Description

Inflator device with support frame

The invention relates to an inflator device, in particular to an inflator device with a support.

An existing pump device is suitable for pumping up an object to be inflated, and includes a base and an inflator installed on the base. In order to be relatively stable and not tip over when pumping up the inflatable object (such as a bicycle), the pump device further includes two detachable foot rods that are screwed on the base and suitable for supporting the ground.

Although the foot rods can be supported against the ground when assembled on the base, the pump device as a whole is not easily toppled due to the tilt of the pump during the pumping process. However, when the pump device is not normally used, in order to reduce the space occupied when storing the pump device, the user must first separate the foot rod from the base, which is relatively time-consuming to operate; in addition, separate from the base The legs are also easily lost due to careless storage.

Therefore, the purpose of the present invention is to provide a pump device with a support that can overcome at least one of the disadvantages of the prior art.

Therefore, the pump device with a support of the present invention is suitable for pumping an inflatable object. The pump device with a support includes a pump unit and a support unit.

The pump unit is suitable for pumping up the inflatable object, and has two storage slots spaced apart from each other, and two limit slots spaced apart from the storage slots.

The supporting unit includes two supports connected to the pump unit. The supporting frames can respectively extend into the storage grooves and close to the storage positions of the pump unit relative to the pump unit, and support the support on the ground and be respectively confined in the expansion of the limiting grooves Rotate between positions.

The effect of the present invention is that by using the design of the supports, the storage grooves and the limit grooves, the supports can be rotated between the storage position and the unfolded position, which is very convenient to use; When in the position, it can be restricted by the limit slots to stably support the ground. When in the storage position, the supports are still connected to the pump unit to avoid losing the supports.

Referring to Figures 1, 2 and 5, an embodiment of the inflator device with a support of the present invention is suitable for pumping up an inflatable object (not shown). In this embodiment, it is an inflator device for a bicycle. Tire pump up. The pump device with a support includes a pump unit 1 and a supporting unit 2 connected to the pump unit 1.

The pump unit 1 includes a base 11 suitable for being placed on a ground, a pump 12 vertically assembled on the base 11 and suitable for pumping inflatable objects, and a screw-locked cover on the bottom side of the base 11 The bottom cover 13 and a hanger 14 assembled on the pump 12 and a pressure gauge 15 for measuring the pressure of the inflatable object.

The base 11 includes a bottom shell 111 and an inner shell 112 assembled on the bottom shell 111. The bottom shell 111 and the inner shell 112 are jointly formed with two receiving grooves 113 spaced apart from each other, two limiting grooves 114 spaced apart from the receiving grooves 113, and one formed on the bottom side from the receiving grooves 113 One of the grooves 113 extends straight to the other sliding groove 115. Each receiving slot 113 penetrates through the top and bottom and extends to the outer peripheral surface 116 of the base 11. Each limiting groove 114 is formed on the bottom side and is not connected to the top side, and extends to the outer peripheral surface 116 of the base 11, and communicates with the sliding groove 115 and sandwiches a predetermined angle.

The pump 12 includes a base 121 assembled on the top side of the base 11, a barrel 122 that is installed upright on the base 121, a piston 123 movably arranged in the barrel 122, and a piston 123 connected to the barrel 122. The top side of the piston 123 protrudes from the barrel 122 for a user to hold to move the handle 124 of the piston 123, and a handle 124 assembled on the barrel 122 and communicated with the barrel 122 for connecting the The inflatable product delivers the gas formed when the piston 123 moves up and down the barrel 122 to the gas pipe 125 of the inflatable product.

The support unit 2 includes two bases 11 assembled in the pump unit 1 and can be rotated between a storage position close to the pump unit 1 and an unfolded position supported on the ground (as shown in FIG. 4) Support 21.

Each support frame 21 includes a chute 115 that is generally short columnar and is assembled to the base 11 and can move relative to the corresponding receiving slot 113 and is shielded by the bottom cover 13 and a moving block 211 that is rod-shaped and can be A leg 212 pivotally connected to the moving block 211 and capable of moving between the corresponding receiving slot 113 and the corresponding limiting slot 114.

When the supporting unit 2 is in the storage position, the moving blocks 211 of the supports 21 are located at intervals in the sliding groove 115, and each moving block 211 protrudes adjacent to one end of the outer peripheral surface 116 of the base 11 The sliding groove 115 is located in the corresponding receiving groove 113. The leg 212 of each bracket 21 extends into and is vertically embedded in the corresponding receiving slot 113, and the bottom end is pivotally connected to the corresponding moving block 211, and vertically abuts with the corresponding moving block 211 In the pump 12.

Referring to FIGS. 2 to 4, when using the pump device with a support, first pivot the foot rods 212 in the storage position away from the barrel 122 of the pump 12 to level it. It is in a straight line with the moving blocks 211; then the foot rods 212 are pushed toward each other, so that the moving blocks 211 move toward each other along the chute 115 to adjust the distance between the moving blocks 211 until the moving blocks 211 Leaning against each other, and the moving blocks 211 are completely located in the sliding groove 115; afterwards, the foot rod 212 is rotated downward to move away from the receiving grooves 113, and moved to the top of the limiting groove 114 , And then respectively extend into the limit slots 114, so that the supports 21 can be rotated from the storage position to the unfolded position.

Referring to Figures 4 to 6, when the supports 21 are in the deployed position, since the limiting grooves 114 are not connected to the top side of the base 11, the limiting grooves 114 can be limited in the deployed position The foot rods 212 cannot be pulled up directly and leaned against the pump 12, so that the foot rods 212 stably support the ground.

After that, the user can hook the hanger 14 of the pump unit 1 to a frame of the bicycle (for example, a seat stay and a chain stay), and connect the air pipe 125 to the tire to perform Inflate, and use the pressure gauge 15 to measure the air pressure of the tire during the inflating process. During the pumping process, since the support brackets 21 at the unfolded position are supported on the ground, the stability of the pump device with support can be improved to avoid shaking and falling.

In summary, the pump device with a support of the present invention utilizes the design of the supports 21 and the base 11, so that the supports 21 can extend into the receiving grooves 113 to be close to the pump 12 The storage position and the limit are rotated between the unfolded positions of the limit slots 114, and the operation is very simple and convenient. In addition to effectively reducing the space required for storage, the device also has high stability, and the supports 21 are still connected to the pump unit 1 when in the storage position, and will not be lost due to careless storage. It can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
