Description

Technical Field

[0001] This utility model relates to the technical field of arm strength training devices, specifically to an arm strength trainer. Background Technology

[0002] Existing arm exercisers typically use springs to provide resistance to achieve muscle training effects; however, these arm exercisers have the drawback of not being able to adjust the resistance level, thus failing to meet users' different needs for resistance levels. Utility Model Content

[0003] To address the problem that the resistance of current arm exercisers cannot be adjusted, this invention provides an arm exerciser.

[0004] The technical solution of this utility model is as follows: On one hand, this utility model provides an arm strength exerciser, characterized by: a mounting base; two grip arms symmetrically hinged to the left and right sides of the mounting base; a bracket connected to the mounting base on the side facing the handles of the grip arms; a housing slidably connected to the bracket and disposed opposite to the mounting base; wherein the grip arms are connected to the housing via a linkage assembly, so that the rotation of the grip arms drives the housing to move closer to or away from the mounting base; an elastic damper connecting the mounting base and the housing respectively; a gas spring disposed side by side with the elastic damper, and including a fixed cylinder and a piston rod that cooperate with each other, the fixed cylinder being fixedly connected to the mounting base; wherein a switch is movably disposed on the housing corresponding to the piston rod, the switch having a connected state and a disconnected state with the piston rod.

[0005] Furthermore, when the switch and the piston rod are connected, the switch moving closer to the mounting base can push and compress the piston rod; and / or, when the switch and the piston rod are separated, the movement of the switch cannot compress the piston rod.

[0006] Furthermore, the switching element has a pushing portion that can move against the piston rod.

[0007] Furthermore, the switch is configured as a button rotatably connected to the housing, the button having a pressing portion exposed outside the housing and a pushing portion located inside the housing.

[0008] Furthermore, the switching element is located on the radial side of the piston rod, and the pushing part is movable at least in the radial direction.

[0009] Furthermore, a protrusion is fixedly provided on the outer side of the piston rod corresponding to the pushing part.

[0010] Furthermore, the protrusion is configured as a nut; the outer wall of the piston rod has threads for threaded connection with the nut.

[0011] Furthermore, multiple gas springs are provided; the switching element is configured to correspond one-to-one with the piston rod.

[0012] Furthermore, the number of gas springs is even, and all the gas springs are arranged symmetrically on the mounting base.

[0013] Furthermore, the outer casing covers the elastic damper and the gas spring.

[0014] The beneficial effects achieved by this utility model are as follows: The arm strength device of this utility model has an elastic damper that is normally open to continuously provide resistance; it also has a movable switch that allows the user to control the switch (i.e., the switch is in different positions) to connect or disconnect the outer shell from the gas spring. This allows the user to decide whether to add a gas spring to increase the resistance effect according to actual needs, so as to meet the user's different requirements for the resistance level.

[0022] For ease of description, spatial relative terms may be used in this text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in this text will be interpreted accordingly.

[0023] This application discloses an arm exerciser, including a mounting base 100; two grip arms 200 are symmetrically hinged to the left and right sides of the mounting base 100; a bracket 300 is connected to the side of the mounting base 100 facing the handle of the grip arms 200; a housing 400 is slidably connected to the bracket 300 and disposed opposite to the mounting base 100; wherein, the grip arms 200 are connected to the housing 400 through a connecting rod assembly 500, so that the rotation of the grip arms 200 drives the housing 400 to move closer to or away from the mounting base 100 on the bracket 300; the mounting base 100 and the housing 400 are connected by an elastic damper 600; a gas spring 700 is arranged side by side on one side of the elastic damper 600, the gas spring 700 includes a fixed cylinder 710 and a piston rod 720 that cooperate with each other, the fixed cylinder 710 is fixedly connected to the mounting base 100; wherein, a switch 410 is movably disposed on the housing 400 corresponding to the piston rod 720, and the switch 410 and the piston rod 720 have a connected state and a disconnected state.

[0024] In this embodiment, such as Figure 1As shown, when the arm exerciser is not in use, the two grip arms 200 are far apart, and the elastic damper 600 is not compressed. When it needs to be used, there are two situations: First, the switch 410 and the piston rod 720 are separated. Holding the two grip arms 200 and bringing them together, the grip arms 200 drive the housing 400 to move on the bracket 300 and gradually approach the mounting base 100 through the connecting rod assembly 500. At this time, the housing 400 overcomes the resistance of the elastic damper 600 and gradually compresses the elastic damper 600. Since the switch 410 and the piston rod 720 are separated, the gas spring 700 does not resist the mutual rotation and approach of the grip arms 200. When the force applied to the grip arms 200 is released, the elastic damper 600 resets, thereby driving the housing 400 away from the mounting base 100 and driving the grip arms 200 to reset to open. The first function is to facilitate the next use of the grip arm 200. The second function is to control the switch 410 to open, so that the switch 410 and the piston rod 720 are connected. When the two grip arms 200 are close together, the outer shell 400 not only needs to overcome the resistance of the elastic damper 600, but also needs to overcome the resistance of the gas spring 700 because the outer shell 400 is connected to the piston rod 720 through the switch 410. The rest of the process is similar to the above process and will not be described in detail. The switch 410 is movable, so that the user can control the switch 410 to open or close (that is, the switch 410 is in different positions) to make the outer shell 400 and the gas spring 700 connected or disconnected. Thus, the user can decide whether to add the gas spring 700 to increase the resistance effect according to the actual needs, so as to meet the different needs of the user for the resistance level.

