habits, for example, the left foot is used to push the left pedal 3 up and down, and then the right foot is used to push the right pedal 3 up and down; in this up and down movement process, because both legs can be used to push the pedal 3 back and forth to move up and down, single foot can be trained to achieve the purpose of training the quadriceps, gluteal muscles and thigh muscles; avoiding the problem in the prior art that both legs can only move up and down at the same time, but cannot train one leg. Example

[0032] This embodiment further illustrates the technology. Figure 1 , Figure 2 and Figure 3As shown, a second limiting block 10 is fixed to the bottom of the left and right pedals 3, and a second through hole communicating with each other on the left and right is opened on the second limiting block 10, and the same connecting plate 11 for pedaling is installed in the second through hole; after the connecting plate 11 is located in the second limiting block 10, the side wall of the connecting plate 11 fits together with the side wall of the second limiting block 10, and there is no gap for the connecting plate 11 to move too much; by arranging the second limiting block 10 at the bottom of the two pedals 3, the connecting plate 11 is located on the second limiting block 10; when in use, the left and right feet of the trainer both step on the connecting plate 11 to push it to move upward, thereby driving the two pedals 3 to move upward, exercising both legs at the same time, and achieving the purpose of training the quadriceps (front thigh muscles) and calf muscles; when it is not necessary to train both legs at the same time, the connecting plate 11 is taken out of the second limiting block 10, so as to perform single-leg training; therefore, the design of the connecting plate 11 facilitates double-leg training;

[0033] like Figure 1 As shown, there are two second limit blocks 10 at the bottom of the pedal 3, and the two second limit blocks 10 are arranged left and right. Through the two-piece design, not only can the connecting plate 11 be more stably limited at the bottom of the pedal 3, but the trainee's feet can also be stepped on the connecting plate 11 between the two second limit blocks 10, so as to facilitate the placement of the feet and make it more convenient to use.
