Technical Field
[0001] The utility model belongs to the field of fitness equipment, and specifically relates to a dumbbell-barbell switching structure and a barbell using the structure. Background Art
[0002] Dumbbells and barbells are similar fitness equipment used for limb strength training. In the prior art, dumbbells include handles and gravity blocks, and barbells include gravity plates and a main rod body. Both adjust the training weight by increasing or decreasing the gravity blocks / gravity plates.
[0003] Since home fitness equipment needs to consider factors such as size and ease of storage, dumbbells and barbells, as commonly used home fitness equipment, are independent of each other, and gravity blocks and gravity plates are not interchangeable. In order to facilitate the adjustment of training weights, multiple gravity blocks / gravity plates are required, which take up a lot of space and are not easy to store. Utility Model Content
[0004] The purpose of the utility model is to provide a dumbbell-barbell transition structure and a barbell using the structure in order to solve the above problems.
[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:
[0006] A dumbbell-barbell transition structure comprises a connecting part and an open frame arranged at one end of the connecting part, an opening of the open frame is provided at the opening, a clamping tongue is slidably provided inside the open frame, the clamping tongue is pushed toward the opening and closing part by an elastic member, and is used for clamping the handle of the dumbbell with the opening and closing part.
[0007] As a further optimization scheme of the present invention, the opening and closing part is a rotary lock assembly, including a hinged end and a lock end respectively arranged at both ends of the open frame, wherein the hinged end is hingedly provided with a lock plate, and the free end of the lock plate away from the hinged end is aligned with the lock end and then locked by a fixing device. In this scheme, the opening and closing part is arranged as a rotary lock assembly. When the dumbbell needs to be connected to the transfer structure, the lock plate is first released, and then the lock plate is opened by rotating. After the dumbbell handle is placed in the open frame, the lock plate is closed and locked, and the pressing tongue presses the dumbbell handle under the action of the spring to complete the connection.
[0008] As a further optimization scheme of the utility model, the fixing device includes a pin slidably arranged in the locking end, the free end of the locking plate is provided with a slot, a pin spring for pushing the pin into the slot is provided inside the locking end, and a pulling head for pulling out the pin is provided at the end of the pin. The opening and closing of the locking plate is realized by the pin, and the pin is pushed into the slot by the pin spring to lock the free end of the locking plate. When the locking plate needs to be opened, the pin can be pulled out by the pulling head.
[0009] As a further optimization scheme of the utility model, a pair of protrusions are provided on one side surface of the locking plate for clamping the dumbbell handle. In order to adapt to dumbbell handles of different sizes, the dumbbell handle is clamped by the protrusions and the arc-shaped pressing tongue.
[0010] As a further optimization scheme of the utility model, the opening and closing part is a latch, and both ends of the open frame are provided with latching holes corresponding to the latch, which are used to insert the latch and clamp the latch. In order to simplify the structure in this scheme, the opening and closing part is set as a latch, and the opening and closing of the open frame is directly controlled by plugging and pulling out the latch.
[0011] As a further optimization scheme of the utility model, the clamping tongue limits the sliding direction through a sliding member, wherein the sliding member is slidably connected to the inside of the connecting part, and a limiting groove is provided on the side of the sliding member, and a limiting bolt corresponding to the limiting groove is provided on the surface of the open frame. The limiting bolt enters the limiting groove and can slide in the limiting groove, and limits the stroke of the sliding member.
[0012] In order to apply the above-mentioned dumbbell-barbell conversion structure, the utility model also proposes a barbell, including a barbell conversion rod and a transfer structure located at both ends of the barbell conversion rod, and the two transfer structures are both clamped with dumbbells. The barbell uses dumbbells as counterweights, and does not need to be equipped with a barbell gravity plate, which saves space and is easy to disassemble and store. The dumbbells are fixed to both ends of the barbell. During installation, the dumbbells are placed vertically upward and the side of the open frame is used to support the weight of the dumbbells, while the clamping tongue and the opening and closing part will not bear this weight, or the weight borne is very small and will not counteract the clamping force of the clamping tongue and the opening and closing part.
[0013] As a further optimization solution of the utility model, the barbell conversion rod includes a main rod body and a foam tube sleeved on the surface of the main rod body. The foam tube can improve the grip feel.
[0014] As a further optimization scheme of the utility model, the main rod body and the connecting part are rotationally connected via a connecting shaft, and a damping structure for increasing the rotational resistance is provided between the main rod body and the connecting part. Since the barbell needs to maintain the orientation of the dumbbells during training, and the angle of the barbell conversion rod may change due to the training posture, the holding part needs to have a relative rotation structure with the adapter structure, and a damping structure is provided to prevent excessive rotation.
