Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.

Float switch and support

Referring to fig. 1-6, schematic diagram of the float switch installation structure convenient for assembling and positioning according to the present invention includes: float switch 1 and support 2, float switch 1 includes: a float switch mounting plate 11, a support 12 with one end connected with the mounting plate 11, and a float 13 sleeved on the support 12, wherein two opposite sides of the float switch mounting plate 11 in the width direction are respectively provided with a guide groove 111, and an elastic positioning piece 112 (for example, a positioning column, see fig. 2-5) is arranged in the plane of the mounting plate; the bracket 2 has two opposite sides capable of being inserted into the guide slot 111 in a sliding manner and a limiting hole 21 capable of accommodating the elastic positioning piece 112; when the opposite side edges slide a predetermined distance along the guide groove 111, the elastic positioning member 112 is deformed to be received in the limiting hole 21 to limit the sliding insertion. Because the elastic positioning piece 112 and the spacing hole 21's of supporting setting, thereby make the utility model discloses a float switch can get into spacing hole 21 through elastic positioning piece 112 after elastic deformation when inserting the support, plays better limiting displacement to the direction of motion, and it is simpler and economic for operation processes such as screw-up.

It should be noted that the "width direction of the float switch mounting plate 11" in the present invention refers to a direction perpendicular to the extending direction of the guide groove 111 (see fig. 2) on the plane of the float switch mounting plate 11; accordingly, a direction parallel to the extending direction of the guide groove 111 on the plane of the float switch mounting plate 11 may also be referred to as "the longitudinal direction of the float switch mounting plate 11".

(II) sliding insertion and limiting of bracket to float switch mounting plate

Referring to fig. 2-6, the elastic positioning element 112 includes a positioning portion 1121 and a spring portion 1122, the positioning portion 1121 is connected to the spring portion 1122, and the spring portion 1122 is connected and fixed to the mounting plate 11; when the two opposite sides slide along the guide groove 111 for a predetermined distance, the elastic sheet is deformed to make the positioning portion 1121 be received in the limiting hole 21 to limit the sliding insertion. After the elastic positioning piece 112 is sleeved into the limiting hole 21 upwards, the sliding of the float switch is limited, the whole process is simple, the device is economical, the positioning effect is good, and the device is not easy to fall off.

Preferably, referring to fig. 2, when the elastic sheet portion 1122 is not deformed by an external force, the upper surface of the elastic sheet portion is parallel to the plane of the mounting plate 11, so that the bracket can be inserted quickly, and the parallel arrangement of the elastic sheet portion can balance the force applied to the elastic sheet portion, regardless of whether the bracket is inserted into or withdrawn from the float switch mounting plate, so as to avoid too large or too small pressure on the bracket contact surface caused by the elastic positioning element in the insertion or withdrawal process. The excessive pressure hinders the motion of the bracket and causes the elastic positioning piece to be easily worn, and the insufficient height of the elastic positioning piece sleeved into the limiting hole causes the elastic positioning piece to be easily separated from the limiting hole.

Preferably, referring to fig. 4, the upper surface of the elastic positioning member 112 has a predetermined inclination angle with respect to the plane of the mounting plate 11, so that the limiting hole 21 can be more conveniently inserted into the elastic positioning member 112 under the guidance of the upper surface of the elastic positioning member.

Preferably, referring to fig. 6, the included angles between the front end side edge of the bracket 2 in the sliding insertion direction and the two opposite side edges are arc-shaped lead angles 23, so as to avoid the interference between the front end of the bracket and the side walls of the guide groove 111 during the forward movement, thereby facilitating the rapid insertion of the bracket.

Preferably, referring to fig. 3(1), the guide groove 111 has a second chamfered portion 113 at the entrance of the bracket 2 for sliding insertion, so as to avoid interference of the side wall at the entrance of the guide groove 111 with the insertion of the bracket 2, thereby facilitating the rapid insertion of the bracket.

Referring to fig. 3(1) and (2), there are two embodiments of the arrangement positions of the elastic positioning members 112 in the plane of the mounting plate 11. Wherein FIG. 3(1) shows: the elastic positioning member 112 is located on the first half side of the plane of the mount plate 11 in the slide insertion direction. FIG. 3(2) shows: the elastic positioning member 112 is located on the rear half side of the plane of the mount plate 11 in the slide insertion direction. In the present invention, the forward direction of the slide insertion is defined as "forward".

Preferably, as shown in fig. 3(1), the elastic positioning member 112 is disposed on the first half side in the sliding insertion direction in the plane of the mounting plate 11. In the process of installation and fixation, the friction distance and time between the lower bottom surface of the bracket and the top surface of the elastic positioning piece 112 are reduced, and the top of the elastic positioning piece is prevented from being worn under excessive friction (for example, the top of the elastic positioning piece is shortened), so that the limiting effect when the elastic positioning piece is sleeved in the limiting hole 21 is influenced (namely, the elastic positioning piece is easier to separate from the limiting hole 21).

(III) sliding exit of the bracket to the float switch mounting plate

Contrary to the above-mentioned sliding insertion process, when the bracket is withdrawn to the float switch mounting plate by sliding, the elastic positioning member 112 is pressed to be disengaged from the limit hole 21, so that the bracket 2 can be withdrawn from the float switch mounting plate 11 by sliding along the guide groove 111.

Preferably, referring to fig. 3(1) and (2), the side of the resilient positioning element 112 remote from the plane of the mounting plate 11 is provided with a relief guide surface 1123. 1123 may be a plane or a curved surface, and due to the arrangement of the withdrawing guide surface, the elastic positioning element 112 is conveniently withdrawn from the position-limiting hole 21 during the detachment process, so as to avoid interference of the top edge of the elastic positioning element 112 with the withdrawal of the elastic positioning element from the position-limiting hole 21.

The utility model discloses an on the other hand provides an air conditioner (as shown in fig. 1), has evaporimeter 3, evaporimeter support frame 4 and float switch mounting structure, and evaporimeter 3 is fixed in evaporimeter support frame 4, float switch mounting structure and 4 fixed connection of evaporimeter support frame.
