Abstract

The invention relates to an inflator, which comprises a cylinder body, an inflating rod and a handle, wherein the bottom end of the inflating rod is movably inserted into the cylinder body, the top end of the inflating rod forms a convex ring, a first clamping piece is formed on the convex ring, a fixed groove is formed on the handle, a stop ring is formed on the wall surface of the fixed groove, a second clamping piece is formed corresponding to the first clamping piece, the second clamping piece is aligned to the first clamping piece, the fixed groove is forced into the convex ring of the inflating rod, the stop ring is stopped at the bottom edge of the convex ring, and the first limiting piece and the second limiting piece are clamped and fixed; the convex ring of the inflating rod is abutted in the fixing sleeve of the handle by the abutting ring, and the first limiting piece and the second limiting piece are clamped and fixed, so that the handle does not rotate relative to the inflating rod, and the defect that the handle is easy to rotate in a screwing and fixing mode and the force is not easy to be applied by a user is avoided.

Description

Pump

Technical field

The present invention relates to a kind of pump, espespecially a kind of pump, its handle can firmly be fixed on inflating rod, not easily relatively with inflating rod rotates, and allows user be easy to force.

Background technique

The pump of market today can roughly be divided into two kinds, vertical type pump and Portable inflating pump, and wherein, Portable inflating pump structure is comparatively simple, as shown in Figure 6, includes:

One cylindrical shell 50, one end is provided with a check valve 51;

One inflating rod 60, its bottom is inserted in this cylindrical shell movably, and bottom is provided with a piston (not shown), and inflating rod top bar wall is then formed with outside thread;

On the other hand 70, be formed with a fixed groove 71, and fixed groove 71 is formed with this externally threaded internal thread in inflating rod top of coupling, and is sheathed on the top of inflating rod 60 with this fixed groove 71, and make with internal thread and external thread spiro fastening hand fix with inflating rod 60 70.

The object that above-mentioned pump arranges hand handle is to provide user and is convenient to grip, inflate to push away, to draw inflating rod, but due to user push away, draw inflating rod time, may exerting a force, it is in one's hands 70 to rotate, within making, spiral shell is loose 70 rotate relative with inflating rod 60 for the hand of external thread spiro fastening, user is caused not easily to grab steady hand 70 forces, again hand need be screwed tight with inflating rod 60 70, and pump is after use a period of time, also easily because spiral shell pine often screws tight handle and inflating rod, and the solid power of spiral shell is reduced, need improve.

Summary of the invention

Rotating because the inflating rod of above-mentioned pump is relative easily there being spiral shell loose with hand, causing the technological deficiency that user not easily exerts a force, main purpose of the present invention proposes a kind of pump, and its inflating rod and hand, firmly fixing mutually, not easily rotate relatively.

The technical way used for reaching above-mentioned purpose makes this pump include:

One cylindrical shell, one end is provided with a check valve;

One inflating rod, its bottom is inserted in this cylindrical shell movably, and bottom is provided with a piston, and inflating rod top bar wall is then formed with a bulge loop, and this bulge loop is formed with one first clipping device;

Handle on the other hand, be formed with a fixed groove, this fixed groove internal face forms one and supports stop ring, and to forming one second clipping device by the first clipping device, the first clipping device of inflating rod is aimed at the second clipping device, and fixed groove is forced into the bulge loop of inflating rod bar wall, make to stop ring to the bulge loop root edge terminating in inflating rod top, and the second clipping device and the first clipping device are fixed.

Inflating rod is fixed on the stop ring that supports of fixed cover in hand handle with hand by the present invention, and fasten with first and second bounding means, make hand handle fix with inflating rod and can not relatively rotate, so, can avoid because spiral shell pine causes handle to rotate, allow user be easy to grip and force in time inflating.

Embodiment

Refer to Fig. 1 and Fig. 2, pump of the present invention includes:

One cylindrical shell 10, one end is provided with a check valve 11;

One inflating rod 20, its bottom is inserted in this cylindrical shell 10 movably, and bottom is provided with a piston 21, inflating rod 20 top bar wall is then formed with a bulge loop 22, and this bulge loop 22 is formed with one first clipping device 23, in the present embodiment, this first clipping device 23 is a fin;

On the other hand 30, be formed with a fixed groove 31, this fixed groove 31 internal face forms one and supports stop ring 32, and to forming one second clipping device 33 by the first clipping device 23, the first clipping device 23 of inflating rod 20 is aimed at the second clipping device 33, and fixed groove 31 is forced into the bulge loop 22 of inflating rod 20 bar wall, with as shown in Figure 3, what make fixed groove 31 supports stop ring 32 to bulge loop 22 root edge terminating in inflating rod 20 top, and as shown in Figure 4, second clipping device 33 and the first clipping device 23 are fixed, in the present embodiment, this hand has transverse part 301 and a longitudinal part 302 30 in T font, this fixed groove 31 is formed on the end face of this longitudinal part 302, or can be as shown in Figure 5, this hand is cylinder type 30, this fixed groove 31 is formed at cylinder type hand the end face of 30, and hand is formed with multiple on-slip burr 303 the outer surface of 30, this second clipping device 33 correspondence first clipping devices 23 are a groove, be fastened in groove for fin.

The second described clipping device 33 also can change fin into, and this first clipping device 23 correspondences change groove into for engaging with the second clipping device 23.

The inflating rod 20 of pump of the present invention supports stop ring 32 to terminating in inflating rod 20 bulge loop 22 root edge with fixed groove 31, make inflating rod 20 to terminating in fixed groove 31, and be fixed togather by first and second clipping device 23,33, hand can not be rotated relative to inflating rod 20 30; Compared within the pump of external thread spiro fastening, the engaging of first and second bounding means 23,33 does not have and makes because of spiral shell pine the defect that hand can rotate relative to inflating rod 20 30, and after Long-Time Service, also without the problem that the solid power of spiral shell reduces, and rotate because spiral shell is loose the defect making user not easily exert a force with hand to improve inflating rod.