[0015] The beneficial effects of the utility model are:
[0016] The utility model adopts a transfer structure to use dumbbells as counterweights for the barbell, and fixes the dumbbells on both ends of the barbell conversion rod. There is no need to additionally equip the barbell with gravity plates, and only needs to equip the dumbbell with gravity blocks, thereby saving space. By arranging an open frame and an elastically retractable clamping tongue, the utility model is convenient for disassembly and easy for storage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0026] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0027] Example 1
[0028] like Figure 1-4As shown, a dumbbell-barbell transition structure includes a connecting portion 1 and an open frame 2 arranged at one end of the connecting portion 1, an opening of the open frame 2 is provided with an opening and closing portion, a clamping tongue 42 is slidably provided on the inner side of the open frame 2, the clamping tongue 42 is arc-shaped, and the clamping tongue 42 is pushed toward the opening and closing portion by an elastic member 43, and the elastic member 43 is a spring, which is used to clamp the handle of the dumbbell 7 with the opening and closing portion.
[0029] The opening and closing part is a rotating lock assembly 3, including a hinged end 31 and a lock end 32 respectively arranged at both ends of the open frame 2, wherein the hinged end 31 is hingedly provided with a lock plate 33, and the free end of the lock plate 33 away from the hinged end 31 is aligned with the lock end 32 and then locked by a fixing device. In this scheme, the opening and closing part is set as a rotating lock assembly 3. When the dumbbell 7 needs to be connected to the transfer structure, the lock of the lock plate 33 is first released, and then the lock plate 33 is opened by rotating. After the handle of the dumbbell 7 is placed in the open frame 2, the lock plate 33 is closed and locked, and the pressing tongue 42 presses the handle of the dumbbell 7 under the action of the elastic member 43, and the connection is completed.
[0030] Furthermore, the fixing device includes a pin 34 slidably set in the locking end 32, a slot 37 is set at the free end of the locking plate 33, a pin spring 35 is set inside the locking end 32 for pushing the pin 34 into the slot 37, and a pull head 36 is set at the end of the pin 34 for pulling out the pin 34. The opening and closing of the locking plate 33 is realized by the pin 34. The pin 34 is pushed into the slot 37 by the pin spring 35 to lock the free end of the locking plate 33. When the locking plate 33 needs to be opened, the pin 34 can be pulled out by the pull head 36.
[0031] A pair of protrusions 38 are provided on one side surface of the locking plate 33 for clamping the dumbbell 7 handle. In order to adapt to the dumbbell 7 handles of different sizes, the dumbbell handle is clamped by the protrusions 38 and the arc-shaped pressing tongue 42.
[0032] The clamping tongue 42 limits the sliding direction through the sliding member 41, wherein the sliding member 41 is slidably connected to the inside of the connecting part 1, and a limiting groove 45 is set on the side of the sliding member 41, and a limiting bolt 44 corresponding to the limiting groove 45 is set on the surface of the open frame 2. The limiting bolt 44 enters the limiting groove 45 and can slide in the limiting groove 45, and limits the stroke of the sliding member 41, and the sliding member 41 can be clamped and fixed by tightening the limiting bolt 44.
[0033] Example 2
[0034] like Figure 5As shown, unlike Example 1, the opening and closing part in this embodiment is a latch 5, and both ends of the open frame 2 are provided with snap-in holes corresponding to the latch 5, which are used to insert the latch 5 and snap the latch 5. In order to simplify the structure in this solution, the opening and closing part is set in the form of a latch 5, and the opening and closing of the open frame 2 is directly controlled by plugging and pulling out the latch 5. The latch 5 and the snap-in hole are snap-fitted and will not fall out naturally after insertion.
[0035] In order to apply the above dumbbell-barbell conversion structure, the utility model also proposes a barbell, such as Figure 6-8 As shown, it includes a barbell conversion rod 6 and a transfer structure located at both ends of the barbell conversion rod 6, and the two transfer structures are both clamped with dumbbells 7. When the dumbbells 7 are clamped, they are vertically oriented, and the open frame 2 is located at the upper end of the handle of the dumbbell 7. The lower surface of the gravity block at the upper end of the dumbbell 7 is in contact with the open frame 2. The barbell uses the dumbbell 7 as a counterweight, so there is no need to additionally equip the barbell with a gravity plate, which saves space. It is also easy to disassemble and store. The dumbbells 7 are fixed to both ends of the barbell conversion rod 6, and by pointing the dumbbells 7 vertically upward, the side of the open frame 2 is used to support the weight of the dumbbells 7, and the clamping tongue 42 and the opening and closing part will not bear this weight, or the weight borne is very small and will not counteract the clamping force of the clamping tongue 42 and the opening and closing part.
[0036] Since the barbell requires more weight than the dumbbell, when the dumbbell is made into a barbell, the dumbbell's gravity block can be used to increase the dumbbell's counterweight, and then the dumbbell can be used as the barbell's counterweight.
[0037] In order to improve the grip feel, the barbell conversion rod 6 includes a main rod body 61 and a foam tube 62 sleeved on the surface of the main rod body 61 .
[0038] Since the barbell needs to maintain the direction of the dumbbell 7 during training, and the angle of the barbell conversion rod 6 may change due to the training posture, the holding part needs to have the ability to rotate relative to the adapter structure. For this purpose, the main rod body 61 and the connecting part 1 are rotationally connected via a connecting shaft 63. For easy disassembly and assembly, the connecting shaft 63 is rotationally connected to the connecting part 1 and is threadedly connected to the main rod body 61. Furthermore, a damping structure 64 for increasing the rotational resistance is provided between the main rod body 61 and the connecting part 1.
[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
