[0075] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0076] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0077] The present application will be further described below with reference to the drawings and specific embodiments, but is not limited by the present application.

[0078] Embodiment 1

[0079] This embodiment relates to the balloon volume adjusting device of the present application.

[0080] One illustrative embodiment of the present application is as follows: Figure 1As shown, a balloon volume adjustment device 100 includes a connecting unit 110, an extension unit 120, and a positioning unit 130. The connecting unit 110 is removably disposed on the handle unit of a handheld balloon device; the extension unit 120 is disposed on one side of the connecting unit 110 and connected to it; the positioning unit 130 is movably disposed on the extension unit 120, and is limitedly connected to the extension unit 120, and abuts against the actuation unit of the handheld balloon device, for limiting the position of the actuation unit of the handheld balloon device to adjust the inflation volume of the balloon unit of the handheld balloon device.

[0081] like Figure 2 As shown, the connecting unit 110 includes a first clamping element 111 and a second clamping element 112. The first clamping element 111 is removably disposed at the bottom end of the handle unit of the handheld balloon device, and the first end of the first clamping element 111 is connected to the extension unit 120; the second clamping element 112 is removably disposed at the top end of the handle unit of the handheld balloon device, and the second end of the second clamping element 112 is movably connected to the second end of the first clamping element 111.

[0082] In some of these embodiments, the first clamping element 111 includes, but is not limited to, a first clamping handle and a first clamping rod.

[0083] Generally, the second clamping element 112 is hinged to the first clamping element 111. Specifically, the first clamping element 111 and the second clamping element 112 rotate relative to each other, thereby increasing or decreasing the distance between the first end of the first clamping element 111 and the first end of the second clamping element 112. When the distance between the first end of the first clamping element 111 and the first end of the second clamping element 112 gradually increases to a preset level, the handle unit of the handheld balloon device can be placed between the first clamping element 111 and the second clamping element 112. Then, when the distance between the first end of the first clamping element 111 and the first end of the second clamping element 112 gradually decreases to a preset level, the first clamping element 111 and the second clamping element 112 respectively clamp the upper and lower ends of the handle unit.

[0084] In some embodiments, the second clamping element 112 includes, but is not limited to, a second clamping handle and a second clamping rod.

[0085] Furthermore, the connecting unit 110 also includes an elastic element 113. The elastic element 113 is disposed between the first clamping element 111 and the second clamping element 112.

[0086] Generally, the elastic element 113 is disposed between the second end of the first clamping element 111 and the second end of the second clamping element 112, and is used to provide elastic force or tension to limit the relative position of the first clamping element 111 and the second clamping element 112.

[0087] Specifically, when the distance between the first end of the first clamping element 111 and the first end of the second clamping element 112 gradually increases to a preset level, the elastic element 113 is stretched by force and provides a pulling force to the first clamping element 111 and the second clamping element 112 so that the first clamping element 111 and the second clamping element 112 tend to move closer to each other; when the first clamping element 111 and the second clamping element 112 clamp the handle unit, the elastic element 113 is stretched by force and provides a pulling force to the first clamping element 111 and the second clamping element 112 so that the first clamping element 111 and the second clamping element 112 tightly clamp the handle unit, preventing the first clamping element 111 and the second clamping element 112 from separating from the handle unit.

[0088] In some of these embodiments, the elastic element 113 includes, but is not limited to, a spring.

[0089] Furthermore, the connecting unit 110 also includes a limiting element 114. The limiting element 114 is disposed at the first end of the second clamping element 112 and is limitedly connected to the handle unit of the handheld balloon device to limit the relative position with the handle unit of the handheld balloon device.

[0090] Generally, the limiting element 114 and the second clamping element 112 are integrally formed.

[0091] Generally, the limiting element 114 can lock the reserved limiting groove and reserved limiting hole of the handle unit, thereby limiting the relative position of the connecting unit 110 and the handle unit and preventing relative displacement between the connecting unit 110 and the handle unit.

[0092] In some of these embodiments, the limiting element 114 includes, but is not limited to, a limiting hook.

The first guide element 122 is disposed through the main body element 121 and is slidably connected to the positioning unit 130, for allowing the positioning unit 130 to reciprocate along the axial direction of the main body element 121.

[0094] Specifically, the second end of the main body element 121 is connected to the first end of the first clamping element 111.

[0095] Generally, the main body element 121 and the first clamping element 111 are integrally formed.

[0096] In some of these embodiments, the cross-section of the main element 121 is arc-shaped.

[0097] In some of these embodiments, the main body element 121 includes, but is not limited to, the guide rail body.

[0098] The first guide element 122 is disposed through the upper and lower surfaces of the main body element 121.