[0025] Among them, such as Figure 1-4 As shown, the linkage assembly 500 may include two linkages. One end of the linkage is rotatably connected to the corresponding grip arm 200, and the other end is rotatably connected to the corresponding side wall of the housing 400, so that when the grip arm 200 is rotated, it can cooperate to push the housing 400 to slide on the bracket 300.

[0026] In an optional or preferred embodiment, multiple gas springs 700 are provided; the switch element 410 is configured to correspond one-to-one with the piston rod 720; one switch element 410 controls whether one gas spring 700 is connected to the housing 400, so that the arm strength device has a larger range of resistance adjustment while the adjustment accuracy is higher.

[0027] In an optional or preferred embodiment, the housing 400 covers the elastic damper 600 and the gas spring 700, which reduces the interference that may occur when the elastic damper 600 and the gas spring 700 are compressed and moved, and is also more aesthetically pleasing.

[0028] In an optional or preferred embodiment, the number of gas springs 700 is even, and all gas springs 700 are symmetrically arranged on the mounting base 100, thereby making the weight distribution of the arm strength trainer more balanced and more comfortable to use during exercise.

[0029] The gas spring 700 can be obtained commercially, so its specific structure will not be described in detail.

[0030] It should be understood that the elastic damper 600 can be an elastic telescopic rod, a spring, or the same gas spring structure as the gas spring 700.

[0031] In an optional or preferred embodiment, when the switch member 410 and the piston rod 720 are connected, the switch member 410 can push and compress the piston rod 720 when it is moved by the housing 400 to near the mounting base 100; when the switch member 410 and the piston rod 720 are separated, the movement of the switch member 410 cannot compress the piston rod 720.

[0032] In an optional or preferred embodiment, the switch member 410 has a pushing part 411 that can push the piston rod 720 to move. When the switch member 410 and the piston rod 720 are connected, the pushing part 411 abuts against the end face or protruding side of the piston rod 720, thereby pushing the piston rod 720 to move into the deep fixed cylinder 710. When the switch member 410 and the piston rod 720 are separated, the pushing part 411 moves away from the piston rod 720 and does not contact it. At this time, the movement of the housing 400 will not push the piston rod 720 to move. The connection or separation between the switch member 410 and the piston rod 720 is controlled by the pushing connection. The structural design is simple and compact, and the operation is stable and reliable.

[0033] In an optional or preferred embodiment, such as Figure 7 As shown, the switch 410 is configured as a button rotatably connected to the housing 400. The button has a pressing part 412 exposed outside the housing 400 and a pushing part 411 located inside the housing 400. When it is necessary to connect the switch 410 to the piston rod 720, the pressing part 412 is driven to rotate the switch 410 so that one end of the pushing part 411 approaches and abuts against the piston rod 720. Optionally, the switch 410 can be fixed by itself after rotating to a preset position, for example, by friction connection, elastic snap-fit ​​connection, etc.

[0034] In an optional or preferred embodiment, the switch 410 is located on the radial side of the piston rod 720, and the pushing part 411 is movable at least in the radial direction. By moving the pushing part 411 in the radial direction of the piston rod 720, the pushing part 411 and the piston rod 720 can have a coinciding pushing position in that radial direction. Thus, when the pushing part 411 is driven by the housing 400 to move axially along the piston rod 720, it can push against the piston rod 720 to perform compressive movement; when the pushing part 411 and the piston rod 720 do not have a coinciding pushing position in that radial direction, the axial movement of the housing 400 along the piston rod 720 cannot push against the piston rod 720 to perform compressive movement.

[0035] In an optional or preferred embodiment, a protrusion 721 is fixedly provided on the outer side of the piston rod 720 corresponding to the pushing part 411. The protrusion 721 and the pushing part 411 abut against each other in the radial direction of the piston rod 720, thereby controlling the connection or separation between the housing 400 and the piston rod 720.

[0036] In an optional or preferred embodiment, the protrusion 721 is configured as a nut; the outer wall of the piston rod 720 has threads for threaded connection with the nut, so as to facilitate the assembly and disassembly of the protrusion 721, and also to adjust its axial position on the piston rod 720.
