Description

A new type of armpit crutch

[technical field]

The utility model relates to a novel armpit crutch.

[Background technique]

The existing armpit crutch is a combination of two-tube upper bracket and two-tube lower bracket, and the height can be adjusted between the upper and lower brackets, and the handshake is fixed between the two tubes of the upper bracket, and the bottom of the lower bracket is a Y-shaped bracket , the sleeve is equipped with an adjustment rod, and the underarm crutches in the prior art are fixed by handshake, so that the length between the support part and the handshake is fixed. For users whose arms are too long or too short, they cannot use force well when using crutches. Simultaneously, the armpit crutch in the prior art is socketed through a plurality of support rods, which wastes materials and is bulky.

[utility model content]

The utility model overcomes the disadvantages of the above-mentioned technologies, and provides a new type of underarm crutch, which uses a single support rod and directly connects the support rod with the handshake through the joint assembly. The structure is simple, and it is more convenient for the user to walk around.

In order to achieve the above object, the utility model adopts the following technical solutions:

A new type of underarm crutch, comprising a support rod 1, the top of the support rod 1 is connected with an underarm support part 2, the bottom of the support rod 1 is provided with an adjustment rod 3, and the support rod 1 is provided with multiple A handshake height adjustment through hole 4 arranged along the length direction of the support rod 1, the outer sleeve of the support rod 1 is connected with a sliding sleeve 5 that can slide back and forth along the support rod 1, the sliding sleeve 5 is provided with a handshake 6, and the sliding sleeve 5 is provided with a handshake 6. The sleeve 5 is provided with a handshake positioning through hole 51 aligned with the handshake adjustment through hole 4, the handshake height adjustment through hole 4 and the handshake positioning through hole 51 are connected to a positioning rod 72 for positioning the sliding sleeve 5 on the support rod 1 .

The positioning rod 71 is a screw, and the other end of the screw is connected with a nut 72 .

A nut is provided inside the handshake 6, and the positioning rod 71 passes through the handshake positioning through hole 51 and the handshake height adjustment through hole 4 in order to connect with the nut.

The bottom end of the support rod 1 is provided with a plurality of height adjustment positioning holes 11 , and the adjustment rod 3 is provided with a spring pin 31 fitted with the height adjustment positioning holes 11 .

The bottom of the adjusting rod 3 is provided with a non-slip pad 8 .

The 2 sets of underarm support parts are provided with air-permeable cushions.

The beneficial effects of the utility model are:

1. The utility model uses a single support rod to connect with the adjustment rod, which saves materials and improves economic benefits. In addition, the double support rod structure has many vulnerable points for the armpit crutches. The two joints between the upper and lower support rods When one of the socket points between the support rod and the adjustment rod is damaged, the armpit crutch cannot be used. The armpit crutch with a single support rod structure has only one socket point between the support rod and the adjustment rod, which is more secure. At the same time, it can be used When the user uses the utility model, it is easier to find the stress point of the underarm crutch, and it is not easy to lose balance.

2. The utility model directly locks the support rod and the handshake through the joint assembly, which is more suitable for users with different arm lengths. When the user uses the utility model, he can adjust the length between the appropriate support part and the handshake. It is more stable, and at the same time, it is more suitable for the strength and stretching of the arm muscles, reducing the burden on the arms.

[Detailed ways]

Below in conjunction with accompanying drawing and embodiment of the present utility model, further describe in detail:

Embodiment one:

As shown in Figure 1, a new type of underarm crutch is characterized in that it includes a support rod 1, the top of the support rod 1 is connected with an underarm support part 2, and the bottom of the support rod 1 is covered with an adjustment rod 3 , the single support rod saves materials better, improves economic benefits, reduces vulnerable points, and at the same time it is easier to find support points when using it, and it is more stable when walking. The support rod 1 is provided with multiple The set handshake height adjustment through hole 4, the outer sleeve of the support rod 1 is connected with a sliding sleeve 5 that can slide back and forth along the support rod 1, the sliding sleeve 5 is provided with a handshake 6, and the sliding sleeve 5 is provided with a handshake. The adjustment through hole 4 is aligned with the handshake positioning through hole 51 , and the handshake height adjustment through hole 4 and the handshake positioning through hole 51 are connected with a positioning rod 72 for positioning the sliding sleeve 5 on the support rod 1 .

Wherein, the positioning rod 71 is a screw rod, and the other end of the screw rod is connected to the nut 72 , and the distances between the handshake height adjustment through hole 4 and the supporting part 2 are not equal.

When the position of the handshake 6 needs to be adjusted, the nut 72 only needs to be unscrewed from the positioning rod 71, and the positioning rod 71 is unloaded from the handshake height adjustment through hole 4 and the handshake positioning through hole 51, and then the position of the handshake 6 is adjusted so that The handshake positioning through hole 51 corresponds to the handshake height adjustment through hole 4 on the support rod 1. After passing through the positioning rod 71, the nut 72 can be tightened.

Embodiment two:

A nut is arranged inside the handshake 6, and the positioning rod 71 passes through the handshake positioning through hole 51 and the handshake height adjustment through hole 4 to be connected with the nut in sequence. When the position of the handshake 6 needs to be adjusted, the positioning rod 71 is arranged on the Unscrew the nut in the handshake, and after adjusting the position of the handshake 6, directly insert the positioning rod 71 through the handshake positioning through hole 51 and the handshake height adjustment through hole 4 and then tighten it.

The bottom end of the support rod 1 is provided with a plurality of height positioning holes 11, and the adjustment rod 3 is provided with a spring pin 31 fitted with the height adjustment positioning holes 11, and the spring pin 31 is embedded with the positioning holes 11 of different heights. Combined with changing the length of the underarm crutches, it is more suitable for users of different heights.

The bottom of the adjusting rod 3 is provided with an anti-skid pad 8, which increases the friction between the adjusting rod 3 and the ground, and prevents the user from slipping when walking.

The support part 2 is covered with a breathable soft pad, so that the user can use force better and is more conducive to dissipating the heat between the armpit and the support part 2 during long-term use.