Generally, the width of the first guide element 122 is smaller than the width of the main body element 121, the length of the first guide element 122 is smaller than the length of the main body element 121, and the height of the first guide element 122 is equal to the height of the main body element 121.

[0101] In some of these embodiments, the first guide element 122 includes, but is not limited to, a guide rail.

[0102] Furthermore, the extension unit 120 also includes several indicator elements. These indicator elements are distributed on the side of the main body element 121 and are used to indicate the balloon volume or the amount of fluid injected.

[0103] Several indicator elements are spaced apart along the length of the main element 121.

[0104] In some of these embodiments, the indicating element includes, but is not limited to, a scale.

[0105] like Figure 4 As shown, the positioning unit 130 includes a movable element 131 and an abutting element 132. The movable element 131 is rotatably and movably disposed on the extension unit 120; the abutting element 132 is movably disposed at the lower end of the extension unit 120 and is rotatably connected to the movable element 131, and is used to reciprocate in the vertical direction under the action of the movable element 131 to abut or move away from the extension unit 120.

[0106] Specifically, the movable element 131 is rotatably and movably disposed on the first guide element 122; the abutting element 132 is movably disposed at the lower end of the main body element 121, and is used to reciprocate in the vertical direction under the action of the movable element 131 to abut or move away from the main body element 121.

[0107] In some embodiments, the movable element 131 includes an operating member and a threaded rod. The operating member is movably disposed at the upper end of the main body element 121; the threaded rod is disposed at the lower end of the operating member and is movably connected to the first guide element 122 and rotatably connected to the abutment element 132, for rotating relative to the abutment element 132 under the action of the operating member to cause the abutment element 132 to reciprocate in the vertical direction.

[0108] The dimensions of the operating element match the dimensions of the first guide element 122. Generally, the radial dimension (such as diameter, length, and width) of the operating element is greater than the width of the first guide element 122. That is, the operating element cannot enter the interior of the first guide element 122.

[0109] In some embodiments, the operating elements include, but are not limited to, an operating panel.

[0110] The dimensions of the threaded rod are matched with the dimensions of the operating part. Generally, the radial dimension of the threaded rod is smaller than the radial dimension of the operating part, and the axial dimension of the threaded rod is larger than the axial dimension of the operating part.

[0111] The dimensions of the threaded rod are matched with the dimensions of the first guide element 122. Generally, the radial dimension of the threaded rod is not greater than the width of the first guide element 122, and the axial dimension of the threaded rod is greater than the height of the first guide element 122.

[0112] In some of these embodiments, the threaded rod includes, but is not limited to, a threaded rod.

[0113] Generally, the abutting element 132 is threadedly connected to the movable element 131.

[0114] In some embodiments, the abutting element 132 includes an abutting member and a threaded hole. The abutting member is movably disposed at the lower end of the main body element 121; the threaded hole penetrates the abutting member and is threadedly connected to the movable element 131, and is used to drive the abutting member to reciprocate in the vertical direction under the action of the movable element 131.

[0115] Specifically, the threaded hole component is threadedly connected to the threaded rod component.

[0116] The dimensions of the abutment are matched with the dimensions of the first guide element 122. Generally, the radial dimension of the abutment is greater than the width of the first guide element 122. That is, the abutment cannot enter the interior of the first guide element 122.

[0117] In some embodiments, the abutment includes, but is not limited to, abutment blocks and abutment discs.

[0118] The dimensions of the threaded hole part are matched with the dimensions of the abutment part. Generally, the radial dimension of the threaded hole part is smaller than the radial dimension of the abutment part, and the axial dimension of the threaded hole part is equal to the axial dimension of the abutment part.

[0119] The dimensions of the threaded hole are matched with the dimensions of the moving element 131. Generally, the radial dimension of the threaded hole is equal to the radial dimension of the threaded rod, and the axial dimension of the threaded hole is smaller than the axial dimension of the threaded rod.

[0120] In some of these embodiments, the threaded hole component includes, but is not limited to, a threaded hole.

[0121] Furthermore, the positioning unit 130 also includes a second guide element 133. The second guide element 133 is disposed on one side of the abutment element 132 and is slidably connected to the extension unit 120 to prevent the abutment element 132 from rotating.

[0122] Specifically, the second guide element 133 is slidably connected to the first guide element 122.

[0123] More specifically, the second guide element 133 is disposed on one side of the abutment.

[0124] Generally, the second guide element 133 and the abutment element 132 are integrally formed.

[0125] In some of these embodiments, the longitudinal section of the structure formed by the second guide element 133 and the abutment element 132 is L-shaped or concave.

