[ detailed description ] embodiments

The technical solutions of the embodiments of the present invention are explained and explained below with reference to the drawings of the embodiments of the present invention, but the embodiments described below are only preferred embodiments of the present invention, and not all embodiments. Based on the embodiments in the embodiment, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention.

In the following description, the terms "inside", "outside", "upper", "lower", "left", "right", and the like, which indicate orientations or positional relationships, are used to indicate orientations or positional relationships based on the drawings, and are only used for convenience in describing embodiments and simplifying the description, but do not indicate or imply that the indicated device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

The first embodiment is as follows:

as shown in fig. 1 to 3, the present embodiment shows an electric push rod assembly, which includes an electric push rod and an external connector, where the electric push rod includes an outer tube 1 and an inner tube 2, the internal structure further includes a driving motor, a rotating lead screw and a transmission nut, the driving motor drives the rotating lead screw to rotate, the rotation lead screw drives the transmission nut to move along an axial direction of the rotating lead screw when rotating, and the transmission nut is fixed relative to the inner tube 2, so that the inner tube 2 makes reciprocating telescopic motion relative to the outer tube 1 under the driving of the driving motor, the specific structure and principle are disclosed in the prior art in a large number, and details are not described herein, and in the present embodiment, the electric push rod assembly further includes a connecting member 3, the connecting member 3 is disposed between the outer tube 1 and the external connector, the connecting member 3 includes a first mounting end and a second mounting end, the first mounting end is used for mounting the, the outer connector is not shown in fig. 1 to 3, and the second mounting end comprises a catch 301 provided with an opening through which it is snap-fitted onto the outer tube 1 in the radial direction of the outer tube 1.

In this embodiment, improve connecting element 3, the utility model provides a connecting element 3 includes first installation end and second installation end, and first installation end is used for being connected with the external connector, and the second installation end then includes a draw-in groove 301 of taking the open-ended, and when the equipment, the second installation end passes through along the radial direction of outer tube 1 the opening clamps to outer tube 1, and the mode of equipment promptly clamps from the lateral part of outer tube 1, just so need not embolia from the tip. Even if electric putter's tip has installed hand and has revolved release additional, perhaps electric putter's tip has been connected to and has waited to drive when the animal on, does not all influence being connected of connecting elements 3 and outer tube 1, and the suitability is stronger, utilizes this kind of draw-in groove 301 of taking the open-ended moreover, also need not just can easily install with the help of other instruments, and the equipment is very convenient. For the openings in the present embodiment, it is preferable to set the distance h between the openings to 1cm to 4cm, for example, 1.5cm, 2cm, etc., and too small a distance h between the openings causes difficulty in clamping, while too large a distance h between the openings causes high probability of detachment.

The second installation end comprises two clamping jaws 31, the inner walls of the two clamping jaws 31 form the clamping groove 301, and the clamping groove 301 is in interference fit with the outer pipe 1. The lateral clamping of the outer tube 1 is realized through the two clamping claws 31, and the structure is relatively simple. In addition, for laminating outer tube 1 that makes draw-in groove 301 can be better, the inner wall of two jack catchs 31 is the arc, this is because present electric putter's outer tube 1 can be made circular or similar circular cambered surface usually, and establishes the arc with the inner wall of two jack catchs 31 also correspondingly, can make draw-in groove 301 can with the better laminating of outer tube 1 to it is better to make the stability of clamping.

For the external connector, the external connector may be a power adapter or a controller, or other types of electrical devices, due to the environment in which the power push rod is used.

For the first mounting end, because the type and shape of the external connector are slightly different, the positioning manner adopted by the first mounting end in this embodiment is also relatively universal, the first mounting end in this embodiment includes a bottom plate 34 and at least two limiting pieces arranged on the periphery of the bottom plate 34, the limiting pieces are provided with a protruding piece 35 for clamping the top surface of the external connector, the at least two limiting pieces are mainly used for positioning the outer peripheral surface of the external connector in shape, and the protruding piece 35 is mainly used for limiting the top surface of the external connector to prevent the external connector from being separated.

Preferably, in the present embodiment, four corners of the bottom plate 34 are provided with four limiting pieces, which are equivalent to limiting four corners, and two of the four limiting pieces located on the same side are the positioning limiting pieces 32, and the other side is the elastic limiting piece 33. Referring to fig. 3, the cross section of the positioning limiting piece 32 is similar to an L shape, so that the positioning limiting piece can well perform a double-sided positioning function, the elastic variable ability of the positioning limiting piece is relatively weak, the elastic deformation ability of the elastic limiting piece 33 is strong, the elastic limiting piece can deform toward a single side, and during assembly, one side of the outer connector can be firstly abutted to the positioning limiting piece 32 and then clamped by the elastic limiting piece 33.

On the basis of this connecting element 3, the utility model provides an electric putter subassembly can install the hand at electric putter's inner tube 2 tip and revolve release, and this kind of hand revolves release's external diameter and is greater than the external diameter of inner tube 2, also can not influenced, needs to explain that, does not set up the hand and revolves release in the show of this embodiment.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