[0126] The dimensions of the second guide element 133 are matched with the dimensions of the abutment element 132. Generally, the axial dimension of the second guide element 133 is larger than the axial dimension of the abutment element.

[0127] The dimensions of the second guide element 133 are matched with the dimensions of the first guide element 122. Generally, the radial dimension of the second guide element 133 is not greater than the width of the first guide element 122, and the axial dimension of the second guide element 133 is not greater than the height of the first guide element 122.

[0128] In some embodiments, there are two second guide elements 133. The two second guide elements 133 are symmetrically arranged on both sides of the abutment element 132.

[0129] In some of these embodiments, the top tip of the second guide element 133 remains inside the first guide element 122 even when the abutting element 132 does not abut against the main body element 121.

[0130] In some of these embodiments, the second guide element 133 includes, but is not limited to, a guide post.

[0131] Furthermore, the positioning unit 130 also includes a buffer element 134. The buffer element 134 is movably disposed at the upper end of the extension unit 120, rotatably connected to the movable element 131, and abuts against the actuation unit of the handheld balloon device.

[0132] Specifically, the buffer element 134 is movably disposed at the upper end of the main body element 121 and abuts against the main body element 121.

[0133] More specifically, the buffer element 134 is fitted with a threaded rod and is located between the lower end of the operating element and the upper end of the main body element 121.

[0134] In some embodiments, the buffer element 134 is interference-fitted with the movable element 131 (threaded rod). The purpose of this design is to allow the buffer element 134 to rotate with the movable element 131, i.e., the buffer element 134 and the movable element 131 remain relatively stationary.

[0135] The dimensions of the buffer element 134 are matched with the dimensions of the moving element 131. Generally, the radial dimension of the outer edge of the buffer element 134 is greater than the radial dimension of the moving element, and the radial dimension of the inner edge of the buffer element 134 is not greater than the radial dimension of the threaded rod.

[0136] In some embodiments, the buffer element 134 is not limited to a buffer sleeve, such as a rubber sleeve, a silicone sleeve, etc.

[0137] Furthermore, the positioning unit 130 also includes an anti-detachment element. The anti-detachment element is disposed at the bottom end of the movable element 131 and located at the lower end of the abutment element 132, and is used to prevent the movable element 131 from separating from the abutment element 132.

[0138] Specifically, the anti-loosening element is located at the bottom end of the threaded rod.

[0139] The dimensions of the anti-detachment element are matched with the dimensions of the movable element 131. Generally, the radial dimension of the anti-detachment element is larger than the radial dimension of the threaded rod.

[0140] In some of these embodiments, the anti-detachment element includes, but is not limited to, an anti-detachment plate.

[0141] The method of using this utility model is as follows:

[0142] (a) Clamping

[0143] Pressure is applied to the first clamping element 111 or the second clamping element 112 to cause the first clamping element 111 and the second clamping element 112 to rotate relative to each other;

[0144] Place the handle unit of the handheld balloon device between the first clamping element 111 and the second clamping element 112, and make the limiting element 114 lock the handle unit in the reserved limiting groove or reserved limiting hole.

[0145] When the pressure applied to the first clamping element 111 or the second clamping element 112 is released, under the action of the elastic element 113, the first clamping element 111 and the second clamping element 112 rotate relative to each other and press tightly against the handle unit.

[0146] (II) Position Adjustment

[0147] Twist the movable element 131 in the first direction (e.g., clockwise) to make the abutment element 132 move downward in the vertical direction;

[0148] Stop twisting the movable element 131 when the abutting element 132 is not in contact with the lower end of the main body element 121;

[0149] As needed, the movable element 131 is pushed to move between the first end and the second end of the first guide element 122. When the movable element 131 reaches a preset position (such as an indicator element), the pushing of the movable element 131 is stopped.

[0150] Twist the movable element 131 in the second direction (e.g., counterclockwise) to make the abutment element 132 move upward in the vertical direction;

[0151] When the abutting element 132 abuts against the lower end of the main body element 121, stop twisting the movable element 131 and complete the position adjustment of the positioning unit 130;

[0152] At this time, the actuation unit of the handheld balloon device presses against the buffer element 134.

[0153] The technical effects of this utility model are as follows:

[0154] 1) The balloon volume adjustment device and the handheld balloon device can be firmly fixed together through the connecting unit, and no relative movement will occur;

[0155] 2) By cooperating with the extension unit and the positioning unit, the volume of liquid injected into the balloon can be precisely controlled, and the degree of balloon inflation can be precisely controlled.

[0156] 3) During use, the operator does not need to observe the injection volume of the liquid injection device, reducing the difficulty of operation for the operator.
